Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work all belong to the protection scope of the present invention.

Referring to fig. 1 and 2, fig. 1 is a schematic top view of a coil panel assembly according to an embodiment of the present invention, and fig. 2 is a schematic side view of the coil panel assembly according to the embodiment of the present invention. An embodiment of the present invention provides a coil panel assembly 100. The coil panel assembly 100 includes a coil 110, a coil support 120, an air blowing device 130, and a magnetic strip support 140. The coil 110 is wound around the coil support 120. The air blowing device 130 is disposed adjacent to the coil support 120 and serves to provide a heat dissipating air flow to the coil 110 and the coil support 120. A plurality of magnetic stripe brackets 140 are fixed to the coil bracket 120 at intervals in the circumferential direction of the coil bracket 120. A connecting line between a central point of the air outlet of the air supply device 130 and a central point of the coil support 120 is a center dividing line 132, and the two magnetic stripe supports 140 close to the air supply device 130 are arranged in axial symmetry by taking the center dividing line 132 as a symmetry axis.

Specifically, the coil support may have an axisymmetrical structure, and the center parting line 132 is directed toward the central axis of the coil support 120 and is aligned with the central axis of the coil support 120. In the present embodiment, the plurality of magnetic stripe holders 140 includes at least three magnetic stripe holders 140, wherein two magnetic stripe holders 140 adjacent to the air blowing device 130 are disposed in axial symmetry with the central parting line 132 as a symmetry axis.

Because the two magnetic stripe brackets 140 close to the air supply device 130 are arranged in axial symmetry with the center parting line 132 of the air outlet of the air supply device 130 as a symmetry axis, a certain distance is kept between the two magnetic stripe brackets 140 close to the air supply device 130 and the air outlet of the air supply device 130, and then the heat dissipation airflow blown out from the air supply device 130 blows across the surfaces of the coil 110 and the coil bracket 120 in a certain distance without obstruction and relatively uniformly, so that the heat on the surface of the coil 110 can be taken away quickly when the surface of the coil 110 generates heat, the temperature of the coil 110 is reduced more effectively, and the safety of the coil panel assembly 100 is improved.

In the present embodiment, the included angle between the two magnetic stripe brackets 140 close to the air blowing device 130 is set to be equal to or larger than

Where n is the total number of magnetic stripe holders 140.

In a specific application, if the number of the magnetic stripe holders 140 is 3, the included angle between two magnetic stripe holders 140 close to the air blowing device 130 may be set to 120 °, and the included angles between three magnetic stripe holders 140 are 120 °.

In another specific application, if the number of the magnetic stripe holders 140 is 3, the included angle between the two magnetic stripe holders 140 close to the air supply device 130 may be set to 160 °, and the included angle between the two magnetic stripe holders 140 close to the air supply device 130 and the third magnetic stripe holder 140 is 100 °.

Through the above two application manners, it can be understood that when the included angles between the magnetic stripe brackets 140 are completely equal, the magnetic stripe brackets 140 are uniformly distributed, so that the mutual interaction between the magnetic stripes (not shown) on the magnetic stripe brackets 140 and the coils 110 is more uniform, and further, the heating effect of the coil panel assembly 100 is more uniform. When the included angle between the two magnetic stripe brackets 140 close to the air supply device 130 is larger, the obstruction of the heat dissipation airflow blown by the air supply device 130 is smaller, and the heat dissipation effect on the coil 110 is better. In practical application, the heat-radiating device can be selected according to the requirements of heating or heat radiation. However, for the purpose of improving the heat dissipation efficiency of the coil 110, the included angle between the two magnetic stripe brackets 140 close to the air supply device 130 is at least the included angle of all the magnetic stripe brackets 140 equally dividing the whole circumference.

In addition, because the two magnetic stripe brackets 140 close to the air supply device 130 are symmetrically arranged by taking the center parting line 132 as the symmetry axis, the heat dissipation air flow is blown out from the two ends of the coil bracket 120 along the directions a and B shown in fig. 1 after flowing out of the air supply device 130, and the distances from the heat dissipation air flow coming out from the two ends of the coil bracket 120 to the two magnetic stripe brackets 140 close to the air supply device 130 are equal, so that the resistance force exerted on the heat dissipation air flow coming out from the two ends of the coil bracket 120 is equal, and the heat dissipation effect of the air supply device 130 on the coil 110 is more uniform.

Alternatively, the other magnetic stripe holders 140 except the two magnetic stripe holders 140 close to the air blowing device 130 may be disposed in axial symmetry with the central dividing line 132 as a symmetry axis, or the other magnetic stripe holders 140 may be disposed in an asymmetric distribution.

