Description

Technical Field

[0001] The utility model relates to the technical field of household electrical appliances, in particular to a food processing machine with stable operation. Background Art

[0002] Existing food processors typically include a main unit and a cup assembly with a built-in stirring element. The series-wound motor in the main unit is connected to the stirring element through a transmission mechanism. When using the food processor to process food, the user places the food in the cup assembly, and the stirring element, driven by the series-wound motor, rotates at high speed to grind the food. However, because series-wound motors are noisy during operation, some manufacturers replace them with brushless motors to reduce the noise level of the entire machine. However, as the size of brushless motors decreases, especially the axial size, the distance between the stator and rotor in the brushless motor and the heating plate is greatly shortened. When the user uses the food processor, the heat generated by the heating plate is directly transferred to the brushless motor. As the brushless motor's temperature rises, the magnetism of the stator's permanent magnets and the rotor's coils weakens or even demagnetizes the permanent magnets, causing the brushless motor to rotate unstably or even unable to rotate. This, in turn, prevents the user from using the food processor normally to process food, seriously affecting the consumer experience. Utility Model Content

[0003] The purpose of the utility model is to provide a food processing machine with stable operation, so as to solve the problem in existing food processing machines that a large amount of heat from the heating plate is transferred to the brushless motor, resulting in a significant temperature rise of the brushless motor and causing the magnetism of the permanent magnet of the stator to weaken or even demagnetize.

[0004] To achieve the above-mentioned purpose, the utility model provides a food processor with stable operation, including a cup body assembly, the cup body assembly including a cup body with upper and lower openings, a stirring knife arranged in the cup body, and a heating plate with an opening at the lower end of the cup body, the food processor also includes a brushless motor arranged under the cup base and driving the stirring knife to rotate, the brushless motor includes a stator, a rotor and a bottom cover arranged under the stator and the rotor, the bottom cover is fixedly connected to the heating plate to form an installation cavity for accommodating the stator and the rotor, and an isolation member is also provided in the installation cavity to isolate the stator and the rotor from the heating plate.

[0005] The present application uses a brushless motor and takes advantage of the characteristics of the brushless motor to enable users to use the food processor to process food with lower motor rotation noise, thereby achieving noise reduction. At the same time, the brushless motor can achieve variable frequency control, so that the food processor can control the brushless motor to output different speeds according to different food ingredients and processing processes, which can achieve better and more complete processing effects on food ingredients and improve the taste of the food output. In addition, the brushless motor occupies less space, which helps to improve the compactness of the internal structure of the entire machine, reduce the space occupied by the food processor, and facilitate storage by users.

[0006] At the same time, the bottom cover is fixedly connected to the heating plate to form an installation cavity for accommodating the stator and the rotor. Compared with the existing method, which requires a separate motor cover, and fixes the stator and rotor between the motor cover and the bottom cover before fixing the entire brushless motor on the heating plate, this solution also realizes the assembly of the brushless motor when assembling the whole machine, simplifies the installation steps, and eliminates a motor cover, greatly simplifies the number of parts of the entire motor and the whole machine, helps to further improve the compactness of the internal structure of the whole machine, and at the same time compresses the axial height of the brushless motor and the heating plate, thereby making the axial height of the whole machine lower and thinner, further reducing the space occupied by the food processor.

[0007] In addition, an isolation piece is provided in the installation cavity to isolate the stator and rotor from the heating plate, so that the stator and rotor are isolated from the heating plate through the isolation piece, effectively reducing the heat transfer from the heating plate to the stator and rotor, thereby avoiding the large temperature rise of the stator's permanent magnet and the rotor's coil, which leads to performance degradation of both or even demagnetization of the permanent magnet, ensuring the magnetism of the stator and rotor, and then ensuring the stability of the brushless motor, which helps to extend the service life of the brushless motor and improve the user experience.

[0008] In a preferred implementation of a food processor with stable operation, the heating plate is provided with a fixing portion extending downward and fixedly connected to the bottom cover, and the isolating member is provided with a first avoidance hole for the fixing portion to pass through.

