Description

本発明は、浴槽に設けられた洗浄ノズルから洗剤液、湯又は水等を浴槽内に噴射して浴槽の自動洗浄を行うための浴槽洗浄ユニットに関するものである。   The present invention relates to a bathtub washing unit for automatically washing a bathtub by injecting a detergent solution, hot water, water or the like into the bathtub from a washing nozzle provided in the bathtub.

従来より、浴槽内の汚れを自動的に洗浄する浴槽洗浄装置が知られている（特許文献１、特許文献２等）。この浴槽洗浄装置は、概略的には、図５に示すように、浴槽１０２内に設けた洗浄ノズル１１１と、この洗浄ノズル１１１に一端側を接続し他端側を給湯器１０３に接続した洗浄管１１３とを有し、この洗浄管１１３の途中に洗剤を送り込む洗剤供給管１１４を接続した洗剤混合部１０５を設けた構成となっている。洗剤供給管１１４は、洗剤原液を貯留する洗剤タンク１１２に接続されている。なお、洗浄管１１３には、洗剤混合部１０５の上流側に開閉弁１９１、水量センサ１９２、水量制御弁１９３が設けられている。そして、浴槽洗浄運転は、洗浄ノズル１１１から、湯又は水を噴射させるすすぎ洗浄と、湯又は水に洗剤混合部１０５で洗剤を混合した洗剤液を噴射させる洗剤洗浄とを組み合わせて行われる。これによって、浴槽１０２内の湯垢がきれいに洗い流されることとなる。
特許第３５９８８０８号公報 特許第３８２１０１４号公報 Conventionally, a bathtub cleaning device that automatically cleans dirt in a bathtub is known (Patent Document 1, Patent Document 2, etc.). As shown in FIG. 5, this bathtub cleaning apparatus schematically includes a cleaning nozzle 111 provided in the bathtub 102, and a cleaning nozzle 111 having one end connected to the cleaning nozzle 111 and the other end connected to a water heater 103. The detergent mixing unit 105 is provided with a pipe 113 and a detergent supply pipe 114 that feeds detergent into the middle of the washing pipe 113. The detergent supply pipe 114 is connected to a detergent tank 112 that stores a detergent stock solution. The cleaning pipe 113 is provided with an on-off valve 191, a water amount sensor 192, and a water amount control valve 193 on the upstream side of the detergent mixing unit 105. Then, the bathtub cleaning operation is performed by combining rinsing cleaning in which hot water or water is jetted from the cleaning nozzle 111 and detergent cleaning in which a detergent liquid obtained by mixing detergent in the hot water or water in the detergent mixing unit 105 is jetted. As a result, the scale in the bathtub 102 is washed away cleanly.
Japanese Patent No. 3598808 Japanese Patent No. 3821014

しかしながら、浴槽１０２内の汚れは、カビや酵母菌等が繁殖して浴槽１０２内の各部に強固に固着することが大きな問題の一つとなっている。このカビや酵母は、湯垢のみならず洗剤をも餌として繁殖するため、湯垢がきれいに落ちたとしても、洗剤が残っているとこの洗剤を餌として発生する。   However, the dirt in the bathtub 102 is one of the major problems that molds, yeasts, etc. propagate and firmly adhere to each part in the bathtub 102. Since this mold and yeast propagate not only as a scale but also as a detergent, even if the scale falls off cleanly, this detergent is generated as a bait if the detergent remains.

しかるに、上記従来の浴槽洗浄装置では、浴槽１０２内の隅々まで湯垢を完全に洗い流すことは困難であり、また、噴射した洗剤液の洗剤が浴槽１０２内に残ることもある。従って、浴槽１０２内を洗浄したにもかかわらず、カビや酵母菌等が湯垢や洗剤等を餌として繁殖してしまう。従って、次の入浴時に湯張りされるまでには浴槽１０２内がカビや酵母菌等により汚染されて清潔に保つことが困難であった。   However, in the conventional bathtub cleaning device, it is difficult to completely wash away the scale to every corner of the bathtub 102, and the sprayed detergent liquid detergent may remain in the bathtub 102. Therefore, even though the inside of the bathtub 102 is washed, molds, yeasts, and the like are propagated using scales, detergents, and the like as food. Accordingly, it is difficult to keep the inside of the bath 102 clean by being contaminated with mold, yeast, or the like until the bath is filled with the next bath.

