The tap water to which sodium chloride introduced into the second electrolyzer 20 is added is electrolyzed by the power source 24 in the electrolyzer 22 between the electrode plates 21 in a non-membrane manner. Hypochlorous acid is generated by electrolysis, discharged as hypochlorous acid water from the discharge port 22b, and discharged from the hypochlorous acid water discharge port 61c.

  As described above, the electrolyzed water generating apparatus according to the present embodiment can select alkaline water and water by arbitrarily selecting the first opening / closing means, the second opening / closing means, and the flow path selecting means provided in the electrolyzed water generating apparatus. Four types of electrolyzed water, acidic water, hypochlorous acid water, and alkaline hypochlorous acid water, alkaline water and acidic water, alkaline water only, acidic water only, hypochlorous acid water only, alkaline hypochlorous acid water And the desired electrolyzed water can be obtained by selecting seven patterns of generation results of only acidic water / acidic water and hypochlorous acid water / alkaline hypochlorous acid water.

  In addition, although the electrolyzed water generating apparatus of this embodiment was provided with the 1st electrolytic vessel 12 and the 2nd electrolytic vessel 13, and demonstrated the case where the diaphragm 11a was arrange | positioned between a pair of electrode plates 11, it was mentioned above. As described above, when the three-chamber quadrupole diaphragm cell is used, the positions of the first opening / closing means 14, the second opening / closing means 23, and the valve means 62b, 62c and the opening / closing procedure can be changed as appropriate. It is apparent from the scope of the claims that the embodiments added with such changes or improvements can be included in the technical scope of the present invention.

It is a flowchart of the electrolyzed water generating apparatus concerning this embodiment.
