Description

TECHNICAL FIELD

[0001] The utility model relates to life electric appliance technical field, concretely relates to a food processor with good heat dissipation effect. BACKGROUND

[0002] With the development of society, the improvement of living standards, people's pursuit of food diversification and food health is constantly improved. So various industrial food processors gradually miniaturized into thousands of households, such as soybean milk machine, not only meet people's demand for food health, nutrition, but also greatly improve people's life quality, so it is loved by people.

[0003] The existing food processor usually includes a main machine and a cup body assembly detachably arranged on the main machine, the cup body assembly includes a cup body provided with a crushing cavity and a motor arranged at the bottom of the cup body and in transmission connection with a crushing device in the crushing cavity, and the user puts the food into the cup body when using the food processor, and the motor drives the crushing device to rotate at high speed to realize the processing of the food. But the motor will generate high heat during high-speed rotation, in order to realize the cooling of the motor, such as Chinese utility model patent CN201920286880.1 discloses a wall breaking food processor provided with an air inlet pipe, which makes the airflow enter the main machine and then enter the cup body assembly to realize the heat dissipation of the motor, and the airflow after heat dissipation is discharged outward through the main machine, so as to realize the heat dissipation of the motor and reduce the temperature rise of the motor.

[0004] With the innovation of food processor technology, in order to improve the stability of the working process and reduce the noise, some manufacturers upgrade the motor to a brushless motor, and in order to realize the control of the brushless motor and other components, the power board for controlling the work of the brushless motor and other components is indispensable in the food processor. The brushless motor usually includes a shell formed with a mounting cavity and a motor body arranged in the mounting cavity. The heat generated by the motor body during high-speed rotation cannot be well transmitted outward in the mounting cavity, so it will cause the temperature rise of the whole brushless motor, and the power board is directly exposed in the main machine, which can make the generated heat directly transmitted to the outside, so as to achieve better heat dissipation effect. Therefore, the temperature rise of the brushless motor is relatively higher than that of the power board, and the continuous temperature rise may cause the brushless motor to be seriously aged due to overheating, thereby affecting the performance of the food processor and reducing the working reliability. UTILITY MODEL CONTENTS

[0005] The utility model aims at providing a food processor with good heat dissipation effect, which solves the problem that the heat generated by the brushless motor in the existing food processor cannot be discharged in time and the poor heat dissipation effect leads to easy overheating and serious aging of the brushless motor.

[0006] In order to achieve the above object, the utility model provides a food processor with good heat dissipation effect, including host computer and the cup body component of detachable cup body component is established in host computer, cup body component includes cup body, brushless motor of cup body below and cup seat of cup body bottom fixed link, cup seat and cup body enclose and form the installation cavity containing brushless motor, host computer shell is formed with containing cavity containing IPM module in, host computer shell is equipped with the heat dissipation channel of mutual communication of installation cavity, and heat dissipation channel and containing cavity are mutually isolated.

[0007] The present application sets up a brushless motor in the food processor, and the noise of the motor rotation is lower when the user uses the food processor to process food materials, realizing the effect of noise reduction. At the same time, the brushless motor can realize frequency conversion control, so that the food processor can control the brushless motor to output different speeds according to different food materials and processing processes, which can make the processing effect of food materials better and more sufficient, improve the taste of the processed food, and the brushless motor occupies less space, which helps to improve the compactness of the internal structure of the whole machine, greatly reducing the size of the brushless motor and the cup body in the axial direction.

