Description

【０００１】
【発明の属する技術分野】
本発明は、銀イオン含有電解生成酸性水や銀イオン含有電解生成アルカリ性水等を電解生成することができる電解水生成装置に関する。
【０００２】
【従来の技術】
銀イオンを含有する電解生成酸性水や電解生成アルカリ性水等銀イオン含有する電解生成水は、銀イオンの殺菌能が付加されている電解生成殺菌水として注目されており、その製造のための電解水生成方法や電解水生成装置は多数提案されている。
【０００３】
従来の電解水生成装置は、例えば、特公平２−８７９８号公報に開示されているように、銀または銀成分を含有する電極を陽極電極とする銀電極電解槽と、イオン透過可能な隔膜にて区画された一対の電解室を有する有隔膜電解槽を備えて、有隔膜電解槽の陽極電解室および陰極電解室の一方または両方が、供給管路を介して銀電極電解槽に直列的に接続して構成されているものである。当該電解水生成装置の使用態様では、銀イオン含有電解生成酸性水、銀イオン非含有電解生成酸性水、銀イオン含有電解生成アルカリ性水、銀イオン非含有電解生成アルカリ性水を選択的に生成することができるものである。
【０００４】
当該電解水生成装置を使用して、銀イオン含有電解生成酸性水および／または銀イオン含有電解生成アルカリ性水を生成するには、被電解水を、先ず銀電極電解槽に供給して電解して銀イオンを含有する電解生成水（銀イオン含有電解生成水）を生成し、当該電解生成水を、有隔膜電解槽のいずれか一方または両方に供給して電解する電解水生成方法が採られる。当該電解水生成装置によれば、当該電解水生成方法を採ることにより、銀イオン含有電解生成酸性水および／または銀イオン含有電解生成アルカリ性水を生成することができる。
【０００５】
このように、当該電解水生成装置は、銀イオン含有電解生成酸性水および／または銀イオン含有電解生成アルカリ性水を生成するための専用の電解水生成装置として使用し得ることは当然であるが、銀イオン非含有電解生成酸性水および銀イオン非含有電解生成アルカリ性水を生成する能力を当然有することから、銀イオン非含有電解生成酸性水および／または銀イオン非含有電解生成アルカリ性水を生成するために使用することは、当該電解水生成装置の使用形態としては極めて有効なことである。
【０００６】
【発明が解決しようとする課題】
ところで、当該電解水生成装置において、銀イオン非含有電解生成酸性水および／または銀イオン非含有電解生成アルカリ性水を生成する場合には、被電解水を、先ず電解運転停止状態にある銀電極電解槽を通して、有隔膜電解槽の陽極電解室および／または陰極電解室に供給して、被電解水を陽極電解室および／または陰極電解室で電解させる使用態様が採られることになる。
【０００７】
当該電解水生成装置において、このような使用態様を採用した場合には、その後の銀電極電解槽の電解運転開始時には、定電流電解運転において、設定された銀イオン濃度の銀イオン含有電解生成水が生成される電解条件となる一定の電解電圧に達するのに時間がかかるという遅延現象（電解電圧遅延現象という）が発生する。電解電圧が一定になるまでに要する時間は、被電解水を、電解運転停止状態の銀電極電解槽を通している継続時間が長いほど長くなる傾向にあり、換言すれば、電解電圧遅延時間が長くなる傾向にある。電解電圧遅延現象の発生は、要求されるスペックの電解生成水を迅速に供給する上で大きな問題となる。
【０００８】
当該電解電圧遅延現象が発生する理由は、必ずしも定かではないが、被電解水として水道水やその他の一般水を使用する場合、被電解水中に含有されている塩素イオン（水質基準２００ｍｇ／Ｌ以下、５〜２５ｍｇ／Ｌ）やその他の成分が電極表面で電極成分である銀と反応したり、電極表面で酸素の吸着がおこり、銀電極電解槽で電解を開始する段階で、電極表面の反応生成物が一定の電解電圧になるまでの律速過程となり、意図する銀イオンの溶出が開始されるまでに電気エネルギーを消費しているものと推測される。
【０００９】
従って、本発明の目的は、銀電極電解槽と有隔膜電解槽を有する電解水生成装置における銀イオン非含有電解生成酸性水および／または銀イオン非含有電解生成アルカリ性水を生成する使用態様に起因して、銀電極電解槽で発生する上記した電解電圧遅延現象を防止して、要求されるスペックの電解生成水を迅速に供給し得るようにすることにある。
【００１０】

【００１５】
