Description

【０００１】
【発明の属する技術分野】
本発明は給水管路に浄水器を介装した連続通水式電解水生成装置の洗浄・殺菌方法及びこの方法を実施する機構を備えた連続通水式電解水生成装置並びにこれに使用される流路切換弁装置に関する。
【０００２】
【発明の技術背景】
水道水等の水を、必要に応じてミネラル等を添加しながら、電解してアルカリイオン水と酸性水に整水する連続通水式電解水生成装置は、長時間使用したのちは電解槽及び管路の洗浄・殺菌が必要になる。特に、陰極室や電解隔膜にはカルシウムなどの析出物が付着するため、定期的あるいは不定期に析出物を除去する必要がある。
【０００３】
【発明が解決しようとする課題】
従来からこの種の電解水生成装置の洗浄は、電解整水操作を止めた状態で給水管からの水を電解槽に給水する事によって電解槽及び管路を洗浄していた。しかしながら、この方法は給水管に浄水器を介装した電解整水装置にあっては浄水器によって塩素が取り除かれた水で洗浄されることになるため、充分な殺菌効果を得ることができなかった。
【０００４】
また、カルシウムなどの析出物を除去するための洗浄方法としては、通常の電解整水運転を止めて電解槽の電極極性を逆転する洗浄専用の逆電洗浄方式、あるいは、通常のアルカリイオン水生成運転中に電極の極性を一定時間毎に切換える逆電電解方式がある。
しかしながら、前者の洗浄専用の逆電洗浄方式は水を多く消費するため不経済であり、後者の逆電電解方式は、極性が逆転してもアルカリ水が常に同じ蛇口から得られるようにするために流路切換バルブやその連動作動機能が必要になるほか、陽極−陰極両用に使用でき、しかも、有害物質が溶出しない高価な電極（例えば白金メッキを施したチタン電極など）が必要になり、製品のコストが高くなる。さらに問題なのは、これらの方式は、いずれも、洗浄されるのは電解槽の陰極室とその排水管路だけであり、浄水器の下流側水回路全体を洗浄・殺菌することはできなかったことである。
【０００５】
したがって、本発明の第１の目的は、水道水などの洗浄水、さらに好ましくは殺菌力の強い次亜塩素酸水で電解槽及びその周辺の管路を効率的に洗浄・殺菌することができる連続通水式電解水生成装置の洗浄・殺菌方法を提供することにある。
【０００６】
本発明の第２の目的は、上記の洗浄・殺菌方法を実施する機構を備えた連続通水式電解水生成装置を提供することにある。
【０００７】
本発明の第３の目的は、この装置の洗浄・殺菌操作に使用される洗浄時流路切換弁装置を提供することにある。
【０００８】
【課題を解決するための手段】
上記第１の目的を達成するために、本願の請求項１の発明は、給水管路から供給される水を陰極室と陽極室を有する電解槽で電解し、電解によって生成されたアルカリ水と酸性水を一対の排水管路から各別に排出する連続通水式電解水生成装置の洗浄方法において、洗浄の際、給水管路から電解槽入口への給水を抑制して電解槽の一方の電極室の出口側から洗浄水を給水し、該一方の電極室を逆流させた供給水を、直接又は給水側の管路を介して、他方の電極室へ通水しながら該他方の電極室の排水管路から排水することを特徴とする。
【０００９】
また、上記第１の目的を達成するために、本願の請求項２の発明は、陰極室と陽極室を有する電解槽の給水管路に、浄水器を介装し、浄水器の共通排水部から一対の給水支管を介して電解槽の陰極室と陽極室に独立に給水するとともに、給水された水をアルカリ水と酸性水に電解して一対の排水管路から各別に排出する連続通水式電解水生成装置の洗浄方法において、洗浄時に、給水管路から電解槽入口への給水を抑制して電解槽の一方の電極室の出口側から給水し、該一方の電極室を逆流させた供給水を、浄水器の共通排水部を経由する一対の給水支管を介して電解槽の他方の電極室へ通水しながら該他方の電極室の排水管路から排水することを特徴とする。
【００１０】
さらに、上記第１の目的を達成するために、本願の請求項３の発明は、陰極室と陽極室を有する電解槽の給水管路を、各々の電解室に独立に連通する一対の給水管路に分岐するとともに、電解槽の陰極室に通ずる給水支管、又はその上流側の前記給水管路、もしくは前記給水管路と陰極室側給水支管に吸着浄水器と濾過浄水器を上流、下流の位置関係で介装し、電解槽の各電極室に給水された水をアルカリ水と酸性水に電解して一対の排水管路から排出する連続通水式電解水生成装置の洗浄方法において、洗浄時に、給水管路から電解槽入口への給水を抑制して電解槽の一方の電極室の出口側から給水し、該一方の電極室を逆流させた供給水を、前記濾過浄水器を経由させて電解槽の他方の電極室へ通水しながら該他方の電極室の排水管路から排水することを特徴とする
【００１１】
上記いずれの場合も、請求項４に記載したように、電解槽の一方の排水管路から給水される側の電極室の電極を陽極にして電解槽を通る水を電解することにより、該陽極電極室に次亜塩素酸殺菌水を生成し、この次亜塩素酸殺菌水を洗浄水として通水する過程で前記洗浄水回路を洗浄・殺菌し、且つ、この次亜塩素酸殺菌水を陰極電極室に通す過程で中和して排出するのがさらに好ましい。
【００１２】
上記第２の目的を達成するために、本願の請求項５の発明は、陰極室と陽極室に仕切った電解槽の一側に、浄水器を介装した給水管路を有するとともに、他側に前記陰極室と陽極室に各別に連通する一対の排水管路を有し、給水管路から供給される水をアルカリイオン水と酸性水に電解して前記一対の排水管路から排出する連続通水式の電解水生成装置において、浄水器の共通排水部から電解槽の各々の電極室に各別に連通する一対の給水支管を設け、給水管路から電解槽入口への給水を抑制した状態で、電解槽の一方の電極室の出口側から水を給水したときに、給水された水が該一方の電極室を逆流し、浄水器の共通排水部を経由する一対の給水支管を通って電解槽の他方の電極室へ流れ、該他方の電極室の排水管路から排水されるようにしたことを特徴とする
【００１３】
上記第２の目的を達成するために、本願の請求項６の発明は、陰極室と陽極室に仕切った電解槽の一側に、浄水器を介装した給水管路を有するとともに、他側に前記陰極室と陽極室に各別に連通する一対の排水管路を有し、給水管路から供給される水をアルカリイオン水と酸性水に電解して前記一対の排水管路から排出する連続通水式の電解水生成装置において、浄水器の共通排水部から電解槽の各々の電極室に各別に接続された一対の給水支管と；浄水器上流側の給水管路から分岐され、前記電解槽のいずれか一方の電極室の出口側に連通するように配管された洗浄バイパスと；給水管路からの通水を前記電解槽の給水側と前記洗浄バイパス側へ択一的に開閉制御する第１の流路切換手段と；前記洗浄バイパスと、この洗浄バイパスが連通する電極室の排水管路出口側を択一的に開閉制御する第２の流路切換手段と；を具備することを特徴とする。
この場合に、前記第１の流路切換手段が前記第２の流路切換手段の一部または全部の機能を兼ねる構成にしてもよい。
【００１４】
また、上記第２の目的を達成するために、本願の請求項８の発明は、陰極室と陽極室に仕切った電解槽の一側に、浄水器を介装した給水管路を有するとともに、他側に前記陰極室と陽極室に各別に連通する一対の排水管路を有し、給水管路から供給される水をアルカリイオン水と酸性水に電解して前記一対の排水管路から排出する連続通水式の電解水生成装置において、浄水器の共通排水部から電解槽の各々の電極室に各別に接続された一対の給水支管と；浄水器上流側の給水管路と電解槽のいずれか一方の排水管路に関連して設けられ、洗浄時に給水管路からの通水を前記電解槽の一方の排水管路へ切り換える洗浄時流路切換手段と；を具備することを特徴とする。
【００１５】
さらに、上記第２の目的を達成するために、本願の請求項９の発明は、連続通水式の電解水生成装置において、前記洗浄時流路切換弁装置が、給水管路からの水の一部を電解槽の前記一方の排水管路の電解槽側へ通水し、一部をこの排水管路の吐水口側へ通水する分配機構を備えていることを特徴とする。
【００１６】
さらに、上記第２の目的を達成するために、本願の請求項１０の発明は、陰極室と陽極室に仕切った電解槽の一側に給水管路を有するとともに、他側に前記陰極室と陽極室に各別に連通する一対の排水管路を有し、給水管路から供給される水をアルカリイオン水と酸性水に電解して前記一対の排水管路から排出する連続通水式の電解水生成装置において、給水管路を電解槽の陰極室と陽極室に独立に連通する一対の給水支管に分岐し、陰極室に通ずる給水支管、又は前記給水管路と陰極室側給水支管、に吸着浄水器と濾過浄水器を上流、下流の位置関係で介装するとともに、吸着浄水器と濾過浄水器の間の給水支管と、陽極室に通ずる給水支管と、陽極室の排水管路の相互間に、洗浄時に、電解槽側のこれら２本の給水支管を給水管路側の給水支管から切り離して連通させ且つ給水管路に通ずる陽極室側給水支管と陽極室の排水管路を連通させる流路切換弁を設けたことを特徴とする。
【００１７】
この場合、流路切換弁を洗浄側に切換えると原水の全量が電解槽に流れるので濾過浄水器での圧力抵抗と相俟って洗浄水給水路の水圧が上昇し、該電極室の圧力が上昇し隔膜を破損するおそれがある。これを防止するために、請求項１１の発明は流路切換弁４６の下流側の陽極室側給水管路１５ｂと濾過浄水器の排出口の間に、該陽極室側給水管を流れる洗浄用酸性水の水圧が所定圧以上に上昇したときにこの洗浄用酸性水の一部を濾過浄水器内のミクロフイルタを迂回して排出口へ流す一方通行の迂回洗浄回路を設けたことを特徴とする。
【００１８】
さらに、上記第２の目的を達成するために、本願の請求項１２の発明は、陰極室と陽極室に仕切った電解槽の一側に給水管路を有するとともに、他側に前記陰極室と陽極室に各別に連通する一対の排水管路を有し、給水管路から供給される水をアルカリイオン水と酸性水に電解して前記一対の排水管路から排出する連続通水式の電解水生成装置において、給水管路に吸着浄水器と濾過浄水器を上流、下流の位置関係で配置し、濾過浄水器の下流側給水管路を一対の給水支管に分岐して電解槽の各電極室に独立に連通させるとともに、陽極室に通ずる側の給水支管から前記濾過浄水器の給水側に、洗浄用管路を配管し、前記陽極室側給水支管と洗浄用管路の相互間に流路切換機構を設けたことを特徴とする。
【００１９】
さらに、上記第２の目的を達成するために、本願の請求項１３の発明は、前記装置において、陰極室に通ずる給水支管から水抜き管路を分岐させ、この水抜き管路と前記給水管路の相互間に、給水管路の給水時の水圧で水抜き管路を閉じ、給水停止時の水圧で水抜き管路を開く水抜きバルブを設けたことを特徴とする。
【００２０】
本発明の上記装置は、さらに好ましくは、洗浄・殺菌時に、電解槽の出口側、すなわち、排水管路から洗浄水が給水される側の前記電極室の電極の極性を陽極に保持または切換えて電解槽での洗浄・殺菌電解を可能にする電気制御装置を具備している。
【００２１】
本発明の上記装置はさらに、前記洗浄バイパスや前記洗浄時流路切換弁装置に、電解槽への流量絞り効果をもたらす流量絞り機構を設け、洗浄・殺菌電解中の電解水のｐＨを更に下げたり、次亜塩素酸濃度が高くなるようにしてもよい。
【００２２】
上記第３の目的を達成するために、本願の請求項１６の流路切換弁装置の発明は、給水管路が接続される給水入口と、浄水器への給水管路が接続される給水出口と、電解槽の一方の排水管路に連通する洗浄水出口と、電解槽の前記一方の排水管路の排水部へ接続される排水出口を有するバルブケーシングと；バルブケーシング内を移動して前記給水入口から給水出口への通水路と前記給水入口から洗浄水出口及び排水出口への通水路とを択一的に開成する弁体と；を具備し、該弁体は、給水入口から洗浄水出口及び排水出口への通水路が開成したときに、給水入口から導入される水の一部を排水出口へ排水し、残りの水を洗浄水出口から排出する絞り部を具備していることを特徴とする。
【００２３】
【発明の実施の形態】
本発明は、給水管路から供給される水を陰極室と陽極室を有する電解槽で電解し、電解によって生成されたアルカリ水と酸性水を一対の排水管路から各別に排出する連続通水式電解水生成装置の洗浄・殺菌方法及びこの方法を実施するための構造を備えた連続通水式の電解水生成装置に関するもので、この方法の基本的な構成は、洗浄の際に、給水管路から電解槽入口への給水を抑制して電解槽の一方の電極室の排水管路から水道水などの洗浄水を給水し、該一方の電極室を逆流する洗浄水を、好ましくは電解により次亜塩素酸殺菌水に生成して、該一方の電極室から直接又は給水側の管路を介して他方の電極室へ通水しながら該他方の電極室の排水管路から排水するものである。
【００２４】
洗浄水を一方の電極室から電解槽の給水側の管路を介して他方の電極室を通水する手段には、一方の電極室の給水支管から逆流させた洗浄水を、ミクロフイルタなどの濾過浄水器出口側の共通排水部を通して他方の電極室の給水支管に通水する方法と、一方の電極室の給水支管から逆流させた洗浄水を濾過浄水器の濾過材内部を通過させて他方の電極の給水支管に通水する方法に大別される。
