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 fixed to the bottom of the cup. When using the food processor, a user places food into the cup, and the motor drives the grinding mechanism to rotate at high speed to process the food. To improve operational stability and reduce noise, brushless motors are often used. During high-speed rotation, brushless motors drive air flow within the cup holder, particularly near the motor, dissipating heat from the motor. However, brushless motors generate relatively little heat during operation. To control the motor and other components, food processors must include a circuit board (PCB) to control the motor and other components. The operating temperature of the electronic components on the PCB directly determines their service life and stability. During operation, the PCB, particularly the IPM module, generates significant heat. Furthermore, the PCB is typically mounted within the main unit, where airflow through the PCB is limited, causing the PCB's temperature to rise rapidly. This continued heating can cause components on the PCB to fail due to overheating, thereby impacting the performance and reliability of the food processor. Utility Model Content

[0003] The purpose of the utility model is to provide a food processing machine with good heat dissipation effect, so as to solve the problem that the airflow passing through the circuit board in the existing food processing machine is small, resulting in low heat dissipation efficiency of the circuit board and causing the circuit board to be easily overheated and fail.

[0004] To achieve the above-mentioned purpose, the utility model provides a food processing machine with good heat dissipation effect, including a main unit and a detachable cup body assembly arranged on the main unit, the cup body assembly including a cup body and a brushless motor arranged below the cup body, the main unit including a main unit housing and an IPM module arranged in the main unit housing and cooperating with the brushless motor, the main unit housing is provided with an inwardly recessed grip position, the grip position is provided with an air inlet, and the IPM module is arranged above the air inlet.

[0005] The present application uses a brushless motor and takes advantage of the characteristics of the brushless motor to enable users to use the food processor to process food with lower motor rotation noise, thereby achieving noise reduction. At the same time, the brushless motor can achieve 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 output. In addition, the brushless motor occupies less space, which helps to improve the compactness of the internal structure of the entire machine, reduce the space occupied by the food processor, and facilitate storage by users.

[0006] At the same time, the main body shell is provided with an inwardly recessed grip, so that the user can put his hand into the grip to pick up the food processor when using it, which makes it more convenient and quick for the user to pick up the food processor, thereby improving the user experience. In addition, an air inlet is provided on the grip, so that the outside air can enter the main body through the air inlet, thereby effectively dissipating the heat of the various components in the main body. At the same time, the grip can also take in air while being combined with the grip, thus achieving functional integration and eliminating the need to set up air inlets in other parts, thereby improving space utilization and ensuring the consistency of the main body appearance. In addition, the IPM module is provided above the air inlet, so that the airflow entering the main body through the air inlet can directly dissipate heat for the IPM module, which can effectively reduce the temperature rise of the IPM module and avoid the situation where the temperature rise of the IPM module significantly leads to accelerated aging, thereby greatly improving the heat dissipation effect and reliability of the IPM module and helping to increase the service life of the IPM module.

[0007] In a preferred implementation of a food processing machine with good heat dissipation effect, an air guide cover is provided in the main housing and is located above the IPM module. The air guide cover and the IPM module cooperate to form a heat dissipation cavity. The main housing is also provided with an air outlet, and the heat dissipation cavity connects the air inlet and the air outlet.

[0008] By providing an air guide cover above the IPM module in the main housing, the air guide cover and the IPM module cooperate to form a heat dissipation cavity, so that the airflow entering the main housing can enter the heat dissipation cavity through the guidance of the air guide cover, so that more airflow passes through the IPM module, thereby achieving effective heat dissipation of the main heat-generating component IPM module, further improving its heat dissipation effect, and avoiding the airflow entering the main housing through the air inlet from being scattered, resulting in less airflow flowing through the IPM module and causing its heat dissipation effect to be poor. At the same time, the main housing is also provided with an air outlet, and the heat dissipation cavity connects the air inlet and the air outlet, so that the air guide cover connects the air inlet and the air outlet, so that the heat dissipation airflow path in the main housing is air inlet-heat dissipation cavity-air outlet, thereby achieving maximum heat dissipation efficiency for the IPM module, which helps to further improve the heat dissipation effect.

