[0040] In existing square disks, if you want to increase the magnetic field and cover the entire square area, most of them use right-angle winding, that is, the winding at the corner is about 90 degrees, please refer to Figure 1 The coil disk shown in the figure, when working, causes the current direction of the two sides of the square coil to change suddenly at the corners, the induced magnetic field generated by the coil changes 90°, the direction of the magnetic field changes suddenly, and the partial components of the magnetic field generated by the same wire on both sides of the corner are offset, resulting in a weak magnetic field at the corner and a weak thermal field, which leads to blind spots in the four corners, uneven heating, blind spots in the four corners, and uneven heating.
[0041] In order to solve the above problems, the utility model provides a mounting bracket.

[0042] See also Figures 2 to 3The mounting bracket 1 is used for mounting the coil winding 2. The mounting bracket 1 has a plurality of side edges 11. A plurality of winding grooves a are formed on one side of the mounting bracket 1. Each winding groove a includes at least two straight groove segments a1 and a transition groove segment a2. The two straight groove segments a1 are arranged along the direction in which two adjacent side edges 11 of the mounting bracket 1 extend. The transition groove segment a2 connects the two straight groove segments a1 so that the angles formed at the connection points between the transition groove segment a2 and the two straight groove segments a1 are respectively set to be greater than the angle formed by the extension directions of the two straight groove segments a1. In the direction from the inside to the outside of the mounting bracket 1, the sizes of the plurality of transition groove segments a2 are gradually reduced.
[0043] It is understandable that, since the mounting bracket 1 is used for winding the coil winding 2 , and the coil winding 2 is generally wound in the winding groove a , the extension direction of the winding groove a also defines the shape of the coil winding 2 .
[0044] It should be noted that the slot spacing between the multi-turn winding slots a can be set to be sparse or dense, that is, the coil disk can be wound sparsely or densely, and the specific design can be based on actual conditions, and the embodiments of this specification do not limit this.
[0045] It should also be noted that the mounting bracket 1 can be set as a polygon, or a quasi-polygon, or a quasi-circular shape with multiple secants. Of course, other possible special-shaped shapes can also be used. In other words, when the special-shaped mounting bracket has multiple sides, the arrangement of the winding groove in this application can also be adopted. The specific arrangement can be determined according to the actual situation, and the embodiments of this specification do not limit this. Because the mounting bracket 1 has multiple sides 11, in order to enable the coil winding 2 to adapt to the mounting bracket 1 and cover the entire mounting bracket 1, the winding groove a is also adapted to the shape of the mounting bracket 1, and has a straight groove section a1 corresponding to the side 11, so that the magnetic field generated by the coil winding 2 can act on each corner corresponding to the mounting bracket 1.
[0046] For the convenience of the following description, the installation bracket 1 is set as a square bracket as an example for explanation.
[0047] In the technical solution provided by the utility model, the mounting bracket 1 has a plurality of side edges 11, and a plurality of winding grooves a are formed on one side of the mounting bracket 1, and each winding groove a includes at least two straight groove segments a1 and a transition groove segment a2, and the two straight groove segments a1 are arranged along the direction in which two adjacent side edges 11 of the mounting bracket 1 extend, and the transition groove segment a2 connects the two straight groove segments a1, so that the angles formed at the connection points between the transition groove segment a2 and the two straight groove segments a1 are respectively set to be greater than the angle formed by the extension directions of the two straight groove segments a1, so that the two straight groove segments a1 are transitioned through the transition groove segment a2, and when the coil winding 2 is wound on the winding The wire slot a will also extend along the extension direction of the winding slot a, so that the coil winding 2 can play a transition role in the wire segment corresponding to the transition slot segment a2, avoiding the sudden change of the current direction of the wire, reducing the degree of offset of the magnetic field component, alleviating the sudden change of the electromagnetic field, and making the thermal field more uniform. In addition, in the direction from the inside to the outside of the mounting bracket 1, the sizes of at least some of the multiple transition slot segments a2 are gradually reduced in sequence, so that the winding at the corner gradually changes into a shape close to a right angle, which can not only ensure that the sudden change of the electromagnetic field is alleviated and the heating is more uniform, but also cover the area of the entire mounting bracket 1, increase the heating area, and solve the problem of blind spots and uneven heating at the four corners of the existing square coil disk.
