(Problem that the invention attempts to solve) However, in the above-mentioned coffee maker,
It is difficult to use the coffee maker only when it is suspended from the bottom of a kitchen shelf, etc., and if you try to remove it from the shelf and place it on a table, etc., it will be damaged due to the load caused by that placement. , the support stand rotated relative to the support rod, and the support rod also rotated relative to the main body, making it impossible to place the coffee maker in its proper position. The problem was that it had to be used in a closed state. Also, even when used in a suspended state,
If an external force is carelessly applied from below the support, the support will rotate and tilt, causing the coffee liquid in the bottle to spill out. This invention aims to solve these problems.

[Structure of the device] (Means for solving the problem) In order to solve the problem, this device is equipped with a water storage chamber and a heating mechanism that sequentially heats the water in the water storage chamber to make hot water. Further, a support rod is rotatably attached to the lower surface of the main body holding the extractor for extracting coffee liquid using hot water from the heating mechanism to support it vertically, and a bottle is placed on the lower end of the support rod. A support stand is rotatably attached to support it horizontally, the support stand is rotated to close it to the support rod, and the support rod is further rotated to close it to the bottom surface of the main body and folded. A locking mechanism that locks the support rod in a vertical position is provided between the support rod and the main body, and a lock mechanism that locks the support rod in a horizontal position is provided between the support stand and the support rod. are provided for each.

(Function) The lock mechanism prevents the support stand from rotating relative to the support rod, and the support rod from rotating relative to the main body, thereby preventing inadvertent external forces from below the support stand when the coffee maker is suspended. Even if the coffee maker is placed on a table, the support stand and support rod are prevented from rotating, so even if the coffee maker is placed on a table, etc., it is prevented from tilting. It becomes possible to use it.

Then, the bottle 40 is placed on the placing portion 30 of the support stand 28, and the extractor 16 is attached to the lower surface of the main body 1 via the rails 15, 15. Note that when rotating the support rod with respect to the protruding piece 25 and when rotating the support stand 28 with respect to the support rod 27, the lock pieces 43, 4
The tips of the lock pieces 43 and 45 slide against the protrusion 25 and the support rod 27, but since the tips of the lock pieces 43 and 45 are inclined, the tips of the lock pieces 43 and 45 do not come into contact with the protrusion 25 and the support rod 27. The area of the support rod 27 is kept small, thus reducing frictional resistance.
The rotation of the support base 28 and the rotation of the support base 28 can be performed smoothly.

In this way, under normal use of the coffee maker, the folding of the coffee maker is prevented via the lock pieces 43 and 45, and therefore, when the coffee maker is suspended from the bottom surface of the shelf board a. ,
Even if an external force is inadvertently applied from below the support stand 28, the support stand 28 will tilt and the bottle 4
There is no problem such as spilling the coffee liquid in the cup. Furthermore, even when the coffee maker is removed from the bottom surface of the shelf board a and placed on a table, etc., the support stand 28 and the support rod 2
