Description

【０００１】
【発明の属する技術分野】
本発明は、水を電気分解した電解水を用いて、例えば食器等に付着した汚れを効果的に落とす洗浄装置およびその洗浄装置を備えた電気機器に関するものである。
【０００２】
【従来の技術】
電解水を用いて汚れを落とす洗浄装置を利用した電気機器の一例として、例えば特許第３１８３１１８号公報に開示された発明があり、図９にその要部を示す。
【０００３】
特許第３１８３１１８号公報に開示された食器洗浄機は、食器洗浄機４０の本体の内部に洗浄槽が設けられ、その前面開口部は扉によって開閉自在に閉塞される。洗浄槽の内底部には、洗浄用ポンプに回転自在に取り付けられた噴射体が設けられており、洗浄用ポンプは、その吸入管の先端部を洗浄槽の底部下方に形成した貯水部内に臨ませるとともに、駆動用モータに接続されて駆動する。また、洗浄槽の内底部の噴射体の下方には、すすぎ水の加熱等に用いられる電気ヒータが配設され、汚れ検知センサからの検出出力に基づいて制御装置により通断電制御される。
【０００４】
洗浄槽の上部外側には、本体外部の水源に給水管４２を介して接続され、洗浄槽内への給水量を調整する給水弁等を内蔵した給水装置４１が設けられており、給水管４２の下流側には、水道水を電気分解して電解水を生成する創水装置４３が配設されている。
【０００５】
創水装置４３は、その外殻を形成するケーシング３０と、その内部をアルカリ水生成室３２および酸性水生成室３３とに区画する隔膜３１と、各生成室３２，３３にそれぞれ配設された陰極である電極３４および陽極である電極３５と、両電極３４，３５から導出して電源３８に接続された電線３６，３７とを備えており、制御装置からの駆動信号に基づいて電極３４，３５間に電圧を印加し、この電圧の印加によって、創水装置４３に送られた水道水が電気分解されて、アルカリ水生成室３２ではｐＨ値が高くなってアルカリ水が生成され、酸性水生成室３３ではｐＨ値が低くなって酸性水が生成される。
【０００６】
また、ケーシング３０の上流側端は給水管４２が接続され、ケーシング３０の下流側端のアルカリ水生成室３２には給水配管４２ａが接続されており、ケーシング３０の下流側端の酸性水水生成室３３には捨水配管４４が接続されていて、捨水配管４４の先端は、上端を洗浄槽の底部と連通連結した排水管の途中に接続されている。そして、この創水装置４３の動作も制御装置によって制御され、創水装置４３、給水装置４１、給水管４２、給水配管４２ａおよび捨水配管４４によって食器洗浄機の洗浄装置が形成される。
【０００７】
このように構成された食器洗浄機４０は、使用者が図示しない操作スイッチを作動すると、制御装置が、給水装置４１と、創水装置４３と、洗浄用ポンプの駆動用モータと、電気ヒータとに駆動信号を送る。これによって、創水装置４３の電極３４，３５間に電圧が印加されて水道水が電気分解され、アルカリ水生成室３２内および酸性水生成室３３内にそれぞれアルカリ水および酸性水が生成される。そして、アルカリ水のみが給水装置４１を介して洗浄槽内に洗浄水として供給され、アルカリ水が食器等に付着している汚れ物質と積極的に反応して除去する。なお、酸性水生成室３３内で生成された酸性水は、捨水配管４４および排水管を通して外部に排水される。
【０００８】
【発明が解決しようとする課題】
上記のような従来の食器洗浄機４０は、その洗浄装置の創水装置４３によって水道水を電気分解し、生成した電解水（アルカリ水）を用いて食器等の洗浄を行うので、アルカリ水が食器等に付着した汚れ物質と反応し、汚れを積極的に除去する。しかしながら、創水装置４３は、アルカリ水である電解水を生成するために、陰極である電極３４および陽極である電極３５を有するため、電気分解時に陰極である電極３４側に水素ガスの気泡が発生し、陽極である電極３５側に酸素ガスの気泡が発生する。この両電極３３，３４間で発生した気泡は、それぞれの生成室３２，３３内に充満し、特に高い電解水（例えばｐＨの高いアルカリ水またはｐＨの低い酸性水）を生成する場合には多量に発生して充満する。
【０００９】
図１１は創水装置４３のアルカリ水生成室３２側の状態を示したもので、水の電気分解が行われると、アルカリ水生成室３２内に水素ガスの気泡Ｋが発生し（図１１の▲１▼）、ケーシング３０の上部角部３０ａなどに溜まり始めて少しずつ大きくなり（図１１の▲２▼〜▲４▼）、大きな気泡Ｋ１を形成する（図１１の▲５▼）。細かい気泡Ｋは、生成されたアルカリ水とともに給水配管４２ａから排出されるものの、大きくなった気泡Ｋ１は、給水配管４２ａから排出されず、さらに大きくなって滞留する（図１１の▲６▼，▲７▼）。
【００１０】
このように、創水装置４３のアルカリ水生成室３２（酸性水生成室３３）内に大きな気泡Ｋ１が形成されてしまうと、その部分には電解されるべき水道水が送られなくなるため、使われる電極３３（電極３４）の面積が狭くなり、その部分に電流が流れなくなって電気分解が行われなくなってしまう。
【００１１】