一方、給湯器において浴槽へ湯張りするための湯張り管に銀イオン発生器を設け、湯張り温水に銀イオンを溶解させるもの（特開２００６−１３８５８８号公報）や、給湯器の追焚通路に銀イオン発生器を設け、浴槽内の浴槽水を銀イオン発生装置に循環させて浴槽水中に銀イオンを一定量添加させるものがある（特開平１１−２７６３６７号公報の段落００３７、段落００３８、図３）。これらは、銀イオンの殺菌作用によって浴槽水の殺菌を行うことができるとしている。
しかし、浴槽水を殺菌しても浴槽水は入浴によって人体の脂質等により汚れるため、入浴後に浴槽内の浴槽水を排水すると、この浴槽水の汚れが浴槽内壁、循環金具、排水口等に付着した状態となる。そのため、このまま放置しておくと、浴槽の各部にはカビや酵母菌等が繁殖して汚染され、その結果、次の入浴時に湯張りされるまでには浴槽の各部にはカビや酵母菌等により汚染され浴槽内を清潔に保つことが困難であった。 On the other hand, in a water heater, a silver ion generator is provided in a hot water tube for hot water filling in a bathtub, and silver ions are dissolved in hot water hot water (Japanese Patent Laid-Open No. 2006-138588), or a hot water supply memorial passage A silver ion generator is provided to circulate the bathtub water in the bathtub to the silver ion generator to add a certain amount of silver ions to the bathtub water (paragraph 0037, paragraph 0038 of JP-A-11-276367, FIG. 3). These are supposed to be able to sterilize bathtub water by the sterilization action of silver ions.
However, even if the bath water is sterilized, the bath water is contaminated by the lipids of the human body when bathing, so when the bath water in the bath is drained after bathing, the bath water stains adhere to the inner wall of the bath, circulation fittings, drain outlet, etc. It will be in the state. Therefore, if it is left as it is, mold, yeast, etc. propagate in each part of the bath and become contaminated. As a result, mold, yeast, etc. It was difficult to keep the inside of the bathtub clean.

本発明は、上記事情に鑑みてなされたものであり、浴槽内におけるカビや酵母菌等の繁殖を確実に抑制して次の入浴時まで浴槽内を清潔に保つことができる浴槽洗浄ユニットを提供することを課題とする。   The present invention has been made in view of the above circumstances, and provides a bathtub washing unit that can reliably suppress the growth of mold, yeast, etc. in the bathtub and keep the bathtub clean until the next bathing. The task is to do.

本発明に係る浴槽洗浄ユニットは、
浴槽に設けられた洗浄ノズルから洗剤液、湯又は水等を浴槽内に噴射して浴槽の自動洗浄を行うための浴槽洗浄ユニットであって、
上記洗浄ノズルに一端側が接続され、他端側が湯又は水の供給源に接続されて湯又は水が導入される洗浄管と、
洗剤を貯留する洗剤タンクに接続されて洗剤が導入される洗剤供給管とを有し、
上記洗浄管には、上記洗剤供給管が接続されて洗浄管内に流れる湯又は水に対し洗剤供給管から流入される洗剤を混合する洗剤混合部が設けられ、この洗剤混合部より上流側には洗浄管内に流れる湯又は水に対し銀イオンを混入させる銀電極を備える銀イオン発生装置が設けられている。 The bathtub cleaning unit according to the present invention is
A bathtub cleaning unit for automatically cleaning a bathtub by spraying detergent liquid, hot water or water into the bathtub from a cleaning nozzle provided in the bathtub,
One end side is connected to the cleaning nozzle, the other end side is connected to a hot water or water supply source and hot water or water is introduced, and
A detergent supply pipe connected to a detergent tank for storing detergent and into which detergent is introduced;
The cleaning pipe is provided with a detergent mixing section that is connected to the detergent supply pipe and mixes the detergent flowing from the detergent supply pipe with hot water or water flowing in the cleaning pipe, and upstream of the detergent mixing section. A silver ion generator is provided that includes a silver electrode that mixes silver ions into hot water or water flowing in the cleaning tube.

