Description

【0001】
【発明の属する技術分野】
本発明は、被電解水を滞留状態で電気分解して電解水を生成する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はよく知られているが、電解層の水位の確認を行うための配慮がなされていなかった(例えば、特許文献1)。
【0003】
【特許文献1】
特開2002−102853号公報
【0004】
【発明が解決しようとする課題】
しかしながら、前記従来の構成の電解水生成装置においては、電解を行う毎に電解槽内に使用者が水を入れるため、その都度、水位の確認が必要であった。しかし、そのとき水が透明なため電解槽内で水位の確認がしにくく、水が不足した場合には電極が完全に水に浸からないために電極の浸漬した部分のみ電気が流れ、そのため電解が完全に実施できず、また逆に水が多すぎる場合には電解槽から機外に溢れるという課題があった。
【0005】
この課題を解決するため、水位を表示する水位表示ボールを電解槽内の水に浮かせることにより水位を表示することも考えられるが、水道水等を電解すると、原水には各種のイオンが含まれており、特にカルシウムイオンやマグネシウムイオンなどの陽イオンは陰極室の水酸基と反応して水酸化カルシウムや水酸化マグネシウムとなり、溶解限界を超えると陽極や隔膜または水位表示ボールの表面に析出するため、単に水位表示ボールを用いたものではそれ自体が見難くなり、定期的にクエン酸などの薬品を使用し、電解槽内の洗浄を行う必要がある課題がある。
【0006】
本発明は、前記従来の課題を解決するもので、長期間使用してもスケールにより水位表示手段が見難くなることもなく、水位の確認がしやすく、使用性に優れた電解水生成装置を提供することを目的とする。
【0007】
【課題を解決するための手段】
前記目的を達成するために、本発明の電解水生成装置は、陽極室内に水位表示手段を設けたものである。
【0008】
これにより、電解毎に投入される水位は、陽極室に設けた水位表示手段の位置により容易に確認でき、電解槽からの水の溢れが防止できると共に、陽極室内で電解で生じた酸性水には塩素系成分が含まれており、水酸化カルシウムや水酸化マグネシウムなどのスケール成分を溶かす働きがあるため、長期間電解しても水位表示手段にスケールが付着・蓄積せず、定期的にクエン酸などの薬品を使用して電解槽内を洗浄する必要もないため、長期的に快適かつ経済的に使用できる。
【0009】
【発明の実施の形態】
請求項1に記載の発明は、隔膜を介して陽極室と陰極室とを形成し、水を電気分解して電解水を生成する電解槽と、陽極室内の水位表示手段と、陰極室と陽極室を連通する連通手段からなるもので、連通手段によって連通された陰極室と陽極室の水位を、水位表示手段の位置によって容易に確認できると共に、陽極室内で生じた塩素成分を含む酸性水がスケールを溶かすため、水位表示手段周囲にスケールが付着・蓄積することも無く、定期的にクエン酸などの薬品を使用して電解槽内を洗浄する必要もないため、長期的に快適かつ経済的に使用できる。
【0010】
請求項2に記載の発明は、連通手段に電気駆動式の開閉手段を設けたもので、電解槽に水を投入した後、陰極室と陽極室の連通を閉鎖して電解を行うが、連通の開閉を行う開閉手段を、電磁力を用いた電磁弁としたため、一連の電解作業の中で自動的に実施することが可能となり、作業者が手動で行うものと比較し、非常に使いやすいものである。
【0011】
請求項3に記載の発明は、連通手段に設けた開閉手段と、水投入時に開口するフタとを備え、前記フタの閉時に前記開閉手段を閉鎖するもので、電解槽に水を投入した後、フタを閉めるが、そのとき自動的に開閉手段が閉まり、陰極室と陽極室の連通を閉鎖できるため、作業者が意識しないうちに電解工程を進めることができ、非常に使いやすいものである。
【0012】
請求項4に記載の発明は、連通手段に開閉手段を設け、電解溶液を陽極室に送水するとき、前記開閉手段を閉鎖するもので、水を入れて電解を実施するとき、電解を促進する塩や重曹などを溶かした電解溶液を陽極室に投入するが、そのときに自動的に開閉手段が閉まり、陰極室と陽極室の連通を閉鎖できるため、作業者が意識しないうちに電解工程を進めることができ、非常に使いやすいものである。
【0013】
請求項5に記載の発明は、電解終了時に開閉手段を開口するもので、陽極室内で生じた塩素成分を含む酸性水が陰極室内の陰極及び隔膜周辺のスケールを溶かして除去できるため、スケールにより電解時の電流を阻止されることもなく、電解性能が低下しないため、定期的にクエン酸などの薬品を使用して電解槽内を洗浄する必要もなく、長期的に快適に使用できるものである。
【0014】