つまり、図１０に示すように、一定の電圧をかけても気泡Ｋ、特に大きな気泡Ｋ１によって使用面積が縮小された分だけ流れる電流も減ってしまい、アルカリ水生成室３２内の水が入れ替わる時間Ｔの間電圧をかけても所定の電気量が得られず、電流の大きさに比例する電解水のｐＨも低下して所望のｐＨの電解水が得られない（例えば所望のｐＨが１２の電解水が、ｐＨ１０の電解水となってしまう）という問題があった。このように、電解水の生成効率が低下してしまうと、電解水による洗浄効率も低下してしまうおそれがあった。
【００１２】
また、アルカリ水生成室３２（酸性水生成室３３）内で形成された大きな気泡Ｋ１が給水配管４２ａから排出した場合でも、その気泡Ｋ１が洗浄槽に排出されるため、その気泡Ｋ１によって洗浄槽内に供給されるアルカリ水を所定量送り込むことができないという問題があった。そして、所定量のアルカリ水が確保できない場合は、洗浄効率も低下してしまうおそれがあった。
【００１３】
本発明は、上記のような課題を解決するためになされたもので、電気分解時に発生する気泡の滞留を防ぎ、所望のｐＨで所定量の電解水を確実に確保して洗浄効率の低下を防ぐことのできる洗浄装置およびその洗浄装置を備えた電気機器を提供することを目的としたものである。
【００１４】
【課題を解決するための手段】
本発明に係る洗浄装置は、電気分解装置によって生成された電解水を用いて被洗浄物を洗浄する洗浄装置において、水が前記電気分解装置の電解槽に入って出るまでの間の水の移動速度と、電気分解時に前記電解槽で発生した気泡が前記電解槽を出るまでの間の気泡の移動速度とによって生じる時間差に相当する時間、またはこの時間よりも若干短い時間の間、前記電気分解装置の電極に電圧を印加して前記電気分解装置の前記電解槽内の水を電気分解させるとともに、電気分解時に前記電気分解装置の前記電解槽で発生した気泡が前記電解槽を出るまでの間に相当する時間、またはこの時間よりも若干短い時間の間、前記電極への電圧の印加を停止させ、前記電極への電圧の印加および停止を繰り返し行うようにしたものである。
【００１５】
本発明に係る洗浄装置は、水を電気分解して電解水を生成する電気分解装置と、電気分解装置に水を供給する給水路と、電解水を急加熱して蒸気化し電解水の水滴とともに被洗浄物に噴射する蒸気発生噴射装置とを備え、水が前記電気分解装置の電解槽に入って出るまでの間の水の移動速度と、電気分解時に前記電解槽で発生した気泡が前記電解槽を出るまでの間の気泡の移動速度とによって生じる時間差に相当する時間、またはこの時間よりも若干短い時間の間、前記電気分解装置の電極に電圧を印加して電気分解装置の電解槽内の水を電気分解させるとともに、電気分解時に前記電気分解装置の前記電解槽で発生した気泡が前記電解槽を出るまでの間に相当する時間、またはこの時間よりも若干短い時間の間、前記電極への電圧の印加を停止させ、前記電極への電圧の印加および停止を繰り返し行うようにしたものである。
【００１７】
本発明に係る洗浄装置の第１の所定時間は、電気分解装置の電解槽で生成された電解水が所望のｐＨとなるための電気量が得られるまでの間に相当する時間としたものである。
【００１９】
本発明に係る洗浄装置は、電気分解装置によって生成された電解水を用いて被洗浄物を洗浄する洗浄装置において、電気分解装置の電解槽の内壁上部を円弧状または電解槽の周壁に向かって低くなるような傾斜状に形成したものである。
【００２０】
本発明に係る電気機器は、前記洗浄装置を備えたものである。
【００２１】
【発明の実施の形態】
実施の形態１．
図１は本発明の実施の形態１の概略的に示した構成図、図２は本発明の実施の形態１に係るボイラの断面図、図３は本発明の実施の形態１に係る電気分解装置の断面図である。
【００２２】
図において、１は例えば食器洗浄機あるいは洗濯機などの電気機器に設置される洗浄装置で、細型シリンダ形状の蒸気発生噴射装置であるボイラ２と、ボイラ２に電気を供給する電源３と、一端がボイラ２の下流側に接続され他端に噴出口４ａを有する噴出路４と、水を電気分解してアルカリ水および酸性水などの電解水を生成する電気分解装置５と、一端が電気分解装置５の下流側に接続され他端がボイラ２の上流側に接続されて、電気分解装置５で生成された電解水（例えばアルカリ水）を排出する第１の電解水排出路６と、一端が電気分解装置５の下流側に接続され、電気分解装置５で生成された電解水（例えば酸性水）を排出する第２の電解水排出路７と、一端が電気分解装置５の上流側に接続され他端が例えば水道の蛇口あるいは水槽などに接続されて、電気分解装置５に水を供給する給水路８と、給水路８の途中に設けられ電気分解装置５に水を供給するポンプ９とを備えている。なお、給水路８が水道の蛇口に接続された場合は、ポンプ９を省略してもよい。
【００２３】
ボイラ２は、図２に示すように、内部に細型シリンダ状の空間である蒸発室１２を有するフレーム１１と、フレーム１１の内部に埋め込まれフレーム１１を加熱するヒータ１３とを備えており、ボイラ２の一方の側である上流側には、蒸気室１２に連通しその蒸気室１２の径Ｒより小径の第１の電解水排出路６が接続され、ボイラ２の他方の側である下流側には、蒸気室１２に連通しその蒸気室１２の径Ｒより小径の噴出路４が接続されている。そして、第１の電解水排出路６からボイラ２に送られた電気分解装置５からの電解水（アルカリ水）をヒータ１３により急加熱して蒸気化し、急激な体積膨張を利用して水滴が混合した状態で噴出口４ａから噴射する。
