2. Description of the Related Art In recent years, interest in water has become stronger in conjunction with nature and health consciousness, and famous water has been commercialized nationwide, and household water purifiers have become widespread. An electrolyzed water generator is provided to obtain. Also,
Strongly acidic water having a low pH and a high oxidation-reduction potential obtained by adding a small amount of chloride to water has excellent sterilization properties and is starting to attract attention in various fields such as medical care, food, animal husbandry, and agriculture. There are two types of electrolyzed water generators, a continuous type directly connected to a water supply and a water storage type.

[0003] The electrolyzed water generating device is configured to negatively charge water through a diaphragm.
When an electrode is formed by immersing the electrode in opposition to the positive and negative electrodes, and a current is passed through the electrode, the cations dissolved in the water move to the cathode side, the anions move to the anode side, and the water generated at the same time The water on the cathode side becomes alkaline water and the water on the anode side becomes acidic water by the electrolysis, and is used according to the purpose of use.

An electrolytic cell structure such as a structure in which a cylindrical diaphragm and a cylindrical cathode are arranged at a small interval on the outside, or a structure in which a plurality of electrode cells having the same structure are connected in parallel is employed.

[0005] In the case of the electrolytic cells of these continuous electrolyzed water generators, a plate-like electrode is disposed via a paper-like diaphragm to constitute a cathode cell and an anode cell, respectively. When performing lamination, water is supplied to each of the cathode cell and the anode cell separated by the diaphragm, and electricity is alternately supplied as a cathode / anode,
It is necessary to separate and take out the water from each of the cathode and anode cells.

On the other hand, in order to reduce the distance between the cathode and the anode in order to increase the electrolytic efficiency, each electrode tank has a narrow structure.
The structure of current supply to the electrodes in each electrode tank, the structure of water supply and extraction, etc. become more complicated as the number of electrode tanks is increased, obstructing the flow of water, uniforming the flow of water, and the There was a problem that separation was not reliably performed.

In view of the above, the applicant of the present application has previously disclosed in Japanese Patent Application No. 5-152711 a negative electrode and water through a diaphragm .

There is no need to configure an electrode tank, and an effect of enabling cost reduction can be obtained.

[0009]

However, according to Japanese Patent Application No. 5-152711, two separate electrode plates are provided for each electrode tank having the same structure.
