Description

【０００１】
【発明の属する技術分野】
本発明は水道水の給水導管から残留塩素成分を除去する浄水器を介して供給される被処理水を電気分解して酸性イオン水とアルカリ性イオン水を生成する電解槽を備えた電解水生成装置に関するものである。
【０００２】
【従来の技術】
従来、この種の電解水生成装置として下記の公知文献に記載の先行技術がある。
【０００３】
【特許文献１】
特開平7−16570号公報（第2頁第1欄、図1）
【０００４】
【実用新案文献１】
実開平5−49092号公報（第１頁2記載の要約、図1、２）
【０００５】
【発明が解決しようとする課題】
特許文献1においては、水道水を通水路によって浄水カートリッジを介して電解槽に順次連続的に供給し、電解槽内に設けた電極間に直流電圧を印加して水道水をアルカリ水と酸性水に電気分解しながら取り出すイオン水生成器において、上記浄水カートリッジをバイパスするバイパス通路を設けると共に上記通水路を浄水カートリッジとバイパス通路のどちらか一方に切換える切換手段と、この切換手段をバイパス通路に切換えたとき上記電極への通電を停止する制御手段を設けたイオン生成器が開示されている。
【０００６】
また、実用新案文献１においては、原水供給部と送水路の始端及び環水路の終端との間に切換装置を介装すると共に、送水路と環水路との中途にワンウエイのバイパス路を設けて、切換装置の作動に応じて原水供給部からの原水を送水路と環水路にそれぞれ互い違いに供給するように構成して、送水路や環水路に浄水が滞留していても原水の逆流で押し流され、原水に含まれる塩素成分の殺菌作用によって送水路及び環水路中での微生物の繁殖を防止することができる浄水流路の洗浄切換装置が開示されている。
【０００７】
【発明が解決しようとする課題】
上記のイオン水生成器等においては、活性炭、中空糸膜等を内蔵した浄水器により残留塩素を除去した水道水を電解処理するようにしているため、生成されたイオン水はカルキ臭の少ない無菌の飲料用水として提供し得る利点がある。然しながら、生成直後のアルカリ性イオン水を飲料用水として用いたり冷蔵保存する場合には何ら問題が無いものの、ペットボトル等の容器に貯蔵して常温で保存したり或いは気温の高い時期に屋外に持ち歩く場合には、例えば下記の原因により生成直後の残留塩素を含まない電解水に有害な雑菌が混入して繁殖する虞がある。（なお、酸性イオン水はそれ自体に殺菌力を有しているので菌が繁殖する虞はない。）
▲１▼アルカリ性イオン水をペットボトル等の容器に貯えるとき空気中の浮遊菌が混入する。
▲２▼容器内に付着している菌の洗浄除去が不十分であるとき菌が混入する。
▲３▼手指に付着した菌や言葉を発したとき唾液に含まれた菌が混入する。
【０００８】
上述した有害な雑菌の混入を防止するためには、無菌室内で無菌処理した容器に無菌服、マスク、手袋等を着用して生成直後のアルカリ性イオン水を注入しなければならず、現実には実施不可能である。また、生成直後のアルカリ性イオン水を貯えた容器を沸騰水により加熱殺菌することも考えられるが、加熱による内圧上昇に耐える耐熱容器を用いなければならず、日常の使用には適していない。さらに、不可避的に混入した菌の繁殖を抑制するため、予め塩素成分を含んだ水道水を所定量貯えた容器に生成直後のアルカリ性イオン水を注入して保存した場合には、アルカリ性イオン水の特性が変化するのでアルカリ性イオン水に混入される水道水の量を適正にする必要がありその量を使用者が調整することは困難である。
【０００９】
なお、上記の特許文献１にて提案されたイオン生成器においては、切換手段をバイパス通路に切換えたとき電解槽内の電極間への通電を停止することにより、バイパス通路を通って電解槽に供給される水道水に含まれる残留塩素が浄水カートリッジより下流の通路内での菌の繁殖を防止するようにしたものであるため、生成直後のアルカリ性イオン水の使用を前提としたもので、上述した本発明の解決課題に何らの配慮もされていない。
【００１０】
【本発明の目的】
本発明の目的は、上述した問題に対処するため、生成直後の無菌のアルカリ性イオン水をペットボトル等の容器に貯えて常温にて保存したり或いは気温の高い時期に屋外に持ち歩いてもアルカリ性イオン水の注入時に不可避的に混入した菌が繁殖せず衛生上安全に飲料用水として用いることができるアルカリ性イオン水を生成し得る電解水生成装置を提供することにある。
【００１１】
【課題を解決するための手段】