[0009] In a preferred implementation of a food processing machine with good heat dissipation effect, the food processing machine also includes a circuit board, the IPM module is integrated on the circuit board, the circuit board includes a low-temperature zone and a high-temperature zone with the IPM module, and the air guide cover is provided with a partition isolating between the low-temperature zone and the high-temperature zone to separate the heat dissipation cavity into a first cavity with a low-temperature zone and a second cavity with a high-temperature zone.

[0010] By providing a partition between the low-temperature zone and the high-temperature zone on the air guide cover, the heat dissipation cavity is divided into a first cavity with a low-temperature zone and a second cavity with a high-temperature zone, so that the high-temperature zone and the low-temperature zone are isolated from each other by the partition, effectively avoiding the high-temperature heat in the high-temperature zone from being conducted to electrical components in the low-temperature zone, such as pre-charging resistors and relays, which can reduce the temperature rise of electrical components in the low-temperature zone and help improve the heat dissipation effect.

[0011] In a preferred implementation of a food processor with good heat dissipation effect, the gripping position includes a first gripping position and a second gripping position, the air inlet includes a first air inlet and a second air inlet provided on the first gripping position and the second gripping position, and the first air inlet and the second air inlet are respectively connected to the first cavity and the second cavity; or,

[0012] The partition is provided with a ventilation hole connecting the first cavity and the second cavity. The air inlet is located close to the first cavity, and the air outlet is close to the second cavity, so that the air flow passes through the first cavity and then the second cavity and is discharged from the air outlet.

[0013] By setting the gripping position to include a first gripping position and a second gripping position, the user can use both hands to reach into the first gripping position and the second gripping position at the same time and achieve the purpose of picking up the food processor, making it more convenient for the user to pick up the food processor and further improving the user experience. At the same time, the air inlet includes a first air inlet and a second air inlet provided on the first gripping position and the second gripping position, which can simultaneously introduce air into the main body shell through the first air inlet and the second air inlet, thereby expanding the air intake area and thereby improving the air intake efficiency, thereby further improving the heat dissipation effect. The first air inlet and the second air inlet are respectively connected to the first cavity and the second cavity, so that the airflow entering the main body shell through the first air inlet and the second air inlet directly dissipates heat to the high temperature zone and the low temperature zone, and the two airflows dissipate heat to the high temperature zone and the low temperature zone independently, thereby avoiding the situation where turbulence caused by the meeting of the two airflows causes the airflow velocity to decrease and the heat dissipation effect to deteriorate, thereby ensuring the heat dissipation effect.

[0014] By providing the partition with a vent connecting the first cavity and the second cavity, the air inlet is located close to the first cavity, and the air outlet is close to the second cavity, so that the heat dissipation path of the airflow to the main unit is: air inlet-first cavity-ventilation-second cavity-air outlet, so that the low-temperature zone is located upstream of the high-temperature zone, so that the airflow first dissipates heat for the electrical components in the low-temperature zone and then dissipates heat for the IPM module, effectively avoiding the situation where the high-temperature zone is located upstream of the low-temperature zone, resulting in the airflow needing to pass through the IPM module before passing through the low-temperature zone, causing the airflow to rise in temperature after passing through the IPM module and having a small temperature difference with the electrical components in the low-temperature zone when passing through the low-temperature zone, thereby causing the heat dissipation effect of the electrical components in the low-temperature zone to deteriorate, further ensuring the heat dissipation effect of each component on the circuit board.

[0015] In a preferred implementation of a food processor with good heat dissipation effect, two gripping positions are provided and arranged laterally opposite to each other, each gripping position is provided with an air inlet, and the air outlet is arranged between the two air inlets.

