Description

Technical Field

[0001] The utility model relates to the technical field of household electrical appliances, in particular to a food processing machine with good heat dissipation effect. Background Art

[0002] Existing food processors usually include a machine body, a cup body assembly provided on the machine body and having a grinding chamber, a grinding device provided in the grinding chamber, and a motor assembly provided below the cup body assembly and transmission-connected to the grinding device. When using the food processor, the user places the food in the grinding chamber, and the motor assembly drives the grinding device to rotate at high speed to process the food.

[0003] Most of the existing motors are brushed motors, but this type of motor will generate large noise and vibration when working, and the user experience is poor. In order to improve the processing effect, most manufacturers will use brushless motors instead of brushed motors. Brushless motors have many advantages such as long life, low vibration, low noise, and no carbon powder pollution. At the same time, in order to achieve heat dissipation of brushless motors, a heat dissipation channel is usually provided. For example, Chinese utility model patent CN220711234U discloses a food processor with good heat dissipation effect, which is connected to an air outlet duct on the brushless motor, and the air outlet duct and the power board are staggered horizontally to avoid the location of the power board. Although the above-mentioned air outlet duct can achieve air flow guidance, it is set on one side of the power board, which will cause the lateral size of the whole machine to become larger; another food processor sets the entire motor assembly above the power board, so that the air outlet duct can extend outward from the power board, but this structure will cause the vertical size of the whole machine to be too large, which will lead to a higher center of gravity of the whole machine, causing the food processor to swing horizontally when working, vibrate more and generate more noise, which seriously affects the consumer experience. Utility Model Content

[0004] The utility model aims to provide a food processing machine with good heat dissipation effect, so as to solve the problem that the air outlet duct connected to the motor in the existing food processing machine occupies a large space in the machine body, resulting in the over-large size of the whole machine.

[0005] To achieve the above-mentioned purpose, the utility model provides a food processing machine with good heat dissipation effect, including a machine body, a cup body assembly arranged on the machine body and having a grinding chamber, a grinding device arranged in the grinding chamber, and a motor assembly arranged below the cup body assembly and transmission connected to the grinding device. A support seat is provided below the cup body assembly, and the motor assembly is installed on the support seat. The motor assembly includes an upper bracket, a lower bracket and a motor body. The upper bracket and the lower bracket are enclosed to form a accommodating chamber for accommodating the motor body. The lower bracket is provided with an air outlet duct connected to the accommodating chamber and extending outward. A power supply board is also provided in the machine body, which is placed vertically and partially overlapped with the lower bracket in the horizontal direction, and the air outlet duct is provided with a avoidance portion for avoiding the power supply board.

[0006] The present application achieves the fixation of the motor body by setting the motor body in the accommodating cavity formed by the upper bracket and the lower bracket, ensures the reliability of the position of the motor body, and thus can improve the stability of the transmission between the motor body and the crushing device, and avoid the situation that the motor body is not firmly fixed, causing its displacement, resulting in the unstable connection between the motor body and the crushing device and the transmission failure. At the same time, a power board is also provided in the machine body, which is placed vertically and partially overlaps with the lower bracket in the horizontal direction, and the air outlet duct is provided with a avoidance portion for avoiding the power board, so that the airflow for heat dissipation of the motor assembly can be realized by the avoidance portion of the air outlet duct, so that after the power board at the same vertical height is installed in the machine body, the motor assembly can still be installed close to the bottom and can partially overlap with the power board in the horizontal direction, which helps to reduce the vertical size of the whole machine, thereby reducing the center of gravity of the whole machine, and can improve the stability of the whole machine operation, avoid the situation that the center of gravity of the whole machine is high, resulting in large vibration and large noise when the food processor is working, and at the same time improves the utilization rate of the internal space of the machine body, improves the structural compactness of the whole machine, helps to reduce the size of the whole machine, and improves the user experience. In addition, the air outlet duct is integrated on the lower bracket, eliminating the need for a separate air outlet duct structure, which helps to further simplify the structure of the entire machine and eliminates the step of connecting the air outlet duct to the motor, which helps to improve assembly efficiency.