【００２５】
以下、図面を参照して本発明の実施の形態を更に詳細に説明する。
連続通水式電解水生成装置１は、対向配置した一対の電極２、３（図の実施例では陰極２と陽極３）間を電解用隔膜４で一対の電極室５、６（陰極室５と陽極室６）に仕切った有隔膜電解槽７を有し、この電解槽７の給水側に給水管路８を接続するとともに、電解槽７の排水側に陰極室５と陽極室６に各別（独立）に連通する一対の排水管路９、１０を接続してなり、通常のアルカリイオン水生成運転においては、給水管路８から通水した水道水などの原水、あるいは必要に応じてミネラル分等を補給した水を電解槽７で電解し、陰極室５で生成されるアルカリイオン水を排水管路９から取水し、陽極室６に生成される酸性水を排水管路１０からドレン１１へ捨てるようになっている。
電解のＯＮ−ＯＦＦ信号、即ち電極への電圧の印加は、例えば、給水管路８その他の通水路に介装した流量計２５あるいはフロースイッチからの信号で制御してもよい。
【００２６】
本発明の連続通水式電解水生成装置１は、活性炭、ミクロフィルター等を充填した浄水器１２を給水管路８に介装するとともに、浄水器１２の出口側共通排水部１３から電解槽７の前記陰極室５と陽極室６に各別に連通する一対の給水支管１４、１５を配管し、浄水器１２で浄化した水を電解槽７に供給して電解するようになっている。特に、本発明は、活性炭など、塩素を除去する濾過材を含む浄水器を使用する装置に有用である。
【００２７】
本発明による連続通水式電解水生成装置の洗浄・殺菌方法は、電解水生成装置１の給水管路８から電解槽７の入口への給水を抑制し、例えば給水管路８からの水道水などの洗浄用の水を電解槽７の一方の電極室出口から給水し、この電極室を逆流させた供給水を、浄水器１２の共通排水部１３を経由する一対の給水支管１４、１５を介して電解槽７の他方の電極室へ通水しながら該他方の電極室の排水管路から排水し、これにより、浄水器１２を経由しない水、すなわち、塩素が除去されていない殺菌力のある水を浄水器１２の共通排水部１３から下流側の給水支管１４、１５、電解槽７及び排水管路を通水させて洗浄・殺菌するものである。
【００２８】
また、本発明による上記電解水生成装置の他の洗浄・殺菌方法は、電解水生成装置１の給水管路８から電解槽７の入口への給水を抑制し、給水管路８からの水を管路を通して電解槽７の一方の電極室出口から給水し、この電極室を逆流させた供給水を、浄水器１２の共通排水部１３を経由する一対の給水支管１４、１５を介して電解槽７の他方の電極室へ通水しながら該他方の電極室の排水管路から排水する洗浄水回路を開成するとともに、電解槽７の出口側から給水される電極室の電極を陽極にして電解槽を通る水を電解することにより、該陽極電極室に次亜塩素酸殺菌水を生成し、この次亜塩素酸殺菌水が前記洗浄水回路を通る過程で、浄水器１２の共通排水部１３から下流側の給水支管１４、１５、電解槽７及び排水管路を次亜塩素酸殺菌水で洗浄・殺菌し、且つ、この次亜塩素酸水を陰極電極室に通す過程で中和して排出するようにしたものである。
【００２９】
洗浄・殺菌時の電解槽７への給水抑制は、浄水器１２本体の濾過材を通った水が電解槽７内に通水されないようにするためである。従って、ここで云う「給水抑制」は、給水を完全に止める場合に限らず、電解槽７の前記一方の配水管路出口側からの水圧よりも浄水器１２への給水圧を小さくする場合も含む。
【００３０】
つぎに、上記の洗浄・殺菌方法を実施する機構を備えた連続通水式電解水生成装置の実施形態について説明する。
図１ａ乃至図３ｂは本発明による連続通水式電解水生成装置の一実施形態を示すものでこの電解水生成装置１は、浄水器１２の上流側の給水管路８から洗浄バイパス１６を分岐させ、この洗浄バイパス１６を前記電解槽７の陰極室５又は陽極室６の出口側に連通するように配管してある。
図１ａ、図１ｂの実施例では、洗浄バイパス１６を陰極室５の排水管路９に接続し、排水管路９の一部（接続部上流側）を介して陰極室５に連通するようにしてある。
【００３１】
給水管路８と洗浄バイパス１６には、一方が開いているときに他方が閉じるように、給水管路８からの水が前記電解槽７の給水側と洗浄バイパス１６へ択一的に通水されるように開閉制御する第１の流路切換手段１７が設けられている。図の実施例では、流路切換手段１７として洗浄バイパス１６の分岐点に設けた三方弁を例示しているが、これに限らず、分岐点下流側の給水管路８のバイパス分岐点下流側と洗浄バイパス１６に一対の開閉弁装置を設け、交互に択一的に開閉するようにした流路切換手段でもよく、その他、電解槽７と洗浄バイパス１６への通水を択一的に切換える流路切換機能であれば他のいかなる構成のものでもよい
。
【００３２】
他方、洗浄バイパス１６と排水管路９には、洗浄バイパス１６から電極室５への給水回路と排水管路９からの排水回路を択一的に開閉制御する第２の流路切換手段１８が設けられている。
【００３３】
図１ａ乃至図３ｂの実施例の前記第２の流路切換手段１８は、洗浄バイパス１６と排水管路９の接続部に設けたチェックバルブで構成されており、通常はばね２０ｂに付勢された弁体２０ａで洗浄バイパス１６側の弁座を閉じるとともに 、排水管路９の排水路を開き、洗浄バイパス１６に水が通水されると水圧で弁体２０ａをばね２０ｂに抗して排水管路９の下流側弁座に押して付けることにより、洗浄バイパス１６が開くとともに、排水管路９からの排水が阻止されるようになっている。
【００３４】
但し、第２流路切換手段１８は上記のようなチェックバルブに限らず、洗浄バイパス１６と、該排水管路９のバイパス接続部下流側に設けた一対の、好ましくは電動開閉弁（図示せず）で構成してもよい。要するに、第２流路切換手段は、洗浄バイパス１６から電解槽７の一方の電極室５への給水と、該電解槽７の排水管路９からの排水を択一的に行うことができる構成であればよいので、その他の構造、例えば排水管路９のバイパス接続部下流側のみに設けた開閉弁と前記第１の流路切換手段の組合せで同じ目的を達成することも可能であり、さらにはバイパス１６を接続した排水管路出口先端を高い位置に設けた場合は第１流路切換手段で第２流路切換手段を兼用することもできる。
【００３５】
上記の構成により、図１ａ、図１ｂの実施形態の電解水生成装置１は、洗浄に際し、給水管路８の第１流路切換手段１７を洗浄バイパス１６側に開き、排水管路９側の第２流路切換手段１８を洗浄バイパス１６側に開くと、給水管路８の水は矢印のように洗浄バイパス１６を介して電解槽７の一方の電極室５の排水側から導入され 、電極室５→給水支管１４→浄水器１２の共通排水部１３→給水支管１５→他方の電極室６→他方の排水管路１０を経由する洗浄・殺菌用水回路（以下、洗浄水回路）に沿って流れる。この洗浄・殺菌用水回路を流れる水は浄水器１２の下流側給水管路８から洗浄バイパス１６を介して供給される水、すなわち、浄水器１２によって塩素等が取り除かれていない水であるから、前記電極室５、給水支管１４、浄水器１２の共通排水部１３、給水支管１５及び他方の電極室６は塩素の殺菌力を保持している水によって洗浄・殺菌されることになる。
【００３６】
図２ａ乃至図３ｂは本発明の他の実施形態を示すもので、この電解水生成装置１は、図１の電解水生成装置１に、さらに、洗浄バイパス１６からの水が給水される側の電極室の電極の極性を陽極に保持または切換えて洗浄殺菌電解を可能にする電気制御装置１９を付加的に設けたものである。なお、各々の符号は図１と同じ部材を示している。
【００３７】
先ず、図２ａ、図２ｂの装置は、図２ｂに示すように、前記第１流路切換手段１７と第２流路切換手段１８により、給水管路が前記洗浄バイパス１６を介して電解槽７の一方の電極室５に連通させた状態で、洗浄バイパス１６からの水が給水される側の電極室５の電極の極性を陽極に保持または切換えて電解することにより、該電極室５に次亜塩素酸水を発生させるようになっている。
【００３８】
すなわち、この電気制御装置１９は、図２ａ、図２ｂのように洗浄バイパス１６からの水が陰極室５の出口側から導入されるようにしている場合は、図２のように、洗浄・殺菌電解時に陰極室５の電極２を陽極に転換し、逆に、洗浄バイパス１６からの水が陽極室６の出口側から導入されるようにした場合（図は省略）は陽極室６の電極を陽極に保持するように電気回路が構成されている。
電極２の陽極保持又は陽極転換は洗浄バイパス１６の通水と連動するスイッチ等で操作されるようにしてもよく、また、洗浄バイパス１６の通水の前又は後で他のスイッチで操作するようにしてもよい。
【００３９】
かくして、通常の電解水生成時は、図２ａのように給水管路８から電解槽７の給水側へ給水され電解槽７でアルカリ水と酸性水に電解され、一対の排水管路９
、１０から別々に排出される。
【００４０】
他方、洗浄時は、図２ｂのように給水管路８の第１流路切換手段１７を洗浄バイパス１６側に開き、排水管路９側の第２流路切換手段１８を洗浄バイパス１６側に開くと、給水管路８の水は矢印のように洗浄バイパス１６を介して電解槽７の一方の電極室５の排水側から導入され、電極室５→給水支管１５→浄水器１２の共通排水部１３→給水支管１４→他方の電極室６→他方の排水管路１０を経由する洗浄・殺菌用水回路（以下、洗浄水回路）が開成されるとともに、洗浄バイパス１６からの水が給水される電極室５の電極極性が陽極に切換えられて電解電圧が印加される。
【００４１】
従って、洗浄バイパス１６から電極室５に給水された水は、陽極室に切換わった電極室５で電解整水される。ここで整水された水は酸性水であるため電極室５及び電解隔膜４に付着しているカルシウムなどの析出物を溶かし、洗浄を行うとともに、水に含まれている塩素イオンの作用により次亜塩素酸を多く含む殺菌水になり、電極室５の殺菌がなされる。特に、洗浄・殺菌時に電解される水は、浄水器１２の上流側から供給される水、すなわち、塩素が除かれていない水であるため、陽極室に生成される電解水は、浄水器１２を通した水を電解したときに比較して次亜塩素酸が多く発生する。
【００４２】
電極室５の給水側から排出された次亜塩素酸殺菌水は給水支管１４、浄水器１２の共通排水部１３及び給水支管１５を通る過程でこれを洗浄・殺菌するとともに、陰極室に切換わった電極室６での電解により中和され、排水管路１０から排出される。
【００４３】
かくして、通常の電解整水時に陰極室であった電解槽７の電極室が酸性水で洗浄されるとともに、ここで生成される次亜塩素酸殺菌水で電解槽内及びその周辺の管路が殺菌される。
【００４４】
洗浄時の電解槽７の次亜塩素酸濃度を高くするために、洗浄バイパス１６に絞り弁２０等の給水量を抑制する手段を設け、給水量を少なくしてゆっくり電解するようにしてもよい。同じ目的で洗浄バイパス１６を給水管よりも細くしてもよく、さらには、通常のアルカリイオン水生成電解時よりも、洗浄・殺菌電解時の電解電流を多くしてもよい。
【００４５】
水道水などの原水には洗浄・殺菌電解時に次亜塩素酸を発生させるための塩素イオンが含まれているが、次亜塩素酸濃度を高めるために、必要により、洗浄バイパス１６に塩化ナトリウムなどの塩化物塩の添加手段を設けてもよい。
【００４６】
また、陰極室５に連通する給水支管１４にカルシウム等を供給するためのミネラル補給筒２２を設ける場合に、電極の極性が逆転してもミネラルが常に陰極室側に供給されるように、給水支管１４、１５に流路切換装置２３が設けられている。尚、図は省略したが、陽極室６に通ずる給水支管１５にも陽極室６に必要な薬液を添加するための薬液添加筒を設けてもよい。
【００４７】
次に、図３ａ、図３ｂの実施態様は、電解槽７の電極２、３に陰極・陽極両用に耐用できる電極、例えば、チタン材に白金、イリジウム等の白金属メッキを施した電極を用い、所定時間毎に電極の極性を変換して通常の電解を行う場合を示している。この種の装置では、極性が逆転しても、アルカリイオン水が常に同じ取水口から排出されるように排水管路９、１０に流路切換装置２１が設けられている。
【００４８】
図３ａ、図３ｂの実施態様は、洗浄・殺菌電解の際に、図３ｂのように、洗浄バイパス１６から排水管路９を介して電解槽７の電極室５に給水された水が流路切換装置２３を介して給水支管１５に流れるとともに、給水支管１４から流路切換装置２３を介して電極室６へ給水されて排水管路１０から排水される洗浄水回路が形成され、電極室５の電極２を陽極に転換して洗浄電解が行われるようにしたものである。
【００４９】
図１ａ乃至図２ａの実施態様は、いずれも洗浄バイパス１６を陰極室５の排水管路９に接続しているが、図３ａのように陽極室６の排水管路１０に接続してもよい。この場合に、図３ａの極性をそのままにして陽極室６で生成した次亜塩素酸殺菌水を給水支管１４、１５を通して陰極室５に通水して排水管路９から排水するようにしてもよいが、好ましくは、通常電解時の陰極室５内で洗浄・殺菌電解の次亜塩素酸殺菌水が生成されるようにするため、図３ｂのように、洗浄バイパス１６からの給水を流路切換装置２１を介して電極室５へ切換えるとともに、電極室６から排水される水を流路切換装置２１を介して排水管路９から排水されるように洗浄水回路を形成し、電極室５の電極２を陽極に転換して洗浄電解が行われるようにするのが望ましい。