[0008] At the same time, by setting the brushless motor in the installation cavity and the IPM module in the containing cavity, the brushless motor and the IPM module are isolated, so that when the food processor is used, the heat dissipated by the brushless motor and the heat dissipated by the IPM can be effectively avoided, which can prevent the temperature rise of the whole machine from causing the brushless motor and the IPM module to age seriously. And the host computer shell is provided with a heat dissipation channel in communication with the installation cavity, so that when the user uses the food processor, the external gas can enter the installation cavity through the heat dissipation channel, and the optimal heat dissipation of the components in the installation cavity, such as the brushless motor, can be realized, the temperature rise of the brushless motor is reduced, the working stability is ensured, and the situation that the temperature rise of the brushless motor causes the brushless motor to age quickly is avoided. At the same time, the heat dissipation channel and the containing cavity are mutually isolated, so that the airflow in the heat dissipation channel only realizes heat dissipation for the brushless motor. Compared with the existing scheme that the airflow first passes through the IPM module and then passes through the brushless motor, the situation that the airflow first heats the IPM module and then heats the brushless motor after passing through the IPM module is effectively avoided, which causes the temperature difference between the airflow after passing through the IPM module and the brushless motor to be small, resulting in poor heat dissipation effect of the brushless motor. The heat dissipation effect of the brushless motor is ensured. At the same time, the IPM module in the containing cavity can realize self-heat dissipation by relying on its own heat dissipation fins and other heat dissipation components, thereby ensuring the heat dissipation effect of the brushless motor and the IPM module. And the heat dissipation channel only passes through the brushless motor to realize the simplification of the heat dissipation channel, which helps to realize the simplification of the structure of the whole machine, reduce the occupied space of the whole machine, and facilitate the user to store it.

[0010] By setting the heat dissipation channel to include the air inlet duct and the air outlet duct formed in the main machine shell, and the air inlet duct and the air outlet duct both being communicated with the mounting cavity, when the food processor is working, the airflow first enters the mounting cavity through the air inlet duct, and after realizing heat dissipation of the brushless motor in the mounting cavity, the airflow is discharged to the outside through the air outlet duct, thereby realizing effective heat dissipation of the brushless motor.

[0011] In a preferred implementation of the food processor with good heat dissipation effect, the main machine shell further has a first air guide cover, and the air inlet duct and the air outlet duct are formed in the first air guide cover.

[0016] By setting the first air guide cover to include a first cover body forming the air inlet duct and a second cover body forming the air outlet duct, the air inlet duct and the air outlet duct are isolated, thereby avoiding interference between the air flow in the air inlet duct and the air outlet duct, resulting in low air flow efficiency and poor heat dissipation effect of the brushless motor. At the same time, the first cover body and the second cover body are arranged side by side along the extension direction of the main machine, improving the rationality of the layout of the first air guide cover in the main machine, and further improving the compactness of the structure in the main machine.

At the same time, the first main machine air outlet and the first main machine air inlet are arranged in the mounting groove, realizing the hiding of the two, thereby avoiding the exposure of the two to the outside, causing the outside dirt to easily enter the main machine through the first main machine air outlet and the first main machine air inlet, and ensuring the cleanliness of the main machine.

Specific implementation

[0036] In order to more clearly explain the overall concept of the utility model, the following in conjunction with the drawings in the specification is described in detail by way of example.

[0037] It should be noted that in the following description, a lot of specific details are set forth in order to provide a thorough understanding of the utility model, however, the utility model can also be implemented in other ways different from the description herein, therefore, the protection scope of the utility model is not limited by the specific embodiments disclosed below.

[0038] As Figures 1 to 8 Indicated, the utility model provides a food processor with good heat dissipation effect, including host 4 and detachable cup body assembly on host 4, cup body assembly includes cup body 1, the brushless motor 2 below cup body 1 is established and is connected with cup body 1 bottom cup seat 3 of fixedly, cup seat 3 and cup body 1 enclose and form the mounting cavity 31 containing brushless motor 2, host 4 includes host shell 41, and the containing cavity 61 containing IPM module 5 is formed in host shell 41, and host shell 41 is equipped with the heat dissipation channel of intercommunication with mounting cavity 31, and heat dissipation channel and containing cavity 61 are mutually isolated.