[0016] By providing two grips, arranged horizontally opposite each other, it's easier for users to pick up the device. Each grip is also equipped with an air inlet, allowing air to enter the main housing simultaneously through both inlets, expanding the air intake area and improving air intake efficiency, further enhancing the heat dissipation effect. Furthermore, the air outlet is located between the two inlets, allowing airflow entering the main housing through the inlets to dissipate heat from the IPM modules in different areas on opposite sides before being discharged outward through the air outlet. This increases the area of airflow passing through the IPM module surface, further enhancing the heat dissipation effect.

[0017] In a preferred implementation of a food processor with good heat dissipation effect, the IPM module is further covered with heat dissipation fins, a plurality of heat dissipation fins are arranged side by side, and an air guide gap is formed between two adjacent heat dissipation fins, and the air guide gap is in the same direction as the gas flow in the main body housing; or,

[0018] The air guide gap is perpendicular to the gas flow direction in the main body shell.

[0019] By covering the IPM module with heat sink fins, with multiple fins arranged side by side and air gaps formed between adjacent fins, air passing near the IPM module can be quickly dissipated outward through the fins. Simultaneously, the airflow through the air gaps allows the heat from the fins to be quickly removed, further improving heat dissipation efficiency. Furthermore, the airflow through the air gaps is aligned with the airflow within the mainframe housing, allowing airflow to flow more quickly through the gaps, further enhancing heat dissipation.

[0020] By setting the air guide gap to be perpendicular to the gas flow direction in the host casing, the airflow entering the host casing needs to go through multiple tortuous bends in the air guide gap before it can flow to the air outlet, thereby increasing the residence time of the airflow in the host casing and further improving the heat dissipation effect.

[0021] In a preferred implementation of a food processor with good heat dissipation effect, the IPM module is further covered with heat dissipation fins, and the heat dissipation fins are arranged on a side close to the air inlet.

[0022] By placing the heat sink fins near the air inlet, the airflow entering the host through the air inlet can directly dissipate heat from the heat sink fins, and the airflow passing near the IPM module can quickly spread outward through the heat sink fins, further improving the heat dissipation efficiency.

[0023] In a preferred implementation of a food processor with good heat dissipation effect, the cup body assembly also includes a cup seat covered under the brushless motor, the cup seat is fixedly connected to the bottom of the cup body to form a first installation cavity, and a second installation cavity is formed in the main body shell, and the first installation cavity is connected to the heat dissipation cavity and the second installation cavity.

[0024] By connecting the first installation cavity with the second installation cavity, the airflow passes through the main unit and dissipates heat for the IPM module before entering the first installation cavity to dissipate heat for the brushless motor. This allows the airflow to dissipate heat for multiple components in the entire machine simultaneously, thereby improving the utilization rate of airflow heat dissipation and further improving the heat dissipation effect of the entire machine.

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

[0032] It should be noted that many specific details are 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.

[0033] like Figures 1 to 3 As shown, the utility model provides a food processing machine with good heat dissipation effect, including a main unit and a detachable cup body assembly arranged on the main unit, the cup body assembly includes a cup body 1 and a brushless motor 2 arranged below the cup body 1, the main unit includes a main unit housing 4 and an IPM module 51 arranged in the main unit housing 4 and cooperating with the brushless motor 2, the main unit housing 4 is provided with an inwardly recessed gripping position 41, the gripping position 41 is provided with an air inlet 411, and the IPM module 51 is arranged above the air inlet 411.

[0034] The present application uses a brushless motor 2 and, by virtue of the characteristics of the brushless motor 2, allows the user to use the food processor to process food ingredients with lower motor rotation noise, thereby achieving noise reduction. At the same time, the brushless motor 2 can achieve variable frequency control, allowing the food processor to control the brushless motor 2 to output different speeds according to different food ingredients and processing processes, thereby achieving better and more complete processing effects on food ingredients and improving the taste of the food ingredients. In addition, the brushless motor 2 occupies a smaller space, which helps to improve the compactness of the internal structure of the entire machine, reduce the space occupied by the food processor, and facilitate storage by users.

