　本発明は、水を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。 The present invention relates to an electrolyzed water generating apparatus that electrolyzes water to generate electrolyzed water.
　従来、隔膜で仕切られた電解室を有する電解槽を備え、電解室に供給される水道水等を電気分解して水素が溶け込んだ電解水素水を生成する電解水生成装置が知られている。例えば、特許文献１には、溶存水素濃度を高めるために、直列に接続された２つの電解槽を備えた電解水生成装置が開示されている。 2. Description of the Related Art Conventionally, an electrolyzed water generating apparatus that includes an electrolyzer having an electrolysis chamber partitioned by a diaphragm and generates electrolyzed hydrogen water in which hydrogen is dissolved by electrolyzing tap water supplied to the electrolysis chamber is known. For example, Patent Document 1 discloses an electrolyzed water generating device including two electrolyzers connected in series in order to increase the dissolved hydrogen concentration.
　上記電解水生成装置は、陰極と陽極とを対向配置した第１の電解部と、第１の電解部の陰極側で生成したアルカリ性水の溶存水素濃度を高める第２の電解部を備える。このため、飲用に適したｐＨ値で溶存水素濃度の高い電解水が容易に生成される。 The electrolyzed water generating apparatus includes a first electrolyzing unit in which a cathode and an anode are arranged to face each other, and a second electrolyzing unit that increases the concentration of dissolved hydrogen in alkaline water generated on the cathode side of the first electrolyzing unit.

特許第４４１７７０７号公報Japanese Patent No. 4417707
　しかしながら、特許文献１に記載された電解水生成装置では、第１の電解部の陰極室では、水の電気分解に伴い、カルシウム等のスケールが析出する。そして、第１の電解部の陰極室で析出したスケールは、第１の電解部での陰極室下流側の水路に付着し、円滑な水流を阻害する。すなわち、第２の電解部の陰極室のみならず第１の電解部の陰極室と第２の電解部の陰極とを連通させる水路にもスケールが付着し、上記アルカリ性水の円滑な流れが阻害されるおそれがある。 However, in the electrolyzed water generating device described in Patent Document 1, in the cathode chamber of the first electrolysis unit, scales such as calcium are deposited with the electrolysis of water. Then, the scale deposited in the cathode chamber of the first electrolysis unit adheres to the water channel downstream of the cathode chamber in the first electrolysis unit and inhibits smooth water flow. That is, not only the cathode chamber of the second electrolysis unit but also the water channel connecting the cathode chamber of the first electrolysis unit and the cathode of the second electrolysis unit adheres to the smooth flow of the alkaline water. There is a risk of being.
　本発明は、以上のような実状に鑑み案出されたもので、スケールの付着を抑制しつつ、飲用に適したｐＨ値で溶存水素濃度の高い電解水を生成することが可能な電解水生成装置を提供することを主たる目的としている。 The present invention has been devised in view of the actual situation as described above, and generates electrolyzed water that can generate electrolyzed water having a high dissolved hydrogen concentration at a pH value suitable for drinking while suppressing the adhesion of scales.

　本発明は、水を電気分解するための電解室を複数備えた電解水生成装置であって、各電解室には、互いに対向して配置された第１給電体及び第２給電体と、前記電解室を前記第１給電体側の第１極室と、前記第２給電体側の第２極室とに区分する隔膜とが配され、各電解室は、各第１極室を直列又は並列に連通させる第１水路と、各第２極室を直列に連通させる第２水路とによって接続され、前記第２水路の上流側にある前記第２極室では、中性の電解水が生成され、前記第２水路の下流側にある前記第２極室では、アルカリ性の電解水が生成されることを特徴とすることを特徴とする。 The present invention is an electrolyzed water generating apparatus including a plurality of electrolysis chambers for electrolyzing water, and each electrolysis chamber includes a first power supply body and a second power supply body disposed to face each other, and A diaphragm that divides the electrolysis chamber into a first electrode chamber on the first power feeder side and a second electrode chamber on the second power feeder side is arranged, and each electrolysis chamber has each first electrode chamber in series or in parallel The first water channel to be communicated and the second water channel to communicate each second electrode chamber in series, in the second electrode chamber on the upstream side of the second water channel, neutral electrolyzed water is generated, In the second electrode chamber on the downstream side of the second water channel, alkaline electrolyzed water is generated.
　本発明に係る前記電解水生成装置において、前記各第２極室内での水流の方向は、同一であることが望ましい。 In the electrolyzed water generating apparatus according to the present invention, it is desirable that the direction of water flow in each second electrode chamber is the same.
　本発明に係る前記電解水生成装置において、各電解室は、前記水流の方向に垂直な方向に並設されていることが望ましい。 In the electrolyzed water generating apparatus according to the present invention, it is preferable that the electrolysis chambers are arranged in a direction perpendicular to the direction of the water flow.
　本発明に係る前記電解水生成装置において、前記第２水路の上流側にある電解室は、第１電解槽の第１側壁によって区画され、前記第２水路の少なくとも一部は、前記第１側壁の内部に形成されていることが望ましい。 In the electrolyzed water generating device according to the present invention, the electrolysis chamber on the upstream side of the second water channel is partitioned by the first side wall of the first electrolysis tank, and at least a part of the second water channel is formed by the first side wall. It is desirable that it is formed inside.
