Description

Technical Field

[0001] This utility model belongs to the field of kitchen appliance technology, specifically relating to a food processing machine. Background Technology

[0002] Traditional food processors typically consist of a mixing cup, a main unit, and a motor built into the main unit. To effectively dissipate heat from the motor, the motor body has an air inlet and an air outlet. The main unit also has corresponding air intake channels connecting the air inlet to the outside and air outlet channels connecting the air outlet to the outside. During operation, airflow enters the motor through the air intake channels and inlet for heat exchange, and then exits through the air outlet and air outlet channels to the outside, thus completing the motor's heat dissipation cycle. In traditional food processing machines of this type, such as patent application number CN202420502143.1, the heating plate at the bottom of the mixing cup is placed horizontally, and the motor body is set horizontally. The air outlet of the motor is located on the side of the motor body. At this time, the inlet of the air outlet channel is usually directly opposite the air outlet of the motor. The cooling airflow enters the air outlet channel directly from the air outlet and is discharged. Although it can ensure the airflow efficiency to a certain extent, this airflow method causes the airflow to directly impact the air outlet channel when it is discharged from the air outlet, generating noise. The airflow carries the noise and is discharged directly to the outside, resulting in high cooling noise.

[0003] With continuous technological advancements, some food processors now feature tilted heating plates to reduce the blind spot in the mixing area near the blade shaft. Correspondingly, the motor is also tilted, with its shaft perpendicularly passing through the heating plate and connecting to the grinding blade. Naturally, the air outlet on the side of the motor is also tilted downwards or upwards. However, if traditional cooling methods are used, the airflow is obstructed as it enters the exhaust channel, resulting in insufficient airflow and reduced cooling efficiency. Furthermore, the airflow directly impacts the exhaust channel, generating noise, and this noise is also transmitted directly through the exhaust channel, perpetuating the problem of high noise levels during cooling. Utility Model Content

[0004] This utility model provides a food processing machine to solve the technical problem that when the motor is tilted inside the machine base, the airflow discharged from the motor outlet directly impacts the air duct, causing significant noise.

[0005] The technical solution adopted in this utility model is as follows: This utility model provides a food processing machine, including a main unit, a motor disposed within the main unit, an air inlet channel, and an air outlet channel. The motor has an air inlet and a side-opening air outlet. The air outlet is located below the air inlet. The air inlet is connected to the outside through the air inlet channel, and the air outlet is connected to the outside through the air outlet channel. The motor is inclinedly disposed on the main unit, and the air outlet is inclined downward. The air outlet channel is located on one side of the motor, and the air outlet is set lower than the inlet of the air outlet channel. A buffer channel is connected between the air outlet and the inlet of the air outlet channel.

[0006] This utility model provides a food processing machine. By setting the air outlet lower than the inlet of the air outlet channel, and connecting a buffer channel between the inlet of the air outlet channel and the air outlet, when the motor is working, the airflow enters the motor from the air inlet channel and completes heat exchange. The airflow discharged from the air outlet must flow from bottom to top along the buffer channel. During the airflow process, the buffer channel not only guides the cooling airflow, but also allows the cooling airflow to naturally consume some kinetic energy during its upward movement. The reduction of kinetic energy reduces the collision force between the cooling airflow and the inner wall of the buffer channel and the inner wall of the air outlet channel, thereby reducing the noise generated by the collision of the cooling airflow and achieving the beneficial effect of reducing the cooling noise of the food processing machine.

[0007] In a preferred embodiment, the inlet of the air outlet channel and the air outlet are located on the same side of the axis of the motor, and the inlet of the air outlet channel and the air outlet are laterally offset.

[0008] By placing the air outlet inlet and the motor outlet on the same side of the motor axis, the increased internal space required due to the need for additional detours caused by their different locations on the motor is avoided, effectively controlling the overall size of the food processor. Simultaneously, the horizontal misalignment naturally creates a buffer space, extending the airflow path for heat dissipation. Therefore, the buffer channel not only guides the airflow from bottom to top vertically but also provides buffering along the horizontal direction, further buffering the airflow from the outlet to the air outlet inlet. This reduces noise generated by direct impact on the air outlet wall without requiring additional complex structures to achieve the buffering function, improving noise reduction and facilitating miniaturization of the main unit.