[0039] This application incorporates a brushless motor 2 within a food processor. Utilizing the characteristics of the brushless motor 2, the noise level during food processing is reduced, achieving noise reduction. Furthermore, the brushless motor 2 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 2 occupies less space, contributing to a more compact internal structure and significantly reducing the axial dimensions of the brushless motor 2 relative to the cup body 1.

[0040] Meanwhile, by placing the brushless motor 2 inside the mounting cavity 31 and the IPM module 5 inside the receiving cavity 61, isolation is achieved between the brushless motor 2 and the IPM module 5. This effectively prevents the heat dissipated by the brushless motor 2 from merging with the heat dissipated by the IPM during the use of the food processor, thus avoiding significant temperature rise and severe aging of components such as the brushless motor 2 and the IPM module 5. Furthermore, the main housing 41 has a heat dissipation channel that communicates with the mounting cavity 31, allowing external air to enter the mounting cavity 31 through the heat dissipation channel during the use of the food processor. This achieves optimal heat dissipation for components such as the brushless motor 2 inside the mounting cavity 31, reducing the temperature rise of the brushless motor 2, ensuring its operational stability, and preventing significant temperature rise that could accelerate its aging. Meanwhile, the heat dissipation channel is isolated from the receiving cavity 61, ensuring that the airflow within the channel only dissipates heat from the brushless motor 2. Compared to existing solutions where the airflow first passes through the IPM module 5 and then the brushless motor 2, this effectively avoids the situation where the airflow, after cooling the IPM module 5, becomes hotter and, due to the smaller temperature difference between the airflow and the brushless motor 2, reduces the heat dissipation effect, thus guaranteeing the effective cooling of the brushless motor 2. Furthermore, the IPM module 5, within the receiving cavity 61, can achieve independent heat dissipation using its own heat dissipation fins and other heat dissipation components, further ensuring the cooling effect of both the brushless motor 2 and the IPM module 5. Moreover, the simplification of the heat dissipation channel, with only the brushless motor 2 passing through, contributes to a simpler overall structure, reduces the space occupied by the device, and facilitates user storage.

[0041] As a preferred embodiment of this application, such as Figure 1 As shown, the heat dissipation channel includes an air inlet duct and an air outlet duct formed in the main unit housing 41, and both the air inlet duct and the air outlet duct are connected to the mounting cavity 31.

[0042] By setting the heat dissipation channel to include the air inlet duct and the air outlet duct which are formed in the main machine shell 41 and which are both in communication with the mounting cavity 31, when the food processor is in operation, the airflow first enters the mounting cavity 31 through the air inlet duct, and after heat dissipation of the brushless motor 2 is achieved in the mounting cavity 31, the airflow is discharged to the outside through the air outlet duct, thereby achieving effective heat dissipation of the brushless motor 2.

[0043] It should be noted that the application does not make specific limitations on the formation of the air inlet duct and the air outlet duct, which can be directly formed in the main machine shell 41, or can be formed by two air deflectors. As a preferred embodiment of the application, as shown in Figure 1 、 Figure 5 、 Figure 6 、 Figure 7 , the main machine shell 41 is further provided with a first air deflector 6, and the air inlet duct and the air outlet duct are formed in the first air deflector 6.

[0044] By further providing the first air deflector 6 in the main machine shell 41, and forming the air inlet duct and the air outlet duct in the first air deflector 6, on the one hand, the formation of the air inlet duct and the air outlet duct is achieved by the first air deflector 6, which guides the airflow, allowing more airflow to enter the air inlet duct and the air outlet duct, which helps to improve the airflow through the brushless motor 2, thereby improving the heat dissipation effect of the brushless motor 2, and avoiding the situation that the airflow cannot be concentrated and dispersed after entering the main machine shell 41, causing the airflow to enter the mounting cavity 31 in time, resulting in poor heat dissipation of the brushless motor 2. On the other hand, the air inlet duct and the air outlet duct are both formed in the first air deflector 6, achieving one for two, which helps to further simplify the structure in the main machine 4, thereby further improving the compactness of the main machine 4.