また、本発明に係る第２の電解水生成装置においては、当該電解水生成装置を、被電解水を前記有隔膜電解槽へ供給するための供給管路を備えるとともに、同供給管路を迂回して前記有隔膜電解槽で生成される電解生成水を流出させるたの一対の流出管路のそれぞれに分岐して至るバイパス管路を備える構成として、同バイパス管路に前記銀電極電解槽を配設し、銀イオン非含有電解生成酸性水および銀イオン非含有電解生成アルカリ性水の生成時には、前記バイパス管路を遮断した状態で被電解水を前記有隔膜電解槽に供給して電解するようにすることができる。
【００１６】
また、本発明に係る第３の電解水生成装置は、イオン透過可能な隔膜にて区画された一対の電解室を有する有隔膜電解槽と、銀または銀成分を含有する電極を陽極電極とし前記有隔膜電解槽と直列する銀電極電解槽を備え、銀イオン含有電解生成酸性水、銀イオン非含有電解生成酸性水、銀イオン含有電解生成アルカリ性水、銀イオン非含有電解生成アルカリ性水を選択的に生成可能な電解水生成装置であって、当該電解水生成装置は、前記有隔膜電解槽で生成される電解生成水の前記銀電極電解槽への供給および非供給を選択的に行うように構成されていて、銀イオン非含有電解生成酸性水および銀イオン非含有電解生成アルカリ性水の生成時には、前記電解生成水の前記銀電極電解槽への供給を遮断した状態で被電解水を前記有隔膜電解槽に供給して電解することを特徴とするものである。
【００１７】
本発明に係る第３の電解生成装置においては、当該電解水生成装置を、前記有隔膜電解槽で生成される電解生成酸性水を流出する流出管路と電解生成アルカリ性水を流出する流出管路を備えるとともに、これら両流出管路のいずれか一方が同流出管路に至るバイパス管路を備える構成として、同バイパス管路に前記銀電極電解槽を配設し、銀イオン非含有電解生成酸性水および銀イオン非含有電解生成アルカリ性水の生成時には、前記バイパス管路を遮断した状態で被電解水を前記有隔膜電解槽に供給して電解するようにすることができる。
【００１８】
また、本発明に係る第３の電解水生成装置においては、当該電解水生成装置を、前記有隔膜電解槽で生成される電解生成酸性水を流出する流出管路と電解生成アルカリ性水を流出する流出管路を備えるともに、これら両流出管路の両方が同流出管路に至るバイパス管路を備える構成として、同バイパス管路に前記銀電極電解槽を配設して、銀イオン非含有電解生成酸性水および銀イオン非含有電解生成アルカリ性水の生成時には、前記バイパス管路を遮断した状態で被電解水を前記有隔膜電解槽に供給して電解するようにすることができる。
【００１９】
【発明の作用・効果】
本発明に係る各電解水生成装置においては、銀イオン含有電解生成酸性水、銀イオン非含有電解生成酸性水、銀イオン含有電解生成アルカリ水、銀イオン非含有電解生成アルカリ性水を任意に生成することができるが、特に、銀イオン非含有電解生成酸性水および／または銀イオン非含有電解生成アルカリ性水を生成する場合には、被電解水および有隔膜電解槽で生成される電解生成水を、電解運転停止中の銀電極電解槽を通過させるような手段は全く採っていない。
【００２０】
このため、銀イオン非含有電解生成酸性水および／または銀イオン非含有電解生成アルカリ性水を生成する場合には、被電解水や有隔膜電解槽で生成される電解生成水を電解運転停止中の銀電極電解槽を通過させることに起因する電解電圧遅延現象、すなわち、銀電極電解槽の電解開始時における設定の電解電圧に達するまでの時間が大きく遅延する現象を完全に解消することができる。従って、本発明に係る各電解水生成装置によれば、要求されるスペックの電解生成水を迅速に供給することができるという大きな利点がある。
【００２１】
しかして、本発明に係る第１の電解水生成装置によれば、銀電極電解槽における銀イオン含有電解生成水の生成効率を高めることができるとともに、設定された安定したｐＨの、銀イオン含有および非含有の電解生成酸性水や、銀イオン含有および非含有の電解生成アルカリ性水を生成することができる。
【００２２】
また、本発明に係る第２の電解水生成装置によれば、銀イオン含有電解水を有隔膜電解槽に供給することがないため、有隔膜電解槽内での銀イオン含有電解水からの銀の析出がなく、かつ、析出した銀の各電極や隔膜への付着がない。このため、銀の無駄な消費を防止することができるとともに、有隔膜電解槽での電解効率の低下を防止することができる。
【００２３】