[0009] In a preferred embodiment, the buffer channel includes a first air guide section, a second air guide section, and a third air guide section connected in sequence. The first air guide section is connected to the air outlet and extends downward at an angle along the inclined direction of the air outlet. The second air guide section is connected to the first air guide section and extends upward. The third air guide section extends horizontally from the second air guide section to connect with the air outlet channel.

[0010] By setting the buffer channel as a first air guide section, a second air guide section, and a third air guide section connected in sequence, a three-section structure is formed. The first air guide section of the buffer channel connects with the motor air outlet and extends downward along its inclined direction. The first air guide section can conform to the inclined angle of the air outlet to guide the airflow and avoid obstruction of airflow discharge due to sudden changes in the direction of the connection position, ensuring that the airflow flows smoothly out of the motor, thereby ensuring exhaust efficiency and achieving continuous and efficient heat dissipation of the motor. The second air guide section follows the first air guide section and extends upward, so that the kinetic energy of the airflow is naturally weakened during the upward flow, initially reducing the impact force of the airflow and achieving the purpose of noise reduction. The third air guide section extends horizontally and connects smoothly with the air outlet channel, further ensuring the continuity of airflow and reducing airflow obstruction caused by poor exhaust connection. Meanwhile, since the first, second, and third air guide sections form a corner, the airflow generates turbulence when passing through the corner. During the turbulence, the interaction of airflow further consumes kinetic energy, which greatly reduces the force and frequency of the airflow colliding with the side walls of the buffer channel and the air outlet channel. Therefore, the structure of the three-section buffer channel effectively reduces the noise generated during the airflow process while ensuring smooth exhaust and efficient heat dissipation, thus achieving a simultaneous improvement in exhaust efficiency and noise reduction effect.

[0011] In a preferred embodiment, the cross-sectional area of ​​the third air guide section is larger than the cross-sectional area of ​​the second air guide section.

[0012] Because the airflow velocity is inversely proportional to the cross-sectional area of ​​the flow during the flow of incompressible air, that is, the airflow velocity will decrease accordingly when the cross-sectional area of ​​the flow increases. Therefore, when the airflow passes through the second guide section and enters the third guide section with an increased cross-sectional area, the airflow velocity will decrease. The decrease in velocity directly weakens the collision force and frequency between the airflow and the side wall of the third guide section, thereby reducing the noise generated by the airflow impacting the side wall of the duct. In a preferred embodiment, the third air guide section includes a connecting section and a docking section communicating with the connecting section. The cross-sectional area of ​​the docking section is larger than that of the connecting section, and the docking section is connected to the air outlet channel.

[0013] The third air guide section is used to set up a connecting section and a docking section connected to the connecting section. The cross-sectional area of ​​the docking section is larger than that of the connecting section. When the airflow passing through the third air guide section enters the docking section with the increased cross-sectional area, the airflow velocity will decrease accordingly, reducing the airflow collision force and frequency, thereby reducing the noise generated by the airflow impacting the side wall of the air duct in the third air guide section.

[0014] In a preferred embodiment, the buffer channel is a flexible silicone element.

[0015] By using flexible silicone components, which possess excellent flexibility and elasticity, when airflow flows within the buffer channel and collides with the channel's inner wall, the flexible silicone wall does not generate a strong, hard impact with the airflow like rigid materials. Instead, it absorbs some of the energy generated by the airflow collision through its own elastic deformation, further reducing the noise caused by the airflow impact and creating a cumulative noise reduction effect. The flexible buffer channel is also more adaptable to minor dimensional deviations or installation angle errors that may exist between the motor's air outlet and the air outlet channel inlet during assembly. It can achieve a tight connection without strict dimensional matching, reducing assembly difficulty, improving assembly efficiency and adaptability, enhancing sealing and connection, and ensuring smooth exhaust of the motor's heat dissipation airflow.

[0016] In a preferred embodiment, the motor is provided with a plurality of air inlets spaced apart along its circumference, and at least a portion of the air inlets are projected toward the outlet of the air inlet channel onto the outlet of the air inlet channel.

[0017] By setting multiple air inlets at intervals around the motor, multi-directional air intake is formed, increasing the total amount of outside cold air entering the motor and improving the motor's heat dissipation efficiency. At least some of the air inlets' projections coincide with the projections of the air intake channel's outlet. Therefore, the air inlets can directly and efficiently receive the airflow delivered from the air intake channel, avoiding the loss or waste of cold airflow and achieving efficient heat dissipation of the motor.

