Description

カビ抑制装置および水洗便器装置Mold control device and flush toilet device
　本発明は、水洗便器における貯留水の水面と便器内面との境界に生じる黒ずみの原因となるカビの発生を抑制するカビ抑制装置に関する。 BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a mold suppression device that suppresses the generation of mold that causes darkening that occurs at the boundary between the water surface of stored water and the inner surface of a toilet bowl in a flush toilet.
　水洗便器は、水を使用する都合上、カビ等が発生しやすい。このため、カビ等の発生を抑える種々の試みがなされている。 In the flush toilet bowl, molds and the like are easily generated because of the use of water. Therefore, various attempts have been made to suppress the occurrence of mold and the like.
　例えば、特許文献１には、人体の局部を乾燥するための温風をボウル部内の換気に利用することが記載されている。具体的には、検知したボウル部内の温度および湿度の少なくともいずれか一方が所定の閾値を超えると、上記の温風を発生させる。また、特許文献２には、水洗動作から所定の基準経過時間を超えたときに自動的に水洗動作を行うことが記載されている。 For example, Patent Document 1 describes that hot air for drying a local part of a human body is used to ventilate a bowl portion. Specifically, when at least one of the detected temperature and humidity in the bowl portion exceeds a predetermined threshold value, the above-described warm air is generated. Further, Patent Document 2 describes that the washing operation is automatically performed when the predetermined reference elapsed time from the washing operation is exceeded.
日本国公開特許公報「特開２００８－８１９２９号（２００８年４月１０日公開）」Japanese Patent Publication "Japanese Patent Application Publication No. 2008-81929 (Apr. 10, 2008)" 日本国公開特許公報「特開２００８－１３８３６５号（２００８年６月１９日公開）」Japanese patent publication "Japanese Patent Application Laid-Open No. 2008-138365 (June 19, 2008)"
　ところで、ボウル部における、貯留水の水面と接触する線状の部分（以降、水面線と称する）に、環状の黒ずみが発生することがある。このような黒ずみは、黒カビが原因となっていることが多く、一旦発生すると、除去することが困難である。 By the way, annular darkening may occur in a linear portion (hereinafter, referred to as a water surface line) in the bowl portion which is in contact with the water surface of stored water. Such darkening is often caused by black mold, and once it occurs it is difficult to remove.
　特許文献１に記載された技術では、ボウル部内の環境を整えることにより、カビ等の発生をある程度抑制することが可能である。しかしながら、黒カビは繁殖力が強く、水面線が一定位置にある状態が持続すると、黒カビの胞子が繁殖に好適な水分と酸素とを得やすくなる。 According to the technique described in Patent Document 1, it is possible to suppress the occurrence of mold and the like to some extent by adjusting the environment in the bowl portion. However, Aspergillus niger is highly fertile and when the water line is in a fixed position, spores of Aspergillus niger can easily obtain water and oxygen suitable for breeding.
　特許文献２に記載された技術では、水洗動作により、一部のカビ胞子を洗い流すことができるかもしれない。しかしながら、水洗動作が水面線付近のカビ胞子に水分を与えることとなり、却って黒カビの繁殖を促すことになる。 In the technique described in Patent Document 2, the washing operation may be able to wash away some mold spores. However, the water washing operation gives moisture to mold spores near the water surface line, and rather promotes the growth of black mold.
　このように、特許文献１，２に記載された技術では、環状の黒ずみを実質的に抑制することができなかった。 Thus, with the techniques described in Patent Documents 1 and 2, it was not possible to substantially suppress annular darkening.
　本発明の一態様は、環状の黒ずみの発生を抑制することを目的とする。 An object of the present invention is to suppress the occurrence of annular darkening.
　上記の課題を解決するために、本発明の一態様に係るカビ抑制装置は、水洗便器装置の便器本体に貯留された貯留水の水面を常時または断続的に変動させる水面変動部を備え、前記水洗便器装置に取り付けられる。 In order to solve the above-mentioned subject, the mold control device concerning one mode of the present invention is provided with the water level change part which changes the water surface of the storage water stored by the toilet bowl main part of flush toilet device constantly or intermittently. It is attached to the flush toilet bowl device.
　本発明の一態様によれば、環状の黒ずみの発生を抑制することができる。 According to one aspect of the present invention, the occurrence of annular darkening can be suppressed.

　図３および図４に示すように、イオン発生装置１は、カバー１１と、ファン１２と、部品実装部１３とを有している。部品実装部１３は、底板１４上に、イオン発生部１５、電源１６、コネクタ１７等が実装されることにより構成されている。 As shown in FIG. 3 and FIG. 4, the ion generator 1 has a cover 11, a fan 12 and a component mounting portion 13. The component mounting unit 13 is configured by mounting the ion generating unit 15, the power supply 16, the connector 17 and the like on the bottom plate 14.
　なお、以降の説明では、イオン発生装置１について、カバー１１側を上方と見なし、底板１４側を下方と見なす。 In the following description, the cover 11 side of the ion generator 1 is regarded as the upper side, and the bottom plate 14 side is regarded as the lower side.
　カバー１１は、ファン１２および部品実装部１３を覆う部材であり、長方形を成す天板１１ａと、当該天板１１ａの四方を囲む側板１１ｂ～１１ｅとで構成されている。側板１１ｂ，１１ｃ，１１ｅの幅が狭く形成されることにより、イオン発生装置１が薄型に構成される。イオン発生装置１の大きさは、例えば、幅３５ｍｍ×長さ６０ｍｍ×厚さ１０ｍｍ程度である。 The cover 11 is a member that covers the fan 12 and the component mounting portion 13, and is configured of a rectangular top plate 11a and side plates 11b to 11e that surround four sides of the top plate 11a. By forming the side plates 11b, 11c, and 11e to be narrow, the ion generator 1 is configured to be thin. The size of the ion generator 1 is, for example, about 35 mm wide × 60 mm long × 10 mm thick.
　カバー１１（イオン発生装置１）は、天板１１ａを有することにより、天板１１ａで便蓋４の裏面に取り付け可能に構成されている。例えば、天板１１ａにネジ孔（図示せず）が設けられることにより、当該ネジ孔に通されたネジを便蓋４に設けられた雌ネジ部（図示せず）に締め付けることにより、カバー１１を便蓋４に結合させる。あるいは、天板１１ａの外面に粘着性の材料（接着剤、両面テープ等）を付与しておき、カバー１１を天板１１ａにおいて便蓋４の裏面に接着結合させる。 The cover 11 (ion generator 1) is configured to be attachable to the back surface of the toilet lid 4 with the top plate 11a by having the top plate 11a. For example, by providing a screw hole (not shown) in the top plate 11a, the cover 11 is tightened by fastening a screw passed through the screw hole to a female screw portion (not shown) provided in the toilet lid 4. Is attached to the toilet lid 4. Alternatively, an adhesive material (adhesive, double-sided tape or the like) is applied to the outer surface of the top plate 11a, and the cover 11 is adhesively bonded to the back surface of the toilet lid 4 at the top plate 11a.
