Description

Technical Field

[0001] This utility model belongs to the technical field of food processing machines, and in particular relates to a food processing machine with a changeable air duct. Background Technology

[0002] Food processors use a motor-driven blade assembly to stir or cut ingredients within the food container. Because the motor generates significant heat during prolonged operation, a cooling duct and impeller are necessary inside the casing for heat dissipation. However, different power levels of food processors have varying cooling requirements, and different users have different tolerances for noise levels. Therefore, the internal cooling ducts and impellers of different food processors vary. Currently, the internal cooling ducts of food processors are tightly coupled with the impeller type, requiring the independent development of custom duct components to adapt to different impeller types. This increases R&D costs, and changing impellers requires a complete overhaul of the duct housing, with modification costs reaching up to 40% of the original equipment price, resulting in poor compatibility. Furthermore, traditional duct designs suffer from thermodynamic efficiency bottlenecks, such as a single airflow path and low air intake, failing to efficiently dissipate heat from the food processor's interior. Therefore, there is an urgent need for a powerful heat dissipation structure that is compatible with multiple impeller types and optimizes airflow paths to systematically solve the problems of equipment compatibility and heat dissipation efficiency. Summary of the Invention

[0003] (a) Purpose of the utility model

[0004] To overcome the above shortcomings, the purpose of this utility model is to provide a food processing machine with a changeable air duct, so as to solve the technical problems of poor compatibility and insufficient heat dissipation efficiency of existing food processing machines.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A food processing machine with a variable air duct includes: a cup body; and a power base connected to the cup body. The power base includes: a housing with a first air vent, a second air vent, and a third air vent respectively opened from top to bottom on its side; an electrical mounting cavity with openings at the top and bottom inside; a motor assembly disposed within the electrical mounting cavity; a blade assembly disposed above the motor assembly and extending into the cup body; a centrifugal impeller or an axial impeller disposed at the lower end of the motor assembly; and a first air duct cover or a second air duct cover disposed within the housing and below the centrifugal impeller or axial impeller.

[0008] The first air duct cover connects the electrical installation cavity and the second air outlet, and can guide the air that enters the electrical installation cavity from the first and third air outlets to the second air outlet when the centrifugal impeller is installed in the food processing machine and the centrifugal impeller rotates;

[0009] The second air duct cover connects the electrical installation cavity and the third air outlet, and can guide the air entering the electrical installation cavity from the first and second air outlets to the third air outlet when the axial flow impeller is installed on the food processing machine and the axial flow impeller rotates.

[0010] This application achieves rapid switching between centrifugal and axial flow impeller systems through the modular design of the first and second air duct covers. It is compatible with motors of different power (such as 500W to 1500W models) and food processing machines with different noise requirements. It does not require overall modification of the air duct structure, reducing modification costs by more than 40%. In centrifugal impeller mode, the third air inlet serves as an auxiliary air inlet, increasing the air intake of the enclosed cavity and reducing eddy current interference, improving heat dissipation and reducing noise during exhaust. In axial flow impeller mode, the second air inlet serves as an auxiliary air inlet, increasing the air intake of the enclosed cavity and eliminating airflow recirculation areas, improving heat dissipation efficiency by 30% and enhancing environmental adaptability. Furthermore, the coordinated operation of multiple air inlets can maintain a stable air intake in low-pressure environments (such as at an altitude of 3000 meters), with the heat dissipation efficiency attenuation rate controlled within 20% and the coil temperature rise reduced by 15°C.

[0011] In some embodiments, there are multiple third air vents arranged around the edge of the housing;

[0012] The third air inlet of the ring array forms a 360° air intake channel, eliminating local airflow dead zones. In centrifugal impeller mode, the air intake uniformity is improved by 50%. The decentralized air inlet design can also reduce the risk of foreign objects being sucked in at a single point. At the same time, through the principle of airflow phase cancellation, the operating noise is reduced by 3-5dB.

[0013] In some embodiments, the upper end of the first air duct cover is connected to the electrical installation cavity, the lower end forms an annular receiving cavity, and the lower end side has an air guide port that is connected to the second air outlet.

[0014] The structure of the first air duct cover is optimized, and the annular receiving cavity forms an arc-shaped transition structure, which efficiently converts the axial airflow into radial airflow, increases the airflow velocity by 20%, and achieves a heat dissipation efficiency of 95W / ℃. The first air duct cover can also reduce airflow leakage and increase the air volume utilization rate by 18%.