[0018] In a preferred embodiment, the outlet of the air inlet channel and the inlet of the air outlet channel are located on opposite sides of the motor.

[0019] In a preferred embodiment, the outlet of the air inlet channel and the inlet of the air outlet channel are located on adjacent sides of the motor, and a control board is also provided inside the main unit, the control board and the air inlet channel being located on the same side of the motor.

[0020] Whether the air inlet and outlet are located on opposite sides of the motor or adjacent sides, external airflow can effectively circulate and cool the motor's interior. The first method results in a more direct airflow path, less loss, and higher cooling efficiency. The second method, arranging the air inlet and outlet on adjacent sides of the motor, avoids excessive length of the main unit along the motor's cooling path. Furthermore, the control board and the air inlet are located on the same side of the motor, allowing for efficient use of the internal space, improving the main unit's compactness, and facilitating miniaturization.

[0021] In a preferred embodiment, the main unit includes an upper housing and a lower housing that enclose a mounting cavity, and a mounting bracket for fixing the motor is also provided inside the mounting cavity. The mounting bracket and the lower housing enclose the air outlet channel.

[0022] By setting up a mounting bracket, the motor is fixed in place, and the mounting bracket and the lower housing form an air outlet channel. There is no need to design and install a complete air outlet channel component separately, which simplifies the number of parts and assembly process of the whole machine. The structure of the air outlet channel is stable, ensuring the motor's heat dissipation efficiency and exhaust noise reduction effect. Attached Figure Description

[0026] Many specific details are set forth in the following description to provide a full understanding of the present invention.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0030] like Figure 1 , Figure 2As shown, in one embodiment, this utility model provides a food processing machine, including a main unit 10, a motor 20 disposed within the main unit 10, an air inlet channel 30, and an air outlet channel 40. The motor 20 has an air inlet 21 and a side-opening air outlet 22, with the air outlet 22 located below the air inlet 21. The air inlet 21 communicates with the outside through the air inlet channel 30, and the air outlet 22 communicates with the outside through the air outlet channel 40. The motor 20 is inclinedly disposed on the main unit 10, as shown in the figure. Figure 2 , 3 As shown, the air outlet 22 is tilted downwards, the air outlet channel 40 is located on one side of the motor 20, the air outlet 22 is set lower than the inlet 401 of the air outlet channel, and a buffer channel 50 is connected between the air outlet 22 and the inlet 401 of the air outlet channel.

[0031] like Figure 1 As shown, it should be noted that the food processing machine provided by this utility model preferably also includes a stirring cup 60 fixedly or detachably installed on the main unit 10. The bottom of the stirring cup 60 is provided with an inclined heating plate 61. A crushing blade 62 is provided inside the stirring cup 60. The crushing blade 62 is inserted into the heating plate 61. The motor 20 drives the crushing blade 62 to rotate to crush the material in the stirring cup and prepare soy milk.

[0032] This utility model provides a food processing machine. By setting the air outlet 22 lower than the inlet of the air outlet channel 40, and connecting the inlet of the air outlet channel 40 and the air outlet 22 with a buffer channel 50, when the motor 20 is working, the airflow enters the motor 20 from the air inlet channel 30 and the air inlet 21 to complete heat exchange. The hot airflow discharged from the air outlet 22 must flow from bottom to top along the buffer channel 50. The airflow direction is as follows: Figure 3 As shown by the dotted arrow, during the airflow process, the buffer channel 50 not only guides the airflow, but also allows the airflow to naturally consume some kinetic energy during its upward movement. The reduction of kinetic energy will reduce the collision force between the airflow and the inner wall of the buffer channel 50 and the inner wall of the air outlet channel 40, thereby reducing the noise generated by the airflow collision and achieving the beneficial effect of reducing the exhaust noise of the food processing machine.

[0033] like Figure 4 As shown, preferably, the buffer channel 50 is a flexible silicone component.

[0034] By using flexible silicone components, which possess excellent flexibility and elasticity, when airflow flows within the buffer channel 50 and collides with the inner wall of the channel, the flexible silicone wall will not produce a strong hard impact with the airflow like a rigid material. Instead, it can absorb some of the energy generated by the airflow collision through its own elastic deformation, further weakening the noise caused by the airflow impact and creating a superposition of noise reduction effects. The flexible buffer channel 50 is more adaptable to the slight dimensional deviations or installation angle errors that may exist between the air outlet 22 of the motor 20 and the inlet of the air outlet channel 40 during assembly. It can achieve a tight connection without strict dimensional matching, reducing assembly difficulty, improving assembly efficiency and adaptability, enhancing sealing and connection, and enabling the smooth discharge of heat dissipation airflow from the motor 20.

