Description

Technical Field

[0001] The utility model relates to the technical field of cooking equipment, in particular to a coil plate and cooking equipment. Background Art

[0002] In the related art, on the electric ceramic stove plate, two outlets of the winding are connected to the same area, the two outlets are welded to a set of terminals through resistance welding, and then connected to the circuit board through wires.

[0003] However, this wiring method is not suitable for structures such as spiral windings that require separate wiring at the inner and outer ends, and cannot meet electrical connection requirements with a set of terminals.

[0004] Therefore, how to overcome the above-mentioned technical defects has become a technical problem that needs to be solved urgently. Utility Model Content

[0005] The utility model aims to solve at least one of the technical problems existing in the prior art.

[0006] To this end, a first aspect of the utility model provides a coil disk.

[0007] A second aspect of the present invention provides a cooking device.

[0008] In view of this, the first aspect of the utility model provides a coil disk, which includes: a thermal insulation component, including a through hole; a winding, which is wound on the first side of the thermal insulation component to form a coil, and the coil can generate thermal radiation and an electromagnetic field when energized; an electrical connection component, which is at least partially arranged on the second side of the thermal insulation component; wherein the electrical connection component is connected to the winding through the through hole, or the winding partially extends to the second side of the thermal insulation component through the through hole, and the electrical connection component is connected to the winding located on the second side of the thermal insulation component.

[0009] The present application defines a coil disk having electromagnetic heating function and thermal radiation heating function.

[0010] The coil disk includes a winding, which is spirally wound to form a spiral coil. When the spiral coil is energized, an electromagnetic field can be generated thereon. At the same time, due to the existence of a certain internal resistance of the coil, the energized coil can also generate heat radiation at the same time.

[0011] Among them, the electromagnetic field intensity and heat radiation intensity generated by the coil can be distributed by changing the frequency of the power supply current of the coil. Specifically, after a high-frequency current is passed through the coil, the coil can not only generate an electromagnetic field, but also generate heat due to its own impedance. When the coil assembly resonates with the resonant capacitor at a higher resonant frequency, the impedance value of the coil itself will increase significantly due to the skin effect of the coil. When the impedance of the coil increases, the heat generated when the current passes through the coil will also increase. Therefore, the coil itself can generate enough heat, which is transferred to the cooking utensil to heat the cooking utensil.

[0012] During operation, if a magnetic cooking utensil is placed above the coil disk, the magnetic cooking utensil will resonate in the electromagnetic field and generate eddy currents. Under the action of the eddy currents, the magnetic cooking utensil gradually heats up, so that food can be cooked by the high-temperature magnetic cooking utensil. At the same time, the heat radiation generated by the coil can also provide auxiliary heating for the magnetic cooking utensil to increase the heating power.

[0013] If a non-magnetic cooking utensil is placed on top of the coil disk, although the non-magnetic cooking utensil cannot generate eddy currents through resonance in the electromagnetic field, the heat radiation generated by the coil can directly heat the non-magnetic cooking utensil, thereby cooking food with the high-temperature non-magnetic cooking utensil. And because the coil generates a large amount of heat radiation, when the user flips the pot, the actual heating effect of the coil disk on the cooking utensil will not be affected by the migration of the cooking utensil, thereby simulating the effect of open flame cooking.

[0014] The coil disk also includes a heat insulating component, the first side of the heat insulating component faces the cooking utensil, the coil is arranged on the first side of the heat insulating component, and the second side of the heat insulating component faces away from the cooking utensil. The heat insulating component has excellent heat insulating performance, and can reduce the heat diffused from the high-temperature cooking utensil and the high-temperature coil to the second side of the heat insulating component, so as to reduce the heat loss of the coil disk during the heating process and improve the heating energy efficiency of the coil disk. At the same time, the heat insulating component can also reduce the heat transferred from the coil to the structure on the second side of the heat insulating component, for example, reduce the heat transferred from the coil to the magnetic part, so that the magnetic part can be kept in a lower temperature range during the working process, so as to reduce the possibility of high-temperature demagnetization of the magnetic part, thereby improving the reliability of the coil disk and reducing the failure rate of the coil disk.

[0015] On this basis, a through hole is provided on the thermal insulation component, which connects the first side and the second side of the thermal insulation component. The coil disk also includes an electrical connection component, which is at least partially installed on the second side of the thermal insulation component. The electrical connection component is used to connect the winding and the circuit board. The power supply circuit can supply power to the winding through the electrical connection component, thereby generating thermal radiation and an electromagnetic field through the energized coil.

[0016] In the first case, the electrical connection component extends from the through hole to the first side of the thermal insulation component, and is connected to the end of the winding on the first side of the thermal insulation component, thereby forming an energized circuit. At this time, the routing of the winding and the routing of the electrical connection component do not interfere with each other, and the electrical connection component located on the second side of the thermal insulation component can freely select the outlet direction of the inner end or the outer end of the spirally wound winding according to needs.

[0017] In the second case, the end of the winding extends to the second side of the thermal insulation component through the through hole, and the electrical connection component is connected to the winding passing through the through hole on the second side of the thermal insulation component to form an energized circuit. The heating performance of the coil is mainly affected by the winding shape on the first side of the thermal insulation component. Similarly, the routing of the winding on the first side of the thermal insulation component and the routing of the electrical connection component on the second side of the thermal insulation component do not interfere with each other. The electrical connection component located on the second side of the thermal insulation component can freely select the outlet direction of the inner end or the outlet direction of the outer end of the spirally wound winding according to needs.

[0018] It can be seen that by setting a through hole on the thermal insulation component and setting an electrical connection component on the second side of the thermal insulation component in conjunction with the through hole, the inner and outer ends of the winding can be connected separately with the help of the through hole, thereby eliminating the possibility of wiring interference between the electrical connection line and the winding, thereby solving the technical defect in the related technology that the inner and outer ends of the winding cannot be connected separately, and further achieving the technical effect of optimizing the coil disk wiring structure and reducing the difficulty of electrical connection of the coil disk.

