Description

Technical Field

[0001] This utility model pertains to kitchen appliances, specifically a food processing machine. Background Technology

[0002] Some existing magnetically driven food processors, for example, have a main unit equipped with a motor and a drive disk driven by the motor. The mixing blade assembly includes a blade holder with a drive disk mounted on it and mixing blades mounted above the blade holder and fixedly connected to the drive disk. The drive disk is positioned below the drive disk, thus driving the drive disk to rotate in a vacuum, achieving magnetic actuation of the mixing blades. These food processors typically use heating elements to heat the mixing cup, often fixed to the bottom wall of the mixing cup or the bottom wall of the heating plate. This results in a situation where, when the heating element and the electromagnetic drive disk located below it work together, the high-speed rotation of the motor generates heat, and the coil itself heats up, causing the temperature near the drive disk to be high. Moreover, for the metal heating plate, there will be magnetic eddy currents in the area where the drive disk and the drive disk face each other. The metal heating plate has resistance, and when current flows through the resistance, it generates heat. The magnetic eddy currents directly generate heat inside the metal heating plate, causing the metal heating plate to be superimposed with the heat from the magnetic eddy currents, the heat from the heating element, and of course, the heat from the coil of the motor, forming an abnormally high temperature zone. The stirring blade assembly is installed at the bottom of the stirring cup through a blade holder. There will inevitably be a gap between the blade holder and the bottom wall of the stirring cup, causing the slurry to flow onto the heating plate below the blade holder, and the slurry residue to be deposited on the heating plate under the action of gravity, which in turn causes the heating plate to burn in the above-mentioned abnormally high temperature zone.

[0003] Patent CN207940819U also discloses another type of air-driven magnetic food processor. Unlike the heating method and stirring blade structure mentioned above, this solution uses a magnetic moving grinding head and a grinding section that cooperates with the moving grinding head to drive the moving grinding head circumferentially using an electronic coil. An electromagnetic heating coil is located below the cup. However, in this food processor, the electromagnetic heating coil used for heating is still located at the bottom of the cup. The magnetic eddy current heat between the electronic coil and the moving grinding head is superimposed with the heat from the electromagnetic heating coil, causing the heat to concentrate at the bottom of the cup, forming an abnormally high temperature zone. The pulp residue settles at the bottom of the cup under gravity, leading to a burnt bottom problem and ultimately resulting in a burnt texture in the prepared slurry. Utility Model Content

[0004] This invention provides a food processing machine that, while achieving efficient magnetic drive and magnetic heating, solves the problems of slurry sticking to the bottom and scorched texture caused by the superposition of magnetic eddy current heat and heating element heat at the bottom of the mixing cup to form an abnormally high temperature zone.

[0005] The technical solution adopted in this utility model is as follows: This utility model provides a food processing machine, including a mixing cup, an electromagnetic drive device, a blade assembly detachably disposed within the mixing cup, and a heating element for heating the mixing cup. The blade assembly includes a blade holder supported on the bottom wall of the mixing cup, a pulverizing blade located above the blade holder, a transmission disk disposed within the blade holder, and a transmission shaft connecting the transmission disk and the pulverizing blade. The electromagnetic drive device drives the transmission disk to rotate, thereby causing the pulverizing blade to rotate. The side wall of the mixing cup includes a limiting wall surrounding the outer periphery of the blade holder and a mounting wall connected above the limiting wall. The heating element is an electromagnetic heating coil fixed to the outside of the mounting wall, and the electromagnetic heating coil is offset from the transmission disk in the height direction.

