Description

Technical Field

[0001] The present invention relates to the technical field of heating components, and particularly to a coil disk, a control method for the coil disk, a control device for the coil disk, a readable storage medium, and a heating component. Background Art

[0002] Currently, electromagnetic heating components such as induction cookers are provided with electromagnetic coils, which can heat utensils placed on the induction cooker. However, to heat utensils through the electromagnetic coils, the utensils need to be ferromagnetic utensils, and electromagnetic heating cannot be achieved for non-ferromagnetic utensils.

[0003] In the related art, to enable an induction cooker to heat non-ferromagnetic utensils, the electromagnetic coil is usually combined with a resistance wire. For example, a layer of electromagnetic wire is coated outside the resistance wire, or a layer of resistance wire is coated outside the electromagnetic wire. Then, the non-ferromagnetic utensils can be heated through the resistance wire, and the ferromagnetic utensils can be heated through the electromagnetic coil. However, this kind of coil needs to compound and manufacture the electromagnetic coil and the resistance wire, making the manufacturing process of the coil relatively complex and the cost of the coil relatively high. 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 technologies.

[0005] For this reason, a first aspect of the present invention provides a coil disk.

[0006] A second aspect of the present invention provides a control method for the coil disk.

[0007] A third aspect of the present invention provides a control device for the coil disk.

[0008] A fourth aspect of the present invention provides another control device for the 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 for a heating component, the heating component being capable of generating heat or heating a load. The coil disk includes a coil and a control module, the control module is electrically connected to the coil, the control module can obtain the impedance of the load, obtain the resonance parameters for driving the coil according to the impedance of the load, and drive the coil to work according to the resonance parameters so that the coil generates heat and / or the load generates heat.

[0012] The present application provides a coil disk, which is used for a heating component that can heat a load. The coil disk includes a coil and a control module. The control module is electrically connected to the coil. The control module can obtain the impedance of the load, obtain the resonance parameters for driving the coil according to the impedance of the load, and drive the coil to operate according to the resonance parameters, so that the coil generates heat and / or the load generates heat. By detecting the impedance of the load by the control module and setting the resonance parameters for driving the coil according to the impedance of the load, the coil disk can control the driving coil to generate heat according to the impedance of the load and then heat the load, or control the coil to perform electromagnetic heating on the load, so that the load generates heat by itself. It can also control the driving coil to generate heat by itself and heat the load, and control the coil to perform electromagnetic heating on the load at the same time. The coil can be used to heat loads with different impedances, so that the coil no longer needs a composite resistance wire, reducing the requirements for the coil material and structure, thereby simplifying the manufacturing process of the coil, reducing the manufacturing difficulty of the coil, and saving costs.

[0013] Specifically, based on the principle of electromagnetic induction, since the control module is electrically connected to the coil, the control module can input an alternating current to the coil. After the current passes through the coil, a magnetic field will be generated around the coil. When the load is arranged around the coil, heat will be generated under the action of the magnetic field, thereby realizing self-heating of the load.

[0014] Specifically, when a current with a certain frequency passes through the coil, the coil generates ohmic heat due to its own internal resistance, thereby realizing heating of the coil and heating the surrounding load.

[0015] Furthermore, the control module can detect whether the load is a ferromagnetic load or a non-ferromagnetic load according to the magnitude of the impedance of the load obtained, and then the control module adjusts the resonance parameters required for driving the coil according to the magnetic conductivity of the load, so as to realize the heating treatment of ferromagnetic loads and non-ferromagnetic loads.

[0016] Specifically, when the load is a ferromagnetic load, the control module applies an alternating current with a certain frequency to the coil through the electrical connection with the coil, so that a magnetic field is generated around the coil. Based on electromagnetic induction, eddy currents are generated in the ferromagnetic load under the action of the magnetic field, and then Joule heat is generated to realize self-heating. When the load is a non-ferromagnetic load, the control module applies a current to the coil through the electrical connection with the coil, and the load around the coil is heated by the coil generating heat after being energized.

[0017] In addition, the coil disk in the above technical solution provided by the present invention may further have the following additional technical features:

[0018] In some technical solutions of the present invention, optionally, the coil disk further includes a bracket, a magnetic enhancement layer, and a heat insulation layer. The magnetic enhancement layer is arranged on the bracket and is opposite to the coil; the heat insulation layer is arranged on the magnetic enhancement layer; the coil is arranged on the side of the heat insulation layer away from the magnetic enhancement layer.

