As shown in fig. 1 to 16, the present embodiment provides a coil panel, which includes a coil support 1 and a coil 2 located on the coil support 1, wherein a plurality of moving members 5 are disposed on the coil support 1, the plurality of moving members 5 are arranged at intervals along a circumferential direction of the coil support 1, a portion of the coil 2 corresponding to the moving members 5 is connected to the moving members 5, other portions of the coil 2 are suspended, and the moving members 5 can reciprocate between an edge and a center of the coil support 1 to drive a portion of the coil 2 connected to the moving members 5 to contract inward or expand outward.

The coil panel provided by the embodiment can be exemplarily applied to an electromagnetic oven, and the coil panel can be arranged in the electromagnetic oven and used for heating a pot on the electromagnetic oven by using an induced magnetic field generated by the coil panel when the coil panel is powered on.

Specifically, the coil panel can include coil support 1 and coil 2, coil 2 is located coil support 1 top, coil support 1 is used for supporting and fixing coil 2, after coil 2 circular telegram, there is the electric current to pass through in coil 2, coil 2 produces the planar alternating magnetic field of perpendicular to coil 2 place, this alternating magnetic field passes the pan of placing on the electromagnetism stove, and produce perpendicular to this alternating magnetic field at the pan bottom, the alternating induction vortex parallel with coil 2 promptly, this alternating induction vortex has the heating effect to the bottom of pan under the excitation of alternating magnetic field, thereby heat the food in pan and the pan.

Usually, the coil 2 is fixedly arranged on the coil disc, and because the coil 2 is usually in an approximate multilayer circular ring shape formed by winding from inside to outside, the alternating induced eddy current formed by the coil 2 in this form on the cooker is not uniformly distributed, especially for the center of the bottom of the cooker, the density of the induced eddy current is usually small, so the center of the bottom of the cooker forms a central cold zone, which can cause the coil 2 to heat the cooker non-uniformly.

In order to solve the above-described technical problem, the heating uniformity of the coil 2 is improved. As shown in fig. 1 to 12, in the present embodiment, a plurality of moving members 5 are further provided on the coil support 1, and the plurality of moving members 5 may be arranged at intervals in the circumferential direction of the coil support 1. Illustratively, the plurality of moving members 5 may be arranged at even intervals in the circumferential direction of the coil support 1. And, the moving member 5 can be reciprocally moved between the edge and the center of the coil support 1 to change the size of the coil 2 by the moving member 5, thereby improving the heating uniformity of the coil 2.

Specifically, the plurality of moving members 5 may be provided on the coil support 1, that is, the plurality of moving members 5 may be in the same spatial height range as the coil support 1, the coil 2 is located above the coil support 1, and the coil 2 may be fixed on the upper surface of the moving members 5. That is, the coil 2 and the plurality of moving parts 5 are fixed on the moving parts 5 at corresponding portions, and the rest of the coil 2 is suspended above the coil support 1.

Because the coil 2 is usually made of a material with good softness, the shape of the coil 2 can be changed easily under the action of external force, so that the part of the coil 2 fixed on the moving part 5 can be driven to move correspondingly in the moving process of the moving part 5.

For example, as shown in fig. 1 to 5, taking the edge of the moving part 5 on the coil support 1 as the initial position of the moving part 5 as an example, when the moving part 5 is at the initial position, the coil 2 may be in an original state, that is, the coil 2 is in a larger circular ring shape as a whole, at this time, the coil 2 is mainly concentrated between the outer part of the middle of the coil support 1 and the edge, and the magnetic field generated by the coil 2 is mainly concentrated in the above area, so that the heating effect of the outer area of the middle is better for the whole coil 2; the coil 2 does not effectively cover the part of the coil support 1 close to the center, so the density of the magnetic field generated by the center part of the coil support 1 is lower, and the coil 2 heats the corresponding part of the cooker corresponding to the part less.

As shown in fig. 8 to 12, in the process that the moving member 5 moves from the edge of the coil support 1 to the center of the coil support 1, the portion of the coil 2 fixed on the moving member 5 correspondingly moves along with the moving member 5, that is, the portion of the coil 2 corresponding to the moving member 5 also moves to the center of the coil support 1 synchronously, it can be understood that the portion of the coil 2 corresponding to the periphery of the moving member 5 is correspondingly driven to shift to the center of the coil support 1, so that the overall shape of the coil 2 changes, the coverage area of the coil 2 near the center of the coil support 1 increases, the strength of the magnetic field near the center of the coil 2 increases, and thus the heating efficiency of the center of the cooker increases.

