Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, and particularly relates to a food processor with good heat dissipation effect. Background Art

[0002] The existing food processor generally includes a main body and a cup assembly detachably arranged on the main body. The cup assembly includes a cup body, a brushless motor arranged below the cup body, and a cup base fixedly connected to the bottom of the cup body. When a user uses the food processor, food materials are put into the cup body, and the motor drives a crushing device to rotate at a high speed to realize the processing of the food materials. In order to improve the stability of the working process and reduce the generation of noise, a brushless motor is usually selected for the motor. During the high-speed rotation process, the brushless motor drives the air flow in the cup base, especially near the brushless motor, so as to realize the heat dissipation of the brushless motor. However, the heat generated by the brushless motor during the actual working process is less. In order to control components such as the motor, a circuit board for controlling the operation of components such as the motor is necessarily provided in the food processor. The working temperature of the electronic devices on the circuit board directly determines their service life and stability. During the working process, the circuit board will generate a certain amount of heat. At the same time, the circuit board is usually installed in the main body, and the air flow passing through the circuit board in the main body is less, resulting in a rapid rise in the temperature of the circuit board. The continuous temperature rise of the circuit board may cause the components on the circuit board to fail due to overheating, thereby affecting the performance of the food processor and reducing its working reliability. Content of the Utility Model

[0003] The purpose of the utility model is to provide a food processor with good heat dissipation effect, so as to solve the problem that the heat dissipation efficiency of the circuit board is low due to less air flow passing through the circuit board in the existing food processor, resulting in its easy overheating and failure.

[0004] To achieve the above purpose, the utility model provides a food processor with good heat dissipation effect, which includes a main body and a cup assembly detachably arranged on the main body. The cup assembly includes a cup body, a brushless motor arranged below the cup body, and a cup base fixedly connected to the bottom of the cup body. The cup base and the cup body enclose an installation cavity for accommodating the brushless motor. An IPM module cooperating with the brushless motor is also arranged in the installation cavity. A heat dissipation channel communicating with the outside is also formed in the installation cavity. Both the IPM module and the brushless motor are located in the heat dissipation channel.

[0005] The present application uses a brushless motor and takes advantage of the characteristics of the brushless motor to enable the user to use the food processor to process food with lower noise from the rotation of the motor, thereby achieving a noise reduction effect. 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 a small 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 user storage.

[0006] At the same time, the cup seat and the cup body are enclosed to form an installation cavity for accommodating the brushless motor. The installation cavity is also provided with an IPM module that cooperates with the brushless motor, so that the installation cavity can not only realize the installation of the brushless motor, but also realize the installation of the IPM module, which helps to improve the compactness of the components in the installation cavity, and then improve the compactness of the entire cup body assembly. Compared with the existing method of installing the IPM module in the host, the number of components in the host can be reduced, which helps to reduce the vertical size of the host, and then the center of gravity of the entire machine is lower after the cup body assembly is placed on the host, which helps to improve the stability of the machine when working. In addition, a heat dissipation channel connected to the outside is formed in the installation cavity. The IPM module and the brushless motor are both located in the heat dissipation channel, so that the cold air entering the installation cavity can not only realize the heat dissipation of the brushless motor, but also realize the heat dissipation of the IPM module, which can effectively reduce the temperature rise of the brushless motor and the IPM module, and avoid the situation where the temperature rise of the brushless motor and the IPM module is obvious, which leads to accelerated aging, greatly improves the heat dissipation effect and reliability of the IPM module and the brushless motor, and realizes rapid heat dissipation and life extension of the whole machine.

[0007] In a preferred implementation of a food processor with good heat dissipation effect, the IPM module is arranged upstream of the brushless motor in the gas flow path in the heat dissipation channel, so that the air flow in the heat dissipation channel passes through the IPM module first and then passes through the brushless motor.

[0008] By arranging the IPM module upstream of the gas flow path in the heat dissipation channel relative to the brushless motor, the air flow entering the heat dissipation channel can first pass through the IPM module and then through the brushless motor. That is, the air flow can first cool the IPM module and then dissipate heat from the brushless motor. Thus, the air flow with a lower temperature cools the IPM module, increasing the temperature difference between the air flow and the IPM module, thereby enhancing the heat dissipation effect on the IPM module, further reducing the temperature rise of the IPM module. At the same time, the air flow after cooling the IPM module will pass through the brushless motor again to dissipate heat from the brushless motor, avoiding the situation where the brushless motor is located upstream of the IPM module, resulting in the air flow entering the heat dissipation channel passing through the brushless motor first and then through the IPM module, and the temperature-rise air flow after passing through the brushless motor having a smaller temperature difference with the IPM module when passing through the IPM module, causing a poor heat dissipation effect on the IPM module, and ensuring the heat dissipation effects of both the brushless motor and the IPM module.

