No membrane electrolytic device

No membrane electrolytic device to produce subacid hypochlorous acid water, wherein the device comprises a housing (22) having a sealed inner space, a pair of electrode plates (10, 10′) disposed in the housing (22) to be opposite to each other, and a partition member (12) disposed between the electrode plates (10, 10′) to partition the inner space of the housing (22) into an electrolysis chamber (16) and a dilution chamber (24),

• the electrolysis chamber (16) having a hydrochloric acid inlet (18) on one side of it into which hydrochloric acid is introduced,
• the partition member (12) having passage (20) which introduces the chlorine gas produced by electrolyzing the hydrochloric acid in the electrolysis chamber (16) into the dilution chamber (24),
• the dilution chamber (24) having a dilution water inlet (26) on one side of it to supply dilution water in order to dissolve and dilute the chlorine gas, and a hypochlorous acid water outlet (28) on the other side of it to exhaust the hypochlorous acid water produced by dissolving the chlorine gas with the dilution water,
• the electrode plates (10, 10′) further including extending portions (10a, 10a′) extending toward the dilution chamber (24) so that the dilution water (24) introduced into the dilution chamber (24) could contact with the extending portions (10a, 10a′) of the electrode plates (10, 10′) and cool the electrode plates (10, 10′).