Through the reciprocating motion of moving member 5, can drive the corresponding position reciprocating motion of coil 2, the size of coil 2 is corresponding can change like this, the concentrated region of coil 2 also changes, to coil 2 is whole, coil 2 changes in the density in each region, coil 2 changes concentrating on coil support 1 and leaning on the outer position and concentrating on coil support 1 and be close to between the central point, at the in-process that coil 2 removed along with moving member 5, coil 2 can be more even cover coil support 1 by each region of center to outer fringe, therefore the heating of coil 2 is more even, heating efficiency is higher.

Wherein, for the connection fixation of the corresponding part of the coil 2 and the moving member 5, optionally, the coil 2 can be adhered to the moving member 5. The part of the coil 2 corresponding to the moving member 5 is bonded to the moving member 5, so that the corresponding part of the coil 2 is connected with the moving member 5, and the moving member 5 drives the coil 2 to contract inwards or expand outwards. It can be understood that coil 2 can glue on moving member 5 through the great liquid glue of viscidity or solid glue etc. to ensure that coil 2 and moving member 5 firm in connection avoid driving the in-process that coil 2 removed at moving member 5, and coil 2 drops from moving member 5.

For the reciprocating movement of the moving member 5 between the edge and the center of the coil support 1, in a possible embodiment, a plurality of sliding rails 11 may be disposed on the coil support 1, the moving member 5 may be disposed in the sliding rails 11 and may move along the sliding rails 11, and the upper surface of the moving member 5 protrudes from the upper surface of the sliding rails 11.

Through set up slide rail 11 on coil support 1, slide rail 11 can extend between the center of coil support 1 to the edge, can set up moving member 5 like this in slide rail 11, and moving member 5 can move along slide rail 11, and then the position that is connected with moving member 5 of drive coil 2 is at coil support 1's edge and center between reciprocating motion.

In addition, because the position that coil 2 and moving member 5 correspond is connected with moving member 5, and other positions of coil 2 are unsettled in coil support 1 top, therefore the upper surface of moving member 5 can be protruded on the slide rail 11 surface, the whole place plane of coil 2 is higher than the space scope that coil support 1 is located, have the space between coil 2 and coil support 1 promptly, can guarantee like this that coil 2 and the position that moving member 5 corresponds are connected on moving member 5, and other positions of coil 2 can be unsettled in the top between coil 2, in the in-process that moving member 5 drove the corresponding position removal of coil 2, other positions of coil 2 can not disturb the removal of coil 2.

In one embodiment, the slide rail 11 may extend in a radial direction of the coil support 1, and the moving member 5 moves in the radial direction of the coil support 1 within the slide rail 11. By providing the slide rail 11 to extend in the radial direction of the coil support 1, the moving member 5 moves within the slide rail 11, and thus the moving member 5 moves toward the center of the coil support 1 or toward the edge of the coil support 1 in the radial direction of the coil support 1.

In the process that the moving piece 5 moves along the radial direction of the coil support 1, the corresponding part of the coil 2 connected to the moving piece 5 also moves along the radial direction of the moving piece 5 on the coil support 1, namely, the corresponding part of the coil 2 contracts or expands along the radial direction of the coil support 1, the size and the shape of the coil 2 are sequentially changed, the part of the coil support 1 corresponding to the coil 2 is changed, and the heating uniformity of the coil 2 is improved.

Alternatively, the slide rail 11 may not extend along the radial direction of the coil support 1, but the extending direction of the slide rail 11 and the radial direction of the coil support 1 form an included angle, and the slide rail 11 also extends from the center to the edge of the coil support 1, as long as the corresponding portion of the coil 2 can be inwardly contracted or outwardly expanded.

As shown in fig. 3 and 10, in order to realize the movement of the moving member 5 in the slide rail 11, the coil panel may further include a connecting rod 3, a first end 31 of the connecting rod 3 may rotate around the central axis of the coil support 1, and a second end 32 of the connecting rod 3 may be rotatably connected to the moving member 5 to drive the moving member 5 to move in the slide rail 11.

Like this when the first end 31 of connecting rod 3 rotates around the axis of coil support 1, because its second end 32 is connected with moving member 5, connecting rod 3 second end 32 only can follow slide rail 11 and move, therefore whole connecting rod 3 can twist reverse, through the rotation of its first end 31 around the axis of coil support 1, drives connecting rod 3 second end 32 and removes in slide rail 11, and then can drive moving member 5 and remove in slide rail 11.

