Description

Technical Field

[0001] This application relates to the field of small household appliance technology, and more specifically, to a blending cup assembly and 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. Direct-drive food processors include a mixing jar assembly and a lid assembly covering the mixing jar assembly. The mixing jar assembly includes a mixing jar and a motor located at the bottom of the mixing jar. The mixing blade is located on the output shaft of the motor. However, existing motors are fixed to the motor bracket by outward-extending mounting feet, which results in a large motor installation space and thus a large overall size of the food processor, which is not conducive to weight reduction and cost reduction. Utility Model Content

[0003] This application provides a mixing cup assembly and a food processor that can reduce the installation space of the motor, thereby reducing the overall size of the food processor, which is beneficial for achieving lightweighting and cost reduction.

[0004] This application provides a mixing cup assembly, comprising: a mixing cup; and a motor assembly, including a motor mounting bracket, a motor, and a motor limiting member. The motor mounting bracket is disposed at the bottom end of the mixing cup and has a receiving space. The motor is housed within the receiving space. The motor limiting member is fixed to the motor mounting bracket and cooperates with the motor to confine the motor within the receiving space. The motor shaft extends into the mixing cup, and a mixing blade is provided at the top end of the motor shaft. By confining the motor within the receiving space of the motor mounting bracket using the motor limiting member, the motor does not need to have outwardly protruding mounting feet to be fixed within the motor mounting bracket, which reduces the installation space of the motor and thus reduces the overall size of the food processor, contributing to weight reduction and cost reduction. In addition, by placing the motor within the receiving space of the motor mounting bracket, the motor can maintain better stability during operation, which is beneficial for vibration reduction.

[0005] Furthermore, the motor mounting bracket includes a first frame that is fixed to the mixing cup and a second frame connected to the first frame, with the receiving space disposed in the second frame. By fixing the first frame to the mixing cup and the second frame to fix the motor, the motor is assembled at the bottom of the mixing cup, allowing the motor to directly drive the stirring blade to rotate. This design is simple in structure and easy to assemble.

[0006] Furthermore, the second frame is provided with a limiting part, and the motor is clamped and fixed by the limiting part and the motor limiting member. By clamping and fixing the motor with the limiting part and the motor limiting member, the motor can be positioned more stably, which is more conducive to the motor maintaining stability during the operation of the food processor.

[0007] Furthermore, the second frame is provided with a limiting rib that presses against the motor radially. By having the limiting rib press against the motor radially, the positioning of the motor is more stable and reliable, and it is less likely to shake during operation.

[0008] Furthermore, the motor includes a motor rotor fixed to the motor shaft and a motor stator disposed outside the motor rotor, with the motor limiting member pressing against the motor stator. By pressing the motor limiting member against the motor stator, the motor can be confined within the receiving space.

[0009] Furthermore, the motor includes a motor rotor fixed to the motor shaft and a motor stator disposed outside the motor rotor. The motor stator includes a stator core and coil windings, and the motor limiting member is integrally formed with the stator core. Thus, by fixing the motor limiting member to the motor mounting bracket, the motor can be confined within the receiving space.

[0010] Furthermore, the stirring cup includes a cup body and a base plate disposed at the bottom of the cup body. The motor mounting bracket and the cup body are assembled together by a snap-fit ​​structure. The base plate is clamped between the motor mounting bracket and the cup body, and the motor shaft passes through the base plate. In this way, while assembling the motor mounting bracket at the bottom of the cup body, the base plate is clamped and fixed by the cooperation between the motor mounting bracket and the cup body.

[0011] Furthermore, the motor limiting component is fixed to the motor mounting bracket by fasteners. This allows for convenient and reliable fixing of the motor limiting component to the motor mounting bracket.

[0012] Furthermore, the stirring cup assembly includes a cup base and a high-voltage coupler and a low-voltage coupler fixed to the motor mounting bracket. The cup base has coupler holes corresponding to the high-voltage coupler and the low-voltage coupler, respectively. By setting the couplers as high-voltage and low-voltage couplers, the size of the high-voltage and low-voltage couplers is reduced, so that the space between the motor mounting bracket and the cup base is sufficient to accommodate the high-voltage and low-voltage couplers. This allows the high-voltage and low-voltage couplers to at least partially overlap with the motor in the height direction, thus helping to reduce the height of the stirring cup assembly.

[0013] Furthermore, the motor is a brushless motor, comprising a shaft frame, a motor rotor, and a motor stator. The shaft frame is connected to the motor stator, the motor shaft is fixed to the motor rotor, and the motor shaft is rotatably supported by the shaft frame. The motor stator is located on the outside of the motor rotor. This design facilitates a thinner and lighter motor, thereby reducing the overall height and weight of the food processor.

[0014] This application provides a food processor, which includes: a base; and a mixing cup assembly as described above, assembled on the base. Attached Figure Description

Detailed Implementation

[0016] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0017] Please see Figures 1 to 5 The food processor 100 of this application includes a base 60, a blending cup assembly 50, and a lid assembly 40. The blending cup assembly 50 is assembled on the base 60, and the lid assembly 40 covers the blending cup assembly 50. The base 60 includes a housing and a control circuit board disposed within the housing.

[0018] The mixing cup assembly 50 includes a mixing cup 10 and a motor assembly 20. The motor assembly 20 includes a motor mounting bracket 21, a motor 22, and a motor limiting member 23. The motor mounting bracket 21 is disposed at the bottom end of the mixing cup 10 and has a receiving space 211. The motor 22 is accommodated within the receiving space 211. The motor limiting member 23 is fixed to the motor mounting bracket 21 and cooperates with the motor 22 to confine the motor 22 within the receiving space 211. The motor shaft 220 of the motor 22 extends into the mixing cup 10, and a stirring blade 24 is provided at the top end of the motor shaft 220. In the illustrated embodiment, the mixing cup 10 is provided with a handle 19, which includes a handle body 191 and a handle cover 192.

