Description

Technical Field

[0001] The present invention relates to the technical field of heating, and in particular, to an electromagnetic heating component and an electromagnetic heating device. Background Art

[0002] Electromagnetic heating has become a relatively mature heating technology at the present stage, and it is widely applied to electromagnetic heating devices such as induction cookers.

[0003] Among them, the working principle of electromagnetic heating is as Figure 1 shown. Specifically, an alternating current passes through a coil to generate a changing magnetic field. The changing magnetic field continuously cuts a ferromagnetic cookware, causing eddy currents to be generated in the cookware, such as eddy current I 流 . When the eddy current I 流 flows through a cookware with an internal resistance R, Joule heat Q is generated, and Q = I 流 2 Rt, where t is time. Under the action of this Joule heat Q, the cookware rapidly heats up, thereby achieving the heating of food.

[0004] In related technical solutions, as Figure 2 and Figure 3 shown, an electromagnetic heating coil 102', such as an enameled wire, is placed on one side of a bracket 104'. A magnetic strip 106' is arranged on the other side of the bracket 104'. A cookware 108' is placed on the upper side of the electromagnetic heating coil 102'.

[0005] However, the effective distance of electromagnetic heating is very short, such as within 5 cm. During daily cooking, when performing operations such as flipping the pan and lifting the pan, the cookware 108' cannot be heated because it is beyond the working distance range, which affects normal cooking. Summary of the Invention

[0006] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0007] To this end, in the first aspect of the present invention, an electromagnetic heating component is provided.

[0008] In the second aspect of the present invention, an electromagnetic heating device is provided.

[0009] In view of this, according to the first aspect of the present invention, an electromagnetic heating component is provided. The electromagnetic heating component has a working surface, and the electromagnetic heating component includes: a first electromagnetic heating coil, the first electromagnetic heating coil facing the working surface in the direction of wire lamination; a first magnetic member, arranged at an interval from the first electromagnetic heating coil; wherein, the N pole of the first magnetic member is close to the first electromagnetic heating coil, and the S pole of the first magnetic member is far from the first electromagnetic heating coil.

[0010] The present invention provides an electromagnetic heating component. In this electromagnetic heating component, the direction of the wire lamination of the first electromagnetic heating coil faces the working surface. When the side of the first electromagnetic heating coil close to the working surface is the N pole, the generated magnetic lines of force pass through the working surface and then act on the vessel, causing eddy currents in the vessel and thus achieving heating.

[0011] Since the N pole of the first magnetic member is close to the first electromagnetic heating coil, the side of the first electromagnetic heating coil close to the working surface repels the N pole of the first magnetic member, causing the magnetic lines of force emitted by the side of the first electromagnetic heating coil facing the working surface to rise upward in the direction of the magnetic lines of force generated by the N pole of the first magnetic member.

[0012] In this process, compared with the technical solution that only uses a single electromagnetic heating coil, the technical solution proposed by the present invention can increase the upward distance of the magnetic lines of force, increase the magnetic field strength, and at the same time increase the coverage area of the magnetic field, so as to achieve electromagnetic heating even when the vessel is far from the working surface.

[0013] At the same time, the side of the first electromagnetic heating coil facing away from the working surface is the S pole, which can form a closed curve with the upward magnetic lines of force of the N pole of the first magnetic member.

[0014] In this process, it is possible to reduce the electromagnetic leakage during the operation of the electromagnetic heating component, reduce the heating effect on the metal products located at the bottom of the electromagnetic heating component, and thus reduce the probability of fire, thereby improving the safety of the electromagnetic heating component.

[0015] In some technical solutions, the working surface can be understood as a plane for placing the vessel, such as a panel.

[0016] In some technical solutions, the direction of the wire lamination of the first electromagnetic heating coil can be understood as the axial direction around which the first electromagnetic heating coil is wound.

[0017] In some technical solutions, the direction of the wire lamination of the first electromagnetic heating coil can be understood as the direction from the S pole to the N pole of the first electromagnetic heating coil.

[0018] In some technical solutions, the first magnetic member can be a magnetic strip.

[0019] In addition, the electromagnetic heating component proposed in this application also has the following additional technical features.

[0020] In some technical solutions, optionally, the number of the first magnetic members is N, and the N first magnetic members are spaced apart and distributed in the circumferential direction of the first electromagnetic heating coil; N is a positive integer greater than or equal to 2.

