[0001] The present invention relates to the technical field of heating components, and in particular to a coil disk, a coil disk control method, a coil disk control device, a readable storage medium and a heating component. Background Art
[0002] At present, electromagnetic heating components such as induction cookers are provided with electromagnetic coils, which can heat appliances placed on the induction cookers. However, heating appliances with electromagnetic coils requires the appliances to be magnetic, and heating cannot be achieved for non-magnetic appliances.
[0003] In the related art, in order to enable an induction cooker to heat non-magnetic appliances, an electromagnetic coil is combined with a resistance wire, for example, a layer of electromagnetic wire is coated on the outside of the resistance wire, or a layer of resistance wire is coated on the outside of the electromagnetic wire, so that the non-magnetic appliance can be heated by the resistance wire, and the magnetic appliance can be heated by the electromagnetic coil. However, this type of coil requires the electromagnetic coil and the resistance wire to be manufactured in combination, which makes the manufacturing process of the coil more complicated and the cost of the coil higher. Summary of the invention
[0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.
[0005] To this end, a first aspect of the present invention provides a coil disk.

[0008] A fourth aspect of the present invention provides a control device for a coil disk.
[0009] A fifth aspect of the present invention provides a readable storage medium.
[0010] A sixth aspect of the present invention provides a heating component.
[0011] In view of this, a first aspect of the present invention provides a coil disk, which includes a coil and a control module, wherein the control module is electrically connected to the coil, and the control module can adjust the frequency of the current passing through the coil to adjust the self-heating power and / or electromagnetic heating power of the coil.
[0012] The coil disk provided by the present invention can be used for a heating component, and the coil disk can heat an appliance placed on the heating component, or the coil disk can heat an appliance that needs to be heated and is provided by the heating component.
[0013] The coil disk includes a coil and a control module. The control module is electrically connected to the coil, and thus the operation of the coil can be controlled through the control module to achieve the driving of the coil. When the control module controls the operation of the coil, it adjusts the frequency of the current passing through the coil, thereby adjusting the self-heating power and / or electromagnetic heating power of the coil, so that the heating component can heat non-magnetic appliances through the self-heating heating mode, and the heating component can also perform electromagnetic heating on magnetic appliances through the electromagnetic heating mode, enriching the usage scenarios of the heating component and expanding the applicable range of the heating component. And by adjusting the frequency of the current in the coil to achieve the adjustment of the self-heating power and / or electromagnetic heating power of the coil, the coil no longer requires a composite resistance wire, thereby simplifying the manufacturing process of the coil, reducing the manufacturing difficulty of the coil, and further reducing the manufacturing cost of the coil.
[0014] By adjusting the frequency of the current in the coil to achieve the adjustment of the self-heating power and / or electromagnetic heating power of the coil, the part for realizing the electromagnetic heating of the coil and the part for realizing the self-heating of the coil are the same area of the coil, thereby improving the heating uniformity.
[0015] In addition, the coil disk in the above technical solution provided by the present invention may further have the following additional technical features:
[0016] In some technical solutions of the present invention, optionally, the coil includes a wire harness, and the wire harness is arranged in a spiral shape; wherein, the number of wire harnesses is one; and / or the number of wire harnesses is multiple, and multiple wire harnesses are arranged in parallel.
[0017] In this technical solution, the coil includes a wire harness, and the wire harness is arranged in a spiral shape. After the current passes through the wire harness, the wire harness can heat itself, thereby realizing infrared heating; the current passing through the wire harness can also generate a magnetic field, thereby realizing electromagnetic heating of magnetic appliances. The number of wire harnesses is one, and one wire harness is wound in a ring shape to form a coil. The number of wire harnesses can also be multiple, and multiple wire harnesses are arranged in parallel and wound in a spiral shape to form a coil.
[0018] In some technical solutions of the present invention, optionally, the coil includes a first conductive part and a second conductive part; the first conductive part is arranged in a spiral shape; the second conductive part covers the outside of the first conductive part and extends from the first end of the first conductive part to the second end of the first conductive part; wherein, the resistivity of the first conductive part is different from the resistivity of the second conductive part.
