In response to the operation on the mode selection switch 53, the timer 55 of the microcomputer 51 is set with a timer for inputting information on the extracted amount. Then, in response to turning on of the start switch 54, the boiling water heater 4 and the heat retention heater 18 are energized under the control of the microcomputer 51, and the boiling water heater 4 causes the tank 2
The water inside is heated.

When the temperature of the water in the tank 2 rises and boils as high-temperature hot water, the steam flows through the steam passage 7 and comes into contact with the steam sensor 8, whereby boiling of the hot water is detected and its signal is given. Is input to the microcomputer 51, and in response to this input, the timer 55 starts counting time, and the solenoid 17 is driven to operate.

By the operation of the solenoid 17, the hot water discharge valve 14 is pulled downward to open the hot water discharge port 5, and this state is continuously maintained. Then, when the hot water outlet 5 is opened, the high-temperature hot water in the tank 2 sequentially flows out continuously from the hot water outlet 5, and this hot water is guided through the guide pipe 12, the outlet 11, the through hole 36, ...
Through to the tea extraction container 21. At this time, the discharge port 25 at the bottom of the tea extraction container 21 is closed by the discharge valve 26. Therefore, the hot water that has flowed into the tea extraction container 21 is stored in the tea extraction container 21, and the tea The leaves are soaked.

When almost all of the hot water in the tank 2 flows out, the temperature of the hot plate 3 rapidly rises, and this temperature rise is detected by the temperature sensor 9. Then, the signal of this detection is input to the microcomputer 51, and on the basis of this signal, the water is heated and the heater 4 is de-energized.

The hot water stored in the tea extraction container 21 flows due to convection, and the black tea leaves also flow in response to the convection of the hot water, so that the black tea leaves are sufficiently dipped and shrunk. Is greatly opened, the extract component is effectively eluted, and black tea with a good taste is produced in the tea extraction container 21.
