Description
Technical Field
[0001] The utility model relates to the technical field of household electrical appliances, in particular to a food processor with good heat dissipation effect. Background Art
[0002] Existing food processors typically include a main unit and a removable cup assembly mounted on the main unit. The cup assembly includes a cup, a motor mounted below the cup, and a cup holder secured to the bottom of the cup. When using the food processor, the user places food into the cup, and the motor drives the grinding device to rotate at high speed to process the food. To improve the stability of the operating process and reduce noise, a brushless motor is typically used. To control the brushless motor components, a power supply board is essential for controlling the brushless motor. Therefore, simply replacing the existing series-wound motor installation method with a brushless motor fails to effectively dissipate heat from the brushless motor and power supply board. During operation, the power supply board, particularly the IPM module, generates significant heat, causing the power supply board's temperature to rise rapidly. Continued heating of the power supply board can cause components on the board to fail due to overheating, thereby affecting the performance of the food processor and reducing its reliability.
[0003] In addition, some manufacturers place the power board inside the main unit. At the same time, in order to save the horizontal space of the main unit, the power board is usually placed directly below the brushless motor. This greatly increases the circumferential size of the entire main unit, causing the center of gravity of the cup body assembly to be greatly increased after it is installed on the main unit. This in turn causes the cup body to swing greatly or even tip over during the food processing process, seriously affecting the consumer experience. Utility Model Content
[0004] The purpose of the utility model is to provide a food processor with good heat dissipation effect, so as to solve the technical problems that in the existing food processor, when the brushless motor is arranged in the cup body and the power board is arranged in the main body, the heat dissipation structure is complicated when both the brushless motor and the power board need to dissipate heat, and the volume of the whole food processor structure is increased due to the brushless motor, the power board and the heat dissipation structure.
[0005] To achieve the above-mentioned purpose, the utility model provides a food processing machine with good heat dissipation effect, comprising a main unit and a detachable cup body assembly arranged on the main unit, the cup body assembly comprising a cup body, a brushless motor arranged below the cup body and a cup seat fixedly connected to the bottom of the cup body, the cup seat and the cup body enclose forming an installation cavity for accommodating the brushless motor, the main unit comprising a main unit shell, the top of the main unit shell is concave to form an accommodating groove for accommodating the cup body assembly, an accommodating cavity is also formed in the main unit shell in front of the accommodating groove, a power supply board that cooperates with the brushless motor and is placed vertically is provided in the accommodating cavity, the power supply board and the brushless motor at least partially overlap in the horizontal direction, and the accommodating cavity and the installation cavity are provided with heat dissipation channels that are interconnected, and the power supply board is arranged upstream of the gas flow path of the brushless motor in the heat dissipation channel.
[0006] The present application sets a brushless motor in the food processor, and by utilizing the characteristics of the brushless motor, the user can use the food processor to process food ingredients with lower motor rotation noise, thereby achieving noise reduction. At the same time, the brushless motor can realize variable frequency control, so that the food processor can control the brushless motor to output different speeds according to different food ingredients and processing processes, which can achieve better and more complete processing effects on food ingredients and improve the taste of the food products. In addition, the brushless motor occupies less space, which helps to improve the compactness of the internal structure of the entire machine and greatly reduces the axial size of the brushless motor and the cup body.
[0007] The top of the main body shell is recessed to form a receiving slot for the cup assembly. This allows the cup assembly to be effectively positioned within the receiving slot after installation on the main body, improving the stability of the connection between the cup assembly and the main body, thereby preventing the cup assembly from swinging significantly during food processing, which could cause noise or even interrupt food processing. Furthermore, the main body shell includes a receiving chamber located in front of the receiving slot. A vertically positioned power board is housed within the receiving chamber, which is compatible with the brushless motor. The power board and the brushless motor at least partially overlap laterally, effectively utilizing the lateral space within the main body. Compared to existing methods that place the receiving chamber below the receiving slot, this further reduces the axial dimensions of the main body, thereby lowering the center of gravity of the entire main body and the cup assembly. This effectively improves the stability of the entire machine during operation and further enhances the stability of the cup assembly during food processing. Furthermore, the contact area between the main body and the desktop is expanded, further enhancing the stability of the main body.
[0008] In addition, the accommodating cavity and the mounting cavity are provided with heat dissipation channels that are interconnected, so that the brushless motor and the power board can achieve effective heat dissipation in the heat dissipation channels, which can effectively reduce the temperature rise of the brushless motor and the power board, and avoid the situation where the temperature rise of the brushless motor and the power board is obvious, resulting in accelerated aging. In this way, the brushless motor and the power board can be electrically connected while achieving synchronous heat dissipation of the two, thereby achieving reliable control and heat dissipation of the entire machine.