[0019] Specifically, the raw material of the winding wound into the coil is a high-temperature resistant metal material, and the linear expansion coefficient of the high-temperature resistant metal material is low to avoid high-temperature damage or high-temperature deformation of the coil. Specifically, the coil can be prepared by copper alloy or iron alloy.

[0020] Specifically, the material of the heat insulation component can be a mixture of white carbon black and moissanite, or can be flexible vacuum silicon insulation wool.

[0021] In addition, the coil disk provided by the present invention may also have the following additional technical features:

[0022] In some technical solutions of the utility model, specifically, the coil disk also includes: a supporting component, the first side of the supporting component includes a receiving groove, and the heat insulation component and the coil are arranged in the receiving groove; wherein the supporting component includes a via hole, the via hole is opposite to the through hole, and the electrical connection component or the winding is passed through the through hole and the via hole.

[0023] In this technical solution, the coil disk also includes a support component, which is connected to the heat insulation component and can provide support and protection for the heat insulation component and the coil. After power is turned on, the heat radiation generated by the coil is blocked by the heat insulation component to reduce the working temperature of the support component and avoid high-temperature melting of the support component.

[0024] A receiving groove is formed on the first side of the supporting component, the receiving groove faces the cooking utensil, and the heat insulating component and the coil are arranged in the receiving groove.

[0025] On this basis, the electrical connection assembly is arranged on the second side of the support component away from the cooking utensil, and the support component is located between the heat insulating component and the electrical connection assembly. The support component is provided with a via hole, which is opposite to the through hole after assembly, and the via hole and the through hole are connected to the first side of the heat insulating component and the second side of the support component.

[0026] When electrically connecting the winding, the winding can extend through the through hole and the via to the second side of the supporting component, and the electrical connection component connects the end of the winding on the second side of the supporting component, or the electrical connection component extends from the through hole and the via to the first side of the thermal insulation component, and the electrical connection component connects the end of the winding on the first side of the thermal insulation component.

[0027] It can be seen that by setting the via hole, the end of the electrical connection component or the winding can cross the support component to complete the electrical connection, so that the electrical connection component can be arranged outside the support component on the basis of meeting the requirements of two-end lead-out, avoiding interference between the electrical connection component and the support component. This can optimize the coil disk structure layout, improve the compactness of the coil disk structure, and provide convenient conditions for the miniaturization design of the coil disk.

[0028] In some technical schemes of the utility model, specifically, the winding is spirally coiled on the first side of the thermal insulation component; the winding includes an inner end and an outer end, the through hole includes a first through hole and a second through hole, the electrical connection component is connected to the inner end of the winding through the first through hole, and the electrical connection component is connected to the outer end of the winding through the second through hole.

[0029] In this technical solution, the winding is spirally wound on the first side of the insulation component to form a spiral coil that can simultaneously generate thermal radiation and electromagnetic field, the inner end of the coil is located in the central area of ​​the insulation component, and the outer end of the coil is located in the edge area of ​​the insulation component.

[0030] On this basis, a first through hole and a second through hole are provided on the thermal insulation component. The first through hole is provided in the central area of ​​the thermal insulation component, and the electrical connection component is connected to the inner end of the winding through the first through hole. The second through hole is provided in the edge area of ​​the thermal insulation component, and the electrical connection component is connected to the outer end of the winding through the second through hole, thereby realizing independent output wires at the inner and outer ends of the spiral coil.

[0031] It can be seen that by respectively providing the first through hole and the second through hole for the inner and outer ends of the winding, the inner and outer ends of the winding can be wired nearby to shorten the wire distance between the end of the winding and the electrical connection component, thereby improving the structural compactness of the coil disk and providing convenient conditions for the miniaturization and lightweight design of the coil disk.

[0032] In some technical schemes of the utility model, specifically, the electrical connection component includes: a wire, which is arranged on the second side of the thermal insulation component; a first terminal, which is passed through the through hole and the via, and the first terminal connects the winding and the first end of the wire; a second terminal, which is connected to the second end of the wire, and the second terminal is used to connect the circuit board.

[0033] In this technical solution, the electrical connection assembly includes a wire, a first terminal and a second terminal.

[0034] The wire is arranged on the second side of the thermal insulation component, the first terminal is connected to the first end of the wire, the second terminal is connected to the second end of the wire, the wire is connected to the winding through the first terminal, and the wire is connected to the power supply circuit on the circuit board through the second terminal. Specifically, the first terminal can be inserted into the through hole and the via to connect the winding on the first side of the thermal insulation component, or the first terminal can be fixed on the second side of the thermal insulation component, and the through hole and the winding passing through the via are connected through the first terminal.

[0035] This structure realizes independent connection between the winding and the two sides of the circuit board by setting the first terminal and the second terminal, so that the winding assembly step and the electrical connection step can be performed independently, thereby achieving the technical effect of optimizing the electrical connection component structure, reducing the difficulty of electrical connection, and reducing the complexity of coil disk assembly.

[0036] In some technical solutions of the present utility model, specifically, the wire is at least partially attached to the second side of the supporting component, and the second terminal is located on the peripheral side of the supporting component.

[0037] In this technical solution, the wire is at least partially attached to the second side of the supporting component, and the supporting component can provide positioning and support for the wire to avoid loosening or deformation of the wire, thereby improving the electrical connection reliability of the coil disk.

[0038] In this case, the second end of the wire extends from the second side of the supporting component to the peripheral side of the supporting component, thereby realizing lateral outlet of the coil disk to avoid the wire and the second terminal occupying the space on the second side of the supporting component, thereby reducing the thickness of the coil disk and providing convenient conditions for the ultra-thin design of the coil disk and the cooking device.