[0048] It should also be noted that "at least some of the multiple transition groove segments a2 are set to gradually decrease in size" can be understood as, in some embodiments, the sizes of all the transition groove segments a2 are set to gradually decrease in size, and the winding groove gradually fits the outer contour of the mounting bracket from the inside to the outside.
[0049] In other embodiments, the sizes of the transition groove segments a2 in the part close to the inner circle may be gradually reduced, and the sizes of the transition groove segments a2 in the part close to the outer circle area may be all set equally and consistent with the size of the transition groove segments a2 of the winding groove a in the outermost circle of the inner circle.
[0050] In the present embodiment, the multi-turn winding groove a includes a plurality of first winding grooves and a plurality of second winding grooves surrounding the periphery of the first winding grooves; in the direction from the inside to the outside of the mounting bracket 1, the sizes of the transition groove sections a2 of the plurality of second winding grooves are set to be gradually smaller. In order to allow the plurality of second winding grooves a2 to gradually fit the outer contour of the mounting bracket, the sizes of the transition groove sections a2 of the plurality of first winding grooves can be set to be the same, and the winding groove a can even be set to be close to a circular ring. Of course, the setting form of the winding groove a is not limited to the above examples. The technicians in the relevant field may make other changes under the inspiration of the technical essence of the embodiments of this specification, but as long as the functions and effects achieved are the same or similar to those of the embodiments of this specification, they should be covered within the protection scope of the embodiments of this specification.
[0051] Specifically, see Figure 3 In the first embodiment, the transition slot segment a2 is arranged in an arc shape, so that the arc conductor of the coil winding 2 corresponding to the transition slot segment a2 has a relatively shorter actual length between the conductors compared to a right angle. A shorter conductor length means that less current will encounter resistance when passing through the conductor, thereby reducing the overall resistance and enabling the contact area between the conductors to be controlled and reduced. Because the contact area is smaller, the resistance encountered by the current when flowing between the conductors will also be reduced accordingly, thereby reducing the resistance between the conductors.
[0052] Since the sizes of the multiple transition slot segments a2 are set to be gradually reduced, it can be achieved by reducing the length of the transition slot segment a2, or by reducing the radius of the transition slot segment a2. However, if the length of the arc is only reduced without adjusting the radius, the current density at the intersection of the wires may be too high. High current density may cause local heat concentration, increase coil loss, and even cause the risk of local arc discharge. In this embodiment, the transition slot segment a2 is set in an arc, and in the direction from the middle of the mounting bracket 1 to the outside, the radius of the multiple transition slot segments a2 is set to be gradually reduced. Such a setting makes the current more evenly distributed in the wire segments wound in the transition slot segment a2, which helps to reduce the heat concentration and coil loss that may be caused by excessive local current density, avoids excessive concentrated current at the intersection of the wires during current transition, helps to reduce the risk of hot spots in the induction cooker coil winding 2, and increases the stability and reliability of the system. At the same time, the resistance of the wire transition area can be reduced, thereby reducing the voltage drop of the wire, reducing energy loss, and improving the coil conduction efficiency.
[0053] Of course, the transition groove section a2 may adopt other shapes besides the arc shape, see Figure 4In the second embodiment, the transition slot segment a2 is arranged in a straight line. Of course, compared with a 90° right angle, the straight slot segment can shorten the actual length of the wire of the coil winding 2 corresponding to the transition slot segment a2, and can also reduce the resistance to a certain extent.
