Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a food processing machine with good heat dissipation. Background Technology

[0002] With social development and improved living standards, people are increasingly pursuing more diverse and healthier diets. As a result, various industrial food processing machines have gradually become smaller and entered households, such as soy milk makers. These machines not only meet people's needs for healthy and nutritious food but also greatly improve their quality of life, thus gaining popularity.

[0003] Existing food processors typically include a main body, a cup containing a grinding chamber, a grinding device within the grinding chamber, and a motor located at the bottom of the cup and connected to the grinding device. When using the food processor, the user places ingredients into the cup, and the motor drives the grinding device to rotate at high speed to process the ingredients. To improve operational stability and reduce noise, a brushless motor is usually chosen. Furthermore, to control the brushless motor and other components, a power board is essential in the food processor. For example, the applicant's earlier patent application CN202322302917.4 discloses a food processor with good heat dissipation. This type of food processor has a large main body with sufficient internal space for heat dissipation of various components. However, in actual products such as ordinary blenders and small blenders, the internal space is very limited, which affects the heat dissipation of the brushless motor and other components. The heat dissipation effect of the components is relatively poor. Brushless motors typically consist of a housing with a mounting cavity and a motor body located within the mounting cavity. The heat generated by the motor body during high-speed rotation cannot be effectively dissipated from the mounting cavity, resulting in a significant temperature rise in the entire brushless motor. In contrast, the power board is directly exposed inside the housing of the machine body, allowing the generated heat to be directly transferred to the outside, thus achieving a better heat dissipation effect. Therefore, the temperature rise of the brushless motor is relatively higher than that of the power board. Continuous temperature rise may cause the brushless motor to age severely due to overheating, thereby affecting the performance of the food processing machine and reducing its operational reliability. Utility Model Content

[0004] The purpose of this invention is to provide a food processing machine with good heat dissipation, in order to solve the problem that in the case of existing food processing machines with compact structure to save space, the internal heat dissipation efficiency is low, which leads to the inability to dissipate the heat generated by the brushless motor in time, causing it to overheat and age severely.

[0005] To achieve the above objectives, this utility model provides a food processor with good heat dissipation, including a cup body with a grinding chamber, a grinding device disposed in the grinding chamber, and a brushless motor disposed below the cup body and drivenly connected to the grinding device. The food processor also includes a power board that cooperates with the brushless motor. The food processor is also provided with a heat dissipation channel communicating with the outside. The power board and the brushless motor are both located in the heat dissipation channel, and the brushless motor is located upstream of the power board in the gas flow path in the heat dissipation channel, so that the airflow in the heat dissipation channel passes through the brushless motor first and then through the power board.

[0006] This application incorporates a brushless motor within a food processor. Leveraging the characteristics of brushless motors, the noise level during food processing is significantly reduced, achieving noise reduction. Furthermore, the brushless motor's variable frequency control allows the food processor to adjust its output speed according to different ingredients and processing conditions, resulting in better and more thorough processing, improved texture, and a smaller footprint. This contributes to a more compact internal structure and significantly reduces the axial dimensions of the brushless motor relative to the cup body.

[0007] Meanwhile, the food processor is also equipped with a heat dissipation channel that connects to the outside world. The power board and brushless motor are both located in the heat dissipation channel, which allows the brushless motor and power board to effectively dissipate heat within the channel. This effectively reduces the temperature rise of the brushless motor and power board, preventing them from aging faster due to significant temperature increases.

[0008] Brushless motors typically consist of a housing with a mounting cavity and a motor body located within the mounting cavity. During high-speed rotation, the heat generated by the motor body cannot dissipate effectively within the mounting cavity, leading to a significant temperature rise in the entire brushless motor. In contrast, the power board is directly exposed inside the food processor, allowing for direct heat dissipation. Therefore, the temperature rise of the brushless motor is relatively higher than that of the power board. By positioning the brushless motor upstream of the power board in the airflow path within the heat dissipation channel, the airflow passes through the brushless motor first and then the power board. This allows the airflow to cool the brushless motor first, and then the power board, increasing the temperature difference between the airflow and the brushless motor, thus improving the heat dissipation effect and further reducing the temperature rise of the brushless motor. After cooling the brushless motor, the airflow then passes back to the power board for further cooling. For traditional blenders, this design achieves efficient heat dissipation for components such as the brushless motor and power board while maintaining a compact design. To avoid the power board being located upstream of the brushless motor, which would force the airflow entering the heat dissipation channel to pass through the power board before passing through the brushless motor, resulting in a smaller temperature difference between the airflow that has heated up after passing through the power board and the brushless motor, thus reducing the heat dissipation effect on the brushless motor, it is necessary to ensure the heat dissipation effect of the brushless motor.

