Description

Portable Electrolyzed Water Sprayer

The present invention relates to an electrolyzer that electrolyzes water to produce an active substance. In particular, the present invention relates to a portable electrolyzed water sprayer suitable for carrying around at the time of going out and spraying an electrolyzed water to any part to sterilize and deodorize the part.

Conventionally, a hypochlorous acid generating sprayer is known as a hospital, a facility where people enter and leave, or a device for disinfecting fingers and the like in a home (for example, see Patent Document 1).

The hypochlorous acid generation sprayer of Patent Document 1 electrolyzes a solution of a chlorine compound contained in a container to generate hypochlorous acid water, and sprays it from a spray part of the container.

Specifically, the hypochlorous acid generating sprayer includes a container containing a solution of a large amount of chlorine compounds, and a trigger sprayer detachably attached to the upper end of the container. Then, the hypochlorous acid generating sprayer is configured to pump a solution of 0.1 ml to 1 ml of a chlorine compound from the container and spray it from the nozzle of the trigger spray.

Also, a portable electrolytic water sprayer 21 shown in FIG. 7 has been proposed (see, for example, Patent Document 2).

FIG. 7 is a cross-sectional view of a conventional portable electrolytic water sprayer 21 disclosed in Patent Document 2. As shown in FIG.

As shown in FIG. 7, the electrolytic water sprayer 21 has a cylindrical outer appearance, and is configured by arranging a cylindrical water tank portion 22, a power supply portion 23, and a spray mechanism portion 24 inside. The water tank portion 22 is open at the top and is disposed in the middle of the electrolytic water sprayer 21. The power supply unit 23 is disposed below the electrolyzed water sprayer 21, and the spray mechanism unit 24 is disposed above the electrolyzed water sprayer 21. The water tank unit 22 includes a tubular electrolytic unit 25 disposed inside. The electrolytic unit 25 is disposed in the axial direction of the water tank unit 22. An electrode 26 is disposed in the inside of the electrolytic unit 25 to electrolyze water in the water tank unit 22 flowing from the lower part. Thus, ozone water is generated. The generated ozone water is sprayed from the nozzle at the tip of the spray mechanism 24 and is configured to be disinfected.

However, since the hypochlorous acid generating sprayer of Patent Document 1 is used by being installed on a shelf of a hospital, a facility, or a home, it has a large overall shape and is unsuitable for portable use. Furthermore, hypochlorous acid to be sprayed is weak in oxidizing power. Therefore, while sterilization takes time, it is difficult to deodorize aging odor and mold odor that are difficult to be decomposed.

Moreover, the electrolytic water sprayer of patent document 2 sprays ozone water, and disinfects. Ozone water to be sprayed has high oxidizing power and is effective. In other words, ozone water can disinfect bacteria on hands, toilet seats, tables, etc. in a short time, and is suitable for deodorizing such as age-related odor and mold odor.

However, ozone water is consumed in ozone when disinfecting fabric products such as clothes because ozone water does not have the persistence of oxidizing power. For this reason, it is difficult to secure the sterilization and deodorizing performance of clothes.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited by the embodiment.

Embodiment 1
Hereinafter, the portable electrolytic water sprayer according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 3.

FIG. 1 is a cross-sectional view showing an internal configuration of the portable electrolytic water sprayer according to the first embodiment. FIG. 2 is an exploded perspective view showing the relationship between the electrolytic unit and the power supply unit of the portable electrolytic water sprayer. FIG. 3: is sectional drawing which shows the electrode structure of the same electrolysis part.

The portable electrolyzed water sprayer 1 (hereinafter abbreviated as “electrolyzer 1”) shown in FIG. 1 is formed in a tubular external shape. In the cylindrical shape, any cross-sectional shape such as a cylindrical shape, an oval shape, or a polygonal shape can be selected.

The electrolytic device 1 is configured by arranging a cylindrical tank portion 2 at an intermediate portion, a power supply portion 3 at a lower portion, and a push type spray mechanism portion 4 at an upper portion.

In the electrolytic device 1 of the first embodiment, the external shape of the tank portion 2 and the power supply portion 3 is formed in a cylindrical shape having substantially the same diameter (including the same diameter).

The power supply unit 3 is detachably screwed to the lower part of the tank unit 2. Thereby, the tank unit 2 and the power supply unit 3 are held in a watertight manner. Further, the spray mechanism unit 4 is detachably screwed to the upper portion of the tank unit 2. Thereby, the tank part 2 and the spray mechanism part 4 are held in a watertight manner. That is, the inside of the tank unit 2 constitutes a water reservoir. Then, by removing the spray mechanism unit 4 and supplying water, the water is stored in the tank unit 2.

In the tank unit 2, a cylindrical electrolytic unit 5 is disposed along the axial direction of the tank unit 2 at a cylindrical radial center. The water of the tank unit 2 flows into the electrolytic unit 5 from the lower inflow hole 5E (see FIG. 2) and flows out to the spray mechanism unit 4 from the upper surface opening 5F (see FIG. 2). Therefore, the electrolytic device 1 is configured such that the water levels of the electrolytic unit 5 and the tank unit 2 become the same level in the vertical arrangement state in which the push type spray mechanism unit 4 is up.

The electrolysis unit 5 accommodates an electrode 6 for producing electrolytic water for producing electrolytic water so as to be immersed in the water flowing into the inside. The electrode 6 is composed of a first electrode 6A and a second electrode 6B. In the electrode 6 of the first embodiment, the first electrode 6A constitutes an ozone generating electrode that generates ozone, and the second electrode 6B constitutes a chlorine material generating electrode for generating water containing a chlorine material. Do.

