1 to 3 show a schematic configuration of an electrolyzed water producing apparatus 1 of this embodiment. The electrolyzed water producing apparatus 1 is widely applied to the production of the dialysate-preparing water described above, as well as the production of drinking electrolyzed water.

As shown in FIG. 1, the electrolyzed water producing apparatus 1 includes a main body frame 2, an electrolyzer 4, a water inlet pipe 6, and a water outlet pipe 7. The body frame 2 supports the electrolytic bath 4, the water inlet pipe 6 and the water outlet pipe 7.

As shown in FIG. 3, the electrolytic cell 4 has an anode chamber 41, a cathode chamber 42, and a diaphragm 43. The electrolytic cell 4 has, for example, the same configuration as that disclosed in JP-A-2016-159237. That is, a power feeding body is arranged in each of the anode chamber 41 and the cathode chamber 42 of the electrolytic cell 4, and the diaphragm 43 is made of, for example, a solid polymer electrolyte membrane made of a fluorine-based resin material having a sulfonic acid group. The rectangular shape is long in the vertical direction. The anode chamber 41 and the cathode chamber 42 are separated by a diaphragm 43. The water inlet pipe 6 supplies water to the electrolytic cell 4. The water outlet pipe 7 takes out the water electrolyzed in the electrolytic cell 4.

The second water inlet pipe 62 as described above is capable of flowing a large amount of water by increasing the inner diameter, that is, the cross-sectional area of the flow channel while ensuring pressure resistance performance as compared with the first water inlet pipe 61. On the other hand, the first water inlet pipe 61 can reduce the components constituting the pipe (for example, the joint 61z connecting the pipes in a separable manner, the nut 61y joined to the joint 61z, etc.), and can reduce the size of the electrolyzed water generating apparatus 1. To contribute.

The first water inlet pipe 61 and the second water inlet pipe 62 are arranged so that their positions are offset from each other with respect to the electrolytic cell 4 in order to prevent mutual interference. In the present invention, the first water inlet pipe 61 having a small number of components is arranged closer to the electrolytic cell 4 than the second water inlet pipe 62.

In FIG. 3, a two-dot chain line indicates a contour of the electrolyzed water generation device 1Z in which the second water inlet pipe 62 having a large component is arranged closer to the electrolytic cell 4 than the first water inlet pipe 61. As is clear from FIG. 3, in the electrolyzed water producing apparatus 1 of the present invention, the first water inlet pipe 61 and the second water inlet pipe 62 may be arranged in the vicinity of the electrolyzer 4 as compared with the electrolyzed water producing apparatus 1Z.

The first water inlet pipe 61 is connected to the anode chamber 41. In the anode chamber 41, oxygen is generated by electrolysis, and electrolyzed oxygen water that is melted is generated. The electrolyzed oxygen water generated in the anode chamber 41 is not suitable for dialysate preparation and drinking, and is therefore normally discarded. Therefore, by limiting the water flowing into the anode chamber 41 from the first water inlet pipe 61, it is possible to effectively use the water. The first water inlet pipe 61 of the present embodiment has a smaller outer diameter than the second water inlet pipe 62 and is suitable for effective use of such water.

On the other hand, the second water inlet pipe 62 has a second upstream portion 62a and a second downstream portion 62b. The second upstream portion 62a is supported by the body frame 2. The second downstream portion 62b is connected to the cathode chamber 42.

The second downstream portion 62b has a tube 62c extending in the direction D1. This makes it possible to arrange a plurality of electrolytic cells 4 along the direction D1 and connect the cathode chambers 42 to each other via the tube 62c, and to generate a large amount of electrolytic hydrogen water. As shown in FIG. 3, the tube 61c connected to the small component is arranged closer to the electrolytic cell 4 in the in-plane direction of the diaphragm 43 than the tube 62c, and the tube 61c and the tube 62c are close to the electrolytic cell 4.

The fourth upstream portion 72a has a tube 72c extending in the direction D1. As a result, a plurality of electrolytic cells 4 are arranged along the direction D1, and the cathode chambers 42 thereof can be connected to each other via the tube 72c, and a large amount of electrolytic hydrogen water can be generated. As shown in FIG. 3, a tube 71c connected to a small component is disposed closer to the electrolytic cell 4 in the in-plane direction of the diaphragm 43 than the tube 72c, and the tube 71c and the tube 72c are disposed near the electrolytic cell 4.