[0035] At the same time, the main body shell 4 is provided with an inwardly recessed gripping position 41, so that when the user is using the food processor, they can reach into the gripping position 41 to pick up the food processor, making it more convenient and quick for the user to pick up the food processor, thereby improving the user experience. In addition, an air inlet 411 is provided on the gripping position 41, so that outside air can enter the main body through the air inlet 411, thereby effectively dissipating heat from the various components within the main body. At the same time, the gripping position 41 can also allow air to enter while holding the main body, thus achieving functional integration and eliminating the need to set up air inlets 411 in other locations, thereby improving space utilization and ensuring the consistency of the main body appearance. In addition, the IPM module 51 is provided above the air inlet 411, so that the airflow entering the main body through the air inlet 411 can directly dissipate heat from the IPM module 51, effectively reducing the temperature rise of the IPM module 51 and avoiding the situation where the temperature rise of the IPM module 51 significantly leads to accelerated aging. This greatly improves the heat dissipation effect and reliability of the IPM module 51, thereby helping to increase the service life of the IPM module 51.

[0036] As a preferred embodiment of the present application, Figure 1 、 Figure 2 As shown, the host housing 4 is further provided with an air guide hood 6 covering the IPM module 51. The air guide hood 6 and the IPM module 51 cooperate to form a heat dissipation cavity. The host housing 4 is also provided with an air outlet 42. The heat dissipation cavity is connected to the air inlet 411 and the air outlet 42.

[0037] By also providing an air guide 6 in the main housing 4 that covers the IPM module 51, the air guide 6 and the IPM module 51 cooperate to form a heat dissipation cavity, so that the airflow entering the main housing 4 can enter the heat dissipation cavity through the guidance of the air guide 6, so that more airflow passes through the IPM module 51, thereby achieving effective heat dissipation of the main heat-generating component IPM module 51, further improving its heat dissipation effect, and avoiding the airflow entering the main housing 4 through the air inlet 411 from being dispersed, resulting in less airflow flowing through the IPM module 51 and causing its heat dissipation effect to be poor. At the same time, the main housing 4 is also provided with an air outlet 42, and the heat dissipation cavity connects the air inlet 411 and the air outlet 42, so that the air guide 6 connects the air inlet 411 and the air outlet 42, so that the heat dissipation airflow path in the main housing 4 is the air inlet 411-heat dissipation cavity-air outlet 42, thereby achieving maximum heat dissipation efficiency for the IPM module 51, which helps to further improve the heat dissipation effect.

[0038] As a preferred embodiment of this embodiment, Figure 1As shown, the food processor also includes a circuit board 5, an IPM module 51 is integrated on the circuit board 5, the circuit board 5 includes a low-temperature zone and a high-temperature zone with the IPM module 51, and the air guide cover 6 is provided with a partition 63 isolating between the low-temperature zone and the high-temperature zone to separate the heat dissipation cavity into a first cavity 61 with a low-temperature zone and a second cavity 62 with a high-temperature zone.

[0039] By providing a partition 63 between the low-temperature zone and the high-temperature zone on the air guide cover 6, the heat dissipation cavity is divided into a first cavity 61 with a low-temperature zone and a second cavity 62 with a high-temperature zone, so that the high-temperature zone and the low-temperature zone are isolated from each other by the partition 63, effectively avoiding the high-temperature heat in the high-temperature zone from being conducted to electrical components in the low-temperature zone, such as pre-charging resistors and relays, which can reduce the temperature rise of electrical components in the low-temperature zone and help improve the heat dissipation effect.

