Fig. 11 is an exploded view of a coil panel according to an embodiment of the present invention.

Referring to fig. 1 to 11, the coil panel 100 provided in the present embodiment includes a coil support 10 and at least one coil set 20 wound on the coil support 10, and the coil set 20 includes at least two lead wires 30 led out from the coil set 20. At least part of the lead sections in the at least two leads 30 have the same routing path, at least another part of the at least two leads 30 has different routing paths, at least part of the lead sections with the same routing path are arranged in the same electrically insulated sleeve 40 in a penetrating manner, at least part of the lead sections with different routing paths are arranged in an electrically insulated extension tube in a penetrating manner, and the sleeve 40 and the extension tube are arranged in a split manner.

It should be noted that the coil panel 100 provided in the present embodiment may include a coil support 10 made of a magnetic conductive material and at least one coil set 20 wound. The coil support 10 and the coil panel 100 may be in a circular structure as shown in fig. 1 and 2, or may be in an oval or square structure according to the limitation of the installation space inside the electromagnetic cooking apparatus, which is not limited in this embodiment.

The coil support 10 may be made of at least partially or entirely magnetic conductive material, so as to form a magnetic portion of the coil support 10, and the magnetic portion may have a gathering and guiding function on the magnetic induction lines generated by the coil assembly 20, so that the magnetic induction lines act on the cookware above the coil panel 100. The magnetic part may be a plurality of magnetic strips 12 located between the coil support 10 and the coil assembly 20, i.e., the coil support 10 may include a support body 11 and a plurality of magnetic strips 12 disposed on the support body 11. The plurality of magnetic strips 12 are radially arranged on the bracket body 11 at the center of the coil bracket 10, the coil assembly 20 is wound on the bracket body 11 and the magnetic strips 12, the width and height of the magnetic strips 12 can be set according to the structure and requirement of the coil bracket 10, and the embodiment does not limit the configuration. A plurality of coil slots arranged in a spiral shape may be disposed on the coil support 10, and the coil assembly 20 may be wound according to the positions of the coil slots, so that the arrangement positions of the coil assembly 20 on the coil support 10 are effectively fixed by the coil slots.

The coil assembly 20 on the coil support 10 may be formed by winding an enameled wire bundle along the radial direction of the coil support 10, the enameled wire bundle is formed by winding or twisting a plurality of copper wires into a strand, and an insulator (generally, a paint skin) is coated outside the enameled wire bundle. Based on the coil support 10 wound with multiple layers of coil assemblies 20, the coil assemblies 20 are electrically connected with the power supply device through at least two leads 30, so that a large number of electrical signals are transmitted in the leads 30, and the enamel of the enameled wire harness itself is used to prevent the electrical contact or wear between adjacent leads 30 and between the leads 30 and the coil assemblies 20, which is not ideal in blocking effect, and is liable to cause the problem that the leads 30 often interfere or wear when the coil assemblies 20 transmit the electrical signals, even the phenomenon of electrical breakdown occurs, and seriously affects the stability and safety of the coil panel 100 in use. In contrast, in the present embodiment, the electrically insulated sleeve 40 and the extension pipe are sleeved outside the lead 30 of the coil assembly 20.

In one implementation, the sleeve 40 and/or extension tube may be a single layer tube, with the sleeve 40 and/or extension tube being a fiberglass tube or silicone tube. As another practical implementation, the sleeve 40 and/or the extension tube may be a double-layer tube, and the sleeve 40 and/or the extension tube includes a glass fiber tube and a silicone tube sleeved outside the glass fiber tube.

Wherein the thickness of the wall of the sleeve 40 and/or extension tube may range from 0.2 to 0.7 mm. When the wall thickness of the sleeve 40 and/or the extension pipe is too small, the electrical insulation performance of the sleeve 40 and/or the extension pipe is reduced, and the mechanical strength of the sleeve 40 and/or the extension pipe is affected, while the wall thickness of the sleeve 40 and/or the extension pipe is too large, the manufacturing cost of the coil panel 100 is increased, and the bending degree of the sleeve 40 and/or the extension pipe is reduced, so that the bending and routing process of the lead 30 cannot be adapted.

