[Best mode for carrying out the invention]

A washing water injector according to a preferred embodiment of the present invention, and the washing water injection The dishwasher provided with the machine will be described below.

[I] Wash water injection machine

(1) First embodiment

As shown in Fig. 1, the washing water sprayer 1 supplies one disc 2, a motor 3 for rotating the disc 2 around the central axis X1, and washing water to both sides of the disc 2. The cleaning water supply nozzles 4 and 5 are provided. The cleaning water supply nozzle 4 and the cleaning water supply nozzle 5 are united at the base. The combined base is connected to a water supply pipe (not shown).

As shown in Figs. 1 and 2, the wash water discharge ports 4a and 5a of the wash water supply nozzles 4 and 5 are located at locations offset radially outward from the center axis X1 of the disk 2. They are arranged facing each other.

The operation of the washing water injector 1 will be described.

The disk 2 is driven to rotate in the direction of the arrow in FIG. The cleaning water is supplied to both sides of the disc 2 through the cleaning water discharge ports 4 a and 5 a of the cleaning water supply nozzles 4 and 5. The washing water receives a shearing force from the disk 2 and is accelerated in the rotation direction of the disk 2. As shown by the dashed line in FIG. 2, the washing water flows radially outward on the disk 2 as a liquid film while drawing a spiral trajectory and spreading in a fan shape according to the law of inertia. . Since the wash water discharge ports 4a and 5a of the wash water supply nozzles 4 and 5 are disposed so as to face a portion offset radially outward from the central axis X1 of the disk 2, the wash water is provided. The film reaches the outer edge of the disk 2 without spreading in a large fan shape.

As shown by the alternate long and short dash line in FIG. 2, the film of the washing water gushes out of the outer edge of the disk 2 radially outward at a high speed and intensively from a relatively narrow circumferential area α. The film of washing water spouted radially outward from the circumferential area α of the outer edge of the disc 2 spreads in a fan-like manner, and is crushed to form many water droplets. Become. The water droplets formed by crushing the cleaning water film collide with the object to be cleaned placed radially outward of the region α, and clean the object to be cleaned.

The position and range of the region α are determined depending on the offset amount of the cleaning water discharge ports 4 a and 5 a outward in the radial direction from the center axis X 1 of the disk 2. If the offset amount of the wash water discharge ports 4a and 5a from the center axis X1 of the disc 2 to the radially outward direction is small, the area α is substantially the entire circumference of the outer edge of the disc 2. . As the amount of offset of the washing water outlets 4a, 5a radially outward from the center axis X1 of the disk 2 increases, the area α approaches the washing water outlets 4a, 5a. The range of the region α becomes narrow.

As shown in Fig. 2, the diameter of the disc 2 is set to 130 mm, the dimensions of the washing water discharge ports 4a and 5a are set to 1 mm (circumferential direction) x 5 mm (radial direction), The radial distance from the center axis X1 of the disc 2 at the outlets 4a and 5a is 55 mm, and the distance from the disc surfaces 2a and 2b of the wash water outlets 4a and 5a is 2 mm, and the material of the disk 2 was ABS (acrylyl tri-butadiene-styrene copolymer). The disk 2 is driven to rotate at 800 rpm, and the cleaning water (tap water) is supplied at a flow rate of 3 ^ / min through the cleaning water discharge ports 4a and 5a. b, and the amount of washing water jetted along the outer edge of the disk 2 was measured. Fig. 3 shows the distribution of the jetting amount of washing water along the outer edge of the disk 2. From FIG. 3, it can be seen that the washing water is intensively spouting from a specific circumferential area on the outer edge of the disc 2.

As shown by the alternate long and short dash line in FIG. 1, the washing water ejected from the outer edge of the surface 2a of the disc 2 and the washing water ejected from the outer edge of the surface 2b of the disc 2. Since the space yS becomes negative pressure, they are attracted to each other and converge. The converged water droplets with high kinetic energy per unit volume can efficiently clean the object to be cleaned. In the washing water injector 1, the motor 3 simply drives the disk 2 to rotate, and does not pressurize the washing water to a high pressure. Therefore, the motor 3 does not require a large motor for driving the pump of the conventional pressurized washing water injector. Therefore, the flush water injector 1 is smaller than the prior art pressurized flush water injector. A dishwasher equipped with a washing water jet 1 is smaller, has lower manufacturing and operating costs, and is less expensive to operate than a conventional dishwasher equipped with a pressurized washing water injector. Low noise. -It is not necessary to install a pump, a high-pressure water injection nozzle, a water storage tank between the water supply pipe and the pump, etc. in the washing water injector 1. As a result, the structure of the washing water injector 1 is simpler than that of the conventional pressurized washing water injector. A dishwasher equipped with a washing water jet 1 has a simpler structure than a conventional dishwasher equipped with a pressurized washing water jet, and its manufacturing cost and maintenance cost are low.