尚、洗浄バイパス１６を排水管路１０に接続した場合は洗浄電解時にアルカリ水排水管路９の先端までが次亜塩素酸殺菌水で洗浄・殺菌される利点がある。
【００５０】
図の実施例では、いずれも、洗浄バイパス１６を排水管路９または１０を介して電解槽７の電極室５または６の出口側に連通させるようにしているが、電極室５または６の出口側に直接連通させるようにしてもよい。
【００５１】
図４ａ乃至図５ｂは本発明による連続通水式電解水生成装置の他の実施形態を示すもので、図１ａ乃至図３ｂの実施形態は、浄水器１２の上流側の給水管路８から電解槽７の一方の出口へ給水するために洗浄バイパス１６を設けているのに対し、図４ａ乃至図５ｂの装置１は、電解槽７のいずれか一方の排水管路９又は１０を利用し、給水管路８とこの排水管路９又は１０に関連して洗浄時流路切換弁装置２６を設け、この洗浄時流路弁装置２６を切り換えて給水管路８から電解槽７のいずれか一方の電極室の出口側に給水されるようになっている。
【００５２】
すなわち、図４ａ、図４ｂの実施例は、電解槽７のアルカリ水排水管路９と浄水器１２の上流側給水管路８に関連させて前記洗浄時流路切換弁装置２６を設けている。
この構成では、通常電解時は図４ａのように、給水管路８からの水は浄水器１２、給水支管１４、１５を介して電解槽７に給水され、アルカリ水と酸性水に電解され、アルカリ水はアルカリ水排水管路９を通して排出されるとともに、酸性水は酸性水排水管路１０からドレン１１へ排出される。
他方、洗浄・殺菌の際は、洗浄時流路切換弁装置２６の流路をアルカリ水排水管路９に切り換えると、給水管路８からの水はアルカリ水排水管路９を逆流して電解槽７の電極室５側の出口から給水され、電極室５から給水支管１４を逆流して浄水器１２へ流れるとともに、浄水器１２の共通排水部１３から給水支管１５を通って電解槽７の電極室６へ導入されて酸性水排水管路１０からドレン１１へ排水される洗浄水回路が開成される。かくして、給水管路８からの水が浄水器１２を迂回して上記洗浄水回路を通ることにより、該回路が塩素を含んだ水によって洗浄・殺菌される。
【００５３】
図５ａ、図５ｂの実施形態は、これとは逆に、電解槽７の酸性水排水管路１０と浄水器１２の上流側給水管路８に関連させて前記洗浄時流路切換弁装置２６を設けている。
この構成では、洗浄・殺菌の際は、図５ａの状態から図５ｂのように洗浄時流路切換弁装置２６の流路を酸性水排水管路１０に切り換えると、給水管路８からの水は酸性水排水管路１０を逆流して電解槽７の電極室６側の出口から給水され、電極室６から給水支管１５を逆流して浄水器１２へ流れるとともに、浄水器１２の共通排水部１３から給水支管１４を通って電解槽７の電極室５へ導入されてアルカリ水排水管路９から排水蛇口へ排水される洗浄水回路が開成される。かくして、給水管路８からの水が上記洗浄水回路を通ることにより、該回路が塩素を含んだ水によって洗浄・殺菌される。
【００５４】
図６及び図７は本発明による電解水生成装置のさらに他の実施形態を示すもので、このものは、浄水器１２の上流側の給水管路８と、電解槽７の排水管路９又は１０に関連して設けられる前記洗浄時流路切換弁装置２６が、排水管路９又は１０（図６、図７の場合はアルカリ水排水管路９）に給水される水の一部を該排水管路９又は１０の電解槽７側へ通水するとともに、残りの水をこの排水管路９又は１０の吐水口側へ通水する分配機構４４を備えている。
この分配機構４４は、好ましくは図６のように、排水管路吐水口側への通水路に絞り部４５を設け、これにより、電解槽７側への通水が保証され、且つ、必要量以上の水が吐水口から無駄に排出されないようにする。
【００５５】
すなわち、水道水は塩素を含み、それ自体が殺菌力をもつものであが、排水管路９又は１０に給水される水道水等の洗浄用水の全部を電解槽７側へ通水してしまうと、この排水管路の内、洗浄時流路切換弁装置２６よりも下流側の排水管路は全く洗浄・殺菌されないのに対し、図６、図７のように、水道水の一部が洗浄時流路切換弁装置２６よりも下流側の排水管路へながれるようにすることにより、排水管路の吐水口までが水道水などの洗浄用水で洗浄・殺菌されるようになる。
【００５６】
なお、洗浄時流路切換弁装置２６として、図６では切換弁を使用し、図７では分岐水栓を使用しているが、前記洗浄用水の給水分配機構４４はそのいずれにも適用できるものである。
【００５７】
図４ａ乃至図７の装置において，図１ａ乃至図３ｂの装置と同じ参照記号は同じ機能を有する部材を示している。例えば、洗浄水回路の水に次亜塩素酸を発生させて殺菌する場合は、洗浄・殺菌時に、電解槽７の出口側から給水される側の電極室の電極を陽極に保持又は切り換えて洗浄・殺菌用の電解がなされるように前記と同様の電気制御装置１９を設ける。
【００５８】
また、図５ａ、図５ｂのように、一対の排水管路９、１０に流路切換装置２１を設けると共に、給水支管１４、１５にも流路切換装置２３を設けてもよい。これら流路切換装置２１、２３の機能は図２ａ乃至図３ｂのものと同様であるので説明は省略する。
【００５９】
さらに、前記電気制御装置１９を設けた装置の場合は、洗浄水回路の給水量を制限して洗浄時の電解槽７の次亜塩素酸濃度を高くするために、前記洗浄時流路切換弁装置２６は、給水管路８を電解槽７の前記一方の排水管路へ接続する通水路にオリフイス、流量絞り弁、その他流量絞り効果をもたらす流量絞り機構２７を設けるのが望ましい。
【００６０】
図１ａ乃至図３ｂにおける第１流路切換手段１７及び第２流路切換手段１８の切り換え操作、図４ａ乃至図７における洗浄時流路切換弁装置２６の切換操作並びに、洗浄電解の操作は手動でも電動でもよい。例えば、通常の電解整水をしていない夜間等に手動またはタイマ等の自動手段で上記洗浄電解による洗浄・殺菌が行われるようにしてもよいし、通常の電解整水時間を積算して設定積算値に達したときに自動的に洗浄電解がなされるようにしたり、あるいは、洗浄電解の警告をしたりするようにしてもよい。
【００６１】
図２ａ乃至図７の実施形態は洗浄・殺菌の時だけ電極の極性を切り換えればよいので、通常電解の陰極にステンレスなどの比較的安価な電極材料を使用できるが、ステンレス電極を陽極に切り換えて洗浄・殺菌電解をした場合は、次亜塩素酸の発生が少ないので、洗浄・殺菌電解時に次亜塩素酸の発生を多くしたいときは、洗浄・殺菌電解時に陽極となる電極の材料はチタン材に白金属メッキを施したもの、例えば、チタン材に白金とイリジウムをコーティングしたものを用いるのが望ましい。
【００６２】
洗浄・殺菌電解による洗浄・殺菌は予め設定した所定の時間行われるようにし、洗浄・殺菌中は表示灯などで警告されるようにする。
【００６３】
さらには、洗浄電解による殺菌・制菌を行った後は通常電解として使用する前の所定時間、水を通水して次亜塩素酸殺菌水を排水するとともに、この間は警告をしたり、排水流路をドレン側に切換えて、アルカリ水取水口から吐水されないようにするしてもよい。
【００６４】
以上の説明は、本発明の実施形態を例示したものでこれに限定されるものではない。
例えば、洗浄・殺菌時に水が給水される管路にミクロフイルタや次亜塩素酸発生器を介装してもよい。
また、浄水器１２はフイルタあるいはミクロフイルタを内蔵しているものにかぎらず、浄水器１２とフイルタあるいはミクロフイルタが別体になっていてもよい。
【００６５】
図８ａ乃至図８ｄは図６、図７の装置に使用される洗浄時流路切換弁装置２６の好ましい実施形態を示すもので、この洗浄時流路切換弁装置２６は、中空管状のバルブケーシング２８の一側に、浄水器１２への給水出口２９を形成するとともに、他側に、電解槽７の一方の排水管路排水部に連通する排水出口３０を形成してあり、このバルブケーシング２８の前記給水出口２９と排水出口３０の間に給水入口３１を設けてある。また、バルブケーシング２８の前記排水出口３０と給水入口３１の間に、電解槽７の一方の排水管路に接続される洗浄水出口３２が設けられている。
【００６６】
バルブケーシング２８の中空内部通水路には、給水入口３１と前記給水出口２９の間に弁座３３が設けられており、また、給水入口３１と前記洗浄水出口３２の間に別の弁座３４が設けられている。
【００６７】
弁座３３、３４の間に弁体３５が配設されており、この弁体３５はバルブケーシング２８の外部から軸方向に液密且つ摺動自在に挿入された操作ロッド３６に固定されている。また、操作ロッド３６はバルブケーシング２８の外部に突出させた先端部をモータなどの駆動装置３７に連結して往復移動されるようになっており、操作ロッド３６の往復ストロークにより、弁座３３と弁座３４を選択的に開閉するように組付けられている。
【００６８】
弁体３５はその先端側に、給水入口３１から洗浄水出口３２及び排水出口３０への通水路が開成したときに、給水入口３１から導入される水の一部を排水出口３０へ排水し、残りの水を洗浄水出口３２から排水する流量絞り部３８を一体に備えている。
【００６９】
図８ａ乃至図８ｄの流量絞り部３８は、バルブケーシング２８の内壁面に当接して排水出口３０への通水路を閉鎖する閉鎖部材３９を前部外周に形成した先端開口の筒体４０を有し、この筒体４０の後部外周に洗浄水出口３２への通水路を形成する切欠き板４１を形成するとともに、この切欠き板４１の後方から中空内部へ貫通して筒体４０の内部を介して排水出口３０と連通する通水孔４２を形成した構成になっている。
なお、バルブケーシング２８の排水出口３０の後方には排水出口３０側への排水を許容し、排水出口３０側からの水の逆流を規制する可撓性材料の逆止弁４３が配設されている。
【００７０】
かくして、図６ａのようにアルカリ水を生成する通常電解時は、給水入口３１から導入された水は給水出口２９から浄水器へ給水される。
他方、洗浄・殺菌時に図６ｃの状態に弁体３５が移動すると、給水入口３１から導入された水の一部は絞り部材３８の通水孔４２を通って排水出口３０から排出され、残りが絞り部材３８の切欠き板４１を通って洗浄水出口３２から排出される。従って、洗浄殺菌時に洗浄水出口３２から電解槽７の一方の電極室へ給水される流量は絞り部材３８によって減量されたものになる。
【００７１】
図９ａ、図９ｂは本発明のさらに他の実施形態を示すもので、この連続通水式電解水生成装置１は、給水管路８を電解槽７の陰極室５と陽極室６に独立に連通する一対の給水支管１４、１５に分岐し、陰極室５に通ずる給水支管１４に活性炭などの吸着浄水器１２ａを介装するとともに、その下流側にミクロフイルタなどの濾過浄水器１２ｂを介装してある。図は省略したが、上記の変形例として、給水管路８に吸着浄水器１２ａを設け、陰極室側給水支管１４に濾過浄水器１２ｂを設けた構成でもよい。このような電解水生成装置において、前記吸着浄水器１２ａと濾過浄水器１２ｂの間の管路と、前記陽極室６側の給水支管１５と、前記陽極室６の排水管路１０の相互間に、洗浄時に、電解槽７側のこれら２本の給水支管１４ｂ、１５ｂを給水管路８側の給水支管１４ａ、１５ａから切り離して連通させ、且つ、給水管路８に通ずる陽極室側給水支管１５ａと陽極室側排水管路１０を連通させる流路切換弁４６が設けられている。
【００７２】
上記構成により、通常の電解水生成運転時は、図９ａに示すように、給水管８の給水支管１４から供給された原水は、吸着浄水器１２ａ、流路切換弁４６の通常電解時流路、濾過浄水器１２ｂ、薬液添加筒２２を通って電解槽７の陰極室５に給水されるとともに、給水支管１５から供給された原水は流路切換弁４６の通常電解時流路を通って電解槽７の陽極室６に給水される。
かくして、電解電圧の印加により陰極室５にアルカリ水が生成されて排水管路９から排出されるとともに、陽極室６には酸性水が生成され、排水管路１０から流路切換弁４６の通常電解時流路を通してドレン１１へ排出される。
【００７３】
洗浄に際しては、図９ｂのように、流路切換弁４６を洗浄回路側に切換えると、電解槽７の陰極室５に接続されている給水管路１４ｂと陽極室６に接続されている給水管路１５ｂが流路切換弁４６の切換通路を介して、給水管路８側の給水支管１４ａ、１５ａからそれぞれ切り離されて相互に連通する。
他方、給水管路８側の給水支管１５ａと陽極室６側の排水管路１０は流路切換弁４６の切換通路を介して連通する。
【００７４】
かくして、流路切換弁４６を上記の洗浄回路側に切換えると給水管路８から給水支管１５ａ→流路切換弁４６→排水管路１０→陽極室６→給水支管１５ｂ→流路切換弁４６→給水支管１４ｂ→濾過浄水器１２ｂ→陰極室５→排水管路９への洗浄回路が開閉され、この洗浄回路に給水管路８から水（洗浄水）を給水することにより電解槽７、濾過浄水器１２ｂを含む洗浄回路全体が洗浄される。
【００７５】
