Further, the extending direction of the first side of the coil panel 110 is the same as the second direction, and the extending direction of the second side of the coil panel 110 is the same as the first direction, that is, the first sides of two adjacent coil panels 110 are limited to be arranged oppositely, and when the length of the first side is greater than that of the second side, the occupied length of the arranged coil panels 110 is smaller, so that the problems that the length of the electromagnetic heating device is too long when the coil panel 110 is applied to the electromagnetic heating device, the volume of the electromagnetic heating device is too large and the like are avoided, and the distribution of the coil panels 110 is reasonable, and the heating range is large.
Specifically, when the lengths of the first and second sides of the coil disk 110 are equal, the coil disk 110 may have a shape similar to a square; when the length of the first side of the coil disk 110 is greater than the length of the second side, the coil disk may have a shape similar to a rectangle or an ellipse.

Specifically, the first distance D1 ranges from 2mm to 20 mm. That is, it is specifically defined that the first distance D1 is greater than or equal to 2mm and less than or equal to 20mm, that is, the distance between two adjacent coil panels 110 arranged at intervals in the first direction is greater than or equal to 2mm and less than or equal to 20mm, and the lower limit value can ensure that the distance between the two adjacent coil panels 110 in the first direction is ensured, so that the magnetic fields generated by the coil windings 120 at the positions adjacent to the two coil panels 110 are distributed in a very small range after being superposed, which can cause overlapping of a large area of heating regions, and avoid uneven heat in the heating process caused by uneven magnetic field strength, and even cause the problem that the heating concentrated part is easily blurred; the upper limit value may limit the distance between two adjacent coil panels 110 in the first direction, so as to indirectly limit the space occupied by the coil panel assembly 100 in the first direction, so as to arrange the plurality of coil panels 110 in a relatively compact space, thereby enabling the coil panel assembly 100 to be applied to a relatively small electromagnetic heating device.
Further, as shown in fig. 1, the second distance D2 has a value ranging from 2mm to 30 mm. That is, the second distance D2 is specifically defined to be greater than or equal to 2mm and less than or equal to 30mm, that is, the distance between the centers of two adjacent coil panels 110 in the second direction is greater than or equal to 2mm and less than or equal to 30mm, and the lower limit value can ensure that the two adjacent coil panels 110 have a misalignment in the second direction, which helps to increase the maximum coverage area of the coil windings 120 of the coil panel assembly 100 formed by combining a plurality of coil panels 110 and increase the heating area range of the coil panel assembly 100; the upper limit value may limit the displacement dimension of the two adjacent coil panels 110 in the second direction, so as to indirectly limit the space occupied by the coil panel assembly 100 in the second direction, so as to arrange the plurality of coil panels 110 in a more compact space, thereby enabling the coil panel assembly 100 to be applied to a smaller electromagnetic heating device.
EXAMPLE III
As shown in fig. 2, on the basis of the first embodiment or the second embodiment, the third embodiment proposes a coil panel assembly 100, and further defines that the coil panel 110 includes the coil winding 120, and the coil winding 120 is defined by size. Specifically, the value of the dimension L1 of the coil winding 120 in the second direction ranges from 70mm to 300mm, and the lower limit value can ensure that the coil winding 120 has a sufficient heating length, 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 length of the coil winding 120, so as to limit the space occupied by the coil disc assembly 100 in the second direction, 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 coil winding 120 along the first direction is in the range of 35mm to 150mm, 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, so as to limit the space occupied by the coil disc assembly 100 in the second direction, thereby enabling the coil disc assembly 100 to be applied to a smaller electromagnetic heating device.
Further, as shown in fig. 2, a dimension L1 of the coil winding 120 in the second direction is greater than a dimension W1 of the coil winding 120 in the first direction, so that the extending direction of the longer side of the coil winding 120 is the same as the extending direction of the first side of the coil panel 110, and the extending direction of the shorter side of the coil winding 120 is the same as the extending direction of the second side of the coil panel 110, so that the coil winding 120 is distributed over the surface of the coil panel 110 as much as possible, the heating area of the coil panel 110 is ensured, the heating area of the coil winding 120 during operation can cover most of the position on the coil panel 110, and the coil panel assembly 100 with a larger heating area is obtained.