上記の目的を達成するため、本発明は、水道水の給水道管に残留塩素成分を除去する浄水器を介して接続され同浄水器にて浄化されて供給される被処理水をその内部に対向して設けた一対の電極間に直流電圧を付与されることにより電気分解して酸性イオン水とアルカリ性イオン水を生成する電解槽と、該電解槽にて生成された酸性イオン水とアルカリ性イオン水を注水する注水導管を設けて配置される電解水生成装置において、前記浄水器にて浄化されて供給される被処理水に前記給水導管から供給される残留塩素成分を含んだ水道水を所定の比率にて混合して低濃度の塩素成分を含む被処理水を前記電解槽に供給する混合手段を設けて、前記電解槽にて生成される前記アルカリ性イオン水に次亜塩素酸ナトリウムが所定濃度にて含有されるようにしたことを特徴とする電解水生成装置を提供するものである。
【００１２】
本発明の実施にあたっては、前記混合手段として、前記浄水器の内部に設けた濾過膜に前記給水導管から供給される残留塩素成分を含んだ水道水の一部を通過させる小径の貫通孔を設けるか、または前記浄水器の上流にて前記水道水の給水導管から分岐して同浄水器の下流にて同給水管に連通するバイパス管路に介在させた可変オリフィスを設けるか、或いは前記浄水器の上流にて前記水道水の供給導管から分岐して同浄水器の下流にて同給水道管に連通するバイパス管路に介在させた電磁開閉弁を採用して、該電磁開閉弁を前記アルカリ性イオン水の使用目的に応じて開閉するようにしてもよい。
【００１３】
また、本発明の実施にあたっては、前記注出導管から注出される前記アルカリ性イオン水を生成直後に使用するとき操作される第１注水スイッチと、前記注出導管から注出される前記アルカリ性イオン水を容器に溜めおいて使用するとき操作される第2注水スイッチと、前記浄水器の上流にて前記水道水の給水導管から分岐して同浄水器の下流にて同給水導管に連通するバイパス管路に介在させた電磁開閉弁とを設けて、前記第1注水スイッチが操作されたときには前記電磁開閉弁を閉じた状態にて前記電解槽の電極間直流電圧を付与し、前記第2注水スイッチが操作されたときには前記電磁開閉弁を開放した状態にて前記電解槽の電極間直流電圧を付与し、前記浄水器にて浄化されて供給される被処理水に前記給水導管から供給される残留塩素成分を含んだ水道水が所定の比率にて混合されて前記アルカリ性イオン水に次亜塩素酸ナトリウムが所定濃度にて含有されるようにしてもよい。
【００１４】
【発明の作用・効果】
上記のように構成した電解水生成装置においては、電解槽にて生成されたアルカリ性イオン水は低濃度の次亜塩素酸ナトリウムを含有しているため、ペットボトル等の容器に汲み出して使用するとき不可避的に雑菌が混入しても、有害な菌が繁殖することはなく、生成直後に使用するときは勿論のこと、常温にて保存したり或いは気温の高い時期に屋外に持ち歩いても衛生上安全に使用することができる。また、電解槽にて生成されたアルカリ性イオン水は低濃度の次亜塩素酸ナトリウムを含有しているに過ぎないため、生成直後に飲用してもカルキ臭を殆ど感じない飲料水となる。
【００１５】
【発明の実施の形態】
以下に本発明の最適な実施形態を図面を参照して説明する。図１に示した電解水生成装置は、水道水の給水導管11に給水元栓12と減圧弁13を介して接続した軟水器21と、この軟水器21に内蔵したイオン交換樹脂によりイオン交換されたナトリウムイオンNa+を含む水道水をフィルタ22を介して供給される浄水器23と、この浄水器23にて部分的に残留塩素成分を除去された浄水を被処理水として供給されその内部に設けた一対の電極に直流電圧を付与されて酸性イオン水とアルカリ性イオン水を生成する電解槽24と、この電解槽24にて生成されたアルカリ性イオン水を注水用電磁バルブV1を介して注出タンクTに導出する注出導管25と、電解槽24にて生成された酸性イオン水を酸性イオン水排出用バルブVa及び排水量調節バルブVbを介して排水タンク2７に導出する排水導管26を備えている。なお、浄水器23と電解槽24の間には減圧弁Vd、水経路圧力逃し弁Ve及びアルカリ性イオン水の注出量調節バルブVfが介装されている。
【００１６】
上記のように構成した電解水生成装置において、浄水器23には銀ゼオライト等の抗菌剤を付着させた活性炭を収納しその内部に設けた濾過膜に給水導管から軟水器21を介して供給される残留塩素成分を含んだ水道水の一部を通過させる小径の貫通孔を設けて、所定の比率にて残留塩素成分を含んだ浄水が電解槽24に供給されるようにしてある。
【００１７】
この電解水生成装置の使用にあたって、給水元栓12を開いた状態にて注水用電磁バルブV1が電気的制御盤30に設けた注出スイッチSWのオン操作によって開かれると、給水導管11から供給される水道水が浄水器23内の濾過膜に設けた貫通孔を通して所定の比率により残留塩素成分を含んだ状態で被処理水として電解槽24に供給され、同電解槽24内への被処理水の流れがフローセンサFSにて検出されると制御盤内に設けた制御回路の制御下にて電解槽24内の一対の電極に直流電圧が印加される。