【００２４】
電気分解装置５は、図３に示すように、上流側である底部に給水路８が接続された電解槽１４と、電解槽１４の中央に設けられ電解槽１４内を二分して２つの電解水生成室１６，１７を形成する親水性の隔膜１５と、各電解水生成室１６，１７の隔膜１５に対向する内壁にそれぞれ設けられた陰極である電極１８および陽極である電極１９と、各電極１８，１９からそれぞれ導出して電源１０（図１参照）に接続された電線２０，２１とを備えており、電解槽１４の天部で電解水生成室１６の下流側には第１の電解水排出路６が接続され、電解槽１４の天部で電解水生成室１７の下流側には第２の電解水排出路７が接続されている。そして、両電極１８，１９間に直流電圧（例えばＤＣ１０Ｖ）を印加すると、２つの電極１８，１９間に電流が流れて電解槽１４内の水を電気分解し、陰極の電極１８が設けられた電解水生成室１６にはアルカリの電解水であるアルカリ水が生成され、陽極の電極１９が設けられた電解水生成室１７には酸性の電解水である酸性水が生成されて、第１の電解水排出路６からアルカリ水が排出され、第２の電解水排出路７から酸性水が排出される。
【００２５】
このように構成された実施の形態１に係る洗浄装置１を例えば食器洗浄機に設けて、この食器洗浄機を駆動すると、洗浄装置１のポンプ９も駆動して水が給水路８を通って電気分解装置５に送られ、電気分解装置５に入った水は図３の矢印に示すように各電解水生成室１６，１７に分かれて、各電解水生成室１６，１７を通過しながら電気分解され、各電解水生成室１６，１７で生成されたアルカリ水および酸性水が各電解水排出路６，７から排出される。このとき、生成される電解水（アルカリ水および酸性水）のｐＨは各電極１８，１９に流す電流の大きさに比例するため、ｐＨの高いアルカリ水（ｐＨの低い酸性水）を生成する場合は電流を多く流すなど、所望のｐＨに合わせて電流を流す。
【００２６】
ついで、第１の電解水排出路６に排出されたアルカリ水はボイラ２に送られて、ボイラ２のヒータ１３によって急加熱されて蒸気化され、水滴が混合した状態で図示しない汚れが付着した食器等に噴出口４ａから高速噴射される。所定量のアルカリ水が噴射されると、食器洗浄機は洗浄・すすぎ用の水を図示しない給水ホースから洗浄槽内に給水し、汚れ物質と反応して除去したアルカリ水などを食器等から洗い流す洗浄・すすぎを行う。
【００２７】
水の電気分解中、洗浄装置１の電気分解装置５の各電極１８，１９からはガスが発生して電解水生成室１６，１７内に気泡が広がり、押し出されることなく電解槽１４の上部角部１４ａなど溜まり始める。そして、気泡は両電極１８，１９間に電流が流れている間中発生するため、電気分解が継続されているかぎり滞留した気泡はなくならない。そこで、一旦電極１８，１９間に電圧を印加するのを停止して気泡の発生を止め、各電解水生成室１６，１７を通過する水によって気泡を電解槽１４から押し出し、気泡の滞留を防ぐようにする。つまり、この実施の形態１においては、各電極１８，１９に印加する（流す）電圧（電流）を制御することにより、発生した気泡による滞留を防いで電解水の生成効率の低下を防ぐように構成した。
【００２８】
この各電極１８，１９間に印加する（流す）電圧（電流）の制御について、図４を用いて詳しく説明する。
図４は電気分解装置５の一方の電解水生成室１６の斜視図であり、電解水生成室１６の底部から入った水は、下から上に向かって流れる際に電気分解される。電気分解中、電解水生成室１６内に気泡Ｋが発生するが、発生した気泡Ｋは浮力によってその気泡Ｋと同時に同じ位置から電解水生成室１６内を上昇し始めたある水Ｗよりも速く水の中を上昇する。よって、静止水中の気泡Ｋの移動速度をｖｇ［ｍｍ／ｓｅｃ］とし、ある水Ｗが電解水生成室１６を通過する移動速度をν［ｍｍ／ｓｅｃ］（ν＝Ｖ／Ａ、Ｖは電解水生成室１６を通過する水の流量、Ａは電解水生成室１６の横断面積）とすると、電解水生成室１６内を移動する水の中の気泡Ｋの移動速度は、水の移動速度νが加えられることになり、ｖｇ＋ν［ｍｍ／ｓｅｃ］となる。これにより、電解水生成室１６を同時に同じ位置から上昇し始めた水Ｗと気泡Ｋとには、電解水生成室１６を出るのに時間差が生じる。
【００２９】
一方、水の電気分解は、
Ｈ₂Ｏ＋ｅ → １／２Ｈ₂ ＋ＯＨ^-
１／２Ｈ₂Ｏ → １／４Ｏ₂ ＋Ｈ⁺ ＋ｅ
であり、生成する電解水のＨ⁺基あるいはＯＨ^-基のモル濃度をＭ［ｍｏｌ／Ｌ］、電解水生成室１６内の水が入れ替わる時間をＴ［ｓｅｃ］（Ｔ＝Ｈ／ν、Ｈは電解水生成室１６の高さ）、電気分解に必要な電気量をＱ［ｃ］、電圧（電流）を印加して（流して）いる時間をｔ［ｓｅｃ］、流れる電流をＩ［Ａ］とすると、例えば１つのＨ⁺基を作るのに１個の電子（ｅ）が必要で、電子１ｍｏｌの電気量は９６５００［ｃ］であるので、Ｍモル濃度の電解水を作るには、電気量Ｑは
Ｑ＝Ｍ・９６５００
となる。
【００３０】
また、電解水生成室１６内の水を電気分解するのに必要な電流Ｉと電圧を印加している時間ｔは、電流Ｉが一定に流れるとはかぎらないため、電気量Ｑは次式で求められる電流Ｉを０から時間ｔまで積分した値となる。
【００３１】
【数１】

