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 coil disk, the heating effect is achieved by the coil wound by the metal winding. The winding needs to be welded to the terminal before it can be connected to the circuit control board. The terminal material is usually brass. Because copper alloy has high electrical conductivity and high thermal conductivity, this makes it easy for heat to spread rapidly during resistance welding, making it difficult to maintain the temperature of the welding area at the required melting temperature.

[0003] In the related art, the position of the terminal is first located by tooling, and then the terminal is welded to the winding on one side. In order to avoid cold solder joints after welding or disconnection of the welding area under high temperature, copper solder paste is finally required for repair welding.

[0004] However, this solution has technical problems such as a complicated welding process, poor welding between the terminal and the metal winding, and the pull-out force and reliability of the single-sided welding not meeting the product's working requirements. 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 present invention 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 present invention provides a coil disk, which includes: a heat insulation component; a winding, which is wound on a first side of the heat insulation component to form a coil, and the coil can generate heat radiation and an electromagnetic field when energized; a terminal, which includes a socket, which is used to clamp the winding, and the terminal is connected to the winding in the socket.

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

[0010] The coil disk includes a winding, which is spirally wound to form a helical coil. When energized, the helical coil generates an electromagnetic field. Due to the coil's internal resistance, the energized coil also radiates heat. The intensity of the electromagnetic field and heat radiation generated by the coil can be adjusted by varying the frequency of the current supplied to the coil.

[0011] 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 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.

[0012] If a non-magnetic cookware is placed above the coil, while the non-magnetic cookware cannot resonate and generate eddy currents in the electromagnetic field, the heat radiation generated by the coil can directly heat the non-magnetic cookware, allowing the food to be cooked by the high-temperature cookware. Furthermore, because the coil generates a large amount of heat radiation, the actual heating effect of the coil on the cookware is not affected by the relocation of the cookware when the user flips the pan, thus simulating the effect of cooking over an open flame.

[0013] The coil disc also includes a thermal insulation component, with a first side of the thermal insulation component facing the cooking vessel, the coil disposed on the first side of the thermal insulation component, and a second side of the thermal insulation component facing away from the cooking vessel. The thermal insulation component exhibits excellent thermal insulation properties, reducing heat transfer from the high-temperature cooking vessel and the high-temperature coil to the second side of the thermal insulation component. This reduces heat loss during heating of the coil disc and improves its heating efficiency.

[0014] On this basis, the coil disk also includes terminals, which are used to connect the windings and wires, thereby connecting the windings to the control circuit via the wires. The terminals are provided with sockets, the shape of which adapts to the outer contour of the windings. During assembly, the terminals can be clamped to the windings via the sockets to achieve pre-positioning of the terminals on the windings, reducing the probability of mis-welding of the terminals. Furthermore, the sockets are an inherent structure of the terminals, and the terminals that are pre-positioned by the sockets do not require the use of tooling for positioning. Compared with related technologies, this reduces the complexity of the welding process.

[0015] Furthermore, compared to the single-sided welding method used in related art, the two sides of the socket can be welded to the two sides of the winding. This double-sided welding method increases the welding area between the winding and the terminal, thereby increasing the welding pull-out force between the winding and the terminal, improving the reliability of the welding process between the winding and the terminal, and reducing the probability of repair welding. In addition, after double-sided welding, the winding and the terminal are bilaterally aligned, which reduces the probability of high-temperature weld failure, and also reduces the probability of subsequent repair welding.

[0016] It can be seen that the present application solves the technical problems existing in the related technology such as the complicated welding process, poor welding of the terminal and the metal winding, and the pulling force and reliability of the single-sided welding not meeting the working requirements of the product by providing a socket on the terminal and realizing pre-positioning and double-sided welding of the terminal through the socket, thereby achieving the technical effect of improving the structural stability of the coil disk and reducing the failure rate of the coil disk.

[0017] Specifically, the raw material of the winding 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 made of copper alloy or iron alloy.

[0018] 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 cotton.

[0019] In addition, the coil disk provided by the present invention may also have the following additional technical features:

[0020] In some technical solutions of the present invention, specifically, the thermal insulation component includes a through hole, and the terminal includes: a conductive sheet, the conductive sheet is passed through the through hole, the socket is located on the conductive sheet, and the winding is welded to the conductive sheet; a wiring part, the wiring part is connected to the conductive sheet, the wiring part is located on the second side of the thermal insulation component, and the wiring part is used to fix the wire to the conductive sheet.