[0015] In some embodiments, the upper end of the second air duct cover is connected to the electrical mounting cavity, and the lower end is inclined to form an air guide wall that extends to the inner sidewall of the housing and is located between the second and third air outlets;

[0016] The second duct cover forces the axial airflow of the axial impeller to diffuse and discharge from the third air outlet, making it suitable for use with axial impellers. In addition, the slanted structure of the second duct cover can also avoid energy loss caused by the collision between the direct exhaust flow and the top wall of the casing, and improve the wind pressure utilization rate by 25%.

[0017] In some embodiments, a sleeve is provided on the bottom wall of the inner shell, the lower end of the first air duct cover extends downward to form a first insert post inserted into the sleeve, and the lower end of the second air duct cover extends downward to form a second insert post inserted into the sleeve.

[0018] The structure of the sleeve and the first insert can realize the axial limiting and radial fixing of the first air duct cover, which can realize quick positioning and installation, shorten the assembly time, and improve maintenance efficiency by 60%. In addition, the structure of the sleeve and the first insert is conducive to improving seismic stability and preventing the first air duct cover from loosening and affecting the air guiding effect. The second insert of the second air duct cover shares the interface with the first insert, reducing the modification of the shell structure and reducing the mold development cost by 30%.

[0019] In some embodiments, a sleeve is provided on the bottom wall of the housing, and the size of the upper and lower openings of the electrical mounting cavity is less than or equal to the exposed size of the coil of the motor assembly;

[0020] Optimize the size of the upper and lower openings of the electrical mounting cavity to avoid excessively large openings that would reduce the internal air pressure and suction force of the electrical mounting cavity, causing the airflow curve to diverge and preventing concentrated heat dissipation of the motor coils.

[0021] Another aspect of this application provides a centrifugal cooling food processor, comprising: a cup body, and a power base connected to the cup body. The power base includes: a housing, with a first air vent, a second air vent, and a third air vent respectively opened from top to bottom on the side, an electrical mounting cavity with openings at the top and bottom inside, a motor assembly disposed in the electrical mounting cavity, a blade assembly disposed at the upper end of the motor assembly and extending into the cup body, a centrifugal impeller disposed at the lower end of the motor assembly, and a first air duct cover disposed inside the housing and located below the centrifugal impeller. The first air duct cover connects the electrical mounting cavity and the second air vent, and can guide the air entering the electrical mounting cavity from the first and third air vents to the second air vent for discharge when the centrifugal impeller is installed in the food processor and the centrifugal impeller rotates.

[0022] The third air inlet of the food processing machine of this application serves as an auxiliary air inlet, which increases the air intake volume. The air duct structure optimized for centrifugal impellers can support continuous operation of high-power motors, with less temperature rise in the coils, thus extending the service life of motor components.

[0023] In some embodiments, the upper end of the first air duct cover is connected to the electrical installation cavity, the lower end forms an annular receiving cavity, and the lower end side has an air guide port that connects to the second air outlet.

[0024] This application also provides an axially heat-dissipating food processing machine, including: a cup body, a power base connected to the cup body, the power base including: a shell, a first air vent, a second air vent and a third air vent respectively opened from top to bottom on the side, an electrical mounting cavity with openings at the top and bottom inside, a motor assembly disposed in the electrical mounting cavity, a blade assembly disposed at the upper end of the motor assembly and extending into the cup body, an axial flow impeller disposed at the lower end of the motor assembly, and a second air duct cover disposed inside the shell and located below the axial flow impeller, wherein the second air duct cover connects the electrical mounting cavity and the third air vent, and can guide the air entering the electrical mounting cavity from the first and second air vents to the third air vent for discharge when the axial flow impeller is installed in the food processing machine and the axial flow impeller rotates;

[0025] The second air inlet is converted into an auxiliary air inlet, increasing the air intake of the enclosed cavity and improving heat dissipation efficiency by 30%. At the same time, the axial air duct design of the axial impeller makes the airflow flow along the motor axis, reducing the kinetic energy loss caused by path bends. It forces the airflow to be concentrated and discharged from the third air inlet, forming a directional air curtain, effectively isolating the motor heat from being transferred to the side wall of the casing. It has high heat dissipation efficiency and is suitable for continuous operation of small and medium power motors.

[0026] In some embodiments, the upper end of the second air duct cover is aligned with the electrical mounting cavity, and the lower end is inclined to form an air guide wall that extends to the inner wall of the housing and is located between the second and third air outlets.

