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] With the development of society and the improvement of living standards, people's pursuit of dietary diversity and healthy diet is constantly increasing. Therefore, various industrial food processing machines are gradually miniaturized and enter thousands of households. For example, soybean milk machines not only meet people's needs for healthy diet and nutrition, but also greatly improve people's quality of life, and are therefore loved by people.

[0003] Existing food processors usually include a machine body, a cup body provided on the machine body and having a grinding chamber, a grinding device provided in the grinding chamber, and a motor provided at the bottom of the cup body and transmission-connected to the grinding device. When using the food processor, the user puts the food into the cup body, and the motor drives the grinding device to rotate at high speed to process the food. However, the motor will generate a lot of heat during the long-term rotation process, and the winding coils and other components on the motor are easily aged due to the heat. In order to reduce the temperature rise of the motor and improve the heat dissipation efficiency of the motor, the air in the machine body is usually driven to flow when the motor rotates to achieve heat dissipation of the motor. However, since the airflow flows in all directions and converges into the motor during the flow process, the gas will collide with various components during the flow process, reducing the flow efficiency of the airflow, thereby reducing the heat dissipation efficiency of the motor. At the same time, in order to achieve the control of motors and other components, the food processor must be equipped with a power board that controls the operation of motors and other components. The operating temperature of the electronic devices on the power board directly determines their service life and stability. During operation, the power board will generate a certain amount of heat, but the air flow through the power board in the machine is small, causing the temperature of the power board to rise rapidly. The continuous heating of the power board may cause the devices on the power board to fail due to overheating, thereby affecting the performance of the food processor and reducing its working reliability. 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 of poor heat dissipation effect of the motor and the power board in the existing food processing machine.

[0005] To achieve the above-mentioned purpose, the utility model provides a food processing machine with good heat dissipation effect, including a shell, a crushing cup installed in the shell, a motor installed under the crushing cup, and a power supply board electrically connected to the motor. A support seat is also provided in the shell, and the support seat is provided with an installation cavity for accommodating the motor and an accommodating cavity for installing the power supply board. The installation cavity and the accommodating cavity are separated by a partition, and a connecting port connecting the installation cavity and the accommodating cavity is provided on the partition. An isolation pad is provided between the upper end surface of the motor and the crushing cup, and the isolation pad is provided with a sleeve portion sleeved on the outer periphery of the motor. The motor housing is provided with a motor air inlet, and the sleeve portion is provided with an air guide structure that connects the accommodating cavity with the motor air inlet through the connecting port.

[0006] The present application provides a mounting cavity for accommodating the motor and an accommodating cavity for installing the power board on the support seat, so that the support seat can not only accommodate the motor, but also install and fix the power board. A single structure can achieve multiple functions, saving the need to set up additional structural components to install the power board, thereby helping to improve the compactness of the entire machine structure and reduce its occupied space. At the same time, the mounting cavity and the accommodating cavity are isolated by a partition, which avoids the situation where the two cavities are completely connected, resulting in a large amount of heat on the motor being transmitted to the accommodating cavity when the food processor is working, causing a significant temperature rise on the power board, causing the aging of electrical components on the power board to accelerate, which helps to protect the power board and extend the service life of the power board. In addition, an isolation pad is provided between the upper end surface of the motor and the crushing cup, which can absorb the vibration of the motor and reduce the vibration noise of the motor. The isolation pad prevents hard collision noise between the motor and the ring ribs, reduces the source of noise and thus reduces noise. At the same time, the isolation pad is provided with a sleeve portion sleeved on the outer periphery of the motor, and the sleeve portion is used to further absorb the vibration of the motor to reduce the generation of noise. At the same time, the pre-installation of the isolation pad is achieved, the assembly is reliable, and the assembly efficiency is improved.