[0021] In this technical solution, a through-hole is provided in the thermal insulation component, connecting the first and second sides of the thermal insulation component. The terminal includes a conductive sheet and a connection portion. The conductive sheet is inserted into the through-hole, with the first end of the conductive sheet located on the first side of the thermal insulation component. The socket is formed at the first end of the conductive sheet, and the second end of the conductive sheet is located on the second side of the thermal insulation component. The connection portion is connected to the second end of the conductive sheet and is used to connect the wire. Specifically, the connection portion can fix the wire to the conductive sheet, allowing the conductive sheet to connect the winding and the wire.

[0022] By setting through holes on the thermal insulation components and setting conductive sheets and wiring parts in conjunction with the through holes, the inner and outer ends of the winding can be connected separately with the help of the through holes, eliminating the possibility of wiring interference between the wires and the windings, thereby achieving the technical effect of reducing the difficulty of wire wiring.

[0023] Specifically, the wiring part includes a metal pressing plate, which is connected to the conductive plate. The cut metal pressing plate can be bent relative to the conductive plate. After the wire is brought into contact with the second end of the conductive plate, the wire can be pressed tightly against the conductive plate by bending the metal pressing plate to prevent the wire from separating from the conductive plate, thereby realizing cold-pressed wiring.

[0024] Specifically, the conductive sheet and the metal pressing sheet are formed through an integral molding process.

[0025] In some technical solutions of the present invention, specifically, the conductive sheet includes: a first section, the first section is passed through the through hole; a bending section, the first end of the bending section is connected to the first section; a second section, the second section is connected to the second end of the bending section, and an insertion is formed between the first section and the second section.

[0026] In this technical solution, the conductive sheet includes a first section, a bent section and a second section.

[0027] Specifically, the first and second sections are straight pieces, the bent section connects the first and second sections, and the second section extends to the circumference of the first section through the bent section. A gap is left between the first and second sections for the winding to be inserted, forming a socket.

[0028] During the assembly process, the winding is first inserted between the first section and the second section, and then the first section is welded to the first side of the winding, and the second section is welded to the second side of the winding, thereby completing double-sided welding.

[0029] Among them, after the winding is inserted into the socket, the first section and the second section can clamp the winding, thereby completing the pre-positioning of the terminal, so that the terminal can be welded without the help of tooling positioning, thereby reducing the difficulty and complexity of welding.

[0030] Furthermore, the first section and the second section can be welded to two sides of the winding respectively, which is beneficial to improving the reliability of welding and reducing the probability of subsequent repair welding.

[0031] In some technical solutions of the present invention, specifically, the socket faces the thermal insulation component; and the bent section is located on the side of the winding facing away from the thermal insulation component.

[0032] In this technical solution, the socket formed between the first section and the second section faces the thermal insulation component. During the assembly process, the first section is first bent to move the socket to the side of the winding facing away from the thermal insulation component, and then the first section is pulled to make the socket sleeved on the outside of the winding to complete the pre-positioning of the conductive sheet on the winding.

[0033] Specifically, when the winding is located above the thermal insulation component, the bent section is pressed against the winding on the side of the winding facing away from the thermal insulation component, so that the conductive sheet can be stuck on the outside of the winding by its own weight, ensuring that the conductive sheet will not fall off the winding, thereby improving the accuracy and reliability of the pre-positioning of the conductive sheet and reducing the difficulty of welding between the conductive sheet and the winding.

[0034] In some technical solutions of the present invention, specifically, one of the first section and the second section includes a protrusion, and the other includes a slot, and the protrusion is engaged with the slot; the protrusion and the slot are located on the side of the winding facing away from the bending section.

[0035] In this technical solution, a protrusion and a slot are provided on the first section and the second section respectively. The shapes of the protrusion and the slot match each other, and the two can be snapped together by pressing the protrusion into the slot.

[0036] It can be seen that the first section and the second section can be pre-pressed together by the protrusion and the slot to prevent the winding from slipping out of the socket between the first section and the second section, thereby achieving the technical effect of improving the pre-positioning reliability of the terminal and improving the assembly accuracy of the terminal.

[0037] Specifically, one protrusion and one slot form a group, and multiple groups of slots and protrusions are provided between the first section and the second section.

