[0010] In some embodiments, the support member is provided with a plurality of support ribs on the side of the support member facing the moving part along the axis of rotation of the moving part, and the support member is in contact with the moving part through the support ribs.

[0011] In this embodiment, the support member is provided with support ribs, and the support member is in contact with the moving part through the support ribs, thereby reducing the contact area between the support member and the moving part, and further reducing the degree of wear of the moving part when the moving part moves relative to the support member, and reducing the frictional resistance and frictional noise of the rotation of the moving part.

[0012] In some embodiments, the plurality of support ribs are arranged at intervals around the axis of rotation of the moving part; and / or any support rib is in the shape of a strip and extends in the radial direction of the moving part; or any support rib comprises a plurality of protrusions arranged at intervals in the radial direction of the moving part.

[0013] In this embodiment, the plurality of support ribs are arranged at intervals around the axis of rotation, thereby reliably supporting the moving part and avoiding tilting of the moving part; optionally, the support member is in the shape of a strip and extends in the radial direction of the moving part, so that the support ribs can reliably support the moving part and reduce the contact area with the moving part, thereby reducing the wear of the moving part.

[0014] In some embodiments, one of the support member and the moving part is provided with a limiting column, and the other of the support member and the moving part is sleeved on the limiting column and can rotate relative to the limiting column.

[0015] In this embodiment, one of the support member and the moving part is provided with a limiting column, and the other is sleeved on the limiting column to achieve rotational connection and radial limiting, thereby ensuring the relative position between the moving part and the support member, and further ensuring the reliability of the moving part driving the coil disc.

[0016] In some embodiments, the cooking appliance further comprises a support seat arranged in the housing, the heating container is mounted on the support seat, and the coil disc is arranged outside the support seat and opposite the bottom of the support seat; the support member is connected with the support seat or the support member is connected with the housing, and the moving part is located between the support member and the support seat.

[0017] In this embodiment, the cooking appliance also includes a support base, which is disposed within the housing and supports the heating container. A coil is located outside the support base and opposite to its bottom, allowing the coil to move up and down relative to the heating container from the bottom of the support base, thereby adjusting the heating power of the cooking appliance. The support member is connected to the support base, ensuring reliable installation and guaranteeing the reliable support of the support base for the moving parts. This also allows the support member and support base to be integrated, improving the integration of internal components and facilitating assembly. Alternatively, the support member can be connected to the housing to facilitate repair or replacement of individual components when they are severely worn.

[0018] In some embodiments, the support member may optionally include: a cover, which covers the moving part along the axis of rotation of the moving part, and is disposed on the side of the moving part away from the coil disk; and a connecting part, which is disposed on the outer wall of the cover and is connected to the support base.

[0019] In this embodiment, the support member includes a cover and a connecting part. The cover is placed over the moving part to protect it. The connecting part is connected to the support base to fix the support member to the support base.

[0020] In some embodiments, the support base is optionally provided with a first limiting part, and the coil disk is provided with a second limiting part, and the first limiting part and the second limiting part are slidably connected along the axial direction of the moving part.

[0021] In this embodiment, a first limiting part is provided on the support base, and a second limiting part is provided on the coil disk. The first limiting part and the second limiting part are slidably connected, which realizes the raising and lowering of the coil disk along a predetermined trajectory, which can prevent the radial position of the coil disk from shifting and ensure the reliability of the movement position of the coil disk.

[0022] In some embodiments, optionally, a coil is wound around the outer wall of the support base, the coil on the support base can surround the heating container, and the coil on the support base can generate a magnetic field to heat the heating container when energized.

[0023] In this embodiment, a coil is wound on the support base, and the coil on the support base surrounds the heating container. When the coil on the support base is energized, the heating container can be heated. That is, both the coil on the coil disk and the coil on the support base can heat the heating container. Optionally, the coil on the coil disk and the coil on the support base can heat the heating container simultaneously, or the coil on the coil disk and the coil on the support base can heat the heating container separately.

[0024] In some embodiments, the drive unit may be mounted on the support base or the housing.

[0025] In this embodiment, the drive unit can be installed on the support base or on the housing. When the drive unit and the support member are installed on the support base, the support base, the support member and the drive assembly are assembled together, which improves the integrated design of the internal components of the cooking appliance, thereby facilitating the assembly of the internal components of the cooking appliance and the overall assembly of the appliance.

[0026] In some embodiments, the cooking appliance may optionally include: a first detection component disposed on the support or the housing; and a second detection component disposed on the moving part, wherein the first detection component determines the position of the coil based on the second detection component.