請求項6に記載の発明は、陰極室で生成されたアルカリ水を吐出する吐出手段を設け、アルカリ水吐出後に開閉手段を開口するもので、陰極室内のアルカリ水を吐出して水位が低下してから酸性水を送水するため、酸性水の方が水位が高く勢いよく早く送水することができると共に、送水した酸性水がアルカリ水で薄くなることが防止できるため、より確実にスケール除去が実施でき、非常に使いやすいものである。
【0015】
請求項7に記載の発明は、中和水貯水手段と、前記中和水貯水手段と連通手段とを連通する連通手段Aと、前記連通手段と前記連通手段Aの接合部に3方弁を設けたもので、水投入時に陰極室と陽極室を連通する動作、電解時などに陽極室と陰極室の連通を解除する動作、電解終了時に陽極室・陰極室の水を中和水貯水手段に送水する動作が3方弁の回転動作のみで選択でき、使いやすいものである。
【0016】
請求項8に記載の発明は、3方弁の操作部を駆動手段で回転するもので、水投入時に陰極室と陽極室を連通する動作、電解時などに陽極室と陰極室の連通を解除する動作、電解終了時に陽極室・陰極室の水を中和水貯水手段に送水する動作が駆動手段で3方弁を回転させることにより選択でき、作業者が操作を行なう必要も無いため、使いやすいものである。
【0017】
請求項9に記載の発明は、陰極室と陽極室の間に上下移動可能な仕切りを設け、フタ開時に仕切りが上方に移動することで陰極室と陽極室が連通し、フタ閉時にフタに付勢され移動し、陰極室と陽極室とを仕切るもので、電解槽に水を投入するとき仕切り下方を通じて陰極室と陽極室が連通し、水位が同じとなりその後フタを閉めるが、そのとき仕切りが下方に移動し自動的に後陰極室と陽極室の連通を解除できるため、作業者が意識しないうちに電解工程を進めることができ非常に使いやすいと共に、連通の制御に開閉手段等の部品を必要とせず、部品点数を削減できるものである。
【0018】
請求項10に記載の発明は、フタ下面と仕切りを一体としたもので、電解槽に水を投入するべくフタを開けたとき、仕切りがフタと一緒に上昇し、仕切り下方を通じて陰極室と陽極室が連通し、両槽の水位が同じとなる。その後フタを閉めるが、そのとき仕切りが下方に移動し自動的に後陰極室と陽極室の連通を閉鎖することとなり、作業者が意識しないうちに電解工程を進めることができ非常に使いやすいと共に、フタと仕切りを1つの部品で構成するため、部品点数の削減に貢献できるものである。
【0019】
【実施例】
以下、本発明の実施例について、図面を参照しながら説明する。
【0020】
(実施例1)
図1〜図6は本発明の実施例1における電解水生成装置を示すものである。
【0021】
図1、図2において、50は水を電気分解して電解水を生成する電解槽であり、陰極室51と陽極室52が並んで構成された配置になっており、前記陽極室52と前記陰極室51は隔膜53を介して分離され、各々陽極54及び陰極55が前記隔膜53を介して対向配置されており、電解時には陽極54には+の電位を負荷し、陰極55には−の電位を負荷する構成になっている。
【0022】
陽極室52底には、陽極水出口56が設けられ、連通管57を介して、陰極室51底に設けられた陰極水出口58と連通され、前記連通管57には送水を制御する開閉手段59が設けられている。
【0023】
60は着脱自在のキャツプ61及び電解質床62を有する電解質タンクであり、ここでは電解質として食塩が充填されている。なお電解質としては、食塩のほかに珪酸塩、炭酸塩、重炭酸塩などの水溶性電解質を用いることができる。電解質タンク60には陰極室51に設けられた給水口63からポンプ64によって電解槽50に入れられた原水が導入路65を経て電解質タンク60の上方に送られる。導入された水は食塩と混合して飽和食塩水となり、電解質床62及び給液路66を通じて電解質供給口67から電解質溶液が陽極室52に供給される構成となっている。
【0024】
ここで、給液路66の電解質供給口67近傍には、陽極室52の原水の進入を阻止する方向に逆止弁68が設けられており、また電解質供給口67は電解質タンク60の液面よりも上方に設けられている。
【0025】
陰極水出口69の上流には、吐出手段70が設けられており、駆動されることで吐出路71を通じて陰極水が吐出口72から電解水容器73に取水される。前記陰極水出口69は陰極室51内方に向けて突出しており、陰極水を取水するとき、陰極水出口69の先端までの水深の陰極水を残す構成になっている。
【0026】
さらに、陰極室51の底に設けられた陰極水出口B74と3方弁75の孔A76が管A77で連通して接続されており、陽極室52底に設けられた陽極水出口B78と3方弁75の孔B79が管B80で連通して接続されており、中和水タンク81と3方弁75の孔C82が管C83で連通して接続されている。3方弁75は、3方弁外84内に3方弁中85が回転自在に挿入されて構成されており、前記3方弁中85には、孔X86と孔Y87が90度の角度を持って内部で貫通するように設けられている。