[0054] In order to make the magnetic field generated by the wire segment in the transition slot a2 fully generate energy efficiency, in this embodiment, the transition slot a2 is arranged in a straight line, and multiple transition slots a2 are arranged in parallel. In this way, the wire segments in the corresponding multiple transition slots a2 are arranged in parallel, so their magnetic field directions are also parallel, which helps to reduce the electromagnetic interference between the coil windings 2, avoid the coil windings 2 from crossing or staggered each other to cause unnecessary electromagnetic coupling and interference, 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 the electromagnetic device.
[0055] In this embodiment, the number of the plurality of sides 11 is greater than or equal to 3. That is, the mounting bracket 1 can be a quasi-triangular, quadrilateral, pentagonal or a special-shaped mounting bracket 1 with sides. Preferably, the mounting bracket 1 has four sides, and is a quasi-square bracket. Since the shells of most cooking utensils on the market are set to be square, the mounting bracket 1 can be matched with the shell of the cooking utensil, so that the electromagnetic heating coil disk has as large a heating area as possible through the coil winding wound in the quasi-square winding groove on the mounting bracket 1, and can provide a larger heating area for larger pots.
[0056] The utility model also provides a coil disk assembly 100, see Figure 5 The coil disk assembly 100 includes a mounting bracket 1 and a coil winding 2, wherein the mounting bracket 1 has a plurality of side edges 11; the coil winding 2 is wound on the mounting bracket 1, and the coil winding 2 includes a plurality of turns of coil, each turn of the coil includes two straight wire segments 21 and a chamfered wire segment 22, the two straight wire segments 21 are arranged along the direction in which the two side edges 11 of the mounting bracket 1 extend, and the chamfered wire segment 22 is adjacent to the two straight wire segments 21, wherein in the direction from the inside to the outside of the mounting bracket 1, at least some of the plurality of chamfered wire segments 22 are arranged to be gradually reduced in size.
[0057] The coil winding 2 is wound on the mounting bracket 1. The coil winding 2 can be wound sparsely, densely or even side-wound, or can be installed in other clamping or snap-fitting ways. Of course, the installation method of the coil winding 2 is not limited to the above examples. Technicians in the relevant field may make other changes under the inspiration of the technical essence of the embodiments of this specification, but as long as the functions and effects achieved are the same or similar to those of the embodiments of this specification, they should be covered within the protection scope of the embodiments of this specification.
[0058] It should also be noted that "at least some of the multiple chamfered wire segments 22 are gradually reduced in size" can be understood as, in some embodiments, the sizes of all the chamfered wire segments 22 are gradually reduced in sequence, and the coil winding gradually fits the outer contour of the mounting bracket from the inside to the outside.
[0059] In other embodiments, the sizes of the chamfered wire segments 22 near the inner circle may be gradually reduced, and the sizes of the chamfered wire segments 22 near the outer circle area may be all set equally and consistent with the sizes of the chamfered wire segments 22 of the coil winding in the outermost circle of the inner circle.
[0060] In the technical solution provided by the utility model, the mounting bracket 1 has multiple side edges 11, and the two straight wire segments 21 are transitioned by the chamfered wire segment 22 to avoid a sudden change in the current direction between the two straight wire segments 21, reduce the degree of cancellation of the magnetic field components, alleviate the sudden change of the electromagnetic field, and make the thermal field more uniform. In addition, in the direction from the middle of the mounting bracket 1 to the outside, the sizes of the multiple chamfered wire segments 22 are gradually reduced, so that the winding at the corner gradually changes to a shape close to a right angle, which can not only ensure that the sudden change of the electromagnetic field is alleviated and the heating is more uniform, but also cover the area of the entire mounting bracket 1, increase the heating area, and solve the problem of blind spots and uneven heating at the four corners of the existing square coil disk.