[0027] In this embodiment, to prevent abnormal lifting and lowering of the coil, it is necessary to detect, limit, and provide feedback on the vertical movement of the coil. Therefore, a first detection component is provided on the support or housing, and a second detection component is provided on the moving part. During the process of the moving part driving the coil to move relative to the heating container, the second detection component and the first detection component on the moving part change position, thereby causing the detection parameters of the first detection component to change. The position of the coil is determined according to the detection parameters, thus realizing the detection of the coil position and ensuring the normal operation of the mechanism.

[0028] In some embodiments, the first detection component may optionally include at least one of the following: a micro switch, a reed switch, and a grating; the second detection component may include a magnet.

[0029] In this embodiment, the first detection component can be a position detection structure such as a micro switch, a reed switch, and a grating, and the second detection component includes a magnet. During the rotation of the moving part, the magnet rotates with the moving part, thereby changing the magnetic field of the magnet at the location of the first detection component, so as to realize the position detection during the movement of the coil disk.

[0030] In some embodiments, the moving part may optionally include: a first gear located at the bottom of the coil disk, the first gear having a first engaging portion, the side of the first gear facing away from the coil disk being supported by a support member; and a second gear connected to the driving part, located on one radial side of the first gear and meshing with the first gear, the driving part driving the first gear to rotate through the second gear.

[0031] In this embodiment, the moving part includes a first gear and a second gear. The second gear is connected to the driving part and is located on one radial side of the first gear, meshing with it. A first mating part is provided on the first gear, and a second mating part is provided on the coil disc. The first and second mating parts are in contact. When the driving part drives the second gear to rotate, the meshing of the first and second gears causes the first gear to rotate, which in turn causes the first mating part to rotate relative to the second mating part, thus raising and lowering the second mating part, and consequently, raising and lowering the coil disc. The cooking appliance proposed in this application, through the transmission of the first and second gears and the engagement of the first and second mating parts, achieves the conversion of power from rotation to linear lifting and lowering, improving the stability of power transmission. Furthermore, the fact that the second gear is located on one side of the first gear reduces the axial space occupied, thereby lowering the overall height of the cooking appliance.

[0032] In some embodiments, optionally, one of the first mating portion and the second mating portion includes a first protrusion and a first recess, the first protrusion and the first recess are alternately arranged along the rotation direction of the first gear, and the other of the first mating portion and the second mating portion can alternately engage with the first protrusion and the first recess to make the coil disk move up and down between the first position and the second position.

[0033] In this embodiment, the first mating part and the second mating part achieve the switching between rotational and linear movement through a concave-convex structure. One of the first and second mating parts includes a first convex part and a first concave part. As the first mating part rotates with the first gear, the other of the first and second mating parts alternately passes through the first convex part and the first concave part, thereby realizing the reciprocating lifting and lowering of the coil. When the other of the first and second mating parts engages with the first convex part, the first and second mating parts together lift the coil, bringing it closer to the heating container. When the other of the first and second mating parts engages with the first concave part, the coil descends, moving it away from the heating container.

[0034] In some embodiments, optionally, the other of the first mating portion and the second mating portion further includes a second protrusion and a second recess, the second protrusion and the second recess being alternately arranged along the rotation direction of the first gear.

[0035] In this embodiment, the other of the first mating part and the second mating part further includes a second protrusion and a second concave part. The second protrusion and the second concave part are alternately arranged along the rotation direction of the first gear, so that the second protrusion and the second concave part alternately cooperate with the first protrusion and the first concave part, which increases the lifting range of the coil, thereby increasing the adjustable range of the heating power of the cooking appliance and improving the stability of the drive between the coil and the first gear.

[0036] In some embodiments, optionally, the first protrusion and the first recess are connected sequentially along the rotation direction, or the first protrusion and the first recess are spaced apart along the rotation direction; and / or the second protrusion and the second recess are connected sequentially along the rotation direction, or the second protrusion and the second recess are spaced apart along the rotation direction; and / or the second mating part is located in the middle of the coil disk, the coil on the coil disk is located around the second mating part, or the second mating part is arranged along the radial direction of the first gear close to the side wall of the coil disk, and the second mating part surrounds the coil on the coil disk.