[0019] In this technical solution, the coil includes a first conductive part and a second conductive part. The first conductive part is arranged in a spiral shape, and the second conductive part covers the outside of the first conductive part, extending from the first end of the first conductive part to the second end of the first conductive part. Then, a wire harness is formed by the combination of the first conductive part and the second conductive part. Since the resistivity of the first conductive part is different from that of the second conductive part, the control component can flexibly control the coil according to the heating requirements of the coil. The coil can mainly use electromagnetic heating, mainly use infrared heating, or simultaneously use electromagnetic and infrared heating, improving the flexibility of controlling the coil and further expanding the applicable range of the heating component. Moreover, because the resistivity of the first conductive part is different from that of the second conductive part, when controlling the heating of the coil, the heating mode of the coil can be better controlled according to the characteristics of the change in the coil resistance, improving the accuracy of controlling the coil.
[0020] Further, the resistivity of the first conductive part is less than that of the second conductive part.
[0021] The frequency of the current passing through the coil is the third frequency, and the self-heating power of the coil is greater than the electromagnetic heating power of the coil; the frequency of the current in the coil is the fourth frequency, and the self-heating power of the coil is less than the electromagnetic heating power of the coil; the third frequency is greater than the fourth frequency.
[0022] Further, the resistivity of the first conductive part is greater than that of the second conductive part;
[0023] The frequency of the current in the coil is the fifth frequency, and the self-heating power of the coil is less than the electromagnetic heating power of the coil; the frequency of the current in the coil is the sixth frequency, and the self-heating power of the coil is greater than the electromagnetic heating power of the coil; the fifth frequency is greater than the sixth frequency.
[0024] In some technical solutions of the present invention, optionally, the resistivity of the coil increases or decreases from the first end of the coil to the second end of the coil.
[0025] In this technical solution, the resistivity of the coil increases or decreases from the first end of the coil to the second end of the coil, resulting in a non-uniform distribution of the resistivity of the coil. Then, the control component can flexibly control the coil according to the heating requirements of the coil. The coil can mainly use electromagnetic heating, mainly use infrared heating, or simultaneously use electromagnetic and infrared heating, improving the flexibility of controlling the coil and further expanding the applicable range of the heating component. Moreover, because the resistivity of the coil increases or decreases from the first end of the coil to the second end of the coil, when controlling the heating of the coil, the heating mode of the coil can be better controlled according to the characteristics of the change in the coil resistance, improving the accuracy of controlling the coil.
[0026] In some technical solutions of the present invention, optionally, the resistivity of the coil increases or decreases from the center of the coil to the outside along the radial direction of the cross-section of the coil, or the resistivity of the coil increases or decreases from the center of the coil to the outside along the radial direction of the coil.
[0027] In this technical solution, the resistivity of the coil increases or decreases from the center of the coil to the outside along the radial direction of the coil or the cross-section of the coil, so that the resistivity of the coil is not evenly distributed. As a result, the control component can flexibly control the coil according to the heating requirements of the coil. The coil can mainly use electromagnetic heating, mainly use infrared heating, or simultaneously use electromagnetic and infrared heating, improving the flexibility of controlling the coil and further expanding the application range of the heating component. And because the resistivity of the coil increases or decreases from the center of the coil to the outside along the radial direction of the coil, when controlling the heating of the coil, the heating mode of the coil can be better controlled according to the characteristics of the change in the coil resistance, improving the accuracy of controlling the coil.
[0028] In some technical solutions of the present invention, optionally, the cross-sectional shape of the coil is rectangular, circular, triangular, pentagonal or hexagonal.
[0029] In this technical solution, the cross-sectional shape of the coil is rectangular or triangular. The rectangular coil can effectively reduce the deformation generated after the coil heats up, thereby reducing the probability of contact between two adjacent rows of coils and improving the stability of the coil during operation.
[0030] When the cross-sectional shape of the coil is circular, it can effectively reduce the manufacturing cost of the coil, thereby reducing the overall cost of the heating component.
[0031] When the cross-sectional shape of the coil is pentagonal or hexagonal, while enhancing the strength of the coil itself, it makes the heating of the coil more uniform.
[0032] In some technical solutions of the present invention, optionally, the resistivity of the coil is less than or equal to 10 -6 ohm·m.
[0033] In this technical solution, the resistivity of the coil is less than or equal to 10 -6 ohm·m. As a result, the coil can change its heating state by adjusting the current frequency, enabling the coil to achieve self-heating, that is, heating the appliance placed on the heating component by infrared heating, or heating the appliance placed on the heating component by electromagnetic heating, further expanding the application range of the heating component.
[0034] Furthermore, the resistivity of the coil is greater than or equal to 10 -10 ohm·m.
[0035] Furthermore, the resistivity of the coil can be 10 -7 ohm·m.
