Description

Technical Field

[0001] This application relates to the field of kitchen appliance technology, and more particularly to a coil and a stove. Background Technology

[0002] An induction cooker is a common cooking appliance with advantages such as high heating efficiency, fast heating speed, and safe use of electric heating.

[0003] Traditional induction cookers cannot directly heat non-magnetic cookware. Related technologies utilize a magnetically conductive metal plate placed between the excitation coil and the cooktop. The metal plate senses the magnetic field of the excitation coil and generates eddy currents, which in turn generate heat in the metal plate, transferring this heat to the non-magnetic cookware.

[0004] However, due to the high temperature of the metal plate, the heat from the metal plate can easily be conducted to the excitation coil, thereby affecting the service life and safety of the excitation coil. Utility Model Content

[0005] Based on this, this application provides a coil disc and a stove. The heat insulation of the coil disc has a better heat insulation effect, thereby reducing the heat conduction from the magnetic induction element to the first coil, thus improving the service life and safety of the first coil.

[0006] The coil disk provided in this application has a heating side, and the coil disk includes:

[0007] The first bracket is provided with a first wire groove;

[0008] The first coil is wound in the first wire groove;

[0009] The heat insulation component, at least part of which is located on the side of the first groove facing the heating side, the side of the heat insulation component away from the heating side abuts against the first bracket, the side of the heat insulation component away from the heating side has a non-abutting surface opposite to the first groove, and a first gap T1 is formed between the non-abutting surface and the top surface of the first groove facing the heating side.

[0010] The magnetic sensing element is located on the side of the heat insulation element facing the heating side and is configured to generate heat under the action of the magnetic field of the first coil.

[0011] The coil disc provided in this embodiment improves stove safety by using a heat-insulating component to fix the magnetic sensing component and reduce heat conduction from the magnetic sensing component to the first coil. Because there is a first gap between the top surface of the first groove and the non-contact surface of the heat-insulating component, contact between the heat-insulating component and the first coil within the first groove is prevented. This effectively prevents heat from the magnetic sensing component from being conducted to the first coil through the heat-insulating component, thereby improving the lifespan and safety performance of the coil disc. Furthermore, the top of the first groove and the non-contact surface can form a heat dissipation channel, facilitating airflow and further improving the heat dissipation performance of the coil disc.

[0012] In one possible implementation, the first gap T1 is greater than or equal to 0.5 mm and less than or equal to 10 mm.

[0013] In this way, a sufficiently large heat dissipation channel can be defined between the first wire groove and the heat insulation component, which is conducive to ventilation and heat dissipation, thereby improving the heat dissipation performance of the first coil. Furthermore, it is beneficial to control the distance between the magnetic induction component and the first coil, thereby ensuring the heat generation efficiency of the magnetic induction component and improving the heating effect of the coil disc.

[0014] In one possible implementation, the first bracket is further provided with a support surface, the first wire groove and the support surface are both located on the side of the first bracket facing the heating side, and the support surface is disposed closer to the heating side relative to the first wire groove, and the support surface is located on at least one side of the radial direction of the first coil.

[0015] The side of the heat insulation component facing away from the heating side has an abutment surface, which abuts against the support surface.

[0016] Thus, when the contact surface of the heat insulation component comes into contact with the support surface of the first bracket, the first bracket can stably support the heat insulation component, which is conducive to reliably installing the heat insulation component on the first bracket. Since the support surface is higher than the first wire groove, the heat insulation component can be raised relative to the first wire groove, thereby causing a first gap to be formed between the non-contact surface and the first wire groove, thus preventing the heat insulation component from contacting the first coil.

[0017] In one possible implementation, the support surface includes a first support surface and a second support surface, the first support surface being disposed radially inside the first coil and the second support surface being disposed radially outside the first coil;

[0018] The contact surface includes a first contact surface and a second contact surface; the first contact surface abuts against the first support surface, and the second contact surface abuts against the second support surface. Thus, by providing the first support surface to support the inner side of the thermal insulation component and the second support surface to support the outer side of the thermal insulation component, the support stability of the support surface on the thermal insulation component is improved.

[0019] In one possible implementation, one of the first contact surface and the second contact surface is flush with the non-contact surface;

[0020] The first support surface and the second support surface are arranged parallel to each other, and one of the first support surface and the second support surface is arranged closer to the heating side than the other, or the first support surface and the second support surface are located on the same plane.

