IONIZED WATER FORMING DEVICE

PURPOSE: To prevent a malfunction of a water discharge mode switching by surely detecting a temp. drop of an encoder whose temp. is risen under an influence of a heater for heating and regenerating an adsorbent. CONSTITUTION: This ionized water forming device is composed of a water treating device in which a water treating tank 4 is heated with a heater 14 to reproduce an adsorbent housed in its inside and an electrolytic cell 7 forming an alkali water and an acidic water by electrolyzing water supplied from the water treating tank 4. A temp. sensor 18 is disposed at a vicinity of the encoder 12 whose temp. is risen under the influence of the heater 14 for heating and regenerating the adsorbent in the water treating tank 4, and the mode switching action of a mode switching valve 10 based on a position detection with the encoder 12 is inhibited until a detected temp. becomes less than a fixed temp. In this way, the generation of the malfunction of the water discharge mode switching due to an action instability of a circuit element which is incidental to the encoder 12 at high temp. is prevented.
