Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and more specifically, to a cooking utensil. Background Technology

[0002] Currently, in electromagnetic heating cooking appliances, the food inside the inner pot is heated by the magnetic field between the coil and the inner pot. However, in these technologies, the position of the coil relative to the inner pot is fixed, and the heating power can only be controlled by turning the coil on and off. This results in large temperature fluctuations of the food inside the inner pot during cooking, which is not conducive to improving cooking results. Furthermore, in these technologies, users cannot directly observe the state of the coil. Utility Model Content

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

[0004] Therefore, this utility model provides a cooking utensil.

[0005] In view of this, the present invention proposes a cooking appliance, comprising: a shell; a support base disposed within the shell, the bottom wall of the support base having an opening; a heating container capable of being installed on the support base; a coil disc disposed opposite to the opening, a coil being wound on the coil disc, the coil on the coil disc generating a magnetic field when energized to heat the heating container; and a driving component connected to the coil disc for driving the coil disc to move relative to the heating container, thereby adjusting the heating power of the cooking appliance during the cooking process.

[0006] The cooking appliance provided by this utility model includes a shell, a support base, a heating container, and a coil. The support base is disposed inside the shell and is used to support the heating container. A coil is wound on the coil. When the coil on the coil is energized, it generates a magnetic field. The heating container heats up under the influence of the magnetic field of the coil, thus cooking the food inside the heating container. A drive component is connected to the coil and can drive the coil to move relative to the heating container. This movement of the magnetic field generated by the coil relative to the heating container causes a change in the intensity of the induced magnetic field in the heating container. Consequently, the heating power of the cooking appliance changes during the cooking process. This allows for a smooth temperature transition during cooking, reducing temperature fluctuations and improving the cooking effect. Meanwhile, the bottom wall of the support base is provided with an opening, and the coil is arranged opposite to the opening. On the one hand, when the heating container is removed, the user can intuitively observe the state of the coil, realizing the visualization of the coil. On the other hand, there is no obstruction between the coil and the heating container, which can reduce the overall height of the cooking appliance and realize the miniaturization design of the cooking appliance. Furthermore, this arrangement means that there are no other components blocking the coil and the heating container, resulting in higher heating efficiency. Moreover, changes in the relative position between the coil and the heating container are more likely to cause changes in electromagnetic parameters. In other words, the cooking appliance proposed in this application can meet a large range of electromagnetic parameter changes with a small lifting space.

[0007] The cooking appliance provided by this utility model may also have the following additional technical features:

[0008] In some embodiments, the drive assembly can optionally drive the coil disc to extend from the port into the support.

[0009] In this embodiment, the drive assembly can drive the coil to extend into the support base through the opening. That is, during the process of the drive assembly driving the coil to move in order to adjust the heating power, the coil can move into the support base. In other words, the movement of the coil relative to the heating container can be achieved using the space inside the support base, thereby reducing the space occupied in the height direction caused by setting the coil and lowering the overall height of the cooking appliance.

[0010] In some embodiments, the cooking appliance may optionally include: an enclosure connected to a support base, the enclosure surrounding the periphery of the opening, a coil at least partially housed within the enclosure and movable relative to the enclosure, and a gap between the coil and the sidewall of the enclosure.

[0011] In this embodiment, the cooking appliance also includes an enclosure, which is connected to the support base and surrounds the periphery of the opening. The coil is at least partially disposed within the enclosure, providing protection for the coil and ensuring the reliability of its movement. Simultaneously, a gap exists between the coil and the sidewall of the enclosure, preventing direct contact and reducing resistance and friction during the coil's movement relative to the heating container. This reduces wear on both the coil and the enclosure, extending their service life.

[0012] In some embodiments, the width of the gap may be greater than 0 mm and less than or equal to 60 mm.

[0013] In this embodiment, the width of the gap is set between 0mm and 60mm, which ensures the relative movement between the coil and the enclosure while preventing the gap from being too large and causing debris to enter.

[0014] In some embodiments, the cooking appliance may optionally include a shield connected to the coil and / or enclosure, the shield being located at the gap.

[0015] In this embodiment, the cooking appliance also includes a shielding member connected to the coil and / or the enclosure and located at the gap, thereby shielding the gap and preventing debris from falling into the bottom wall of the enclosure and affecting the movement of the coil.

[0016] In some embodiments, the shielding member may optionally include: a flexible body surrounding the periphery of the coil disk; and a connecting portion disposed on one side of the flexible body, wherein the coil disk is connected to the connecting portion.

[0017] In this embodiment, the shielding component includes a flexible body with a connecting portion on one side. The coil disk is connected to the connecting portion, so that the shielding component is reliably installed on the coil disk. At the same time, the flexible body surrounds the periphery of the coil disk, thereby achieving shielding of the gap around the coil disk and improving the shielding effect of debris.

[0018] In some embodiments, optionally, one of the coil and the connecting portion includes a groove, and the other is inserted into the groove and press-fitted with the groove.

[0019] In this embodiment, the coil disk and the connecting part are interference-fitted by a groove, so that the shielding part is securely fitted on the coil disk, preventing the shielding part from falling off.

[0020] In some embodiments, the shielding member may optionally include a protrusion disposed on the other side of the flexible body, wherein the flexible body contacts or is spaced apart from the sidewall of the enclosure via the protrusion.