また、この洗浄時に、（必要に応じて塩化ナトリウムなどの塩化物塩を洗浄水に添加して）電解槽７の電極２、３に電解電圧を印加すると陽極室６で次亜塩素酸水が生成され、前記洗浄回路の陽極室６及びその下流側洗浄回路は次亜塩素酸水で洗浄・殺菌される。
【００７６】
尚、特に次亜塩素酸水を生成して殺菌する場合は洗浄水の流量を絞り、陽極室６で充分な濃度の次亜塩素酸水が生成させるのが有利である。このため、図９ｂの実施例では流路切換弁４６の給水支管１５ａと排水管路１０を連通させる流路に絞り弁２４を設けている。
さらに、図９ｂのように洗浄時の給水流量の一部を洗浄水として使用し、一部をドレンへ排水するようにしてもよい。この場合は、ドレンへの排水路４７に絞り弁４８を設ける。
【００７７】
図９ｃは、図９ａ及び図９ｂの装置にさらに改良を加えたもので、この実施例は、流路切換弁４６から陽極室６に接続されている給水管路１５ｂと濾過浄水器１２ｂの排出口６３の間に、洗浄時に該陽極室側給水管路１５ｂの水圧が所定圧以上に上昇したときに、この給水管路１５ｂを流れる洗浄用電解酸性水の一部を濾過浄水器１２ｂのミクロフイルタ６４を迂回して排出口６３に流す一方通行の迂回洗浄回路６５を設けたものである。
【００７８】
給水管路１５ｂは、図９ｂ、図９ｃのように流路切換弁４６を洗浄回路に切換えたときに、濾過浄水器１２ｂへの給水路となるものであるが、流路切換弁４６を洗浄回路に切換えると陰極室５への原水給水が停止され、原水給水の全量もしくはほとんどが電解槽３の陽極室６を逆流して給水管路１５ｂへ流れ、給水管路１５ｂの水圧が上昇する。他方、濾過浄水器１２は通常のアルカリ水生成電解時には原水の一部が流入し他は陽極室６へ給水されるようになっているので洗浄時に水圧が上昇した排水管路１０の洗浄水の全量が濾過浄水器１２ｂに流入するとミクロフイルタ６４の抵抗で陽極室６の水圧が上昇し、隔膜４が破損するおそれがある。特に、ミクロフイルタ６４に目詰りが生ずるとこの傾向が高まる。
迂回洗浄回路６５はこれを防止するための圧力抜き回路であり、洗浄回路を開成して電解槽７及びその先の給水管路１５ｂの水圧が上昇すると洗浄水の一部が迂回洗浄水回路６５からばね６６に付勢されている逆止弁６７を開いて濾過浄水器１２ｂへ流れ、該浄水器１２ｂのミクロフイルタ６４を迂回して排出口６３へ流れる。従って、電解槽７の隔膜４には過度の水圧がかからず、しかも、濾過浄水器１２ｂの排出側及びその下流側水回路は洗浄用酸性水（次亜塩素酸水）の全量で洗浄される。
【００７９】
図１０ａ、図１０ｂは流路切換弁４６の一例を示すもので、図１０ａは流路切換弁４６の前記の通常電解時の水回路を示し、図１０ｂは洗浄時の水回路を示している。この実施例ではバルブケーシング４９の給水支管１５ａ及び排水管路１０への各通口と弁体５０の位置関係で前記絞り弁２４、４８の機能を果すようにしてある。
【００８０】
図１１ａ、図１１ｂは本発明のさらに別の実施形態を示すもので、この連続通水式電解水生成装置は給水管路８に吸着浄水器１２ａと濾過浄水器１２ｂを上流、下流の位置関係で配置し、濾過浄水器１２ｂの下流側給水管路８を陰極室５への給水支管１４と陽極室への給水支管１５に分岐して電解槽７への各電極室５、６に独立に連通させるとともに、陽極室６に通じる給水支管１５から前記濾過浄水器１２ｂの給水側に洗浄用管路５１を配管し、前記の陽極室側給水支管１５と洗浄管路５１の相互間に給水支管１５と洗浄管路５１を選択的に開閉させる、例えば三方弁などの流路切換機構５２を設けたものである。
【００８１】
この装置は流路切換機構５２を給水支管１５側に開くと図１１ａのように通常の電解水生成の水回路が形成され、他方、流路切換機構５２を洗浄管路５１側に開くと、図１１ｂに示すように、陽極室６に通ずる給水支管１５と陰極室５側の給水支管１４が洗浄管路５１と濾過浄水器１２ａを通して連通し、排水管路１０から陽極室６→洗浄管路５１→濾過浄水器１２ｂ→給水管路８→給水支管１４→陰極室５→排水管路９に至る洗浄回路が形成される。
かくして、この洗浄回路に洗浄水を前記の方向に通水することにより洗浄がなされるとともに、このとき電解電圧を印加すると陽極室６に次亜塩素酸殺菌水が生成され、洗浄回路の洗浄・殺菌がなされる。
【００８２】
尚、図９ａ、図９ｂの装置に示すように、陰極室５に通ずる給水支管１４ｂから水抜き管路５３を分岐させ、この水抜き管路５３と前記給水管路８の相互間に、給水管路８の給水時の水圧で水抜き管路５３を閉じ、給水停止時の水圧で水抜き管路５３を開く水抜きバルブ５４を設け、給水管路８の開閉弁５５を開いて給水したときは水抜きバルブ５４が閉じ、給水を停止させると水抜きバルブが開き、装置内の残水が排水されるようにしてある。
この水抜き機構は、給水を止め、電解槽７の電極室５、６の極性を転換して電解槽の水を抜きながら逆電洗浄をする際に使用するもので、図は省略してあるが、このような水抜き機構は本発明の他の装置にも同様に設けることができる。
【００８３】
図１２ａ、図１２ｂは前記水抜きバルブ５４の一例を示すもので、バルブケーシング５６内を、ダイアフラム５７によって給水管路８側のチヤンバ５８と水抜き管路５３側チヤンバ５９に仕切るとともに、水抜き管路側チヤンバ５９に、好ましくは弁座孔６０’を有する弁座６０を形成し、ダイアフラム５７にこの弁座孔６０’を開閉する弁体６１を取付け、ばね６２によりダイアフラム５７を給水管路側チヤンバ５８に付勢させた構造になっている。
【００８４】
上記の構成により、給水管路８に水を通水すると、チヤンバ５８の水圧上昇によりダイアフラム５７及び弁体６１がチヤンバ５９側に押され、弁体６１によって水抜き管路５３の弁座孔６０’が閉じられる。従って、通常の電解運転中は水抜き管路５３が閉じた状態で電解槽７に給水され、電解水の生成が行われる。
他方、給水管路８への給水を停止すると、図１２ｂのようにチヤンバ５８の圧力が減少し、ばね６２の復元力によりダイアフラム５７がチヤンバ５８側に押し戻され、これに伴って弁体６１が弁座孔６０’を開く。かくして水抜き管路５３が開成され、電解水生成装置の水抜きがなされる。
尚、図の実施例では弁座孔６０’に所定の長さＬを持たせ、これにより、給水管路８からの給水を停止してから水抜き管路５３が開くまでに所定の間がとれるようにしてある。この構成により、電解槽の水を抜きながら逆電洗浄を行う際に、電解槽７に水が残っている時間を長くし、逆電洗浄時間を充分にとることができる。
【００８５】
図は省略してあるが、図１１ａ乃至図１２ｂの実施例の電解水生成装置が、所定時間毎に電極の極性を転換して電解水を生成する逆電式の電解水生成装置である場合は、図１ａと同様に、洗浄時には排水管路から洗浄水を給水する側の電極室を陽極側に切換える電気制御装置１９を設ける。
【００８６】
【効果】
本発明は、吸着浄水器を迂回した水、すなわち、塩素が除去されていない水を電解槽の一方の電極室から導入し、一方の給水支管−浄水器の共通排水部または内部−他方の給水支管−他方の電極室−の順に通水して排出するので浄水器の下流側水回路全体を塩素を含む水で洗浄・殺菌することができる。
【００８７】
また、電解洗浄の際に、電解槽の一方の電極室の出口側から給水した水を該電極室の電極を陽極にして電解することにより、該電極室に酸性水が生成され、電極室の電極や電解膜に付着していたカルシウム等の析出物が洗浄される。
また、この時に陽極室に生成される電解生成水は殺菌力の強い次亜塩素酸を多く含む殺菌水であり、この水が給水管路等の周辺通水路及び他方の電極室を通って排水されることにより、電解槽及びその周辺管路（洗浄水回路）特に、ミネラル補給時に外気に触れやすく、且つ、浄水器によって塩素が除去されて雑菌が繁殖しやすくなっている給水支管が前記次亜塩素酸殺菌水で殺菌・制菌される。従って、従来の装置に比較して洗浄・殺菌効果が著しく向上するとともに、一連の作用で洗浄と殺菌・制菌が同時になされる。
【００８８】
洗浄・殺菌電解時の陽極室で生成された酸性水が陰極室に導入されることにより、陰極室の水は中和され、中性に近い水になる。従って、従来のように、単なる逆電洗浄では、電極室の一方の水が酸性になっても他方の電極室の水がアルカリ性であるため隔膜表面の酸性水は中和されてしまいカルシウム等の溶解力が低下してしまったが、本発明ではアルカリ水が中和されるのでこの問題が合理的に解消される。
【００８９】
また、これを反面から見ると、陽極室で生成された次亜塩素酸水は陰極室を通る過程で中和されて排水されるので害がなく排水周辺の金属器具を腐食させない
。
【００９０】
従来のいわゆる逆電電解は、陰極・陽極両用のチタン白金メッキ電極などの高価な電極を必要とし、また、給・排水管路の流路切換弁が必要であったが、本発明は陰極をステンレスとし、陽極をフェライト等とする通常電解時の安価な電極で洗浄電解をすることができ、コストダウンをはかることができる。
【００９１】
洗浄時流路切換弁装置に分配機構を設けたことにより、洗浄水を給水する排水管路はその吐水口まで塩素を含む水道水で洗浄されるようになる。
【００９２】
陽極室側給水管路から濾過浄水器の排出口へミクロフイルタを通さない迂回洗浄水回路を設けることによって電解槽の隔膜の破損が防止される。

Water supplemented with minerals and the like is electrolyzed in the electrolytic cell 7, alkaline ionized water generated in the cathode chamber 5 is taken from the drain pipe 9, and acidic water generated in the anode chamber 6 is drained from the drain pipe 10. 11 is thrown away.
The electrolysis ON-OFF signal, that is, the application of a voltage to the electrode may be controlled by a signal from the flow meter 25 or the flow switch interposed in the water supply pipe 8 or other water passage, for example.
[0026]
The continuous water electrolyzed water generating device 1 according to the present invention includes a water purifier 12 filled with activated carbon, a microfilter, and the like interposed in a water supply pipe 8, and from the outlet side common drainage portion 13 of the water purifier 12 to the electrolytic cell 7. A pair of water supply branch pipes 14 and 15 communicating with the cathode chamber 5 and the anode chamber 6 are separately provided, and the water purified by the water purifier 12 is supplied to the electrolytic cell 7 for electrolysis. In particular, the present invention is useful for an apparatus that uses a water purifier including a filter medium that removes chlorine, such as activated carbon.
[0027]