また、本発明に係る第３の電解水生成装置によれば、有隔膜電解槽で生成されれる電解生成酸性水や電解生成アルカリ水の有効成分、銀電極電解槽で生成されれる銀イオン電解生成水の有効成分が希釈されることがなく、設定された濃度の有効成分を含有する各電解生成水を生成することができる。また、当該電解水生成装置によれば、銀イオン含有電解生成水を被電解水とする有隔膜電解はあり得ないことから、有隔膜電解槽内での銀イオン含有電解生成水からの銀の析出がなく、かつ、析出した銀の各電極や隔膜への付着がない。このため、銀の無駄な消費を防止することができるとともに、有隔膜電解槽での電解効率の低下を防止することができる。
【００２４】
【発明の実施の形態】
本発明は、銀イオン含有電解生成酸性水、銀イオン非含有電解生成酸性水、銀イオン含有電解生成アルカリ性水、銀イオン非含有電解生成アルカリ性水を選択的に生成することができる電解水生成装置である。本発明に係る電解水生成装置には、銀電極電解槽と有隔膜電解槽の配置状態から、銀電極電解槽に有隔膜電解槽が直列する第１の電解水生成装置と、銀電極電解槽と有隔膜電解槽とが並列する第２の電解水生成装置と、銀電極電解槽が有隔膜電解槽に直列する第３の電解水生成装置の、タイプを異にする３種類の電解水生成装置がある。
【００２５】
図１には、本発明の第１の電解水生成装置に係る２つの実施形態を示し、図２には、本発明の第２の電解水生成装置に係る３つの実施形態を示し、かつ、図３には、本発明の第３の電解水生成装置に係る２つの実施形態を示している。これらの各実施形態に係る電解水生成装置は、図４に示す銀電極電解槽１０と有隔膜電解槽２０の接続状態の組合わせを異にして構成されているものである。
【００２６】
各電解水生成装置を構成する銀電極電解槽１０は、槽本体１１内に、銀または銀成分を含有する陽極電極１２と、ステンレスや白金成分を含有する常用の陰極電極１３を配設してなる電解槽であって、例えば、水道水を被電解水としている。被電解水は、銀電極電解槽１０内で無隔膜電解され、電解室では、銀イオンを含有する電解生成水（銀イオン含有電解生成水）が生成される。生成された銀イオン含有電解生成水は、銀イオンに起因する殺菌能を有する略中性の電解生成水である。
【００２７】
有隔膜電解槽２０は、槽本体２１内をイオン透過可能な隔膜２２で区画してなるもので、一方の区画室には常用の陽極電極２３を配設して陽極電解室に形成され、他方の区画室には常用の陰極電極２４を配設して陰極電解室に形成されているものである。有隔膜電解槽２０は、例えば、水道水を被電解水としている。被電解水は、有隔膜電解槽２０内で有隔膜電解され、陽極電解室では、酸性の電解生成水（電解生成酸性水）が生成され、かつ、陰極電解室では、アルカリ性の電解生成水（電解生成アルカリ性水）が生成される。電解生成酸性水は、残留塩素に起因する弱い殺菌能を有する弱酸性の電解生成水であり、また、電解生成アルカリ性水は、アルカリ成分に起因する洗浄能を有する弱アルカリ性の電解生成水である。
【００２８】
本発明の第１の電解水生成装置に係る実施形態の第１は、図１（ａ）に示すように、有隔膜電解槽２０の上流側に、銀電極電解槽１０を配置しているものである。当該電解水生成装置は、被電解水を有隔膜電解槽２０に供給するための供給管路３１を備えるとともに、供給管路３１はその下流側に至るバイパス管路３２を備え、銀電極電解槽１０はバイパス管路３２に介装されている。バイパス管路３２は、切替バルブ３２ａを介して供給管路３１に接続されている。
【００２９】
バイパス管路３２は、切替バルブ３２ａの切替操作によって、供給管路３１とは断続されるもので、供給管路３１に対して遮断された状態では、被電解水は、銀電極電解槽１０を通ることなく有隔膜電解槽２０に直接供給される。また、バイパス管路３２は、供給管路３１に対して連通された状態では、被電解水は、銀電極電解槽１０を通って有隔膜電解槽２０に供給される。従って、当該電解水生成装置においては、下記のごとき使用態様を採ることができる。
【００３０】
使用態様の第１は、銀イオン含有電解生成酸性水および銀イオン含有電解生成アルカリ性水を生成する態様である。これらの電解生成水を生成するには、バイパス管路３２を供給管路３１に連通させた状態で、被電解水を、バイパス管路３２を通して銀電極電解槽１０に供給する。被電解水は、銀電極電解槽１０では無隔膜電解を受け、銀イオン含有電解生成水が生成される。生成された銀イオン含有電解水は、有隔膜電解槽２０の陽極電解室および陰極電解室に供給されて、各電解室内で有隔膜電解される。これにより、陽極電解室では、銀イオン含有電解生成酸性水が生成され、銀イオン含有電解生成酸性水は流出管路３３ａを通って目的場所へ流出する。また、陰極電解室では、銀イオン含有電解生成アリカリ性水が生成され、銀イオン含有電解生成アルカリ性水は流出管路３３ｂを通って目的場所へ流出する。