[0021] In this technical solution, by arranging a plurality of first magnetic members, the number of magnetic field lines emitted towards the working surface is increased, thereby enhancing the magnetic field intensity at the position of the working surface, and further improving the heating efficiency.

[0022] In addition, since the N first magnetic members are arranged in the circumferential direction of the first electromagnetic heating coil, therefore, it can almost entirely enhance the upward distance of the magnetic field lines emitted from one end of the first electromagnetic heating coil close to the working surface, thereby increasing the magnetic field coverage range of the electromagnetic heating assembly and improving the efficiency of electromagnetic heating.

[0023] In some technical solutions, N is 2, 3 or 4.

[0024] In some technical solutions, optionally, it further includes: a second electromagnetic heating coil, the second electromagnetic heating coil facing the working surface in the direction of wire lamination; a second magnetic member, arranged at an interval from the second electromagnetic heating coil; wherein, when the second electromagnetic heating coil is energized, and the side of the first electromagnetic heating coil close to the working surface is the N pole, and the side of the second electromagnetic heating coil close to the working surface is the S pole, the S pole of the first magnetic member is close to the second electromagnetic heating coil, the N pole of the second magnetic member is close to the first electromagnetic heating coil, and the S pole of the second magnetic member is close to the second electromagnetic heating coil; or when the second electromagnetic heating coil is energized, and the side of the first electromagnetic heating coil close to the working surface is the S pole, and the side of the second electromagnetic heating coil close to the working surface is the N pole, the N pole of the first magnetic member is close to the second electromagnetic heating coil, the S pole of the second magnetic member is close to the first electromagnetic heating coil, and the N pole of the second magnetic member is close to the second electromagnetic heating coil.

[0025] In this technical solution, by arranging the second electromagnetic heating coil and the second magnetic member, so that the first electromagnetic heating coil, the second electromagnetic heating coil, the first magnetic member and the second magnetic member form a heating unit.

[0026] During this process, the first electromagnetic heating coil, the second electromagnetic heating coil, the first magnetic member and the second magnetic member are distributed in a ring-shaped and staggered manner.

[0027] During this process, the heating efficiency of the electromagnetic heating assembly can be improved.

[0028] Specifically, if the side of the first electromagnetic heating coil close to the working surface is the N pole, and the side of the second electromagnetic heating coil close to the working surface is the S pole, then the N poles of the first magnetic member and the second magnetic member are close to the N pole of the first electromagnetic heating coil, so that the magnetic field lines emitted from the N pole of the first electromagnetic heating coil are lifted under the action of the first magnetic member and the second magnetic member. Similarly, the S pole of the second electromagnetic heating coil repels the S poles of the first magnetic member and the second magnetic member, so that the magnetic field lines flowing back to the S pole of the second electromagnetic heating coil are lifted.

[0029] During this process, after the magnetic lines of force emitted from the N pole of the first electromagnetic heating coil rise, a closed curve is formed with the S pole of the second electromagnetic heating coil. Obviously, the magnetic lines of force in this closed curve are all lifted through the action of the first magnetic part and the second magnetic part. Therefore, the coverage range of the magnetic fields generated by the first electromagnetic heating coil and the second electromagnetic heating coil will increase, enabling the cookware to be heated even when it is at a relatively far distance from the first electromagnetic heating coil and the second electromagnetic heating coil. Thus, it overcomes the problem in the related technical solutions that when the cookware is flipped or lifted in other operations, it cannot be heated when it exceeds the working distance range, thereby improving the cooking experience.

[0030] When the second electromagnetic heating coil is energized and the side of the first electromagnetic heating coil close to the working surface is the S pole, and the side of the second electromagnetic heating coil close to the working surface is the N pole, its working state is similar to the case where the side of the first electromagnetic heating coil close to the working surface is the N pole and the side of the second electromagnetic heating coil close to the working surface is the S pole. The difference is that the magnetic lines of force generated on the side of the second electromagnetic heating coil close to the working surface return to the side of the first electromagnetic heating coil close to the working surface after rising.

[0031] In some technical solutions, optionally, it further includes: a bracket; the first electromagnetic heating coil and / or the first magnetic part is arranged on the bracket.

