Description

Technical Field

[0001] This 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 soy milk, squeezing 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 soy milk machine, a blender, or a wall-breaking cooking machine. Existing cooking machines have problems of low crushing efficiency and inconvenient cleaning. Content of the Utility Model

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

[0004] This application provides a cooking machine. The cooking machine includes: a stirring cup assembly, including a stirring cup and a chassis disposed at the bottom of the stirring cup; and a driving mechanism, including a main driving shaft and a secondary driving shaft that pass upward through the chassis and extend into the stirring cup. A main knife assembly is detachably provided at the top end of the main driving shaft, and a secondary knife assembly is detachably provided at the top end of the secondary driving shaft. Since the driving mechanism includes a main driving shaft and a secondary driving shaft, when the cooking machine is working, the main driving shaft drives the main knife assembly to rotate, and the secondary driving shaft drives the secondary knife assembly to rotate. That is to say, the main knife assembly and the secondary knife assembly simultaneously stir and crush the food materials in the stirring cup. Thus, the crushing efficiency for the food materials is higher; at the same time, since the main knife assembly is detachably provided at the top end of the main driving shaft and the secondary knife assembly is detachably provided at the top end of the secondary driving shaft, after the cooking machine finishes working, the main knife assembly and the secondary knife assembly can be detached for cleaning, making it more convenient and thorough for the user to clean the cooking machine.

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

[0006] Further, the drive 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 main drive shaft, and the driven gear is fixed to the slave drive shaft. The motor drives the main drive shaft to rotate. Through the cooperation of the driving gear and the driven gear, the main drive shaft and the slave drive shaft can output the same or different rotation speeds simultaneously, so as to realize the common crushing of food ingredients by the main knife assembly and the slave knife assembly, 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 drive mechanism includes a motor and a gearbox. A coating layer for heat insulation and noise reduction is provided outside the gearbox. By providing the coating layer, on the one hand, it isolates or reduces the heat conduction from the chassis to the gearbox, and on the other hand, it plays a role in shock absorption and noise reduction.

[0009] Further, both the main drive shaft and the slave drive shaft deviate from the center of the chassis. When the food processor is working, it can reduce the vortex formed by the food ingredients, thereby effectively reducing noise; in addition, it is beneficial to reduce the radial size of the mixing cup, and thus beneficial to the miniaturization of the product and cost saving.

[0010] Further, the main knife assembly includes a main knife holder and a main blade disposed on the main knife holder, and the secondary knife assembly includes a secondary knife holder and a secondary blade disposed on the secondary knife holder. The distance between the main blade and the secondary blade in the vertical direction is between 2 mm and 50 mm. In this way, the main blade and the secondary blade can crush ingredients at different heights in the mixing cup, further improving the crushing efficiency.

[0011] Further, the ratio of the center distance between the main drive shaft and the secondary drive shaft to the inner diameter of the mixing cup is between 0.25 and 0.75; and / or, the ratio of the rotational speed of the main knife assembly to the rotational speed of the secondary knife assembly is between 0.25 and 4. In this way, the main knife assembly and the secondary knife assembly can beat and crush the ingredients in the mixing cup within a large radial range, achieving a better crushing effect; and the main knife assembly and the secondary knife assembly can crush the ingredients more efficiently.

[0012] Further, the main drive shaft is located at the center of the chassis, and the secondary drive shaft deviates from the center of the chassis. In this way, the drive mechanism does not need to deviate too much from the chassis, or the drive mechanism can be roughly overlapped with the chassis, making the whole food processor smaller and facilitating the miniaturization of the food processor.

[0013] Further, the ratio of the center distance between the main drive shaft and the secondary drive shaft to the inner diameter of the mixing cup is between 0.25 and 0.5. In this way, the main knife assembly and the secondary knife assembly can beat and crush the ingredients in the mixing cup within a large radial range, while preventing the secondary knife assembly from hitting the mixing cup. The ratio of the rotational speed of the main knife assembly to the rotational speed of the secondary knife assembly is between 0.25 and 0.75. In this way, the noise can be better reduced.

[0014] Further, the chassis is provided with through holes for the main drive shaft and the secondary drive shaft to pass through and a boss surrounding the through holes. By providing the boss, on the one hand, it is convenient to limit the main drive shaft and the secondary drive shaft, and on the other hand, it increases the heat dissipation area and improves the phenomenon of bottom sticking.

