Abstract: PURPOSE:To obtain an electrolytic ionized water generator which cleans an electrolytic tank by polarity inversion of both electrodes only if water feed is stopped an the electrolytic tank is drained by providing a control circuit which inverts the polarity of a first and a second electrode plate by turning a pressure switch OFF and rendering a detection terminal non-conductive. CONSTITUTION:A ionized water generator consists of a pressure switch arranged in a drinking water supply flow path to an electrolytic tank 2, paired detection terminals 34, 34a which detect the presence of water provided on the inner upper part of the electrolytic tank 2, and a control circuit which inverts the polarity of a first and a second electrode plate 12, 12a by turning the pressure switch OFF and rendering the detection terminals 34, 34a non-conductive. Consequently, if water feed is stopped to turn the pressure switch OFF and despite the stoppage, an area between the detection terminals 34, 34a is conductive, because water is not drained from the electrolytic tank 2, the polarity of a first and a second electrode 11, 12, 12, 12a is not inverter. In addition, if the detection terminals 34, 34a are found non-conductive due to the drain of water from the electrolytic tank 2, the polarity of the first and the second electrode 11, 12, 12, 12a is inverted to remove the sticking scale.