[0021] Thus, when the non-abutting surface is flush with the first supporting surface and the first supporting surface is positioned closer to the heating side relative to the second supporting surface, or when the non-abutting surface is flush with the second supporting surface and the second supporting surface is positioned closer to the heating side relative to the first supporting surface, a larger first gap can be formed between the top surface of the first slot and the non-abutting surface. This allows for the formation of a larger heat dissipation channel between the top surface of the first slot and the non-supporting surface, which is beneficial for ventilation and heat dissipation, thereby improving the safety of the coil. When the first supporting surface and the second supporting surface are located on the same plane, the support stability of the first supporting surface and the second supporting surface on the heat insulation component can be improved.

[0022] In one possible implementation, the coil disk further includes a second coil and a second support, the second support being connected to the outer periphery of the first support;

[0023] The second coil is wound on the second support, and the winding direction of the second coil is the same as that of the first coil;

[0024] At least part of the heat insulation component is positioned between the second coil and the magnetic sensing component, and the second bracket has a second gap T2 between its inner surface facing the first bracket and the heat insulation component.

[0025] Thus, by placing a second coil outside the first coil, a magnetic field is generated on the outer side of the magnetic sensing element, thereby increasing the eddy current effect of the magnetic sensing element and improving its heat generation efficiency. Since the heat insulation element is positioned between the second coil and the magnetic sensing element, it prevents heat from the magnetic sensing element from being conducted to the second coil. Furthermore, a second gap is formed between the second support and the heat insulation element, preventing heat from the magnetic sensing element from being conducted to the second support through the heat insulation element, and subsequently to the second coil. This prevents the outer protective layer of the second support and the second coil from melting due to excessive temperature, thereby improving the structural stability and safety of the coil coil.

[0026] In one possible implementation, the second gap T2 is greater than or equal to 0.5 mm and less than or equal to 20 mm.

[0027] In this way, the inner surface of the second support is kept away from the heat insulation component, thereby preventing the heat of the magnetic sensing component from being conducted to the second support through the heat insulation component. It also helps to ensure that the magnetic field generated by the second coil acts on the magnetic sensing component, thereby increasing the eddy current effect of the magnetic sensing component and improving the heat generation efficiency of the magnetic sensing component.

[0028] In one possible implementation, the coil disk further includes a magnetic strip assembly disposed on at least one side of at least one of the first coil and the second coil; at least one of the first bracket and the second bracket is provided with a mounting portion, and at least a portion of the magnetic strip assembly is inserted into the mounting portion.

[0029] In this way, the magnetic strip assembly can enhance the magnetic field strength of the first coil and the second coil, and the mounting part can be used to install the magnetic strip assembly, thereby fixing the magnetic strip assembly to the first bracket or the second bracket.

[0030] In one possible implementation, the mounting portion includes a first mounting portion and a second mounting portion, the first mounting portion being located on the outer side of the first bracket facing the second bracket, and the second mounting portion being located on the outer side of the second bracket away from the first bracket.

[0031] The magnetic strip assembly includes a first magnetic part and a second magnetic part. The first magnetic part includes a first sub-magnetic part, and the second magnetic part includes a second sub-magnetic part. Both the first sub-magnetic part and the second sub-magnetic part extend along the axial direction of the first coil. The first sub-magnetic part is inserted into the first mounting part, and the second sub-magnetic part is inserted into the second mounting part.

[0032] In this way, the first magnetic part can be fixed to the first bracket by the cooperation of the first sub-magnetic part and the first mounting part, and the second magnetic part can be fixed to the second bracket by the cooperation of the second sub-magnetic part and the second mounting part, thereby fixing the magnetic strip assembly to the bracket assembly as a whole.

[0033] In one possible implementation, the first support is provided with a plurality of ventilation openings, which penetrate both sides of the first support along the axial direction of the first coil, and the plurality of ventilation openings are arranged at intervals along the circumference of the first coil.

[0034] Thus, by setting vents on the first bracket to facilitate ventilation and heat dissipation, the heat of the coil assembly is carried away by air circulation, which helps to reduce the temperature of the coil assembly.

[0035] In one possible implementation, the coil also includes a connector, and the first support is further provided with a connection hole, the connector being configured to connect the stove housing and the connection hole.