【0027】
陽極室52内には、リブ88により、比重が1より小さいボールなどよりなる水位表示手段89が陽極室52の水位変化に合わせて上下に移動可能に設けられている。
【0028】
次に本実施例の構成における動作、作用を説明する。
【0029】
開閉手段59を開けて電解槽50に水を入れると、陰極室51と陽極室52内で同じ水位を保ちながら水が増し、そのため水位表示手段89が上昇し、水位確認が非常に行いやすいこととなる。
【0030】
所定の位置まで水が入った状態で開閉手段59を閉じてスイッチ(図示せず)を投入すると、まずポンプ64が所定時間だけ駆動され、陰極室51の原水が導入路65を経て電解質タンク60に送られる。電解室タンク60は水密状態に構成されており、原水が導入されることにより、過飽和状態の食塩水が電解質床62、給液路66、逆止弁68を経て電解質供給口67から陽極室51内に所定量供給され、所定濃度の食塩希釈水となる。ついで陽極54を+極、及び陰極55を−極として所定時間通電され、電解動作が開始される。電解時の陽極室52では、(化1)に示した反応が生じて酸性水が生成される。
【0031】
【化1】

Figure 2004181386
【0032】
この酸性水には塩素成分が含まれており、水位表示手段89に付着する水酸化カルシウムや水酸化マグネシウムなどのスケール成分を溶かす働きがあるため、スケール成分が溶解除去され、長期間使用した場合などでも堆積したスケールにより水位表示手段89が見難くなることが無く、クエン酸などの薬品を使用して電解槽50を洗浄する必要も生じず、長期的に使用性が保持できるものである。
【0033】
一方、陰極室51では、(化2)に示した反応が生じて水酸基OHを中和するためNaが隔膜51を通過して移動し、アルカリ水が生成される。
【0034】
【化2】
Figure 2004181386
【0035】
ここで、陽極室52のみ食塩溶液が供給されるので、短時間に還元力の強いアルカリ水が得られる。すなわち、陽極54と陰極55間に電圧が印加されると被電解水に含まれるイオンは電気吸引力により陽/陰極54、55と逆極性のイオンが隔膜53を通過して移動することとなる。したがって陽極室52に導入された食塩に含まれるNaイオンは隔膜53を経て陰極室51へと即座に移動する。この電気吸引力以外にも例えば拡散理論にしたがえば、Naイオンが拡散によってイオン濃度を均一にするように作用する。この結果、陽/陰極54、55間に流れる電流が増加し、短時間に還元力の強いアルカリ水が得られる。この還元力の強いアルカリ水は、油脂の鹸化や乳化作用および蛋白質に対する加水分解作用を有し、家具や住宅建材、電気製品などの表面の洗浄水として利用できる。
【0036】
また、陽極室52のみに食塩溶液が供給されることで、陰極室51には塩素イオンCl濃度の低いアルカリ水が生成される。Clは洗浄力を阻害する因子となるため、陽極室52のみに食塩溶液が供給されることで、洗浄力の強いアルカリ水が生成できる。
【0037】
陰極室51にて生成されたアルカリ水は、所定時間電解された後、直ちに吐水手段70が駆動され、吐出路71を通じて、陰極水出口69の先端までの水深の量を陰極室51内に残し、吐出口72から電解水容器73に注入される。これにより電解隔膜を介しての酸性水とアルカリ水の浸透混入が防止でき、pH値の劣化が防止できるものである。なお電解水容器73には噴霧機構(図示せず)を設けて被洗浄面に直接スプレー噴霧して使用することもできる。
【0038】
次に、孔Y87と中和水タンク76が連通する方向に3方弁75内の3方弁中85を回転させ、陰極水出口B74と陽極水出口B78と中和水タンク76を連通させることにより、酸性水とアルカリ水を混合させた中和水を中和水タンク76に送水することができる。この中和水は、塩素成分を含んだ状態で、且つ中性もしくは弱酸性の性質を示し、殺菌水や茶渋等の漂白などに使用することができる。
【0039】
このとき、図3に示すように、連通管57に電磁弁等の開閉手段90を設けることにより、一連の電解作業の中で自動的に水投入後の連通管57の閉塞作業が行えることとなり、作業者が手動で行うものと比較し、非常に使いやすいものが構成可能となる。
【0040】
例えば、図4に示すように、水を入れるときに開くフタ91の回転中心92近傍にリミットスイッチ93を設け、前記フタ91を閉めたときにフタ91でリミットスイッチ93を附勢し(図4(a))、その信号にて開閉手段90を閉鎖した場合など、フタ91を閉めただけで陰極室51と陽極室52の連通を解除でき、非常に使いやすいものとなる。
【0041】
また、電解液を送水するポンプ64が動き出した信号にて開閉手段90を閉鎖した場合についても、作業者が意識しないうちに電解工程を進めることができ、非常に使いやすいものとなる。