[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0039] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0040] like Figure 1-4 As shown, this food processor includes: a cup body 2, and a power base connected to the cup body 2. Specifically, the power base includes: a housing 1, with a first air vent 101, a second air vent 102, and a third air vent 103 sequentially opened on the side of the housing 1 from top to bottom. An electrical mounting cavity 104, running vertically through the housing 1, is formed inside the housing 1 for mounting a motor assembly 8. The upper end of the motor assembly 8 is connected to a blade assembly 3 (which extends into the cup body 2 to cut food), and the lower end is connected to an impeller. Depending on the usage requirements, the impeller can be a centrifugal impeller 4 or an axial flow impeller 5, and a first air duct cover 6 or a second air duct cover 7 can be installed accordingly to achieve switching of air duct modes.

[0041] Specifically, the centrifugal impeller 4 drives the air to swing in all directions, while the axial impeller 5 drives the air to flow axially.

[0042] The installation method of the first air duct cover 6 or the second air duct cover 7 is described in detail below:

[0043] Please see Figure 5 Centrifugal impeller 4 modes:

[0044] Centrifugal impeller 4 is installed at the lower end of the motor. The first air duct cover 6 is set inside the outer casing 1 and is connected to the lower end of the electrical mounting cavity 104. When the centrifugal impeller 4 rotates, under the action of wind pressure, the external cold airflow enters the outer casing 1 from the first air inlet 101 (main air inlet) and the third air inlet 103 (auxiliary air inlet). The airflow from the first air inlet 101 (main air inlet) directly enters the electrical mounting cavity 104 from the upper end. The airflow from the third air inlet 103 (auxiliary air inlet) flows upward and then enters the electrical mounting cavity 104 from the upper end. Both airflows flow through the electrical mounting cavity 104 and carry away the heat generated by the motor assembly 8, turning it into hot air. After the hot air enters the first air duct cover 6, the hot air is thrown to all sides by centrifugal force and is guided by the first air duct cover 6 to be discharged from the second air inlet 102.

[0045] Please see Figure 6 Axial flow impeller, mode 5:

[0046] An axial impeller 5 is mounted at the lower end of the motor, and a second air duct cover 7 is disposed inside the housing 1 and connected to the lower end of the electrical mounting cavity 104. When the axial impeller 5 rotates, external cold airflow enters the housing 1 from the first air inlet 101 and the second air inlet 102, and enters the electrical mounting cavity 104 from the upper end. The two airflows flow through the electrical mounting cavity 104 simultaneously, carrying away the heat generated by the motor assembly 8 and turning it into hot air. Since the axial impeller 5 drives the airflow axially, the hot air flows axially from the electrical mounting cavity 104 to the second air duct cover 7, and is discharged from the third air inlet 103 under the guidance of the second air duct cover 7.

[0047] Preferably, the third air vent 103 is designed in a ring shape. Specifically, the third air vent 103 consists of multiple small circular holes that are evenly distributed around the bottom edge of the outer casing 1.

[0048] Specifically, the third air outlet 103 is designed in a ring shape, which can bring the following effects in both centrifugal impeller mode 4 and axial impeller mode 5:

[0049] In centrifugal impeller mode 4, the third air inlet 103 serves as an auxiliary air inlet, and its 360° annular layout eliminates dead air angles, improving air intake uniformity by 50%.

[0050] In axial impeller mode 5, the third air outlet 103 serves as the main exhaust outlet. The decentralized design reduces the risk of foreign objects being sucked in (such as food residue), while noise is reduced by 3-5dB through airflow phase cancellation.

[0051] Specifically, the first air duct cover 6 has a structure in which the upper end is sealed and connected to the electrical installation cavity 104, and the lower end forms an annular receiving cavity with an air guide opening on its side (the width of which is 80% of the diameter of the second air outlet 102). The annular receiving cavity converts the axial airflow of the centrifugal impeller 4 into radial flow, increasing the wind speed by 20% and achieving a heat dissipation efficiency of 95W / ℃.

[0052] Specifically, the bottom of the outer shell 1 is provided with a sleeve, and the lower end of the first air duct cover 6 extends out with a first insert post. The assembly of the first air duct cover 6 can be completed after the first insert post is inserted into the sleeve.

[0053] Preferably, the gap between the first insert and the sleeve is 0.1mm, which ensures smooth installation and prevents loosening during operation.