[0040] It should be noted that the present application does not specifically limit the structure of the lower air guide cover 6 of this embodiment, and it can be any one of the following embodiments:

[0041] Example 1: Figure 1 As shown, in this embodiment, the holding position 41 includes a first holding position 412 and a second holding position 413, and the air inlet 411 includes a first air inlet 4111 and a second air inlet 4112 provided on the first holding position 412 and the second holding position 413, and the first air inlet 4111 and the second air inlet 4112 are respectively connected to the first cavity 61 and the second cavity 62.

[0042] By setting the gripping position 41 to include a first gripping position 412 and a second gripping position 413, the user can use both hands to reach into the first gripping position 412 and the second gripping position 413 at the same time and take the food processor, making it more convenient for the user to take it and further improving the user experience. At the same time, the air inlet 411 includes a first air inlet 4111 and a second air inlet 4112 provided on the first gripping position 412 and the second gripping position 413, and can simultaneously introduce air into the main unit housing 4 through the first air inlet 4111 and the second air inlet 4112, thereby expanding the air inlet area and thereby improving the air inlet efficiency, thereby further improving the heat dissipation effect, and the first air inlet 4111 and the second air inlet 4112 are respectively connected to the first cavity 61 and the second cavity 62, so that the airflow entering the main unit housing 4 through the first air inlet 4111 and the second air inlet 4112 directly dissipates heat to the high temperature zone and the low temperature zone, and the two airflows independently dissipate heat to the high temperature zone and the low temperature zone, thereby avoiding the turbulence generated after the two airflows meet, causing the airflow velocity to decrease and thus resulting in a deterioration of the heat dissipation effect, thereby ensuring the heat dissipation effect.

[0043] Example 2: In this embodiment, the partition 63 is provided with a ventilation hole connecting the first cavity 61 and the second cavity 62. The air inlet 411 is located close to the first cavity 61, and the air outlet 42 is close to the second cavity 62, so that the air flow passes through the first cavity 61 and then passes through the second cavity 62 and is discharged from the air outlet 42.

[0044] By providing the partition 63 with a vent connecting the first cavity 61 and the second cavity 62, the air inlet 411 is located close to the first cavity 61, and the air outlet 42 is close to the second cavity 62, so that the heat dissipation path of the airflow to the host is: air inlet 411-first cavity 61-ventilation port-second cavity 62-air outlet 42, so that the low-temperature zone is located upstream of the high-temperature zone, so that the airflow first dissipates heat for the electrical components in the low-temperature zone and then dissipates heat for the IPM module 51, effectively avoiding the situation where the high-temperature zone is located upstream of the low-temperature zone, resulting in the airflow needing to pass through the IPM module 51 before passing through the low-temperature zone, causing the airflow to heat up after passing through the IPM module 51 and then passing through the low-temperature zone, resulting in a small temperature difference between the airflow and the electrical components in the low-temperature zone when passing through the low-temperature zone, thereby causing the heat dissipation effect of the electrical components in the low-temperature zone to deteriorate, further ensuring the heat dissipation effect of each component on the circuit board 5.

[0045] It should be noted that the present application does not specifically limit the relative relationship between the gripping position 41 and the air inlet 411. As a preferred embodiment of the present application, Figure 1 As shown, there are two gripping positions 41 that are arranged laterally opposite to each other, each gripping position 41 is provided with an air inlet 411 , and the air outlet 42 is arranged between the two air inlets 411 .

[0046] Providing two grips 41 and arranging them laterally opposite each other makes it easier for the user to pick up the device. Each grip 41 is also provided with an air inlet 411, allowing air to enter the main housing 4 simultaneously through both air inlets 411, thereby expanding the air intake area and improving air intake efficiency, thereby further enhancing the heat dissipation effect. Furthermore, the air outlet 42 is located between the two air inlets 411, allowing airflow entering the main housing 4 through the air inlets 411 to dissipate heat from the IPM modules 51 in different areas on opposite sides before being discharged outward through the air outlet 42. This increases the area of airflow passing through the surface of the IPM modules 51, further enhancing the heat dissipation effect.

