A coil disk assembly 100 and an electromagnetic heating apparatus provided according to some embodiments of the present invention are described below with reference to fig. 2 to 8.

Example one

As shown in fig. 2 and 7, an embodiment of the first aspect of the present invention provides a coil panel assembly 100, the coil panel assembly 100 includes a plurality of coil windings 120 arranged at intervals, each coil winding 120 includes a first side and a second side orthogonal to each other and extending along a horizontal direction, the length of the first side is greater than the length of the second side, further, each coil winding 120 includes a plurality of coils, each coil in the coil windings 120 includes two first wire segments 122 and two second wire segments 124, the two first wire segments 122 are disposed oppositely, the two second wire segments 124 are disposed oppositely, and ends of the two second wire segments 124 are connected with an end of at least one first wire segment 122, so that the first wire segments 122 are connected with the second wire segments 124 to form a coil, and the plurality of coils are tightly wound to form the coil windings 120. The first wire segments 122 are arranged in the same extending direction as the first side, and the first wire segments 122 are linear, so that the first wire segments 122 on the outermost ring of the coil winding 120 can be distributed on the edge of the bracket 130 of the coil panel 110 as much as possible, thereby utilizing the space of the bracket 130 of the coil panel assembly 100 to the maximum extent, increasing the covering area of the coil winding 120 on the bracket 130, and increasing the heating area of the coil panel 110. Moreover, as shown in fig. 2, when the plurality of coil windings 120 are combined together, since the first sides of the plurality of coil windings 120 are opposite, that is, the linear first lead sections 122 of the plurality of coil windings 120 are opposite, the area of the heating blind area Q2 uncovered by the coil winding 120 between two adjacent coil windings 120 is smaller, compared with the combined heating blind area Q1 of the two coil panels 110 in which the first lead sections 122 are curved as shown in fig. 1, the covered area and the heating area of the coil winding 120 of the coil panel assembly 100 are increased, the heating blind area Q2 of the coil panel assembly 100 is reduced, the coupling resistance or inductance of a heating appliance (e.g., a pot) at a position 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.

It should be noted that, in order to visually see the difference between the covered blank area of the coil winding of the coil disc assembly provided in the present application and the covered blank area of the coil winding of the coil disc assembly in the related art, as shown in fig. 1 and fig. 2, the portion where the range indicated by the dotted circle in fig. 1 overlaps with the coil disc assembly 100' is the covered blank area of the coil winding in the related art, that is, the heating blind area Q1, and the portion where the range indicated by the dotted circle in fig. 2 overlaps with the coil disc assembly 100 is the covered blank area of the coil winding in the present application, that is, the heating blind area Q2, as is obvious by comparing the heating blind area Q1 in the related art shown in fig. 1 with the heating blind area Q2 in the present application shown in fig. 2, the heating blind area Q2 in the present application is smaller than the heating blind area Q1 in the related art, so that the coil disc assembly in the present application is compared with the solution in the related art, under the condition of coil windings based on the same form, the coil panel assembly can effectively reduce the blank area of the coil panel assembly covered by the coil windings, so that the coil panel assembly 100 can increase the coupling resistance or inductance of a heating appliance (such as a cooker) above the coil panel assembly 100, improve the heating power, improve the heating efficiency, reduce the product quality risk and prolong the service life of the product.

It can be understood that, when the square electromagnetic heating device (such as an electromagnetic cooker) is applied to a square electromagnetic heating device (such as an electromagnetic cooker) commonly used in the related art, based on the condition that the length of the first side of the coil winding 120 is greater than the length of the second side, the circular coil winding 120 in the related art is changed into a structure that one side of the structure is relatively longer and one side of the structure is relatively shorter, and the coil windings 120 with a plurality of structures are arranged in a combined manner, so that the space utilization rate of the square electromagnetic cooker in the related art can be improved, and the heating range and the heating uniformity of a product can be improved. Further, as shown in fig. 2 and 7, the first sides of the 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 length occupied by the plurality of coil windings 120 after combination and arrangement is small, 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 size of the electromagnetic heating device is too large, and the like are avoided, and the plurality of coil windings 120 are reasonably distributed and have a large heating range.

Further, by arranging the coil panel assembly 100 to include the plurality of coil windings 120, the overall heating area of the coil panel assembly 100 is large, the coil panel assembly 100 may be applied to most of pots in the existing markets such as a circular pot and a square pot, and may also be applied to heating a special-shaped pot (such as an oval shape), and the heating area is maximized.

It is understood that any one of the coil windings 120 of the plurality of coil panels 110 can be used alone, and when one coil winding 120 is used alone for heating, the heating of the small pot can be realized; and a plurality of coil windings 120 are applicable to big pan heating when working together to make coil panel subassembly 100 can be applied to the pan of various different sizes, shape, promote the utilization ratio and the application scope of product.

Specifically, the coil winding 120 having the first side and the second side of the present application may have various shapes, for example, an oval shape, a rectangular 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 first side of the coil winding 120 corresponds to an extending direction of a major axis of the ellipse, and a second 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 first side of the coil winding 120 corresponds to a longer side of the rectangular shape, and a second side of the coil winding 120 corresponds to a shorter 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 size of the coil panel 110 in the extending direction of the straight line segment is larger than the outer contour size of the coil panel 110 in the extending direction of the arc segment, the first side of the coil winding 120 corresponds to the setting side of the straight line segment, and the second side of the coil winding 120 corresponds to the setting side of the arc segment. It should be noted that the coil winding 120 is a multi-turn tightly wound structure, and the multi-turn coils are closely arranged.