これによれば、銀イオン発生装置を洗浄管に設けることにより、銀イオンを含む湯又は水を洗浄ノズルから浴槽内に噴射させる銀イオン洗浄を行うことができる。従って、浴槽内に銀イオンが付着されるので、銀イオンの抗菌、除菌効果によって浴槽内でのカビや酵母菌等の繁殖を防止することができる。
また、洗浄管において、銀イオン発生装置を洗剤混合部の上流側に設けることにより、洗剤洗浄時に洗剤液が銀イオン発生装置に流れることがない。従って、洗剤液が銀イオン発生装置の銀電極と接触することが防止され、銀電極に洗剤が付着して銀イオンの発生性能が劣化されることもない。 According to this, by providing the silver ion generator in the cleaning tube, it is possible to perform silver ion cleaning in which hot water or water containing silver ions is jetted from the cleaning nozzle into the bathtub. Therefore, since silver ion adheres in a bathtub, propagation of mold, yeast, etc. in a bathtub can be prevented by the antibacterial and sterilization effect of silver ion.
Further, by providing the silver ion generating device upstream of the detergent mixing section in the cleaning tube, the detergent liquid does not flow to the silver ion generating device during cleaning with the detergent. Therefore, the detergent liquid is prevented from coming into contact with the silver electrode of the silver ion generator, and the detergent does not adhere to the silver electrode and the silver ion generation performance is not deteriorated.

上記洗浄管には、上記洗剤混合部より上流側に逆流防止装置が設けられ、上記銀イオン発生装置は、上記逆流防止装置より上流側に設けられるように構成してもよい。
これにより、断水等による負圧の発生によって逆流が生じても洗剤混合部で混合された洗剤液が逆流防止装置より上流側に流れ込むことが上記逆流防止装置によって阻止される。また、銀イオン発生装置を上記逆流防止装置の上流側に設けるので、洗剤液が銀イオン発生装置の銀電極と接触することが確実に防止され、銀電極に洗剤が付着して銀イオンの発生性能が劣化されることもない。 The cleaning pipe may be provided with a backflow prevention device upstream from the detergent mixing unit, and the silver ion generation device may be provided upstream from the backflow prevention device.
Thereby, even if a reverse flow occurs due to the generation of a negative pressure due to water breakage or the like, the reverse flow prevention device prevents the detergent liquid mixed in the detergent mixing unit from flowing upstream from the reverse flow prevention device. In addition, since the silver ion generator is provided on the upstream side of the backflow prevention device, the detergent solution is reliably prevented from coming into contact with the silver electrode of the silver ion generator, and the detergent adheres to the silver electrode and silver ions are generated. Performance is not degraded.