[0037] In this embodiment, the first protrusion and the first concave portion are sequentially connected along the rotation direction of the first gear. This makes the movement of the coil smoother during the rotation of the moving part and allows the coil to continuously rise and fall with the continuous rotation of the first gear. Consequently, the induced magnetic field of the heating container continuously changes, increasing the adjustable range of heating power during cooking. Alternatively, the first protrusion and the first concave portion can be spaced apart along the rotation direction, making the rising and falling of the coil non-continuous, achieving intermittent rising and falling of the coil. Correspondingly, the second protrusion and the second concave portion can also be sequentially connected or intermittently arranged. Optionally, the second mating portion can be located in the middle of the coil to increase the winding area of ​​the coil; the second mating portion can also be located in the radially outer part of the coil to increase the reliability and stability of the transmission.

[0038] In some embodiments, the cooking appliance may optionally further include: a rolling element disposed on at least one of the first mating portion and the second mating portion, the first mating portion and the second mating portion being in contact through the rolling element.

[0039] In this embodiment, the cooking appliance also includes a rolling element. The first mating part and the second mating part contact each other through the rolling element, so that the sliding friction between the first mating part and the second mating part is converted into rolling friction, thereby reducing the frictional resistance between the first mating part and the second mating part.

[0052] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0053] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0054] The following reference Figures 1 to 8 This invention describes a cooking appliance proposed according to some embodiments of the present invention.

[0055] likeFigure 1 , Figure 2 , Figure 3 and Figure 4 As shown, according to one embodiment of the present invention, the present invention provides a cooking appliance, including: a shell 1, a heating container 2, a coil 3, a drive assembly 4, and a support member 5.

[0056] Specifically, the heating container 2 is disposed in the housing 1; the coil 3 is movably disposed in the housing 1, and a coil is wound on the coil 3. When the coil on the coil 3 is energized, it generates a magnetic field that causes the heating container 2 to heat up; the driving assembly 4 includes a driving part 40 and a moving part 42. The driving part 40 is connected to the moving part 42, and the moving part 42 is in contact with the coil 3. The driving part 40 drives the coil 3 to move relative to the heating container 2 through the moving part 42, so as to adjust the heating power of the cooking appliance during the cooking process; the support member 5 is disposed in the housing 1, and the moving part 42 is supported on the support member 5 and can move relative to the support member 5.

[0057] The cooking appliance provided by this utility model includes a shell 1, a heating container 2, a coil 3, a support 5, and a drive assembly 4. The heating container 2 and the coil 3 are both located on the shell 1. A coil is wound on the coil 3. When the coil on the coil 3 is energized, it generates a magnetic field. The heating container 2 heats up under the influence of this magnetic field, thus cooking the food inside. The drive assembly 4 includes a drive part 40 and a moving part 42. The drive part 40 drives the moving part 42 to move. The moving part 42 contacts the coil 3, causing it to move relative to the heating container 2. This movement of the magnetic field generated by the coil on the coil 3 relative to the heating container 2 changes the intensity of the induced magnetic field in the heating container 2. During the cooking process, the coupling between the coil 3 and the heating container 2 is adjusted, allowing for variations in the heating power of the appliance. This variation in heating power enables a smooth temperature transition, reducing temperature fluctuations and improving the cooking effect. Meanwhile, the moving part 42 is supported by the support member 5 and can move relative to the support member 5. The support member 5 provides support for the moving part 42, reducing the impact of the moving part 42's own weight on power transmission. At the same time, the moving part 42 is supported by the support member 5, which also ensures the reliability of the position of the moving part 42, thereby ensuring the stability of the contact between the moving part 42 and the coil disk 3, and improving the reliability of the movement of the coil disk 3.

[0058] It should be noted that the movement of the coil 3 relative to the heating container 2 can adjust the distance between at least a part of the coil 3 and the heating container 2, thereby adjusting the power of the heating container 2. Specifically, the movement of the coil 3 can be lifting or lowering relative to the heating container 2 to move closer to or further away from the heating container 2, or it can be flipping or shaking relative to the heating container 2 to change the distance between at least a part of the coil 3 and the heating container 2, or it can be translating relative to the heating container 2 to adjust the positional relationship between the coil on the coil 3 and the heating container 2.

[0059] It is understandable that the position of the drive coil 3 relative to the heating container 2 changes gradually during the movement of the drive component 4, thus enabling the heating power of the heating container 2 to change gradually. In other words, through the movement of the coil 3, the heating power of the heating container 2 can be infinitely adjusted, increasing the adjustable range of the heating power of the heating container 2. Consequently, during the cooking process, the heating power of the cooking appliance can be smoothly adjusted, reducing temperature fluctuations and improving the cooking effect of the food.