[0019] The mixing cup assembly 50 of this application uses a motor limiting member 23 to confine the motor 22 within the receiving space 211 of the motor mounting bracket 21. In other words, the motor 22 does not need to be provided with outwardly protruding mounting feet to be fixed in the motor mounting bracket 21, which can reduce the installation space of the motor 22 and thus reduce the overall size of the food processor 100, which is conducive to achieving weight reduction and cost reduction. In addition, by placing the motor 22 within the receiving space 211 of the motor mounting bracket 21, the motor 22 can maintain better stability during operation, which is beneficial for vibration reduction.

[0020] The motor mounting bracket 21 includes a first bracket 212 that is fixed to the stirring cup 10 and a second bracket 213 connected to the first bracket 212. The receiving space 211 is disposed in the second bracket 213. By fixing the first bracket 212 to the stirring cup 10 and fixing the motor 22 to the second bracket 213, the motor 22 is assembled at the bottom of the stirring cup 10, allowing the motor 22 to directly drive the stirring blade 24 to rotate. The structure is simple and easy to assemble.

[0021] The second frame 213 is also provided with a limiting part 2131, and the motor 22 is clamped and fixed by the limiting part 2131 and the motor limiting member 23. By clamping and fixing the motor 22 with the limiting part 2131 and the motor limiting member 23, the motor 22 can be positioned more stably, thus making it easier for the motor 22 to remain stable during the operation of the food processor 100. The limiting part 2131 is located at the top of the second frame 213 and is ring-shaped.

[0022] The second frame 213 is provided with a limiting rib 2132 that presses against the motor 22 radially. The limiting rib 2132 pressing against the motor 22 radially makes the positioning of the motor 22 more stable and reliable, and less prone to shaking during operation. The number of limiting ribs 2132 can be 1, 2, 3, 4, 5, 6, 7, or 8, and is not limited to these.

[0023] In the illustrated embodiment, the motor 22 includes a motor rotor 221 fixed to the motor shaft 220 and a motor stator 222 disposed outside the motor rotor 221, with the motor limiting member 23 pressing upward against the motor stator 222. By pressing the motor limiting member 23 upward against the motor stator 222, the motor 22 can be confined within the receiving space 211.

[0024] Please see Figure 6 The motor 22 includes a motor rotor 221 fixed to the motor shaft 220 and a motor stator 222 disposed outside the motor rotor 221. The motor stator 222 includes a stator core and coil windings. The motor limiting member 23 is integrally formed with the stator core. Thus, by fixing the motor limiting member 23 to the motor mounting bracket 21, the motor 22 can be confined within the receiving space 211.

[0025] In the illustrated embodiment, the stirring cup 10 includes a cup body 11 and a base 12 disposed at the bottom of the cup body 11. The motor mounting bracket 21 and the cup body 11 are assembled together by a snap-fit ​​structure. The base 12 is clamped between the motor mounting bracket 21 and the cup body 11, and the motor shaft 220 passes through the base 12. Thus, while assembling the motor mounting bracket 21 at the bottom of the cup body 11, the base 12 is clamped and fixed by the cooperation of the motor mounting bracket 21 and the cup body 11. In another embodiment, the motor mounting bracket 21 and the cup body 11 are assembled together by a threaded structure. A disc sealing ring 129 is provided between the base 12 and the cup body 11. A bracket sealing ring 218 is provided between the motor mounting bracket 21 and the cup body 11.

[0026] The motor limiting member 23 is fixed to the motor mounting bracket 21 by fasteners 231. In this way, the motor limiting member 23 can be conveniently and reliably fixed to the motor mounting bracket 21. Specifically, the motor mounting bracket 21 includes a plurality of studs 219, and the motor limiting member 23 is provided with a plurality of through holes 239. The plurality of fasteners 231 (screws) pass through the through holes 239 and are locked with the studs 219.

[0027] In the illustrated embodiment, the motor mounting bracket 21 includes three studs 219, and the motor limiting member 23 has three corresponding through holes 239. Three fasteners 231 pass through the through holes 239 and are locked to the studs 219. These are just some examples and are not limited to the above examples. In other embodiments, the motor limiting member 23 can also be fixed to the motor mounting bracket 21 in other ways.

[0028] The stirring cup assembly 50 includes a cup holder 33 and a high-voltage coupler 31 and a low-voltage coupler 32 fixed to the motor mounting bracket 21. The cup holder 33 has coupler holes 331 corresponding to the high-voltage coupler 31 and the low-voltage coupler 32, respectively. By setting the couplers as high-voltage couplers 31 and low-voltage couplers 32, the size of the high-voltage couplers 31 and low-voltage couplers 32 is reduced, so that the space between the motor mounting bracket 21 and the cup holder 33 is sufficient to accommodate the high-voltage couplers 31 and low-voltage couplers 32. This allows the high-voltage couplers 31 and low-voltage couplers 32 to at least partially overlap with the motor in the height direction, thus helping to reduce the height of the stirring cup assembly 50.

[0029] The motor 22 is a brushless motor, comprising a shaft frame 224, a motor rotor 221, and a motor stator 222. The shaft frame 224 is connected to the motor stator 222. The motor shaft 220 is fixed to the motor rotor 221 and rotatably supported by the shaft frame 224. The motor stator 222 is located on the outside of the motor rotor 221. This design facilitates a thinner and lighter motor, thereby reducing the overall height and weight of the food processor 100.

[0030] 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.
