[0001] This application claims priority from a Chinese patent application bearing application number 202223011976.8, filed on November 11, 2022, the entire contents of which are incorporated herein by reference.

[0002] The present application relates to the technical field of heating, and in particular to a coil panel sheet, a coil panel assembly, a lid assembly, and a cooking appliance. [Background technology]

[0003] In conventional coil panel assemblies, in order to increase the power of the coil panel assembly, multiple layers of coils are often wound on the same coil panel sheet. In such coil panel structures, the coils must be wound layer by layer, resulting in relatively low manufacturing efficiency. Summary of the Invention [Problem to be solved by the invention]

[0004] A primary object of the present application is to provide a coil panel sheet, a coil panel assembly, a lid assembly, and a cooking utensil for improving the manufacturing efficiency of a coil panel assembly having a double-layer coil structure. [Means for solving the problem]

[0005] In order to achieve the above object, the present application proposes a coil panel sheet, which includes at least two oppositely arranged coil braces, and the two oppositely arranged coil braces are removably connected.

[0006] In one embodiment of the present application, each of the coil braces is provided with a winding surface, and at least one of the winding surfaces has a convex winding portion.

[0007] In this configuration, the coil can be placed on the winding surface and positioned at the winding portion, making it easier to wind the coil.

[0008] In one embodiment of the present application, the two coil braces are defined as a first coil brace and a second coil brace, respectively, the winding surfaces of the first coil brace and the second coil brace are arranged opposite to each other, and both have convex winding portions, The winding portion provided on the first coil brace is a first winding portion, and the winding portion provided on the second coil brace is a second winding portion, and the first winding portion and the second winding portion are arranged opposite each other.

[0009] Such a configuration allows for easy installation, removal and maintenance of the coil panel assembly.

[0010] In one embodiment of the present application, the first coil brace further includes a partition portion, and the partition portion extends outward from the first winding portion along a radial direction of the first coil brace, The partition portion is spaced apart from the winding surface of the first coil brace to form a first winding gap, and is spaced apart from the winding surface of the second coil brace to form a second winding gap.

[0011] In this configuration, the coils on the two winding surfaces do not interfere with each other when being wound, and the partition portion presses the coils, improving the structural stability of the coils.

[0012] In one embodiment of the present application, the width of the partition gradually increases toward the radial outside of the first coil brace, the central angle of the partition is 180° or less, and the outer edge of the partition does not extend beyond the edge of the first coil brace.

[0013] In this configuration, as the diameter of the coil increases, the width of the partition increases accordingly, thereby allowing the coil to be pushed or partitioned more reliably.

[0014] In one embodiment of the present application, the first winding portion is provided in the center of the first coil brace, and multiple partition portions are provided, and the multiple partition portions are located at the same height of the first winding portion and are arranged at intervals along the circumferential direction of the first coil brace.

[0015] In this configuration, the effect of separating and fixing the coils is further improved.

[0016] In one embodiment of the present application, a plurality of first heat dissipation holes are provided in the first coil brace, and each of the first heat dissipation holes is disposed opposite one of the partition portions.

[0017] In this configuration, the heat dissipation efficiency of the coil panel assembly can be improved.

[0018] In one embodiment of the present application, the second coil brace is provided with a plurality of second heat dissipation holes, The second heat dissipation holes are provided on the outer circumferential side of the second winding portion and spaced apart along the circumferential direction of the second coil brace, and two adjacent second heat dissipation holes are separated by a separating rib.

[0019] In this configuration, the heat dissipation efficiency of the coil panel assembly can be improved.

[0020] In one embodiment of the present application, the first coil brace further includes a plurality of partition portions, the plurality of partition portions being arranged at intervals along a circumferential direction of the first coil brace, and the partition portions extending outward from the first winding portion along a radial direction of the first coil brace, The separating ribs and the partitions are arranged at different positions in the circumferential direction of the coil panel sheet.

[0021] As a result, the heat dissipation gaps between adjacent partitions and the second heat dissipation holes between adjacent isolating ribs are positioned at staggered positions, so that a heat dissipation path exists at any position of the coil, improving the heat dissipation efficiency of the coil panel assembly and making it easier to fix two coil braces arranged opposite each other.

[0022] And / or, each separating rib may have a crimping protrusion on the side opposite the first coil brace, which can firmly hold components such as a warming plate of the cookware, improving the stability of the entire cookware structure.

[0023] In one embodiment of the present application, the second winding portion is provided with an insertion hole, and a part of the first winding portion is inserted into the insertion hole.