[0009] In a preferred implementation manner of a food processor with good heat dissipation effect, the cup holder is provided with a cup holder air inlet, and the IPM module is arranged on one side close to the cup holder air inlet.

[0010] By arranging the cup holder with a cup holder air inlet and the IPM module on one side close to the cup holder air inlet, after the outside air enters the heat dissipation channel through the cup holder air inlet, it can directly and effectively dissipate heat from the IPM module, reducing the loss of the air flow entering the heat dissipation channel, enabling more air flow to pass through the IPM module, and helping to further enhance the heat dissipation effect on the IPM module.

[0011] In a preferred implementation manner of a food processor with good heat dissipation effect, an air inlet duct is provided in the main body, and the air inlet duct is communicated with the heat dissipation channel so that the gas enters the heat dissipation channel through the air inlet duct.

[0012] By arranging the air inlet duct in the main body and the air inlet duct being communicated with the heat dissipation channel, the air flow passes through the main body and then enters the heat dissipation channel to dissipate heat from the IPM module and the brushless motor, enabling the air flow to dissipate heat from other components in the main body and then dissipate heat from the IPM module and the brushless motor, allowing the air flow to dissipate heat from multiple components in the whole machine synchronously, improving the utilization rate of the air flow for heat dissipation, and being able to further enhance the heat dissipation effect of the whole machine.

[0013] In a preferred implementation manner of a food processor with good heat dissipation effect, the main body includes a main body housing. The air inlet duct includes a main body air inlet provided on the bottom wall of the main body housing and a main body air outlet provided on the top wall of the main body housing. The heat dissipation channel includes a cup holder air inlet provided on the bottom wall of the cup holder, and the cup holder air inlet is communicated with the main body air outlet.

[0014] By setting the air inlet duct to include the main machine air inlet provided on the bottom wall of the main machine housing, the main machine air inlet is arranged close to the desktop side, realizing the concealment of the main machine air inlet, which helps to ensure the consistency of the overall appearance of the machine and at the same time can reduce the inhalation of external dust.

[0015] In a preferred implementation of a food processor with good heat dissipation effect, a wind guide cylinder connecting the main machine air inlet and the main machine air outlet is provided between the main machine air inlet and the main machine air outlet.

[0016] By providing a wind guide cylinder connecting the main machine air inlet and the main machine air outlet between the main machine air inlet and the main machine air outlet, the air flow entering the main machine through the main machine air inlet can flow directly into the heat dissipation channel through the guidance of the wind guide cylinder through the main machine air outlet, which helps to improve the efficiency of the air flow flowing into the heat dissipation channel, and then improve the rate of gas flow in the heat dissipation channel, and further improve the heat dissipation efficiency of the brushless motor and the IPM module, avoiding the situation that the air flow entering the main machine is relatively scattered, resulting in less air flow entering the heat dissipation channel and lower heat dissipation efficiency of the brushless motor and the IPM module.

[0017] In a preferred implementation of a food processor with good heat dissipation effect, the heat dissipation channel further includes a cup holder air outlet provided on the side wall or the top wall of the cup holder, so that the gas can be discharged outward through the cup holder air outlet after passing through the heat dissipation channel; or,

[0018] The heat dissipation channel further includes a cup holder air outlet provided on the bottom wall of the cup holder. An air outlet channel is also provided in the main machine, and the air outlet channel is communicated with the cup holder air outlet, so that the gas can be discharged outward through the air outlet channel after passing through the cup holder air outlet.

[0019] By setting the cup holder air outlet on the side wall or the top wall of the cup holder, the air flow can be directly discharged outward through the cup holder air outlet after dissipating heat from the brushless motor and the IPM module, which can improve the efficiency of the air flow discharging outward, and then improve the rate of air flow flowing in the heat dissipation channel, so as to further improve the air flow rate passing through the brushless motor and the IPM module per unit time, so as to further improve the heat dissipation effect on them.

[0020] By providing an air outlet channel in the main machine and the air outlet channel is communicated with the cup holder air outlet, the air flow needs to be discharged to the outside through the air outlet duct after dissipating heat from the brushless motor and the IPM module, so that the air flow can pass through the main machine for the second time to realize the secondary cooling of the internal components of the main machine, which helps to improve the heat dissipation effect on the internal components of the main machine and further improve the heat dissipation of the whole machine.