【0042】
さらに、電解終了後に開閉手段90を開けることにより(図4(b))、陽極室52内で生成した酸性水が陰極室51に送水され、陰極室51内に塩素成分の含まれた酸性水が流入することにより、陰極55および隔膜53に付着堆積した水酸化カルシウムや水酸化マグネシウムなどのスケール成分を溶かす働きがあるため、スケール成分が溶解除去され、長期間使用した場合などでも堆積したスケールにより電解電流の通電が阻害されることが無く、クエン酸などの薬品を使用して電解槽50を洗浄する必要も生じず、長期的に安定したpHの電解水を生成できるため、快適かつ経済的に長期間使用できる。
【0043】
また、吐出手段70により、陰極室51内で生成されたアルカリ水を電解水容器73に送水した後に開閉手段90を開けることにより、酸性水の水位がアルカリ水の水位よりも高い状態で送水することとなり、勢いよく早く送水することができると共に、送水した酸性水がアルカリ水で薄くなることを防止できるため、より確実にスケール除去が実施でき、非常に使いやすいものとなる。
【0044】
また、図5及び図6においては、陰極室51の陰極水出口58と3方弁B94の孔D95が管D96で連通して接続され、陽極室52の陽極水出口56と3方弁B94の孔E97が管E98で連通して接続され、中和水タンク81と3方弁B94の孔F99が管F100で連通して接続されている。3方弁B94は、3方弁B外101内に3方弁B中102が回転自在に挿入されて構成されており、前記3方弁B中102には、孔V103と孔W104が90度の角度を持って内部で貫通するように設けられている。
【0045】
この場合では、水を投入するときに陰極室51と陽極室52の連通を行う動作、電解するときに陰極室51と陽極室52の連通を解除する動作、陰極室51の酸性水と陰極室のアルカリ水を中和水タンク81に送水する動作が3方弁の回転動作のみで選択でき、使いやすいものとなる。
【0046】
また、3方弁B中102(操作部)をモーター等の駆動手段で回転させることにより、一連の動作を自動で行うことができ、作業者が3方弁B中102を手動で回転させることと比較し使いやすいものである。
【0047】
(実施例2)
次に、本発明の実施例2における電解水生成装置について、図7、図8を用いて説明する。なお、実施例1と同一構成部品には同一符号を付与し、その説明を省略する。
【0048】
図7に示すように、隔膜53を中央に配し、前記隔膜53を介して陽極54及び陰極55が左右に対向配置された仕切り105が電解槽50内で上下移動可能に設けられており、仕切り105によって陰極室51及び陽極室52が仕切られている。仕切り105はバネ等(図示せず)にて常時上方に附勢され、フタ91を開けると電解槽50との間に隙間が生じることによって陰極室51と陽極室52の間が連通し(図7(b))、フタ91を閉めるとフタ91下面が仕切り105を下方に付勢し、仕切り105と電解槽50との隙間が塞がれることにより(図7(a))、陰極室51と陽極室52の連通が閉鎖される構成となっている。
【0049】
次に本実施例の構成における動作、作用を説明する。
【0050】
フタ91を開けて電解槽50に水を入れると、仕切り105と電解槽50との隙間で陰極室51と陽極室52が連通しているため、両槽で同じ水位を保ちながら水が増え、そのため水位表示手段89が上昇し、水位確認が非常に行いやすく、所定の位置まで水が入った状態でフタ91を閉めると、仕切り105と電解槽50との隙間が閉じられ、陰極室51と陽極室52の連通が閉鎖されるため、電解を行っても電解槽内で酸性水とアルカリ水が混ざることが防止でき、開閉手段や電磁弁等を使用して機器を構成した場合と比較し、部品点数も少なく、安価に構成できるものである。
【0051】
また、図8に示すように、仕切り105をフタ91の裏面に一体に構成した場合では、フタ91を開けたときには一緒に仕切り105が上昇し、陰極室51と陽極室52を連通させることができ(図8(b))、フタ91を閉めたときには仕切り105が下降し、陰極室51と陽極室52の連通を閉鎖させることができ(図8(a))、この場合においても開閉手段や電磁弁等を用いた連通機構が不用となり、部品点数が削減できるため、安価に機器が構成できる。
【0052】
上記した各実施例1、2に示した構成は、必要に応じて適宜組み合わせて構成することができるものであり、実施例そのものに限られるものではない。
【0053】
【発明の効果】
以上のように、本発明の電解水生成装置によれば、電解毎に投入される水位は、陽極室に設けた水位表示手段の位置により容易に確認でき、電解槽からの水の溢れが防止できると共に、陽極室内で電解で生じた酸性水には塩素系成分が含まれており、水酸化カルシウムや水酸化マグネシウムなどのスケール成分を溶かす働きがあるため、長期間電解しても水位表示手段にスケールが付着・蓄積せず、定期的にクエン酸などの薬品を使用して電解槽内を洗浄する必要もないため、長期的に快適かつ経済的に使用できる。

