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] Existing food processors typically include a base with an internal motor and a detachable grinding cup mounted on the base. The grinding cup contains a grinding device connected to the motor. When using the food processor, the user places the ingredients into the grinding cup, and the grinding device rotates at high speed driven by the motor to process the ingredients. To improve operational stability and reduce noise, a brushless motor is usually chosen. To control the brushless motor components, a power board is essential in the food processor. During operation, the power board, especially its IPM module, generates considerable heat. Since the power board is installed inside the base, airflow through it is limited, causing its temperature to rise rapidly. Continued overheating can lead to overheating and component failure on the power board, thus affecting the performance and reliability of the food processor.

[0003] To address the aforementioned issues, the applicant's earlier patent application CN202320658964.X disclosed a safe and quiet food processing machine employing a brushless motor. This machine places a power board horizontally within a base, which includes a heat dissipation channel communicating with the outside environment. The power board is positioned upstream of the brushless motor in the gas flow path within the heat dissipation channel, allowing airflow to cool the power board first before cooling the brushless motor, thus improving the power board's heat dissipation efficiency. However, to achieve air intake at the bottom wall of the base, this type of machine typically has a larger lateral dimension for the cavity housing the power board, allowing for the formation of an air inlet. This results in an excessively large lateral dimension for the entire machine. If the lateral dimension of the base is reduced, the air inlet would be formed below the power board, causing the power board to at least partially block the air inlet. This obstructs airflow when air enters through the air inlet, significantly reducing the power board's heat dissipation efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a food processing machine with good heat dissipation, so as to solve the problem that in existing food processing machines, the power board used to control the brushless motor is placed horizontally inside the machine base, resulting in a large horizontal dimension of the machine base or the power board blocking the air inlet, causing poor air intake and thus poor heat dissipation of the power board.

[0005] To achieve the above objectives, this utility model provides a food processing machine with good heat dissipation, including a base housing a brushless motor and a detachable grinding cup mounted on the base. The grinding cup contains a grinding device that is driven and connected to the brushless motor. The base includes a first mounting platform and a second mounting platform arranged side by side. The grinding cup is detachably mounted on the first mounting platform. The food processing machine also includes a detachable water tank mounted on the second mounting platform and connected to the grinding cup. The brushless motor is located in the base below the first mounting platform. The food processing machine also includes a power board electrically connected to the brushless motor. The power board is vertically placed in the base below the second mounting platform. The base has a heat dissipation channel communicating with the outside, and the power board is located upstream of the brushless motor in the gas flow path within the heat dissipation channel.

[0006] This application utilizes a brushless motor, leveraging its characteristics to reduce noise during food processing. The brushless motor also allows for variable frequency control, enabling the food processor to adjust its speed based on different ingredients and processing conditions. This results in better and more thorough processing, improving the texture and flavor of the food. Furthermore, the brushless motor occupies less space, contributing to a more compact internal structure and significantly reducing the axial dimensions of the brushless motor relative to the cup body.

[0007] The base includes a first mounting platform and a second mounting platform arranged side by side. The grinding cup is detachably mounted on the first mounting platform, and the water tank is detachably mounted on the second mounting platform and connected to the grinding cup. This allows users to directly supply water to the grinding cup through the water tank while processing food, eliminating the need for manual water supply. It also allows for more precise water filling, improving the accuracy of the food-to-water ratio and thus enhancing the taste of the processed food, making operation more convenient. Furthermore, the power board is vertically placed within the base below the second mounting platform. This design allows the base to accommodate the power board while simultaneously forming the second mounting platform, resulting in a more rational internal space layout, improved space utilization, and reduced lateral space occupation, thereby decreasing the overall horizontal dimensions of the machine. The vertical placement of the power board also creates an air inlet on the bottom wall of the base for effective ventilation, preventing the power board from blocking the air inlet and hindering heat dissipation when placed horizontally.