[0036] In this way, the coil can be fixed to the housing by connecting the connecting holes, thereby improving the overall stability of the stove.

[0055] In view of the above problems, embodiments of this application provide a coil and a stove, wherein a heat insulation component is placed between the first coil and the magnetic sensing component to reduce heat conduction between the magnetic sensing component and the first coil, and a first gap is provided between the first wire groove and the support surface to prevent the heat of the magnetic sensing component from being conducted to the first coil through the heat insulation component, thereby preventing the first coil from melting, thereby improving the service life and safety of the first coil.

[0056] The specific implementation methods of the coil and stove provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0057] The stove provided in this application embodiment can be an induction cooker or an induction stove, and this application embodiment does not limit it.

[0058] Reference Figures 1 to 9 As shown, the stove in this embodiment of the application includes a housing and a coil. The housing includes a panel 100, which is configured to contact the cookware. The coil has a heating side, which is the side of the coil facing the cookware, so that the coil can heat the cookware.

[0059] The coil includes a support assembly 200, a coil assembly 300, a heat insulation element 400, and a magnetic sensing element 500. The support includes a first support 210, which has a support surface 211 and a first wire groove 212. The support surface 211 and the first wire groove 212 are both located on the side of the first support 210 closest to the panel 100, and the first wire groove 212 is located on the side of the support surface 211 away from the panel 100. The coil assembly 300 includes a first coil 310, which is wound around the first wire groove 212. The side of the heat insulation element 400 away from the panel 100 abuts against the support surface 211. The magnetic sensing element 500 is located on the side of the heat insulation element 400 facing the panel 100 and is configured to heat up under the magnetic field of the first coil 310 to heat the cookware.

[0060] A first gap T1 exists between the top surface of the first wire groove 212 facing the panel 100 and the bottom surface of the heat insulation member 400 facing away from the panel 100. That is, the heat insulation member 400 has an abutting surface that abuts against the support surface 211, and the heat insulation member 400 also has a non-abutting surface 430 disposed opposite to the first wire groove 212. The abutting surface is located on the inner side of the non-abutting surface 430 along the radial direction of the first coil 310, or the abutting surface is located on the outer side of the non-abutting surface 430 along the radial direction of the first coil 310. The non-abutting surface 430 and the top surface of the first wire groove 212 facing the panel 100 have a first gap T1.

[0061] In this embodiment, the panel 100 can be used to provide a support surface for the cookware, so that the cookware can be stably placed on the stove. The bracket assembly 200 is used to install the coil assembly 300 and the heat insulation component 400, etc., and the coil assembly 300 and the heat insulation component 400 are assembled together by the bracket assembly 200, thereby ensuring the overall stability of the coil.

[0062] The coil assembly 300 is used to generate an alternating magnetic field when energized, so as to generate eddy currents in the magnetic sensing element 500 through the alternating magnetic field, thereby causing the magnetic sensing element 500 to heat up itself, so that the magnetic sensing element 500 heats the non-magnetic cookware through thermal radiation.

[0063] It should be understood that regardless of whether the cookware is magnetic or non-magnetic, the heat from the magnetic induction element 500 can be conducted to the cookware, thereby heating it. When the cookware is magnetic, the magnetic field of the coil assembly 300 can act on the magnetic induction element 500, thereby heating the cookware through the magnetic induction element 500. Furthermore, the magnetic field of the coil assembly 300 can also act on the cookware, causing it to generate heat on its own. The electromagnetic heating and infrared radiation heating work together to improve the heating effect of the magnetic cookware.

[0064] Therefore, when using the stove, the limitations of cookware materials can be overcome. Whether using magnetic or non-magnetic cookware, the stove of this embodiment can be used for cooking, making the stove highly versatile. The magnetic induction element 500 can be made of a material with high magnetic permeability, such as ferrite or silicon steel sheet, to efficiently generate heat under the magnetic field generated by the coil assembly 300.

[0065] The heat insulation component 400 is used to fix the magnetic sensing component 500 and to block the heat of the magnetic sensing component 500 from being conducted to the coil assembly 300, thereby preventing the coil assembly 300 from causing safety problems due to high temperature.

