Description

Technical Field

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

[0002] As people's living standards continue to improve, many different types of food processors have appeared on the market. Food processors generally use traditional motors, which are assembled with the container body through components such as upper and lower supports, and drive the blades through the motor shaft. However, traditional motors are too tall, resulting in an excessively tall container body that affects the appearance. Furthermore, traditional motors have many parts and are bulky, making the container body too heavy, inconvenient for consumers to clean, and resulting in a poor overall user experience.

[0003] Therefore, it is necessary to design a food processor that solves the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this application is to provide a food processor that can reduce the height of the motor assembly.

[0005] This application provides a food processor, including:

[0006] A mixing cup, comprising a cup body and a cup base disposed at the bottom of the cup body; and

[0007] The stirring head module includes a blade assembly, a blade disc assembly, a motor assembly, and a locking seat. The motor assembly includes a stator assembly and a rotor assembly rotatably disposed within the stator assembly. The stator assembly is mounted on the locking seat or the blade disc assembly. The output end of the rotor assembly is mounted on the blade disc assembly and extends into the cup body to connect with the blade assembly. The locking seat is fixed to the bottom of the cup holder. By eliminating the upper and lower supports of the motor assembly, mounting the stator assembly on the locking seat or the blade disc assembly, and mounting the rotor assembly on the blade disc assembly, the height of the motor assembly can be reduced, further reducing the height of the cup holder.

[0008] Furthermore, the stator assembly includes a stator support, a wire frame, and a sealing cover; the stator support has an inner wall and an outer wall; the inner wall forms an annular through groove, and the inner wall and the outer wall form an annular groove, with the wire frame sealed within the annular groove by the sealing cover. Thus, by employing the annular groove design, the sealing performance and stability of the stator assembly are effectively improved. The annular through groove design can accommodate the rotor assembly, allowing the rotor assembly to interact with the stator assembly, and the resulting rotational force drives the rotor assembly to rotate.

[0009] Furthermore, the outer wall edge is provided with a plurality of spaced mounting brackets along its circumferential direction, and the mounting brackets are fixed to the locking seat or the cutter head assembly. Thus, the mounting brackets eliminate the need for the lower bracket to fix the stator assembly. In addition, distributing the mounting brackets along the edge of the outer wall reduces the height of the stator bracket, further reducing the height of the stator assembly.

[0010] Furthermore, the rotor assembly includes a centrally located shaft, a rotor core disposed at one end of the shaft, and magnets disposed outside the rotor core; a downward-opening cavity is formed within the rotor core. Thus, the rotor core forms a hollow cavity, which can accommodate other components, effectively saving space in the vertical direction.

[0011] Furthermore, the blade assembly has a through hole, and the middle part of the rotating shaft is fixed in the through hole by a bearing. The other end of the rotating shaft is connected to the blade assembly. This eliminates the need for the upper bracket to fix the rotor assembly. In addition, the rotational force on the rotating shaft drives the blade assembly to rotate and cut the food.

[0012] Furthermore, the stirring head module also includes an upper coupler, which is partially placed inside the cavity and fixed to the cup seat or the locking seat. In this way, the upper coupler is accommodated within the hollow cavity formed by the rotor core, reducing the space occupied by the upper coupler in the vertical direction.

[0013] Furthermore, the upper coupler is circular and positioned in the center of the stirring head module. This circular upper coupler allows the stirring cup to rotate 360 ​​degrees without requiring alignment during placement. Additionally, placing the upper coupler in the center of the stirring head module allows for a more compact overall structure and reduced height.

[0014] Furthermore, it also includes a host component, which comprises a housing and a light guide plate, a control board, and a lower coupler disposed within the housing; the lower coupler is coupled to the upper coupler and electrically connected to the control board. In this way, integrating multiple functional modules (such as the light guide plate, control board, and lower coupler) within the host component allows multiple independent parts to be integrated into a compact system, reducing space occupation and improving the compactness and integration of the host component.

[0015] Furthermore, it also includes a main unit assembly, which comprises a power supply assembly and a control panel. The power supply assembly is electrically connected to the control panel and the motor assembly, and the control panel is mounted on the outer wall of the blending cup. This eliminates the need for an external main unit assembly, making the blender smaller and lighter.

[0016] Furthermore, the height of the cup base is 30mm-80mm; the height of the stator assembly is greater than 25mm and less than 60mm. Thus, the motor assembly is compact and lightweight, reducing the overall height of the cooking cup by 50%-70% compared to existing technologies, and reducing the overall weight of the cooking cup by 30%.

[0017] This application has the following beneficial effects: by eliminating the upper and lower supports of the motor assembly, mounting the stator assembly in the motor assembly on the locking seat or the cutter head assembly, and mounting the rotor assembly on the cutter head assembly, the height of the motor assembly can be reduced, and the height of the cup holder can be further reduced.