[0007] At the same time, the motor shell is provided with a motor air inlet, and the sleeve portion is provided with an air guide structure which connects the accommodating chamber with the motor air inlet through a connecting port. On the one hand, the airflow entering the shell can first pass through the accommodating chamber and then pass through the installation chamber, that is: the airflow can first cool the power board and then dissipate the heat of the motor, so that the airflow with a lower temperature can dissipate the heat of the power board, increase the temperature difference between the airflow and the power board, and then improve the heat dissipation effect of the power board, further reduce the temperature rise of the power board, and at the same time, the airflow after cooling the power board will pass through the motor again to dissipate the heat of the motor, thereby simultaneously realizing the heat dissipation of the power board and the motor, and can avoid the motor being located upstream of the power board, resulting in the airflow entering the heat dissipation channel having to pass through the motor first and then through the power board, resulting in the airflow that rises in temperature after passing through the motor and the power board when passing through the power board. The smaller temperature difference causes the heat dissipation effect of the power board to deteriorate, thereby ensuring the heat dissipation effect of the motor and the power board; on the other hand, an air guide structure is provided on the sleeve portion, so that the gas from the outside entering the accommodating cavity can be more gathered and smoothly entered into the installation cavity with the guidance of the air guide structure when flowing to the motor air inlet through the connecting port to achieve the heat dissipation of the motor, thereby achieving the effect of gathering and guiding wind, which can further improve the heat dissipation effect of the motor, and avoid the airflow flowing outward through the connecting port from spreading to other structures in the outer shell, resulting in less airflow entering the installation cavity and causing poor heat dissipation effect of the motor; after the airflow is gathered, the airflow velocity in the installation cavity can be accelerated, thereby increasing the flow rate of the airflow passing through the power board per unit time, thereby further improving the heat dissipation effect of the power board and achieving effective heat dissipation of the power board and the motor.

[0008] In a preferred implementation of a food processor with good heat dissipation effect, the air guide structure includes an air guide tube extending from the sleeve portion toward the connecting port.

[0009] By setting the air guide structure to include an air guide tube extending from the socket portion toward the connecting port, the gas flowing outward through the connecting port can directly flow into the installation cavity through the guiding and gathering wind effect of the air guide tube, so as to achieve effective heat dissipation of the motor, which helps to further improve the heat dissipation effect of the power board and the motor. At the same time, the air guide tube can be integrally formed with the isolation pad, and the production process is simple, which helps to improve production efficiency and reduce production costs.

[0010] In a preferred implementation of a food processor with good heat dissipation effect, the free end of the air guide cylinder extends into the accommodating cavity through the connecting port.

[0011] By setting the free end of the air guide tube to extend through the connecting port into the accommodating cavity, the air guide tube can directly guide the airflow in the accommodating cavity into the installation cavity, thereby avoiding the gap between the air guide tube and the connecting port, which causes the air guide tube to guide the airflow outside the gap into the installation cavity in addition to the gas flowing out of the connecting port, resulting in a decrease in the gas flow rate in the accommodating cavity, thereby causing the heat dissipation efficiency of the power board to decrease. The uniqueness of the gas flow is ensured so that the heat dissipation airflow can only pass through the accommodating cavity and then enter the installation cavity through the air guide tube to achieve heat dissipation, which helps to further improve the heat dissipation efficiency. In addition, the air guide tube can be limited by means of the connecting port, thereby achieving the positioning of the entire isolation pad, avoiding the situation where the isolation pad is misassembled during assembly, resulting in the position of the air guide tube not corresponding to the connecting port, thereby affecting the heat dissipation effect.

[0012] In a preferred implementation of a food processor with good heat dissipation effect, the free end of the air guide cylinder has an air guide port corresponding to the position of the connecting port, the caliber of the air guide port is larger than the caliber of the connecting port, and the air guide port abuts against a partition at the edge of the connecting port.