[0066] Specifically, the bracket assembly 200 includes a first bracket 210, which has a first wire groove 212. The coil assembly 300 includes a first coil 310. After the first coil 310 is wound inside the first coil 310, the first coil 310 can be stably fixed on the first bracket 210, thereby preventing the first coil 310 from moving randomly. The first coil 310 can provide a magnetic field to the bottom of the magnetic sensing element 500, thereby causing the magnetic sensing element 500 to generate eddy currents and heat up.

[0067] The first bracket 210 is also provided with a support surface 211, which is used to support the heat insulation component 400, thereby making the heat insulation component 400 stably disposed in the bracket assembly 200. For example, the heat insulation component 400 can be fixed to the first bracket 210 by threaded fasteners, or the heat insulation component 400 can be fixed to the first bracket 210 by adhesive.

[0068] Since the first groove 212 is positioned away from the panel 100 relative to the support surface 211, that is, when the stove is placed on a horizontal surface or installed horizontally on the stovetop, the first groove 212 is located below the support surface 211, and there is a first gap between the top surface of the first groove 212 and the support surface 211, when the heat insulation component 400 abuts against the support surface 211, there is also a first gap between the heat insulation component 400 and the top surface of the first groove 212. The heat insulation component 400 will not come into contact with the first coil 310 located in the first groove 212, thereby preventing the heat of the magnetic sensing component 500 from being conducted to the first coil 310 through the heat insulation component 400, which helps to reduce the temperature of the first coil 310 and prevent the outer protective layer of the first coil 310 from melting due to excessive temperature.

[0069] Furthermore, after the heat insulation component 400 comes into contact with the support surface 211, a first gap exists between the top surface of the first groove 212 and the heat insulation component 400, thereby forming a heat dissipation channel by the top of the first groove 212 and the heat insulation component 400, which improves the heat dissipation performance of the stove.

[0070] It should be noted that the first coil 310 may include multiple turns of wire. After the wire is wound multiple times in the same direction, a disc-shaped first coil 310 can be formed. The winding direction of the first coil 310 is its axial direction, and the radial direction of the first coil 310 is perpendicular to its axial direction.

[0071] The stove provided in this embodiment includes a panel 100, a first support 210, a first coil 310, a heat insulation component 400, and a magnetic sensing component 500. The first support 210 includes a support surface 211 and a first groove 212. The panel 100 supports the cookware, allowing it to sit stably on the stove. The first groove 212 is used to mount the first coil 310, and the support surface 211 is used to mount the heat insulation component 400. The first support 210 integrates the first coil 310 and the heat insulation component 400 together. The first coil 310 generates an alternating magnetic field when energized, causing the magnetic sensing component 500 to induce eddy currents and generate heat, which is then radiated to non-magnetic cookware, thus improving the stove's versatility. The heat insulation component 400 fixes the magnetic sensing component 500 and reduces heat conduction from the magnetic sensing component 500 to the first coil 310, thereby improving the stove's safety. Because there is a first gap between the top surface and the non-contact surface 430 of the first groove 212, the heat insulation member 400 is prevented from contacting the first coil 310 inside the first groove 212, thereby preventing the heat from the magnetic sensing member 500 from being conducted to the first coil 310 through the heat insulation member 400. Furthermore, the top surface and the non-contact surface 430 of the first groove 212 can form a heat dissipation channel, which is conducive to airflow and thus improves the heat dissipation performance of the stove. Therefore, the stove of this embodiment has high versatility and safety.

[0072] In some implementations, the first gap T1 is greater than or equal to 0.5 mm, and the first gap T1 is less than or equal to 10 mm.

[0073] It should be noted that if the first gap is less than 0.5 mm, the heat dissipation channel formed by the top of the first groove 212 and the heat insulation component 400 is too narrow, which is not conducive to ventilation and heat dissipation. If the first gap is greater than 10 mm, the distance between the magnetic sensing component 500 and the first coil 310 will be too far, thereby reducing the magnetic field strength of the magnetic sensing component 500 and thus reducing the heat generation efficiency of the magnetic sensing component 500.

[0074] Therefore, in this embodiment, the first gap is between 0.5 mm and 10 mm to ensure that a sufficiently large heat dissipation channel is defined between the first wire groove 212 and the heat insulation member 400, which is conducive to ventilation and heat dissipation, thereby improving the heat dissipation performance of the first coil 310. In addition, it is beneficial to control the distance between the magnetic sensing member 500 and the first coil 310, thereby ensuring the heat generation efficiency of the magnetic sensing member 500 and improving the heating effect of the furnace.