[0024] In this configuration, the first coil brace and the second coil brace can be positioned in the surface direction of the coil panel sheet, thereby improving the structural stability of the coil panel sheet and, in addition, the connection structure is simple and assembly is easy.

[0025] In one embodiment of the present application, the first wrapping portion includes a wrapping section and an insertion section connected to each other, The winding section is provided protruding from the surface of the first winding brace, the insertion section is provided protruding from the surface of the winding section facing the second coil brace and is inserted into the insertion hole, and the end face of the winding section abuts the end face of the second winding section.

[0026] In such a configuration, the distance between the two winding surfaces can be precisely defined, leaving an adequate winding gap for winding.

[0027] In one embodiment of the present application, a first mounting hole is provided in the first coil brace, a second mounting hole is provided in the second coil brace, and the second mounting hole and the first mounting hole are arranged opposite each other, The coil panel further includes a locking member that is inserted through the first mounting hole and the second mounting hole to connect the first coil brace and the second coil brace.

[0028] The strength of the connection between the first coil brace and the second coil brace is reinforced by the connection structure using the locking member and the mounting hole, and attachment and detachment are also made easy.

[0029] And / or, the distance d between the two winding surfaces satisfies 0.8 mm≦d≦2 mm. In order to leave an appropriate winding gap for winding, the range of the distance between the two winding surfaces is specifically limited, and the coil panel sheet is not too thick.

[0030] In one embodiment of the present application, the coil panel sheet is provided with a brace hole that passes through the two coil braces and the winding portion. The brace hole improves the heat dissipation efficiency of the coil panel assembly and also serves as a relief space for attaching other components of the cookware.

[0031] And / or, the coil panel sheet further includes a wire stop clip, the wire stop clip being provided on an edge of one of the coil braces, and the wire stop clip being provided with at least two wire stop grooves, which is advantageous in fixing the coil lead wire during coil winding, maintaining the structural stability of the wound coil, improving the yield of the coil panel assembly, and reducing the defective rate of produced parts.

[0032] And / or, an extension portion is provided on the periphery of one of the coil braces to fix the coil panel sheet, thereby fixing the coil panel assembly in the cooking appliance.

[0033] And / or, one of the coil braces may be provided with a connection hole through which a connection member passes to fix the coil panel sheet, which is advantageous for fixing the coil panel assembly in the cooking appliance.

[0034] The present application also proposes a coil panel assembly including at least two layers of coils and any of the coil panel sheets described above, wherein the at least two layers of coils are wound around two coil braces of the coil panel sheet, and each of the coil braces is provided with at least one layer of the coils.

[0035] The present application also proposes a lid assembly including a lid and the coil panel assembly, wherein a chamber is formed in the lid, and the coil panel assembly is disposed in the chamber.

[0036] The present application also proposes a cooking utensil including an utensil body and the lid assembly, the lid assembly being attached to the utensil body. [Effects of the Invention]

[0037] In the technical solution of the present application, the coil panel sheet is configured by combining at least two coil braces, and the two coil braces arranged opposite each other are removably connected. With this configuration, when winding the coils, the two coil braces can be disassembled, and the coils can be wound on each of the two coil braces, and then these can be stacked and combined. This eliminates the need to wind the coils layer by layer as in conventional structures, thereby improving the manufacturing efficiency of the coil panel assembly.

[0045] The present application proposes a coil panel sheet 10.

[0046] Referring to Figures 1 and 3, in some embodiments of the coil panel sheet 10 of the present application, the coil panel sheet 10 includes at least two oppositely arranged coil braces 11, and the two oppositely arranged coil braces 11 are removably connected.

[0047] The coil panel sheet 10 proposed herein primarily functions as a base for receiving the coil panel assembly 100, around which the coil 30 is wound. A typical coil panel assembly 100 has a winding surface or a spiral winding groove for placing the coil 30. When multiple layers of coils 30 are provided in the coil panel assembly 100, the coils 30 must be wound layer by layer around the coil surface or winding groove. Meanwhile, the coil panel sheet 10 proposed herein has at least two coil braces 11, which are arranged opposite each other and removably connected. It can be understood that the first coil brace 111 and the second coil brace 113 are removable so as to be separated from each other. In this case, when winding the coil 30, the two coil braces 11 can be disassembled, and the coil 30 can be wound around each of the two coil braces 11, and then stacked and combined. Compared with manufacturing methods such as winding layer by layer, this improves the efficiency of winding the coil 30 and the manufacturing efficiency of the coil panel assembly 100. When it is necessary to dismantle the entire coil panel assembly 100, the two coil braces 11 may be directly separated to efficiently remove the coil 30, thus improving the convenience of dismantling the coil panel assembly 100.