[0021] In this embodiment, a protrusion is provided on the other side of the flexible body. The flexible body contacts or is spaced apart from the side wall of the enclosure through the protrusion, further reducing the gap between the flexible body and the side wall of the enclosure, effectively preventing debris from entering the gap. At the same time, when the flexible body contacts the side wall of the enclosure through the protrusion, the contact area between the flexible body and the side wall of the enclosure is reduced, thereby reducing the friction and resistance during the movement of the coil.

[0022] In some embodiments, the shielding member may optionally include a telescopic member, one end of which is connected to the side wall of the enclosure and the other end of which is connected to the coil disk. During the movement of the coil disk relative to the support base, the telescopic member can extend and retract with the movement of the coil disk.

[0023] In this embodiment, the shielding member can also be a telescopic member. One end of the telescopic member is connected to the storage compartment of the enclosure, and the other end is connected to the coil disc, so that the telescopic member shields the gap and prevents debris from falling into the bottom of the enclosure through the gap. At the same time, the telescopic member can extend and retract during the movement of the coil disc relative to the support base, thereby avoiding obstruction of the movement of the coil disc.

[0024] In some embodiments, the stretchable element may optionally include an elastic structural element or a corrugated structural element.

[0025] In this embodiment, the telescopic component includes an elastic structural component or a corrugated structural component. The elastic structural component can extend and retract under tension or compression. The corrugated structural component is corrugated, which allows it to fold or unfold with the movement of the coil.

[0026] In some embodiments, optionally, when the cooking appliance includes an enclosure, a support wall is provided at the end of the enclosure away from the opening, the support wall is disposed opposite to the opening and the support wall is provided with a through hole, and the drive assembly is located on the side of the support wall away from the heating container, wherein a portion of the coil extends out of the through hole to the outside of the enclosure and contacts the drive assembly, or a portion of the drive assembly extends into the enclosure through the through hole and contacts the coil.

[0027] In this embodiment, the bottom of the enclosure is sealed by a support wall, and the support wall has a through hole, allowing the coil to engage with the drive assembly. Either a portion of the coil extends out of the through hole to the outside of the enclosure and engages with the drive assembly, or a portion of the drive assembly extends into the enclosure through the through hole and engages with the coil. In the cooking appliance proposed in this application, the support wall supports the coil when not in operation, improving its stability and reducing pressure on the moving parts. Simultaneously, the support wall prevents food residue or liquid from falling into the bottom of the casing, thus avoiding cleaning difficulties or damage to electrical components.

[0028] In some embodiments, the support base, enclosure, and support wall may be an integral structure.

[0029] In this embodiment, the support base, the enclosure, and the support wall are an integral structure, which improves the connection strength between the three and reduces the assembly difficulty.

[0030] Optionally, the support base, enclosure, and support wall are integrally molded structures.

[0031] In some embodiments, the support may optionally include an opening, a passage disposed opposite to the opening, and the coil disk exposed in the opening along the circumference of the coil disk.

[0032] In this embodiment, the support base includes an opening through which the heating container can be placed. The coil can be exposed through the opening, so that even when the heating container is not placed in the support base, the user can observe the maximum outline of the coil, thus making the movement mode and position of the coil intuitively displayed to the user.

[0033] In some embodiments, the drive assembly may optionally include: a drive unit; a motion unit connected to the drive unit, the motion unit having a first mating part, and the coil disk having a second mating part, the first mating part contacting the second mating part; wherein the drive unit is capable of driving the motion unit to rotate, and the first mating part rotating relative to the second mating part, so as to raise and lower the coil disk.

[0034] In this embodiment, the driving component includes a driving part and a moving part. The driving part is provided with a first mating part, and the moving part is provided with a second mating part. The first mating part and the second mating part are in contact. During the process of the driving part driving the moving part to rotate, the coil disk is raised and lowered relative to the heating container through the cooperation of the first mating part and the second mating part. This allows the distance between the coil disk and the heating container to be adjusted, making the range of changes in the induced magnetic field of the heating container larger and increasing the adjustable range of the heating power.

[0035] 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 moving portion, 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 move between near the heating container and away from the heating container.

[0036] In this embodiment, the first mating part and the second mating part achieve the switching between rotation 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 moving part, 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 first 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.

[0037] In some embodiments, optionally, the other of the first mating portion and the second mating portion includes a support leg; the support leg is capable of contacting the first protrusion and the first recess in sequence to raise and lower the coil.

[0038] In this embodiment, one of the first mating part and the second mating part includes a first protrusion and a first concave part, and the other includes a support leg. During the process of the driving part driving the moving part to rotate, the support leg passes through the first protrusion and the first concave part in sequence, so that the support leg moves up and down along the axis of rotation of the moving part, thereby realizing the lifting and lowering of the coil disc.

[0039] In some embodiments, the end of the support leg is provided with a protrusion, and the support leg contacts the first protrusion and the first recess through the protrusion.

[0040] In this embodiment, the support foot contacts the first protrusion or the first recess through a protrusion, which reduces the contact area between the support foot and the first protrusion or the first recess, thereby reducing the wear of the support foot and improving its service life.

[0041] In some embodiments, the driving part may optionally include a drive motor; the moving part includes a first gear and a second gear, the second gear being connected to the drive motor, a first mating part being disposed on the first gear, the first gear meshing with the second gear; or the moving part includes a turntable, the first mating part being disposed on the side of the turntable facing the coil disk, and the drive motor being disposed in the middle of the turntable to drive the turntable to rotate.