[0038] In some technical solutions of the present invention, specifically, the bending section includes a notch, and the notch is connected to the socket.

[0039] In this technical solution, a gap is provided in the bending section, and the gap connects the inside and outside of the socket. After assembly is completed, part of the winding is exposed inside the gap.

[0040] By setting a notch on the bending portion, the bending portion between the first section and the second section can be reduced, thereby reducing the probability of current transmission in the bending portion during the welding process, and increasing the probability of current directly passing through the winding, thereby enabling rapid heating and welding between the winding and the conductive sheet, thereby achieving the technical effect of increasing welding reliability.

[0041] In some technical solutions of the present invention, specifically, the conductive sheet includes: a third section, the third section is passed through the through hole; a fourth section is connected to the third section; a fifth section is connected to the third section, the fourth section and the fifth section are arranged side by side, and a socket is formed between the fourth section and the fifth section.

[0042] In this technical solution, the conductive sheet includes a third section, a fourth section and a fifth section.

[0043] The third section is inserted into the through hole, and the wiring section is connected to the third section. The fourth section and the fifth section are arranged side by side on the third section, and a gap is left between the fourth section and the fifth section, and the gap forms a socket.

[0044] During the assembly process, the fourth section and the fifth section pass through the through hole and are finally clamped on both sides of the winding. This clamping positioning can prevent the terminal from shaking laterally relative to the winding, thereby achieving pre-positioning of the terminal, thereby eliminating the operation of positioning the conductive sheet through tooling before welding, and thus achieving the technical effect of reducing the complexity and difficulty of welding.

[0045] During the welding process, the fourth section is welded to the first side of the winding, and the fifth section is welded to the second side of the winding, thereby achieving bilateral welding between the winding and the terminal, thereby achieving the technical effect of improving welding reliability and reducing the probability of subsequent repair welding.

[0046] Specifically, the fourth section and the fifth section are distributed in a V-shape.

[0047] In some technical solutions of the present invention, specifically, the socket faces away from the heat insulation component; and the width of the socket gradually decreases in the depth direction of the socket.

[0048] In this technical solution, the direction of the socket is opposite to the direction of the heat insulation component, so that the fourth section and the fifth section can be directly clamped on the winding outside the through hole after passing through the through hole.

[0049] On this basis, the width of the socket gradually decreases in the depth direction, that is, the socket is wide on the outside and narrow on the inside. By setting up a socket with a wide outside and narrow inside, on the one hand, the outer width of the socket can be used to facilitate the winding to be inserted into the socket, avoiding the winding being stuck on the outside of the socket and unable to be inserted. On the other hand, the narrow inside of the socket can be used to allow the winding to be firmly fixed on the inside of the socket, thereby improving the pre-positioning accuracy of the terminal on the winding and further improving the welding reliability between the terminal and the winding.

[0050] In some technical solutions of the present invention, specifically, the fourth section and the fifth section include a first posture and a second posture; when the fourth section and the fifth section are in the first posture, there is an angle between the fourth section and the winding, and there is an angle between the fifth section and the winding; when the fourth section and the fifth section are in the second posture, the fourth section and the fifth section are in contact with the winding.

[0051] In this technical solution, the fourth section and the fifth section are both sheet-shaped, and the fourth section and the fifth section can be bent relative to the third section, so that the fourth section and the fifth section can change their posture by bending.

[0052] Specifically, the fourth section and the fifth section include a first posture and a second posture.

[0053] During the pre-assembly process of the winding and the terminal, the fourth section and the fifth section are in a first posture. In the first posture, the fourth section and the fifth section are open, and there is an angle between the fourth section and the fifth section and the winding, that is, the fourth section and the fifth section are inclined relative to the winding to ensure that the winding can be smoothly inserted into the socket between the fourth section and the fifth section.

[0054] Before welding is required, the fourth section and the fifth section are bent toward the direction of the winding, so that the fourth section and the fifth section are gradually closed until the fourth section and the fifth section are tightly fitted on both sides of the winding. The fourth section and the fifth section can be smoothly switched to the second posture. By making the fourth section and the fifth section tightly fit on both sides of the winding, the welding area between the terminal and the winding can be increased, thereby improving the stability and reliability of the welding between the terminal and the winding, reducing the probability of subsequent repair welding, and achieving the technical effect of improving the stability of the coil disk structure.