[0002]
[Prior art]
Conventionally, this type of electrolyzed water generating apparatus is well known, but no consideration has been given to checking the water level of the electrolytic layer (for example, Patent Document 1).
[0003]
[Patent Document 1]
JP-A-2002-102853
[Problems to be solved by the invention]
However, in the electrolyzed water generating apparatus having the above-described configuration, the user needs to check the water level every time since the user puts water into the electrolytic cell every time electrolysis is performed. However, at that time, it is difficult to check the water level in the electrolytic cell because the water is transparent, and when the water is insufficient, the electrode is not completely immersed in the water, so electricity flows only in the part where the electrode is immersed. However, when the amount of water is too large, there is a problem that the water overflows from the electrolytic cell to the outside of the apparatus.
[0005]
To solve this problem, it is conceivable to display the water level by floating a water level display ball that displays the water level on the water in the electrolytic cell.However, when tap water is electrolyzed, the raw water contains various ions. In particular, cations such as calcium ions and magnesium ions react with hydroxyl groups in the cathode chamber to form calcium hydroxide and magnesium hydroxide, and when exceeding the solubility limit, precipitate on the surface of the anode, diaphragm or water level display ball, There is a problem that it is difficult to see itself using the water level indicating ball, and it is necessary to periodically use a chemical such as citric acid to wash the inside of the electrolytic cell.
[0006]
The present invention solves the above-mentioned conventional problems, and does not make the water level display means difficult to see due to the scale even when used for a long period of time. The purpose is to provide.

