[0028] The utility model provides a coil disk assembly 100 with uniform heating.

[0029] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] In the embodiment of the present utility model, Figures 1 to 4As shown, the uniformly heated coil disk assembly 100 includes a disk frame 10, a coil 20 and a magnetic strip, wherein the two opposite sides of the disk frame 10 are respectively a first side and a second side, and the first side is provided with a plurality of magnetic strip grooves 13; the coil 20 is arranged on the second side, and the coil 20 is wound by a single wire to form a double-layer structure, and the two lead ends 21 of the coil 20 are both located on the same side; there are a plurality of magnetic strips and they are respectively arranged in a plurality of magnetic strip grooves 13.

[0031] It can be understood that the coil 20 is wound by a single wire, and can be wound from the outside to the inside first and then from the inside to the outside, or from the inside to the outside first and then from the outside to the inside. Regardless of the winding order, the two lead ends 21 are located on the same side, and the directions of the upper and lower layers of the coil 20 are consistent, that is, when power is turned on, the current directions of the upper and lower layers of the coil 20 are consistent, which is also clockwise or counterclockwise. Through the double-layer structure, the utility model has a larger magnetic field and high-efficiency heat energy conversion efficiency compared with the coil 20 with the same outer diameter, reduces the heat loss of the coil 20, and makes the coil 20 work more efficiently, stably and reliably.

[0032] The coil 20 of the utility model is formed and fixed by pre-winding. First, one end of the multiple magnetic lines of force is passed through the tensioner, and then passed around the clamp and fixed on the wire storage wheel. The main shaft is driven by the motor to realize asynchronous rotation of the mold assembly and the wire storage wheel, and the magnetic lines of force are wound on the mold core. During the winding process, hot air is blown to the enameled wire to melt the glue layer on the surface of the enameled wire so that the enameled wire is self-adhering to form the coil 20.

[0033] The technical solution of the utility model includes a disk rack 10, a coil 20 and a magnetic strip. The coil 20 is wound by a single wire to form a double-layer structure. The two lead-out ends 21 of the coil 20 are located on the same side. Since the technical means of winding the double-layer coil 20 by the same wire is adopted, the technical problems of low conversion efficiency, uneven heating and complex lead-out terminal fixing structure existing in the prior art using a single-layer coil are effectively solved, thereby achieving the technical effect of simple structure, convenient wiring and improved electromagnetic heating efficiency.

[0034] In the embodiment of the present utility model, Figures 1 to 3 As shown, the first layer of the coil 20 is wound from the outside to the inside, and the second layer of the coil 20 is wound from the inside to the outside, and the two lead ends 21 of the coil 20 are both located on the outside. The utility model adopts this winding method, so that the two lead ends 21 are located on the outside, which facilitates the electrical connection between the coil 20 and the controller. Through this winding method, the coil 20 is α-shaped, so this winding method is also called the alpha winding method. The alpha winding method can improve the efficiency of power conversion, reduce the heat loss of the coil 20, keep the coil 20 in a more stable working state, and reduce interference and toggling.

[0035] In the embodiment of the present utility model, Figures 1 to 3 As shown, two limit hooks 11 are provided on the outer side of the disc rack 10, and the two lead-out ends 21 of the coil 20 are respectively limited by the two limit hooks 11. The limit hooks 11 are in the shape of a hook and are integrally injection-molded with the coil 20.

[0036] In the embodiment of the present utility model, Figure 1 , Figure 3 and Figure 4 As shown, an annular boss 12 is provided in the middle of the second side, and the coil 20 is positioned by the boss 12. The coil 20 of the utility model is formed into a ring shape by winding, and when assembled with the disc rack 10, the center hole of the coil 20 is positioned by the boss 12, thereby improving the assembly accuracy and the efficiency of electromagnetic heating.

[0037] In the embodiment of the present utility model, Figure 1 , Figure 3 and Figure 4 As shown, the uniformly heated coil disk assembly 100 further includes a magnetic isolation sheet 40, which is disposed in the middle of the boss 12. The shape of the magnetic isolation sheet 40 is adapted to the internal shape of the boss 12, and is fixed to the bottom of the boss 12 by high temperature glue.

[0038] In the embodiment of the present utility model, Figure 2 and Figure 3 As shown, the magnetic strips are radially arranged on the first side. The radial distribution can increase the induction area and improve the efficiency of electromagnetic heating.

[0039] In the embodiment of the present utility model, Figure 2 and Figure 3 As shown, the magnetic stripes include a first magnetic stripe 31 and a second magnetic stripe 32. The length of the first magnetic stripe 31 is greater than that of the second magnetic stripe 32. The first magnetic stripe 31 and the second magnetic stripe 32 are arranged in an alternating manner. A plurality of first magnetic stripes 31 with a longer length are distributed in a radial manner, and a second magnetic stripe 32 with a shorter length is arranged between two adjacent first magnetic stripes 31 to fill the gap. The plurality of second magnetic stripes 32 are also distributed in a radial manner. The alternating manner can make the distribution of the magnetic stripes more compact and increase the sensing area.

[0040] In the embodiment of the present utility model, Figure 1 , Figure 3 and Figure 4 As shown, the uniformly heated coil disk assembly 100 further includes a high temperature soft glue 50, and the coil 20 is arranged on the disk frame 10 through the high temperature soft glue 50. Both sides of the high temperature soft glue 50 are sticky, the bottom of the high temperature soft glue 50 is bonded to the disk frame 10, and the coil 20 is bonded to the top of the high temperature soft glue 50.

[0041] In the embodiment of the present utility model, Figure 1, Figure 3 and Figure 4 As shown, the uniformly heated coil disk assembly 100 further includes heat insulating cotton 60, which is arranged on a side of the coil 20 away from the disk frame 10. The heat insulating cotton 60 is arranged on the top of the coil 20 by means of adhesive.

All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present invention.