[0039] In some technical solutions of the utility model, specifically, the wire includes: a first wire, the first wire is connected to the inner end of the winding; a second wire, the second wire is connected to the outer end of the winding; wherein the first wire and the second wire are arranged side by side on the second side of the thermal insulation component.

[0040] In this technical solution, the wire includes a first wire and a second wire, the first wire is connected to the inner end of the winding through the first terminal, and the first wire is connected to the power supply circuit on the circuit board through the second terminal. The second wire is connected to the outer end of the winding through the first terminal, and the second terminal is connected to the power supply circuit on the circuit board through the second terminal.

[0041] The first wire and the second wire are arranged side by side on the second side of the support component, and both the first wire and the second wire extend in the radial direction of the coil, wherein the first wire connected to the inner end of the winding has a longer lead length, and the second wire connected to the outer end of the winding has a shorter lead length.

[0042] This structure realizes independent wire output at the inner and outer ends of the winding through the first wire and the second wire, and improves the structural compactness of the electrical connection component by arranging the first wire and the second wire side by side, reduces the space occupied by the electrical connection component, and provides convenient conditions for the miniaturization and lightweight design of the coil disk.

[0043] In some technical solutions of the present utility model, specifically, the second side of the supporting component includes a limiting groove, and the wire is clamped in the limiting groove.

[0044] In this technical solution, a limiting groove is provided on the second side of the support component, and the shape and size of the limiting groove are adapted to the shape and size of the wire. Specifically, the limiting groove can be formed by integrally forming a wire clamp on the second side of the support component. During the assembly process, the wire can be pressed into the limiting groove to complete the positioning and installation of the wire on the second side of the support component, so as to reduce the possibility of the wire being misplaced or even falling off, thereby achieving the technical effect of improving the positioning accuracy and positioning reliability of the wire and improving the electrical connection reliability of the coil disk.

[0045] In some technical solutions of the present utility model, specifically, the coil disk further includes: a fixing member connected to the supporting component, and the conductive wire is clamped between the fixing member and the supporting component.

[0046] In this technical solution, the coil disk further includes a fixing member, which is arranged on the second side of the supporting member and connected to the supporting member. During the assembly process, the wire is first placed at a predetermined installation position and initially positioned through the limiting groove, and then the wire is clamped on the supporting member through the fixing member to prevent the wire from being misplaced or even falling off on the supporting member.

[0047] Specifically, a single fixing member can simultaneously fix the first conductive wire and the second conductive wire arranged side by side.

[0048] By setting the fixing parts, the positioning accuracy of the wire can be improved in cooperation with the limiting groove, and the possibility of electrical connection failure due to loosening and misalignment of the wire can be reduced, thereby reducing the electrical connection failure rate of the coil disk and improving the practicality and reliability of the coil disk.

[0049] In some technical solutions of the utility model, specifically, the winding is passed through the through hole and the via hole; the winding includes a first section and a second section, the first section is spirally coiled on the first side of the thermal insulation component, and the second section is connected to the electrical connection component on the second side of the support component.

[0050] In this technical solution, the winding is inserted into the through hole and the via hole, and the inner end and the outer end of the winding extend to the second side of the thermal insulation component through the through hole and the via hole.

[0051] On this basis, the winding includes a first section and a second section. The cross-sectional shape of the first section is rectangular, and the first section is wound into a coil on the first side of the thermal insulation component.

[0052] The second section is located on the second side of the heat insulating component and extends toward the peripheral side of the heat insulating component. The electrical connection assembly is connected to the second section on the peripheral side of the heat insulating component.

[0053] Under this structure, the second section on the winding directly serves as the wire output structure, and the electrical connection component can complete the electrical connection operation between the inner and outer ends of the winding with the second section on the second side of the thermal insulation component, eliminating the steps of inserting the first terminal into the through hole, welding the first terminal by resistance, and arranging the wire on the second side of the thermal insulation component, thereby reducing the difficulty of connecting the electrical connection component and the winding, thereby achieving the technical effect of reducing the difficulty and complexity of assembling the coil disk.

[0054] In some technical solutions of the present utility model, specifically, the electrical connection assembly also includes: a third terminal connected to the second section.

[0055] In this technical solution, the electrical connection assembly also includes a third terminal, which is connected to the second section and is located on the peripheral side of the thermal insulation component. The third terminal is used to connect to the power supply circuit on the circuit board.

[0056] It can be seen that under this structure, the assembly of the winding and the output of the winding can be completed simultaneously. Specifically, the first section and the second section can be formed on the insulation component through split casting, and finally the assembly of the coil disk can be completed by connecting the third terminal, thereby achieving the technical effect of reducing the structural complexity of the coil disk and reducing the difficulty of assembling the coil disk.

[0057] In some technical solutions of the present utility model, specifically, the second section includes a folded section, and the folded section is a multi-layer structure in the width direction of the winding.

[0058] In this technical solution, the second section includes a folded section, and the folded section is a multi-layer structure in the width direction of the winding. Specifically, the second section can be obtained by transversely folding the strip-shaped winding.

[0059] The folded sections formed by folding the winding multiple times can increase the overcurrent capacity of the second section, so that the second section can meet the power supply requirements of the first section, ensuring that the second section can replace the function of the wire, and the contact winding is used as the current conduction limit of the outgoing line structure. This achieves the technical effect of optimizing the winding structure, widening the power range of the coil disk, and enhancing the heating performance of the coil disk.

[0060] In some technical solutions of the present utility model, specifically, the diameter of the through hole is a first diameter, and the range of the first diameter is: greater than or equal to 2.5 mm and less than or equal to 12.5 mm.