[0009] In addition, the power board is arranged upstream of the brushless motor in the gas flow path of the heat dissipation channel, that is, the airflow can first cool the power board and then dissipate the heat of the brushless 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, after completing the cooling of the power board, the airflow will pass through the brushless motor again to dissipate the heat of the brushless motor, avoiding the brushless motor being located upstream of the power board, resulting in the airflow entering the heat dissipation channel having to pass through the brushless motor first and then through the power board, resulting in the airflow with a temperature rise after passing through the brushless motor having a small temperature difference with the power board when passing through the power board, resulting in a worse heat dissipation effect of the power board, thereby ensuring the heat dissipation effect of the brushless motor and the power board.
[0010] In a preferred implementation of a food processor with good heat dissipation effect, the food processor further includes a control panel for user operation, which is vertically placed in the accommodating cavity and located in front of the power board.
[0011] By placing the control board vertically within the cavity, the space within the main unit is further optimized. Furthermore, the control board's location within the cavity allows airflow to pass not only through the power board but also through the control board, dissipating heat for the control board and further improving the overall cooling performance of the entire unit. Furthermore, the control board is located in front of the power board, ensuring that users can touch the control board from the front of the main unit, enhancing the user experience.
[0012] In a preferred implementation of a food processor with good heat dissipation effect, a mounting bracket is further provided in the accommodating cavity, and the power board and the control board are fixed on opposite sides of the mounting bracket.
[0013] By providing a mounting bracket in the accommodating cavity, and fixing the power board and the control board on opposite sides of the mounting bracket, on the one hand, the power board and the control board can be installed and fixed by using one mounting bracket, thereby realizing the functional integration of the mounting bracket, helping to improve the compactness of the structure inside the host and reducing the space occupied by the entire machine; on the other hand, the power board and the control board can be isolated by the mounting bracket, effectively reducing the transfer of heat from the power board to the control board, avoiding the situation where the temperature rise of the control board is obvious and the aging of the control board is accelerated, and helping to extend the service life of the control board.
[0014] In a preferred implementation of a food processor with good heat dissipation effect, the brushless motor includes a motor housing and a motor body arranged in the motor housing, and the heat dissipation channel includes a heat dissipation cavity formed by the motor housing and an air inlet channel and an air outlet channel connected to the heat dissipation cavity.
[0015] By setting the heat dissipation channel to include a heat dissipation cavity formed by the motor housing and an air inlet channel and an air outlet channel connected to the heat dissipation cavity, the outside air can enter the heat dissipation cavity through the air inlet channel, so that the airflow can directly and effectively dissipate heat to the motor body, which helps to further improve the heat dissipation effect. At the same time, the hot air flow after heat dissipation can be discharged outward through the air outlet channel, realizing a complete heat dissipation path.
[0016] In a preferred implementation of a food processor with good heat dissipation effect, the air inlet channel includes a first air inlet channel provided in the accommodating cavity and connected to the outside, and a second air inlet channel provided in the installation cavity and connected to the first air inlet channel and the heat dissipation cavity.
[0017] By setting the air inlet channel to include a first air inlet channel provided in the accommodating cavity and connected to the outside world, and a second air inlet channel provided in the installation cavity and connected to the first air inlet channel and the heat dissipation cavity, the outside air first enters the first air inlet channel and effectively dissipates the heat of the power board in the first air inlet channel, thereby reducing the temperature rise of the power board, and then enters the heat dissipation cavity through the second air inlet channel to dissipate the heat of the motor body, thereby ensuring effective heat dissipation of the brushless motor and the power board.
[0018] In a preferred implementation of a food processor with good heat dissipation effect, the first air inlet duct includes a first main unit air inlet provided on the bottom wall of the main unit housing and a first main unit air outlet provided on the side wall of the accommodating groove, and the second air inlet duct includes a cup holder air inlet provided on the side wall of the cup holder, and the first main unit air outlet and the cup holder air inlet at least partially overlap in the horizontal direction; or,
[0019] The first air inlet duct includes a first main unit air inlet provided on the bottom wall of the main unit shell and a first main unit air outlet provided on the bottom wall of the accommodating groove. The second air inlet duct includes a cup holder air inlet provided on the bottom wall of the cup holder. The first main unit air outlet and the cup holder air inlet at least partially overlap in the vertical direction.
[0020] By arranging the first main unit air outlet and the cup holder air inlet to at least partially overlap in the horizontal direction, the airflow entering the first air inlet duct can, after moving upward and dissipating heat to the power board, flow directly horizontally to the cup holder air inlet through the first main unit air outlet, and enter the heat dissipation cavity to dissipate heat to the brushless motor, making the gas flow path smoother, thereby increasing the airflow rate, so that the airflow passing through the power board and the brushless motor per unit time is greater, thereby further improving the heat dissipation efficiency.