Wherein, the first end 31 of connecting rod 3 can wind coil support 1 reciprocating rotation, and connecting rod 3 can rotate along clockwise and anticlockwise promptly to can drive moving member 5 reciprocating motion in slide rail 11, and then drive the corresponding position of coil 2 by moving member 5 and inwards contract or outwards expand, with the heating homogeneity and the heating efficiency that improve coil 2.

In this embodiment, the coil support 1 may have a central hole 14, the slide rail 11 may extend from an outer edge of the coil support 1 to an outside of the central hole 14, the central support 4 may be disposed in the central hole 14 of the coil support 1, and the central support 4 drives the first end 31 of the connecting rod 3 to rotate. Specifically, the central bracket 4 can rotate around its central axis, and the first end 31 of the connecting rod 3 can be driven to rotate around the center of the coil bracket 1 by rotatably connecting the first end 31 of the connecting rod 3 with the central bracket 4 in the rotating process of the central bracket 4. It will be appreciated that the central support 4 may be reciprocatingly rotatable in both a clockwise and a counter-clockwise direction, such that the first end 31 of the connecting rod 3 is reciprocatingly rotatable.

The rotation angle of the center frame 4 may range between-65 deg. during the reciprocal rotation of the center frame 4 in the clockwise direction and the counterclockwise direction. As shown in fig. 1 to 5, when the orientation of the links 3 is in the radial direction of the coil support 1, as shown in fig. 8 to 12, when the links 3 are twisted, an angle is formed with respect to the radial direction of the coil support 1.

In this embodiment, the angle of the reciprocal rotation of the central support 4 can be controlled within a certain range to match the distance of the movement of the moving member 5 along the slide rail 11 of the coil support 1 according to the specific dimensions of the coil support 1 and the moving member 5, for example, the rotation angle of the central support 4 can be in the range of-65 ° to 65 °.

For the rotational connection between the first end 31 of the connecting rod 3 and the central bracket 4, optionally, a plurality of connecting portions 41 extend from the outer wall surface of the central bracket 4 along the circumferential direction, the plurality of connecting portions 41 respectively correspond to the first ends 31 of the plurality of connecting rods 3, a connecting shaft 411 is disposed on the connecting portions 41, and the first end 31 of the connecting rod 3 is rotationally connected with the central bracket 4 through the connecting shaft 411.

By providing a plurality of connecting portions 41 on the outer wall surface of the center frame 4, the plurality of connecting portions 41 are spaced apart along the circumferential direction of the outer wall surface of the center frame 4, for example, when the center frame 4 is not rotated, each connecting portion 41 of the center frame 4 corresponds to each slide rail 11 of the coil frame 1, that is, each connecting portion 41 corresponds to the first end 31 of the link 3 below the slide rail 11. Each connecting portion 41 is provided with a connecting shaft 411, the first end 31 of the connecting rod 3 can be provided with a connecting hole 33, and when the connecting rod 3 is connected with the central bracket 4, the connecting hole 33 of the first end 31 of the connecting rod 3 is sleeved on the connecting shaft 411 of the connecting portion 41 of the central bracket 4, so that the first end 31 of the connecting rod 3 can be rotatably connected with the central bracket 4.

It should be noted that, in this embodiment, still be provided with the magnetic stripe on the coil panel, the magnetic stripe can be located the below of coil 2, and the magnetic stripe can include a plurality ofly, and a plurality of magnetic stripes can be arranged along the circumference interval of coil bracket 1. The magnetic strip mainly has the effects of changing the appearance of the electromagnetic field generated by the coil 2, reducing the electromagnetic field generated by the back of the coil 2 and concentrating more energy to the front of the coil 2, namely, enabling the magnetic field generated by the coil 2 to act on a cooker above the coil 2 more.

So on the one hand can improve the heating efficiency of coil 2 to the pan, on the other hand also can reduce coil 2 to the electromagnetic interference that devices such as circuit board below produced, guarantee the job stabilization nature of these devices. In this embodiment, the magnetic stripe may be located in the spatial range where the coil bracket 1 is located, or the magnetic stripe may also be located below the coil bracket 1, and it is only necessary to ensure that the magnetic stripe is located below the coil 2, and it is sufficient to guide the magnetic field generated by the coil 2 to the front of the coil 2, which is not specifically limited in this embodiment.

In order to rationalize the layout structure of the coil panel, the moving member 5 may be a magnetic strip in one embodiment, on the basis that the components of the coil panel are not too tightly or cannot be arranged due to the introduction of redundant components. That is, the moving member 5 located in the slide rail 11 on the coil support 1 is a magnetic stripe so that the magnetic stripe can move between the center to the edge of the coil support 1 along the slide rail 11.