Specifically, as shown in FIGS. 2 and 3, in the electrolytic unit 5, the first electrode 6A and the second electrode 6B face each other at a predetermined distance, and are accommodated in the cylindrical body 5P. . Thereby, the electrolysis chamber 5S which becomes a flow passage of water is formed between the first electrode 6A and the second electrode 6B. At this time, if water is present in a portion other than the electrolysis chamber 5S formed between the first electrode 6A and the second electrode 6B, the water is not electrolyzed and therefore contains ozone or a chlorine substance. It will not be water. Therefore, when the water containing no ozone or chlorine substance is sprayed from the push type spray mechanism unit 4, the sterilization effect by the electrolytic device 1 is lost. Therefore, the electrolytic unit 5 is provided with a seal configuration so that water does not flow through the portion other than the portion between the first electrode 6A and the second electrode 6B. This prevents the presence of water in the portion other than the electrolysis chamber 5S.

In the electrode 6, the first electrode 6A and the second electrode 6B are accommodated in the axial direction of the electrolytic device 1, that is, the electrode 6 is parallel to the axial direction of the tank portion 2.

The electrode 6 is formed of, for example, two to five first electrodes 6A and second electrodes 6B. The electrode 6 may be configured by a pair of one first electrode 6A and one second electrode 6B.

In order to effectively generate electrolytic water for sterilization, the electrode 6 of the first embodiment has a first electrode 6A of one sheet and a second electrode 6B on both sides thereof as a preferred embodiment of the electrode 6. The configuration is such that a predetermined interval is provided.

The electrolytic device 1 further includes a control unit 7 that supplies power from the power supply unit 3 to the electrode 6 and controls the power supply unit 3. The control unit 7 controls to invert the polarity of the power (voltage and current) supplied to the first electrode 6A and the second electrode 6B. Specifically, when the control unit 7 controls the power supply unit 3 so that the first electrode 6A becomes an anode, ozone water is generated. Further, when the control unit 7 controls the power supply unit 3 so that the second electrode 6B becomes an anode, water containing a chlorine substance is generated.

At this time, switching of the polarity supplied to the first electrode 6A and the second electrode 6B constituting the electrode 6 is selected by the switching unit 8 disposed in the electrolytic device 1. That is, when the user operates the switching unit 8 (for example, a push operation), the control unit 7 controls to switch the polarity of the power supplied to the first electrode 6A and the second electrode 6B. Thereby, the generation of ozone water and the generation of water containing a chlorine substance are selected. As a result, it is possible to select the production of active species suitable for the object of eradication and deodorization.

In addition, you may provide light-emitting devices (not shown), such as LED, in the electrolysis apparatus 1, for example. That is, the light emitting device changes the color and the light emission intensity of the light emitting device according to the switching operation of the switching unit 8. As a result, it is possible to visualize the operation mode such as, for example, the generation mode of ozone water or the generation mode of water containing a chlorine substance to notify the user. As a result, the user can effectively generate an active species suitable for the object.

As described above, the electrolytic device 1 of Embodiment 1 is configured.

Below, the structure of the electrode 6 of the electrolysis part 5 of the electrolysis apparatus 1 is demonstrated concretely.

As shown in FIG. 3, in the electrode 6 of the first embodiment, the second electrode 6B is formed on both sides of the first electrode 6A, for example, a resin such as polypropylene (PP) or acrylonitrile butadiene styrene resin (ABS) or the like. It arrange | positions via the spacer 5B of insulating materials, such as ceramics. As a result, the first electrode 6A and the second electrode 6B are disposed opposite to each other at a substantially uniform (including uniform) predetermined interval (for example, about 0.1 mm to 1 mm). At this time, the non-facing surface of the second electrode 6B that does not act on the electrolysis with the first electrode 6A is covered with a cylindrical body 5P made of an insulating material such as a resin such as PP or ABS. The cylindrical body 5P is made of, for example, a heat-shrinkable tube made of synthetic resin such as vinyl chloride, silicon, or fluorine. Therefore, when the heat-shrinkable tube is shrunk by heating, the heat-shrinkable tube is closely attached to the periphery of the second electrode 6B, and the cylindrical body 5P is formed so as to enclose the electrode 6.

Thereby, the electrolysis chamber 5S which becomes a flow passage of water is formed between the 1st electrode 6A and the 2nd electrode 6B which oppose via the spacer 5B. Then, by supplying power of a predetermined polarity to the electrode 6, the water present in the electrolysis chamber 5S is electrolyzed. As a result, ozone or water containing a chlorine substance can be generated according to the supplied polar power, and each electrolyzed water can be effectively generated.

In the first embodiment, control unit 7 controls power supply from power supply unit 3 to first electrode 6A and second electrode 6B only when spray mechanism unit 4 is operated. preferable. That is, hypochlorous acid produced with the time of electrolysis increases. Thus, the control described above suppresses fluctuations in the operating time of the concentration of water containing a substance to be sprayed such as ozone and a chlorine substance such as hypochlorous acid. As a result, water containing a chlorine substance such as ozone or hypochlorous acid can be stably generated at a constant concentration.

The lower end of the electrode 6 is watertightly sealed to the power source 3 and the upper end is watertightly sealed to the spray mechanism 4 in a state where the spray mechanism 4 is attached to the tank 2. Thereby, when ozone water etc. are sprayed by the action | operation of the spraying mechanism part 4, the electrolysis part 5 is substantially comprised by the cylindrical shape which water does not flow through parts other than the electrolysis chamber 5S.