It is understood that, in order to ensure the heating area of the coil panel 110, the coil winding 120 may be designed to cover the surface of the coil panel 110 as much as possible, so that the heating area of the coil winding 120 during operation can cover most of the position on the coil panel 110, thereby obtaining the coil panel assembly 100 with a larger heating area. Specifically, the coil winding 120 is a multi-turn close-wound winding structure, and the multi-turn coils are closely arranged. It should be noted that, in order to make the coil winding 120 spread over the surface of the coil disk 110 as much as possible, the coil winding 120 is arranged to fit the coil disk 110, a relatively long side of the coil winding 120 is arranged to be opposite to a first side of the coil disk 110, and a relatively short side of the coil winding 120 is arranged to be opposite to a second side of the coil disk 110. Specifically, the coil winding 120 of the present application may have various shapes, such as an oval shape, a rectangle shape, a square shape, an irregular pattern in which the outer contour includes two straight line segments and two arc segments, and the like. When the coil winding 120 has an elliptical shape, a relatively long side of the coil winding 120 corresponds to an extending direction of a major axis of the ellipse, and a relatively short side of the coil winding 120 corresponds to an extending direction of a minor axis of the ellipse. When the coil winding 120 has a rectangular shape, a relatively long side of the coil winding 120 corresponds to a long side of the rectangular shape, and a relatively short side of the coil winding 120 corresponds to a short side of the rectangular shape. When the outer contour of the coil winding 120 includes two straight line segments and two arc segments, specifically, each straight line segment is connected between two arc segments, that is, the coil winding 120 is in an ellipse-like shape, wherein the outer contour dimension of the coil disc 110 in the extending direction of the straight line segment is larger than the outer contour dimension of the coil disc 110 in the extending direction of the arc segment, the relatively longer side of the coil winding 120 corresponds to the setting side of the straight line segment, and the relatively shorter side of the coil winding 120 corresponds to the setting side of the arc segment.
Further, as shown in fig. 2, any one of the coils in the coil winding 120 includes two first wire segments 122 and two second wire segments 124, the two first wire segments 122 are oppositely disposed and extend in the second direction, that is, the two first wire segments 122 extend along the first side of the coil panel 110; the two second wire segments 124 are oppositely disposed, and the ends of the two second wire segments 124 are connected to the end of at least one first wire segment 122, so that the first wire segment 122 is connected to the second wire segment 124 to form a coil, and the multiple coils are tightly wound to form the coil winding 120.
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 122 and the second wire segment 124 included in any coil of the coil winding 120 are integrally formed, and are divided into regions for distinguishing different positions.
Further, as shown in fig. 2, the first wire segments 122 are linearly arranged, so that the first wire segments 122 at the outermost position of the coil winding 120 are distributed on the edge of the support 130 of the coil panel 110 as much as possible, thereby making the most of the space of the support 130 of the coil panel 110, increasing the coverage area of the coil winding 120 on the support 130 of the coil panel 110, and increasing the heating area of the coil panel 110. Moreover, when the two coil panels 110 are combined together, because the first sides of the two coil panels 110 are opposite, that is, the linear first wire sections 122 of the two coil panels 110 are opposite, the area of the blind area not covered by the coil winding 120 between the two adjacent coil panels 110 is smaller, and compared with the combined heating blind area of the two coil panels 110 in which the first wire sections 122 are curved in the related art, the area covered by the coil winding 120 of the coil panel assembly 100 and the heating area 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) above the coil panel assembly 100 is increased, the heating power is increased, the heating efficiency is increased, the product quality risk is reduced, and the service life of the product is prolonged.
Further, as shown in fig. 2, the second wire segments 124 are arc-shaped, two arc-shaped second wire segments 124 and two linear first wire segments 122 form a coil similar to an ellipse in one turn, and a plurality of turns of wires with the same shape and different sizes are sequentially connected to form the coil winding 120.
Further, the second wire segments 124 may be linear, the joints of the two first wire segments 122 and the two second wire segments 124 form an arc, the two linear second wire segments 124, the two linear first wire segments 122, and the arc connecting segments between the first wire segments 122 and the second wire segments 124 form a coil similar to a rectangular coil in one turn, and a plurality of turns of wires having the same shape and different sizes are sequentially connected to form the coil winding 120. The arc is formed at the joint of the first wire section 122 and the second wire section 124, so that 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.

For example, when the number of the coil panels 110 arranged in the first direction is greater than or equal to three, the plurality of coil panels 110 arranged in the first direction are numbered by a natural number, and the positions of two adjacent odd-numbered or two adjacent even-numbered coil panels 110 in the second direction are the same, so that the plurality of coil panels 110 can be distributed in a staggered manner within a certain size range in the second direction, that is, the effective heating area of the coil panel assembly 100 formed by combining the plurality of coil panels 110 is enlarged, and the magnetic field intensity distribution of the coil panel assembly 100 formed by combining the plurality of coil panels 110 is improved, so that the positions of the two adjacent coil panels 110 where the magnetic fields are stronger do not coincide, and the product performance is optimized; and the space occupied by the coil panel assembly 100 in the second direction is limited so as to arrange the plurality of coil panels 110 in a more compact space, so that the coil panel assembly 100 can be applied to a smaller electromagnetic heating device.

Specifically, the bracket 130 is injection molded using a plastic material. 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.
