【Example】
An embodiment of the present invention will be described below with reference to FIG. A water storage tank 10 for storing water is provided in the main body 9. A water guide pipe 12 having a check valve 13 is provided at the bottom of the water storage tank 10. The check valve 13 acts so that water does not flow back into the water storage tank 10 from the water guide pipe 12 side. The water guide pipe 12 is heated by a heater constituting the heating means 11 below the extraction container 19 for extracting tea components from tea leaves provided at a predetermined position of the main body 9. The extraction container 19 is a server pot in this embodiment. The heating means 11 performs heating of the water guide pipe 12 and heating of the extraction container 19. Further, the water guide pipe 12 includes a water supply pipe 12 a that supplies water into the extraction container 19 via the switching valve 14 and a circulation pipe 12 b that similarly returns to the water storage tank 10 via the switching valve 14. That is, the water in the water storage tank 10 is circulated by the water guide pipe 12 and the circulation pipe 12b until reaching a predetermined temperature. When the water in the water storage tank 10 reaches a predetermined temperature, the switching valve 14 operates so that the water from the water guide pipe 12 passes through the water supply pipe 12a. The tip of the water supply pipe 12 a is a hot water supply port 20 for pouring water into the extraction container 19. The extraction container 19 is provided with a thermistor which is a boiling detection means 18. The boiling detection means 18 transmits this detected temperature information to the heating stop means 30, and the heating stop means 30 stops energization to the heating means 11 when receiving this information.
[0012]
Reference numeral 17 denotes a tea strainer for putting tea leaves, which is detachably held by the tea strainer holding member 23. The tea strainer holding member 23 is fixed to a sliding member 22 provided on a guide rod 21 fixed upright so as to be slidable in the vertical direction. The sliding member 22 is driven by a belt 26 that transmits the rotation of the motor 24 via a pulley 25. 27 and 28 are limit switches. The guide bar 21, the sliding member 22, the tea strainer holding member 23, the motor 24, the pulley 25, the limit switch 27, and the limit switch 28 constitute lifting / lowering means for lifting and lowering the tea strainer 17.
[0013]
The tea strainer 17 is always located at a position higher than the water supply pipe 12a so that the water splashed on the tea leaves placed in the tea strainer 17 at the time of water supply is prevented.
[0014]
The operation of this embodiment will be described below. The water stored in the water storage tank 10 is heated by the heating means 11 and circulates through the water guide pipe 12, the circulation pipe 12 b and the water storage tank 10, and the temperature rises. In this embodiment, the switching valve 14 is made of a shape memory alloy, and automatically guides water from the water guide pipe 12 to the water supply pipe 12a when the water in the water storage tank 10 reaches a predetermined temperature. The hot water that has reached a predetermined temperature is poured into the extraction container 19 through the hot water supply port 20. The hot water supplied at this time is such that the temperature falls to 80 ° C. to 90 ° C. by touching other parts of the equipment and the air. The boiling detection means 18 detects this temperature and transmits this information to a control device (not shown). The control device receives this information and energizes the heating means 11. Thus, the water in the extraction container 19 will boil again. When the boiling detection means 18 detects boiling, the control device transmits this information to the heating stop means 30 and stops energization of the heating means 11.
[0015]
At the same time, the control device drives the motor 24 for a predetermined time, lowers the tea strainer 17 containing tea leaves, and immerses it in the extraction container 19 for a predetermined time. That is, when the tea strainer 17 is lowered to a predetermined position, the limit switch 27 detects this and energization of the motor 24 is stopped. This soaking time is set in advance in the control device so as to be a time suitable for extracting tea components. When this immersion time has elapsed, the control device energizes the motor 24 again and raises the teacup 17 to a predetermined position. That is, when the tea strainer 17 rises to a predetermined height, the limit switch 28 detects this and stops energization of the motor 24. Therefore, in the extraction container 19, an extract from which tea components are extracted at an appropriate concentration is accumulated.
[0016]
As described above, according to this embodiment, the water in the water storage tank 10 once heated to the temperature is poured into the extraction container 19 and the extraction container 19 is heated, so that the water without the extraction container 19 is boiled in a short time. It can be made to. In addition, by using hot water immediately after boiling, the tea leaves are immersed for a predetermined time, and the tea leaves are automatically withdrawn from the extraction container 19 when the predetermined time elapses, so that the concentration of the extract increases. A tea dispenser that never goes too far.
[0017]
Further, since the belt is used as the lifting means of the tea strainer 17, there is no gear engagement sound, and the driving sound of the apparatus can be reduced. Further, there is no play such as backlash that occurs in the case of gears, and the tea dispenser can move very smoothly.
[0018]
Further, since the tea strainer 17 is always positioned above the hot water supply port 20 of the hot water supply pipe 12a, a predetermined amount of water is injected into the extraction container 19 and then immersed in the extraction container 19. Occasionally, tea strainer 17 does not take hot water, and tea components are not extracted by adding water to the tea leaves before soaking the tea leaves in boiling water. It is possible to realize a tea dispenser that can make
