The problem to be solved by the present invention relates to an electrolyzer used in the method of producing sterilizing water by electrolytic oxidation of chloride ion solution in an electrolyzer and dilution of electrolytic oxidation solution with water. It provides an electrolyzer with less temperature rise, lower operation cost and better economy even with larger capacity. The invention aims at solving the above problems: (1) setting the electrode plate as bipolar or unipolar to achieve high concentration of hypochlorite. (2) In order to eliminate the concentration spot of electrolyte which is the cause of eccentric wear of electrolytic current spot and electrode plate, a mixing function is set at the lower part of the electrolytic cell. (3) An electrolytic cell which can replace the electrode plate is set up. Even at the end of its life, only the replacement of the electrode plate is carried out to realize the regeneration of the electrolytic cell. Through the above scheme, the generating method and device of electrolytic water with lower operation cost and better economy are provided.