[0061] In this technical solution, the diameter of the through hole on the thermal insulation component is a first diameter, and the first diameter needs to be greater than or equal to 2.5 mm and less than or equal to 12.5 mm.

[0062] By limiting the first diameter to be greater than or equal to 2.5 mm, it can be ensured that the width of the first terminal or winding in the through hole can meet the overload current requirement, ensuring that the power supply current that can be conducted matches the heating requirement.

[0063] By limiting the first diameter to be less than or equal to 12.5 mm, it is possible to reduce damage to the thermal insulation component caused by the through hole while meeting the power supply demand, ensure that the thermal insulation component has sufficient rigidity, ensure that the thermal insulation component can provide stable and effective support for the coil, and reduce the possibility of breakage of the thermal insulation component.

[0064] Specifically, when the coil disk is applied to an induction cooker, the first diameter is greater than or equal to 5 mm and less than or equal to 7 mm.

[0065] In some technical solutions of the present utility model, specifically, the diameter of the via hole is a second diameter, the second diameter is larger than the first diameter; and the difference between the second diameter and the first diameter is greater than or equal to 2 mm.

[0066] In this technical solution, the diameter of the via on the thermal insulation component is the second diameter, and the second diameter is larger than the first diameter. Considering that the winding or the first terminal in the via will generate heat, and there will be deviations in the installation of the via and the through hole on the thermal insulation component, the second diameter needs to be larger than the first diameter to achieve heat dissipation through the gap formed by the size difference and compensate for the assembly error through the size difference.

[0067] On this basis, by limiting the difference between the second diameter and the first diameter to be greater than or equal to 2 mm, the damage caused by the via to the supporting component can be reduced while meeting the heat dissipation requirements and assembly error compensation requirements, thereby improving the structural strength of the supporting component and reducing the failure rate of the supporting component.

[0068] In some technical solutions of the present utility model, specifically, the coil disk also includes: a magnetic component, which is arranged on the second side of the heat insulation component, and the magnetic component avoids the electrical connection component.

[0069] In this technical solution, the coil disk also includes a magnetic member, which is arranged opposite to the coil and located on the side of the coil away from the cooking utensil. By arranging the magnetic member, the distribution of the electromagnetic field on the side of the coil away from the cooking utensil can be changed, so that the electromagnetic field generated by the coil can be concentrated on the side where the cooking utensil is located, so as to heat the cooking utensil in a centralized manner, thereby achieving the technical effect of improving the electromagnetic heating efficiency and electromagnetic heating energy efficiency.

[0070] The heat insulating component is arranged between the coil and the magnetic component, the first side of the heat insulating component faces the cooking utensil, the coil is arranged on the first side of the heat insulating component, the second side of the heat insulating component faces away from the cooking utensil, and the magnetic component is arranged on the second side of the heat insulating component. The heat insulating component has excellent heat insulating performance, which can reduce the heat diffused from the high-temperature cooking utensil and the high-temperature coil to the magnetic component, so that the magnetic component is kept at a low temperature during operation, avoiding the magnetic component from losing its magnetism due to high temperature, and ensuring the working reliability of the coil disk.

[0071] A second aspect of the utility model provides a cooking device, which includes: a body; and a coil disk as in any of the above technical solutions, which is arranged on the body.

[0072] In this technical solution, a cooking device provided with the coil disk in any of the above technical solutions is proposed, so the cooking device has the advantages of the coil disk in any of the above technical solutions and can achieve the technical effects that can be achieved by the coil disk in any of the above technical solutions. To avoid repetition, it will not be described here.

[0073] On this basis, the cooking device also includes a body, which is the main frame structure of the cooking device. The body is used to position, support and protect other working structures on the cooking device. The coil disk can be set inside the body, and the coil disk can also be embedded on the top of the body to heat the cooking utensils placed on the cooking device through the coil disk.

DETAILED DESCRIPTION

[0090] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0091] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0092] Refer to the following Figures 1 to 12 A coil pan and a cooking device according to some embodiments of the present invention are described.

[0093] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of the utility model provides a coil disk 100, which includes: a heat insulating component 110, including a through hole 112; a winding 120, the winding 120 is coiled on the first side of the heat insulating component 110 to form a coil 1202, and the coil 1202 can generate thermal radiation and an electromagnetic field after being energized; an electrical connection component 150, at least partially arranged on the second side of the heat insulating component 110; wherein the electrical connection component 150 is connected to the winding 120 through the through hole 112, or the winding 120 partially extends to the second side of the heat insulating component 110 through the through hole 112, and the electrical connection component 150 is connected to the winding 120 located on the second side of the heat insulating component 110.

[0094] Figure 1 The middle arrow a shows the heat radiation transfer direction of the coil 1202 .

[0095] The present application defines a coil disk 100 , which has electromagnetic heating function and thermal radiation heating function.

[0096] The coil disk 100 includes a winding 120, which is spirally wound to form a spiral coil 1202. When the spiral coil 1202 is energized, an electromagnetic field can be generated thereon. At the same time, since the coil 1202 has a certain internal resistance, the energized coil 1202 can also generate heat radiation at the same time.

[0097] Among them, the electromagnetic field intensity and heat radiation intensity generated by the coil 1202 can be distributed by changing the frequency of the power supply current of the coil 1202. Specifically, after the high-frequency current is passed through the coil 1202, the coil 1202 can not only generate an electromagnetic field, but also the coil 1202 itself will generate heat due to its own impedance. When the coil 1202 component resonates with the resonant capacitor at a higher resonant frequency, due to the skin effect of the coil 1202, the impedance value of the coil 1202 itself will be significantly increased. When the impedance of the coil 1202 is increased, the heat generated when the current passes through the coil 1202 will also increase accordingly, so that the coil 1202 itself can generate enough heat, and this heat is transferred to the cooking utensil 200 to heat the cooking utensil 200.

