Below with reference to Fig. 1-Fig. 3, describe according to the coil panel 100 of the utility model embodiment.Coil panel 100 can be used for electromagnetic oven.As shown in Figure 1-Figure 3, according to the coil panel 100 of the utility model embodiment, comprise: support 1 and enamelled wire 2.
On support 1, be formed with a plurality of radially spaced coil grooves 11, enamelled wire 2 is dredged around a plurality of coil grooves 11 interior to form a plurality of rings 211, that is to say, one circle enamelled wire 2 forms a ring 211, and the diameter that is positioned at the ring 211 of support 1 inner side (near bracket 1 center) is less than the diameter of the ring 211 that is positioned at support 1 outside (away from support 1 center).Wherein, a plurality of rings 211 are being divided into the ring group 21 that more than three (comprises three) in the radial direction, each ring group 21 comprises the two circles enamelled wire 2 of above (comprising two circles), that is to say that each ring group 21 comprises two above (comprising two) rings 211, wherein the radial spacing between ring group 21 is greater than the radial spacing between every circle enamelled wire 2, in other words, the radial spacing between ring group 21 is greater than the radial spacing between the ring 211 between each ring group 21.That is to say, a plurality of coils that enamelled wire 2 turns to anisotropically arrange.Wherein, in embodiment more of the present utility model, the radial spacing between each ring group 21 can be 3mm～25mm.
According to the coil panel 100 of the utility model embodiment, by a plurality of rings 211 being divided into three above ring groups 21, and the radial spacing between ring group 21 is arranged to be greater than the radial spacing between every circle enamelled wire 2, thereby can make the magnetic line of force that coil panel 100 produces distribute more even, and then make the Distribution of Magnetic Field of coil panel 100 more even, thereby it is inhomogeneous to solve the pan bottom-heated of user in using electromagnetic oven process, easily causes the problem of being burned.
In embodiment more of the present utility model, support 1 is provided with a plurality of radially spaced annular stop muscle 12, and wherein each coil groove 11 is limited by two adjacent backstop muscle 12.Make thus the Structural Tectonics of support 1 simple, easily manufactured easy.
Wherein, in example as depicted in figs. 1 and 2, backstop muscle 12 comprises the first sub-backstop muscle 121 and the second sub-backstop muscle 122, the thickness H of the first sub-backstop muscle 121 is the thickness that 3mm～25mm and the first sub-backstop muscle 121 are greater than the second sub-backstop muscle 122, between every two the first sub-backstop muscle 121, is furnished with at least one second sub-backstop muscle 122.Wherein, clearance distance between the first sub-backstop muscle 121 and the second sub-backstop muscle 122 can be identical, like this, when enamelled wire 2 is wound on coil groove 11 when interior, can be separated out two adjacent ring groups 21 by each the first sub-backstop muscle 121, now each coil groove 11 is interior all can be wound with enamelled wire 2.Make thus the manufacture of coil panel 100 simply, conveniently.
Example shown in accompanying drawing of the present utility model, as shown in Figure 1-Figure 3, ring group 21 is four, between each ring group 21, be provided with a first sub-backstop muscle 121, and from inside to outside, ring 211 quantity in each ring group 21 are respectively three, two, three and five, are provided with a second sub-backstop muscle 122 between the ring 211 in each ring group 21.Be understandable that, only show a kind of concrete example of coil panel 100 in accompanying drawing of the present utility model, it is only in order to describe better the relation between ring group 21 and ring 211, and not in order to limit protection range of the present utility model.
In addition, according to another example of the present utility model, the thickness of a plurality of backstop muscle 12 on support 1 can be identical, is separated with the coil groove 11 that at least one does not hold enamelled wire 2 between between each ring group 21.That is to say, at the interior interval coiling of a plurality of coil grooves 11 enamelled wire 2, thereby construct a plurality of coil groups, can under the prerequisite that does not change original support 1 structure, can produce the coil panel 100 that the utility model proposes thus, can save the cost that again manufactures and designs support 1 thus.
In embodiment more of the present utility model, as shown in figures 1 and 3, support 1 is circular, and each backstop muscle 12 is annular.Like this, support 1 is simple in structure, easily manufactured.Further, be all formed with at least one opening 123 on each backstop muscle 12, each opening 123 is relative in the radial direction.By form opening 123 on each backstop muscle 12, thereby when enamelled wire 2 is wound on support 1, can carry out outlet by the opening 123 from backstop muscle 12, or can carry out wire jumper setting by the opening 123 from each backstop muscle 12, thereby can facilitate the coiling of enamelled wire 2 on support 1.And, by making each opening 123 relative in the radial direction, thereby make the rational in infrastructure of whole support 1, manufacture simple.Be understandable that, the method for winding of coil panel 100 can be prior art, and is well known for ordinary skill in the art, and is not described in detail in this.
In a preferred embodiment of the present utility model, as shown in Figure 1, on the backstop muscle 12 of inner side, be formed with two openings 123, and the backstop muscle 12 that two openings 123 on the backstop muscle 12 of inner side are respectively formed at inner side is along the place, two ends in diametric(al), on support 1, remains and on backstop muscle 12, be formed with an opening 123.By form an opening 123 on residue backstop muscle 12, thereby the structural strength of backstop muscle 12 is increased, and make the positioning action of 12 pairs of enamelled wires 2 of backstop muscle more effective.
In an optional embodiment of the present utility model, enamelled wire 2 coiling on above-below direction be two-layer or two-layer more than.Can further increase the electromagnetic induction effect of coil panel 100 thus, increase heating power, improve heating effect.
In embodiment more of the present utility model, coil panel 100 can also comprise annular magnetic stripe (scheming not shown), and annular magnetic stripe is located on support, and particularly, annular magnetic stripe is located on the upper surface of support 1.Wherein, it should be noted that, the upper surface of support 1 can be the surface at enamelled wire 2 places, that is to say, annular magnetic stripe and enamelled wire 2 can be positioned at the surface, the same side of support 1.By annular magnetic stripe is set, can increase the density of line of magnetic force of coil panel 100, promote the efficiency of heating surface of coil panel 100.
Particularly, on support 1, between each ring group 21, can be provided with for the magnetic stripe groove of annular magnetic stripe is installed, that is to say, annular magnetic stripe is arranged between each ring group 21, magnetic stripe groove is formed on the upper surface of support 1, makes like this easier for installation of annular magnetic stripe.Because the spacing between each ring group 21 is larger, and enamelled wire 2 is not set, by annular magnetic stripe is arranged between each ring group 21, thereby can increases the magnetic line of force quantity between each ring group 21, improve the efficiency of heating surface between each ring group 21.
The utility model has also proposed a kind of electromagnetic oven with above-mentioned coil panel 100, due to even according to coil panel 100 Distribution of Magnetic Field of the present utility model, homogeneous heating, effective, thereby the heating uniformity that can improve thus electromagnetic oven by this coil panel 100 is set, the heating effect of electromagnetic oven and performance are good.
According to other formations of the electromagnetic oven of the utility model embodiment and operation, be all known for those of ordinary skills, no longer describe in detail here.
