要であり、コーヒメーカを簡単に移動することが
困難で、しかも、設定場所にも制限がある。 Traditionally, this type of coffee maker has an automatic water supply system in which the water supply is directly connected to the hot water tank, a float installed inside the tank detects changes in the amount of hot water, and the water is always supplied from the tap in proportion to the amount of water that has decreased, so that the water level remains constant. is kept constant. For this reason, if the outlet provided in the hot water tank is opened for a certain period of time using a timer, etc., the set amount of hot water can be obtained accurately, but this requires piping to connect the water supply directly to the hot water tank, which requires a coffee maker. It is difficult to move easily, and there are also restrictions on where it can be set.

ヒ豆（図示せず）に注がれる。 Next, the operation of the coffee maker having the above configuration will be explained. First, the water supply door 21 is opened and water is poured into the hot water tank 3 from the water supply port 1'. As the amount of water stored in the hot water tank 3 increases, the weight of the hot water tank 3 increases, and the spring shaft 11 is pushed down to compress the compression spring 13. After the water supply is completed, the hot water tank 3 is held in a state displaced by a certain angle about the shaft 10.
When the power switch 24 is turned on, the heater 4a is energized and the water in the hot water supply tank 3 is heated to become hot water, and the temperature of the water is kept constant by the thermostat 4b. After the hot water reaches a predetermined temperature, a filter and the required number of cups of coffee beans are placed in the basket 18, the basket is inserted into the rail 19, and the scale of the capacity setting switch 25 is set to the required number of cups. When the glass container 20 is placed under the basket 18 and the start button 26 is pressed, the solenoid valve 14 opens, and after the time set by the capacity select switch 25, the solenoid valve 14 opened by a timer (not shown) closes. During this time, the hot water flowing out from the hot water supply tank 3 passes through the discharge port 15, is scattered by the scattering plate 16, and is poured onto the coffee beans (not shown) on the basket 18.

湯タンク３は圧縮バネ１３で一端を支持されてい
るため、バネの減衰作用により給湯タンク３内の
水の揺れは抑制される。 As the amount of hot water in the hot water tank 3 decreases, the weight of the hot water tank 3 decreases, so the compression spring 13
pushes up the extension spring shaft 11, and the hot water tank 3 is rotated about the shaft 10. Since the hot water supply tank 3 is displaced in this way, even if the amount of hot water in the hot water supply tank 3 decreases, the drop in the liquid level can be kept small. Furthermore, the flow rate of hot water from the hot water supply tank 3 can be stabilized, and means such as a feedback mechanism for stabilizing the flow rate, which has been conventionally used, become unnecessary. According to experiments, when the hot water supply tank 3 is fixed so as not to be displaced, the flow rate when the hot water supply tank with a volume of 5 is full changes from 550 c.c./min to 450 c.c./min after 4 outflows. On the other hand, if the hot water tank has the configuration of the present invention, the experimental results under the same conditions will be
It is possible to suppress the flow rate fluctuation to about 550c.c./min to 520c.c./min. Furthermore, when the coffee maker is transported on a wagon or the like or is used built into a wagon or the like, even if the coffee maker shakes, the hot water tank 3 is supported at one end by the compression spring 13, so the damping action of the spring causes the hot water tank to The swaying of the water inside 3 is suppressed.

る。 Then, the extracted coffee accumulates in the glass container 17, and if necessary, it can be kept warm by turning on the heat retention switch 24 and using the heat retention heater 14.
After use, when the drain switch (not shown) is operated, the drain solenoid valve 7 opens, and the hot water in the hot water tank 3 flows out of the main body 1 through the connection tube 6, the drain solenoid valve 7, and the drain pipe 8. Can be discharged.

で直接給湯タンク３を支持してもよい。 In addition, in the embodiment, one end of the hot water tank 3 is supported by the compression spring 13 and the spring tube 12 via the spring shaft 11, but the hot water tank 3 may be directly supported by another elastic member instead of the compression spring 13. .