[0007] In a preferred implementation of a food processor with good heat dissipation effect, the support base includes a support surface supported below the motor assembly and a mounting surface connected to the support surface and vertically arranged, a power board is fixed on the mounting surface, and the air outlet duct is provided with an inclined section extending obliquely upward to above the power board, and the avoidance portion includes the inclined section.

[0008] By setting the support base to include a support surface supported under the motor assembly and a mounting surface connected to the support surface and arranged vertically, and a power board is fixed on the mounting surface, the support base can not only realize the support and installation of the motor assembly, but also realize the fixing of the power board, realizing the functional integration of the support base, and at the same time eliminating the need for another structural component to realize the installation of the power board, saving parts, and further improving the structural compactness of the body. In addition, the air outlet duct is provided with an inclined section extending obliquely upward to the top of the power board, and the avoidance portion includes an inclined section. By setting the air outlet duct to extend obliquely upward, avoidance with the power board can be achieved, the structure is simple and easy to produce, and the production cost can be reduced and the production efficiency can be improved. At the same time, the airflow can move smoothly upward along the inclined section, avoiding the situation that the airflow is not smooth due to the setting of the corner, etc., resulting in poor heat dissipation effect of the motor body, which helps to ensure the heat dissipation effect of the motor body, and after the airflow is discharged obliquely upward from the air outlet duct, it can continue to be discharged upward and outward for a distance by inertia, which can keep the airflow away from the power board, thereby avoiding the situation that the high-temperature airflow passes through the power board and causes the power board to heat up significantly and cause serious aging, thereby protecting the power board.

[0009] In a preferred implementation of a food processor with good heat dissipation effect, an angle A between an extension axis of the inclined section and a horizontal plane satisfies: 15°≤A≤45°.

[0010] By setting the angle A between the extension axis of the inclined section and the horizontal plane to satisfy: 15°≤A≤45°, it is avoided that the angle between the extension axis of the inclined section and the horizontal plane is too small, which results in the air outlet duct needing to be extended a long distance to extend above the power board, resulting in the overall lateral dimension of the lower bracket being too large, causing the motor assembly to occupy a large space; at the same time, it is avoided that the angle between the extension axis of the inclined section and the horizontal plane is too large, which results in the corner between the inclined section and the accommodating cavity being too large, resulting in excessive resistance when the airflow moves upward, and further resulting in poor exhaust and poor heat dissipation effect.

[0011] In a preferred implementation of a food processor with good heat dissipation effect, a supporting portion supported on the bottom wall of the inclined section is provided below the inclined section.

[0012] By providing a supporting portion supported on the bottom wall of the inclined section under the inclined section, the inclined section can be maintained in an inclined upward position with the support of the supporting portion, thereby preventing the inclined section from moving downward under its own gravity and overlapping or contacting the power board after long-term use, causing the airflow to blow directly onto the power board, thereby ensuring the reliability of the position of the inclined section and improving the air outlet effect.

[0013] In a preferred implementation of a food processor with good heat dissipation effect, an air outlet is provided at the end of the inclined section, and the vertical projection of the air outlet does not fall into the power board.

[0014] By setting the vertical projection of the air outlet so as not to fall into the power board, the air flow discharged from the air outlet can be directly discharged away from the power board, further avoiding the situation where the hot air discharged from the air outlet passes through the power board, causing the power board to heat up significantly and cause serious aging, thereby protecting the power board.

[0015] In a preferred implementation of a food processor with good heat dissipation effect, the motor body is provided with a motor air outlet, the central axis of the motor air outlet is in the same direction as the central axis of the air outlet duct, and the central axis of the air outlet duct is located outside the central axis of the motor air outlet.

[0016] By setting the central axis of the motor air outlet to be in the same direction as the central axis of the air outlet duct, the air flow discharged from the motor air outlet can directly enter the air outlet duct, so that the air flow can be quickly discharged outward through the air outlet duct, which helps to improve the air outlet efficiency and thus improve the heat dissipation effect. At the same time, the central axis of the air outlet duct is located outside the central axis of the motor air outlet, which can avoid the high electrical components on the power board, thereby reducing the upward inclination angle of the air outlet duct, thereby making the air outlet smoother, which helps to further improve the heat dissipation effect.

[0017] In a preferred implementation of a food processor with good heat dissipation effect, an inner wall of a lower bracket located at an inner port of an air outlet duct is provided with an inwardly extending drainage portion, and an extended end of the drainage portion abuts against an air outlet port of the motor.

