However, due to the large size of the traditional motor, the existing direct drive type food processor has a large height and weight, which affects the appearance and is not convenient to clean. CONTENT OF THE UTILITY MODEL

[0003] The purpose of the present application is to provide a food processor which can reduce noise while maintaining low height and light weight, so that the overall appearance of the food processor is more beautiful and easier to clean.

Since the motor body penetrates the through hole of the bottom disc, and the height of the motor body protruding upward from the bottom disc is between 0 mm and 70 mm, that is, only part of the motor body is located below the bottom disc, the stirring cup only needs a smaller space below the bottom disc to accommodate the brushless motor, so as to further reduce the height of the stirring cup assembly.

By arranging the bearing, the brushless motor is positioned to prevent it from swinging during operation.

[0011] Optionally, the upper surface of the motor body is flush with the upper surface of the bottom disc, or the motor body protrudes upward beyond the upper surface of the bottom disc. In this way, only part of the motor body is located below the bottom disc, and the stirring cup only needs a smaller space below the bottom disc to accommodate the brushless motor, thereby further reducing the height of the stirring cup and making the appearance of the food processor more beautiful.

[0012] Optionally, the brushless motor is mounted on the bottom disc through a motor support, the motor support comprises a support body and a first mounting portion, the brushless motor is fixed to the support body, and the mounting portion is fixed to the bottom disc.

[0015] Optionally, the stirring cup assembly comprises a control circuit board arranged in the stirring cup, and the control circuit board is electrically connected with the brushless motor. In this way, the control circuit board is arranged in the stirring cup, so that the base is not needed, and the overall structure of the food processor is simpler and the cost is lower.

[0016] Optionally, the stirring cup comprises a cup body and a cup seat, the bottom plate is clamped between the cup body and the cup seat, and the height of the cup seat is between 20 mm and 100 mm.

[0017] Optionally, the outer diameter of the brushless motor is between 20 mm and 75 mm, and the height of the brushless motor is between 20 mm and 75 mm. In this way, on the one hand, the brushless motor can provide sufficient power to drive the stirring blade to stir and crush the food material, and on the other hand, the volume and weight of the brushless motor are small, which can ensure the beautiful appearance of the food processor and facilitate cleaning.

[0018] Optionally, the ratio of the outer diameter of the brushless motor to the inner diameter of the stirring cup is not greater than 3 / 4.

[0032] Referring to Figures 1 to 7 The food processor 100 comprises a blending cup assembly 10, a brushless motor 20, a blending blade 30, and a cup cover assembly 50. The blending cup assembly 10 comprises a blending cup 11 and a base plate 12 arranged at the bottom end of the blending cup 11, wherein the base plate 12 is provided with a through hole 120. The blending cup 11 is used to place food materials. In the illustrated embodiment, the base plate 12 is provided with a heating tube, which can heat the food materials in the blending cup 11. In other embodiments, the base plate 12 can also not be provided with a heating tube.

[0033] The brushless motor 20 is assembled to the base plate 12, wherein the brushless motor 20 comprises a motor body 201 and a rotating shaft 202, the motor body 201 is arranged in the through hole 120, and the height of the motor body 201 protruding upward from the base plate 12 is between 0 mm and 70 mm.

[0034] The blending blade 30 is installed on the rotating shaft 202, and the blending blade 30 is driven by the brushless motor 20 to beat and crush the food materials. The blending blade 30 is fixed to the rotating shaft 202 by means of nuts, rivets, or the like. The blending blade 30 can be a single-blade or a multi-blade.

[0035] The height of the motor body 201 protruding upward from the bottom plate 12 can be 0 mm, 10 mm, 20 mm, 30 mm, 40 mm, 50 mm, 60 mm, 70 mm or any value between any two adjacent values.

[0036] The cooking machine 100 adopts the brushless motor 20. Since the motor body 201 is arranged in the through hole 120 of the bottom plate 12 and the height of the motor body 201 protruding upward from the bottom plate 12 is between 0 mm and 70 mm, that is, only part of the motor body 201 is below the bottom plate 12, the brushless motor 20 only needs a smaller space below the bottom plate 12 to be accommodated in the stirring cup 11. Therefore, the height of the stirring cup assembly 10 can be further reduced. In addition, the motor body 201 at least partially contacts the slurry, so that when the temperature of the brushless motor 20 is too high, the brushless motor 20 can be cooled by heat exchange with the slurry in the stirring cup 11.

[0037] The motor body 201 comprises an inner stator assembly 21 and an outer rotor assembly 22 sleeved on the inner stator assembly 21.

The stirring blade 30 is detachably mounted on the rotating shaft 202. Since the brushless motor 20 does not include a brush and a commutator, the brushless motor 20 has the characteristics of small height and light weight, thereby effectively reducing the overall height and weight of the cooking machine 100, making the appearance of the cooking machine 100 more simple, and making cleaning more labor-saving. At the same time, since the stirring blade 30 is detachably mounted on the rotating shaft 202, after use of the cooking machine 100, the stirring blade 30 can be detached, and the stirring blade 30 and the stirring cup assembly 10 can be cleaned respectively, so that the cleaning is more thorough and the hands are not hurt.

The stirring blade 30 comprises a driving hole 39 matched with the driving section 209. The driving hole 39 comprises a plurality of convex corners 391 extending vertically in the up-down direction. In this way, the convex edges 2091 deflecting in the circumferential direction of the driving section 209 have a downward limiting effect on the stirring blade 30, so that the stirring blade 30 cannot be separated from the rotating shaft 202 in the axial direction upward in high-speed rotation. In the illustrated embodiment, the stirring blade 30 comprises a blade holder 31 and a blade 32 fixed to the blade holder 31. The driving hole 39 is arranged on the blade holder 31 or the blade 32.
