PURPOSE: To improve the safety of the jar pot and to prolong the service life of an electric pump by ejecting the hot water by the electric pump at the hot water ejecting side and letting the electric pump at the circulating side to clean the liquid in a vessel.
CONSTITUTION: When the power is applied by keeping water 3 in a vessel 2 and closing a lid 26, boiling of water is started by controlling a control means 51 by the information from a temperature sensor 5 and generating heat by a heat generation body 4. In the lapse of the prescribed time, the amount of water is discriminated by the water temperature rise rate. When the temperature reaches the prescribed one, an electronic pump 16 starts the operation by the low voltage and is operated for the prescribed time by the amount of water. The water passes a circulating route different from the one which is used when the hot water is ejected. A discharge pipe 18 discharges the water to a space part 35 of a cleaning filter 32 mounted at the side of the lid 26. Thus, the smells of bleaching powder included in the water is reduced. Gradually, the water temperature rises and when finally it reaches a boiling point, the temperature of a sensor 49 rises to detect the boiling state. Then the energization of the heat generation body 4 is stopped and the device is switched to a warmth keeping state. A rock release key is pushed and a hot water eject key is pushed, then the hot water is ejected by the electronic pump 8.
