もなつていた。Construction 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 Figure 2.
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 rotational speed does not increase, which not only does not improve the cutting performance but also causes unnecessary power consumption.

電力も低減するものである。Composition of the Invention In order to achieve the above object, the cutter for a cooking machine of the present invention is provided with an inclination at the rear part of the cutter cutting edge in a direction opposite to the rake surface of the cutting edge, and an inclination toward the outside from the center of rotation of the cutter. The inclination angle α is kept constant and the inclination width is gradually increased.
According to 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 substantially reducing the strength of the cutter.In other words, the rotation speed of the cutter is increased. This not only improves cutting performance but also reduces power consumption.

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 20
An inclination 20c is provided at the rear of the cutting edge 20a in the opposite direction to the rake face 20b, and the inclination angle α is kept constant and the inclination width is gradually reduced outward from the rotation center D of the cutter 20. Therefore, at the rear of the cutter 20 rotating in the fluid,
Vortices are less likely to form. That is, rotation loss can be reduced and cutting performance can be improved. Furthermore, since the slope width is gradually increased 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 terms of strength, the bending moment is larger at the center of the cutter 20 than at the outside, so it is better to have a larger cross-sectional area.In this case, the width of the slope on the center side is gradually reduced. , the shape is similar to a beam of equal strength. In the embodiment, a straight line slope is used, but a curved line has the same effect.

る。Effects of the Invention As is clear from the above embodiments, the cutter for a cooking machine of the present invention has a rear part of the cutter cutting edge that is sloped in the opposite direction to the rake face of the cutting edge, and is sloped outward from the center of rotation of the cutter. , since this inclination angle α is kept constant and the inclination width is gradually increased, a sufficient cross-sectional area is secured at the center of the cutter where the bending moment is large, so that its strength is not impaired, and the circumferential speed is Since the inclination width gradually increases toward the larger outer circumference, vortex generation can be reliably and rationally suppressed to ensure smooth rotation. As a result, it is possible to improve cutting performance, reduce power consumption, and reduce noise during operation.
