  However, in the electrolyzed water generating apparatus disclosed in Patent Literature 1 and Patent Literature 2, raw water flows in order from the electrolyzer on the side close to the upstream end of the water supply channel, so the electrolyzer on the side close to the upstream end of the water supply channel And the far-side electrolyzer has different raw water incoming pressure at the water supply port of the electrolyzer, that is, there is a difference in the incoming amount of raw water into each electrolyzer.

  Here, the pH value of the electrolytic hydrogen water and the value of the dissolved hydrogen concentration are values determined according to the current applied to the electrode of the electrolytic cell and the amount of raw water entering the electrolytic cell (the amount of flowing water in the electrolytic cell). It is. Therefore, even if the same current is applied to the electrodes of each electrolytic cell, if the amount of raw water entering each electrolytic cell is different, the value of the pH of the electrolytic hydrogen water discharged from each electrolytic cell will also be different. . Then, there is a possibility that the electrolytic hydrogen water having the characteristics desired by the user (pH value or dissolved hydrogen concentration value) cannot be taken. The water generated by the electrolyzed water generator is often taken directly into the human body as drinking water or cooking water, and it is preferable that the characteristics (pH value and dissolved hydrogen concentration value) of the electrolyzed hydrogen water differ from the desired characteristics.

That is, the length from the upstream end of the branch water supply channel to each electrolytic cell is equal to each other. Thereby, the dispersion | variation in the incoming water pressure in each electrolytic vessel inlet can be reduced more effectively.

It is characterized by comprising a branch waterway connected to the side waterway and a second waterway connected to the downstream end of the branch waterway.

  According to this aspect, the first and second drainage channels are connected by the branched drainage channel branched into two or more. As a result, the electrolytic hydrogen water or acidic water discharged from the electrolytic cell is branched into two or more at the branch outlet through the upstream outlet and the downstream outlet, and then through the second outlet. Water is discharged outside the electrolyzed water generator. By setting it as such a drainage channel structure, the dispersion | variation in the drainage pressure in each electrolytic vessel exit can be reduced. Since the outlets of the electrolytic cells communicate with the inlets of the electrolytic cells, the variation in the incoming water pressure can be reduced by reducing the variation in the outgoing water pressure. That is, it is possible to more effectively reduce the variation in the incoming water pressure at each electrolytic cell inlet.

[Other Embodiments]
Although the present invention has been described with the preferred embodiments, various modifications can be made.

  For example, in the embodiment, an example in which three electrolytic cells 21a, 21b, and 21c are provided has been described. However, the present invention can be applied to four or more electrolytic cells. FIG. 7 shows an example in which the electrolyzed water generating apparatus 10 includes four electrolytic cells.

  In Fig.7 (a), the four 1st-4th electrolytic cells 21a-21d are arranged side by side, and the 1st-4th electrolytic cells 21a-21d and the upstream water supply path 65 are 1st-1st, respectively. The fourth downstream water supply channels 66a to 66d are connected. The second water supply path 61a and the upstream water supply path 65 are connected by a branch water supply path 64 (first to third branch water supply paths 64a to 64c) branched into three. Specifically, the downstream end of the first branch water supply path 64a is a first upstream water supply path that connects the upstream end of the first downstream water supply path 66a and the upstream end of the second downstream water supply path 66b. It is connected to the center of 65a. Similarly, the downstream end of the second branch water supply path 64b is connected to the upstream end of the second downstream water supply path 66b and the upstream end of the third downstream water supply path 66c. Connected to the center. The downstream end of the third branch water supply channel 64c is the center of the third upstream water supply channel 65c that connects the upstream end of the third downstream water supply channel 66c and the upstream end of the fourth downstream water supply channel 66d. It is connected to the. Thereby, the dispersion | variation in the incoming water pressure in each electrolytic cell (1st-4th electrolytic cell 21a-21d) entrance can be reduced.

  In addition, in the structure of Fig.7 (a), you may omit any one of the 1st-3rd branch water supply paths 64a-64c. However, each electrolytic cell (first to fourth electrolytic cells 21a to 21d) is more effectively provided with the branched water supply channel 64 (first to third branched water channels 64a to 64c) branched into three. Variations in incoming water pressure at the inlet can be reduced.