[0009] By providing a fixing portion extending downward and fixedly connected to the bottom cover on the heating plate, the heating plate is fixedly connected to the bottom cover through the fixing portion. At the same time, the isolating member is provided with a first avoidance hole for the fixing portion to pass through, so that the fixing portion can be fixedly connected to the bottom cover after passing through the first avoidance hole, thereby ensuring smooth matching and connection between the fixing portion and the bottom cover.

[0010] In a preferred implementation of a food processor with stable operation, the heating plate is provided with a limiting portion extending downward, and the limiting portion abuts against the stator for limiting position, and the isolating piece is provided with a second avoidance hole for the limiting portion to pass through.

[0011] By providing a downwardly extending limiting portion on the heating disk, and the limiting portion abutting against the stator for limiting, the heating disk limits the stator through the limiting portion, ensuring the stability of the stator position, and avoiding the low stability of the stator causing the stator to vibrate when the rotor rotates at high speed, resulting in unstable rotation or even wobbling of the entire brushless motor, which helps to improve the rotation stability of the entire brushless motor. At the same time, the isolating member is provided with a second avoidance hole for the limiting portion to pass through, ensuring that the limiting portion can limit the stator after passing through the second avoidance hole.

[0012] In a preferred implementation of a food processor with stable operation, the limiting portion is a plurality of limiting plates arranged at intervals along the circumference of the heating disk, and a heat dissipation port connecting the installation cavity with the outside is formed between two adjacent limiting plates.

[0013] By setting the limiting part as a plurality of limiting plates arranged at intervals along the circumference of the heating disk, a heat dissipation port connecting the installation cavity with the outside world is formed between two adjacent limiting plates. On the one hand, when the rotor rotates at high speed, the flow of ambient air driven by the rotor can improve the exchange of air around the stator and the rotor with the outside air through the heat dissipation port, thereby improving the heat dissipation efficiency of the rotor and the stator, further reducing the temperature rise of both, and helping to extend the service life of the brushless motor; on the other hand, compared with a full circle of limiting plates, the demoulding amount of the limiting plates can be reduced, thereby reducing production costs, and at the same time reducing the weight of the entire machine, so that users can more conveniently take the cup body assembly, thereby improving the user experience.

[0014] In a preferred implementation of the food processor with stable operation, the isolating member is fixed to the bottom wall of the heating plate.

[0015] By fixing the isolating member to the bottom wall of the heating plate, the heat generated by the heating plate can be directly isolated by the isolating member when it is conducted downward, effectively avoiding the presence of a gap between the isolating member and the heating plate, which causes the heat of the heating plate to be transferred to the air in the gap between the two, and then conducted to the stator and rotor by the air. This helps to further improve the thermal insulation effect of the isolating member and reduce the temperature rise of the stator and rotor.

[0016] In a preferred implementation of a stable food processor, the bottom wall of the heating plate is provided with a downwardly extending fixed column, the isolation piece is provided with a fixed hole vertically aligned with the fixed column, and the food processor also includes a connecting piece that passes through the fixing hole and is fastened to the fixed column.

[0017] By providing a downward extending fixing column on the bottom wall of the heating plate, and providing a fixing hole vertically aligned with the fixing column on the isolating piece, the food processor also includes a connecting piece, which passes through the fixing hole and is fastened to the fixing column, so that the isolating piece is connected and fixed to the heating plate through the connecting piece, thereby improving the stability of the connection between the isolating piece and the heating plate.

[0018] In a preferred implementation of a food processor with stable operation, the heating plate includes a base plate and a mounting portion arranged around the base plate and protruding downward for mounting a heating tube, and the isolating member includes a bottom surface adapted to the base plate and a step surface connected to the bottom surface and adapted to the mounting portion.

[0019] By setting the isolating member to include a bottom surface adapted to the base plate and a stepped surface connected to the bottom surface and adapted to the mounting portion, the isolating member can achieve all-round isolation of the heating plate from the stator and rotor. In particular, the setting of the stepped surface effectively isolates the heating tube from the components below, thereby further improving the thermal insulation effect of the isolating member, thereby further reducing the temperature rise of the stator and rotor, and improving the stability of the brushless motor.

[0020] In a preferred implementation of a food processor with stable operation, a heat dissipation gap is provided between the stator and the rotor and the isolating member.

