もなつていた。Structure of conventional examples and their problems Conventional cutters for this type of cooking machine, especially mixer cutters that finely cut not only fruits but also vegetable fibers to make juices or grind foods, are As shown in the figure, in the cross-sectional shape of the cutter, the rear part A of the cutting edge 1 is rectangular, so the fluid flow is as shown in FIG.
A vortex is generated at the cutter rear A, resulting in a pressure drop and the cutter is subjected to a force from the fluid in the direction of flow. In other words, a loss occurs in the rotation of the cutter and the number of rotations does not increase.As a result, cutting performance not only does not improve, but also causes unnecessary power consumption.

With this configuration, it is possible to reduce the vortex generated at the rear of the cutting edge and reduce the loss of rotation of the cutter, without reducing the strength of the cutter. In other words, the rotational speed of the cutter increases, cutting performance improves, and power consumption also decreases.

傾斜としているが、曲線でも効果は同じである。 In the above configuration, as the cutter 20 rotates, the food 21 is agitated up and down while rotating, and is cut and crushed. In the case of the present invention, as shown in FIGS. 4 to 6, the cutter 2
A slope 20c is provided at the rear of the cutting edge 20a of the cutter 20 in the opposite direction to the rake face 20b, and the slope angle a is gradually reduced toward the outside from the rotation center D of the cutter 20, that is, a 1 Since < a 2 , vortices are less likely to occur at the rear of the cutter 20 rotating in the fluid. That is, rotation loss can be reduced and cutting performance can be improved.
Furthermore, since the inclination angle a is gradually reduced toward the outside of the cutter 20 where the circumferential speed is high and the wake resistance is greatest, it becomes more difficult for vortices to occur in the wake. In this case, near the center, the inclination angle a becomes large, a moderate amount of vortex is generated, and the rotation loss is small and a stirring effect is produced. In terms of strength, the bending moment is larger at the center than at the outside, so it is better to have a larger cross-sectional area, but in this case, since the angle of inclination is a 1 < a 2 , it is equal. It is shaped like a beam of strength. In the embodiment, a straight line slope is used, but a curved line has the same effect.

ものである。Effects of the Invention As is clear from the above embodiments, the cooking machine cutter of the present invention has an inclination at the rear part of the cutter cutting edge in a direction opposite to the rake face of the cutting edge, and this inclination angle a is set from the center of rotation of the cutter. Since the size gradually decreases toward the outside, it is possible to rotate smoothly without compromising the bending strength of the cutter or generating vortices at the rear of the cutter, resulting in improved cutting performance. At the same time, it is possible to reduce power consumption and noise during operation.