[0006] The food processing machine provided by this utility model includes a side wall of the mixing cup comprising a limiting wall surrounding the outer periphery of the blade holder and a mounting wall connected above the limiting wall. The limiting wall radially limits the blade holder, preventing it from moving, ensuring precise blade holder mounting and maintaining the precise position of the transmission disk, thus ensuring reliable drive. The mounting wall connected above the limiting wall is positioned high, causing the electromagnetic heating coil fixed to the outside of the mounting wall to be positioned high as well. This creates a vertical misalignment between the electromagnetic heating coil and the lower-positioned transmission disk. When the electromagnetic drive device and the electromagnetic heating coil work synchronously, magnetic eddy currents are generated at the bottom wall of the mixing cup between the electromagnetic drive device and the transmission disk, and a heating field is generated between the electromagnetic heating coil and the side wall of the mixing cup. The magnetic eddy currents are located below the transmission disk, while the electromagnetic heating coil is located above the transmission disk, thereby increasing the vertical distance between the electromagnetic heating coil and the magnetic eddy currents. In the radial direction, the drive disk is located inside the blade holder, and the electromagnetic heating coil is fixed on the outside of the mounting wall. The side wall of the mixing cup radially separates the electromagnetic heating coil from the drive disk, thus making the magnetic eddy currents and the electromagnetic heating coil radially distant. Therefore, not only is the vertical distance between the magnetic eddy currents and the heating field increased, but the radial distance between them is also increased. This prevents the heat from the magnetic eddy currents and the heat from the electromagnetic heating coil from superimposing on the bottom wall of the mixing cup, preventing the formation of an abnormally high temperature zone at the bottom of the mixing cup. Even if pulp residue accumulates on the bottom wall of the mixing cup during the pulverizing process, it will not directly contact the abnormally high temperature zone and cause the food to burn, thus improving the quality and taste of the pulp.

[0007] In addition, compared with heating tubes, which are thicker and occupy more space and are difficult to control, the heating method using electromagnetic heating coils allows for more flexible adjustment of the heating field within a limited installation space, so as to reasonably and accurately control the heating field and the heat superposition between magnetic eddy currents.

[0008] In a preferred embodiment, the shredder includes a lower blade fixed to the drive shaft and an upper blade located above the lower blade, the mounting wall extends upward from the limiting wall, the lower blade is at least partially located radially inside the mounting wall, and the electromagnetic heating coil extends upward from the bottom end of the mounting wall to a height not lower than the lower blade.

[0009] The lower blades of the pulverizing blade are at least partially located radially inside the mounting wall, while the electromagnetic heating coil extends upwards from the bottom of the mounting wall to a height no lower than the lower blades. This ensures that the heating field of the electromagnetic heating coil highly overlaps with the pulverizing area of ​​the pulverizing blade (where the lower blades are located). The stirring action of the lower blades allows the heat generated by the electromagnetic heating coil to be quickly dispersed, achieving efficient heating and avoiding heat concentration, thus preventing localized high temperatures and scorching. Furthermore, the electromagnetic heating coil acts directly and efficiently on the food being pulverized by the lower blades and the surrounding slurry, making full use of the limited heating and pulverizing space, improving slurry quality and pulverizing efficiency. In addition, compared to traditional heating tubes, the electromagnetic heating coil can be extended vertically as needed without simultaneously increasing the radial dimension. While satisfying the vertical heating space requirements, it does not increase the radial installation space, thus facilitating a compact structural arrangement and avoiding the problem of an excessively large mixing cup, achieving miniaturization of the mixing cup.

[0010] In a preferred embodiment, the highest point of the electromagnetic heating coil is lower than the highest point of the drive shaft.

[0011] The highest point of the electromagnetic heating coil is set lower than the highest point of the drive shaft to avoid the electromagnetic heating coil being too high, which would cause the slurry to overflow the stirring cup when it boils during the heating process. At the same time, the electromagnetic heating coil is sufficient to cover the main crushing area around the blade of the crusher, avoiding the heating coil being too low and unable to form an effective cooking area. Therefore, by reasonably arranging the height of the electromagnetic heating coil, the effective cooking of the slurry is achieved, ensuring the quality of the finished slurry.

[0012] In a preferred embodiment, the mounting wall is connected to the top of the limiting wall and extends outward at an angle from bottom to top.

[0013] This allows the electromagnetic heating coil to move away from the transmission disk synchronously in both the radial and vertical directions, further avoiding the temperature superposition between the magnetic eddy current heat and the heating field of the electromagnetic heating coil.

[0014] In a preferred embodiment, the mounting wall includes a stepped section that folds outward from the top of the limiting wall and an expansion section that extends upward from the stepped section, the electromagnetic heating coil covering the outside of the stepped section and extending to the expansion section.

[0015] By setting up a stage and an expansion section, the stage is used to move the electromagnetic heating coil further away from the transmission disk in the radial direction; the electromagnetic heating coil is wrapped around the outside of the stage and extends to the expansion section, thereby realizing heating from bottom to top and multi-directional heating from the outside to the inside in the radial direction, achieving an all-round three-dimensional heating effect, improving heating efficiency, and at the same time avoiding the formation of abnormally high temperature zones at the bottom of the stirring cup by magnetic eddy currents and electromagnetic heating fields.