[0032] In this technical solution, by setting the bracket, the fixation of one of the first electromagnetic heating coil and the first magnetic part can be realized by using the bracket, or the fixation of all can be realized. During this process, the situation that at least one of the first electromagnetic heating coil and the first magnetic part deviates from its original position due to poor fixation can be reduced, thereby affecting the heating efficiency of the electromagnetic heating component.

[0033] In some technical solutions, optionally, the first electromagnetic heating coil is arranged on the bracket.

[0034] In some technical solutions, optionally, the first magnetic part is arranged on the bracket.

[0035] In some technical solutions, optionally, the first electromagnetic heating coil and the first magnetic part are arranged on the bracket.

[0036] In some technical solutions, the bracket has an installation groove, and the first electromagnetic heating coil and / or the first magnetic part is arranged in the installation groove.

[0037] In some technical solutions, the bracket has heat dissipation holes, and the heat dissipation holes are arranged opposite to the first electromagnetic heating coil.

[0038] In this technical solution, by setting the heat dissipation holes, the first electromagnetic heating coil can be dissipated heat, thereby reducing the probability of damage to the first electromagnetic heating coil due to excessive temperature, and thus improving the use safety of the electromagnetic heating component.

[0039] In some technical solutions, optionally, when the electromagnetic heating component includes a second electromagnetic heating coil and a second magnetic member, the second electromagnetic heating coil and / or the second magnetic member are disposed on the bracket.

[0040] In this technical solution, by disposing at least one of the second electromagnetic heating coil and the second magnetic member on the bracket, it is possible to reduce the detachment of at least one of the second electromagnetic heating coil and the second magnetic member from its original position due to poor fixation, thereby affecting the heating efficiency of the electromagnetic heating component.

[0041] In some technical solutions, optionally, the first electromagnetic heating coil, the first magnetic member, the second electromagnetic heating coil, and the second magnetic member are disposed on the same mounting surface of the bracket.

[0042] In this technical solution, by disposing the first electromagnetic heating coil, the first magnetic member, the second electromagnetic heating coil, and the second magnetic member on the same mounting surface of the bracket, it is possible to make the magnetic field formed by the first electromagnetic heating coil and the first magnetic member similar to the magnetic field constructed by the second electromagnetic heating coil and the second magnetic member, thereby improving the heating uniformity of the cookware placed on the working surface.

[0043] In some technical solutions, the bracket has a first mounting surface facing the working surface and a second mounting surface facing away from the working surface.

[0044] In some technical solutions, the first electromagnetic heating coil, the first magnetic member, the second electromagnetic heating coil, and the second magnetic member are disposed on the first mounting surface or the second mounting surface of the bracket.

[0045] In some technical solutions, optionally, the first electromagnetic heating coil and / or the second electromagnetic heating coil is a coil wound in a spiral.

[0046] In this technical solution, the coil wound in a spiral can be an immediately spiral coil. By defining the first electromagnetic heating coil and the second electromagnetic heating coil as spiral coils, it is possible to increase the magnetic field strength of the electromagnetic heating component by increasing the number of coils, while increasing the heatable distance of the electromagnetic heating component and facilitating the increase of the heating power.

[0047] In some technical solutions, the first electromagnetic heating coil and / or the second electromagnetic heating coil is a concentric circle coil.

[0048] In some technical solutions, optionally, the electromagnetic heating component further includes: a shielding layer disposed on one side of the bracket and away from the working surface.

[0049] In this technical solution, the provided shielding layer is used to shield the leaked magnetic lines of force, thereby reducing the magnetic leakage amount and improving the safety of the electromagnetic heating component.

[0050] In some technical solutions, the shielding layer is an aluminum film.

[0051] According to the second aspect of the present invention, there is provided an electromagnetic heating device, including: the electromagnetic heating assembly according to any one of the above.

[0052] In some technical solutions, optionally, the working surface in the electromagnetic heating assembly is a panel.

[0053] In some technical solutions, optionally, the electromagnetic heating device includes one of the following: an induction cooker, an electric stove, a rice cooker, and an electric pressure cooker.

[0076] In order to be able to more clearly understand the above aspects, features and advantages of the present invention, the present invention will be further described in detail below in conjunction with the drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0077] Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0078] The Halbach Array is a magnet structure, which is an approximately ideal structure in engineering. The goal is to generate the strongest magnetic field with the smallest number of magnets. In 1979, when the American scholar Klaus Halbach was doing an electron acceleration experiment, he discovered this special permanent magnet structure and gradually improved it, and finally formed the so-called "Halbach" magnet.

