Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and more particularly, to a food processor and a motor. Background Art

[0002] Currently, food processors in related technologies are limited by the sizes of components such as motors and heating plates, resulting in a rather bulky appearance of the food processors. When used by users, they are often difficult to store, difficult to carry, and the cup body is also relatively difficult to lift and place. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0004] To this end, in a first aspect of the present invention, a food processor is provided.

[0005] In a second aspect of the present invention, a motor is provided.

[0006] In view of this, the present invention provides a food processor, including: a base assembly; a cup body assembly capable of being installed on the base assembly, the cup body assembly including a cutter assembly; a motor, the motor including a stator assembly and a rotor assembly, the stator assembly being disposed within the base assembly, the rotor assembly driving the cutter assembly to rotate, the stator assembly being capable of driving the rotor assembly to rotate, wherein the magnetic field lines between the stator assembly and the rotor assembly point from the N pole of the stator assembly to the S pole of the rotor assembly along the rotation axis direction of the rotor assembly, and from the N pole of the rotor assembly to the S pole of the stator assembly; the magnetic field lines inside the stator assembly point from the S pole of the stator assembly to the N pole of the stator assembly along the circumferential direction of the stator assembly, and the magnetic field lines inside the rotor assembly point from the S pole of the rotor assembly to the N pole of the rotor assembly along the circumferential direction of the rotor assembly.

[0007] The food processor provided by the present invention includes a base assembly, a cup body assembly and a motor. The cup body assembly can be installed on the base assembly. The motor includes a stator assembly and a rotor assembly. The stator assembly is arranged inside the base assembly. The stator assembly can drive the rotor assembly to rotate, and the rotor assembly can drive the tool assembly to rotate, thereby realizing the processing of food materials. Among them, the magnetic lines of force inside the stator assembly point from the S pole of the stator assembly to the N pole of the stator assembly along the circumferential direction of the stator assembly, so that the magnetic field of the stator assembly rotates along the circumferential direction. The N pole of the stator assembly generates a repulsive force on the N pole of the rotor assembly, the S pole of the stator assembly generates an attractive force on the N pole of the rotor assembly, the S pole of the stator assembly generates a repulsive force on the N pole of the rotor assembly, and the N pole of the stator assembly generates an attractive force on the S pole of the rotor assembly. The electromagnetic forces acting on the N pole and S pole of the rotor assembly in the axial direction of the rotor assembly cancel each other out, and the resultant force direction is the electromagnetic force in the circumferential direction. Therefore, when the magnetic field of the stator assembly rotates along the circumferential direction, the rotor assembly will also rotate in the same direction. Furthermore, under the action of the stator assembly, the rotation of the rotor assembly is realized. Through the rotation of the rotor assembly, the rotation of the tool assembly is realized, and thus the processing of food is realized. In addition, through the magnetic field distribution of the stator assembly and the rotor assembly, the axial magnetic flux of the motor is realized, and thus the stator assembly and the rotor assembly can be arranged separately along the axial direction. When the user stores the food processor, the part with the stator assembly and the part with the rotor assembly can be stored separately, which improves the convenience of storage and carrying.

[0008] It can be understood that the stator assembly has coils, and the magnetic field generated by passing three-phase alternating current through the coils rotates along the circumferential direction.

[0009] Optionally, when the magnetic field of the stator assembly rotates along the circumferential direction, the rotor assembly will also rotate in the same direction and at the same speed.

[0010] According to the food processor provided by the present invention, the following additional technical features may also be included:

[0011] In some possible designs, the rotor assembly is arranged inside the cup body assembly, and along the axial direction of the rotation axis of the rotor assembly, the rotor assembly is located on one side of the stator assembly.

[0012] In this design, the stator assembly is disposed within the base assembly, and the rotor assembly is disposed within the cup assembly. The rotor assembly is connected to the tool assembly. Under the interaction of the magnetic fields of the stator assembly and the rotor assembly, the rotor assembly can rotate, thereby driving the tool assembly to rotate to achieve the processing of the food ingredients within the cup assembly. Among them, the rotor assembly is disposed on one side of the stator assembly in the axial direction. Through the axial flux coupling principle, the separation of the rotor assembly and the stator assembly is achieved. At the same time, it is also possible to reduce the axial thickness of the motor and the weight of the motor, which is conducive to reducing the overall height and weight of the food processor and facilitating the storage and transportation of the food processor. In addition, by separately disposing the stator assembly and the rotor assembly, there is no need to provide a connecting shaft to pass through the cup assembly to achieve power transmission, improving the sealing performance of the cup assembly and reducing the noise during the operation of the food processor.

[0013] In some possible designs, along the axis direction of the rotation of the rotor assembly, the gap between the rotor assembly and the stator assembly is greater than 0 mm and less than or equal to 5 mm.

[0014] In this design, if the axial gap between the rotor assembly and the stator assembly is too large, it will affect the transmission of the magnetic flux linkage and torque between the two, reducing the efficiency of the motor. If it is compensated by increasing the number of turns of the inductor and increasing the magnetic flux, it will lead to too high costs. Therefore, along the axis direction of the rotation of the rotor assembly, the gap between the rotor assembly and the stator assembly is set to be less than or equal to 5 mm, ensuring the performance of the motor such as inductance, resistance, starting torque, and magnetic flux linkage.

[0015] In some possible designs, the rotor assembly includes: a first magnetic conductive cover fixedly connected to the tool assembly; a second magnetic conductive cover connected to the first magnetic conductive cover and enclosing an installation cavity with the first magnetic conductive cover; a first magnetic member disposed within the installation cavity. The N pole of the rotor assembly includes the N pole of the first magnetic member, and the S pole of the rotor assembly includes the S pole of the first magnetic member.

[0016] In this design, the rotor assembly includes a first magnetic conductive cover, a second magnetic conductive cover, and a first magnetic member. The first magnetic conductive cover and the second magnetic conductive cover are connected and enclose an installation cavity. The first magnetic member is disposed within the installation cavity, achieving the limiting and installation of the first magnetic member. At the same time, the settings of the first magnetic conductive cover and the second magnetic conductive cover also ensure the magnetic flux effect, thereby ensuring the driving performance of the motor. The N pole of the rotor assembly includes the N pole of the first magnetic member, and the S pole of the rotor assembly includes the S pole of the first magnetic member. The N pole of the stator assembly points to the S pole of the first magnetic member along the axis direction of the rotation of the rotor assembly, and the N pole of the first magnetic member points to the S pole of the stator assembly along the axis direction of the rotation of the rotor assembly, causing the first magnetic member to rotate around the axis of rotation of the rotor assembly.

[0017] Specifically, the N pole of the rotor assembly is the N pole of the first magnetic member, and the S pole of the rotor assembly is the S pole of the first magnetic member. The magnetic lines of force inside the first magnetic member point from the S pole to the N pole of the first magnetic member along the circumferential direction of the first magnetic member. The N pole of the stator assembly points to the S pole of the first magnetic member along the rotation axis direction of the rotor assembly, and the N pole of the first magnetic member points to the S pole of the stator assembly along the rotation axis direction of the rotor assembly.

[0018] In some possible designs, the first magnetic member is in a disc shape or the first magnetic member is in an annular shape.

The isolation cover is arranged on the top of the first seat body, and the cup body assembly can be placed on the isolation cover, realizing the separation between the stator assembly and the rotor assembly, reducing or eliminating the eddy current phenomenon between the two, and further improving the magnetic field coupling performance between the stator assembly and the rotor assembly.

[0022] In some possible designs, the isolation cover includes a non-metallic member; and / or along the rotation axis direction of the rotor assembly, the thickness of the isolation cover is less than or equal to 5 mm.