これにより、電解槽24内にて酸性イオン水とアルカリ性イオン水が生成され、アルカリ性イオン水は水道水に含まれていた残留塩素が、図2に示したように、ｐＨの変化に伴い次亜塩素酸イオン（ＯＣｌ^-）に変わり、この次亜塩素酸イオンが水道水中や軟水器21にてイオン交換されたナトリウムイオン(Ｎａ⁺)と結合し、低濃度の次亜塩素酸ナトリウムNaOClを含有した状態で注出導管25を通して導出され注出タンクT内に貯えられる。この場合、次亜塩素酸ナトリウムは他の残留塩素と比較して長時間放置しても消失し難い殺菌力を有しているので、ペットボトル等の容器に貯えて保存しても菌の繁殖を抑制する役目を果す。一方、酸性イオン水は排水導管26を通して導出され排水タンク27内に排出される。しかして、注出タンクT内にタイマ制御にて所定量のアルカリ性イオン水が貯えられると、制御盤30内に設けた制御回路の制御下にて注水用電磁バルブV1が閉じて電解槽24内への被処理水の供給が停止したことをフローセンサＦＳが検出し、電解槽24内の電極への給電が停止する。
【００１８】
上記のように構成した電解水生成装置の実施にあたって、通常の水道水に含まれる残留塩素は例えば０．３ｐｐＭであるとすると、被処理水に含まれる残留塩素をそれぞれ０．０５ｐｐＭ〜０．２ｐｐＭ程度に調整すれば、カルキ臭の少ないアルカリ性イオン水が生成される。
【００１９】
かくして、注出タンクT内に貯えられたアルカリ性イオン水は低濃度の次亜塩素酸ナトリウムを含有しているため、ペットボトル等の容器に汲み出して使用するとき不可避的に雑菌が混入しても、有害な菌が繁殖することは無く、生成直後に使用するときは勿論のこと、常温にて保存したり或いは気温の高い時期に屋外に持ち歩いても衛生上安全に使用することができる。
【００２０】
また、電解槽にて生成されたアルカリ性イオン水は低濃度の次亜塩素酸ナトリウムを含有しているに過ぎないため、生成直後に飲用してもカルキ臭を殆ど感じない飲料水となる。また、この電解水生成装置は、不使用状態に長時間おかれても、注出導管25内に滞留したアルカリ性イオン水に含まれた次亜塩素酸ナトリウムによって有害な菌の繁殖を防止することができる。
【００２１】
図３に示した電解水生成装置は、図１に示した電解水生成装置における浄水器23に代えて水道水に含まれる残留塩素成分を除去して残留塩素を含まない状態に浄化した被処理水を電解槽24に供給する浄水器2３Aを採用し、同浄水器2３Aの上流にて水道水の給水導管11から分岐して同浄水器2３Aの下流にて同給水導管11に連通するバイパス管路BPに可変オリフィスVOを介装したもので、その他の構成は図1の電解水生成装置と同じである。
【００２２】
この実施形態においては、給水元栓12を開いた状態にて注水用電磁バルブV1が電気的制御盤に設けた注出スイッチSWのオン操作によって開かれると、給水導管11から供給される水道水が浄水器23Aにより残留塩素を含まない状態に浄化された被処理水として電解槽24に供給され、一方浄水器23Aの上流からバイパス管路BPに流入した水道水は可変オリフィス30にて流量を制御されて所定の比率により低濃度の残留塩素成分を含んだ状態で浄水器23Aの下流にて残留塩素を含まない状態の被処理水に混入して電解槽24内に供給される。これにより、電解槽24内への被処理水の流れがフローセンサFSにて検出されると制御盤30内に設けた制御回路の制御下にて電解槽24内の一対の電極に直流電圧が印加されて、電解槽24内にて酸性イオン水とアルカリ性イオン水が生成され、アルカリ性イオン水は低濃度の次亜塩素酸ナトリウムNaOClを含有した状態で注出導管25を通して導出され注出タンクT内に貯えられる。一方、酸性イオン水は排水導管26を通して導出され排水タンク27内に排出される。しかして、注出タンクT内にタイマ制御にて所定量のアルカリ性イオン水が貯えられると、制御盤30内に設けた制御回路の制御下にて注水用電磁バルブV1が閉じて電解槽24内への被処理水の供給が停止したことをフローセンサＦＳが検出し、電解槽24内の電極への給電が停止する。
【００２３】
かくして、注出タンクT内に貯えられたアルカリ性イオン水は少量の次亜塩素酸ナトリウムを含有しているため、ペットボトル等の容器に汲み出して使用するとき不可避的に雑菌が混入しても、有害な菌が繁殖することは無く、生成直後に使用するときは勿論のこと、常温にて保存したり或いは屋外に持ち歩いても衛生上安全に使用することができる。また、電解槽にて生成されたアルカリ性イオン水は低濃度の次亜塩素酸ナトリウムを含有しているに過ぎないため、生成直後に飲用してもカルキ臭を殆ど感じない飲料水となる。また、この電解水生成装置は、不使用状態に長時間おかれても、注出導管25内に滞留したアルカリ性イオン水に含まれた残留性の高い次亜塩素酸ナトリウムによって有害な菌の繁殖を防止することができる。
【００２４】