  In the configuration of FIG. 7A, the downstream end of the second water supply path 61a and the branch water supply path 64 are connected to the downstream end of the second water supply path 61a and the third branch water supply path 64c. The configuration is as described above, but is not limited thereto. For example, in Fig.7 (a), you may comprise so that the downstream end part of the 2nd water supply path 61a and the downstream end part of the 2nd branch water supply path 64b may become coaxial.

  Moreover, the connection position of the branch water supply path 64 and the upstream water supply path 65 is not limited to Fig.7 (a). For example, in FIG. 7A, the second branch water supply path 64b and the second downstream water supply path 66b or the third downstream water supply path 66c may be configured to be coaxial.

  Moreover, in the structure of Fig.7 (a), between the downstream end part of the 2nd water supply path 61a and the upstream end part of the branch water supply path 64, as shown in FIG.7 (b), 4th and 5th You may further branch into two by the branch water supply path 64d and 64e. By adopting such a configuration, the lengths from the upstream end of the branch water supply path 64 to the upstream ends of the first to fourth downstream water supply paths 66a to 66d are equal to each other. Thereby, the dispersion | variation in the inlet pressure in each electrolytic cell (1st-4th electrolytic cell 21a-21d) inlet_port | entrance can be reduced more effectively.

  Moreover, as shown to Fig.8 (a), (b), you may make it the structure which branches the intake channel 62 into two or more. FIG. 8A shows an example when there are three electrolytic cells, and FIG. 8B shows an example when there are four electrolytic cells. In Fig.8 (a), between each intake tank 62b, 62b, 62b and the main intake path 62a of each electrolytic cell (1st-3rd electrolytic cell 21a-21c), each electrolytic cell (1st-3rd). The branch outlet 91 (first and second) branching into two or more between the downstream outlet 90 connected to the connecting intakes 62b, 62b, 62b of the electrolytic cells 21a-21c) and the main intake 62a. Branch water outlets 91a, 91b) are provided. Specifically, the upstream end of the first branch outlet 91 a is connected to the downstream end of the connection intake 62 b connected to the first electrolytic tank 21 a and the connection intake 62 b connected to the second electrolytic tank 21 b. It is connected to the center of the first downstream water outlet 90a connecting the downstream end. Similarly, the upstream end of the second branch outlet 91b is connected to the downstream end of the connection intake 62b connected to the second electrolytic tank 21b and the downstream end of the connection intake 62b connected to the third electrolytic tank 21c. It is connected to the center of the second downstream water outlet 90b that connects the parts. By setting it as such a structure, the dispersion | variation in the water discharge pressure in each electrolytic vessel water intake outlet can be reduced. Since the outlets of the electrolytic cells communicate with the inlets of the electrolytic cells, the variation in the incoming water pressure can be reduced by reducing the variation in the outgoing water pressure. As shown in FIG. 8B, even when the number of the fourth electrolytic cell 21d increases, the downstream end of the connection intake passage 62b connected to the third electrolytic cell 21c and the connection connected to the fourth electrolytic cell 21d. By providing a third downstream outlet channel 90c that connects the downstream end of the intake channel 62b and a third branch outlet channel 91c that is connected to the center of the third downstream outlet channel 90c, FIG. The same effect can be obtained. It should be noted that the same effect can be obtained even if the drainage channel configuration of FIGS. 8A and 8B is applied to the drainage channel 63.

  In the embodiment, the double cross line valve 50 and the ratio adjustment unit 61e are provided between each electrolytic cell 21 and the upstream water supply path 65. For example, the electrolytic cell 21 and the upstream water supply path 65 may be directly connected by a flexible pipe or a metal pipe without the 61e.

  In the embodiment, the example in which each electrolytic cell 21 includes two water supply pipes 24 and 24 and two water discharge pipes 25 and 25 has been described. However, one water supply pipe and one water discharge pipe may be provided. .
