Description

Technical Field

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

[0002] Existing food processors generally include a main body and a cup assembly with a stirring member disposed therein. A series motor in the main body is drivingly connected to the stirring member. When a user uses the food processor to process food materials, the food materials are placed in the cup assembly, and the stirring member rotates at a high speed driven by the series motor to achieve crushing processing of the food materials. However, since the series motor generates relatively large noise during operation, some manufacturers will replace the series motor with a brushless motor to reduce the noise during the operation of the whole machine. When assembling the brushless motor, first fix the stator and rotor of the brushless motor between the upper cover and the lower cover, and then fix the whole brushless motor below the cup. This assembly method has cumbersome steps and low assembly efficiency. At the same time, the axial dimension of the brushless motor is relatively large, resulting in too high an axial height of the whole machine after it is installed on the cup, and further causing the center of gravity of the whole machine to become higher, resulting in the situation that the food processor shakes or even topples during food material processing. Moreover, the weight and occupied space of the whole cup assembly are relatively large, making it very laborious for the user to pick up the whole machine and very inconvenient for storage, seriously affecting the consumer experience. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a food processor with a compact structure to solve the problems that the assembly of the brushless motor in the existing food processor is relatively cumbersome and its axial dimension is relatively large, resulting in a relatively large axial dimension of the whole machine after it is installed on the cup, causing a relatively high center of gravity of the whole machine and unstable operation.

[0004] To achieve the above purpose, the utility model provides a food processor with a compact structure, which includes a cup assembly. The cup assembly includes a cup with upper and lower openings, a heating plate disposed at the lower opening of the cup, and a cup base disposed below the heating plate and connected to the cup. The heating plate is provided with a stirring knife. The food processor further includes a brushless motor disposed below the heating plate and driving the stirring knife to rotate. The brushless motor includes a stator, a rotor, and a bottom cover disposed below the stator and the rotor. The bottom cover is fixedly connected to the cup base to fix the stator and the rotor.

[0005] By using a brushless motor and leveraging its characteristics, when the user uses the food processor to process food ingredients, the noise generated by the motor rotation is lower, achieving the effect of noise reduction. At the same time, the brushless motor can achieve variable frequency control, enabling the food processor to control the brushless motor to output different speeds according to different food ingredients and processing processes, which can make the processing effect of the food ingredients better and the processing more sufficient, improving the output taste of the food ingredients. Moreover, the brushless motor occupies less space, which helps to improve the compactness of the internal structure of the whole machine and reduce the occupied space of the food processor, facilitating the user's storage.

[0006] At the same time, the stator and rotor of the brushless motor are directly fixed between the cup base and the bottom cover. Compared with the existing method that requires an additional motor upper cover, fixing the stator and rotor between the motor upper cover and the bottom cover and then fixing the whole 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 omits a motor upper cover, greatly simplifying the overall number of components of the whole motor and the whole machine, which helps to further improve the compactness of the internal structure of the whole machine and further reduce the overall weight. At the same time, it compresses the axial height between the brushless motor and the heating plate, making the axial height of the whole machine lower and thinner, further reducing the occupied space of the food processor, while reducing the center of gravity height of the whole machine, making the food processor more stable during operation, and facilitating the user to pick up the whole machine, thus improving the user experience.

[0007] In a preferred implementation of a structurally compact food processor, the cup base is provided with a downward-extending mounting post, the bottom cover is provided with a mounting hole vertically aligned with the mounting post, and the cup body assembly further includes a first connecting member that passes through the mounting hole and is fastened to the mounting post.

[0008] By providing a downward-extending mounting post on the cup base and a mounting hole vertically aligned with the mounting post on the bottom cover, when assembling the brushless motor and the cup base, only need to pass the first connecting member through the mounting hole and fasten it to the mounting post to complete the installation. The assembly steps are simple, which helps to further improve the assembly efficiency. At the same time, the connection position between the brushless motor and the cup base is relatively low, so that the vibration generated when the brushless motor rotates is transmitted to a lower position of the whole machine, thus avoiding large yaw and vibration of the whole machine and reducing the generation of vibration noise.

[0009] In a preferred implementation of a structurally compact food processor, the bottom cover includes a support seat supporting below the stator and an extension portion provided on the outer periphery of the support seat and extending outward, and the mounting hole is formed on the extension portion.

[0010] By providing a bottom cover with a support base that supports below the stator and an extension portion provided on the outer periphery of the support base and extending outward, and forming the mounting hole on the extension portion, the mounting post can be away from the support base and the stator, thus effectively avoiding the situation of noise generated by the collision between the mounting post and the stator or the support post.