[0061] In the present embodiment, the multi-turn coil includes a plurality of first coil windings and a plurality of second coil windings surrounding the periphery of the first coil windings; in the direction from the inside to the outside of the mounting bracket 1, the sizes of the chamfered wire segments 22 of the plurality of second coil windings are set to be gradually smaller. In order to allow the plurality of second coil windings to gradually fit the outer contour of the mounting bracket, the sizes of the chamfered wire segments 22 of the plurality of first coil windings can be set to be identical, and the plurality of first coil windings can even be set to be close to a quasi-circular shape. Of course, the arrangement of the coil windings is not limited to the above examples, and technicians in the relevant field may make other changes under the inspiration of the technical essence of the embodiments of this specification, but as long as the functions and effects achieved are the same or similar to those of the embodiments of this specification, they should be covered within the protection scope of the embodiments of this specification.
[0062] Specifically, the chamfered wire segment 22 is arranged in a circular arc or a straight line.
[0063] See also Figure 6 When the chamfered wire segment 22 is set in an arc shape, compared with a right-angle transition, the chamfered wire segment 22 of the coil winding 2 makes the actual length between the wires relatively shorter. A shorter wire length means that less current will encounter resistance when passing through the wire segment, thereby reducing the overall resistance and allowing the contact area between the wire segments to be controlled and reduced. Because the contact area is smaller, the resistance encountered by the current when flowing between the wire segments will also be reduced accordingly, thereby reducing the resistance between the wires.
[0064] Furthermore, the chamfered wire segment 22 is arranged in an arc shape, and in the direction from the middle of the mounting bracket 1 to the outside, the radius of the plurality of chamfered wire segments 22 is arranged to be gradually reduced. Such an arrangement allows the current to be more evenly distributed in the chamfered wire segment 22, which helps to reduce the heat concentration and coil loss that may be caused by excessive local current density, avoids excessive concentrated current at the intersection of the wires during current transition, helps to reduce the risk of hot spots in the induction cooker coil winding 2, and increases the stability and reliability of the system. At the same time, the resistance of the wire transition area can be reduced, thereby reducing the voltage drop of the wire, reducing energy loss, and improving the coil conduction efficiency.
[0065] See also Figure 7 When the chamfered wire segments 22 are arranged in a straight line, multiple chamfered wire segments 22 are arranged in parallel. Thus, the magnetic field directions between the multiple chamfered wire segments 22 are also parallel, which helps to reduce the electromagnetic interference between the coil windings 2 and avoid unnecessary electromagnetic coupling and interference caused by the coil windings 2 crossing or staggered, which affects the performance and stability of the circuit.
[0066] In this embodiment, the mounting bracket 1 is set as the above-mentioned mounting bracket 1. The mounting bracket 1 has multiple side edges 11, and multiple winding grooves a are formed on one side of the mounting bracket 1. Each winding groove a includes at least two straight groove segments a1 and a transition groove segment a2. The two straight groove segments a1 are arranged along the direction in which two adjacent side edges 11 of the mounting bracket 1 extend. The transition groove segment a2 connects the two straight groove segments a1, so that the angles formed at the connecting points of the transition groove segment a2 and the two straight groove segments a1 are set to be greater than the angle formed by the extension direction of the two straight groove segments a1, wherein in the direction from the middle of the mounting bracket 1 to the outside, the sizes of the multiple transition groove segments a2 are set to be gradually reduced in sequence. In this way, the coil winding 2 is directly wound in the winding groove a, which can meet the winding form requirements of the coil winding 2 and achieve the purpose of adjusting the magnetic field distribution.
[0067] 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.
[0068] Specifically, the cooking utensil includes an induction cooker, an induction cooker or an electric pressure cooker. When the cooking device is an induction cooker, a square-shaped frying pan or the like can be adapted so that the bottom of the square cooker can be heated evenly and a relatively uniform magnetic field can be induced at the corners. When the cooking device is an induction cooker, a plurality of the coil disk assemblies 100 can be provided to form multi-head heating, and when the mounting bracket 1 is set to be square-shaped, it can be adapted to the square shape of the existing induction cooker, so that the induction cooker can have as large a heating area as possible. Of course, the arrangement form and application scenario of the coil disk assembly 100 and the mounting bracket 1 are not limited to the above examples, and can be specifically designed according to actual conditions, and the embodiments of this specification do not limit this.
[0069] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention.