[0054] Specifically, the upper end of the second air duct cover 7 is connected to the electrical mounting cavity 104, and the lower end extends into an inclined (15° angle) air guide wall, with its end tightly abutting the inner wall of the outer casing 1. The inclined air guide wall forces the axial airflow of the axial impeller 5 to the third air outlet 103, reducing energy loss caused by path bends. The end of the air guide wall is located between the second air outlet 102 and the third air outlet 103, preventing airflow backflow and improving air pressure utilization by 25%. Specifically, the bottom of the second air duct cover 7 is provided with a second insert post, which is inserted into the sleeve of the outer casing 1 for fixation.

[0055] Specifically, the heat-generating element of the motor assembly 8 is mainly the coil, which needs to be cooled in a concentrated manner. The heat on the coil is quickly carried away by airflow. Preferably, this application has openings 1041 at the upper and lower ends of the side of the electrical mounting cavity 104. The longitudinal diameter (d) of the opening 1041 should not be too large. It needs to be smaller than or equal to the exposed size of the coil of the motor assembly 8, just enough to cool the coil. If the opening 1041 is too large, it will affect the negative pressure inside the electrical mounting cavity 104, resulting in a decrease in the suction force inside the electrical mounting cavity 104 and a diverging airflow curve, which will not be able to concentrate the heat dissipation of the coil of the motor assembly 8.

[0056] Specifically, the practical application effects were obtained through experiments:

[0057] Centrifugal impeller 4 modes: Suitable for high-power motors (such as 1500W juicers), the dual air inlet design increases the air volume by 20%, the heat dissipation efficiency reaches 95W / ℃, the motor temperature rise is reduced by 15℃, and the noise generated during operation is low.

[0058] Axial impeller with 5 modes: compatible with small and medium power motors (such as 800W mixers), with a short axial airflow path and noise ≤60dB, suitable for home use.

[0059] Through the above design, this food processing machine achieves rapid switching of air duct structure, taking into account efficient heat dissipation, low noise and low-cost maintenance.

[0060] Another aspect of this application provides a centrifugal cooling food processor, comprising: a cup body 2, and a power base connected to the cup body 2. The power base includes: a housing 1, with a first air vent 101, a second air vent 102, and a third air vent 103 respectively opened from top to bottom on the side, an electrical mounting cavity 104 with upper and lower openings 1041 inside, a motor assembly 8 disposed in the electrical mounting cavity 104, a blade assembly 3 disposed at the upper end of the motor assembly 8 and extending into the cup body 2, a centrifugal impeller 4 disposed at the lower end of the motor assembly 8, and a first air duct cover 6 covered inside the housing 1 and located below the centrifugal impeller 4. The first air duct cover 6 connects the electrical mounting cavity 104 and the second air vent 102, and can guide the air entering the electrical mounting cavity 104 from the first and third air vents 101 and 103 to the second air vent 102 for discharge when the centrifugal impeller 4 is installed in the food processor and the centrifugal impeller 4 rotates.

[0061] Specifically, the upper end of the first air duct cover 6 is connected to the electrical installation cavity 104, the lower end forms an annular receiving cavity, and the lower side has an air guide port that is connected to the second air outlet 102.

[0062] This application also provides an axially heat-dissipating food processing machine, including: a cup body 2, and a power base connected to the cup body 2. The power base includes: a housing 1, with a first air vent 101, a second air vent 102, and a third air vent 103 respectively opened from top to bottom on the side, an electrical installation cavity 104 with upper and lower openings 1041 inside, a motor assembly 8 disposed in the electrical installation cavity 104, a blade assembly 3 disposed at the upper end of the motor assembly 8 and extending into the cup body 2, an axial flow impeller 5 disposed at the lower end of the motor assembly 8, and a second air duct cover 7 disposed inside the housing 1 and located below the axial flow impeller 5. The second air duct cover 7 connects the electrical installation cavity 104 and the third air vent 103, and can guide the air entering the electrical installation cavity 104 from the first and second air vents 101 and 102 to the third air vent 103 for discharge when the axial flow impeller 5 is installed in the food processing machine and the axial flow impeller 5 rotates.

[0063] Specifically, the upper end of the second air duct cover 7 is connected to the electrical installation cavity 104, and the lower end is inclined to form an air guide wall that extends to the inner wall of the outer casing 1 and is located between the second and third air outlets 102 and 103.
