Description

Technical Field

[0001] This application relates to the field of food processing, and more particularly to a food processor. Background Technology

[0002] With the continuous improvement of people's living standards, many different types of food processors have appeared on the market. The functions of food processors mainly include, but are not limited to, making soy milk, juicing, rice paste, mincing meat, shaved ice, making coffee, and / or preparing face masks. Food processors can include soy milk makers, blenders, or high-speed blenders—machines that pulverize and mix food. The mixing blades of existing food processors are usually located at the bottom of the mixing cup and cannot be removed for cleaning, making cleaning inconvenient and potentially causing injury. Additionally, because existing food processors use a motor shaft to drive the mixing blades, the overall height of the food processor is relatively high. Utility Model Content

[0003] This application provides a food processor that is easy to clean after use and has a low profile.

[0004] This application provides a food processor. The food processor includes: a blending cup assembly, comprising a blending cup and a base disposed at the bottom of the blending cup; a shaftless motor disposed within the blending cup, the shaftless motor including a motor stator and a motor rotor, the motor stator having a through hole extending vertically, and the motor rotor disposed within the through hole; and a blade assembly detachably assembled to the motor rotor, and the blade assembly being able to rotate together with the motor rotor. Because the blade assembly is detachably assembled to the motor rotor, it can be disassembled for cleaning after use, resulting in more thorough cleaning and reducing the risk of hand injury. Furthermore, by placing the shaftless motor within the blending cup and using the motor rotor to drive the blade assembly, the overall height of the food processor can be effectively reduced, thus facilitating miniaturization of the food processor.

[0005] Furthermore, the motor stator includes a stator support and a coil assembly disposed on the stator support, and the motor rotor includes a rotor support and magnetic poles disposed on the rotor support, the magnetic poles corresponding to the coil assembly. When the shaftless motor starts, the coil assembly is energized, and the magnetic force between the coil assembly and the magnetic poles causes the motor rotor to rotate at high speed relative to the motor stator. The motor rotor drives the stirring blade assembly to rotate at high speed, thereby achieving the mixing and pulverizing of the food in the mixing cup.

[0006] Furthermore, the stirring blade assembly includes a blade holder and a stirring blade disposed on the blade holder, wherein the blade holder and / or the stirring blade have a magnetic attraction force with the magnetic pole. Thus, the magnetic attraction force between the stirring blade assembly and the magnetic pole prevents the stirring blade assembly from falling off during pouring.

[0007] Furthermore, the blade holder includes a base disposed inside the motor rotor and a gripper protruding upward from the motor rotor, with the mixing blade disposed inside the base. When the shaftless motor starts, the motor rotor drives the mixing blade assembly to rotate at high speed, generating eddies. This causes the food to enter the base and be agitated and pulverized by the mixing blade, avoiding the problem of excessive noise caused by cavitation during high-speed rotation of the mixing blade in conventional food processors, thus resulting in lower noise during operation. In addition, the gripper facilitates the user's installation and removal of the mixing blade assembly.

[0008] Furthermore, the blade holder includes a base body and a handle. The base body is disposed inside the motor rotor, and the stirring blade is held between the base body and the handle, with the stirring blade positioned above the motor rotor. This allows for convenient assembly of the stirring blade onto the blade holder, and facilitates user installation and disassembly of the stirring blade assembly via the handle.

[0009] Furthermore, the rotor support is provided with a first anti-rotation part, and the blade holder is provided with a second anti-rotation part that cooperates with the first anti-rotation part. This ensures that the motor rotor can drive the stirring blade assembly to rotate synchronously, preventing relative rotation between the motor rotor and the stirring blade assembly.

[0010] Furthermore, one of the first and second anti-rotation parts is a raised rib, and the other is a groove that mates with the raised rib; or, one of the first and second anti-rotation parts is a flat part, and the other is a flat groove that mates with the flat part. In both cases, relative rotation between the motor rotor and the stirring blade assembly can be effectively prevented.

[0011] Furthermore, the rotor support includes an annular support sidewall and a support bottom wall disposed at the bottom end of the support sidewall, and the stirring blade assembly is assembled inside the support sidewall. By providing a support bottom wall located at the bottom end of the support sidewall, leakage of liquid from the stirring cup between the motor rotor and the stirring blade assembly can be prevented.

[0012] Furthermore, the food processor includes a base, which includes a housing, a control circuit board, and a lower coupler. The lower coupler is electrically connected to the control circuit board. The mixing cup assembly includes an upper coupler electrically connected to the coil assembly, and the upper coupler is connected to the lower coupler. This achieves electrical connection between the shaftless motor and the control circuit board.

[0013] Furthermore, the chassis has a motor hole, and the shaftless motor is disposed within the motor hole, with a seal formed between the motor stator and the chassis. By placing the shaftless motor within the motor hole, the height of the shaftless motor is reduced, which facilitates the stirring blade assembly in stirring and pulverizing the ingredients at the bottom of the stirring cup, resulting in more thorough pulverization.

