Abstract

PURPOSE:To improve cooking performance and enable the motor of low rotational frequency to be used and reduce noise by composing a device, of two kinds of an internal shaft rotary-cutting edge integrated with an internal shaft, and an external shaft rotary-cutting-edge integrated with an external shaft, so that the rotational directions may be different from each other. CONSTITUTION:By the rotation of the shaft 11a of a motor 1 and a first pulley 11b, a second pulley 15a and a hollow shaft 15 are rotated in the direction opposite to that of the shaft 11a, via a first belt 18, a second pulley 13, and a second belt 19. Along with the rotation, an internal connector 16 and an external connector 17 are rotated in the directions opposite to each other, and via an internal shaft connector 24 and an external shaft connector 25 engaged respectively with each other, an internal shaft rotary-cutting-edge 26 and an external shaft rotary-cutting-edge 27 are also rotated in the directions opposite to each other. By two pieces of the cutting edges to be rotated in the directions opposite to each other, a cooking object 30 contained in a vessel 28 is not to be rotated in the fixed direction due to the rotary cutting edges 26, 27 to be rotated in the directions opposite to each other. Accordingly, even with low rotational frequency, the relative speed of the cooking object is increased.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a rotary cooker for cutting and cooking vegetables and the like.

BACKGROUND OF THE INVENTION Conventionally, as shown in FIG. 2, this type of rotary cooker consists of a rotary cooker main body 3 having a built-in electric motor 1 and a switch 2, and a container 4 removably placed on the main body 3. However, the container 4 had a rotary blade 5 rotatably driven by the electric motor 1.

In the above configuration, by turning on the switch 2 and rotating the electric motor 1, the rotary blade 5 is rotated to cut and crush the food in the container 4.

Problems to be Solved by the Invention In such a conventional rotary cooker, since the cooking blade 5 rotates in one direction, the number of rotations had to be increased in order to improve cutting and grinding performance. however,
When the rotation speed increases, the bearings of the electric motor 1 become hot due to friction, and generate vibration noises, cutting and crushing noises inside the container, etc.
There were instances where the stirring noise and other noises were extremely loud.

The present invention solves the above-mentioned conventional problems, and aims to provide a rotary cooker with good cooking performance and low noise during cooking.

Means for Solving the Problems In order to achieve the above object, the present invention has a structure having a plurality of rotary blades that rotate in opposite directions on the same axis.

Effect: With the above-described configuration, the food to be cooked, which conventionally rotated in the same direction as the rotary blades, is no longer rotated in a fixed direction by the plurality of rotary blades that rotate in opposite directions.

Therefore, even at a low rotation speed, the relative speed of each rotary blade and the food to be cooked becomes large.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIG. Note that the same components as in the conventional example are given the same reference numerals, and their explanations will be omitted.

As shown in the figure, the output shaft 11a of the electric motor 1 has a first boo! J-11b is fixed, and the output shaft 11a passes through the hollow part of a hollow shaft 15 having a second pulley 15a. An inner connector 16 fixed to the output shaft 11a and an outer connector 17 fixed to the hollow shaft 15 are arranged on the upper surface of the main body 3. 1st boo IJ-1l b
A third pulley 13 is provided between the and second pulley 15a.
In this case, either the first belt 18 or the second belt 19 is crisscrossed so that the hollow shaft 15 rotates in opposite directions. A container stand 2o that is removably placed on the main body 3
A threaded portion is formed in the upper part of the
A hollow outer shaft 22 is rotatably supported, and an inner shaft 23 is rotatably mounted through the hollow portion of the outer shaft 22. An inner shaft connector 24 and an outer shaft connector 25 that engage with the connectors 16 and 17, respectively, are fixed to the lower ends of these shafts, and an inner shaft rotary blade 26 and an outer shaft rotary blade 27 are fixed to the upper ends. A substantially cylindrical glass container 28 with an open upper and lower surface has a threaded portion formed at the bottom opening, and is configured to engage with the threaded portion of the container stand 2o and integrate with the container stand 2o. There is. The top opening of the container 28 is covered by a removable lid 29.

To explain the operation in the above configuration, switch 2! ! !
- By rotating the shaft 11a of the electric motor 1 and the first pulley 11b, the first belt 18 and the second boot IJ-
13. The second pulley 15a and the hollow shaft 15 rotate in the opposite direction to the shaft 11a via the second belt 19. Accordingly, the inner connector 16 and the outer connector 17 rotate in opposite directions, and the inner connector 2 that is engaged with each other rotates in the opposite direction.
4 and the outer shaft connector 25, the inner rotary blade 26 and the outer rotary blade 27 also rotate in opposite directions.

Due to these two blades rotating in opposite directions, the food 3o placed in the container 28 is rotated by the rotating blades 26, which rotate in opposite directions,
2γ, it does not rotate in a constant direction. Therefore, even at low rotational speeds, the relative speed of each rotary blade and the food to be cooked is greater than in conventional rotary cookers.

Effects of the Invention As is clear from the above explanation, according to the present invention, the rotary blade is composed of two types: an inner rotary blade integrated with the inner shaft and an outer rotary blade integrated with the outer shaft. The rotary cooker has a structure with different rotational directions, which has good cooking performance, and allows the use of an electric motor with a low rotation speed, which produces less noise such as vibration noise, cutting and grinding noise in the container, and stirring noise. Can be provided.