[0009] In a preferred embodiment of a food processing machine with good heat dissipation, the food processing machine also includes a cooling fan disposed within a heat dissipation channel.

[0010] By installing a cooling fan in the heat dissipation channel, the airflow rate in the heat dissipation channel is further increased by the cooling fan, thereby further increasing the airflow rate through the power board and brushless motor per unit time, further improving the heat dissipation effect and reducing the temperature rise of both.

[0011] In a preferred embodiment of a food processing machine with good heat dissipation, the cooling fan is located on the side close to the brushless motor.

[0012] By placing the cooling fan closer to the brushless motor, the fan can prioritize driving the airflow near the brushless motor when it rotates. This makes the airflow near the brushless motor more concentrated and faster, which helps to further increase the airflow rate near the brushless motor per unit time. This, in turn, further improves the cooling effect on the brushless motor and avoids the situation where the airflow is too far from the cooling fan, resulting in a smaller airflow rate at the brushless motor due to multiple airflow directions.

[0013] In a preferred embodiment of a food processing machine with good heat dissipation, the brushless motor includes a housing having a mounting cavity and a motor body disposed within the mounting cavity, with a cooling fan disposed within the mounting cavity.

[0014] By placing the cooling fan within the mounting cavity, and ideally, connecting it to the motor body via a drive mechanism, the brushless motor can synchronously drive the cooling fan as it rotates. This eliminates the need for a separate motor to drive the cooling fan, simplifying the overall structure and improving its compactness. Furthermore, placing the cooling fan within the mounting cavity allows it to directly drive airflow near the motor body, directly dissipating heat and further enhancing cooling efficiency.

[0015] In a preferred embodiment of a food processing machine with good heat dissipation, the heat dissipation channel includes a first heat dissipation channel with a built-in brushless motor and a second heat dissipation channel with a built-in power board, and the airflow direction in the first heat dissipation channel and the second heat dissipation channel is the same.

[0016] By setting the airflow direction in the first and second heat dissipation channels to be the same, the airflow dissipates heat from the brushless motor in the first heat dissipation channel before entering the second heat dissipation channel to dissipate heat from the power board. Furthermore, the airflow does not bend when switching between different heat dissipation channels due to different flow directions. This reduces the risk of airflow velocity reduction caused by collisions with the inner wall of the heat dissipation channel during bends, which could lead to a decrease in airflow velocity and consequently a deterioration in the heat dissipation effect on the brushless motor and power board. This helps to ensure the airflow rate and thus guarantee the heat dissipation efficiency for the brushless motor and power board.

[0017] In a preferred embodiment of a food processing machine with good heat dissipation, the power board is located below the brushless motor. The brushless motor includes a housing with a mounting cavity and a motor body disposed within the mounting cavity. A first heat dissipation channel is formed within the mounting cavity. The top wall and bottom wall of the housing are respectively provided with a motor air inlet and a motor air outlet; or...

[0018] The power supply board is arranged side by side on the outside of the brushless motor. The brushless motor includes a housing with a mounting cavity and a motor body located in the mounting cavity. The first heat dissipation channel is formed in the mounting cavity. The side walls on opposite sides of the housing are respectively provided with a motor air inlet and a motor air outlet.

[0019] By placing the power board below the brushless motor and forming the first heat dissipation channel within the mounting cavity, with the top and bottom walls of the housing respectively providing a motor air inlet and a motor air outlet, the airflow, after entering the heat dissipation channel, first passes through the motor air inlet into the mounting cavity, thus effectively dissipating heat from the motor body. After dissipating heat from the motor body, the airflow then flows downwards through the motor air outlet to the vicinity of the power board, effectively dissipating heat from the power board. This achieves top-to-bottom heat dissipation within the heat dissipation channel, and the use of gravity further enhances the efficiency of airflow, contributing to further improving the heat dissipation efficiency for both the brushless motor and the power board.

[0020] In a preferred embodiment of a food processing machine with good heat dissipation, the heat dissipation channel includes a first heat dissipation channel with a built-in brushless motor and a second heat dissipation channel with a built-in power board, wherein the first heat dissipation channel is bent relative to the second heat dissipation channel.