[0011] In a preferred implementation of a compact food processor, the cup body assembly further includes a cup body housing that covers the outside of the brushless motor and is connected to the bottom of the cup body. The bottom cover further has a fixing post extending downward, and the cup body housing has a connecting post that is vertically aligned with the fixing post and fixedly connected thereto.

[0012] By providing a fixing post extending downward on the bottom cover, and the cup body housing having a connecting post that is vertically aligned with the fixing post and fixedly connected thereto, the bottom cover can not only be fixedly connected to the cup base through the mounting hole to realize the hoisting of the brushless motor by the cup base, but also realize the vertical support of the cup body housing for the brushless motor through the fixed connection between the fixing post and the connecting post, thereby realizing the double positioning of the brushless motor, which helps to further improve the positioning effect of the brushless motor and ensure its position stability.

[0013] In a preferred implementation of a compact food processor, the cup body assembly further includes a cup body housing that covers the outside of the brushless motor and is connected to the bottom of the cup body. The cup body assembly further includes a second connecting member that sequentially passes through the cup body housing, the bottom cover and is fastened to the cup base.

[0014] By setting the cup body assembly to further include a cup body housing that covers the outside of the brushless motor and is connected to the bottom of the cup body, the cup body assembly further includes a second connecting member, and the second connecting member sequentially passes through the cup body housing, the bottom cover and is fastened to the cup base, when assembling the cup body assembly, the fixed connection of the cup base, the brushless motor and the cup body housing can be realized through one second connecting member, the assembly steps of the whole machine are further simplified, which helps to further improve the assembly efficiency. At the same time, by connecting and fixing the three through one connecting member, the coaxiality of the whole machine can be ensured, thereby improving the rotation stability of the brushless motor and the working stability of the whole machine.

[0015] In a preferred implementation of a compact food processor, the mounting post has an abutting section that abuts above the mounting hole and an extending section with a reduced outer diameter relative to the abutting section and extending into the mounting hole, and the second connecting member passes through the support post and is fastened to the extending section.

[0016] By setting the installation post to have an abutting section that abuts above the installation hole and an extension section whose outer diameter is reduced relative to the abutting section and extends into the installation hole, the second connecting piece passes through the support post and is fastened to the extension section. After the extension section extends into the installation hole, the extension section and the installation hole achieve radial abutment, thereby realizing their radial positioning. At the same time, after the second connecting piece is fastened to the extension section, the direct cooperation between the support post and the installation post is realized, which can further improve the stability of the connection and cooperation among the three and improve their coaxiality.

[0017] In a preferred implementation of a structurally compact food processor, the bottom cover includes a support seat that supports the stator below. The support seat includes a bottom plate and a surrounding plate that extends upward from the bottom plate. The surrounding plate is provided with a support portion for supporting the stator.

[0018] By setting the support seat to include a bottom plate and a surrounding plate that extends upward from the bottom plate, and the surrounding plate is provided with a support portion for supporting the stator, the base can not only support the stator and the rotor, but also limit the stator through the support portion of the surrounding plate, improving the stability of the stator position, and further improving the stability of the brushless motor operation.

[0019] In a preferred implementation of a structurally compact food processor, there is a heat dissipation gap between the top end of the surrounding plate and the cup base.

[0020] By providing a heat dissipation gap between the top end of the surrounding plate and the cup base, the brushless motor can achieve effective heat dissipation through the heat dissipation gap during operation, reducing the temperature rise of the brushless motor, avoiding the situation where the brushless motor ages severely due to high temperature, helping to improve the service life of the brushless motor, and at the same time avoiding the situation where the surrounding plate directly contacts the cup base and causes noise when the brushless motor operates, improving the user experience.

[0021] In a preferred implementation of a structurally compact food processor, the brushless motor further includes a bearing provided below the rotor, and the bottom plate is provided with a limiting rib that extends upward and surrounds the outside of the bearing.

[0022] By providing a limiting rib on the bottom plate that extends upward and surrounds the outside of the bearing, radial limitation of the bearing is achieved, improving the position reliability of the bearing, and further ensuring the stability when the brushless motor rotates.

Detailed implementation manners

[0032] For a clearer explanation of the overall concept of the present utility model, the following will be further described in detail by way of examples in combination with the accompanying drawings of the specification.

[0033] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present utility model is not limited by the specific implementation manners disclosed below.

[0034] As Figures 1 to 6 shown, the present utility model provides a food processor with a compact structure, including a cup body assembly. The cup body assembly includes a cup body 1 with openings at both the top and bottom, a heating plate 2 provided at the lower opening of the cup body 1, and a cup base 3 provided below the heating plate 2 and connected to the cup body 1. The heating plate 2 is provided with a stirring blade 4. The food processor further includes a brushless motor provided below the heating plate 2 and driving the stirring blade 4 to rotate. The brushless motor includes a stator 5, a rotor 6, and a bottom cover 7 provided below the stator 5 and the rotor 6. The bottom cover 7 is fixedly connected to the cup base 3 to fix the stator 5 and the rotor 6.

