When the conventional electromagnetic heating coil panel (i.e., coil structure) works, there are the following problems:

1. only the position covered by the bottom of the pan can be projected by the heating coil, and the position of the pan wall beyond the coil panel (coil panel winding area) cannot be heated (the heating effect is poor and even cannot be heated due to the increase of the panel spacing);

2. the phenomenon that the bottom is easy to be stuck in the frying process can be caused by the fact that the heating is too concentrated in the center;

3. In the process of heating the pot, the pot wall cannot be directly heated and is heated only by conduction of heat of the pot bottom, so that the temperature of the pot wall is low, residual water on the pot wall is difficult to evaporate, and splashing oil is easily caused when the water falls into hot oil in the cooking process;

4. The wall of the pot is not directly heated, the temperature of the area is lower, no pot gas is generated during cooking, and the fried dishes are unpaid.

The present utility model is directed to the above-mentioned technical problems, and the present utility model is considered to be improved by winding the electromagnetic heating coil, referring to fig. 5 to 7 and 9, the coil structure includes at least one coil unit, the coil unit has a plurality of turns of coils, each turn of the coil includes a first wire segment and a second wire segment which are connected to each other and have opposite currents, wherein the plurality of first wire segments are respectively arranged as working side wire segments, the plurality of working side wire segments are distributed along a first area to jointly form a working side wire set, one side of the working side wire set is used for corresponding to a piece to be heated, and is called a working side, for electromagnetic heating of the piece to be heated, at least part of the second wire segments are arranged as offset side wire segments, the offset side wire segments are arranged offset from the first area, the plurality of working side wire segments define a working area when working, the working side of the working side line group is arranged corresponding to a piece to be heated, each working side wire section is electrified with alternating current, the magnetic induction generated by each working side wire section extends towards the working side of the working side line group in the middle area of the working area under the ampere rule, the magnetic induction generated by each working side wire section extends towards the working side of the working side line group in the two side end areas of the working side along the direction of the working side away from the working side line group from one side end of the working area and then extends towards the other side end of the working area to form a closed magnetic field, so that the magnetic field formed by the working side line group extends towards the periphery of the outer side end area of the working side line group on one side to have a wider magnetic field area and extends towards the outer side of the working side line group to have a higher magnetic field distribution area, therefore, when the to-be-heated piece is heated, the bottom of the to-be-heated piece can be in a wider area, and the to-be-heated piece can extend to the side wall of the cooker so as to heat the side part of the cooker.

And among the plurality of coil units, the current directions of the working side wire segments of at least one pair of adjacent coil units are the same, so that the directions of the magnetic induction wires at the junctions of the adjacent coil units are opposite, and the magnetic induction wires can be mutually offset, thereby avoiding the problem of concentrated heating caused by the formation of a strong magnetic field region. And the peripheral dashed box in fig. 6 is the edge of the thermal field region of the coil structure.

The utility model mainly aims at forming a plurality of installation areas which are used for installing a coil structure and are distributed along the circumferential direction of a coil on the working side of the coil (refer to fig. 4 to 7), although under the condition of winding, each group of wires of the winding are parallel to each other and have the same current direction, so that each group of wires can generate a magnetic field which is perpendicular to the working surface of the coil assembly, the magnetic field is distributed in a vertical plane, and therefore, a stronger heating effect can be generated on the side wall of a pot arranged above the working surface of the coil assembly, on one hand, the winding can not completely cover the heating surface of the coil assembly due to the existence of a corner area of the coil structure, no winding exists in a certain area in the middle of the coil, and a stronger magnetic field can not be generated, and on the other hand, the magnetic fields of two adjacent groups of windings corresponding to the installation areas are mutually weakened in opposite current directions in the corner area, so that the magnetic field of the middle area of the double-sided coil is weaker, the magnetic field of the edge area is stronger, the magnetic field is unevenly distributed on the working surface of the coil assembly, the uniformity of heating is influenced, and how the coupling inductance of the electromagnetic coil and the pot bottom is more uniform is heated, and the design is further more uniform.