[0013] By providing the free end of the air guide tube with an air guide port corresponding to the position of the connecting port, and the diameter of the air guide port is larger than the diameter of the connecting port, the air guide port can achieve all-round docking with the connecting port, so that the airflow discharged from the connecting port can completely enter the air guide tube, thereby improving the utilization efficiency of the airflow. At the same time, the air guide port abuts against the partition plate at the edge of the connecting port, so that the airflow entering the air guide tube can only be discharged from the connecting port, thereby avoiding the gap between the air guide tube and the connecting port, which causes the air guide port to guide the airflow outside the gap into the installation cavity in addition to the gas flowing out of the connecting port, resulting in a decrease in the gas flow rate in the accommodating cavity, thereby causing the heat dissipation efficiency of the power board to become low, which helps to further improve the heat dissipation efficiency of the power board and the motor.

[0014] In a preferred implementation of a food processor with good heat dissipation effect, the free end of the air guide tube has a supporting rib that separates the top wall and the bottom wall of the air guide tube.

[0015] By providing support ribs at the free end of the air duct to separate the top wall and the bottom wall of the air duct, support is achieved for the outer wall of the air duct. This can effectively prevent the outer wall of the air duct from collapsing inward due to the large negative pressure when air is introduced, resulting in lower air introduction efficiency or even blockage causing poor heat dissipation effect. This ensures the heat dissipation effect and improves the stability of the entire machine.

[0016] In a preferred implementation of a food processor with good heat dissipation effect, the power board includes a board body and a heat sink disposed on the board body, and the heat sink is disposed adjacent to the connecting port.

[0017] By configuring the power board to include a board body and a heat sink disposed on the board body, the heat sink can achieve contact with a larger area of ​​the airflow, thereby increasing the airflow rate passing through the entire power board per unit time, thereby improving the heat dissipation effect. At the same time, the heat sink is disposed near the connecting port, and the airflow velocity at the connecting port is faster, thereby increasing the velocity of the airflow passing through the heat sink, which can further improve the heat dissipation effect.

[0018] In a preferred implementation of a food processor with good heat dissipation effect, the grinding cup is provided with a connection portion which is floatingly supported on a support seat, and the motor is hoisted below the grinding cup.

[0019] By providing the grinding cup with a connection portion that is floatingly supported on the support base, and hoisting the motor under the grinding cup, the entire grinding assembly, that is, the grinding cup and the motor are both floatingly mounted on the support base, so that the motor and the grinding cup can have a certain floating space on the support base. When the user uses the food processor to process food ingredients, the vibration generated by the high-speed rotation of the motor can greatly reduce the transmission of the vibration to the support base during the relative floating process with the support base, thereby effectively avoiding the situation where the vibration of the motor is directly transmitted to the support base, causing the support base to vibrate and drive the whole machine to resonate.

[0020] In a preferred implementation of a food processor with good heat dissipation effect, the connecting part includes a first lug protruding radially outwardly set on the grinding cup, the support seat is provided with a support column protruding upward and cooperating with the first lug, and a shock-absorbing pad is provided between the first lug and the support column.

[0021] By providing a first lug protruding radially outward on the grinding cup, the support seat is provided with a support column protruding upward and cooperating with the first lug, and a shock-absorbing pad is provided between the first lug and the support column, so that after the first lug and the support column cooperate, the two are flexibly separated by the isolation of the shock-absorbing pad, thereby avoiding the situation where the two are in direct contact and vibration noise is easily generated during operation, and at the same time reducing the transmission of vibration from the motor to the support seat when it is working.

[0022] In a preferred implementation of a food processor with good heat dissipation effect, a mounting column is provided on the outer bottom wall of the grinding cup, and a second lug protruding radially outward is provided on the motor. The second lug is fixedly connected to the mounting column so that the motor is hoisted below the grinding cup.

[0023] By providing a mounting column on the outer bottom wall of the grinding cup, the motor is provided with a second lug protruding radially outward, and the second lug is fixedly connected to the mounting column so that the motor can be hoisted under the grinding cup, so that the motor and the grinding cup can be combined into a grinding assembly and then installed into the outer shell together, which is convenient for assembly, and is beneficial to improving the coaxiality of the motor and the grinding cup, improving the rotation balance, and reducing the sway noise of the motor's rotating shaft.