また、本発明に係る浴槽洗浄ユニットは、
浴槽に設けられた洗浄ノズルから洗剤液、湯又は水等を浴槽内に噴射して浴槽の自動洗浄を行うための浴槽洗浄ユニットであって、
上記洗浄ノズルに一端側が接続され、他端側が湯又は水の供給源に接続されて湯又は水が供給される洗浄管と、
洗剤を貯留する洗剤タンクに接続されて洗剤が供給される洗剤供給管とを有し、
上記洗浄管には、上記洗剤供給管が接続されて洗浄管内に流れる湯又は水に対し洗剤供給管から流入される洗剤を混合する洗剤混合部が設けられ、この洗剤混合部より上流側に流路切替弁が設けられ、この流路切替弁には上記洗剤混合部をバイパスする第二の洗浄管が接続され、
上記第二の洗浄管には、この第二の洗浄管内に流れる湯又は水に対し銀イオンを混入させる銀電極を備える銀イオン発生装置が設けられている。 The bathtub cleaning unit according to the present invention is
A bathtub cleaning unit for automatically cleaning a bathtub by spraying detergent liquid, hot water or water into the bathtub from a cleaning nozzle provided in the bathtub,
One end side is connected to the cleaning nozzle, and the other end side is connected to a hot water or water supply source to supply hot water or water; and
A detergent supply pipe connected to a detergent tank for storing detergent and supplied with detergent;
The cleaning pipe is connected to the detergent supply pipe, and is provided with a detergent mixing section that mixes the detergent flowing in from the detergent supply pipe with hot water or water flowing in the cleaning pipe, and flows upstream from the detergent mixing section. A path switching valve is provided, and a second cleaning pipe that bypasses the detergent mixing unit is connected to the channel switching valve,
The second cleaning pipe is provided with a silver ion generating device provided with a silver electrode for mixing silver ions into hot water or water flowing in the second cleaning pipe.

これによれば、第二の洗浄管内に銀イオン発生装置を設けることにより、流路切替弁を第二の洗浄管側に切替えて銀イオンを含む湯又は水を洗浄ノズルから浴槽内に噴射させる銀イオン洗浄を行うことができる。従って、浴槽内に銀イオンが付着されるので、銀イオンの抗菌、除菌効果によって浴槽内でのカビや酵母菌等の繁殖を防止することができる。
また、銀イオン発生装置は、洗剤混合部をバイパスする第二の洗浄管に設けられ、この第二の洗浄管の上流端に流路切替弁が設けられているので、流路切替弁を洗剤混合部側に切り替えて、第二の洗浄管側を全閉にした際に洗剤混合部で混合された洗剤液が第二の洗浄管に流れ込むことが阻止される。従って、洗剤液が第二の洗浄管に設けた銀イオン発生装置の銀電極と接触することが防止され、銀電極に洗剤が付着して銀イオンの発生性能が劣化されることもない。 According to this, by providing a silver ion generator in the second cleaning pipe, the flow path switching valve is switched to the second cleaning pipe side, and hot water or water containing silver ions is injected from the cleaning nozzle into the bathtub. Silver ion cleaning can be performed. Therefore, since silver ion adheres in a bathtub, propagation of mold, yeast, etc. in a bathtub can be prevented by the antibacterial and sterilization effect of silver ion.
Moreover, since the silver ion generator is provided in the 2nd washing pipe which bypasses a detergent mixing part, and the flow-path switching valve is provided in the upstream end of this 2nd washing pipe, a flow-path switching valve is detergent.

上記浴槽洗浄運転は、上述のすすぎ洗浄、洗剤洗浄、銀イオン洗浄の組み合わせより行われる。そして、上記銀イオン洗浄は浴槽洗浄運転の最後に行われる。上記浴槽洗浄運転の一例として、例えば、すすぎ洗浄（予備すすぎ）、洗剤洗浄、すすぎ洗浄（仕上げすすぎ）、銀イオン洗浄がこの順に行われる。   The bathtub cleaning operation is performed by a combination of the above-described rinse cleaning, detergent cleaning, and silver ion cleaning. The silver ion cleaning is performed at the end of the bathtub cleaning operation. As an example of the bath cleaning operation, for example, rinsing cleaning (preliminary rinsing), detergent cleaning, rinsing cleaning (finish rinsing), and silver ion cleaning are performed in this order.