Referring to fig. 4 to 8, the bracket 10 includes a body 1, the body 1 having a first side and a second side disposed opposite to each other, the body 1 having at least two mounting areas 1a, the at least two mounting areas 1a being distributed along a circumferential direction of the body 1, the first side and the second side of the mounting areas 1a being configured to be mounted in correspondence with a coil structure 20 for heating a member to be heated disposed on the first side of the body 1; wherein the first side of each mounting area 1a is near the middle of the body 1, and protrudes from the first side of the mounting area 1a near the periphery of the body 1.

It should be noted that, referring to fig. 4 to 6, the coil structure 20 includes a plurality of coil units installed corresponding to the plurality of installation areas 1a, the coil units include a plurality of first wire segments arranged side by side at intervals, the middle of each first wire segment is bent towards the middle area of the body 1, and the current directions of at least one pair of adjacent working side wire segments of the coil units are opposite, so that the directions of magnetic induction wires at the junctions of the adjacent coil units are the same, and the adjacent coil units can be mutually overlapped to form a magnetic field intensity area, so that heating concentration at a specific position can be realized. However, this arrangement causes a problem that a blank area is formed in a region where the central portions of the plurality of coil units are close to each other, and in this region, electronic components such as a temperature sensor may be provided, and in the corner region, the directions of current are opposite, and the directions of magnetic fields are also opposite, so that the magnetic fields are weakened, and the coil structure 20 corresponding to the central portion of the body 1 generates a weak magnetic field.

In the technical solution provided by the present utility model, the bracket 10 includes a body 1, the body 1 has a first side and a second side that are oppositely disposed, the body 1 has at least two mounting areas 1a, the at least two mounting areas 1a are distributed along the circumferential direction of the body 1, and the first side and the second side of the mounting areas 1a are used for mounting corresponding to a coil structure 20 for heating a to-be-heated element 200 disposed on the first side of the body 1; the first side of each installation area 1a is arranged near the middle of the body 1, and the first side of the installation area 1a is protruded to be near the periphery of the body 1, so that the magnetic field generated by the coil structure 20 installed on the first side of the installation area 1a near the middle of the body 1 is closer to the to-be-heated piece 200 arranged on the first side of the body 1, the coupling inductance of the alternating magnetic field acting on the to-be-heated piece 200 and the pan bottom is enhanced after the coil structure 20 in the area is electrified, and the magnetic field strength is also enhanced, therefore, the magnetic field strength distribution of the whole heating surface is more uniform, and the heating effect is also more uniform, so that the problems that the coupling inductance strength distribution of the magnetic field and the pan on the wire coil working surface is uneven, and the heating uniformity is affected are solved.

In the first embodiment, referring to fig. 4 and 8, the first side of each mounting area 1a is inclined from a position near the middle of the body 1 toward the periphery of the first side of the mounting area 1a near the body 1 to a second side near the body 1. The arrangement is such that the surfaces of the installation areas 1a corresponding to the body 1 may be regarded as conical surfaces, so that the coil structures 20 arranged in the installation areas 1a are gradually arranged close to the to-be-heated member 200 from the periphery of the body 1 towards the middle of the body 1, so as to reduce the difference between the alternating magnetic field intensity acting on the to-be-heated member 200 and the coupling inductance of the pan bottom.

It will be appreciated that when a plurality of the mounting areas 1a are distributed over the first side of the body 1, the coil structure 20 is laid over the first side of the body 1, and the thickness of the body 1 at the central position is greater than the thickness of the periphery of the body 1. Of course, in other embodiments, a plurality of the mounting areas 1a may be located at an intermediate position between the middle and the periphery of the body 1. The first side of the body 1 may form a conical surface corresponding to a plurality of local areas of the mounting area 1a, and of course, the entire surface of the first side of the body 1 may be configured as a conical surface, and of course, the body 1 may also be configured in other possible shapes, which may be specifically determined according to practical situations, and the embodiment of the present disclosure is not limited thereto.

