[0050] The coil windings of existing coil disks usually have regular shapes such as round, square, rectangular, and elliptical. The shape of the coil winding corresponds to the heated area. If a larger heating area is desired, the overall size of the coil winding needs to be increased. However, if a cookware with a small bottom area is used, the coil area that can be covered is small, especially since the outer ring of the coil winding is too far away from the cookware, the electrical control signal will become poor, the power will be low, the performance will be reduced, it will be easily damaged, and the reliability will be reduced.
[0051] In order to solve the above problems, the utility model provides a coil disk. Figure 1 A schematic plan view of a first embodiment of a coil disk assembly provided by the utility model; Figure 2 for Figure 1 Schematic diagram of the A-A section; Figure 3 for Figure 1 Schematic diagram of the B-B section; Figure 4 A schematic plan view of a second embodiment of a coil disk assembly provided by the utility model; Figure 5 for Figure 4 Schematic diagram of the A-A section; Figure 6 for Figure 4 Schematic diagram of the B-B section;
[0052] Figure 7 A schematic plan view of a third embodiment of a coil disk assembly provided by the utility model; Figure 8 for Figure 7 Schematic diagram of the A-A section; Fig. 9 for Figure 7 Schematic diagram of the B-B section; Fig.10 A schematic plan view of a fourth embodiment of a coil disk assembly provided by the utility model; Fig.11 for Fig.10 Schematic diagram of the A-A section; Fig.12 for Fig.10 Schematic diagram of the B-B section.
[0053] See also Figures 1 to 3 The coil disk includes a mounting bracket 1 and a first coil winding 2, the mounting bracket 1 has a corner portion 10; the first coil winding 2 is wound on the mounting bracket 1, and the first coil winding 2 has a convex portion 20 extending to the corner portion 10 and protruding relative to the adjacent winding, and the angle formed between the convex portion 20 and the adjacent winding is set to be greater than the angle formed by the extension directions of the two windings adjacent to the convex portion 20.
[0054] It should be noted that the corner portion 10 can be understood as a non-arc shape, so the coil disk is a non-circular shape, that is, the coil disk is set to be a special-shaped coil disk with a corner portion 10, such as a polygon, fan-shaped, etc., which can be flexibly set according to actual needs.
[0055] It should also be noted that, in order to enable the coil winding to have a more concentrated heating area, the two adjacent turns of the coil are generally arranged in sequence at regular and equal intervals. In order to fit the bottom of the pot, the coil winding is generally set in a circular shape, and the first coil winding 2 has the protrusion 20, which is adapted to the corner portion 10. When the pot is placed on one side of the coil disk assembly 100, it is fully coupled with the bottom of the larger pot.
[0056] It can be understood that, because the first coil winding 2 has the protrusion 20, the main part of the first coil winding 2 does not need to be set too large. The overall outer dimensions of the first coil winding 2 are relatively large and can be coupled with large-sized cookware. Then, relatively speaking, the main part of the first coil winding 2 can be reduced accordingly. When coupled with a smaller cookware, the main part of the first coil winding 2 can also participate in the coupling. Therefore, when the cookware is slightly smaller, it has no effect on the performance of the coil disk assembly 100.
[0057] In the technical solution provided by the utility model, the coil disk assembly 100 includes a mounting bracket 1 and a first coil winding 2, the mounting bracket 1 has a corner portion 10, the first coil winding 2 is wound on the mounting bracket 1, the first coil winding 2 has a convex portion 20 extending to the corner portion 10, the angle formed between the convex portion 20 and the winding adjacent to it is greater than the angle formed by the extension directions of the two windings adjacent to the convex portion 20, the two windings adjacent to the convex portion 20 are transitioned through the convex portion 20, the current direction of the wire is avoided to change suddenly, the degree of cancellation of the magnetic field component is reduced, and the sudden change of the electromagnetic field is alleviated, and the convex portion 20 extends to the corner portion 10, and can cover the mounting bracket 1 as much as possible, when the mounting bracket 1 is set to be square, the corner portions 10 formed at the four corners of the mounting bracket 1 can correspond to the convex portion 20, so as to facilitate coupling heating with square cookware, so as to solve the problem that the existing square coil disk has a heating blind spot at the corner of the square cookware.