DETAILED DESCRIPTION

[0032] 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.

[0033] 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.

[0034] like Figures 1 to 5As shown, the utility model provides a food processing machine with good heat dissipation effect, including a shell 6, a crushing cup 1 installed in the shell 6, a motor 3 installed below the crushing cup 1, and a power supply board 5 electrically connected to the motor 3. A support base 4 is also provided in the shell 6. The support base 4 is provided with a mounting cavity 43 for accommodating the motor 3 and an accommodating cavity 42 for installing the power supply board 5. The mounting cavity 43 and the accommodating cavity 42 are isolated from each other by a partition 41, and a connecting port 411 connecting the mounting cavity 43 and the accommodating cavity 42 is provided on the partition 41. An isolation pad 2 is provided between the upper end surface of the motor 3 and the crushing cup 1, and the isolation pad 2 is provided with a sleeve portion sleeved on the outer periphery of the motor 3. The housing of the motor 3 is provided with a motor air inlet 31, and the sleeve portion is provided with an air guide structure 21 for connecting the accommodating cavity 42 with the motor air inlet 31 through the connecting port 411.

[0035] The present application provides a mounting cavity 43 for accommodating the motor 3 and an accommodating cavity 42 for installing the power board 5 on the support base 4, so that the support base 4 can not only accommodate the motor 3, but also install and fix the power board 5. A single structure can achieve multiple functions, saving the need for additional structural components to install the power board 5, thereby helping to improve the compactness of the entire structure and reduce its occupied space. At the same time, the mounting cavity 43 and the accommodating cavity 42 are isolated by a partition 41, which prevents the two cavities from being completely connected, resulting in a large amount of heat from the motor 3 being transmitted to the accommodating cavity 42 when the food processor is working, causing the power board 5 to have a significant temperature rise, causing the electrical components on the power board 5 to age faster, and helping to protect the power board 5 and extend the service life of the power board 5. In addition, an isolation pad 2 is provided between the upper end surface of the motor 3 and the grinding cup 1, which can absorb the vibration of the motor 3 and reduce the vibration noise of the motor 3. The isolation pad 2 prevents hard collision noise between the motor 3 and the annular ribs, reduces the source of noise and thus reduces noise. At the same time, the isolation pad 2 is provided with a sleeve portion sleeved on the outer periphery of the motor 3, and the sleeve portion is used to further absorb the vibration of the motor 3 to reduce the generation of noise. At the same time, the isolation pad 2 is pre-installed, the assembly is reliable, and the assembly efficiency is improved.

[0036] At the same time, the shell of the motor 3 is provided with a motor air inlet 31, and the sleeve portion is provided with an air guide structure 21 which connects the accommodating chamber 42 with the motor air inlet 31 through the connecting port 411. On the one hand, the airflow entering the outer shell 6 can first pass through the accommodating chamber 42 and then pass through the installation chamber 43, that is, the airflow can first cool the power board 5 and then dissipate the heat of the motor 3, so that the airflow with a lower temperature can dissipate the heat of the power board 5, increase the temperature difference between the airflow and the power board 5, and then improve the heat dissipation effect of the power board 5, further reduce the temperature rise of the power board 5, and at the same time, after completing the cooling of the power board 5, the airflow will pass through the motor 3 again to dissipate the heat of the motor 3, thereby synchronously realizing the heat dissipation of the power board 5 and the motor 3, and can avoid the motor 3 being located upstream of the power board 5, resulting in the airflow entering the heat dissipation channel having to pass through the motor 3 first and then through the power board 5, resulting in the airflow with a temperature rise after passing through the motor 3 when passing through the power board 5. The small temperature difference of the board 5 causes the heat dissipation effect of the power board 5 to deteriorate, thereby ensuring the heat dissipation effect of the motor 3 and the power board 5; on the other hand, an air guide structure 21 is arranged on the sleeve part, so that the gas from the outside entering the accommodating cavity 42 can be more gathered and smoothly entered into the installation cavity 43 with the guidance of the air guide structure 21 when flowing to the motor air inlet 31 through the connecting port 411 to achieve the heat dissipation of the motor 3, thereby achieving the effect of gathering and guiding wind, and can further improve the heat dissipation effect of the motor 3, and avoid the airflow flowing outward through the connecting port 411 from spreading to other structures in the outer shell 6, resulting in less airflow entering the installation cavity 43, resulting in poor heat dissipation effect of the motor 3, and after the airflow is gathered, the airflow velocity in the installation cavity 43 can be accelerated, thereby increasing the flow rate of the airflow passing through the power board 5 per unit time, thereby further improving the heat dissipation effect of the power board 5, and achieving effective heat dissipation of the power board 5 and the motor 3.