[0042] In this embodiment, the driving unit includes a drive motor, and the moving unit includes a first gear and a second gear. The drive motor is connected to the second gear, and the first gear meshes with the second gear. The drive motor drives the first gear to rotate through the second gear. This allows the drive motor to be placed around the first gear, reducing the overall height of the cooking appliance. The cooking appliance proposed in this application achieves the lifting and lowering of the coil through the rotation of the drive motor and gear structure, making the lifting and lowering of the coil more stable and reliable. Simultaneously, converting rotation into lifting motion also reduces the space occupied by the drive components in the height direction. Alternatively, the moving unit includes a turntable, with a first mating part located on the side of the turntable near the coil. The drive motor is connected to the center of the turntable, allowing the drive motor to directly drive the turntable to rotate, reducing the number of transmission components.

[0043] In some embodiments, optionally, when the moving part includes a first gear and a second gear, the first gear has an annular structure, and the first mating part is disposed on the inner sidewall of the first gear and is arranged in an annular shape.

[0044] In this embodiment, when the moving part includes a first gear and a second gear, the first gear has an annular structure, that is, the inside of the first gear is hollow, the teeth of the first gear are arranged on the outer periphery of the first gear, and the first mating part is arranged in an annular shape in the hollow part inside the first gear, which greatly reduces the weight of the first gear, thereby helping to reduce the driving energy consumption of the drive part.

[0045] In some embodiments, the coil can optionally be raised and lowered between a first position close to the heating container and a second position far from the heating container, wherein the distance between the first and second positions is greater than 0 mm and less than or equal to 100 mm.

[0046] In this embodiment, the lifting range of the coil 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 on the overall height of the cooking appliance, while ensuring the adjustable range of heating power.

[0047] In some embodiments, the driving component is optionally used to drive the coil disk to reciprocate between a first position and a second position, or to drive the coil disk to move to any position between the first position and the second position.

[0048] In this embodiment, during cooking, the driving component drives the coil to move, allowing it to reciprocate between near and away from the heating container. This continuously changes the heating power of the cooking appliance, causing the food inside the heating container to tumble and stir, thus improving the cooking effect. Alternatively, the driving component can control the coil to move to any position between a first and a second position according to different cooking stages, making the heating power infinitely adjustable.

[0049] In some embodiments, optionally, a coil is wound on 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.

[0050] 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.

[0067] 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.

[0068] 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.

[0069] The following reference Figures 1 to 12 This invention describes a cooking appliance proposed according to some embodiments of the present invention.

[0070] like Figure 1 , Figure 2 , Figure 6 , Figure 9 and Figure 10As shown, according to one embodiment of the present invention, a cooking appliance is provided, comprising: a housing 1; a support base 2 disposed inside the housing 1, the bottom wall of the support base 2 having an opening 22; a heating container 8 capable of being installed on the support base 2; a coil 3 disposed opposite to the opening 22, a coil wound on the coil 3, the coil on the coil 3 generating a magnetic field when energized to heat the heating container 8; and a driving component 4 connected to the coil 3 for driving the coil 3 to move relative to the heating container 8, so as to adjust the heating power of the cooking appliance during the cooking process.

[0071] The cooking appliance provided by this utility model includes a shell 1, a support base 2, a heating container 8, and a coil 3. The support base 2 is disposed inside the shell 1 to support the heating container 8. A coil is wound on the coil 3. When the coil on the coil 3 is energized, the coil on the coil 3 can generate a magnetic field. The heating container 8 heats up under the action of the magnetic field of the coil, thus cooking the food inside the heating container 8. A driving component 4 is connected to the coil 3 and can drive the coil 3 to move relative to the heating container 8. This movement of the magnetic field generated by the coil on the coil 3 relative to the heating container 8 causes a change in the intensity of the induced magnetic field in the heating container 8. Consequently, the heating power of the cooking appliance changes during the cooking process. This allows for a smooth temperature transition during cooking by changing the heating power, reducing temperature fluctuations and improving the cooking effect. Meanwhile, the bottom wall of the support base 2 is provided with an opening 22, and the coil 3 is arranged opposite to the opening 22. On the one hand, when the heating container 8 is removed, the user can intuitively observe the state of the coil 3, realizing the visualization of the coil 3. On the other hand, there is no obstruction between the coil 3 and the heating container 8, which can reduce the overall height of the cooking appliance and realize the miniaturization design of the cooking appliance. Furthermore, this arrangement means that there are no other components blocking the coil 3 and the heating container 8, resulting in higher heating efficiency. Moreover, the relative position change between the coil 3 and the heating container 8 is more likely to cause changes in electromagnetic parameters. That is, the cooking appliance proposed in this application can meet a large range of electromagnetic parameter changes with a small lifting space.

[0072] Optionally, the coil disk 3 can be disposed inside the support base 2 or outside the support base 2.

[0073] It is understandable that the position of the drive coil 3 relative to the heating container 8 changes gradually during the movement of the drive component 4, thus enabling the heating power of the cooking appliance to change gradually. In other words, the movement of the coil 3 allows the heating power of the cooking appliance to be infinitely adjustable, increasing the power adjustable range of the heating container 8. Consequently, during the cooking process, the heating power of the cooking appliance is smoothly adjusted, reducing temperature fluctuations and improving the cooking effect of the food.

[0074] It should be noted that the movement of the coil disk 3 relative to the heating container 8 can adjust the distance between at least a portion of the coil disk 3 and the heating container 8, thereby adjusting the power of the heating container 8. Specifically, the movement of the coil disk 3 can be lifting or lowering relative to the heating container 8 to move closer to or further away from the heating container 8, or it can be flipping or shaking relative to the heating container 8 to change the distance between at least a portion of the coil disk 3 and the heating container 8, or it can be translating relative to the heating container 8 to adjust the positional relationship between the coil on the coil disk 3 and the heating container 8.