[0058] It should also be noted that, because the protrusion 20 is adapted to the corner portion 10 of the mounting bracket 1, the first coil winding 2 can produce an enlarged working area. When the size of the cookware is large, there is no need to increase the size of the entire coil disk assembly 100, and the cookware can also couple with the first coil winding 2. When the size of the cookware is small, the cookware is coupled with the non-protruding part of the first coil winding 2, and the number of coil turns participating in the coupling of the cookware is equivalent, thereby ensuring the performance of the coil disk assembly 100, so that the coil disk assembly 100 can provide a larger heating area and the performance will not be reduced when using a small-bottom cookware.
[0059] Specifically, in one embodiment, the mounting bracket 1 is arranged in a square shape to have a plurality of side edges, and the corner portions 10 are formed at the intersection of the adjacent two side edges. Thus, when the main body of the first coil winding 2 is circular, the four corners of the mounting bracket 1 respectively form the convex portions 20 relative to the first coil winding 2. Of course, the mounting bracket 1 may also be arranged in other possible shapes, such as a pentagon, a hexagon, a rhombus, etc., which may be determined according to actual conditions, and the embodiments of this specification do not limit this.
[0060] Specifically, in this embodiment, the mounting bracket 1 has a plurality of corner portions 10, and correspondingly, the first coil winding 2 has a plurality of protrusions 20. In this way, the first coil winding 2 is adapted to each of the corner portions 10 of the mounting bracket 1, so that the first coil winding 2 can provide a larger outer size and can be coupled with a larger size of cookware.
[0061] It can be understood that the protrusions 20 can be set to coil segments with the same shape and the same winding method, or can be set to coil segments with different shapes and winding methods, which can be determined according to actual conditions.
[0062] In this embodiment, the first coil winding 2 has a plurality of protrusions 20 spaced apart along the circumference, each of the protrusions 20 being formed by a portion of the first coil winding 2 protruding outward relative to an adjacent portion, and a recess of the first coil winding 2 is formed between two adjacent protrusions 20 .
[0063] In this way, when the size of the cookware is larger, the cookware can be coupled with multiple said protrusions 20 and multiple said recesses, and the performance of the coil disk assembly 100 can be fully exerted. When the size of the cookware is smaller, the cookware can be coupled with multiple said recesses, and the performance of the coil disk assembly 100 can also be fully exerted.
[0064] Specifically, in this embodiment, each turn of the special-shaped coil of the first coil winding 2 includes a plurality of first wire segments 21 and a plurality of second wire segments 22, a second wire segment 22 is arranged between two adjacent first wire segments 21, the middle portion of the first wire segment 21 is bent away from the middle portion of the mounting bracket 1, the first wire segment 21 forms the convex portion 20, and the second wire segment 22 forms the concave portion.
[0065] It can be understood that since the first coil winding 2 is formed by multiple turns of coils, the number of turns of the protrusion 20 is the same as the number of turns of the recess. When the size of the cookware is larger, the cookware can be coupled with multiple protrusions 20 and multiple recesses, and the number of coil turns involved in the coupling is the number of turns of the protrusion 20 or the recess. When the size of the cookware is slightly smaller, the cookware cannot cover all areas of the first coil winding 2, but when it can be coupled to multiple recesses, it can be coupled with multiple recesses, and the number of coil turns involved in the coupling is the number of turns of the recesses. Therefore, the number of coil turns coupled with large-sized cookware does not change much.
[0066] In the first embodiment, see Figures 1 to 3 Each of the first wire segments 21 is configured to be arc-shaped. This facilitates the winding of the first wire segment 21 and avoids introducing a sharp turning angle into the first wire segment 21. At a sharp turning angle, there is usually a large amount of heat generated, which may easily cause safety hazards.
[0067] In the first embodiment, the middle parts of the plurality of second wire segments 22 are bent toward the middle part of the mounting bracket 1. In this way, during the winding of the first coil winding 2, the convex part 20 and the concave part can be smoothly transitioned, and the wiring direction is consistent, which is conducive to simplifying the winding process and improving the winding efficiency.