[0060] Optionally, during the cooking process, the heating power required for each cooking stage is different. By moving the coil 3 relative to the heating container 2, the temperature between each cooking stage can be smoothly transitioned during continuous heating, thereby improving the cooking effect of the ingredients.

[0061] Optionally, the heating container 2 includes a magnetic pot or a pot body with a magnetic layer.

[0062] Optionally, the drive component 4 can drive the coil disk 3 to stop at any position within the movable range or drive the coil disk 3 to reciprocate within the movable range, thereby achieving stepless adjustment of the heating power.

[0063] like Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, optionally, the coil disk 3 is disposed at least opposite to the bottom wall of the heating container 2, the moving part 42 is located on the side of the coil disk 3 away from the heating container 2, the moving part 42 is provided with a first mating part 420, the coil disk 3 is provided with a second mating part 30, and the first mating part 420 and the second mating part 30 are in contact; the driving part 40 drives the moving part 42 to rotate, so as to drive the coil disk 3 to rise and fall between a first position close to the heating container 2 and a second position away from the heating container 2 through the first mating part 420 and the second mating part 30.

[0064] In this embodiment, the coil 3 is positioned at least opposite to the bottom wall of the heating container 2. When the coil on the coil 3 is energized, the bottom wall of the heating container 2 will heat up, thereby cooking the food inside the heating container 2. The moving part 42 is located on the side of the coil 3 away from the heating container 2, and a first mating part 420 is provided on the moving part 42. A second mating part 30 is provided on the coil 3. When the driving part 40 drives the moving part 42 to rotate, the first mating part 420 rotates with the moving part 42. Since the first mating part 420 and the second mating part 30 are in contact, the coil 3 is raised and lowered by the cooperation of the first mating part 420 and the second mating part 30. This causes the coil 3 to rise and fall between a first position close to the heating container 2 and a second position far away from the heating container 2, thereby changing the distance between the coil 3 and the heating container 2. During the cooking process, the coupling between the coil 3 and the heating container 2 is adjusted, thereby adjusting the heating power of the cooking appliance.

[0065] Optionally, the lifting of the coil 3 can be a linear movement along the vertical direction, or a swaying lifting, a spiral lifting, or a lifting at a certain angle to the vertical direction.

[0066] Optionally, the vertical direction is the direction of the axis of rotation of the moving part 42.

[0067] In some embodiments, the distance between the first position and the second position may be greater than 0 mm and less than or equal to 100 mm.

[0068] In this embodiment, the lifting range of the coil 3 is set to be greater than 0 mm and less than or equal to 100 mm, which can reduce the impact of the lifting of the coil 3 on the overall height of the cooking appliance, and also ensure the adjustable range of heating power.

[0069] In practical applications, the distance between the first position and the second position is any value among 5mm, 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm, 65mm, 70mm, 75mm, 80mm, 85mm, 90mm, 95mm, and 100mm, or any value between any two values.

[0070] Optionally, the drive assembly 4 is used to drive the coil disk 3 to reciprocate between the first position and the second position, or to drive the coil disk 3 to move to any position between the first position and the second position.

[0071] like Figure 3 and Figure 6As shown, in some embodiments, optionally, along the axis of rotation of the moving part 42, the support member 5 is provided with a plurality of support ribs 50 on the side facing the moving part 42, and the support member 5 contacts the moving part 42 through the support ribs 50.

[0072] In this embodiment, the support member 5 is provided with a support rib 50. The support member 5 contacts the moving part 42 through the support rib 50, which reduces the contact area between the support member 5 and the moving part 42. As a result, when the moving part 42 moves relative to the support member 5, the wear on the moving part 42 is reduced, as well as the frictional resistance and frictional noise of the rotation of the moving part 42 are also reduced.

[0073] In some embodiments, optionally, a plurality of support ribs 50 are spaced apart about the axis of rotation of the moving part 42; and / or any support rib 50 is strip-shaped and extends radially along the moving part 42; or any support rib 50 includes a plurality of protrusions, the plurality of protrusions being spaced apart radially along the moving part 42.

[0074] In this embodiment, multiple support ribs 50 are spaced apart around the rotation axis to reliably support the moving part 42 and prevent it from tilting. Optionally, the support member 5 is strip-shaped and extends radially along the moving part 42, so that the support ribs 50 can reliably support the moving part 42 while reducing the contact area with the moving part 42, thereby reducing wear on the moving part 42. Optionally, any support rib 50 includes multiple radially spaced protrusions, further reducing the contact area between the support rib 50 and the moving part 42, thus increasing the service life of the moving part 42.