[0021] By providing a heat dissipation gap between the stator and rotor and the isolator, the stator and rotor are further away from the isolator. Therefore, even if a large amount of heat is transferred from the heating plate to the isolator, the heat dissipation gap can reduce the heat transfer to the stator and rotor, which helps to further reduce the temperature rise of the stator and rotor. At the same time, the heat dissipation gap can also increase the air flow rate near the stator and rotor, so that more cold air can pass through the stator and rotor in unit time and achieve heat dissipation of both, which helps to improve the heat dissipation effect of the stator and rotor.

[0022] In a preferred implementation of a food processor with stable operation, the vertical width L of the heat dissipation gap satisfies: 3 mm ≤ L ≤ 20 mm.

[0023] By setting the vertical width L of the heat dissipation gap to satisfy: 3mm≤L≤20mm, the situation where the vertical width of the heat dissipation gap is too small, resulting in poor insulation and heat dissipation effects, causing high temperature rise of the stator and rotor and thus unstable operation, can be avoided; at the same time, the situation where the vertical width of the heat dissipation gap is too large, resulting in an excessively large axial dimension of the entire machine, causing it to occupy a large space and be difficult to pick up, can be avoided.

[0024] In a preferred implementation of a food processor with stable operation, the heating plate includes a heating tube, and the heating tube is located outside the installation cavity.

[0025] By arranging the heating tube outside the installation cavity, the heat generated by the heating tube can be isolated from the installation cavity under the obstruction of the bottom cover, thereby effectively reducing the heat conducted by the heating tube into the installation cavity, further achieving thermal insulation, and further reducing the temperature rise of the stator and rotor.

[0035] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific implementation methods disclosed below.

[0036] like Figures 1 to 5 As shown, the utility model provides a food processing machine with stable operation, including a cup body assembly, the cup body assembly including a cup body 1 with upper and lower openings, a stirring knife arranged in the cup body 1, and a heating plate 2 with an opening at the lower end of the cup body 1, the food processor also includes a brushless motor arranged under the cup base and driving the stirring knife to rotate, the brushless motor includes a stator 5, a rotor 4 and a bottom cover 7 arranged under the stator 5 and the rotor 4, the bottom cover 7 is fixedly connected to the heating plate 2 to form an installation cavity 6 for accommodating the stator 5 and the rotor 4, and an isolation member 3 is further provided in the installation cavity 6 for isolating the stator 5 and the rotor 4 from the heating plate 2.

[0037] The present application uses a brushless motor and takes advantage of the characteristics of the brushless motor to enable users to use the food processor to process food with lower motor rotation noise, thereby achieving noise reduction. At the same time, the brushless motor can achieve variable frequency control, so that the food processor can control the brushless motor to output different speeds according to different food ingredients and processing processes, which can achieve better and more complete processing effects on food ingredients and improve the taste of the food output. In addition, the brushless motor occupies less space, which helps to improve the compactness of the internal structure of the entire machine, reduce the space occupied by the food processor, and facilitate storage by users.

[0038] At the same time, the bottom cover 7 is fixedly connected to the heating plate 2 to form an installation cavity 6 for accommodating the stator 5 and the rotor 4. Compared with the existing method, which requires a separate motor cover, and fixes the stator 5 and the rotor 4 between the motor cover and the bottom cover 7 before fixing the entire brushless motor on the heating plate 2, this solution also realizes the assembly of the brushless motor when assembling the whole machine, simplifies the installation steps, and eliminates a motor cover, greatly simplifies the number of parts of the entire motor and the entire machine, helps to further improve the compactness of the internal structure of the whole machine, and at the same time compresses the axial height of the brushless motor and the heating plate 2, thereby making the axial height of the whole machine lower and thinner, further reducing the space occupied by the food processor.

[0039] In addition, an isolation member 3 is provided in the installation cavity 6 to isolate the stator 5 and the rotor 4 from the heating plate 2, so that the stator 5 and the rotor 4 are isolated from the heating plate 2 through the isolation member 3, effectively reducing the heat transfer from the heating plate 2 to the stator 5 and the rotor 4, thereby avoiding the situation where the permanent magnet of the stator 5 and the coil of the rotor 4 rise in temperature too much, resulting in performance degradation of both or even demagnetization of the permanent magnet, ensuring the magnetism of the stator 5 and the rotor 4, and thus ensuring the stability of the brushless motor, which helps to extend the service life of the brushless motor and enhance the user experience.