[0075] Optionally, the heating container 8 includes a magnetic pot or a pot body with a magnetic layer.

[0076] It is understandable that different heating powers are required for each cooking stage. By moving the coil 3 relative to the heating container 8, the temperature can be smoothly transitioned between each cooking stage during continuous heating, thereby improving the cooking effect of the ingredients.

[0077] Optionally, the drive component 4 can drive the coil disk 3 to stop at any position within its movable range, thereby achieving stepless adjustment of the heating power.

[0078] In some embodiments, the drive assembly 4 can optionally drive the coil disk 3 to extend into the support base 2 through the port 22.

[0079] In this embodiment, the drive component 4 can drive the coil 3 to extend into the support base 2 through the port 22. That is, during the process of the drive component 4 driving the coil 3 to move to adjust the heating power, the coil 3 can move into the support base 2. In other words, the movement of the coil 3 relative to the heating container 8 can be realized by using the space inside the support base 2, thereby reducing the space occupied in the height direction caused by setting the coil 3 and reducing the overall height of the cooking appliance.

[0080] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, in some embodiments, the cooking appliance may optionally include: an enclosure 7 connected to the support 2, the enclosure 7 surrounding the periphery of the opening 22, the coil 3 being at least partially housed within the enclosure 7 and movable relative to the enclosure 7, and a gap 24 between the coil 3 and the side wall of the enclosure 7.

[0081] In this embodiment, the cooking appliance also includes an enclosure 7, which is connected to the support base 2 and surrounds the periphery of the opening 22. The coil 3 is at least partially disposed within the enclosure 7, providing protection for the coil 3 and ensuring the reliability of its movement. Simultaneously, a gap 24 exists between the coil 3 and the side wall of the enclosure 7, preventing direct contact between them. This reduces resistance and friction during the movement of the coil 3 relative to the heating container 8, thereby reducing wear on the coil 3 and the enclosure 7 and extending their service life.

[0082] like Figure 3 As shown, in some embodiments, optionally, the width H2 of the gap 24 is greater than 0 mm and less than or equal to 60 mm.

[0083] In this embodiment, the width H2 of the gap 24 is set between 0mm and 60mm, which ensures the relative movement between the coil 3 and the enclosure 7, and also prevents the gap between them from being too large, which could lead to the entry of foreign objects.

[0084] Optionally, the width H2 of the gap 24 between the coil disk 3 and the side wall of the enclosure 7 is any value among 5mm, 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 55mm, and 60mm, or any value between any two values.

[0085] like Figure 4 and Figure 5 As shown, in some embodiments, the cooking appliance may optionally include a shield 5 connected to the coil 3 and / or the enclosure 7, the shield 5 being located at the gap 24.

[0086] In this embodiment, the cooking appliance also includes a shielding member 5, which is connected to the coil 3 and / or the enclosure 7 and is located at the gap 24, thereby shielding the gap 24 and preventing debris from falling into the bottom wall of the enclosure 7 through the gap 24 and affecting the movement of the coil 3.

[0087] like Figure 4 and Figure 5 As shown, in some embodiments, optionally, the shielding member 5 includes: a flexible body 50 surrounding the periphery of the coil disk 3; and a connecting portion 52 disposed on one side of the flexible body 50, wherein the coil disk 3 is connected to the connecting portion 52.

[0088] In this embodiment, the shielding member 5 includes a flexible body 50, and a connecting part 52 is provided on one side of the flexible body 50. The coil disk 3 is connected to the connecting part 52, so that the shielding member 5 is reliably installed on the coil disk 3. At the same time, the flexible body 50 surrounds the periphery of the coil disk 3, thereby achieving the shielding of the circumferential gap 24 of the coil disk 3 and improving the shielding effect of debris.

[0089] like Figure 5 As shown, in some embodiments, optionally, one of the coil disk 3 and the connecting portion 52 includes a groove 520, and the other is inserted into the groove 520 and has an interference fit with the groove 520.

[0090] In this embodiment, the coil disk 3 and the connecting part 52 are interference-fitted by the groove 520, so that the shielding member 5 is securely fitted on the coil disk 3, preventing the shielding member 5 from falling off.

[0091] Optionally, the connecting part 52 includes a groove 520, the diameter of the circle containing the bottom wall of the groove 520 is smaller than the diameter of the coil disk 3, thereby making the shielding member 5 reliably fixed on the coil disk 3.

[0092] Optionally, the distance between the two opposite sidewalls of the groove 520 is less than the thickness of the portion of the coil disk 3 that mates with the groove 520.

[0093] like Figure 5 As shown, in some embodiments, optionally, the shielding member 5 further includes a protrusion 54, which is disposed on the other side of the flexible body 50, and the flexible body 50 is in contact with or spaced from the side wall of the enclosure portion 7 through the protrusion 54.

[0094] In this embodiment, a protrusion 54 is provided on the other side of the flexible body 50. The flexible body 50 contacts or is spaced from the side wall of the enclosure 7 through the protrusion 54, further reducing the gap 24 between the flexible body 50 and the side wall of the enclosure 7, effectively preventing debris from entering the gap 24. At the same time, when the flexible body 50 contacts the side wall of the enclosure 7 through the protrusion 54, the contact area between the flexible body 50 and the side wall of the enclosure 7 is reduced, thereby reducing the friction and resistance during the movement of the coil 3.

[0095] Optionally, the protrusions 54 are arranged in a ring around the periphery of the flexible body 50, or the protrusions 54 are spaced apart around the periphery of the flexible body 50.

