Here, “extends in the second horizontal direction H2” means that the component extends in the second horizontal direction H2, and not only extends in parallel to the second horizontal direction H2, but also in the second horizontal direction H2. It includes a form that extends while tilting.

  Similarly, as shown in FIGS. 1 to 3, the water outlet 7 has a water outlet 70 disposed on the second horizontal direction H2 side with respect to the post-treatment device 300 and the electrolyzed water generator 1. The water outlet 70 extends from the second side portion 26 of the electrolyzed water generating device 1 in the second horizontal direction H2 to the outside of the main body frame 2 and is connected to the post-processing device 300 on the back side of the manufacturing device 100.

  The front side of the manufacturing apparatus 100 is simplified by the water inlet channel 60 and the water outlet channel 70. Further, the space generated on the back side of the electrolyzed water generating device 1 with the piping configuration of the water inlet channel 6 and the water outlet channel 7 can be used as a space for pulling out the second electrolysis unit 41B and performing maintenance.

  FIG. 10 shows the configuration of the water intake path 6 inside the electrolyzed water generating apparatus 1. The water intake channel 6 includes main water intake channels 61, 61a, and 61b and secondary water intake channels 62a and 62b having a smaller diameter than the main water intake channels 61, 61a, and 61b.

The main water inlet 61 is connected to the pretreatment device 200 outside the main body frame 2. The main water intake channels 61 a and 61 b are branched from the main water intake channel 61.

  One end of the secondary water passage 62a branches from the main water passage 61a, and the other end is connected to the cathode chamber of each electrolytic cell 43 (see FIGS. 4 to 6). The water that has passed through the pretreatment device 200 flows into the cathode chamber of each electrolytic cell 43 through the main water intake channels 61 and 61a and the secondary water supply channel 62a sequentially. One end of the secondary water passage 62 b branches off from the main water passage 61 b, and the other end is connected to the anode chamber of each electrolytic cell 43. The water that has passed through the pretreatment device 200 also flows into the anode chamber of each electrolytic cell 43 through the main water intake channels 61 and 61b and the secondary water supply channel 62b.

  It is desirable that a throttle valve 61d is provided in the main water inlet 61b. Thereby, water flowing into the anode chamber (that is, water discharged as electrolytic oxygen water) is restricted, and effective use of water can be achieved. In this case, it is possible to reduce the size and cost of the electrolyzed water generating device 1 by making the main water intake passage 61b smaller in diameter than the main water intake passage 61a.

  In the present embodiment, a part of the main water intake channel 61a is arranged in the third side space 29, so that the first horizontal direction H1 space and the second electrolysis unit 41B with respect to the first electrolysis unit 41A. Thus, the water inlet 6 is not arranged in the space in the second horizontal direction H2. Thereby, when connecting and separating the first joint portion 84A, the third joint portion 84B, the first coupler 55A, and the second coupler 55B, interference between the operator's hand and tool and the water inlet 6 is suppressed, and electrolysis is performed.

The leading ends of the main water discharge channels 71a and 71b extend from the inside of the main body frame 2 to the outside. A main outlet 71 a from which the electrolytic hydrogen water is taken out is connected to the post-treatment device 300 outside the main body frame 2. The main water outlet 71 b from which the electrolytic oxygen water is taken out is connected to a drainage means (not shown) outside the main body frame 2.

  One end of the follower water channel 72a from which the electrolytic hydrogen water is taken out is connected to the cathode chamber of each electrolytic cell 43 (see FIGS. 4 to 6), and the other end joins the main water channel 71a. One end of the follower water channel 72b from which the electrolytic oxygen water is taken out is connected to the anode chamber of each electrolytic cell 43, and the other end joins the main water channel 71b. The electrolyzed hydrogen water electrolyzed in the cathode chamber of each electrolytic cell 43 flows into the post-treatment device 300 through the follower water channel 72a and the main water channel 71a sequentially. On the other hand, the electrolyzed hydrogen water electrolyzed in the anode chamber of each electrolytic tank 43 is discharged sequentially through the follower water channel 72b and the main water channel 71b.

  In the present embodiment, a part of the main outlet channel 71a is arranged in the third side space 29, so that the first horizontal direction H1 space and the second electrolytic unit 41B with respect to the first electrolytic unit 41A. Thus, the water discharge channel 7 is not arranged in the space in the second horizontal direction H2. Thereby, when connecting and separating the second joint portion 94A, the fourth joint portion 94B, the first coupler 55A, and the second coupler 55B, interference between the operator's hand and tool and the water discharge channel 7 is suppressed, and electrolysis is performed. Maintenance of the water generation unit 4 can be performed easily and in a short time.

  As shown in FIG. 2, it is desirable that the bottom portion 24 is provided with a dish-shaped water reservoir 8. The water reservoir 8 stores water that has leaked during maintenance of the electrolyzed water generator 4, the water inlet 6, and the water outlet 7.

  The drainage channel 7 is connected to the first drainage channel 73 for discharging the water extracted from the anode chamber of each electrolytic cell 43 to the outside of the main body frame 2 and the first drainage channel 73 extending from the water reservoir 8. It is desirable to further include a second drainage channel 74. The 1st drainage channel 73 is connected with the front-end | tip of the main outlet channel 71b. The main water discharge channel 71b and the first drainage channel 73 may be integrally formed. Since the second drainage channel 74 extending from the water reservoir 8 is connected to the first drainage channel 73, the water stored in the water reservoir 8 can be easily discharged.