[0079] As Figure 4 and Figure 5 shown, the Halbach Array forms a single-sided strong magnetic field through the arrangement of magnets. Four magnets are grouped together, and the magnetic field on the back is maximally suppressed. On the front of the array, the physical distance between the N and S poles is relatively far. The magnetic field needs to pass through a longer path from the N pole to the S pole, causing all the magnetic lines of force to spread upward. And at the lower part of the array, since the longitudinal coil and the N and S poles of the transverse magnet are relatively close, the magnetic lines of force quickly enter the S pole of the longitudinal coil from the N pole of the transverse magnet to form a closed loop.

[0080] In an embodiment of the present application, as Figure 6 , Figure 7 and Figure 8 shown, an electromagnetic heating component is provided. The electromagnetic heating component has a working surface 100. The electromagnetic heating component includes: a first electromagnetic heating coil 102, and the first electromagnetic heating coil 102 faces the working surface 100 in the direction of the wire lamination; a first magnetic member 104, which is arranged at an interval from the first electromagnetic heating coil 102; wherein, the N pole of the first magnetic member 104 is close to the first electromagnetic heating coil 102, and the S pole of the first magnetic member 104 is far from the first electromagnetic heating coil 102.

[0081] The present invention proposes an electromagnetic heating component. In this electromagnetic heating component, the direction of the wire lamination of the first electromagnetic heating coil 102 faces the working surface 100. When the side of the first electromagnetic heating coil 102 close to the working surface 100 is the N pole, the generated magnetic lines of force pass through the working surface 100, and then act on the utensil, causing eddy currents in the utensil, and thus realizing heating.

[0082] Since the N pole of the first magnetic member 104 is close to the first electromagnetic heating coil 102, therefore, the side of the first electromagnetic heating coil 102 close to the working surface 100 repels the N pole of the first magnetic member 104, causing the magnetic lines of force emitted by the side of the first electromagnetic heating coil 102 facing the working surface 100 to rise upward in the direction of the magnetic lines of force generated by the N pole of the first magnetic member 104.

[0083] During this process, compared with the embodiment that only uses a single electromagnetic heating coil, the embodiment proposed by the present invention can increase the upward distance of the magnetic field lines, increase the magnetic field strength, and increase the coverage range of the magnetic field, so as to achieve electromagnetic heating even when the vessel is far from the working surface 100 by 100.

[0084] At the same time, the side of the first electromagnetic heating coil 102 facing away from the working surface 100 is the S pole, which can form a closed curve with the magnetic field lines rising from the N pole of the first magnetic member 104.

[0085] During this process, the electromagnetic leakage during the operation of the electromagnetic heating component can be reduced, and the heating effect on the metal products located at the bottom of the electromagnetic heating component can be reduced, thereby reducing the probability of fire and improving the safety of the electromagnetic heating component.

[0086] In some embodiments, the working surface 100 can be understood as a plane for placing vessels, such as a panel.

[0087] In some embodiments, the direction in which the wire layers of the first electromagnetic heating coil 102 are stacked can be understood as the axial direction around which the first electromagnetic heating coil 102 is wound.

[0088] In some embodiments, the direction in which the wire layers of the first electromagnetic heating coil 102 are stacked can be understood as the direction from the S pole to the N pole of the first electromagnetic heating coil 102.

[0089] In some embodiments, the first magnetic member 104 can be a magnetic strip.

[0090] In addition, the electromagnetic heating component proposed in this application also has the following additional technical features.

[0091] In some embodiments, optionally, the number of the first magnetic members 104 is N, and the N first magnetic members 104 are spaced apart and distributed in the circumferential direction of the first electromagnetic heating coil 102; N is a positive integer greater than or equal to 2.

[0092] In this embodiment, by arranging a plurality of first magnetic members 104, the number of magnetic field lines emitted to the working surface 100 is increased, thereby enhancing the magnetic field strength at the position where the working surface 100 is located, and further improving the heating efficiency.

[0093] In addition, since the N first magnetic members 104 are arranged in the circumferential direction of the first electromagnetic heating coil 102, they can almost all enhance the upward distance of the magnetic field lines emitted from one end of the first electromagnetic heating coil 102 close to the working surface 100, thereby increasing the magnetic field coverage range of the electromagnetic heating component and improving the efficiency of electromagnetic heating.

