Abstract
Description
Technical Field
[0001] This utility model relates to the field of food processor technology, and in particular to a drive mechanism, a food processor cup assembly, 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 preparing beauty masks for women.
[0003] Typically, the electronic components inside a food processor (such as the control board and drive motor) generate heat during use. Therefore, food processors usually have a fan installed to blow airflow into the control board and drive motor for cooling. The control panel and drive motor are generally separate, with the control panel mounted in the base. The drive motor and cooling fan are coaxially mounted. The base has air inlets and exhaust vents. Outside air is driven by the fan to enter the base through the air inlets. The air flows over the control panel and then towards the drive motor, carrying the heat generated by the control board and drive motor out through the exhaust vents, thus cooling the food processor. However, because the control panel is mounted in the base, the air inlets on the base are relatively small, which cannot achieve large-area heat dissipation for the control panel, thus affecting its lifespan. Utility Model Content

[0005] Windproof cover;

[0007] A control panel is located below the drive motor and connected to the housing of the drive motor, and is used to control the start and stop of the drive motor;
[0008] A cooling fan is located below the control panel and connected to one end of the output shaft so that it can be driven to rotate by the drive motor, thereby driving airflow from outside the fan shroud to inside the fan shroud.
[0009] In some embodiments, the drive motor and the control panel are spaced apart.
[0010] In some embodiments, the spacing ranges from 3.0cm to 5.0cm.

[0017] A third aspect of this utility model is to provide a food processor, including the aforementioned food processor cup assembly.
[0018] In summary, the drive mechanism, blending cup assembly, and blender provided by this utility model have the following technical effects:
[0019] By setting up a fan shroud to create a space for airflow, the output shaft of the drive motor drives the cooling fan to rotate, and the control panel is located below the drive motor. When the cooling fan rotates, the airflow flows from the top of the fan shroud to the bottom, which not only cools the drive motor but also simultaneously cools the control panel. This allows for large-area heat dissipation for both, improving heat dissipation efficiency and ensuring the service life of the drive motor and control panel. Attached Figure Description

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 drive mechanism 100 provided in the first embodiment of this utility model includes a fan cover 10, a drive motor 20, a control panel 30, and a cooling fan 40.
[0037] The fan cover 10 has an installation space 11; the drive motor 20 is at least partially located inside the fan cover 10 and has an output shaft 22; the control panel 30 is located below the drive motor 20 and connected to the housing 21 of the drive motor 20, and is used to control the start and stop of the drive motor 20; the cooling fan 40 is located below the control panel 30 and connected to one end of the output shaft 22, so that it can be driven to rotate by the drive motor 20, so that the driving airflow flows from outside the fan cover 10 to inside the fan cover 10.
[0038] The aforementioned drive mechanism 100, by setting up a fan cover 10 to form a space for airflow, drives the cooling fan 40 to rotate through the output shaft 22 of the drive motor 20, and the control panel 30 is located below the drive motor 20. When the cooling fan 40 rotates, the airflow flows from the top to the bottom of the fan cover 10, which not only cools the drive motor 20, but also simultaneously cools the control panel 30. It can simultaneously provide large-area heat dissipation for both, improves heat dissipation efficiency, and ensures the service life of the drive motor 20 and the control panel 30.
[0039] Understandably, the drive motor 20 includes a housing 21, a stator and a rotor disposed within the housing 21, and also includes an output shaft 22 connected to a cooling fan 40, thereby driving the cooling fan 40 to rotate. When the drive mechanism 100 is applied to the food processor 300, the output shaft 22 of the drive motor 20 includes two output ends, one output end for connecting to the mixing blade 220, and the other output end for connecting to the cooling fan 40.
[0040] In this embodiment, the output shaft 22 passes through the control panel 30, meaning the control panel 30 is arranged in a ring shape around the output shaft 22. Compared to existing control panel designs, this increases the coverage area of the control panel 30, allowing for a larger contact area with the airflow and facilitating rapid heat dissipation. Since the control panel 30 includes a circuit board 31 and electronic components 32 mounted on it, this effectively increases the airflow contact area of the circuit board 31, thereby improving heat exchange efficiency.
[0041] Further, please refer to Figures 4 to 7 In one embodiment of this utility model, in order to avoid the drive motor 20 transferring too much heat to the control panel 30 during operation, the drive motor 20 and the control panel 30 are spaced apart. Thus, by setting the distance between the two, not only can the heat transfer from the rotor of the drive motor 20 to the control panel 30 during operation be reduced, but the distance between the two can also help the airflow to achieve heat dissipation of the control panel 30.
[0042] The spacing ranges from 3.0cm to 5.0cm. This spacing setting ensures that the distance between the two components is not too large, avoiding excessive vertical space occupation when installed on the machine. It also prevents the distance from being too small, which would obstruct heat transfer from the drive motor 20 to the control panel 30, and also avoids obstructing airflow to the control panel 30. For example, the distance between them can be set to values such as 3.0cm, 4.0cm, or 5.0cm, and is not limited here.
