Description of the Related Art As shown in FIG. 3, an electrolytic aid such as sodium chloride (NaCl) or potassium chloride (KCl) is added to an electrolytic cell 1 in which a plus electrode 2 and a minus electrode 3 are installed facing each other. BACKGROUND ART An electrolyzed water supply device that supplies water and applies a DC voltage between electrodes 2 and 3 to electrolyze the water to generate acidic water or alkaline water is generally known. In this case, acidic water containing hypochlorous acid (HClO), which is a sterilizing component, is generated on the positive electrode side, and alkaline water is generated on the negative electrode side.
These electrolyzed waters are separated from each other by a separation plate 4, and the acidic water is taken out of the tank from the outlet 1a and the alkaline water is taken out of the tank from the outlet 1b. For the use of electrolyzed water, acid water with a bactericidal action remains as acidic water,
Alternatively, as weakly acidic water (pH 5 to 6), it is used for medical sterilization and hand disinfection, and alkaline water having a cleaning action is used for cleaning instruments and the like.

It is also known that the alkaline water is discarded as waste water to cause waste. Therefore, the generated acidic water and alkaline water are mixed again and used as mixed water. This mixed water shows weak alkalinity, and sterilizing power is not as strong as acidic water, but it contains hypochlorous acid, so it has a bactericidal action in addition to the washing action, and is stored in a tank to wash food etc. It is used for