[0055] In some technical solutions of the present invention, specifically, the winding is sheet-shaped and is coiled along the length direction to form a coil; the winding can be inserted into the socket along the width direction, and the socket is used to clamp the winding in the thickness direction of the winding.

[0056] In this technical solution, the winding is in sheet form, that is, the winding is larger in width and smaller in thickness, wherein the winding is wound along its length to form a spiral coil to meet heating requirements.

[0057] On this basis, during the installation of the terminal block, the winding can be inserted into the terminal block's socket along its width, allowing the terminal block to be fitted over the outside of the winding. After the terminal block is fitted over the outside of the winding through the socket, the two inner walls of the socket apply pressure to the two sides of the winding in the direction of the winding's thickness, completing the clamping and positioning of the winding, allowing the terminal block to be initially positioned on the winding. Finally, the two sides of the winding can be welded to the two inner walls of the socket through a welding process.

[0058] Thus, the present application solves the technical problems existing in the related art, such as the complicated welding process, poor welding between the terminal and the metal winding, and the failure of the pull-out force and reliability of the single-sided welding to meet the working requirements of the product, by providing a socket on the terminal and achieving pre-positioning and double-sided welding of the terminal through the socket. This solves the technical problems existing in the related art, such as the complicated welding process, poor welding between the terminal and the metal winding, and the failure of the single-sided welding to meet the working requirements of the product. This further achieves the technical effect of improving the structural stability of the coil disk and reducing the failure rate of the coil disk. In addition, by setting the winding in a sheet shape, the contact area between the winding and the terminal can be increased, thereby improving the reliability of welding.

[0059] A second aspect of the present invention provides a cooking device, which includes: a main body; and a coil disk such as that in any of the above technical solutions, which is arranged on the main body.

[0060] This technical solution proposes a cooking device equipped with the coil disk described in any of the above-mentioned technical solutions. Therefore, this cooking device possesses the advantages and can achieve the technical effects achieved by the coil disk described in any of the above-mentioned technical solutions. To avoid repetition, further details will be omitted here.

[0061] 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

[0084] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0085] 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 scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0086] Refer to the following Figures 1 to 18 Coil pans and cooking devices according to some embodiments of the present invention are described.

[0087] like Figure 1 、 Figure 2 、 Figure 3 and Figure 6 As shown, an embodiment of the present invention provides a coil disk 100, which includes: a heat insulating component 110; a winding 120, wherein the winding 120 is wound on a first side of the heat insulating component 110 to form a coil, and the coil can generate heat radiation and an electromagnetic field when energized; a terminal 130, wherein the terminal 130 includes a socket 1302, and the socket 1302 is used to clamp the winding 120, and the terminal 130 is connected to the winding 120 in the socket 1302.

[0088] Figure 1 In FIG, arrow a shows the transfer direction of heat radiation.

[0089] Figure 6 In FIG, arrow b shows the welding direction.

[0090] The present application defines a coil disk 100 , which has electromagnetic heating functions and thermal radiation heating functions.

[0091] Coil disk 100 includes a winding 120, which is spirally wound to form a helical coil. When energized, the helical coil generates an electromagnetic field. Due to the coil's internal resistance, the energized coil also generates heat radiation. The intensity of the electromagnetic field and heat radiation generated by the coil can be adjusted by varying the frequency of the coil's supply current.

[0092] 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 gradually heats up, so that food can be cooked by the high-temperature cooking utensil 200. At the same time, the heat radiation generated by the coil can also provide auxiliary heating for the magnetic cooking utensil 200 to increase the heating power.

[0093] If a non-magnetic cooking utensil 200 is placed above 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 can directly heat the non-magnetic cooking utensil 200, thereby cooking the food using the high-temperature cooking utensil 200. Furthermore, because the coil generates a large amount of heat radiation, the actual heating effect of the coil disk 100 on the cooking utensil 200 is not affected by the relocation of the cooking utensil 200 when the user flips the pot, thus simulating the effect of cooking over an open flame.

[0094] Coil disk 100 also includes a thermal insulation member 110. A first side of thermal insulation member 110 faces cooking vessel 200, and the coil is positioned on the first side of thermal insulation member 110. A second side of thermal insulation member 110 faces away from cooking vessel 200. Thermal insulation member 110 exhibits excellent thermal insulation properties, reducing heat transfer from high-temperature cooking vessel 200 and the high-temperature coil to the second side of thermal insulation member 110. This reduces heat loss during heating of coil disk 100 and improves heating efficiency of coil disk 100.

