イツチ48が開放し、止水弁8は閉弁する。 Next, the operation of the first embodiment of the steam configuration will be explained. First, the filter case 9 containing coffee powder and the filter 35 is placed on the cup 21, and then placed on the cup placement section 22. Next, water is poured into the water container 6 and the lid 12 is closed. Next, when the magnetic plug 29 is connected to the power stick 28 and the switch knob 44 is pushed in, the power switch 48 is closed and the heating element 7 and the heat-retaining heater 26 are energized. The water in the water container 6 is heated by the heating element 7 and its temperature rises to 100°C.
When the boiling point is reached, steam is continuously generated. Then, steam is ejected from the steam port 13 of the water container 6, and the steam detection element 3 is ejected from the opening hole 31 at the top of the steam detection tube 30.
It falls under 2. Then, the temperature of the vapor detection element 32 suddenly rises by 100 degrees Celsius compared to the atmospheric temperature, so that the compressed coil spring shape memory alloy has a restoring force to the memory-treated expanded state. It extends (Fig. 3 → Fig. 4). This movement overcomes the bias spring 33 to push down the slide rod 34 and rotate the valve lever 35 counterclockwise. Then, the other end of the valve lever 35 pushes up the valve stem 14 to open the water stop valve 8, and the hot water in the boiling water container 6 flows through the hot water supply path 10 to the coffee powder in the filter case 9 and the hot water diffuser 19. The molten metal is dispersed and poured evenly. At the same time, the protruding piece 37 of the valve lever 35 opens the power supply switch 38, and the valve lever 3
5 is locked in the depressed state by the locking lever 39, the subsequent electricity supply to the heating element 7 is stopped. Since the water stop valve 8 is also kept open, all of the hot water in the water container 6 is poured into the coffee grounds in 3 to 4 minutes, and the coffee liquid filtered by the filter 25 accumulates in the cup 21 to keep it warm. Heater 2
6 and thermostat 27 to keep the drink at a temperature suitable for drinking. Therefore, the hot water that is poured into the coffee powder can be supplied from the beginning with high-temperature boiling water and the extraction can be completed in a short period of time (3 to 4 minutes), making it possible to achieve delicious coffee extraction conditions. It is possible to satisfactorily obtain a rich, fragrant, and delicious coffee liquid that could not be obtained using conventional methods. or,
In the present invention, the user can easily understand the rotational movement of the valve lever 35 by checking the transparent display window 41 within the frame of the display board 40. That is, the water stop valve 8 switches from a closed state (e.g., closed/water pouring) to an open state (e.g., open/drip), so that the water stop valve 8 goes from boiling water in the water container 6 to open and supplying hot water to the coffee grounds. The condition can be easily determined without checking the pouring condition from the hot water supply port 18 or the like. This pouring state is sufficiently effective by solving the problem that the hot water supply port 18 is located in the center of the main body and is difficult to see visually, and that it is difficult to check when the amount of hot water poured before and after the hot water supply process is relatively small. Furthermore, since the timing of the start of hot water supply (the moment the valve is opened) can be immediately confirmed, the coffee extraction process can be understood and enjoyed in terms of time. Furthermore, there is a problem in that cold water drips when water is refilled if the valve is released from the open state. With this configuration, since the valve open and valve closed states are clearly displayed on the display window 40, this erroneous water injection can be prevented. Furthermore, if the font and color shown on the display window 41, the angle of the display window 41, and the lens configuration of the display window 41 are adopted, prevention of erroneous water injection will be promoted and the effect will be enhanced. On the other hand, the elongated steam detection element 32 stops ejecting steam from the steam port 13 due to power cut-off of the heating element 7, so when it is cooled by the atmosphere, it does not lose its restoring force and is pushed back by the bias spring 33 and returns to the close contact state. . After use, when the valve release knob 45 is operated, the switch knob 44 and the valve lever 35 are released from the locked state by the release piece 49, so they return to their original state, the power switch 48 opens, and the water stop valve 8 is released. is closed.