[0096] like Figure 11 and Figure 12 As shown, in some embodiments, optionally, the shielding member 5 includes a telescopic member 56, one end of which is connected to the side wall of the enclosure 7, and the other end of which is connected to the coil disk 3. During the movement of the coil disk 3 relative to the support base 2, the telescopic member 56 can extend and retract with the movement of the coil disk 3.

[0097] In this embodiment, the shielding member 5 can also be a telescopic member 56. One end of the telescopic member 56 is connected to the reserve of the enclosure 7, and the other end is connected to the coil disk 3, so that the telescopic member 56 shields the gap 24, preventing debris from falling into the bottom of the enclosure 7 through the gap 24. At the same time, during the movement of the coil disk 3 relative to the support base 2, the telescopic member 56 can extend and retract, thereby avoiding obstruction of the movement of the coil disk 3.

[0098] In some embodiments, the retractable member 56 may optionally include an elastic structural member or a corrugated structural member.

[0099] In this embodiment, the telescopic member 56 includes an elastic structural member or a corrugated structural member. The elastic structural member can extend and retract under the action of tension or compression. The corrugated structural member is corrugated, so that the corrugated structural member can fold or unfold with the movement of the coil 3.

[0100] It is understandable that elastic structural components include silicone parts, rubber parts, etc. Corrugated structural components include foldable and unfoldable corrugated sheets, etc.

[0101] like Figure 2 and Figure 4 As shown, in some embodiments, optionally, when the cooking appliance includes an enclosure 7, the end of the enclosure 7 away from the opening 22 is provided with a support wall 70, the support wall 70 is disposed opposite to the opening 22 and the support wall 70 is provided with a through hole 72, and the drive assembly 4 is located on the side of the support wall 70 away from the heating container 8, wherein a part of the coil 3 extends out of the through hole 72 to the outside of the enclosure 7 and contacts the drive assembly 4, or a part of the drive assembly 4 extends into the enclosure 7 through the through hole 72 and contacts the coil 3.

[0102] In this embodiment, the bottom of the enclosure 7 is sealed by a support wall 70, and the support wall 70 is provided with a through hole 72, allowing the coil 3 located inside the enclosure 7 to cooperate with the drive assembly 4 located outside the enclosure 7. Either a portion of the coil 3 extends out through the through hole 72 to the outside of the enclosure 7 to contact and cooperate with the drive assembly 4, or a portion of the drive assembly 4 extends into the enclosure 7 through the through hole 72 to contact and cooperate with the coil 3. In the cooking appliance proposed in this application, the support wall 70 can support the coil 3 in the non-working state, improving the stability of the coil 3 and reducing the pressure of the coil 3 on the moving part 42. At the same time, the support wall 70 also prevents food residue or liquid from falling into the bottom of the casing, causing inconvenience in cleaning or damage to electrical components.

[0103] Optionally, a portion of the support wall 70 protrudes into the enclosure 7 to form a support structure, and the coil is sleeved on the support structure of the support wall 70 and slidably connected to the support structure.

[0104] In some embodiments, the support base 2, the enclosure 7, and the support wall 70 may be an integral structure.

[0105] In this embodiment, the support base 2, the enclosure 7, and the support wall 70 are an integral structure, which improves the connection strength between the three and reduces the assembly difficulty.

[0106] Optionally, the support base 2, the enclosure 7, and the support wall 70 are integrally formed structures.

[0107] like Figure 2 and Figure 4 As shown, in some embodiments, the support base 2 may optionally include an opening 26, a through-hole 22 disposed opposite to the opening 26, and the coil disk 3 exposed in the opening 26 along the circumference of the coil disk 3.

[0108] In this embodiment, the support base 2 includes an opening 26, through which the heating container 8 can be placed inside the support base 2. The outline of the coil 3 can be exposed through the opening 26, so that even when the heating container 8 is not placed inside the support base 2, the user can observe the maximum outline of the coil 3, so that the movement mode and position of the coil 3 can be intuitively displayed to the user.

[0109] like Figure 2 and Figure 8 As shown, in some embodiments, optionally, the drive assembly 4 includes: a drive part 40; a motion part 42 connected to the drive part 40, the motion part 42 having a first mating part 420, and the coil disk 3 having a second mating part 32, the first mating part 420 contacting the second mating part 32; wherein, the drive part 40 is capable of driving the motion part 42 to rotate, and the first mating part 420 rotates relative to the second mating part 32, so as to raise and lower the coil disk 3.

[0110] In this embodiment, the driving part 40 is provided with a first mating part 420, and the moving part 42 is provided with a second mating part 32. The first mating part 420 and the second mating part 32 are in contact. During the process of the driving part 40 driving the moving part 42 to rotate, the coil disk 3 is raised and lowered relative to the heating container 8 through the cooperation of the first mating part 420 and the second mating part 32. This allows the distance between the coil disk 3 and the heating container 8 to be adjusted, making the range of changes in the induced magnetic field of the heating container 8 larger and increasing the adjustable range of the heating power.

[0111] Optionally, one of the first mating part 420 and the second mating part 32 includes an inclined surface structure. The inclined surface structure is inclined relative to the axis of rotation of the moving part 42. During the process of the driving part 40 driving the moving part 42 to rotate, the other of the first mating part 420 and the second mating part 32 can slide along the inclined surface to realize the lifting and lowering of the coil disk 3.