[0016] In a preferred embodiment, the outer side of the stirring cup is provided with a magnetic shielding plate extending circumferentially thereon, the magnetic shielding plate isolating the electromagnetic heating coil and the transmission disk in the height direction.

[0017] By setting up a magnetic shielding plate, the magnetic field of the electromagnetic heating coil is effectively blocked from radiating downwards to the area where the transmission disk is located, avoiding unnecessary electromagnetic coupling between the magnetic field and the transmission disk and generating additional interference. At the same time, it prevents excess magnetic eddy current heat from appearing at the transmission disk due to the intervention of the magnetic field of the electromagnetic heating coil, ensuring that the magnetic field of the electromagnetic heating coil mainly acts on the heating area inside the stirring cup to achieve efficient heating. It also ensures the stability of the transmission disk when driven by the electromagnetic drive device, making the transmission reliable.

[0018] In a preferred embodiment, the electromagnetic heating coil is separated from the outer surface of the mounting wall to form a buffer space.

[0019] By separating the electromagnetic heating coil from the outer surface of the mounting wall, electromagnetic heating is achieved in the air, which heats the slurry in the stirring cup laterally. At the same time, the heat from the electromagnetic heating coil is prevented from being conducted from the side wall to the bottom wall of the stirring cup, thus preventing the formation of an abnormally high temperature zone at the bottom of the stirring cup by magnetic eddy currents and electromagnetic heating field.

[0020] In a preferred embodiment, the stirring cup includes an open glass cup and a metal heating plate encapsulated at the bottom of the glass cup. The limiting wall and the mounting wall are located on the side wall of the heating plate, and the electromagnetic heating coil is fixed to the heating plate as a whole.

[0021] In a preferred embodiment, the stirring cup is a metal cup body, the metal cup body having an integrally formed bottom wall and side walls, and the limiting wall and the mounting wall are located on the side walls of the metal cup body.

[0022] Regardless of whether the mixing cup uses a separate glass cup and heating plate combination or a one-piece metal cup body, placing the electromagnetic heating coil on the outside of the side wall of the mixing cup keeps the electromagnetic heating coil away from the magnetic eddy current region. This prevents the heat radiation from the electromagnetic heating coil from superimposing on the magnetic eddy current region, thus preventing scorching at the bottom of the mixing cup. Using a glass cup allows for visualization of the pulping process, improving the user experience. The electromagnetic heating coil and heating plate are fixed as one piece, allowing for modular assembly of the electromagnetic heating coil and heating plate within the glass cup, facilitating convenient assembly. The one-piece metal cup body has a simple structure and low manufacturing cost.

[0023] In a preferred embodiment, the electromagnetic drive device includes a motor and a drive disk driven by the motor, the drive disk being positioned directly below the transmission disk.

[0024] By employing a motor and a drive disk driven by the motor, a drive disk can be added to the existing motor of a traditional food processor, resulting in minimal overall modification costs and enabling cost-effective improvements to the food processor while achieving efficient magnetic drive and magnetic heating. Furthermore, with the drive disk positioned directly below the transmission disk, the magnetic eddy currents generated between them move vertically away from the electromagnetic heating coil, resulting in superior anti-sticking performance.

[0025] In a preferred embodiment, the electromagnetic drive device includes a drive coil that generates a magnetic field when energized, the drive coil being fixed to the outside of the limiting wall and surrounding the outer periphery of the transmission disk.

[0026] By employing a drive coil, which is fixed to the outside of the limiting wall and surrounds the outer periphery of the transmission disk, the structure of the electromagnetic drive device is simplified, while the overall height is reduced, achieving miniaturization of the entire machine. Of course, on this basis, the magnetic eddy current between the drive coil and the transmission disk is still highly misaligned with the electromagnetic heating coil, and the magnetic eddy current is transferred to the side wall of the stirring cup, thereby avoiding the problem of slurry residue settling at the bottom of the stirring cup and causing scorching, thus improving the taste of the slurry.

[0030] Many specific details are set forth in the following description to provide a full understanding of the present invention.

