For example, the bracket 130 may be made of Polybutylene terephthalate (PBT), Polyethylene terephthalate (PET), Acrylonitrile Butadiene Styrene (ABS), Bulk Molding Compound (BMC), and plastic materials. The coil windings 120 are attached to a support 130. A multi-strand wire formed by twisting a plurality of aluminum wires or copper wires is tightly wound to form the coil winding 120. In the actual process of manufacturing the coil winding 120, for example, the winding manner of the coil winding 120 on the support 130 includes: (1) the wire is directly wound on the support 130, and a protrusion 134 may be disposed on the support 130, and the protrusion 134 is a boss, through which the shape of the coil winding 120 is controlled. For example, if the projection is elliptical, the inner circumference of the coil winding 120 is elliptical, and if the projection is square, the inner circumference of the coil winding 120 is square. (2) The coil winding 120 may be separately wound and formed and then mounted on the bracket 130, and the shape of the inner ring of the coil winding 120 is controlled by the shape of the winding tool.

EXAMPLE III

As shown in fig. 3, 4, 5, and 6, on the basis of the second embodiment, the third embodiment provides a coil panel assembly 100, and specifically defines that the plurality of coil windings 120 are distributed on the same horizontal plane, and the first sides of two adjacent coil windings 120 are opposite, that is, when the plurality of coil windings 120 are combined and arranged, the second sides of the coil windings 120 are overlapped, so that the occupied length of the plurality of coil windings 120 after being combined and arranged is smaller, and the problems that the length of the electromagnetic heating device is too long when the coil windings 120 are applied to the electromagnetic heating device, the volume of the electromagnetic heating device is too large, and the like are avoided, so that the distribution of the plurality of coil windings 120 is reasonable, and the heating range is large.

Further, as shown in fig. 2, the dimension L1 of the first side of the coil winding 120 ranges from 100mm to 300mm, and the lower limit value ensures that the coil winding 120 has a sufficient heating length, so that the heating range of the coil winding 120 is at least suitable for the small-sized cookware in common use; the upper limit may limit the length of the coil winding 120, so as to limit the space occupied by the coil disc assembly 100, thereby enabling the coil disc assembly 100 to be applied to a smaller electromagnetic heating device. Further, the value of the dimension W1 of the second side of the coil winding 120 ranges from 25mm to 240mm, and the lower limit value can ensure that the coil winding 120 has a sufficient heating width after the plurality of coil panels 110 are combined, so that the heating range of the coil winding 120 can be at least suitable for common small-sized cookware; the upper limit may limit the width dimension of the coil winding 120, thereby limiting the space occupied by the coil disc assembly 100, such that the coil disc assembly 100 may be applied to a smaller electromagnetic heating device.

Within this range, on the one hand, the upper limit value of the dimension W1 of the second side of the coil winding ensures that the dimension L1 of the first side of the coil winding is larger than the dimension W1 of the second side of the coil winding, so that it is possible to ensure a structure in which the coil winding 120 is integrally formed long and short in both directions; on the other hand, the lower limit of the dimension W1 of the second side of the coil winding limits the dimension L1 of the first side of the coil winding, so as to limit the space occupied by the coil disc assembly 100 in the length direction of the coil winding 120, so that the difference between the dimension W1 of the second side of the coil winding and the dimension L1 of the first side of the coil winding is not too large, and the dimension of the coil winding 120 is reasonable.

In a specific embodiment of the present invention, as shown in fig. 3, it is further defined that a plurality of coil windings 120 are connected in parallel, so that any one of the plurality of coil windings 120 can work independently, and when one coil winding 120 is used alone for heating, the heating of the small pot can be realized; of course, the coil windings 120 can also work together after being connected in parallel, and the coil windings 120 are suitable for heating large cookware when working together, so that the coil panel assembly 100 can be applied to cookware with various sizes and shapes, and the utilization rate and application range of products are improved. Further, the inductance of the coil winding 120 ranges from 80 μ H to 160 μ H. Within this range, the power of the plurality of coil windings 120 after being energized in parallel or individually is made to meet the requirement, which is suitable for the requirement of the electromagnetic heating device.