[0021] In a preferred implementation of a food processor with good heat dissipation effect, the heat dissipation channel includes a cup holder air inlet and a cup holder air outlet provided on the cup holder, so that the gas can enter the installation cavity through the cup holder air inlet and then be discharged outward through the cup holder air outlet.

[0022] By setting the heat dissipation channel to include an air inlet of the cup holder and an air outlet of the cup holder, the air flow can enter the installation cavity after passing through the air inlet of the cup holder, so as to realize the heat dissipation of the brushless motor and the IPM module. The heat-dissipated air flow can be directly discharged outwards through the air outlet of the cup holder, which further increases the flow rate of the air flow, eliminating the need to pass through the main body and then through the cup holder to realize the heat dissipation of the brushless motor and the IPM module, and contributing to further improving the heat dissipation effect.

[0023] In a preferred implementation of a food processor with good heat dissipation effect, the cup body assembly further includes a heating plate fixed below the cup body, and the heating plate is located in the heat dissipation channel.

[0024] By arranging the heating plate in the heat dissipation channel, the air flow can not only dissipate heat from the brushless motor and the IPM module, but also dissipate heat from the heating plate, which helps to reduce the heat conduction from the heating plate to the brushless motor, thereby avoiding the situation that the brushless motor has a significant temperature rise and serious aging, and contributing to extending its service life and ensuring the stability of operation.

[0025] In a preferred implementation of a food processor with good heat dissipation effect, the heating plate is located at the end of the gas flow path in the heat dissipation channel.

[0026] By arranging the heating plate at the end of the gas flow path in the heat dissipation channel, the air flow entering the heat dissipation channel first dissipates heat from the brushless motor and the IPM module and then dissipates heat from the heating plate, so that the air flow first dissipates heat from the components with lower temperature and then passes through the heating plate with higher temperature to dissipate heat, avoiding the situation that the air flow first passes through the heating plate, resulting in a significant temperature rise of the air flow and poor heat dissipation effect or even inability to dissipate heat for the brushless motor and the IPM module.

Detailed implementation mode

[0033] To more clearly illustrate the overall concept of the present invention, the following will be described in detail by way of examples in combination with the accompanying drawings of the specification.

[0034] 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 protection scope of the present invention is not limited by the specific implementation modes disclosed below.

[0035] As Figures 1 to 2 As shown, the present invention provides a food processor with good heat dissipation effect, including a main body 2 and a cup body assembly detachably arranged on the main body 2. The cup body assembly includes a cup body 1, a brushless motor 3 arranged below the cup body 1, and a cup holder 4 fixedly connected to the bottom of the cup body 1. The cup holder 4 and the cup body 1 enclose an installation cavity 41 for accommodating the brushless motor 3. An IPM module 5 cooperating with the brushless motor 3 is also arranged in the installation cavity 41. A heat dissipation channel communicating with the outside is also formed in the installation cavity 41. Both the IPM module 5 and the brushless motor 3 are located in the heat dissipation channel.

[0036] In this application, by using the brushless motor 3 and relying on the characteristics of the brushless motor 3, when the user uses the food processor to process food materials, the noise generated by the rotation of the motor is lower, achieving the effect of noise reduction. At the same time, the brushless motor 3 can achieve variable frequency control, enabling the food processor to control the brushless motor 3 to output different speeds according to different food materials and during the processing process, which can make the processing effect of the food materials better and the processing more sufficient, improving the output taste of the food materials. Moreover, the brushless motor 3 occupies less space, which helps to improve the compactness of the internal structure of the whole machine, reduce the occupied space of the food processor, and facilitate the user to store it.

[0037] Meanwhile, the cup holder 4 and the cup body 1 enclose to form an installation cavity 41 for accommodating the brushless motor 3. An IPM module 5 that cooperates with the brushless motor 3 is also provided in the installation cavity 41. This enables not only the installation of the brushless motor 3 in the installation cavity 41 but also the installation of the IPM module 5, which helps improve the compactness of the components in the installation cavity 41, thereby enhancing the compactness of the entire cup body assembly. Moreover, compared with the existing method of installing the IPM module 5 in the main body 2, it can reduce the number of internal components in the main body 2, which helps to reduce the vertical size of the main body 2. As a result, when the cup body assembly is placed on the main body 2, the center of gravity of the entire machine is lower, which helps improve the stability of the machine during operation. Additionally, a heat dissipation channel communicating with the outside is formed in the installation cavity 41. Both the IPM module 5 and the brushless motor 3 are located in the heat dissipation channel, allowing the cold air entering the installation cavity 41 to not only dissipate heat from the brushless motor 3 but also dissipate heat from the IPM module 5. This can effectively reduce the temperature rise of the brushless motor 3 and the IPM module 5, avoiding the situation where the obvious temperature rise of the brushless motor 3 and the IPM module 5 accelerates their aging, greatly improving the heat dissipation effect and reliability of the IPM module 5 and the brushless motor 3, and achieving rapid heat dissipation and lifespan improvement of the entire machine.