　本発明に係る前記電解水生成装置において、前記第１水路は、各第１極室を直列に連通させ、前記第１水路の少なくとも一部は、前記第１側壁の内部に形成されていることが望ましい。 In the electrolyzed water generating apparatus according to the present invention, the first water channel communicates each first electrode chamber in series, and at least a part of the first water channel is formed inside the first side wall. Is desirable.
　本発明に係る前記電解水生成装置において、前記第２水路の下流側にある電解室は、第２電解槽の第２側壁によって区画され、前記第２水路の少なくとも一部は、前記第２側壁の内部に形成されていることが望ましい。 In the electrolyzed water generating device according to the present invention, the electrolysis chamber on the downstream side of the second water channel is partitioned by the second side wall of the second electrolysis tank, and at least a part of the second water channel is formed by the second side wall. It is desirable that it is formed inside.
　本発明に係る前記電解水生成装置において、前記第１水路は、各第１極室を直列に連通させ、前記第１水路の少なくとも一部は、前記第２側壁の内部に形成されていることが望ましい。 In the electrolyzed water generating device according to the present invention, the first water channel communicates each first electrode chamber in series, and at least a part of the first water channel is formed inside the second side wall.

　本発明に係る前記電解水生成装置において、前記第２水路の上流側にある前記電解室に配される前記隔膜は、固体高分子膜であることが望ましい。 In the electrolyzed water generating device according to the present invention, it is preferable that the diaphragm disposed in the electrolysis chamber on the upstream side of the second water channel is a solid polymer film.
　本発明の電解水生成装置は、水を電気分解するための電解室を複数備え、第２水路の上流側にある第２極室では、中性の電解水が生成される。この上流側の第２極室ではスケールの析出が生じないため、上流側の第２極室及び第２水路では、スケールの付着が抑制される。なお、上流側の第２極室では、水の電気分解によって発生した水素ガスが溶け込んだ中性の電解水が生成される。 The electrolyzed water generating apparatus of the present invention includes a plurality of electrolyzing chambers for electrolyzing water, and neutral electrolyzed water is generated in the second electrode chamber on the upstream side of the second water channel. In the upstream second pole chamber, no scale deposition occurs, and therefore, the scale adhesion is suppressed in the upstream second pole chamber and the second water channel.

　一方、第２水路の下流側にある第２極室では、水の電気分解によって溶存水素濃度が高められると共に、還元されたアルカリ性の電解水が生成される。これに伴い、下流側の第２極室では、スケールが析出するものの、このスケールが付着する領域は、下流側の第２極室よりもさらに下流側の水路に限定され、その対策も容易となる。これにより、スケールの付着を抑制しつつ、飲用に適したｐＨ値で溶存水素濃度の高い電解水を生成することが可能となる。 On the other hand, in the second electrode chamber on the downstream side of the second water channel, the dissolved hydrogen concentration is increased by electrolysis of water, and reduced alkaline electrolyzed water is generated. Along with this, although the scale is deposited in the second polar chamber on the downstream side, the area where the scale adheres is limited to the water channel further downstream than the second polar chamber on the downstream side, and the countermeasures are easy. Become. Thereby, it is possible to generate electrolyzed water having a high dissolved hydrogen concentration at a pH value suitable for drinking while suppressing adhesion of scale.

　以下、本発明の実施の一形態が図面に基づき説明される。
　図１は、本発明の実施形態である電解水生成装置１の流路の概略構成を示している。電解水生成装置１は、例えば、家庭の飲用水の生成に用いられる。 Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows a schematic configuration of a flow path of an electrolyzed water generating apparatus 1 according to an embodiment of the present invention. The electrolyzed water generating apparatus 1 is used, for example, for generating domestic drinking water.
　電解水生成装置１は、電解槽３、４、…を複数備える。図１では、一対の電解槽３、４を備えた電解水生成装置１が示されている。電解水生成装置１は、３以上の電解槽３、４、…を備えていてもよい。 The electrolyzed water generating apparatus 1 includes a plurality of electrolytic cells 3, 4,. In FIG. 1, an electrolyzed water generating apparatus 1 including a pair of electrolytic cells 3 and 4 is shown. The electrolyzed water generating apparatus 1 may include three or more electrolytic cells 3, 4,.
　電解槽３及び４は、直列に接続されている。電解槽３は、電解槽４に対して上流側に設けられている。 The electrolytic cells 3 and 4 are connected in series. The electrolytic cell 3 is provided on the upstream side with respect to the electrolytic cell 4.
　電解槽３は、水を電気分解するための電解室３０と、電解室３０内で互いに対向して配置された第１給電体３１及び第２給電体３２と、電解室３０を第１給電体３１側の第１極室３０Ａと、第２給電体３２側の第２極室３０Ｂとに区分する隔膜３３とを有する。 The electrolytic cell 3 includes an electrolysis chamber 30 for electrolyzing water, a first power feeding body 31 and a second power feeding body 32 arranged to face each other in the electrolysis chamber 30, and the electrolysis chamber 30 as a first power feeding body. The diaphragm 33 is divided into a first pole chamber 30A on the 31 side and a second pole chamber 30B on the second power feeder 32 side.