　天板１１ａの長辺側の２つの側板１１ｂ，１１ｃのうちの側板１１ｂには、外気をイオン発生装置１の内部に吸い込むための吸込口１１ｆが形成されている。吸込口１１ｆは、側板１１ｂの長手方向に伸びるスリット状に形成されている。また、天板１１ａの短辺側の２つの側板１１ｄ，１１ｅのうちの側板１１ｄは、湾曲する形状を成すように形成されている。 A suction port 11 f for sucking outside air into the ion generator 1 is formed on the side plate 11 b of the two side plates 11 b and 11 c on the long side of the top 11 a. The suction port 11 f is formed in a slit shape extending in the longitudinal direction of the side plate 11 b. The side plate 11d of the two side plates 11d and 11e on the short side of the top plate 11a is formed to have a curved shape.
　底板１４は、天板１１ａと同じ形状（長方形）かつ同じ大きさに形成されている。カバー１１の開放された部分が、天板１１ａと対向するように配置された底板１４で塞がれることにより、箱状の筐体が形成される。また、側板１１ｄ側に位置する底板１４の端部と、側板１１ｄとにより、下方に開口する吹出口１０が形成されている。吹出口１０は、吸込口１１ｆから吸い込まれた外気をイオン発生装置１の外部に吹き出すための開口である。 The bottom plate 14 is formed in the same shape (rectangle) and the same size as the top plate 11 a. A box-like housing is formed by closing the open portion of the cover 11 with the bottom plate 14 disposed to face the top plate 11 a. Moreover, the blower outlet 10 opened below is formed of the edge part of the bottom plate 14 located in the side plate 11 d side, and the side plate 11 d. The blowout port 10 is an opening for blowing out the outside air sucked from the suction port 11 f to the outside of the ion generator 1.
　ファン１２は、外気を吸い込むための吸引力を発生する部品であり、薄型の遠心ファン、プロペラファン等が用いられる。ファン１２は、部品実装部１３上の吸込口１１ｆより下方に配置されるとともに、カバー１１の天板１１ａに対向する側から吸気するように配置されている。また、ファン１２は側板１１ｄ側に排気する。 The fan 12 is a component that generates a suction force for sucking in the outside air, and a thin centrifugal fan, a propeller fan or the like is used. The fan 12 is disposed below the suction port 11 f on the component mounting portion 13, and is disposed so as to take in air from the side of the cover 11 facing the top plate 11 a. Also, the fan 12 exhausts to the side plate 11 d side.
　イオン発生部１５は、電源１６から供給される電力により正イオンおよび負イオンを発生させる。イオン発生部１５は、底板１４上の一端側（側板１１ｄ側）に配置されている。イオン発生部１５は、正電極１５１と、負電極１５２と、トランス１５３と、トランス駆動回路１５４と、基板１５５と、絶縁カバー１５６とを有している。正電極１５１、負電極１５２、トランス１５３およびトランス駆動回路１５４は、基板１５５上に実装されている。基板１５５上には、正電極１５１に対応する誘導電極（図示せず）と、負電極１５２に対応する誘導電極（図示せず）が形成されている。 The ion generation unit 15 generates positive ions and negative ions by the power supplied from the power supply 16. The ion generating unit 15 is disposed on one end side (side plate 11 d side) on the bottom plate 14. The ion generation unit 15 includes a positive electrode 151, a negative electrode 152, a transformer 153, a transformer drive circuit 154, a substrate 155, and an insulating cover 156. The positive electrode 151, the negative electrode 152, the transformer 153, and the transformer drive circuit 154 are mounted on the substrate 155. An induction electrode (not shown) corresponding to the positive electrode 151 and an induction electrode (not shown) corresponding to the negative electrode 152 are formed on the substrate 155.
　正電極１５１、負電極１５２は、底板１４の一端側（カバー１１の側板１１ｄ側）に間隔をおいて配置されている。また、トランス１５３は、正電極１５１および負電極１５２よりも、底板１４の他端側寄りに配置されている。さらに、トランス駆動回路１５４は、トランス１５３よりもさらに底板１４の他端側寄りに配置されている。正電極１５１および負電極１５２の一部と、トランス１５３とは絶縁カバー１５６によって覆われている。正電極１５１および負電極１５２の先端は、絶縁カバー１５６から露出している。 The positive electrode 151 and the negative electrode 152 are arranged at intervals on one end side of the bottom plate 14 (side plate 11 d side of the cover 11). In addition, the transformer 153 is disposed closer to the other end side of the bottom plate 14 than the positive electrode 151 and the negative electrode 152. Furthermore, the transformer drive circuit 154 is disposed closer to the other end side of the bottom plate 14 than the transformer 153. The positive electrode 151 and a part of the negative electrode 152 and the transformer 153 are covered by an insulating cover 156. The tips of the positive electrode 151 and the negative electrode 152 are exposed from the insulating cover 156.
　電源１６は、コネクタ１７を介して外部から供給される電力を、ファン１２およびイオン発生部１５に適した形態に変換してファン１２およびイオン発生部１５のそれぞれに供給する。 The power supply 16 converts the power supplied from the outside through the connector 17 into a form suitable for the fan 12 and the ion generating unit 15 and supplies the converted power to the fan 12 and the ion generating unit 15 respectively.
　コネクタ１７は、外部からケーブル（図示せず）を介して供給される電力を受ける接続端子である。コネクタ１７は、ケーブルの先端に設けられたコネクタ（図示せず）と接続されるように構成されている。 The connector 17 is a connection terminal for receiving power supplied from the outside via a cable (not shown). The connector 17 is configured to be connected to a connector (not shown) provided at the end of the cable.
　上記のように構成されるイオン発生装置１において、トランス１５３が、トランス駆動回路１５４に駆動されることによって一次側の電圧を昇圧して二次側に出力する。正電極１５１は、昇圧された正電圧が印加されることで、対応する誘導電極との間でコロナ放電を生じて、正イオンを発生する。負電極１５２は、昇圧された負電圧が印加されることで、対応する誘導電極との間でコロナ放電を生じて、負イオンを発生する。 In the ion generator 1 configured as described above, the transformer 153 is driven by the transformer drive circuit 154 to boost the voltage on the primary side and output it to the secondary side. The positive electrode 151 generates corona discharge with the corresponding induction electrode by applying a boosted positive voltage to generate positive ions. The negative electrode 152 receives a boosted negative voltage to cause corona discharge with the corresponding induction electrode to generate negative ions.
　ファン１２は、吸込口１１ｆから取り込んだ空気を吸い込んで排出する。上記のようにして発生した正イオンおよび負イオンは、ファン１２の動作によって生じた空気の流れによって、吹出口１０から外部に吹き出される。カバー１１および底板１４によって構成される空気の通路と、空気の流れを発生するファン１２とによって、貯水部２１ａに蓄えられた水の水面に向けて風を送り出す送風機構（水面変動部）が構成される。また、当該送風機構と、イオン発生部１５とで、上記水面にイオンを供給するイオン供給部が構成される。 The fan 12 sucks in and discharges the air taken in from the suction port 11 f. The positive ions and negative ions generated as described above are blown out from the outlet 10 by the flow of air generated by the operation of the fan 12. A blower mechanism (water surface fluctuating part) configured to send wind toward the water surface of the water stored in the water storage part 21a by the air passage constituted by the cover 11 and the bottom plate 14 and the fan 12 generating the air flow is constituted. Be done. In addition, an ion supply unit that supplies ions to the water surface is configured by the air blowing mechanism and the ion generation unit 15.
