[0025]
The drive means for the heat retaining container 11 includes a motor for driving the electric pump 27 and a power source for driving the motor. This power source may be a power source from the beverage extractor 1 serving as a power source for the storage battery 37 or the heat retaining heater 15 housed in the heat retaining container 11 or a power source from a household outlet. The storage battery 37 of the heat insulating container 11 is rapidly charged by energizing the power source from the beverage extractor 1 or the power source from the household outlet by the action of the electric circuit mechanism of the heat insulating container 11 by the microcomputer.
[0026]
When charging the storage battery 37, desired water is added to the water supply tank 2 of the beverage extractor 1, and high-temperature water corresponding to the additional water in the kettle tank 5 is sent into the chamber 9 by the siphon phenomenon and extracted. Charging is completed in about 3 to 5 minutes while dropping as a liquid from below the chamber 9.
[0027]
The storage battery 37 is provided with electric power to the electric pump 27 necessary to discharge all the extract liquid in the inner container 14 when the discharge switch 32 of the operation unit 36 is turned on when charging is completed. In this embodiment, a storage battery is used as the power source of the driving means. However, the present invention is not particularly limited to this storage battery, and there is no problem even if the storage battery is eliminated and power is obtained directly from a household outlet.
Reference numeral 38 denotes a temperature controller that senses the temperature of the liquid in the inner container 14 and transmits the detected temperature to an electric circuit mechanism by a microcomputer to turn the heat retaining heater 15 on and off.
[0028]
The liquid level display mechanism 21 includes a liquid level display tube 39 that rises along the outer wall of the inner container 14, a liquid level joint pipe 40 that connects the liquid level display tube 39 and the flowing water pipe 29, and the upper end of the liquid level display tube 39. And an upper joint pipe 41 communicating with the inside of the inner container 14. The liquid amount display tube 39 is visible from a transparent portion in which a transparent plate is pasted in a notch provided in the front vertical direction of the outer case 16.
[0029]
The upper joint pipe 41 has an inner diameter that is smaller than the inner diameter of the liquid amount display tube 39 and can discharge the internal air above the liquid amount display tube 39.
Since the liquid quantity joint pipe 40 communicates with the branch pipe 35 of the flowing water pipe 29 above the electric pump 27 of the discharge mechanism 20, the liquid quantity joint pipe 40 does not receive the water pressure of the electric pump 27. The liquid level can be confirmed easily without being greatly moved up and down.