【００３１】
使用態様の第２は、銀イオン非含有電解生成酸性水および銀イオン非含有電解生成アルカリ性水を生成する態様である。これらの電解生成水を生成するには、バイパス管路３２を供給管路３１から遮断した状態で、被電解水を、供給管路３１を通して、銀電極電解槽１０を通すことなく、有隔膜電解槽２０の陽極電解室および陰極電解室に直接供給する。被電解水は、有隔膜電解槽２０内で有隔膜電解を受け、陽極電解室では、電解生成酸性水（銀イオン非含有）が生成され、生成された銀イオン非含有電解生成酸性水は、流出管路３３ａを通って目的場所へ流出する。また、陰極電解室では、電解生成アリカリ性水（銀イオン非含有）が生成され、生成された銀イオン非含有電解生成アルカリ性水は、流出管路３３ｂを通って目的場所へ流出する。
【００３２】
このように、当該電解水生成装置においては、銀イオン含有電解生成酸性水および銀イオン含有電解生成アルカリ性水と、銀イオン非含有電解生成酸性水および銀イオン非含有電解生成アルカリ性水とを選択的に生成することができるが、銀イオン非含有電解生成酸性水および銀イオン非含有電解生成アルカリ性水を生成する場合には、被電解水を、電解運転停止中の銀電極電解槽１０を通過させることは全くない。
【００３３】
このため、被電解水を、電解運転停止中の銀電極電解槽１０を通過させることに起因する、銀電極電解槽１０の電解開始時における設定の電解電圧に達す時間の大きな遅延現象は発生することはない。従って、当該電解水生成装置によれば、要求されるスペック通りの電解生成水を迅速に供給することができるとい大きなう利点がある。
【００３４】
また、当該電解水生成装置によれば、銀イオン含有電解生成酸性水および銀イオン含有電解生成アルカリ性水を生成する際の、銀電極電解槽１０での銀イオン含有電解生成水の生成効率を高めることができるとともに、設定された安定したｐＨの各電解生成水を生成することができる。
【００３５】
本発明の第１の電解水生成装置に係る実施形態の第２は、図１（ｂ）に示すように、有隔膜電解槽２０の上流側に銀電極電解槽１０を配置しているものである。当該電解水生成装置は、バイパス管路３２が有隔膜電解槽２０に直接接続されている点を除いて、図１（ａ）に示す第１実施形態の電解水生成装置と同じ構成となっている。従って、当該電解水生成装置においては、第１実施形態に係る電解水生成装置と同様の使用態様を採ることができて、同等の作用効果を奏することができるものである。
【００３６】
本発明の第２の電解水生成装置に係る実施形態の第１は、図２（ａ）に示すように、銀電極電解槽１０と有隔膜電解槽２０とを並列して配置しているものである。当該電解水生成装置は、被電解水を有隔膜電解槽２０に供給するための供給管路３１を備えるとともに、供給管路３１は、有隔膜電解槽の一方の電解生成水の流出管路３３ａ（例えば電解生成酸性水の流出管路）に至るバイパス管路３２を備えている。バイパス管路３２は、供給管路３１と流出管路３３ａに対して切替バルブ３２ｂを介して接続されている。
【００３７】
バイパス管路３２は、切替バルブ３２ｂの切替操作によって、供給管路３１および流出管路３３ａに対して断続されるもので、供給管路３１および流出管路３３ａに対して遮断された状態では、被電解水は、銀電極電解槽１０を通ることなく有隔膜電解槽２０に供給される。また、バイパス管路３２が供給管路３１および流出管路３３ａに対して連通された状態では、被電解水は、銀電極電解槽１０および有隔膜電解槽２０の両方に供給される。従って、当該電解水生成装置においては、下記のごとき使用態様を採ることができる。
【００３８】
使用態様の第１は、銀イオン含有電解生成酸性水および銀イオン非含有電解生成アルカリ性水を生成する態様である。これらの電解生成水を生成するには、バイパス管路３２を供給管路３１および流出管路３３ａに連通した状態で、被電解水を、供給管路３１およびバイパス管路３２の両方を通して、銀電極電解槽１０および有隔膜電解槽２０の両方に供給する。
【００３９】
有隔膜電解槽２０に供給された被電解水は、有隔膜電解槽２０内で有隔膜電解され、陽極電解室では電解生成酸性水が生成され、また、陰極電解室では電解生成アルカリ性水が生成される。各電解生成水は、各流出管路３３ａ，３３ｂを通って流れ、電解生成アルカリ性水は流出管路３３ｂを通って目的の場所へ流出する。また、銀電極電解槽１０に供給された被電解水は、銀電極電解槽１０内で無隔膜電解され、電解室では銀イオン含有電解生成水が生成される。生成された銀イオン含有電解生成水は、バイパス管路３２から流出管路３３ａ内に流入し、流出管路３３ａ内を流動する電解生成酸性水と混合して、銀イオン含有電解生成酸性水を生成する。生成された銀イオン含有電解生成酸性水は、流出管路３３ａを通って目的の場所へ流出する。
