ところで、このような電解水生成装置にあっては、水に溶解している例えばＣａＣＯ３やＭｇ（ＯＨ）２等の成分が析出して電解槽１０５の陰極通水路１２５や陽極通水路１２６などに固着し、それらの通水路１２５，１２６が徐々に閉塞されてしまい、電解水生成装置の寿命が短命化するという問題がある。 By the way, in such an electrolyzed water generating apparatus, components such as CaCO 3 and Mg (OH) 2 dissolved in water are deposited, and the cathode water passage 125 and the anode water passage 126 of the electrolytic cell 105 are used. The water passages 125 and 126 are gradually blocked, and there is a problem that the life of the electrolyzed water generating device is shortened.

そこで、本発明は、電解水生成装置の長寿命化を図ることを目的とする。   Then, this invention aims at extending the lifetime of an electrolyzed water generating apparatus.

本発明の第１の態様は、隔膜と、この隔膜を間にして相互に対向配置された一対の電極板と、前記電極板と前記隔膜との間を通る一対の通水路と、を備え、前記一対の電極板間に電圧を印加して、前記通水路を流れる水から電解水を生成する電解水生成装置において、前記通水路の通水方向での前記隔膜の両端部を保持するとともに前記通水路の路面を構成する保持部材と、前記通水路の通水方向での前記保持部材における両端部に設けられ、前記隔膜と電極板との間の距離を規定する複数の規定部と、を備え、前記通水路の通水方向での前記保持部材の下流側端部の前記隔膜に接続された部分であって前記通水路の路面を構成する部分における前記隔膜の厚さ方向での厚さが、前記隔膜の厚さ以下であること特徴とする。   A first aspect of the present invention includes a diaphragm, a pair of electrode plates disposed opposite to each other with the diaphragm interposed therebetween, and a pair of water passages passing between the electrode plate and the diaphragm, In the electrolyzed water generating device that generates electrolyzed water from the water flowing through the water channel by applying a voltage between the pair of electrode plates, while holding both ends of the diaphragm in the direction of water flow of the water channel A holding member that constitutes a road surface of the water passage, and a plurality of defining portions that are provided at both ends of the holding member in the water passage direction of the water passage and that define the distance between the diaphragm and the electrode plate. A thickness in the thickness direction of the diaphragm in a portion connected to the diaphragm at a downstream end portion of the holding member in the water flow direction of the water flow path and constituting a road surface of the water flow path Is less than or equal to the thickness of the diaphragm.

本発明の第２の態様は、隔膜と、この隔膜を間にして相互に対向配置された一対の電極板と、前記電極板と前記隔膜との間を通る一対の通水路と、を備え、一対の前記電極板間に電圧を印加して、前記通水路を流れる水から電解水を生成する電解水生成装置において、前記通水路の通水方向での前記隔膜の両端部を保持するとともに前記通水路の路面を構成する保持部材と、前記通水路の通水方向での前記保持部材における両端部に設けられ、前記隔膜と電極板との間の距離を規定する複数の規定部と、を備え、前記通水路の通水方向での前記保持部材における下流側の端部には、相互に間隔をあけて配置された２つの前記規定部が設けられており、前記保持部材の下流側の端部における２つの前記規定部間には、前記隔膜の一部が配置された凹部が形成されており、前記凹部内に位置する前記隔膜が前記通水路の路面を構成していることを特徴とする。   The second aspect of the present invention comprises a diaphragm, a pair of electrode plates disposed opposite to each other with the diaphragm interposed therebetween, and a pair of water passages passing between the electrode plate and the diaphragm, In an electrolyzed water generating device that generates electrolyzed water from water flowing through the water flow path by applying a voltage between the pair of electrode plates, while holding both ends of the diaphragm in the water flow direction of the water flow path A holding member that constitutes a road surface of the water passage, and a plurality of defining portions that are provided at both ends of the holding member in the water passage direction of the water passage and that define the distance between the diaphragm and the electrode plate. Two downstream end portions of the holding member in the direction of water flow of the water passage are provided with the two defining portions spaced apart from each other, and on the downstream side of the holding member A portion of the diaphragm is disposed between the two defining portions at the end. A recessed portion is formed, wherein the diaphragm is located in the recess constitutes the road surface of the water passage.