[0043] Please see Figures 4 to 6 In one embodiment of this utility model, since the control panel 30 includes a circuit board 31 and an electronic device 32 disposed on the circuit board 31, in order to avoid the influence of high heat on the control panel 30, the electronic device 32 is disposed on the side of the circuit board 31 facing the cooling fan 40. In this way, the electronic device 32 is disposed away from the drive motor 20, avoiding the direct transfer of heat from the drive motor 20 to the electronic device 32, and reducing the influence of the heat generated by the drive motor 20 on the control panel 30.
[0044] Understandably, there is also a gap between the electronic device 32 and the cooling fan 40 so that the airflow can flow towards the cooling fan 40 after passing through the control panel 30, so that the airflow can carry away the heat generated on the control panel 30 and achieve heat dissipation of the control panel 30.
[0045] In the prior art, the control panel 30 is mounted on the base, resulting in a small contact area with the airflow. The control panel 30 is also equipped with multiple heat dissipation fin groups, each of which includes at least seven heat dissipation fins arranged in parallel. This allows for heat exchange between the multiple heat dissipation fin groups and the airflow, thereby quickly dissipating the heat from the control panel 30 during use.
[0046] Please see Figure 6 In one embodiment of this utility model, the control panel 30 is also provided with a heat dissipation fin assembly 50. However, since the control panel 30 is located between the drive motor 20 and the cooling fan 40, it can have a large contact area with the airflow. Therefore, compared with the prior art method of setting heat dissipation fins on the control panel 30, this embodiment only needs to set one heat dissipation fin assembly 50, and the number of heat dissipation fins 51 is in the range of 8-11 pieces. Since the control panel 30 already has a large contact area with the airflow, setting one heat dissipation fin and setting a small number of heat dissipation fins can quickly achieve the cooling of the control panel 30.
[0047] Please see Figures 4 to 7 In one embodiment of this utility model, when installing the control panel 30, since the output shaft 22 of the drive motor 20 passes through the control panel 30, i.e., the control panel 30 surrounds the output shaft 22, in order to achieve the installation of the annular control panel 30, the housing 21 of the drive motor 20 is provided with a mounting post 23 on the side facing the control panel 30, and the control panel 30 is provided with a mounting hole 33. The mounting hole 33 and the mounting post 23 are connected by bolts. In this way, by setting the mounting hole 33 and the mounting post 23, the control panel 30 is fixed after being connected by bolts. In other embodiments, a supporting step can also be formed on the inner wall of the fan cover 10 to support the control panel 30, thereby achieving the installation of the control panel 30.
[0048] Understandably, since the control panel 30 has a large cross-sectional area, in order to ensure the installation stability of the control panel 30, the housing 21 is provided with multiple mounting posts 23, and the control panel 30 is provided with multiple mounting holes 33. The multiple mounting posts 23 and the multiple mounting holes 33 are connected one-to-one. In this way, through the arrangement of multiple mounting holes 33 and multiple mounting posts 23, the control panel 30 can have multiple connection points with the housing 21 of the drive motor 20. The multiple connection points share the tensile force and gravity from the control panel 30, thus ensuring the installation stability of the control panel 30.
[0049] Furthermore, since the control panel 30 and the cooling fan 40 are coaxially arranged, that is, the output shaft 22 of the drive motor 20 passes through the control panel 30 and is connected to the drive motor 20, the drive motor 20 drives the cooling fan 40 to rotate during operation. In order to avoid the drive of the control panel 30 to rotate, the control panel 30 is provided with a clearance opening 34 for the output shaft 22 to pass through. The distance between the side wall of the clearance opening 34 and the output shaft 22 is 2cm-5cm, that is, a large clearance opening 34 is provided in the middle of the control panel 30. The output shaft 22 passes through the clearance opening 34 to connect with the cooling fan 40. Furthermore, by setting a certain distance between the clearance opening 34 and the output shaft 22, when the airflow flows from the upper part of the fan cover 10 to the lower part, the airflow flows through the clearance opening 34, which helps the airflow to flow downward and helps to dissipate heat from the control panel 30.
[0050] When setting the distance between the side wall and the pivot of the 34-port avoidance point, it can be set to a value such as 2cm, 3cm, 4cm or 5cm, and is not limited here.
[0051] Further, please refer to Figure 1 When installing the control panel 30, it is connected to the drive motor 20. Therefore, when placed inside the fan shroud 10, it is fitted with the inner wall of the fan shroud 10 with a gap, allowing for a certain gap between the control panel 30 and the inner wall of the fan shroud 10. This facilitates the installation of the control panel 30 within 231 and reduces installation difficulty. For example, when the two are fitted with a gap, the gap range is set to 0-0.3mm. For example, the fitting gap 231 can be 0, 0.1mm, 0.2mm, 0.3mm, etc., to avoid the gap 231 being too large, which would prevent the airflow from flowing too much to the surface of the control panel 30 and thus lose its heat dissipation effect on the control panel 30.