[0068] In the second embodiment, see Figures 4 to 6 , each of the first wire segments 21 is configured as a plurality of linear wire segments connected in sequence, and the angle formed between two adjacent linear wire segments is configured to be greater than the angle formed by the extension directions of the two adjacent first wire segments 21. In this way, the plurality of linear wire segments are connected to form an arc-like line, so as to facilitate the winding of the first wire segment 21 and avoid introducing a sharp turning angle in the first wire segment 21. A variety of possibilities are provided for the winding form of the first coil winding 2.
[0069] In the third embodiment, see Figures 7 to 9 The middle parts of the plurality of second wire segments 22 are bent away from the middle part of the mounting bracket 1. The second wire segment 22 can be set to have the same curvature as the annular coil winding, so that the second wire segment 22 and the annular coil winding can form a large-sized heating area with the same current direction, which can be more efficient when coupled with a large-sized cookware.
[0070] In the fourth embodiment, see Figures 10 to 12 , each second wire segment 22 is arranged in a straight line. If the second wire segment 22 needs to be bent, a certain winding structure needs to be arranged on the mounting bracket 1 for the second wire segment 22 to be wound, which also increases the complexity of the winding process. By arranging each second wire segment 22 in a straight line, after the first wire segment 21 is wound, when it is extended and wound toward another adjacent winding structure for winding the first wire segment 21, it can be directly stretched over, thereby reducing the winding process. Alternatively, when the second wire segment 22 adopts a dense winding process, the complexity of the winding can be reduced.
[0071] Since the winding process of the first coil winding 2 is relatively complicated, the winding is more convenient when the size of the first coil winding 2 is large. However, at this time, the magnetic field strength inside the first coil winding 2 is relatively weak, and a heating blind area is easily formed. In order to compensate for the above-mentioned heating blind area, in one embodiment of the present invention, the coil disk assembly also includes a second coil winding 3 wound around the middle of the mounting bracket, and the first coil winding 2 is arranged on the periphery of the second coil winding 3. In this way, the second coil winding 3 is arranged on the inner side of the first coil winding 2 to form a continuous heating area, thereby improving the uniformity of heating of the coil disk assembly 100.
[0072] Furthermore, the first coil winding 2 and the second coil winding 3 can be controlled separately. When the pot is small, only the second coil winding 3 can be controlled to work. When the pot is large, the first coil winding 2 and the second coil winding 3 can be controlled to work at the same time.
[0073] Furthermore, the second coil winding 3 can be set to be circular or square, and can be designed according to actual conditions. Figure 7 In this embodiment, the second coil winding 3 is arranged in a circular shape; each turn of the first coil winding 2 includes a first wire segment 21 corresponding to the protrusion 20, and a second wire segment 22 connected to the first wire segment 21, and the middle part of each second wire segment 22 is bent away from the middle part of the mounting bracket 1, and each second wire segment 22 is arranged in parallel with the second coil winding 3. In this way, the directions of the magnetic fields generated by the second wire segment 22 and the corresponding parts of the second coil winding 3 are also parallel, which helps to reduce electromagnetic interference between coils, avoid unnecessary electromagnetic coupling and interference caused by the coils crossing or staggered, and affect the performance and stability of the circuit. At the same time, it can reduce energy loss, improve the efficiency of electromagnetic energy transmission, help reduce the energy consumption of the circuit, and optimize the performance of electromagnetic equipment.
[0074] In this embodiment, each turn of the coil of the first coil winding 2 includes a first wire segment 21 corresponding to the protrusion 20, and a second wire segment 22 connected to the first wire segment 21; a first winding structure for winding the first coil winding 2 is provided on the mounting bracket 1, and the first winding structure includes a first winding portion 11, and a plurality of second winding grooves 1b formed on one side of the mounting bracket 1; the first winding portion 11 is provided on one side of the mounting bracket 1, and a first winding groove 1a with a notch facing the circumferential side of the mounting bracket 1 is defined between the first winding portion 11 and the mounting bracket 1; wherein the first wire segment 21 of the first coil winding 2 is limited to the first winding groove 1a, and the plurality of second wire segments 22 of the first coil winding 2 are correspondingly provided in the plurality of second winding grooves 1b.
[0075] Thus, on the mounting bracket 1, the plurality of first wire segments 21 can be confined in the first winding groove 1a by side winding, and the plurality of second wire segments 22 can be wound in the second winding groove 1b by sparse winding.