このように、実施の形態１の浴槽洗浄ユニット１によれば、銀イオン洗浄によって、浴槽２の内壁面や浴槽蓋２２の下面に銀イオンが付着され、また同時に、浴槽２の排水口２３や洗浄ノズル１１等にも銀イオンが付着される。そして、この銀イオン洗浄が浴槽洗浄の最後に行われることで、浴槽２内の上記各部には銀イオンが付着された状態に維持されるので、銀イオンの抗菌、除菌効果により、これらの場所でのカビや酵母菌などの繁殖を防止することができる。その結果、浴槽洗浄後から次回の湯張り時まで浴槽２内を清潔に保つことができる。   Thus, according to the bathtub cleaning unit 1 of Embodiment 1, silver ions adhere to the inner wall surface of the bathtub 2 and the lower surface of the bathtub lid 22 by silver ion cleaning, and at the same time, the drain outlet 23 of the bathtub 2 Silver ions adhere to the cleaning nozzle 11 and the like. And since this silver ion washing | cleaning is performed at the end of bathtub washing | cleaning, since the silver ion is maintained in the said each part in the bathtub 2, these antibacterial and disinfection effects of silver ions, these It is possible to prevent the growth of mold and yeast in the place. As a result, the inside of the bathtub 2 can be kept clean after the bathtub is washed until the next hot water filling.

なお、この銀イオン洗浄のとき、コントローラ１０は、給湯器３の制御部（図示せず）に燃焼禁止信号を出力し、給湯器３から熱交換加熱されない水が洗浄管１３に導入されるようにしてもよい。これにより、洗浄ノズル１１からは、銀イオンを混入した水が噴射され、浴槽２自体を冷ますことができるので、高温多湿下で繁殖しやすいカビや酵母菌等の発生を抑えるのに有効である。   At the time of this silver ion cleaning, the controller 10 outputs a combustion inhibition signal to a control unit (not shown) of the water heater 3 so that water that is not heat-exchanged and heated from the water heater 3 is introduced into the cleaning pipe 13. It may be. Thereby, water mixed with silver ions is jetted from the washing nozzle 11 and the bath 2 itself can be cooled, which is effective in suppressing the generation of molds and yeasts that are likely to breed under high temperature and high humidity. is there.

また、銀イオン発生装置７は、洗浄管１３において洗剤混合部５より上流側に設けられている。これにより、上記洗剤洗浄時に洗剤液が銀イオン発生装置７に流れることがない。従って、洗剤液が銀イオン発生装置７の銀電極７３と接触することが防止され、銀電極７３に洗剤が付着して銀イオンの発生性能が劣化されることもない。   The silver ion generator 7 is provided upstream of the detergent mixing unit 5 in the cleaning tube 13. Thereby, a detergent liquid does not flow into the silver ion generator 7 at the time of the said detergent washing | cleaning. Accordingly, the detergent liquid is prevented from coming into contact with the silver electrode 73 of the silver ion generator 7, and the detergent does not adhere to the silver electrode 73 and the silver ion generation performance is not deteriorated.

また、洗浄管１３において洗剤混合部５より上流側に逆流防止装置６が設けられており、そして、銀イオン発生装置７はこの逆流防止装置６より上流側に設けられている。上記逆流防止装置６は、例えば、逆流防止弁等によって構成されており、断水等により洗浄管１３内に負圧発生等の圧力異常が起こっても洗剤混合部５で混合された洗剤液がこの逆流防止装置６よってこれより上流側に流れ込むことが阻止される。従って、洗浄管１３内に圧力異常が起こっても洗剤液が銀イオン発生装置７の銀電極７３と接触することが確実に防止され、銀電極７３に洗剤が付着して銀イオンの発生性能が劣化されることもない。   Further, a backflow prevention device 6 is provided upstream of the detergent mixing section 5 in the cleaning tube 13, and the silver ion generator 7 is provided upstream of the backflow prevention device 6. The backflow prevention device 6 is constituted by, for example, a backflow prevention valve or the like, and the detergent liquid mixed in the detergent mixing unit 5 is not removed even if a pressure abnormality such as generation of negative pressure occurs in the washing tube 13 due to water cut or the like. The backflow prevention device 6 prevents the flow upstream. Therefore, even if a pressure abnormality occurs in the cleaning tube 13, the detergent liquid is reliably prevented from coming into contact with the silver electrode 73 of the silver ion generator 7, and the detergent adheres to the silver electrode 73 and the silver ion generation performance is improved. There is no deterioration.