[0019] In this technical solution, the coil disk further includes a bracket, a magnetic enhancement layer, and a heat insulation layer. The magnetic enhancement layer is disposed on the bracket, and the bracket can fix the magnetic enhancement layer. The magnetic enhancement layer faces the coil. The heat insulation layer is disposed on the magnetic enhancement layer. The coil is disposed on the side of the heat insulation layer away from the magnetic enhancement layer. By providing a magnetic enhancement layer opposite to the coil, the magnetic enhancement layer can isolate the magnetic field through its own magnetism, thereby avoiding damage to the cooking appliance. At the same time, it confines the magnetic field to gather on the side of the coil disk close to the load, increasing the efficiency of electromagnetic heating.

[0020] The heat insulation layer can block the heat generated by the coil and the load. By disposing the coil on the side of the heat insulation layer away from the magnetic enhancement layer, the heat can be blocked on the side of the heat insulation layer away from the magnetic enhancement layer, reducing the influence of the heat generated by the coil and the load on the magnetic enhancement layer, preventing the magnetic enhancement layer from being affected by high temperature and reducing its function, and also avoiding damage to the magnetic enhancement layer caused by high temperature. At the same time, the heat insulation layer can also reduce the heat loss generated by the coil and the load.

[0021] Specifically, the magnetic enhancement layer has its own magnetic field, which can isolate the magnetic field generated by the coil, enabling the magnetic field generated by the coil to gather on the side where the load is located, increasing the electromagnetic heating efficiency of the coil on the load.

[0022] In some technical solutions of the present invention, optionally, the coil disk further includes an inverter module and a drive module. The inverter module is electrically connected to the coil. The drive module is electrically connected to the inverter module and also electrically connected to the control module. The control module can drive the coil to work through the drive module and the inverter module.

[0023] In this technical solution, the coil disk further includes an inverter module and a drive module. The inverter module is electrically connected to the coil. The drive module is electrically connected to the inverter module and also electrically connected to the control module. The control module can drive the coil to work through the drive module and the inverter module, realizing the control of the working state of the coil by the control module. It can control the drive coil to generate heat and then heat the load, or control the coil to perform electromagnetic heating on the load, causing the load to generate heat by itself. It can also control the drive coil to generate heat by itself and heat the load, and control the coil to perform electromagnetic heating on the load simultaneously. The resonance parameters of the coil can be changed through the control module, thereby controlling the coil to heat loads with different impedances, so that the coil no longer requires a composite resistance wire, reducing the requirements for the coil material and structure.

[0024] Specifically, the drive module is used to convert the control signal of the control module into a drive current. Since the inverter module is electrically connected to the drive module and the inverter module is electrically connected to the coil, the inverter module can convert the drive current transmitted by the drive module to the coil into an alternating current with a certain frequency.

[0025] In some technical solutions of the present invention, optionally, the coil disk further includes an impedance detection module, which is electrically connected to the coil and also electrically connected to the control module, so that the control module can control the impedance detection module to detect the overall impedance of the coil and the load.

[0026] In this technical solution, the coil disk further includes an impedance detection module, which is electrically connected to the coil and also electrically connected to the control module, so that the control module can control the impedance detection module to detect the impedance of the load, enabling the control module to detect the impedance of the load. Then, based on the impedance of the load, the control module can control the driving coil to generate heat to heat the load, or control the coil to perform electromagnetic heating on the load so that the load generates heat by itself. It can also control the driving coil to generate heat by itself and perform heating on the load, and control the coil to perform electromagnetic heating on the load simultaneously. Different impedance loads can be heated through the coil, eliminating the need for a composite resistance wire in the coil, reducing the requirements for the coil material and structure, thereby simplifying the manufacturing process of the coil, reducing the difficulty of the coil manufacturing process, and reducing the number of control circuits required for heating, saving costs.

[0027] In some technical solutions of the present invention, optionally, when the control module drives the coil to operate, the equivalent internal resistance of the coil is greater than or equal to 0.5 ohms.

[0028] In this technical solution, when the control module drives the coil to operate, the equivalent internal resistance of the coil is greater than or equal to 0.5 ohms. The value of the equivalent internal resistance affects the amount of heat generated by the coil itself after the control module energizes the coil. By setting the equivalent internal resistance of the coil to be greater than or equal to 0.5 ohms, a heating method mainly based on the coil generating heat can be achieved when the load is a non-ferromagnetic material.

[0029] Specifically, a threshold can be set to determine the equivalent internal resistance of the detected load. When the equivalent internal resistance of the coil and load system is less than the threshold, it indicates that the load is a non-ferromagnetic load, and the control module drives the coil to generate heat by itself. When the equivalent internal resistance of the coil and load system is greater than the threshold, it indicates that the load is a ferromagnetic load, and the control module drives the coil to perform electromagnetic heating on the load, and the load generates heat by itself.