[0032] Reference Figure 1 , Figure 2 and Figure 4 As shown, this application discloses a food processor, which includes a blending cup 10, a blending head module 20, and a main unit assembly 30. The blending head module 20 is electrically connected to the main unit assembly 30, and the main unit assembly 30 is used to drive the blending head module 20 to cut food within the blending cup 10.

[0033] The mixing cup 10 includes a cup body 11, a cup base 12 disposed at the bottom of the cup body 11, a handle 14 disposed on the side of the cup body 11, and a cup lid 16 disposed on the top of the cup body 11. The cup body 11 and the cup base 12 are sealed by a cup base sealing ring 121 to prevent external substances from entering the cup base 12 and affecting the normal operation of the main unit 30.

[0034] In this embodiment, a shock-absorbing pad 13 is provided between the handle 14 and the cup body 11. Furthermore, a handle cover 15 is installed on the handle 14. The handle cover 15 can be made of a soft material such as silicone to increase the user's grip comfort. Additionally, a control panel can be integrated into the handle cover 15 to improve the ease of user operation.

[0035] Please continue to refer to the reference. Figure 3 and Figures 7-11 As shown, the stirring head module 20 includes a blade assembly 21, a blade disc assembly 22, a motor assembly 23, a locking seat 24, and an upper coupler 25. The locking seat 24 is fixed to the bottom of the cup holder 12.

[0036] The cutter disc assembly 22 is sealed to the cup body 11 and the locking seat 24 by a cutter disc sealing ring 222 to prevent liquid in the cup body 11 from flowing into the stirring head module 20, thereby affecting the normal operation of the main unit 30. The cutter disc assembly 22 is provided with a through hole 221, which is arranged in the middle of the cutter disc assembly 22.

[0037] A temperature sensing element 26 is provided on the top of the blade assembly 22. The temperature sensing element 26 measures the surface temperature of the blade assembly 22 in real time to prevent the food from burning due to a large temperature difference between the heating element of the food processor and the surface of the blade assembly 22.

[0038] The temperature sensing element 26 can be a thermistor, an infrared detector, or a thermocouple. This improves the accuracy of temperature measurement and ensures precise temperature control during cooking. Thermistors are low-cost. Infrared detectors enable non-contact temperature measurement, avoiding potential contamination or damage from direct contact. Thermocouples offer excellent durability in extreme environments and are suitable for long-term stable use.

[0039] The motor assembly 23 includes a stator assembly 231 and a rotor assembly 232 rotatably disposed within the stator assembly 231. The output end of the rotor assembly 232 is mounted on the cutter head assembly 22 and extends into the cup body 11 through a through hole 221 to connect with the cutter assembly 21. The stator assembly 231 is mounted on the locking seat 24 or the cutter head assembly 22.

[0040] The structure of the motor assembly 23 eliminates the upper and lower supports, and by mounting the stator assembly 231 of the motor assembly 23 on the locking seat 24 or the cutter head assembly 22, and mounting the rotor assembly 232 on the cutter head assembly 22, the height of the motor assembly 23 can be reduced. This further reduces the height of the cup holder 12.

[0041] The stator assembly 231 is composed of coil windings. When energized, these coil windings generate a magnetic field when current flows through them. The rotor assembly 232 has a permanent magnet 2323 attached to it. The permanent magnet 2323 interacts with the magnetic field to generate a rotational force that drives the rotor assembly 232 to rotate. Then, the rotor assembly 232 drives the blade assembly 21 to rotate and cut the food inside the cup body 11.

[0042] Specifically, the stator assembly 231 includes a stator support 2311, a wire frame 2312, and a sealing cover 2313. The stator support 2311 has an inner wall 2314 and an outer wall 2315, with the inner wall 2314 forming an annular through groove 2316. The annular through groove 2316 is designed to accommodate the rotor assembly 232, allowing the rotor assembly 232 to interact with the stator assembly 231, and the resulting rotational force drives the rotor assembly 232 to rotate.

[0043] An annular groove 2317 with an upward opening is formed between the inner wall 2314 and the outer wall 2315, and the wire frame 2312 is sealed in the annular groove 2317 by a sealing cover 2313. The design of the annular groove 2317 effectively improves the sealing performance and stability of the stator assembly 231. The annular groove 2317 and the annular through groove 2316 are arranged coaxially.

[0044] In this application, the bottom edge of the outer wall 2315 is provided with a plurality of spaced mounting brackets 2318 along the circumferential direction. The mounting brackets 2318 are fixed to the bottom of the locking seat 24, and the stator assembly 231 is accommodated in the cavity of the locking seat 24. In another embodiment, the top edge of the outer wall 2315 is provided with a plurality of spaced mounting brackets 2318 along the circumferential direction, and the mounting brackets 2318 are fixed to the bottom of the cutter head assembly 22.