That is, the electrolysis chamber 5S constitutes a generation region of electrolyzed water. Therefore, electrolyzed water is generated between the plate-shaped first electrode 6A and the plate-shaped second electrode 6B on both sides of the electrode 6. Furthermore, the electrolysis chamber 5S constitutes a flow path for flowing the water of the tank unit 2 to the spray mechanism unit 4. Therefore, the configuration of the flow path of water flowing from the tank portion 2 to the spray mechanism portion 4 can be simplified. Thereby, a compact configuration in which the electrolytic unit 5 is disposed at the center of the tank unit 2 can be realized.

The first electrode 6A of Embodiment 1 functions as an ozone generating electrode as described above. Therefore, the first electrode 6A includes an electrode catalyst formed of, for example, tantalum oxide or the like on the surface of a metal substrate of, for example, titanium. Further, the second electrode 6B functions as a chlorine material generation electrode. Therefore, the second electrode 6B is formed of an alloy layer of platinum and iridium.

As described above, the electrode 6 of the electrolytic unit 5 of the electrolytic device 1 is configured.

Next, the mechanism of ozone generation in the first electrode 6A using the above-described tantalum oxide as an electrode catalyst will be described.

When power is supplied to the first electrode 6A, a thin depletion layer is formed at the interface between the surface of the electrode catalyst tantalum oxide (eg, tantalum oxide) and the cleaning water. In that state, when water is electrolyzed, electrons are generated by the reaction of water with the first electrode 6A. The generated electrons pass through the depletion layer formed on the tantalum oxide surface by tunneling. As a result, the potential of the first electrode 6A at which the exchange of electrons is performed becomes equal to or higher than the oxidation-reduction potential of ozone, and it is considered that ozone can be generated. As a result, the ozone generation reaction is more efficiently performed to generate ozone.

Although tantalum oxide is used as the electrode catalyst for generating ozone of the first electrode 6A in the above, it is conceivable to use lead dioxide, diamond, platinum or the like, for example. However, in the case of lead oxide, there are concerns about environmental and human effects. In the case of diamond or platinum, the cost is high and the efficiency of ozone generation is low.

Therefore, in the first embodiment, tantalum oxide is used as the electrode catalyst. That is, tantalum oxide can generate ozone at a lower current density than platinum. In addition, tantalum oxide has a feature that the generation efficiency of ozone increases as the current density decreases. In addition, tantalum oxide has high oxygen overvoltage.

Therefore, ozone can be generated at a low voltage of, for example, about 1.5 V or so, without generating oxygen, by the electrode catalyst of tantalum oxide. In particular, compared to platinum, tantalum oxide can generate ozone with a power of about one-fourth. Therefore, it becomes possible to operate the electrolysis device 1 with a battery or a rechargeable battery.

In addition to the above, a mixture of tantalum oxide and platinum may be used as the electrode catalyst of the first electrode 6A, and the same effect can be obtained.

Next, the configuration of the second electrode 6B will be described more specifically.

The second electrode 6B functions as a chlorine substance generation electrode. Therefore, the second electrode 6B of the first embodiment is configured of an electrode catalyst made of an alloy layer of platinum and iridium.

Even with platinum alone, hypochlorous acid can be produced. However, by forming an alloy layer of platinum and iridium, the generation efficiency of hypochlorous acid can be further improved. Therefore, the second electrode 6B of the first embodiment is configured by an electrode catalyst in which 60% of platinum and 40% of iridium are mixed in a molar ratio. By setting the electrode catalyst of the second electrode 6B to the above-described material composition, the generation efficiency of hypochlorous acid is improved by about 3.5 times as compared with the platinum-only electrode catalyst. The reason is presumed to be that the oxygen overpotential is lowered by the electrode catalyst.

In addition to the above, the electrode catalyst of the second electrode 6B may include, for example, a noble metal such as platinum or a noble metal oxide such as ruthenium, rhodium, or ruthenium.

According to the above configuration, the portable electrolyzed water sprayer 1 (electrolytic device 1) of Embodiment 1 is used for applications that use both ozone water and water containing a chlorine substance (for example, hypochlorous acid). Accordingly, it can be selected and generated by the switching operation of the switching unit 8.

For example, in the case of producing ozone, ozone has high oxidizing power and immediate effect. Therefore, it becomes possible to oxidatively decompose, for example, nonenal or mold smell which is a main component of aging odor which is difficult to be oxidatively decomposed, and further sebum components. Further, ozone can eliminate bacteria attached to a toilet seat, a table, hands, toys, etc. in a short time.

However, since ozone is highly reactive, as described above, ozone is not suitable for use in disinfecting bacteria attached to clothes or the like and in deodorizing tobacco odor. In this case, the use of hypochlorous acid having high oxidation persistence is more suitable. Therefore, the hypochlorite is generated by switching the polarity of the power supplied to the electrode 6 of the electrolytic device 1 in order to eliminate bacteria attached to clothes or the like and to deodorize the tobacco odor. Thereby, according to the use to be used, etc., one electrolysis device 1 can produce suitable electrolysis water.

As described above, the electrolytic device 1 of Embodiment 1 is configured.

Below, the effect | action and effect of the ozone water and hypochlorous acid water which are produced | generated with the electrolyzer 1 provided with the said structure are demonstrated concretely.

First, the sterilization effect of the electrolytic device 1 of Embodiment 1 was evaluated.

Specifically, first, in a petri dish to which E. coli is attached, ozone water (for example, containing ozone at a concentration of 0.1 to 0.4 ppm) and hypochlorous acid water (for example, a concentration of 1 to 5 ppm) 1 ml of each was sprayed with an acid), and the sterilization effect after standing for 5 seconds was evaluated. As a result, in ozone water, a high sterilization rate of 99% or more was obtained in a short time and at a concentration of 0.2 ppm. On the other hand, hypochlorous acid water had difficulty achieving a 99% eradication rate in a short time even at 2 ppm of 10 times the concentration of ozone water. This is considered to be the effect by the high oxidizing power of ozone water maintained in a short time.