[0021] In a preferred implementation of a food processor with good heat dissipation effect, the air outlet channel includes a first air outlet channel provided in the installation cavity and connected to the heat dissipation cavity, and a second air outlet channel provided in the main body shell and connected to the first air outlet channel and the outside.

[0023] In a preferred implementation of a food processor with good heat dissipation effect, the second air outlet includes a second main unit air inlet provided on the bottom wall of the accommodating tank and a second main unit air outlet provided on the bottom wall of the main unit housing, and the first air outlet includes a cup holder air outlet provided on the bottom wall of the cup holder and vertically aligned with the second main unit air inlet; or,
[0024] The second air outlet includes a second host air inlet provided on the side wall of the receiving tank and a second host air outlet provided on the outer wall of the host shell. The first air outlet includes a cup holder air outlet provided on the side wall of the cup holder and laterally aligned with the second host air inlet.
[0025] By setting the second air outlet to include a second main unit air inlet provided on the bottom wall of the accommodating groove and a second main unit air outlet provided on the bottom wall of the main unit shell, the first air outlet includes a cup holder air outlet provided on the bottom wall of the cup holder and vertically aligned with the second main unit air inlet, so that the airflow after heat dissipation of the motor body can be directly discharged downward through the second main unit air outlet. Compared with the existing method of setting the air outlet on the side, it effectively avoids the situation where hot air blows directly to the user, thereby improving the user experience.
[0026] In a preferred implementation of a food processor with good heat dissipation effect, an ipm module is provided on the power board, the ipm module is covered with heat dissipation fins, and an air guide cover is also provided in the accommodating cavity and is arranged above the heat dissipation fins.
[0027] By providing an air guide cover above the heat dissipating fins in the accommodating cavity, the air flow entering the accommodating cavity can be guided by the air guide cover, so that more air flow passes through the heat dissipating fins, thereby achieving effective heat dissipation of the heat dissipating fins, further improving the heat dissipation effect, and avoiding the air flow entering the accommodating cavity from dispersing, resulting in less air flow flowing through the heat dissipating fins and causing poor heat dissipation effect.

DETAILED DESCRIPTION
[0037] 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.
[0038] It should be noted that many specific details are set forth 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 scope of protection of the present invention is not limited to the specific implementation methods disclosed below.
[0039] like Figures 1 to 4As shown, the utility model provides a food processing machine with good heat dissipation effect, including a main unit 2 and a cup body assembly 1 detachably arranged on the main unit 2, the cup body assembly 1 including a cup body 11, a brushless motor 6 arranged below the cup body 11 and a cup seat 12 fixedly connected to the bottom of the cup body 11, the cup seat 12 and the cup body 11 enclose a mounting cavity 121 for accommodating the brushless motor 6, the main unit 2 includes a main unit shell 21, the top of the main unit shell 21 is concave to form a receiving groove for accommodating the cup body assembly 1, and an accommodating cavity 112 is also formed in the main unit shell 21 at the front side of the receiving groove, a power supply board 3 is provided in the accommodating cavity 112, which cooperates with the brushless motor 6 and is placed vertically, the power supply board 3 and the brushless motor 6 at least partially overlap in the horizontal direction, and the accommodating cavity 112 and the mounting cavity 121 are provided with a heat dissipation channel that is interconnected, and the power supply board 3 is arranged upstream of the gas flow path of the brushless motor 6 in the heat dissipation channel.
[0040] The present application sets a brushless motor 6 in the food processor. With the help of the characteristics of the brushless motor 6, when the user uses the food processor to process food, the noise of the motor rotation is lower, thereby achieving the effect of noise reduction. At the same time, the brushless motor 6 can realize variable frequency control, so that the food processor can control the brushless motor 6 to output different speeds according to different food ingredients and processing processes, which can make the processing effect of food ingredients better and more complete, and improve the taste of the food output. In addition, the brushless motor 6 occupies a small space, which helps to improve the compactness of the internal structure of the whole machine and greatly reduces the axial size of the brushless motor 6 and the cup body 11.
[0041] At the same time, the top of the main body housing 21 is recessed to form a receiving groove for accommodating the cup body assembly 1. This allows the cup body assembly 1 to be effectively positioned by the receiving groove after being installed on the main body 2, thereby improving the stability of the connection between the cup body assembly 1 and the main body 2, thereby preventing the cup body assembly 1 from swinging significantly during food processing, thereby preventing noise or even interruption of food processing. It should be noted that the aforementioned receiving groove can limit the position of the cup body assembly 1 by limiting the position of the cup holder 12 or a portion of the cup body 11, and does not require that the entire cup body assembly 1 be placed in the receiving groove. Furthermore, a receiving cavity 112 is formed in the main body housing 21, located in front of the receiving groove. A power board 3 is provided in the receiving cavity 112, which cooperates with the brushless motor 6 and is placed vertically. The power board 3 and the brushless motor 6 at least partially overlap in the horizontal direction, effectively utilizing the horizontal space in the main body 2. Compared with the existing method of arranging the receiving cavity 112 below the receiving groove, the axial dimension of the main body 2 can be further compressed, thereby reducing the center of gravity height of the entire main body 2 and the cup body assembly 1, effectively improving the stability of the entire machine during operation and further improving the stability of the cup body assembly 1 during food processing. At the same time, the contact area between the main body 2 and the desktop can be expanded, thereby further improving the stability of the main body 2.
