Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a cooking appliance for general household use that performs grinding and cutting by rotating a cutter.

Conventional configurations and their problems Most conventional mixers have the configuration shown in Figures 5 and 6, in which a main shaft 2 supported by a bearing is used.
1 begins to rotate due to the rotation of the electric motor, the main shaft 2
Upper cutter 18 and lower cutter 19 fixed to 1
rotates, and as a result, the material contained in the cup 17 is stirred.

When the upper cutter 18 is placed horizontally as shown by the chain line 22, the crushability is improved but the cutting ability is decreased, and when the upper cutter 18 is set upright, the cutting ability is improved but the crushability is decreased.

OBJECTS OF THE INVENTION The present invention solves these conventional problems and provides a cooking device with improved crushing performance, cutting performance, and cutting power.

Structure of the Invention In the cooking device of the present invention, the cutter close to the bottom of the cooktop and the cutter located above the cutter have a curved shape, and one of the cutter blades located above the cutter blade extends upward from the horizontal plane. The other screw is twisted downward to make it easier for the material to be rolled up, thereby improving crushing and cutting properties.

DESCRIPTION OF EMBODIMENTS Examples of the present invention will be described below with reference to FIGS. 1 to 4.

In the drawings, 1 is a main body equipped with a motor and a switch, 2 is a tip plate detachably attached to the main body 1, 3 is a tip plate placed on the tip plate 2 and has a complicated rib 4 formed on the inner wall, and 5 is a tip plate. The outer cover is removably attached to the top 3 with screws, 6 is a bearing,
A bearing insert 7 is integrally molded, and an oil seal 8 and a bearing 9 are press-fitted into the bearing insert 7.

10 is a main shaft connected to the connector 11 by a screw, 12 is a lower cutter with a curved blade close to the bearing 6, and 13 is an upper cutter with a curved blade, one end 13a of which is in the horizontal plane of the cutter. On the other hand, the other end 13b is bent upward, and the other end 13b is bent downward, and the bending positions are such that the front edge is shorter than the rear edge and the center of the cutter with respect to the direction of rotation of the cutter.

That is, the bending state is such that the front edge is at a point a from the center of the cutter in the direction of rotation (solid arrow) in FIG. 3, and the rear edge is at a point b from the center of the cutter.
At the point (a<b), one end 13a moves upward by an angle θ, and the other end 13b moves downward by an angle α.
The material is stirred in the direction of the dotted arrow. 14 is a spacer for maintaining the distance between the upper cutter 13 and the lower cutter 12, 15 is an upper packing for preventing water leakage, and 16 is a lower packing.

Therefore, the rotation from the main body 1 is
The oil is transmitted through a bearing 6 supported by the bearing 6, an oil seal 8 press-fitted into an insert 7 integrally formed in the bearing 6, and a connector 11 screwed to the main shaft 10 supported by the bearing 9. The lower cutter 12 rotates to agitate the cutting material.

This stirring is caused by the material being rolled into the lower cutter 12 by the upwardly twisted end 13a of the upper cutter, and by the downwardly twisted end 13b.
The material is thrown upwards.

Now, looking at the relationship between the amount of displacement of the bending angles θ and α of the ends 13a and 13b of the upper cutter 13, the cutting performance, the crushability, and the winding time, it is as shown in FIG.

That is, by bending the end of the upper cutter 13, it is better to roll the material upward and downward, but it can be seen that the closer to the horizontal state the better the cutting and crushing properties are.

The performance in the conventional case is as shown in Figure 8.
It can be seen that when the upper cutter is set up, the cutting performance is improved, but the crushing performance is not good, and when the upper cutter is set horizontally, the crushing performance is improved, but the cutting performance is not good.

Effects of the Invention As described above, the present invention can provide a cooking device with good cutting and crushing properties by bending the end of the upper cutter.
