  The outer O-ring 30 and the inner O-ring 32 may be accommodated in the right side surface of the intermediate chamber case 34 in a double manner. Further, the outer O-ring 38 and the inner O-ring 40 may be accommodated in the left side surface of the intermediate chamber case 34 in a double manner.

  The cathode chamber unit 14 may include a plate-like cathode chamber case 56 made of resin. In the center of the right side surface of the cathode chamber case 56, a cathode chamber recess 56e serving as an inner wall of the cathode chamber 74 may be formed.

A plate-like cathode 52 may be disposed on the right side surface of the cathode chamber case 56 so as to cover the cathode chamber recess 56e and the O-ring 54.

  The cathode 52 may be formed with a tab-like terminal 52a so as to protrude forward. The cathode 52 may be formed with a large number of holes for passing a liquid in a mesh shape. These holes may be formed on the inner side of the position facing the inner O-ring 40. The material of the cathode 52 is preferably a metal having a lower ionization tendency than hydrogen atoms, and examples thereof include a platinum electrode and a diamond electrode.

  A cation exchange membrane 50, which is a flexible thin film, is disposed on the right side of the cathode 52 so as to follow the cathode 52, and a cathode chamber 74 is partitioned liquid-tightly by the cation exchange membrane 50 and the cathode chamber recess 56e. May be. Raw water described later may flow from the cathode chamber liquid supply port 72, and the raw water may become alkaline electrolyzed water in the cathode chamber 74 and be discharged from the cathode chamber drain port 76. In FIG. 5B, the flow path of the raw water flowing in from the cathode chamber supply port 72 and discharged from the cathode chamber drain port 76 is indicated by a two-dot chain line arrow A3.

  As described above, the raw water flows into one corner (for example, the lower corner on the near side) of the cathode chamber 74 and is discharged from the opposite corner (for example, the upper corner on the far side), so that the raw water is discharged. You may make it spread throughout. Further, the raw water may be divided into an upper flow and a lower flow by forming the convex portion 20f in the anode chamber concave portion 20e as described above.

  Further, a fastening member such as a screw may penetrate through a plurality of holes provided in the anode chamber case 20, the intermediate chamber case 34, and the cathode chamber case 56 along the X1-X2 direction. Then, the anode chamber unit 10, the intermediate chamber unit 12, and the cathode chamber unit 14 are tightened together by the tightening member, and the anode chamber unit 10, the intermediate chamber unit 12, and the cathode chamber unit 14 are mutually connected in the X1-X2 direction. It may be pressed.

  Alternatively, the anode 24 may be fixed by sandwiching the anode 24 between the outer O-ring 30 and the O-ring 22. The anode 24 may be supported by the convex portion 20f. Further, the anion exchange membrane 26 may be fixed by sandwiching the anion exchange membrane 26 between the inner O-ring 32 and the anode 24.

  Further, the cathode 52 may be fixed by sandwiching the cathode 52 between the outer O-ring 38 and the O-ring 54. Moreover, the cathode 52 may be supported by the convex part 56f. Further, the cation exchange membrane 50 may be fixed by sandwiching the cation exchange membrane 50 between the inner O-ring 40 and the cathode 52.

  In the three-tank electrolyzed water production apparatus 1, the anode chamber 62 and the intermediate chamber 68 are partitioned through the anion exchange membrane 26, and the intermediate chamber 68 and the cathode chamber 74 are partitioned through the cation exchange membrane 50. Also good. The anion exchange membrane 26 may allow anions to pass between the anode chamber 62 and the intermediate chamber 68, and the cation exchange membrane 50 may allow cations to pass between the intermediate chamber 68 and the cathode chamber 74. .

  In the three tank type electrolyzed water production apparatus 1, the anode 24 and the cathode 52 are connected to a direct current power source through wiring formed in the hole formed in the terminal 24 a of the anode 24 and the hole formed in the terminal 52 a of the cathode 52. (Not shown) may be electrically connected. Then, a voltage may be applied between the anode 24 and the cathode 52 to perform an electrolysis process in which raw water and a chlorinated electrolyte aqueous solution are targets for electrolysis.

  Examples of raw water supplied from the anode chamber supply port 60 to the anode chamber 62 and raw water supplied from the cathode chamber supply port 72 to the cathode chamber 74 include tap water, well water, ion exchange water, distilled water, or RO. Water or the like may be used. The raw water may be water having a total electrolyte concentration of 15 ppm or less. For example, the metal ion concentration (sodium ion concentration) in the raw water may be 2 ppm or less, for example.

  The chlorine electrolyte dissolved in the chlorine electrolyte aqueous solution supplied from the intermediate chamber liquid supply port 66 to the intermediate chamber 68 refers to an electrolyte that generates chloride ions when dissolved in water. As the chlorine electrolyte, for example, an alkali metal chloride (for example, sodium chloride or potassium chloride) or an alkaline earth metal (for example, calcium chloride or magnesium chloride) may be used.

  The concentration of the high-concentration chlorinated electrolyte aqueous solution supplied from the intermediate chamber liquid supply port 66 to the intermediate chamber 68 does not greatly affect the quality of the prepared electrolytic water, but is preferably as high as possible. . When the chlorine electrolyte contained in the chlorine electrolyte aqueous solution is sodium chloride, the concentration of sodium chloride contained in the chlorine electrolyte aqueous solution is preferably 26% by mass or less.