In the second embodiment, referring to fig. 10 and 11, since the wire segments of the coil structure 20 are arranged in such a way that the magnetic field in the middle area is only weak, in order to make the area of enhancing the magnetic field strength more targeted, at least one first side of the mounting area 1a is provided with a mounting protrusion 11 protruding at a position close to the middle of the body 1. In this way, the conical surface is not formed on the first side of the body 1 in a large area, but the mounting protrusion 11 is only disposed in a central local area of the body 1, so that the part of the coil structure 20 mounted on the mounting protrusion 11 can be closer to the member to be heated 200, so as to save the material cost and the production cost of the bracket 10. It will be appreciated that the mounting boss 11 is disposed with respect to the portion of the coil structure 20 where the magnetic field is weaker, so as to ensure that the portion of the coil structure where the magnetic field strength is weaker can be disposed substantially closer to the workpiece 200.

Specifically, in the present embodiment, the cross-sectional area of the mounting boss 11 is S1, and the cross-sectional area of the body 1 is S2, wherein 1/3.ltoreq.S1/S2.ltoreq.2/3. In this way, the area of the region where the magnetic field is relatively weak is ensured to be sufficiently arranged closer to the workpiece 200 to be heated, and the manufacturing cost of the bracket 10 is also considered. When the ratio of S1/S2 is too large or too small, the corresponding relation of the areas with weak magnetic fields is relatively poor, and the aim of improving the strength of the magnetic fields in a targeted manner is difficult to achieve.

Further, in the second embodiment, the mounting boss 11 has a plurality of side wall surfaces 111 facing a corresponding plurality of the mounting areas 1a, each of the side wall surfaces 111 being inclined from the bottom of the mounting boss 11 toward the top toward the first side away from the mounting area 1a near the periphery of the body 1. In this way, the tapered surfaces formed by the plurality of side wall surfaces 111 gradually transition to the highest point, so that the magnetic field acting on the bottom of the workpiece 200 by the partial coil structure 20 at the top of the mounting protrusion 11 is avoided, and the magnetic field acting on the bottom of the workpiece 200 by the partial coil structure 20 at the bottom circumference side of the mounting protrusion 11 increases as compared with the magnetic field, so that the overall magnetic field distribution is uneven.

Specifically, in the present embodiment, the height difference between the first side of each of the mounting areas 1a at a position near the middle of the body 1 and the position of the first side of the mounting area 1a near the periphery of the body 1 is H, wherein 1 mm.ltoreq.h.ltoreq.10mm. It can be understood that when the value of H is too small, the improvement effect is not obvious, and when the value of H is too large, the difference between the magnetic field intensity in the middle and the magnetic field intensity in the periphery is too large. The range value of H is restricted between 1mm and 10mm, so that the magnetic field intensity of the middle area can be enhanced, the magnetic field intensity distribution of the heating surface is more uniform, the heating effect of the coil structure 20 on the heating piece 200 is more uniform, and the phenomenon that the middle temperature of the heating piece 200 is too low in the cooking process and the cooking experience is influenced is avoided.

Specifically, in the present embodiment, a first side of each of the mounting areas 1a is provided with a first winding structure and a second winding structure, the first winding structure defining a first winding slot a, and the second winding structure defining a second winding slot b. In this way, the wires are placed in the winding slots so that they can be limited between the side walls of the winding slots, it being understood that the winding slots may be equally positioned so as to correspond to a high central area of the body 1 and a low peripheral area of the body 1, i.e. the bottom wall of the winding slots determines the distance between the coil structure 20 and the piece 200 to be heated.

Further, in the present embodiment, the stand 10 includes a body 1, the body 1 having a first side and a second side disposed opposite to each other, the body 1 having at least two mounting areas 1a, the at least two mounting areas 1a being distributed along a circumferential direction of the body 1, the first side and the second side of the mounting areas 1a being mounted to correspond to a coil structure 20 to be heated by a member 200 to be heated disposed at the first side of the body 1; wherein, the first side of each installation area 1a is near the middle of the body 1, and protrudes the first side of the installation area 1a near the periphery of the body 1, and the working side line group 21 is laid on the first side of the installation area 1 a. Since the working side line group 21 is laid on the first side of the installation area 1a, the distance of the working side line group 21 in the direction approaching and separating from the member to be heated 200 depends on the shape of the first side of the body 1, and when the first side of the body 1 is provided with a relief surface, the working side line group 21 of the coil structure 20 also fluctuates accordingly, thereby adjusting the position of the coil structure 20.