[0030] Specifically, coils with different equivalent resistance values of materials can be used according to the actual parameters and usage scenarios of the heating component.

[0031] In some technical solutions of the present invention, optionally, the coil includes wire harnesses, and the number of wire harnesses is one or more. One or more wire harnesses are arranged in a spiral shape, and / or the wire harnesses are ribbon-shaped wire harnesses.

[0032] In this technical solution, the coil includes a wire harness. The number of wire harnesses is one or more. One or more strip-shaped wire harnesses are arranged in a spiral shape. The control module energizes the coil through the drive module and the inverter module. The energized wire harness generates heat by itself according to the resonance parameters and heats the load, or performs electromagnetic heating on the load, or can generate heat by itself and perform electromagnetic heating on the load at the same time. At the same time, a single wire harness can simplify the coil structure, reduce the difficulty of the coil manufacturing process, save the processing production cost of the coil, or multiple wire harnesses can be used to wind the coil by the process of uniform winding to improve the heating uniformity when the coil generates heat.

[0033] Specifically, the wire harness can be a single or multi-strand conductor wire or a conductor strip.

[0034] The second aspect of the present invention provides a control method for a coil disk, including obtaining the impedance of the load; obtaining the resonance parameters for driving the coil according to the impedance of the load; driving the coil to work according to the resonance parameters so that the coil generates heat and / or the load generates heat.

[0035] This application provides a control method for a coil disk, including obtaining the impedance of the load; obtaining the resonance parameters for driving the coil according to the impedance of the load; driving the coil to work according to the resonance parameters so that the coil generates heat and / or the load generates heat, so as to adjust the relative resonance parameters according to the obtained impedance of the load, and then change the heating mode of the coil. It can drive the coil to generate heat by itself and heat the load, or can separately control the coil to perform electromagnetic heating on the load so that the load generates heat by itself. It can also drive the coil to generate heat by itself and perform electromagnetic heating on the load at the same time. It can heat loads with different impedances through the coil, so that the coil no longer needs a composite resistance wire, reduces the requirements for the coil material and structure, simplifies the coil manufacturing process, reduces the manufacturing difficulty of the coil, and saves costs.

[0036] In some technical solutions of the present invention, optionally, obtaining the resonance parameters for driving the coil according to the impedance of the load includes adjusting the resonance parameters to the first parameter based on the impedance of the load being greater than the first threshold; adjusting the resonance parameters to the second parameter based on the impedance of the load being less than or equal to the first threshold; where, when driving the coil to work according to the first parameter, the change frequency of the magnetic field generated by the coil is the first frequency, and the current value passing through the coil is the first current value; when driving the coil to work according to the second parameter, the change frequency of the magnetic field generated by the coil is the second frequency, and the current value passing through the coil is the second current value; the first frequency is less than the second frequency, and the first current value is less than the second current value.

[0037] In this technical solution, obtaining the resonance parameters of the driving coil according to the impedance of the load includes adjusting the resonance parameters to the first parameter based on the impedance of the load being greater than the first threshold; adjusting the resonance parameters to the second parameter based on the impedance of the load being less than or equal to the first threshold; wherein, when the driving coil operates according to the first parameter, the change frequency of the magnetic field generated by the coil is the first frequency, and the current value passing through the coil is the first current value; when the driving coil operates according to the second parameter, the change frequency of the magnetic field generated by the coil is the second frequency, and the current value passing through the coil is the second current value; the first frequency is less than the second frequency, and the first current value is less than the second current value. Since the smaller the magnetic field change frequency, the greater the heat generated by the load under the electromagnetic heating of the magnetic field, when the impedance of the load is greater than the first threshold, the change frequency of the magnetic field generated by the coil becomes smaller, and the heat generated by the load under the action of the magnetic field becomes larger. Furthermore, the electromagnetic heating of the load by the coil is used as the main heating method, and the load self-heats. When the load impedance is less than the first threshold, the current value flowing through the coil becomes larger, and thus the heat generated by the coil itself increases, realizing the main heating method of heating the load by the self-heating of the coil.

[0038] By setting the first threshold, it is convenient to distinguish the impedance situation of the load, and then different heating modes of the driving coil can be controlled according to different load impedances.

[0039] Specifically, when the impedance of the load is greater than the first threshold, the load can be regarded as a ferromagnetic load, and when the impedance of the load is less than or equal to the first threshold, the load can be regarded as a non-ferromagnetic load.