【００３２】
そして、電流Ｉが一定ならば、電気量Ｑは
Ｑ＝Ｉ・ｔ
となり、電流Ｉと時間ｔは、
Ｉ＝Ｍ・９６５００／ｔ
の式（イ）より求められる。
【００３３】
ここで、電圧を印加している時間ｔと、電解水生成室１６内の水が入れ替わる時間Ｔとが等しい（ｔ＝Ｔ）場合、水が電解水生成室１６に入ってから出るまでの間中電気分解は行われ、常に気泡（ガス）が発生することになる。一方、電圧を印加している時間ｔが電解水生成室１６内の水が入れ替わる時間Ｔより短い（ｔ＜Ｔ）場合は、ある水Ｗは時間ｔだけ電圧を印加すれば所望のモル濃度に電気分解されるため、時間Ｔ−ｔの間は電圧を印加する必要がなくなり、その間は気泡（ガス）も発生しない。
【００３４】
上述したように、電解水生成室１６を同時に同じ位置から上昇し始めた水Ｗと気泡Ｋとは電解水生成室１６を出るのに時間差が生じるため、この時間差Δｔを利用して電極に電圧を印加すれば発生した気泡Ｋ（ガス）は時間Ｔ−Δｔの間で電解水生成室１６から出ていくことになる。
つまり、気泡Ｋが電解水生成室１６で発生して出ていくまでの時間Ｔｋは、Ｔ・ν／（ｖｇ＋ν）［ｓｅｃ］であり、時間差ΔｔはＴ−Ｔｋであるから、時間差Δｔを電圧を印加している時間ｔとすると、
ｔ＝Ｔ−Ｔｋ＝Ｔ−Ｔ・ν／（ｖｇ＋ν）＝Ｔ・ｖｇ／（ｖｇ＋ν）
となる。
そして、この時間ｔ＝Ｔ・ｖｇ／（ｖｇ＋ν）の間だけ電圧を印加して時間Ｔ−ｔ（Ｔｋ）の間は電圧の印加を停止する電圧のＯＮ／ＯＦＦ制御を繰り返すことにより、電解水生成室１６内に発生した気泡Ｋは電圧の印加が停止している間に排出され、電解水生成室１６に気泡Ｋがない状態で次の電気分解を行うことができる。
【００３５】
つまり、図５および図６に示すように、電解水生成室１６内に発生した気泡Ｋは、電圧が印加されている時間ｔの間継続して発生し（図６の▲１▼，▲２▼）、電圧の印加が停止されると発生しなくなって（図６の▲３▼）、電圧の印加が停止されている時間Ｔ−ｔの間に電解水生成室１６内を上昇している水（アルカリ水）によって押し出され（図６の▲３▼〜▲５▼）、再び電圧が印加されている時間ｔの間は発生する（図６の▲６▼，▲７▼）。このように、電解水生成室１６内に発生した気泡Ｋは電圧の印加が停止している間に確実に出ていき、電解水生成室１６内に滞留することなく次の電気分解を行うことができる。
【００３６】
なお、時間ｔ＝Ｔ・ｖｇ／（ｖｇ＋ν）を上記の式（イ）に入れると、
Ｉ＝Ｍ・９６５００／｛Ｔ・ｖｇ／（ｖｇ＋ν）｝
となり、電圧を印加する時間ｔの間に所望のモル濃度（ｐＨ）の電解水を得るには上記式より電流の大きさが決まって、その大きさの電流を時間ｔの間流し続けると、所定の電気量が得られて所望のモル濃度（ｐＨ）の電解水が得られる。
【００３７】
このように、気泡Ｋと水Ｗとは電解水生成室１６，１７を通過する速度に差があるため、速度差によって生じる時間差Δｔの間、電極１８，１９間に電圧を印加するようにして、電圧のＯＮ／ＯＦＦ制御を行うようにしたので、電気分解時に発生した気泡Ｋは、電圧の印加を停止しているときに電解水生成室１６，１７に滞留することなく排出され、気泡Ｋによる電極１８，１９の使用面積の縮小を防ぎ、所定の電気量が得られて、電解水の生成効率の低下を防ぐことができる。これにより、所望のｐＨで所定量の電解水を得ることができ、電解水による洗浄効率の低下を確実に防ぐことができる。
【００３８】
なお、上述の実施の形態１では、時間差Δｔの間電圧を印加し、時間Ｔ−Δｔの間は電圧の印加を停止する場合を示したが、電圧の印加を停止する時間を若干短くして気泡Ｋが電解水生成室１６，１７からほぼ出きったころに電圧を印加するようにしてもよく、所定の電気量が得られる範囲で電圧を印加する時間を若干短くするようにしてもよい。これらの場合、電解水生成室１６，１７の上部に若干気泡Ｋが残るが、次の電気分解で発生した気泡Ｋは上部には達しないため、上昇してきた電解水によって気泡Ｋが滞留することなく確実に排出される。よって、これらの場合も同様の効果を奏する。
【００３９】
また、上述の実施の形態１では、食器洗浄機に洗浄装置１を設けた場合を例示して説明したが、洗濯機など他の電気機器に設けてもよい。この場合も同様の効果を奏する。
【００４０】
実施の形態２．
図７は本発明の実施の形態２に係る電気分解装置の電解槽の断面図である。この実施の形態２は、実施の形態１に係る電気分解装置５の電解槽１４において、その内壁の上部角部１４ａを円弧状に形成したものである。
【００４１】
このように構成したことにより、電気分解時に電解槽１４（電解水生成室１６，１７）内に発生した気泡は、電解槽１４から抜けやすくなって上部角部１４ａに滞留しにくくなり、気泡による電解水の生成効率の低下を防ぐことができて、電解水による洗浄効率の低下を確実に防ぐことができる。また、電気分解装置５への電圧のＯＮ／ＯＦＦ制御を行えば、気泡の滞留を確実に防ぐことができ、気泡による電解水の生成効率の低下を防いで、電解水による洗浄効率の低下を防ぐことができる。
【００４２】
なお、上述の実施の形態２では、電気分解装置５の電解槽１４の内壁の上部角部１４ａを円弧状に形成した場合を示したが、図８に示すように、電解槽１４の上部角部１４ａを内周壁から第１の電解水排出路６（第２の電解水排出路７）に向かって傾斜するように形成してもよい。この場合も同様の効果を奏する。
【００４３】