一方、図２に示すように、銀イオン発生装置７の筒体７０は、一方の接続口部７６を有する連結管部７１と、他方の接続口部７７を有する銀イオン生成管部７２とを備えており、上記の各接続口部７６，７７が洗浄管１３に接続されている。銀電極７３は、銀イオン生成管部７２に内蔵されている。なお、連結管部７１と銀イオン生成管部７２の外周囲には、二分割の外装ケース７４，７５が配置されている。そして、銀イオン生成管部７２は、連結管部７１に対してカートリッジ式に取替え可能に取り付けられている。すなわち、銀イオン生成管部７２は、そのフランジ部７２ａに連結管部７１のレバー式係止部７１ａを係合させて連結管部７１に取り付けられている。従って、連結管部７１のレバー式係止部７１ａを銀イオン生成管部７２のフランジ部７２ａから係合解除させることで銀イオン生成管部７２が連結管部７１から取外される。   On the other hand, as shown in FIG. 2, the cylindrical body 70 of the silver ion generation device 7 includes a connecting pipe portion 71 having one connection port portion 76 and a silver ion generation tube portion 72 having the other connection port portion 77. The connection ports 76 and 77 are connected to the cleaning pipe 13. The silver electrode 73 is built in the silver ion generation tube portion 72. In addition, on the outer periphery of the connecting pipe portion 71 and the silver ion generating pipe portion 72, two divided outer cases 74 and 75 are arranged. And the silver ion production | generation pipe | tube part 72 is attached to the connection pipe | tube part 71 so that replacement | exchange is possible with a cartridge type. That is, the silver ion generating tube portion 72 is attached to the connecting tube portion 71 by engaging the lever type locking portion 71a of the connecting tube portion 71 with the flange portion 72a. Therefore, the silver ion generating tube portion 72 is detached from the connecting tube portion 71 by disengaging the lever-type locking portion 71 a of the connecting tube portion 71 from the flange portion 72 a of the silver ion generating tube portion 72.

このように、銀イオン発生装置７の銀電極７３は、洗浄管１３には一体形成せずに、銀イオン生成管部７２に内蔵されてこの銀イオン生成管部７２ごと取替え可能に構成されている。従って、銀イオン発生装置７の銀電極７３が経時使用によって消耗しても、銀イオン生成管部７２を新たなものと交換することができる。よって、銀電極７３の消耗具合に応じて銀イオン生成管部７２を適時交換することにより、銀イオン発生装置７の銀イオン発生性能が維持される。   Thus, the silver electrode 73 of the silver ion generator 7 is not formed integrally with the cleaning tube 13 but is built in the silver ion generation tube portion 72 so that the entire silver ion generation tube portion 72 can be replaced. Yes. Therefore, even if the silver electrode 73 of the silver ion generator 7 is consumed due to use over time, the silver ion generation tube portion 72 can be replaced with a new one. Therefore, the silver ion generation performance of the silver ion generator 7 is maintained by exchanging the silver ion generation tube portion 72 in a timely manner according to the consumption level of the silver electrode 73.