[0040] In some technical solutions of the present invention, optionally, when the driving coil operates according to the first parameter, the heating power of the load is greater than the heating power of the coil; when the driving coil operates according to the second parameter, the heating power of the load is less than the heating power of the coil.

[0041] In this technical solution, when the driving coil operates according to the first parameter, the heating power of the load is greater than the heating power of the coil; when the driving coil operates according to the second parameter, the heating power of the load is less than the heating power of the coil. When the impedance of the load is greater than the first threshold, since the heating power of the load is greater than the heating power of the coil, the electromagnetic heating of the load by the magnetic field generated by the energized coil is mainly used. When the impedance of the load is less than or equal to the first threshold, since the heating power of the load is less than the heating power of the coil, the self-heating of the coil is mainly used to heat the load.

[0042] A control device for a coil disk according to a third aspect of the present invention includes a first acquisition unit, a second acquisition unit, and a control unit. The first acquisition unit is configured to acquire the impedance of a load; the second acquisition unit is configured to acquire resonance parameters for driving the coil according to the impedance of the load; and the control unit is configured to drive the coil to operate according to the resonance parameters so that the coil generates heat and / or the load generates heat.

[0043] The present application provides a control device for a coil disk, including a first acquisition unit, a second acquisition unit, and a control unit. The first acquisition unit is configured to acquire the impedance of a load; the second acquisition unit is configured to acquire resonance parameters for driving the coil according to the impedance of the load; and the control unit is configured to drive the coil to operate according to the resonance parameters so that the coil generates heat and / or the load generates heat. By acquiring the impedance of the load through the first acquisition unit, analyzing the load impedance through the second acquisition unit to obtain the resonance parameters for driving the coil, and finally controlling the working mode of the coil by the control unit based on the resonance parameters, the coil can be driven to generate heat by itself and the load can be heated, or the coil can be controlled alone to perform electromagnetic heating on the load to make the load generate heat by itself, or the coil can generate heat by itself while performing electromagnetic heating on the load. It is possible to heat loads with different impedances through the coil, so that the coil no longer requires a composite resistance wire, reducing the requirements for the coil material and structure, thereby simplifying the manufacturing process of the coil, reducing the manufacturing difficulty of the coil, and saving costs.

[0067] In order to more clearly understand the above - mentioned 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 can be combined with each other.

[0068] 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.

[0069] The following refers to Figures 1 to 11Describe 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 assembly according to some embodiments of the present invention.

[0070] A first aspect of the present invention provides a coil disk 100, as Figure 1 and Figure 2 shown. The coil disk 100 is for a heating assembly, and the heating assembly is capable of heating a load. 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 obtain the impedance of the load, obtain the resonance parameters for driving the coil 110 according to the impedance of the load, and drive the coil 110 to operate according to the resonance parameters, so that the coil 110 generates heat and / or the load generates heat.

[0071] This application provides a coil disk 100. The coil disk 100 is for a heating assembly, and the heating assembly is capable of heating a load. 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 obtain the impedance of the load, obtain the resonance parameters for driving the coil 110 according to the impedance of the load, and drive the coil 110 to operate according to the resonance parameters, so that the coil 110 generates heat and / or the load generates heat. By detecting the impedance of the load by the control module 120 and setting the resonance parameters for driving the coil 110 according to the impedance of the load, it is realized that the coil disk 100 controls the driving coil 110 to generate heat according to the impedance of the load and then heats the load, or controls the coil 110 to perform electromagnetic heating on the load, so that the load generates heat by itself. It can also control the driving coil 110 to generate heat by itself and heat the load, and control the coil 110 to perform electromagnetic heating on the load at the same time. The coil 110 can be used to heat loads with different impedances, so that the coil 110 no longer needs a composite resistance wire, reduces the requirements for the material and structure of the coil 110, thereby simplifies the manufacturing process of the coil 110, reduces the manufacturing difficulty of the coil 110, and saves costs.

[0072] Specifically, based on the principle of electromagnetic induction, since the control module 120 is electrically connected to the coil 110, the control module 120 can input an alternating current to the coil 110. After the current passes through the coil 110, a magnetic field will be generated around the coil 110. When the load is arranged around the coil 110, Joule heat will be generated under the action of the magnetic field, thereby realizing the self-heating of the load.

[0073] Specifically, when the current passes through the coil 110, due to the internal resistance of the coil 110 itself, the coil 110 generates ohmic heat under the action of the current. Therefore, the coil 110 generates heat, thereby realizing the self-heating of the coil 110 and heating the surrounding load.