A spray body rotatably attached to a cleaning pump is provided at the inner bottom of the cleaning tank, and the cleaning pump faces a water storage section formed at the tip of the suction pipe below the bottom of the cleaning tank. At the same time, it is connected to a drive motor for driving. In addition, an electric heater used for heating the rinse water is disposed below the jetting body at the inner bottom of the cleaning tank, and the electric power is controlled by the control device based on the detection output from the dirt detection sensor.
[0004]
A water supply device 41 that is connected to a water source outside the main body via a water supply pipe 42 and has a built-in water supply valve that adjusts the amount of water supplied to the cleaning tank is provided outside the upper portion of the cleaning tank. A water generating device 43 that electrolyzes tap water to generate electrolyzed water is disposed on the downstream side.
[0005]
The water generating device 43 is disposed in each of the

generation chambers

32 and 33, the casing 30 that forms the outer shell thereof, the diaphragm 31 that divides the inside of the casing 30 into the alkaline water generation chamber 32 and the acidic water generation chamber 33. An electrode 34 serving as a cathode, an electrode 35 serving as an anode, and

electric wires

36 and 37 derived from both

electrodes

34 and 35 and connected to a power source 38 are provided. A voltage is applied between the two electrodes 35, and by applying this voltage, the tap water sent to the water generating device 43 is electrolyzed, and in the alkaline water production chamber 32, the pH value is increased to produce alkaline water. In the generation chamber 33, the pH value is lowered and acidic water is generated.
[0006]
A water supply pipe 42 is connected to the upstream end of the casing 30, and a water supply pipe 42 a is connected to the alkaline water generation chamber 32 at the downstream end of the casing 30, so that acidic water is generated at the downstream end of the casing 30. A drain pipe 44 is connected to the chamber 33, and the tip of the drain pipe 44 is connected to the middle of a drain pipe whose upper end is connected to the bottom of the washing tank. The operation of the water generating device 43 is also controlled by the control device, and the cleaning device of the dishwasher is formed by the water generating device 43, the water supply device 41, the water supply pipe 42, the water supply pipe 42 a and the drainage pipe 44.
[0007]
In the dishwasher 40 configured as described above, when the user operates an operation switch (not shown), the control device includes a water supply device 41, a water generating device 43, a motor for driving the cleaning pump, an electric heater, Send drive signal to. Thereby, a voltage is applied between the

electrodes

34 and 35 of the water generating device 43 to electrolyze tap water, and alkaline water and acidic water are generated in the alkaline water generation chamber 32 and the acidic water generation chamber 33, respectively. . Then, only alkaline water is supplied as washing water into the washing tank through the water supply device 41, and the alkaline water actively reacts with and removes dirt substances adhering to tableware and the like. In addition, the acidic water produced | generated in the acidic water production | generation chamber 33 is drained outside through the waste water piping 44 and a drain pipe.
[0008]
[Problems to be solved by the invention]
In the conventional dishwasher 40 as described above, tap water is electrolyzed by the water generating device 43 of the washing device, and the generated electrolytic water (alkaline water) is used to wash the tableware and the like. It reacts with dirt substances attached to tableware, etc. and actively removes dirt. However, since the water generating device 43 includes the electrode 34 serving as a cathode and the electrode 35 serving as an anode in order to generate electrolyzed water that is alkaline water, bubbles of hydrogen gas are generated on the side of the electrode 34 serving as a cathode during electrolysis. Oxygen gas bubbles are generated on the side of the electrode 35 that is the anode. The bubbles generated between the