本発明の第３の態様は、前記第１又は第２の態様の電解水生成装置において、前記保持部材は、前記隔膜に向かうにしたがい厚さが薄くなるように形成された傾斜部を有することを特徴とする。   According to a third aspect of the present invention, in the electrolyzed water generating apparatus according to the first or second aspect, the holding member has an inclined portion formed such that the thickness becomes thinner toward the diaphragm. It is characterized by.

本発明の前記第１の態様によれば、通水路の通水方向での保持部材の下流側端部の隔膜に接続された部分であって通水路の路面を構成する部分における隔膜の厚さ方向での厚さが、隔膜の厚さ以下であることにより、前記部分の厚さが隔膜の厚さよりも厚い場合に比べて、通水路の断面積を広くとることができるので、その分、水からの析出成分の固着による通水路の閉塞を抑制することができ、ひいては電解水生成装置の長寿命化を図ることができる。   According to the first aspect of the present invention, the thickness of the diaphragm in the portion connected to the diaphragm at the downstream end of the holding member in the direction of passage of the water passage and constituting the road surface of the water passage. Since the thickness in the direction is equal to or less than the thickness of the diaphragm, the cross-sectional area of the water passage can be made wider than in the case where the thickness of the portion is larger than the thickness of the diaphragm. The blockage of the water passage due to the adhesion of the precipitated components from water can be suppressed, and as a result, the life of the electrolyzed water generating device can be extended.

本発明の前記第２の態様によれば、保持部材の下流側の端部における２つの規定部間には、隔膜の一部が配置された凹部が形成されており、凹部内に位置する隔膜が通水路の路面を構成していることによって、保持部材に凹部が形成されていない場合に比べて、保持部材の下流側の端部における２つの規定部間での通水路の断面積を広くとることができるので、その分、水からの析出成分の固着による通水路の閉塞を抑制することができ、ひいては電解水生成装置の長寿命化を図ることができる。   According to the second aspect of the present invention, a recess in which a part of the diaphragm is disposed is formed between the two defining portions at the downstream end of the holding member, and the diaphragm is located in the recess. By configuring the road surface of the water passage, the cross-sectional area of the water passage between the two defining portions at the end portion on the downstream side of the holding member is wider than when the concave portion is not formed in the holding member. Therefore, it is possible to suppress the blockage of the water passage due to the adhesion of the precipitated component from the water, thereby extending the life of the electrolyzed water generating device.

本発明の前記第３の態様によれば、保持部材が傾斜部を有するので、保持部材の強度剛性の確保と、通水路の断面積の拡大化との両立を図ることができる。   According to the third aspect of the present invention, since the holding member has the inclined portion, it is possible to achieve both of ensuring the strength and rigidity of the holding member and enlarging the cross-sectional area of the water passage.

保持部材２４ｅは、細長く形成された一対の側壁部２４ｈと、これらの一対の側壁部２４ｈ同士を連結した一対の連結部２４ｉとを有している。保持部材２４ｅは、陰極通水路２５の路面および陽極通水路２６の路面を構成している。   The holding member 24e has a pair of elongated side wall portions 24h and a pair of connecting portions 24i that connect the pair of side wall portions 24h.

