A water temperature control device in a hot water supply tank of a hot water storage type bidet is provided to keep the whole water in a hot water supply tank at the uniform temperature, to shorten the time required for heating up the water within the range of the specific temperature and to increase the quantity of hot water for a hot water storage type bidet user to use continuously by circulating the water of an outlet and the water of an inlet compulsively using an oscillator. The water temperature control device in a hot water supply tank of a hot water storage type bidet comprises a water level sensor(20) installed on the top of a hot water supply tank(10) of a hot water storage type bidet to sense the water level in the hot water supply tank, a primary temperature sensor(21a) installed around an outlet(14) of the hot water supply tank to sense the temperature of water stored in the hot water supply tank, a secondary temperature sensor(21b) installed around an inlet(11) of the hot water supply tank to sense the temperature of water stored in the hot water supply tank, a hot water heater(22) installed in the hot water supply tank to heat up the water stored in the hot water supply tank within the range of the specific temperature, an oscillator(22a) installed on the bottom of the hot water supply tank to circulate the water stored in the hot water supply tank compulsively, and a hot water heater driver(23a) operating the hot water heater if the water level sensing signal of the water level sensor indicates the water level above the specific level, operating the hot water heater if the temperature sensing signal of the primary temperature sensor deviates from the range of the specific temperature and operating the oscillator if a difference between the temperature sensing signal of the primary temperature sensor and the temperature sensing signal of the secondary temperature sensor deviates from the range of the preset temperature whenever the inlet and the outlet of the hot water supply tank open while the hot water heater is operating. |