[0036] The resistivity of the coil can also be 10 -8 ohm·m.
[0037] The resistivity of the coil can also be 10 -9 ohm·m.
[0038] The second aspect of the present invention provides a control method for a coil disk, including: in response to a cooking instruction, driving the coil to work; adjusting the frequency of the current passing through the coil to adjust the self-heating power and / or electromagnetic heating power of the coil.
[0039] The control method for the coil disk provided by the present invention, in response to a cooking instruction, drives the coil to work, adjusts the frequency of the current passing through the coil to adjust the self-heating power and / or electromagnetic heating power of the coil, so that the heating component can heat non-magnetic utensils through the self-heating heating mode, and the heating component can also perform electromagnetic heating on magnetic utensils through the electromagnetic heating mode, enriching the usage scenarios of the heating component and expanding the applicable range of the heating component. And by adjusting the frequency of the current of the coil to adjust the self-heating power and / or electromagnetic heating power of the coil, the coil no longer requires a composite resistance wire, thereby simplifying the manufacturing process of the coil, reducing the manufacturing difficulty of the coil, and further reducing the manufacturing cost of the coil.
[0040] By adjusting the frequency of the current of the coil to adjust the self-heating power and / or electromagnetic heating power of the coil, the part for realizing the electromagnetic heating of the coil and the part for realizing the self-heating of the coil are the same area of the coil, thereby improving the heating uniformity.
[0041] Further, by adjusting the frequency of the current flowing through the coil, the distribution of the current in the coil is realized, so as to adjust the proportion of the electromagnetic heating power and the infrared heating power. That is, by adjusting the frequency of the current, the adjustment of the heating mode of the coil is realized.
[0042] In addition, the coil disk in the above technical solution provided by the present invention may further have the following additional technical features:
[0043] In some technical solutions of the present invention, optionally, adjusting the frequency of the current passing through the coil to adjust the self-heating power and / or electromagnetic heating power of the coil includes: adjusting the frequency of the current passing through the coil to a first frequency so that the self-heating power of the coil is greater than the electromagnetic heating power of the coil; adjusting the frequency of the current passing through the coil to a second frequency so that the self-heating power of the coil is less than the electromagnetic heating power of the coil; the first frequency is greater than the second frequency.
[0044] In this technical solution, the frequency of the current passing through the coil is adjusted to a relatively large first frequency, so that the resistance of the coil increases, and more electrical energy of the current passing through the coil is converted into heat energy. Furthermore, the self-heating power of the coil is greater than the electromagnetic heating power of the coil, realizing the heating of weakly magnetic or non-magnetic utensils by infrared heating. The frequency of the current passing through the coil is adjusted to a relatively low second frequency, so that the resistance of the coil decreases, and more electromagnetic energy is generated by the current passing through the coil. Furthermore, the self-heating power of the coil is less than the electromagnetic heating power of the coil, realizing the heating of magnetic utensils by electromagnetic heating.
[0045] The heating component can adjust the frequency of the current passing through the coil through a high-frequency inverter circuit, thereby realizing the adjustment of the coil resistance.

[0047] Adjusting the frequency of the current passing through the coil to adjust the self-heating power and / or electromagnetic heating power of the coil includes: adjusting the frequency of the current passing through the coil to a third frequency so that the self-heating power of the coil is greater than the electromagnetic heating power of the coil; adjusting the frequency of the current passing through the coil to a fourth frequency so that the self-heating power of the coil is less than the electromagnetic heating power of the coil; the third frequency is greater than the fourth frequency.
[0048] In this technical solution, the coil includes a first conductive part and a second conductive part, and the resistivity of the first conductive part is less than that of the second conductive part.
[0049] When infrared heating is required, using the skin effect, the frequency of the current passing through the coil is increased, that is, the frequency of the current passing through the coil is adjusted to a relatively large third frequency, so that the current is more concentrated in the second conductive part with a greater resistivity, and the self-heating power of the coil is greater than the electromagnetic heating power of the coil. Furthermore, the infrared heating of the utensil is realized by the self-heating of the second conductive part.
[0050] When electromagnetic heating is required, the frequency of the current passing through the coil is reduced, that is, the frequency of the current passing through the coil is adjusted to a relatively small fourth frequency, so that the current density passing through the first conductive part with a smaller resistivity increases, and the self-heating power of the coil is less than the electromagnetic heating power of the coil. The electromagnetic heating of the utensil is realized by using a current with a relatively low frequency passing through the first conductive part.