[0045] It should be further noted that the application does not make specific limitations on the formation of the accommodating cavity 61 in this embodiment, which can be provided with a bracket in the main machine shell 41, and the accommodating cavity 61 is formed in the bracket. As a preferred embodiment of the application, as shown in Figure 8 , the IPM module 5 is arranged between the bottom wall of the main machine shell 41 and the first air deflector 6, the first air deflector 6 is provided with a downwardly open accommodating groove 64, and the accommodating groove 64 and the bottom wall of the shell form the accommodating cavity 61.

[0046] By providing the first air deflector 6 with the downwardly open accommodating groove 64, the accommodating groove 64 and the bottom wall of the shell form the accommodating cavity 61, that is, the first air deflector 6 can form the accommodating cavity 61 with the bottom wall of the shell while forming the air inlet duct and the air outlet duct, achieving one for three of the first air deflector 6, eliminating the need for another component to form the accommodating cavity 61, which helps to further simplify the structure in the main machine 4, thereby further improving the compactness of the main machine 4.

[0047] As a preferred under this embodiment, as shown in Figure 8 The first air guide 6 includes a first cover body 62 forming the air inlet channel and a second cover body 63 forming the air outlet channel, and the first cover body 62 and the second cover body 63 extend along the extension direction of the main machine 4 and are arranged side by side.

[0048] By setting the first air guide 6 to include a first cover body 62 forming the air inlet channel and a second cover body 63 forming the air outlet channel, the air inlet channel and the air outlet channel are isolated, thereby avoiding interference between the air flow in the air inlet channel and the air outlet channel, resulting in low air flow efficiency and poor heat dissipation effect of the brushless motor 2. At the same time, the first cover body 62 and the second cover body 63 are arranged side by side along the extension direction of the main machine 4, which improves the rationality of the layout of the first air guide 6 in the main machine 4, and further improves the compactness of the structure in the main machine 4.

[0049] As a preferred embodiment of the present application, as shown in Figure 4 The top of the main machine shell 41 is concave to form a mounting groove 411 accommodating the cup seat 3, and the bottom wall of the mounting groove 411 is provided with a first main machine air inlet 412 communicating the air inlet channel and the mounting cavity 31 and a first main machine air outlet 413 communicating the air outlet channel and the mounting cavity 31.

[0050] By concavely forming the mounting groove 411 on the top of the main machine shell 41 to accommodate the cup seat 3, the cup body 1 can be effectively limited after being mounted on the main machine 4, improving the stability of the connection and cooperation between the cup body 1 and the main machine 4, thereby avoiding the situation that the cup body 1 swings greatly during food processing, producing noise or even interrupting food processing. At the same time, the bottom wall of the mounting groove 411 is provided with a first main machine air inlet 412 communicating the air inlet channel and the mounting cavity 31 and a first main machine air outlet 413 communicating the air outlet channel and the mounting cavity 31, so that the air entering the main machine 4 can pass through the air inlet channel, then enter the mounting cavity 31 through the first main machine air inlet 412 to dissipate heat for the brushless motor 2 and other components, and then enter the air outlet channel through the first main machine air outlet 413 and be discharged to the outside, realizing the whole heat dissipation process. The first main machine air outlet 413 and the first main machine air inlet 412 are both arranged in the mounting groove 411, realizing the hiding of the two, thereby avoiding the situation that the two are exposed to the outside, causing the outside dirt to easily enter the main machine 4 through the first main machine air outlet 413 and the first main machine air inlet 412, ensuring the cleanliness of the main machine 4.

[0051] Further, as shown in Figure 4 The mounting groove 411 is also provided with a shielding portion 414 shielding above the first main machine air inlet 412 or the first main machine air outlet 413, and the shielding portion 414 opens laterally outward, and more preferably, as shown in Figure 4As shown, both the air inlet 412 and the air outlet 413 of the first host are provided with shielding parts 414.