electrodes

33 and 34 are filled in the

respective generation chambers

32 and 33, and a large amount is generated particularly when high electrolytic water (for example, alkaline water having a high pH or acidic water having a low pH) is generated. Occurs and fills.
[0009]
FIG. 11 shows a state of the water generator 43 on the alkaline water generation chamber 32 side. When water electrolysis is performed, hydrogen gas bubbles K are generated in the alkaline water generation chamber 32 (see FIG. 11). {Circle around (1)} and begins to accumulate in the upper corner portion 30a of the casing 30 and gradually increases ((2) to (4) in FIG. 11) to form a large bubble K1 ((5) in FIG. 11). Although the fine bubbles K are discharged from the water supply pipe 42a together with the generated alkaline water, the enlarged bubbles K1 are not discharged from the water supply pipe 42a and become larger and stay ((6) and ▲ in FIG. 11). 7 ▼).
[0010]
Thus, if a large bubble K1 is formed in the alkaline water generation chamber 32 (acidic water generation chamber 33) of the water generating device 43, tap water to be electrolyzed cannot be sent to that portion. As a result, the area of the electrode 33 (electrode 34) is narrowed, and no current flows through that portion, so that electrolysis is not performed.
[0011]
That is, as shown in FIG. 10, even when a constant voltage is applied, the current flowing by the amount of use of the bubble K, particularly the large bubble K1, is reduced, and the time in which the water in the alkaline water generation chamber 32 is replaced is changed. Even if a voltage is applied during T, a predetermined amount of electricity cannot be obtained, and the pH of the electrolyzed water proportional to the magnitude of the current is also lowered, so that electrolyzed water having a desired pH cannot be obtained (for example, the desired pH is 12). There was a problem that the electrolyzed water becomes electrolyzed water having a pH of 10. Thus, if the production efficiency of electrolyzed water is lowered, there is a possibility that the washing efficiency with electrolyzed water is also lowered.
[0012]
Further, even when a large bubble K1 formed in the alkaline water generation chamber 32 (acidic water generation chamber 33) is discharged from the water supply pipe 42a, the bubble K1 is discharged to the cleaning tank. There was a problem that a predetermined amount of the alkaline water supplied into the inside could not be fed. And when the predetermined amount of alkaline water could not be secured, there was a possibility that cleaning efficiency might also fall.
[0013]
The present invention has been made to solve the above-described problems, and prevents the retention of bubbles generated during electrolysis, and ensures a predetermined amount of electrolyzed water at a desired pH, thereby reducing the cleaning efficiency. It is an object of the present invention to provide a cleaning device that can be prevented and an electric device including the cleaning device.

[0022]
In the figure, reference numeral 1 denotes a cleaning device installed in an electric device such as a dishwasher or a washing machine, for example, a boiler 2 which is a thin cylinder-shaped steam generation and injection device, a power supply 3 for supplying electricity to the boiler 2, and one end.

The other end is connected, for example, a water tap or It is connected, such as a tank, and a water supply passage 8 for supplying water to the electrolyzer 5, and a pump 9 for supplying water to the electrolyzer 5 provided in the middle of the water supply passage 8. Note that the pump 9 may be omitted when the water supply channel 8 is connected to a tap.
[0023]
As shown in FIG. 2, the boiler 2 includes a frame 11 having an evaporation chamber 12 that is a narrow cylindrical space inside, and a heater 13 that is embedded in the frame 11 and heats the frame 11. A first electrolyzed water discharge path 6 having a diameter smaller than the diameter R of the steam chamber 12 is connected to the upstream side that is one side of the steam chamber 12, and the downstream side that is the other side of the boiler 2. The jet passage 4 is connected to the steam chamber 12 and has a diameter smaller than the diameter R of the steam chamber 12. Then, the electrolyzed water (alkaline water) from the electrolyzer 5 sent from the first electrolyzed water discharge path 6 to the boiler 2 is rapidly heated and vaporized by the heater 13, and water droplets are generated using the rapid volume expansion. It sprays from the jet nozzle 4a in the mixed state.
[0024]
As shown in FIG. 3, the electrolyzer 5 includes an electrolytic cell 14 in which a water supply channel 8 is connected to a bottom portion on the upstream side, and an electrolytic cell 14 provided in the center of the electrolytic cell 14 and divided into two in the electrolytic cell 14. A hydrophilic diaphragm 15 forming the

water generation chambers

16, 17; an electrode 18 serving as a cathode and an electrode 19 serving as an anode provided on the inner wall of the electrolyzed

water generation chambers

16, 17 facing the diaphragm 15;

Electric wires

20 and 21 are respectively led out from the

electrodes

18 and 19 and connected to the power source 10 (see FIG. 1), and the first portion is disposed at the top of the electrolytic cell 14 and downstream of the electrolyzed water generation chamber 16. The electrolyzed water discharge path 6 is connected, and the second electrolyzed water discharge path 7 is connected downstream of the electrolyzed water generation chamber 17 at the top of the electrolyzer 14. When a DC voltage (for example, DC 10 V) is applied between the

electrodes

18 and 19, a current flows between the two

electrodes

18 and 19 to electrolyze water in the electrolytic cell 14, and the cathode electrode 18 is provided. Alkaline water that is alkaline electrolyzed water is generated in the electrolyzed water generating chamber 16, and acidic water that is acidic electrolyzed water is generated in the electrolyzed water generating chamber 17 provided with the anode electrode 19. Alkaline water is discharged from the electrolyzed water discharge path 6, and acidic water is discharged from the second electrolyzed water discharge path 7.
[0025]
When the washing apparatus 1 according to the first embodiment configured as described above is provided in, for example, a dishwasher and the dishwasher is driven, the pump 9 of the washing apparatus 1 is also driven and water passes through the water supply path 8. The water that is sent to the electrolyzer 5 and enters the electrolyzer 5 is divided into the electrolyzed

