Technical Field

[0001] This utility model relates to the field of food processor technology, and in particular to a control structure, a drive module, and a food processor. Background Technology

[0002] The main functions of food processors on the market today include making soy milk, grinding dry powders, juicing, mincing meat, shaved ice, making coffee, and even preparing beauty masks for women. A food processor consists of a base and a cup assembly. The cup assembly contains blades for grinding food, while the base typically houses the motor, cooling fan, and control panel. When the cup assembly is installed on the base, the motor and blades are connected, and the cooling fan dissipates heat from the motor and control panel.

[0003] In existing technology, the control panel is located on the side of the base, with the drive motor and cooling fan coaxially arranged. The cooling fan drives airflow to dissipate heat from both the drive motor and the control panel. However, because the air inlet at the location of the control panel is relatively small, it cannot achieve large-area heat dissipation for the control panel, thus affecting its lifespan.

Detailed Implementation

[0032] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0033] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings.

[0036] Please see Figures 1 to 7 The control structure 100 provided in the first embodiment of this utility model includes a mounting cover 10, a control panel 20, and a cooling fan 30.

[0037] Please refer to Figures 1 to 3 The mounting cover 10 has a mounting cavity 15 as a mounting base; the control panel 20 is located in the mounting cavity 15 of the mounting cover 10 and is used to control the start and stop of the drive mechanism, including the PCB board and electronic components on the PCB board; the cooling fan 30 is located in the mounting cavity 15 of the mounting cover 10 and is coaxially arranged with the control panel 20. The cooling fan 30 is used to drive airflow into the mounting cover 10 to dissipate heat from the control panel 20.

[0038] The aforementioned control structure 100, by setting up a mounting cover 10, achieves the convergence and flow of air. By setting the cooling fan 30 and the control panel 20 coaxially, the two can be stacked, and the mounting cover 10 can be miniaturized. When the cooling fan 30 rotates, it can drive the airflow into the mounting cover 10, thereby achieving a large contact area of ​​airflow with the control panel 20, realizing rapid heat dissipation of the control panel 20, and ensuring the service life of the control panel 20.

[0039] It should be noted that the control panel 20 in this embodiment is used to control the start and stop of the drive mechanism. When the control structure 100 is applied to a food processor, for example... Figures 4 to 7 The drive motor 210 is used to control the start and stop of the drive motor 210. Understandably, the food processor includes a grinding blade, and the drive motor 210 drives the grinding blade located above itself. Simultaneously, the drive motor 210 drives the cooling fan 30. When the drive motor 210 is installed, the drive motor 210, control panel 20, and cooling fan 30 can be stacked in sequence, so that the airflow can not only cool the control panel 20, but also cool the drive motor 210.

[0040] Specifically, please refer to Figure 1 , Figure 2 as well as Figures 4 to 7During installation, the control panel 20 is positioned above the cooling fan 30. The mounting cover 10 has an upper air inlet 11 and a lower air outlet 12. The cooling fan 30 drives airflow from the upper air inlet 11 to the lower air outlet 12, and the airflow exits through the lower air outlet 12, thereby achieving heat dissipation for the drive motor 210 and the control panel 20. Alternatively, in another embodiment, when the control structure 100 is applied to other electrical equipment, it can be installed with the control panel 20, cooling fan 30, and drive motor 210 arranged from top to bottom. The cooling fan 30 can also be driven to rotate by the drive motor 210, and airflow can also flow over the surfaces of the control panel 20 and the drive motor 210, achieving the effect of heat dissipation.

[0041] When the control structure 100 is applied in a food processor, when the airflow flows along the outer wall of the mounting cover 10 into the mounting cover 10, the mounting cover 10 drives the control panel 20 and the cooling fan 30 to be installed in a housing. An airflow channel is formed between the housing and the mounting cover 10. When the cooling fan 30 rotates, the airflow flows from bottom to top through the airflow channel, then flows in through the upper air inlet 11 of the mounting cover 10, flows in the mounting cover 10 and then flows out through the lower air outlet 12, passing over the surface of the control panel 20, thereby achieving heat dissipation for the control panel 20.

[0042] In one embodiment of this utility model, when installing the control panel 20, a mounting post can be provided on the housing of the drive motor 210, and a mounting hole can be provided on the control panel 20. The mounting hole is connected to the mounting post by bolts, thereby realizing the installation of the control panel 20.

[0043] Please see Figure 1 and Figure 2 In one embodiment of this utility model, corresponding to the installation method of the control panel 20 and the cooling fan 30, the mounting cover 10 includes two parts, namely, an upper mounting part 13 and a lower mounting part 14 from top to bottom. The inner diameter of the upper mounting part 13 is larger than the inner diameter of the lower mounting part 14. The control panel 20 is disposed on the upper mounting part 13, and the cooling fan 30 is disposed on the lower mounting part 14. Thus, by setting two parts with different inner diameters, corresponding to the respective sizes of the control panel 20 and the cooling fan 30, the airflow flows downwards towards the smaller size, creating a gathering effect and achieving the outflow after gathering. At the same time, the larger inner diameter of the upper mounting part 13 can accommodate the larger control panel 20, and the larger area of ​​the control panel 20 can have a larger contact area with the airflow, increasing the heat dissipation efficiency.

[0044] Furthermore, since the control panel 20 and the cooling fan 30 are coaxially arranged, that is, the shaft 40 of the drive motor 210 passes through the control panel 20 and is connected to the cooling fan 30, the drive motor 210 drives the cooling fan 30 to rotate during operation. In order to avoid the drive of the control panel 20 to rotate, the control panel 20 is provided with a clearance opening 21 for the shaft 40 of the drive fan 30 to pass through. The distance between the side wall of the clearance opening 21 and the shaft 40 is 2cm-5cm. That is, a large clearance opening 21 is provided in the middle of the control panel 20. This not only allows the shaft 40 to pass through the clearance opening 21 to connect with the cooling fan 30, but also helps the airflow to flow through the clearance opening 21, which helps the airflow to carry away the heat on the surface of the control panel 20.