[0098] During operation, if a magnetic cooking utensil 200 is placed above the coil disk 100, the magnetic cooking utensil 200 will resonate in the electromagnetic field and generate eddy currents. Under the action of the eddy currents, the magnetic cooking utensil 200 will gradually heat up, so that food can be cooked by the high-temperature magnetic cooking utensil 200. At the same time, the heat radiation generated by the coil 1202 can also provide auxiliary heating for the magnetic cooking utensil 200 to increase the heating power.

[0099] If a non-magnetic cooking utensil 200 is placed on the coil disk 100, although the non-magnetic cooking utensil 200 cannot generate eddy currents through resonance in the electromagnetic field, the heat radiation generated by the coil 1202 can directly heat the non-magnetic cooking utensil 200, thereby cooking food with the high-temperature non-magnetic cooking utensil 200. In addition, since the coil 1202 generates a large amount of heat radiation, when the user flips the pot, the actual heating effect of the coil disk 100 on the cooking utensil 200 will not be affected by the migration of the cooking utensil 200, thereby simulating the effect of open flame cooking.

[0100] The coil disk 100 further includes a heat insulating component 110, a first side of the heat insulating component 110 faces the cooking utensil 200, the coil 1202 is arranged on the first side of the heat insulating component 110, and a second side of the heat insulating component 110 faces away from the cooking utensil 200. The heat insulating component 110 has excellent heat insulating properties, and can reduce the heat diffused from the high-temperature cooking utensil 200 and the high-temperature coil 1202 to the second side of the heat insulating component 110, so as to reduce the heat loss of the coil disk 100 during the heating process and improve the heating energy efficiency of the coil disk 100. At the same time, the heat insulating component 110 can also reduce the heat transferred from the coil 1202 to the structure on the second side of the heat insulating component 110, for example, reduce the heat transferred from the coil 1202 to the magnetic member 130, so that the magnetic member 130 can be kept in a lower temperature range during the working process, so as to reduce the possibility of high-temperature demagnetization of the magnetic member 130, thereby improving the reliability of the coil disk 100 and reducing the failure rate of the coil disk 100.

[0101] On this basis, a through hole 112 is provided on the thermal insulation component 110, and the through hole 112 connects the first side and the second side of the thermal insulation component 110. The coil disk 100 also includes an electrical connection component 150, and the electrical connection is at least partially installed on the second side of the thermal insulation component 110. The electrical connection component 150 is used to connect the winding 120 and the circuit board. The power supply circuit can supply power to the winding 120 through the electrical connection component 150, thereby generating thermal radiation and an electromagnetic field through the coil 1202 after being energized.

[0102] In the first case, the electrical connection component 150 extends from the through hole 112 to the first side of the thermal insulation component 110, and is connected to the end of the winding 120 on the first side of the thermal insulation component 110, thereby forming an energized circuit. At this time, the routing of the winding 120 and the routing of the electrical connection component 150 do not interfere with each other, and the electrical connection component 150 located on the second side of the thermal insulation component 110 can freely select the outlet direction of the inner end 1204 or the outlet direction of the outer end 1206 of the spirally wound winding 120 according to needs.

[0103] In the second case, the end of the winding 120 extends to the second side of the thermal insulation component 110 through the through hole 112, and the electrical connection component 150 is connected to the winding 120 passing through the through hole 112 on the second side of the thermal insulation component 110, thereby forming an energized circuit. The heating performance of the coil 1202 is mainly affected by the winding shape on the first side of the thermal insulation component 110. Similarly, at this time, the routing of the winding 120 on the first side of the thermal insulation component 110 and the routing of the electrical connection component 150 on the second side of the thermal insulation component 110 do not interfere with each other. The electrical connection component 150 located on the second side of the thermal insulation component 110 can freely select the outlet direction of the inner end 1204 or the outlet direction of the outer end 1206 of the spirally wound winding 120 according to needs.

[0104] It can be seen that by setting a through hole 112 on the thermal insulation component 110 and setting an electrical connection component 150 on the second side of the thermal insulation component 110 in conjunction with the through hole 112, the inner and outer ends of the winding 120 can be connected separately with the help of the through hole 112, thereby eliminating the possibility of wiring interference between the electrical connection line and the winding 120, thereby solving the technical defect in the related technology that the inner and outer ends 1206 of the winding 120 cannot be connected separately, thereby achieving the technical effect of optimizing the wire output structure of the coil disk 100 and reducing the difficulty of electrical connection of the coil disk 100.

[0105] Specifically, the raw material of the winding 120 wound into the coil 1202 is a high-temperature resistant metal material, and the linear expansion coefficient of the high-temperature resistant metal material is low to avoid high-temperature damage or high-temperature deformation of the coil 1202. Specifically, the coil 1202 can be prepared by copper alloy or iron alloy.

[0106] Specifically, the material of the heat insulating component 110 may be a mixture of white carbon black and moissanite, or may be flexible vacuum silicon heat insulating cotton.

[0107] like Figure 2 , Figure 4 and Figure 6As shown, in some embodiments of the present invention, specifically, the coil disk 100 also includes: a supporting component 140, a first side of the supporting component 140 includes a receiving groove 1402, and the thermal insulation component 110 and the coil 1202 are arranged in the receiving groove 1402; wherein, the supporting component 140 includes a via hole 1404, the via hole 1404 is opposite to the through hole 112, and the electrical connection component 150 or the winding 120 is passed through the through hole 112 and the via hole 1404.

[0108] In this embodiment, the coil disk 100 further includes a support component 140, which is connected to the heat insulating component 110 and can provide support and protection for the heat insulating component 110 and the coil 1202. After power is turned on, the heat radiation generated by the coil 1202 is blocked by the heat insulating component 110 to reduce the working temperature of the support component 140 and prevent the support component 140 from melting at high temperature.