The method for cleaning and sterilizing a continuous water electrolyzed water generating device according to the present invention suppresses water supply from the water supply line 8 of the electrolyzed water generating device 1 to the inlet of the electrolytic cell 7, for example, tap water from the water supply line 8. For example, a pair of water supply branch pipes 14 and 15 passing through the common drainage portion 13 of the water purifier 12 are supplied to the water for cleaning such as from the outlet of one electrode chamber of the electrolytic cell 7 and the reverse flow of the electrode chamber is performed. The water is drained from the drain pipe of the other electrode chamber while passing the water through the other electrode chamber of the electrolytic cell 7, and thus, the water that does not pass through the water purifier 12, that is, the sterilizing power of which chlorine is not removed. A certain amount of water is washed and sterilized by passing water from the common drainage section 13 of the water purifier 12 to the downstream water supply branch pipes 14 and 15, the electrolytic bath 7 and the drainage pipe.
[0028]
In addition, another method for cleaning and sterilizing the electrolyzed water generating apparatus according to the present invention suppresses water supply from the water supply line 8 of the electrolyzed water generating apparatus 1 to the inlet of the electrolysis tank 7, and supplies water from the water supply line 8. Water is supplied from the outlet of one electrode chamber of the electrolytic cell 7 through the pipe line, and the supplied water that has flowed backward through the electrode chamber is supplied to the electrolytic cell via a pair of water supply branch pipes 14 and 15 passing through the common drainage part 13 of the water purifier 12. 7, a washing water circuit for draining water from the drain pipe of the other electrode chamber while opening water to the other electrode chamber of the other electrode chamber 7 is opened, and electrolysis is performed using the electrode in the electrode chamber supplied from the outlet side of the electrolytic cell 7 as an anode. By electrolyzing the water passing through the tank, hypochlorous acid sterilized water is generated in the anode electrode chamber, and in the process that the hypochlorous acid sterilized water passes through the washing water circuit, the common drain part 13 of the water purifier 12 is used. Hypochlorous acid in the water supply branch pipes 14 and 15, the electrolytic cell 7, and the drain pipe on the downstream side Washed and sterilizing with bacteriostatic water, and is obtained by to discharge and neutralization in the process of passing the hypochlorous acid solution in the cathode electrode compartment.
[0029]
The suppression of water supply to the electrolytic cell 7 at the time of washing and sterilization is to prevent water that has passed through the filter medium of the water purifier 12 body from flowing into the electrolytic cell 7. Therefore, the “water supply suppression” referred to here is not limited to completely stopping the water supply, but may be a case where the water supply pressure to the water purifier 12 is made smaller than the water pressure from the one water distribution pipe outlet side of the electrolytic cell 7. Including.
[0030]
Next, an embodiment of the continuous water electrolyzed water generating apparatus provided with a mechanism for performing the above-described cleaning / sterilizing method will be described.
FIGS. 1 a to 3 b show an embodiment of a continuous water electrolyzed water generating device according to the present invention. This electrolyzed water generating device 1 branches a washing bypass 16 from a water supply pipe 8 upstream of a water purifier 12. The cleaning bypass 16 is piped so as to communicate with the cathode chamber 5 or the anode chamber 6 of the electrolytic cell 7.
In the embodiment of FIGS. 1a and 1b, the cleaning bypass 16 is connected to the drain line 9 of the cathode chamber 5, and communicates with the cathode chamber 5 through a part of the drain line 9 (upstream of the connecting portion). It is.
[0031]
The water from the water supply line 8 is selectively passed to the water supply side of the electrolytic cell 7 and the cleaning bypass 16 so that when the one is open, the other is closed. Thus, first flow path switching means 17 is provided for controlling opening and closing. In the illustrated embodiment, a three-way valve provided at the branch point of the cleaning bypass 16 is illustrated as the flow path switching means 17, but is not limited to this, and the bypass branch point downstream of the water supply pipe line 8 on the downstream side of the branch point. Further, a flow path switching means provided with a pair of on-off valve devices in the cleaning bypass 16 and alternately opening and closing may be used, or the water flow to the electrolytic cell 7 and the cleaning bypass 16 is switched alternatively. Any other configuration may be used as long as it is a channel switching function.
.
[0032]
On the other hand, the cleaning bypass 16 and the drain pipe 9 are provided with second flow path switching means 18 that selectively opens and closes the water supply circuit from the cleaning bypass 16 to the electrode chamber 5 and the drain circuit from the drain pipe 9. Is provided.
[0033]
The second flow path switching means 18 in the embodiment of FIGS. 1a to 3b is composed of a check valve provided at the connecting portion between the cleaning bypass 16 and the drain pipe 9 and is normally biased by a spring 20b. When the valve seat 20a closes the valve seat on the side of the cleaning bypass 16 and opens the drainage passage 9 and when water is passed through the cleaning bypass 16, the valve body 20a is drained against the spring 20b by water pressure. By pressing against the downstream valve seat of the conduit 9, the cleaning bypass 16 is opened and drainage from the drain conduit 9 is prevented.