[0075] like Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, optionally, one of the support member 5 and the moving part 42 is provided with a limiting post 52, and the other of the support member 5 and the moving part 42 is sleeved on the limiting post 52 and can rotate relative to the limiting post 52.

[0076] In this embodiment, one of the support member 5 and the moving part 42 is provided with a limiting post 52, and the other is sleeved on the limiting post 52 to achieve rotational connection and radial limiting, which ensures the relative position between the moving part 42 and the support member 5, thereby ensuring the reliability of the driving of the coil disk 3 by the moving part 42.

[0077] Alternatively, the other of the support member 5 and the moving part 42 may be clearance-fitted with the limiting post 52.

[0078] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, in some embodiments, the cooking appliance may optionally include: a support base 6 disposed inside the housing 1, a heating container 2 mounted on the support base 6, a coil 3 disposed on the outside of the support base 6 and disposed opposite to the bottom of the support base 6; a support member 5 connected to the support base 6 or the support member 5 connected to the housing 1, and a moving part 42 located between the support member 5 and the support base 6.

[0079] In this embodiment, the cooking appliance also includes a support base 6, which is disposed inside the housing 1 and supports the heating container 2. A coil 3 is located outside the support base 6 and is positioned opposite the bottom of the support base 6, allowing the coil 3 to rise and fall relative to the heating container 2 at the bottom of the support base 6, thereby adjusting the heating power of the cooking appliance. The support member 5 is connected to the support base 6, ensuring reliable installation of the support member 5 and guaranteeing the reliable support of the support base 6 for the moving part 42. This also allows the support member 5 and the support base 6 to be integrated, improving the integration of internal components and facilitating assembly. Alternatively, the support member 5 can be connected to the housing 1 to facilitate repair or replacement of individual components when the support member 5 is severely worn.

[0080] like Figure 6 As shown, in some embodiments, the support member 5 may optionally include: a cover 54, which covers the moving part 42 along the axis of rotation of the moving part 42, and the cover 54 is disposed on the side of the moving part 42 away from the coil disk 3; and a connecting part 56, which is disposed on the outer side wall of the cover 54 and is connected to the support base 6.

[0081] In this embodiment, the support member 5 includes a cover 54 and a connecting part 56. The cover 54 covers the moving part 42 to protect the moving part 42. The connecting part 56 is connected to the support base 6 to fix the support member 5 to the support base 6.

[0082] Optionally, the connecting part 56 is provided on the outer side wall of the cover 54 and is an integral structure with the cover 54.

[0083] Optionally, the connecting part 56 includes a connecting post, and the support base 6 is provided with a mounting hole. The connecting post passes through the mounting hole to realize the connection between the support member 5 and the support base 6.

[0084] like Figure 1 and Figure 7 As shown, in some embodiments, optionally, the support base 6 is provided with a first limiting part 60, and the coil disk 3 is provided with a second limiting part 32. The first limiting part 60 and the second limiting part 32 are slidably connected along the axial direction of the moving part 42.

[0085] In this embodiment, a first limiting part 60 is provided on the support base 6, and a second limiting part 32 is provided on the coil disk 3. The first limiting part 60 and the second limiting part 32 are slidably connected, which realizes the lifting and lowering of the coil disk 3 along a predetermined trajectory, which can prevent the radial position of the coil disk 3 from shifting and ensure the reliability of the movement position of the coil disk 3.

[0086] Optionally, the coil 3 can be raised and lowered along the vertical direction of the cooking appliance.

[0087] Optionally, the coil disk 3 moves up and down along the axis of rotation of the moving part 42.

[0088] Optionally, one of the first limiting part 60 and the second limiting part 32 is a slider, and the other is a groove.

[0089] Optionally, there are multiple first limiting parts 60 and multiple second limiting parts 32, with multiple first limiting parts 60 spaced apart along the rotation direction and multiple second limiting parts 32 spaced apart along the rotation direction.

[0090] Optionally, the coil disk 3 has a through hole in the middle and the support base 6 has a limiting post at the bottom. The limiting post is sleeved in the through hole to limit the position of the coil disk 3.

[0091] In some embodiments, optionally, a coil is wound around the outer wall of the support 6, and the coil on the support 6 can surround the heating container 2. When the coil on the support 6 is energized, it can generate a magnetic field to heat the heating container 2.