[0024] Please refer to Figures 1 to 7 , the cooking machine 100 includes a mixing cup assembly 10, a drive mechanism 20, and a cup cover assembly 30. The mixing cup assembly 10 is assembled above the drive mechanism 20, and the cup cover assembly 30 is covered on the mixing cup assembly 10.

[0025] The stirring cup assembly 10 includes a stirring cup 11 and a chassis 12 disposed at the bottom of the stirring cup 11. The stirring cup 11 is used to hold food ingredients. In the illustrated embodiment, the chassis 12 is provided with a heating tube to heat the food ingredients in the stirring cup 11. In other embodiments, the chassis 12 is not provided with a heating tube and cannot heat the food ingredients.

[0026] The driving mechanism 20 includes a main drive shaft 21 and a slave drive shaft 22 that pass upward through the chassis 12 and extend into the stirring cup 11. A main knife assembly 211 is detachably provided at the top end of the main drive shaft 21, and a slave knife assembly 221 is detachably provided at the top end of the slave drive shaft 22. The driving mechanism 20 can drive the main drive shaft 21 and the slave drive shaft 22 to rotate, thereby driving the main knife assembly 211 and the slave knife assembly 221 to rotate. The main knife assembly 211 and the slave knife assembly 221 are used to beat and crush the food ingredients in the stirring cup 11. In the illustrated embodiment, the numbers of the main knife assembly 211 and the slave knife assembly 221 are each set to 1. In other embodiments, the numbers of the main knife assembly 211 and the slave knife assembly 221 are each set to 2 or more.

[0027] Since the driving mechanism 20 includes the main drive shaft 21 and the slave drive shaft 22, when the food processor 100 is operating, the main drive shaft 21 drives the main knife assembly 211 to rotate, and the slave drive shaft 22 drives the slave knife assembly 221 to rotate. That is to say, the main knife assembly 211 and the slave knife assembly 221 simultaneously beat and crush the food ingredients in the stirring cup 11. Thus, the crushing efficiency of the food ingredients is higher. At the same time, since the main knife assembly 211 is detachably provided at the top end of the main drive shaft 21 and the slave knife assembly 221 is detachably provided at the top end of the slave drive shaft 22, after the operation of the food processor 100 is finished, the main knife assembly 211 and the slave knife assembly 221 can be detached for cleaning, making it more convenient and thorough for the user to clean the food processor 100.

[0028] In the illustrated embodiment, the main drive shaft 21 includes a main drive section 212. The main drive section 212 includes a plurality of main drive edges 2121 extending in the up and down direction. The plurality of main drive edges 2121 are gradually deflected along the circumferential direction of the main drive section 212. The deflection direction of the plurality of main drive edges 2121 from bottom to top is opposite to the rotation direction of the main knife assembly 211. The main knife assembly 211 is provided with a main drive hole 2111 matching the main drive section 212. The main drive hole 2111 includes convex corners extending vertically in the up and down direction. Thus, the main drive edges 2121 have a downward limiting effect on the main knife assembly 211, so that the main knife assembly 211 cannot axially disengage from the main drive shaft 21 upward during high-speed rotation.

[0029] The slave drive shaft 22 includes a slave drive section 222, the slave drive section 222 includes a plurality of slave drive edges 2221 extending in the vertical direction, the plurality of slave drive edges 2221 are gradually deflected along the circumferential direction of the slave drive section 222, the deflection direction of the plurality of slave drive edges 2221 from bottom to top is opposite to the rotation direction of the slave knife assembly 221, the slave knife assembly 221 is provided with a slave drive hole 2211 matching the slave drive section 222, and the slave drive hole 2211 includes a convex angle extending vertically in the vertical direction. In this way, the slave drive edge 2221 has a downward limiting effect on the slave knife assembly 221, so that the slave knife assembly 221 cannot axially disengage from the slave drive shaft 22 upward during high-speed rotation.

[0030] In one embodiment, the drive mechanism 20 includes a motor 29 and a gearbox 28. The gearbox 28 includes a driving gear 281 and a driven gear 282 meshing with the driving gear 281. The driving gear 281 is fixed to the main drive shaft 21, the driven gear 282 is fixed to the slave drive shaft 22, and the motor 29 drives the main drive shaft 21 to rotate. Through the cooperation of the driving gear 281 and the driven gear 282, the main drive shaft 21 and the slave drive shaft 22 output the same or different rotational speeds simultaneously, so as to realize the crushing of food materials by the main knife assembly 211 and the slave knife assembly 221 together, and the structure is simple and reliable. The drive mechanism 20 includes a housing 27, and the motor 29 and the gearbox 28 are arranged in the housing 27.