[0034]
However, the second flow path switching means 18 is not limited to the check valve as described above, but a pair of preferably on-off valves (not shown) provided on the downstream side of the bypass connection portion of the cleaning bypass 16 and the drain pipe 9. May be configured. In short, the second flow path switching means can selectively perform water supply from the washing bypass 16 to one electrode chamber 5 of the electrolytic cell 7 and drainage from the drain line 9 of the electrolytic cell 7. Therefore, it is also possible to achieve the same purpose with a combination of other structures, for example, an on-off valve provided only on the downstream side of the bypass connection portion of the drain pipe 9 and the first flow path switching means, Furthermore, when the drain pipe outlet end connected to the bypass 16 is provided at a high position, the first flow path switching means can also serve as the second flow path switching means.
[0035]
With the above configuration, the electrolyzed water generating device 1 according to the embodiment of FIGS. 1a and 1b opens the first flow path switching means 17 of the water supply line 8 to the cleaning bypass 16 side during the cleaning, When the second flow path switching means 18 is opened to the cleaning bypass 16 side, the water in the water supply pipe 8 is introduced from the drain side of one electrode chamber 5 of the electrolytic cell 7 through the cleaning bypass 16 as indicated by the arrow. Along with a cleaning / sterilizing water circuit (hereinafter referred to as a cleaning water circuit) passing through the chamber 5 → the water supply branch 14 → the common drain part 13 of the water purifier 12 → the water supply branch 15 → the other electrode chamber 6 → the other drain pipe 10 Flowing. Since the water flowing through the washing / sterilizing water circuit is water supplied from the downstream water supply pipe 8 of the water purifier 12 through the washing bypass 16, that is, water from which chlorine or the like has not been removed by the water purifier 12, The electrode chamber 5, the water supply branch 14, the common drainage 13 of the water purifier 12, the water supply branch 15 and the other electrode chamber 6 are cleaned and sterilized with water holding the sterilizing power of chlorine.
[0036]
FIGS. 2a to 3b show another embodiment of the present invention. This electrolyzed water generating apparatus 1 is provided on the side where water from the cleaning bypass 16 is further supplied to the electrolyzed water generating apparatus 1 of FIG. An electric control device 19 is additionally provided to enable cleaning and sterilization electrolysis by maintaining or switching the polarity of the electrode in the electrode chamber to the anode. In addition, each code | symbol has shown the same member as FIG.
[0037]
First, as shown in FIG. 2b, the apparatus shown in FIGS. 2a and 2b is configured such that the water supply pipe line is connected to the electrolytic cell 7 via the cleaning bypass 16 by the first flow path switching means 17 and the second flow path switching means 18. In the state where the electrode chamber 5 is in communication with the electrode chamber 5, the polarity of the electrode in the electrode chamber 5 on the side to which water from the cleaning bypass 16 is supplied is maintained or switched to the anode to perform electrolysis. Chlorite water is generated.
[0038]
That is, the electric control device 19 performs cleaning and sterilization as shown in FIG. 2 when water from the cleaning bypass 16 is introduced from the outlet side of the cathode chamber 5 as shown in FIGS. 2a and 2b. When the electrode 2 in the cathode chamber 5 is converted to an anode during electrolysis and, conversely, water from the cleaning bypass 16 is introduced from the outlet side of the anode chamber 6 (not shown), the electrode in the anode chamber 6 is replaced. An electrical circuit is configured to be held on the anode.
The anode holding or anodic conversion of the electrode 2 may be operated by a switch or the like interlocked with the water flow of the cleaning bypass 16, and may be operated by another switch before or after the water flow of the cleaning bypass 16. It may be.
[0039]
Thus, during normal electrolyzed water generation, water is supplied from the water supply line 8 to the water supply side of the electrolyzer 7 as shown in FIG. 2a, and is electrolyzed into alkaline water and acidic water in the electrolyzer 7, and a pair of drain lines 9
10 are discharged separately.
[0040]
On the other hand, at the time of cleaning, as shown in FIG. 2b, the first flow path switching means 17 of the water supply line 8 is opened to the cleaning bypass 16 side, and the second flow path switching means 18 on the drain line 9 side is set to the cleaning bypass 16 side. When opened, the water in the water supply line 8 is introduced from the drain side of one electrode chamber 5 of the electrolytic cell 7 through the washing bypass 16 as indicated by the arrow, and the common drainage of the electrode chamber 5 → the water supply branch 15 → the water purifier 12. A water circuit for cleaning and sterilization (hereinafter referred to as a “cleaning water circuit”) that passes through the section 13 → the water supply branch pipe 14 → the other electrode chamber 6 → the other drain pipe 10 is opened, and water from the cleaning bypass 16 is supplied. The electrode polarity of the electrode chamber 5 is switched to the anode and an electrolysis voltage is applied.
[0041]
Therefore, the water supplied to the electrode chamber 5 from the cleaning bypass 16 is electrolytically regulated in the electrode chamber 5 switched to the anode chamber. Since the conditioned water is acidic water, precipitates such as calcium adhering to the electrode chamber 5 and the electrolytic diaphragm 4 are dissolved and washed, and the following action is performed by the action of chlorine ions contained in the water. The sterilized water contains a large amount of chlorous acid, and the electrode chamber 5 is sterilized. In particular, the water electrolyzed at the time of cleaning / sterilization is water supplied from the upstream side of the water purifier 12, that is, water from which chlorine is not removed. More hypochlorous acid is generated than when water is passed through.
[0042]
Hypochlorous acid sterilized water discharged from the water supply side of the electrode chamber 5 is washed and sterilized while passing through the water supply branch 14, the common drainage portion 13 of the water purifier 12 and the water supply branch 15, and is switched to the cathode chamber. The electrode chamber 6 is neutralized by electrolysis and discharged from the drain pipe 10.
[0043]
Thus, the electrode chamber of the electrolytic cell 7 which was the cathode chamber at the time of normal electrolytic conditioning is washed with acidic water, and the pipe line in and around the electrolytic cell is formed with hypochlorous acid sterilizing water generated here. Sterilized.
[0044]
In order to increase the concentration of hypochlorous acid in the electrolytic cell 7 at the time of cleaning, the cleaning bypass 16 may be provided with means for suppressing the amount of water supply such as the throttle valve 20 so that the amount of water supplied is reduced and electrolysis is performed slowly. . For the same purpose, the cleaning bypass 16 may be made thinner than the water supply pipe, and moreover, the electrolytic current during cleaning / sterilization electrolysis may be increased as compared with normal alkaline ion water generation electrolysis.
[0045]
Raw water such as tap water contains chlorine ions for generating hypochlorous acid during washing and sterilization electrolysis, but in order to increase the concentration of hypochlorous acid, the washing bypass 16 may contain sodium chloride or the like as necessary. There may be provided means for adding the chloride salt.
[0046]
Further, when the mineral supply cylinder 22 for supplying calcium or the like is provided in the water supply branch pipe 14 communicating with the cathode chamber 5, the water supply is performed so that the mineral is always supplied to the cathode chamber side even if the polarity of the electrode is reversed. A flow path switching device 23 is provided in the branch pipes 14 and 15. Although not shown, a chemical solution addition cylinder for adding a chemical solution necessary for the anode chamber 6 may also be provided in the water supply branch 15 connected to the anode chamber 6.
[0047]
Next, the embodiment of FIGS. 3a and 3b uses electrodes 2 and 3 of the electrolytic cell 7 that can be used for both cathode and anode, for example, electrodes in which a white metal plating such as platinum or iridium is applied to a titanium material. This shows a case where normal electrolysis is performed by changing the polarity of the electrode every predetermined time. In this type of apparatus, the flow path switching device 21 is provided in the drain lines 9 and 10 so that the alkaline ionized water is always discharged from the same water intake port even if the polarity is reversed.
[0048]
In the embodiment of FIGS. 3a and 3b, the water supplied from the cleaning bypass 16 to the electrode chamber 5 of the electrolytic cell 7 through the drain pipe 9 is used as a flow path during cleaning / sterilization electrolysis as shown in FIG. 3b. A washing water circuit is formed which flows into the water supply branch 15 via the switching device 23 and is supplied from the water supply branch 14 to the electrode chamber 6 via the flow path switching device 23 and drained from the drain pipe 10. The electrode 2 is converted to an anode so that washing electrolysis is performed.
[0049]
In all the embodiments of FIGS. 1a to 2a, the cleaning bypass 16 is connected to the drain line 9 of the cathode chamber 5, but it may be connected to the drain line 10 of the anode chamber 6 as shown in FIG. 3a. . In this case, the hypochlorous acid sterilized water generated in the anode chamber 6 is passed through the water supply branch pipes 14 and 15 to the cathode chamber 5 and drained from the drain pipe 9 with the polarity of FIG. Preferably, however, in order to generate hypochlorous acid sterilized water for cleaning and sterilization electrolysis in the cathode chamber 5 during normal electrolysis, water supplied from the cleaning bypass 16 is flowed as shown in FIG. 3b. A switch is made to the electrode chamber 5 via the switching device 21 and a washing water circuit is formed so that water drained from the electrode chamber 6 is drained from the drain pipe 9 via the channel switching device 21. It is desirable to convert the electrode 2 into an anode so that cleaning electrolysis is performed.
When the washing bypass 16 is connected to the drain pipe 10, there is an advantage that the alkaline water drain pipe 9 is cleaned and sterilized with hypochlorous acid sterilizing water at the time of washing electrolysis.
[0050]
In each of the illustrated embodiments, the cleaning bypass 16 is communicated with the outlet side of the electrode chamber 5 or 6 of the electrolytic cell 7 via the drain line 9 or 10, but the outlet of the electrode chamber 5 or 6 is used. You may make it connect directly to the side.
[0051]
4a to 5b show another embodiment of the continuous water electrolyzed water generating device according to the present invention. The embodiment of FIGS. 1a to 3b performs electrolysis from the water supply line 8 on the upstream side of the water purifier 12. While the cleaning bypass 16 is provided to supply water to one outlet of the tank 7, the apparatus 1 of FIGS. 4 a to 5 b uses one of the drain lines 9 or 10 of the electrolytic tank 7, A cleaning flow path switching valve device 26 is provided in association with the water supply pipe line 8 and the drainage pipe line 9 or 10, and the cleaning flow path valve apparatus 26 is switched to supply either one of the electrodes of the electrolytic cell 7 from the water supply pipe line 8. Water is supplied to the exit side of the chamber.
[0052]
That is, in the embodiment shown in FIGS. 4 a and 4 b, the washing flow path switching valve device 26 is provided in association with the alkaline water drain line 9 of the electrolytic cell 7 and the upstream water supply line 8 of the water purifier 12.
In this configuration, during normal electrolysis, as shown in FIG. 4a, water from the water supply line 8 is supplied to the electrolytic cell 7 through the water purifier 12 and the water supply branch pipes 14 and 15, and is electrolyzed into alkaline water and acidic water. The alkaline water is discharged through the alkaline water drain pipe 9 and the acidic water is discharged from the acidic water drain pipe 10 to the drain 11.
On the other hand, at the time of cleaning / sterilization, if the flow path of the cleaning flow path switching valve device 26 is switched to the alkaline water drain pipe 9, the water from the water supply pipe 8 flows back through the alkaline water drain 9 and the electrolytic cell. 7 is supplied from the outlet on the electrode chamber 5 side, flows back from the electrode chamber 5 through the water supply branch 14 to the water purifier 12, and passes through the water supply branch 15 from the common drain 13 of the water purifier 12 to the electrode of the electrolytic cell 7. A washing water circuit that is introduced into the chamber 6 and drains from the acidic water drain pipe 10 to the drain 11 is opened. Thus, when the water from the water supply pipe 8 bypasses the water purifier 12 and passes through the washing water circuit, the circuit is washed and sterilized by the water containing chlorine.