[0040] As a preferred embodiment of the present application, Figure 4 、 Figure 5 As shown, the heating plate 2 is provided with a fixing portion 23 extending downward and fixedly connected to the bottom cover 7, and the isolating member 3 is provided with a first avoidance hole 31 for the fixing portion 23 to pass through.

[0041] By providing a fixing portion 23 extending downward and fixedly connected to the bottom cover 7 on the heating plate 2, the heating plate 2 is fixedly connected to the bottom cover 7 through the fixing portion 23. At the same time, the isolating member 3 is provided with a first avoidance hole 31 for the fixing portion 23 to pass through, so that the fixing portion 23 can be fixedly connected to the bottom cover 7 after passing through the first avoidance hole 31, thereby ensuring smooth matching and connection between the fixing portion 23 and the bottom cover 7.

[0042] Specifically, the fixing part 23 is a fixing column extending downward, and a threaded hole is provided at the bottom of the fixing column. A fixing hole vertically aligned with the fixing part 23 is provided on the bottom cover 7. The screw passes through the fixing hole and is fastened in the threaded hole to achieve a fixed connection between the bottom cover 7 and the heating plate 2.

[0043] As a preferred embodiment of the present application, Figure 2 As shown, the heating plate 2 is provided with a limiting portion 21 extending downward, and the limiting portion 21 abuts against the stator 5 for limiting position, and the isolating member 3 is provided with a second avoidance hole 32 for the limiting portion 21 to pass through.

[0044] By providing a downwardly extending limiting portion 21 on the heating disk 2, and the limiting portion 21 abutting against the stator 5 for limiting, the heating disk 2 limits the stator 5 through the limiting portion 21, ensuring the stability of the position of the stator 5, and avoiding the low stability of the stator 5 causing the stator 5 to vibrate when the rotor 4 rotates at high speed, resulting in unstable rotation of the entire brushless motor or even wobbling, which helps to improve the stability of the rotation of the entire brushless motor. At the same time, the isolating member 3 is provided with a second avoidance hole 32 for the limiting portion 21 to pass through, ensuring that the limiting portion 21 can limit the stator 5 after passing through the second avoidance hole 32.

[0045] It should be noted that the present application does not specifically limit the structure of the limiting portion 21. As a preferred embodiment of the present application, Figure 2 As shown, the limiting portion 21 is a plurality of limiting plates arranged at intervals along the circumference of the heating disk 2, and a heat dissipation port 211 communicating with the mounting cavity 6 and the outside is formed between two adjacent limiting plates.

[0046] By configuring the limiting portion 21 as a plurality of limiting plates spaced circumferentially along the heating disk 2, a heat dissipation port 211 connecting the mounting cavity 6 with the outside world is formed between two adjacent limiting plates. On the one hand, when the rotor 4 rotates at high speed, the flow of ambient air driven by the rotor 4 can improve the exchange of air between the stator 5 and the air around the rotor 4 and the outside air through the heat dissipation port 211, thereby improving the heat dissipation efficiency of the rotor 4 and the stator 5, further reducing the temperature rise of both, and helping to extend the service life of the brushless motor; on the other hand, compared with a full circle of limiting plates, the demoulding amount of the limiting plates can be reduced, thereby reducing production costs, and at the same time reducing the weight of the entire machine, so that users can more conveniently take the cup body assembly, thereby improving the user experience.

[0047] It should be noted that the present application does not specifically limit the fixing position of the isolation member 3. As a preferred embodiment of the present application, Figure 2 As shown, the isolation member 3 is fixed to the bottom wall of the heating plate 2.

[0048] By fixing the isolating member 3 to the bottom wall of the heating disk 2, the heat generated by the heating disk 2 can be directly isolated by the isolating member 3 when it is conducted downward, effectively avoiding the existence of a gap between the isolating member 3 and the heating disk 2, which causes the heat of the heating disk 2 to be transferred to the air in the gap between the two, and then conducted to the stator 5 and the rotor 4 by the air. This helps to further improve the thermal insulation effect of the isolating member 3 and reduce the temperature rise of the stator 5 and the rotor 4.