[0035] In this application, by using a brushless motor and leveraging its characteristics, when a user uses a food processor to process ingredients, the motor rotates with lower noise, achieving the effect of noise reduction. At the same time, the brushless motor can achieve variable frequency control, enabling the food processor to control the brushless motor to output different speeds according to different ingredients and processing processes, which can make the processing effect of the ingredients better and the processing more sufficient, improving the taste of the processed ingredients. Moreover, the brushless motor occupies less space, which helps to improve the compactness of the internal structure of the whole machine, reduce the occupied space of the food processor, and facilitate the user's storage.

[0036] At the same time, the stator 5 and rotor 6 of the brushless motor are directly fixed between the cup base 3 and the bottom cover 7. Compared with the existing situation where an additional motor upper cover is required, and the stator 5 and rotor 6 are fixed between the motor upper cover and the bottom cover 7 and then the whole brushless motor is fixed on the heating plate 2, in this solution, the assembly of the brushless motor is also realized when assembling the whole machine, simplifying the installation steps. At the same time, an additional motor upper cover is omitted, greatly simplifying the overall number of components of the whole motor and the whole machine, which helps to further improve the compactness of the internal structure of the whole machine and further reduce the overall weight. At the same time, the axial height between the brushless motor and the heating plate 2 is compressed, so that the axial height of the whole machine is lower and thinner, further reducing the occupied space of the food processor. At the same time, the center of gravity height of the whole machine is reduced, making the food processor more stable during operation, and at the same time facilitating the user to pick up the whole machine, improving the user experience.

[0037] It should be noted that the structure of the cup base 3 is not specifically limited in this application. As a preferred embodiment of this application, as Figure 1 and Figure 4 shown, the cup base 3 is of an annular structure, and there is an avoidance opening in the middle for the top of the brushless motor to protrude upward; the cup base 3 can also be a complete plate-like structure, and at this time the top of the brushless motor can be adjacent to or abut against the cup base 3. In both of the above two solutions, the brushless motor is arranged below the heating plate 2, which will not be elaborated here.

[0038] At the same time, it should be noted that the fixation of the brushless motor is not specifically limited in this application, and it can be any one of the following embodiments:

The first connecting member 9 passes through the mounting hole 73 and is fastened to the mounting post 31.

[0040] By providing a mounting post 31 extending downward on the cup base 3 and the bottom cover 7 being provided with a mounting hole 73 vertically aligned with the mounting post 31, when assembling the brushless motor and the cup base 3, it only needs to pass the first connecting member 9 through the mounting hole 73 and fasten it to the mounting post 31 to complete the installation. The assembly steps are simple, which helps to further improve the assembly efficiency. At the same time, the connection position between the brushless motor and the cup base 3 is relatively low, so that the vibration generated when the brushless motor rotates is transmitted to a lower position of the whole machine, thereby avoiding large yaw and vibration of the whole machine and reducing the generation of vibration noise.

[0041] Further, as Figure 3 shown, the bottom cover 7 includes a support seat supporting below the stator 5 and an extension portion 74 provided on the outer periphery of the support seat and extending outward, and the mounting hole 73 is formed on the extension portion 74.

[0042] By providing the bottom cover 7 with a support seat supporting below the stator 5 and an extension portion 74 provided on the outer periphery of the support seat and extending outward, and the mounting hole 73 being formed on the extension portion 74, the mounting post 31 can be far away from the support seat and the stator 5, thus effectively avoiding the situation of generating noise due to the collision between the mounting post 31 and the stator 5 or the support column.

[0043] It should be noted that the structure of the extension portion 74 is not specifically limited in this application. As a preferred embodiment of this application, as Figure 3 shown, the extension portion 74 is a plurality of cantilevers provided on the outer periphery of the support seat and extending outward; it can also be an annular disc provided on the outer periphery of the support seat and extending outward, which will not be elaborated here.

[0044] As a preferred embodiment under this example, the cup body assembly further includes a cup body 1 outer shell covering the outside of the brushless motor and connected to the bottom of the cup body 1. The bottom cover 7 is further provided with a fixing post extending downward, and the cup body 1 outer shell is provided with a connecting post vertically aligned with the fixing post and fixedly connected thereto.

[0045] By providing the bottom cover 7 with a fixing post extending downward, and the cup body 1 outer shell being provided with a connecting post vertically aligned with the fixing post and fixedly connected thereto, the bottom cover 7 can not only be fixedly connected to the cup base 3 through the mounting hole 73 to realize the hoisting of the brushless motor by the cup base 3, but also realize the vertical support of the cup body 1 outer shell for the brushless motor through the fixed connection between the fixing post and the connecting post, thereby realizing the double positioning of the brushless motor, which helps to further improve the positioning effect on the brushless motor and ensure its position stability.