[0023] In this design, the isolation cover includes a non-metallic member. Setting a non-metallic member between the rotor assembly and the stator assembly can reduce or eliminate the eddy current phenomenon between the two, and further improve the magnetic field coupling performance between the stator assembly and the rotor assembly. Among them, if the thickness of the isolation cover is too large, it will affect the transmission of magnetic flux linkage and torque between the stator assembly and the rotor assembly, reducing the efficiency of the motor. Therefore, the thickness of the isolation cover is set to be less than or equal to 5 mm to ensure the reliability of torque transmission between the stator assembly and the rotor assembly while reducing or eliminating eddy currents.

[0024] Optionally, the surface of the isolation cover in contact with the cup body assembly is a smooth and continuous plane or curved surface or arc surface, which is easy to clean.

[0025] Optionally, when the cup body assembly is placed on the isolation cover, it can be placed in any direction of 360° circumferentially, without the user spending time to accurately find the alignment position, which is very convenient to use.

[0026] Optionally, an opening is provided on the first base body, and the isolation cover is arranged at the opening. Specifically, along the axial direction of the rotor assembly, the surface of the isolation cover facing the cup assembly is lower than the surface of the first base body facing the cup assembly, so that the isolation cover is lower than the first base body, and thus a groove can be formed at the opening, facilitating the cooperation between the cup assembly and the base assembly.

[0027] Of course, the first base body may not be provided with an opening, that is, the top of the first base body is directly a flat surface. For example, the isolation cover and the first base body may be integrally formed, and the first base body does not need to be provided with an opening. Or the first base body is directly integrally formed into a flat surface, and the isolation cover is arranged on the flat surface.

[0029] In this design, the base assembly further includes a shock absorber. The shock absorber is arranged between the stator assembly and the first base body, and at the bottom of the first base body, which can reduce the vibration generated when the stator assembly works, and thus reduce the noise when the food processor works.

[0031] In this design, the cup assembly further includes a cup body, a second base body and a seal. The second base body and the cup body enclose a cavity. The cutter assembly is arranged in the cavity and divides the cavity into a first cavity and a second cavity. The first cavity is used to hold food ingredients. A part of the cutter assembly extends into the first cavity, and the other part is located in the second cavity and is connected to the rotor assembly in the second cavity. The rotor assembly drives the cutter assembly to rotate, driving the part of the cutter assembly located in the first cavity to rotate, so as to realize the processing of the food ingredients in the first cavity. Among them, a seal is arranged at the connection between the second base body and the cup body, realizing the sealing of the second cavity, and thus enabling the whole cup assembly to be washed with water, improving the convenience of cleaning.

[0032] In some possible designs, the cutter assembly includes: a rotating shaft, a part of the rotating shaft is located in the first cavity, and a part of the rotating shaft is arranged in the second cavity.

[0033] In this design, the cutter assembly includes a rotating shaft and a cutter. A part of the rotating shaft is located inside the first cavity for installing the cutter, and a part of the rotating shaft is located inside the second cavity for connecting to the rotor assembly, so as to realize the processing of food materials by the cutter through the rotation of the rotor assembly.

The rotating shaft is arranged on the chassis, and further transmits the driving force of the rotor assembly in the second cavity to the cutter in the first cavity.

[0042] In some possible designs, the food processor further includes: a first magnetic conductive member, which is arranged on the cup body assembly; a second magnetic member, which is arranged on the rotor assembly or the cutter assembly. When the stator assembly is energized to generate a magnetic field, the rotor assembly can drive the second magnetic member to rotate so that the first magnetic conductive member heats the cup body assembly.

[0043] In this design, the food processor further includes a first magnetic conductive member and a second magnetic member. The first magnetic conductive member is disposed on the cup body assembly, and the second magnetic member is disposed on the rotor assembly or the tool assembly. Under the interaction of the magnetic field of the stator assembly and the magnetic field of the rotor assembly, the rotor assembly is driven to rotate, and then the tool assembly and the second magnetic member are driven to rotate. The rotation of the tool assembly can realize the processing of the food materials in the cup body assembly; the rotation of the second magnetic member can generate a rotating magnetic field, and then the first magnetic conductive member cuts the magnetic induction lines to generate heat, realizing the heating of the food materials in the cup body assembly.

[0061] In some possible designs, the stator core is disc-shaped or the stator core is annular.

[0062] In this design, the stator core is disc-shaped, which can achieve high magnetic flux and high torque, thereby improving the driving effect on the tool assembly. The stator core can also be annular, and the hollow part can increase the heat dissipation effect and slow down the aging speed of the motor.

[0063] According to the second aspect of the present application, a motor is further proposed, including: a stator assembly; a rotor assembly, and the stator assembly can drive the rotor assembly to rotate. Among them, the magnetic lines of force between the stator assembly and the rotor assembly point from the N pole of the stator assembly to the S pole of the rotor assembly and from the N pole of the rotor assembly to the S pole of the stator assembly along the rotation axis direction of the rotor assembly; the magnetic lines of force inside the stator assembly point from the S pole of the stator assembly to the N pole of the stator assembly along the circumferential direction of the stator assembly, and the magnetic lines of force inside the rotor assembly point from the S pole of the rotor assembly to the N pole of the rotor assembly along the circumferential direction of the rotor assembly.

[0064] According to the motor proposed in this application, the magnetic field lines inside the stator assembly point from the S pole to the N pole of the stator assembly along the circumferential direction of the stator assembly, causing the magnetic field of the stator assembly to rotate circumferentially. The N pole of the stator assembly generates a repulsive force on the N pole of the rotor assembly, the S pole of the stator assembly generates an attractive force on the N pole of the rotor assembly, the S pole of the stator assembly generates a repulsive force on the N pole of the rotor assembly, and the N pole of the stator assembly generates an attractive force on the S pole of the rotor assembly. The electromagnetic forces acting on the N and S poles of the rotor assembly in the axial direction of the rotor assembly cancel each other out, and the resultant force direction is the electromagnetic force in the circumferential direction. Therefore, when the magnetic field of the stator assembly rotates circumferentially, the rotor assembly will also rotate in the same direction. Thus, under the action of the stator assembly, the rotation of the rotor assembly is realized, and through the rotation of the rotor assembly, the output of the driving force is achieved. In addition, through the magnetic field distribution of the stator assembly and the rotor assembly, the axial magnetic flux of the motor is realized, and thus the stator assembly and the rotor assembly can be axially separated. When the user stores it, the part with the stator assembly and the part with the rotor assembly can be stored separately, improving the convenience of storage and carrying.

[0065] It can be understood that the stator assembly has coils, and the magnetic field generated by the coils when passing through three-phase alternating current rotates circumferentially.

[0066] Optionally, when the magnetic field of the stator assembly rotates circumferentially, the rotor assembly will also rotate in the same direction and at the same speed.

[0067] In some possible designs, along the axis direction of the rotation of the rotor assembly, the rotor assembly is located on one side of the stator assembly.

[0068] In this design, the rotor assembly is arranged on one side of the stator assembly axially. Through the principle of axial magnetic flux coupling, while ensuring the driving connection between the stator assembly and the rotor assembly, the separation of the rotor assembly and the stator assembly is realized. At the same time, it can also reduce the axial thickness and weight of the motor, which is beneficial to the storage and transportation of the motor.

[0069] In some possible designs, along the axis direction of the rotation of the rotor assembly, the gap between the rotor assembly and the stator assembly is greater than 0 mm and less than or equal to 5 mm.