＜変形例＞
上記銀イオン発生装置７は、洗浄管１３において逆流防止装置６より上流側に設けているが、図３に示すように、銀イオン発生装置７は、洗浄管１３において洗剤混合部５より上流側に設けられるが、逆流防止装置６より下流側に設けるようにしてもよい。この場合、逆流防止装置６によって、銀イオン発生装置７で銀イオンが混入された湯又は水が洗浄管１３を逆流して給湯器３の出湯管３３内に流入して出湯管端末３３ａから出湯されることが阻止される。
また、図１に示す浴槽洗浄ユニット１において、洗浄管１３には銀イオン発生装置７の上流位置に第二の逆流防止装置を設け、銀イオン発生装置７を２つの逆流防止装置の間に配置するようにしてもよい。これにより、銀イオン発生装置７に洗剤液が流れ込むことが防止されると共に、給湯器３の出湯管３３側に銀イオンを含む湯又は水が流れ込むことが防止される。 <Modification>
The silver ion generator 7 is provided upstream of the backflow prevention device 6 in the cleaning tube 13, but as shown in FIG. 3, the silver ion generator 7 is upstream of the detergent mixing unit 5 in the cleaning tube 13. However, it may be provided downstream of the backflow prevention device 6. In this case, the backflow prevention device 6 causes the hot water or water mixed with silver ions in the silver ion generation device 7 to flow back through the washing tube 13 and flow into the hot water discharge pipe 33 of the hot water supply device 3 and take out the hot water from the hot water discharge pipe terminal 33a. Is prevented.
In the bathtub cleaning unit 1 shown in FIG. 1, the cleaning pipe 13 is provided with a second backflow prevention device upstream of the silver ion generation device 7, and the silver ion generation device 7 is disposed between the two backflow prevention devices. You may make it do. This prevents the detergent liquid from flowing into the silver ion generator 7 and prevents hot water or water containing silver ions from flowing into the outlet pipe 33 side of the water heater 3.

＜実施形態２＞
図４に示すように、実施の形態２の浴槽洗浄ユニット１は、洗浄管１３には、洗剤混合部５をバイパスし、洗剤混合部５と並列に銀イオン発生装置７を配置するためのバイパス管（第二の洗浄管）１５が接続されている。すなわち、洗浄管１３において、洗剤混合部５の上流位置に２方向式の流路切替弁９５が設けられており、この流路切替弁９５にバイパス管１５の上流端が接続され、このバイパス管１５の下流端が洗剤混合部５の下流位置に接続されている。そして、このバイパス管１５に銀イオン発生装置７が設けられている。なお、洗浄管１３において流路切替弁９５の上流位置には逆流防止装置６が設けられている。 <Embodiment 2>
As shown in FIG. 4, the bathtub cleaning unit 1 according to the second embodiment bypasses the detergent mixing unit 5 in the cleaning tube 13 and bypasses the silver ion generator 7 disposed in parallel with the detergent mixing unit 5. A tube (second cleaning tube) 15 is connected. That is, in the cleaning pipe 13, a two-way flow path switching valve 95 is provided at an upstream position of the detergent mixing unit 5, and the upstream end of the bypass pipe 15 is connected to the flow path switching valve 95. The downstream end of 15 is connected to the downstream position of the detergent mixing unit 5. The bypass pipe 15 is provided with a silver ion generator 7. A backflow prevention device 6 is provided in the cleaning pipe 13 at a position upstream of the flow path switching valve 95.

この場合、流路切替弁９５は、浴槽洗浄運転時に洗浄ノズル１１から湯又は水を噴射させるすすぎ洗浄及び洗剤液を噴射させる洗剤洗浄を行うときは、湯又は水が洗剤混合部５を配置する洗浄管１３側にのみ流れ込むように流路が切り替えられ、洗浄ノズル１１から銀イオンを混入した湯又は水を噴射させる銀イオン洗浄を行うときは、湯又は水がバイパス管１５側にのみ流れ込むように流路が切り替えられる。   In this case, the flow path switching valve 95 arranges the detergent mixing unit 5 when performing rinse cleaning in which hot water or water is sprayed from the cleaning nozzle 11 and detergent cleaning in which a detergent liquid is sprayed during the bathtub cleaning operation. When the flow path is switched so as to flow only into the cleaning pipe 13 side and silver ion cleaning is performed by injecting hot water or water mixed with silver ions from the cleaning nozzle 11, the hot water or water flows only into the bypass pipe 15 side. The flow path is switched.