[0112] like Figure 7 As shown, in some embodiments, optionally, one of the first mating portion 420 and the second mating portion 32 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 moving portion 42, and the other of the first mating portion 420 and the second mating portion 32 can alternately engage with the first protrusion 4200 and the first recess 4202 so that the coil disk 3 moves between being close to the heating container 8 and away from the heating container 8.

[0113] In this embodiment, the first mating part 420 and the second mating part 32 achieve the switching from rotation to linear movement through a concave-convex structure. One of the first mating parts 420 and 32 includes a first protrusion 4200 and a first concave part 4202. As the first mating part 420 rotates with the moving part 42, the other of the first mating part 420 and the other of the second mating part 32 alternately passes through the first protrusion 4200 and the first concave part 4202, thereby realizing the reciprocating lifting and lowering of the first coil 3. When the other of the first mating part 420 and the other of the second mating part 32 engages with the first protrusion 4200, the first mating part 420 and the other of the second mating part 32 together lift the coil 3, bringing it closer to the heating container 8. When the other of the first mating part 420 and the other of the second mating part 32 engages with the first concave part 4202, the coil 3 descends, moving it away from the heating container 8.

[0114] like Figure 4 and Figure 8 As shown, in some embodiments, optionally, the other of the first mating portion 420 and the second mating portion 32 includes a support leg 320; the support leg 320 can sequentially contact the first protrusion 4200 and the first recess 4202 to raise and lower the coil disk 3.

[0115] In this embodiment, one of the first mating part 420 and the second mating part 32 includes a first protrusion 4200 and a first recess 4202, and the other includes a support leg 320. During the process of the driving part 40 driving the moving part 42 to rotate, the support leg 320 passes through the first protrusion 4200 and the first recess 4202 in sequence, so that the support leg 320 moves up and down along the axis of rotation of the moving part 42, thereby realizing the lifting and lowering of the coil disk 3.

[0116] Optionally, the first mating part 420 includes a first protrusion 4200 and a first recess 4202, and the second mating part 32 includes a support leg 320. The first protrusion 4200 protrudes toward the coil disk 3 along the axis of rotation of the moving part 42, and the first recess 4202 is recessed away from the coil disk 3.

[0117] Optionally, there may be multiple feet 320. The arrangement of multiple feet 320 can improve the connection stability between the drive component 4 and the coil disk 3, thereby ensuring the stability of the drive of the coil disk 3.

[0118] Optionally, such as Figure 2 As shown, the drive component 4 drives the coil disk 3 to move up and down along the direction of motion C.

[0119] Optionally, the direction of movement C is the direction of the axis of the support 2.

[0120] In some embodiments, the end of the support leg 320 is provided with a protrusion 322, and the support leg 320 contacts the first protrusion 4200 and the first recess 4202 through the protrusion 322.

[0121] In this embodiment, the support leg 320 contacts the first protrusion 4200 or the first recess 4202 through the protrusion 322, thereby reducing the contact area between the support leg 320 and the first protrusion 4200 or the first recess 4202.

[0122] In some embodiments, the first mating portion 420 may optionally include a first protrusion 4200 and a first recess 4202, and the second mating portion 32 may include a second protrusion and a second recess, with the second protrusion and the second recess being alternately arranged along the rotational circumference of the moving portion 42.

[0123] In this embodiment, both the first mating portion 420 and the second mating portion 32 have a concave-convex structure, which improves the contact stability of the first mating portion 420 and the second mating portion 32. The first mating portion 420 includes a first protrusion 4200 and a first recess 4202, and the second mating portion 32 includes a second protrusion and a second recess. When the first protrusion 4200 and the second protrusion are in contact, the first recess 4202 is positioned opposite to the second recess, and the coil disk 3 is at its highest position. When the second protrusion is located within the first recess 4202, the first protrusion 4200 is located within the second recess, and the coil disk 3 is at its lowest position.

[0124] Optionally, there are multiple first protrusions 4200 and multiple first recesses 4202, and multiple second protrusions and multiple second recesses. Multiple first protrusions 4200 and multiple first recesses 4202 are alternately arranged along the circumference of the moving part 42, and multiple second protrusions and multiple second recesses are alternately arranged along the circumference of the moving part 42.

[0125] like Figure 7 As shown, 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.

[0126] In this embodiment, the first protrusion 4200 and the first recess 4202 are sequentially connected along the rotation direction of the moving part 42. This makes the movement of the coil 3 smoother during the rotation of the moving part 42, and also allows the coil 3 to continuously rise and fall with the continuous rotation of the moving part 42. This causes the induced magnetic field of the heating container 8 to continuously change, 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, so that the rising and falling of the coil 3 is not continuous, achieving intermittent rising and falling of the coil 3.

[0127] Optionally, the rotation direction of the moving part 42 can be Figure 7 The clockwise direction can also be counterclockwise.

[0128] Optionally, the heights of the first protrusion 4200 and the first concave portion 4202 gradually change along the rotation direction of the moving portion 42. For example, the height of the first protrusion 4200 gradually decreases from the middle to both ends, and the height of the first concave portion 4202 gradually increases from the middle to both ends.

[0129] like Figure 2 , Figure 4 and Figure 7 As shown, in some embodiments, optionally, the drive unit 40 includes a drive motor 400; the motion unit 42 includes a first gear 422 and a second gear 424, the second gear 424 is connected to the drive motor 400, a first mating part 420 is disposed on the first gear 422, the first gear 422 meshes with the second gear 424, or the motion unit 42 includes a turntable, the first mating part 420 is disposed on the side of the turntable facing the coil disk 3, and the drive motor 400 is disposed in the middle of the turntable to drive the turntable to rotate.