In the washing water sprayer 1, the washing water outlets 4a and 5a of the washing water supply nozzles 4 and 5 are opposed to a portion offset radially outward from the center axis X1 of the disk 2. The cleaning water supplied to the disk 2 through the cleaning water discharge ports 4a and 5a is concentrated at a relatively narrow circumferential area α on the outer edge of the disk 2 and is concentrated at high speed. Spout outward. The concentrated water droplets with large kinetic energy per unit volume can efficiently clean the object to be cleaned.

(2) Second embodiment

As shown in FIG. 4, a washing water jet 10 is composed of two laminated disks 11 and 12 coaxially laminated with a gap therebetween, and integrally formed with each other. 1 and a washing water supply nozzle that supplies washing water to both sides of the disks 1 1 and 1 2 15, 16, and 17. The cleaning water supply nozzles 15, 16 and 17 are united at the base. The combined base is connected to a water supply pipe (not shown).

As shown in Fig. 4, the cleaning water outlets 15a, 16a, and 17a of the cleaning water supply nozzles 15, 16, and 17 are located at the center axes X of the discs 11, 12 It is arranged to face the part that is offset radially outward from 2.

The operation of the washing water injector 10 will be described.

The laminated body 13 and thus the disks 11 and 12 are driven to rotate by the motor 14. Wash water is supplied to both sides of the discs 11, 12 through the wash water outlets 15 a, 16 a, 17 a of the wash water supply nozzles 15, 16, 17. The washing water receives shearing force from the disks 11 and 12, and is accelerated in the rotation direction of the disks 11 and 12. The washing water forms a liquid film while flowing in a spiral trajectory according to the law of inertia and spreading in a fan shape, and flows radially outward on the disks 11 and 12. The cleaning water film is intensively spouted radially outward at a high speed from a relatively narrow circumferential area on the outer edge of the disks 11 and 12. The cleaning water film intensively ejected radially outward from the relatively narrow circumferential area of the outer edge of the disks 11 and 12 spreads in a fan shape and is crushed into a large number of water droplets. Water droplets formed by crushing the cleaning water film collide with the object to be cleaned placed radially outward of the relatively narrow circumferential area on the outer edge of the disks 11 and 12. Clean the object to be cleaned.

As shown by the dashed line in FIG. 4, the wash water spouted from the outer edge of the surface 11a of the disk 11 and the wash water spouted from the outer edge of the surface 11b of the disk 11 The washing water ejected from the outer edge of the surface 12a of the surface 1 2a and the washing water ejected from the outer edge of the surface 12b of the disc 1 2 make the spaces 7, 5, and ε sandwiched between these washing waters. Because they are negative pressure And converge. The converged droplets of cleaning water with a large kinetic energy per unit volume can efficiently clean the object to be cleaned, two disks at the same rotation speed and the same water supply amount. The cleaning water jetting power of the cleaning water jetting device 10 of the second embodiment having 2 is larger than that of the cleaning water jetting device 1 of the first embodiment having one disk 2. The reason is that the increase in the number of disks reduces the amount of water supply per disk, reduces the slip between the washing water supplied on the disks and the rotating disks, and reduces the outer edge of the disks. It is considered that the speed of the washing water spouting from the tank increases.

As shown in Fig. 5 (a), the diameter of the disk 2 of the cleaning liquid sprayer 1 is set to 130 mm, the thickness of the disk 2 is set to 3 mm, and the size of the washing water discharge port 4a is set to 2 mm ( Circumferential direction) X 1 4 mm (radial direction), Washing water outlet 4a Disk 2 at the radial distance from center axis X1 of disk 2 at 55 mm, Washing water outlet 4a disk 2 The distance from the surface 2a was 2 mm, the washing water discharge port 5a was closed, and the material of the disk 2 was ABS. And rotating the disc 2 at 8 0 0 0 rpm, through the wash water discharge opening 4 a, the washing water (tap water) _t disc supplied to the surface 2 a of the disc 2 at the 6 i min flow rate The cleaning water spraying power of the cleaning liquid sprayer 1 at a position 125 mm radially outward from the outer edge of 2 is applied to the bush to which the 50 mm x 85 mm acrylic plate 200 is attached. The bull gauge 300 was moved along a circular arc 125 mm away from the outer edge of the disk 2 in the radial direction to measure. The maximum injection power obtained by the measurement was 90 gf.