Furthermore, ozone water (eg 0.4 ppm, containing ozone at a concentration of 1 ppm) and hypochlorous acid water (eg containing hypochlorous acid at a concentration of 10 ppm, 18 ppm, 30 ppm) on a cloth to which E. coli has been attached 1 ml each was sprayed, and the sterilization effect after leaving for 30 minutes was evaluated. As a result, it was difficult to achieve a 99% eradication rate with ozone water at a concentration of 1 ppm. On the other hand, hypochlorous acid water at a concentration of 18 ppm achieved a sterilization rate of 99% or more. That is, since ozone is highly reactive, it reacts with the cloth to decrease its concentration, and it is considered that the oxidizing power does not act on bacteria inside the cloth. On the other hand, since hypochlorous acid is not as high in reactivity as ozone, it is considered that hypochlorous acid can be caused to act on microbes inside the cloth while maintaining its oxidizing power even if consumed somewhat by the cloth.

Next, the deodorizing effect of the electrolytic device 1 of Embodiment 1 was evaluated.

Specifically, 1 ml of each of ozone water and hypochlorous acid water prepared to the same concentration as above was sprayed on a cloth impregnated with tobacco odor, and the deodorizing effect after standing for 30 minutes was evaluated. did. As a result, with ozone water, the deodorizing effect could not be confirmed. On the other hand, it was confirmed that hypochlorous acid water has a deodorizing effect equivalent to that of a commercial clothes deodorant.

As described above, it has been found that the ozone water and hypochlorous acid water produced by the electrolytic device 1 exert the action and effect appropriately in accordance with applications such as sterilization and deodorization.

In the electrolytic device 1 of the first embodiment, a scale component such as calcium adheres to the surface of the electrode 6 usually during long-term use. Therefore, the electrolytic action of the electrolytic device 1 is inhibited by the attached scale component.

Therefore, in general, the inhibition of the electrolysis action by the scale component is suppressed, for example, by the following method.

Specifically, the spray mechanism unit 4 is sometimes removed from the tank unit 2 from time to time. Next, water and citric acid are put into the tank portion 2 and the inside of the tank portion 2 is washed with citric acid. Thereby, citric acid can dissolve and remove scale components such as calcium attached to the surface of the electrode 6. As a result, the electrolytic action of the electrolytic device 1 is maintained for a long time.

Moreover, there is also a method shown below as a method of removing other scale components.

Specifically, the controller 7 reverses the polarity of the power applied to the first electrode 6A and the second electrode 6B. Thereby, the adhesion of the scale component to the first electrode 6A and the second electrode 6B is suppressed.

First, power is applied by connecting the first electrode 6A as an anode and the second electrode 6B as a cathode. In this connected state, when electrolyzed, cations such as calcium and magnesium contained in the water to be treated are electrically attracted to the second electrode 6B which is a cathode. That is, the surface of the second electrode 6B becomes alkaline by the electrolysis. Therefore, calcium and magnesium in the water to be treated are precipitated on the surface of the second electrode 6B as calcium hydroxide and calcium hydroxide. Moreover, when it reacts with a carbonate ion, calcium and magnesium adhere to the surface of the second electrode 6B as calcium carbonate and magnesium carbonate.

Therefore, the control unit 7 inverts the polarity of the power applied to the first electrode 6A and the second electrode 6B, for example, every predetermined time or every predetermined period, and performs electrolysis. As a result, it is possible to suppress the formation and adhesion of calcium hydroxide and calcium hydroxide generated on the surface of the second electrode 6B and scale components such as calcium carbonate and magnesium carbonate.

Further, the scale component attached to the surface of the second electrode 6B can be removed by the same control as described above.

Specifically, due to the polarity inversion of the electrode 6, the vicinity of the second electrode 6B has a strongly acidic pH. Therefore, the scale component deposited on the surface of the second electrode 6B is dissolved or peeled off from the electrode interface. Thereby, the scale component can be removed from the surface of the second electrode 6B.

Although the case where the first electrode 6A is an anode and the second electrode 6B is a cathode has been described above as an example, the case where the first electrode 6A is a cathode and the second electrode 6B is an anode is described above. The opposite control operation can remove the scale component of the first electrode 6A.

That is, the adhesion of the scale component to the electrode 6 can be suppressed by the above operation. Therefore, it is possible to prevent, for example, the clogging of the electrolysis chamber 5S constituting the flow passage due to the adhesion of the scale component. Thereby, the deterioration of the performance of the electrode 6 due to the adhesion of the scale component can be suppressed. As a result, stable performance and durability of the electrolytic device 1 can be ensured over a long period of time.

Moreover, in Embodiment 1, although the example which comprised the electrode catalyst of 1st electrode 6A with the tantalum oxide as an ozone generation electrode was demonstrated, it is not restricted to this. As an electrode catalyst, for example, a diamond electrode or the like to which conductivity is imparted by doping boron or the like to diamond which is an insulator may be used.

In the first embodiment, although an example using an alloy layer of platinum (Pt) and iridium (Ir) as the electrode catalyst of the second electrode 6B has been described, the present invention is not limited thereto. The electrode catalyst may contain, for example, other noble metals such as platinum, iridium, rhodium and ruthenium or noble metal oxides such as iridium, rhodium and ruthenium, and the same effect as the above-mentioned alloy layer can be obtained.

