Technical Field

[0001] The present application relates to the field of food processing, and particularly to a cooking machine. Background Art

[0002] With the increasing improvement of people's living standards, many different types of cooking machines have emerged on the market. The functions of the cooking machine mainly can include, but are not limited to, making soymilk, squeezing fruit juice, mincing meat, making shaved ice, making coffee, and / or preparing facial masks, etc. The cooking machine can include machines for crushing food materials such as a soymilk machine, a blender, or a wall breaker. Existing cooking machines have problems of low crushing efficiency and inconvenient cleaning. Summary of the Utility Model

[0003] The purpose of the present application is to provide a cooking machine with high crushing efficiency for food materials and convenient cleaning.

[0004] The present application provides a cooking machine. The cooking machine includes: a stirring cup assembly, including a stirring cup and a chassis provided at the bottom of the stirring cup; a main body, including a driving mechanism and a driving shaft driven by the driving mechanism, the driving shaft passing upward through the chassis and extending into the stirring cup, and a first knife assembly being detachably provided at the top end of the driving shaft; and a flow disturbing knife assembly, including a rotating shaft and a second knife assembly, the rotating shaft being rotatably passed through the chassis without power drive, and the second knife assembly being detachably provided at the top end of the rotating shaft. When the cooking machine is working, the driving mechanism drives the driving shaft to rotate, so that the first knife assembly stirs and crushes the food materials in the stirring cup; meanwhile, during the process of the first knife assembly stirring the food materials, it causes the food materials to move in the stirring cup and then impact the second knife assembly, and then the rotating shaft drives the second knife assembly to rotate. The second knife assembly can not only play a role in disturbing the flow, but also stir and crush the food materials. In this way, the crushing efficiency of the food materials is higher; at the same time, the first knife assembly is detachably provided at the top end of the driving shaft, and the second knife assembly is detachably provided at the top end of the rotating shaft. After the cooking machine finishes working, the first knife assembly and the second knife assembly can be detached for cleaning, making it more convenient and thorough for the user to clean the cooking machine.

[0005] Further, the driving shaft includes a first driving section. The first driving section includes a plurality of first driving edges extending in the up-and-down direction. The plurality of first driving edges are gradually deflected circumferentially along the first driving section. The deflection direction of the plurality of first driving edges from bottom to top is opposite to the rotation direction of the first knife assembly. The first knife assembly is provided with a first driving hole matching the first driving section. The first driving hole includes a convex angle extending vertically in the up-and-down direction. In this way, the first driving edge has a downward limiting effect on the first knife assembly, so that the first knife assembly cannot axially disengage from the driving shaft upward during high-speed rotation. The rotating shaft includes a second driving section. The second driving section includes a plurality of second driving edges extending in the up-and-down direction. The plurality of second driving edges are gradually deflected circumferentially along the second driving section. The second knife assembly is provided with a second driving hole matching the second driving section. The second driving hole includes a convex angle extending vertically in the up-and-down direction. In this way, the second driving edge has a downward limiting effect on the second knife assembly, so that the second knife assembly cannot axially disengage from the driven shaft upward.

[0006] Further, the driving mechanism includes a motor and a gearbox. The gearbox includes a driving gear and a driven gear meshing with the driving gear. The driving gear is fixed to the output shaft of the motor, and the driven gear is fixed to the driving shaft. Through the cooperation of the driven gear and the driving gear, the driving shaft can achieve speed increase or decrease, and the structure is simple and reliable.

[0007] Further, both the driving gear and the driven gear are helical gears, and the normal module of the driving gear and the driven gear is between 1 and 2.5, the helix angle is between 15 degrees and 30 degrees, and the tooth thickness is between 5 millimeters and 30 millimeters. In this way, the transmission between the driving gear and the driven gear is more stable and reliable.

[0008] Further, the first knife assembly includes a first knife holder and a first knife blade arranged on the first knife holder. The second knife assembly includes a second knife holder and a second knife blade arranged on the second knife holder. The distance between the first knife blade and the second knife blade in the vertical direction is between 2 millimeters and 50 millimeters. In this way, the first knife blade and the second knife blade can crush the ingredients at different heights in the mixing cup, and the crushing efficiency can be further improved.

[0009] Further, the ratio of the center distance between the driving shaft and the rotating shaft to the inner diameter of the mixing cup is between 0.25 and 0.75. In this way, the first knife assembly and the second knife assembly can beat and crush the ingredients in the mixing cup within a large radial range, and the crushing effect is better. The ratio of the rotation speed of the driving shaft to the rotation speed of the output shaft is between 1 and 8. That is to say, speed increase is achieved through the gearbox, so a low-speed motor can be used, which can greatly reduce the noise of the food processor.

[0010] Further, the chassis is provided with a perforation through which the driving shaft and the rotating shaft pass, and a boss surrounding the perforation. By providing the boss, on the one hand, it is convenient to limit the driving shaft and the rotating shaft, and on the other hand, it increases the heat dissipation area and improves the phenomenon of bottom sticking.

[0011] Further, the driving mechanism includes a motor and a gearbox. The gearbox includes a box body and a cover body covering the box body. The rotating shaft passes through the cover body, and a bearing and a snap ring are provided between the rotating shaft and the cover body; and / or, the driving mechanism includes a motor and a gearbox. The gearbox includes a box body and a cover body covering the box body. The driving shaft passes through the cover body and the box body, and bearings and snap rings are provided between the driving shaft and the cover body and the box body respectively. In this way, the rotating shaft and the driving shaft can be positioned.

[0012] Further, the driving mechanism includes a motor, and the driving shaft is fixed to the output shaft of the motor. In this way, there is no need to set up a gearbox, which can reduce the volume of the cooking machine and lower the manufacturing cost.

[0013] Further, the first knife assembly includes a first knife holder and a first blade provided on the first knife holder, and the second knife assembly includes a second knife holder and a second blade provided on the second knife holder. The cutting edge orientations of both the first blade and the second blade are clockwise or both are counterclockwise. In this way, when the first knife assembly rotates, it can drive the ingredients in the mixing cup to impact the back of the second blade (the side opposite to the cutting edge of the second blade), thereby better driving the second knife assembly to rotate, making the second knife assembly have a better flow disturbance effect and being able to cut the ingredients more efficiently.