[0038] It should be noted that the relative positions of the brushless motor 3 and the IPM module 5 in this application are not specifically limited. As a preferred embodiment of this application, as Figure 2 shown, the IPM module 5 is arranged upstream of the brushless motor 3 in the gas flow path in the heat dissipation channel, so that the air flow in the heat dissipation channel first passes through the IPM module 5 and then passes through the brushless motor 3.

[0039] By arranging the IPM module 5 upstream of the brushless motor 3 in the gas flow path in the heat dissipation channel, the air flow entering the heat dissipation channel can first pass through the IPM module 5 and then pass through the brushless motor 3. That is, the air flow can first cool the IPM module 5 and then dissipate heat from the brushless motor 3. Thus, the air flow with a lower temperature dissipates heat from the IPM module 5, increasing the temperature difference between the air flow and the IPM module 5, thereby enhancing the heat dissipation effect on the IPM module 5 and further reducing the temperature rise of the IPM module 5. At the same time, the air flow after cooling the IPM module 5 will pass through the brushless motor 3 again to dissipate heat from the brushless motor 3, avoiding the situation where the brushless motor 3 is located upstream of the IPM module 5, resulting in the air flow entering the heat dissipation channel having to pass through the brushless motor 3 first and then the IPM module 5, and the air flow with a temperature rise after passing through the brushless motor 3 having a smaller temperature difference with the IPM module 5 when passing through the IPM module 5, which deteriorates the heat dissipation effect on the IPM module 5, and ensuring the heat dissipation effect of the brushless motor 3 and the IPM module 5.

[0040] Furthermore, as Figure 2As shown in the figure, the cup holder 4 is provided with a cup holder air inlet 42, and the IPM module 5 is arranged on one side close to the cup holder air inlet 42.

[0041] By providing the cup holder 4 with a cup holder air inlet 42 and arranging the IPM module 5 on one side close to the cup holder air inlet 42, after the outside air enters the heat dissipation channel through the cup holder air inlet 42, it can directly dissipate heat from the IPM module 5 effectively, reduce the loss of the air flow entering the heat dissipation channel, and enable more air flow to pass through the IPM module 5, which helps to further improve the heat dissipation effect on the IPM module 5.

[0042] It should be noted that the present application does not specifically limit the setting of the heat dissipation channel, and it can be any one of the following embodiments:

[0043] Embodiment 1: As Figure 2 shown, in this embodiment, an air inlet duct is provided in the host 2, and the air inlet duct is communicated with the heat dissipation channel so that the gas enters the heat dissipation channel through the air inlet duct.

[0044] By providing an air inlet duct in the host 2 and communicating the air inlet duct with the heat dissipation channel, the air flow enters the heat dissipation channel after passing through the host 2 to dissipate heat from the IPM module 5 and the brushless motor 3, so that the air flow can dissipate heat from other components in the host 2 and then dissipate heat from the IPM module 5 and the brushless motor 3, enabling the air flow to dissipate heat from multiple components in the whole machine synchronously, improving the utilization rate of the air flow for heat dissipation, and further improving the heat dissipation effect of the whole machine.

[0045] Furthermore, as Figure 2 shown, the host 2 includes a host housing 21. The air inlet duct includes a host air inlet 211 provided on the bottom wall of the host housing 21 and a host air outlet 212 provided on the top wall of the host housing 21. The heat dissipation channel includes a cup holder air inlet 42 provided on the bottom wall of the cup holder 4, and the cup holder air inlet 42 is communicated with the host air outlet 212.

[0046] By setting the air inlet duct to include the host air inlet 211 provided on the bottom wall of the host housing 21, the host air inlet 211 is arranged close to the desktop side, realizing the hiding of the host air inlet 211, which helps to ensure the consistency of the appearance of the whole machine and can also reduce the inhalation of external dust.

[0047] Furthermore, it should be noted that the present application does not specifically limit the air flow path in this embodiment, and it can be any one of the following implementation manners:

[0048] Implementation manner 1: As Figure 2 shown, in this implementation manner, the heat dissipation channel further includes a cup holder air outlet 43 provided on the side wall or the top wall of the cup holder 4, so that the gas is discharged outward through the cup holder air outlet 43 after passing through the heat dissipation channel.