[Means for Solving the Problems]
In order to achieve the above object, the electrolyzed water generation device of the present invention has a water level display means provided in the anode chamber.
[0008]
Thereby, the water level charged for each electrolysis can be easily confirmed by the position of the water level display means provided in the anode chamber, and the overflow of water from the electrolytic cell can be prevented, and the acid water generated by electrolysis in the anode chamber can be prevented. Contains chlorine-based components and has the effect of dissolving scale components such as calcium hydroxide and magnesium hydroxide. Since there is no need to clean the inside of the electrolytic cell using a chemical such as an acid, it can be used comfortably and economically for a long time.
[0009]

According to the first aspect of the present invention, there is provided an electrolytic cell for forming an anode chamber and a cathode chamber through a diaphragm, electrolyzing water to generate electrolyzed water, a water level display means in the anode chamber, a cathode chamber and an anode. The water level of the cathode chamber and the anode chamber communicated by the communication means can be easily confirmed by the position of the water level display means, and the acidic water containing chlorine component generated in the anode chamber can be easily confirmed by the position of the water level display means. Since the scale is dissolved, the scale does not adhere or accumulate around the water level indicating means, and there is no need to periodically clean the inside of the electrolytic cell using a chemical such as citric acid. Can be used for
[0010]
According to the second aspect of the present invention, the communication means is provided with an electrically driven opening / closing means. After water is charged into the electrolytic cell, the communication between the cathode chamber and the anode chamber is closed to perform electrolysis. The opening / closing means that opens and closes is an electromagnetic valve that uses electromagnetic force, so that it can be performed automatically during a series of electrolysis operations, and is very easy to use as compared to manual operations performed by workers. Things.

The introduced water is mixed with salt to form a saturated saline solution, and the electrolyte solution is supplied to the anode chamber 52 from the electrolyte supply port 67 through the electrolyte bed 62 and the liquid supply path 66.
[0024]
Here, a check valve 68 is provided near the electrolyte supply port 67 of the liquid supply passage 66 in a direction for preventing the entry of raw water into the anode chamber 52, and the electrolyte supply port 67 is connected to the liquid level of the electrolyte tank 60. It is provided above.
[0025]
A discharge means 70 is provided upstream of the cathode water outlet 69, and the cathode water is taken from the discharge port 72 into the electrolytic water container 73 through the discharge path 71 by being driven. The cathode water outlet 69 protrudes toward the inside of the cathode chamber 51, and has a configuration in which the cathode water at a depth up to the tip of the cathode water outlet 69 is left when the cathode water is taken.
[0026]
Further, a cathode water outlet B74 provided at the bottom of the cathode chamber 51 and a hole A76 of the three-way valve 75 are communicated and connected by a pipe A77, and are connected to the anode water outlet B78 provided at the bottom of the anode chamber 52 at three sides. The hole B79 of the valve 75 is connected and connected by a pipe B80, and the hole C82 of the three-way valve 75 is connected and connected by a pipe C83.

[0027]
In the anode chamber 52, a water level indicator 89 such as a ball having a specific gravity smaller than 1 is provided by a rib 88 so as to be movable up and down in accordance with a change in the water level of the anode chamber 52.
[0028]
Next, the operation and operation of the configuration of the present embodiment will be described.
[0029]
When the opening / closing means 59 is opened and water is poured into the electrolytic cell 50, the water increases while maintaining the same water level in the cathode chamber 51 and the anode chamber 52, so that the water level display means 89 rises, and it is very easy to confirm the water level. It becomes.
[0030]
When a switch (not shown) is turned on by closing the opening / closing means 59 in a state where water has entered into a predetermined position, first, the pump 64 is driven for a predetermined time, and the raw water in the cathode chamber 51 is supplied through the introduction path 65 to the electrolyte tank 60.

[0032]
Since the acidic water contains a chlorine component and has a function of dissolving scale components such as calcium hydroxide and magnesium hydroxide attached to the water level indicating means 89, the scale component is dissolved and removed, and when used for a long time. Even if the scale is deposited, the water level display means 89 is not obstructed, and there is no need to clean the electrolytic cell 50 using a chemical such as citric acid, so that the usability can be maintained for a long time.