[0048] In one embodiment of the present application, the means for detachably connecting the two coil braces 11 may be, but is not limited to, a clip connection, a bolt connection, a screw connection, adhesive connection, or the like. The outline of the coil brace 11 may be circular, semicircular, rectangular, or another polygonal shape, and may be set depending on the number of turns and size of the coil 30 to be wound, the structure of the coil panel assembly 100 at the installation position, and the like.

[0049] Therefore, as can be understood, in the technical solution of the present application, the coil panel sheet 10 is configured by combining at least two coil braces 11, and the two coil braces 11 arranged opposite each other are removably connected, so that in this configuration, when winding the coil 30, the two coil braces 11 can be disassembled, and the coil 30 can be wound around each of the two coil braces 11, and then these can be stacked and combined, eliminating the need to wind the coil 30 layer by layer as in conventional structures, thereby improving the manufacturing efficiency of the coil panel assembly 100.

[0050] Referring to FIG. 4, in some embodiments of the coil panel sheet 10 of the present application, each of the coil braces 11 is provided with a winding surface, and at least one of the winding surfaces has a winding portion 13 protruding therefrom.

[0051] In one embodiment of the present application, each coil brace 11 is provided with a winding surface. The coil brace 11 has a generally disk-shaped structure and two opposite surfaces. Either of the two surfaces may be the winding surface, or only one of the surfaces may be the winding surface. For example, the opposing surfaces or the opposing surfaces of the two coil braces 11 may be the winding surface, but this is not limited thereto. By providing the winding surfaces, the coil 30 can be placed on the winding surface, reducing the risk of the coil 30 collapsing and improving the convenience of winding the coil 30.

[0052] Furthermore, a winding portion 13 may be provided in a protruding manner on the winding surface, and the winding portion 13 is generally provided in the center of the coil brace 11. In this case, the coil 30 is positioned by the winding portion 13, and the coil can be wound using the winding portion 13 as a winding base, thereby improving convenience when winding the coil 30. Note that in one embodiment of the present application, the winding portion 13 may be provided in a protruding manner on the winding surface of each coil brace 11, or may be provided in a protruding manner on only one winding surface, and this may be set depending on the structure of the mounting position, the structure of the coil panel assembly 100, etc., but is not limited thereto.

[0053] Referring to Figure 4, in some embodiments of the coil panel sheet 10 of the present application, the two coil braces 11 are defined as a first coil brace 111 and a second coil brace 113, respectively, the winding surfaces of the first coil brace and the second coil brace are arranged opposite each other and both have protruding winding portions, the winding portion 13 provided on the first coil brace 111 is a first winding portion 131, the winding portion 13 provided on the second coil brace 113 is a second winding portion 133, and the first winding portion 131 and the second winding portion 133 are arranged opposite each other.

[0054] In one embodiment of the present application, the two coil braces 11 arranged opposite each other in the coil panel sheet 10 are a first coil brace 111 and a second coil brace 113, respectively, and the winding surfaces of the first coil brace 111 and the second coil brace 113 are arranged opposite each other. In such a configuration, coils are wound around the first coil brace 111 and the second coil brace 113, and then these are stacked and combined, and then the coils in the first coil brace 111 and the second coil brace 113 are interposed between the first coil brace 111 and the second coil brace 113, thereby improving the structural stability of the coil 30, preventing the coil 30 from collapsing, and also avoiding an increased risk of the coil 30 being exposed to the outside and becoming worn, thereby improving the protective effect for the coil 30. Furthermore, a first winding portion 131 is protruded from the winding surface of the first coil brace 111, and a second winding portion 133 is protruded from the winding surface of the second coil brace 113. With this configuration, winding onto the first coil brace 111 and the second coil brace 113 becomes easier, improving the manufacturing efficiency of the coil panel assembly 100.

[0055] Referring to Figures 3 and 4, in some embodiments of the coil panel sheet 10 of the present application, the first coil brace 111 further includes a partition portion 15, which extends outward from the first winding portion 131 along the radial direction of the first coil brace 111, and the partition portion 15 is spaced apart from the winding surface of the first coil brace 111 to form a first winding gap 111b, and is spaced apart from the winding surface of the second coil brace 113 to form a winding gap.