【００４０】
使用態様の第２は、銀イオン非含有電解生成酸性水および銀イオン非含有電解生成アルカリ性水を生成する態様である。これらの電解生成水を生成するには、バイパス管路３２を供給管路３１および流出管路３３ａから遮断した状態で、被電解水を、供給管路３１を通して、銀電極電解槽１０を通すことなく、有隔膜電解槽２０の陽極電解室および陰極電解室に直接供給する。被電解水は、有隔膜電解槽２０内で有隔膜電解を受け、陽極電解室では、電解生成酸性水（銀イオン非含有）が生成され、生成された銀イオン非含有電解生成酸性水は、流出管路３３ａを通って目的場所へ流出する。また、陰極電解室では、電解生成アリカリ性水（銀イオン非含有）が生成され、生成された銀イオン非含有電解生成アルカリ性水は、流出管路３３ｂを通って目的場所へ流出する。
【００４１】
このように、当該電解水生成装置においては、銀イオン含有電解生成酸性水および銀イオン非含有電解生成アルカリ性水と、銀イオン非含有電解生成酸性水および銀イオン非含有電解生成アルカリ性水とを選択的に生成することができるが、銀イオン非含有電解生成酸性水および銀イオン非含有電解生成アルカリ性水を生成する場合には、被電解水を、電解運転停止中の銀電極電解槽１０を通過させることは全くない。
【００４２】
このため、被電解水を、電解運転停止中の銀電極電解槽１０を通過させることに起因する、銀電極電解槽１０の電解開始時における設定された電解電圧に達す時間の大きな遅延現象は発生することはない。従って、当該電解水生成装置によれば、要求されるスペック通りの電解生成水を迅速に供給することができるとい大きなう利点がある。
【００４３】
また、当該電解水生成装置によれば、銀イオン含有電解生成水を有隔膜電解槽２０に供給することがないため、有隔膜電解槽２０内での銀イオン含有電解水からの銀の析出がなく、かつ、析出した銀の各電極や隔膜への付着がない。このため、銀の無駄な消費を防止することができるとともに、有隔膜電解槽２０での電解効率の低下を防止することができる。
【００４４】
本発明の第２の電解水生成装置に係る実施形態の第２は、図２（ｂ）に示すように、銀電極電解槽１０と有隔膜電解槽２０とを並列配置しているものである。当該電解水生成装置は、バイパス管路３２が有隔膜電解槽２０で生成される電解生成アルカリ性水が流出する流出管路３３ｂに接続されている点を除いて、図２（ａ）に示す第１実施形態の電解水生成装置と同じ構成となっている。従って、当該電解水生成装置においては、銀イオン含有電解生成酸性水を生成することはできないが、銀イオン含有電解生成アルカリ性水を生成でき、この点を除き、第１実施形態に係る電解水生成装置と同様の使用態様を採ることができて、同等の作用効果を奏することができるものである。
【００４５】

【００４８】
使用態様の第１は、銀イオン含有電解生成アルカリ性水および銀イオン非含有電解生成酸性水を生成する態様である。これらの電解生成水を生成するには、バイパス管路３２を流出管路３３ｂに連通した状態で、被電解水を、供給管路３１を通して有隔膜電解槽２０に供給する。有隔膜電解槽２０に供給された被電解水は、有隔膜電解槽２０内で有隔膜電解され、陽極電解室では電解生成酸性水が生成され、また、陰極電解室では電解生成アルカリ性水が生成される。

【００５２】
このため、被電解水や電解生成水を、電解運転停止中の銀電極電解槽１０を通過させることに起因する、銀電極電解槽１０の電解開始時における設定の電解電圧に達す時間の大きな遅延現象は発生することはない。従って、当該電解水生成装置によれば、要求されるスペック通りの電解生成水を迅速に供給することができるという大きなう利点がある。

TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to an electrolyzed water generation apparatus capable of electrolyzing silver ion-containing electrolyzed acidic water, silver ion-containing electrolyzed alkaline water, and the like.