[0052] By providing a shielding part 414 in the mounting slot 411 that shields the air inlet 412 or the air outlet 413 of the first host, and the shielding part 414 opening outwards to the side, the air inlet 412 or the air outlet 413 of the first host is shielded from the air above by the shielding part 414. This prevents the user from accidentally adding too much food into the cup 1, which could cause overflow during processing and enter the host 4 through the air inlet 412 or the air outlet 413 of the first host. This protects the components inside the host 4 and improves the user experience.

[0053] As a preferred embodiment of this application, such as Figure 5 , Figure 7 As shown, the bottom wall of the main unit housing 41 is provided with a second main unit air inlet 415 and a second main unit air outlet 416. The bottom wall of the main unit housing 41 is also provided with an inclined guide surface. The second main unit air inlet 415 or the second main unit air outlet 416 is located at the lowest position of the guide surface. Preferably, as shown... Figure 5 As shown, the second main unit air inlet 415 is located at the lowest position of the guide surface.

[0054] By providing a second main unit air inlet 415 and a second main unit air outlet 416 on the bottom wall of the main unit housing 41, airflow can enter the air intake duct through the second main unit air inlet 415, then enter the mounting cavity 31 through the first main unit air inlet 412 to dissipate heat from components such as the brushless motor 2, and then enter the air outlet duct through the first main unit air outlet 413, finally being discharged to the outside through the second main unit air outlet 416, thus completing the entire heat dissipation process. Simultaneously, the bottom wall of the main unit housing 41 is also provided with an inclined guide surface, and the second main unit air inlet 415 or the second main unit air outlet 416 is located at the lowest point of the guide surface. This allows the second main unit air inlet 415 or the second main unit air outlet 416 to function as both an air intake / exhaust point and a drainage hole, enhancing the functionality of the second main unit air inlet 415 or the second main unit air outlet 416 and eliminating the need for a separate drainage hole, thus further simplifying the overall structure of the machine.

[0055] As a preferred embodiment of this application, such as Figure 2 , Figure 3 As shown, the brushless motor 2 includes a housing 22 and a motor body 21 disposed within the housing 22. The heat dissipation channel includes a heat dissipation cavity 221 formed within the housing 22. The cup holder 3 is provided with a cup holder air inlet 32 ​​and a cup holder air outlet 33 communicating with the heat dissipation cavity 221.

[0056] By setting the heat dissipation channel to include a heat dissipation cavity 221 formed in the outer shell 22, and the cup holder 3 is provided with a cup holder air inlet 32 ​​and a cup holder air outlet 33 communicating with the heat dissipation cavity 221, the airflow enters the cup holder 3 through the cup holder air inlet 32, then enters the heat dissipation cavity 221 to dissipate heat from the motor body 21, and then exits the outer shell 22 and is discharged into the main unit 4 through the cup holder air outlet 33, thereby realizing the entire heat dissipation process.

[0057] Furthermore, such as Figure 3 As shown, the cup holder 3 is also provided with a second air guide shroud 7 that connects the outer shell 22 and the air inlet 32 ​​of the cup holder or connects the outer shell 22 and the air outlet 33 of the cup holder. More preferably, as shown in the figure... Figure 3 As shown, the second air guide shroud 7 is disposed between the cup holder air outlet 33 and the outer casing 22.

[0058] By providing a second air guide shroud 7 inside the cup holder 3, which connects the outer shell 22 with the air inlet 32 ​​of the cup holder or the outer shell 22 with the air outlet 33 of the cup holder, the airflow entering or exiting the cup holder 3 can be guided by the second air guide shroud 7, thereby ensuring the smooth flow of air inside the cup holder 3, which helps to improve the efficiency of gas flow and avoids the situation where the slow airflow rate leads to poor heat dissipation of the brushless motor 2.
