DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
In the electrolytic cell disclosed in Japanese Patent No. 32050, a stainless steel plate having the same size as a vinyl chloride plate (shell) is assembled by co-fastening, and each stainless steel plate reinforces each vinyl chloride plate, Although sufficient strength can be secured, weight increase is inevitable. This increase in weight becomes a problem to be solved especially when the electrolyzed water generating apparatus configured by using this electrolytic cell is used as a wall-mounted type.

Further, in the electrolytic cell disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 8-132050, the stainless plate has only the function of reinforcing the electrolytic cell, and therefore the above-mentioned Japanese Patent Application Laid-Open No.
As described in Japanese Patent Application Laid-Open No. 29255/1992, the electrical equipment box housed in the outer box together with the electrolytic cell must be separately assembled to the outer box via the bracket, and the number of components and the number of assembling work steps are reduced. The increase is inevitable. Also, in the above-mentioned electrical equipment box, electric parts for electrolyzing water in the electrolytic cell are housed, and a large amount of heat is generated in the electric parts. Consideration for heat treatment (radiation) Not done.

Therefore , or the reinforcing plate is stepped,
It is desirable to form a space through which air flows between the outer surface of each shell of the electrolytic cell or the outer surface of the electrical equipment box.

[0008]

In the electrolytic cell according to the present invention, the shell itself is reinforced by the bulging portion formed at the center of each shell, and the bulging portion is reinforced by the reinforcing plate.
The reinforcing plate only needs to have a size sufficient to reinforce the bulging part that is a part of the shell, and the reinforcing plate can be made smaller and lighter, and the electrolytic cell can be made smaller and lighter. Further, in carrying out the present invention, when the rib is formed inside the bulging portion or when the rib is formed outside the bulging portion of the shell, the bulging portion or the shell is reinforced by the rib. Therefore, the size and weight of the reinforcing plate can be further reduced.

Further, in the electrolyzed water producing apparatus according to the present invention constructed by using the above-mentioned electrolyzer, since the mounting portion of the electrical equipment box is integrally provided on the reinforcing plate, the number of constituent parts is reduced and the number of assembling steps is reduced. Can be reduced. Further, in the practice of the present invention, when the reinforcing plate is made of a good thermal conductor, the heat of the electrical equipment box (heat generated in the internal electric components) can be satisfactorily transferred to the electrolytic cell through the reinforcing plate. Thus, the water flowing through the electrolytic cell can efficiently absorb heat. In this case, if a rib is formed inside the bulging portion of the shell in the electrolytic cell, the rib can improve the heat exchange efficiency.

In the practice of the present invention, when the reinforcing plate has a stepped shape and a passage is formed to allow air to flow between the reinforcing plate and the electrolytic cell or between the electric component box and It is possible to absorb the heat of the electrical equipment box by the air flowing through, and it is possible to increase the heat dissipation area of the reinforcing plate and enhance the heat dissipation effect, and it is also possible to increase the rigidity of the reinforcing plate itself. Thin wall of the reinforcing plate, which is especially effective when the electrolyzed water generator is mounted on the wall.
The weight can be reduced. In this case, if ribs are formed on the outer side of the electrolytic cell except for the bulging portion of the shell, heat exchange efficiency can be increased by the ribs.