[0074] Further, the control module 120 can detect whether the load is a magnetic load or a non-magnetic load according to the impedance magnitude of the obtained load, and then, according to the magnetic property of the load, the control module 120 adjusts the resonance parameters required by the drive coil 110 to achieve the heating treatment of the magnetic load and the non-magnetic load.

[0075] Specifically, when the load is a magnetic load, the control module 120 applies an alternating current with a certain frequency to the coil 110 through the electrical connection with the coil 110, so that a magnetic field is generated around the coil 110. Based on electromagnetic induction, eddy currents are generated in the ferromagnetic load under the action of the magnetic field, and then Joule heat is generated to achieve self-heating. When the load is a non-ferromagnetic load, the control template applies a current to the coil 110 through the electrical connection with the coil 110, and the load around the coil 110 is heated by the self-heating of the coil 110 after the coil 110 is energized.

[0076] Specifically, when the load is made of ferromagnetic material, the control module 120 can perform electromagnetic heating on the load by controlling the coil 110 to generate a magnetic field. When the load is made of ceramic material, the control module 120 can control the coil 110 to self-heat to heat the load.

[0077] This embodiment provides a coil disk 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0078] As Figure 2 shown, the coil disk 100 further includes a bracket 130, a magnetic enhancement layer 140, and a heat insulation layer 150. The magnetic enhancement layer 140 is disposed on the bracket 130 and is opposite to the coil 110; the heat insulation layer 150 is disposed on the magnetic enhancement layer 140; the coil 110 is disposed on the side of the heat insulation layer 150 away from the magnetic enhancement layer 140.

[0079] In this embodiment, the coil disk 100 further includes a bracket 130, a magnetic enhancement layer 140, and a heat insulation layer 150. The magnetic enhancement layer 140 is disposed on the bracket 130, and the bracket 130 can fix the magnetic enhancement layer 140. The magnetic enhancement layer 140 is opposite to the coil 110; the heat insulation layer 150 is disposed on the magnetic enhancement layer 140; the coil 110 is disposed on the side of the heat insulation layer 150 away from the magnetic enhancement layer 140. The magnetic enhancement layer 140 disposed opposite to the coil 110 can increase the magnetic field intensity generated by the energized coil 110 and improve the electromagnetic heating effect of the coil 110 on the load after energization.

[0080] The heat insulation layer 150 can block the heat generated by the coil 110 and the load. The coil 110 is arranged on the side of the heat insulation layer 150 away from the magnetic enhancement layer 140. The heat can be blocked on the side of the heat insulation layer 150 away from the magnetic enhancement layer 140 through the heat insulation layer 150, which can reduce the influence of the heat generated by the coil 110 and the load on the magnetic enhancement layer 140, avoid the high temperature from affecting the magnetic field blocking of the magnetic enhancement layer and the effect of confining the magnetic field to gather on the side of the coil disk close to the load. At the same time, the heat insulation layer 150 can also reduce the heat loss generated by the coil 110 and the load.

[0081] Specifically, the magnetic enhancement layer 140 can isolate the magnetic field through its own magnetism, thereby avoiding damage to the cooking appliance, and at the same time confining the magnetic field to gather on the side of the coil disk 100 close to the load, increasing the efficiency of electromagnetic heating.

[0082] This embodiment provides a coil disk 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0083] The coil disk 100 further includes an inverter module 160 and a drive module 170. The inverter module 160 is electrically connected to the coil 110; the drive module 170 is electrically connected to the inverter module 160 and is also electrically connected to the control module 120. The control module 120 can drive the coil 110 to work through the drive module 170 and the inverter module 160.

[0084] In this embodiment, the coil disk 100 further includes an inverter module 160 and a drive module 170. The inverter module 160 is electrically connected to the coil 110; the drive module 170 is electrically connected to the inverter module 160 and is also electrically connected to the control module 120. The control module 120 can drive the coil 110 to work through the drive module 170 and the inverter module 160, realizing the control of the working state of the coil 110 by the control module 120. It can control the drive coil 110 to generate heat and then heat the load, or control the coil 110 to perform electromagnetic heating on the load, so that the load generates heat by itself. It can also control the drive coil 110 to generate heat by itself and heat the load, and control the coil 110 to perform electromagnetic heating on the load at the same time. The resonance parameters of the coil 110 can be changed through the control module 120, and then the coil 110 can be controlled to heat loads with different impedances, so that the coil 110 no longer needs a composite resistance wire, reducing the requirements for the material and structure of the coil 110.

[0085] Specifically, the drive module 170 is used to convert the control signal of the control module 120 into a drive current. Since the inverter module 160 is electrically connected to the drive module 170 and the inverter module 160 is electrically connected to the coil 110, the inverter module 160 can convert the drive current transmitted by the drive module 170 to the coil 110 into an alternating current with a certain frequency.