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

[0034] like Figure 1-4 As shown, this utility model provides a food processing machine, including a mixing cup 10, an electromagnetic drive device 20, a blade assembly 30 detachably disposed within the mixing cup 10, and a heating element for heating the mixing cup 10. The blade assembly 30 includes a blade holder 31 supported on the bottom wall of the mixing cup 10, a pulverizing blade 32 located above the blade holder 31, a transmission disk 33 disposed within the blade holder 31, and a transmission shaft 34 connecting the transmission disk 33 and the pulverizing blade 32. The electromagnetic drive device 20 drives the transmission disk 33 to rotate, thereby driving the pulverizing blade 32 to rotate. The side wall of the mixing cup 10 includes a limiting wall 101 surrounding the outer periphery of the blade holder 31 and a mounting wall 102 connected above the limiting wall 101. The heating element is an electromagnetic heating coil 60 fixed to the outside of the mounting wall 102, and the electromagnetic heating coil 60 is offset from the transmission disk 33 in the height direction.

[0035] It should be noted that this utility model does not limit the specific structure of the food processing machine, for example... Figure 1 As shown, the food processor also includes a main unit 40, a mixing cup 10 detachably mounted on top of the main unit 40, and an electromagnetic drive device 20 disposed inside the main unit 40. In other embodiments, the food processor is an integrated cup and machine type, with the motor fixed to the bottom of the mixing cup 10.

[0036] The food processing machine provided by this utility model includes a limiting wall 101 surrounding the outer periphery of the blade holder 31 and a mounting wall 102 connected above the limiting wall 101. The limiting wall 101 radially limits the blade holder 31, preventing the blade holder 31 from moving, ensuring that the blade holder 31 is accurately installed and that the position of the transmission disk 33 is accurate, and that the drive is reliable. The mounting wall 102, connected above the limiting wall 101, is positioned at a high position, causing the electromagnetic heating coil 60, fixed to the outside of the mounting wall 102, to be positioned at a high position. Consequently, the electromagnetic heating coil 60 and the transmission disk 33, positioned at a low position, are misaligned in the height direction. When the electromagnetic drive device 20 and the electromagnetic heating coil 60 operate synchronously, magnetic eddy currents are generated at the bottom wall of the stirring cup 10 between the electromagnetic drive device 20 and the transmission disk 33, and a heating field is generated between the electromagnetic heating coil 60 and the side wall of the stirring cup 10. The magnetic eddy currents are located below the transmission disk 33, while the electromagnetic heating coil 60 is located above the transmission disk 33, thereby increasing the vertical distance between the electromagnetic heating coil 60 and the magnetic eddy currents. In addition, in the radial direction, the transmission disk 33 is located inside the blade holder 31, and the electromagnetic heating coil 60 is fixed on the outside of the mounting wall 102. The side wall of the stirring cup 10 radially separates the electromagnetic heating coil 60 from the transmission disk 33, thereby making the magnetic eddy current and the electromagnetic heating coil 60 radially distant. Therefore, not only is the vertical distance between the magnetic eddy current and the heating field increased, but the radial distance between the two is also increased, thereby preventing the heat of the magnetic eddy current and the heat of the electromagnetic heating coil from superimposing on the bottom wall of the stirring cup 10, preventing the formation of an abnormally high temperature zone at the bottom of the stirring cup 10. Even if the pulp residue accumulates on the bottom wall of the stirring cup 10 during the crushing process, it will not directly contact the abnormally high temperature zone and cause the food to burn, thus improving the quality and taste of the pulp.

[0037] Furthermore, it should be emphasized that during the research process of the magnetically driven food processing machine, the applicant also considered installing the traditional heating element on the side wall of the mixing cup, mainly to reduce the obstruction of the heating element's heat by the blade holder, thereby achieving full utilization of heat and improving heating efficiency. However, during further research, the applicant discovered for the first time the problem of an abnormally high-temperature zone forming at the bottom of the mixing cup due to the superposition of magnetic eddy current heat and heating element heat. Therefore, based on this technical problem, the applicant provided the technical means adopted in this application to solve it. Moreover, the heating method of the electromagnetic heating coil 60 provided in this application, compared with the larger and more space-consuming heating element, allows for more flexible adjustment of the heating field within a limited installation space. This makes it easier to reasonably, accurately, and effectively solve the problem of heat superposition between the heating field and magnetic eddy currents, achieving the beneficial effect of avoiding the abnormally high-temperature zone at the bottom of the mixing cup.

[0038] like Figure 3 , 4As shown, in a preferred embodiment, a magnetic shielding plate 50 extending circumferentially is provided on the outer side of the stirring cup 10, for example at the connection position of the mounting wall 102 and the limiting wall 101. The magnetic shielding plate 50 is, for example, a metal sheet, and the magnetic shielding plate 50 is isolated in the height direction between the electromagnetic heating coil 60 and the transmission disk 33.

