Further, in the third In the figure and Fig. 4, the pressing plate 24g is omitted. Further, one of the connecting portions 24i and one end portion of the cathode plate 21 and the two defining portions 24f' supporting one end portion of the cathode plate 21 form a cathode water passage. The first inflow port 24a of the path 25; the first outflow port 24c of the cathode water passage 25 is formed by the other connecting portion 24i and the other end of the cathode plate 21 and the two defining portions 24f supporting the other end portion of the cathode plate 21 .

In other words, in the opposing direction of the cathode 21 and the anode plate 22, the thickness of the separator 23 in the portion where the cathode plate 21 and the anode plate 22 overlap in the holding member 24e (the portion projected by the cathode plate 21 and the anode 22) The thickness in the direction is equal to or less than the thickness t2 of the separator 23. Further, in the electrolytic cell 5, as shown in Fig. 1, there are: 11, a first outlet 12, a second outlet 13, and a third outlet 14. 1 1 is connected to the first inflow port 24a and The second inflow port 24b; the first port 12 is connected to the first outflow port 24c; the second outlet 13 is connected to the second outflow port 2; and the third outlet 14 is connected to the cathode through water port 25. Further, the inlet 1 1, is connected to the water purification unit 4 via the tube 1 Ob. The outlet 12 is connected to the spout pipe 9 via the tube 10c. The second out | is connected to the drain 1 7 . The third exit 1 4 is connected to the drain 丨. Further, the inlet 11 is also connected to the drain valve 16. In the electrolytic cell 5, when a voltage is applied between the cathode plate 21 and the anode 22, the inlet 11 flows into the cathode water passage 25 and the anode water passage 26 through the first inlet 24a and the second port 24b. electrolysis. The cathode plate 21 in the cathode water passage 25 forms alkaline water with water, and acidic water is formed at the interface of the anode plate 22 in the anode water passage 26. The alkali generated by the cathode water passage 25 is 24m t2 in degrees "4f plate and plate degree t1 inlet inlet-out communication path first 3 13 Μ 1 5 plate water inlet and water separation-13 - 201034978 Zishui' arrives at the spout pipe 9 from the first-class outlet 2 4 c via the first outlet 12, and the acidic water generated in the anode water passage 26 reaches the drain through the second outlet 13 . Here, in the electrolytic cell 5, for example, the thickness of the anode plate 22 and the cathode plate 21 is 〇5 mm, the thickness t2 of the separator 23 is 0.1 mm, and the distance between the opposing faces of the cathode plate 21 and the anode plate 22 is opposite. It is 3.5 mm; the separator 23 is located between the cathode plate 21 and the anode plate 22. In such a configuration, the distance between the opposing faces of the cathode plate 21 and the separator 23 and the distance between the opposing faces of the anode plate 22 and the separator 23 are respectively 1. 7 mm. Further, in the present embodiment, the portion between the restricting portions 24f of the holding member 24e, that is, the water passage ensuring portion 24m, is such that the thickness t1 is equal to or less than the thickness t2 of the diaphragm 23, The distance between the water passage ensuring portion 24m and the surfaces of the respective electrodes (the anode plate 22 and the anode plate 22) is 1.7 mm or more. In the electrolyzed water generating apparatus 1 having such a configuration, when the flow rate detector 6 detects that water is supplied from the raw water pipe 2 in a state where the drain valves 15 and 16 are closed, the control unit applies a voltage to the electrolytic cell 5 Between the cathode plate 2 1 and the anode plate 2 2 . Thereby, the water purified by the purified water unit 4 is electrolyzed in the electrolytic cell 5, and alkaline ionized water and acidic water are generated from the water. The alkaline ionized water generated is discharged from the spout pipe 9, and the acidic water is discharged from the drain port 17. Further, when the flow rate detector 6 detects that the raw water pipe 2 is closed and the supply of water is stopped, the polarity of the cathode plate 21 and the anode plate 22 are reversed, and the electrodes are applied between the electrodes. The voltage of a certain time comes to -14 - 201034978 for reverse voltage cleaning. When the reverse voltage cleaning is completed for a certain period of time, the drain valve 15 and 16 are opened to drain the water in the electrolytic cell 5 from the drain valves 15 and 16 , and Fig. 6 shows the pH and the water. A graph of the relationship of dissolved matter. Figure 7 is a graph showing the relationship between pH and solubility of carbonic acid in water. As shown in Fig. 6, in tap water, well water, river water, etc., carbonic acid components such as carbon dioxide gas (h2co3), hydrogencarbonate ion (hco3_), and cesium carbonate ion (C032·) are dissolved. The carbonic acid component, as shown in the formula (1), is released or taken in by H+, and the form is changed according to pH. H2C034 H++ HC03-4 2H++ C032. (1) Alkaline ionized water (cathode) produced by water electrolysis The carbonic acid component of water) is morphologically removed from C032-. Further, although ionic components such as Ca2+ or OMg2+ are dissolved in water, Ca2+, as can be seen from Fig. 7, since the solubility in water which is higher in alkali is lower, the alkalinity with water is higher. The amount of precipitation from water in the form of CaC03 will increase. Further, in Mg2+, since the solubility of MgC03 in water is not lower than that of CaC03, the amount of precipitation in the form of MgC03 is relatively small. However, since Mg(OH)2 has a low solubility in water, M g (Ο Η) 2 precipitates from water under alkaline conditions. These deposition components are fixed to the path surface of the cathode water passage 25 and the path surface of the anode water passage 26 in the electrolytic cell 5, and the -15-201034978 flow path is gradually closed. Therefore, the cathode water passage path 25 and the anode water passage path 26 have a larger sectional area. On the other hand, in the present embodiment, as described above, the portion of the cathode water-passing path 25 and the anode water-passing path 26 that are connected to the diaphragm 23 at the both downstream portions on the upstream side of the holding member 24e is also connected. The portion (water passage ensuring portion) 24m constituting the path surface of the cathode water passing path 25 and the anode water passing path 26, and the thickness t1 in the thickness direction of the diaphragm 23 located in the portion 24m is the thickness of the diaphragm 23. Below t2. Therefore, when the thickness t1 of the water passage ensuring portion 24m is thicker than the thickness t2 of the diaphragm 23, the sectional area of the cathode water passage 25 and the anode water passage 26 can be enlarged, thereby expanding In part, it is possible to suppress the clogging of the cathode water passage 25 and the anode water passage 26 due to the fixed adhesion of the components precipitated from the water, so that the life of the electrolyzed water generator 1 can be extended. In the present embodiment, the connecting portion 24i of the holding member 24e is provided between the limiting portion 24f with a thickness equal to or less than the thickness t2 of the diaphragm 23. However, the present invention is not limited thereto, and may be located in the holding member. The thickness of the portion other than the portion between the portions 24f of the 24e is set to be equal to or less than the thickness t2 of the separator 23.