[0086] Specifically, the circuit selection of the inverter module 160 can adopt a variety of topological circuits.

[0087] Specifically, a single-tube circuit, a half-bridge circuit, and a full-bridge circuit in the topological circuit can be adopted.

[0088] Specifically, as Figure 3 shown, other sensors 126 can be set to detect the parameters of the coil 110. The power supply 122 applies current to the rectification module 124. The rectification module 124 inputs the current to the inverter module 160. The inverter module 160 converts direct current into alternating current and inputs it to the coil 110 to drive the coil 110 to work. The impedance detection module 180 and other sensors 126 detect the coil 110 and feed back the detection results to the control module 120. The control module 120 controls the drive module 170 to output drive current according to the feedback signals of the impedance detection module 180 and other sensors 126, and then converts direct current into alternating current through the inverter module 160 and transmits it to the coil 110.

[0089] Specifically, other sensors 126 can be temperature sensors to detect the temperature of the coil 110.

[0090] This embodiment provides a coil disk 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0091] The coil disk 100 further includes an impedance detection module 180. The impedance detection module 180 is electrically connected to the coil 110 and also electrically connected to the control module 120, so that the control module 120 can control the impedance detection module 180 to detect the impedance of the load.

[0092] In this embodiment, the coil disk 100 further includes an impedance detection module 180. The impedance detection module 180 is electrically connected to the coil 110 and also electrically connected to the control module 120, so that the control module 120 can control the impedance detection module 180 to detect the impedance of the load, realize the control module 120 to detect the impedance of the load, and then control the driving coil 110 to generate heat to heat the load according to the impedance of the load, or control the coil 110 to perform electromagnetic heating on the load to make the load generate heat by itself. It can also control the driving coil 110 to generate heat by itself and heat the load, and control the coil 110 to perform electromagnetic heating on the load at the same time. Different impedance loads can be heated through the coil 110, so that the coil 110 no longer needs a composite resistance wire, reducing the requirements for the material and structure of the coil 110, thereby simplifying the manufacturing process of the coil 110, reducing the manufacturing difficulty of the coil 110, and saving costs.

[0093] This embodiment provides a coil disk 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0094] When the control module 120 drives the coil 110 to work, the equivalent internal resistance of the coil 110 is greater than or equal to 0.5 ohms.

[0095] In this embodiment, when the control module 120 drives the coil 110 to work, the equivalent internal resistance of the coil 110 is greater than or equal to 0.5 ohms. The value of the equivalent internal resistance will affect the amount of heat generated by the coil 110 itself after the control module 120 energizes the coil 110. That is, when the equivalent resistance is less than 0.5 ohms, it is convenient for the coil 110 to perform electromagnetic heating on the load, but the heat generated by itself is relatively small. Since the coil 110 needs to switch between the electromagnetic heating mode and the self-heating mode, the coil 110 needs a relatively large resistance for self-heating. Therefore, the coil 110 needs to have an equivalent resistance value greater than that of the conventional coil disk 100. Therefore, using a coil 110 with an equivalent resistance greater than or equal to 0.5 ohms can improve the self-heating effect of the coil 110.

[0096] Specifically, according to the heating situation of the load, a material with a reasonable conductivity can be selected to wind the coil 110, and the hybrid coil 110 can be obtained by winding a wire harness 112 composed of a single or multiple conductor wires, or the hybrid coil 110 can also be obtained by winding a wire harness 112 of a strip material, as Figure 4 shown, the equivalent resistance of the hybrid coil 110 is much greater than that of the conventional electromagnetic coil 110. After adding a load, the equivalent resistance of the hybrid coil 110 and the load is much greater than that of the conventional electromagnetic coil 110 and the load.

[0097] Specifically, the value of the equivalent internal resistance of the coil 110 is set to be greater than or equal to 0.5 ohms. Since the value of the equivalent internal resistance will affect the amount of heat generated by the coil 110 itself after the control module 120 energizes the coil 110, when the value of the equivalent internal resistance of the coil 110 is greater than or equal to 0.5 ohms, the Joule heat generated by the coil 110 after energization can be increased. Furthermore, when the equivalent internal resistance of the load is less than the equivalent internal resistance of the coil, the coil disk 100 mainly generates heat with the coil 110.

[0098] Specifically, according to the actual parameters and usage scenarios of the heating component, coils 110 with different equivalent resistance values of materials can be used.

[0099] This embodiment provides a coil disk 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0100] The coil 110 includes a wire harness 112. The number of the wire harnesses 112 is one or more, and the one or more wire harnesses 112 are arranged in a spiral shape.