[0033]
On the other hand, in the cathode chamber 51, the reaction shown in (Chem. 2) occurs, and Na + moves through the diaphragm 51 to neutralize the hydroxyl group OH , and alkaline water is generated.
[0034]

Figure 2004181386
[0035]
Here, since the salt solution is supplied only to the anode chamber 52, alkaline water having a strong reducing power can be obtained in a short time. That is, when a voltage is applied between the anode 54 and the cathode 55, the ions contained in the water to be electrolyzed move in the opposite direction to the positive / negative electrodes 54 and 55 through the diaphragm 53 due to the electric attraction. . Therefore, Na ions contained in the salt introduced into the anode chamber 52 immediately move to the cathode chamber 51 via the diaphragm 53. In addition to the electric attraction force, for example, according to the diffusion theory, Na ions act to make the ion concentration uniform by diffusion. As a result, the current flowing between the positive / negative electrodes 54 and 55 increases, and alkaline water having a strong reducing power can be obtained in a short time. The alkaline water having a strong reducing power has a saponifying or emulsifying action on fats and oils and a hydrolyzing action on proteins, and can be used as washing water for surfaces of furniture, house building materials, electric appliances and the like.
[0036]
Further, by supplying the salt solution only to the anode chamber 52, alkaline water having a low concentration of chlorine ion Cl is generated in the cathode chamber 51. Since Cl is a factor that inhibits the detergency, by supplying the salt solution only to the anode chamber 52, alkaline water having a strong detergency can be generated.
[0037]
Immediately after the alkaline water generated in the cathode chamber 51 is electrolyzed for a predetermined time, the water discharging means 70 is driven to leave the amount of water depth up to the tip of the cathode water outlet 69 through the discharge path 71 in the cathode chamber 51. , From the discharge port 72 into the electrolytic water container 73. Thereby, permeation and mixing of acidic water and alkaline water through the electrolytic membrane can be prevented, and deterioration of the pH value can be prevented. The electrolyzed water container 73 may be provided with a spray mechanism (not shown) so that it can be sprayed directly onto the surface to be cleaned.
[0038]
Next, by rotating the three-way valve 85 in the three-way valve 75 in the direction in which the hole Y87 and the neutralizing water tank 76 communicate with each other, the cathode water outlet B74, the anode water outlet B78, and the neutralizing water tank 76 communicate with each other. Thereby, the neutralized water obtained by mixing the acidic water and the alkaline water can be sent to the neutralized water tank 76. This neutralized water contains a chlorine component and exhibits a neutral or weakly acidic property, and can be used for bleaching of sterilized water or tea astringent.
[0039]
At this time, as shown in FIG. 3, by providing the opening / closing means 90 such as an electromagnetic valve in the communication pipe 57, it is possible to automatically close the communication pipe 57 after water injection in a series of electrolysis operations. This makes it possible to construct a device that is very easy to use as compared with a device that is manually operated by an operator.
[0040]
For example, as shown in FIG. 4, a limit switch 93 is provided near the rotation center 92 of the lid 91 which is opened when water is poured, and the limit switch 93 is urged by the lid 91 when the lid 91 is closed (FIG. 4). (A)) The communication between the cathode chamber 51 and the anode chamber 52 can be released only by closing the lid 91, for example, when the opening / closing means 90 is closed by the signal, which makes the apparatus very easy to use.
[0041]
Also, even when the opening / closing means 90 is closed by a signal from which the pump 64 for feeding the electrolyte starts to move, the electrolysis process can proceed without the worker being conscious of the operation, which is very easy to use.
[0042]
Further, by opening the opening / closing means 90 after the electrolysis is completed (FIG. 4B), the acidic water generated in the anode chamber 52 is sent to the cathode chamber 51, and the acidic water containing a chlorine component is contained in the cathode chamber 51. Has the effect of dissolving scale components such as calcium hydroxide and magnesium hydroxide adhered and deposited on the cathode 55 and the diaphragm 53, so that the scale components are dissolved and removed, and the scale deposited even when used for a long time is used. Therefore, it is not necessary to wash the electrolytic cell 50 using a chemical such as citric acid, and it is possible to generate electrolyzed water having a stable pH for a long period of time. It can be used for a long period of time.