[0049] By arranging the cup holder air outlet 43 on the side wall or the top wall of the cup holder 4, after the airflow cools the brushless motor 3 and the IPM module 5, it can directly discharge outward through the cup holder air outlet 43, which can improve the efficiency of the airflow discharging outward, thereby increasing the flow rate of the airflow flowing in the heat dissipation channel, and further increasing the airflow volume passing through the brushless motor 3 and the IPM module 5 per unit time, so as to further improve the heat dissipation effect on them.

[0050] Embodiment 2: In this embodiment, the heat dissipation channel further includes a cup holder air outlet 43 provided on the bottom wall of the cup holder 4. An air outlet channel is also provided in the main body 2, and the air outlet channel is communicated with the cup holder air outlet 43, so that the gas is discharged outward through the air outlet channel after passing through the cup holder air outlet 43.

[0051] By providing an air outlet channel in the main body 2 and the air outlet channel being communicated with the cup holder air outlet 43, the airflow needs to be discharged outward to the outside through the air outlet duct after cooling the brushless motor 3 and the IPM module 5, so that the airflow can pass through the main body 2 twice to realize the secondary cooling of the internal components of the main body 2, which helps to improve the heat dissipation effect on the internal components of the main body 2 and further improve the heat dissipation of the whole machine.

[0052] As a preference in this embodiment, as Figure 2 shown, a wind guide cylinder 6 for connecting the two is provided between the main body air inlet 211 and the main body air outlet 212.

[0053] By providing a wind guide cylinder 6 for connecting the main body air inlet 211 and the main body air outlet 212, the airflow entering the main body 2 through the main body air inlet 211 can directly flow into the heat dissipation channel through the guidance of the wind guide cylinder 6 through the main body air outlet 212, which helps to improve the efficiency of the airflow flowing into the heat dissipation channel, thereby increasing the flow rate of the gas flowing in the heat dissipation channel, and further improving the heat dissipation efficiency of the brushless motor 3 and the IPM module 5, avoiding the situation that the airflow entering the main body 2 is relatively dispersed, resulting in less airflow entering the heat dissipation channel and lower heat dissipation efficiency of the brushless motor 3 and the IPM module 5.

[0054] Embodiment 2: As Figure 3 shown, in this embodiment, the heat dissipation channel includes a cup holder air inlet 42 and a cup holder air outlet 43 provided on the cup holder 4, so that the gas enters the installation cavity 41 through the cup holder air inlet 42 and then is discharged outward through the cup holder air outlet 43.

[0055] By setting the heat dissipation channel to include an air inlet 42 and an air outlet 43 of the cup holder 4, the air flow enters the installation cavity 41 after passing through the air inlet 42 of the cup holder, so as to dissipate the heat of the brushless motor 3 and the IPM module 5. The heat-dissipated air flow can be directly discharged out through the air outlet 43 of the cup holder, which further increases the flow rate of the air flow, eliminating the need to pass through the main body 2 and then through the cup holder 4 to dissipate the heat of the brushless motor 3 and the IPM module 5, and contributing to further improving the heat dissipation effect.

[0056] As a preferred embodiment of the present application, as Figure 2 shown, the cup assembly further includes a heating plate 7 fixed below the cup body 1, and the heating plate 7 is located in the heat dissipation channel.

[0057] By arranging the heating plate 7 in the heat dissipation channel, the air flow can not only dissipate the heat of the brushless motor 3 and the IPM module 5, but also dissipate the heat of the heating plate 7, which helps to reduce the heat conduction from the heating plate 7 to the brushless motor 3, thereby avoiding the situation that the temperature rise of the brushless motor 3 is obvious and its aging is serious, and contributing to extending its service life and ensuring the working stability.

[0058] Furthermore, as Figure 2 shown, the heating plate 7 is located at the end of the gas flow path in the heat dissipation channel.

[0059] By arranging the heating plate 7 at the end of the gas flow path in the heat dissipation channel, the air flow entering the heat dissipation channel first dissipates the heat of the brushless motor 3 and the IPM module 5 and then dissipates the heat of the heating plate 7, so that the air flow first dissipates the heat of the components with lower temperature and then passes through the heating plate 7 with higher temperature for heat dissipation, avoiding the situation that the air flow first passes through the heating plate 7, resulting in obvious temperature rise of the air flow and poor heat dissipation effect or even inability to dissipate heat of the brushless motor 3 and the IPM module 5.

[0060] The technical solution protected by the present utility model is not limited to the above embodiments. It should be noted that the combination of the technical solution of any one embodiment with the technical solutions of one or more other embodiments is within the protection scope of the present utility model. Although the present utility model has been described in detail with general descriptions and specific embodiments above, on the basis of the present utility model, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present utility model all belong to the scope required to be protected by the present utility model.