[0109] A receiving groove 1402 is formed on a first side of the supporting component 140 , the receiving groove 1402 faces the cooking device 200 , and the heat insulating component 110 and the coil 1202 are disposed in the receiving groove 1402 .

[0110] On this basis, the electrical connection assembly 150 is arranged on the second side of the support component 140 away from the cooking utensil 200, and the support component 140 is located between the heat insulating component 110 and the electrical connection assembly 150. The support component 140 is provided with a via 1404, and after assembly, the via 1404 is opposite to the through hole 112, and the via 1404 and the through hole 112 are connected to the first side of the heat insulating component 110 and the second side of the support component 140.

[0111] When electrically connecting the winding 120, the winding 120 can extend to the second side of the support component 140 through the through-hole 112 and the via 1404, and the electrical connection component 150 connects the end of the winding 120 on the second side of the support component 140, or the electrical connection component 150 extends from the via 1404 and the through-hole 112 to the first side of the thermal insulation component 110, and the electrical connection component 150 connects the end of the winding 120 on the first side of the thermal insulation component 110.

[0112] It can be seen that by setting the via 1404, the electrical connection component 150 or the end of the winding 120 can cross the support component 140 to complete the electrical connection, so that the electrical connection component 150 is arranged outside the support component 140 on the basis of meeting the requirements of two-end lead-out, avoiding interference between the electrical connection component 150 and the support component 140. In addition, the technical effect of optimizing the structural layout of the coil disk 100, improving the structural compactness of the coil disk 100, and providing convenient conditions for the miniaturization design of the coil disk 100 is achieved.

[0113] like Figure 2 and Figure 6As shown, in some embodiments of the present invention, specifically, the winding 120 is spirally coiled on the first side of the thermal insulation component 110; the winding 120 includes an inner end 1204 and an outer end 1206, the through hole 112 includes a first through hole 1122 and a second through hole 1124, the electrical connection component 150 is connected to the inner end 1204 of the winding 120 through the first through hole 1122, and the electrical connection component 150 is connected to the outer end 1206 of the winding 120 through the second through hole 1124.

[0114] In this embodiment, the winding 120 is spirally wound on the first side of the thermal insulation component 110 to form a spiral coil 1202 that can simultaneously generate thermal radiation and an electromagnetic field, the inner end 1204 of the coil 1202 is located in the central area of ​​the thermal insulation component 110, and the outer end 1206 of the coil 1202 is located in the edge area of ​​the thermal insulation component 110.

[0115] On this basis, a first through hole 1122 and a second through hole 1124 are provided on the thermal insulation component 110. The first through hole 1122 is provided in the central area of ​​the thermal insulation component 110. The electrical connection component 150 is connected to the inner end 1204 of the winding 120 through the first through hole 1122. The second through hole 1124 is provided in the edge area of ​​the thermal insulation component 110. The electrical connection component 150 is connected to the outer end 1206 of the winding 120 through the second through hole 1124, thereby realizing independent output wires at the inner and outer ends of the spiral coil 1202.

[0116] It can be seen that by respectively providing the first through hole 1122 and the second through hole 1124 for the inner and outer ends 1206 of the winding 120, the inner and outer ends 1206 of the winding 120 can be wired out nearby to shorten the wire distance between the end of the winding 120 and the electrical connection assembly 150, thereby improving the structural compactness of the coil disk 100 and providing convenient conditions for the miniaturized design and lightweight design of the coil disk 100.

[0117] like Figure 3 , Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments of the present invention, specifically, the electrical connection component 150 includes: a wire 152, which is arranged on the second side of the thermal insulation component 110; a first terminal 154, which is passed through the through hole 112 and the via 1404, and the first terminal 154 connects the winding 120 and the first end of the wire 152; a second terminal 156, which is connected to the second end of the wire 152, and the second terminal 156 is used to connect the circuit board.

[0118] In this embodiment, the electrical connection assembly 150 includes a wire 152 , a first terminal 154 , and a second terminal 156 .

[0119] The wire 152 is arranged on the second side of the thermal insulation component 110, the first terminal 154 is connected to the first end of the wire 152, the second terminal 156 is connected to the second end of the wire 152, the wire 152 is connected to the winding 120 through the first terminal 154, and the wire 152 is connected to the power supply circuit on the circuit board through the second terminal 156. Specifically, the first terminal 154 can be inserted into the through hole 112 and the via hole 1404 to connect the winding 120 on the first side of the thermal insulation component 110, or the first terminal 154 can be fixed on the second side of the thermal insulation component 110, and the winding 120 passing through the through hole 112 and the via hole 1404 is connected through the first terminal 154.

[0120] This structure realizes independent connection between the winding 120 and both sides of the circuit board by setting the first terminal 154 and the second terminal 156, so that the assembly step and the electrical connection step of the winding 120 can be performed independently, thereby achieving the technical effect of optimizing the structure of the electrical connection component 150, reducing the difficulty of electrical connection, and reducing the assembly complexity of the coil disk 100.

[0121] like Figure 4 , Figure 6 and Fig. 9 As shown, in some embodiments of the present invention, specifically, the wire 152 is at least partially attached to the second side of the support component 140 , and the second terminal 156 is located on the peripheral side of the support component 140 .

[0122] In this embodiment, the wire 152 is at least partially attached to the second side of the support component 140 , and the support component 140 can provide positioning and support for the wire 152 to avoid loosening or deformation of the wire 152 , thereby improving the electrical connection reliability of the coil disk 100 .

