The present application proposes a coil disc seat 10 .

Please refer to FIG. 1 and FIG. 3 . In some embodiments of the coil disc base 10 of the present application, the coil disc base 10 includes at least two coil supports 11 disposed opposite to each other, and the two coil supports 11 disposed opposite to each other are detachably connected.

The coil disk seat 10 proposed in the present application is mainly used as a bearing base of the coil disk assembly 100 for winding the coil 30; the common coil disk assembly 100 is provided with a winding surface for supporting the coil 30 or is provided with a spiral winding groove. When the coil disk assembly 100 is provided with multiple layers of coils 30, the coils 30 need to be wound layer by layer on the coil surface or the winding groove. The coil disk seat 10 proposed in the present application is provided with at least two coil supports 11, and at least two coil supports 11 are arranged opposite to each other and detachably connected. It can be understood that the first coil support 111 and the second coil support 113 are detachable to be separated from each other. At this time, the two coil supports 11 can be disassembled when winding the coil 30, and the coil 30 is respectively wound on the two coil supports 11 and then stacked and combined. Compared with the manufacturing method of winding layer by layer, the winding efficiency of the coil 30 and the manufacturing efficiency of the coil disk assembly 100 are improved; when the overall coil disk assembly 100 needs to be disassembled, the two coil supports 11 can also be directly separated to quickly disassemble the coil 30, thereby improving the convenience of disassembly of the coil disk assembly 100.

It should be noted that, in one embodiment of the present application, the detachable connection between the two coil supports 11 can be a snap connection, a bolt connection, a threaded connection, an adhesive connection, etc., which is not specifically limited here. In addition, the profile of the coil support 11 can be a circular, semicircular, rectangular or other polygonal structure, which only needs to be set according to the number of turns and size of the coil 30 to be wound and the structure of the installation position of the coil disk assembly 100.

Therefore, it can be understood that the technical solution of the present application, by configuring the coil disk seat 10 to be a combination structure of at least two coil supports 11, and making the two relatively arranged coil supports 11 detachably connected, can be configured such that the two coil supports 11 can be disassembled when winding the coil 30, and the coils 30 can be wound on the two coil supports 11 respectively and then stacked and combined. There is no need to wind the coils 30 layer by layer as in the traditional structure, thereby improving the manufacturing efficiency of the coil disk assembly 100.

Please refer to FIG. 4 . In some embodiments of the coil disc base 10 of the present application, each of the coil supports 11 is provided with a winding surface, and at least one of the winding surfaces is provided with a winding portion 13 convexly.

In one embodiment of the present application, each coil bracket 11 is provided with a winding surface. The coil bracket 11 is roughly disc-shaped and has two surfaces arranged back to back. In this case, both surfaces can be winding surfaces, or one surface can be selected as the winding surface. For example, the surfaces of the two coil brackets 11 arranged opposite to each other or the surfaces arranged back to back can be used as winding surfaces, which is not limited here. The setting of the winding surface can be used to carry the coil 30, reduce the risk of the coil 30 spreading out, and improve the convenience of winding the coil 30.

Furthermore, a winding portion 13 may be convexly provided on the winding surface, and the winding portion 13 is generally provided in the middle of the coil support 11. In this case, the coil 30 may be positioned by the winding portion 13, and the coil may be wound with the winding portion 13 as the winding basis, thereby further improving the convenience of winding the coil 30. It should be noted that, in one embodiment of the present application, a winding portion 13 may be convexly provided on the winding surface of each coil support 11, or a winding portion 13 may be convexly provided on only one of the winding surfaces, and it only needs to be provided correspondingly based on the structure of the installation position, the structure of the coil disk assembly 100, etc., and is not limited here.

Referring to FIG. 4 , in some embodiments of the coil disc seat 10 of the present application, the two coil supports 11 are defined as a first coil support 111 and a second coil support 113 , the winding surfaces of the first coil support and the second coil support are arranged opposite to each other, and both of them are provided with a convex winding portion;

The winding portion 13 provided on the first coil support 111 is a first winding portion 131 , and the winding portion 13 provided on the second coil support 113 is a second winding portion 133 . The first winding portion 131 and the second winding portion 133 are arranged opposite to each other.