[0070] In this design, if the axial gap between the rotor assembly and the stator assembly is too large, it will affect the transmission of the magnetic flux linkage and torque between the two, reducing the efficiency of the motor. If it is compensated by increasing the number of turns of the inductor and increasing the magnetic flux, the cost will be too high. Therefore, along the axis direction of the rotation of the rotor assembly, the gap between the rotor assembly and the stator assembly is set to be less than or equal to 5 mm, ensuring the performance of the motor such as inductance, resistance, starting torque, and magnetic flux linkage.

[0071] In some possible designs, the rotor assembly includes: a first magnetic conductive cover; a second magnetic conductive cover connected to the first magnetic conductive cover and enclosing an installation cavity with the first magnetic conductive cover; and a first magnetic member disposed in the installation cavity, where the N pole of the rotor assembly includes the N pole of the first magnetic member, and the S pole of the rotor assembly includes the S pole of the first magnetic member.

[0072] In this design, the rotor assembly includes a first magnetic conductive cover, a second magnetic conductive cover, and a first magnetic member. The first magnetic conductive cover and the second magnetic conductive cover are connected and enclose an installation cavity, and the first magnetic member is disposed in the installation cavity, achieving the limitation and installation of the first magnetic member. At the same time, the setting of the first magnetic conductive cover and the second magnetic conductive cover also ensures the magnetic flux effect, thereby ensuring the driving performance of the motor. The N pole of the rotor assembly includes the N pole of the first magnetic member, and the S pole of the rotor assembly includes the S pole of the first magnetic member. The N pole of the stator assembly points to the S pole of the first magnetic member along the rotation axis direction of the rotor assembly, and the N pole of the first magnetic member points to the S pole of the stator assembly along the rotation axis direction of the rotor assembly, causing the first magnetic member to rotate around the rotation axis of the rotor assembly.

[0073] Specifically, the N pole of the rotor assembly is the N pole of the first magnetic member, and the S pole of the rotor assembly is the S pole of the first magnetic member. The magnetic lines of force inside the first magnetic member point from the S pole to the N pole of the first magnetic member along the circumferential direction of the first magnetic member. The N pole of the stator assembly points to the S pole of the first magnetic member along the rotation axis direction of the rotor assembly, and the N pole of the first magnetic member points to the S pole of the stator assembly along the rotation axis direction of the rotor assembly.

[0074] In some possible designs, the first magnetic member is in a disc shape or the first magnetic member is in an annular shape.

[0075] In this design, the first magnetic member can be in a disc shape, which can improve the magnetic flux and torque of the motor; the first magnetic member can also be in an annular shape, which can conduct heat through the hollow part to ensure a lower temperature rise of the motor, slow down the aging speed of the motor materials, and improve the operation stability and lifespan of the motor.

[0076] In some possible designs, the stator assembly includes: a stator core, where the stator core includes multiple laminations, the multiple laminations enclose a central through-hole, and the multiple laminations are stacked in the radial direction of the central through-hole.

[0077] In this design, the stator core includes multiple laminations, the multiple laminations enclose a central through-hole, and the multiple laminations are stacked in the radial direction of the central through-hole, thereby effectively reducing the magnetic resistance of the stator core, reducing magnetic loss, improving the motor efficiency, making the magnetic circuit of the stator core shorter, the motor can be made more flat and thinner, and the miniaturization of the motor can be achieved.

[0078] In some possible designs, the multiple laminations are formed by rolling up a single lamination from the inside out along a spiral line.

[0079] In this design, during the process of machining and manufacturing the stator core, the final stator core can be obtained through the convolution of a single punching sheet, and the manufacturing process is simple, which can reduce the cost of the stator core.

[0080] In some possible designs, the stator assembly further includes: a third base; a bracket disposed within the third base, the bracket including a base and a winding portion provided on the base, an avoidance notch being provided on the base, and the winding portion extending in a direction away from the base along the avoidance notch; a coil wound around the winding portion, the N pole of the stator assembly including the N pole of the coil, and the S pole of the stator assembly including the S pole of the coil. Wherein, a plurality of winding grooves are provided on at least one end face of the stator core, the winding grooves penetrate from the outer surface of the stator core towards the inside of the stator core, and the plurality of winding grooves are distributed along the circumferential direction of the stator core. Two adjacent winding grooves define a stator tooth, and the stator tooth passes through the base from the avoidance notch, and the stator tooth and the coil are arranged in isolation through the winding portion.

[0081] In this design, the stator assembly further includes a third base, a bracket, and a coil. The N pole of the stator assembly includes the N pole of the coil, and the S pole of the stator assembly includes the S pole of the coil. When the coil is energized, the N pole of the coil points towards the S pole of the rotor assembly along the rotation axis direction of the rotor assembly, and the N pole of the rotor assembly points towards the S pole of the coil along the rotation axis direction of the rotor assembly, causing the rotor assembly to rotate around the rotation axis. The bracket is disposed within the third base, the bracket includes a base and a winding portion provided on the base, and the stator tooth of the stator core passes through the base from the avoidance notch on the base, so that the winding portion is sleeved on the stator tooth, and the coil is wound around the stator tooth through the winding portion.

[0082] Specifically, the N pole of the stator assembly is the N pole of the coil, and the S pole of the stator assembly is the S pole of the coil. When the coil is energized, along the circumferential direction of the coil, the magnetic lines of force inside the coil point from the S pole of the coil to the N pole of the coil; the N pole of the coil points towards the S pole of the first magnetic member along the rotation axis direction of the rotor assembly, and the N pole of the first magnetic member points towards the S pole of the coil along the rotation axis direction of the rotor assembly.

[0083] In some possible designs, a flanging structure is provided at one end of the winding portion away from the base, and the winding portion is located between the flanging structure and the base.

[0084] In this design, a flanging structure is provided at one end of the winding portion away from the base, and the flanging structure, the base, and the winding portion jointly construct a limiting space. The coil is disposed within the limiting space and is wound around the winding portion, which can ensure the stable installation of the coil and prevent the coil from falling off.

[0085] In some possible designs, the side wall of the third body is provided with a plurality of heat dissipation holes.

[0086] In this design, a plurality of heat dissipation holes are provided on the side wall of the third body, which can improve the heat dissipation efficiency of the stator assembly in the third body, thereby improving the heat dissipation effect of the motor, slowing down the aging speed of the motor, and increasing the service life of the motor.

[0087] In some possible designs, the stator core is in a disc shape or the stator core is in an annular shape.

Detailed implementation manners

[0104] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0105] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0106] Next, refer to Figures 1 to 10 Describe the food processor 100 and the motor 4 according to some embodiments of the present invention.

[0107] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 9 and Figure 10 shown, according to an embodiment of the present invention, the present invention provides a food processor 100, including: a base assembly 1, a cup body assembly 2 and a motor 4.

[0108] Specifically, the cup body assembly 2 can be installed on the base assembly 1. The cup body assembly 2 includes a cutter assembly. The motor 4 includes a stator assembly 40 and a rotor assembly 42. The stator assembly 40 is disposed inside the base assembly 1. The rotor assembly 42 drives the cutter assembly to rotate. The stator assembly 40 can drive the rotor assembly 42 to rotate. Among them, the magnetic lines of force between the stator assembly 40 and the rotor assembly 42 point from the N pole of the stator assembly 40 to the S pole of the rotor assembly 42 along the rotation axis direction of the rotor assembly 42, and from the N pole of the rotor assembly 42 to the S pole of the stator assembly 40. The magnetic lines of force inside the stator assembly 40 point from the S pole of the stator assembly 40 to the N pole of the stator assembly 40 along the circumferential direction of the stator assembly 40, and the magnetic lines of force inside the rotor assembly 42 point from the S pole of the rotor assembly 42 to the N pole of the rotor assembly 42 along the circumferential direction of the rotor assembly 42.