　続いて、水洗便器装置１００の制御系について説明する。図５は、水洗便器装置１００のシステム構成を示すブロック図である。 Subsequently, a control system of the flush toilet device 100 will be described. FIG. 5 is a block diagram showing a system configuration of the flush toilet device 100. As shown in FIG.
　図５に示すように、水洗便器装置１００は、イオン発生装置１と、制御部３１と、開閉センサ３２とを有している。 As shown in FIG. 5, the flush toilet device 100 has an ion generator 1, a control unit 31, and an open / close sensor 32.
　開閉センサ３２は、便蓋４の開状態と閉状態とを検知する検知器である。開閉センサ３２には、機械式のセンサ、光学式のセンサ等が用いられる。 The open / close sensor 32 is a detector that detects the open state and the closed state of the toilet lid 4. As the open / close sensor 32, a mechanical sensor, an optical sensor or the like is used.
　機械式のセンサは、例えば、閉じた状態の便蓋４の内面に当接する接触部材を有している。当該センサは、接触部材が閉じた便蓋４によって押し込まれてＯＮすることで閉状態を検知する一方、接触部材が便蓋４の開いた状態で開放されてＯＦＦすることで開状態を検知する。機械式のセンサは、便蓋４の開閉部位の付近に配置されている。 The mechanical sensor has, for example, a contact member that abuts on the inner surface of the toilet lid 4 in the closed state. The sensor detects the closed state by being pushed in and turned on by the toilet lid 4 in which the contact member is closed, and detects the open state by the contact member being opened and turned off in the opened state of the toilet lid 4 . The mechanical sensor is disposed near the opening / closing portion of the toilet lid 4.
　光学式のセンサは、例えば、発光部と、受光部とを有している。受光部は、発光部の出射光が便蓋４の裏面に反射した反射光を受光する位置に配置される。当該センサは、発光部からの出射光が閉じた便蓋４によって反射した反射光を受光すると閉状態を検知する一方、反射光を受光しないと開状態を検知する。光学式のセンサは、便蓋４の開閉部位の付近に配置されている。 The optical sensor includes, for example, a light emitting unit and a light receiving unit. The light receiving unit is disposed at a position where the light emitted from the light emitting unit receives the reflected light reflected by the back surface of the toilet lid 4. The sensor detects the closed state when receiving the reflected light reflected by the toilet lid 4 from which the light emitted from the light emitting unit is closed, and detects the open state when the reflected light is not received. The optical sensor is disposed near the opening / closing portion of the toilet lid 4.
　制御部３１は、開閉センサ３２からの検知信号に応じてイオン発生装置１への電力供給を制御する。具体的には、制御部３１は、開閉センサ３２から便蓋４の閉状態を検知する閉検知信号を受けると、イオン発生装置１への電力を供給する一方、開閉センサ３２から便蓋４の開状態を検知する開検知信号を受けると、イオン発生装置１への電力供給を停止する。 The control unit 31 controls the power supply to the ion generator 1 in accordance with the detection signal from the open / close sensor 32. Specifically, when the control unit 31 receives a close detection signal for detecting the closed state of the toilet lid 4 from the open / close sensor 32, the control unit 31 supplies power to the ion generating device 1 while When the open detection signal for detecting the open state is received, the power supply to the ion generator 1 is stopped.
　制御部３１は、集積回路（ＩＣチップ）等に形成された論理回路（ハードウェア）によって実現されてもよいし、ＣＰＵ（Central Processing Unit）を用いてソフトウェアによって実現されてもよい。 The control unit 31 may be realized by a logic circuit (hardware) formed in an integrated circuit (IC chip) or the like, or may be realized by software using a CPU (Central Processing Unit).
　引き続き、上記のように構成される水洗便器装置１００によるイオン発生装置１の動作を説明する。 Subsequently, the operation of the ion generating device 1 by the flush toilet device 100 configured as described above will be described.
　ここで、水洗便器装置１００が使用されていない状態では、便座３が下げられており、かつ便蓋４が閉じているものとする。この状態で、制御部３１は、開閉センサ３２からの閉検知信号を受けて、イオン発生装置１に電力を供給する。これにより、イオン発生装置１は、イオン発生部１５によって発生したイオンを、ファン１２が発生した風によって、図２に示すように、吹出口１０から下方に向けて放出する。 Here, it is assumed that the toilet seat 3 is lowered and the toilet lid 4 is closed when the flush toilet device 100 is not in use. In this state, the control unit 31 receives the close detection signal from the open / close sensor 32 and supplies power to the ion generator 1. Thereby, the ion generator 1 discharges the ion which generate | occur | produced by the ion generation part 15 toward the downward direction from the blower outlet 10 by the wind which the fan 12 generate | occur | produced, as shown in FIG.
　放出されたイオンは、便器本体のボウル部２１の貯水部２１ａに貯留された水の水面に吹きつけられると、水面上を拡散してボウル部２１の全体に広がっていく。また、イオン発生装置１の吹出口１０から送出される風によって、水面には微小な振動が生じる。 When the released ions are blown to the water surface of the water stored in the water storage portion 21 a of the bowl portion 21 of the toilet bowl main body, the ions spread on the water surface and spread throughout the bowl portion 21. In addition, a minute vibration is generated on the water surface by the wind sent from the blowout port 10 of the ion generator 1.
　水洗便器装置１００が使用される状態では、便蓋４が開かれる。この状態で、制御部３１は、開閉センサ３２からの開検知信号を受けて、イオン発生装置１への電力供給を停止する。これにより、イオン発生装置１は動作を停止する。 When the flush toilet device 100 is in use, the toilet lid 4 is opened. In this state, the control unit 31 receives the open detection signal from the open / close sensor 32 and stops the power supply to the ion generator 1. Thereby, the ion generator 1 stops operation.
　このように、本実施形態の水洗便器装置１００は、イオン発生装置１を備えている。これにより、イオン発生装置１が動作している間には、イオン発生装置１（カバー１１、ファン１２および底板１４から成る送風機構）からの風により、貯留水の蒸発が促される。それゆえ、貯留水の水面が低下し続けることで、水洗動作などの一時的な期間を除いて、水面を常時変動させることができる。したがって、ボウル部２１における貯留水の水面と接触する線状の部分である水面線が一定位置に留まることはない。 As described above, the flush toilet bowl apparatus 100 of the present embodiment includes the ion generator 1. Thus, while the ion generating device 1 is in operation, the wind from the ion generating device 1 (the air blowing mechanism including the cover 11, the fan 12 and the bottom plate 14) promotes the evaporation of the stored water. Therefore, the water surface can be constantly fluctuated except for a temporary period such as the flush operation because the water surface of the stored water continues to decrease. Therefore, the water surface line, which is a linear portion in contact with the water surface of the stored water in the bowl portion 21, does not stay at a fixed position.