[0046] Embodiment 2: As Figure 5 、 Figure 6As shown, in this embodiment, the cup body assembly further includes a cup body 1 housing that covers the outside of the brushless motor and is connected to the bottom of the cup body 1. The cup body assembly further includes a second connecting member 10. The second connecting member 10 sequentially passes through the cup body 1 housing and the bottom cover 7 and is fastened to the cup base 3.

[0047] By setting the cup body assembly to further include a cup body 1 housing that covers the outside of the brushless motor and is connected to the bottom of the cup body 1, the cup body assembly further includes a second connecting member 10, and the second connecting member 10 sequentially passes through the cup body 1 housing, the bottom cover 7 and is fastened to the cup base 3. When assembling the cup body assembly, the fixed connection of the cup base 3, the brushless motor and the cup body 1 housing can be realized through one second connecting member 10, which further simplifies the assembly steps of the whole machine and helps to further improve the assembly efficiency. At the same time, by connecting and fixing the three through one connecting member, the coaxiality of the whole machine can be ensured, thereby improving the stability of the rotation of the brushless motor and the stability of the operation of the whole machine.

[0048] As a preference under this embodiment, as Figure 6 shown, the cup base 3 is provided with a mounting post 31 extending downward. The bottom cover 7 is provided with a mounting hole 73 vertically aligned with the mounting post 31. The cup body 1 housing is provided with a support post extending upward and vertically aligned with the mounting hole 73. The second connecting member 10 sequentially passes through the support post, the mounting hole 73 and is fastened to the mounting post 31.

[0049] Furthermore, as Figure 6 shown, the mounting post 31 has an abutting section 311 that abuts above the mounting hole 73 and an extending section 312 with an outer diameter smaller than that of the abutting section 311 and extending into the mounting hole 73. The second connecting member 10 passes through the support post and is fastened to the extending section 312.

[0050] By setting the mounting post 31 to have an abutting section 311 that abuts above the mounting hole 73 and an extending section 312 with an outer diameter smaller than that of the abutting section 311 and extending into the mounting hole 73, and the second connecting member 10 passes through the support post and is fastened to the extending section 312, after the extending section 312 extends into the mounting hole 73, the extending section 312 and the mounting hole 73 achieve radial abutment, thereby realizing their radial positioning. At the same time, after the second connecting member 10 is fastened to the extending section 312, the direct cooperation between the support post and the mounting post 31 is realized, which can further improve the stability of the connection and cooperation of the three and improve their coaxiality.

[0051] As a preferred embodiment of the present application, as Figure 1 shown, the bottom cover 7 includes a support seat that supports the stator 5 below. The support seat includes a bottom plate 71 and a surrounding plate 72 extending upward from the bottom plate 71. The surrounding plate 72 is provided with a support portion for supporting the stator 5.

[0052] By setting the support base to include a bottom plate 71 and a surrounding plate 72 extending upward from the bottom plate 71, and the surrounding plate 72 is provided with a support portion for supporting the stator 5, the base can not only support the stator 5 and the rotor 6, but also limit the stator 5 through the support portion of the surrounding plate 72, improving the stability of the position of the stator 5, and further improving the stability of the operation of the brushless motor. Specifically, as Figure 1 shown, the support portion is a step with the stepped surface facing upward formed at the top end of the surrounding plate 72, and the stepped surface abuts against the bottom end of the stator 5, and the inner side wall of the step abuts against the side wall of the stator 5.

[0053] As a preference under this embodiment, as Figure 1 shown, there is a heat dissipation gap between the top end of the surrounding plate 72 and the cup base 3.

[0054] By providing a heat dissipation gap between the top end of the surrounding plate 72 and the cup base 3, the brushless motor can effectively dissipate heat through the heat dissipation gap during operation, reducing the temperature rise of the brushless motor, avoiding the situation that the brushless motor ages severely due to high temperature, helping to improve the service life of the brushless motor, and at the same time avoiding the situation that the surrounding plate 72 directly contacts the cup base 3 and generates noise when the brushless motor operates, improving the user experience.

[0055] Furthermore, as Figure 1 shown, the brushless motor further includes a bearing provided below the rotor 6, and the bottom plate 71 is provided with a limiting rib 711 extending upward and surrounding the outside of the bearing.

[0056] By providing a limiting rib 711 on the bottom plate 71 that extends upward and surrounds the outside of the bearing, radial limitation of the bearing is achieved, improving the position reliability of the bearing, and further ensuring the stability when the brushless motor rotates.