図４に示した電解水生成装置は、図３に示した電解水生成装置における可変オリフィスVOに代えて洗浄用電磁バルブV２を設けたもので、その他の構成は図３の電解水生成装置と同じである。この実施形態においては、電解槽２４の制御盤30に第1注出スイッチSW1と第2注出スイッチSW2を設けて、第1注出スイッチSW1をオン操作したときには制御盤30内に設けた制御回路の制御下にて第1注出スイッチＳＷ1が押圧されている間、若しくは第1注出スイッチＳＷ1が再度オン操作されるまで注水用電磁バルブV1のみが開き、第2注出スイッチSW2をオン操作したときには同制御回路の制御下にて注水用電磁バルブV1が所定時間開くと共に洗浄用電磁バルブV2が開くようにしてある。
図４に示した電解水生成装置においては、給水元栓12を開いた状態にて注水用電磁バルブV1が電気的制御盤に設けた第1注出スイッチSW１のオン操作によって開かれると、給水導管11から供給される水道水が浄水器23Aにより残留塩素を含まない状態に浄化された被処理水として電解槽24に供給され、電解槽24内への被処理水の流れがフローセンサFSにて検出されると制御盤内に設けた制御回路の制御下にて電解槽24内の一対の電極に直流電圧が印加されて、電解槽24内にて酸性イオン水とアルカリ性イオン水が生成され、アルカリ性イオン水は残留塩素を含まない状態で注出導管25を通して導出され紙コップ等の容器に注がれて注出直後に飲用されたり、或いはペットボトル等の容器に貯えて冷蔵保存される。一方、酸性イオン水は排水導管26を通して導出され排水タンク27内に排出される。しかして、紙コップ或いはペットボトル等の容器内に所望量のアルカリ性イオン水が注がれると、第1注出スイッチＳＷ1の押圧解除又は同注出スイッチＳＷ1の再度のオン操作の検出により制御盤内に設けた制御回路の制御下にて注水用電磁バルブV1が閉じて電解槽24内への被処理水の供給が停止し、電解槽内の電極への給電が停止する。
【００２５】
かくして、紙コップ或いはペットボトル等の容器に注がれた残留塩素を含まない状態のアルカリ性イオン水は、生成直後に使用するか或いは冷蔵保存する場合に適していて、カルキ臭の少ない状態で飲料水として衛生上安全に供することができる。
【００２６】
また、第2注出スイッチSW2をオン操作したときには、注出タンクＴ内に貯えられる水量に応じた時間、制御盤30に設けた制御回路のタイマ制御下にて注水用電磁バルブV1が開くと共に洗浄用電磁バルブV2が開く。この場合には、給水導管11から供給される水道水が浄水器23Aにより浄化された被処理水として電解槽24に供給され、一方浄水器23Aの上流からバイパス管路BPに流入した水道水は洗浄用電磁バルブV2にて流量を制御されて所定の比率により低濃度の残留塩素成分を含んだ状態で浄水器23Aの下流にて残留塩素を含まない状態の被処理水に混入して電解槽24内に供給される。これにより、電解槽24内への被処理水の流れがフローセンサFSにて検出されると制御盤30内に設けた制御回路の制御下にて電解槽24内の一対の電極に直流電圧が印加されて、電解槽24内にて酸性イオン水とアルカリ性イオン水が生成され、アルカリ性イオン水は低濃度の次亜塩素酸ナトリウムNaOClを含有した状態で注出導管25を通して導出され注出タンクT内に貯えられる。一方、酸性イオン水は排水導管26を通して導出され排水タンク27内に排出される。しかして、注出タンクT内に所定量のアルカリ性イオン水が貯えられると、制御盤内に設けた制御回路の制御下にて注水用電磁バルブV1と洗浄用電磁バルブV2が共に閉じて電解槽24内への被処理水の供給が停止したことをフローセンサFSが検出し、電解槽24内の電極への給電が停止する。
【００２７】
かくして、注出タンクT内に貯えられたアルカリ性イオン水は低濃度の次亜塩素酸ナトリウムを含有しているため、ペットボトル等の容器に汲み出して使用するとき不可避的に雑菌が混入しても、有害な菌が繁殖することは無く、生成直後に使用するときは勿論のこと、常温にて保存したり或いは気温の高い時期に屋外に持ち歩いても衛生上安全に使用することができる。また、この電解水生成装置は、注出スイッチSW2の操作を行った後には、不使用状態に長時間おかれても注出導管25内に滞留したアルカリ性イオン水に含まれた次亜塩素酸ナトリウムによって有害な菌の繁殖を防止することができる。

BACKGROUND OF THE INVENTION
The present invention relates to an electrolyzed water generating apparatus including an electrolyzer that electrolyzes water to be treated supplied from a tap water supply pipe through a water purifier that removes residual chlorine components to generate acidic ion water and alkaline ion water. It is about.