[0018] By setting the extended end of the guide part to abut against the motor outlet port, the gas discharged from the motor outlet can be discharged outward from the air outlet duct with the help of the guiding effect of the guide part, thereby preventing the air flow from being discharged outward from the gap between the lower bracket and the motor body bracket, resulting in low air outlet efficiency and further deterioration of the heat dissipation effect of the motor body.

[0019] In a preferred implementation of a food processor with good heat dissipation effect, the drainage portion is provided with an arc-shaped guide surface extending from the motor air outlet to the air outlet duct.

[0020] By providing an arc-shaped guide surface extending from the motor air outlet to the air outlet duct on the guide part, the airflow can smoothly enter the air outlet duct with the help of the guiding effect of the arc-shaped guide surface when flowing from the motor air outlet to the air outlet duct, thereby reducing the energy loss of the airflow during flow, ensuring the efficiency of the gas flow, and further ensuring the heat dissipation effect of the motor body.

[0021] In a preferred implementation of a food processor with good heat dissipation effect, a heat dissipation fan is provided at the bottom end of the rotating shaft of the motor body, and the extension axis of the air outlet duct is colinear with the tangent of the rotating path of the heat dissipation fan.

[0022] By setting the extension axis of the air outlet duct to be colinear with the tangent of the rotation path of the cooling fan, the airflow driven by the cooling fan can be discharged directly outward through the air outlet duct, which can reduce the energy loss when the airflow is discharged, the discharge flow rate is faster, and the heat dissipation effect is further improved.

DETAILED DESCRIPTION

[0031] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0032] It should be noted that many specific details are elaborated in the following description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific implementation methods disclosed below.

[0033] like Figures 1 to 5 As shown, the utility model provides a food processing machine with good heat dissipation effect, including a machine body, a cup body assembly 1 arranged on the machine body and having a grinding chamber 11, a grinding device 2 arranged in the grinding chamber 11, and a motor assembly 4 arranged below the cup body assembly 1 and transmission connected to the grinding device 2. A support seat 3 is provided below the cup body assembly 1, and the motor assembly 4 is installed on the support seat 3. The motor assembly 4 includes an upper bracket 5, a lower bracket 7 and a motor body 6. The upper bracket 5 and the lower bracket 7 are enclosed to form an accommodating chamber 72 for accommodating the motor body 6. The lower bracket 7 is provided with an air outlet duct 71 which is connected to the accommodating chamber 72 and extends outward. A power supply board 8 which is placed vertically and partially overlaps with the lower bracket 7 in the horizontal direction is also provided in the machine body, and the air outlet duct 71 is provided with a avoidance portion for avoiding the power supply board 8.

[0034] The present application achieves the fixation of the motor body 6 by disposing the motor body 6 in the accommodating cavity 72 formed by the upper bracket 5 and the lower bracket 7, thereby ensuring the reliability of the position of the motor body 6, thereby improving the stability of the transmission between the motor body 6 and the crushing device 2, and avoiding the situation where the motor body 6 is not firmly fixed and causes its displacement, resulting in an unstable connection between the motor body 6 and the crushing device 2 and causing transmission failure. At the same time, a power board 8 is also provided in the machine body, which is placed vertically and partially overlaps with the lower bracket 7 in the horizontal direction, and the air outlet duct 71 is provided with an avoidance portion for avoiding the power board 8, so that the airflow for dissipating heat to the motor assembly 4 can be discharged with the help of the avoidance portion of the air outlet duct 71, so that after the power board 8 at the same vertical height is installed in the machine body, the motor assembly 4 can still be installed close to the bottom and can partially overlap with the power board 8 in the horizontal direction, which helps to reduce the vertical size of the whole machine, thereby reducing the center of gravity of the whole machine, and can improve the stability of the whole machine operation, avoid the situation where the center of gravity of the whole machine is high, resulting in large vibrations and large noises when the food processor is working, and at the same time improve the utilization rate of the internal space of the machine body, improve the compactness of the structure of the whole machine, help to reduce the size of the whole machine, and improve the user experience. In addition, the air outlet duct is integrated on the lower bracket 7, eliminating the structure of the air outlet duct, which helps to further simplify the structure of the whole machine, and eliminates the step of connecting the air outlet duct to the motor, which helps to improve the assembly efficiency.