[0008] Meanwhile, the chassis is equipped with a heat dissipation channel that connects to the outside, and the power board is located upstream of the brushless motor in the airflow path within the heat dissipation channel. This allows the airflow entering the heat dissipation channel to pass through the power board first and then through the brushless motor. In other words, the airflow can cool the power board first and then dissipate heat from the brushless motor. This allows the cooler airflow to dissipate heat from the power board, increasing the temperature difference between the airflow and the power board, thereby improving the heat dissipation effect on the power board and further reducing the temperature rise of the power board. At the same time, the airflow that has cooled the power board will pass through the brushless motor again to dissipate heat from the brushless motor. This avoids the situation where the brushless motor is located upstream of the power board, causing the airflow entering the heat dissipation channel to have to pass through the brushless motor first and then through the power board. This would result in a smaller temperature difference between the airflow that has warmed up after passing through the brushless motor and the power board when passing through the power board, thus reducing the heat dissipation effect on the power board. This ensures the heat dissipation effect of both the brushless motor and the power board. Furthermore, the vertically positioned power board significantly reduces the overall horizontal dimension of the device, thereby greatly shortening the path of airflow in the horizontal direction. This, in turn, shortens the length of the heat dissipation channel, reducing the time the airflow stays within the channel. This increases the airflow rate passing through the power board and brushless motor per unit time, further enhancing the heat dissipation efficiency of both.

[0009] In a preferred embodiment of a food processing machine with good heat dissipation, the base includes a housing, the housing includes a first mounting cavity for accommodating a brushless motor and a second mounting cavity for accommodating a power board, the first mounting cavity and the second mounting cavity are connected, and a heat dissipation channel is formed in the first mounting cavity and the second mounting cavity.

[0010] By configuring the housing to include a first mounting cavity for accommodating the brushless motor and a second mounting cavity for accommodating the power board, the heat generated by the power board is mainly concentrated in the second mounting cavity. This effectively prevents the heat generated by the power board from being directly transferred to the brushless motor, thus avoiding significant temperature rise, severe aging, and reduced lifespan of the brushless motor. This protects the brushless motor. At the same time, the heat dissipation channel is formed in the first and second mounting cavities, allowing the airflow entering the housing to effectively cool the power board after passing through the second mounting cavity before passing through the first mounting cavity to dissipate heat from the brushless motor and then being discharged outwards. This ensures a reasonable gas flow path and helps to improve the efficiency of airflow within the heat dissipation channel, thereby further improving the heat dissipation effect.

[0011] In a preferred embodiment of a food processing machine with good heat dissipation, the front side of the first mounting platform is further provided with an upwardly extending operating part, and the operating part is provided with a third mounting cavity for accommodating the operating panel, and the third mounting cavity is connected to the second mounting cavity.

[0012] By providing an upwardly extending operating section on the front side of the first mounting platform, users can control the food processor by pressing buttons on the operating section, which is more in line with user habits and makes operation more convenient and faster. At the same time, the operating section has a third mounting cavity for accommodating the operating panel, and the third mounting cavity is connected to the second mounting cavity. This allows airflow to pass through the second mounting cavity to dissipate heat from the power board, while some airflow can continue to enter the third mounting cavity to dissipate heat from the operating panel. This helps to maintain a suitable temperature for the operating panel, avoids the impact of high temperature on the stability and lifespan of electronic components, and ensures that the equipment can always operate at its best performance during long-term use.

[0013] In a preferred embodiment of a food processing machine with good heat dissipation, the machine housing is provided with a base air inlet and a base air outlet. The base air inlet is formed in the cavity wall of the second mounting cavity, and the base air outlet is formed in the cavity wall of the first mounting cavity.

[0014] By setting the air inlet of the base to be formed in the cavity wall of the second mounting cavity and the air outlet of the base to be formed in the cavity wall of the first mounting cavity, the external airflow can first enter the second mounting cavity through the air inlet of the base to achieve effective cooling of the power board. At the same time, after entering the first mounting cavity and achieving heat dissipation for the brushless motor, it is discharged outward through the air outlet of the base, ensuring that the airflow in the heat dissipation channel is continuous and smooth, and ensuring the heat dissipation effect.

[0015] In a preferred embodiment of a food processing machine with good heat dissipation, the base includes a housing, the housing has a base air inlet and a base air outlet, and the base also has an air guide shroud connecting the base air inlet and the base air outlet.

[0016] By incorporating an air guide shroud connecting the air inlet and outlet of the chassis, the airflow, after entering the heat dissipation channel, is guided by the shroud to allow more airflow to pass over the power board and brushless motor. This effectively dissipates heat from the power board and brushless motor, further enhancing their cooling performance. It also prevents the airflow from scattering within the heat dissipation channel, resulting in insufficient airflow over the power board and brushless motor and poor cooling. Furthermore, it prevents airflow from wandering around the casing, thus improving airflow efficiency and increasing the airflow rate over the power board and brushless motor per unit time, further enhancing cooling efficiency.