[0109] The food processor 100 provided by the present invention includes a base assembly 1, a cup body assembly 2 and a motor 4. The cup body assembly 2 can be installed on the base assembly 1. The motor 4 includes a stator assembly 40 and a rotor assembly 42. The stator assembly 40 is disposed inside the base assembly 1. The stator assembly 40 can drive the rotor assembly 42 to rotate. The rotor assembly 42 can drive the cutter assembly 3 to rotate, thereby realizing the processing of food materials. Among them, the rotor assembly 42 drives the cutter assembly to rotate, thereby realizing the processing of food materials. Among them, the magnetic lines of force inside the stator assembly 40 point from the S pole of the stator assembly 40 to the N pole of the stator assembly 40 along the circumferential direction of the stator assembly 40, so that the magnetic field of the stator assembly 40 rotates circumferentially. The N pole of the stator assembly 40 generates a repulsive force on the N pole of the rotor assembly 42, the S pole of the stator assembly 40 generates an attractive force on the N pole of the rotor assembly 42, the S pole of the stator assembly 40 generates a repulsive force on the N pole of the rotor assembly 42, the N pole of the stator assembly 40 generates an attractive force on the S pole of the rotor assembly 42. The electromagnetic forces acting on the N pole and S pole of the rotor assembly 42 in the axial direction of the rotor assembly 42 cancel each other out, and the resultant force direction is the electromagnetic force in the circumferential direction. Therefore, when the magnetic field of the stator assembly 40 rotates circumferentially, the rotor assembly 42 will also rotate in the same direction. Thus, under the action of the stator assembly 40, the rotation of the rotor assembly 42 is realized. Through the rotation of the rotor assembly 42, the rotation of the cutter assembly is realized, thereby realizing the processing of food. In addition, through the magnetic field distribution of the stator assembly 40 and the rotor assembly 42, the axial magnetic flux of the motor 4 is realized, and thus the stator assembly 40 and the rotor assembly 42 can be axially separated. When the user stores it, the part with the stator assembly 40 and the part with the rotor assembly 42 can be stored separately, improving the convenience of storage and carrying.

[0110] It can be understood that the stator assembly 40 has a coil, and the magnetic field generated by passing three-phase alternating current through the coil rotates circumferentially.

[0111] Optionally, when the magnetic field of the stator assembly 40 rotates circumferentially, the rotor assembly 42 also rotates in the same direction and at the same speed.

[0112] It can be understood that the stator assembly 40 has a plurality of N poles (such as N pole ① and N pole ②) and a plurality of S poles. Specifically, as Figure 9 and Figure 10 shown, the N pole ① of the stator assembly 40 generates an attractive force with the N pole of the rotor assembly 42. The S poles of the stator assembly 40 generate attractive and repulsive forces on the N pole and S pole of the rotor assembly 42 respectively. The N pole ② of the stator assembly 40 generates an attractive force on the S pole of the rotor assembly 42. The electromagnetic forces in the axial direction on the N pole and S pole of the rotor assembly 42 cancel each other out, and the resultant force is only the electromagnetic force in the circumferential direction. Therefore, when the magnetic field of the stator assembly 40 rotates circumferentially, the rotor assembly 42 also rotates in the same direction and at the same rotational speed.

[0113] Optionally, the stator assembly 40 includes a coil 406, and the rotor assembly 42 includes a permanent magnet. The magnetic flux direction of the permanent magnet is axial. The magnetic field of the coil 406 interacts with the magnetic field of the permanent magnet to generate a torque, thereby driving the rotor to rotate.

[0114] Optionally, the stator assembly 40 and the rotor assembly 42 are in a disc shape.

[0115] Optionally, the cup body assembly 2 is detachably connected to the base assembly 1.

[0116] Optionally, the motor 4 includes an axial flux motor.

[0117] According to an embodiment of the present application, optionally, the rotor assembly 42 is disposed inside the cup body assembly 2. Along the axial direction of the rotation axis of the rotor assembly 42, the rotor assembly 42 is located on one side of the stator assembly 40.

[0118] In this embodiment, the stator assembly 40 is disposed inside the base assembly 1, and the rotor assembly 42 is disposed inside the cup body assembly 2. The rotor assembly 42 is connected to the tool assembly 3. Under the interaction of the magnetic fields of the stator assembly 40 and the rotor assembly 42, the rotor assembly 42 can rotate, and then drive the tool assembly 3 to rotate, realizing the processing of the food inside the cup body assembly 2. Among them, the rotor assembly 42 is disposed on one side of the stator assembly 40 axially. Through the axial flux coupling principle, the separation of the rotor assembly 42 and the stator assembly 40 is realized. At the same time, it can also reduce the axial thickness of the motor 4 and the weight of the motor 4, which is beneficial to reducing the overall height of the food processor 100 and facilitating the storage and transportation of the food processor 100. In addition, by separately disposing the stator assembly 40 and the rotor assembly 42, there is no need to set a connecting shaft to pass through the cup body assembly 2 to realize power transmission, improving the sealing performance of the cup body assembly 2 and reducing the noise during the operation of the food processor 100.

[0119] It can be understood that the motor 4 utilizes the axial flux principle, with the rotor assembly 42 disposed on one axial side of the stator assembly 40, and the magnetic flux direction being axial. The motor 4 has the characteristics of being structurally compact, small in size, and light in weight, and thus can reduce the overall weight and volume of the food processor 100.

[0120] Optionally, the motor 4 includes an axial flux motor. According to an embodiment of the present application, optionally, along the axis direction of the rotation of the rotor assembly 42, the gap between the rotor assembly 42 and the stator assembly 40 is greater than 0 mm and less than or equal to 5 mm.

[0121] In this embodiment, if the axial gap between the rotor assembly 42 and the stator assembly 40 is too large, it will affect the transfer of magnetic flux linkage and torque between the two, reducing the efficiency of the motor 4. If it is compensated by increasing the number of turns of the inductor and increasing the magnetic flux, it will lead to too high costs. Therefore, along the axis direction of the rotation of the rotor assembly 42, the gap between the rotor assembly 42 and the stator assembly 40 is set to be less than or equal to 5 mm, ensuring the performance of the motor 4 such as inductance, resistance, starting torque, and magnetic flux linkage.

[0122] Optionally, along the axis direction of the rotation of the rotor assembly 42, the gap between the rotor assembly 42 and the stator assembly 40 is greater than or equal to 0.5 mm and less than or equal to 5 mm.

[0123] In a specific application, the axial gap between the rotor assembly 42 and the stator assembly 40 is set to any value among 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, and 4.5 mm.

[0124] As Figure 5 shown, according to an embodiment of the present application, optionally, the rotor assembly 42 includes: a first magnetic conductive cover 420 fixedly connected to the tool assembly 3; a second magnetic conductive cover 422 connected to the first magnetic conductive cover 420 and enclosing an installation cavity with the first magnetic conductive cover 420; a first magnetic member 424 disposed in the installation cavity. The N pole of the rotor assembly 42 includes the N pole of the first magnetic member 424, and the S pole of the rotor assembly 42 includes the S pole of the first magnetic member 424.

[0125] In this embodiment, the rotor assembly 42 includes a first magnetic conductive cover 420, a second magnetic conductive cover 422, and a first magnetic member 424. The first magnetic conductive cover 420 and the second magnetic conductive cover 422 are connected to enclose an installation cavity, and the first magnetic member 424 is disposed in the installation cavity, realizing the limitation and installation of the first magnetic member 424. At the same time, the arrangement of the first magnetic conductive cover 420 and the second magnetic conductive cover 422 also ensures the magnetic flux effect, thereby ensuring the driving performance of the motor 4. The N pole of the rotor assembly 42 includes the N pole of the first magnetic member 424, and the S pole of the rotor assembly 42 includes the S pole of the first magnetic member 424. The N pole of the stator assembly 40 points to the S pole of the first magnetic member 424 along the rotation axis direction of the rotor assembly 42, and the N pole of the first magnetic member 424 points to the S pole of the stator assembly 40 along the rotation axis direction of the rotor assembly 42, causing the first magnetic member 424 to rotate circumferentially.