Second Embodiment
Hereinafter, the portable electrolytic water sprayer (electrolytic device) of Embodiment 2 of the present invention will be described. In addition, since the electrolytic device 1 of Embodiment 2 is the same as that of Embodiment 1 except the structure of 2nd electrode 6B, it demonstrates, referring FIGS. 1-3. At this time, the same components as those of the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

In the electrolytic device 1 according to the second embodiment, the first electrode 6A is an ozone generating electrode that generates ozone, and the second electrode 6B is a metal ion generating electrode for generating water containing metal ions. Configure.

Specifically, Ag ion is selected as the metal ion. Therefore, the second electrode 6B is formed of an Ag substrate.

According to this configuration, when the control unit 7 controls the power supply unit 3 so that the first electrode 6A becomes an anode, ozone water is generated. On the other hand, when the control unit 7 controls the power supply unit 3 so that the second electrode 6B becomes an anode, water containing Ag ions as metal ions is generated.

At this time, switching of the polarity supplied to the first electrode 6A and the second electrode 6B constituting the electrode 6 is selected by the switching unit 8 disposed in the electrolytic device 1. That is, when the user operates the switching unit 8 (for example, a push operation), the control unit 7 controls to switch the polarity of the power supplied to the first electrode 6A and the second electrode 6B. Thereby, the generation of ozone water and the generation of water containing metal ions such as Ag ions are selected. As a result, it is possible to select the generation of active species suitable for the object of sterilization and deodorization.

The first electrode 6A of the second embodiment functions as an ozone generating electrode as described above. Therefore, the first electrode 6A includes an electrode catalyst formed of, for example, tantalum oxide or the like on the surface of a metal substrate of, for example, titanium.

Further, the second electrode 6B functions as a metal ion generation electrode. Therefore, the second electrode 6B is made of an Ag substrate to generate Ag ions. Note that the second electrode may generate at least an Ag ion, a Cu ion, a Zn ion, or the like as a metal ion generation electrode. Therefore, the second electrode 6B may be made of, for example, a metal substrate containing Ag, Cu, Zn, or an electrode catalyst containing a metal or metal oxide of Ag, Cu, Zn, in addition to the above Ag substrate.

As mentioned above, the electrolysis device 1 of Embodiment 2 provided with the above-mentioned electrode 6 composition is constituted.

Below, the effect | action and effect of the ozone water and Ag ion water which are produced | generated with the electrolyzer 1 of the said structure are demonstrated concretely.

First, the sterilization effect of the electrolytic device 1 of Embodiment 2 was evaluated.

Specifically, first, ozone water (for example, containing ozone at a concentration of 0.1 ppm to 0.4 ppm) and Ag ion water (for example, at a concentration of 0.1 ppm to 2.0 ppm) in a petri dish to which E. coli is attached 1 ml of each was sprayed, and the sterilization effect after standing for 5 seconds was evaluated. As a result, in ozone water, a high sterilization rate of 99% or more was obtained in a short time and at a concentration of 0.2 ppm. On the other hand, it was difficult to achieve an eradication rate of 99% in a short time even at 2 ppm of Ag ion water at a concentration of 10 times that of ozone water. This is considered to be the effect by the high oxidizing power of ozone water maintained in a short time.

Furthermore, ozone water (eg 0.4 ppm, containing ozone at a concentration of 1.0 ppm) and Ag ion water (eg 0.1 ppm, 0.2 ppm, 1.0 ppm, 2.0 ppm 1 ml of each was sprayed by concentration (containing Ag ion), and the sterilization effect after standing for 3 hours was evaluated. As a result, it was difficult to achieve a 99% eradication rate with 1 ppm ozone water. On the other hand, 0.2 ppm Ag ionized water achieved a sterilization rate of 99% or more. That is, since ozone is highly reactive, it reacts with the cloth to decrease its concentration, and it is considered that the oxidizing power does not act on bacteria inside the cloth. On the other hand, since Ag is not highly reactive, it is considered that it can be caused to act on bacteria inside the cloth while maintaining the oxidizing power.

Next, the deodorizing effect of the electrolytic device 1 of Embodiment 2 was evaluated.

Specifically, 1 ml of each of ozone water and Ag ion water prepared to have the same concentration as above was sprayed onto a cloth impregnated with tobacco odor, and the deodorizing effect after standing for 3 hours was evaluated. As a result, with ozone water, the deodorizing effect could not be confirmed. On the other hand, it was confirmed that Ag ionized water can obtain the same deodorizing effect as a commercially available clothes deodorant.

Next, the growth inhibitory effect of the bacteria of the electrolytic device 1 of Embodiment 2 was evaluated.

Specifically, first, 1 ml of each of ozone water and Ag ion water prepared beforehand to a concentration similar to the above was sprayed onto the cloth, and E. coli was allowed to adhere after 30 minutes. After 12 hours, the number of bacteria was counted to evaluate the growth inhibitory effect of the bacteria. As a result, in the cloth sprayed with ozone water, bacteria were proliferating. On the other hand, in the cloth sprayed with Ag ionized water, E. coli adhered in advance was disinfected, and the growth of bacteria was also suppressed. Thereby, the high antibacterial action of Ag ion water was able to be confirmed.

In the second embodiment, a configuration using an Ag substrate has been described as an example in order to generate Ag ions as the second electrode 6B. However, the present invention is not limited to this. For example, a metal substrate containing Ag or an electrode catalyst may be used, and the same effect as in the case of an Ag substrate can be obtained. In addition to the Ag substrate, a substrate containing Cu, Zn metal, a noble metal oxide, or a metal catalyst may be used as the second electrode 6B. Even in this case, the same effect as in the case of the Ag substrate can be obtained.

Third Embodiment
Hereinafter, the portable electrolytic water sprayer 11 (electrolytic device 11) of the third embodiment of the present invention will be described with reference to FIG.