[0021] By setting the first heat dissipation channel to be bent relative to the second heat dissipation channel, the airflow enters the first heat dissipation channel to dissipate heat from the brushless motor, and then bends before entering the second heat dissipation channel to dissipate heat from the power board. During the bending process, the airflow can pass through more other structural components, thereby dissipating heat from more components in the food processing machine, which helps to further reduce the temperature rise of the entire machine.

[0022] In a preferred embodiment of a food processor with good heat dissipation, the food processor further includes an air guide shroud covering the outside of the power board.

[0023] By setting up an air guide shroud on the outside of the power board, the airflow entering the heat dissipation channel can be guided by the air guide shroud, allowing more airflow to pass through the power board, thereby achieving effective heat dissipation of the power board and further improving its heat dissipation effect. This avoids the situation where the airflow entering the heat dissipation channel disperses, resulting in less airflow passing through the power board and thus poor heat dissipation effect.

Detailed Implementation

[0030] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0031] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may 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 embodiments disclosed below.

[0032] like Figures 1 to 3 As shown, this utility model provides a food processor with good heat dissipation, including a cup body 1 with a grinding chamber 11, a grinding device 4 disposed in the grinding chamber 11, and a brushless motor 6 disposed below the cup body 1 and drivenly connected to the grinding device 4. The food processor also includes a power board 3 that cooperates with the brushless motor 6. The food processor is also provided with a heat dissipation channel communicating with the outside. The power board 3 and the brushless motor 6 are both located in the heat dissipation channel, and the brushless motor 6 is located upstream of the power board 3 in the gas flow path in the heat dissipation channel, so that the airflow in the heat dissipation channel passes through the brushless motor 6 first and then through the power board 3. It should be noted that this application does not specifically limit the structure of the food processor. It can be a main unit 2 including a built-in brushless motor 6, with the cup body 1 detachably disposed on the main unit 2; or it can include a machine body, a cup body 1, and a brushless motor 6 disposed in the machine body, which will not be described in detail here.

[0033] This application incorporates a brushless motor 6 within a food processor. Utilizing the characteristics of the brushless motor 6, the noise level during food processing is reduced, achieving noise reduction. Furthermore, the brushless motor 6 is capable of frequency conversion control, allowing the food processor to adjust its output speed according to different ingredients and processing conditions. This results in better and more thorough processing, enhancing the texture and flavor of the food. Additionally, the brushless motor 6 occupies less space, contributing to a more compact internal structure and significantly reducing the axial dimensions of the brushless motor 6 relative to the cup body 1.

[0034] Meanwhile, the food processing machine is also equipped with a heat dissipation channel that connects to the outside world. The power board 3 and the brushless motor 6 are both located in the heat dissipation channel, which enables the brushless motor 6 and the power board 3 to effectively dissipate heat within the heat dissipation channel. This effectively reduces the temperature rise of the brushless motor 6 and the power board 3, and avoids the situation where the temperature rise of the brushless motor 6 and the power board 3 is significant, leading to accelerated aging.

[0035] The brushless motor 6 typically includes a housing 62 with a mounting cavity 621 and a motor body 61 disposed within the mounting cavity 621. During high-speed rotation, the heat generated by the motor body 61 cannot be effectively dissipated from the mounting cavity 621, resulting in a significant temperature rise in the entire brushless motor 6. In contrast, the power board 3 is directly exposed inside the food processor, allowing for direct heat transfer to the outside, thus achieving better heat dissipation. Therefore, the temperature rise of the brushless motor 6 is relatively higher than that of the power board 3. By positioning the brushless motor 6 upstream of the power board 3 in the gas flow path within the heat dissipation channel, the temperature rise can be reduced. The airflow within the heat dissipation channel first passes through the brushless motor 6 and then through the power board 3. This means the airflow first cools the brushless motor 6 and then the power board 3, allowing the cooler airflow to effectively dissipate heat from the brushless motor 6. This increases the temperature difference between the airflow and the brushless motor 6, thereby improving the heat dissipation effect and further reducing the temperature rise of the brushless motor 6. After cooling the brushless motor 6, the airflow then passes back to the power board 3 for heat dissipation. For a traditional blender, this design achieves efficient heat dissipation for components like the brushless motor 6 and the power board 3 while maintaining a compact design. This avoids the situation where the power board 3 is located upstream of the brushless motor 6, forcing the airflow to pass through it before reaching the brushless motor 6. This would result in a smaller temperature difference between the warmer airflow and the brushless motor 6, leading to poorer heat dissipation. Therefore, this design ensures effective heat dissipation for the brushless motor 6.