[0017] In a preferred embodiment of a food processing machine with good heat dissipation, the air guide hood is provided with an air outlet connected to the air outlet of the machine base, and multiple noise reduction columns extending vertically are provided at the air outlet of the hood.

[0018] By incorporating multiple vertically extending noise-reducing columns at the air outlet of the enclosure, the airflow can effectively reduce noise as it passes through the air outlet of the enclosure and is discharged to the air outlet of the base. This helps to improve the overall noise reduction effect of the machine, reduce the transmission of noise to the outside world, and enhance the user experience.

[0019] In a preferred embodiment of a food processing machine with good heat dissipation, the air guide shroud includes a first shroud covering the outside of the power board and a second shroud covering the outside of the brushless motor, with the first shroud and the second shroud connected.

[0020] By configuring the air guide shroud as including a first shroud covering the outside of the power board and a second shroud covering the outside of the brushless motor, with the first shroud and the second shroud connected, the airflow, after entering the air guide shroud, first passes through the first shroud to dissipate heat from the power board, and then enters the second shroud to dissipate heat from the brushless motor, ensuring a smooth airflow path. At the same time, the air guide shroud is divided into a first shroud and a second shroud, which facilitates the demolding and production of the air guide shroud and helps to reduce production costs.

[0021] In a preferred embodiment of a food processing machine with good heat dissipation, the second cover is provided with a cover air inlet communicating with the first cover and a cover air outlet communicating with the machine base air outlet, and the cover air inlet and cover air outlet are located on opposite sides of the central axis of the brushless motor.

[0022] By setting the air inlet and outlet of the enclosure to be on opposite sides of the central axis of the brushless motor, the airflow can pass over more of the outer surface of the brushless motor, thereby achieving better heat dissipation and ensuring uniform heat dissipation. This avoids localized overheating of the brushless motor and helps to further improve the heat dissipation effect.

[0023] 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.

[0024] 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.

Detailed Implementation

[0033] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0034] 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.

[0035] like Figures 1 to 5As shown, this utility model provides a food processing machine with good heat dissipation, including a base 1 with a brushless motor 5 inside, a detachable grinding cup 2 on the base 1, a grinding device 4 connected to the brushless motor 5 inside the grinding cup 2, the base 1 including a first mounting platform 11 and a second mounting platform 12 arranged side by side, the grinding cup 2 being detachably mounted on the first mounting platform 11, the food processing machine also including a water tank 3 detachably mounted on the second mounting platform 12 and connected to the grinding cup 2, the brushless motor 5 being located inside the base 1 below the first mounting platform 11, the food processing machine also including a power board 6 electrically connected to the brushless motor 5, the power board 6 being vertically placed inside the base 1 below the second mounting platform 12, the base 1 having a heat dissipation channel connected to the outside, and the power board 6 being located upstream of the brushless motor 5 in the gas flow path within the heat dissipation channel.

[0036] This application incorporates a brushless motor 5, which, by utilizing its characteristics, reduces noise during food processing, thus achieving noise reduction. Furthermore, the brushless motor 5 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 5 occupies less space, contributing to a more compact internal structure and significantly reducing the axial dimensions of the brushless motor 5 relative to the cup body.

[0037] Meanwhile, the base 1 includes a first mounting platform 11 and a second mounting platform 12 arranged side by side. The grinding cup 2 is detachably mounted on the first mounting platform 11, and the water tank 3 is detachably mounted on the second mounting platform 12 and communicates with the grinding cup 2. This allows users to directly supply water to the grinding cup 2 through the water tank 3 when processing food, eliminating the need for manual water supply. It also allows for more precise water injection into the grinding cup 2, improving the accuracy of the food-to-water ratio and thus enhancing the taste of the processed food, making operation more convenient for users. Furthermore, the power board 6 is vertically placed inside the base 1 below the second mounting platform 12. This allows the base 1 to form the second mounting platform 12 while simultaneously accommodating the power board 6, resulting in a more rational internal space arrangement and improved space utilization. It also reduces the horizontal space occupied, thereby reducing the overall horizontal dimensions of the machine. Additionally, the vertical placement of the power board 6 creates an air inlet on the bottom wall of the base 1 for effective ventilation, preventing the power board 6 from blocking the air inlet when placed horizontally, thus avoiding poor airflow and heat dissipation.

