In an implementation, the inner loop coil 21 and the outer loop coil 22 are connected in parallel, and the lead wire 40 includes an inner loop incoming wire 41 and an inner loop outgoing wire 42 connected to the inner loop coil 21, and an outer loop incoming wire 43 and an outer loop outgoing wire 44 connected to the outer loop coil 22; the inner ring incoming line 41 and the outer ring incoming line 43 are combined to form an incoming line, and the inner ring outgoing line 42 and the outer ring outgoing line 44 are combined to form an outgoing line. It should be noted that, when the coil panel 100 operates, the parallel connection of the inner ring coil 21 and the outer ring coil 22 can achieve the simultaneous control of the two, and when one of the two fails, the other will continue to operate, thereby ensuring the stability of the operation of the coil panel 100.

As another realizable embodiment, the inner loop coil 21 and the outer loop coil 22 are connected in series, and the lead wire 40 includes an incoming wire connected inside the inner loop coil 21, an outgoing wire connected outside the outer loop coil 22, and a connecting wire connected between the inner loop coil 21 and the outer loop coil 22.

In practical use, a user may select the connection manner of the inner loop coil 21 and the outer loop coil 22 of the coil set 20 within the above range according to needs, which is not limited in this embodiment.

Referring to fig. 6 and 8, in the present embodiment, a spacing region is formed between adjacent brackets, the spacing region is located between the outer edge of the inner ring receiving groove 111 and the inner edge of the outer ring receiving groove 121, at least one boss 13 is disposed on the bracket set 10 in the spacing region, and the upper surface of the boss 13 is higher than or flush with the upper surface of the coil set 20.

It should be noted that the boss 13 is located on the side of the coil support close to the coil assembly 20, so that when the coil assembly 20 is wound on the coil support, the boss 13 can be used to limit the installation position of the coil assembly 20 and the offset process of the coil assembly 20 on the coil support, thereby increasing the installation stability of the coil assembly 20 on the coil support. The boss 13 of the present embodiment may be formed by bending at least a portion of the support in the support set 10, and as an achievable implementation, at least a portion of the inner ring support 11 or at least a portion of the outer ring support 12 is bent toward the coil set 20 and forms at least one bent portion, and the bent portion forms the boss 13 toward the coil set 20.

Compare in original planar structure's coil brace, the coil brace that has the kink of this embodiment is when receiving external force extrusion or tractive, and when the stress that forms was transmitted in the coil brace, the kink can effectively slow down stress transmission rate to increase the transmission route of stress, thereby play the effect that hinders stress transmission to a certain extent, consequently can effectively avoid the deformation problem that stress arouses, increase coil brace's mechanical strength.

Further, the bending part is provided with a groove at one side departing from the coil assembly 20, and the groove is of a hollow structure, so that the overall weight of the coil support can be effectively reduced. The coil groups 20 may be respectively disposed on two opposite sides of the boss 13 along the radial direction of the coil disk 100, and the coil is not wound at the boss 13 position.

Referring to fig. 6, the boss 13 has at least one avoidance area 131, the avoidance area 131 communicates with two coil sets 20 adjacent to the boss 13, and at least part of the lead wire 40 passes through the avoidance area 131. The lead wire 40 passes through the avoiding region 131, so that the lead wire 40 can be prevented from being stacked above the boss 13, the wiring difficulty of the lead wire 40 is reduced, and the thickness of the coil panel 100 is increased when the lead wire 40 is arranged above the boss 13, thereby being beneficial to manufacturing the thin electromagnetic cooking device 200.