[0051] In some technical solutions of the present invention, optionally, the coil includes a first conductive part and a second conductive part, and the resistivity of the first conductive part is greater than that of the second conductive part.
[0052] Adjusting the frequency of the current passing through the coil to adjust the self-heating power and / or electromagnetic heating power of the coil includes: adjusting the frequency of the current passing through the coil to a fifth frequency so that the self-heating power of the coil is less than the electromagnetic heating power of the coil; adjusting the frequency of the current passing through the coil to a sixth frequency so that the self-heating power of the coil is greater than the electromagnetic heating power of the coil; the fifth frequency is greater than the sixth frequency.
[0053] In this technical solution, the coil includes a first conductive part and a second conductive part, and the resistivity of the first conductive part is greater than that of the second conductive part.
[0054] When electromagnetic heating is required, increase the frequency of the current passing through the coil, that is, adjust the frequency of the current passing through the coil to the fifth frequency, so that the current is more concentrated in the second conductive part with a smaller resistivity, and the self-heating power of the coil is less than the electromagnetic heating power of the coil, and then electromagnetic heating of the appliance is realized through the second conductive part with a smaller resistivity.
[0055] When infrared heating is required, reduce the frequency of the current passing through the coil, that is, adjust the frequency of the current passing through the coil to the sixth frequency, so that the current density passing through the first conductive part with a larger resistivity increases, and the self-heating power of the coil is greater than the electromagnetic heating power of the coil, and then infrared heating of the appliance is realized through the first conductive part with a larger resistivity.
[0056] In some technical solutions of the present invention, optionally, adjusting the frequency of the current passing through the coil to adjust the self-heating power and / or electromagnetic heating power of the coil includes: adjusting the resistance value of the coil based on the frequency of the current passing through the coil; adjusting the self-heating power and / or electromagnetic heating power of the coil based on the resistance value of the coil.
[0057] In this technical solution, the resistance value of the coil is adjusted by adjusting the current frequency, and then the adjustment of the self-heating power and / or electromagnetic heating power of the coil is realized, so that the same coil can be used to realize both infrared heating and electromagnetic heating, which improves the application range of the heating component and reduces the manufacturing cost of the coil at the same time.
[0058] The third aspect of the present invention provides a control device for a coil disk, including a driving unit and an adjusting unit. The driving unit is used to drive the coil to work in response to a cooking instruction; the adjusting unit is used to adjust the frequency of the current passing through the coil to adjust the self-heating power and / or electromagnetic heating power of the coil.
[0059] The control device of the coil disk provided by the present invention responds to a cooking instruction, drives the coil to work, and adjusts the frequency of the current passing through the coil, so as to adjust the self-heating power and / or electromagnetic heating power of the coil, so that the heating component can heat a non-magnetic utensil through the self-heating heating mode, and the heating component can also perform electromagnetic heating on a magnetic utensil through the electromagnetic heating mode, enriching the usage scenarios of the heating component and improving the applicable range of the heating component. And by adjusting the frequency of the current of the coil, the self-heating power and / or electromagnetic heating power of the coil are adjusted, so that the coil no longer needs a composite resistance wire, thereby simplifying the manufacturing process of the coil, reducing the manufacturing difficulty of the coil, and further reducing the manufacturing cost of the coil.

[0078] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.
[0079] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention may be practiced in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited by the specific embodiments disclosed below.
[0080] The following refers to Figures 1 to 9 Describe a coil disk 100, a control method of the coil disk, a control device of the coil disk, a readable storage medium, and a heating component according to some embodiments of the present invention.
[0081] In an embodiment of the present invention, as Figure 1 and Figure 2 shown, a coil disk 100 is provided. The coil disk 100 includes a coil 110 and a control module 120. The control module 120 is electrically connected to the coil 110. The control module 120 can adjust the frequency of the current passing through the coil 110 to adjust the self-heating power and / or electromagnetic heating power of the coil 110.
[0082] In this embodiment, the coil disk 100 can be used for a heating component. The coil disk 100 can heat an appliance 300 placed on the heating component, or the coil disk 100 can heat the appliance 300 that the heating component itself needs to heat.