　黒ずみの主な要因となる黒カビは、胞子の段階では、胞子の殻を破って白い菌糸を出して広がっていく。菌糸は、乾燥に弱く、乾燥状態が３時間程度持続することで死滅する。それゆえ、上記のように水面が低下し続けることにより、ボウル部２１に付着している菌糸を死滅させることができる。したがって、黒ずみの発生を抑制することができる。 Black mold, which is the main cause of darkening, breaks the shell of spore and spreads out white hyphae at the spore stage. Mycelia are weak to dryness and die when the dryness lasts for about 3 hours. Therefore, by continuously reducing the water surface as described above, it is possible to kill the mycelium adhering to the bowl portion 21. Therefore, the occurrence of darkening can be suppressed.
　なお、水洗動作によってボウル部２１表面に水が流されることで、菌糸に一時的に水分が供給される。これに対し、水洗動作の間隔が３時間を超える時間帯（例えば深夜）があればよく、この時間帯では菌糸への水分が完全に断たれる。 In addition, water is temporarily supplied to the mycelium by flowing water on the surface of the bowl portion 21 by the washing operation. On the other hand, it is sufficient if there is a time zone (for example, midnight) in which the interval of the washing operation exceeds 3 hours, and the water to the mycelium is completely cut off in this time zone.
　また、イオン発生装置１からの風が貯留水の水面を振動させることよっても、黒カビの繁殖を抑えることができる。仮に上記のような水位の低下がなかったとしても、水面が振動することにより、水面線が一定位置に留まることがない。これにより、カビ胞子への酸素供給が持続的に行われなくなるので、黒カビの繁殖を抑えることができる。水面へ振動を付与する手段としては、送風に限らず、機械的な振動をボウル部２１の表面に与える機械的振動部、超音波を水面に放射する照射する超音波放射部などを設けてもよい。 In addition, the generation of black mold can also be suppressed by the fact that the wind from the ion generator 1 vibrates the surface of the stored water. Even if the water level does not drop as described above, the water surface will not stay at a constant position due to the vibration of the water surface. Thereby, since oxygen supply to mold spores is not continuously performed, the growth of black mold can be suppressed. As means for applying vibration to the water surface, not only air but also a mechanical vibration unit which applies mechanical vibration to the surface of the bowl portion 21 and an ultrasonic wave radiation unit which irradiates ultrasonic waves to the water surface are provided. Good.
　また、イオン発生装置１からの送風のみでも、上記のように、黒ずみの発生を十分抑制することができるが、イオン発生装置１から供給されるイオンによっても、黒カビの繁殖が抑制される。それゆえ、環状の黒ずみを抑制する効果をより一層高めることができる。 Moreover, although generation | occurrence | production of darkening can be sufficiently suppressed as mentioned above only by the ventilation from the ion generator 1, the reproduction of black mold is also suppressed by the ion supplied from the ion generator 1. Therefore, the effect of suppressing annular darkening can be further enhanced.
　また、水洗便器装置１００は、便蓋４にイオン発生装置１を取り付ける構造を採用している。これにより、便器本体２および便座３が、イオン発生装置１を設けるための特別な形状を有することなく、簡易な構造でイオン発生装置１を設けることができる。 Further, the flush toilet device 100 adopts a structure in which the ion generator 1 is attached to the toilet lid 4. As a result, the toilet body 2 and the toilet seat 3 can be provided with the ion generating device 1 with a simple structure without having a special shape for providing the ion generating device 1.
　なお、イオン発生装置１は、断続的に水面を変動させるように、適当な時間間隔をおいて、断続的に送風およびイオンの発生を行ってもよい。また、イオン発生装置１は、常時または断続的に水面を変動させることを適宜設定可能である。 The ion generator 1 may intermittently generate air and generate ions at appropriate time intervals so as to change the water surface intermittently. Moreover, the ion generator 1 can be suitably set to fluctuate the water surface constantly or intermittently.
　〔実施形態２〕
　本発明の実施形態２について、図２、図３、図４および図６に基づいて説明すれば、以下に通りである。 Second Embodiment
It will be as follows if Embodiment 2 of this invention is demonstrated based on FIG.2, FIG.3, FIG.4 and FIG.
　なお、説明の便宜上、実施形態１にて説明した構成要素と同じ機能を有する構成要素については、同じ符号を付記し、その説明を繰り返さない。 Note that, for convenience of explanation, the same reference numerals are appended to components having the same functions as the components described in the first embodiment, and the description will not be repeated.
　図６は、実施形態２に係る水洗便器装置１００の制御系の構成を示すブロック図である。 FIG. 6 is a block diagram showing a configuration of a control system of the flush toilet bowl apparatus 100 according to the second embodiment.
　図２に示す水洗便器装置１００は、実施形態１の水洗便器装置１００におけるイオン発生装置１に変えてイオン発生装置１Ａ（カビ抑制装置）を備えている。イオン発生装置１Ａは、図３および図４に示すように、イオン発生装置１と同じに構成されている。なお、本実施形態の水洗便器装置１００は便蓋４を備えていなくてもよい。 The water closet device 100 shown in FIG. 2 is provided with an ion generation device 1A (mold suppression device) in place of the ion generation device 1 in the water closet device 100 of the first embodiment. The ion generator 1A is configured the same as the ion generator 1 as shown in FIG. 3 and FIG. The flush toilet apparatus 100 according to the present embodiment may not have the toilet lid 4.
　イオン発生装置１Ａは、便座３の後部に内蔵されている。また、便座３には、イオン発生装置１Ａの吹出口１０から吹き出されたイオンを含む風を通すための貫通孔３ａが設けられている。イオン発生装置１Ａは、便座３の内面（内底面）に取り付け可能に構成されている。例えば、底板１４にネジ孔（図示せず）が設けられることにより、当該ネジ孔に通されたネジを便座３に設けられた雌ネジ部（図示せず）に締め付けることにより、底板１４を便座３に結合させる。あるいは、底板１４の外面に粘着性の材料（接着剤、両面テープ等）を付与しておき、底板１４において便座３の内面に接着結合させる。このような底板１４による取り付けを可能とするために、便座３は、上限に分割可能に形成されている。 The ion generator 1 </ b> A is built in the rear of the toilet seat 3. Moreover, the through-hole 3a for letting the wind containing the ion which blew off from the blower outlet 10 of 1 A of ion generators is provided in the toilet seat 3. As shown in FIG. The ion generator 1A is configured to be attachable to the inner surface (inner bottom surface) of the toilet seat 3. For example, by providing a screw hole (not shown) in the bottom plate 14, the bottom plate 14 is closed by tightening the screw passed through the screw hole to an internal thread portion (not shown) provided in the toilet seat 3. Bond to 3. Alternatively, an adhesive material (adhesive, double-sided tape or the like) is applied to the outer surface of the bottom plate 14 and adhesively bonded to the inner surface of the toilet seat 3 at the bottom plate 14. In order to enable such attachment by the bottom plate 14, the toilet seat 3 is formed to be divisible to the upper limit.
