Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to an electric cooking machine for cutting food materials such as vegetables, for example, in ordinary households.

Conventional Structure and Problems When cutting food materials such as vegetables, electric cooking machines that automatically cut the food materials are generally used. Generally, an electric cooking machine has a container into which food materials are put, and the container is placed on a main body that includes a built-in electric motor. A cutter for cutting the food material is housed in the container and is transmission connected to the electric motor of the main body.
As shown in FIG. 1, the cutter 1 consists of a knife blade 2 and a mounting base 3 for the knife blade 2.
has a cutting edge 4 at the tip and is fixed to a mounting base 3. This cooking machine uses the electric motor in the main unit to make one cut.
The knife blade 2 of the cutter 1 stirs food materials such as vegetables in a container and cuts the food materials with the cutting edge 4 of the knife blade 2. I can do it. Not only vegetables, but also meat, for example, can be cut.
You can also mince it.

By the way, as the cutter 1 of this type of electric cooking machine, conventionally, a cutter 1 in which two knife blades 2 are arranged in two upper and lower stages is used. However, desired cutting performance could not be obtained, and the material could not be uniformly cut in a short time. The reason for this is believed to be that the food material is only stirred by the two knife blades 2 and cut by their cutting edges 4. For this reason, it is not possible to obtain a sufficiently large stirring force,
It was not possible to cut the material uniformly in a short time.

Purpose of the Invention Therefore, the present invention solves the above-mentioned conventional problems in an electric cooking machine in which a cutter is rotationally driven around a substantially vertical axis by an electric motor, and cuts food materials uniformly in a short time. It was done for that purpose.

SUMMARY OF THE INVENTION The present invention provides a cutter of an electric cooking machine with at least three knife blades extending radially at angular intervals about its vertical axis. Then, the knife blades are arranged in three different levels, one above the other, and among these knife blades, the lower and middle knife blades have a cutting edge with an inclined upper surface, and the upper knife blade has a cutting edge with an inclined lower surface. It is characterized by being long-lasting.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 2 shows an embodiment of the invention. This cooking machine includes a main body 6 having a built-in electric motor 5 and a container 7 into which food materials are put, and the container 7 is removably placed on the main body 6. The main body 6 has a back plate 9 to which legs 8 are attached. The container 7 has an opening covered by a lid 10, and the lid 10 is removably fitted into the opening of the container 7.

The electric motor 5 is attached to the chassis 12 with screws 11, and the chassis 12 is attached to the main body 6 with screws 13. Drive shaft 1 of electric motor 5
4 is a small pulley 15, a belt 16 and a large pulley 1
It is transmission connected to the main shaft 18 via 7. The main shaft 18 is arranged substantially vertically and is attached to the chassis 12 and the body 6 by an oilless bearing 19 and a rubber coupling 20, and is attached to the container 7.
protrudes inward. Furthermore, a connector 21 is provided on the outer peripheral surface of the main shaft 18 within the container 7 .

The cutter 22 has three flat knife blades 2.
3 and is housed in a container 7. The mounting base 24 of the knife blade 23 is cylindrical and is arranged concentrically with the main shaft 18, and each knife blade 23 extends in the radial direction at angular intervals around the main shaft 18, and is attached to the outer peripheral surface of the mounting base 24. Fixed. The connector 21 of the main shaft 18 is inserted into the mount 24, and the upper end of the connector 21 is fitted into the groove of the mount 24 so that the torque of the main shaft 18 can be transmitted. Thereby, the cutter 22 is transmission connected to the main shaft 18 and the electric motor 5.

As shown in FIGS. 3 and 4, the knife blades 23 are arranged in three different levels, the lower and middle knife blades 23 have cutting edges 25L and 25M with inclined upper surfaces, and the upper knife blades 23 have cutting edges 25L and 25M with inclined upper surfaces. 23 has a cutting edge 25H with an inclined lower surface.

When cutting food materials such as vegetables in the electric cooking machine configured as described above, the container 7 is first placed on the main body 6, the lid 10 is removed from the opening of the container 7, and the cutter is cut. 22 into the container 7. Then, when the mounting base 24 of the cutter 22 is placed over the connector 21 of the main shaft 18 and the upper end of the connector 21 is fitted into the groove of the mounting base 24, the cutter 22
can be supported by the main shaft 18 and the connector 21. Next, the food material may be put into the container 7, and the lid 10 may be fitted into the opening of the container 7. Thereafter, when the electric motor 5 is energized, the torque of the drive shaft 14 is applied to the mounting base 22 of the cutter 22 by the pulleys 15, 17, the main shaft 18, and the connector 21.
transmitted to. This drives the cutter 22 rotationally about a substantially vertical axis. The mount 24 of the cutter 22 rotates integrally with the connector 21 of the main shaft 18, and each knife blade 23 rotates integrally with the mount 24. Therefore, the food material is stirred in the container 7 by the knife blade 23 of the cutter 22, and the cutting edges 25L, 25 of the knife blade 23 are stirred.
Cut by M, 25H.

In this cooking machine, the lower, middle and upper knife blades 23 rotate at angular intervals around a substantially vertical axis, the food material is stirred by these three knife blades 23, and the three knives Cutting is performed by the cutting edges 25L, 25M, and 25H of the blade 23. Therefore, a sufficiently large stirring force can be obtained. The cutting action of the cutting edges 25L, 25M, and 25H of the knife blade 23 is also distributed evenly throughout the container 7. Furthermore, food materials tend to descend due to their own weight and be pressed against the bottom surface of the container 7, but this cooking machine has the cutting edges of the lower and middle knife blades 23, that is, the cutting edges 25L and 25M whose upper surfaces are sloped. It acts to push up food materials. The food material is pushed up by the cutting edge 25L of the lower knife blade 23, and further pushed up by the cutting edge 25M of the middle knife blade 23. Therefore, the tendency for the food material to fall is reduced. Upper knife blade 23
The cutting edge 25H, which has an inclined lower surface, has the opposite effect of pushing down the food material. Therefore, the food material is concentrated at the height positions of the cutting edges 25L, 25M, and 25H of the lower, middle, and upper knife blades 23, and is effectively stirred and cut. As a result, the food material can be uniformly cut in a short time.

In this embodiment, three knife blades are arranged in three different stages, but the number of knife blades does not necessarily have to be three. For example, two knife blades may be provided as the lower knife blades, and a total of four knife blades may be arranged in three upper and lower stages. Five or more knife blades may be arranged in three different stages, one above the other.

Effects of the Invention As explained above, the present invention provides at least three knife blades that extend in the radial direction at angular intervals around a vertical axis and are arranged in three different stages, the lower and middle knife blades. The upper knife blade has a cutting edge with an inclined upper surface, and the upper knife blade has a cutting edge with an inclined lower surface.
Food materials can be cut uniformly in a short time,
It is possible to achieve the intended purpose.