[0031] Preferably, both the driving gear 281 and the driven gear 282 are helical gears, and the normal module of the driving gear 281 and the driven gear 282 is between 1 and 2.5, the helix angle is between 15 degrees and 30 degrees, and the tooth thickness is between 5 mm and 30 mm. In this way, the transmission between the driving gear 281 and the driven gear 282 is more stable and reliable.

[0033] The drive mechanism 20 includes a motor 29 and a gearbox 28, and a coating layer 280 for heat insulation and noise reduction is provided outside the gearbox 28. By providing the coating layer 280, on the one hand, the heat conduction from the chassis 12 to the gearbox 28 is isolated or reduced, and on the other hand, the functions of shock absorption and noise reduction are achieved.

[0034] In one embodiment, both the main drive shaft 21 and the secondary drive shaft 22 are offset from the center of the chassis 12. When the food processor 100 is operating, it can reduce the vortex formed by the ingredients, thereby effectively reducing noise; in addition, it is beneficial to reduce the radial size of the mixing cup, which is conducive to miniaturizing the product and saving costs.

[0035] The main knife assembly 211 includes a main knife holder 2119 and a main knife blade 2118 disposed on the main knife holder 2119. The secondary knife assembly 221 includes a secondary knife holder 2219 and a secondary knife blade 2218 disposed on the secondary knife holder 2219. Please refer to Figure 5 , the distance B between the main knife blade 2118 and the secondary knife blade 2218 in the vertical direction is between 2 millimeters and 50 millimeters. In this way, the main knife blade 2118 and the secondary knife blade 2218 can crush the ingredients at different heights in the mixing cup 11, which can further improve the crushing efficiency. In some embodiments, the distance B between the main knife blade 2118 and the secondary knife blade 2218 in the vertical direction can be 2 millimeters, 10 millimeters, 20 millimeters, 30 millimeters, 40 millimeters, 50 millimeters or a value between any two adjacent ones above.

[0036] Please refer to Figure 6 , the ratio of the center distance A between the main drive shaft 21 and the secondary drive shaft 22 to the inner diameter C of the mixing cup 11 is between 0.25 and 0.75. In this way, the main knife assembly 211 and the secondary knife assembly 221 can stir and crush the ingredients in the mixing cup 11 within a relatively large radial range, and the crushing effect is better. The ratio of the rotational speed of the main knife assembly 211 to the rotational speed of the secondary knife assembly 221 is between 0.25 and 4. In this way, the main knife assembly 211 and the secondary knife assembly 221 can crush the ingredients more efficiently.

[0037] In some embodiments, the ratio of the center distance A between the main drive shaft 21 and the secondary drive shaft 22 to the inner diameter C of the mixing cup 11 can be 0.25, 0.5, 0.75 or a value between any two adjacent ones above. The ratio of the rotational speed of the main knife assembly 211 to the rotational speed of the secondary knife assembly 221 can be 0.25, 1, 2, 3, 4 or a value between any two adjacent ones above.

[0038] Please refer to Figure 7 , the main drive shaft 21 is located at the center of the chassis 12, and the secondary drive shaft 22 is offset from the center of the chassis 12. In this way, the drive mechanism 20 does not need to deviate too much from the chassis 12, or the drive mechanism 20 can be substantially overlapped with the chassis 12, so that the overall size of the food processor 100 is smaller, which is conducive to miniaturizing the food processor 100.

[0039] The ratio of the center distance between the main drive shaft 21 and the slave drive shaft 22 to the inner diameter of the mixing cup 11 is between 0.25 and 0.5. In this way, the main knife assembly 211 and the slave knife assembly 221 can beat and crush the ingredients in the mixing cup 11 within a large radial range, while preventing the slave knife assembly 221 from hitting the mixing cup 11.

[0040] The ratio of the rotational speed of the slave knife assembly 221 to the rotational speed of the main knife assembly 211 is between 0.25 and 0.75. In this way, the noise can be better reduced.

[0041] The chassis 12 is provided with a through hole 126 for the main drive shaft 21 and the slave drive shaft 22 to pass through and a boss 125 surrounding the through hole 126. By providing the boss 125, on the one hand, it is convenient to limit the main drive shaft 21 and the slave drive shaft 22, and on the other hand, it increases the heat dissipation area and improves the phenomenon of bottom sticking.