　また、図６に示すように、本実施形態の水洗便器装置１００は、制御部４１と、イオン発生装置１Ａと、制御部４１と、着座センサ４２と、上下センサ４３とを有している。 Further, as shown in FIG. 6, the flush toilet device 100 of the present embodiment has a control unit 41, an ion generator 1A, a control unit 41, a seating sensor 42, and an upper and lower sensor 43.
　着座センサ４２は、便座３上に使用者が着座していることを検知する検知器である。着座センサ４２には、例えば圧力センサ等が用いられる。圧力センサは、便座３における、使用者の着座によって最も大きく変形する部位の内部に設けられ、当該変形を捉えることで着座を検知する。 The seating sensor 42 is a detector that detects that the user is seated on the toilet seat 3. For example, a pressure sensor or the like is used as the seating sensor 42. The pressure sensor is provided inside the portion of the toilet seat 3 that is most greatly deformed by the seating of the user, and detects the seating by capturing the deformation.
　上下センサ４３は、便座３の上げられた状態（開状態）と下げられた状態（閉状態）とを検知する検知器である。開閉センサ３２には、実施形態１における開閉センサ３２と同じく、機械式のセンサ、光学式のセンサ等が用いられる。 The upper and lower sensors 43 are detectors that detect the raised state (open state) and the lowered state (closed state) of the toilet seat 3. As the open / close sensor 32 in the first embodiment, a mechanical sensor, an optical sensor, or the like is used as the open / close sensor 32.
　制御部４１は、着座センサ４２および上下センサ４３からの検知信号に応じてイオン発生装置１Ａへの電力供給を制御する。具体的には、制御部４１は、着座センサ４２から便座３への非着座状態を検知する非着座検知信号を受けると、イオン発生装置１Ａへの電力を供給する。一方、制御部４１は、着座センサ４２から便座３への着座状態を検知する着座検知信号を受けると、イオン発生装置１Ａへの電力供給を停止する。また、制御部４１は、上下センサ４３から便座３の下げ状態を検知する下げ検知信号を受けると、イオン発生装置１Ａへの電力を供給する。一方、制御部４１は、上下センサ４３から便座３の上げ状態を検知する上げ検知信号を受けると、イオン発生装置１への電力供給を停止する。 The control unit 41 controls the power supply to the ion generator 1A according to the detection signals from the seating sensor 42 and the upper and lower sensors 43. Specifically, upon receiving a non-seating detection signal for detecting a non-seating state on the toilet seat 3 from the seating sensor 42, the control unit 41 supplies power to the ion generator 1A. On the other hand, when the control unit 41 receives from the seating sensor 42 a seating detection signal for detecting a seating state on the toilet seat 3, the control unit 41 stops the power supply to the ion generator 1A. Further, when the control unit 41 receives a lowering detection signal for detecting the lowering state of the toilet seat 3 from the upper and lower sensors 43, it supplies power to the ion generator 1A. On the other hand, when the control unit 41 receives from the upper and lower sensors 43 a rise detection signal for detecting the raised state of the toilet seat 3, the control unit 41 stops the power supply to the ion generator 1.
　制御部４１は、集積回路（ＩＣチップ）等に形成された論理回路（ハードウェア）によって実現されてもよいし、ＣＰＵ（Central Processing Unit）を用いてソフトウェアによって実現されてもよい。 The control unit 41 may be realized by a logic circuit (hardware) formed in an integrated circuit (IC chip) or the like, or may be realized by software using a CPU (Central Processing Unit).
　続いて、上記のように構成される水洗便器装置１００によるイオン発生装置１Ａの動作を説明する。 Subsequently, the operation of the ion generator 1A by the flush toilet device 100 configured as described above will be described.
　ここで、水洗便器装置１００が使用されていない状態では、便座３が下げられているものとする。この状態で、制御部４１は、着座センサ４２からの非着座検知信号と上下センサ４３からの下げ検知信号とを受けて、イオン発生装置１Ａに電力を供給する。これにより、イオン発生装置１Ａは、イオン発生部１５によって発生したイオンを、ファン１２が発生した風によって下方に向けて放出する。 Here, it is assumed that the toilet seat 3 is lowered when the flush toilet device 100 is not in use. In this state, the control unit 41 receives the non-seating detection signal from the seating sensor 42 and the lowering detection signal from the upper and lower sensors 43, and supplies power to the ion generator 1A. Thereby, the ion generator 1A discharges the ions generated by the ion generator 15 downward by the wind generated by the fan 12.
　水洗便器装置１００が小便器として使用される状態では、便座３が上げられる。この状態で、制御部４１は、着座センサ４２からの非着座検知信号および上下センサ４３からの上げ検知信号を受けて、イオン発生装置１Ａへの電力供給を停止する。これにより、イオン発生装置１Ａは動作を停止する。 When the flush toilet device 100 is used as a urinal, the toilet seat 3 is raised. In this state, the control unit 41 receives the non-seating detection signal from the seating sensor 42 and the raising detection signal from the upper and lower sensors 43, and stops the power supply to the ion generator 1A. Thereby, the ion generator 1A stops its operation.
　水洗便器装置１００が着座使用される状態では、便座３が下げられる。この状態で、制御部４１は、上下センサ４３からの下げ検知信号を受けてはいるが、着座センサ４２からの着座検知信号を優先して受け入れることにより、イオン発生装置１Ａへの電力供給を停止する。これにより、イオン発生装置１Ａは動作を停止する。 When the flush toilet device 100 is seated and used, the toilet seat 3 is lowered. In this state, the control unit 41 receives the lowering detection signal from the upper and lower sensor 43, but stops the power supply to the ion generator 1A by preferentially receiving the seating detection signal from the seating sensor 42. Do. Thereby, the ion generator 1A stops its operation.
　このように、本実施形態の水洗便器装置１００は、イオン発生装置１Ａを備えることにより、イオン発生装置１Ａが動作している間には、イオン発生装置１Ａからの風により、貯留水の蒸発が促される。これにより、貯留水の水面が低下し続ける。それゆえ、ボウル部２１における貯留水の水面と接触する線状の部分である水面線が一定位置に留まることはない。したがって、上記のように水面が低下し続けることにより、ボウル部２１に付着している菌糸を死滅させることができる。よって、黒ずみの発生を抑制することができる。 As described above, the flush toilet apparatus 100 according to the present embodiment includes the ion generating apparatus 1A, and while the ion generating apparatus 1A is in operation, evaporation of stored water is caused by the wind from the ion generating apparatus 1A. Prompted. As a result, the surface of the stored water continues to decline. Therefore, the water surface line, which is a linear portion in contact with the water surface of the stored water in the bowl portion 21, does not stay in a fixed position. Therefore, the hyphae adhering to the bowl part 21 can be killed by the water surface continuing to fall as mentioned above. Thus, the occurrence of darkening can be suppressed.