[0095] On this basis, coil disk 100 also includes a terminal block 130, which is used to connect winding 120 and wire 140, thereby connecting winding 120 to the control circuit via wire 140. Terminal block 130 is provided with a socket 1302, the shape of which matches the outer contour of winding 120. During assembly, terminal block 130 can be clamped onto winding 120 via socket 1302, pre-positioning terminal block 130 on winding 120 and reducing the probability of incorrect soldering of terminal block 130. Furthermore, socket 1302 is an inherent structure of terminal block 130. Pre-positioning terminal block 130 via socket 1302 eliminates the need for tooling for positioning, reducing the complexity of the welding process compared to related art.

[0096] Furthermore, compared to the single-sided welding method used in related art, the two sides of the socket 1302 can be welded to the two sides of the winding 120. This double-sided welding method can increase the welding area between the winding 120 and the terminal 130, thereby increasing the welding pull-out force between the winding 120 and the terminal 130, improving the reliability of the welding process between the winding 120 and the terminal 130, and reducing the probability of repair welding. In addition, after double-sided welding, the winding 120 and the terminal 130 are bilaterally aligned, which reduces the probability of high-temperature weld failure, and also reduces the probability of subsequent repair welding.

[0097] It can be seen that the present application solves the technical problems existing in the related art such as the complicated welding process, poor welding between the terminal 130 and the metal winding 120, and the pulling force and reliability of the single-sided welding not meeting the working requirements of the product by providing a socket 1302 on the terminal 130 and realizing pre-positioning and double-sided welding of the terminal 130 through the socket 1302, thereby achieving the technical effect of improving the structural stability of the coil disk 100 and reducing the failure rate of the coil disk 100.

[0098] Specifically, the raw material of the winding 120 is a high-temperature resistant metal material with a low linear expansion coefficient to avoid high-temperature damage or deformation of the coil. Specifically, the coil can be made of copper alloy or iron alloy.

[0099] 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.

[0100] like Figure 1 、 Figure 2 and Figure 5 As shown, in some embodiments of the present invention, specifically, the thermal insulation component 110 includes a through hole 1102, and the terminal 130 includes: a conductive sheet 132, the conductive sheet 132 is passed through the through hole 1102, the socket 1302 is located on the conductive sheet 132, and the winding 120 is welded to the conductive sheet 132; a wiring portion 134, the wiring portion 134 is connected to the conductive sheet 132, the wiring portion 134 is located on the second side of the thermal insulation component 110, and the wiring portion 134 is used to fix the wire 140 to the conductive sheet 132.

[0101] In this embodiment, a through hole 1102 is provided on the thermal insulation component 110, connecting the first side and the second side of the thermal insulation component 110. The terminal 130 includes a conductive sheet 132 and a connection portion 134. The conductive sheet 132 is inserted into the through hole 1102, with a first end of the conductive sheet 132 located on the first side of the thermal insulation component 110. The socket 1302 is formed at the first end of the conductive sheet 132, and a second end of the conductive sheet 132 is located on the second side of the thermal insulation component 110. The connection portion 134 is connected to the second end of the conductive sheet 132 and is used to connect the wire 140. Specifically, the connection portion 134 can fix the wire 140 to the conductive sheet 132, allowing the conductive sheet 132 to connect the winding 120 and the wire 140.

[0102] By setting a through hole 1102 on the thermal insulation component 110, and setting a conductive sheet 132 and a wiring portion 134 in conjunction with the through hole 1102, the inner and outer ends of the winding 120 can be connected to the through hole 1102 respectively, eliminating the possibility of wiring interference between the wire 140 and the winding 120, thereby achieving the technical effect of reducing the difficulty of wiring the wire 140.

[0103] Specifically, the wiring portion 134 includes a metal pressing plate, which is connected to the conductive plate 132. The cut metal pressing plate can be bent relative to the conductive plate 132. After the wire 140 is brought into contact with the second end of the conductive plate 132, the wire 140 can be pressed tightly against the conductive plate 132 by bending the metal pressing plate to prevent the wire 140 from separating from the conductive plate 132, thereby realizing cold-pressed wiring.