　第１給電体３１及び第２給電体３２の一方は陽極給電体として適用され、他方は陰極給電体として適用される。電解室３０の第１極室３０Ａ及び第２極室３０Ｂの両方に水が供給され、第１給電体３１及び第２給電体３２に直流電圧が印加されることにより、電解室３０内で水の電気分解が生ずる。 One of the first power supply 31 and the second power supply 32 is applied as an anode power supply, and the other is applied as a cathode power supply. Water is supplied to both the first electrode chamber 30 </ b> A and the second electrode chamber 30 </ b> B of the electrolysis chamber 30, and a direct-current voltage is applied to the first power supply body 31 and the second power supply body 32, thereby causing water in the electrolysis chamber 30. Electrolysis occurs.
　上流側の電解室３０の隔膜３３には、例えば、スルホン酸基を有するフッ素系樹脂からなる固体高分子膜が用いられている。隔膜３３の両面には、白金からなるめっき層が形成されている。一方、第１給電体３１及び第２給電体３２には、例えば、チタニウム等からなるエクスパンドメタル等の網状金属の表面に白金のめっき層が形成されたものが適用されている。このような網状の第１給電体３１及び第２給電体３２は、隔膜３３を挟持しながら、隔膜３３の表面に水を行き渡らせることができ、電解室３０内での電気分解を促進する。 For example, a solid polymer film made of a fluorine-based resin having a sulfonic acid group is used for the diaphragm 33 of the upstream electrolysis chamber 30. A plating layer made of platinum is formed on both surfaces of the diaphragm 33. On the other hand, for example, a material in which a platinum plating layer is formed on the surface of a net-like metal such as an expanded metal made of titanium or the like is applied to the first power supply 31 and the second power supply 32. Such a net-like first power supply body 31 and second power supply body 32 can distribute water to the surface of the diaphragm 33 while sandwiching the diaphragm 33, and promote electrolysis in the electrolytic chamber 30.
　隔膜３３のめっき層と第１給電体３１及び第２給電体３２とは、当接し、電気的に接続される。隔膜３３は、電気分解で生じたイオンを通過させる。隔膜３３を介して第１給電体３１と第２給電体３２とが電気的に接続される。固体高分子材料からなる隔膜３３が適用される電解室３０では、電解水素水のｐＨ値が上昇することなく、すなわち電解室３０内の水が中性に維持されつつ、電気分解が進行する。 The plating layer of the diaphragm 33 is in contact with and electrically connected to the first power feeder 31 and the second power feeder 32. The diaphragm 33 allows ions generated by electrolysis to pass through. The first power feeder 31 and the second power feeder 32 are electrically connected through the diaphragm 33. In the electrolysis chamber 30 to which the diaphragm 33 made of a solid polymer material is applied, electrolysis proceeds without increasing the pH value of the electrolyzed hydrogen water, that is, while the water in the electrolysis chamber 30 is maintained neutral.
　電解室３０内で水が電気分解されることにより、水素ガス及び酸素ガスが発生する。例えば、第１給電体３１が陽極給電体として適用される場合、第１極室３０Ａでは、酸素ガスが発生し、酸素ガスが溶け込んだ中性の電解酸素水が生成される。一方、第２極室３０Ｂでは、水素ガスが発生し、水素ガスが溶け込んだ中性の電解水素水が生成される。第１給電体３１が陰極給電体として適用される場合、第１極室３０Ａでは、水素ガスが発生し、水素ガスが溶け込んだ中性の電解水素水が生成される。一方、第２極室３０Ｂでは、酸素ガスが発生し、酸素ガスが溶け込んだ中性の電解酸素水が生成される。 Electrolysis of water in the electrolysis chamber 30 generates hydrogen gas and oxygen gas. For example, when the 1st electric power feeder 31 is applied as an anode electric power feeder, in the 1st pole chamber 30A, oxygen gas will generate | occur | produce and the neutral electrolyzed oxygen water which oxygen gas melt | dissolved will be produced | generated. On the other hand, in the second electrode chamber 30B, hydrogen gas is generated, and neutral electrolytic hydrogen water in which the hydrogen gas is dissolved is generated. When the first power supply 31 is applied as a cathode power supply, hydrogen gas is generated in the first electrode chamber 30A, and neutral electrolytic hydrogen water in which the hydrogen gas is dissolved is generated. On the other hand, in the second electrode chamber 30B, oxygen gas is generated, and neutral electrolytic oxygen water in which the oxygen gas is dissolved is generated.
　電解槽４は、水を電気分解するための電解室４０内に、互いに対向して配置された第１給電体４１及び第２給電体４２と、電解室４０を第１給電体４１側の第１極室４０Ａと、第２給電体４２側の第２極室４０Ｂとに区分する隔膜４３とを有する。 The electrolytic cell 4 includes a first power feeding body 41 and a second power feeding body 42 that are disposed to face each other in an electrolysis chamber 40 for electrolyzing water, and the electrolysis chamber 40 on the first power feeding body 41 side. The diaphragm 43 is divided into a first pole chamber 40A and a second pole chamber 40B on the second power feeding body 42 side.