[0075] For example, the first gap can be any one of 0.5 mm, 1 mm, 2 mm, 5 mm, 8 mm, or 10 mm, or fall within the range of any two values. This application embodiment does not limit this.

[0076] Reference Figure 8 , Figure 9As shown, in one possible implementation, the heat insulation member 400 has a first abutment surface 410 and a second abutment surface 420 on the side facing away from the panel 100, and the first support surface 2111 is disposed close to the panel 100 relative to the second support surface 2112. The first abutment surface 410 abuts against the first support surface 2111, and the second abutment surface 420 abuts against the second support surface 2112.

[0077] Thus, when the first abutting surface 410 abuts against the first supporting surface 2111, and the second abutting surface 420 abuts against the second supporting surface 2112, the heat insulation component 400 can be stably supported on the first bracket 210, thereby improving the stability of the heat insulation component 400. (Refer to...) Figure 6 As shown, in some embodiments, the support surface 211 includes a first support surface 2111 and a second support surface 2112 disposed radially inward and outward along the first coil 310, with the first support surface 2111 and the second support surface 2112 disposed parallel to each other. The first support surface 2111 is disposed close to the panel 100 relative to the second support surface 2112, and both the first support surface 2111 and the second support surface 2112 abut against the heat insulation member 400.

[0078] It is understood that, compared to supporting only the inner or outer side of the heat insulation component 400, providing support surfaces 211 on both the inner and outer sides of the heat insulation component 400 can improve the support stability of the heat insulation component 400. Therefore, in this embodiment, by providing a first support surface 2111 to support the inner side of the heat insulation component 400 and by providing a second support surface 2112 to support the outer side of the heat insulation component 400, the support stability of the support surface 211 on the heat insulation component 400 is improved.

[0079] Reference Figure 8 As shown, the side of the heat insulation component 400 away from the heating side is also provided with a non-abutting surface 430. The non-abutting surface 430 is located between the first abutting surface 410 and the second abutting surface 420. One of the first abutting surface 410 and the second abutting surface 420 is flush with the non-abutting surface 430. The non-abutting surface 430 is arranged opposite to the first coil 310.

[0080] In some implementations, the first support surface 2111 and the second support surface 2112 are arranged in parallel, with one of the first support surface 2111 and the second support surface 2112 being positioned closer to the heating side relative to the other.

[0081] In this way, since the first support surface 2111 is positioned closer to the panel 100 than the second support surface 2112, and the non-abutting surface 430 is flush with the first support surface 2111, a larger first gap can be formed between the top surface of the first groove 212 and the non-abutting surface 430. This allows the non-abutting surface 430 and the first groove 212 to enclose a larger heat dissipation channel, which is beneficial for ventilation and heat dissipation, thereby improving the safety of the stove.

[0082] Or, refer to Figure 9 As shown, since the second support surface 2112 is positioned closer to the panel 100 than the first support surface 2111, and the non-abutting surface 430 is flush with the second support surface 2112, a larger first gap can be formed between the top surface of the first groove 212 and the non-abutting surface 430. This allows the non-abutting surface 430 and the first groove 212 to enclose a larger heat dissipation channel, which is beneficial for ventilation and heat dissipation, thereby improving the safety of the stove.

[0083] In other embodiments, the first support surface 2111 and the second support surface 2112 may be located on the same plane, that is, they are set at the same height, so that the first support surface 2111 and the second support surface 2112 can support the heat insulation component 400 more stably.

[0084] Reference Figures 3 to 8 As shown, in one possible implementation, the coil assembly 300 further includes a second coil 320, and the support assembly 200 further includes a second support 220, which is connected to the outer periphery of the first support 210. The second support 220 is provided with a second wire groove 222, and the second coil 320 is wound in the second wire groove 222, with the winding direction of the second coil 320 being consistent with that of the first coil 310.

[0085] At least part of the heat insulation element 400 is positioned between the second coil 320 and the magnetic sensing element 500, and the second bracket 220 has a second gap T2 between its inner surface facing the first bracket 210 and the heat insulation element 400.

[0086] In this way, by setting the second coil 320 outside the first coil 310, the second coil 320 generates a magnetic field on the outer part of the magnetic sensing element 500, thereby increasing the eddy current effect of the magnetic sensing element 500 and improving the heat generation efficiency of the magnetic sensing element 500.