[0002]
[Prior art]
Electrolytically generated water containing silver ions, such as electrolytically generated acidic water and electrolyzed alkaline water containing silver ions, has been attracting attention as electrolyzed sterilized water to which silver ion sterilizing ability has been added. Many water generation methods and electrolyzed water generation devices have been proposed.
[0003]
A conventional electrolyzed water generating apparatus includes, for example, a silver electrode electrolytic cell having an electrode containing silver or a silver component as an anode electrode and an ion-permeable diaphragm as disclosed in Japanese Patent Publication No. 2-8798. A diaphragm electrolytic cell having a pair of electrolytic chambers partitioned in such a manner that one or both of the anodic electrolytic chamber and the cathodic electrolytic chamber of the diaphragm electrolytic cell are connected in series to the silver electrode electrolytic cell via a supply pipe. They are connected and configured. In the usage mode of the electrolyzed water generating apparatus, the electrolyzed acidic water containing silver ions, the electrolyzed acidic water containing no silver ions, the electrolyzed alkaline water containing silver ions, and the electrolyzed alkaline water containing no silver ions are selectively generated. Can be done.
[0004]
In order to generate silver ion-containing electrolytically generated acidic water and / or silver ion-containing electrolytically generated alkaline water using the electrolyzed water generation apparatus, first, electrolyzed water is supplied to a silver electrode electrolytic cell and electrolyzed. An electrolyzed water generation method is used in which electrolyzed water containing silver ions (silver ion-containing electrolyzed water) is generated, and the electrolyzed water is supplied to one or both of the diaphragm electrolyzers for electrolysis. According to the electrolyzed water generating apparatus, by adopting the electrolyzed water generating method, it is possible to generate silver ion-containing electrolyzed acidic water and / or silver ion-containing electrolyzed alkaline water.
[0005]
As described above, it is obvious that the electrolyzed water generating apparatus can be used as a dedicated electrolyzed water generating apparatus for generating silver ion-containing electrolytically generated acidic water and / or silver ion-containing electrolyzed alkaline water. In order to generate silver ion-free electrolytically generated acidic water and / or silver ion-free electrolytically generated alkaline water, since it naturally has the ability to generate silver ion-free electrolytically generated acidic water and silver ion-free electrolytically generated alkaline water. Is extremely effective as a usage form of the electrolyzed water generating apparatus.
[0006]
[Problems to be solved by the invention]
By the way, in the electrolyzed water generating apparatus, when the electrolyzed acidic water containing no silver ions and / or the electrolyzed alkaline water containing no silver ions are generated, the water to be electrolyzed is first converted to the silver electrode electrolyzed state in which the electrolysis operation is stopped. A usage mode in which the water to be electrolyzed is supplied to the anodic electrolysis chamber and / or the cathodic electrolysis chamber of the diaphragm electrolyzer through the cell to electrolyze the water to be electrolyzed in the anodic electrolysis chamber and / or the cathodic electrolysis chamber is adopted.
[0007]
In the electrolyzed water generating apparatus, when such a use mode is adopted, when the electrolysis operation of the silver electrode electrolytic cell is started thereafter, in the constant current electrolysis operation, the silver ion-containing electrolyzed water having the set silver ion concentration is set. A delay phenomenon (referred to as an electrolysis voltage delay phenomenon) occurs in that it takes time to reach a certain electrolysis voltage, which is an electrolysis condition for generating the electrolysis voltage. The time required for the electrolytic voltage to become constant tends to be longer as the duration of the electrolyzed water passing through the silver electrode electrolytic cell in the electrolysis operation stopped state is longer, in other words, the electrolytic voltage delay time is longer. There is a tendency. The occurrence of the electrolysis voltage delay phenomenon is a major problem in promptly supplying electrolysis water having required specifications.