FIG. 4 is a cross-sectional view showing the internal configuration of the portable electrolytic water sprayer 11 according to the third embodiment. In addition, since the electrolysis part 5 of the electrolysis apparatus 11 of Embodiment 3 is the same as that of Embodiment 1, it attaches | subjects the code | symbol same as Embodiment 1, and abbreviate | omits description.

As shown in FIG. 4, the electrolytic device 11 according to the third embodiment is formed to have a tubular or rectangular outer appearance. That is, the cross-sectional shape of the electrolyzer 11 can select arbitrary shapes, such as a cylindrical shape, an ellipse, and a polygon.

The electrolysis apparatus 11 includes an electrolysis unit 5, a tank unit 12 for storing an aqueous solution, a power supply unit 13, a push type spray unit 14, a control unit 17, a chloride supply unit 18, a pump power supply 19 and the like. . The chloride supply unit 18 is disposed adjacent to the tank unit 12 and supplies chloride ions to the tank unit 12. The control unit 17 is provided in the lower part of the tank unit 12, controls the power supplied from the power supply unit 13 to a predetermined current or voltage, and applies it to the electrolytic unit 5 provided in the tank unit 12. As a result, electrolyzed water is generated in the electrolytic unit 5. The spray unit 14 is disposed at the top of the tank unit 12 and sprays the electrolytic water generated by the electrolysis when the user pushes it.

In the electrolytic device 11 according to the third embodiment, the external shape of the tank unit 12 and the power supply unit 13 is formed to be substantially the same square (including the same square).

In the tank portion 12, the tubular electrolytic unit 5 is disposed along the axial direction of the tank portion 12 at a cylindrical radial center. The water in the tank portion 12 flows into the electrolytic portion 5 from the lower inflow hole (not shown), and flows out from the top opening (not shown) to the push type spray portion 14. Therefore, the electrolytic device 11 is configured such that the water levels of the electrolytic unit 5 and the tank unit 12 become the same level in the vertical arrangement state in which the spray unit 14 is at the top.

The chloride supply unit 18 is disposed adjacent to the tank unit 12 and includes a chloride storage tank 18a, a pump 18b, and the like. The chloride storage tank 18a stores an aqueous solution containing a high concentration of chloride ions. The pump 18 b supplies the aqueous solution containing chloride ions in the chloride storage tank 18 a to the tank unit 12. Specifically, when the user turns on (turns on) the pump power supply 19, the pump 18b converts the aqueous solution in the chloride storage tank 18a to a predetermined concentration of chloride ions. Supply into the tank unit 12.

That is, the electrolytic device 11 of the third embodiment operates when the user puts a predetermined amount of water into the tank portion 12 and turns on the pump power supply 19. Thus, the aqueous solution in the chloride storage tank 18a is configured to be supplied to the tank unit 12 by a predetermined amount.

In the chloride storage tank 18a of the third embodiment, for example, physiological saline is stored as an aqueous solution containing chloride ions.

The electrolytic unit 5 contains an electrode 6 for producing electrolytic water for producing electrolytic water so as to be immersed in the water inside the tank unit 12. As in the first embodiment, the electrolytic unit 5 includes the first electrode 6A and the second electrode 6B. Specifically, for the first electrode 6A of the electrode 6, a platinum iridium-based or platinum-rhodium-based electrode material that generates hypochlorous acid is used. On the other hand, a Ti substrate excellent in corrosion resistance is used for the second electrode 6B.

As in the first embodiment, control unit 17 controls power supply from power supply unit 13 to first electrode 6A and second electrode 6B only when spray unit 14 is operated. Is preferred. Thereby, the fluctuation | variation in the operating time of the density | concentration of hypochlorous acid water sprayed can be suppressed. As a result, hypochlorous acid water can be stably produced at a constant concentration.

Further, the control unit 17 may be configured to maintain power supply to the first electrode 6A and the second electrode 6B in the electrolytic unit 5 for a predetermined time when the user operates the spray unit 14 . Thereby, regardless of the slowing of the operation speed of the spray unit 14 pushed by the user, hypochlorous acid having a stable concentration can be generated for a certain period of time and injected. At this time, the operation of the spray unit 14 by the user may be detected by, for example, a capacitance sensor or a conductive switch installed in the spray unit 14.

As described above, the first electrode 6A of the third embodiment is formed of an electrode catalyst made of an alloy layer of platinum and iridium so as to function as a hypochlorous acid generating electrode.

As described above, the electrolytic device 11 is configured.

Next, the generation mechanism of hypochlorous acid by electrolysis when power is supplied with the first electrode 6A as an anode and the second electrode 6B as a cathode will be briefly described.

First, chloride ions contained in the aqueous solution in the tank portion 12 are oxidized by the first electrode 6A to generate chlorine, as shown in the following (Formula 1). The generated chlorine partially reacts with water to form hypochlorous acid as shown in the following (Formula 2).

^{_{^{2Cl - → Cl 2 + 2e -}}} ---------- ( Formula 1)
Cl ₂ + H ₂ O → HCl + HClO ---------- (Formula 2)
Therefore, the concentration of hypochlorous acid generated by electrolysis changes with the chloride ion concentration of the aqueous solution in the tank portion 12.

The relationship between the concentration of hypochlorous acid to be generated and the concentration of chloride ion will be described below with reference to FIG.

