Description

[Detailed Description of the Invention] The object of the invention is to provide a filter which includes a motor and a rotary blade rotated by the motor, and which is located below the rotary blade and has a radial reinforcing member on its upper surface. This invention relates to an improvement of a coffee boiler consisting of an internal mill container and a hot water supply device for supplying hot water into the mill container, and is particularly aimed at efficiently grinding coffee beans and preventing filter clogging. .

The mill container used in the conventional coffee boiler of this type has a reinforcing member 19 disposed on the lower surface of the filter 15, as disclosed in Japanese Utility Model Application No. 55-13513, A sloped portion is formed on the upper surface of the member 19 to lift up coffee beans during grinding, but in such a structure, the coffee beans come into constant contact with the filter 15, resulting in damage. Easy and filter 15
This was causing clogging.

The present invention aims to improve such conventional drawbacks, and consists of a motor disposed on a part of the upper surface of the base, and a motor disposed detachably above the motor and rotated by the motor. It consists of a mill container in which a rotary blade and a filter having radial reinforcing members on the upper and lower surfaces below the rotary blade are installed, and a water heater that pours hot water into the mill container from above, and the reinforcing member is connected to the filter. The reinforcing member is disposed on the upper surface, and the upper surface portion of the reinforcing member is inclined so as to gradually rise in the direction of rotation of the rotary blade.

The operation is as follows: after storing coffee beans in the mill container, when the rotary blades are rotated by the motor, the coffee beans fly upwards on the inclined surface of the reinforcing member and efficiently hit the rotary blades and are crushed, as shown in Figure 3. Ru.

Therefore, the upper surface of the filter that is in most contact with the rotary blade is protected by the reinforcing member, and it is possible to prevent the filter from being damaged and from clogging. Furthermore, since the reinforcing member is used to lift the coffee beans, the coffee beans can be swept along the slope more efficiently than when using a conventional filter.

Next, embodiments will be described based on the drawings. 1 shows a schematic cross-sectional view of the coffee brewer of the present invention,
a base 3 having a heating means 2; a pot mounting part 5 formed by a heat insulating plate 4 on a part of the upper surface of the base 3;
A pot 6 for storing the finished coffee liquid,
A motor 7 disposed adjacent to the pot placement part 5, a storage part 8 that stores the motor 7, a recess 9 formed in the upper part of the storage part 8, and a pot that can be inserted into and removed from the recess 9. The basic structure includes a mill container 10 that is housed in a mill, a tank 11 that stores water, and the like.
A pipe 12 is connected to the bottom of the tank 11, the middle part of the pipe 12 is wrapped around the heating means 2, and the end part is positioned above the mill container 10. The mill container 10 has a rotary blade 13 that can be freely engaged with and detached from the rotating shaft 7a of the motor 7;
The rotary blade 13 includes a filter 15 located below the rotary blade 13, and a diffusion plate 16 that can open and close the upper opening. Moreover, the mill container 10
A communication portion 10 that communicates with the pot 6 is provided at the bottom of the pot.
It forms a. Reinforcing members 18, 19, etc. are attached to the upper and lower surfaces of the filter 15. The upper surface of the reinforcing member 18 disposed on the upper surface portion is inclined so as to gradually rise in the direction of rotation A of the rotary blade 13.

As explained above, the filter is strongly reinforced by the upper and lower reinforcing members so that it will not be damaged by the coffee beans being rotated and ground, and most of the filter surface is exposed because the reinforcing members are long. Since the coffee powder can be efficiently dropped and supplied downward, and the coffee beans are allowed to fly upward along the slope of the reinforcing member, the grinding efficiency is improved.