[0008]
The reason why the electrolysis voltage delay phenomenon occurs is not always clear, but when tap water or other general water is used as the water to be electrolyzed, chlorine ions contained in the water to be electrolyzed (water quality standard 200 mg / L or less) , 5 to 25 mg / L) and other components react with silver, which is an electrode component, on the electrode surface, or oxygen is adsorbed on the electrode surface. It is presumed that the process is a rate-determining process until the product reaches a certain electrolytic voltage, and electric energy is consumed until the intended elution of silver ions is started.
[0009]
Therefore, an object of the present invention is attributable to a use mode for generating silver ion-free electrolytically generated acidic water and / or silver ion-free electrolytically generated alkaline water in an electrolyzed water generator having a silver electrode electrolytic cell and a diaphragm electrolytic cell. Accordingly, it is an object of the present invention to prevent the above-described electrolytic voltage delay phenomenon occurring in a silver electrode electrolytic cell and to promptly supply electrolyzed water having required specifications.

The electrolyzed water generating apparatus according to each of these embodiments is configured so that the combination of the connection states of the silver electrode electrolytic cell 10 and the diaphragm electrolytic cell 20 shown in FIG. 4 is different.
[0026]
The silver electrode electrolyzer 10 constituting each electrolyzed water generating apparatus has an anode electrode 12 containing silver or a silver component and a common cathode electrode 13 containing stainless steel or a platinum component disposed in a tank body 11. The electrolyzer is, for example, tap water as the water to be electrolyzed. The water to be electrolyzed is subjected to non-diaphragm electrolysis in the silver electrode electrolytic cell 10, and electrolyzed water containing silver ions (silver ion-containing electrolyzed water) is generated in the electrolysis chamber. The generated silver ion-containing electrolyzed water is substantially neutral electrolyzed water having a sterilizing ability due to silver ions.
[0027]
The diaphragm electrolyzer 20 is formed by partitioning the inside of a tank main body 21 with an ion-permeable diaphragm 22. One of the compartments is provided with a common anode electrode 23 and is formed in the anode electrolyzer. A common cathode electrode 24 is disposed in the compartment (1), and is formed in the cathode electrolysis chamber. The diaphragm electrolyzer 20 uses, for example, tap water as electrolyzed water. The water to be electrolyzed is subjected to diaphragm electrolysis in the diaphragm electrolyzer 20. In the anodic electrolysis chamber, acidic electrolyzed water (electrolyzed acid water) is generated, and in the cathodic electrolysis chamber, alkaline electrolyzed water ( Electrolytically generated alkaline water) is produced. The electrolytically generated acidic water is a weakly acidic electrolytically generated water having a weak bactericidal ability caused by residual chlorine, and the electrolytically generated alkaline water is a weakly alkaline electrolytically generated water having a cleaning ability caused by an alkali component. .
[0028]
The first embodiment of the first electrolyzed water generating apparatus according to the present invention, as shown in FIG. 1 (a), has a silver electrode electrolyzer 10 arranged upstream of a diaphragm electrolyzer 20. It is. The electrolyzed water generating apparatus includes a supply line 31 for supplying water to be electrolyzed to the diaphragm electrolyzer 20, the supply line 31 includes a bypass line 32 extending to a downstream side thereof, and a silver electrode electrolyzer. 10 is interposed in the bypass line 32. The bypass line 32 is connected to the supply line 31 via the switching valve 32a.
[0029]
The bypass line 32 is intermittently connected to the supply line 31 by the switching operation of the switching valve 32a. When the supply line 31 is shut off, the water to be electrolyzed flows through the silver electrode electrolytic cell 10. It is supplied directly to the diaphragm electrolyzer 20 without passing through. In a state where the bypass conduit 32 is communicated with the supply conduit 31, the water to be electrolyzed is supplied to the diaphragm electrolyzer 20 through the silver electrode electrolyzer 10. Therefore, in the electrolyzed water generator, the following usage modes can be adopted.
[0030]
The first usage mode is an embodiment in which silver ion-containing electrolytically generated acidic water and silver ion-containing electrolytically generated alkaline water are generated. In order to generate the electrolysis water, the electrolyzed water is supplied to the silver electrode electrolytic cell 10 through the bypass line 32 in a state where the bypass line 32 is connected to the supply line 31. The electrolyzed water is subjected to non-diaphragm electrolysis in the silver electrode electrolyzer 10 to generate silver ion-containing electrolyzed water. The generated silver ion-containing electrolyzed water is supplied to the anodic electrolysis chamber and the cathodic electrolysis chamber of the diaphragm electrolyzer 20, and is subjected to diaphragm electrolysis in each electrolysis chamber. As a result, in the anode electrolysis chamber, silver ion-containing electrolytically generated acidic water is generated, and the silver ion-containing electrolytically generated acidic water flows out to the destination through the outflow pipe 33a. In the cathode electrolysis chamber, silver ion-containing electrolytically produced alkaline water is generated, and silver ion-containing electrolytically produced alkaline water flows out to the destination through the outflow pipe 33b.