[0035] It should be noted that the present application does not specifically limit the structure of the avoidance portion. As a preferred implementation of the present application, Figure 3 As shown, the support base 3 includes a support surface 31 supported below the motor assembly 4 and a mounting surface 32 connected to the support surface 31 and vertically arranged, a power board 8 is fixed on the mounting surface 32, and the air outlet duct 71 is provided with an inclined section 711 extending obliquely upward to above the power board 8, and the avoidance portion includes the inclined section 711.

[0036] By configuring the support base 3 to include a support surface 31 supported below the motor assembly 4 and a mounting surface 32 connected to the support surface 31 and vertically arranged, and a power board 8 is fixed on the mounting surface 32, the support base 3 can not only support and install the motor assembly 4, but also fix the power board 8, thereby realizing the functional integration of the support base 3 and eliminating the need for additional structural components to install the power board 8, thereby saving components and further improving the structural compactness of the machine body. In addition, the air outlet duct 71 is provided with an inclined section 711 extending upwardly at an angle to the top of the power board 8, and the avoidance portion includes the inclined section 711. By setting the air outlet duct 71 to extend upward at an angle, avoidance with the power board 8 can be achieved. The structure is simple and easy to produce, which can reduce production costs and improve production efficiency. At the same time, the airflow can move smoothly upward along the inclined section 711, avoiding the poor heat dissipation effect of the motor body 6 caused by the poor airflow circulation caused by the settings such as corners, which helps to ensure the heat dissipation effect of the motor body 6. After the airflow is discharged from the air outlet duct 71 at an angle, it can continue to be discharged upward and outward for a distance by inertia, which can keep the airflow away from the power board 8, thereby avoiding the high-temperature airflow passing through the power board 8, causing the power board 8 to heat up significantly and cause serious aging, thereby protecting the power board 8.

[0037] It should be further explained that the present application does not specifically limit the inclination angle of the inclined section 711. As a preferred embodiment of the present application, Figure 3 As shown, the included angle A between the extension axis of the inclined section 711 and the horizontal plane satisfies: 15°≤A≤45°. More preferably, A is 30°, 40° or 45°.

[0038] By setting the angle A between the extension axis of the inclined section 711 and the horizontal plane to satisfy: 15°≤A≤45°, it is avoided that the angle between the extension axis of the inclined section 711 and the horizontal plane is too small, which results in the air outlet duct 71 needing to be extended a long distance to extend above the power board 8, resulting in the overall lateral dimension of the lower bracket 7 being too large, causing the motor assembly 4 to occupy a large space; at the same time, it is avoided that the angle between the extension axis of the inclined section 711 and the horizontal plane is too large, which results in the corner between the inclined section 711 and the accommodating cavity 72 being too large, resulting in excessive resistance when the airflow moves upward, and further resulting in poor exhaust and poor heat dissipation.

[0039] As a preferred embodiment of this embodiment, Figure 3 As shown, a support portion 7111 supported on the bottom wall of the inclined section 711 is provided below the inclined section 711 .

[0040] By providing a support portion 7111 supported on the bottom wall of the inclined section 711 below the inclined section 711, the inclined section 711 can be maintained in an inclined upward position with the support of the support portion 7111, thereby preventing the inclined section 711 from moving downward under its own gravity and overlapping or contacting the power board 8 after long-term use, causing the airflow to blow directly onto the power board 8, thereby ensuring the reliability of the position of the inclined section 711 and improving the air outlet effect.

[0041] It should be noted that the present application does not specifically limit the structure of the support portion 7111, which may be any one of the following embodiments:

[0042] Example 1: Figure 3 As shown, in this embodiment, the support portion 7111 includes a first support rib extending downwardly and arranged on the bottom wall of the inclined section 711 , and the bottom end of the first support rib abuts against the support seat 3 .

[0043] Embodiment 2: In this embodiment, the support portion 7111 includes a second support rib extending upwardly and arranged on the top wall of the support seat 3 , and the top end of the second support rib abuts against the bottom wall of the inclined section 711 .

