PURPOSE:To automatically in every required times enable to prepare teat of a definite temp. only by a simple operation, by providing a thermal sensor and a water amount sensor in a kettle pot and by consisting a thermal exchanger part capable of warming by the hot water in the kettle pot, and the exchanger part thereof is a portion of a circulating path device of tea being operated by a circulating pump. CONSTITUTION:The bottom of an extracting pot 7 is connected to the intake side of a circulating pump 13 through a circulating pipe 17 and a circulating pipe 21 is connected to the exhaust side of the circulating pump 13 and the end side of a hot water supply pipe 15 and a supply-circulation pipe 18 in common so that the end of the circulating pipe is opened above an extracting tray 5. A portion of the circulating pipe 17 is drawn into a kettle pot 3 to constitute a heat exchanger 19 for warming that portion with hot water in the kettle pot 3. A heater 47 for boiling water accumulated in said pot 3 is provided on the bottom of said pot 3. A water amount sensor detects whether or not said water reaches at least a predetermined amount. A temperature sensor for detecting the temperature of hot water in the kettle pot 3 is provided on the bottom thereof. |