[0056] As can be understood, in the coil panel sheet 10 of the present application, the at least two layers of wound coils 30 are all arranged between the two coil braces 11 of the coil panel sheet 10. In this case, if the spacing between the two layers of coils 30 is too small, mutual interference will occur during the winding process of the coils 30, and the heat dissipation efficiency of the coils 30 will also be affected. In one embodiment of the present application, a partition portion 15 extends outward along the radial direction of the first coil brace 111 on the side wall of the first winding portion 131. The partition portion 15 is arranged at a distance from the winding surface of the first coil brace 111 and the winding surface of the second coil brace 113, respectively, to form a first winding gap 111b and a second winding gap 113b. With this configuration, when winding the coils 30 around the two winding surfaces of the coil panel sheet 10, the partition portion 15 separates the coils 30 on both sides, thereby preventing the coils 30 on both sides from affecting each other during the winding process. Furthermore, by providing the partition portion 15, the coils 30 on both sides are spaced apart to form a heat dissipation gap, thereby ensuring that the heat dissipation efficiency of the coil panel assembly 100 is improved.

[0057] Furthermore, by providing the partition 15, the coils 30 on both sides of the partition 15 can be held down, preventing the coils 30 from collapsing or coming apart, thereby improving the structural stability of the coil panel assembly 100.

[0058] Referring to Figure 4, in some embodiments of the coil panel sheet 10 of the present application, the width of the partition portion 15 gradually increases toward the radial outside of the first coil brace 111, the central angle of the partition portion 15 is 180° or less, and the outer edge of the partition portion 15 does not extend beyond the edge of the first coil brace 111.

[0059] As can be understood, once the winding of the coil 30 is complete, the diameter of the coil 30 gradually increases with increasing distance from the winding portion 13. In one embodiment of the present application, the width of the partitions 15 gradually increases from the first winding portion 131 outward, thereby ensuring that the coil 30 is securely held in place by the partitions 15 at all radial positions, improving structural stability and preventing the coil 30 from being securely fixed due to the relatively small width of the partitions 15 at positions where a coil 30 with a large diameter is present. Furthermore, because the coil 30 is wound only on the winding surface, the outer edge of the partitions 15 does not extend beyond the outer edge of the first coil brace 111, preventing the coil panel assembly 100 from being too large in size. In addition, since the central angle of the partition 15 is less than 180°, a heat dissipation gap for the coil 30 is formed on one side of the partition 15, which prevents the placement of the partition 15 from affecting the heat dissipation of the coil 30, improves the heat dissipation efficiency of the coil panel assembly 100, reduces the risk of the coil panel assembly 100 being damaged by heating, and ensures the service life of the coil panel 100.

[0060] Here, the range of the width of the partition portion 15 may be determined depending on the size of the coil panel sheet 10 and the size of the heat dissipation gap, but is not limited thereto.

[0061] Referring to Figure 4, in some embodiments of the coil panel sheet 10 of the present application, the first winding portion 131 is provided in the center of the first coil brace 111, and multiple partition portions 15 are provided, and the multiple partition portions 15 are located at the same height on the first winding portion 131 and are arranged at intervals along the circumferential direction of the first coil brace 111.

[0062] In one embodiment of the present application, the first coil brace 111 is provided with a plurality of partitions 15 spaced apart along the circumferential direction, and the plurality of partitions 15 are arranged in a petal-like configuration at the same height on the first winding portion 131. This configuration enhances the fixing effect of the partitions 15 on the coil 30 and can equalize the pressure that the coil 30 receives at various positions in the circumferential direction. Meanwhile, the partitions 15 spaced apart form a heat dissipation gap between two adjacent partitions 15, thereby avoiding any effect on the heat dissipation of the coil 30 and improving the heat dissipation efficiency of the coil panel assembly 100.

[0063] Referring to Figure 4, in some embodiments of the coil panel sheet 10 of the present application, the first coil brace 111 is provided with multiple first heat dissipation holes 111a, and each of the first heat dissipation holes 111a is arranged opposite one of the partition portions 15.

[0064] As can be understood, in the coil panel sheet 10 of the present application, at least two layers of coils 30 are wound between two coil braces 11, and in such an arrangement, the coils 30 can only dissipate heat through the heat dissipation gap between the two coil braces 11, which affects heat dissipation efficiency. In one embodiment of the present application, the first coil brace 111 is provided with a plurality of first heat dissipation holes 111a, which penetrate two surfaces of the first coil brace 111. In such a configuration, the first heat dissipation holes 111a can be used to dissipate heat from the coils 30 between the two coil braces 11, improving heat dissipation efficiency.