water generation chambers

16 and 17 as shown by the arrows in FIG. The alkaline water and acidic water that have been decomposed and generated in the electrolyzed

water generation chambers

16 and 17 are discharged from the electrolyzed

water discharge passages

6 and 7, respectively. At this time, since the pH of the generated electrolyzed water (alkaline water and acidic water) is proportional to the magnitude of the current flowing through each of the

electrodes

18 and 19, alkaline water having a high pH (acid water having a low pH) is generated. Causes a large amount of current to flow, for example, to allow the current to flow according to the desired pH.
[0026]
Next, the alkaline water discharged to the first electrolyzed water discharge path 6 is sent to the boiler 2, is rapidly heated by the heater 13 of the boiler 2, is vaporized, and dirt (not shown) adheres in a state where water droplets are mixed. It is sprayed at high speed from the spout 4a to tableware or the like. When a predetermined amount of alkaline water is sprayed, the dishwasher supplies water for washing and rinsing from a water supply hose (not shown) into the washing tank, and rinses away alkaline water, etc. removed by reaction with dirt substances from the dishes. Wash and rinse.
[0027]
During the electrolysis of water, gas is generated from the

electrodes

18 and 19 of the electrolyzer 5 of the cleaning device 1, and bubbles expand into the electrolyzed

water generation chambers

16 and 17, and the upper corner of the electrolyzer 14 is not pushed out. The part 14a and the like start to accumulate. Since bubbles are generated while current is flowing between the

electrodes

18 and 19, the remaining bubbles do not disappear as long as the electrolysis is continued. Therefore, the application of voltage between the

electrodes

18 and 19 is temporarily stopped to stop the generation of bubbles, and the bubbles are pushed out of the electrolytic cell 14 by the water passing through the electrolyzed

water generation chambers

16 and 17 to prevent the bubbles from staying. Like that. That is, in the first embodiment, by controlling the voltage (current) applied (flowed) to each of the

electrodes

18 and 19, the retention due to the generated bubbles is prevented and the generation efficiency of the electrolyzed water is prevented from being lowered. Configured.
[0028]
The control of the voltage (current) applied (flowed) between the

electrodes

18 and 19 will be described in detail with reference to FIG.
FIG. 4 is a perspective view of one electrolyzed water generation chamber 16 of the electrolyzer 5, and water entering from the bottom of the electrolyzed water generation chamber 16 is electrolyzed when flowing from bottom to top. During electrolysis, bubbles K are generated in the electrolyzed water generating chamber 16, but the generated bubbles K are faster than the water W that has started to rise in the electrolyzed water generating chamber 16 from the same position simultaneously with the bubbles K due to buoyancy. Ascend in the water. Therefore, the moving speed of the bubbles K in still water is vg [mm / sec], and the moving speed at which a certain water W passes through the electrolyzed water generating chamber 16 is ν [mm / sec] (ν = V / A, V is electrolysis). Assuming that the flow rate of water passing through the water generating chamber 16 and A is the cross-sectional area of the electrolyzed water generating chamber 16, the moving speed of the bubbles K in the water moving in the electrolyzed water generating chamber 16 is the water moving speed ν. Is added, and vg + ν [mm / sec] is obtained. As a result, there is a time difference between the water W and the bubbles K that have started to rise from the same position at the same time in the electrolyzed water generation chamber 16 before exiting the electrolyzed water generation chamber 16.
[0029]
On the other hand, water electrolysis
H₂O + e → 1 / 2H₂ + OH^-
1 / 2H₂O → 1 / 4O₂ + H⁺ + E
H of the generated electrolyzed water⁺Group or OH^-The molar concentration of the group is M [mol / L], the time that the water in the electrolyzed water generating chamber 16 is replaced is T [sec] (T = H / ν, where H is the height of the electrolyzed water generating chamber 16), and electrolysis is performed. If the required amount of electricity is Q [c], the time during which voltage (current) is applied (flowed) is t [sec], and the flowing current is I [A], for example, one H⁺One electron (e) is required to make a group, and the electric quantity of 1 mol of electrons is 96500 [c]. Therefore, to make electrolyzed water of M molar concentration, the electric quantity Q is
Q = M · 96500
It becomes.
[0030]
Further, since the current I and the time t during which the voltage necessary for electrolyzing the water in the electrolyzed water generation chamber 16 is applied are not always constant, the electric quantity Q is expressed by the following equation. The obtained current I is a value obtained by integrating from 0 to time t.
[0031]
[Expression 1]