[0045] The two embodiments described above eliminate the need for the lower bracket to fix the stator assembly 231 through the design of the mounting bracket 2318. Furthermore, distributing the mounting bracket 2318 along the edge of the outer wall 2315 does not require increasing the height of the stator assembly 231. Therefore, while fixing the stator assembly 231, the height of the stator support 2311 can be reduced, further reducing the height of the stator assembly 231.

[0046] The rotor assembly 232 includes a centrally located shaft 2321, a rotor core 2322 disposed at one end of the shaft 2321, and a magnet 2323 disposed outside the rotor core 2322. A downward-opening cavity 2324 is formed inside the rotor core 2322.

[0047] The middle part of the rotating shaft 2321 is fixed in the through hole 221 by the bearing 2328A, and the other end of the rotating shaft 2321 is connected to the cutter assembly 21. In this embodiment, the rotating shaft 2321 is fixed in the cutter assembly 22 by first installing the oil seal 2325 into the cutter assembly 22, then the rotating shaft 2321 is clamped in the E-shaped retaining ring 2326A, then the bearing 2328A is installed, then the bearing 2328A is partially installed into the cutter assembly 22, and finally the bearing 2328A is fixed in place by the inner retainer 2327A.

[0048] Next, the rotor core 2322 and magnet 2323 are fixed, then the rotor core 2322 is passed through the rotating shaft 2321, then the bearing 2328B is fixed, and finally the E-shaped retaining ring 2326B and inner retainer 2327B are installed, thus completing the fixing of the rotor core 2322 and magnet 2323 at the end of the rotor assembly 232. Finally, the knife assembly 21 is installed inside the cup body 11.

[0049] The upper coupler 25 is partially placed inside the cavity 2324 and is fixed to the cup holder 12 or the locking seat 24, for example, by means of a clip or screw. In this way, the upper coupler 25 is accommodated in the hollow cavity 2324 formed by the rotor core 2322, reducing the space occupied by the upper coupler 25 in the vertical direction.

[0050] The upper coupler 25 is circular, allowing the stirring cup 10 to rotate 360 ​​degrees without requiring alignment during placement. Furthermore, placing the upper coupler 25 in the center of the stirring head module 20 allows for a more compact overall structure and reduces height. In some cases, the upper coupler 25 is square.

[0051] Please continue to refer to the reference. Figure 5 As shown, the host component 30 includes a housing 31 and a light guide plate 32, a control plate 33, a lower coupler 34, and a buffer pad (not shown in the figure) placed inside the housing 31.

[0052] The housing 31 includes a base 312 and a top cover 311, which are connected by a snap-fit ​​mechanism, facilitating the disassembly and maintenance of the main unit 30. A cushioning pad is provided on the surface of the top cover 311, which serves to position and absorb shock when the mixing cup is installed on the main unit. The cushioning pad can be made of a soft material such as silicone.

[0053] The light guide plate 32 is used to guide the light of the control plate 33. The lower coupler 34 is coupled to the upper coupler 25 and electrically connected to the control plate 33 to realize the functions of heating and stirring of the food processor.

[0054] In another embodiment, refer to Figure 12As shown, the main unit 30 includes a power supply unit 35 and an operation panel (not shown). The power supply unit 35 is electrically connected to the operation panel and the motor assembly 23. The power supply unit 35 is a separate power interface. In some cases, the power supply unit may also be powered by a direct power cord or a built-in battery.

[0055] The control panel is placed on the outer wall of the blending cup 10, such as on the outer wall of the cup body 11, the outer wall of the cup base 12, or the outer wall of the handle cover 15. In this way, the external main unit 30 is eliminated, making the food processor smaller and lighter.

[0056] Compared to the existing cup holder 12, which has a height greater than 100mm, in this application, referring to Figure 6 As shown, the height 'a' of the cup holder 12 is 30mm-80mm. For example, the height of the cup holder 12 can be 30mm, 45mm, 50mm, 70mm, or 80mm. The height of the cup holder 12 depends on the height of the stirring head module 20 arranged within the cup holder 12, such as the height of the motor assembly 23. This application reduces the height of the cup holder 12 by lowering the height of the motor assembly 23, thereby reducing the overall height of the blending cup by 50%-70% compared to existing heights. Simultaneously, by reducing the number of parts in the motor assembly 23, the weight of the entire blending cup is reduced by 30%.

[0057] Furthermore, the height of the motor assembly 23 depends on the heights of the stator assembly 231 and the rotor assembly 232. In this application, the height b of the stator assembly 231 is greater than 25mm and less than 60mm; for example, the height of the stator assembly 231 can be 26mm, 30mm, 45mm, 55mm, or 59mm. This satisfies both the requirements for a compact and lightweight motor assembly 23 and its performance requirements.

[0058] 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.