[0087] Since the heat insulation component 400 is positioned between the second coil 320 and the magnetic sensing component 500, it can prevent the heat from the magnetic sensing component 500 from being conducted to the second coil 320. Furthermore, the second gap formed between the second support 220 and the heat insulation component 400 can prevent the heat from the magnetic sensing component 500 from being conducted to the second support 220 through the heat insulation component 400, and then to the second coil 320. This prevents the outer protective layer of the second support 220 and the second coil 320 from melting due to excessive temperature, thereby improving the structural stability and safety of the stove.

[0088] In some embodiments, the second gap T2 is greater than or equal to 0.5 mm, and the second gap T2 is less than or equal to 20 mm.

[0089] It should be noted that if the second gap is less than 0.5 mm, the inner surface of the second bracket 220 is almost in contact with the heat insulation component 400, and the heat of the magnetic sensing component 500 can be easily conducted to the second bracket 220 through the heat insulation component 400. If the second gap is greater than 20 mm, it will cause the distance between the second coil 320 and the magnetic sensing component 500 to be too far, thereby reducing the heat generation efficiency of the magnetic sensing component 500.

[0090] Therefore, in this embodiment, the second gap is between 0.5 mm and 20 mm, which can ensure that the inner surface of the second support 220 does not contact the heat insulation member 400, thereby preventing the heat of the magnetic sensing member 500 from being conducted to the second support 220 through the heat insulation member 400. It also helps to ensure that the magnetic field generated by the second coil 320 acts on the magnetic sensing member 500, so as to increase the eddy current effect of the magnetic sensing member 500 and thus improve the heat generation efficiency of the magnetic sensing member 500.

[0091] For example, the second gap can be any one of 0.5 mm, 2 mm, 4 mm, 7 mm, 10 mm, or 20 mm, or fall within the range of any two values. This application embodiment does not limit this.

[0092] Reference Figure 1 , Figure 3 As shown, in one possible implementation, the stove further includes a magnetic strip assembly 600, which is disposed on at least one side of at least one of the first coil 310 and the second coil 320. At least one of the first bracket 210 and the second bracket 220 is provided with a mounting portion, and at least a portion of the magnetic strip assembly 600 is inserted into the mounting portion.

[0093] In other words, the magnetic strip assembly 600 can be disposed on one or both sides of the first coil 310 to enhance the magnetic field strength of the first coil 310; or, the magnetic strip assembly 600 can be disposed on one or both sides of the second coil 320 to enhance the magnetic field strength of the second coil 320; or, the magnetic strip assembly 600 can be disposed on one or both sides of the first coil 310 and the second coil 320 to enhance the magnetic field strength of the first coil 310 and the second coil 320. Thus, by disposing of the magnetic strip assembly 600, the magnetic field strength of the coil assembly 300 is enhanced, thereby improving the heat generation efficiency of the magnetic sensing element 500.

[0094] The first bracket 210 may be provided with a mounting part for mounting the magnetic strip assembly 600, or the second bracket 220 may be provided with a mounting part for mounting the magnetic strip assembly 600, or both the first bracket 210 and the second bracket 220 may be provided with mounting parts for mounting the magnetic strip assembly 600, thereby fixing the magnetic strip assembly 600 to the bracket assembly 200.

[0095] Reference Figure 6 , Figure 8As shown, in some embodiments, the mounting portion includes a first mounting portion 213 and a second mounting portion 221. The first mounting portion 213 is disposed on the outer side of the first bracket 210 facing the second bracket 220, and the second mounting portion 221 is disposed on the outer side of the second bracket 220 away from the first bracket 210.

[0096] The magnetic strip assembly 600 includes a first magnetic part 610 and a second magnetic part 620. The first magnetic part 610 includes a first sub-magnetic part 611, and the second magnetic part 620 includes a second sub-magnetic part 621. Both the first sub-magnetic part 611 and the second sub-magnetic part 621 extend along the axial direction of the first coil 310. The first sub-magnetic part 611 is inserted into the first mounting part 213 and can be fixedly connected to the first mounting part 213 by adhesive. The second sub-magnetic part 621 is inserted into the second mounting part 221 and can be fixedly connected to the second mounting part 221 by adhesive.