As shown in Fig. 5 (b), the diameter of the disks 11 and 12 of the cleaning liquid sprayer 10 is set to 130 mm, the thickness of the disks 11 and 12 is set to 3 mm, and The distance between 1 and 2 is 10 mm, and the dimensions of the wash water outlets 15a, 16a and 17a are 1 mm (circumferential) x 5 mm (radial). Washing water outlets 15a, 16a, 17a The radial distance from the central axis X2 of the discs 11, 12 is 55 mm, and the washing water outlet 15a, The distance from the surface 11a, llb, 12a, 12b of the disk 11a, 12a of 16a, 17a is 2mm, and the material of the disk 11, 12 is ABS. did. The disks 1 1 and 1 2 are driven to rotate at 800 rpm, and the disks 1 1 and 1 2 are rotated at a flow rate of 6 minutes through the washing water outlets 15 a, 16 a and 17 a. Cleaning water (tap water) was supplied to the surfaces 11a, lib, 12a, and 12b. The cleaning water spraying power of the cleaning liquid sprayer 10 at a position 1 25 mm radially outward from the outer edge of the disks 1 1 and 1 2 .50 mm X 85 mm acrylic plate 20 The measurement was carried out by moving the bush / pull gauge 300 with 0 attached thereto along an arc spaced from the outer edges of the disks 11 and 12 radially outward by 125 mm. The maximum injection power obtained by the measurement was 195 gf.

In the washing water injector 10 as well as the washing water injector 1, the motor 14 simply drives the disks 11 and 12 to rotate, and does not pressurize the washing water to a high pressure. Therefore, the motor 14 does not need to be as large as the motor for driving the pump of the conventional pressurized washing water injector. Accordingly, the washing water injector 10 is also smaller, like the washing water injector 1, as compared with the pressurized washing water injector of the prior art. Dishwashers with wash water jets 10 are smaller, have lower manufacturing and operating costs than prior art dishwashers with pressurized wash water jets, and are Low noise.

As with the washing water injector 1, it is not necessary to provide a pump, a high-pressure water injection nozzle, a water storage tank between the water supply pipe and the pump, etc. in the washing water injector 10 as well. As a result, the washing water injector 10, like the washing water injector 1, has a simpler structure than the conventional pressurized washing water injector. A dishwasher equipped with a washing water jet 10 is pressurized The structure is simpler than that of a conventional dishwasher equipped with a washing water jet, and the manufacturing cost and maintenance cost are low. Similarly, the cleaning water discharge ports 15a, 16a, and 17a of the cleaning water supply nozzles 15, 16, and 17 are moved radially outward from the center axis X2 of the disks 11 and 12. The cleaning water supplied to the discs 11 and 12 via the cleaning water discharge ports 15a, 16a and 17a From the relatively narrow circumferential area of the outer edges of the plates 11 and 12, the fuel is intensively spouted radially outward. A group of cleaning water droplets with large kinetic energy per unit volume can efficiently clean the object to be cleaned.

The washing water jetting power of the washing water jet 10 having two disks 11 and 12 is larger than that of the washing water jet 1 having one disk 2. Therefore, the washing water injector 10 can more efficiently wash the object to be washed as compared with the washing water injector 1.

(3) Third embodiment

In the washing water jet 20, as shown by the one-dot chain line in FIG. 7. The washing water supplied to the surface 21 a of the disk 21 has an arc shape at the outer edge of the surface 21 a. While flowing toward the surface 21b along the chamfered portion, it is dispersed little by little and spouts radially outward at high speed. As a result, the washing water supplied to the surface 21a of the disk 21 is broken into water droplets having a small particle diameter. On the other hand, the washing water supplied to the surface 21b of the disk 21 and the surface 22a and 22b of the disk 22 is distributed from the outer edge of the surface 21a, 22a and 22b. It gushes out at high speed radially outward without doing it. As a result, the washing water supplied to the surface 21b of the disk 21 and the surfaces 22a and 22b of the disk 22 are broken into water droplets having a large particle diameter. Therefore, in the washing water sprayer 20, the particle size of the ejected water droplets is changed by switching between water supply through the washing water supply nozzle 25 and hot water through the washing water supply nozzles 26, 27. can do.

Except for the above, the operation of the washing water injector 20 is the same as the operation of the washing water injector 10.

As shown in Fig. 8, the material of the disk 2 of the cleaning liquid sprayer 1 is ABS, the diameter of the disk 2 is 150 mm, the thickness of the disk 2 is 3 mm, and the cleaning water outlet 4 The dimension of a is 2 mm (circumferential direction) x 4 mm (radial direction), and the flush water discharge port 4 a is 60 mm in the radial direction from the center axis X 1 of the disc 2, and The outer edge of the surface 2a of the disk 2 was chamfered into an arc shape with a radius of 3 mm, and the washing water discharge port 5a was closed. The disk 2 was driven to rotate at 500 rpm, and the wash water (tap water) was supplied to the surface 2a of the disk 2 at a flow rate of 3.5 £ through the wash water discharge port 4a. The petri dish 400 coated with silicon oil was reciprocated along a circular arc 800 mm away from the outer edge of the disc 2 to collect water droplets ejected from the disc 2. Water droplets attached to the petri dish were photographed using a microscope, and the particle diameter of the water droplets was measured. The average particle size of the water droplets was 0.5 mm.

The particle size of water droplets ejected from the disk 2 was measured under the same conditions as above, except that the outer edge of the surface 2a of the disk 2 was not chamfered <the average particle size of the water droplets was 1.2. mm.