連結部２４ｉは、側壁部２４ｈよりも薄く形成されている。連結部２４ｉは、保持部材２４ｅの外周部を構成する厚肉部２４ｊと、保持部材２４ｅの内周部を構成する薄肉部２４ｋとを有している。薄肉部２４ｋは、隔膜２３の厚さ方向での厚さが厚肉部２４ｊよりも薄く形成されている。これらの連結部２４ｉの相互に対向する面に隔膜２３の端部が例えば接着などによって固定されている。これによって、保持部材２４ｅは、陰極通水路２５および陽極通水路２６の通水方向での隔膜２３の両端部を保持している。   The connecting part 24i is formed thinner than the side wall part 24h. The connecting portion 24i has a thick portion 24j that forms the outer peripheral portion of the holding member 24e, and a thin portion 24k that forms the inner peripheral portion of the holding member 24e. The thin part 24k is formed so that the thickness of the diaphragm 23 in the thickness direction is thinner than the thick part 24j. The end portions of the diaphragm 23 are fixed to the mutually facing surfaces of the connecting portions 24i by, for example, adhesion. Thus, the holding member 24e holds both end portions of the diaphragm 23 in the water flow direction of the cathode water passage 25 and the anode water passage 26.

規定部２４ｆは、陰極通水路２５および陽極通水路２６の通水方向での保持部材２４ｅにおける両端部（上流側端部および下流側端部）に設けられて隔膜２３と電極板（陰極通水路２５および陽極通水路２６）との間の距離を規定するとともに、陰極通水路２５の路面および陽極通水路２６の路面を構成するものである。具体的には、規定部２４ｆは、薄肉部２４ｋにおける側壁部２４ｈに接続された各端部に設けられている。より詳細には、規定部２４ｆは、薄肉部２４ｋにおける陰極板２１と対向する面と、陽極板２２と対向する面とにそれぞれ形成されている。即ち、保持部材２４ｅの両面の４隅部に一つずつ規定部２４ｆが設けられている。この規定部２４ｆは、連結部２４ｉとは別部品として成形して連結部２４ｉに固着させてもよいし、連結部２４ｉに一体成形しても良い。図面では、規定部２４ｆが、連結部２４ｉとは別部品として成形されて連結部２４ｉに固着された例が示されている。   The defining portion 24f is provided at both end portions (upstream end portion and downstream end portion) of the holding member 24e in the water flow direction of the cathode water passage 25 and the anode water passage 26, and the diaphragm 23 and the electrode plate (cathode water passage). 25 and the anode water passage 26), and the road surface of the cathode water passage 25 and the road surface of the anode water passage 26 are configured. Specifically, the defining portion 24f is provided at each end portion connected to the side wall portion 24h in the thin portion 24k. More specifically, the defining portion 24f is formed on a surface facing the cathode plate 21 and a surface facing the anode plate 22 in the thin portion 24k. That is, one defining portion 24f is provided at each of the four corners of the holding member 24e. The defining portion 24f may be molded as a separate part from the connecting portion 24i and fixed to the connecting portion 24i, or may be integrally formed with the connecting portion 24i. In the drawing, an example is shown in which the defining portion 24f is molded as a separate part from the connecting portion 24i and is fixed to the connecting portion 24i.

一対の押さえ板２４ｇは、側壁部２４ｈに固定されて保持部材２４ｅの開口を閉塞する。一方の押さえ板２４ｇと保持部材２４ｅの一方の面に設けられた４つの規定部２４ｆとの間に陰極板２１が配置されて、その一方の押さえ板２４ｇと４つの規定部２４ｆとが陰極板２１を挟持している。また、他方の押さえ板２４ｇと保持部材２４ｅの他方の面に設けられた４つの規定部２４ｆとの間に陽極板２２が配置されて、その他方の押さえ板２４ｇと４つの規定部２４ｆとが陽極板２２を保持している。なお、図３および図４では、押さえ板２４ｇは省略されている。   The pair of pressing plates 24g is fixed to the side wall portion 24h and closes the opening of the holding member 24e. The cathode plate 21 is disposed between one pressing plate 24g and the four defining portions 24f provided on one surface of the holding member 24e, and the one pressing plate 24g and the four defining portions 24f are connected to the cathode plate. 21 is sandwiched.

The anode plate 22 is held. In FIG. 3 and FIG. 4, the holding plate 24g is omitted.