[0126] Specifically, the N pole of the rotor assembly 42 is the N pole of the first magnetic member 424, and the S pole of the rotor assembly 42 is the S pole of the first magnetic member 424. The magnetic lines of force inside the first magnetic member 424 point from the S pole of the first magnetic member 424 to the N pole of the first magnetic member 424 along the circumferential direction of the first magnetic member 424. The N pole of the stator assembly 40 points to the S pole of the first magnetic member 424 along the rotation axis direction of the rotor assembly 42, and the N pole of the first magnetic member 424 points to the S pole of the stator assembly 40 along the rotation axis direction of the rotor assembly 42.

[0127] It can be understood that the first magnetic conductive cover 420 and the second magnetic conductive cover 422 are made of magnetic conductive materials.

[0128] Optionally, the first magnetic member 424 includes a permanent magnet.

[0129] Optionally, the first magnetic member 424 can be a single permanent magnet in a ring shape or a disc shape, or can be composed of multiple permanent magnets assembled into a ring shape or a disc shape.

[0130] Optionally, through the adsorption between the permanent magnet and the stator core 400 of the stator assembly 40, the positioning of the cup assembly 2 and the base assembly 1 can also be realized.

[0131] According to an embodiment of the present application, optionally, the first magnetic member 424 is in a disc shape or the first magnetic member 424 is in a ring shape.

[0132] In this embodiment, the first magnetic member 424 can be in a disc shape, which can improve the magnetic flux and torque of the motor 4; the first magnetic member 424 can also be in a ring shape, which can conduct heat through the hollow part to ensure a lower temperature rise of the motor 4, slow down the aging speed of the materials of the motor 4, and improve the operation stability and service life of the motor 4.

[0133] Such as Figure 4As shown, according to an embodiment of the present application, optionally, the base assembly 1 includes: a first base body 10, a stator assembly 40 is disposed within the first base body 10 and is disposed opposite to the rotor assembly 42 in the vertical direction; an isolation cover 14 is disposed on the top of the first base body 10, and the cup assembly 2 can be placed on the isolation cover 14.

[0134] In this embodiment, the base assembly 1 includes a first base body 10 and an isolation cover 14. The isolation cover 14 is disposed on the top of the first base body 10, and the cup assembly 2 can be placed on the isolation cover 14. Thus, the rotor assembly 42 within the cup assembly 2 can interact with the stator assembly 40 disposed within the first base body 10 to drive the tool assembly 3. At the same time, the isolation cover 14 realizes the separation between the stator assembly 40 and the rotor assembly 42, reduces or eliminates the eddy current phenomenon between the two, and thereby improves the magnetic field coupling performance between the stator assembly 40 and the rotor assembly 42.

[0135] It can be understood that the isolation cover 14 can eliminate the eddy current between the stator assembly 40 and the rotor assembly 42 to improve the magnetic field coupling performance. At the same time, the isolation cover 14 can also keep the stator assembly 40 and the rotor assembly 42 spaced apart.

[0136] According to an embodiment of the present application, optionally, the isolation cover 14 includes a non-metallic member; and / or along the rotation axis direction of the rotor assembly 42, the thickness of the isolation cover 14 is less than or equal to 5 mm. And / or along the axial direction of the rotor assembly 42, the surface of the isolation cover 14 facing the cup assembly 2 is lower than the surface of the first base body 10 facing the cup assembly 2.

[0137] In this embodiment, the isolation cover 14 includes a non-metallic member. Disposing a non-metallic member between the rotor assembly 42 and the stator assembly 40 can reduce or eliminate the eddy current phenomenon between the two, and thereby improve the magnetic field coupling performance between the stator assembly 40 and the rotor assembly 42. Among them, if the thickness of the isolation cover 14 is too large, it will affect the transmission of magnetic flux linkage and torque between the stator assembly 40 and the rotor assembly 42, reducing the efficiency of the motor 4. Therefore, the thickness of the isolation cover 14 is set to be less than or equal to 5 mm to ensure the reliability of torque transmission between the stator assembly 40 and the rotor assembly 42 while reducing or eliminating eddy currents.

[0138] Optionally, the surface of the isolation cover 14 in contact with the cup assembly 2 is a smooth and continuous plane, curved surface or arc surface, which is easy to clean.

[0139] Optionally, when the cup assembly 2 is placed on the isolation cover 14, it can be placed in any direction of 360° circumferentially, without the user spending time to accurately align the position, which is very convenient to use.

[0140] Optionally, an opening 12 is provided on the first base body 10, and the isolation cover 14 is arranged at the opening 12. Specifically, along the axial direction of the rotor assembly 42, the surface of the isolation cover 14 facing the cup body assembly 2 is lower than the surface of the first base body 10 facing the cup body assembly 2, so that the isolation cover 14 is lower than the first base body 10, and thus a groove can be formed at the opening 12, facilitating the cooperation between the cup body assembly 2 and the base assembly 1.

[0141] Of course, the first base body 10 may not be provided with the opening 12, that is, the top of the first base body 10 is directly a flat surface. For example, the isolation cover 14 and the first base body 10 may be integrally formed, and the first base body 10 does not need to be provided with the opening 12. Or the first base body 10 is directly integrally formed into a flat surface, and the isolation cover 14 is arranged on the flat surface.

[0142] Optionally, the thickness of the isolation cover 14 is greater than or equal to 1 mm and less than or equal to 3.5 mm.

[0143] Optionally, the thickness of the isolation cover 14 is equal to any value of 1.5 mm, 2 mm, 2.5 mm, or 3 mm.

[0144] Optionally, the isolation cover 14 includes a high-temperature non-metallic part.

[0145] As Figure 1 shown, according to an embodiment of the present application, optionally, the base assembly 1 further includes: a damping member 16, arranged between the stator assembly 40 and the first base body 10, and at the bottom of the first base body 10.

[0146] In this embodiment, the base assembly 1 further includes a damping member 16. The damping member 16 is arranged between the stator assembly 40 and the first base body 10, and is arranged at the bottom of the first base body 10, which can reduce the vibration generated when the stator assembly 40 works, and further reduce the noise when the food processor 100 works.

[0147] Optionally, the damping member 16 includes a rubber part or a silica gel part.

[0148] As Figure 1 shown, according to an embodiment of the present application, optionally, the cup body assembly 2 further includes: a cup body 20; a second base body 22, arranged at one end of the cup body 20, enclosing a cavity 24 with the cup body 20; a cutter assembly 3 arranged in the cavity 24, and dividing the cavity 24 into a first cavity 240 and a second cavity 242. A part of the cutter assembly 3 is arranged in the first cavity 240, and another part extends into the second cavity 242. The rotor assembly 42 is arranged in the second cavity 242 and is connected to the cutter assembly 3; a seal 26, arranged at the connection between the cup body 20 and the second base body 22, for sealing the second cavity 242.

[0149] In this embodiment, the cup assembly 2 further includes a cup body 20, a second seat body 22, and a seal 26. The second seat body 22 and the cup body 20 enclose a cavity 24. The cutter assembly 3 is disposed in the cavity 24 and divides the cavity 24 into a first cavity 240 and a second cavity 242. The first cavity 240 is used to hold food ingredients. A part of the cutter assembly 3 extends into the first cavity 240, and the other part is located in the second cavity 242 and is connected to the rotor assembly 42 in the second cavity 242. The rotor assembly 42 drives the cutter assembly 3 to rotate, driving the part of the cutter assembly 3 located in the first cavity 240 to rotate, so as to process the food ingredients in the first cavity 240. Wherein, a seal 26 is provided at the connection between the second seat body 22 and the cup body 20, realizing the sealing of the second cavity 242, and further enabling the entire cup assembly 2 to be washed with water, improving the convenience of cleaning.