　また、イオン発生装置１Ａが便座３に設けられることにより、便蓋４の有無および便蓋４の開閉に関わらず、イオン発生装置１Ａの動作を制御することができる。 Further, by providing the ion generator 1A on the toilet seat 3, the operation of the ion generator 1A can be controlled regardless of the presence or absence of the toilet lid 4 and the opening and closing of the toilet lid 4.
　なお、上述の本実施形態では、便座３への着座状態においてイオン発生装置１Ａの動作を停止させている。しかしながら、イオン発生装置１Ａが発生するイオンは人体に無害であり、かつイオン発生装置１Ａが発生する風は微風であるため、着座状態であっても、イオン発生装置１Ａを動作させてもよい。この場合は、着座センサ４２を省略することができる。 In the above-described embodiment, the operation of the ion generating device 1A is stopped in the sitting state on the toilet seat 3. However, since the ions generated by the ion generator 1A are harmless to the human body and the wind generated by the ion generator 1A is a slight wind, the ion generator 1A may be operated even in the sitting state. In this case, the seating sensor 42 can be omitted.
　また、イオン発生装置１Ａは、断続的に水面を変動させるように、適当な時間間隔をおいて、断続的に送風およびイオンの発生を行ってもよい。また、イオン発生装置１Ａは、常時または断続的に水面を変動させることを適宜設定可能である。 In addition, the ion generator 1A may intermittently generate air and generate ions at appropriate time intervals so as to intermittently change the water surface. Moreover, 1 A of ion generators can be suitably set to fluctuate a water surface regularly or intermittently.
　〔実施形態３〕

It will be as follows if Embodiment 3 of this invention is demonstrated based on FIG.2, FIG3 and FIG.4. Note that, for convenience of explanation, the same reference numerals are appended to components having the same functions as the components described in the first and second embodiments, and the description thereof is omitted.
　図２に示す水洗便器装置１００は、実施形態１の水洗便器装置１００におけるイオン発生装置１に変えてイオン発生装置１Ｂ（カビ抑制装置）を備えている。イオン発生装置１Ｂは、図３および図４に示すように、イオン発生装置１と同じに構成されている。なお、本実施形態の水洗便器装置１００は便蓋４を備えていなくてもよい。 The flush toilet apparatus 100 shown in FIG. 2 is provided with an ion generator 1 B (mold suppression apparatus) instead of the ion generator 1 in the flush toilet apparatus 100 of the first embodiment. As shown in FIGS. 3 and 4, the ion generator 1 </ b> B is configured the same as the ion generator 1. The flush toilet apparatus 100 according to the present embodiment may not have the toilet lid 4.
　便器本体２の上端部における後部の開口部２４周辺には、浅い凹部２４ａが開口部２４に通じるように形成されている。イオン発生装置１Ｂは、吹出口１０を含む端部を開口部２４内に突出するように、凹部２４ａに配置されている。イオン発生装置１Ｂは、凹部２４ａに取り付け可能に構成されている。例えば、底板１４にネジ孔（図示せず）が設けられることにより、当該ネジ孔に通されたネジを凹部２４ａに設けられた雌ネジ部（図示せず）に締め付けることにより、底板１４を凹部２４ａに結合させる。あるいは、底板１４の外面に粘着性の材料（接着剤、両面テープ等）を付与しておき、底板１４において凹部２４ａに接着結合させる。 A shallow recess 24 a is formed around the rear opening 24 at the upper end of the toilet body 2 so as to communicate with the opening 24. The ion generator 1 B is disposed in the recess 24 a so that the end including the outlet 10 protrudes into the opening 24. The ion generator 1B is configured to be attachable to the recess 24a. For example, when the bottom plate 14 is provided with a screw hole (not shown), the bottom plate 14 is recessed by tightening a screw passed through the screw hole in a female screw (not shown) provided in the recess 24a. Bond to 24a. Alternatively, an adhesive material (adhesive, double-sided tape or the like) is applied to the outer surface of the bottom plate 14 and adhesively bonded to the recess 24 a in the bottom plate 14.
　続いて、上記のように構成される水洗便器装置１００によるイオン発生装置１Ｂの動作を説明する。 Subsequently, the operation of the ion generator 1B by the flush toilet apparatus 100 configured as described above will be described.
　イオン発生装置１Ｂは、水洗便器装置１００が使用されていない状態および使用されている状態に関わらず、常時動作している。この状態で、イオン発生装置１Ｂは、イオン発生部１５によって発生したイオンを、ファン１２が発生した風によって下方に向けて放出する。 The ion generator 1B is always in operation regardless of whether the flush toilet device 100 is not in use or in use. In this state, the ion generator 1B discharges the ions generated by the ion generator 15 downward by the wind generated by the fan 12.
　このように、本実施形態の水洗便器装置１００は、イオン発生装置１Ｂを備えることにより、イオン発生装置１Ｂが動作している間には、イオン発生装置１Ｂからの風により、貯留水の蒸発が促される。これにより、貯留水の水面が低下し続ける。それゆえ、ボウル部２１における貯留水の水面と接触する線状の部分である水面線が一定位置に留まることはない。したがって、上記のように水面が低下し続けることにより、ボウル部２１に付着している菌糸を死滅させることができる。よって、黒ずみの発生を抑制することができる。 As described above, the flush toilet apparatus 100 according to the present embodiment includes the ion generator 1B, so that the stored water is evaporated by the wind from the ion generator 1B while the ion generator 1B is operating. Prompted. As a result, the surface of the stored water continues to decline. Therefore, the water surface line, which is a linear portion in contact with the water surface of the stored water in the bowl portion 21, does not stay in a fixed position. Therefore, the hyphae adhering to the bowl part 21 can be killed by the water surface continuing to fall as mentioned above. Thus, the occurrence of darkening can be suppressed.
　また、イオン発生装置１Ｂが便器本体２に設けられることにより、便蓋４の有無、便蓋４の開閉および便座３の上げ下ろしに関わらず、イオン発生装置１Ｂを常時動作させることができる。これにより、実施形態１および２で用いる制御部３１，４１および各種センサを省略することができる。 Further, by providing the ion generator 1B on the toilet body 2, the ion generator 1B can be operated at all times regardless of the presence or absence of the toilet lid 4, the opening and closing of the toilet lid 4, and the lifting and lowering of the toilet seat 3. As a result, the control units 31 and 41 and various sensors used in the first and second embodiments can be omitted.
　なお、イオン発生装置１Ｂは、断続的に水面を変動させるように、適当な時間間隔をおいて、断続的に送風およびイオンの発生を行ってもよい。また、イオン発生装置１Ｂは、常時または断続的に水面を変動させることを適宜設定可能である。 The ion generator 1B may intermittently generate air and generate ions at appropriate time intervals so as to intermittently change the water surface. Moreover, the ion generator 1B can be suitably set to fluctuate the water surface constantly or intermittently.