[0039] By setting up the magnetic shielding plate 50, the magnetic field of the electromagnetic heating coil 60 is effectively blocked from radiating downwards to the area where the transmission disk 33 is located, avoiding unnecessary electromagnetic coupling between the magnetic field and the transmission disk 33 and generating additional interference. At the same time, it prevents excess magnetic eddy current heat from appearing at the transmission disk 33 due to the intervention of the magnetic field of the electromagnetic heating coil 60, ensuring that the magnetic field of the electromagnetic heating coil 60 mainly acts on the heating area inside the stirring cup 10 to achieve efficient heating, and also ensuring the stability of the transmission disk 33 when driven by the electromagnetic drive device 20, making the transmission reliable.

[0040] like Figure 3 As shown, in a preferred embodiment, the pulverizing blade 32 includes a lower blade 321 fixed to the drive shaft 34 and an upper blade 322 located above the lower blade 321. The mounting wall 102 extends upward from the limiting wall 101. The lower blade 321 is at least partially located radially inside the mounting wall 102, and the electromagnetic heating coil 60 extends upward from the bottom end of the mounting wall 102 to a height not lower than the lower blade 321.

[0041] More preferably, the highest point of the electromagnetic heating coil 60 is lower than the highest point of the drive shaft 34.

[0042] The lower blade 321 of the pulverizing blade 32 is at least partially located radially inside the mounting wall 102, while the electromagnetic heating coil 60 extends upward from the bottom of the mounting wall 102 to a height no lower than the lower blade 321. This ensures that the heating field corresponding to the electromagnetic heating coil 60 highly overlaps with the pulverizing area of ​​the pulverizing blade 32 (where the lower blade 321 is located). The stirring action of the lower blade 321 allows the heat generated by the electromagnetic heating coil 60 to be quickly dispersed, achieving efficient heating and avoiding heat concentration, thus preventing localized high temperatures and scorching. Moreover, the electromagnetic heating coil 60 acts directly and efficiently on the food being pulverized by the lower blade 321 and the surrounding slurry, making full use of the limited heating and pulverizing space, improving slurry quality, and increasing pulverizing efficiency. In addition, compared to traditional heating tubes, the electromagnetic heating coil 60 can be extended in height as needed without simultaneously increasing the radial dimension. While satisfying the vertical heating space, it does not increase the radial installation space, thus facilitating a compact structural arrangement and avoiding the problem of the mixing cup 10 being too large, achieving miniaturization of the mixing cup 10.

[0043] The highest point of the electromagnetic heating coil 60 is set lower than the highest point of the drive shaft 34 to avoid the electromagnetic heating coil 60 being too high, which would cause the slurry to overflow the stirring cup 10 when it boils during the heating process. At the same time, the electromagnetic heating coil 60 is sufficient to cover the main crushing area around the blade of the crusher 32, avoiding the heating coil being too low and unable to form an effective cooking area. Therefore, by reasonably arranging the height of the electromagnetic heating coil 60, the effective cooking of the slurry is achieved, ensuring the quality of the finished slurry.

[0044] This utility model does not limit the structure of the stirring cup 10 or the shape of the mounting wall 102. For example: Implementation Example 1, such as Figure 1-4 As shown, the stirring cup 10 includes a glass cup 11 with an open top and bottom and a metal heating plate 12 encapsulated at the bottom of the glass cup 11. The limiting wall 101 and the mounting wall 102 are located on the side wall of the heating plate 12. The electromagnetic heating coil 60 is fixed to the heating plate 12 as a whole.

[0045] Preferably, the mounting wall 102 is connected to the top of the limiting wall 101 and extends outward at an angle from bottom to top. This allows the electromagnetic heating coil 60 to move away from the transmission disk simultaneously in both the radial and vertical directions, further avoiding temperature superposition between the magnetic eddy current heat and the heating field of the electromagnetic heating coil.

[0046] Implementation Example 2, such as Figure 5 As shown, unlike Implementation Example 1, the stirring cup 10 is a metal cup body with an integrally formed bottom wall and side wall. The limiting wall 101 and the mounting wall 102 are located on the side wall of the metal cup body.

[0047] Preferably, the mounting wall 102 is connected to the top end of the limiting wall 101 and extends outward at an angle from bottom to top.