Further, referring to fig. 11, the sleeve 40 may be provided separately from the extension pipe, and the extension pipe may be respectively sleeved on different portions of the lead 30. Based on the lead wire 30 in the process of leading out the coil assembly 20, the arrangement mode is complex, the possibility that the whole lead wire 30 is completely sleeved with the whole sleeve 40 is low, branch lines exist at certain positions in the whole lead wire 30, the whole sleeve 40 cannot completely adapt to all branch lines of the lead wire 30 and routing paths at the branches of the branch lines, the whole sleeve 40 cannot be completely attached to the outside of the lead wire 30, the adaptation degree of the whole sleeve 40 and the whole lead wire 30 is low, the sleeve 40 cannot be used for protecting the lead wire 30, the sleeve 40 and the lead wire 30 are low in sleeving stability, and the sleeve 40 affects the routing paths of the lead wire 30. In this regard, the present embodiment divides at least two leads 30 into lead segments with the same routing path and lead segments with different routing paths, where the routing paths may include, but are not limited to, the extending direction of the leads 30 and the arrangement position of the leads 30. At least some of the lead segments with the same routing paths are disposed in the same sleeve 40, and at least some of the lead segments with different routing paths are disposed in at least two extension tubes. As an implementation manner, each of the lead segments with different routing paths may be sleeved with an extension tube, or partially sleeved with an extension tube, which is not limited in this embodiment. The extension tubes are respectively sleeved on the lead sections with different routing paths, so that the extension tubes can adapt to the lead sections with different routing paths at different positions, can be completely suitable for the routing paths at the bifurcation parts of the branch lines, and improves the adaptability of the sleeve 40 and the lead 30.

The sleeve 40 and the at least two extension tubes are arranged in a split manner, and due to the arrangement, when the lead 30 at different positions is sleeved by different extension tubes, the extension tubes are not limited by the traction of the adjacent extension tubes and the sleeve 40, so that the attaching degree of the extension tubes and the sleeve 40 outside the lead 30 is improved, and the protection effect of the sleeve 40 on the lead 30 is enhanced. For example, the bifurcation of the branch line may be disposed between adjacent extension tubes or the extension tube and the sleeve 40, thereby avoiding the influence of the extension tube on the lead 30 at the bifurcation. Further, based on the sleeve 40 is made of an electrically insulating material, it can not only protect the lead 30 from rubbing against an external electronic component or a structural member, thereby preventing the worn lead 30 from exposing the conductive wires, but also improve the effect of electrically insulating the lead 30 from the external electronic component, and ensure the stability of electrical signal transmission in the lead 30.

The coil assembly 20 may include at least two coils, each coil is led out by at least two lead wires 30, the portions of the at least two lead wires 30 having the same routing path are inserted into the same casing 40, and the portions of the at least two lead wires 30 having different routing paths are respectively inserted into the at least two extension tubes in a one-to-one correspondence manner.

It should be noted that the coil assembly 20 of the present embodiment may include at least two coils, and the at least two coils may be arranged in an inner and outer sleeve manner, or arranged in an up-down overlapping manner, or arranged in an array manner, and the specific arrangement manner of the coils is not limited in the present embodiment. At least two coils are disposed in the coil assembly 20, and different heating effects can be formed by using different coils. The specific operation mode is as follows: the actual heating temperature of each coil is regulated and controlled by respectively controlling the electric signal input of the coils, so that the coils at different positions can have different heating effects. For example, during the cooking process, the temperature near the center of the coil panel 100 is required to be higher, and the temperature near the edge of the coil panel is required to be lower, so that the current input to the coil near the center of the coil panel 100 can be increased, and the current input to the coil near the edge of the coil panel 100 can be reduced, thereby enriching the heating effect of the coil assembly 20 and meeting the user's requirements for different heating effects. The present embodiment does not limit the specific number of coils in the coil assembly 20.