[0045] The distance between the side wall of the clearance opening 21 and the pivot 40 can be set to a value of 2cm, 3cm, 4cm or 5cm, etc., and is not limited here.

[0046] Further, please refer to Figure 1 When installing the control panel 20, it is fitted with the inner wall of the mounting cover 10 with a gap. This gap facilitates the installation of the control panel 20 within the mounting cover 10 and reduces installation difficulty. For example, when the two are fitted with a gap, the gap range is set to 0-0.3mm. For instance, the gap can be 0, 0.1mm, 0.2mm, 0.3mm, etc., to avoid the gap being too large, which would prevent airflow from being insufficient to the surface of the control panel 20 and thus reduce its heat dissipation effect.

[0047] Furthermore, when the inner wall gap between the control panel 20 and the mounting cover 10 is set, in order to ensure the efficiency of airflow flowing to the lower part of the mounting cover 10, the control panel 20 is provided with an airflow port 22 for airflow. Thus, through the setting of the airflow port 22, when the airflow flows over the control panel 20, it can flow downwards from the control panel 20, reducing wind resistance and improving the efficiency of airflow, so as to remove the heat generated on the control panel 20.

[0048] Specifically, in this embodiment, the flow port 22 extends to the edge of the control panel 20, thereby facilitating the setting of the flow port 22 on the control panel 20. Compared with the method of opening the flow port 22 in the middle area of ​​the control panel 20, the difficulty of opening the flow port 22 is reduced.

[0049] Understandably, in order to ensure the downward flow of air, the control panel 20 is provided with multiple airflow ports 22. The multiple airflow ports 22 are arranged circumferentially around the rotation axis of the cooling fan 30 on the control panel 20, so that the control panel 20 can be provided with airflow ports 22 at various positions near the mounting cover 10, so that airflow can flow downward from various areas of the control panel 20 and ensure the heat dissipation effect of the control panel 20.

[0050] The control panel 20 includes a circuit board and electronic components mounted on the circuit board. The circuit board has the aforementioned clearance opening 21 and flow opening 22. The electronic components include structures such as heat sink fins. It is understood that since the upper surface of the circuit board is close to the drive motor 210, and the drive motor 210 generates heat, when the electronic components are mounted on the circuit board, they are mounted on the side of the cooling fan 30, that is, on the lower surface of the circuit board, to reduce the transfer of heat generated by the drive motor 210 during operation to the electronic components and ensure the service life of the electronic components.

[0051] The aforementioned control structure 100, by coaxially arranging the control panel 20 and the cooling fan 30, allows the airflow to flow directly and in large quantities onto the surface of the control panel 20 when the cooling fan 30 drives the airflow to flow from the top to the bottom of the mounting cover 10, thereby increasing the heat dissipation efficiency of the control panel 20 and ensuring its service life. By providing the flow port 22 and the clearance port 21 on the control panel 20, the airflow can flow from the upper surface of the control panel 20 to the bottom, ensuring the airflow efficiency, i.e., ensuring the heat dissipation efficiency.

[0052] Please see Figures 4 to 7 The drive module 200 provided in the second embodiment of this utility model includes a drive motor 210 and the control structure 100 described above.

[0053] The drive motor 210, control panel 20, and cooling fan 30 are arranged from top to bottom. The drive motor 210 has a rotating shaft 40, which passes through the control panel 20 and is connected to the cooling fan 30. The housing of the drive motor 210 is connected to the mounting cover 10.

[0054] The aforementioned control module 200 drives the cooling fan 30 to rotate via the shaft 40 of the drive motor 210. Since the control panel 20 is located between the drive motor 210 and the cooling fan 30, the airflow disturbed by the cooling fan 30 can not only dissipate heat from the drive motor 210, but also from the control panel 20, increasing the contact area between the heat dissipation panel 20 and the airflow and ensuring its service life.

[0055] Understandably, since the control panel 20 is located between the drive motor 210 and the cooling fan 30, in order to protect the electronic components on the control panel 20, the electronic components are located on the side of the control panel 20 facing the cooling fan 30, thereby keeping the electronic components away from the drive motor 210 and avoiding the direct transfer of heat from the drive motor 210 to the electronic components, which would affect the service life of the electronic components.

[0056] In this embodiment, the drive module 200 can be used not only in food processors, but also in noodle makers or other scenarios that require a drive motor, so as to achieve large-area heat dissipation of the drive motor 210 and the control panel 20 by the cooling fan 30 at the same time.

[0057] Please see Figures 8 to 10 The third embodiment of the present invention provides a food preparation cup assembly 300, which includes a food preparation cup structure 310, a shell 320 and the aforementioned drive module 200.

[0058] The food preparation cup structure 310 is located above the mounting cover 10 and includes a cup body 311 and a blending blade 312 located inside the cup body 311. The outer shell 320 is located at the bottom of the cup body 311 and covers the outside of the mounting cover 10, forming an airflow channel 321 between the outer shell 320 and the mounting cover 10.

[0059] Please see Figure 11 The food processor 400 provided in the fourth embodiment of this utility model includes the above-mentioned food processor cup assembly 300 and base 410.

[0060] The base 410 provides an installation space, and the cooking cup assembly 300 is detachably inserted into the installation space. The base 410 can be provided with an air inlet and an air outlet, and the base 410 is provided with a plug. The bottom wall of the cooking cup assembly 300 is provided with a coupler. When the coupler is inserted into the plug of the base 410, the drive motor 210 is electrically connected.

[0061] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