[0150] It can be understood that a sealing structure is also provided between the cutter assembly 3 and the cup body 20, so that the first cavity 240 is not communicated with the second cavity 242, thereby preventing the food ingredients or liquid in the first cavity 240 from flowing into the second cavity 242 and affecting the operation of the food processor 100.

[0151] Optionally, the seal 26 includes a rubber part or a silica gel part.

[0153] In this embodiment, the cutter assembly 3 includes a rotating shaft 30 and a cutter 32. A part of the rotating shaft 30 is located in the first cavity 240 and is used to install the cutter 32. A part of the rotating shaft 30 is located in the second cavity 242 and is used to connect the rotor assembly 42, thereby realizing the processing of food ingredients by the cutter 32 through the rotation of the rotor assembly 42.

[0154] As Figure 1 and Figure 3 shown, according to an embodiment of the present application, optionally, the cutter assembly 3 further includes: a chassis 34, disposed in the cavity 24 and dividing the cavity 24 into a first cavity 240 and a second cavity 242, and the rotating shaft 30 passes through the chassis 34.

[0155] In this embodiment, the tool assembly 3 further includes a chassis 34. The chassis 34 is disposed in the cavity 24 and divides the cavity 24 into a first cavity 240 and a second cavity 242, achieving the separation of food ingredients from structural components such as the rotor assembly 42. The rotating shaft 30 passes through the chassis 34, and further transmits the driving force of the rotor assembly 42 in the second cavity 242 to the tool 32 in the first cavity 240.

[0156] Optionally, a sealing structure is provided between the chassis 34 and the cup body 20.

[0157] Optionally, the chassis 34 includes a magnetically permeable member (such as the first magnetically permeable member 5 or the second magnetically permeable member 7)

[0158] It can be understood that a sealing structure is provided between the rotating shaft 30 and the chassis 34 to prevent the liquid or food ingredients in the first cavity 240 from entering the second cavity 242.

[0159] As Figure 4 shown, according to an embodiment of the present application, optionally, the second base body 22 includes a first mating surface 220, and the isolation cover 14 includes a second mating surface 140. The first mating surface 220 can be in limiting fit with the second mating surface 140.

[0160] In this embodiment, the second base body 22 includes a first mating surface 220, and the isolation cover 14 includes a second mating surface 140. The first mating surface 220 and the second mating surface 140 can be in limiting fit to achieve the accurate positioning of the cup body assembly 2 and the base assembly 1, ensure the relative positions of the stator assembly 40 and the rotor assembly 42, and further ensure the magnetic interaction between the stator assembly 40 and the rotor assembly 42.

[0162] In this embodiment, the first mating surface 220 can be a convex surface, a concave surface or a flat surface. Correspondingly, the second mating surface 140 is a convex surface, a concave surface or a flat surface that can cooperate with the first mating surface 220.

[0163] For example, when the first mating surface 220 is a convex surface, the second mating surface 140 is a concave surface; when the first mating surface 220 is a concave surface, the second mating surface 140 is a convex surface; when the first mating surface 220 is a flat surface, the second mating surface 140 is a flat surface.

When winding grooves 4000 are opened at both ends of the stator core 400, the winding portions 4042 can be provided at both ends of the stator core 400 simultaneously.

[0189] As Figure 6 shown, according to an embodiment of the present application, optionally, a flanging structure 4046 is provided at one end of the winding portion 4042 away from the base 4040, and the winding portion 4042 is located between the flanging structure 4046 and the base 4040.

[0190] In this embodiment, a flanging structure 4046 is provided at one end of the winding portion 4042 away from the base 4040. The flanging structure 4046 and the base 4040 and the winding portion 4042 together construct a limiting space. The coil 406 is disposed in the limiting space and is wound around the winding portion 4042, which can ensure the stable installation of the coil 406 and prevent the coil 406 from falling off.

[0191] As Figure 6 shown, according to an embodiment of the present application, optionally, a plurality of heat dissipation holes 4020 are provided on the side wall of the third seat body 402.

[0192] In this embodiment, a plurality of heat dissipation holes 4020 are provided on the side wall of the third seat body 402, which can improve the heat dissipation efficiency of the stator assembly 40 in the third seat body 402, thereby improving the heat dissipation effect of the motor 4, slowing down the aging speed of the motor 4, and increasing the service life of the motor 4.

[0193] Optionally, the heat dissipation holes 4020 are evenly distributed along the circumferential direction of the third seat body 402.

[0194] According to an embodiment of the present application, optionally, the stator core 400 is in a disc shape or the stator core 400 is in an annular shape.

[0195] In this embodiment, the stator core 400 is in a disc shape, which can achieve high magnetic flux and high torque, thereby improving the driving effect on the tool assembly 3. The stator core 400 can also be in an annular shape, and the hollow part can increase the heat dissipation effect and slow down the aging speed of the motor 4.

[0196] It should be noted that the food processor includes a wall breaker, a soymilk maker, a baby food maker, etc.

[0197] In a specific application, the food processor 100 (upper rotor whipping cup) is composed of a cup body 20, a tool assembly 3, a sealing cover of the cup body 20 (such as the second seat body 22), a motor 4, and a drive control base 4040 (such as the base assembly 1); the chassis 34 (heating plate) is fixed on the blade fixing shaft (such as the rotating shaft 30) through two sliding bearings 36 and an end face bearing 38. After positioning with a circlip, the assembled bearing assembly is fixedly connected and locked to the blade fixing support plate 39 through the shaft and the bearing with a screw. The rotor assembly 42 is fixed on the rotating shaft 30 with a screw 426, and the blade and the fixing nut are locked on the blade fixing shaft. Then, the bottom cover of the cup is sealed on the whipping cup body (such as the cup body 20).

[0198] For the base assembly 1 and the touch control assembly of the food processor 100, the upper cover of the motor bottom shell (such as the isolation cover 14) is fixed on the upper cover of the base 4040 (such as the first seat body 10), and then the stator assembly 40 is placed inside. After winding the copper wire (such as the coil 406) around the motor stator bracket 404 (such as the bracket 404), it is sleeved into the stator core 400. After making the motor assembly, the motor assembly is locked to the four screw posts on the upper cover of the base 4040 with screws. Then, the damping silicone pads are placed at the bottom cover of the base 4040 and the damping silicone feet of the base 4040 and fixed.

[0199] Optionally, the rotor assembly 42 is located between the blade fixed shaft and the second base body 22, and the stator assembly 40 is within the motor fixed housing of the base assembly 1.

[0200] In this application, through the principle of axial magnetic field coupling, the separation of the stator / rotor is achieved. The rotor assembly 42 is fixedly connected to the blade fixed shaft, and positioning is carried out by means of magnetic attraction between the outer rings of the stator / rotor and silk screening on the upper plane of the structure, realizing precise alignment and positioning, and crushing and whipping the food ingredients.

[0201] Optionally, the motor is of a split structure. The rotor assembly 42 is placed inside the cup body 20, and the stator assembly 40 is placed inside the base assembly 1, enabling a new type of wall breaker (without a coupling between the cup body 20 and the base assembly 1), where the rotor (on the motor) in the cup body 20 is separated from the stator in the base assembly 1.