[0076] Specifically, for the first embodiment described above, please refer to Figures 1 to 3 After the arc-shaped first wire segment 21 is confined in one of the first winding grooves 1a, when it is extended and wound toward another adjacent first winding groove 1a, it is sparsely wound through the second winding groove 1b arranged between the two adjacent first winding grooves 1a, wherein the extension direction of each second winding groove 1b can be set to be bent in the middle toward one side away from the middle of the mounting bracket 1.
[0077] Specifically, for the second embodiment described above, please refer to Figures 4 to 6After the first wire segment 21 connected by multiple straight wire segments is confined in one of the first winding grooves 1a, when it is extended and wound toward another adjacent first winding groove 1a, it is sparsely wound through the second winding groove 1b located between the two adjacent first winding grooves 1a.
[0078] In another embodiment, a plurality of third winding grooves 1c and a plurality of fourth winding grooves 1d are recessed on one side of the mounting bracket 1; a plurality of first wire segments 21 of the first coil winding 2 are correspondingly arranged in the third winding grooves 1c, and a plurality of second wire segments 22 of the first coil winding 2 are correspondingly arranged in the fourth winding grooves 1d. The specific forms of the third winding grooves 1c can also be various, that is, the third winding grooves 1c and the fourth winding grooves 1d can both be set as grooves with larger groove widths and larger intervals; the third winding grooves 1c and the fourth winding grooves 1d can both be set as grooves with smaller groove widths and smaller intervals, so as to achieve sparse winding and dense winding.
[0079] For the third embodiment described above, please refer to Figures 7 to 9 The third winding groove 1c and the fourth winding groove 1d can be set as wider grooves, the first wire segment 21 is sparsely wound in the third winding groove 1c, and the second wire segment 22 is sparsely wound in the fourth winding groove 1d.
[0080] For the fourth embodiment described above, please refer to Figures 10 to 12 The third winding groove 1c and the fourth winding groove 1d can be set as narrower grooves, the first wire segment 21 is tightly wound in the third winding groove 1c, and the second wire segment 22 is tightly wound in the fourth winding groove 1d.
[0081] To better understand the difference between sparse winding and dense winding, it should be noted that there are the following differences between sparse winding and dense winding: Coil arrangement: Sparse winding and dense winding refer to the arrangement of the wires in the coil. In sparse winding, the spacing between the wires is relatively large, and there is usually a certain gap between the wires. In dense winding, the spacing between the wires is relatively small, and the wires are closely arranged with almost no gaps. Wire length of the coil: Due to the large spacing in sparse winding, the length of the wire is relatively long. In dense winding, due to the close arrangement of the wires, the length of the wire is relatively short. Inductance characteristics of the coil: Sparse winding and dense winding affect the inductance characteristics of the coil. Sparse winding coils have a relatively smaller inductance than dense winding coils due to the large spacing between the wires. And dense winding coils have a relatively larger inductance than sparse winding coils due to the small spacing between the wires. Heat dissipation and electrical insulation of the coil: Dense winding coils have more difficulty in heat dissipation than sparse winding coils due to the close arrangement of the wires. In addition, the electrical insulation requirements between the wires of dense winding coils are higher, because the small spacing between the wires can easily lead to electrical insulation breakdown. Therefore, the choice of sparse winding or dense winding depends on the specific application requirements. Sparse winding can provide better heat dissipation performance and electrical insulation ability, and is suitable for high power or high frequency applications. Dense winding can provide larger inductance and smaller size, and is suitable for applications requiring high inductance. The utility model provides a variety of winding forms, and the appropriate winding method can be selected according to actual conditions.
[0082] The utility model also provides a cooking utensil, the cooking utensil includes the above-mentioned coil disk assembly 100. Since the cooking utensil includes the coil disk assembly 100, the specific structure of the coil disk assembly 100 refers to the above-mentioned embodiment. Since the coil disk assembly 100 of the cooking utensil adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.
[0083] Specifically, the cooking utensil includes an induction cooker or an induction cooker. Of course, it can also be other possible cooking utensil, such as an electric rice cooker or an electric pressure cooker, which can be determined according to actual conditions and is not limited in this embodiment of the specification.