Specifically, the test conditions of the inductance of the coil winding 120 are as follows: 1KHZ/1V, no metal was placed at the bottom of coil winding 120 during testing.

Further, the inductance of the coil winding 120 ranges from 30 μ H to 80 μ H.

The first wire segment 121 is arranged to extend in the same direction as the first side, that is, the first wire segment 121 extends in the same direction as the first side of the coil winding that is relatively long. Further, the first wire segment 121 is arc-shaped or linear, the second wire segment 122 is arc-shaped or linear, and when the first wire segment 121 and the second wire segment 122 are both arc-shaped, any coil is oval; when the first wire segments 121 and/or the second wire segments 122 are linear, the first wire segments 121 and/or the second wire segments 122 at the outermost rings of the coil windings 120 can be distributed on the edge of the support 130 of the coil panel 110 as much as possible, so that the space of the support 130 of the coil panel assembly 100 is utilized to the maximum extent, the coverage area of the coil windings 120 on the support 130 is increased, and the heating area of the coil panel 110 can be increased. Moreover, when the first wire segments 121 are linear and the coil windings 120 are combined together, since the first sides of the coil windings 120 are opposite, that is, the linear first wire segments 121 of the coil windings 120 are opposite, the area of the coil windings 120 between two adjacent coil windings 120 that do not cover the blind area is smaller, and the heating blind area is smaller than that of the combined heating blind area of two coil panels 110 in which the first wire segments 121 are curved in the related art, so that the covering area and the heating area of the coil windings 120 of the coil panel assembly 100 are increased, the heating blind area of the coil panel assembly 100 is reduced, the coupling resistance or inductance of a heating device (e.g., a cooker) above the coil panel assembly 100 is increased, the heating power is increased, the heating efficiency is improved, the product quality risk is reduced, and the service life of the product is prolonged.

Further, as shown in fig. 8, 9, 10 and 11, any coil of the coil winding 120 further includes a connection segment 123 connecting the first wire segment 121 and the second wire segment 122, and the connection segment 123 is arc-shaped, so that the wire can be prevented from having a sharp bending angle, the coil winding 120 can be prevented from being broken, and the service life of the coil winding 120 can be prolonged.

For example, as shown in fig. 5, 8 and 10, in the case where two first wire segments 121 are linear and two second wire segments 122 are arc-shaped, the two arc-shaped second wire segments 122 and the two linear first wire segments 121 form a coil of one turn similar to an ellipse, and a plurality of turns of wires having the same shape and different sizes are sequentially connected to form the coil winding 120.

For example, as shown in fig. 6, 9 and 11, when two first lead segments 121 are linear and two second lead segments 122 are linear, the connection point between the two first lead segments 121 and the two second lead segments 122 is an arc-shaped connection segment 123, the two linear second lead segments 122, the two linear first lead segments 121, and the arc-shaped connection segment 123 between the first lead segments 121 and the second lead segments 122 form a coil similar to a rectangle in one turn, and a plurality of turns of leads having the same shape and different sizes are sequentially connected to form the coil winding 120.

It is to be understood that, although the description has been given by taking the first wire segment 121 as a straight line and the second wire segment 122 as an arc or a straight line as an example, the first wire segment 121 and the second wire segment 122 may take other forms, for example, the first wire segment 121 may take an arc shape, the second wire segment 122 may take a straight line shape, one of the first wire segment 121 and the second wire segment 122 may take a straight line shape, the other may take a wavy shape, one of the first wire segment 121 and the second wire segment 122 may take a straight line shape, and the other may take a straight line shape but may be slightly bent, which are also embodiments of the present invention, and these implementations and other realizable manners will be obvious to those skilled in the art.

It is understood that the coil winding 120 is formed by winding a wire, and the coils of the coil winding 120 are connected in sequence. The first wire segment 121, the second wire segment 122 and the connecting segment 123 included in any coil of the coil winding 120 are integrally formed, and are divided into regions for distinguishing different positions.

