Depending on the state of the warming sensor 27, the extract warming means of the temperature control mechanism is activated, and the container 10 on the warmer 12 is heated.
The temperature of the extract is detected, and the low-temperature heater 3B is turned on and off by controlling the triac.

When extracting the extracted liquid, first, when water is supplied to the water supply tank 2, the water is collected in the water heater tank 5 via the water supply pipe 7. When the power is turned on, the hot water is heated by the hot plate 4 to bring the water in the tank 5 into a boiling state. Next, when the required amount of water is supplied to the water supply tank 2 in this boiling state, the water supply pipe 7
Hot water passes through the discharge pipe 9 by the siphon phenomenon by the amount of water supplied to the lower portion of the water heater tank 5 through
It is discharged into the chamber 8. Raw materials such as coffee powder and tea leaves are set in the chamber 8 in advance via filter paper, and flow down from the bottom of the chamber 8 as an extract. This extract is stored in the container 10, the container 10 is placed on the warmer 12, and when the switch is turned on, the extract in the container 10 is warmed by the low temperature heater 3B, so that the coffee is always warm.