　第１給電体４１及び第２給電体４２の一方は陽極給電体として適用され、他方は陰極給電体として適用される。電解室４０の第１極室４０Ａ及び第２極室４０Ｂの両方に水が供給され、第１給電体４１及び第２給電体４２に直流電圧が印加されることにより、電解室４０内で水の電気分解が生ずる。 One of the first power supply 41 and the second power supply 42 is applied as an anode power supply, and the other is applied as a cathode power supply. Water is supplied to both the first electrode chamber 40 </ b> A and the second electrode chamber 40 </ b> B of the electrolysis chamber 40, and a direct current voltage is applied to the first power supply body 41 and the second power supply body 42. Electrolysis occurs.
　隔膜４３は、例えば、ポリテトラフルオロエチレン（ＰＴＦＥ）親水膜によって構成されている。隔膜４３を挟んで対向配置される第１給電体４１及び第２給電体４２には、例えば、チタニウム等の金属板が適用される。第１給電体４１及び第２給電体４２は、隔膜４３から離隔する位置に配されている。 The diaphragm 43 is made of, for example, a polytetrafluoroethylene (PTFE) hydrophilic film. For example, a metal plate such as titanium is applied to the first power feeding body 41 and the second power feeding body 42 that are arranged to face each other with the diaphragm 43 interposed therebetween. The first power feeding body 41 and the second power feeding body 42 are arranged at positions separated from the diaphragm 43.
　上記構成の電解槽４では、電解水素水のｐＨ値が上昇しながら、すなわち陰極室内の水のアルカリ強度が高まりつつ、電気分解が信号する。 In the electrolytic cell 4 having the above configuration, electrolysis signals while the pH value of the electrolytic hydrogen water increases, that is, the alkaline strength of the water in the cathode chamber increases.
　第１給電体４１が陽極給電体として適用される場合、第１極室４０Ａでは、酸素ガスが発生し、酸素ガスが溶け込んだ酸性の電解酸素水が生成される。一方、第２極室４０Ｂでは、水素ガスが発生し、水素ガスが溶け込んだアルカリ性の電解水素水が生成される。第１給電体４１が陰極給電体として適用される場合、第１極室４０Ａでは、水素ガスが発生し、水素ガスが溶け込んだアルカリ性の電解水素水が生成される。一方、第２極室４０Ｂでは、酸素ガスが発生し、酸素ガスが溶け込んだ酸性の電解酸素水が生成される。 When the first power supply body 41 is applied as an anode power supply body, oxygen gas is generated in the first electrode chamber 40A, and acidic electrolytic oxygen water in which the oxygen gas is dissolved is generated. On the other hand, in the second electrode chamber 40B, hydrogen gas is generated, and alkaline electrolytic hydrogen water in which the hydrogen gas is dissolved is generated. When the first power supply body 41 is applied as a cathode power supply body, in the first electrode chamber 40A, hydrogen gas is generated, and alkaline electrolytic hydrogen water in which the hydrogen gas is dissolved is generated. On the other hand, in the second electrode chamber 40B, oxygen gas is generated, and acidic electrolytic oxygen water in which the oxygen gas is dissolved is generated.
　電解水生成装置１は、電解室３０及び４０に電気分解される水を供給するための給水路２０と、電解室３０及び４０から電解水を吐出するための吐水路６１及び６２とを有している。 The electrolyzed water generating apparatus 1 has a water supply channel 20 for supplying water to be electrolyzed to the electrolysis chambers 30 and 40, and water discharge channels 61 and 62 for discharging electrolyzed water from the electrolysis chambers 30 and 40. ing.
　電解水生成装置１には、給水路２０から原水が供給される。原水には、一般的には水道水が利用されるが、その他、例えば、井戸水、地下水等を用いることができる。電解水生成装置１が飲用の電解水素水の生成に用いられる場合等では、原水を浄化する浄水カートリッジ等が給水路２０に適宜設けられる。 Raw water is supplied from the water supply channel 20 to the electrolyzed water generator 1. As the raw water, tap water is generally used, but well water, ground water, and the like can be used. In the case where the electrolyzed water generating device 1 is used for generating potable electrolytic hydrogen water, a water purification cartridge or the like for purifying raw water is appropriately provided in the water supply channel 20.
　給水路２０は、給水路２１及び給水路２２に分岐する。給水路２１は、第１極室３０Ａの下段部に接続されている。給水路２２は、第２極室３０Ｂの下端部に接続されている。給水路２０に流入した水は、給水路２１及び２２を通過して、第１極室３０Ａ、第２極室３０Ｂに流れ込む。 The water supply channel 20 branches into a water supply channel 21 and a water supply channel 22. The water supply path 21 is connected to the lower part of the first pole chamber 30A. The water supply path 22 is connected to the lower end of the second electrode chamber 30B. The water flowing into the water supply channel 20 passes through the water supply channels 21 and 22 and flows into the first electrode chamber 30A and the second electrode chamber 30B.