[0123] In this case, the second end of the wire 152 extends from the second side of the support component 140 to the peripheral side of the support component 140, thereby realizing the lateral outlet of the coil disk 100 to avoid the wire 152 and the second terminal 156 from occupying the space on the second side of the support component 140, thereby reducing the thickness of the coil disk 100 and providing convenient conditions for the ultra-thin design of the coil disk 100 and the cooking device.

[0124] like Figure 4 and Fig. 9 As shown, in some embodiments of the present invention, specifically, the wire 152 includes: a first wire 1522, the first wire 1522 is connected to the inner end 1204 of the winding 120; a second wire 1524, the second wire 1524 is connected to the outer end 1206 of the winding 120; wherein the first wire 1522 and the second wire 1524 are arranged side by side on the second side of the thermal insulation component 110.

[0125] In this embodiment, the wire 152 includes a first wire 1522 and a second wire 1524. The first wire 1522 is connected to the inner end 1204 of the winding 120 via the first terminal 154, and the first wire 1522 is connected to the power supply circuit on the circuit board via the second terminal 156. The second wire 1524 is connected to the outer end 1206 of the winding 120 via the first terminal 154, and the second terminal 156 is connected to the power supply circuit on the circuit board via the second terminal 156.

[0126] Among them, the first wire 1522 and the second wire 1524 are arranged side by side on the second side of the support part 140, and the first wire 1522 and the second wire 1524 both extend in the radial direction of the coil 1202, wherein the outgoing wire length of the first wire 1522 connected to the inner end 1204 of the winding 120 is longer, and the outgoing wire length of the second wire 1524 connected to the outer end 1206 of the winding 120 is shorter.

[0127] This structure realizes independent wiring of the inner and outer ends 1206 of the winding 120 through the first wire 1522 and the second wire 1524, and improves the structural compactness of the electrical connection component 150 by arranging the first wire 1522 and the second wire 1524 side by side, reduces the space occupied by the electrical connection component 150, and provides convenient conditions for the miniaturization and lightweight design of the coil disk 100.

[0128] like Figure 4 and Figure 5 As shown, in some embodiments of the present invention, specifically, the second side of the support component 140 includes a limiting groove 1406 , and the wire 152 is clamped in the limiting groove 1406 .

[0129] In this embodiment, a limiting groove 1406 is provided on the second side of the support component 140, and the shape and size of the limiting groove 1406 are adapted to the shape and size of the wire 152. Specifically, the limiting groove 1406 can be formed by integrally forming a wire clamp on the second side of the support component 140. During the assembly process, the wire 152 is pressed into the limiting groove 1406 to complete the positioning and installation of the wire 152 on the second side of the support component 140, so as to reduce the possibility of the wire 152 being misplaced or even falling off, thereby achieving the technical effect of improving the positioning accuracy and positioning reliability of the wire 152 and improving the electrical connection reliability of the coil disk 100.

[0130] like Fig. 9 and Fig.10 As shown, in some embodiments of the present invention, specifically, the coil disk 100 further includes: a fixing member 160 connected to the supporting component 140 , and the wire 152 is clamped between the fixing member 160 and the supporting component 140 .

[0131] In this embodiment, the coil disk 100 further includes a fixing member 160, which is disposed on the second side of the support member 140 and connected to the support member 140. During the assembly process, the wire 152 is first placed at a predetermined installation position, and the initial positioning is completed through the limiting groove 1406, and then the wire 152 is clamped on the support member 140 through the fixing member 160 to prevent the wire 152 from being misplaced on the support member 140 or even falling off.

[0132] Specifically, a single fixing member 160 can simultaneously fix the first conductive wire 1522 and the second conductive wire 1524 that are arranged side by side.

[0133] By setting the fixing member 160, the positioning accuracy of the wire 152 can be improved in cooperation with the limiting groove 1406, and the possibility of electrical connection failure caused by looseness and misalignment of the wire 152 can be reduced, thereby reducing the electrical connection failure rate of the coil disk 100 and improving the practicality and reliability of the coil disk 100.

[0134] In some embodiments of the present invention, specifically, the winding 120 is passed through the through hole 112 and the via hole 1404; the winding 120 includes a first section and a second section 1208, the first section is spirally coiled on the first side of the thermal insulation component 110, and the second section 1208 is connected to the electrical connection component 150 on the second side of the support component 140.

[0135] In this embodiment, the winding 120 is inserted into the through hole 112 and the via hole 1404 , and the inner end 1204 and the outer end 1206 of the winding 120 extend to the second side of the thermal insulation component 110 through the through hole 112 and the via hole 1404 .

[0136] On this basis, the winding 120 includes a first section and a second section 1208 . The cross-sectional shape of the first section is rectangular, and the first section is wound into a coil 1202 on the first side of the thermal insulation component 110 .

[0137] The second section 1208 is located on the second side of the thermal insulation component 110 , and the second section 1208 extends toward the peripheral side of the thermal insulation component 110 . The electrical connection assembly 150 is connected to the second section 1208 at the peripheral side of the thermal insulation component 110 .

[0138] Under this structure, the second section 1208 on the winding 120 directly serves as the wire output structure, and the electrical connection component 150 can complete the electrical connection operation between the inner and outer ends 1206 of the winding 120 with the second section 1208 on the second side of the thermal insulation component 110, eliminating the steps of inserting the first terminal 154 into the through hole 112, welding the first terminal 154 by resistance, and arranging the wire 152 on the second side of the thermal insulation component 110, thereby reducing the difficulty of connecting the electrical connection component 150 and the winding 120, thereby achieving the technical effect of reducing the assembly difficulty and complexity of the coil disk 100.

[0139] like Fig.11 and Fig.12 As shown, in some embodiments of the present invention, specifically, the electrical connection assembly 150 further includes: a third terminal 158 connected to the second section 1208 .