[0002]
[Prior art]
Conventionally, there is a prior art described in the following publicly known literature as this type of electrolyzed water generating apparatus.
[0003]
[Patent Document 1]
Japanese Patent Laid-Open No. 7-16570 (Page 2, column 1, Fig. 1)
[0004]
[Utility model document 1]
Japanese Utility Model Publication No. 5-49092 (Summary on page 1, 2; Fig. 1 and 2)
[0005]
[Problems to be solved by the invention]
In Patent Document 1, tap water is continuously supplied to an electrolytic cell through a water purification cartridge through a water passage, and direct current voltage is applied between electrodes provided in the electrolytic cell so that tap water is mixed with alkaline water and acidic water. In the ion water generator to be taken out while being electrolyzed, a bypass passage for bypassing the water purification cartridge is provided and switching means for switching the water passage to one of the water purification cartridge and the bypass passage, and the switching means is switched to the bypass passage. There is disclosed an ion generator provided with a control means for stopping energization of the electrode when it is.
[0006]
In addition, in the utility model document 1, a switching device is interposed between the raw water supply section and the start end of the water supply channel and the end of the water supply channel, and a one-way bypass is provided in the middle of the water supply channel and the water supply channel. The raw water from the raw water supply section is alternately supplied to the water supply channel and the ring water channel according to the operation of the switching device, so that even if the purified water stays in the water supply channel or the ring water channel, it is pushed away by the reverse flow of the raw water. In addition, there has been disclosed a cleaning switching device for a purified water flow path that can prevent the growth of microorganisms in the water supply channel and the circulating water channel by the sterilizing action of the chlorine component contained in the raw water.
