PURPOSE:To alternately discharge hot water and cold water by comparing a signal received from a temperature senser with both high and low setting temperatures, and alternately feeding an actuating signal of the high setting temperature and an actuating signal of the low setting temperature in a cyclic manner. CONSTITUTION:In the way of a mixed water passage 7 leading to a nozzle 10, a temperature senser 8 is disposed, and the detected temperature is transduced into an electrical signal which is fed to a controlling section 9. The controlling section 9 is electrically connected to actuating sections 5, 5, and compares the high and low setting temperatures upon receiving the electrical signal from the temperature senser 8 so as to alternately feed an operating signal that adjusts the opening ratio of a water valve 2 and a hot water valve 4 to the high setting temperature and an operating signal that adjust the opening ratio to the low setting temperature. The opening ratio of the water valve 2 and the hot water valve 4 is alternately adjusted in a cyclic manner to the high and low setting temperatures, which is automatically controlled.