[0097] With this configuration, the first magnetic part 610 can be fixed to the first bracket 210 by the cooperation of the first sub-magnetic part 611 and the first mounting part 213, and the second magnetic part 620 can be fixed to the second bracket 220 by the cooperation of the second sub-magnetic part 621 and the second mounting part 221, thereby fixing the magnetic strip assembly 600 as a whole to the bracket assembly 200.

[0098] The first sub-magnetic part 611 can be located outside the first coil 310, thereby guiding the magnetic field around the first coil 310 to converge towards the outer part of the magnetic sensing element 500. The second sub-magnetic part 621 can be located outside the second coil 320, thereby guiding the magnetic field of the second coil 320 to converge towards the outer part of the magnetic sensing element 500, thereby increasing the eddy current effect on the outer part of the magnetic sensing element 500 and thus increasing the temperature of the magnetic sensing element 500.

[0099] In one possible implementation, the first magnetic part 610 further includes a third sub-magnetic part 612, which is connected to one end of the first sub-magnetic part 611 away from the panel 100 and is correspondingly disposed on the side of the second coil 320 away from the panel 100. The second magnetic part 620 further includes a fourth sub-magnetic part 622, which is connected to one end of the second sub-magnetic part 621 away from the panel 100 and is correspondingly disposed on the side of the second coil 320 away from the panel 100.

[0100] The first bracket 210 has a first limiting surface 214, which is connected to one end of the first mounting part 213 away from the panel 100. The third sub-magnetic part 612 abuts against the first limiting surface 214. The second bracket 220 has a second limiting surface 223, which is connected to one end of the second mounting part 221 away from the panel 100. The fourth sub-magnetic part 622 abuts against the second limiting surface 223.

[0101] In this way, the third sub-magnetic part 612 can guide the magnetic field of the first coil 310 to converge towards the bottom of the magnetic sensing element 500, and the fourth sub-magnetic part 622 can guide the magnetic field of the second coil 320 to converge towards the bottom of the magnetic sensing element 500, and prevent the magnetic fields of the first coil 310 and the second coil 320 from radiating downwards towards the stove, thereby improving the electromagnetic compatibility of the stove.

[0102] Furthermore, when the first sub-magnetic part 611 is inserted into the first mounting part 213, if the third sub-magnetic part 612 abuts against the first limiting surface 214, it indicates that the first magnetic part 610 is installed in place. When the second sub-magnetic part 621 is inserted into the second mounting part 221, if the fourth sub-magnetic part 622 abuts against the second limiting surface 223, it indicates that the second magnetic part 620 is installed in place. This helps to improve the installation accuracy of the magnetic strip assembly 600.

[0103] Reference Figure 6 , Figure 9 As shown, at least part of the first magnetic part 610 may further include a fifth sub-magnetic part 613, and the first bracket 210 may also be provided with a third mounting part 217. The fifth sub-magnetic part 613 is inserted into the third mounting part 217. The fifth sub-magnetic part 613 is located inside the third sub-magnetic part 612 along the radial direction of the first coil 310. One end of the fifth sub-magnetic part 613 is connected to the third sub-magnetic part 612, and the other end extends along the axial direction of the first coil 310 toward the panel 100. In this way, the first magnetic part 610 can form a U-shaped magnetic strip structure to better guide the magnetic field of the first coil 310 to converge toward the magnetic sensing element 500, thereby enhancing the eddy current effect of the magnetic sensing element 500.

[0104] In some embodiments, the first limiting surface 214 and the second limiting surface 223 are offset along the axial direction of the first coil 310, and the second limiting surface 223 is positioned closer to the panel 100 relative to the first limiting surface 214.

[0105] In this way, when the magnetic strip assembly 600 is installed onto the bracket assembly 200, the first limiting surface 214 and the second limiting surface 223 can be used to ensure that there is a height difference between the third sub-magnetic part 612 and the fourth sub-magnetic part 622, and the fourth sub-magnetic part 622 is positioned close to the panel 100, which is beneficial for the second magnetic part 620 to guide the magnetic field around the second coil 320 to converge towards the center of the magnetic sensing element 500.

[0106] Reference Figure 8 As shown, in some embodiments, the offset distance T3 between the first limiting surface 214 and the second limiting surface 223 is greater than or equal to 1 mm, and the offset distance T3 between the first limiting surface 214 and the second limiting surface 223 is less than or equal to 30 mm.