[0014] Furthermore, the shaftless motor is assembled on the chassis; or, the stirring cup includes a cup body, a cup base, and a locking seat, with the chassis clamped between the cup body and the locking seat, and the shaftless motor assembled on the locking seat.

[0015] Furthermore, the mixing blade assembly includes a blade holder and mixing blades disposed on the blade holder, the blade holder being assembled with the motor rotor via a detachable structure. Thus, after use of the food processor, the mixing blade assembly can be disassembled for cleaning, resulting in a more thorough cleaning. Attached Figure Description

[0019] This application provides a food processor 100, which can be a soy milk maker, a high-speed blender, a juicer, etc., and is not limited thereto. The food processor 100 includes a blending cup assembly 10, a shaftless motor 20, and a blending blade assembly 30.

[0020] Please see Figures 1 to 6 The mixing cup assembly 10 includes a mixing cup 11, a base 12 disposed at the bottom of the mixing cup 11, and a lid 13 covering the mixing cup 11. The mixing cup 11 is used to hold food ingredients. In the illustrated embodiment, the base 12 may be equipped with a heating element, a temperature sensor, a thermostat, and a fuse, etc. The heating element is used to heat the food ingredients inside the mixing cup 11. In other embodiments, the base 12 may not be equipped with a heating element.

[0021] A shaftless motor 20 is disposed within the stirring cup 11. The shaftless motor 20 includes a motor stator 21 and a motor rotor 22. The motor stator 21 has a through hole 211 extending vertically, and the motor rotor 22 is disposed within the through hole 211. A stirring blade assembly 30 is detachably assembled to the motor rotor 22, and the stirring blade assembly 30 can rotate together with the motor rotor 22.

[0022] Since the blade assembly 30 is detachably assembled to the motor rotor 22, the blade assembly 30 can be disassembled for cleaning after the food processor 100 is used. This makes cleaning more thorough and less likely to hurt your hands. In addition, by setting the shaftless motor 20 inside the mixing cup 11 and driving the blade assembly 30 to rotate through the motor rotor 22, the overall height of the food processor 100 can be effectively reduced, which is conducive to the miniaturization of the food processor 100.

[0023] The motor stator 21 includes a stator support 219 and a coil assembly 218 disposed on the stator support 219. The motor rotor 22 includes a rotor support 221 and magnetic poles 222 disposed on the rotor support 221, with the magnetic poles 222 corresponding to the coil assembly 218. When the shaftless motor 20 starts, the coil assembly 218 is energized, and the magnetic force between the coil assembly 218 and the magnetic poles 222 causes the motor rotor 22 to rotate at high speed relative to the motor stator 21. The motor rotor 22 drives the stirring blade assembly 30 to rotate at high speed, thereby achieving the stirring and pulverizing of the food in the stirring cup 11. In the illustrated embodiment, the magnetic poles 222 are permanent magnets. In other embodiments, the magnetic poles 222 can be made of magnetizable materials such as metallic iron or soft magnetic steel.

[0024] The stator support 219 has a receiving cavity 2191, and the coil assembly 218 is encapsulated within the receiving cavity 2191. Thus, by encapsulating the coil assembly 218 within the receiving cavity 2191, contact between the food slurry and the coil assembly 218 is prevented. The stator support 219 can be made of plastic, but is not limited to this.

[0025] The rotor support 221 has a groove 2219, and the magnetic pole 222 is disposed in the groove 2219. In this way, the magnetic pole 222 and the rotor support 221 are assembled into one unit to form the motor rotor 22.

[0026] A first bearing 229 and a second bearing 228 are provided between the stator support 219 and the rotor support 221, and the first bearing 229 and the second bearing 228 are spaced apart in the vertical direction. In this way, the motor rotor 22 is rotatably mounted inside the motor stator 21, and the structure is stable and reliable.

[0027] The stirring blade assembly 30 includes a blade holder 31 and a stirring blade 32 disposed on the blade holder 31. The blade holder 31 and / or the stirring blade 32 have a magnetic attraction force with the magnetic pole 222. Thus, the magnetic attraction force between the stirring blade assembly 30 and the magnetic pole 222 prevents the stirring blade assembly 30 from falling off during pouring. In some embodiments, the blade holder 31 is made of soft magnetic steel, metallic iron, or a magnetic material.

[0028] The blade holder 31 includes a base 311 disposed inside the motor rotor 22 and a gripper 312 protruding upward from the motor rotor 22. The mixing blade 32 is disposed inside the base 311. When the shaftless motor 20 starts, the motor rotor 22 drives the mixing blade assembly 30 to rotate at high speed, generating eddies. This causes the food to enter the base 311 and be agitated and pulverized by the mixing blade 32. This avoids the problem of excessive noise caused by cavitation generated by the high-speed rotation of the mixing blade in conventional food processors, thus making the food processor 100 quieter during operation. In addition, the gripper 312 facilitates the user's installation, disassembly, and other operations of the mixing blade assembly 30.