[0083] The coil disk 100 includes a coil 110 and a control module 120. The control module 120 is electrically connected to the coil 110. Thus, the coil 110 can be controlled to work through the control module 120 to realize the driving of the coil 110. When the control module 120 controls the coil 110 to work, it adjusts the frequency of the current passing through the coil 110, and then adjusts the self-heating power and / or electromagnetic heating power of the coil 110, so that the heating component can heat a non-magnetic appliance 300 through the self-heating mode, and the heating component can also perform electromagnetic heating on the magnetic appliance 300 through the electromagnetic heating mode, enriching the usage scenarios of the heating component and improving the applicable range of the heating component. And by adjusting the frequency of the current of the coil 110 to realize the adjustment of the self-heating power and / or electromagnetic heating power of the coil 110, the coil 110 no longer needs a composite resistance wire, thereby simplifying the manufacturing process of the coil 110, reducing the manufacturing difficulty of the coil 110, and further reducing the manufacturing cost of the coil 110.
[0084] By adjusting the frequency of the current of the coil 110 to realize the adjustment of the self-heating power and / or electromagnetic heating power of the coil 110, the part for realizing the electromagnetic heating of the coil 110 and the part for realizing the self-heating of the coil 110 are the same area of the coil 110, thereby improving the heating uniformity.
[0085] Further, when heating the magnetic appliance 300 through the heating component, by adjusting the frequency of the current in the coil 110, the coil 110 mainly performs electromagnetic heating and supplemented by self-heating, thereby improving the heating efficiency of the appliance 300.
[0086] When heating the non-magnetic appliance 300 through the heating component, by adjusting the frequency of the current in the coil 110, the coil 110 mainly performs self-heating and supplemented by electromagnetic heating, thereby realizing the heating of the non-magnetic appliance 300, such as heating the stainless-steel appliance 300 or the ceramic appliance 300.
[0087] Specifically, based on the skin effect, proximity effect, and circular ring effect of high-frequency current in the conductor 400, etc., when the high-frequency current flows in the conductor 400, it can cause a change in the cross-sectional area of the conductor 400 through which the current conducts. That is, the self-heating power and / or electromagnetic heating power of the coil 110 can be adjusted by adjusting the current frequency of the coil 110.
[0088] For example, as Figure 3 shown, the skin effect is that when an alternating current passes through the conductor 400, the change in the current will generate a changing magnetic field around the conductor 400. According to Faraday's law of electromagnetic induction, this magnetic field will induce an electric field inside the conductor 400, thereby generating eddy currents. These eddy currents will generate a reverse magnetic field, and according to Ampere's circuital law, this reverse magnetic field will cancel the original magnetic field, thereby reducing the current inside the conductor 400. Since the current is mainly concentrated on the surface of the conductor 400, the current density on the surface of the conductor 400 will be much larger than that inside, thus generating the skin effect. The skin effect can also be explained by the process of electromagnetic wave penetration into the conductor 400. When the electromagnetic wave penetrates into the conductor 400, it gradually attenuates due to energy loss. When the wave amplitude attenuates to a certain multiple of the surface wave amplitude, the depth is called the penetration depth of the alternating electromagnetic field into the conductor 400. Taking the penetration of a plane electromagnetic wave into a semi-infinite conductor 400 as an example, the penetration depth δ is:
[0089]
[0090] In the above equation ①, f is the frequency, γ is the conductivity of the conductor 400, and μ is the magnetic permeability. As Figure 4 shown, if the conductor 400 is a cylinder and the high-frequency current flows along the axial direction of the cylindrical conductor 400, that is, the high-frequency current flows along the length direction of the cylindrical conductor 400. In a cross-section of the cylindrical conductor 400, the current density in the region near the edge of the cross-section is relatively large, and the current density in the region near the center of the cross-section is relatively small, that is, the current density in the region near the edge of the cross-section is greater than the current density in the region near the center of the cross-section.
[0091] On this basis, the expression of resistance is:
[0092] R = ρ × L / S; ②
[0093] In the above equation ②, R is the resistance value of the conductor 400, ρ is the resistivity of the conductor 400, L is the length of the conductor 400, and S is the area of the conductor 400.
[0094] It can be seen from the expression of the skin depth (the above equation ①) that the conduction area of the conductor 400 gradually decreases as the frequency of the current flowing through it increases. Combining with the resistance expression (the above equation ②), that is, the greater the current frequency flowing through the conductor 400, the greater the resistance of the conductor 400. Therefore, by changing the frequency of the current, the resistance value of the coil 110 can be adjusted, that is, the self-heating power of the coil 110 can be adjusted by adjusting the frequency.