Specifically, referring to fig. 1 to 4, the coil assembly 20 at least includes an inner coil 21 and an outer coil 22 sleeved with each other from the center of the coil panel 100 to the edge of the coil panel 100, and a spacing region 23 is provided between the outer edge of the inner coil 21 and the inner edge of the outer coil 22.

It should be noted that, in the current coil assembly 20, the coil panel 100 is tightly wound from the center position of the coil panel 100 to the edge position of the coil panel 100, and the magnetic fields generated by the coil panel 100 are overlapped at a position close to the middle point of the radius of the coil panel 100, so that the magnetic field strength at this position is much stronger than the center position and the edge position of the coil panel 100. Such a phenomenon causes the temperature of the central position and the edge position of the heated pot to be lower, and a low-temperature heating area is generated, so that the problem that food in the pot is often half-cooked is caused. However, the temperature near the midpoint of the radius is high, creating a heated high temperature zone, causing problems with the food therein often being burnt. In view of the above, in the present embodiment, the coil assembly 20 is disposed as the inner ring coil 21 and the outer ring coil 22 which are sleeved with each other, and a spacing region 23 is provided between the two, and no coil assembly 20 is disposed in the spacing region 23, when the magnetic fields generated by the inner ring coil 21 and the outer ring coil 22 are superposed in the spacing region 23, the magnetic field strength of the spacing region 23 and the magnetic field strength of the edge position of the coil panel 100 are substantially equal, so that there are no heating low temperature region and heating high temperature region in the heated pot, the heating uniformity of the whole pot is improved, the problem of food entrapment or pot pasting is avoided, and the heating effect of the electromagnetic cooking device with the coil panel 100 is improved. Further, the coil assembly 20 is not disposed in the spacing region 23, so that the number of turns of the coil assembly 20 can be effectively reduced, and the manufacturing cost of the coil panel 100 can be reduced.

Referring to FIG. 4, a central void area 24 is reserved in the center of the coil, the central void area 24 is not wound around the coil assembly 20, and the temperature measuring element can be disposed in a portion of the central void area 24. Wherein, the radius of the central vacant region 24 may be the portion shown by L1 in fig. 4, the length of the inner loop coil 21 may be the portion shown by L2 in the figure, the length of the spacing region 23 may be the portion shown by L3, and the length of the outer loop coil 22 may be the portion shown by L4. The radius of the coil disc 100 may be the portion shown at L0. As an achievable embodiment, the ratio of L1 to L0 may range from 14% to 34%, the ratio of L2 to L0 may range from 32% to 52%, the ratio of L3 to L0 may range from 5% to 25%, and the ratio of L4 to L0 may range from 9% to 29%.

Further, the inner ring coil 21 and the outer ring coil 22 may be connected in parallel with each other, and the lead 30 includes an inner ring incoming line 311 connected to the inner side of the inner ring coil 21 and an inner ring outgoing line 321 connected to the outer side of the inner ring coil 21, and an outer ring incoming line 312 connected to the inner side of the outer ring coil 22 and an outer ring outgoing line 322 connected to the outer side of the outer ring coil 22.

At least part of the inner ring incoming lines 311 and at least part of the outer ring incoming lines 312 merge to form the incoming lines 31 of the lead 30, and at least part of the inner ring outgoing lines 321 and at least part of the outer ring outgoing lines 322 merge to form the outgoing lines 32 of the lead 30.

It should be noted that, the inner ring coil 21 and the outer ring coil 22 are connected in parallel, electrical signals can be simultaneously input to the inner ring coil 21 and the outer ring coil 22 by using the incoming line 31, and output electrical signals of the inner ring coil 21 and the outer ring coil 22 are simultaneously received by using the outgoing line 32, so that the efficiency of the control operation of the coil panel 100 is improved.