[0044] As a preferred embodiment of the present application, Figure 3 As shown, an air outlet is provided at the end of the inclined section 711 , and the vertical projection of the air outlet does not fall into the power board 8 .

[0045] By setting the vertical projection of the air outlet so as not to fall into the power board 8, the airflow discharged from the air outlet can be directly discharged away from the power board 8, further avoiding the situation where the hot air discharged from the air outlet passes through the power board 8, causing the power board 8 to heat up significantly and cause serious aging, thereby protecting the power board 8.

[0046] Of course, the avoidance portion is not limited to the above-mentioned setting. It can also be that the air outlet duct 71 is provided with a first horizontal and vertical section extending laterally, a vertical section connected to the first horizontal and vertical section and extending vertically, and a second horizontal and vertical section connected to the vertical section and extending laterally outward, the second horizontal and vertical section is located above the power board 8, and the avoidance portion includes the vertical section and the second horizontal and vertical section.

[0047] As a preferred embodiment of the present application, Figure 4 As shown, the motor body 6 is provided with a motor air outlet 61 , the central axis of the motor air outlet 61 is in the same direction as the central axis of the air outlet duct 71 , and the central axis of the air outlet duct 71 is located outside the central axis of the motor air outlet 61 .

[0048] By setting the central axis of the motor air outlet 61 to be in the same direction as the central axis of the air outlet duct 71, the air flow discharged outward from the motor air outlet 61 can directly enter the air outlet duct 71, so that the air flow can be quickly discharged outward through the air outlet duct 71, which helps to improve the air outlet efficiency and thus improve the heat dissipation effect. At the same time, the central axis of the air outlet duct 71 is located outside the central axis of the motor air outlet 61, which can avoid the electrical components with a height on the power board 8, thereby reducing the upward inclination angle of the air outlet duct 71, thereby making the air outlet smoother, which helps to further improve the heat dissipation effect.

[0049] As a preferred embodiment of this embodiment, Figure 4 , Figure 5 As shown, the inner wall of the lower bracket 7 located at the inner end of the air outlet duct 71 is provided with a guide portion 73 extending inwardly, and the extended end of the guide portion 73 abuts against the end of the motor air outlet 61.

[0050] By setting the extended end of the guide part 73 to abut against the port of the motor air outlet 61, the gas discharged from the motor air outlet 61 can be discharged outward from the air outlet duct 71 with the help of the guiding effect of the guide part 73, thereby preventing the air flow from being discharged outward from the gap between the lower bracket 7 and the motor body 6 bracket, resulting in low air outlet efficiency and further causing the heat dissipation effect of the motor body 6 to deteriorate.

[0051] Furthermore, if Figure 4 , Figure 5 As shown, the guide portion 73 is provided with an arc-shaped guide surface 731 extending from the motor air outlet 61 to the air outlet duct 71 .

[0052] By providing an arc-shaped guide surface 731 extending from the motor air outlet 61 to the air outlet duct 71 on the guide portion 73, when the airflow flows through the motor air outlet 61 to the air outlet duct 71, it can smoothly enter the air outlet duct 71 with the help of the guiding effect of the arc-shaped guide surface 731, thereby reducing the energy loss of the airflow during flow, ensuring the efficiency of the gas flow, and further ensuring the heat dissipation effect of the motor body 6.

[0053] As a preferred embodiment of the present application, Figure 4 As shown, a cooling fan 9 is provided at the bottom end of the rotating shaft of the motor body 6 , and the extension axis of the air outlet duct 71 is colinear with the tangent line of the rotating path of the cooling fan 9 .

[0054] By setting the extension axis of the air outlet duct 71 to be colinear with the tangent of the rotation path of the cooling fan 9, the airflow driven by the cooling fan 9 can be directly discharged outward through the air outlet duct 71, which can reduce the energy loss during the discharge of the airflow, make the discharge flow rate faster, and further improve the heat dissipation effect.

[0055] The technical solution protected by the present utility model is not limited to the above-mentioned embodiments. It should be pointed out that the combination of the technical solution of any embodiment with the technical solution of one or more other embodiments is within the protection scope of the present utility model. Although the present utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to it based on the present utility model. Therefore, these modifications or improvements made without departing from the spirit of the present utility model are within the scope of protection claimed by the present utility model.