[0094] Exemplarily, if N is 3, the positional relationship between the first magnetic member 104 and the first electromagnetic heating coil 102 is asFigure 9 and Figure 10 as shown

[0095] Exemplarily, when N is 4, the positional relationship between the first magnetic member 104 and the first electromagnetic heating coil 102 is as shown Figure 11 and Figure 12 as shown

[0096] In some embodiments, optionally, as shown Figure 13 , Figure 14 , Figure 15 and Figure 16 shown, further comprising: a second electromagnetic heating coil 106, the second electromagnetic heating coil 106 facing the working surface 100 in the direction of wire lamination; a second magnetic member 108, spaced apart from the second electromagnetic heating coil 106; wherein, when the second electromagnetic heating coil 106 is energized and the side of the first electromagnetic heating coil 102 close to the working surface 100 is the N pole, and the side of the second electromagnetic heating coil 106 close to the working surface 100 is the S pole, the S pole of the first magnetic member 104 is close to the second electromagnetic heating coil 106, the N pole of the second magnetic member 108 is close to the first electromagnetic heating coil 102, and the S pole of the second magnetic member 108 is close to the second electromagnetic heating coil 106; or when the second electromagnetic heating coil 106 is energized and the side of the first electromagnetic heating coil 102 close to the working surface 100 is the S pole, and the side of the second electromagnetic heating coil 106 close to the working surface 100 is the N pole, the N pole of the first magnetic member 104 is close to the second electromagnetic heating coil 106, the S pole of the second magnetic member 108 is close to the first electromagnetic heating coil 102, and the N pole of the second magnetic member 108 is close to the second electromagnetic heating coil 106.

[0097] In this embodiment, by providing the second electromagnetic heating coil 106 and the second magnetic member 108, so that the first electromagnetic heating coil 102, the second electromagnetic heating coil 106, the first magnetic member 104 and the second magnetic member 108 form a heating unit.

[0098] During this process, the first electromagnetic heating coil 102, the second electromagnetic heating coil 106, the first magnetic member 104 and the second magnetic member 108 are annularly and alternately distributed.

[0099] During this process, the heating efficiency of the electromagnetic heating assembly can be improved.

[0100] Specifically, the side of the first electromagnetic heating coil 102 close to the working surface 100 is the N pole, and the side of the second electromagnetic heating coil 106 close to the working surface 100 is the S pole. Then, the N poles of the first magnetic member 104 and the second magnetic member 108 are close to the N pole of the first electromagnetic heating coil 102, so that the magnetic lines of force emitted by the N pole of the first electromagnetic heating coil 102 rise under the action of the first magnetic member 104 and the second magnetic member 108. Similarly, the S pole of the second electromagnetic heating coil 106 repels the S poles of the first magnetic member 104 and the second magnetic member 108, causing the magnetic lines of force flowing back to the S pole of the second electromagnetic heating coil 106 to rise.

[0101] During this process, after the magnetic lines of force emitted by the N pole of the first electromagnetic heating coil 102 rise, a closed curve is formed with the S pole of the second electromagnetic heating coil 106. Obviously, the magnetic lines of force in this closed curve all rise under the action of the first magnetic member 104 and the second magnetic member 108. Therefore, the coverage range of the magnetic fields generated by the first electromagnetic heating coil 102 and the second electromagnetic heating coil 106 will increase, enabling the pot body to be heated even when it is at a relatively far distance from the first electromagnetic heating coil 102 and the second electromagnetic heating coil 106. Thus, it overcomes the problem in related embodiments that during the operation of flipping the pot or other operations of lifting the pot, when the distance exceeds the working distance range, the pot cannot be heated, thereby improving the cooking experience.

[0102] When the second electromagnetic heating coil 106 is energized, and the side of the first electromagnetic heating coil 102 close to the working surface 100 is the S pole, and the side of the second electromagnetic heating coil 106 close to the working surface 100 is the N pole, its working state is similar to the case where the side of the first electromagnetic heating coil 102 close to the working surface 100 is the N pole and the side of the second electromagnetic heating coil 106 close to the working surface 100 is the S pole. The difference is that the magnetic lines of force generated on the side of the second electromagnetic heating coil 106 close to the working surface 100 flow back to the side of the first electromagnetic heating coil 102 close to the working surface 100 after rising.