[0038] Meanwhile, the base 1 is equipped with a heat dissipation channel that communicates with the outside. The power board 6 is located upstream of the brushless motor 5 in the air flow path within the heat dissipation channel. This allows the airflow entering the heat dissipation channel to pass through the power board 6 first and then through the brushless motor 5. In other words, the airflow can first cool the power board 6 and then dissipate heat from the brushless motor 5. This allows the cooler airflow to dissipate heat from the power board 6, increasing the temperature difference between the airflow and the power board 6, thereby improving the heat dissipation effect of the power board 6 and further reducing the temperature rise of the power board 6. At the same time, the airflow that has finished cooling the power board 6 will pass through the brushless motor 5 again to dissipate heat from the brushless motor 5. This avoids the situation where the brushless motor 5 is located upstream of the power board 6, causing the airflow entering the heat dissipation channel to have to pass through the brushless motor 5 first and then through the power board 6. This would result in a smaller temperature difference between the airflow that has warmed up after passing through the brushless motor 5 and the power board 6 when passing through the power board 6, thus reducing the heat dissipation effect of the power board 6. This ensures the heat dissipation effect of both the brushless motor 5 and the power board 6. Moreover, the vertically positioned power board 6 greatly reduces the horizontal dimension of the entire machine, thereby significantly shortening the path of airflow in the horizontal direction. This, in turn, shortens the length of the heat dissipation channel, reducing the time the airflow stays in the heat dissipation channel. This increases the airflow rate passing through the power board 6 and the brushless motor 5 per unit time, further improving the heat dissipation efficiency of both.

[0039] As a preferred embodiment of this application, such as Figure 2 As shown, the base 1 includes a housing 14, which includes a first mounting cavity 141 for accommodating the brushless motor 5 and a second mounting cavity 142 for accommodating the power board 6. The first mounting cavity 141 and the second mounting cavity 142 are connected, and heat dissipation channels are formed in the first mounting cavity 141 and the second mounting cavity 142.

[0040] By configuring the housing 14 to include a first mounting cavity 141 for accommodating the brushless motor 5 and a second mounting cavity 142 for accommodating the power board 6, the heat generated by the power board 6 is mainly concentrated in the second mounting cavity 142. This effectively prevents the heat generated by the power board 6 from being directly transferred to the brushless motor 5, thus avoiding a significant temperature rise in the brushless motor 5, which would lead to severe aging and a reduced service life. This protects the brushless motor 5. At the same time, the heat dissipation channel is formed in the first mounting cavity 141 and the second mounting cavity 142, so that the airflow entering the housing 14 can effectively cool the power board 6 after passing through the second mounting cavity 142, and then dissipate heat from the brushless motor 5 through the first mounting cavity 141 before being discharged outward. This ensures the rationality of the gas flow path and helps to improve the efficiency of airflow in the heat dissipation channel, thereby further improving the heat dissipation effect.

[0041] Furthermore, such as Figure 1As shown, the front side of the first mounting platform 11 is also provided with an upwardly extending operation part 13. The operation part 13 is provided with a third mounting cavity for accommodating the operation panel, and the third mounting cavity is connected to the second mounting cavity 142.

[0042] By providing an upwardly extending operating section 13 on the front side of the first mounting platform 11, users can control the food processor by pressing buttons on the operating section 13, which is more in line with user habits and makes operation more convenient and faster. At the same time, the operating section 13 has a third mounting cavity for accommodating the operating panel, and the third mounting cavity is connected to the second mounting cavity 142. This allows airflow to cool the power board 6 in the second mounting cavity 142, while some airflow can continue to enter the third mounting cavity to cool the operating panel. This helps to maintain a suitable temperature for the operating panel, avoids the impact of high temperature on the stability and lifespan of electronic components, and ensures that the equipment can always operate at its best performance during long-term use.

[0043] As a preferred embodiment of this implementation, such as Figure 2 , Figure 3 As shown, the housing 14 is provided with a base air inlet 1431 and a base air outlet 1432. The base air inlet 1431 is formed in the cavity wall of the second mounting cavity 142, and the base air outlet 1432 is formed in the cavity wall of the first mounting cavity 141.