[0104] Specifically, the conductive sheet 132 and the metal pressing sheet are formed through an integral molding process.

[0105] like Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, in some embodiments of the present invention, specifically, the conductive sheet 132 includes: a first section 1321, the first section 1321 is passed through the through hole 1102; a bending section 1322, the first end of the bending section 1322 is connected to the first section 1321; a second section 1323, the second section 1323 is connected to the second end of the bending section 1322, and a socket 1302 is formed between the first section 1321 and the second section 1323.

[0106] In this embodiment, the conductive sheet 132 includes a first section 1321 , a bent section 1322 , and a second section 1323 .

[0107] Specifically, the first section 1321 and the second section 1323 are straight pieces, the bent section 1322 is connected between the first section 1321 and the second section 1323, and the second section 1323 extends through the bent section 1322 to the circumference of the first section 1321. A gap is left between the first section 1321 and the second section 1323 for inserting the winding 120, and this gap forms the socket 1302.

[0108] During the assembly process, the winding 120 is first inserted between the first section 1321 and the second section 1323, and then the first section 1321 is welded to the first side of the winding 120, and the second section 1323 is welded to the second side of the winding 120, thereby completing double-sided welding.

[0109] Among them, after the winding 120 is inserted into the socket 1302, the first section 1321 and the second section 1323 can clamp the winding 120, thereby completing the pre-positioning of the terminal 130, so that the terminal 130 can be welded without the help of tooling positioning, thereby reducing the difficulty and complexity of welding.

[0110] Furthermore, the first section 1321 and the second section 1323 can be welded to two sides of the winding 120 respectively, which is beneficial to improving the reliability of welding and reducing the probability of subsequent repair welding.

[0111] like Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, in some embodiments of the present invention, specifically, the socket 1302 faces the thermal insulation component 110 ; the bent section 1322 is located on the side of the winding 120 facing away from the thermal insulation component 110 .

[0112] In this embodiment, the socket 1302 formed between the first section 1321 and the second section 1323 faces the thermal insulation component 110. During the assembly process, the socket 1302 is first moved to the side of the winding 120 facing away from the thermal insulation component 110 by bending the first section 1321, and then the socket 1302 is sleeved on the outside of the winding 120 by pulling the first section 1321 to complete the pre-positioning of the conductive sheet 132 on the winding 120.

[0113] Specifically, when the winding 120 is located above the thermal insulation component 110, the bent section 1322 abuts against the winding 120 on the side of the winding 120 facing away from the thermal insulation component 110, so that the conductive sheet 132 can be stuck on the outside of the winding 120 by its own weight, ensuring that the conductive sheet 132 will not fall off the winding 120, thereby improving the accuracy and reliability of the pre-positioning of the conductive sheet 132 and reducing the difficulty of welding between the conductive sheet 132 and the winding 120.

[0114] like Figure 7 、 Figure 8 and Figure 9 As shown, in some embodiments of the present invention, specifically, one of the first section 1321 and the second section 1323 includes a protrusion 1324, and the other includes a slot 1325, and the protrusion 1324 is engaged with the slot 1325; the protrusion 1324 and the slot 1325 are located on the side of the winding 120 that is away from the bending section 1322.

[0115] Figure 9 In FIG, arrow b shows the welding direction.

[0116] In this embodiment, a protrusion 1324 and a slot 1325 are respectively provided on the first section 1321 and the second section 1323. The shapes of the protrusion 1324 and the slot 1325 are adapted to each other. By pressing the protrusion 1324 into the slot 1325, the two can be snapped together.

[0117] It can be seen that the first section 1321 and the second section 1323 can be pre-pressed together by the protrusion 1324 and the slot 1325 to prevent the winding 120 from slipping out of the socket 1302 between the first section 1321 and the second section 1323, thereby achieving the technical effect of improving the pre-positioning reliability of the terminal block 130 and improving the assembly accuracy of the terminal block 130.

[0118] Specifically, one protrusion 1324 and one locking groove 1325 constitute a group, and multiple groups of locking grooves 1325 and protrusions 1324 are provided between the first section 1321 and the second section 1323 .

[0119] like Figure 10 、 Figure 11 、 Figure 12 and Figure 13As shown, in some embodiments of the present invention, specifically, the bending section 1322 includes a notch 1326 , and the notch 1326 is communicated with the socket 1302 .