　〔実施形態４〕
　本発明の実施形態４について、図７に基づいて説明すれば、以下のとおりである。なお、説明の便宜上、実施形態１および２にて説明した構成要素と同等の機能を有する構成要素については、同じ符号を付記し、その説明を省略する。 Embodiment 4
It will be as follows if Embodiment 4 of this invention is demonstrated based on FIG. Note that, for convenience of explanation, the same reference numerals are appended to components having the same functions as the components described in the first and second embodiments, and the description thereof is omitted.
　本実施形態では、実施形態１および２で説明した黒ずみの抑制効果を検証するための試験について説明する。 In this embodiment, a test for verifying the suppression effect of the darkening described in Embodiments 1 and 2 will be described.
　図７の（ａ）～（ｅ）は擬似便器に貯留された水にイオンを送風にて供給した状態の推移を示す写真であり、（ｆ）～（ｊ）は擬似便器に貯留された水にイオンを送風にて供給しなかった状態の推移を示す写真である。 (A) to (e) of FIG. 7 are photographs showing the transition of the state in which the ions are supplied to the water stored in the simulated toilet by blowing air, and (f) to (j) are the water stored in the simulated toilet Is a photograph showing a transition of a state in which ions are not supplied by air blowing.
　本試験では、小型の陶器製の擬似便器を使用した。この擬似便器は、便器部分で１５ｃｍ程度の長さを有しており、器形状のボウル部を有している。このボウル部は、吐水および排水の機能を有していない。 In this test, a small pottery simulated toilet bowl was used. This simulated toilet bowl has a length of about 15 cm in the toilet bowl portion and has a bowl-shaped bowl portion. This bowl has no function of water discharge and drainage.
　試験に先立って、スルホコハク酸水溶液（０.００５％）で希釈したカビの胞子懸濁液に１０％のＧＰＢ（栄養成分）を約５０ｍｌ加えて得られた試験用胞子懸濁液を作製した。被試験体として、上記のように構成される２つの擬似便器のボウル部に入れた水に、上記の試験用胞子懸濁液を０.１ｍｌ接種したものを用意した。カビの菌種としては、Cladosporium cladosporioides（ＮＢＲＣ６３４８）を用いた。 Prior to the test, about 50 ml of 10% GPB (nutrient component) was added to a spore suspension of mold diluted with an aqueous solution of sulfosuccinic acid (0.005%) to prepare a spore suspension for test obtained. A test sample was prepared by inoculating 0.1 ml of the above-described spore suspension for test into water contained in the bowl portions of two simulated toilet bowls configured as described above. As a fungal species of fungus, Cladosporium cladosporioides (NBRC6348) was used.
　上記の擬似便器をそれぞれ９０ｃｍ×１８０ｃｍ×２４０ｃｍの立方体の空間に配置した。一方の擬似便器には、空間の天井に配置したイオン発生装置（イオン発生機ＩＧ－ＫＴＡ２０）を配置し、０．１４ｍ／ｓの風によってイオン発生装置で生じたイオンを供給した。他方の擬似便器には、イオンおよび風のいずれも供給しなかった。 The above simulated toilet bowls were placed in cubic spaces of 90 cm × 180 cm × 240 cm, respectively. An ion generator (ion generator IG-KTA 20) disposed on the ceiling of the space was disposed in one simulated toilet, and ions generated by the ion generator were supplied by a wind of 0.14 m / s. Neither the ion nor the wind was supplied to the other simulated toilet.
　便器の実使用状態を想定して、第１日から第４日までと、第７日には、１日に２回、水面が一定になるように注水した後、１０回噴霧し、第１０日には、ボウル部の溶液を水道水と入れ替えた。 Assuming that the toilet bowl is in actual use, from the first day to the fourth day, and on the seventh day, water is injected twice a day so that the water surface becomes constant, and then sprayed 10 times, On the day, the solution in the bowl was replaced with tap water.
　以上のような試験方法によって、イオン発生装置を適用した擬似便器の貯留水と、イオン発生装置を適用していない擬似便器の貯留水とを目視にて観察した。 According to the test method as described above, the stored water of the simulated toilet to which the ion generating device is applied and the stored water of the simulated toilet to which the ion generating device is not applied were visually observed.
　イオン発生装置を適用した擬似便器の貯留水では、図７の（ａ）～（ｅ）にそれぞれ示す第３日、第４日、第７日、第９日、第１０日のいずれにも、菌糸および胞子の形成が確認されなかった。 In the reservoir water of the simulated toilet to which the ion generating apparatus is applied, any of the third day, the fourth day, the seventh day, the ninth day, and the tenth day shown in (a) to (e) of FIG. Mycelial and spore formation was not confirmed.
　一方、イオン発生装置を適用しなかった擬似便器の貯留水では、図７の（ｆ）および（ｇ）にそれぞれ示す第３日および第４日で菌糸の形成が確認され、図７の（ｈ）および（ｉ）にそれぞれ示す第７日および第９日で胞子の形成が、ボウル部が液面の接する環状の線上以外に液面を含めて確認された。また、図７の（ｊ）に示す第１０日では、ボウル部の溶液を水道水に入れ替えても、上記の環状の線上には胞子が残っていた。 On the other hand, in the reservoir water of the simulated toilet to which the ion generating apparatus was not applied, the formation of mycelia was confirmed on the third and fourth days respectively shown in (f) and (g) of FIG. The formation of spores was confirmed on the 7th and 9th days respectively shown in 2.) and (i), including the liquid level other than the annular line where the bowl part is in contact with the liquid level. In addition, on the tenth day shown in (j) of FIG. 7, spores remained on the above annular line even if the solution in the bowl portion was replaced with tap water.
　また、イオン発生装置を適用した擬似便器では、注水および噴霧を行わない期間に、０．１４ｍ／ｓの風によって被試験体の溶液が蒸発しており、溶液の液面が１日あたり５ｍｍ～１０ｍｍ低下していた。 Also, in the simulated toilet with the ion generator applied, the solution of the test sample is evaporated by the wind of 0.14 m / s during the period without water injection and spraying, and the liquid level of the solution is 5 mm per day It has fallen by 10 mm.
　このように、溶液の液面の低下および溶液へのイオンの供給によって、カビの繁殖が抑止されることが確認された。 Thus, it has been confirmed that the growth of mold is suppressed by the lowering of the liquid surface of the solution and the supply of ions to the solution.
　なお、上述した実施形態１～３に記載されたイオン発生装置１，１Ａ，１Ｂは、それぞれ、便蓋４、便座３、便器本体２に取り付け可能に構成されている。これらの構成に限らず、１つのイオン発生装置が、便器本体２、便座３および便蓋４の少なくともいずれか１つに取り付け可能に構成されていてもよい。例えば、イオン発生装置１は、便蓋４だけでなく、便器本体２に取り付け可能であってもよいし、便座３に取り付け可能であってもよいし、あるいは、便器本体２および便座３の両方に取り付け可能であってもよい。イオン発生装置１Ａ，１Ｂについても同じく、取り付け可能な対象を広げることができる。 The ion generating devices 1, 1A and 1B described in the first to third embodiments are configured to be attachable to the toilet lid 4, the toilet seat 3 and the toilet body 2, respectively. Not limited to these configurations, one ion generator may be configured to be attachable to at least one of the toilet body 2, the toilet seat 3, and the toilet lid 4.