[0103] In some embodiments, optionally, it further includes: a bracket 110; the first electromagnetic heating coil 102 and / or the first magnetic member 104 is / are arranged on the bracket 110.

[0104] In this embodiment, by providing the bracket 110, the bracket 110 can be used to fix one of the first electromagnetic heating coil 102 and the first magnetic member 104, or to fix all of them. During this process, it can reduce the detachment of at least one of the first electromagnetic heating coil 102 and the first magnetic member 104 from its original position due to poor fixation, thereby affecting the heating efficiency of the electromagnetic heating assembly.

[0105] In some embodiments, optionally, the first electromagnetic heating coil 102 is disposed on the bracket 110.

[0106] In some embodiments, optionally, the first magnetic member 104 is disposed on the bracket 110.

[0107] In some embodiments, optionally, the first electromagnetic heating coil 102 and the first magnetic member 104 are disposed on the bracket 110.

[0108] In some embodiments, the bracket 110 has a mounting groove, and the first electromagnetic heating coil 102 and / or the first magnetic member 104 is disposed in the mounting groove.

[0109] In some embodiments, the bracket 110 has heat dissipation holes, and the heat dissipation holes are disposed opposite to the first electromagnetic heating coil 102.

[0110] In this embodiment, by providing the heat dissipation holes, the first electromagnetic heating coil 102 can be dissipated, thereby reducing the probability of damage to the first electromagnetic heating coil 102 due to excessive temperature, thereby improving the use safety of the electromagnetic heating component.

[0111] In some embodiments, optionally, in the case where the electromagnetic heating component includes the second electromagnetic heating coil 106 and the second magnetic member 108, the second electromagnetic heating coil 106 and / or the second magnetic member 108 is disposed on the bracket 110.

[0112] In this embodiment, by disposing at least one of the second electromagnetic heating coil 106 and the second magnetic member 108 on the bracket 110, at least one of the second electromagnetic heating coil 106 and the second magnetic member 108 is prevented from being displaced from its original position due to poor fixation, thereby affecting the heating efficiency of the electromagnetic heating component.

[0113] In some embodiments, optionally, the first electromagnetic heating coil 102, the first magnetic member 104, the second electromagnetic heating coil 106, and the second magnetic member 108 are disposed on the same mounting surface of the bracket 110.

[0114] In this embodiment, by disposing the first electromagnetic heating coil 102, the first magnetic member 104, the second electromagnetic heating coil 106, and the second magnetic member 108 on the same mounting surface of the bracket 110, the magnetic field formed by the first electromagnetic heating coil 102 and the first magnetic member 104 can be made similar to the magnetic field constructed by the second electromagnetic heating coil 106 and the second magnetic member 108, thereby improving the heating uniformity of the pot body placed on the working surface 100.

[0115] In some embodiments, the bracket 110 has a first mounting surface facing the working surface 100 and a second mounting surface facing away from the working surface 100.

[0116] In some embodiments, the first electromagnetic heating coil 102, the first magnetic member 104, the second electromagnetic heating coil 106, and the second magnetic member 108 are disposed on the first mounting surface or the second mounting surface of the bracket 110.

[0117] In some embodiments, optionally, the first electromagnetic heating coil 102 and / or the second electromagnetic heating coil 106 is a coil wound in a spiral.

[0118] In this embodiment, the coil wound in a spiral may immediately be a spiral coil. By defining the first electromagnetic heating coil 102 and the second electromagnetic heating coil 106 as spiral coils, the magnetic field strength of the electromagnetic heating assembly can be increased by increasing the number of coils. While increasing the heatable distance of the electromagnetic heating assembly, it is also convenient to increase the heating power.

[0119] In some embodiments, the first electromagnetic heating coil 102 and / or the second electromagnetic heating coil 106 is a concentric circle coil.

[0120] In some embodiments, optionally, the electromagnetic heating assembly further includes: a shielding layer 112, disposed on one side of the bracket 110 and away from the working surface 100.

[0121] In this embodiment, the provided shielding layer 112 is used to shield the leaked magnetic lines of force, thereby reducing the magnetic leakage amount, so as to improve the safety of the electromagnetic heating assembly.

[0122] In some embodiments, the shielding layer 112 is an aluminum film.
