Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to an electric meat grinder for general household and commercial use.

BACKGROUND ART Conventionally, the storage box of this type of electric meat grinder is generally shaped like a lunch box, and is made of die-cast aluminum for hygiene and strength reasons. Also, its wall thickness is 2~
It was 3mm. Also, the connection to the Soufrieux body, which is also made from aluminum die-casting, is a taper fit. Further, the screw main body is also connected to a speed reducer and an electric motor.

Problems to be Solved by the Invention In such a conventional configuration, the vibrations of the electric motor and the vibrations of the gears in the reduction gear are transmitted to the storage box via the reduction gear and the screw body, just like a rattling device. Even small vibrations are magnified,
The storage box vibrates a lot. Furthermore, there was the problem of the harsh sound peculiar to aluminum die casting.

This invention solves these problems,
The purpose is to effectively prevent harsh sounds from storage boxes.

Means for Solving the Problem In order to solve this problem, the present invention is such that the thickness of the storage box is alternately formed into thick parts and thin parts.

Effect With this configuration, the vibrations generated by the electric motor and reduction gear are transmitted to the storage box via the screw body, but the wall thickness of this storage box is not constant, and thick and thin sections are formed alternately. Since a flange is formed at the open end, vibrations are absorbed and alleviated by the thick part. Since these are formed alternately, the harsh sound generated by repeated absorption and relaxation can be effectively eliminated.

Embodiment FIG. 1 is a sectional view of essential parts of an electric meat grinder according to an embodiment of the present invention. In FIG. Reference numeral 4 denotes a screw main body that incorporates a screw 5 having a spiral chevron connected to a transmission shaft 3a protruding from the reduction gear 3, a rotary cutter 6, and a fixed cutter 7. It can be attached to and detached from the main body 1 by screws or the like.
8 is a main body cover screwed into the front part of the screw main body 4.

A cylindrical injection hole 4a is integrally provided above the hole 4. A bento-shaped storage box 9 that is tapered and fitted is provided above it.

10 is a push rod for pushing mutton into the input hole 4a. The reduction gear 3, the screw body 4, the screw 5, and the storage box 9 are made of aluminum die-casting.

At the bottom of the storage box 9, thick parts 9a and thin parts 9b are alternately formed. Further, the opening end 9c is provided with a full-circumference flange 9d.

Next, the operation of this embodiment will be explained. Vibrations generated within the electric motor 2 and reduction gear 3 are transmitted through the screw body 4 and the insertion hole 4a to the storage box 9.
The sound is magnified and transmitted due to the ratuppa effect, producing a harsh sound. However, the wall thickness of this storage box 9 is not constant, and thick portions 9a and thin portions 9b are formed alternately. Furthermore, since a flange 9d is provided around the entire circumference of the opening end 9c, vibrations are absorbed and alleviated by this thick part 9a, and then transferred to the next part.
Here it is absorbed and relaxed again, moving on to the next part, where it is absorbed and relaxed again and becomes greatly reduced.
Furthermore, the flange 9d with the open end 9 further increases the rigidity, so that harsh sounds can be effectively prevented.

Effects of the invention As described above, according to the invention, the thickness of the storage box is formed by alternating thick and thin parts, so the vibrations generated by the electric motor and reduction gear are absorbed by the thick parts. will be eased. Since these are formed alternately, the amount of noise can be greatly reduced by repeating absorption and relaxation, making it possible to effectively eliminate harsh sounds.