[0037] It should be noted that the present application does not specifically limit the air guide structure 21. A preferred implementation of the present application is as follows: Figure 2 , Figure 3 As shown, the air guide structure 21 includes an air guide tube extending from the sleeve portion toward the communication port 411 .

[0038] By configuring the air guide structure 21 to include an air guide tube extending from the socket portion toward the connecting port 411, the gas flowing outward through the connecting port 411 can directly flow into the installation cavity 43 through the guiding and wind-gathering effect of the air guide tube, so as to achieve effective heat dissipation of the motor 3, which helps to further enhance the heat dissipation effect of the power board 5 and the motor 3. At the same time, the air guide tube can be integrally formed with the isolation pad 2, and the production process is simple, which helps to enhance production efficiency and reduce production costs.

[0039] It should be further explained that the present application does not specifically limit the relative relationship between the air guide tube and the communication port 411, which can be any one of the following embodiments:

[0040] Example 1: Figure 1 As shown, in this embodiment, the free end of the air guide tube extends through the communication port 411 into the accommodating cavity 42 . More preferably, the outer wall of the air guide tube abuts against the wall of the communication port 411 to limit the position.

[0041] By setting the free end of the air guide tube to extend through the connecting port 411 into the accommodating cavity 42, the air guide tube can directly guide the airflow in the accommodating cavity 42 into the installation cavity 43, thereby avoiding the gap between the air guide tube and the connecting port 411, which causes the air guide tube to guide the airflow outside the gap into the installation cavity 43 in addition to the gas flowing out of the connecting port 411, resulting in a decrease in the gas flow rate in the accommodating cavity 42, thereby causing the heat dissipation efficiency of the power board 5 to decrease, ensuring the uniqueness of the gas flow, so that the heat dissipation airflow can only pass through the accommodating cavity 42 and then enter the installation cavity 43 through the air guide tube to achieve heat dissipation, which helps to further improve the heat dissipation efficiency. In addition, the air guide tube can be limited by means of the connecting port 411, thereby achieving the positioning of the entire isolation pad 2, avoiding the situation where the isolation pad 2 is misassembled during assembly, resulting in the position of the air guide tube and the connecting port 411 not corresponding, thereby affecting the heat dissipation effect.

[0042] Embodiment 2: In this embodiment, the free end of the air guide tube has an air guide port 211 corresponding to the position of the connecting port 411 , the diameter of the air guide port 211 is larger than the diameter of the connecting port 411 , and the air guide port 211 abuts against the partition 41 at the edge of the connecting port 411 .