In one embodiment of the present application, the two coil supports 11 relatively arranged in the coil disk seat 10 are respectively the first coil support 111 and the second coil support 113, and the winding surfaces of the first coil support 111 and the second coil support 113 are relatively arranged. In this arrangement, after the first coil support 111 and the second coil support 113 are wound and stacked, the coils on the first coil support 111 and the second coil support 113 are clamped between the first coil support 111 and the second coil support 113, thereby improving the structural stability of the coil 30, avoiding the scattering of the coil 30, and avoiding the increased risk of wear caused by the exposure of the coil 30, thereby improving the protection of the coil 30; further, the winding surface of the first coil support 111 is convexly provided with a first winding portion 131, and the winding surface of the second coil support 113 is convexly provided with a second winding portion 133. In this arrangement, the convenience of winding on the first coil support 111 and the second coil support 113 can be improved, and the manufacturing efficiency of the coil disk assembly 100 can be improved.

Please refer to Figures 3 and 4. In some embodiments of the coil disk base 10 of the present application, the first coil support 111 also includes a partition 15, and the partition 15 extends radially outward from the first winding portion 131 along the first coil support 111. The partition 15 is spaced apart from the winding surface of the first coil support 111 to form a first winding gap 111b, and is spaced apart from the winding surface of the second coil support 113 to form a winding gap.

It can be understood that at least two layers of coils 30 wound in the coil disc seat 10 of the present application are arranged between the two coil supports 11 of the coil disc seat 10. At this time, if the spacing between the two layers of coils 30 is too small, it is easy to cause mutual interference during the winding process of the coils 30, which will also affect the heat dissipation efficiency of the coils 30. In one embodiment of the present application, the side wall of the first winding portion 131 extends radially outward along the first coil support 111 to form a partition 15, and the partition 15 is spaced apart from the winding surface of the first coil support 111 and the winding surface of the second coil support 113 to form a first winding gap 111b and a second winding gap 113b. In this way, when the coils 30 are wound on the two winding surfaces of the coil disc seat 10, the coils 30 on both sides can be separated by the partition 15 to avoid mutual influence between the winding processes of the coils 30 on both sides; in addition, the setting of the partition 15 can ensure that the coils 30 on both sides are spaced apart to form a heat dissipation gap, thereby improving the heat dissipation efficiency of the coil disc assembly 100.

In addition, the partition 15 can also be used to press the coils 30 on both sides of the partition 15 to prevent the coils 30 from being scattered and decomposed, thereby improving the structural stability of the coil disk assembly 100.

Please refer to Figure 4. In some embodiments of the coil disk base 10 of the present application, the width of the partition 15 gradually increases radially outwardly along the first coil support 111, the central angle of the partition 15 does not exceed 180°, and the outer edge of the partition 15 does not exceed the edge of the first coil support 111.

It can be understood that after the coil 30 is wound, the diameter of the coil 30 gradually increases in the direction away from the winding part 13. In one embodiment of the present application, the width of the partition 15 is gradually increased from the first winding part 131 to the outside, so as to ensure that each position of the coil 30 along the radial direction can be well pressed by the partition 15, improve the structural stability, and avoid the position of the coil 30 with a larger diameter and the partition 15 width is small and the coil 30 cannot be well fixed; and because the coil 30 is only wound on the winding surface, the outer edge of the partition 15 does not exceed the outer edge of the first coil support 111, which can avoid the size of the coil disk assembly 100 being too large. In addition, the center angle of the partition 15 is less than 180°, so as to form a heat dissipation gap for the heat dissipation of the coil 30 on one side of the partition 15, so as to avoid the setting of the partition 15 affecting the heat dissipation of the coil 30, so as to improve the heat dissipation efficiency of the coil disk assembly 100, reduce the risk of damage caused by overheating of the coil disk assembly 100, and ensure the service life of the coil disk 100.

The width range of the partition 15 can be selected according to the size of the coil disc seat 10 and the heat dissipation gap, and is not limited here.