[0120] Figure 12 In FIG, arrow b shows the welding direction.

[0121] Figure 13 In FIG, arrow c shows the direction of current flow during welding.

[0122] In this embodiment, a notch 1326 is formed in the bending section 1322 , and the notch 1326 connects the inside and outside of the socket 1302 . After assembly, part of the winding 120 is exposed inside the notch 1326 .

[0123] By setting a notch 1326 on the bending portion, the bending portion between the first section 1321 and the second section 1323 can be reduced, thereby reducing the probability of current transmission in the bending portion during the welding process, and increasing the probability of current directly passing through the winding 120, thereby enabling rapid heating and welding between the winding 120 and the conductive sheet 132, thereby achieving the technical effect of increasing welding reliability.

[0124] like Figure 14 、 Figure 15 、 Figure 16 and Figure 17 As shown, in some embodiments of the present invention, specifically, the conductive sheet 132 includes: a third section 1327, the third section 1327 is passed through the through hole 1102; a fourth section 1328 is connected to the third section 1327; a fifth section 1329 is connected to the third section 1327, the fourth section 1328 and the fifth section 1329 are arranged side by side, and a socket 1302 is formed between the fourth section 1328 and the fifth section 1329.

[0125] Figure 16 In FIG, arrow b shows the welding direction.

[0126] In this embodiment, the conductive sheet 132 includes a third section 1327 , a fourth section 1328 , and a fifth section 1329 .

[0127] The third section 1327 is inserted into the through hole 1102, and the connection portion 134 is connected to the third section 1327. The fourth section 1328 and the fifth section 1329 are arranged side by side on the third section 1327, with a gap between the fourth section 1328 and the fifth section 1329, which forms the socket 1302.

[0128] During the assembly process, the fourth section 1328 and the fifth section 1329 pass through the through hole 1102 and are finally clamped on both sides of the winding 120. This clamping positioning can prevent the terminal 130 from shaking laterally relative to the winding 120, thereby achieving pre-positioning of the terminal 130, thereby eliminating the operation of positioning the conductive sheet 132 through tooling before welding, thereby achieving the technical effect of reducing the complexity and difficulty of welding.

[0129] During the welding process, the fourth section 1328 is welded to the first side of the winding 120, and the fifth section 1329 is welded to the second side of the winding 120, thereby achieving bilateral welding between the winding 120 and the terminal 130, thereby achieving the technical effect of improving welding reliability and reducing the probability of subsequent repair welding.

[0130] Specifically, the fourth section 1328 and the fifth section 1329 are distributed in a V-shape.

[0131] like Figure 15 As shown, in some embodiments of the present invention, specifically, the socket 1302 faces away from the thermal insulation component 110; in the depth direction of the socket 1302 ( Figure 15 (as shown by the arrow g in the figure), the width of the socket 1302 gradually decreases.

[0132] In this embodiment, the direction of the socket 1302 is opposite to the direction of the thermal insulation component 110, so that the fourth section 1328 and the fifth section 1329 can be directly clamped on the winding 120 outside the through hole 1102 after passing through the through hole 1102.

[0133] On this basis, the width of the socket 1302 gradually decreases in the depth direction of the socket 1302, that is, the socket 1302 is wide on the outside and narrow on the inside. By setting up the socket 1302 with a wide outside and narrow inside, on the one hand, the outer width of the socket 1302 can be used to smoothly insert the winding 120 into the socket 1302, thereby preventing the winding 120 from being stuck outside the socket 1302 and being unable to be inserted. On the other hand, the narrow inner side of the socket 1302 can be used to firmly lock the winding 120 inside the socket 1302, thereby improving the pre-positioning accuracy of the terminal 130 on the winding 120 and further improving the welding reliability between the terminal 130 and the winding 120.

[0134] like Figure 14 、 Figure 15 、 Figure 16 and Figure 17As shown, in some embodiments of the present invention, specifically, the fourth section 1328 and the fifth section 1329 include a first posture and a second posture; when the fourth section 1328 and the fifth section 1329 are in the first posture, there is an angle between the fourth section 1328 and the winding 120, and there is an angle between the fifth section 1329 and the winding 120; when the fourth section 1328 and the fifth section 1329 are in the second posture, the fourth section 1328 and the fifth section 1329 are in contact with the winding 120.