  The intermediate chamber liquid supply port 66 and the intermediate chamber drain port 70 may be connected to a pipe constituting the closed water channel. Then, the chlorine-based electrolyte aqueous solution may be circulated in the closed channel by a pump (not shown). In this case, the intermediate chamber 68 is a part of the closed water channel.

  In the above-described electrolysis process, the chlorine ions in the intermediate chamber 68 pass through the anion exchange membrane 26 and move to the anode chamber 62, and the chlorine ions are converted into chlorine at the anode 24, and acidic electrolysis is performed in the anode chamber 62. Water may be generated. On the other hand, cations in the intermediate chamber 68 may pass through the cation exchange membrane 50 and move to the cathode chamber 74, and alkaline electrolyzed water may be generated in the cathode chamber 74.

  When the above electrolysis process is performed, hydrogen bubbles are generated at the cathode 52. In addition, chlorine and oxygen bubbles may be generated at the anode 24. When such bubbles are attached to the electrodes such as the anode 24 and the cathode 52, unevenness of electrolysis reaction may occur between the portion where the bubbles are attached and the portion where the bubbles are not attached.

  Here, as shown in FIGS. 1 and 2, the anode chamber is such that the cross section perpendicular to the X1-X2 direction of the anode chamber recess 20e has a rounded rectangular shape inclined obliquely upward from the near side toward the far side. Case 20 may be formed. For example, the lower surface inclined obliquely upward toward the anode chamber drain port 64 is formed on the upper wall portion 20a in this manner, so that bubbles generated by electrolysis in the anode 24 can be smoothly discharged into the anode chamber drain port. 64 may be discharged.

  Similarly, the cathode chamber case 56 may be formed such that a cross section perpendicular to the X1-X2 direction of the cathode chamber recess 56e has a rounded rectangular shape inclined obliquely upward from the near side toward the far side. In this way, a lower surface that is inclined obliquely upward toward the cathode chamber drain port 76 is formed on the upper wall portion 56 a, so that bubbles generated by electrolysis at the cathode 52 are smoothly generated from the cathode chamber drain port 76. It may be allowed to be discharged.

  Here, for example, as described above, the opening 36 is formed in the intermediate chamber case 34, and most of the ions used for electrolysis at the anode 24 and the cathode 52 are supplied from the aqueous chlorine electrolyte solution present in the opening 36. Let's say that In this case, the electrolysis reaction at the anode 24 is mainly performed in a region on the anode 24 that overlaps with the opening 36 when viewed along the X1-X2 direction. The electrolysis reaction at the cathode 52 is mainly performed in a region on the cathode 52 that overlaps the opening 36 when viewed along the X1-X2 direction.

  Therefore, for example, as shown in FIGS. 1, 2, 5 </ b> A, and 5 </ b> B, the top surface of the opening 36 is assumed to be lower than the top surface of the anode chamber 62 and the top surface of the cathode chamber 74. That is, the lower surface located below the lower surface of the upper wall portion 20a that partitions the anode chamber 62 and the lower surface of the upper wall portion 56a that partitions the cathode chamber 74 is formed on the upper wall portion 34a that partitions the intermediate chamber 68. And In this way, since the bubbles generated in the anode 24 move upward, most of the bubbles staying in the anode chamber 62 are spaces in the anode chamber 62 above the plane in which the lower surface of the upper wall portion 34a is expanded. 5A and 5B, the anode chamber marginal space 62a is present. Further, most of the bubbles generated in the cathode 52 and staying in the cathode chamber 74 are illustrated in FIGS. 5A and 5B, which are spaces in the cathode chamber 74 above the plane obtained by expanding the lower surface of the upper wall portion 34a. It exists in the cathode chamber marginal space 74a.

  As described above, the lower wall positioned below the lower surface of the upper wall portion 20a that partitions the anode chamber 62 is formed on the upper wall portion 34a that partitions the intermediate chamber 68. The unevenness of the decomposition reaction may be suppressed. In addition, the lower surface positioned below the lower surface of the upper wall part 56a defining the cathode chamber 74 is formed on the upper wall part 34a defining the intermediate chamber 68, thereby suppressing unevenness of electrolysis reaction in the cathode 52. You may be made to do.

  Further, it is considered that the lower surface of the space formed by the entire bubbles staying in the anode chamber 62 is almost horizontal. Therefore, as shown in FIGS. 1 and 2, the lower surface of the space formed by the entire staying bubbles and the lower surface of the anode chamber allowance space 62a are substantially aligned with the upper wall portion 34a defining the intermediate chamber 68. A lower surface may be formed. In this way, it is possible to suppress the bubbles staying in the anode chamber 62 from protruding from the anode chamber marginal space 62a even though the anode chamber marginal space 62a remains. Similarly, as described above, it is possible to suppress the bubbles remaining in the cathode chamber 74 from protruding from the cathode chamber margin space 74a even though the cathode chamber margin space 74a remains.

  As shown in FIGS. 1 and 2, an upper surface parallel to the lower surface of the upper wall portion 20a is formed on the lower wall portion 20b, and the inner side surface of the front side wall portion 20c (the front side wall portion 20c of the front side wall portion 20c) is formed on the rear side wall portion 20d.