　〔まとめ〕
　本発明の態様１に係るカビ抑制装置は、水洗便器装置１００の便器本体２に貯留された貯留水の水面を常時または断続的に変動させる水面変動部（カバー１１、ファン１２、底板１４）を備え、水洗便器装置１００に取り付けられる。 [Summary]
The mold suppression device according to aspect 1 of the present invention is a water surface fluctuation unit (cover 11, fan 12, bottom plate 14) that constantly or intermittently changes the water surface of stored water stored in the toilet body 2 of the flush toilet device 100. It is equipped and attached to the flush toilet bowl apparatus 100.
　上記の構成によれば、常時水面が変動するので、黒ずみの主な原因となる黒カビの繁殖に必要な酸素および水分の供給を絶つことができる。これにより、黒ずみの発生を抑制することができる。 According to the above configuration, since the water surface constantly fluctuates, it is possible to cut off the supply of oxygen and water necessary for the growth of black mold which is the main cause of the darkening. This can suppress the occurrence of darkening.
　本発明の態様２に係るカビ抑制装置は、上記態様１において、前記水面変動部が、前記貯留水の前記水面に送風してもよい。 In the mold suppression device according to aspect 2 of the present invention, in the aspect 1, the water surface fluctuation unit may blow air to the water surface of the stored water.
　上記の構成によれば、水面への送風で貯留水の蒸発が促される。これにより、貯留水の水面が低下していくので、水洗動作によって貯留水の水面が元の位置に戻っても、水面が繰り返して低下していく。それゆえ、黒カビに長時間にわたって水分が供給されない状態をつくり出すことができる。したがって、黒カビの繁殖を抑制することができる。 According to the above configuration, the air blowing to the water surface promotes evaporation of the stored water. As a result, the water surface of the stored water is lowered, so even if the water surface of the stored water returns to the original position by the flush operation, the water surface is repeatedly lowered. Therefore, the black mold can be made to be in a state where water is not supplied for a long time. Therefore, the reproduction of black mold can be suppressed.
　本発明の態様３に係るカビ抑制装置は、上記態様１または２において、イオンを前記水面に供給するイオン供給部（カバー１１、ファン１２、底板１４、イオン発生部１５）をさらに備えていてもよい。 The mold suppression device according to aspect 3 of the present invention further includes an ion supply portion (cover 11, fan 12, bottom plate 14, ion generation portion 15) for supplying ions to the water surface in aspect 1 or 2 above. Good.
　上記の構成によれば、水面に供給されたイオンは便器内に拡散されていき、水面付近に付着した黒カビに作用する。これにより、なお一層黒カビの繁殖を抑制して、黒ずみの発生を抑制する効果を高めることができる。 According to the above configuration, the ions supplied to the water surface are diffused into the toilet bowl and act on black mold attached to the vicinity of the water surface. Thereby, the reproduction of black mold can be further suppressed to enhance the effect of suppressing the occurrence of darkening.
　本発明の態様４に係るカビ抑制装置は、上記態様１から３のいずれかにおいて、前記便器本体２と、前記便器本体２に回動可能に設けられた、水洗便器装置１００に含まれる便座３と、前記便器本体２の開口部２４を開閉するように前記便器本体２に設けられた、前記水洗便器装置１００に含まれる便蓋４との少なくともいずれか１つに、取り付け可能に構成されていてもよい。 The mold suppression device according to aspect 4 of the present invention is the toilet seat 3 included in the flush toilet device 100 rotatably provided on the toilet main body 2 and the toilet main body 2 in any of the above aspects 1 to 3. And at least one of the toilet lid 4 included in the flush toilet device 100 provided in the toilet bowl 2 so as to open and close the opening 24 of the toilet bowl 2. May be
　上記の構成によれば、より貯留水に近い位置で貯留水の水面を変動させることができる。また、カビ抑制装置を便器本体に取り付ける場合、便蓋の有無、便蓋の開閉および便座の上げ下ろしに関わらずカビ抑制装置を動作させることができる。また、カビ抑制装置を便座に取り付ける場合、便蓋の有無および便蓋の開閉に関わらずカビ抑制装置を動作させることができる。また、カビ抑制装置を便蓋に取り付ける場合、便器本体および便座に特別な加工をすることなく、簡易な構造でカビ抑制装置を便器に設けることができる。 According to the above configuration, the water surface of the stored water can be varied at a position closer to the stored water. In addition, when the mold control device is attached to the toilet body, the mold control device can be operated regardless of the presence or absence of the toilet lid, opening and closing of the toilet lid, and lifting and lowering of the toilet seat. Moreover, when attaching a mold suppression apparatus to a toilet seat, the mold suppression apparatus can be operated regardless of the presence or absence of the toilet lid and the opening and closing of the toilet lid. In addition, when the mold control device is attached to the toilet lid, the mold control device can be provided to the toilet bowl with a simple structure without special processing of the toilet body and the toilet seat.
　本発明の態様５に係る水洗便器装置は、上記態様１から４のいずれかのカビ抑制装置が取り付けられている。 The water-washing toilet device according to aspect 5 of the present invention is attached with the mold suppression device according to any one of aspects 1 to 4 above.
　なお、本発明の態様に係るカビ抑制装置は、前記水面変動部が、前記貯留水の水面を低下させてもよい。 In the mold suppression device according to the aspect of the present invention, the water surface fluctuation unit may lower the water surface of the stored water.
　上記の構成によれば、貯留水の水面が低下していくので、黒カビに長時間にわたって水分が供給されない状態をつくり出すことができる。したがって、黒カビの繁殖を抑制することができる。 According to the above configuration, since the surface of the stored water is lowered, it is possible to create a state in which no water is supplied to the black mold over a long period of time. Therefore, the reproduction of black mold can be suppressed.
　また、本発明の他の態様に係るカビ抑制装置は、前記水面変動部が、前記水面を振動させてもよい。 In the mold control device according to another aspect of the present invention, the water surface fluctuation unit may vibrate the water surface.
　上記の構成によれば、水面が振動すると、水面線付近の黒カビへの酸素の供給が十分行われなくなる。これにより、黒カビの繁殖を抑制することができる。 According to the above configuration, when the water surface vibrates, supply of oxygen to black mold near the water surface line is not sufficiently performed. Thereby, the reproduction of black mold can be suppressed.
　また、本発明の他の態様に係るカビ抑制装置は、前記水面変動部が、前記水面に送風することにより前記水面を振動させてもよい。 In the mold control device according to another aspect of the present invention, the water surface fluctuation unit may vibrate the water surface by blowing air to the water surface.
　上記の構成によれば、機械的に水面を振動させる手法等に比べて簡素かつ容易に水面を低下させることができる。 According to the above configuration, the water surface can be lowered simply and easily as compared to a method of mechanically vibrating the water surface or the like.