[0053]
5a and 5b, conversely, the washing-time flow path switching valve device 26 is associated with the acidic water drain pipe 10 of the electrolytic cell 7 and the upstream water supply pipe 8 of the water purifier 12. Provided.
In this configuration, at the time of cleaning / sterilization, if the flow path of the cleaning flow path switching valve device 26 is switched from the state of FIG. 5a to the acidic water drain pipe line 10 as shown in FIG. The acid water drain pipe 10 flows backward and water is supplied from the outlet on the electrode chamber 6 side of the electrolytic cell 7, flows back from the electrode chamber 6 through the water supply branch pipe 15 and flows to the water purifier 12, and the common drain section 13 of the water purifier 12. Then, a washing water circuit is opened which is introduced into the electrode chamber 5 of the electrolytic cell 7 through the water supply branch pipe 14 and drained from the alkaline water drain pipe 9 to the drain faucet. Thus, when the water from the water supply pipe 8 passes through the washing water circuit, the circuit is washed and sterilized by the water containing chlorine.
[0054]
6 and 7 show still another embodiment of the electrolyzed water generating apparatus according to the present invention, which includes a water supply line 8 upstream of the water purifier 12 and a drain line 9 of the electrolyzer 7 or 10 is connected to the drainage pipe 9 or 10 (in the case of FIGS. 6 and 7, the alkaline water drainage pipe 9). A distribution mechanism 44 is provided for passing water to the electrolytic tank 7 side of the pipe line 9 or 10 and for passing the remaining water to the water outlet side of the drain pipe line 9 or 10.
As shown in FIG. 6, the distribution mechanism 44 is preferably provided with a throttle portion 45 in the water passage to the drain pipe outlet, thereby ensuring water passage to the electrolytic cell 7 side and a necessary amount. The above water should not be drained from the spout.
[0055]
That is, tap water contains chlorine and has sterilizing power itself, but all of the cleaning water such as tap water supplied to the drain line 9 or 10 is passed to the electrolytic cell 7 side. Of these drainage pipes, the drainage pipe downstream of the washing flow path switching valve device 26 is not washed or sterilized at all, whereas a part of tap water is washed as shown in FIGS. By making it flow to the drain pipe downstream of the hour channel switching valve device 26, the water outlet of the drain pipe is cleaned and sterilized with cleaning water such as tap water.
[0056]
As the cleaning flow path switching valve device 26, a switching valve is used in FIG. 6 and a branch faucet is used in FIG. 7, but the water supply / distribution mechanism 44 for cleaning water can be applied to any of them. is there.
[0057]
In the apparatus of FIGS. 4a to 7, the same reference symbols as those of the apparatus of FIGS. 1a to 3b denote members having the same functions. For example, when hypochlorous acid is generated in the water of the washing water circuit and sterilized, the electrode in the electrode chamber supplied with water from the outlet side of the electrolytic cell 7 is held or switched to the anode during washing and sterilization. An electric control device 19 similar to the above is provided so that sterilization electrolysis is performed.
[0058]
Further, as shown in FIGS. 5 a and 5 b, the flow path switching device 21 may be provided in the pair of drain pipes 9 and 10, and the flow path switching device 23 may be provided in the water supply branch pipes 14 and 15. Since the functions of these flow path switching devices 21 and 23 are the same as those of FIGS. 2a to 3b, the description thereof is omitted.
[0059]
Further, in the case of the device provided with the electric control device 19, in order to increase the hypochlorous acid concentration of the electrolytic cell 7 at the time of washing by limiting the amount of water supplied to the washing water circuit, the washing flow path switching valve device. 26, it is desirable to provide an orifice, a flow restrictor, and a flow restrictor 27 for providing a flow restricting effect in a water passage connecting the water supply conduit 8 to the one drain conduit of the electrolytic cell 7.
[0060]
The switching operation of the first flow path switching means 17 and the second flow path switching means 18 in FIGS. 1a to 3b, the switching operation of the cleaning flow path switching valve device 26 and the cleaning electrolysis operation in FIGS. Electricity may be used. For example, cleaning and sterilization by the above washing electrolysis may be performed manually or by automatic means such as a timer at night when normal electrolytic water conditioning is not performed, or the normal electrolytic water conditioning time is integrated and set Cleaning electrolysis may be automatically performed when the integrated value is reached, or a warning for cleaning electrolysis may be issued.
[0061]
The embodiment of FIGS. 2a to 7 only needs to switch the polarity of the electrode only during cleaning and sterilization, so that a relatively inexpensive electrode material such as stainless steel can be used for the normal electrolysis cathode, but the stainless electrode is switched to the anode. When cleaning and sterilization electrolysis is performed, hypochlorous acid is less generated. Therefore, if you want to increase the generation of hypochlorous acid during cleaning and sterilization electrolysis, the electrode material that serves as the anode during cleaning and sterilization electrolysis is titanium. It is desirable to use a material in which a white metal plating is applied to the material, for example, a titanium material coated with platinum and iridium.
[0062]
Cleaning and sterilization by cleaning and sterilization electrolysis are performed for a predetermined time set in advance, and an alarm lamp or the like is warned during cleaning and sterilization.
[0063]
Furthermore, after sterilization and sterilization by washing electrolysis, water is passed for a predetermined time before using as normal electrolysis, and hypochlorous acid sterilized water is drained. The flow path may be switched to the drain side so that water is not discharged from the alkaline water intake.
[0064]
The above description exemplifies the embodiment of the present invention and is not limited to this.
For example, a microfilter or a hypochlorous acid generator may be interposed in a pipeline through which water is supplied during cleaning and sterilization.
Moreover, the water purifier 12 is not limited to the one having a built-in filter or microfilter, and the water purifier 12 and the filter or microfilter may be separated.
[0065]
FIGS. 8 a to 8 d show a preferred embodiment of the cleaning flow path switching valve device 26 used in the apparatus of FIGS. 6 and 7, and this cleaning flow path switching valve device 26 includes a hollow tubular valve casing 28. A water supply outlet 29 to the water purifier 12 is formed on one side, and a drain outlet 30 communicating with one drain pipe drainage part of the electrolytic cell 7 is formed on the other side. A water supply inlet 31 is provided between the water supply outlet 29 and the drain outlet 30. Further, between the drain outlet 30 of the valve casing 28 and the water supply inlet 31, a washing water outlet 32 connected to one drain pipe of the electrolytic cell 7 is provided.
[0066]
A valve seat 33 is provided between the water supply inlet 31 and the water supply outlet 29 in the hollow internal water passage of the valve casing 28, and another valve seat 34 is provided between the water supply inlet 31 and the wash water outlet 32. Is provided.
[0067]
A valve body 35 is disposed between the valve seats 33 and 34, and the valve body 35 is fixed to an operation rod 36 that is inserted from the outside of the valve casing 28 in a liquid-tight and slidable manner in the axial direction. . Further, the operating rod 36 is reciprocated by connecting a tip end projecting to the outside of the valve casing 28 to a driving device 37 such as a motor. The valve seat 34 is assembled so as to selectively open and close.
[0068]
The valve body 35 drains a part of the water introduced from the water supply inlet 31 to the drainage outlet 30 when the water passage from the water supply inlet 31 to the washing water outlet 32 and the drainage outlet 30 is opened at the tip side thereof, A flow restrictor 38 for draining the remaining water from the washing water outlet 32 is integrally provided.
[0069]
The flow restrictor 38 shown in FIGS. 8a to 8d has a cylindrical body 40 with a front end opening in which a closing member 39 is formed on the outer periphery of the front part to contact the inner wall surface of the valve casing 28 and close the water passage to the drain outlet 30. In addition, a notch plate 41 that forms a water passage to the washing water outlet 32 is formed on the outer periphery of the rear portion of the cylindrical body 40, and the interior of the cylindrical body 40 is penetrated from the rear of the notched plate 41 to the hollow interior. Thus, a water passage hole 42 communicating with the drain outlet 30 is formed.
A flexible check valve 43 is provided behind the drain outlet 30 of the valve casing 28 to allow drainage to the drain outlet 30 side and restrict the backflow of water from the drain outlet 30 side. Yes.
[0070]
Thus, at the time of normal electrolysis for generating alkaline water as shown in FIG. 6a, water introduced from the water supply inlet 31 is supplied from the water supply outlet 29 to the water purifier.
On the other hand, when the valve body 35 moves to the state shown in FIG. 6c during cleaning and sterilization, a part of the water introduced from the water supply inlet 31 is discharged from the drain outlet 30 through the water passage hole 42 of the throttle member 38, and the rest The water is discharged from the washing water outlet 32 through the notch plate 41 of the throttle member 38. Therefore, the flow rate of water supplied from the cleaning water outlet 32 to one electrode chamber of the electrolytic cell 7 during cleaning sterilization is reduced by the throttle member 38.
[0071]
FIGS. 9a and 9b show still another embodiment of the present invention. In this continuous water electrolyzed water generating apparatus 1, the water supply line 8 is connected to the cathode chamber 5 and the anode chamber 6 of the electrolytic cell 7 independently. The water supply branch 14 branched to a pair of water supply branch pipes 14 and 15 communicating with the cathode chamber 5 is provided with an adsorption water purifier 12a such as activated carbon, and a filter water purifier 12b such as a microfilter is provided downstream thereof. It is. Although not shown in the drawing, as a modification of the above, a configuration in which an adsorption water purifier 12a is provided in the water supply line 8 and a filtration water purifier 12b is provided in the cathode chamber side water supply branch 14 may be adopted. In such an electrolyzed water generating apparatus, the pipe between the adsorption water purifier 12a and the filtration water purifier 12b, the water supply branch 15 on the anode chamber 6 side, and the drain pipe 10 in the anode chamber 6 are mutually connected. At the time of cleaning, the two water supply branches 14b and 15b on the electrolytic cell 7 side are separated from the water supply branches 14a and 15a on the water supply pipe line 8 and communicated with each other, and the anode chamber side water supply pipe 15a connected to the water supply pipe 8 is connected. And a flow path switching valve 46 for communicating the anode chamber side drain pipe 10 with each other.
[0072]
With the above configuration, during normal electrolyzed water generation operation, as shown in FIG. 9 a, the raw water supplied from the water supply branch 14 of the water supply pipe 8 is a normal electrolysis flow path of the adsorption water purifier 12 a and the flow path switching valve 46, Water is supplied to the cathode chamber 5 of the electrolytic cell 7 through the filtration water purifier 12 b and the chemical solution addition cylinder 22, and the raw water supplied from the water supply branch 15 passes through the normal electrolysis channel of the channel switching valve 46 to pass through the electrolytic cell 7. The anode chamber 6 is supplied with water.
Thus, alkaline water is generated in the cathode chamber 5 by application of the electrolysis voltage and discharged from the drain pipe 9, and acid water is generated in the anode chamber 6, and the normal flow of the flow path switching valve 46 from the drain pipe 10. It is discharged to the drain 11 through the flow path during electrolysis.
[0073]
9b, when the flow path switching valve 46 is switched to the cleaning circuit side as shown in FIG. 9b, the water supply pipe 14b connected to the cathode chamber 5 of the electrolytic cell 7 and the water supply pipe connected to the anode chamber 6 are used. The passage 15b is disconnected from the water supply branch pipes 14a and 15a on the water supply pipe line 8 side through the switching passage of the flow path switching valve 46 and communicates with each other.
On the other hand, the water supply branch 15 a on the side of the water supply pipe 8 and the drain pipe 10 on the side of the anode chamber 6 communicate with each other via the switching passage of the flow path switching valve 46.
