That is, the central portion of the inner coil 220 is arranged in a plane (inner plane heating winding 221), and the edge portion of the inner coil 220 is arranged upward from the plane portion in an inclined plane (inner inclined plane heating winding 222). The inclination refers to the extending trend, so the specific implementation modes are various, such as plane inclination, cambered surface inclination, wavy surface inclination and the like. In the radial direction of the inner coil winding 220, the coil density of the inclined portion is greater than that of the planar portion.

Through extending inner inclined section 520 along inner inclined plane heating winding 222 arc for inner inclined section 520 not only provides sufficient magnetic field intensity for inner inclined plane heating winding 222, also keeps being equivalent to the distance between inner flat section 510 to inner flat heating winding 221, makes the heating effect of inner inclined plane heating winding 222 and inner flat heating winding 221 equivalent, is favorable to even heating.

In the winding process of the inner coil winding 220, the enameled wire is only clamped in the first inner winding gap 240. So that the enamel wire can be simply and reliably wound in the first inner winding gap 240. The windings in the first inner winding gap 240 are close-wound as an example.
In order to improve the heating efficiency of the inner heating area 200, fully and reasonably utilize the space, and reduce the area of the coil panel, the coil panel further includes a second inner limiting piece, one end of the second inner limiting piece is connected to the inner supporting structure 230 and is located above the first inner limiting piece 210, a second inner winding gap (not shown) is formed between the second inner limiting piece and the first inner limiting piece 210, and the inner coil winding 220 is disposed in the second inner winding gap (not shown).
Specifically, in the present embodiment, the shape of the second inner limiting piece is similar to the shape of the first inner limiting piece 210, and the second inner limiting piece also has a straight section and an arc-shaped section. The second inner limiting piece is arranged corresponding to the first inner limiting piece 210, so that a second inner limiting gap with a straight section and an arc section is formed between the second inner limiting piece and the first inner limiting piece 210.

The plurality of second inner limiting pieces are arranged along the circumferential direction of the inner support structure 230 and correspond to the first inner limiting pieces 210, so that the second inner limiting gaps are arranged in a circular ring along the circumferential direction of the inner support structure 230. In the winding process of the inner coil winding 220, the enameled wire is only clamped in the first inner winding gap 240 and the second winding gap. So that the enamel wire can be simply and reliably wound in the first and second inner winding gaps 240 and 240. The windings in the second inner winding gap (not shown) are tightly wound as an example. Through the setting of spacing piece in the second, formed double-deck coil structure (upper and lower two-layer is close-wound) in coil winding's middle part, be favorable to the heating efficiency of the interior zone of heating 200 of improving by a wide margin.
In order to improve the heating efficiency of the inner heating area 200 and to fully and reasonably utilize the space, and to simplify the processing technology of the coil panel, the coil panel further includes inner isolation ribs, and the inner isolation ribs are arranged along the length direction of the first inner limiting piece 210, so as to form a plurality of inner wire winding grooves arranged along the length direction of the first inner limiting piece 210 on the first inner limiting piece 210.
specifically, in this embodiment, the cross-section of the inner spacer rib may have various shapes, such as a triangle, a square, and other polygons. The inner isolation rib can extend along the width direction of the first inner limiting sheet 210, and the inner isolation rib extends in a concave arc manner, so that a plurality of inner isolation ribs can be enclosed to form a circular ring. The inner isolation ribs on the same first inner limiting piece 210 are arranged along the length direction of the first inner limiting piece 210, and the inner isolation ribs at the same position on adjacent first inner limiting pieces 210 are arranged along the circumferential direction of the inner support structure 230, so as to form an inner winding groove extending along the circumferential direction of the inner support structure 230. The number of coils that can coil in same interior wire winding inslot can set up as required, like 1 circle, 2 circles, 3 circles etc. all can. The inner coil winding 220 is formed by the inner winding slots to exemplify the open winding. The connection between the first inner limiting piece 210, the inner separating rib, and the inner supporting structure 230 may be detachable (by screws, fasteners, or adhesives), or may be integrally formed. Compared with the scheme of simultaneously arranging the first inner limiting piece 210 and the second inner limiting piece, the scheme of arranging the first inner limiting piece 210 and the inner isolation rib is easier to realize. Through the setting of interior isolation muscle, formed double-deck coil structure (the lower floor is close winding, the upper strata is sparse winding) in coil winding's middle part, be favorable to the heating efficiency of the interior zone of heating 200 of big width improvement.
In order to further improve the heating efficiency of the outer heating zone 300, an outer coil winding 330 is wound on the outer heating zone 300, the outer coil winding 330 has an outer plane heating winding 331 located in the middle of the outer heating zone 300, and an outer inclined plane heating winding 332 located at the edge and inclined upwards; the external magnetic stripe 400 includes an outer planar section 410 disposed corresponding to the outer planar heating winding 331, and an outer inclined section 420 disposed corresponding to the outer inclined heating winding.

That is, the central portion of the outer coil 330 is arranged in a plane (outer plane heating coil 331), and the edge portion of the outer coil 330 is arranged upward from the plane portion in an inclined plane (outer inclined plane heating coil 332). The inclination refers to the extending trend, so the specific implementation modes are various, such as plane inclination, cambered surface inclination, wavy surface inclination and the like. In the radial direction of the outer coil winding 330, the coil density of the inclined portion is greater than that of the planar portion. By arranging the external magnetic stripe 400 on the external inclined section 420 corresponding to the external inclined plane heating winding 332, the external inclined section 420 compensates the magnetic field intensity of the external inclined plane heating winding 332, so that the magnetic field intensity of the region where the external inclined plane heating winding 332 and the external plane heating winding 331 are located is equivalent, and uniform heating is facilitated. In addition, through the setting of outer inclined plane heating winding 332, when increasing outer zone of heating 300 edge heating efficiency for outer inclined plane heating winding 332 is closer apart from the pan, is favorable to the heating to the pan.
In addition, in order to improve the heating uniformity of the coil panel outer heating area 300, the width of the outer magnetic stripe 400 is gradually increased along the direction from the middle to the edge of the outer heating area 300. Along with the increase of outside magnetic stripe 400 width for magnetic field intensity also increases along with the extending direction of magnetic stripe, so, just compensate outer coil winding 330 to the area increase gradually, the great distance difference that has reduced between two adjacent outside magnetic stripes 400 for the middle part of the outer zone of heating 300 is comparable with peripheral heating efficiency.