[0043] By providing the free end of the air guide tube with an air guide port 211 corresponding to the position of the connecting port 411, and the diameter of the air guide port 211 is larger than the diameter of the connecting port 411, the air guide port 211 can achieve all-round docking with the connecting port 411, so that the airflow discharged from the connecting port 411 can completely enter the air guide tube, thereby improving the utilization efficiency of the airflow. At the same time, the air guide port 211 abuts against the partition plate 41 at the edge of the connecting port 411, so that the airflow entering the air guide tube can only be discharged from the connecting port 411, thereby avoiding the gap between the air guide tube and the connecting port 411, which causes the air guide port 211 to guide the airflow outside the gap into the installation cavity 43 in addition to the gas flowing out of the connecting port 411, resulting in a decrease in the gas flow rate in the accommodating cavity 42, thereby causing the heat dissipation efficiency of the power board 5 to become low, which helps to further improve the heat dissipation efficiency of the power board 5 and the motor 3.

[0044] As a preferred embodiment of this embodiment, Figure 3 As shown, the free end of the air guide tube has a supporting rib 212 separating the top wall and the bottom wall of the air guide tube.

[0045] By providing a support rib 212 at the free end of the air guide tube to separate the top wall and the bottom wall of the air guide tube, support is achieved for the outer wall of the air guide tube, effectively preventing the outer wall of the air guide tube from collapsing inwards due to a large negative pressure when air is introduced, thereby reducing the air introduction efficiency or even causing blockage and deteriorating the heat dissipation effect, thereby ensuring the heat dissipation effect and improving the stability of the entire machine.

[0046] Of course, the air guide structure 21 in the present application is not limited to the above-mentioned setting, and it can also be a passage provided on the sleeve portion that is connected to the motor air inlet 31. The air guide structure 21 includes an air guide plate extending from the passage to the connecting port 411, and two air guide plates are vertically or laterally arranged opposite to each other, and one end of the air guide plate abuts against the partition plate at the edge of the connecting port 411, and the other end abuts against the sleeve portion at the edge of the passage.

[0047] As a preferred embodiment of the present application, Figure 4 , Figure 5 As shown, the power board 5 includes a board body 51 and a heat sink 52 disposed on the board body 51 , and the heat sink 52 is disposed adjacent to the communication port 411 .

[0048] By configuring the power board 5 to include a board body 51 and a heat sink 52 disposed on the board body 51, the heat sink 52 can achieve contact with a larger area of ​​the airflow, thereby increasing the airflow rate passing through the entire power board 5 per unit time, thereby improving the heat dissipation effect. At the same time, the heat sink 52 is disposed adjacent to the connecting port 411, and the airflow velocity at the connecting port 411 is faster, thereby increasing the velocity of the airflow passing through the heat sink 52, and further improving the heat dissipation effect.

[0049] Furthermore, if Figure 5 As shown, a plurality of heat sinks 52 are provided, and a heat sink gap 521 is formed between two adjacent heat sinks 52 . More preferably, the extension direction of the heat sink gap 521 is the same as the airflow direction in the accommodating cavity 42 .

[0050] It should be noted that the present application does not specifically limit the supporting method of the support base 4. The support base 4 may directly support the motor 3, and the grinding cup 1 may be fixed above the motor 3. Alternatively, the support base 4 may support the motor 3 and the grinding cup 1 at the same time. As a preferred embodiment of the present application, Figure 1 , Figure 2 As shown, the grinding cup 1 is provided with a connection portion which is floatingly supported on the support seat 4 , and the motor 3 is hoisted below the grinding cup 1 .

[0051] By providing the grinding cup 1 with a connection portion that is floatingly supported on the support seat 4, and hoisting the motor 3 under the grinding cup 1, the entire grinding assembly, that is, the grinding cup 1 and the motor 3 are both floatingly mounted on the support seat 4, so that the motor 3 and the grinding cup 1 can have a certain floating space on the support seat 4, so that when the user uses the food processor to process food, the vibration generated by the high-speed rotation of the motor 3 can greatly reduce the transmission of the vibration to the support seat 4 during the relative floating process with the support seat 4, thereby effectively avoiding the situation where the vibration of the motor 3 is directly transmitted to the support seat 4, causing the support seat 4 to vibrate and drive the whole machine to resonate.