FIG. 5 shows the chloride ion concentration in the tank 12 and the generated hypochlorous acid concentration when varying the applied current applied from the controller 17 to the first electrode 6A and the second electrode 6B. It shows the relationship with

That is, first, the control unit 17 applies an applied current of, for example, 0.05A, 0.1A, 0.2A, and 0.3A to the first electrode 6A and the second electrode 6B. At this time, the control unit 17 controls the supply amount of the 0.8% NaCl saline solution stored in the chloride storage tank 18 a by the pump 18 b of the chloride supply unit 18. Thus, physiological saline is added to the inside of the tank 12 to adjust the chloride ion concentration in the tank 12 to, for example, 18 ppm, 50 ppm and 100 ppm. Then, for each of the chloride ion concentrations, the concentration of hypochlorous acid generated when each of the above applied currents was applied was measured.

As a result, as shown in FIG. 5, it was confirmed that the generated hypochlorous acid concentration is higher as the chloride ion concentration is higher at the same applied current. From this, it was found that when the applied current is constant, if the chloride ion concentration in the tank portion 12 varies, the generated hypochlorous acid concentration also varies.

However, the electrolytic device 11 of the third embodiment can always supply a constant NaCl solution addition amount into the tank portion 12 by the control of the pump 18 b. Therefore, the electrolytic device 11 which can generate a stable hypochlorous acid concentration can be obtained.

In addition, by storing a high concentration NaCl solution in the chloride storage tank 18a, hypochlorous acid having a predetermined concentration can be produced in the tank portion 12 with a small amount of added NaCl. Therefore, if a high concentration NaCl solution is stored in the chloride storage tank 18a first, stable electrolytic water such as hypochlorous acid can be obtained only by supplying water to the tank portion 12 for a long period of time. Can be generated. Thereby, for example, at the time of going out, electrolytic water can be easily generated only by the supply of water.

Even if the first electrode 6A is made of platinum alone, hypochlorous acid can be generated. However, by forming the first electrode 6A with an alloy layer of platinum and iridium, the generation efficiency of hypochlorous acid can be further improved. Therefore, the first electrode 6A of Embodiment 3 is formed of an electrode catalyst containing 60% of platinum and 40% of iridium in a molar ratio. By setting the electrode catalyst of the first electrode 6A to the above-described material composition, it has become possible to improve the generation efficiency of hypochlorous acid by about 3.5 times as compared with a platinum-only electrode catalyst. The reason is presumed to be that the oxygen overpotential is lowered by the electrode catalyst.

In addition to the above, the electrode catalyst of the first electrode 6A includes, for example, an electrode catalyst composed of an alloy layer of platinum and rhodium, a noble metal such as platinum, or a noble metal oxide such as iridium, rhodium or ruthenium. You may

In the third embodiment, the control unit 17 changes the applied voltage and the current to generate hypochlorous acid as an example. However, the present invention is not limited to this. For example, the control unit 17 may control to change the polarity of the power supplied to the first electrode 6A and the second electrode 6B. Thus, not only the active species generated by the first electrode 6A but also the active species that can be generated by the second electrode 6B can be generated by changing the polarity. As a result, one electrolyzer 11 can generate a plurality of active species according to the application.

In the third embodiment, the second electrode 6B is formed of a Ti substrate. However, the present invention is not limited to this. For example, tantalum oxide may be formed as an electrode catalyst on a Ti substrate. This makes it possible to generate ozone.

Therefore, the mechanism of ozone generation in the configuration using tantalum oxide for the electrode catalyst of the second electrode 6B will be described below.

First, when power is supplied to the second electrode 6B, a thin depletion layer is formed at the interface between the surface of the tantalum oxide (e.g., tantalum oxide), which is an electrode catalyst, and the cleaning water. In that state, when water is electrolyzed, electrons are generated by the reaction between the water and the second electrode 6B. The generated electrons pass through the depletion layer formed on the tantalum oxide surface by tunneling. As a result, the potential of the second electrode 6B at which the exchange of electrons is performed becomes equal to or higher than the oxidation-reduction potential of ozone, so that ozone can be generated. As a result, the ozone generation reaction is more efficiently performed to generate ozone.

Although tantalum oxide is used as the electrode catalyst for generating ozone of the second electrode 6B in the above description, it is also conceivable to use lead dioxide, diamond, platinum or the like, for example. However, in the case of lead oxide, there are concerns about environmental and human effects. In the case of diamond or platinum, the cost is high and the efficiency of ozone generation is low.

Therefore, in the second electrode 6B of Embodiment 3, tantalum oxide is used as an electrode catalyst. That is, tantalum oxide can generate ozone at a lower current density than platinum. In addition, tantalum oxide has a feature that the generation efficiency of ozone increases as the current density decreases. In addition, tantalum oxide has high oxygen overvoltage.

Therefore, ozone can be generated at a low voltage of, for example, about 1.5 V or so, without generating oxygen, by the electrode catalyst of tantalum oxide. In particular, compared to platinum, tantalum oxide can generate ozone with a power of about one-fourth. Therefore, it becomes possible to operate the electrolysis device 11 with a battery or a rechargeable battery. Thereby, it is suitable as a small-sized and portable electrolytic device 11. In addition to the above, a mixture of tantalum oxide and platinum may be used as the electrode catalyst of the second electrode 6B, and the same effect can be obtained.

According to the above configuration, the portable electrolyzed water sprayer 11 (electrolyzer 11) of the third embodiment can be used in the switching unit 8 according to the application that uses both hypochlorous acid water and ozone water. It can be selected and generated by switching operation.

As described above, the electrolytic device 11 of the third embodiment is configured.

Below, the effect | action and effect of the ozone water and hypochlorous acid water which are produced | generated with the electrolyzer 11 provided with the said structure are demonstrated concretely.

First, the sterilization effect of the electrolytic device 11 of Embodiment 3 was evaluated.