[0101] In this embodiment, the coil 110 includes a wire harness 112. The number of wire harnesses 112 is one or more. One or more wire harnesses 112 are arranged in a spiral shape. The control module 120 energizes the coil 110 through the drive module 170 and the inverter module 160. The energized wire harness 112 generates heat by itself according to the resonance parameters and heats the load, or performs electromagnetic heating on the load, or can generate heat by itself and perform electromagnetic heating on the load at the same time. The spiral arrangement of multiple wire harnesses 112 can improve the heating uniformity when the wire harnesses 112 generate heat, and the uniformity of the magnetic field generated by the energized wire harness 112 can also be improved by adjusting the combination mode of multiple wire harnesses. At the same time, using a single wire harness 112 can simplify the structure of the coil 110, reduce the difficulty of the manufacturing process of the coil 110, and save the processing and production cost of the coil 110.

[0102] As Figure 5 shown, the second aspect of the present invention provides a control method for a coil disk, and the steps include:

[0103] Step 201, obtain the impedance of the load;

[0104] Step 202, obtain the resonance parameters of the drive coil according to the impedance of the load;

[0105] Step 203, drive the coil to work according to the resonance parameters so that the coil generates heat and / or the load generates heat.

[0106] The present application provides a control method for a coil disk, including obtaining the impedance of the load; obtaining the resonance parameters of the drive coil according to the impedance of the load; driving the coil to work according to the resonance parameters so that the coil generates heat and / or the load generates heat, so as to adjust the relative resonance parameters according to the obtained impedance of the load, and then change the heating mode of the coil. The coil can be driven to generate heat by itself and heat the load, or the coil can be controlled to perform electromagnetic heating on the load so that the load generates heat by itself. It can also drive the coil to generate heat and perform electromagnetic heating on the load at the same time. Different impedance loads can be heated through the coil, so that the coil no longer needs a composite resistance wire, reducing the requirements for the coil material and structure, thereby simplifying the manufacturing process of the coil, reducing the manufacturing difficulty of the coil, and saving costs.

[0107] This embodiment provides a control method for a coil disk. In addition to the technical features of the above embodiment, this embodiment further includes the following technical features.

[0108] Obtaining the resonance parameters of the drive coil according to the impedance of the load includes adjusting the resonance parameters to a first parameter based on the impedance of the load being greater than a first threshold; and adjusting the resonance parameters to a second parameter based on the impedance of the load being less than or equal to the first threshold. Wherein, when the drive coil operates according to the first parameter, the change frequency of the magnetic field generated by the coil is a first frequency, and the current value passing through the coil is a first current value; when the drive coil operates according to the second parameter, the change frequency of the magnetic field generated by the coil is a second frequency, and the current value passing through the coil is a second current value; the first frequency is less than the second frequency, and the first current value is less than the second current value.

[0109] In this embodiment, obtaining the resonance parameters of the drive coil according to the impedance of the load includes adjusting the resonance parameters to a first parameter based on the impedance of the load being greater than a first threshold; and adjusting the resonance parameters to a second parameter based on the impedance of the load being less than or equal to the first threshold. Wherein, when the drive coil operates according to the first parameter, the change frequency of the magnetic field generated by the coil is a first frequency, and the current value passing through the coil is a first current value; when the drive coil operates according to the second parameter, the change frequency of the magnetic field generated by the coil is a second frequency, and the current value passing through the coil is a second current value; the first frequency is less than the second frequency, and the first current value is less than the second current value. When the impedance of the load is greater than the first threshold, the impedance of the load is greater than the impedance of the coil. At this time, the change frequency of the magnetic field generated by the coil is less than the change frequency when the impedance is less than the first threshold. Therefore, the main method is to drive the load to generate electromagnetic heat through the coil. When the impedance of the load is less than the first threshold, the impedance of the load is less than the impedance of the coil. At this time, the first current value passing through the coil is greater than the second current value, and the coil disk forms ohmic heat through its own internal resistance. Therefore, at this time, the self-heating of the coil is the main method.

[0110] By setting the first threshold, it is convenient to distinguish the impedance situation of the load, and then realize different control of the heating mode of the drive coil according to different load impedances.

[0111] Specifically, when the impedance of the load is greater than the first threshold, the load can be regarded as a magnetic conductive load; when the impedance of the load is less than or equal to the first threshold, the load can be regarded as a non-magnetic conductive load.

[0112] Specifically, the magnetic conductive load can be metal and ferromagnetic load. On the contrary, the non-magnetic conductive load can be non-metal and non-ferromagnetic load.