Please refer to Figure 4, in some embodiments of the coil disk base 10 of the present application, the first winding portion 131 is disposed in the middle of the first coil support 111, and a plurality of the partitions 15 are provided. The plurality of partitions 15 are located at the same height position of the first winding portion 131 and are arranged at intervals along the circumference of the first coil support 111.

In one embodiment of the present application, a plurality of partitions 15 spaced apart along the circumferential direction are provided on the first coil support 111. The plurality of partitions 15 are arranged at the same height position of the first winding portion 131 to form a petal-like structure. Such a configuration can enhance the fixing effect of the partitions 15 on the coil 30, so that the pressure on the coil 30 at various circumferential positions is uniform. The spaced apart partitions 15 can form a heat dissipation gap between two adjacent partitions 15 to avoid affecting the heat dissipation of the coil 30 and enhance the heat dissipation efficiency of the coil disk assembly 100.

Referring to FIG. 4 , in some embodiments of the coil disc base 10 of the present application, the first coil support 111 defines a plurality of first heat dissipation holes 111 a , and each of the first heat dissipation holes 111 a is disposed opposite to one of the partitions 15 .

It is understandable that in the coil disc seat 10 of the present application, at least two layers of coils 30 are wound between two coil supports 11, but this arrangement will cause the coil 30 to only rely on the heat dissipation gap between the two coil supports 11 for heat dissipation, affecting the heat dissipation efficiency. In one embodiment of the present application, a plurality of first heat dissipation holes 111a are provided on the first coil support 111, and the first heat dissipation holes 111a penetrate the two surfaces of the first coil support 111. In this arrangement, the first heat dissipation holes 111a can be used to dissipate heat for the coil 30 between the two coil supports 11, thereby improving the heat dissipation efficiency.

In addition, each first heat dissipation hole 111a is arranged opposite to a partition 15. It can be understood that two adjacent first heat dissipation holes 111a are separated by connecting ribs. At this time, multiple connecting ribs and multiple partitions 15 are staggered along the circumference of the first coil support 111, that is, the coil 30 between the partition 15 and the first coil support 111 can be staggered to clamp each other, thereby improving the structural stability of the coil 30; and each section of the coil 30 between the partition 15 and the first coil support 111 can be cooled by the heat dissipation gap on one side of the partition 15 and the first heat dissipation hole 111a, respectively, thereby improving the heat dissipation efficiency of the coil 30.

Please refer to Figure 2. In some embodiments of the coil disk base 10 of the present application, the second coil support 113 is provided with a plurality of second heat dissipation holes 113a. The plurality of second heat dissipation holes 113a are arranged on the circumferential side of the second winding portion 133 and are spaced apart along the circumferential direction of the second coil support 113. Two adjacent second heat dissipation holes 113a are separated by isolation ribs 113c.

Similarly, a plurality of second heat dissipation holes 113a are provided on the second coil support 113, and the second heat dissipation holes 113a pass through two surfaces of the second coil support 113. With such an arrangement, the second heat dissipation holes 113a can be used to dissipate heat for the coil 30 between the two coil supports 11, thereby improving heat dissipation efficiency.

Referring to FIG. 2 , in some embodiments of the coil disc seat 10 of the present application, the first coil support 111 further includes a plurality of partitions 15 , the plurality of partitions 15 are arranged at intervals along the circumference of the first coil support 111 , and the partitions 15 extend radially outward from the first winding portion 131 along the first coil support 111 ;

The plurality of isolation ribs 113 c and the plurality of partitions 15 are staggeredly disposed along the circumferential direction of the coil disk base 10 .

Furthermore, in some embodiments, a plurality of partitions 15 are provided on the first coil support 111. In this case, the plurality of partitions 15 and the plurality of isolation ribs 113c are staggered in the circumferential direction, that is, the coil 30 between the partitions 15 and the second coil support 113 can be staggered to sandwich each other, thereby improving the structural stability of the coil 30; and each section of the coil 30 between the partitions 15 and the second coil support 113 can be cooled by the heat dissipation gap and the second heat dissipation hole 113a on one side of the partition 15, respectively, thereby improving the heat dissipation efficiency of the coil 30 and facilitating the fixation between the two relatively arranged coil supports 11.