[0035] Of course, it is understandable that the buffer channel 50 may be a rigid plastic part. Preferably, a first sealing ring is provided between the buffer channel and the air outlet of the motor; and a second sealing ring is provided between the buffer channel and the air outlet channel.

[0036] like Figure 3 As shown, in a preferred embodiment, the inlet 401 of the air outlet channel and the outlet 22 are located on the same side of the axis of the motor 20, and the inlet 401 of the air outlet channel and the outlet 22 are laterally offset.

[0037] By placing the inlet of the air outlet duct 40 and the air outlet 22 of the motor 20 on the same side of the motor 20 axis, the increased internal space occupied by the equipment due to the need to plan additional detour channels because they are located on different sides of the motor 20 can be avoided, effectively controlling the overall volume of the food processing machine. At the same time, the staggered arrangement of the two in the horizontal direction can naturally reserve buffer space in the horizontal space, extending the airflow path. Therefore, the buffer channel 50 not only guides the airflow from bottom to top in the vertical space, but also buffers and guides it along the horizontal space, thereby further buffering the airflow flowing from the air outlet 22 to the inlet of the air outlet duct 40, reducing the noise generated by the airflow directly impacting the wall of the air outlet duct 40, and without the need to add an additional complex structure to achieve the buffering function. While improving the noise reduction effect, it is also conducive to the miniaturization of the main unit 10.

[0038] like Figure 4 As shown, in a preferred embodiment, the buffer channel 50 includes a first air guide section 51, a second air guide section 52, and a third air guide section 53 connected in sequence. The first air guide section 51 is connected to the air outlet 22 and extends downward at an angle along the inclined direction of the air outlet 22. The second air guide section 52 is connected to the first air guide section 51 and extends upward. The third air guide section 53 extends horizontally from the second air guide section 52 to connect with the air outlet channel 40.

[0039] Combination Figure 3 , 4As shown, preferably, the cross-sectional area of ​​the third air guide section 53 is larger than the cross-sectional area of ​​the second air guide section 52. More preferably, the third air guide section 53 includes a connecting section 531 and a docking section 532 communicating with the connecting section 531, the cross-sectional area of ​​the docking section 532 is larger than the cross-sectional area of ​​the connecting section 531, and the docking section 532 is connected to the air outlet duct 40.

[0040] Of course, it is understandable that, in practice, the third air guide section can be a section of equal diameter with a uniform cross-sectional area, and optionally, the cross-sectional area of ​​the second air guide section 52 is smaller than the average cross-sectional area of ​​the third air guide section 53.

[0041] By setting the buffer channel 50 as a first air guide section 51, a second air guide section 52, and a third air guide section 53 connected in sequence, a three-section structure is formed. The first air guide section 51 of the buffer channel 50 is connected to the air outlet 22 of the motor 20 and extends downward along its inclined direction. The first air guide section 51 can conform to the inclined angle of the air outlet 22 to guide the airflow and avoid obstruction of the airflow due to sudden changes in the direction of the connection position, ensuring that the airflow flows smoothly out of the motor 20, thereby ensuring the exhaust efficiency and realizing the continuous and efficient heat dissipation of the motor 20. The second air guide section 52 receives the first air guide section 51 and extends upward, so that the kinetic energy of the airflow is naturally weakened during the upward flow, initially reducing the impact force of the airflow and achieving the purpose of noise reduction. The third air guide section 53 extends horizontally and connects smoothly with the air outlet channel 40, further ensuring the continuity of the airflow and reducing the airflow obstruction caused by poor exhaust connection. Meanwhile, since the first guide section 51, the second guide section 52 and the third guide section 53 form a corner, the airflow generates turbulence when passing through the corner. During the turbulence process, the interaction of airflow further consumes kinetic energy, which greatly reduces the force and frequency of the airflow colliding with the side walls of the buffer channel 50 and the air outlet channel 40. Therefore, the structure of the three-section buffer channel 50 effectively reduces the noise generated during the airflow process while ensuring smooth exhaust and efficient heat dissipation, thus achieving a simultaneous improvement in exhaust efficiency and noise reduction effect.