[0065] Furthermore, by arranging each first heat dissipation hole 111a opposite one partition 15, it can be understood that two adjacent first heat dissipation holes 111a are separated by a connecting rib, and in this case, the multiple connecting ribs and multiple partitions 15 are provided at offset positions in the circumferential direction of the first coil brace 111, i.e., the coil 30 can be sandwiched between the partitions 15 and the first coil brace 111 at offset positions, thereby improving the structural stability of the coil 30. Furthermore, each portion of the coil 30 between the partitions 15 and the first coil brace 111 can dissipate heat through the heat dissipation gaps and first heat dissipation holes 111a on one side of the partitions 15, respectively, thereby improving the heat dissipation efficiency of the coil 30.

[0066] Referring to Figure 2, in some embodiments of the coil panel sheet 10 of the present application, the second coil brace 113 is provided with a plurality of second heat dissipation holes 113a, which are provided on the outer periphery of the second winding portion 133 and spaced apart along the circumferential direction of the second coil brace 113, and two adjacent second heat dissipation holes 113a are separated by a separating rib 113c.

[0067] Similarly, the second coil brace 113 is provided with a plurality of second heat dissipation holes 113a, which penetrate two surfaces of the second coil brace 113. In such a configuration, the second heat dissipation holes 113a can be used to dissipate heat from the coil 30 between the two coil braces 11, thereby improving heat dissipation efficiency.

[0068] Referring to Figure 2, in some embodiments of the coil panel sheet 10 of the present application, the first coil brace 111 further includes a plurality of partition portions 15, which are arranged at intervals along the circumferential direction of the first coil brace 111, and which extend outward from the first winding portion 131 along the radial direction of the first coil brace 111, and the plurality of separating ribs 113c and the plurality of partition portions 15 are arranged at staggered positions in the circumferential direction of the coil panel sheet 10.

[0069] Furthermore, in some embodiments, the first coil brace 111 is provided with multiple partitions 15, and in this case, the multiple partitions 15 and the multiple separating ribs 113c are arranged at circumferentially offset positions, i.e., the coil 30 can be sandwiched alternately between the partitions 15 and the second coil brace 113, thereby improving the structural stability of the coil 30. Also, each portion of the coil 30 between the partitions 15 and the second coil brace 113 can dissipate heat through the heat dissipation gap and the second heat dissipation hole 113a on one side of the partitions 15, respectively, thereby improving the heat dissipation efficiency of the coil 30 and also making it easier to fix the two coil braces 11 arranged opposite each other.

[0070] Referring to FIG. 2, in some embodiments of the coil panel sheet 10 of the present application, a pressure-bonding protrusion 113d is provided on the side of each separating rib 113c opposite to the first coil brace 111.

[0071] As can be understood, the coil panel sheet 10 proposed in the present application is used to wind a coil 30 to form a coil panel assembly 100, which is applied to a cookware. In one embodiment of the present application, a pressure protrusion 113d is provided on the surface of each separating rib 113c that faces away from the first coil brace 111, so that when the coil panel assembly 100 is attached to the cookware, components of the cookware, such as a heat retaining plate, can be pressed by the pressure protrusion 113d, thereby improving the stability of the entire cookware structure.

[0072] Referring to Figure 4, in some embodiments of the coil panel sheet 10 of the present application, the first coil brace 111 is provided with a first mounting hole 111c, the second coil brace 113 is provided with a second mounting hole 113f, the second mounting hole 113f and the first mounting hole 111c are arranged opposite each other, and the coil panel further includes a locking member 17, which is inserted into the first mounting hole 111c and the second mounting hole 113f to connect the first coil brace 111 and the second coil brace 113.

[0073] In one embodiment of the present application, one of the first mounting hole 111c and the second mounting hole 113f is a threaded hole, and the locking member 17 is a bolt, thereby connecting the first coil brace 111 and the second coil brace 113 with the bolt, simplifying the structure and making attachment and detachment easier. Both the first mounting hole 111c and the second mounting hole 113f may be through holes, and the first coil brace 111 and the second coil brace 113 may be connected using a matching structure of a bolt and a nut, but this is not particularly limited here.

[0074] Referring to Figures 3 and 4, in some embodiments of the coil panel sheet 10 of the present application, the second winding portion 133 is provided with an insertion hole 133a, and a portion of the first winding portion 131 is inserted into the insertion hole 133a.

[0075] In one embodiment of the present application, the second winding portion 133 is provided with an insertion hole 133a, and a portion of the first winding portion 131 is inserted into the insertion hole 133a. In this case, the coil 30 of the second coil brace 113 is wound around the second winding portion 133, and the coil 30 of the first coil brace 111 is wound around the first winding portion 131 that is not inserted into the insertion hole 133a. The matching of the first winding portion 131 and the insertion hole 133a improves the stability of the relative positions of the first coil brace 111 and the second coil brace 113 in the horizontal direction of the winding surface, and further improves the structural stability of the coil panel sheet 10.

