Background technique

In the existing induction cooker, the internal coil disk includes enameled wire, bracket and magnetic strip. In order to realize multi-layer winding, the winding compartment on the bracket is usually designed to be very high, and the winding groove formed is deep and narrow. As a result, the excessively high and thin plastic winding interlayers are insufficient in strength and prone to breakage; at the same time, due to the uniform height of each winding interlayer, when the number of enameled wire layers in the winding groove is small, the enameled wire is far away from the heating pot. The distance is relatively long, resulting in magnetic leakage and reducing the heating efficiency of the induction cooker.

In order to make the technical solution of the utility model clearer and clearer, it will be further described in detail below in conjunction with the accompanying drawings.

Detailed ways

The solution of the embodiment of the utility model is mainly: set the thickness of the coil winding interlayer to be inconsistent, improve the strength of the winding interlayer, and perform multi-layer winding when the winding groove is deep, which can also effectively prevent the winding The interlayer is broken to solve the contradiction between the too high depth of the winding groove and the too small thickness of the winding interlayer, effectively preventing magnetic flux leakage and improving the heating efficiency of the induction cooker.

Please refer to Fig. 1, Fig. 2 and Fig. 3, Fig. 1 is a three-dimensional structure diagram of a preferred embodiment of a coil disc without a coil of the present invention; Fig. 2 is a side view sectional view of a preferred embodiment of a coil disc of the present invention; Fig. 3 is a partially enlarged schematic view of the right side of the coil disk in Fig. 2 .

As shown in Fig. 1 and Fig. 2, a kind of coil disc proposed in this embodiment includes enameled wire 1, support 2 and six magnetic strips 3, and the six magnetic strips 3 are radially installed on the support 2 from the center of the coil disc. At the bottom of the upper surface of the bracket 2 corresponding to the position of each magnetic strip 3, several winding spacers 4 are arranged, and the adjacent winding spacers 4 form a winding groove 5, and the enameled wire 1 is wound on the winding In the wire slot 5 , the plurality of winding spacers 4 at least include a first winding spacer 41 and a second winding spacer 42 with different thicknesses. That is to say, the thicknesses of the winding spacers 4 in this embodiment may be inconsistent.

Specifically, as shown in FIG. 2 , in this embodiment, on each magnetic strip 3 , there are first winding spacers 41 and second winding spacers distributed along the length direction of the magnetic strip 3 (that is, the radial direction of the coil disk). Two winding spacers 42, wherein the first winding spacer 41 is close to the center of the coil disk, and the second winding spacer 42 is located outside the first winding spacer 41, ie away from the center of the coil disk.

As shown in Figure 3, two adjacent first winding spacers 41 form a first winding groove 51, and two adjacent second winding spacers 42 or the second winding spacer 42 and its adjacent first The winding spacer 41 forms a second winding slot 52 .

As a preferred embodiment, the thickness of the first winding spacer 41 is greater than the thickness of the second winding spacer 42, and the thickness of the first winding spacer 41 is 1.2-2% of the thickness of the second winding spacer 42. 3 times, preferably 1.3 times.

Thus, the strength of the winding spacer 4 can be improved by arranging the winding spacer 4 with different thicknesses, and the breakage of the winding spacer 4 can be effectively prevented when multi-layer winding is performed in the winding groove 5 .

Further, the above-mentioned first winding spacers 41 and the second winding spacers 42 can also be arranged in a staggered manner, for example, on the same magnetic strip 3, along the length direction of the magnetic strip 3, the first The winding spacer 41 and the second winding spacer 42; or, on the six magnetic strips 3 of the coil disk, the first winding spacer 41 is arranged on one of the magnetic strips 3 or a plurality of magnetic strips 3, and the other A second winding spacer 42 is arranged on a magnetic strip 3 or another plurality of magnetic strips 3. Through the staggered distribution of the first winding spacer 41 and the second winding spacer 42, the winding spacer is further improved. 4 strength.

In order to meet the needs of different winding layers, the height of the first winding spacer 41 is set to be greater than the height of the second winding spacer 42, and the first winding spacer 41 is higher than the height of the second winding spacer 42. The height can be an integer multiple of the diameter of the enameled wire 1, so that the number of layers of enameled wire 1 wound in the first winding slot 51 is 1-6 times the number of layers of enameled wire 1 wound in the second winding slot 52. In this way, for enameled wires 1 with the same cross-sectional area, when the number of layers of enameled wire 1 wound in the first winding groove 51 is greater than the number of layers of enameled wire 1 wound in the second winding groove 52, it can also ensure that the upper surface of all enameled wires 1 Being flush means that the distances between the upper surfaces of all the enameled wires 1 and the pot are equal, thereby effectively preventing magnetic leakage and increasing the magnetic induction.

That is to say, because the heights of the two kinds of winding spacers 4 are different, the depths of the correspondingly formed winding grooves 5 are inconsistent, so that the first winding groove 51 can adopt a multi-layer winding method, and the first winding groove 51 can adopt a multi-layer winding method. The second winding slot 52 may adopt a few-layer winding method. And because the thickness of the first winding spacer 41 is greater than the thickness of the second winding spacer 42, thus, can prevent the higher first winding spacer 41 strength from being too small and fracture, thereby solving the problem of the winding groove 5. The depth is too high and the thickness of the winding spacer 4 is too small.

As shown in Figure 2, in the present embodiment, the first winding spacer 41 corresponds to the first winding groove 51 of the deeper inner three turns to wind the three-layer enameled wire 1, and the remaining shallower outer winding grooves (that is, the first winding groove) Two layers of enameled wires 1 are wound in the second winding groove 52), and the heights of all the enameled wires 1 on the coil plate are basically the same, so that the distance between the enameled wires 1 of two different layers and the heating pan is the same, effectively preventing magnetic leakage and improving the efficiency of the induction cooker. thermal efficiency.

In addition, in another embodiment, the width of the first winding slot 51 and the second winding slot 52 may also be set to be different. For example, the width of the first winding groove 51 is set to be 1.2-6 times the width of the second winding groove 52 . In this way, the first winding slot 51 and the second winding slot 52 can wind enameled wires 1 with different cross-sectional areas, for example, the cross-sectional area of the enameled wire 1 in the first winding slot 51 can be larger than that of the enameled wire in the second winding slot 52 1 cross-sectional area. In order to meet different needs.

The utility model also proposes an electromagnetic cooker, which includes the coil disk described in the above-mentioned embodiment, wherein, the structural features of the coil disk refer to the above-mentioned embodiment, and will not be repeated here.

The coil disk and the electromagnetic oven of the embodiment of the utility model, by setting the thickness of the coil winding spacer to be inconsistent, can improve the strength of the winding spacer, and can effectively prevent winding when multi-layer winding is performed in a deep winding groove. The wire interlayer is broken, and at the same time, it can effectively prevent magnetic flux leakage, improve the heating efficiency of the induction cooker, and the coil disk of the utility model has a compact structure.