[0036] As a preferred embodiment of this application, such as Figure 2 As shown, the food processing machine also includes a cooling fan 7 located in the heat dissipation channel.

[0037] By installing a cooling fan 7 in the heat dissipation channel, the airflow rate in the heat dissipation channel is further increased by the cooling fan 7, thereby further increasing the airflow rate through the power board 3 and the brushless motor 6 per unit time, further improving the heat dissipation effect and reducing the temperature rise of both.

[0038] It should be noted that this application does not specifically limit the location of the cooling fan 7, which can be any of the following embodiments:

[0039] Example 1: As Figure 2 As shown, in this embodiment, the cooling fan 7 is located on the side close to the brushless motor 6.

[0040] By placing the cooling fan 7 on the side close to the brushless motor 6, the cooling fan 7 can prioritize driving the airflow near the brushless motor 6 when it rotates. This makes the airflow near the brushless motor 6 more concentrated and faster, which helps to further increase the airflow rate near the brushless motor 6 per unit time, thereby further improving the heat dissipation effect on the brushless motor 6. This avoids the situation where the airflow is too far from the cooling fan 7, resulting in airflow flowing to the cooling fan 7 in multiple directions and causing a small airflow rate at the brushless motor 6.

[0041] As a preferred embodiment, such as Figure 2 As shown, the brushless motor 6 includes a housing 62 with a mounting cavity 621 and a motor body 61 disposed in the mounting cavity 621. It should be further noted that this application does not specifically limit the location of the cooling fan 7 in this embodiment, and the cooling fan 7 is disposed in the mounting cavity 621.

[0042] More preferably, by placing the cooling fan 7 within the mounting cavity 621, such as... Figure 2 As shown, the cooling fan 7 is connected to the motor body 61 via a transmission, allowing the brushless motor 6 to synchronously drive the cooling fan 7 to rotate when it rotates. This eliminates the need for a separate motor to drive the cooling fan 7, simplifying the overall structure and improving its compactness. Furthermore, the cooling fan 7 is located within the mounting cavity 621, allowing it to directly drive airflow near the motor body 61 during rotation, thus directly cooling the motor body 61 and further improving heat dissipation efficiency.

[0043] Of course, the cooling fan 7 is not limited to being installed in the mounting cavity 621. It can also be installed at the bottom of the housing 62. The motor shaft of the motor body 61 passes through the bottom wall of the housing 62 and is connected to the cooling fan 7. This will not be elaborated further here.

[0044] Example 2: In this example, the cooling fan 7 is located between the brushless motor 6 and the power board 3. Preferably, the food processing machine also includes a drive motor, which is connected to the cooling fan 7 to achieve the rotation of the cooling fan 7.

[0045] In a preferred embodiment of this application, the heat dissipation channel includes a first heat dissipation channel 622 housing the brushless motor 6 and a second heat dissipation channel 21 housing the power board 3. It should be noted that this application does not specifically limit the relative relationship between the first heat dissipation channel 622 and the second heat dissipation channel 21, which can be any of the following embodiments:

[0046] Example 1: As Figure 3As shown, in this embodiment, the airflow direction in the first heat dissipation channel 622 and the second heat dissipation channel 21 is the same.

[0047] By setting the airflow direction in the first heat dissipation channel 622 and the second heat dissipation channel 21 to be in the same direction, the airflow can dissipate heat from the brushless motor 6 after passing through the first heat dissipation channel 622, and then enter the second heat dissipation channel 21 to dissipate heat from the power board 3. Furthermore, the airflow will not bend due to different flow directions when switching between different heat dissipation channels, thereby reducing the possibility of the airflow velocity decreasing due to collision with the inner wall of the heat dissipation channel when turning, which would lead to a decrease in airflow velocity and thus a deterioration in the heat dissipation effect on the brushless motor 6 and the power board 3. This helps to ensure the airflow rate and thus ensure the heat dissipation efficiency of the brushless motor 6 and the power board 3.

[0048] It should be further noted that this application does not specifically limit the arrangement position of the brushless motor 6 and the power board 3 in this embodiment, and it can be any of the following embodiments:

[0049] Implementation Method 1: In this implementation method, the power board 3 is located below the brushless motor 6. The brushless motor 6 includes a housing 62 with a mounting cavity 621 and a motor body 61 located in the mounting cavity 621. The first heat dissipation channel 622 is formed in the mounting cavity 621. The top wall and bottom wall of the housing 62 are respectively provided with a motor air inlet 623 and a motor air outlet 624.