Referring to fig. 11, the sleeve 40 of the present embodiment may include one or more of the following:

the inlet wire sleeve 41, the inlet wire sleeve 41 cover is established on inlet wire 31. Based on the embodiment, the inner ring incoming line 311 and the outer ring incoming line 312 converge and become the incoming line 31, and the incoming line sleeve 41 is sleeved outside the incoming line 31, so that the merged inner ring incoming line 311 and outer ring incoming line 312 can be protected at the same time. Compared with the arrangement mode that the sleeve pipes are sleeved on the inner ring inlet wire 311 and the outer ring inlet wire 312 respectively, the arrangement mode can reduce the number of the sleeve pipes on one hand, and the inner ring inlet wire 311 and the outer ring inlet wire 312 are sleeved by one sleeve pipe at the same time, so that the cost of the sleeve pipes is reduced; on the other hand, the inner loop incoming line 311 and the outer loop incoming line 312 can be electrically connected in the incoming line sleeve 41, so that the wiring difficulty of the two is reduced, and the installation efficiency of the sleeve 40 on the coil panel 100 is improved.

And the outgoing line sleeve 42 is sleeved on the outgoing line 32, and the outgoing line sleeve 42 is sleeved on the outgoing line 32. Similar to the incoming line 31, the inner ring outgoing line 321 and the outer ring outgoing line 322 of the present embodiment converge and form the outgoing line 32, and the outgoing line 32 is sleeved with the outgoing line bushing 42, so that the merged inner ring outgoing line 321 and outer ring outgoing line 322 can be protected at the same time, and compared with a configuration in which bushings are respectively sleeved on the inner ring outgoing line 321 and the outer ring outgoing line 322, such a configuration can also reduce the number of bushings and reduce the cost of the bushings on the one hand; on the other hand, the inner ring outgoing line 321 and the outer ring outgoing line 322 can be electrically connected in the outgoing line sleeve 42 conveniently, so that the wiring difficulty of the inner ring outgoing line 321 and the outer ring outgoing line 322 is reduced, and the installation efficiency of the sleeve 40 on the coil panel 100 is improved.

It should be noted that, based on the inner loop coil 21 being closer to the center of the coil panel 100 than the outer loop coil 22, the inner loop incoming line 311 of the inner loop coil 21 is led into the inner loop coil 21 from the position close to the center of the coil panel 100, and the outer loop incoming line 312 of the outer loop coil 22 is led into the outer loop coil 22 from the region between the center position and the edge position of the coil panel 100, so that the distance between the distribution positions of the inner loop incoming line 311 and the outer loop incoming line 312 on the coil panel 100 is larger. And a bifurcation of lead 30 exists between inner loop lead-in 311 and lead-in 31.

It should be noted that, based on that the outer ring coil 22 is closer to the edge position of the coil panel 100 than the inner ring coil 21, the outer ring outgoing line 322 of the outer ring coil 22 is led out from the edge position close to the coil panel 100, and the inner ring outgoing line 321 of the inner ring coil 21 is led out from the region between the center position and the edge position of the coil panel 100, so that the separation distance between the inner ring outgoing line 321 and the outer ring outgoing line 322 at the distribution positions on the coil panel 100 is larger. And a bifurcation of the lead wire 30 exists between the inner ring-out line 321 and the out line 32.

Moreover, the first incoming line extension tube 411 and the incoming line sleeve 41, and the first outgoing line extension tube 421 and the outgoing line sleeve 42 are respectively arranged to be abutted against each other, so that the lead 30 between the first incoming line extension tube 411 and the incoming line sleeve 41, or the lead 30 between the first outgoing line extension tube 421 and the outgoing line sleeve 42 can be prevented from being exposed outside in the using process, and being abraded due to friction with an external electronic element or a structural member, meanwhile, the problem that the abraded lead is exposed and short-circuited with the external electronic element is prevented, and the stability of electric signal transmission in the coil panel 100 is improved.