[0076] Referring to Figures 3 and 4, in some embodiments of the coil panel sheet 10 of the present application, the first winding portion 131 includes a winding section 131a and an insertion section 131b connected to each other, the winding section 131a is protruding from the surface of the first winding brace, the insertion section 131b is protruding from the surface of the winding section 131a facing the second coil brace 113 and is inserted into the insertion hole 133a, and the end face of the winding section 131a abuts the end face of the second winding portion 133.

[0077] As can be understood, the first winding portion 131 and the second winding portion 133 are inserted and matched to improve the structural stability of the coil panel assembly 100. In one embodiment of the present application, a winding section 131a is provided protruding from the winding surface of the first winding portion 131, and an insertion section 131b is provided protruding from the end of the winding section 131a that is away from the winding surface, and the winding section 131a and the insertion section 131b are connected to form the first winding portion 131, which has a step-like structure. In this configuration, when the first winding portion 131 is inserted into the insertion hole 133a of the second winding portion 133, the insertion portion is inserted into the insertion hole 133a, while the winding portion 13 of the first winding portion 131 abuts against the end face of the insertion hole 133a, thereby limiting the insertion depth of the first winding portion 131 into the insertion hole 133a and limiting the distance between the two winding surfaces, thereby avoiding the two coil braces 11 being too close to each other and affecting the synchronization of the winding, and improving the structural stability of the coil panel sheet 10 and the manufacturing efficiency of the coil panel assembly 100.

[0078] In some embodiments of the coil panel sheet 10 of the present application, the distance d between the two winding surfaces satisfies 0.8 mm≦d≦2 mm.

[0079] As can be understood, the gap between the two coil braces 11 of the coil panel sheet 10 of the present application must be sufficient to allow at least two layers of coil 30 to be wound and to wind them simultaneously. If the winding gap of the coil panel sheet 10 is less than 0.8 mm, winding becomes difficult, and the two layers of coil 30 are likely to interfere with each other during winding. Alternatively, the distance between the two layers of coil 30 is too small to allow for timely heat dissipation, resulting in heat accumulation in the coil panel assembly 100 and affecting safety and stability of characteristics. However, if the gap between the two coil braces 11 is too large, the size of the cookware will be too large when applied to a cookware, making it difficult to use.

[0080] In one embodiment of the present application, the distance between the two winding surfaces is set to 0.8 mm or more to ensure that the width between the two coil braces 11 is sufficient for winding and to prevent mutual interference during the winding process. If the distance between the two winding surfaces exceeds 2 mm, the cookware would become too large and difficult to use when applied to the cookware. The distance between the two coil braces 11 may be set to 0.8 mm, 1.0 mm, 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm, 2.0 mm, or any value between 0.8 and 2 mm, depending on the number of layers of the coil 30 that need to be wound and the operating distance required for winding, but is not limited thereto.

[0081] Referring to Figure 4, in some embodiments of the coil panel sheet 10 of the present application, the coil panel sheet 10 is provided with a brace hole 16, which passes through the two coil braces 11 and the winding portion 13.

[0082] In one embodiment of the present application, brace holes 16 that penetrate two coil braces 11 and the winding portion 13 are provided in the coil panel sheet 10, thereby generating air convection on both sides of the coil panel sheet, thereby improving the heat dissipation efficiency of the coil panel assembly 100.

[0083] It is also understandable that the coil panel sheet 10 proposed in the present application is primarily used to wind the coil 30 to form the coil panel assembly 100, and is applied to a cooking appliance. In some embodiments, the cooking appliance is also provided with components such as a temperature control member for detecting the temperature inside the cooking chamber. In this case, by arranging the components such as the temperature control member in the brace hole 16, the space can be fully utilized, the space utilization rate can be increased, the overall structure of the cooking appliance can be made more compact, and the volume of the cooking appliance can be reduced.

[0084] Referring to Figures 2 and 5, in some embodiments of the coil panel sheet 10 of the present application, the coil panel sheet 10 further includes a wire stop clip 18, which is provided on an edge of one of the coil braces 11, and which has at least two wire stop grooves 181.

