is provided. Thus, the case 11, the water storage tank 14, and the receiver 15 are removably mounted on the mounting portion 10, and in the mounted state, the cutter 12 in the case 11 can be detachably connected to the rotating shaft 9a of the motor 9. connected. On the other hand, water storage tank 14
As shown in FIG. 1, a short cylindrical outlet body 16 and a valve element 17 for opening and closing the outlet body 16 are provided at the bottom of the outlet body 16, as shown in FIG. It is supported by an engaging claw 17a to be movable up and down on the outlet body 16. Reference numeral 18 denotes a connection port provided to insert and connect the outlet body 16 into the mounting portion 10 of the vessel body 1. A support plate portion 19 having a plurality of holes 19a is formed inside this connection port.
A protrusion 20 is formed at the center of the upper surface of the valve body for pushing the valve body 17 upward when the outlet body 16 is connected to the connecting port 18. Such connection port 1
8 is connected to the inlet end of the heating pipe 7 of the hot water generation mechanism 4 by a water supply pipe 21, and the hot water supply pipe 22 extending to the upper end of the vessel body 1 is connected to the outlet end of the heating pipe 7. A hot water supply arm 22a is connected to the upper end so as to be horizontally rotatable. In addition, 23 is case 11
A hot water diffuser shaped like a shallow container is attached to the upper opening of the hot water diffuser, and a plurality of hot water pouring holes 24 are formed at the bottom of the hot water diffuser. 25 is a lid that collectively covers the case 11 and the water storage tank 14.

Next, the operation of the above configuration will be explained. When extracting coffee liquid, open the lid 25,
Furthermore, after rotating the hot water supply arm 22a so as to remove it from above the case 11 and the water storage tank 14,
The case 11, water tank 14, and receiver 15 are removed from the mounting portion 10 by grasping the handle 14a and lifting it upward. Then, the valve body 17 at the bottom of the water storage tank 14 moves downward due to its own weight, and the outlet body 16 is closed. Then, after pouring water for the desired number of people into the water storage tank 14 from, for example, a water tap (not shown), the water storage tank 14 and the case 11 are attached to the attachment part 10. At this time, the valve body 17 comes into contact with the protrusion 20 of the connection port 18 and is moved upward, thereby opening the outlet body 16 and supplying the water in the water storage tank 14 to the heating pipe 7 of the hot water generation mechanism 4. Ru. Then, after putting coffee beans into the case 11, the hot water supply arm 22a is rotated to its original position on the case 11, and then the lid 25 is covered.
After that, the motor 9 is energized and the cutter 12 is rotated to grind the coffee beans, and then the motor 9 is turned off and the sheathed heater 6 is energized instead to generate heat, thereby preheating the bottle 8. At the same time, water supplied from the water storage tank 14 into the heating pipe 7 is heated to generate hot water. This hot water rises up the hot water supply pipe 22 due to boiling pressure and flows down from the hot water supply arm 22a onto the hot water diffuser 23, where it is diffused and drips into the case 11 from the hot water pouring hole 24. The dropped hot water permeates the coffee powder and extracts the coffee extract to become coffee liquid, and then is filtered by the filter 13 and dripped into the bottle 8 from the extraction port 15a and stored.

According to the above structure, since the water storage tank 14 is integrally formed in the case 11 which is detachably attached to the container body 1, it is possible to discard the coffee grounds remaining in the case 11 after extracting the coffee liquid. When cleaning the inside of the case 11,

That is, since the water storage tank 14 is removable from the container body 1 together with the case 11, there is no need to carry the container 1 when cleaning the water storage tank 14, and electrical components such as the sheathed heater 6 and the motor 9 inside the container 1 can be removed. Since there is no risk of water leakage, the water storage tank 1
The inside of the water storage tank 14 can be easily cleaned and has excellent cleaning properties, and the inside of the water storage tank 14 can always be kept clean. Furthermore, since the case 11 and the water storage tank 14 can be attached and detached from the vessel body 1 at the same time, the operability is superior to that in which these are separated. Also,
In particular, in this embodiment, since the water storage tank 14 is provided so as to surround the case 11,
The outer periphery of the case 11 has a double wall structure, which can reduce noise caused by the rotation of the cutter 12 during mill operation, especially when water is normally stored in the water storage tank 14 during mill operation. Therefore, the noise reduction effect is very excellent.

In this embodiment, the case 11 and the water storage tank 14 are integrated by integral molding, but the invention is not limited thereto. It may be integrated. In addition, in this embodiment, case 11
Although the water storage tank 14 is provided so as to surround the case, the structure is not limited to this, and the water storage tank may be provided on one side of the case, for example. In addition, the present invention can be modified in various ways without departing from the gist.