[0092] In this embodiment, a coil is wound on the support base 6, and the coil on the support base 6 surrounds the heating container 2. When the coil on the support base 6 is energized, the heating container 2 can be heated. That is, both the coil on the coil disk 3 and the coil on the support base 6 can heat the heating container 2. Optionally, the coil on the coil disk 3 and the coil on the support base 6 can heat the heating container 2 simultaneously, or the coil on the coil disk 3 and the coil on the support base 6 can heat the heating container 2 separately.

[0093] Optionally, the coil on the support 6 is wound around the outer wall of the support 6.

[0094] Optionally, the bottom wall of the support base 6 is also provided with a viewing window, which is arranged opposite to at least a portion of the coil disk 3 so that the user can observe the position of the coil disk 3.

[0095] Optionally, at least one elastic element 9 is provided between the bottom wall of the support base 6 and the coil disk 3. The at least one elastic element 9 is in a compressed state so that the moving part 42 and the coil disk 3 can be reliably fitted together, thus ensuring the reliability of power transmission between the moving part 42 and the coil disk 3.

[0096] Optionally, when the drive unit 40 is turned on, the drive motion unit 42 rotates, and the coil disk 3 is raised to the first position through the first mating part 420 and the second mating part 30. When the coil disk 3 is lowered, the coil disk 3 is lowered to the second position under its own weight and the action of the elastic member 9. That is, the setting of the elastic member 9 can not only realize reliable contact between the coil disk 3 and the drive component 4, but also realize the reset of the coil disk 3, thereby ensuring the reliability of the mechanism.

[0097] In some embodiments, the drive unit 40 may be mounted on the support base 6 or on the housing 1.

[0098] In this embodiment, the drive unit 40 can be installed on the support base 6 or on the housing 1. When the drive unit 40 and the support member are installed on the support base 6, the support base 6, the support member 5 and the drive assembly 4 are assembled together, which improves the integrated design of the internal components of the cooking appliance, thereby facilitating the assembly of the internal components of the cooking appliance and the assembly of the whole machine.

[0099] Optionally, the drive unit 40 includes a motor. Optionally, the motor is fitted with a magnetic shield to prevent the components on the motor from overheating in the magnetic field, which could affect its lifespan or operating efficiency, or the motor includes a magnetic shielding structure.

[0100] like Figure 1 and Figure 8 As shown, in some embodiments, the cooking appliance may optionally include: a first detection component 70, disposed on the support 5 or the housing 1; and a second detection component 72, disposed on the moving part 42, wherein the first detection component 70 determines the position of the coil 3 based on the second detection component 72.

[0101] In this embodiment, to prevent abnormal lifting and lowering of the coil 3, it is necessary to detect, limit, and provide feedback on the vertical movement of the coil 3. Therefore, a first detection component 70 is provided on the support member 5 or the housing 1, and a second detection component 72 is provided on the moving part 42. During the process of the moving part 42 driving the coil 3 to move relative to the heating container, the second detection component 72 and the first detection component 70 on the moving part 42 change position, thereby causing the detection parameters of the first detection component 70 to change. The position of the coil 3 is determined according to the detection parameters, thereby realizing the detection of the position of the coil 3 and ensuring the normal operation of the mechanism.

[0102] In some embodiments, the first detection component 70 may optionally include at least one of the following: a micro switch, a reed switch, and a grating; the second detection component 72 may include a magnet.

[0103] In this embodiment, the first detection component 70 can be a position detection structure such as a micro switch, a reed switch, and a grating, and the second detection component 72 includes a magnet. During the rotation of the moving part 42, the magnet rotates with the moving part 42, thereby changing the magnetic field of the magnet at the location of the first detection component 70, so as to realize the position detection during the movement of the coil disk 3.

[0104] Specifically, a magnet is mounted on the moving part 42, and its circumferential position changes as the moving part 42 rotates; a reed switch is mounted on the support 5, and its position remains fixed; when the moving part 42 rotates and drives the magnet to approach or move away from the reed switch, it causes the signal inside the reed switch to change on and off, and feeds back to the control board; by adjusting the relative position of the reed switch and the magnet, the position of the coil disk 3 is controlled.

[0105] Optionally, the first detection component 70 and the second detection component 72 can be corresponding equal numbers of reed switches and magnets, or one type of device can be more numerous than the other, as long as it can achieve position change detection.