[0202] Optionally, the upper cover of the base 4040 can be a convex plane, a concave plane, an arc surface, or a horizontal plane; the cover of the cup bottom base 4040 (such as the second base body 22) can be a convex plane, a concave plane, an arc surface, or a horizontal plane.

[0203] Optionally, the rotor assembly 42 is connected and fixed to the blade fixed shaft through fixing screws 426. The heating plate (such as the chassis 34), the blade (such as the cutter 32), the rotating bearing, the end face bearing 38, and the fixing bracket 404 of the chassis 34 are combined into a rotor blade assembly (such as the cutter assembly 3).

[0204] Optionally, the separation of the stator assembly 40 and the rotor assembly 42 is achieved by using the principle of axial flux magnetic coupling. Optionally, the rotor assembly 42 and the stator assembly 40 are of a hollow annular structure. The hollow cylinder provides diversion and heat dissipation, ensuring that the temperature rise of the motor 4 is low, slowing down the aging of the motor 4 materials, and improving the operating stability and the life of the motor 4; another type can be: the rotor assembly 42 is of a full disk structure, and the stator assembly 40 is hollow, which can enhance the magnetic flux, magnetic linkage, and the starting torque of the motor 4, improving the crushing and whipping performance of the food processor 100; the third type is: both the rotor assembly 42 and the stator assembly 40 are of a full disk structure, achieving high magnetic flux and high torque.

[0205] Optionally, the positioning method between the cup body 20 assembly and the base 4040 assembly can adopt polygon / 3-point positioning or positioning groove positioning (the coupling is cancelled).

[0206] Optionally, axial flux magnetic coupling + magnetic attraction positioning is adopted to achieve adaptive positioning and alignment between the rotor assembly 42 and the stator assembly 40.

[0207] Optionally, the cup body 20 and the second base body 22 are of a fully sealed cup body 20 structure, enabling the whole body of the cup body 20 to be washed with water and cleaned in a dishwasher.

[0208] Optionally, the stator base 4040 (such as the third body 402) and the stator wire holder (such as the bracket 404) are made of polyphenylene sulfide (PPS), the stator core 400 is made of silicon steel sheets, the rotor sheath (such as the first magnetic conductive cover 420 and the second magnetic conductive cover 422) is made of aluminum, the high-performance permanent magnet (such as the first magnetic member 424) is made of neodymium iron boron. The stator core 400 includes multiple layers of punching sheets, the multiple layers of punching sheets enclose a central through hole, and the multiple layers of punching sheets are stacked and distributed outward in the radial direction of the central through hole. The stator core 400 proposed by the present invention includes multiple layers of punching sheets, and the multiple layers of punching sheets are stacked and distributed in the radial direction of the stator core 400, thereby effectively reducing the magnetic resistance of the stator core 400, reducing magnetic loss, and further improving the efficiency of the motor 4; making the magnetic circuit of the stator core 400 shorter, the motor 4 can be made more flat and thinner, and the miniaturization of the motor can be realized. Specifically, the punching sheets can be made of strip-shaped iron sheets.

[0209] Optionally, the gap between the rotor assembly 42 and the stator assembly 40 is maintained between 0.5 mm and 5 mm (≤5 mm), otherwise it will affect the parameters of the motor 4, such as parameters like inductance, resistance, starting torque, magnetic flux, etc. If the gap between the rotor assembly 42 and the stator assembly 40 is ≥5 mm, the magnetic flux and torque will be reduced, and the efficiency of the motor 4 will be lowered. If it is compensated by increasing the number of inductance turns and increasing the magnetic flux, the cost will be relatively high.

[0210] Optionally, a high-temperature non-metallic material (such as the isolation cover 14) is used to separate the stator assembly 40 and the rotor assembly 42, and the thickness is controlled between 1 mm and 3.5 mm (≤5 mm), basically eliminating the eddy current generated axially and improving the magnetic field coupling performance.

[0211] The food processor 100 proposed in this application eliminates two main noise sources, namely the coupling and the fan of the motor 4, among the three major noise sources, solves the problems of difficult alignment and positioning, and achieves the effect of being thin, light and easy to store.

[0212] Optionally, this application adopts an elastic damping structure to reduce and mitigate the vibration noise generated during whipping and crushing.

[0213] Optionally, when the motor 4 stops working, by controlling the original circuit and adding an outer ring metal disc (such as the second magnetic conductive member 7) to the rotor assembly 42 to generate a magnetic field and eddy current, electromagnetic heating (IH) can be realized. This solution does not require adding a control circuit, achieving heating with low cost and small volume. Optionally, in the single-tube control mode, the distance between the stator assembly 40 and the metal ring outside the rotor assembly 42 is controlled within 11.5 mm ± 0.5 mm; optionally, an NS rotating magnetic ring disc can also be arranged outside the rotor assembly 42. The motor 4 drives the rotor assembly 42 and the NS rotating magnetic ring disc to rotate, generating a rotating magnetic field to achieve heating. The distance between the stator assembly 40 and the NS rotating magnetic ring disc is controlled within 3.5 mm ± 1.5 mm.

[0214] According to an embodiment of the present application, a motor 4 is further provided, including: a stator assembly 40; a rotor assembly 42, the stator assembly 40 can drive the rotor assembly 42 to rotate. Among them, the magnetic force lines between the stator assembly 40 and the rotor assembly 42 point from the N pole of the stator assembly 40 to the S pole of the rotor assembly 42 along the rotation axis direction of the rotor assembly 42, and from the N pole of the rotor assembly 42 to the S pole of the stator assembly 40; the magnetic force lines inside the stator assembly 40 point from the S pole of the stator assembly 40 to the N pole of the stator assembly 40 along the circumferential direction of the stator assembly 40, and the magnetic force lines inside the rotor assembly 42 point from the S pole of the rotor assembly 42 to the N pole of the rotor assembly 42 along the circumferential direction of the rotor assembly 42.

[0215] In the motor 4 proposed according to the present application, the magnetic force lines inside the stator assembly 40 point from the S pole of the stator assembly 40 to the N pole of the stator assembly 40 along the circumferential direction of the stator assembly 40, so that the magnetic field of the stator assembly 40 rotates circumferentially. The N pole of the stator assembly 40 generates a repulsive force on the N pole of the rotor assembly 42, the S pole of the stator assembly 40 generates an attractive force on the N pole of the rotor assembly 42, the S pole of the stator assembly 40 generates a repulsive force on the N pole of the rotor assembly 42, the N pole of the stator assembly 40 generates an attractive force on the S pole of the rotor assembly 42. The electromagnetic forces on the N pole and S pole of the rotor assembly 42 in the axial direction of the rotor assembly 42 cancel each other out, and the resultant force direction is the electromagnetic force in the circumferential direction. Therefore, when the magnetic field of the stator assembly 40 rotates circumferentially, the rotor assembly 42 will also rotate in the same direction. Furthermore, under the action of the stator assembly 40, the rotation of the rotor assembly 42 is realized. Through the rotation of the rotor assembly 42, the output of the driving force is realized. In addition, through the magnetic field distribution of the stator assembly 40 and the rotor assembly 42, the axial magnetic flux of the motor 4 is realized, and then the stator assembly 40 and the rotor assembly 42 can be arranged separately along the axial direction. When the user stores them, the part with the stator assembly 40 and the part with the rotor assembly 42 can be stored separately, improving the convenience of storage and carrying.

[0216] It can be understood that the stator assembly 40 has a coil 406, and the magnetic field generated by passing three-phase alternating current through the coil 406 rotates circumferentially.

[0217] Optionally, when the magnetic field of the stator assembly 40 rotates circumferentially, the rotor assembly 42 also rotates in the same direction and at the same speed.