[0049] Furthermore, the bottom wall of the heating plate 2 is provided with a downwardly extending fixing column, the isolating member 3 is provided with a fixing hole vertically aligned with the fixing column, and the food processor also includes a connecting member, which passes through the fixing hole and is fastened to the fixing column.

[0050] By providing the bottom wall of the heating plate 2 with a downward extending fixing column, the isolating member 3 is provided with a fixing hole vertically aligned with the fixing column, and the food processor also includes a connecting member, which passes through the fixing hole and is fastened to the fixing column, so that the isolating member 3 is connected and fixed to the heating plate 2 through the connecting member, thereby improving the stability of the connection between the isolating member 3 and the heating plate 2.

[0051] As a preferred embodiment of this embodiment, Figure 2 、 Figure 5 As shown, the heating plate 2 includes a base plate and a mounting portion provided around the base plate and protruding downward for mounting the heating tube 22 . The isolating member 3 includes a bottom surface 33 adapted to the base plate and a step surface 34 connected to the bottom surface 33 and adapted to the mounting portion.

[0052] By configuring the isolating member 3 to include a bottom surface 33 adapted to the base plate and a stepped surface 34 connected to the bottom surface 33 and adapted to the mounting portion, the isolating member 3 can achieve all-round isolation of the heating plate 2 from the stator 5 and the rotor 4. In particular, the configuration of the stepped surface 34 effectively isolates the heating tube 22 from the components below, thereby further enhancing the heat insulation effect of the isolating member 3, thereby further reducing the temperature rise of the stator 5 and the rotor 4, and improving the stability of the brushless motor.

[0053] As a preferred embodiment of the present application, Figure 2 As shown, a heat dissipation gap 8 is provided between the stator 5 , the rotor 4 and the isolating member 3 .

[0054] By providing a heat dissipation gap 8 between the stator 5 and the rotor 4 and the isolating member 3, the stator 5 and the rotor 4 are further away from the isolating member 3. Therefore, even if a large amount of heat is transferred from the heating plate 2 to the isolating member 3, the heat dissipation gap 8 can reduce the heat transfer to the stator 5 and the rotor 4, which helps to further reduce the temperature rise of the stator 5 and the rotor 4. At the same time, the heat dissipation gap 8 can also increase the air flow rate near the stator 5 and the rotor 4, thereby allowing more cold air to pass through the stator 5 and the rotor 4 per unit time and achieve heat dissipation of both, which helps to improve the heat dissipation effect of the stator 5 and the rotor 4.

[0055] It should be noted that the present application does not specifically limit the size of the heat dissipation gap 8. As a preferred embodiment of the present application, Figure 2 As shown, the vertical width L of the heat dissipation gap 8 satisfies: 3mm≤L≤20mm.

[0056] By setting the vertical width L of the heat dissipation gap 8 to satisfy: 3mm≤L≤20mm, it is avoided that the vertical width of the heat dissipation gap 8 is too small, resulting in poor insulation and heat dissipation effects, causing a high temperature rise of the stator 5 and the rotor 4 and thus causing unstable operation; at the same time, it is avoided that the vertical width of the heat dissipation gap 8 is too large, resulting in an excessively large axial dimension of the entire machine, causing it to occupy a large space and be difficult to take.

[0057] As a preferred embodiment of the present application, Figure 2 As shown, the heating plate 2 includes a heating tube 22 , and the heating tube 22 is located outside the installation cavity 6 .

[0058] By arranging the heating tube 22 outside the mounting cavity 6, the heat generated by the heating tube 22 can be isolated from the mounting cavity 6 under the obstruction of the bottom cover 7, thereby effectively reducing the heat conducted from the heating tube 22 into the mounting cavity 6, further achieving a heat insulation effect, and further reducing the temperature rise of the stator 5 and the rotor 4.

[0059] The technical solutions protected by this utility model are not limited to the above-described embodiments. It should be noted that the combination of the technical solutions of any one embodiment with the technical solutions of one or more other embodiments falls within the scope of protection of this utility model. Although the above description of this utility model has been provided in detail using general instructions and specific embodiments, it is obvious to those skilled in the art that modifications or improvements can be made based on this utility model. Therefore, such modifications or improvements made without departing from the spirit of this utility model are within the scope of protection claimed by this utility model.