As shown in fig. 5, 6, 8, 9, 10 and 11, in an embodiment of the present invention, the first wire segment 121 is further formed in a straight shape, and the length L2 of the first wire segment 121 is equal to or less than 4/5 of the dimension L1 of the first side of the coil winding; and/or the second wire segment 122 is linear, and the length W2 of the second wire segment 122 is less than or equal to 4/5 of the dimension W1 of the second side of the coil winding.

In this embodiment, it is further limited that the first wire segment 121 is linear, and the length L2 of the first wire segment 121 is less than or equal to 4/5 of the size L1 of the first side of the coil winding, that is, as shown in fig. 10 and 11, the multiple turns of the first wire segment 121 form a first straight-side region M1, and the length of the first straight-side region M1 is less than 4/5 of the entire length of the coil winding 120, within this range, the connection segment 123 can have a sufficient installation space, the distribution ratio of the straight-side region and the arc-shaped region can be ensured, the excessively long first straight-side region M1 is avoided, which results in an excessively small radian of the connection segment 123, and the wire can be avoided having a sharp bending angle, thereby avoiding the coil winding 120 from being broken and prolonging the service life of the coil winding 120. And/or, the second wire section 122 is linear, the length W2 of the second wire section 122 is less than or equal to 4/5 of the size W1 of the second side of the coil winding, that is, the multiple circles of the second wire section 122 form a second straight side region M2, the length of the second straight side region M2 is less than 4/5 of the whole width of the coil winding 120, in this range, the connecting section 123 can have enough setting space, the distribution rate of the linear section and the arc section can be ensured, the phenomenon that the radian of the connecting section 123 is too small due to the overlong second straight side region M2 is avoided, the wire can be prevented from having a sharp bending angle, the coil winding 120 is prevented from being broken, and the service life of the coil winding 120 is prolonged.

It should be noted that, as shown in fig. 10, when the first wire segment 121 is linear and the second wire segment 122 is arc-shaped, the first straight region M1 is formed by the plurality of turns of the first wire segment 121, and the arc region M3 is formed by the plurality of turns of the second wire segment 122.

In this embodiment, it is further defined that the first wire segment 121 is linear, and the first wire segments 121 of the plurality of coil windings 120 are parallel, so that the space occupied by the plurality of coil windings 120 after being arranged is smaller. For example, the first wire sections 121 of two adjacent coil windings 120 in the plurality of coil windings 120 are oppositely arranged, and the first wire sections 121 are linear, and the linear first wire sections 121 of the plurality of coil windings 120 are opposite, so that the area of the coil windings 120 between the two adjacent coil windings 120, which does not cover a blind area, is smaller, and the heating blind area is smaller compared with the combined heating blind area of two coil panels 110 in which the first wire sections 121 are curved in the related art, thereby increasing the covering area and the heating area of the coil windings 120 of the coil panel assembly 100, reducing the heating blind area of the coil panel assembly 100, increasing the coupling resistance or inductance of a heating appliance (e.g., a cooker) at a position above the coil panel assembly 100, improving heating power, improving heating efficiency, reducing product quality risk, and prolonging the service life of the product.

As shown in fig. 6, 9 and 11, in an embodiment of the present invention, the second wire segments 122 are further linear, and the second wire segments 122 of the plurality of coil windings 120 are parallel.

For example, the second wire segments 122 of two adjacent coil windings 120 in the plurality of coil windings 120 are oppositely arranged, and the second wire segments 122 are in a linear shape, because the linear second wire segments 122 of the plurality of coil windings 120 are oppositely arranged, the area of the coil winding 120 between the two adjacent coil windings 120, which does not cover a blind area, is smaller, compared with the combined heating blind area of two coil panels 110 in which the second wire segments 122 are in a curved shape in the related art, so that the covering area and the heating area of the coil windings 120 of the coil panel assembly 100 are increased, the heating blind area of the coil panel assembly 100 is reduced, the coupling resistance or inductance of a heating appliance (e.g., a cooker) at a position above the coil panel assembly 100 is increased, the heating power is increased, the heating efficiency is improved, the product quality risk is reduced, and the service life of the product is prolonged.