[0074]
Thus, when the flow path switching valve 46 is switched to the washing circuit side, the water supply pipe 8 to the water supply branch 15a → the flow path switching valve 46 → the drain pipe 10 → the anode chamber 6 → the water supply branch 15b → the flow path switching valve 46 → The washing circuit to the water supply branch pipe 14b → filtered water purifier 12b → cathode chamber 5 → drainage line 9 is opened and closed. By supplying water (washing water) from the water supply line 8 to the washing circuit, the electrolytic cell 7 and the filtered purified water are supplied. The entire cleaning circuit including the vessel 12b is cleaned.
[0075]
Further, during this cleaning, when an electrolytic voltage is applied to the electrodes 2 and 3 of the electrolytic cell 7 (adding a chloride salt such as sodium chloride to the cleaning water as necessary), hypochlorous acid water is generated in the anode chamber 6. The anode chamber 6 of the cleaning circuit and the downstream cleaning circuit are cleaned and sterilized with hypochlorous acid water.
[0076]
In particular, when hypochlorous acid water is generated and sterilized, it is advantageous to reduce the flow rate of the washing water and to generate hypochlorous acid water having a sufficient concentration in the anode chamber 6. For this reason, in the embodiment of FIG. 9 b, the throttle valve 24 is provided in the flow path connecting the water supply branch 15 a of the flow path switching valve 46 and the drain pipe 10.
Furthermore, as shown in FIG. 9b, a part of the water supply flow rate at the time of cleaning may be used as cleaning water, and a part may be drained into the drain. In this case, a throttle valve 48 is provided in the drainage channel 47 to the drain.
[0077]
FIG. 9c is a further improvement of the apparatus of FIGS. 9a and 9b. In this embodiment, the water supply line 15b connected to the anode chamber 6 from the flow path switching valve 46 and the drainage of the filter water purifier 12b are shown. When the water pressure in the anode chamber side water supply line 15b rises above a predetermined pressure during the cleaning between the outlets 63, a part of the electrolytic acid water for washing flowing through the water supply line 15b is filtered by the microfilter 12b. A one-way detour cleaning circuit 65 that bypasses the filter 64 and flows to the discharge port 63 is provided.
[0078]
The water supply line 15b becomes a water supply path to the filtration water purifier 12b when the flow path switching valve 46 is switched to the cleaning circuit as shown in FIGS. 9b and 9c. When the circuit is switched, the raw water supply to the cathode chamber 5 is stopped, and the whole or most of the raw water supply water flows backward through the anode chamber 6 of the electrolytic cell 3 to the water supply line 15b, and the water pressure in the water supply line 15b increases. On the other hand, in the filtration water purifier 12, a part of the raw water flows during normal alkaline water generation electrolysis, and the other water is supplied to the anode chamber 6, so that the washing water of the drain pipe 10 whose water pressure has increased during washing. When the entire amount flows into the filter water purifier 12b, the water pressure in the anode chamber 6 increases due to the resistance of the microfilter 64, and the diaphragm 4 may be damaged. In particular, this tendency increases when the microfilter 64 is clogged.
The detour cleaning circuit 65 is a pressure relief circuit for preventing this, and when the cleaning circuit is opened and the water pressure in the electrolytic cell 7 and the water supply line 15b ahead increases, a part of the cleaning water is bypassed. Then, the check valve 67 biased by the spring 66 is opened to flow to the filtered water purifier 12b, and the microfilter 64 of the water purifier 12b is bypassed to flow to the discharge port 63. Therefore, an excessive water pressure is not applied to the diaphragm 4 of the electrolytic cell 7, and the discharge side and the downstream side water circuit of the filter water purifier 12b are washed with the entire amount of acidic water for washing (hypochlorous acid water). The
[0079]
10a and 10b show an example of the flow path switching valve 46. FIG. 10a shows the water circuit during the normal electrolysis of the flow path switching valve 46, and FIG. 10b shows the water circuit during cleaning. . In this embodiment, the function of the throttle valves 24 and 48 is achieved by the positional relationship between the valve body 50 and the respective outlets of the valve casing 49 to the water supply branch pipe 15a and the drain pipe 10.
[0080]
FIGS. 11a and 11b show still another embodiment of the present invention. In this continuous water electrolyzed water generating device, the upstream and downstream positional relationship of the adsorption water purifier 12a and the filtered water purifier 12b in the water supply line 8 is shown. The downstream water supply pipe 8 of the filter water purifier 12b is branched into a water supply branch 14 to the cathode chamber 5 and a water supply branch 15 to the anode chamber, and the electrode chambers 5 and 6 to the electrolytic cell 7 are independently provided to the electrode chambers 5 and 6. A cleaning pipe 51 is connected to the water supply side of the filtration water purifier 12 b from the water supply branch 15 communicating with the anode chamber 6, and the water supply branch pipe is interposed between the anode chamber side water supply branch 15 and the cleaning pipe 51. For example, a flow path switching mechanism 52 such as a three-way valve is provided to selectively open and close 15 and the cleaning pipe line 51.
[0081]
In this apparatus, when the flow path switching mechanism 52 is opened to the water supply branch 15 side, an ordinary electrolyzed water generation water circuit is formed as shown in FIG. 11a. On the other hand, when the flow path switching mechanism 52 is opened to the cleaning pipeline 51 side, As shown in FIG. 11b, the water supply branch 15 connected to the anode chamber 6 and the water supply branch 14 on the cathode chamber 5 side communicate with each other through the cleaning pipe 51 and the filtration water purifier 12a, and from the drain pipe 10 to the anode chamber 6 → the cleaning pipe. A cleaning circuit is formed from 51 → filter water purifier 12b → water supply line 8 → water supply branch pipe 14 → cathode chamber 5 → drain line 9.
Thus, cleaning is performed by passing cleaning water through the cleaning circuit in the above-described direction. At this time, when an electrolysis voltage is applied, hypochlorous acid sterilizing water is generated in the anode chamber 6, and cleaning / cleaning of the cleaning circuit is performed. Sterilized.
[0082]
9a and 9b, a water drain line 53 is branched from a water supply branch pipe 14b communicating with the cathode chamber 5, and a water supply line is provided between the water drain line 53 and the water supply line 8. The drainage pipe 53 is closed by the water pressure at the time of water supply in the pipe 8, the water drain valve 54 is opened to open the drainage pipe 53 by the water pressure at the time of water supply stop, and the on-off valve 55 of the water supply pipe 8 is opened to supply water. When the water drain valve 54 is closed and the water supply is stopped, the water drain valve opens and the remaining water in the apparatus is drained.
This water draining mechanism is used when the water supply is stopped and the reverse polarity washing is performed while draining the water in the electrolytic cell by changing the polarity of the electrode chambers 5 and 6 of the electrolytic cell 7, and the illustration is omitted. However, such a water draining mechanism can be similarly provided in other apparatuses of the present invention.
[0083]
12a and 12b show an example of the drain valve 54. The inside of the valve casing 56 is partitioned by a diaphragm 57 into a chamber 58 on the water supply line 8 side and a chamber 59 on the water drain line 53 side. A valve seat 60 having a valve seat hole 60 ′ is preferably formed in the pipe side chamber 59, and a valve body 61 for opening and closing the valve seat hole 60 ′ is attached to the diaphragm 57, and the diaphragm 57 is attached to the water supply pipe side chamber by a spring 62. The structure is biased to 58.
[0084]
With the above configuration, when water is passed through the water supply pipe 8, the diaphragm 57 and the valve body 61 are pushed toward the chamber 59 due to the increase in water pressure of the chamber 58, and the valve seat 61 opens the valve seat hole 60 of the water drain pipe 53. 'Is closed. Accordingly, during normal electrolysis operation, water is supplied to the electrolytic cell 7 with the drainage pipe 53 closed, and electrolyzed water is generated.
On the other hand, when the water supply to the water supply pipe 8 is stopped, the pressure of the chamber 58 is decreased as shown in FIG. 12B, and the diaphragm 57 is pushed back to the chamber 58 side by the restoring force of the spring 62. Open the valve seat hole 60 '. Thus, the drainage pipe line 53 is opened, and the electrolyzed water generating device is drained.
In the embodiment shown in the figure, the valve seat hole 60 'has a predetermined length L, so that there is a predetermined interval between the stop of water supply from the water supply line 8 and the opening of the water drain line 53. It can be taken. With this configuration, when performing reverse electric cleaning while draining water from the electrolytic cell, the time during which water remains in the electrolytic cell 7 can be lengthened and sufficient reverse electric cleaning time can be taken.
[0085]
Although illustration is omitted, when the electrolyzed water generating apparatus of the embodiment of FIGS. 11a to 12b is a reverse electrolyzed electrolyzed water generating apparatus that generates electrolyzed water by changing the polarity of the electrodes every predetermined time. As in FIG. 1a, an electric control device 19 is provided for switching the electrode chamber on the side for supplying cleaning water from the drain pipe to the anode side during cleaning.
[0086]
【effect】
The present invention introduces water that bypasses the adsorption water purifier, that is, water from which chlorine has not been removed, from one electrode chamber of the electrolytic cell, and supplies one water supply branch to the common drainage part of the water purifier or the inside to the other water supply. Since water is discharged through the branch pipe-the other electrode chamber in this order, the entire downstream water circuit of the water purifier can be washed and sterilized with water containing chlorine.
[0087]
Also, during the electrolytic cleaning, water supplied from the outlet side of one electrode chamber of the electrolytic cell is electrolyzed using the electrode in the electrode chamber as an anode, so that acidic water is generated in the electrode chamber. Deposits such as calcium adhering to the electrode and the electrolytic membrane are washed.
The electrolytically generated water generated in the anode chamber at this time is sterilized water containing a large amount of hypochlorous acid having a strong sterilizing power, and this water is drained through a peripheral water channel such as a water supply pipe and the other electrode chamber. As a result, the electrolytic water tank and its surrounding pipe line (washing water circuit), in particular, the water supply branch pipe that is easy to touch the outside air during mineral replenishment and that is easy to propagate germs by removing chlorine by the water purifier. Sterilized and sterilized with chlorous acid sterilized water. Therefore, the cleaning and sterilizing effect is remarkably improved as compared with the conventional apparatus, and the cleaning, sterilization and sterilization are simultaneously performed by a series of actions.
[0088]
By introducing acidic water generated in the anode chamber at the time of washing and sterilization electrolysis into the cathode chamber, the water in the cathode chamber is neutralized and becomes nearly neutral water. Therefore, as in the conventional case, in the case of mere reverse electric cleaning, even if one of the water in the electrode chamber becomes acidic, the water in the other electrode chamber is alkaline, so the acidic water on the surface of the diaphragm is neutralized and calcium or the like Although the dissolving power has decreased, in the present invention, the alkaline water is neutralized, so this problem can be solved reasonably.
[0089]
Also, when viewed from the other side, hypochlorous acid water generated in the anode chamber is neutralized and drained in the process of passing through the cathode chamber, so there is no harm and does not corrode metal equipment around the drainage.
.
[0090]
Conventional so-called reverse electrolysis requires an expensive electrode such as a titanium / platinum-plated electrode for both cathode and anode, and a flow switching valve for a water supply / drainage pipe is required. Washing electrolysis can be performed with an inexpensive electrode that is made of stainless steel and the anode is made of ferrite or the like, and can be reduced in cost.
[0091]
By providing the distribution mechanism in the flow path switching valve device at the time of cleaning, the drain pipe for supplying the cleaning water is cleaned with tap water containing chlorine up to the water outlet.
[0092]
By providing a bypass washing water circuit that does not allow the microfilter to pass from the anode chamber side water supply pipe to the discharge port of the filtration water purifier, damage to the diaphragm of the electrolytic cell is prevented.