そして、一方の連結部２４ｉと陰極板２１の一端部と陰極板２１の一端部を支持する２つの規定部２４ｆとによって、陰極通水路２５の第一流入口２４ａが形成され、他方の連結部２４ｉと陰極板２１の他端と陰極板２１の他端部を支持する２つの規定部２４ｆとによって、陰極通水路２５の第一流出口２４ｃが形成されている。また、一方の連結部２４ｉと陽極板２２の一端部と陽極板２２の一端部を支持する２つの規定部２４ｆとによって陽極通水路２６の第二流入口２４ｂが形成され、他方の連結部２４ｉと陽極板２２の他端と陽極板２２の他端部を支持する２つの規定部２４ｆとによって、陽極通水路２６の第二流出口２４ｄが形成されている。   The first inlet 24a of the cathode water passage 25 is formed by one connecting portion 24i, one end portion of the cathode plate 21, and two defining portions 24f that support one end portion of the cathode plate 21, and the other connecting portion 24i. The first outlet 24 c of the cathode water passage 25 is formed by the other end of the cathode plate 21 and the two defining portions 24 f that support the other end of the cathode plate 21. Moreover, the second inflow port 24b of the anode water passage 26 is formed by one connecting portion 24i, one end portion of the anode plate 22, and two defining portions 24f supporting one end portion of the anode plate 22, and the other connecting portion 24i. The second outlet 24 d of the anode water passage 26 is formed by the other end of the anode plate 22 and the two defining portions 24 f that support the other end of the anode plate 22.

そして、本実施形態では、陰極通水路２５および陽極通水路２６の通水方向での保持部材２４ｅの上流側端部および下流側端部の隔膜２３に接続された部分であって規定部２４ｆの周辺に位置して陰極通水路２５および陽極通水路２６の路面を構成する部分（以後、通水路確保部ともいう）２４ｍにおける隔膜２３の厚さ方向での厚さｔ１が、隔膜２３の厚さｔ２以下となっている。詳細には、保持部材２４ｅの連結部２４ｉの厚さが隔膜２３の厚さｔ２以下となっており、この連結部２４ｉにおける規定部２４ｆ間の部分が通水路確保部２４ｍとなっている。別の言い方をすると、陰極板２１および陽極板２２との対向方向で、保持部材２４ｅにおいて陰極板２１および陽極板２２と重なる部分（陰極板２１と陽極板２２とが投影される部分）における隔膜２３の厚さ方向での厚さｔ１が、隔膜２３の厚さｔ２以下となっている。   And in this embodiment, it is the part connected to the diaphragm 23 of the upstream edge part and downstream edge part of the holding member 24e in the water flow direction of the cathode water flow path 25 and the anode water flow path 26, and the regulation part 24f The thickness t1 in the thickness direction of the diaphragm 23 at a portion (hereinafter also referred to as a water passage securing section) 24m that is located in the periphery and constitutes the road surfaces of the cathode water passage 25 and the anode water passage 26 is the thickness of the diaphragm 23. t2 or less. Specifically, the thickness of the connecting portion 24i of the holding member 24e is equal to or less than the thickness t2 of the diaphragm 23, and a portion between the defining portions 24f in the connecting portion 24i is a water passage securing portion 24m. In other words, the diaphragm in the portion of the holding member 24e that overlaps the cathode plate 21 and the anode plate 22 (the portion on which the cathode plate 21 and the anode plate 22 are projected) in the facing direction of the cathode plate 21 and the anode plate 22. The thickness t1 in the thickness direction of 23 is equal to or less than the thickness t2 of the diaphragm 23.