このように、実施の形態２の浴槽洗浄ユニット１によれば、銀イオン発生装置７は、洗剤混合部５をバイパスするバイパス管１５に設けられ、このバイパス管１５の上流端に流路切替弁９５が設けられているので、流路切替弁９５を洗剤混合部５側に切り替えて、バイパス管１５側を全閉にした際に洗剤混合部５で混合された洗剤液がバイパス管１５に流れ込むことが阻止される。従って、洗剤液がバイパス管１５に設けた銀イオン発生装置７の銀電極７３と接触することが防止され、銀電極７３に洗剤が付着して銀イオンの発生性能が劣化されることもない。   Thus, according to the bathtub cleaning unit 1 of the second embodiment, the silver ion generator 7 is provided in the bypass pipe 15 that bypasses the detergent mixing unit 5, and a flow path switching valve is provided at the upstream end of the bypass pipe 15. 95 is provided, the detergent liquid mixed in the detergent mixing section 5 flows into the bypass pipe 15 when the flow path switching valve 95 is switched to the detergent mixing section 5 side and the bypass pipe 15 side is fully closed. That is blocked. Accordingly, the detergent liquid is prevented from coming into contact with the silver electrode 73 of the silver ion generator 7 provided in the bypass pipe 15, and the detergent does not adhere to the silver electrode 73 and the generation performance of silver ions is not deteriorated.

しかも、洗浄管１３において流路切替弁９５の上流位置には逆流防止装置６が設けられているので、この逆流防止装置６によって洗剤液や銀イオンを含む湯又は水が給湯器３の出湯管３３内に流入して出湯管端末３３ａから出湯されることが阻止される。
なお、実施の形態２の浴槽洗浄ユニット１におけるその他の構成及び作用効果は、上記実施の形態１の場合と同様である。 Moreover, since the backflow prevention device 6 is provided upstream of the flow path switching valve 95 in the cleaning pipe 13, the backflow prevention device 6 allows hot water or water containing detergent liquid or silver ions to flow out from the hot water supply pipe 3. The hot water is prevented from flowing into the hot water outlet 33 and discharged from the hot water outlet terminal 33a.
In addition, the other structure and effect in the bathtub cleaning unit 1 of Embodiment 2 are the same as that of the case of the said Embodiment 1. FIG.

＜変形例＞
上記バイパス管１５において、銀イオン発生装置７の下流位置に第二の逆流防止装置を設けるようにしてもよい。これによれば、第二の逆流防止装置によって、バイパス管１５の下流端が洗浄管１３に合流された合流部から洗剤液がバイパス管１５内に逆流することが阻止される。従って、この合流部から洗剤液がバイパス管１５に流れ込んで銀イオン発生装置７と接触することが防止され、銀電極７３に洗剤が付着して銀イオンの発生性能が劣化されることもない。
また、浴槽２に第二の洗浄ノズルを設け、バイパス管１５の下流端を洗浄管１３に合流させずに第二の洗浄ノズルに接続するようにしてもよい。この場合、上記銀イオン洗浄は、この第二の洗浄ノズルによって行われる。これによっても、バイパス管１５の下流側から洗剤液がバイパス管１５に流れ込んで銀イオン発生装置７と接触することがなく、銀電極７３に洗剤が付着して銀イオンの発生性能が劣化されることもない。 <Modification>
In the bypass pipe 15, a second backflow prevention device may be provided at a downstream position of the silver ion generator 7. According to this, the second backflow prevention device prevents the detergent liquid from flowing back into the bypass pipe 15 from the joining portion where the downstream end of the bypass pipe 15 joins the cleaning pipe 13. Therefore, the detergent solution is prevented from flowing into the bypass pipe 15 from this junction and coming into contact with the silver ion generator 7, and the detergent does not adhere to the silver electrode 73 and the silver ion generation performance is not deteriorated.
Alternatively, a second cleaning nozzle may be provided in the bathtub 2 so that the downstream end of the bypass pipe 15 is connected to the second cleaning nozzle without joining the cleaning pipe 13. In this case, the silver ion cleaning is performed by the second cleaning nozzle. Also by this, the detergent liquid does not flow into the bypass pipe 15 from the downstream side of the bypass pipe 15 and comes into contact with the silver ion generator 7, and the detergent adheres to the silver electrode 73 and the silver ion generation performance is deteriorated. There is nothing.