[0044] By setting the base air inlet 1431 to be formed in the cavity wall of the second mounting cavity 142 and the base air outlet 1432 to be formed in the cavity wall of the first mounting cavity 141, the external airflow can first enter the second mounting cavity 142 through the base air inlet 1431 to effectively cool the power board 6. At the same time, after entering the first mounting cavity 141 and cooling the brushless motor 5, it is discharged outward through the base air outlet 1432, ensuring that the airflow in the heat dissipation channel is continuous and smooth, and ensuring the heat dissipation effect.

[0045] It should be noted that this application does not specifically limit the forming positions of the air inlet 1431 and the air outlet 1432 of the base. As a preferred embodiment of this application, such as Figure 3 As shown, the housing 14 includes an outer shell with an open bottom and a bottom cover 143 covering the bottom of the outer shell. The air inlet 1431 and the air outlet 1432 of the housing are both formed on the bottom cover 143.

[0046] As a preferred embodiment of this application, such as Figure 3 As shown, the base 1 includes a housing 14, which has a base air inlet 1431 and a base air outlet 1432. The base 1 also has an air guide shroud 7 that connects the base air inlet 1431 and the base air outlet 1432.

[0047] By providing an air guide shroud 7 inside the base 1 that connects the base air inlet 1431 and the base air outlet 1432, the airflow, after entering the heat dissipation channel, is guided by the air guide shroud 7 to allow more airflow to pass through the power board 6 and the brushless motor 5. This achieves effective heat dissipation for the power board 6 and the brushless motor 5, further improving their heat dissipation effect. It also prevents the airflow from scattering in the heat dissipation channel, resulting in less airflow passing through the power board 6 and the brushless motor 5 and thus poor heat dissipation. At the same time, it prevents the airflow from wandering around inside the housing 14, which would lead to low flow efficiency. This helps to improve airflow efficiency, thereby increasing the airflow rate passing through the power board 6 and the brushless motor 5 per unit time, further improving heat dissipation efficiency.

[0048] Furthermore, such as Figure 3 As shown, the air guide shroud 7 is provided with a shroud air outlet 712 that is connected to the air outlet 1432 of the base, and multiple noise reduction columns 713 extending vertically are provided at the shroud air outlet 712.

[0049] By providing multiple vertically extending noise reduction columns 713 at the air outlet 712 of the cover, the airflow can effectively reduce noise as it passes through the air outlet 712 of the cover and is discharged to the air outlet 1432 of the base. This helps to improve the overall noise reduction effect of the machine, reduce the transmission of noise to the outside, and improve the user experience.

[0050] As a preferred embodiment of this implementation, such as Figure 3 As shown, the air guide cover 7 includes a first cover 71 covering the outside of the power board 6 and a second cover 72 covering the outside of the brushless motor 5, with the first cover 71 and the second cover 72 connected.

[0051] By configuring the air guide shroud 7 to include a first cover 71 covering the outside of the power board 6 and a second cover 72 covering the outside of the brushless motor 5, with the first cover 71 and the second cover 72 connected, the airflow, after entering the air guide shroud 7, first passes through the first cover 71 to dissipate heat from the power board 6, and then enters the second cover 72 to dissipate heat from the brushless motor 5, ensuring a smooth airflow path. At the same time, the air guide shroud 7 is divided into a first cover 71 and a second cover 72, which facilitates the demolding and production of the air guide shroud 7 and helps to reduce production costs.

[0052] Furthermore, such as Figure 3 , Figure 5 As shown, the second cover 72 is provided with a cover air inlet 711 that communicates with the first cover 71 and a cover air outlet 712 that communicates with the base air outlet 1432. The cover air inlet 711 and the cover air outlet 712 are located on opposite sides of the central axis of the brushless motor 5.

[0053] By setting the air inlet 711 and air outlet 712 of the cover to be on opposite sides of the central axis of the brushless motor 5, the airflow can pass over more of the outer surface of the brushless motor 5, so as to achieve better heat dissipation of the brushless motor 5 and ensure the uniformity of heat dissipation, avoid local overheating of the brushless motor 5, and help to further improve the heat dissipation effect.

[0054] As a preferred embodiment of this application, such as Figure 5 As shown, the food processing machine also includes a cooling fan 8 located in the heat dissipation channel.

[0055] By installing a cooling fan 8 in the heat dissipation channel, the airflow rate in the heat dissipation channel is further increased by the cooling fan 8, thereby further increasing the airflow rate through the power board 6 and brushless motor 5 per unit time, further improving the heat dissipation effect and reducing the temperature rise of both.