[0031]
The second usage mode is a mode in which silver ion-free electrolytically generated acidic water and silver ion-free electrolytically generated alkaline water are generated. In order to generate these electrolyzed waters, the water to be electrolyzed is passed through the supply line 31 without passing through the silver electrode electrolysis tank 10 while the bypass line 32 is cut off from the supply line 31. It is supplied directly to the anodic electrolysis chamber and the cathodic electrolysis chamber of the tank 20. The water to be electrolyzed is subjected to diaphragm electrolysis in the diaphragm electrolysis tank 20, and in the anode electrolysis chamber, electrolytically generated acidic water (containing no silver ions) is generated. It flows out to the destination through the outflow line 33a. In the cathode electrolysis chamber, electrolyzed alkaline water (containing no silver ions) is generated, and the generated silver-ion-free electrolyzed alkaline water flows out to the destination through the outflow pipe 33b.

As described above, in the electrolyzed water generation apparatus, the silver ion-containing electrolyzed acidic water and the silver ion-containing electrolyzed alkaline water, and the silver ion-free electrolyzed acidic water and the silver ion-free electrolyzed alkaline water are selectively used. When the silver ion-free electrolytically generated acidic water and the silver ion-free electrolytically generated alkaline water are to be generated, the water to be electrolyzed is passed through the silver electrode electrolytic cell 10 in which the electrolysis operation is stopped. Not at all.
[0033]
For this reason, a large delay phenomenon of the time required to reach the set electrolytic voltage at the start of electrolysis of the silver electrode electrolytic cell 10 due to the passage of the water to be electrolyzed through the silver electrode electrolytic cell 10 in which the electrolysis operation is stopped occurs. Never. Therefore, according to the electrolyzed water generation apparatus, there is a great advantage that electrolyzed water as required can be quickly supplied.
[0034]
Further, according to the electrolyzed water generation device, the efficiency of generating silver ion-containing electrolyzed water in the silver electrode electrolytic cell 10 when generating silver ion-containing electrolyzed acidic water and silver ion-containing electrolyzed alkaline water is increased. In addition to this, it is possible to generate each electrolysis water having a set stable pH.

The electrolyzed water generator has the same configuration as the electrolyzed water generator of the first embodiment shown in FIG. 1A except that the bypass pipe 32 is directly connected to the diaphragm electrolyzer 20. I have. Therefore, in the electrolyzed water generation device, the same usage as the electrolyzed water generation device according to the first embodiment can be adopted, and the same operation and effect can be obtained.
[0036]
In the first embodiment of the second electrolyzed water generating apparatus according to the present invention, as shown in FIG. 2A, a silver electrode electrolytic cell 10 and a diaphragm electrolytic cell 20 are arranged in parallel. It is. The electrolyzed water generating apparatus includes a supply pipe 31 for supplying water to be electrolyzed to the diaphragm electrolyzer 20, and the supply pipe 31 is an outflow pipe 33 a of one electrolysis water of the diaphragm electrolyzer. (For example, an outflow pipe of electrolytically generated acidic water) is provided. The bypass line 32 is connected to the supply line 31 and the outflow line 33a via a switching valve 32b.
[0037]
The bypass line 32 is intermittently connected to the supply line 31 and the outflow line 33a by the switching operation of the switching valve 32b. In a state where the supply line 31 and the outflow line 33a are shut off, The water to be electrolyzed is supplied to the diaphragm electrolyzer 20 without passing through the silver electrolyzer 10. In a state where the bypass pipe 32 is connected to the supply pipe 31 and the outflow pipe 33a, the water to be electrolyzed is supplied to both the silver electrode electrolytic cell 10 and the diaphragm electrolytic cell 20. Therefore, in the electrolyzed water generator, the following usage modes can be adopted.
[0038]
The first mode of use is an embodiment in which silver ion-containing electrolytically generated acidic water and silver ion-free electrolytically generated alkaline water are generated. In order to generate the electrolyzed water, the electrolyzed water is passed through both the supply line 31 and the bypass line 32 while the bypass line 32 is connected to the supply line 31 and the outflow line 33a.
