It can be easily lifted with both hands and removed from the main body frame 2.

One electrolytic unit 41 may be provided with a single handle 44. In this case, for example, in the first electrolysis unit 41A, it is desirable that the handle 44 is fixed to the base 42 on the side of the first horizontal direction H1 with respect to the electrolytic cell 43. As a result, the first electrolytic unit 41A can be easily pulled out by using the handle 44. Similarly, in the second electrolysis unit 41B, it is desirable that the handle 44 is fixed to the base 42 on the side of the second horizontal direction H2 with respect to the electrolytic cell 43.

As a result, a large number of electrolytic units 41 can be compactly housed inside the main body frame 2 in combination with the second horizontal direction H2 of the electrolyzed water generator 1 described above and the electrolytic units 41 arranged in the vertical direction.

The electrolyzed water generating unit 4 is fixed to the main body frame 2 so as to be closer to the fourth side portion 28 side of the main body frame 2. The above-mentioned "close to the fourth side portion 28 side" means that the center of the electrolyzed water generating portion 4 is offset toward the fourth side portion 28 side from the center of the main body frame 2. As a result, the electrolyzed water generating section 4 is integrated on the fourth side portion 28 side, and the large-capacity electrolyzed water generating section 4 can be compactly housed inside the main body frame 2.

On the other hand, the main portion of the electric cable 5 passes through the third side portion side space 29, which is the space between the electrolyzed water generating portion 4 and the third side portion 27, to connect the electrolyzed water generating portion 4 and the power supply portion 3.

One end of the sub water inlet pipe 62b branches from the main water inlet pipe 61b, 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 in sequence through the main water inlet pipes 61 and 61b and the sub water inlet pipe 62b.

It is desirable that the main water pipe 61b is provided with a throttle valve 61d. As a result, the water flowing into the anode chamber (that is, the water discharged as electrolytic oxygen water) is restricted, and the water can be effectively used. In this case, by making the main water pipe 61b smaller in diameter than the main water pipe 61a, it is possible to reduce the size and cost of the electrolyzed water generator 1.

In the present embodiment, a part of the main water pipe 61a is arranged in the third side space 29, so that the space in the first horizontal direction H1 with respect to the first electrolytic unit 41A and the space in the second electrolytic unit 41B are provided.