[0218] It can be understood that the stator assembly 40 has a plurality of N poles (such as N pole ① and N pole ②) and a plurality of S poles. Specifically, as Figure 9 and Figure 10 shown, the N pole ① of the stator assembly 40 generates an attractive force with the N pole of the rotor assembly 42. The S poles of the stator assembly 40 generate an attractive force and a repulsive force on the N pole and S pole of the rotor assembly 42 respectively. The N pole ② of the stator assembly 40 generates an attractive force on the S pole of the rotor assembly 42. The electromagnetic forces in the axial direction on the N pole and S pole of the rotor assembly 42 cancel each other out, and the resultant force is only the electromagnetic force in the circumferential direction. Therefore, when the magnetic field of the stator assembly 40 rotates circumferentially, the rotor assembly 42 also rotates in the same direction and at the same rotational speed.

[0219] In some possible designs, along the axis direction of the rotation of the rotor assembly 42, the rotor assembly 42 is located on one side of the stator assembly 40.

[0220] In this design, the rotor assembly 42 is arranged on one side of the stator assembly 40 axially. Through the axial flux coupling principle, the separation of the rotor assembly 42 and the stator assembly 40 is achieved. At the same time, it can also reduce the axial thickness of the motor 4 and the weight of the motor 4, which is beneficial to reducing the overall height of the food processor 100 and facilitating the storage and transportation of the motor 4. In addition, separating the stator assembly 40 and the rotor assembly 42 does not require a connecting shaft to pass through the cup body assembly 2 to achieve power transmission, improving the sealing performance of the cup body assembly 2 and reducing the noise during the operation of the food processor 100.

[0221] It can be understood that the motor 4 uses the axial flux principle to arrange the rotor assembly 42 on one side of the stator assembly 40 axially. The magnetic flux direction is axial. The motor 4 has the characteristics of being structurally compact, small in size, and light in weight. Therefore, it can reduce the overall weight and volume of the food processor 100.

[0222] Optionally, the motor 4 includes an axial flux motor.

[0223] In some possible designs, along the axis direction of the rotation of the rotor assembly 42, the gap between the rotor assembly 42 and the stator assembly 40 is greater than 0 mm and less than or equal to 5 mm.

[0224] In this design, if the axial gap between the rotor assembly 42 and the stator assembly 40 is too large, it will affect the transfer of magnetic flux and torque between the two, reducing the efficiency of the motor 4. If it is compensated by increasing the number of turns of the inductor and the magnetic flux, it will lead to too high costs. Therefore, along the axis of rotation of the rotor assembly 42, the gap between the rotor assembly 42 and the stator assembly 40 is set to be less than or equal to 5 mm, ensuring the performance of the motor 4 such as inductance, resistance, starting torque, and magnetic flux.

[0225] Optionally, along the axis of rotation of the rotor assembly 42, the gap between the rotor assembly 42 and the stator assembly 40 is greater than or equal to 0.5 mm and less than or equal to 5 mm.

[0226] In a specific application, the axial gap between the rotor assembly 42 and the stator assembly 40 is set to any value among 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, and 4.5 mm.

[0227] As Figure 5 shown, in some possible designs, the rotor assembly 42 includes: a first magnetic conductive cover 420; a second magnetic conductive cover 422, connected to the first magnetic conductive cover 420 and enclosing an installation cavity with the first magnetic conductive cover 420; a first magnetic member 424, disposed in the installation cavity, the N pole of the rotor assembly 42 includes the N pole of the first magnetic member 424, and the S pole of the rotor assembly 42 includes the S pole of the first magnetic member 424.

[0228] In this design, the rotor assembly 42 includes a first magnetic conductive cover 420, a second magnetic conductive cover 422, and a first magnetic member 424. The first magnetic conductive cover 420 and the second magnetic conductive cover 422 are connected and enclose an installation cavity. The first magnetic member 424 is disposed in the installation cavity, realizing the limitation and installation of the first magnetic member 424. At the same time, the setting of the first magnetic conductive cover 420 and the second magnetic conductive cover 422 also ensures the magnetic flux effect, thereby ensuring the driving performance of the motor 4. The N pole of the rotor assembly 42 includes the N pole of the first magnetic member 424, and the S pole of the rotor assembly 42 includes the S pole of the first magnetic member 424. The N pole of the stator assembly 40 points to the S pole of the first magnetic member 424 along the axis of rotation of the rotor assembly 42, and the N pole of the first magnetic member 424 points to the S pole of the stator assembly 40 along the axis of rotation of the rotor assembly 42, causing the first magnetic member 424 to rotate circumferentially.

[0229] Specifically, the N pole of the rotor assembly 42 is the N pole of the first magnetic member 424, and the S pole of the rotor assembly 42 is the S pole of the first magnetic member 424. The magnetic lines of force inside the first magnetic member 424 point from the S pole to the N pole of the first magnetic member 424 along the circumferential direction of the first magnetic member 424. The N pole of the stator assembly 40 points to the S pole of the first magnetic member 424 along the rotation axis direction of the rotor assembly 42, and the N pole of the first magnetic member 424 points to the S pole of the stator assembly 40 along the rotation axis direction of the rotor assembly 42.

[0230] It can be understood that the first magnetic cover 420 and the second magnetic cover 422 are made of a magnetic material.

[0231] Optionally, the first magnetic member 424 includes a permanent magnet.

[0232] Optionally, the first magnetic member 424 can be a single permanent magnet in the shape of a ring or a disk, or can be formed by splicing multiple permanent magnets into a ring or a disk.

[0233] In some possible designs, the first magnetic member 424 is in the shape of a disk or the first magnetic member 424 is in the shape of a ring.

[0234] In this design, the first magnetic member 424 can be in the shape of a disk, which can improve the magnetic flux and torque of the motor 4; the first magnetic member 424 can also be in the shape of a ring, which can conduct heat through the hollow part to ensure a lower temperature rise of the motor 4, slow down the aging speed of the materials of the motor 4, and improve the operating stability and lifespan of the motor 4.

[0235] As Figure 6 shown, in some possible designs, the stator assembly 40 includes: a stator core 400, the stator core 400 includes multiple layers of punching sheets, the multiple layers of punching sheets enclose a central through-hole, and the multiple layers of punching sheets are stacked in the radial direction of the central through-hole.

The stator tooth 4002 of the stator core 400 passes through the base 4040 from the avoidance notch 4044 on the base 4040, so that the winding portion 4042 is sleeved on the stator tooth 4002, and the coil 406 is wound around the stator tooth 4002 through the winding portion 4042. Wherein, at least one end face of the stator core 400 is provided with a plurality of winding grooves 4000 to provide a placement position for the cooperating winding portion 4042, and the winding portion 4042 and the stator core 400 are installed in an embedded manner, which can effectively reduce the volume of the stator assembly 40 and realize the minimization of the motor 4.

[0243] Specifically, the N pole of the stator assembly 40 is the N pole of the coil 406, and the S pole of the stator assembly 40 is the S pole of the coil 406.

[0248] In this design, a plurality of heat dissipation holes 4020 are arranged on the side wall of the third seat body 402, which can improve the heat dissipation efficiency of the stator assembly 40 in the third seat body 402, thereby improving the heat dissipation effect of the motor 4, slowing down the aging speed of the motor 4, and increasing the service life of the motor 4.

[0249] Optionally, the heat dissipation holes 4020 are evenly distributed along the circumferential direction of the third seat body 402.

[0250] In some possible designs, the stator core 400 is in a disc shape or the stator core 400 is in an annular shape.

[0251] In this design, the stator core 400 is in a disc shape, which can achieve high magnetic flux and high torque, thereby improving the driving effect on the tool assembly 3. The stator core 400 can also be in an annular shape, and the hollow part can increase the heat dissipation effect and slow down the aging speed of the motor 4.