[0140] In this embodiment, the electrical connection assembly 150 further includes a third terminal 158 , which is connected to the second section 1208 and is located around the thermal insulation component 110 . The third terminal 158 is used to connect to the power supply circuit on the circuit board.

[0141] It can be seen that under this structure, the assembly of the winding 120 and the output of the winding 120 can be completed simultaneously. Specifically, the first section and the second section 1208 can be formed on the insulation component 110 by split casting, and finally the assembly of the coil disk 100 can be completed by connecting the third terminal 158, thereby achieving the technical effect of reducing the structural complexity of the coil disk 100 and reducing the difficulty of assembling the coil disk 100.

[0142] like Fig.11 and Fig.12 As shown, in some embodiments of the present invention, specifically, the second section 1208 includes a folded section 1209 , and the folded section 1209 is a multi-layer structure in the width direction of the winding 120 .

[0143] In this embodiment, the second section 1208 includes a folded section 1209 , and the folded section 1209 is a multi-layer structure in the width direction of the winding 120 . Specifically, the second section 1208 can be obtained by transversely folding the strip-shaped winding 120 .

[0144] The folded section 1209 formed by folding the winding 120 multiple times can increase the overcurrent capacity of the second section 1208, so that the second section 1208 can meet the power supply requirements of the first section, ensuring that the second section 1208 can replace the function of the wire 152 and contact the winding 120 as the current conduction limit of the outlet structure. This achieves the technical effect of optimizing the structure of the winding 120, widening the power range of the coil disk 100, and enhancing the heating performance of the coil disk 100.

[0145] In some embodiments of the present invention, specifically, the diameter of the through hole 112 is a first diameter, and the range of the first diameter is: greater than or equal to 2.5 mm and less than or equal to 12.5 mm.

[0146] In this embodiment, the diameter of the through hole 112 on the heat insulating component 110 is a first diameter, and the first diameter needs to be greater than or equal to 2.5 mm and less than or equal to 12.5 mm.

[0147] By limiting the first diameter to be greater than or equal to 2.5 mm, it can be ensured that the width of the first terminal 154 or the winding 120 in the through hole 112 can meet the overload current requirement, ensuring that the power supply current that can be conducted matches the heating requirement.

[0148] By limiting the first diameter to be less than or equal to 12.5 mm, it is possible to reduce the damage of the through hole 112 to the thermal insulation component 110 while meeting the power supply demand, ensure that the thermal insulation component 110 has sufficient rigidity, ensure that the thermal insulation component 110 can provide stable and effective support for the coil 1202, and reduce the possibility of the thermal insulation component 110 breaking.

[0149] Specifically, when the coil disk 100 is applied to an induction cooker, the first diameter is greater than or equal to 5 mm and less than or equal to 7 mm.

[0150] In some embodiments of the present invention, specifically, the diameter of the via hole 1404 is a second diameter, and the second diameter is greater than the first diameter; the difference between the second diameter and the first diameter is greater than or equal to 2 mm.

[0151] In this embodiment, the diameter of the via hole 1404 on the thermal insulation component 110 is a second diameter, and the second diameter is larger than the first diameter. Considering that the winding 120 or the first terminal 154 in the via hole 1404 will generate heat, and there will be deviations in the installation of the via hole 1404 and the through hole 112 on the thermal insulation component 110, the second diameter needs to be larger than the first diameter to achieve heat dissipation through the gap formed by the size difference, and compensate for the assembly error through the size difference.

[0152] On this basis, by limiting the difference between the second diameter and the first diameter to be greater than or equal to 2 mm, the damage of the via 1404 to the support component 140 can be reduced while meeting the heat dissipation requirements and assembly error compensation requirements, thereby improving the structural strength of the support component 140 and reducing the failure rate of the support component 140.

[0153] like Figure 4 and Fig. 9 As shown, in some embodiments of the present invention, specifically, the coil disk 100 further includes: a magnetic member 130 , which is disposed on the second side of the heat insulation component 110 , and the magnetic member 130 avoids the electrical connection component 150 .

[0154] In this embodiment, the coil disk 100 further includes a magnetic member 130, which is arranged opposite to the coil 1202 and is located on the side of the coil 1202 away from the cooking utensil 200. By providing the magnetic member 130, the distribution of the electromagnetic field on the side of the coil 1202 away from the cooking utensil 200 can be changed, so that the electromagnetic field generated by the coil 1202 can be concentrated on the side where the cooking utensil 200 is located, so as to heat the cooking utensil 200 in a concentrated manner, thereby achieving the technical effect of improving the electromagnetic heating efficiency and electromagnetic heating energy efficiency.

[0155] The heat insulating component 110 is disposed between the coil 1202 and the magnetic component 130, the first side of the heat insulating component 110 faces the cooking utensil 200, the coil 1202 is disposed on the first side of the heat insulating component 110, the second side of the heat insulating component 110 faces away from the cooking utensil 200, and the magnetic component 130 is disposed on the second side of the heat insulating component 110. The heat insulating component 110 has excellent heat insulating performance, and can reduce the heat diffused from the high-temperature cooking utensil 200 and the high-temperature coil 1202 to the magnetic component 130, so that the magnetic component 130 is kept at a relatively low temperature during operation, and the magnetic component 130 is prevented from losing its magnetism due to high temperature, thereby ensuring the working reliability of the coil disk 100.

[0156] A second aspect of the present invention provides a cooking device, which includes: a body; and a coil disk 100 such as any one of the above embodiments, which is arranged on the body.

[0158] On this basis, the cooking device also includes a main body, which is the main frame structure of the cooking device. The main body is used to position, support and protect other working structures on the cooking device. The coil disk 100 can be set inside the main body, and the coil disk 100 can also be embedded on the top of the main body to heat the cooking utensils 200 placed on the cooking device through the coil disk 100.