Further, as shown in fig. 2, 3 and 4, 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, as shown in fig. 5, the second wire segment 124 may be linear, the connection portions 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 connection segment 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.

Example two

As shown in fig. 2, on the basis of the first embodiment, the second embodiment proposes a coil disc assembly 100, and specifically defines a length of the first wire segment 122 of the innermost coil of the coil winding 120 and a range of values of a distance between two first wire segments 122 of the innermost coil of the coil winding 120. Specifically, the length of the first wire segment 122 of the innermost coil of the coil winding 120 ranges from 50mm to 200mm, 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 value may limit the length of the coil winding 120, so as to limit the space occupied by the coil disc assembly 100 in the length direction of the coil winding 120, thereby enabling the coil disc assembly 100 to be applied to a smaller electromagnetic heating device. Further, the distance between the two first wire segments 122 of the innermost coil of the coil windings 120 ranges from 10mm to 40mm, and the lower limit value can ensure that the multiple coil windings 120 have sufficient heating width after being combined, so that the heating range of the coil windings 120 can be at least suitable for common small-sized cookware; the upper limit value 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 width direction of the coil winding 120, thereby enabling the coil disc assembly 100 to be applied to a smaller electromagnetic heating device. Moreover, the value range of the length of the first wire segment 122 does not overlap with the value range of the distance between the two first wire segments 122, that is, the length of the first wire segment 122 is greater than the distance between the two first wire segments 122, so as to ensure that the coil winding 120 forms a structure with one long and one short.

It is understood that the coil winding 120 is formed by winding a wire, and a plurality of turns of the wire 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. 4 and 5, the length of the first wire section 122 of the innermost coil of the coil winding 120 is set as a coil winding length L1, the distance between the two first wire sections 122 of the innermost coil of the coil winding 120 is set as a coil winding length W1, the ratio of the coil winding length L1 to the coil winding length W1 is greater than 1 and less than or equal to 20, and the lower limit of the ratio of the coil winding length L1 to the coil winding length W1 ensures that the coil winding length L1 is greater than the coil winding length W1, so that the coil winding 120 can be ensured to be integrally formed into a structure which is one long and one short in two directions; the upper limit of the ratio of the coil winding length L1 to the coil winding length W1 may limit the size of the coil winding length L1, so as to limit the space occupied by the coil disc assembly 100 in the length direction of the coil winding 120, thereby enabling the coil disc assembly 100 to be applied to a smaller electromagnetic heating device.

EXAMPLE III

As shown in fig. 6, 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 further includes a bracket 130, the bracket 130 is used for mounting the coil winding 120, and the bracket 130 plays a role of supporting and fixing. Further, the coil panel 110 further includes a magnetic member 140, and the magnetic member 140 is disposed on a side of the coil winding 120 holder 130 facing away from the coil winding 120 corresponding to the coil winding 120. The magnetic member 140 may function to change the magnetic field strength and the local magnetic field direction. The magnetic member 140 may be made of a soft magnetic ferrite material and/or a manganese-zinc ferrite material. Specifically, since the magnetic resistance of the magnetic element 140 is small and the air magnetic resistance is large, the magnetic field is influenced by the magnetic element 140 and mostly gathers at the magnetic element 140, so that the magnetic field intensity and the magnetic field direction can be changed.

Further, the magnetic member 140 is provided to enhance the magnetic field strength, so that the magnetic lines generated by the coil winding 120 are gathered, and the heating efficiency is improved.

Further, as shown in fig. 6, the magnetic member 140 may be divided into at least two parts according to the magnetic field strength generated by the coil winding 120 at the position, the first part of the magnetic member 140 has a larger area and is disposed on the bracket 130 corresponding to the position where the magnetic field strength generated by the coil winding 120 is stronger; the second partial magnetic member 140 has a smaller area and is disposed on the bracket 130 corresponding to a position where the magnetic field generated from the coil winding 120 is weaker. Under the effect of magnetism spare 140 can make the magnetic field intensity of coil panel subassembly 100 each department relatively even to can reduce the magnetic field intensity difference in the different regions, promote the homogeneity of coil winding 120 heating, make coil panel subassembly 100 heating in-process heat is even, avoid the heating to concentrate the problem of sticking with paste the end that causes easily.

Further, the magnetic member 140 is formed of a plurality of magnetic conductors distributed at intervals. The magnetic part is composed of a plurality of magnetizers, so that the space arrangement requirement can be met. On the premise of meeting the requirement of the magnetic field intensity, the magnetic field intensity can be adapted to the residual space position of the bracket 130 of the coil winding 120 through the splicing and the arrangement of a plurality of magnetizers. If the magnetic member 140 is a whole, when the magnetic member 140 is assembled on the coil winding 120 support 130, the arrangement of other components will make it difficult to satisfy the large assembly space required by the magnetic member 140 because the electromagnetic heating device further includes other components.

Further, the coil disk assembly 100 further includes a groove 132 and a protrusion 134, and by providing the groove 132 on the bracket 130, it is possible to ensure reliability and accuracy of the assembly position of the coil winding 120.