[0106] Optionally, the first detection component 70 is located on the side of the support 5 opposite to the moving part 42.

[0107] like Figure 4 , Figure 5 and Figure 7 As shown, in some embodiments, optionally, the moving part 42 includes: a first gear 422 located at the bottom of the coil disk 3, the first gear 422 having a first mating part 420, the side of the first gear 422 facing away from the coil disk 3 being supported by the support member 5; and a second gear 424 connected to the driving part 40, located on one radial side of the first gear 422 and meshing with the first gear 422, the driving part 40 driving the first gear 422 to rotate through the second gear 424.

[0108] In this embodiment, the moving part 42 includes a first gear 422 and a second gear 424. The second gear 424 is connected to the driving part 40 and is located on one radial side of the first gear 422, meshing with it. The first gear 422 has a first mating part 420, and the coil disk 3 has a second mating part 30. The first mating part 420 and the second mating part 30 are in contact. When the driving part 40 drives the second gear 424 to rotate, the meshing of the first gear 422 and the second gear 424 causes the first gear 422 to rotate, which in turn causes the first mating part 420 to rotate relative to the second mating part 30, thus raising and lowering the second mating part 30, and consequently raising and lowering the coil disk 3. The cooking appliance proposed in this application realizes the conversion of power from rotation to linear lifting through the transmission of the first gear 422 and the second gear 424 and the cooperation of the first mating part 420 and the second mating part 30, thereby improving the stability of power transmission. At the same time, the second gear 424 is located on one side of the first gear 422, which can also reduce the axial space occupied, thereby reducing the overall height of the cooking appliance.

[0109] Optionally, a magnet is mounted on the first gear 422, and its circumferential position changes as the first gear 422 rotates; a reed switch is mounted on the support 5, and its position remains fixed; when the first gear 422 rotates and drives the magnet to approach or move away from the reed switch, it causes the signal inside the reed switch to change on and off, and feeds back to the control board; by adjusting the relative position of the reed switch and the magnet, the position of the coil disk 3 is controlled.

[0110] like Figure 7 As shown, in some embodiments, optionally, one of the first mating portion 420 and the second mating portion 30 includes a first protrusion 4200 and a first recess 4202, the first protrusion 4200 and the first recess 4202 are alternately arranged along the rotation direction of the first gear 422, and the other of the first mating portion 420 and the second mating portion 30 can alternately engage with the first protrusion 4200 and the first recess 4202 to make the coil disk 3 rise and fall between the first position and the second position.

[0111] In this embodiment, the first mating part 420 and the second mating part 30 achieve switching from rotation to linear movement through a concave-convex structure. One of the first mating parts 420 and 30 includes a first protrusion 4200 and a first concave part 4202. As the first mating part 420 rotates with the first gear 422, the other of the first mating part 420 and the other of the second mating part 30 alternately passes through the first protrusion 4200 and the first concave part 4202, thereby realizing the reciprocating lifting and lowering of the coil 3. When the other of the first mating part 420 and the other of the second mating part 30 engages with the first protrusion 4200, the first mating part 420 and the other of the second mating part 30 together lift the coil 3, bringing it closer to the heating container 2. When the other of the first mating part 420 and the other of the second mating part 30 engages with the first concave part 4202, the coil 3 descends, moving it away from the heating container 2.

[0112] Optionally, one of the first mating part 420 and the second mating part 30 includes an inclined structure, and the other can move on the inclined structure as the moving part 42 rotates to realize the lifting and lowering of the coil disk 3.

[0113] Optionally, one of the first mating part 420 and the second mating part 30 includes an inclined structure, and the other may include a support rod. The support rod can slide on the inclined structure as the moving part 42 rotates, thereby realizing the lifting and lowering of the coil disk 3.

[0114] like Figure 7 As shown, in some embodiments, optionally, the other of the first mating portion 420 and the second mating portion 30 further includes a second protrusion 300 and a second recess 302, the second protrusion 300 and the second recess 302 being alternately arranged along the rotation direction of the first gear 422.

[0115] In this embodiment, the other of the first mating part 420 and the second mating part 30 further includes a second protrusion 300 and a second recess 302. The second protrusion 300 and the second recess 302 are alternately arranged along the rotation direction of the first gear 422. Thus, the second protrusion 300 and the second recess 302 alternately engage with the first protrusion 4200 and the first recess 4202, increasing the lifting range of the coil 3, thereby increasing the adjustable range of the heating power of the cooking appliance and improving the stability of the drive between the coil 3 and the first gear 422.