[0042] Because the airflow velocity is inversely proportional to the cross-sectional area of ​​the flow path during the flow of incompressible air, meaning that the airflow velocity decreases as the cross-sectional area increases, the airflow velocity decreases when the airflow passes through the second guide section 52 and enters the third guide section 53 with its increased cross-sectional area. This decrease in velocity directly weakens the collision force and frequency between the airflow and the sidewall of the third guide section 53, thereby reducing the noise generated by the airflow impacting the sidewall of the duct. Similarly, by using the third guide section 53 to set up a connecting section 531 and a docking section 532 connected to the connecting section 531, with the cross-sectional area of ​​the docking section 532 being larger than that of the connecting section 531, the airflow velocity decreases when the airflow passes through the third guide section 53 and enters the docking section with its increased cross-sectional area. This reduces the collision force and frequency of the airflow, thereby reducing the noise generated by the airflow impacting the sidewall of the duct within the third guide section 53.

[0043] This utility model does not limit the specific structure and arrangement of the air inlet and outlet channels, for example, such as Figure 5 , 6 As shown, in a preferred embodiment, the main unit 10 includes an upper housing 11 and a lower housing 12 that enclose a mounting cavity. The mounting cavity is also provided with a mounting bracket 13 for fixing the motor 20. The mounting bracket 13 and the lower housing 12 enclose an air outlet channel 40. More preferably, the mounting cavity is also provided with an air inlet bracket 15. The air inlet bracket 15 and the lower housing 12 enclose an air inlet channel 30.

[0044] By setting up the mounting bracket 13, the motor 20 is fixed in place. At the same time, the mounting bracket 13 and the lower housing 12 form an air outlet channel 40. There is no need to design and install a complete air outlet channel 40 separately, which simplifies the number of parts and assembly process of the whole machine. The structure of the air outlet channel 40 is stable, ensuring the heat dissipation efficiency of the motor 20 and the ventilation and noise reduction effect.

[0045] Preferably, such as Figure 5 As shown, the air inlet 301 is located in the lower housing 12, the air inlet 302 and the air outlet 401 are located on adjacent sides of the motor 20, respectively, and the air outlet 402 is located in the lower housing 12. A control board 14 is also provided inside the main unit 10. The control board 14 is fixed to the air inlet bracket 15, and the control board 14 and the air inlet 30 are located on the same side of the motor 20.

[0046] Of course, in another preferred embodiment, the outlet 302 of the air inlet channel and the inlet 401 of the air outlet channel 40 are located on opposite sides of the motor 20.

[0047] Whether the outlet of the air inlet channel 30 and the inlet of the air outlet channel 40 are located on opposite sides of the motor 20, or on adjacent sides of the motor 20, the external airflow can achieve a circulating cooling effect on the inside of the motor 20. The first method results in a more direct airflow path, less loss, and higher cooling efficiency. The second method, arranging the air inlet channel 30 and the air outlet channel 40 on adjacent sides of the motor 20, avoids making the main unit 10 too long along the heat dissipation path of the motor 20. Simultaneously, with the control board and air inlet channel 30 located on the same side of the motor 20, the internal space of the main unit 10 can be rationally utilized, improving its compactness and facilitating miniaturization design.

[0048] like Figure 5As shown, in a preferred embodiment, the motor 20 has a plurality of air inlets 21 spaced apart along its circumference, and at least some of the air inlets 21 are projected toward the outlet of the air inlet channel 30 onto the outlet of the air inlet channel 30. Specifically, in this embodiment, the motor 20 has a downwardly positioned air inlet 21, and the projection of the downwardly positioned air inlet 21 toward the outlet of the air inlet channel 30 is located on the outlet 302 of the air inlet channel.

[0049] By setting multiple air inlets 21 at intervals around the motor 20, multi-directional air intake is formed, increasing the total amount of outside cold air entering the motor 20 and improving the heat dissipation efficiency of the motor 20. At least some of the air inlets 21 have projections that coincide with the projections of the air intake channel 30 outlet. Therefore, the air inlets 21 can directly and efficiently receive the airflow delivered from the air intake channel 30, avoiding the loss or waste of cold airflow and achieving efficient heat dissipation of the motor 20.