また、この電解槽５は、図１に示すように、入口１１、第一出口１２、第二出口１３および第三出口１４とを有している。入口１１は、第一流入口２４ａおよび第二流入口２４ｂに連通しており、第一出口１２は、第一流出口２４ｃに連通しており、第二出口１３は、第二流出口２４ｄに連通しており、第三出口１４は、陰極通水路２５に連通している。また、入口１１は、パイプ１０ｂを介して浄水部４に接続されている。第一出口１２は、パイプ１０ｃを介して吐水パイプ９に連通されている。第二出口１３は、排水口１２に連通されている。第三出口１４は、排水弁１５に連通している。また、入口１１は、排水弁１６にも連通している。   In addition, as shown in FIG. 1, the electrolytic cell 5 has an inlet 11, a first outlet 12, a second outlet 13, and a third outlet 14. The inlet 11 communicates with the first inlet 24a and the second inlet 24b, the first outlet 12 communicates with the first outlet 24c, and the second outlet 13 communicates with the second outlet 24d. The third outlet 14 communicates with the cathode water passage 25. Moreover, the inlet 11 is connected to the water purification part 4 via the pipe 10b. The first outlet 12 communicates with the water discharge pipe 9 through the pipe 10c. The second outlet 13 communicates with the drain port 12. The third outlet 14 communicates with the drain valve 15. The inlet 11 also communicates with the drain valve 16.

この電解槽５では、陰極板２１と陽極板２２との間に電圧が印加されると、入口１１から第一流入口２４ａおよび第二流入口２４ｂを介して陰極通水路２５および陽極通水路２６に流入した水が電気分解される。陰極通水路２５においては陰極板２１と水との界面でアルカリイオン水が生成され、陽極通水路２６においては陽極板２２と水との界面で酸性水が生成される。陰極通水路２５で生成されたアルカリイオン水は、第一流出口２４ｃから第一出口１２を介して吐水パイプ９に至り、陽極通水路２６で生成された酸性水は、第二出口１３を介して排水口１２へ至る。   In this electrolytic cell 5, when a voltage is applied between the cathode plate 21 and the anode plate 22, the inlet 11 passes through the first inlet 24 a and the second inlet 24 b to the cathode water passage 25 and the anode water passage 26. The incoming water is electrolyzed. In the cathode water passage 25, alkali ion water is generated at the interface between the cathode plate 21 and water, and in the anode water passage 26, acidic water is generated at the interface between the anode plate 22 and water. The alkaline ionized water generated in the cathode water passage 25 reaches the water discharge pipe 9 from the first outlet 24 c through the first outlet 12, and the acidic water generated in the anode water passage 26 passes through the second outlet 13. It reaches the drain 12.

ここで、電解槽５においては、例えば、陽極板２２および陰極板２１の厚さは０．５ｍｍ、隔膜２３の厚さｔ２は０．１ｍｍ、陰極板２１と陽極板２２との相互の対向面間距離は３．５ｍｍとなっており、隔膜２３は、陰極板２１と陽極板２２との中間に位置している。かかる構造では、陰極板２１と隔膜２３との相互の対向面間の距離および陽極板２２と隔膜２３との相互の対向面間の距離は、それぞれ１．７ｍｍとなっている。そして、本実施形態では、保持部材２４ｅにおける規定部２４ｆ間の部分、即ち通水路確保部２４ｍでは、その厚さｔ１が隔膜２３の厚さｔ２以下となっているので、通水路確保部２４ｍと各電極（陽極板２２、陽極板２２）との相互の対向面間の距離は、１．７ｍｍ以下となっている。   Here, in the electrolytic cell 5, for example, the thickness of the anode plate 22 and the cathode plate 21 is 0.5 mm, the thickness t2 of the diaphragm 23 is 0.1 mm, and the opposing surfaces of the cathode plate 21 and the anode plate 22. The distance between them is 3.5 mm, and the diaphragm 23 is located between the cathode plate 21 and the anode plate 22. In such a structure, the distance between the opposing surfaces of the cathode plate 21 and the diaphragm 23 and the distance between the opposing surfaces of the anode plate 22 and the diaphragm 23 are 1.7 mm, respectively. And in this embodiment, since the thickness t1 is below the thickness t2 of the diaphragm 23 in the part between the regulation parts 24f in the holding member 24e, ie, the water passage securing part 24m, the water passage securing part 24m and The distance between the opposing surfaces of each electrode (anode plate 22, anode plate 22) is 1.7 mm or less.