[0029] In the illustrated embodiment, the stirring blade 32 is inclined and positioned inside the base 311, which helps to improve the efficiency of pulverizing food ingredients. The stirring blade 32 can be fixed to the inside of the base 311 by welding, fasteners, or other means. The stirring blade 32 can be configured as one blade, two blades, or multiple blades.

[0030] Please see Figures 7 to 10 The blade holder 31 includes a base body 313 and a handle 314. The base body 313 is disposed inside the motor rotor 22, and the stirring blade 32 is held between the base body 313 and the handle 314, with the stirring blade 32 positioned above the motor rotor 22. This allows for easy assembly of the stirring blade 32 onto the blade holder 31, and facilitates user installation and removal of the stirring blade assembly 30 via the handle 314. In the illustrated embodiment, the base body 313 and the handle 314 are fixed together by a threaded structure.

[0031] The rotor support 221 is provided with a first anti-rotation part 2211, and the blade holder 31 is provided with a second anti-rotation part 315 that cooperates with the first anti-rotation part 2211. In this way, it is ensured that the motor rotor 22 can drive the stirring blade assembly 30 to rotate synchronously, and relative rotation between the motor rotor 22 and the stirring blade assembly 30 is avoided.

[0032] In one embodiment, one of the first anti-rotation part 2211 and the second anti-rotation part 315 is a raised rib, and the other is a groove that mates with the raised rib. In another embodiment, one of the first anti-rotation part 2211 and the second anti-rotation part 315 is a flat part, and the other is a flat groove that mates with the flat part. In this way, relative rotation between the motor rotor 22 and the stirring blade assembly 30 can be effectively avoided.

[0033] In the illustrated embodiment, the rotor support 221 includes an annular support sidewall 2213 and a support bottom wall 2214 disposed at the bottom end of the support sidewall 2213, and the stirring blade assembly 30 is assembled inside the support sidewall 2213. By providing the support bottom wall 2214 located at the bottom end of the support sidewall 2213, leakage of liquid in the stirring cup 11 from between the motor rotor 22 and the stirring blade assembly 30 can be prevented.

[0034] In the illustrated embodiment, the food processor 100 includes a base 40, which includes a housing 41, a control circuit board, and a lower coupler 42. The lower coupler 42 is electrically connected to the control circuit board. The blending cup assembly 10 includes an upper coupler 14 electrically connected to the coil assembly 218, and the upper coupler 14 is mated with the lower coupler 42. This achieves electrical connection between the shaftless motor 20 and the control circuit board. In another embodiment, the food processor 100 does not include a base, and the control circuit board is directly mounted on the blending cup assembly 10.

[0035] In the illustrated embodiment, the chassis 12 is provided with a motor hole 121, and the shaftless motor 20 is disposed within the motor hole 121, with the motor stator 21 forming a seal with the chassis 12. By disposing of the shaftless motor 20 within the motor hole 121, the height of the shaftless motor 20 is reduced, which facilitates the stirring blade assembly 30 in stirring and pulverizing the ingredients at the bottom of the stirring cup 11, resulting in more thorough pulverization.

[0036] In another embodiment, the chassis 12 may not have a motor hole, but instead has a downward-facing recess in the chassis 12, within which the shaftless motor 20 is disposed. In yet another embodiment, the chassis 12 does not have a motor hole or recess, and the shaftless motor 20 is directly disposed on the chassis 12.

[0037] In one embodiment, the shaftless motor 20 is assembled on the chassis 12. Specifically, the motor stator 21 is provided with a mounting part, and the shaftless motor 20 is fixed to the chassis 12 by fasteners passing through the mounting part and locking it with the chassis 12. Of course, the shaftless motor 20 can also be fixed to the chassis 12 in other ways, and is not limited to this.

[0038] In another embodiment, the stirring cup 11 includes a cup body 111, a cup base 112, and a locking seat 113. The base 12 is clamped between the cup body 111 and the locking seat 113, and the shaftless motor 20 is assembled to the locking seat 113. The shaftless motor 20 and the locking seat 113 can be fixed together by fasteners or other means. A disc sealing ring 114 is provided between the base 12 and the cup body 111. During assembly, the shaftless motor 20 and the locking seat 113 are first assembled together, and then the two are assembled together as a whole with the cup body 111 by screw fasteners, while the base 12 is clamped and fixed at the same time.

[0039] The mixing blade assembly 30 includes a blade holder 31 and a mixing blade 32 disposed on the blade holder 31. The blade holder 31 is assembled with the motor rotor 22 via a detachable structure. Thus, after use of the food processor 100, the mixing blade assembly 30 can be disassembled for cleaning, resulting in a more thorough cleaning. In one embodiment, the "detachable structure" can be a snap-fit ​​structure, but it is not limited to this.

[0040] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