[0130] In this embodiment, the drive unit 40 includes a drive motor 400, and the motion unit 42 includes a first gear 422 and a second gear 424. The drive motor 400 is connected to the second gear 424, and the first gear 422 meshes with the second gear 424. The drive motor 400 drives the first gear 422 to rotate through the second gear 424. In this way, the drive motor 400 can be placed around the first gear 422, reducing the overall height of the cooking appliance. The cooking appliance proposed in this application realizes the lifting and lowering of the coil 3 through the rotation of the drive motor 400 and the gear structure, making the lifting and lowering of the coil 3 more stable and reliable. At the same time, converting rotation into lifting motion can also reduce the space occupied by the drive component 4 in the height direction. Alternatively, the motion unit 42 includes a turntable, and the first mating part 420 is disposed on the side of the turntable near the coil 3. The drive motor 400 is connected to the middle of the turntable, so that the drive motor 400 directly drives the turntable to rotate, reducing the number of transmission components.

[0131] In some embodiments, optionally, when the moving part 42 includes a first gear 422 and a second gear 424, the first gear 422 has an annular structure, and the first mating part 420 is disposed on the inner sidewall of the first gear 422 and the first mating part 420 is arranged in an annular manner.

[0132] In this embodiment, when the moving part 42 includes a first gear 422 and a second gear 424, the first gear 422 has an annular structure, that is, the first gear 422 is hollow inside. The teeth of the first gear 422 are arranged on the outer periphery of the first gear 422, and the first mating part 420 is arranged in annular shape in the hollow part inside the first gear 422, which greatly reduces the weight of the first gear 422, thereby helping to reduce the driving energy consumption of the driving part 40.

[0133] like Figure 4 As shown, in some embodiments, the cooking appliance may optionally include: at least one elastic element 6, the at least one elastic element 6 being disposed on the side of the moving part 42 away from the coil 3, the elastic element 6 being in a compressed state; and / or at least one elastic element 6 being disposed on the outer side wall of the support base 2 and located between the bottom wall of the support base 2 and the moving part 42, the elastic element 6 being in a stretched state.

[0134] In this embodiment, an elastic element 6 is provided on the side of the moving part 42 away from the coil disk 3 and / or between the bottom wall of the support base 2 and the moving part 42. Under the action of the elastic element 6, the coil disk 3 and the moving part 42 are firmly in contact, thereby ensuring the reliability of the movement of the coil disk 3.

[0135] Optionally, the elastic element 6 includes a spring or a sheet.

[0136] In some embodiments, the coil 3 can optionally be raised and lowered between a first position close to the heating container 8 and a second position far from the heating container 8, wherein the distance H1 between the first position and the second position is greater than 0 mm and less than or equal to 100 mm.

[0137] In this embodiment, the lifting range H1 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.

[0138] In practical applications, the distance H1 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.

[0139] In some embodiments, the drive component 4 is optionally used to drive the coil disk 3 to reciprocate between a first position and a second position, or to drive the coil disk 3 to move to any position between the first position and the second position.

[0140] In this embodiment, during the cooking process, the drive component 4 drives the coil 3 to move, allowing the coil 3 to reciprocate between near and away from the heating container 8. This causes the heating power of the cooking appliance to continuously change, resulting in the food inside the heating container 8 tumbling repeatedly. This tumbling action stirs the food within the heating container 8, improving the cooking effect. Alternatively, the drive component 4 can control the coil 3 to move to any position between the first and second positions according to different cooking stages, making the heating power infinitely adjustable.

[0141] In some embodiments, optionally, a coil is wound on the support 2, and the coil on the support 2 can surround the heating container 8. When the coil on the support 2 is energized, it can generate a magnetic field to make the heating container 8 heat up.

[0142] In this embodiment, a coil is wound on the support base 2, and the coil on the support base 2 surrounds the heating container 8. When the coil on the support base 2 is energized, the heating container 8 can be heated. That is, both the coil on the coil disk 3 and the coil on the support base 2 can heat the heating container 8. Optionally, the coil on the coil disk 3 and the coil on the support base 2 can heat the heating container 8 simultaneously, or the coil on the coil disk 3 and the coil on the support base 2 can heat the heating container 8 separately.

[0143] Optionally, the support base 2 is a one-piece molded structure.

[0144] Alternatively, the cooking appliance may include a rice cooker or an electric pressure cooker.

[0145] In some embodiments, optionally, the drive unit 40 includes a hydraulic pump, the motion unit 42 includes a hydraulic cylinder, the hydraulic cylinder is provided with a first support rod, the coil disk 3 is provided on the first support rod, and the hydraulic pump drives the first support rod to rise and fall to drive the coil disk 3 to rise and fall; and / or the drive unit 40 includes a pneumatic pump, the motion unit 42 includes a sealed cavity, a second support rod is provided on one side of the sealed cavity, the coil disk 3 is provided on the second support rod, and the pneumatic pump drives the second support rod to rise and fall to drive the coil disk 3 to rise and fall; and / or the drive unit 40 includes a first magnetic element, the motion unit 42 includes a second magnetic element, at least one of the first magnetic element and the second magnetic element is an electromagnet, the second magnetic element is connected to the coil disk 3, and when the electromagnet is energized, the first magnetic element and the second magnetic element attract or repel each other, causing the second magnetic element to move to push the coil disk 3 to rise and fall.