このような構成の電解水生成装置１では、排水弁１５，１６が閉じられた状態において原水管２から水が供給されたことを流量センサ６が検出すると、制御部が電解槽５の陰極板２１と陽極板２２との間に電圧を印加する。これにより、浄水部４を通過して浄化された水を電解槽５で電気分解して、水からアルカリイオン水と酸性水とを生成する。生成されたアルカリイオン水は、吐水パイプ９から吐出されるとともに、酸性水は排水口１２から排出される。   In the electrolyzed water generating apparatus 1 having such a configuration, when the flow sensor 6 detects that water has been supplied from the raw water pipe 2 in a state where the drain valves 15 and 16 are closed, the control unit detects the cathode plate of the electrolyzer 5. A voltage is applied between 21 and the anode plate 22. Thereby, the water purified by passing through the water purification unit 4 is electrolyzed in the electrolytic cell 5 to generate alkali ion water and acidic water from the water. The generated alkaline ionized water is discharged from the water discharge pipe 9 and the acidic water is discharged from the drain port 12.

また、電解水生成装置１は、原水管２が閉じられて水の供給が止まったことを流量センサ６によって検出すると、陰極板２１と陽極板２２との極性を反転し、これら電極間に一定時間電圧を印加して逆電洗浄を行なう。一定時間の逆電洗浄が完了すると、排水弁１５，１６を開いて電解槽５内の水を排水弁１５，１６から排水する。   Also, when the flow rate sensor 6 detects that the raw water pipe 2 is closed and the supply of water is stopped, the electrolyzed water generating device 1 reverses the polarities of the cathode plate 21 and the anode plate 22 and keeps constant between these electrodes. Reverse voltage cleaning is performed by applying a time voltage. When the reverse electric cleaning for a certain time is completed, the drain valves 15 and 16 are opened to drain the water in the electrolytic cell 5 from the drain valves 15 and 16.

ここで、図６は、ｐＨと水中の溶解物との関係を示すグラフ、図７は、ｐＨと水中の炭酸カルシウムの溶解度との関係を示すグラフである。図６に示すように、水道水や井戸水、河川水などには、炭酸ガス（Ｈ２ＣＯ３）、炭酸水素イオン（ＨＣＯ３ −）、炭酸イオン（ＣＯ３ ２−）などの炭酸成分が溶解している。この炭酸成分は、式（１）に示すように、Ｈ＋を放出したり取り込んだりすることにより、ｐＨによってその形態が変化する。
Ｈ２ＣＯ３→Ｈ＋＋ＨＣＯ３ −→２Ｈ＋＋ＣＯ３ ２−・・・（１） Here, FIG. 6 is a graph showing the relationship between pH and dissolved matter in water, and FIG. 7 is a graph showing the relationship between pH and solubility of calcium carbonate in water. As shown in FIG. 6, carbonate components such as carbon dioxide (H 2 CO 3 ), hydrogen carbonate ions (HCO 3 − ), and carbonate ions (CO 3 2− ) are dissolved in tap water, well water, river water, and the like. is doing. As shown in the formula (1), the form of this carbonic acid component changes depending on pH by releasing or incorporating H + .
H 2 CO 3 → H + + HCO 3 − → 2H + + CO 3 2− (1)