[0048] It is understandable that regardless of whether the stirring cup 10 adopts a separate glass cup 11 and heating plate 12 combination or an integrated metal cup body, by placing the electromagnetic heating coil 60 on the outside of the side wall of the stirring cup 10, the electromagnetic heating coil 60 is kept away from the magnetic eddy current region, thereby preventing the heat radiation of the electromagnetic heating coil 60 from superimposing on the magnetic eddy current region and forming a smear at the bottom of the stirring cup 10. Using a glass cup 11 allows for visualization of the pulping process, improving the user experience. The electromagnetic heating coil 60 and the heating plate 12 are fixed as one unit, allowing for modular assembly of the electromagnetic heating coil 60 and the heating plate 12 onto the glass cup 11, achieving convenient assembly. The integrated metal cup body has a simple structure and low manufacturing cost.

[0049] Implementation Example 3, such as Figure 6As shown, unlike embodiment 2, the mounting wall 102 includes a platform stage 1021 that folds outward from the top of the limiting wall 101 and an expansion section 1022 that extends upward from the platform stage 1021. The electromagnetic heating coil 60 covers the outside of the platform stage 1021 and extends to the expansion section 1022.

[0050] In this embodiment, the stirring cup 10 can adopt any of the stirring cup structures in Embodiment 1 or 2.

[0051] This embodiment example sets up a stage 1021 and an expansion section 1022. The stage 1021 is used to move the electromagnetic heating coil 60 further away from the transmission disk 33 in the radial direction. The electromagnetic heating coil 60 covers the outside of the stage 1021 and extends to the expansion section 1022, thereby realizing heating from bottom to top and multi-directional heating from the outside to the inside in the radial direction, achieving an all-round three-dimensional heating effect, improving heating efficiency, and at the same time avoiding the formation of an abnormally high temperature zone at the bottom of the stirring cup 10 by magnetic eddy currents and electromagnetic heating fields.

[0052] It should be noted that the method of fixing the electromagnetic heating coil 60 in this utility model can be as follows: the electromagnetic heating coil 60 is directly fixed and covered on the outer surface of the mounting section of the stirring cup 10; or, in a preferred embodiment, the electromagnetic heating coil 60 is separated from the outer surface of the mounting wall 102 to form a buffer space.

[0053] By separating the electromagnetic heating coil 60 from the outer surface of the mounting wall 102, electromagnetic heating is achieved in the air, which heats the slurry in the stirring cup 10 laterally. At the same time, the heat from the electromagnetic heating coil 60 is prevented from being conducted from the side wall to the bottom wall of the stirring cup 10, and the formation of an abnormally high temperature zone at the bottom of the stirring cup 10 by magnetic eddy currents and electromagnetic heating field is prevented.

[0054] This utility model does not limit the specific structure of the electromagnetic drive device 20. For example, refer to... Figure 1-4 As shown, the electromagnetic drive device 20 includes a motor and a drive disk driven by the motor, with the drive disk directly below the transmission disk 33.

[0055] By employing a motor and a drive disk driven by the motor, a drive disk can be added to the existing motor of a conventional food processor, resulting in minimal overall modification costs and enabling cost-effective improvements to the food processor while achieving efficient magnetic drive and magnetic heating. Furthermore, with the drive disk positioned directly below the transmission disk 33, the magnetic eddy currents generated between them move vertically away from the electromagnetic heating coil 60, resulting in superior anti-sticking performance.

[0056] In another preferred embodiment, the electromagnetic drive device 20 includes a drive coil that generates a magnetic field when energized, the drive coil being fixed to the outside of the limiting wall 101 and surrounding the outer periphery of the transmission disk 33.

[0057] By employing a drive coil, which is fixed to the outside of the limiting wall 101 and surrounds the outer periphery of the transmission disk 33, the structure of the electromagnetic drive device 20 is simplified, and the overall height is reduced, thus achieving miniaturization of the entire machine. Of course, on this basis, the magnetic eddy current between the drive coil and the transmission disk 33 is still highly misaligned with the electromagnetic heating coil 60, and the magnetic eddy current is transferred to the side wall of the stirring cup 10, thereby avoiding the problem of slurry residue settling at the bottom of the stirring cup 10 and causing the bottom to stick, thus improving the taste of the slurry.

[0058] For any parts not mentioned in this utility model, existing technologies can be used or referenced.

[0059] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0060] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