[0047] Of course, in addition to the above settings, the holding position 41 can also be set to one, or three or more, and the air inlet 411 can be set on each holding position 41, or one or more air inlets 411 can be set. In addition, the air outlet 42 can be set to one or more, which will not be repeated here.

[0048] As a preferred embodiment of the present application, Figure 1As shown, the IPM module 51 is further covered with heat dissipation fins 52 . A plurality of heat dissipation fins 52 are arranged side by side, and an air guide gap is formed between two adjacent heat dissipation fins 52 .

[0049] By covering the IPM module 51 with heat dissipation fins 52, and arranging a plurality of heat dissipation fins 52 side by side, an air guide gap is formed between two adjacent heat dissipation fins 52, so that the air flow passing through the vicinity of the IPM module 51 can be quickly propagated outward through the heat dissipation fins 52. At the same time, the formation of the air guide gap allows the heat dissipation air to quickly take away the heat on the heat dissipation fins 52 through the air guide gap, thereby further improving the heat dissipation efficiency.

[0050] It should be noted that the present application does not specifically limit the air guide gap and the direction of the airflow, which can be any one of the following embodiments:

[0051] Embodiment 1: In this embodiment, the air guide gap is in the same direction as the gas flow in the main body housing 4.

[0052] By setting the air guide gap and the air flow direction in the main body shell 4 to be in the same direction, the air flow can pass through the air guide gap more quickly, thereby further improving the heat dissipation effect.

[0053] Example 2: Figure 1 As shown, in this embodiment, the air guide gap is perpendicular to the gas flow direction in the main body housing 4.

[0054] By setting the air guide gap to be perpendicular to the gas flow direction in the main housing 4, the airflow entering the main housing 4 needs to go through multiple tortuous bends in the air guide gap before it can flow to the air outlet 42, thereby increasing the residence time of the airflow in the main housing 4 and further improving the heat dissipation effect.

[0055] As a preferred embodiment of the present application, Figure 1 As shown, the IPM module 51 is also covered with heat dissipation fins 52 , which are arranged on a side close to the air inlet 411 .

[0056] By arranging the heat sink 52 near the air inlet 411, the airflow entering the host through the air inlet 411 can directly dissipate heat from the heat sink 52, and the airflow passing near the IPM module 51 can quickly propagate outward through the heat sink 52, further improving the heat dissipation efficiency.

[0057] It should be noted that the present application does not specifically limit the location and forming method of the air inlet 411, which can be any one of the following embodiments:

[0058] Example 1: Figure 1As shown, in this embodiment, the host housing 4 includes an outer shell and a base arranged below the outer shell, and the air inlet 411 is arranged on the base.

[0059] Embodiment 2: In this embodiment, the air inlet 411 is provided on the housing.

[0060] Embodiment 3: In this embodiment, the air inlet 411 includes a first opening provided on the housing and opening downward, and a second opening provided on the base and opening upward. The first opening and the second opening are connected to form the air inlet 411.

[0061] As a preferred embodiment of the present application, Figure 1 As shown, the cup body assembly also includes a cup holder 3 covered under the brushless motor 2. The cup holder 3 is fixedly connected to the bottom of the cup body 1 to form a first installation cavity 31. A second installation cavity is formed in the main body shell 4. The first installation cavity 31 is connected to the second installation cavity.

[0062] By connecting the first installation cavity 31 with the second installation cavity, the airflow passes through the main unit and dissipates heat for the IPM module 51 before entering the first installation cavity 31 to dissipate heat for the brushless motor 2, thereby enabling the airflow to dissipate heat for multiple components in the entire machine simultaneously, thereby improving the utilization rate of airflow heat dissipation and further improving the heat dissipation effect of the entire machine.

[0063] Furthermore, a first communication port is provided on the top wall of the main body housing 4 , a second communication port cooperating with the first communication port is provided on the bottom wall of the cup holder 3 , and an air outlet 42 is provided on the cup holder 3 .