[0085] As can be understood, the coil panel sheet 10 of the present application is used to wind the coils 30, and in order to facilitate connection to an external power source, the lead wires at both ends of the coils 30 need to extend to the outside of the coil panel sheet 10. In one embodiment of the present application, a wire fastening clip 18 is provided on the edge of the coil panel sheet 10, but the wire fastening clip 18 may also be provided on any of the coil braces 11, and may be integrally formed with the coil brace 11 or may be removably connected. The wire fastening clip 18 is provided with at least two wire fastening grooves 181, and when at least two layers of coils 30 of the coil panel assembly 100 are connected in series with each other, the lead wires of only two coils 30 in the coil panel assembly 100 can be fastened to the two wire fastening grooves 181, respectively. When at least two layers of coils 30 of the coil panel assembly 100 are connected in parallel to each other, each layer of coils 30 has two coil 30 lead wires, and in this case, the number of wire fastening grooves 181 may correspond to the number of coil 30 lead wires, or each wire fastening groove 181 may be used to fasten two or more lead wires, but this is not limited thereto. By providing the wire fastening clips 18, both ends of the coil 30 wound inside the coil panel sheet 10 are fixed, maintaining the structural stability of the wound coil 30 and preventing the coil 30 from collapsing or being disassembled.

[0086] Referring to FIG. 2, in some embodiments of the coil panel sheet 10 of the present application, an extension portion 19 for fixing the coil panel sheet 10 is protruded from the peripheral edge of one of the coil braces 11.

[0087] In one embodiment of the present application, an extension portion 19 is provided protruding from the periphery of one of the coil braces 11 in the coil panel sheet 10, and a plurality of extension portions 19 may be provided, spaced apart along the circumferential direction of the coil brace 11. The extension portion 19 is provided to lock the extension portion 19 to secure the coil panel assembly 100 when the coil panel assembly 100 is attached inside the cookware. Here, the extension portion 19 has a clip structure, but it may also have a structure such as a connection hole through which a connecting member such as a bolt can be inserted, and this is not limited thereto.

[0088] Referring to FIG. 2, in some embodiments of the coil panel sheet 10 of the present application, one of the coil braces 11 is provided with a connection hole 191 through which a connecting member passes to fix the coil panel sheet 10.

[0089] In one embodiment of the present application, a connection hole 191 is provided on one side of the coil brace 11 in the coil panel sheet 10, and a plurality of connection holes 191 may be provided, spaced apart along the circumferential direction of the coil brace 11. The connection holes 191 are provided so that when the coil panel assembly 100 is attached inside the cooking appliance, a connection member is inserted into the connection hole 191 to connect to the internal structure of the cooking appliance, thereby fixing the coil panel assembly 100.

[0090] In some embodiments, the coil brace 11 has an extension 19 formed on its periphery, and in this case, the connection hole 191 may be provided in the extension 19. As can be understood, since the extension 19 is a connection structure, the coil 30 is not wound onto the extension 19 when being wound. Therefore, providing the connection hole 191 in the extension 19 prevents the coil 30 from interfering with the attachment and detachment of the connection member, thereby improving the convenience of attachment and detachment of the coil panel assembly 100.

[0091] With reference to Figures 1 to 4, the present application also proposes a coil panel assembly 100 including at least two layers of coils 30 and any of the coil panel sheets 10 described above, wherein the at least two layers of coils 30 are wound around two coil braces 11 of the coil panel sheet 10, and at least one layer of coils 30 is provided on the winding surface of each of the coil braces 11.

[0092] The coil panel assembly 100 proposed in the present application includes a coil panel sheet 10 and at least two layers of coils 30 wound around the coil panel sheet 10. Specifically, the coil panel sheet 10 is provided with two coil braces 11 arranged opposite to each other, and the at least two coil braces 11 are arranged opposite to each other and removably connected. As can be understood, the first coil brace 111 and the second coil brace 113 are detachable so as to be separated from each other. In this case, when winding the coil 30, the two coil braces 11 can be disassembled, the coil 30 can be wound around each of the two coil braces 11, and then stacked and combined. This improves the winding efficiency of the coil 30 and the manufacturing efficiency of the coil panel assembly 100 compared to a manufacturing method in which the coil 30 is wound layer by layer. If it is necessary to disassemble the entire coil panel assembly 100, the two coil braces 11 can be directly separated to efficiently remove the coil 30, thereby improving the ease of disassembly of the coil panel assembly 100.

[0093] In one embodiment of the present application, the means for detachably connecting the two coil braces 11 may be, but is not limited to, a clip connection, a bolt connection, a screw connection, or an adhesive connection. The outline of the coil brace 11 may be circular, semicircular, rectangular, or another polygonal shape, and may be set depending on the number of turns and size of the coil 30 to be wound, the structure of the coil panel assembly 100 at the installation position, and the like.