[0095] As Figure 4 shown, the current in the conductor 400 can flow in the direction shown by arrow A or in the direction shown by arrow B.
[0096] The self-heating of the coil 110 is that the coil 110 heats the appliance 300 by infrared heating.
[0097] Furthermore, the heating component can be an induction cooker. The induction cooker is provided with a panel 200, the coil disk 100 is located below the panel 200, and the appliance 300 can be placed on the panel 200.
[0098] The panel 200 can be a microcrystalline panel 200.
[0099] The appliance 300 can be a cookware, and the appliance 300 can also be other carriers to be heated, such as a ceramic appliance 300.
[0100] This embodiment provides a coil disk 100. In addition to the technical features of the above embodiment, this embodiment further includes the following technical features.
[0101] As Figure 5 shown, the coil 110 includes wire harnesses 112, and the wire harnesses 112 are arranged in a spiral shape; wherein, the number of wire harnesses 112 is one; and / or the number of wire harnesses 112 is multiple, and the multiple wire harnesses 112 are arranged in parallel.
[0102] In this embodiment, the coil 110 includes wire harnesses 112, and the wire harnesses 112 are arranged in a spiral shape. After the current passes through the wire harnesses 112, the wire harnesses 112 can heat themselves, thereby realizing infrared heating; the current passing through the wire harnesses 112 can also generate a magnetic field, thereby realizing electromagnetic heating of the magnetic appliance 300. The number of wire harnesses 112 is one, and one wire harness 112 is wound in a ring shape to form the coil 110.

Furthermore, the control component can flexibly control the coil 110 according to the heating requirements of the coil 110. The coil 110 can mainly use electromagnetic heating, mainly use infrared heating, or simultaneously use electromagnetic and infrared heating, improving the flexibility of controlling the coil 110 and further expanding the applicable range of the heating component.

[0122] The cross-sectional shape of the coil 110 is circular, which can effectively reduce the manufacturing cost of the coil 110, thereby reducing the overall cost of the heating component.
[0123] The cross-sectional shape of the coil 110 is pentagonal or hexagonal. While enhancing the strength of the coil 110 itself, it makes the heat generation of the coil 110 more uniform.

[0126] In this embodiment, the resistivity of the coil 110 is less than or equal to 10 -6 ohm·m, so that the coil 110 can change its heating state by adjusting the current frequency, enabling the coil 110 to achieve self-heating, that is, heating the appliance 300 placed on the heating component by infrared heating, and also heating the appliance 300 placed on the heating component by electromagnetic heating, further expanding the application range of the heating component.

And by adjusting the frequency of the current of the coil, the self-heating power and / or electromagnetic heating power of the coil are adjusted, so that the coil no longer requires a composite resistance wire, thereby simplifying the manufacturing process of the coil, reducing the manufacturing difficulty of the coil, and further reducing the manufacturing cost of the coil.
[0135] By adjusting the frequency of the current of the coil, the self-heating power and / or electromagnetic heating power of the coil are adjusted, so that the part for realizing the electromagnetic heating of the coil and the part for realizing the self-heating of the coil are the same area of the coil, thereby improving the heating uniformity.

[0139] In this embodiment, the frequency of the current passing through the coil is adjusted to a larger first frequency, so that the resistance of the coil increases, and more electrical energy of the current flowing through the coil is converted into heat energy. Furthermore, the self-heating power of the coil is greater than the electromagnetic heating power of the coil, realizing the heating of weakly magnetic appliances or non-magnetic conductive appliances by infrared heating. The frequency of the current passing through the coil is adjusted to a lower second frequency, so that the resistance of the coil decreases, and more electromagnetic energy is generated by the current flowing through the coil.

[0145] When infrared heating is required, using the skin effect, the frequency of the current passing through the coil is increased, that is, the frequency of the current passing through the coil is adjusted to a larger third frequency, so that the current is more concentrated in the second conductive part with a larger resistivity, and the self-heating power of the coil is greater than the electromagnetic heating power of the coil. Furthermore, the infrared heating of the appliance is realized through the self-heating of the second conductive part.
[0146] When electromagnetic heating is required, reduce the frequency of the current passing through the coil, that is, adjust the frequency of the current passing through the coil to a smaller fourth frequency, so that the current density passing through the first conductive part with a smaller resistivity increases, and make the self-heating power of the coil less than the electromagnetic heating power of the coil. Use the current with a relatively low frequency to pass through the first conductive part to achieve electromagnetic heating of the appliance.