[0032]
If the current I is constant, the quantity of electricity Q is
Q = I · t
The current I and time t are
I = M · 96500 / t
(1)
[0033]
Here, when the time t during which the voltage is applied is equal to the time T during which the water in the electrolyzed water generation chamber 16 is replaced (t = T), the time from when the water enters the electrolyzed water generation chamber 16 until it exits. Medium electrolysis is performed, and bubbles (gas) are always generated. On the other hand, when the time t during which the voltage is applied is shorter than the time T during which the water in the electrolyzed water generation chamber 16 is replaced (t <T), a certain water W can be brought to a desired molar concentration if the voltage is applied only for the time t. Since it is electrolyzed, it is not necessary to apply a voltage during the time T-t, and no bubbles (gas) are generated during that time.
[0034]
As described above, since there is a time difference between the water W and the bubbles K that have started to rise from the same position in the electrolyzed water generation chamber 16 at the same time, the voltage is applied to the electrodes using this time difference Δt. Is applied, the generated bubbles K (gas) exit from the electrolyzed water generation chamber 16 during the time T-Δt.
That is, the time Tk until the bubble K is generated and exits in the electrolyzed water generation chamber 16 is T · ν / (vg + ν) [sec], and the time difference Δt is T−Tk. Is applied time t,
t = T−Tk = T−T · ν / (vg + ν) = T · vg / (vg + ν)
It becomes.
Then, the voltage is applied only during the time t = T · vg / (vg + ν), and the ON / OFF control of the voltage for stopping the voltage application during the time T−t (Tk) is repeated, whereby the electrolyzed water The bubbles K generated in the generation chamber 16 are discharged while the voltage application is stopped, and the next electrolysis can be performed without the bubbles K in the electrolyzed water generation chamber 16.
[0035]
That is, as shown in FIGS. 5 and 6, the bubble K generated in the electrolyzed water generating chamber 16 is continuously generated during the time t when the voltage is applied ((1) and (2) in FIG. 6). ▼), when the application of voltage is stopped, it does not occur ((3) in FIG. 6), and rises in the electrolyzed water generation chamber 16 during the time Tt when the application of voltage is stopped. It is pushed out by water (alkaline water) ((3) to (5) in FIG. 6) and is generated again during the time t when the voltage is applied ((6) and (7) in FIG. 6). As described above, the bubbles K generated in the electrolyzed water generation chamber 16 are reliably discharged while the voltage application is stopped, and the next electrolysis is performed without staying in the electrolyzed water generation chamber 16. Can do.
[0036]
In addition, when time t = T · vg / (vg + ν) is put into the above equation (A),
I = M · 96500 / {T · vg / (vg + ν)}
In order to obtain electrolyzed water having a desired molar concentration (pH) during the time t when the voltage is applied, the magnitude of the current is determined from the above formula, and when the current of that magnitude continues to flow for the time t, A predetermined amount of electricity is obtained, and electrolyzed water having a desired molar concentration (pH) is obtained.
[0037]
As described above, since there is a difference in the speed at which the bubbles K and the water W pass through the electrolyzed

water generation chambers

16 and 17, a voltage is applied between the

electrodes

18 and 19 during the time difference Δt caused by the speed difference. Since the voltage ON / OFF control is performed, the bubbles K generated during the electrolysis are discharged without staying in the electrolyzed

water generation chambers

16 and 17 when the application of the voltage is stopped. Thus, the use area of the

electrodes

18 and 19 can be prevented from being reduced, a predetermined amount of electricity can be obtained, and the generation efficiency of the electrolyzed water can be prevented from being lowered. Thereby, a predetermined amount of electrolyzed water can be obtained at a desired pH, and a reduction in cleaning efficiency due to the electrolyzed water can be reliably prevented.
[0038]
In the first embodiment, the voltage is applied for the time difference Δt and the voltage application is stopped for the time T−Δt. However, the time for stopping the voltage application is slightly shortened. The voltage may be applied when the bubble K almost comes out of the electrolyzed

water generation chambers

16 and 17, or the voltage application time may be slightly shortened within a range where a predetermined amount of electricity can be obtained. . In these cases, although some bubbles K remain in the upper part of the electrolyzed

water generation chambers

16 and 17, the bubbles K generated by the subsequent electrolysis do not reach the upper part, so that the bubbles K are retained by the rising electrolyzed water. It is surely discharged. Therefore, the same effect is obtained in these cases.
[0039]
Moreover, although the case where the washing | cleaning apparatus 1 was provided in the dishwasher was illustrated and demonstrated in above-mentioned Embodiment 1, you may provide in other electric equipments, such as a washing machine. In this case, the same effect is obtained.
[0040]
Embodiment 2. FIG.
FIG. 7 is a cross-sectional view of the electrolytic cell of the electrolyzer according to Embodiment 2 of the present invention. In the second embodiment, in the electrolytic cell 14 of the electrolyzer 5 according to the first embodiment, the upper corner portion 14a of the inner wall is formed in an arc shape.
[0041]
With this configuration, bubbles generated in the electrolytic cell 14 (electrolyzed water generation chambers 16 and 17) during electrolysis are easily removed from the electrolytic cell 14 and do not easily stay in the upper corner portion 14a. The generation efficiency of electrolyzed water can be prevented from decreasing, and the cleaning efficiency due to electrolyzed water can be reliably prevented from decreasing. In addition, if ON / OFF control of the voltage to the electrolyzer 5 is performed, it is possible to reliably prevent bubbles from staying, prevent a decrease in the generation efficiency of the electrolyzed water due to the bubbles, and reduce the cleaning efficiency due to the electrolyzed water. Can be prevented.
[0042]
In the second embodiment described above, the case where the upper corner portion 14a of the inner wall of the electrolytic cell 14 of the electrolyzer 5 is formed in an arc shape is shown. However, as shown in FIG. You may form the part 14a so that it may incline toward the 1st electrolyzed water discharge path 6 (2nd electrolyzed water discharge path 7) from an inner peripheral wall. In this case, the same effect is obtained.
[0043]