水から電解生成されたアルカリイオン水（陰極水）の炭酸成分は、その形態としてＣＯ３ ２−を取る。ところで、水にはＣａ２＋やＭｇ２＋などのイオン成分が溶解しているが、Ｃａ２＋は、図７から分かるように、アルカリ性の高い水ほど溶解度が下がるため、水のアルカリ性が高くなるにつれＣａＣＯ３として水から析出する量が増大する。また、Ｍｇ２＋に関しては、ＭｇＣＯ３の水への溶解度がＣａＣＯ３と比較して低くないため、ＭｇＣＯ３としての析出量は比較的少ない。しかしながら、Ｍｇ（ＯＨ）２の水への溶解度が低いため、アルカリ性の条件下では、Ｍｇ（ＯＨ）２が水から析出することになる。 The carbonic acid component of alkaline ionized water (cathode water) generated electrolytically from water takes CO 3 2− as its form. By the way, although ion components, such as Ca <2+> and Mg < 2+> , are melt | dissolving in water, since the solubility of Ca <2+ > becomes so high that alkaline water is high as FIG. 7 shows, as the alkalinity of water becomes high, it is CaCO. 3 , the amount deposited from water increases. In addition, regarding Mg 2+ , the solubility of MgCO 3 in water is not lower than that of CaCO 3 , so that the amount of precipitation as MgCO 3 is relatively small. However, since Mg (OH) 2 has low solubility in water, Mg (OH) 2 is precipitated from water under alkaline conditions.

これらの析出成分は、電解槽５においては、陰極通水路２５の路面および陽極通水路２６の路面に固着してそれらの流路を徐々に閉塞する。したがって、それらの陰極通水路２５および陽極通水路２６は、その断面積が大きい方が良い。   In the electrolytic cell 5, these deposited components adhere to the road surface of the cathode water passage 25 and the road surface of the anode water passage 26, and gradually close the flow paths. Accordingly, the cathode water passage 25 and the anode water passage 26 should have a larger cross-sectional area.

これに対して、本実施形態では、上述したように、陰極通水路２５および陽極通水路２６の通水方向での保持部材２４ｅの上下流側の両端部の隔膜２３に接続された部分であって陰極通水路２５および陽極通水路２６の路面を構成する部分（通水路確保部）２４ｍにおける隔膜２３の厚さ方向での厚さｔ１が、隔膜２３の厚さｔ２以下である。したがって、通水路確保部２４ｍの厚さｔ１が隔膜２３の厚さｔ２よりも厚い場合に比べて、陰極通水路２５および陽極通水路２６の断面積を広くとることができるので、その分、水からの析出成分の固着による陰極通水路２５および陽極通水路２６の閉塞を抑制することができ、ひいては電解水生成装置１の長寿命化を図ることができる。   On the other hand, in the present embodiment, as described above, it is a portion connected to the diaphragm 23 at both end portions on the upstream and downstream sides of the holding member 24e in the water flow direction of the cathode water passage 25 and the anode water passage 26. The thickness t1 in the thickness direction of the diaphragm 23 in the portion (water passage securing portion) 24m constituting the road surface of the cathode water passage 25 and the anode water passage 26 is equal to or less than the thickness t2 of the diaphragm 23. Therefore, compared with the case where the thickness t1 of the water passage securing portion 24m is thicker than the thickness t2 of the diaphragm 23, the cross-sectional areas of the cathode water passage 25 and the anode water passage 26 can be increased. Clogging of the cathode water passage 25 and the anode water passage 26 due to the adhesion of the deposited components from the water can be suppressed, so that the life of the electrolyzed water generator 1 can be extended.

なお、本実施形態では、保持部材２４ｅの連結部２４ｉにおいて、厚さを隔膜２３の厚さｔ２以下にする部分を規定部２４ｆ材の間としたが、これに限ることなく、保持部材２４ｅにおける規定部２４ｆ材の間以外の部分の厚さも隔膜２３の厚さｔ２以下として良い。   In the present embodiment, in the connecting portion 24i of the holding member 24e, the portion whose thickness is equal to or less than the thickness t2 of the diaphragm 23 is between the defining portion 24f material. The thickness of the portion other than between the defining portion 24f may be equal to or less than the thickness t2 of the diaphragm 23.

FIG. 11 is a cross-sectional view taken along line GG in FIG. 11B, and FIG. 11 is a view showing the holding member, where FIG. 11A is a front view and FIG.

