Description

Technical Field

[0001] The utility model relates to the technical field of household electrical appliances, in particular to a food processing machine. Background Art

[0002] Existing food processors usually process food materials through cutting blades, which include a mounting plate and blade wings, wherein the blade wings are arranged on the mounting plate and the blade wings are driven to cut food materials by driving the mounting plate to rotate.

[0003] For example, Chinese utility model patent CN201558730U discloses a crushing blade, including a wing root and a blade connected to the wing root, wherein the geometric center of the wing root is provided with a mounting hole, the blades are distributed in a cross shape, and blades are provided on both sides of the upper surface of the blade. The blade of this structure is not only suitable for soybean milk machines that rotate in one direction to crush and pulp, but also suitable for soybean milk machines or rice paste machines that crush and pulp in forward and reverse directions, giving full play to the crushing function of the blade, and one pair of blades is bent upward or downward, the crushing space of the blade becomes larger, and the utilization rate of the blade is higher.

[0004] Another example is Chinese utility model patent CN211155391U, which discloses a knife, a knife assembly, a blending cup and a food processor, wherein the knife comprises a mounting plate and a knife wing, the rotation center axis of the knife passes through the mounting plate, the knife wing comprises a root, a middle part and a tip arranged in a radial direction, the root is connected to the mounting plate, and the middle part connects the tip and the root; the knife wing has a blade and a back arranged opposite to each other, the blade and the back are both located on the side of the knife wing and extend in the radial direction; the knife wing is twisted, one of the blade and the back faces upward and the other faces downward, and the knife wing is tilted relative to the mounting plate. By setting the tilted knife wing, the upper surface, the lower surface and the side of the knife wing can all contact the food and disturb the food, which can improve the disturbing effect of the knife wing on the food and improve the food crushing efficiency.

[0005] However, the above solution can only improve the crushing effect of food. During the use of the food processor, since the drive shaft is required to drive the mounting plate to rotate and thus drive the blade to rotate, the energy transmission path of the motor driving the blade needs to use the mounting plate as a medium, and the utilization efficiency of the driving force is not high, and it is easy to cause the drive shaft or the blade to shake, thereby affecting the stability of the food processor. Utility Model Content

[0006] The purpose of the present application is to provide a food processing machine to solve the problem of insufficient stability in existing food processing machines.

[0007] To achieve the above-mentioned purpose, the utility model provides a food processing machine, comprising a whipping cup and a cutting blade. The whipping cup has a receiving cavity. The cutting blade is arranged in the receiving cavity, the cutting blade comprises a mounting plate and a blade wing, the blade wing is connected to the mounting plate, the cutting blade rotates around the axis of the mounting plate, the blade wing has a first blade, the first blade has a first cutting edge line, the first cutting edge line is an arc segment, and the extension line of the first cutting edge line intersects with the axis of the mounting plate.

[0008] The blade wing of the cutting edge in the present application has a first blade, and the cutting line of the first blade is extended to intersect with the axis of the mounting plate, so that the extension line of the movement trajectory of the first blade passes through the center of rotation during rotation, which can effectively reduce the swing amplitude of the cutting blade and also reduce the swing amplitude of the power shaft that drives the cutting blade to rotate, thereby improving the efficiency of the mechanical transmission and improving the stability of the food processing machine.

[0020] In the present application, the second angle β between the first blade surface and the mounting plate meets the above conditions, so that when cleaning the food processor, the first blade surface can better splash the cleaning liquid upwards, thereby improving the cleaning effect and cleaning efficiency of the food processor.

[0021] In a preferred implementation of the food processor, along the radial direction of the whipping cup, there is a first distance L1 between the blade and the inner wall of the whipping cup, which satisfies the condition: 4 mm ≤ L1 ≤ 14 mm.

[0022] In the present application, the first distance L1 between the blade and the inner wall of the whipping cup meets the above conditions, which can effectively reduce the load power of the motor and also effectively reduce the noise of the whole machine.

[0067] In some embodiments, when the cutting edge 20 rotates along the first rotation direction X, the first blade 221 drives the food to move along the first rotation direction X in the accommodating cavity 11. When the first rotation direction X is switched to the second rotation direction Y, part of the food is driven by the second blade 222 to move along the second rotation direction Y. At this time, the food moving along the first rotation direction X collides with the food moving along the second rotation direction Y, and their relative speed is the sum of the rotation speed V1 and the rotation speed V2, so that the food can be crushed, thereby improving the cutting effect.