[0050] By placing the power board 3 below the brushless motor 6 and forming the first heat dissipation channel 622 within the mounting cavity 621, and providing a motor air inlet 623 and a motor air outlet 624 on the top and bottom walls of the housing 62 respectively, the airflow, after entering the heat dissipation channel, first passes through the motor air inlet 623 into the mounting cavity 621, thereby effectively dissipating heat from the motor body 61. After dissipating heat from the motor body 61, the airflow then flows downwards through the motor air outlet 624 to the vicinity of the power board 3, thereby effectively dissipating heat from the power board 3. This achieves top-to-bottom heat dissipation within the heat dissipation channel, and the efficiency of airflow can also be improved by gravity, which helps to further improve the heat dissipation efficiency of the brushless motor 6 and the power board 3.

[0051] Implementation method 2: such as Figure 3 As shown, in this embodiment, the power board 3 is arranged side by side on the outside of the brushless motor 6. The brushless motor 6 includes a housing 62 with a mounting cavity 621 and a motor body 61 disposed in the mounting cavity 621. The first heat dissipation channel 622 is formed in the mounting cavity 621. The side walls on opposite sides of the housing 62 are respectively provided with a motor air inlet 623 and a motor air outlet 624.

[0052] Example 2: Figure 2As shown, in this embodiment, the first heat dissipation channel 622 is bent relative to the second heat dissipation channel 21.

[0053] By setting the first heat dissipation channel 622 to be bent relative to the second heat dissipation channel 21, the airflow enters the first heat dissipation channel 622 to dissipate heat from the brushless motor 6, and then bends before entering the second heat dissipation channel 21 to dissipate heat from the power board 3. During the bending process, the airflow can pass through more other structural components, thereby dissipating heat from more components in the food processing machine, which helps to further reduce the temperature rise of the whole machine.

[0054] Furthermore, this application does not specifically limit the placement of the brushless motor 6 and the power board 3 in this embodiment, and it can be any of the following embodiments:

[0055] Implementation Method 1: In this implementation method, the power board 3 is located below the brushless motor 6. The brushless motor 6 includes a housing 62 with a mounting cavity 621 and a motor body 61 located within the mounting cavity 621. A first heat dissipation channel 622 is formed within the mounting cavity 621. The side walls on opposite sides of the housing 62 are respectively provided with a motor air inlet 623 and a motor air outlet 624. Specifically, after the airflow enters the heat dissipation channel, it enters the mounting cavity 621 through the motor air inlet 623 to dissipate heat from the motor body 61, and then exits the mounting cavity 621 through the motor air outlet 624. The airflow then bends downward and flows to the vicinity of the power board 3 to dissipate heat from the power board 3.

[0056] Implementation Method 2: In this implementation method, the power board 3 is arranged side-by-side outside the brushless motor 6. The brushless motor 6 includes a housing 62 with a mounting cavity 621 and a motor body 61 disposed within the mounting cavity 621. A first heat dissipation channel 622 is formed within the mounting cavity 621. The top wall and bottom wall of the housing 62 are respectively provided with a motor air inlet 623 and a motor air outlet 624. Specifically, after the airflow enters the heat dissipation channel, it enters the mounting cavity 621 through the motor air inlet 623 to dissipate heat from the motor body 61, and then exits the mounting cavity 621 through the motor air outlet 624. The airflow then bends upward and flows to the vicinity of the power board 3 to dissipate heat from the power board 3.

[0057] As a preferred embodiment of this application, such as Figure 2 , Figure 3 As shown, the food processing machine also includes an air guide shroud 5 covering the outside of the power board 3.

[0058] By setting an air guide shroud 5 on the outside of the power board 3, the airflow entering the heat dissipation channel can be guided by the air guide shroud 5, so that more airflow passes through the power board 3, thereby achieving effective heat dissipation of the power board 3 and further improving its heat dissipation effect. This avoids the situation where the airflow entering the heat dissipation channel disperses and causes less airflow to pass through the power board 3, resulting in poor heat dissipation.

It should be noted that any combination of the technical solutions of any embodiment with one or more other embodiments is within the protection scope of this utility model. Although this utility model has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art.