Referring to FIG. 2 , in some embodiments of the coil disc base 10 of the present application, a crimping protrusion 113 d is protruded from a side of each of the isolation ribs 113 c that is away from the first coil support 111 .

It can be understood that the coil disc seat 10 proposed in the present application is mainly used to wind the coil 30 to form a coil disc assembly 100, and is applied to a cooking utensil. In one embodiment of the present application, by providing a crimping protrusion 113d on the surface of each isolation rib 113c away from the first coil support 111, when the coil disc assembly 100 is installed in the cooking utensil, the crimping protrusion 113d can be used to press components such as a heat preservation plate in the cooking utensil, thereby improving the stability of the overall structure of the cooking utensil.

Referring to FIG. 4 , in some embodiments of the coil disc seat 10 of the present application, the first coil support 111 is provided with a first mounting hole 111c, the second coil support 113 is provided with a second mounting hole 113f, and the second mounting hole 113f is arranged opposite to the first mounting hole 111c;

The coil disk further includes a locking member 17 , and the locking member 17 is passed through the first mounting hole 111 c and the second mounting hole 113 f to connect the first coil support 111 and the second coil support 113 .

In one embodiment of the present application, one of the first mounting hole 111c and the second mounting hole 113f can be a threaded hole, and the locking member 17 can be a bolt, and the first coil support 111 and the second coil support 113 can be connected by the bolt, which has a simple structure and is easy to disassemble and assemble. The first mounting hole 111c and the second mounting hole 113f can also be through holes, and the first coil support 111 and the second coil support 113 can be connected by the matching structure of the bolt and the nut, which is not specifically limited here.

Please refer to FIG. 3 and FIG. 4 , in some embodiments of the coil disc base 10 of the present application, the second winding portion 133 is provided with an inserting hole 133 a , and part of the first winding portion 131 is inserted into the inserting hole 133 a .

In one embodiment of the present application, a plug hole 133a is provided on the second winding portion 133, so that part of the first winding portion 131 is inserted into the plug hole 133a. At this time, the coil 30 on the second coil support 113 is wound on the second winding portion 133, and the coil 30 of the first coil support 111 is wound on the first winding portion 131 that is not inserted into the plug hole 133a. Through the plug-in cooperation between the first winding portion 131 and the plug hole 133a, the relative position stability of the first coil support 111 and the second coil support 113 in the horizontal direction of the winding surface can be improved, thereby improving the structural stability of the coil reel seat 10.

Referring to FIGS. 3 and 4 , in some embodiments of the coil disc base 10 of the present application, the first winding portion 131 includes a winding segment 131 a and a plug-in segment 131 b connected to each other;

The winding segment 131a is protruded from the surface of the first winding bracket, the plug-in segment 131b is protruded from the surface of the winding segment 131a facing the second coil bracket 113 and is inserted into the plug-in hole 133a, and the end face of the winding segment 131a abuts against the end face of the second winding portion 133.

It can be understood that the structural stability of the coil disk assembly 100 can be improved through the plug-in fit between the first winding portion 131 and the second winding portion 133 . In one embodiment of the present application, a winding segment 131a is protruded on the winding surface of the first winding portion 131, and an inserting segment 131b is protruded on the end of the winding segment 131a away from the winding surface. The winding segment 131a and the inserting segment 131b are connected to form the aforementioned first winding portion 131, and are similar to a step structure. In this way, when the first winding portion 131 is inserted into the inserting hole 133a of the second winding portion 133, the inserting portion is inserted into the inserting hole 133a, and the winding portion 13 of the first winding portion 131 abuts against the end surface of the inserting hole 133a to limit the depth of the first winding portion 131 inserted into the inserting hole 133a, thereby limiting the distance between the two winding surfaces, avoiding the two coil supports 11 from being too close to each other and affecting the synchronous winding, thereby improving the structural stability of the coil disk seat 10 and the manufacturing efficiency of the coil disk assembly 100.

In some embodiments of the coil disc base 10 of the present application, the distance d between the two winding surfaces satisfies 0.8 mm ≤ d ≤ 2 mm.