[0094] Therefore, as can be understood, in the technical solution of the present application, the coil panel sheet 10 is configured by combining at least two coil braces 11, and the two coil braces 11 arranged opposite each other are removably connected, so that in this configuration, when winding the coil 30, the two coil braces 11 can be disassembled, and the coil 30 can be wound around each of the two coil braces 11, and then these can be stacked and combined, eliminating the need to wind the coil 30 layer by layer as in conventional structures, thereby improving the manufacturing efficiency of the coil panel assembly 100.

[0095] The coil panel assembly 100 proposed in the present application is applicable to all the technical solutions of all the above-mentioned embodiments, and therefore has at least all the beneficial effects of all the above-mentioned technical solutions, so it will not be described in detail here.

[0096] The present application also proposes a lid assembly, which includes a lid and the coil panel assembly 100, wherein a storage chamber is formed within the lid, and the coil panel assembly 100 is provided in the storage chamber.

[0097] The lid assembly proposed in this application is applied to a cooking utensil and is used to seal the cooking chamber of the cooking utensil to create a relatively sealed cooking environment in the cooking chamber, preventing food from spilling in the cooking chamber, and in the case of a cooking utensil such as a pressure cooker, improving the cooking effect of the food and shortening the cooking time. Specifically, a cooking utensil generally includes a utensil body, which is provided with a cooking chamber for accommodating food, and a lid of the lid assembly is attached to the utensil body to close the opening of the cooking chamber and form a relatively sealed cooking chamber.

[0098] In some embodiments, the lid includes an outer lid and an inner lid that are joined together. The outer lid generally includes a top plate and a side plate, which define a storage space. The inner lid is attached to the opening of the storage space to form a storage chamber. The coil panel assembly 100 is then installed in the storage space as a whole. The movable lid plate is installed outside the storage space. When the lid assembly is applied to a cooking appliance, it is directly installed in the cooking chamber of the appliance body. In this case, the coil panel assembly 100 is heated directly through the movable lid plate, thereby heating the food in the cooking chamber and improving heat transfer efficiency. Furthermore, the coil panel assembly 100 used in the present application has at least two layers of coils 30. This configuration improves the power of the coil panel assembly 100 and increases the strength of the AC magnetic field generated when it is activated, thereby improving heating efficiency and speeding up cooking.

[0099] In the coil panel assembly 100 employed in the present application, the coil panel sheet 10 is configured by combining at least two coil braces 11, and the two coil braces 11 arranged opposite each other are removably connected. With this configuration, when winding the coil 30, the two coil braces 11 can be disassembled, and the coil 30 can be wound around each of the two coil braces 11, and then these can be stacked and combined. This eliminates the need to wind the coil 30 layer by layer as in conventional structures, thereby improving the manufacturing efficiency of the coil panel assembly 100.

[0100] The lid assembly proposed in this application is applicable to all the technical solutions of all the above-mentioned embodiments, and therefore has at least all the beneficial effects of all the above-mentioned technical solutions, so it will not be described in detail here.

[0101] The present application also proposes a cooking utensil, which includes an utensil body and the lid assembly, and the lid assembly is attached to the utensil body.

[0102] The cooking appliance includes a main body and any of the above-described lid assemblies, with the lid assembly attached to the main body. The cooking appliance may be an electric pressure cooker, a rice cooker, or the like. Taking a rice cooker as an example, the rice cooker generally includes a main body and a lid assembly, with a cooking chamber for containing food inside the main body. The lid assembly includes a lid, which is attached to the main body and closes the opening of the cooking chamber, forming a relatively sealed cooking chamber. The lid assembly further includes a coil panel assembly 100 and a magnetic insulating sheet. In this configuration, the coil panel assembly 100 directly heats the movable lid plate of the lid assembly, allowing the cooking chamber to be heated quickly and improving heat transfer efficiency. Furthermore, the coil panel assembly 100 applied in the present application is provided with at least two layers of coils 30, and in such a configuration, the power of the coil panel assembly 100 is improved, and the strength of the alternating magnetic field generated when it is operated is increased, thereby improving heating efficiency and increasing cooking speed.

[0103] In the coil panel assembly 100 employed in the present application, the coil panel sheet 10 is configured by combining at least two coil braces 11, and the two coil braces 11 arranged opposite each other are removably connected. With this configuration, when winding the coil 30, the two coil braces 11 can be disassembled, and the coil 30 can be wound around each of the two coil braces 11, and then these can be stacked and combined. This eliminates the need to wind the coil 30 layer by layer as in conventional structures, thereby improving the manufacturing efficiency of the coil panel assembly 100.
