This allows the lower container
Since 37 cools and the vapor pressure inside thereof falls to cause a vacuum action, the coffee liquid in the upper container 40 falls through the filter 41 and the water pipe 42 into the lower container 37 and is stored in the lower container 37. Therefore, after this, the upper container 40
The lower container 37 may be removed from the holder 18, and the removed lower container 37 may be tilted to transfer the coffee liquid to a coffee cup (not shown).

Thus, according to this embodiment, the lower container 37 is replaced by the upper container 40.
It is possible to perform the operation of moving the hot water inside and then separating it from the heater 17 by the actuating body 23, which does not require manual labor as in the conventional one, and thus frees the user from the trouble of the operation. You can do it, and it is convenient if you can. Further, in this case, since the operation is performed by the actuating body 23 without manual operation, the timing can be made constant, so that the taste of the coffee liquid can be made constant, and the coffee liquid can be always tasted deliciously.

In addition, the operating body 23 is made of a heat responsive member, and the lower container 37 can be separated from the heater 17 without requiring a complicated structure, so that the price can be kept low.

The upper container 40 removed from the lower container 37 after the extraction of the coffee liquid can be held by inserting the water passage 42 into the holder 18 as shown in FIG. 5, so that it may be difficult to place it. No, and at this time, the drop catches below
Since the 49 is located, the drops of the coffee liquid dripping through the water pipe 42 can be received by the drop receiver 49, and the table or the like is not polluted.

Further, although the present invention is applied to the coffee making machine in the above embodiments, the present invention can be similarly applied to other things such as tea making machines. In any case, the mechanism for crushing the raw material such as coffee beans does not necessarily have to be provided, and the operating body is not limited to the shape memory alloy.