[0043]
In addition, after the alkaline water generated in the cathode chamber 51 is supplied to the electrolytic water container 73 by the discharge means 70 and the opening / closing means 90 is opened, the acidic water is supplied in a state where the level of the acidic water is higher than the level of the alkaline water. As a result, the water can be quickly and quickly supplied, and the supplied acidic water can be prevented from being diluted with the alkaline water. Therefore, the scale can be more reliably removed and the device is very easy to use.
[0044]
In FIGS. 5 and 6, the cathode water outlet 58 of the cathode chamber 51 and the hole D95 of the three-way valve B94 are communicated and connected by a pipe D96, and the anode water outlet 56 of the anode chamber 52 is connected to the three-way valve B94. The hole E97 is communicated and connected by a tube E98, and the hole F99 of the neutralizing water tank 81 and the three-way valve B94 are communicated and connected by a tube F100. The three-way valve B94 is configured such that the three-way valve B 102 is rotatably inserted into the outside 101 of the three-way valve B, and the three-way valve B 102 has a hole V103 and a hole W104 at 90 degrees. Is provided so as to penetrate the inside at an angle.
[0045]
In this case, the operation of communicating the cathode chamber 51 and the anode chamber 52 when water is supplied, the operation of releasing the communication between the cathode chamber 51 and the anode chamber 52 during electrolysis, the operation of the acidic water of the cathode chamber 51 and the cathode chamber The operation of supplying the alkaline water to the neutralized water tank 81 can be selected only by the rotation operation of the three-way valve, and is easy to use.
[0046]
In addition, a series of operations can be automatically performed by rotating the 102 (operation unit) of the three-way valve B by driving means such as a motor, and the operator can manually rotate the 102 of the three-way valve B. It is easy to use compared to.
[0047]
(Example 2)
Next, an electrolyzed water generating apparatus according to a second embodiment of the present invention will be described with reference to FIGS. The same components as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.
[0048]
As shown in FIG. 7, a diaphragm 105 is disposed at the center, and a partition 105 in which an anode 54 and a cathode 55 are disposed to face left and right via the diaphragm 53 is provided so as to be movable up and down in the electrolytic cell 50. The cathode chamber 51 and the anode chamber 52 are partitioned by the partition 105. The partition 105 is constantly urged upward by a spring or the like (not shown). When the lid 91 is opened, a gap is formed between the electrolytic chamber 50 and the cathode chamber 51 and the anode chamber 52 communicate with each other (see FIG. 7 (b)), when the lid 91 is closed, the lower surface of the lid 91 urges the partition 105 downward, and the gap between the partition 105 and the electrolytic cell 50 is closed (FIG. 7 (a)). And the anode chamber 52 are closed.
[0049]
Next, the operation and operation of the configuration of the present embodiment will be described.
[0050]
When the lid 91 is opened and water is poured into the electrolytic cell 50, since the cathode chamber 51 and the anode chamber 52 communicate with each other in the gap between the partition 105 and the electrolytic cell 50, the amount of water increases while maintaining the same water level in both cells. Therefore, the water level display means 89 rises, and it is very easy to check the water level. When the lid 91 is closed in a state where water has been filled to a predetermined position, the gap between the partition 105 and the electrolytic cell 50 is closed, and the cathode chamber 51 is closed. Since the communication between the anode chambers 52 is closed, it is possible to prevent the acidic water and the alkaline water from being mixed in the electrolytic cell even when the electrolysis is performed, as compared with a case where the device is configured using an opening / closing means or a solenoid valve. In addition, the number of parts is small, and it can be constructed at low cost.
[0051]
As shown in FIG. 8, when the partition 105 is integrally formed on the back surface of the lid 91, when the lid 91 is opened, the partition 105 rises together to connect the cathode chamber 51 and the anode chamber 52. When the lid 91 is closed (see FIG. 8B), the partition 105 is lowered, and the communication between the cathode chamber 51 and the anode chamber 52 can be closed (FIG. 8A). Since a communication mechanism using a valve or a solenoid valve is not required, and the number of parts can be reduced, the device can be configured at low cost.
[0052]
The configuration shown in each of the first and second embodiments can be appropriately combined as needed, and is not limited to the embodiment itself.
[0053]