[0113] Specifically, a material with appropriate resistivity and resistance to thermal corrosion can be selected to make the coil. Alternatively, a single conductor wire can be used to wind the coil, and a heat insulation layer can be added between the coil, the magnetic enhancement layer, and other structures. By modifying the winding method of the coil and the structure of the coil disk, the equivalent internal resistance of the coil disk increases significantly when there is no load, so that when there is no metal material load or a non-ferromagnetic load is set, after an alternating current passes through the coil, the coil can still generate a large amount of heat, and at this time the coil replaces the load as the main heating component. At the same time, the control circuit can control the magnitude of the power output, and use infrared thermal radiation or heat conduction to heat the non-metallic material load or the non-ferromagnetic load. On the contrary, when the load is a metal load and a ferromagnetic load, the equivalent internal resistance of the entire system will increase. At this time, due to the electromagnetic effect, the magnetic field generated by the eddy current on the load will limit the current in the coil, resulting in more heat being generated on the load, and the load is the main heating component.

[0114] Specifically, the impedance of the load can be detected by the control circuit, and the resonance parameters of the driving coil can be modified according to the detected load impedance, so as to realize that one coil can heat the magnetic load and the non-magnetic load respectively. At the same time, the control system can be set to intelligently distribute power according to the load conditions detected by the control circuit, and use the self-heating and electromagnetic heating of the coil to realize the function of hybrid power heating of the coil disk.

[0115] Specifically, according to the modified resonance parameters of the driving coil, when the load is a non-metallic load or a non-ferromagnetic load, the current flowing through the coil can be increased to make the coil heat more easily. When the load is a metal load or a ferromagnetic load, the change of the magnetic field in the system can be increased to make the load generate heat more easily. Furthermore, by using the same coil and intelligently distributing the power required for work by the system, the eddy current heating of the load and the self-heating of the coil are comprehensively utilized to realize the function of hybrid power heating of the coil disk.

[0116] This embodiment provides a control method for a coil disk. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0117] When the coil is driven to work according to the first parameter, the heating power of the load is greater than the heating power of the coil; when the coil is driven to work according to the second parameter, the heating power of the load is less than the heating power of the coil.

[0118] In this embodiment, when the coil is driven according to the first parameter, the heating power of the load is greater than that of the coil; when the coil is driven according to the second parameter, the heating power of the load is less than that of the coil. When the impedance of the load is greater than the first threshold, since the heating power of the load is greater than that of the coil, electromagnetic heating of the load is mainly performed by the magnetic field generated by energizing the coil. When the impedance of the load is less than or equal to the first threshold, since the heating power of the load is less than that of the coil, heating of the load is mainly performed by the self-heating of the coil.

[0119] Specifically, as Figure 6 shown, the steps of the control method of the coil disk further include the following steps:

[0120] Step 211, obtaining the impedance of the load;

[0121] Step 212, determining whether the impedance of the load is greater than the first threshold;

[0122] If the determination result of step 212 is yes, execute step 213; if the determination result of step 212 is no, execute step 214;

[0123] Step 213, the control module selects the working mode of electromagnetic heating of the load through the coil;

[0124] Step 214, the control module selects the working mode of heating the load through the self-heating of the coil;

[0125] Step 215, obtaining the resonance parameters of the driving coil;

[0126] Step 216, driving the coil to generate heat and / or the load to generate heat according to the resonance parameters.

[0127] As Figure 7 shown, a third aspect of the present invention provides a control device 300 for a coil disk, including a first acquisition unit 310, a second acquisition unit 320, and a control unit 330. The first acquisition unit 310 is used to acquire the impedance of the load; the second acquisition unit 320 is used to acquire the resonance parameters of the driving coil according to the impedance of the load; the control unit 330 is used to drive the coil to work according to the resonance parameters so that the coil generates heat and / or the load generates heat.

By implementing the acquisition of the load impedance by the first acquisition unit 310, analyzing the load impedance by the second acquisition unit 320 to obtain the resonance parameters of the driving coil, and finally controlling the operating mode of the coil by the control unit 330 based on the resonance parameters, the coil can be driven to generate heat by itself and heat the load, or the coil can be separately controlled to perform electromagnetic heating on the load to make the load generate heat by itself. It is also possible to perform electromagnetic heating on the load while driving the coil to generate heat by itself. Different impedance loads can be heated through the coil, eliminating the need for a composite resistance wire in the coil, reducing the requirements for the coil material and structure, thereby simplifying the manufacturing process of the coil, reducing the manufacturing difficulty of the coil, and saving costs.