[0007]
[Problems to be solved by the invention]
In the above ionic water generator, etc., since the tap water from which residual chlorine has been removed is electrolyzed by a water purifier incorporating activated carbon, a hollow fiber membrane, etc., the generated ionic water is aseptic as having a reduced odor. There is an advantage that can be provided as drinking water. However, there is no problem when using alkaline ionized water immediately after production as drinking water or refrigerated storage, but when storing it in a container such as a plastic bottle and storing it at room temperature or carrying it outdoors at high temperatures For example, there is a risk that harmful germs may mix in the electrolyzed water that does not contain residual chlorine immediately after generation due to the following causes and propagate. (Note that acid ionic water itself has a sterilizing power, so there is no risk of bacteria breeding.)
(1) When alkaline ionized water is stored in a container such as a plastic bottle, airborne bacteria are mixed in.
(2) Bacteria are mixed when washing and removal of the bacteria adhering to the container are insufficient.
(3) When bacteria or words attached to the fingers are spoken, bacteria contained in saliva are mixed.
[0008]
In order to prevent the contamination of harmful bacteria described above, it is necessary to inject alkaline ionized water immediately after generation by wearing sterile clothes, a mask, gloves, etc. into a container sterilized in a sterile room. It is impossible to implement. Although it is conceivable to heat sterilize the container containing the alkaline ionized water immediately after generation with boiling water, a heat-resistant container that can withstand the increase in internal pressure due to heating must be used, which is not suitable for daily use. In addition, in order to suppress the growth of inevitably mixed bacteria, when alkaline ionized water immediately after generation is stored in a container in which a predetermined amount of tap water containing a chlorine component has been stored, Since the characteristics change, it is necessary to make the amount of tap water mixed in alkaline ionized water appropriate, and it is difficult for the user to adjust the amount.
[0009]
In the ion generator proposed in Patent Document 1 above, when the switching means is switched to the bypass passage, the energization between the electrodes in the electrolytic cell is stopped, so that the electrolytic cell passes through the bypass passage. Residual chlorine contained in the supplied tap water is intended to prevent the growth of bacteria in the passage downstream from the water purification cartridge. No consideration is given to the solution of the present invention.
[0010]
[Object of the present invention]
The object of the present invention is to cope with the above-mentioned problems by storing aseptic alkaline ionized water immediately after generation in a container such as a plastic bottle and storing it at room temperature or even carrying it outdoors during periods of high temperature. It is an object of the present invention to provide an electrolyzed water generating apparatus capable of generating alkaline ionized water that can be used as drinking water safely and hygienically without propagation of bacteria inevitably mixed at the time of water injection.
[0011]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the present invention is connected to the water supply pipe of tap water through a water purifier that removes residual chlorine components, and the treated water supplied after being purified by the water purifier is contained therein. An electrolytic cell that generates acid ionic water and alkaline ionic water by electrolysis by applying a DC voltage between a pair of electrodes provided facing each other, and acidic ionic water and alkaline ions generated in the electrolytic cell In the electrolyzed water generating apparatus arranged by providing a water injection conduit for injecting water, tap water containing residual chlorine components supplied from the water supply conduit to the treated water purified and supplied by the water purifier is predetermined. And mixing means for supplying the water to be treated containing a low concentration chlorine component to the electrolytic cell, so that sodium hypochlorite is predetermined in the alkaline ionized water generated in the electrolytic cell. Contained in concentration Is to provide an electrolytic water generation apparatus, characterized in that the way.
[0012]
In carrying out the present invention, as the mixing means, a small-diameter through-hole through which a part of tap water containing residual chlorine components supplied from the water supply conduit is passed through a filter membrane provided inside the water purifier is provided. Or a variable orifice that is branched from the tap water supply pipe upstream of the water purifier and is interposed downstream of the water purifier and communicates with the water supply pipe, or the water purifier is provided. An electromagnetic on-off valve that is branched from the tap water supply conduit upstream of the water purifier and interposed in a bypass pipe communicating with the water supply pipe downstream of the water purifier is used, and the electromagnetic on-off valve is made alkaline. You may make it open and close according to the intended purpose of ion water.