Furthermore, the cloth on which E. coli is attached contains ozone water (for example, containing 0.1 ppm and 1.0 ppm of ozone) and hypochlorous acid water (for example, containing 10 ppm, 18 ppm and 30 ppm of hypochlorous acid) 1 ml of each was sprayed, and the sterilization effect after leaving for 30 minutes was evaluated. As a result, it was difficult to achieve a 99% eradication rate with ozone water at a concentration of 1 ppm. On the other hand, hypochlorous acid water at a concentration of 18 ppm achieved a sterilization rate of 99% or more. That is, since ozone is highly reactive, it reacts with the cloth to decrease its concentration, and it is considered that the oxidizing power does not act on bacteria inside the cloth. On the other hand, since hypochlorous acid is not as high in reactivity as ozone, it is considered that hypochlorous acid can be caused to act on microbes inside the cloth while maintaining its oxidizing power even if consumed somewhat by the cloth.

Next, the deodorizing effect of the electrolytic device 11 of Embodiment 3 was evaluated.

As described above, it has been found that the ozone water and the hypochlorous acid water generated by the electrolytic device 11 appropriately exhibit the action and the effect depending on the application such as sterilization and deodorization.

In the electrolytic device 11 of Embodiment 3, scale components such as calcium adhere to the surface of the electrode 6 during long-term use. Therefore, the electrolytic action of the electrolytic device 11 is inhibited by the attached scale component.

Therefore, in general, the occurrence of the inhibition of the electrolytic action by the scale component is suppressed, for example, by the following method.

Specifically, first, the spray unit 14 is sometimes removed from the tank unit 12. Next, water and citric acid are put into the tank portion 12, and the inside of the tank portion 12 is washed with citric acid. Thereby, citric acid can dissolve and remove scale components such as calcium attached to the surface of the electrode 6. As a result, the electrolytic action of the electrolytic device 11 is maintained for a long time.

That is, the adhesion of the scale component to the electrode 6 can be suppressed by the above operation. Therefore, it is possible to prevent, for example, the blockage of the electrolysis chamber 5S constituting the flow passage due to the adhesion of the scale component. Thereby, the deterioration of the performance of the electrode 6 due to the adhesion of the scale component can be suppressed. As a result, stable performance and durability of the electrolytic device 11 can be ensured over a long period of time.

Moreover, in Embodiment 3, although the example which comprised the electrode catalyst of 2nd electrode 6B with the tantalum oxide as an ozone generation electrode was demonstrated, it is not restricted to this. For example, a diamond electrode may be used as an electrode catalyst.

Moreover, in Embodiment 3, although the structure which used Ti board | substrate was demonstrated to the example as 2nd electrode 6B, it is not restricted to this. In order to generate Ag ions, for example, the use of an Ag substrate, a metal substrate containing Ag, or an electrode catalyst may be used, and the same effect as in the case of an Ag substrate can be obtained. Furthermore, besides the Ag substrate, a substrate containing Cu, Zn metal, a noble metal oxide, or a metal catalyst may be used as the second electrode 6B. Even in this case, the same effect as in the case of the Ag substrate can be obtained.

Embodiment 4
Hereinafter, the portable electrolytic water sprayer 20 (electrolytic device 20) of the fourth embodiment of the present invention will be described with reference to FIG.

FIG. 6 is a cross-sectional view showing an internal configuration of a portable electrolytic water sprayer 20 (electrolytic device 20) according to a fourth embodiment.

The electrolytic device 20 according to the fourth embodiment is configured such that the chloride supply unit 18 according to the third embodiment is an eye drop container 18c storing an aqueous chloride solution, and the eye drop container 18c can be removed from the electrolytic device 20. This is different from the third embodiment.

With the above configuration, the electrolytic device 20 eliminates the pump 18b for automatically supplying chloride ions to the tank 12 and the pump power supply 19 according to the third embodiment, and the chloride in the tank 12 from the eye drop container 18c manually. An aqueous solution was added.

Here, the eye drop container 18c can drop a solution such as an aqueous chloride solution by directly pushing the container with a light force. Furthermore, the eye drop container 18c can prevent liquid leakage from the opening of the pressure valve when the container is restored after being pressed.

Specifically, the eye drop container 18c includes, for example, a flexible container main body that contains a drug solution, and a discharge port. The discharge port is provided in the container body, and configured to discharge the chemical solution stored in the container body.

That is, the eye drop container 18c deforms the container body by pressing. At this time, when the internal pressure of the container body becomes higher than the atmospheric pressure, the chemical solution is discharged from the discharge port. When the pressure on the container body is released, the internal pressure of the container body becomes lower than the atmospheric pressure. As a result, external air is allowed to flow into the container body from the discharge port, and the container body is restored to the shape before pressing. As a result, the eye drop container 18c is configured to add a certain amount of drug solution.

With the configuration of the eye drop container 18c, the pump 18b and the pump power supply 19 can be deleted. Therefore, the size and weight of the electrolytic device 20 can be reduced. Thereby, the convenience as the portable electrolytic device 20 is further improved.

In the fourth embodiment, a recess is provided at a position corresponding to the eye drop container 18c of the electrolytic device 20 to install the eye drop container 18c in the recess, but the present invention is not limited to this. For example, the eye drop container 18c may be attached to the outside of the electrolytic device 20, for example, like a strap. Thereby, the electrolysis device 20 of further miniaturization can be realized.

Further, by making the eye drop container 18c detachable, the cleaning property of the eye drop container 18c can be improved.

The portable electrolyzed water sprayer according to the present invention encompasses various forms in the technical scope. Therefore, the present invention is not limited to the configuration shown in the above embodiment, and can be applied to various forms of portable electrolytic water sprayers.