　吐水路６１は、第１極室４０Ａの上端部に接続されている。図２及び４に示される電解槽４では、吐水路６１は、電解槽４の第２側壁４Ｗに形成されている水路５３を介して第１極室４０Ａと接続されている。これにより、第１極室４０Ａから流出した水は、吐水路６１に流れ込む。 The water discharge path 61 is connected to the upper end of the first pole chamber 40A. In the electrolytic cell 4 shown in FIGS. 2 and 4, the water discharge channel 61 is connected to the first electrode chamber 40 </ b> A via the water channel 53 formed in the second side wall 4 </ b> W of the electrolytic cell 4. Thereby, the water that has flowed out of the first pole chamber 40 </ b> A flows into the water discharge path 61.

In the electrolytic cell 4 shown in FIGS. 3 and 5, the water discharge channel 62 is connected to the second electrode chamber 40 </ b> B through the water channel 54 formed in the second side wall 4 </ b> W of the electrolytic cell 4. Thereby, the water that has flowed out of the second electrode chamber 40 </ b> B flows into the water discharge channel 62.
　給電体３１、３２及び給電体４１、４２に供給される電解電流は、制御部（図示せず）によって制御される。制御部は、給電体３１、３２及び給電体４１、４２等の各部の制御を司る。制御部は、例えば、各種の演算処理、情報処理等を実行するＣＰＵ（Central Processing Unit）及びＣＰＵの動作を司るプログラム及び各種の情報を記憶するメモリ等を有している。 The electrolytic current supplied to the power feeding bodies 31 and 32 and the power feeding bodies 41 and 42 is controlled by a control unit (not shown). The control unit controls each unit such as the power feeding bodies 31 and 32 and the power feeding bodies 41 and 42. The control unit includes, for example, a CPU (Central Processing Unit) that executes various arithmetic processes and information processing, a program that controls the operation of the CPU, a memory that stores various information, and the like.
　制御部は、例えば、第１給電体３１、４１及び第２給電体３２、４２の極性を制御する。 A control part controls the polarity of the 1st electric power feeders 31 and 41 and the 2nd electric power feeders 32 and 42, for example.
　第１給電体３１、４１及び第２給電体３２、４２の極性を相互に変更することにより、電解水素水又は電解酸素水のうち所望の電解水が吐水路６１から吐水され、不要な電解水が吐水路６２から排出されうる。また、第１給電体３１、４１及び第２給電体３２、４２が陽極給電体又は陰極給電体として機能する時間を均一化して、電解室３０及び電解室４０でのスケールの付着を抑制できる。 By changing the polarities of the first power feeding bodies 31 and 41 and the second power feeding bodies 32 and 42 to each other, desired electrolyzed water out of the electrolyzed hydrogen water or the electrolyzed oxygen water is discharged from the water discharge path 61, and unnecessary electrolyzed water Can be discharged from the water discharge channel 62. In addition, the time during which the first power feeding bodies 31 and 41 and the second power feeding bodies 32 and 42 function as an anode power feeding body or a cathode power feeding body can be made uniform, and scale adhesion in the electrolysis chamber 30 and the electrolysis chamber 40 can be suppressed.
　以下、特に断りのない限り、第１給電体３１、４１が陽極給電体として適用される場合について説明するが、第１給電体３１、４１が陰極給電体として適用される場合についても同様である。 Hereinafter, the case where the first power feeders 31 and 41 are applied as anode power feeders will be described unless otherwise specified, but the same applies to the case where the first power feeders 31 and 41 are applied as cathode power feeders. .
　制御部は、例えば、予め設定された溶存水素濃度に応じて、電解電流が所望の値となるように、給電体３１、３２及び給電体４１、４２に印加する直流電圧をフィードバック制御する。例えば、電解電流が過大である場合、制御部は、上記電圧を減少させ、電解電流が過小である場合、制御部は、上記電圧を増加させる。これにより、給電体３１、３２及び給電体４１、４２に供給する電解電流が適切に制御される。 The control unit performs feedback control of the DC voltage applied to the power feeding bodies 31 and 32 and the power feeding bodies 41 and 42 so that the electrolysis current becomes a desired value according to, for example, a preset dissolved hydrogen concentration. For example, when the electrolysis current is excessive, the control unit decreases the voltage, and when the electrolysis current is excessive, the control unit increases the voltage. Thereby, the electrolysis current supplied to the power feeding bodies 31 and 32 and the power feeding bodies 41 and 42 is appropriately controlled.