本実施形態は、基本的には第１実施形態と同じあるが、電解槽５のケーシング２４における保持部材２４ｅＡの形状が第１実施形態に対して異なる。   The present embodiment is basically the same as the first embodiment, but the shape of the holding member 24eA in the casing 24 of the electrolytic cell 5 is different from the first embodiment.

本実施形態では、第１実施形態と同じく、陰極通水路２５および陽極通水路２６の通水方向での保持部材２４ｅＡにおける上流側および下流側の端部には、相互に間隔をあけて配置された２つの規定部２４ｆが設けられている。そして、保持部材２４ｅＡの上流側おおよび下流側の端部である一対の連結部２４ｉＡにおける２つの規定部２４ｆ間には、凹部２４ｎが形成されており、凹部２４ｎに隔膜２３の一部が配置されている。具体的には、本実施形態では、連結部２４ｉＡに隔膜２３の端部が埋設されており、凹部２４ｎに位置する隔膜２３が連結部２４ｉＡから露出するようになっている。このような埋設は、例えば連結部２４ｉＡに隔膜２３をインサート成形したり、連結部２４ｉＡを２部品に分割してそれらの部品で隔膜２３の端部を挟むことによって実現できる。ここで、規定部２４ｆは第１実施形態と同様に、連結部２４ｉＡとは別部品として成形して連結部２４ｉＡに固着させてもよいし、連結部２４ｉＡに一体成形しても良い。図面では、規定部２４ｆが、連結部２４ｉＡとは別部品として成形されて連結部２４ｉＡに固着された例が示されている。   In the present embodiment, as in the first embodiment, the upstream end portion and the downstream end portion of the holding member 24eA in the water passage direction of the cathode water passage 25 and the anode water passage 26 are disposed with a space therebetween. Two defining portions 24f are provided. A recess 24n is formed between the two defining portions 24f of the pair of connecting portions 24iA that are upstream and downstream ends of the holding member 24eA, and a part of the diaphragm 23 is disposed in the recess 24n. Has been. Specifically, in this embodiment, the end of the diaphragm 23 is embedded in the connecting portion 24iA, and the diaphragm 23 located in the recess 24n is exposed from the connecting portion 24iA. Such embedding can be realized, for example, by insert-molding the diaphragm 23 in the connecting part 24iA, or by dividing the connecting part 24iA into two parts and sandwiching the end part of the diaphragm 23 with these parts. Here, similarly to the first embodiment, the defining portion 24f may be formed as a separate part from the connecting portion 24iA and fixed to the connecting portion 24iA, or may be integrally formed with the connecting portion 24iA. In the drawing, an example is shown in which the defining portion 24f is formed as a separate component from the connecting portion 24iA and is fixed to the connecting portion 24iA.

以上説明したように、本実施形態では、保持部材２４ｅＡの下流側の端部における２つの規定部２４ｆ間には、隔膜２３の一部が配置された凹部２４ｎが形成されており、凹部２４ｎ内に位置する隔膜２３が陰極通水路２５の路面および陽極通水路２６の路面を構成していることによって、保持部材２４ｅＡに凹部２４ｎが形成されていない場合に比べて、保持部材２４ｅＡの下流側の端部における２つの規定部２４ｆ間での陰極通水路２５および陽極通水路２６の断面積を広くとることができるので、その分、水からの析出成分の固着による通水路の閉塞を抑制することができ、ひいては電解水生成装置１の長寿命化を図ることができる。   As described above, in this embodiment, the recess 24n in which a part of the diaphragm 23 is disposed is formed between the two defining portions 24f at the downstream end of the holding member 24eA. Since the diaphragm 23 located at the side constitutes the road surface of the cathode water passage 25 and the road surface of the anode water passage 26, the downstream side of the holding member 24eA is compared to the case where the concave portion 24n is not formed in the holding member 24eA. Since the cross-sectional areas of the cathode water passage 25 and the anode water passage 26 can be widened between the two defining portions 24f at the end, the blockage of the water passage due to the adhesion of the precipitated components from water is suppressed accordingly. As a result, the life of the electrolyzed water generator 1 can be extended.