[0042] In addition, the accommodating cavity 112 and the mounting cavity 121 are provided with heat dissipation channels that are interconnected, so that the brushless motor 6 and the power board 3 can both achieve effective heat dissipation in the heat dissipation channels, which can effectively reduce the temperature rise of the brushless motor 6 and the power board 3, and avoid the situation where the temperature rise of the brushless motor 6 and the power board 3 is obvious, resulting in accelerated aging. In this way, the brushless motor 6 and the power board 3 are electrically connected while achieving synchronous heat dissipation of the two, thereby achieving reliable control and heat dissipation of the entire machine.
[0043] In addition, the power board 3 is arranged upstream of the brushless motor 6 in the gas flow path of the heat dissipation channel, that is, the airflow can first cool the power board 3 and then dissipate the heat of the brushless motor 6, so that the airflow with a lower temperature can dissipate the heat of the power board 3, increase the temperature difference between the airflow and the power board 3, and then improve the heat dissipation effect of the power board 3, further reduce the temperature rise of the power board 3, and at the same time, after completing the cooling of the power board 3, the airflow will pass through the brushless motor 6 again to dissipate the heat of the brushless motor 6, avoiding the brushless motor 6 being located upstream of the power board 3, resulting in the airflow entering the heat dissipation channel having to pass through the brushless motor 6 first and then through the power board 3, resulting in the airflow with a temperature rise after passing through the brushless motor 6 having a small temperature difference with the power board 3 when passing through the power board 3, resulting in a poor heat dissipation effect on the power board 3, thereby ensuring the heat dissipation effect of the brushless motor 6 and the power board 3.
[0044] It should be noted that the top of the main body shell 21 in this application is concave to form a receiving groove for receiving the cup body assembly 1.

[0046] By also vertically placing the control board 5 within the accommodating cavity 112, the space within the main unit 2 is further rationally utilized. Furthermore, the control board 5's location within the accommodating cavity 112 allows airflow through the accommodating cavity 112 to pass not only through the power board 3 but also through the control board 5, thereby dissipating heat from the control board 5 and further improving the overall heat dissipation of the device. Furthermore, the control board 5's location in front of the power board 3 ensures that the user can touch the control board 5 from the front of the main unit 2, enhancing the user experience.
[0047] It should be noted that the present application does not specifically limit the installation method of the control board 5 and the power board 3. As a preferred embodiment of the present application, Figure 2 As shown, a mounting bracket 4 is further provided in the accommodating cavity 112 , and the power board 3 and the control board 5 are fixed on opposite sides of the mounting bracket 4 .
[0048] By providing a mounting bracket 4 in the accommodating cavity 112, and fixing the power board 3 and the control board 5 on opposite sides of the mounting bracket 4, on the one hand, the power board 3 and the control board 5 can be installed and fixed by a single mounting bracket 4, thereby realizing functional integration of the mounting bracket 4, and helping to improve the compactness of the structure within the host 2 and reduce the space occupied by the entire machine; on the other hand, the power board 3 and the control board 5 can be isolated by the mounting bracket 4, effectively reducing the transfer of heat from the power board 3 to the control board 5, avoiding the situation where the temperature rise of the control board 5 is obvious and the aging of the control board 5 is accelerated, and helping to extend the service life of the control board 5.

At the same time, the hot air flow after heat dissipation can be discharged outward through the air outlet channel, realizing a complete heat dissipation path.
[0051] Further, if Figure 3 As shown, the air inlet channel includes a first air inlet channel provided in the accommodating cavity 112 and communicating with the outside, and a second air inlet channel provided in the installation cavity 121 and communicating with the first air inlet channel and the heat dissipation cavity 621 .

[0055] By arranging the first main unit air outlet 23 and the cup holder air inlet 122 to at least partially overlap in the horizontal direction, the airflow entering the first air inlet duct can move upward and dissipate heat to the power board 3, and then flow directly horizontally to the cup holder air inlet 122 through the first main unit air outlet 23, and enter the heat dissipation cavity 621 to dissipate heat to the brushless motor 6, making the gas flow path smoother, thereby increasing the airflow rate, so that the airflow passing through the power board 3 and the brushless motor 6 per unit time is greater, thereby further improving the heat dissipation efficiency.