　電解室３０の第１極室３０Ａと電解室４０の第１極室４０Ａとは、第１水路５１によって直列に連通されている。また、電解室３０の第２極室３０Ｂと電解室４０の第２極室４０Ｂとは、第２水路５２によって直列に連通されている。このように、中性の電解水を生成する第２極室３０Ｂとアルカリ性の電解水を生成する第２極室４０Ｂとが、第２水路５２によって直列に連通されているので、溶存水素濃度を高めるために電解電流を増加させる場合であっても、電解水のｐＨ値が過度に上昇することが抑制される。これにより、飲用に適したｐＨ値で溶存水素濃度の高い電解水を生成することが可能となる。 The first electrode chamber 30 </ b> A of the electrolysis chamber 30 and the first electrode chamber 40 </ b> A of the electrolysis chamber 40 are connected in series by a first water channel 51. The second electrode chamber 30 </ b> B of the electrolysis chamber 30 and the second electrode chamber 40 </ b> B of the electrolysis chamber 40 are connected in series by the second water channel 52. Thus, since the 2nd polar chamber 30B which produces | generates neutral electrolyzed water, and the 2nd polar chamber 40B which produces | generates alkaline electrolyzed water are connected in series by the 2nd water channel 52, dissolved hydrogen concentration is set. Even when the electrolysis current is increased to increase the pH value, the pH value of the electrolyzed water is prevented from excessively rising. Thereby, it is possible to generate electrolyzed water having a high dissolved hydrogen concentration at a pH value suitable for drinking.
　なお、第１給電体３１及び４１が陽極給電体として適用される場合、すなわち、第１極室３０Ａ及び４０Ａが陽極室として適用される場合、第１極室３０Ａと第１極室４０Ａとが、第１水路５１によって並列に連通されるように構成されていてもよい。この場合、第１極室３０Ａで生成された酸素ガスが第１極室４０Ａに流入することがないので、第１給電体４１の表面にも水が十分に供給される。従って、電解室４０で効率よく電気分解が行なわれ、溶存水素濃度を高めることが可能となる。 In addition, when the 1st electric power feeding bodies 31 and 41 are applied as an anode electric power feeding body, ie, when 1st pole chamber 30A and 40A are applied as an anode chamber, 1st pole chamber 30A and 1st pole chamber 40A become. The first water channel 51 may be connected in parallel. In this case, oxygen gas generated in the first electrode chamber 30A does not flow into the first electrode chamber 40A, so that water is sufficiently supplied also to the surface of the first power feeder 41. Therefore, electrolysis is efficiently performed in the electrolysis chamber 40, and the dissolved hydrogen concentration can be increased.
　電解室３０は、第２水路５２の上流側に配され、電解室４０は、第２水路５２の下流側に配されている。すなわち、中性の電解水を生成する第２極室３０Ｂは、第２水路５２の上流側に配され、アルカリ性の電解水を生成する第２極室４０Ｂは、第２水路５２の下流側に配されている。これにより、上流側にある第２極室３０Ｂではスケールの析出が生じないため、第２極室３０Ｂ及び第２水路５２では、スケールの付着が抑制される。なお、上流側の第２極室では、水の電気分解によって発生した水素ガスが溶け込んだ中性の電解水が生成される。 The electrolysis chamber 30 is disposed on the upstream side of the second water channel 52, and the electrolysis chamber 40 is disposed on the downstream side of the second water channel 52. That is, the second polar chamber 30B that generates neutral electrolyzed water is arranged on the upstream side of the second water channel 52, and the second polar chamber 40B that generates alkaline electrolyzed water is on the downstream side of the second water channel 52. It is arranged. Thereby, since deposition of scale does not occur in the second polar chamber 30B on the upstream side, scale adhesion is suppressed in the second polar chamber 30B and the second water channel 52. In the second electrode chamber on the upstream side, neutral electrolyzed water in which hydrogen gas generated by water electrolysis is dissolved is generated.
　一方、第２水路５２の下流側にある第２極室４０Ｂでは、水の電気分解によって溶存水素濃度が高められると共に、還元されたアルカリ性の電解水が生成される。これに伴い、下流側の第２極室では、電気分解に伴いスケールが析出するものの、このスケールが付着する領域は、第２極室４０Ｂよりもさらに下流側の水路に限定され、その対策も容易となる。例えば、第２極室４０Ｂよりもさらに下流側の水路の断面積を大きく設定する等により、スケール対策が容易に行える。従って、スケールの付着を抑制しつつ、飲用に適したｐＨ値で溶存水素濃度の高い「電解水素水」を生成することが可能となる。 On the other hand, in the second polar chamber 40B on the downstream side of the second water channel 52, the dissolved hydrogen concentration is increased by electrolysis of water, and reduced alkaline electrolyzed water is generated. Along with this, in the second polar chamber on the downstream side, the scale is deposited as a result of electrolysis, but the area where the scale adheres is limited to the water channel further downstream than the second polar chamber 40B. It becomes easy. For example, scale measures can be easily taken by setting the cross-sectional area of the water channel further downstream from the second pole chamber 40B. Therefore, it is possible to generate “electrolytic hydrogen water” having a high dissolved hydrogen concentration at a pH value suitable for drinking while suppressing adhesion of scale.