[0107] It should be noted that if T3 is less than 1 mm, a significant height difference cannot be formed between the third sub-magnetic part 612 and the fourth sub-magnetic part 622, which in turn prevents the second magnetic part 620 from effectively guiding the magnetic field of the second coil 320 towards the center of the magnetizing element 500. If T3 is greater than 30 mm, the size of the magnetic strip assembly 600 in the axial direction of the first coil 310 will be too large, resulting in a larger height of the stove and thus increasing the size of the stove.

[0108] Therefore, in this embodiment, T3 is between 1 mm and 30 mm, which makes the fourth sub-magnetic part 622 significantly higher than the third sub-magnetic part 612. This facilitates the second magnetic part 620 in guiding the magnetic field around the second coil 320 to converge towards the center of the magnetic sensing element 500. Furthermore, it helps to control the size of the magnetic strip assembly 600 along the axial direction of the first coil 310, thereby helping to control the volume of the stove.

[0109] For example, T3 can be any value among 1 mm, 5 mm, 7 mm, 15 mm, 20 mm, and 30 mm, or fall within the range of any two values.

[0110] Reference Figure 4 and Figure 8 As shown, in some embodiments, the heat insulation member 400 includes a heat insulation pad 400a and a first heat insulation flange 400b. The first heat insulation flange 400b is connected to the outer periphery of the heat insulation pad 400a and is disposed near the panel 100 relative to the heat insulation pad 400a. The heat insulation pad 400a is positioned between the magnetic sensing element 500 and the first coil 310, and the first heat insulation flange 400b is positioned between the magnetic sensing element 500 and the second coil 320. The side of the heat insulation pad 400a facing away from the panel 100 abuts against the support surface 211.

[0111] With this configuration, when the side of the heat insulation pad 400a facing away from the panel 100 comes into contact with the support surface 211, the heat insulation component 400 can be stably supported on the first bracket 210. The heat insulation pad 400a can block the heat of the magnetic sensing component 500 from being conducted to the first coil 310, thereby preventing the temperature of the first coil 310 from becoming too high. The first heat insulation flange 400b can block the heat of the magnetic sensing component 500 from being conducted to the second coil 320, thereby preventing the temperature of the second coil 320 from becoming too high.

[0112] Reference Figure 4 and Figure 9As shown, in some embodiments, the heat insulation element 400 may further include a second heat insulation flange 400c. Both the heat insulation pad 400a and the magnetic sensing element 500 may be annular. The second heat insulation flange 400c is connected to the inner side of the heat insulation pad 400a and extends toward the panel 100. In this way, the first heat insulation flange 400b can be blocked on the outer side of the magnetic sensing element 500, and the second heat insulation flange 400c can be blocked on the inner side of the magnetic sensing element 500, so that the heat of the magnetic sensing element 500 is concentrated and radiated to the cookware, thereby reducing the heat loss of the magnetic sensing element 500 and improving the heating efficiency of the magnetic sensing element 500.

[0113] Reference Figure 6 As shown, in one possible implementation, the first support 210 is provided with a plurality of ventilation openings 215, the ventilation openings 215 passing through both sides of the first support 210 along the axial direction of the first coil 310, and the plurality of ventilation openings 215 are arranged at intervals along the circumference of the first coil 310.

[0114] Thus, by setting a vent 215 on the first bracket 210, ventilation and heat dissipation are facilitated, and the heat of the coil assembly 300 is carried away by the air circulation, thereby helping to reduce the temperature of the coil assembly 300.

[0115] Reference Figure 1 and Figure 6 As shown, in one possible implementation, the housing may further include a bottom shell 700, and the coil disk may further include a connector. The panel 100 is connected to the bottom shell 700 to jointly define a receiving cavity, in which the coil disk is disposed. The first bracket 210 is also provided with a connecting hole 216, and the connector connects the bottom shell 700 and the connecting hole 216.

[0116] Thus, the receiving cavity can be used to house the coil, thereby improving the aesthetic appearance of the stove. Furthermore, the coil can be fixed inside the receiving cavity through the connection hole 216, improving the overall stability of the stove.

[0117] For example, the connector can be a threaded fastener, the bottom shell 700 can be provided with a threaded hole, the threaded fastener passes through the connecting hole 216 to be threadedly connected to the threaded hole, and the head of the threaded fastener is stopped on the side of the connecting hole 216 away from the threaded hole.