[0013]
In carrying out the present invention, a first water injection switch operated when the alkaline ionized water dispensed from the dispensing conduit is used immediately after generation, and the alkaline ionized water dispensed from the dispensing conduit are used. A second water injection switch that is operated when stored in a container, and a bypass line that branches from the tap water supply pipe upstream of the water purifier and communicates with the water supply pipe downstream of the water purifier And when the first water injection switch is operated, a DC voltage between the electrodes of the electrolytic cell is applied in a state where the electromagnetic on / off valve is closed, and the second water injection switch Residual chlorine supplied from the water supply conduit to treated water that is supplied with the DC voltage between the electrodes of the electrolytic cell with the electromagnetic on-off valve opened when operated, and purified and supplied by the water purifier Sodium hypochlorite in the alkaline ionized water tap water containing minute are mixed in a predetermined ratio may be contained at a predetermined concentration.
[0014]
[Operation and effect of the invention]
In the electrolyzed water generating apparatus configured as described above, since the alkaline ionized water generated in the electrolyzer contains low-concentration sodium hypochlorite, when pumped into a container such as a plastic bottle Inevitable contamination will not propagate even if bacteria are inevitably mixed. Of course, when used immediately after generation, it can be stored at room temperature or carried outdoors during periods of high temperature. It can be used safely. Moreover, since the alkaline ionized water produced | generated in the electrolytic tank only contains the low concentration sodium hypochlorite, even if it drinks immediately after production | generation, it becomes a drinking water which hardly feels a smell of a lime.
[0015]

A small-diameter through hole through which a part of tap water containing residual chlorine components passes is provided so that purified water containing residual chlorine components is supplied to the electrolytic cell 24 at a predetermined ratio.
[0017]
When using this electrolyzed water generating device, when the water supply electromagnetic valve V1 is opened by turning on the discharge switch SW provided in the electrical control panel 30 with the water supply main tap 12 opened, the water supply conduit 11 supplies the water. Tap water is supplied to the electrolytic cell 24 as treated water in a state containing residual chlorine components at a predetermined ratio through a through-hole provided in the filter membrane in the water purifier 23, and the treated water into the electrolytic cell 24 Is detected by the flow sensor FS, a DC voltage is applied to the pair of electrodes in the electrolytic cell 24 under the control of a control circuit provided in the control panel. As a result, acidic ionic water and alkaline ionic water are generated in the electrolytic cell 24, and the residual chlorinated water contained in the tap water is sublimated with the change in pH as shown in FIG. chlorate ion (OCl ^-) instead, the hypochlorite ions are bonded with tap water and the water softener 21 and ion-exchanged sodium ion (Na ^+), containing a low concentration of sodium hypochlorite NaOCl In this state, it is led out through the pouring conduit 25 and stored in the pouring tank T. In this case, sodium hypochlorite has a sterilizing power that is difficult to disappear even if left for a long time compared to other residual chlorine, so that it can propagate even if stored in a container such as a plastic bottle. It plays a role of suppressing. On the other hand, acidic ionized water is led out through the drainage conduit 26 and discharged into the drainage tank 27.

Then, in a state containing a low concentration residual chlorine component at a predetermined ratio, it is mixed into the water to be treated that does not contain residual chlorine downstream of the water purifier 23A and supplied into the electrolytic cell 24. As a result, when the flow of water to be treated into the electrolytic cell 24 is detected by the flow sensor FS, a DC voltage is applied to the pair of electrodes in the electrolytic cell 24 under the control of a control circuit provided in the control panel 30. When applied, acidic ionic water and alkaline ionic water are generated in the electrolytic cell 24, and the alkaline ionic water is led out through the dispensing conduit 25 in a state containing low-concentration sodium hypochlorite NaOCl. Stored within. On the other hand, acidic ionized water is led out through the drainage conduit 26 and discharged into the drainage tank 27. Thus, when a predetermined amount of alkaline ionized water is stored in the pouring tank T by the timer control, the pouring electromagnetic valve V1 is closed under the control of the control circuit provided in the control panel 30, and the electrolytic cell 24 is filled. The flow sensor FS detects that the supply of the water to be treated to has stopped, and power supply to the electrode in the electrolytic cell 24 is stopped.