　各第１極室３０Ａ、４０Ａ内での水流の方向は、矢印３０Ｘ、４０Ｘで示されるように、同一である。本実施形態では、第１極室３０Ａ、４０Ａ内での水流の方向３０Ｘ、４０Ｘは、第１極室３０Ａ、４０Ａの下端部から上端部に向く鉛直方向である。このため、第１極室３０Ａ、４０Ａでの水流の方向３０Ｘ、４０Ｘと第１極室３０Ａ、４０Ａで生成される酸素ガスの移動する方向が一致するため、酸素ガスが効率よく第１極室３０Ａ、４０Ａから排出される。これにより、第１極室３０Ａ、４０Ａで発生する酸素ガスが第１給電体３１及び４１の表面に滞留することが抑制される。従って、第１給電体３１及び４１の表面にも水が十分に供給され、電解室３０及び４０で効率よく電気分解が行なわれ、溶存水素濃度を高めることが可能となる。 The direction of water flow in the first electrode chambers 30A and 40A is the same as indicated by arrows 30X and 40X. In the present embodiment, the water flow directions 30X and 40X in the first polar chambers 30A and 40A are vertical directions from the lower end portions to the upper end portions of the first polar chambers 30A and 40A. For this reason, the directions 30X and 40X of the water flow in the first electrode chambers 30A and 40A coincide with the moving direction of the oxygen gas generated in the first electrode chambers 30A and 40A, so that the oxygen gas is efficiently contained in the first electrode chamber 30A and 40A. It is discharged from 30A and 40A. Thereby, it is suppressed that the oxygen gas generated in the first electrode chambers 30 </ b> A and 40 </ b> A stays on the surfaces of the first power feeding bodies 31 and 41. Accordingly, water is sufficiently supplied also to the surfaces of the first power feeding bodies 31 and 41, and electrolysis is efficiently performed in the electrolysis chambers 30 and 40, so that the dissolved hydrogen concentration can be increased.
　各第２極室３０Ｂ、４０Ｂ内での水流の方向は、矢印３０Ｙ、４０Ｙで示されるように、同一である。本実施形態では、第２極室３０Ｂ、４０Ｂ内での水流の方向３０Ｙ、４０Ｙは、第２極室３０Ｂ、４０Ｂの下端部から上端部に向く鉛直方向である。このため、第２極室３０Ｂ及び４０Ｂでの水流の方向３０Ｙ、４０Ｙと第２極室３０Ｂ及び４０Ｂで生成される水素ガスの移動する方向が一致するため、水素ガスが効率よく第２極室３０Ｂ及び４０Ｂから排出される。これにより、第２極室３０Ｂ及び４０Ｂで発生する水素ガスが第２給電体３２及び４２の表面に滞留することが抑制される。従って、第２給電体３２及び４２の表面にも水が十分に供給され、電解室３０及び４０で効率よく電気分解が行なわれ、溶存水素濃度を高めることが可能となる。 The direction of the water flow in the second electrode chambers 30B and 40B is the same as indicated by arrows 30Y and 40Y. In the present embodiment, the directions 30Y and 40Y of the water flow in the second polar chambers 30B and 40B are vertical directions from the lower end portions to the upper end portions of the second polar chambers 30B and 40B. For this reason, since the directions 30Y and 40Y of the water flow in the second polar chambers 30B and 40B coincide with the moving direction of the hydrogen gas generated in the second polar chambers 30B and 40B, the hydrogen gas efficiently flows into the second polar chamber. It is discharged from 30B and 40B. Thereby, the hydrogen gas generated in the second electrode chambers 30B and 40B is suppressed from staying on the surfaces of the second power feeding bodies 32 and 42. Therefore, water is sufficiently supplied also to the surfaces of the second power feeders 32 and 42, and electrolysis is efficiently performed in the electrolysis chambers 30 and 40, so that the dissolved hydrogen concentration can be increased.
　電解室３０、４０は、水流の方向３０Ｘ、４０Ｘ、３０Ｙ、４０Ｙに垂直な方向に並設されているのが望ましい。このような形態では、電解水生成装置１の高さを抑制し低背化を図ることが容易となる。 It is desirable that the electrolysis chambers 30 and 40 are juxtaposed in a direction perpendicular to the water flow directions 30X, 40X, 30Y and 40Y. In such a form, it becomes easy to reduce the height by suppressing the height of the electrolyzed water generating apparatus 1.

That is, at least a part of the first water channel 51 is formed inside the first side wall 3W. Thereby, the structure of the electrolyzed water production | generation apparatus 1 is simplified, and it becomes possible to aim at a cost reduction.

The water channel 51b is configured by, for example, a rubber tube or the like, and is disposed outside the electrolytic cells 3 and 4.

　図１に示されるように、本実施形態では、給水路２１及び２２の経路中には、流量調整弁２３が設けられているのが望ましい。流量調整弁２３は、給水路２１及び２２を流れる水の量を調整する。流量調整弁２３によって第１極室３０Ａ及び第２極室３０Ｂに流れ込む水の量が調整される。 As shown in FIG. 1, in this embodiment, it is desirable that a flow rate adjusting valve 23 is provided in the water supply passages 21 and 22. The flow rate adjusting valve 23 adjusts the amount of water flowing through the water supply channels 21 and 22. The amount of water flowing into the first electrode chamber 30A and the second electrode chamber 30B is adjusted by the flow rate adjusting valve 23.