It is understandable that the gap between the two coil supports 11 of the coil disc seat 10 of the present application needs to be enough to wind at least two layers of coils 30, and it must be able to wind at the same time. If the winding gap of the coil disc seat 10 is less than 0.8mm, it will make it difficult to wind, and it is easy to cause the two layers of coils 30 to interfere with each other, or cause the two layers of coils 30 to be too close to each other and unable to dissipate heat in time, causing heat to accumulate on the coil disc assembly 100, affecting safety and performance stability. However, if the distance between the two coil supports 11 is too large, it is easy to cause the cooking utensil to be too large in size after it is applied to the cooking utensil, which is inconvenient to use.

In one embodiment of the present application, the distance between the two winding surfaces is not less than 0.8 mm, so as to ensure that there is enough width between the two coil supports 11 for winding and avoid mutual interference in the winding process; if the spacing between the two winding surfaces exceeds 2 mm, it is easy to cause the cooking utensil to be too large after it is applied to the cooking utensil, which is inconvenient to use. The distance between the two coil supports 11 can be 0.8 mm, 1.0 mm, 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm, 2.0 mm and any value between 0.8 and 2 mm. It only needs to be set according to the number of layers of coils 30 to be wound, or it can be set according to the operating distance that is convenient for winding. It is not limited here.

Please refer to FIG. 4 . In some embodiments of the coil disc base 10 of the present application, the coil disc base 10 is provided with a bracket hole 16 . The bracket hole 16 passes through the two coil brackets 11 and the winding portion 13 .

The wire fixing buckle 18 is arranged on the edge of one of the coil brackets 11. The wire fixing buckle 18 has at least two wire fixing grooves 181.

It can be understood that the coil disc base 10 of the present application is used to wind the coil 30, and the lead wires at both ends of the coil 30 need to extend to the outside of the coil disc base 10 to facilitate connection with an external power source. In one embodiment of the present application, a wire fixing buckle 18 is provided on the edge of the coil disc seat 10. The wire fixing buckle 18 can be provided on any coil support 11, and can be integrally formed with the coil support 11 or can be detachably connected; at least two wire fixing grooves 181 are provided on the wire fixing buckle 18. When at least two layers of coils 30 of the coil disc assembly 100 are connected in series with each other, the coil disc assembly 100 has only two coil 30 lead-out wires, and the two coil 30 lead-out wires can be respectively clamped in the two wire fixing grooves 181. When at least two layers of coils 30 in the coil disc assembly 100 are connected in parallel with each other, each layer of coil 30 has two coil 30 lead-out wires. At this time, a corresponding number of wire fixing grooves 181 can be provided according to the number of coil 30 lead-out wires, or each wire fixing groove 181 can be used to clamp two or more lead-out wires, which is not limited here. The provision of the wire fixing buckle 18 can fix the two ends of the coil 30 wound inside the coil disc seat 10, maintain the structural stability of the wound coil 30, and avoid the coil 30 from being scattered and decomposed.

Please refer to FIG. 2 . In some embodiments of the coil disc base 10 of the present application, one of the coil brackets 11 is provided with a connecting hole 191 for passing a connecting piece to fix the coil disc base 10 .

In one embodiment of the present application, a connecting hole 191 is provided in one of the coil supports 11 in the coil disk seat 10. A plurality of connecting holes 191 may be provided and are arranged at circumferential intervals along the coil support 11. The setting of the connecting holes 191 is intended to enable the connecting piece to pass through the connecting hole 191 and be connected to the internal structure of the cooking utensil to fix the coil disk assembly 100 when the coil disk assembly 100 is installed inside the cooking utensil.

In some embodiments, an extension portion 19 is protruding from the periphery of the coil support 11. In this case, the connecting hole 191 can be opened on the extension portion 19. It can be understood that the extension portion 19 serves as a connecting structure, and when the coil 30 is wound, the coil 30 will not be wound around the extension portion 19. In this case, opening the connecting hole 191 on the extension portion 19 can avoid the coil 30 interfering with the disassembly and assembly of the connector, thereby improving the convenience of disassembly and assembly of the coil disk assembly 100.