Specifically, the coil holder 120 is divided into a first area 1200 close to the air blowing device and a second area 1202 far from the air blowing device, with the two magnetic stripe holders 140 close to the air blowing device 130 as boundaries. No magnetic strip support 140 is provided in the first region 1200. In the second region 1202, the rest of the magnetic stripe brackets 140 are symmetrically arranged by taking the middle line as a symmetry axis; or the rest of the magnet strip support 140 in the second region 1202 is asymmetrically arranged. And the angle between the remaining magnet bar supports 140 in the second region 1202 may be equally or unequally divided. In practical application, the distribution mode of the rest magnetic stripe supports 140 can be set according to what heating mode or heating effect the cooking appliance needs, and the embodiment of the present invention is not specifically limited. If the local part of the cooking utensil needs to be heated more effectively, the rest of the magnetic stripe supports 140 can be arranged in an asymmetric distribution mode so as to ensure the local heating effect of the cooking utensil; if the cooking utensil is required to be heated integrally and more uniformly, the rest of the magnetic stripe supports 140 can be arranged to be symmetrically distributed, the rest of the magnetic stripe supports 140 and the two magnetic stripe supports 140 close to the air supply device 130 are arranged in the second area 1202, and the included angle between every two magnetic stripe supports 140 can be equally divided, so that the integral uniform heating effect of the cooking utensil is guaranteed.

Optionally, the number of the magnetic stripe brackets 140 is an odd number not less than 3, wherein another magnetic stripe bracket 140 other than the two magnetic stripe brackets 140 close to the air supply device 130 is disposed on the other side of the coil bracket 120 opposite to the air supply device 130 along the extension line of the median line 132.

For example, in the present embodiment, as shown in fig. 1, the number of the magnetic stripe holders 140 is three, two of the magnetic stripe holders 140 are disposed near the air supply device 130, another magnetic stripe holder 140 is disposed on a side of the two magnetic stripe holders 140 away from the air supply device 130, and the magnetic stripe holders 140 are located on an extension line of the central line 132.

Alternatively, in another embodiment, the number of magnetic stripe holders 140 may also be five. In the three magnetic stripe supports 140 except for the two magnetic stripe supports 140 close to the air supply device 130, one magnetic stripe support 140 is disposed on one side of the two magnetic stripe supports 140 far away from the air supply device 130 and is located on the extension line of the middle division line 132, and the remaining two magnetic stripe supports 140 may be symmetrically or asymmetrically arranged according to a heating mode required by the cooking appliance. When the number of the magnetic stripe holders 140 is an odd number greater than 5, the arrangement of the magnetic stripe holders 140 will not be described herein. One of the magnetic strip supports 140 is disposed along the middle parting line 132 and away from the blowing device 130, so that the magnetic strip support 140 is disposed at the middle position of the entire coil panel assembly 100, and further the magnetic strip (not shown) on the magnetic strip support 140 changes the electromagnetic field shape of the coil 110 at the middle position of the entire coil panel assembly 100, so that more energy is concentrated on one side of the coil 110, and the heating effect at the middle position of the entire coil panel assembly 100 is improved.

The wind scooper 1304 can effectively guide the direction of the heat dissipation airflow, so that the heat dissipation airflow is blown out along the direction a and the direction B shown in fig. 1 and the direction C and the direction D shown in fig. 2, thereby achieving the uniform and rapid heat dissipation effect on the coil 110, improving the heat dissipation efficiency, and further improving the safety of the coil panel assembly 100.

In this embodiment, a threaded hole is formed in the coil bracket 120, a through hole is formed in the magnetic stripe bracket 140 at a position corresponding to the threaded hole, and the magnetic stripe bracket 140 is fixed to the coil bracket 120 by a screw, so as to improve the reliability of connection between the magnetic stripe bracket 140 and the coil bracket 120.

Or, in another embodiment, the magnetic stripe bracket 140 and the coil bracket 120 may be fixed by glue, so that each position on the magnetic stripe bracket 140 is connected with the coil bracket 120, thereby reducing the possibility of vibration of the magnetic stripe bracket 140 during use.

Alternatively, in another embodiment, the contact position between the magnetic stripe support 140 and the base of the coil support 120 may be melted into mushroom shape by using high temperature at the contact position between the magnetic stripe support 140 and the base of the coil support 120, and then the magnetic stripe support 140 is fixed on the coil support 120 after cooling, so as to improve the reliability of the connection between the magnetic stripe support 140 and the coil support 120 without modifying the coil support 120.

In this embodiment, no matter how the other magnetic stripe brackets 140 except the two magnetic stripe brackets 140 close to the air supply device 130 are arranged, the two magnetic stripe brackets 140 close to the air supply device 130 are symmetrically arranged with the central parting line 132 as a symmetry axis, so that the two magnetic stripe brackets 140 close to the air supply device 130 keep a certain distance from the air outlet of the air supply device 130, and further, the heat dissipation airflow more uniformly acts on the coil 110, so as to improve the heat dissipation effect and improve the reliability of the coil panel assembly 100.