[0135] Figure 14 and Figure 16 , the fourth section 1328 and the fifth section 1329 are in the first posture.

[0136] Figure 17 , the fourth section 1328 and the fifth section 1329 are in the second posture.

[0137] In this embodiment, the fourth section 1328 and the fifth section 1329 are both sheet-shaped, and the fourth section 1328 and the fifth section 1329 can be bent relative to the third section 1327, so that the fourth section 1328 and the fifth section 1329 can change their posture by bending.

[0138] Specifically, the fourth section 1328 and the fifth section 1329 include a first posture and a second posture.

[0139] During the pre-assembly process of the winding 120 and the terminal 130, the fourth section 1328 and the fifth section 1329 are in a first posture. In the first posture, the fourth section 1328 and the fifth section 1329 are open, and there is an angle between the fourth section 1328 and the fifth section 1329 and the winding 120, that is, the fourth section 1328 and the fifth section 1329 are inclined relative to the winding 120 to ensure that the winding 120 can be smoothly inserted into the socket 1302 between the fourth section 1328 and the fifth section 1329.

[0140] Before welding is required, the fourth section 1328 and the fifth section 1329 are bent toward the direction of the winding 120, so that the fourth section 1328 and the fifth section 1329 are gradually closed until the fourth section 1328 and the fifth section 1329 are tightly fitted on both sides of the winding 120, and the fourth section 1328 and the fifth section 1329 can be smoothly switched to the second posture. By making the fourth section 1328 and the fifth section 1329 tightly fit on both sides of the winding 120, the welding area between the terminal 130 and the winding 120 can be increased, thereby improving the stability and reliability of the welding between the terminal 130 and the winding 120, reducing the probability of subsequent repair welding, and achieving the technical effect of improving the structural stability of the coil disk 100.

[0141] like Figure 5 As shown, in some embodiments of the present invention, specifically, the winding 120 is in a sheet shape, and the winding 120 is arranged along the length direction ( Figure 5 The winding 120 can be wound along the width direction ( Figure 5 The socket 1302 is inserted into the socket 1302 in the thickness direction of the winding 120 ( Figure 5 The winding 120 is clamped on the upper surface (as shown by the arrow f).

[0142] In this embodiment, the winding 120 is in a sheet shape, that is, the winding 120 is larger in width and smaller in thickness. The winding 120 is wound along its length to form a spiral coil to meet heating requirements.

[0143] On this basis, during the installation of the terminal block 130, the winding 120 can be inserted into the socket 1302 of the terminal block 130 along its width, allowing the terminal block 130 to be fitted over the outside of the winding 120. After the terminal block 130 is fitted over the outside of the winding 120 through the socket 1302, the two inner walls of the socket 1302 apply pressure to the two surfaces of the winding 120 in the thickness direction of the winding 120, completing the clamping and positioning of the winding 120 and allowing the terminal block 130 to be initially positioned on the winding 120. Finally, the two surfaces of the winding 120 can be welded to the two inner walls of the socket 1302 through a welding process.

[0144] Thus, the present application solves the technical problems existing in the related art, such as the complicated welding process, poor welding between the terminal 130 and the metal winding 120, and the failure of the pull-out force and reliability of the single-sided welding to meet the working requirements of the product, by providing the socket 1302 on the terminal 130 and achieving pre-positioning and double-sided welding of the terminal 130 through the socket 1302. This solves the technical problems existing in the related art, such as the complicated welding process, poor welding between the terminal 130 and the metal winding 120, and the failure of the single-sided welding to meet the working requirements of the product. This further achieves the technical effect of improving the structural stability of the coil disk 100 and reducing the failure rate of the coil disk 100. In addition, by configuring the winding 120 in a sheet shape, the contact area between the winding 120 and the terminal 130 can be increased, thereby improving the reliability of welding.

[0145] Specifically, the width of the socket 1302 is greater than or equal to the thickness of the winding 120 , and the depth of the socket 1302 is greater than or equal to the width of the winding 120 .

[0146] like Figure 18 As shown, an embodiment of the present invention provides a cooking device 300 , which includes: a body 310 ; and a coil disk 100 such as in any of the above embodiments, which is disposed on the body 310 .

The coil disk 100 can be set inside the main body 310, and the coil disk 100 can also be embedded on the top of the main body 310 to heat the cooking utensils 200 placed on the cooking device 300 through the coil disk 100.