[0052] Furthermore, when the inner wall gap between the control panel 30 and the fan shroud 10 is set, in order to ensure the efficiency of airflow flowing to the lower part of the fan shroud 10, the control panel 30 is provided with an airflow port 35 for airflow. Thus, through the setting of the airflow port 35, when the airflow flows over the control panel 30, it can flow downwards from the control panel 30, reducing wind resistance and improving the efficiency of airflow, so as to remove the heat generated on the control panel 30.
[0053] Specifically, in this embodiment, the flow port 35 extends to the edge of the control panel 30, thereby facilitating the setting of the flow port 35 on the control panel 30. Compared with the method of opening the flow port 35 in the middle area of the control panel 30, the difficulty of opening the flow port 35 is reduced.
[0054] Understandably, in order to ensure the downward flow of air, the control panel 30 is provided with multiple air inlets 35. The multiple air inlets 35 are arranged circumferentially around the output shaft 22 on the control panel 30, so that the control panel 30 can be provided with air inlets 35 at various positions near the fan cover 10, so that the airflow can flow downward from various areas of the control panel 30 and ensure the heat dissipation effect of the control panel 30.
[0055] Among them, the outlet 12 of the wind shield 10 is as follows Figure 2 As shown.
[0056] The aforementioned drive mechanism 100, by housing the drive motor 20, control panel 30, and cooling fan 40 within a single shroud 10, allows the cooling fan 40 to rotate when driven by the drive motor 20, resulting in airflow into the shroud 10. This not only cools the drive motor 20 but also the control panel 30. Compared to mounting the drive motor 20 and control panel 30 in separate housings, this increases the heat dissipation area of the control panel 30, ensuring its lifespan. By placing the electronic components 32 on the control panel 30 on the side away from the drive motor 20, the heat generated by the drive motor 20 is reduced from being transferred to the electronic components 32. The control panel 30 is mounted by providing mounting posts 23 on the housing 21 of the drive motor 20.
[0057] Please see Figures 8 to 10 In a second embodiment, the present invention also provides a food preparation cup assembly 200, including a food preparation cup 210, a stirring blade 220, an outer cover 230, and the aforementioned drive mechanism 100.
[0058] The food preparation cup 210 is used to hold the food to be processed; the mixing blade 220 is located inside the food preparation cup 210 and is used to crush the food; in the aforementioned drive mechanism 100, the other end of the output shaft 22 of the drive motor 20 is connected to the mixing blade 220, thereby driving the mixing blade 220 to rotate and crush the food; the outer cover 230 is located at the bottom of the food preparation cup 210 and covers the drive mechanism 100, forming a gap 231 between it and the fan cover 10 for airflow, and is used to connect with the food preparation cup 210. In this way, airflow flows from the gap 231 into the fan cover 10 and flows out through the fan cover 10.
[0059] When the cooling fan 40 drives airflow, please refer to... Figure 8The outer cover 230 is provided with an air inlet 232 and an air outlet 233. The airflow flows in from the air inlet 232 of the outer cover 230, enters the gap 231 between the outer cover 230 and the fan cover 10, and then flows into the fan cover 10 to dissipate heat from the drive motor 20 and the control panel 30. Then it flows out to the outlet 12 at the lower end of the fan cover 10, and finally flows out from the air outlet 233 of the outer cover 230, thereby achieving the effect of heat dissipation.
[0060] The aforementioned blending cup assembly 200 integrates the drive motor 20, control panel 30, and cooling fan 40 within a single shroud 10. When the cooling fan 40 is driven by the drive motor 20, airflow enters the shroud 10, cooling both the drive motor 20 and the control panel 30. Compared to installing the drive motor 20 and control panel 30 in separate housings, this increases the heat dissipation area of the control panel 30, ensuring its lifespan and thus the overall lifespan of the blending cup assembly 200.
[0061] Please see Figure 11 The third embodiment of this utility model provides a food processor 300, which includes a base 310 and the aforementioned food processor cup assembly 200.
[0062] The outer cover 230 drives the entire cooking cup assembly 200 to be installed on the base 310. The base 310 has a mounting cavity, in which the cooking cup assembly 200 is detachably installed. The base 310 can be provided with corresponding air vents, which are connected to the air inlet 232 and the air outlet 233 respectively. The base 310 is provided with a plug, and the bottom wall of the cooking cup assembly 300 is provided with a coupler 240. When the coupler 240 is plugged into the plug of the base 310, the drive motor 210 is electrically connected.
[0063] In the aforementioned food processor 300, the drive motor 20 for mixing and the control panel 30 are all installed together with the cooling fan 40 inside a fan shroud 10. When the cooling fan 40 is driven by the drive motor 20, airflow flows into the fan shroud 10, which not only cools the drive motor 20 but also the control panel 30. Compared to installing the drive motor 20 and the control panel 30 in different bases, this increases the heat dissipation area of the control panel 30, ensuring the service life of the control panel 30 and the entire food processor 300.
[0064] 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.