[0116] Optionally, along the axial direction of the first gear 422, when the first protrusion 4200 contacts the second protrusion 300, the coil disk 3 is located in the first position; when the second recess 302 contacts the first protrusion 4200 and the second protrusion 300 contacts the first recess 4202, the coil disk 3 is located in the second position.

[0117] In some embodiments, optionally, the first protrusion 4200 and the first recess 4202 are connected sequentially along the rotation direction, or the first protrusion 4200 and the first recess 4202 are spaced apart along the rotation direction; and / or the second protrusion 300 and the second recess 302 are connected sequentially along the rotation direction, or the second protrusion 300 and the second recess 302 are spaced apart along the rotation direction; and / or the second mating part 30 is located in the middle of the coil disk 3, the coil on the coil disk 3 is located around the second mating part 30, or the second mating part 30 is arranged radially along the first gear 422 close to the side wall of the coil disk 3, and the second mating part 30 surrounds the coil on the coil disk 3.

[0118] In this embodiment, the first protrusion 4200 and the first recess 4202 are sequentially connected along the rotation direction of the first gear 422. This makes the movement of the coil 3 smoother during the rotation of the moving part 42, and allows the coil 3 to continuously rise and fall with the continuous rotation of the first gear 422. This results in a continuous change in the induced magnetic field of the heating container 2, increasing the adjustable range of heating power during cooking. Alternatively, the first protrusion 4200 and the first recess 4202 can be spaced apart along the rotation direction, making the rising and falling of the coil 3 non-continuous, achieving intermittent rising and falling of the coil 3. Correspondingly, the second protrusion 300 and the second recess 302 can also be sequentially connected or intermittently arranged. Optionally, the second mating part 30 can be located in the middle of the coil 3 to increase the winding area of ​​the coil; the second mating part 30 can also be located radially outward of the coil 3 to increase the reliability and stability of the transmission.

[0119] Optionally, the rotation direction of the first gear 422 can be Figure 7 The direction indicated by the middle arrow can also be... Figure 7 The opposite direction indicated by the middle arrow.

[0120] like Figure 4 As shown, in some embodiments, the cooking appliance may optionally include a rolling element 8 disposed in at least one of the first mating portion 420 and the second mating portion 30, the first mating portion 420 and the second mating portion 30 being in contact through the rolling element 8.

[0121] In this embodiment, the cooking appliance also includes a rolling element 8. The first mating part 420 and the second mating part 30 contact each other through the rolling element 8, so that the sliding friction between the first mating part 420 and the second mating part 30 is converted into rolling friction, thereby reducing the frictional resistance between the first mating part 420 and the second mating part 30.

[0122] Optionally, one of the first mating part 420 and the second mating part 30 is provided with a groove 4204, a part of the rolling element 8 is embedded in the groove 4204 and can roll in the groove 4204, and another part protrudes out of the groove 4204 and contacts the other of the first mating part 420 and the second mating part 30.

[0123] Optionally, the rolling element 8 may be any one of a metal element, a silicone element, or a rubber element.

[0124] Optionally, the cooking appliance is an electromagnetic heating appliance, specifically including rice cookers, electric pressure cookers, electric slow cookers, etc.

[0125] According to some embodiments of this application, optionally, during the horizontal rotation of the large gear (e.g., the first gear 422), it meshes with the small gear (e.g., the second gear 424). In order to ensure stable meshing, the position of the large gear needs to be limited.

[0126] In this system, the large gear, due to its large size and weight, cannot move in mid-air. It is mounted on a gear cover (e.g., support 5), and the two can be locally supported by means of line contact, such as by setting support ribs 50. In this way, the large gear is only subjected to the horizontal force between the teeth, while it is not subjected to the vertical force, which is beneficial for horizontal movement.

[0127] The large gear needs to be circumferentially limited to ensure effective meshing with the small gear teeth. The gap between the center of the large gear and the gear cover is small, which reduces the wobble of the large gear.

[0128] A detection component (such as the first detection assembly 70) is mounted on the gear cover to detect the position. This component can be a microswitch, reed switch, optical grating, or other position detection mechanism. The detection mechanism can also be mounted on other nearby parts. The travel distance of the lifting plate needs to be detected.

[0129] The cooking appliance proposed in this application features a coil plate 3 that can be raised and lowered, and its position during the raising and lowering process can be detected and feedback provided. To address the issue of a large rotating mechanism, a mounting cover is designed to provide support and limit its movement.