[0146] In this embodiment, the drive unit 40 can also directly drive the motion unit 42 to rise and fall, thereby raising and lowering the coil disc 3. For example, the drive unit 40 includes a hydraulic pump, and the motion unit 42 includes a hydraulic cylinder. The hydraulic cylinder is equipped with a first support rod. When the hydraulic pump operates, it drives the hydraulic cylinder to extend and retract, thereby causing the first support rod to raise and lower the coil disc 3. This makes the distance between the coil disc 3 and the heating container 8 adjustable, and thus the heating power adjustable. Alternatively, the drive unit 40 includes a pneumatic pump and a sealed cavity. The pneumatic pump drives the sealed cavity to expand or shrink, thereby causing the second support rod to raise and lower the coil disc 3. Or, the drive unit 40 includes a first magnetic element, and the motion unit 42 includes a second magnetic element. At least one of the first and second magnetic elements is an electromagnet. When the electromagnet is energized, the first and second magnetic elements attract or repel each other, thereby causing the second magnetic element to move. That is, the second magnetic element drives the coil disc 3 to rise and fall, thereby adjusting the distance between the coil disc 3 and the heating container 8, and thus adjusting the heating power.

[0147] In some embodiments, the cooking appliance may optionally include a magnetic shielding cover, which is disposed on the outside of the drive unit 40 to shield the drive unit 40 from magnetic interference.

[0148] In this embodiment, since the drive unit 40 contains a metal material, it is easily heated in a magnetic field. Therefore, the drive unit 40 is covered with a magnetic shield to isolate the magnetic field generated by the first coil on the coil disk 3, thereby avoiding the situation where the magnetic field generated by the first coil affects the performance of the drive unit 40 due to overheating.

[0149] According to one embodiment of this application, the cooking appliance proposed in this application includes a coil 3 located at the lower end of a heating container 8, and is movable up and down relative to the heating container 8, such that the coil moves away from and closer to the inner pot (e.g., the heating container 8).

[0150] Optionally, the drive motor 400 is mounted on a large coil (e.g., support base 2). The drive motor 400 drives a small gear (e.g., second gear 424), which meshes with a large gear (e.g., first gear 422) to transmit power to the lifting plate (e.g., coil 3), thereby enabling the lifting plate to move up and down, changing the distance between the coil 3 and the inner pot, and thus changing the electromagnetic parameters.

[0151] Optionally, coils are wound on the lifting plate and the large coil. When the coils are energized, they generate a magnetic field to heat the inner pot. Alternatively, the large coil may not be wound with coils, and heating can be achieved solely by the coils wound on the lifting plate.

[0152] Optionally, the lifting plate is located inside the cavity of the large coil 3, and the lifting plate can be seen from the opening 26 direction. The lifting plate is completely enclosed by the large coil 3.

[0153] Optionally, when the rice cooker is opened and the inner pot is not placed, the maximum projected circular outline of the winding space of the entire lifting plate can be seen.

[0154] Optionally, the lifting plate is located inside the cavity of the large coil 3, and the movable distance H1 is preferably 0mm-100mm. The coil 3 is located directly at the bottom of the inner pot, which maximizes the heating efficiency. Furthermore, the change in the position of the coil 3 makes it easier to cause changes in electromagnetic parameters. In other words, a large range of parameter changes can be met within a small lifting space. This helps to reduce the space requirements of the lifting system and make the product more compact.

[0155] Optionally, the pinion and the gear rotate horizontally. In order to convert the horizontal motion into the up-and-down motion of the lifting plate, a groove 520 is designed on the gear (thus forming the first protrusion 4200 and the first concave portion 4202), that is, a trajectory with a height difference.

[0156] Optionally, the lifting plate is designed with a lifting support (e.g., support leg 320), which directly or indirectly contacts the first protrusion 4200 and the first concave portion 4202 of the large gear, thereby achieving lifting and lowering. This allows the coil on the lifting plate to move closer to or further away from the heating container 8, thus changing the magnetic field and facilitating performance and other adjustments by the electronic control system.

[0157] Optionally, the lifting plate moves up and down, and there is a certain gap 24 between it and the large coil. In order to prevent debris from falling through the gap 24 and jamming the coil 3, the minimum horizontal gap 24 can be 0mm-60mm, and it is better to have a small gap 24.

[0158] Alternatively, silicone (e.g., shielding part 5) can be used to cover the periphery of the lifting plate. The silicone includes a groove 520, the diameter of which is smaller than the diameter of the lifting plate, so that the groove 520 interferes with the lifting plate. In this way, the silicone can be reliably fixed on the lifting plate. In addition, the outer ring of the silicone is designed with small ribs (e.g., protrusions 54). The small ribs reduce the gap 24 between the lifting plate and the large coil, or cause slight interference. The ribs have a small contact surface, resulting in less friction during lifting and lowering, thus providing a certain degree of reliability.

[0159] Alternatively, to prevent foreign objects from entering, retractable flexible components (such as telescopic parts) can be connected to the two parts (such as the large reel and the lifting plate) respectively to achieve a completely gapless 24.

[0160] The cooking appliance proposed in this application, specifically for electromagnetic heating products, features a movable coil 3. By moving the movable coil 3 "away" and "closer" to the heating container 8, the range of induced magnetic field variations within the inner liner of the heating container 8 is expanded, facilitating adjustments to the electronic control performance. Simultaneously, the lifting plate is located directly below the heating container 8. When the heating container 8 is not in use, the maximum projected circle of the lifting plate's winding position is visible. To prevent debris from entering the lifting joint, silicone or other flexible components can be used to achieve a zero gap 24 or reduce this gap 24.