　本実施形態では、第１極室４０Ａ及び第２極室４０Ｂと吐水路６１及び６２との間には、流路切替弁６３が設けられているのが望ましい。流路切替弁６３は、第１極室４０Ａ及び第２極室４０Ｂと吐水路６１及び６２との接続を選択的に切り替える。 In this embodiment, it is desirable that a flow path switching valve 63 is provided between the first and second electrode chambers 40A and 40B and the water discharge channels 61 and 62. The flow path switching valve 63 selectively switches the connection between the first polar chamber 40A and the second polar chamber 40B and the water discharge paths 61 and 62.
　第１給電体３１、４１及び第２給電体３２、４２の極性の切り替えと流路切替弁６３による流路の切り替えとを同期させることにより、ユーザーによって選択された電解水（図１では電解水素水）が常に一方の吐水路（例えば、吐水路６２）から吐出されうる。 By synchronizing the polarity switching of the first power feeding bodies 31 and 41 and the second power feeding bodies 32 and 42 and the switching of the flow path by the flow path switching valve 63, the electrolyzed water selected by the user (in FIG. Water) can always be discharged from one discharge channel (for example, the discharge channel 62).
　第１給電体３１、４１及び第２給電体３２、４２の極性の切り替えにあたっては、制御部が、流量調整弁２３と流路切替弁６３とを、連動して動作させる形態が望ましい。これにより、極性の切り替え前後において、吐水路６２に接続されている極室への水の供給量を十分に確保しつつ、吐水路６１に接続されている極室への水の供給量を抑制して、水の有効利用を図ることが可能となる。流量調整弁２３と流路切替弁６３とは、例えば、特許第５８０９２０８号公報に記載されているように、一体に形成され、単一のモーターによって連動して駆動される形態が望ましい。すなわち、流量調整弁２３及び流路切替弁６３は、円筒形状の外筒体と内筒体等によって構成される。内筒体の内側及び外側には、流量調整弁２３及び流路切替弁６３を構成する流路が形成され、各流路は、流量調整弁２３及び流路切替弁６３の動作状態に応じて適宜交差するように構成されている。このような弁装置は、「ダブルオートチェンジクロスライン弁」と称され、電解水生成装置１の構成及び制御の簡素化に寄与し、電解水生成装置１の商品価値をより一層高める。本電解水生成装置１にあっては、図２乃至５に示されるように、電解槽３の第１側壁３Ｗ及び電解槽４の第２側壁４Ｗに水路５３及び５４が設けられることにより、流量調整弁２３と流路切替弁６３とを電解槽３及び電解槽４の下方に隣接して配置することができ、電解水生成装置１の構成がより一層簡素化されうる。 In the switching of the polarities of the first power supply bodies 31 and 41 and the second power supply bodies 32 and 42, it is desirable that the control unit operates the flow rate adjusting valve 23 and the flow path switching valve 63 in conjunction with each other. Thereby, before and after switching the polarity, the amount of water supplied to the polar chamber connected to the water discharge passage 61 is sufficiently suppressed while the amount of water supplied to the polar chamber connected to the water discharge passage 62 is sufficiently secured. Thus, it is possible to make effective use of water. For example, as described in Japanese Patent No. 5809208, the flow rate adjusting valve 23 and the flow path switching valve 63 are preferably integrally formed and driven in conjunction with a single motor. That is, the flow rate adjusting valve 23 and the flow path switching valve 63 are configured by a cylindrical outer cylinder, an inner cylinder, and the like. The flow path constituting the flow rate adjustment valve 23 and the flow path switching valve 63 is formed inside and outside the inner cylinder, and each flow path is in accordance with the operating state of the flow rate adjustment valve 23 and the flow path switching valve 63. It is configured to cross appropriately. Such a valve device is referred to as a “double auto change cross line valve”, contributes to the simplification of the configuration and control of the electrolyzed water generating device 1, and further increases the commercial value of the electrolyzed water generating device 1. In the present electrolyzed water generating apparatus 1, as shown in FIGS. 2 to 5, the water channels 53 and 54 are provided in the first side wall 3 </ b> W of the electrolyzer 3 and the second side wall 4 </ b> W of the electrolyzer 4. The adjustment valve 23 and the flow path switching valve 63 can be disposed adjacent to the lower part of the electrolytic cell 3 and the electrolytic cell 4, and the configuration of the electrolyzed water generating device 1 can be further simplified.
　図６は、電解水生成装置１の変形例である電解水生成装置１Ａを示している。電解水生成装置１Ａでは、電解室３０及び４０が水流の方向３０Ｘ、４０Ｘ、３０Ｙ、４０Ｙすなわち鉛直方向に並べて配されている点で、電解水生成装置１とは異なる。電解水生成装置１Ａのうち、以下で説明されていない構成に関しては、電解水生成装置１と同様である。 FIG. 6 shows an electrolyzed water generating apparatus 1 </ b> A that is a modification of the electrolyzed water generating apparatus 1. The electrolyzed water generating apparatus 1A is different from the electrolyzed water generating apparatus 1 in that the electrolysis chambers 30 and 40 are arranged side by side in the water flow directions 30X, 40X, 30Y, and 40Y, that is, in the vertical direction. In the electrolyzed water generating apparatus 1A, configurations not described below are the same as those of the electrolyzed water generating apparatus 1.
