The microcomputer 101 performs control operation according to various inputs to the input section. First, when the power is turned on, the heat retention temperature is set to, for example, the high temperature side coffee selection state by the initial setting. Then, when water is put into the hot water storage container A, it is boiled because it is below the heat retention temperature. When the content liquid boils, the heat retaining state is switched to the heat retaining temperature. Then, when the reboil key 132 is operated, the content liquid is boiled again, and then the heat retaining state is switched again.
It can be used as it is like a normal electric pot. The heat retaining plate B is not particularly necessary only for such an application. In addition, the heat retaining structure can be omitted even when provided.

Whether the pouring is continuous pouring depending on the use and the required amount,
Whether or not a fixed amount is to be dispensed in the number of people
Can be selected and executed by the selecting operation.

When extracting coffee, tea, or the like, the extractor heat retention key 139 is operated to turn on the heater 123 in the heat insulation plate B (it is turned off again when operated again).
