Embodiment
Embodiment one
Coil panel is applied in electromagnetic oven, the magnetic field of alternately change can be produced under the effect of alternating current, thus the magnetic conduction objects such as the pan in magnetic field range are produced to the dissection of the magnetic line of force, thus heating magnetic conduction object interior molecules, the magnetic conduction object temperature such as pan are raised, realizes Electromagnetic Heating effect.Fig. 1 is the schematic cross-section of the coil panel that the utility model embodiment one provides.Fig. 2 is the structural representation of the coil panel that the utility model embodiment one provides.As depicted in figs. 1 and 2, the coil panel that the present embodiment provides, comprise plate rail 1 and coil 2, coil 2 winding is on plate rail 1, and plate rail 1 upper surface is cambered surface, coil 2 comprises at least two from inside to outside successively around the coil loop arranged, and forms annular gap band 3 between the most inside cord ring 21 of coil 2 and the secondary inside cord ring 22 adjacent with most inside cord ring 21, the external diameter of annular gap band 3 is less than or equal to 120mm, and the internal diameter of annular gap band 3 is more than or equal to 40mm.
Because the upper surface of plate rail 1 is cambered surface, so when coil 2 winding is on plate rail 1, an arc shape equally also can be formed.This arc shape usually and the lower arcuate surface shape of pan and the regularity of distribution of the magnetic line of force match, like this when pan is placed on coil panel, the shape approximation or consistent on pan bottom surface and coil 2 surface, thus make the distance uniformity between coil 2 and pan bottom surface.Concrete, the bonding agents such as epoxy resin can be utilized between coil 2 with plate rail 1 to be connected.Plate rail 1 can be provided with louvre etc., to ensure the heat radiation to coil.
Wherein, coil 2, for close around forming, namely adopts close winding technologe to be closely wound on plate rail 1, coil 2 when coiling, employing be that a circle suffers one and to enclose the land canoe, coil turn is more.Close like this around coil 2, effectively can increase the winding length of unit are, ensure the uniformity of heating, simultaneously the resistance of coil 2 is less, and when heating, the heat that coil 2 produces is also less, not easily produces damage.
When coil 2 is wound on plate rail 1, usually sectional design can be carried out according to the distribution situation of the magnetic line of force.Concrete, coil 2 can comprise at least two coil loop, and multiple coil loop is from inside to outside successively around setting.So different coil loop is corresponding different region, as long as be optimized parameters such as the position of coil loop and sizes, the density of line of magnetic force that each region can be made to produce is substantially equal.
Concrete, an annular gap band 3 can be formed between the most inside cord ring 21 of coil 2 and the secondary inside cord ring 22 adjacent with most inside cord ring 21.And the external diameter of this annular gap band 3 is less than or equal to 120mm usually, and the internal diameter of annular gap band 3 is more than or equal to 40mm.The diameter dimension of annular gap band 3 remains between 40mm-120mm, because the regional magnetic force line within the scope of coil panel φ 40-φ 120mm is comparatively intensive, when coil within the scope of this produces alternating magnetic field, the dissection of the magnetic line of force is the most obvious, thus the heat effect produced magnetic conduction objects such as pans is also maximum, in order to the heat preventing this region from producing is excessive, the region disconnected near two coil loop at coil panel center also should remain within the scope of this, to avoid the magnetic line of force too intensive, ensure the uniformity when heating.
As preferably execution mode, the external diameter of annular gap band 3 should be less than or equal to 90mm, and the internal diameter of annular gap band 3 is more than or equal to 70mm.Because the regional magnetic force line that coil panel is positioned at φ 70-φ 90mm scope is the most intensive, so the region disconnected near two coil loop at coil panel center is preferably arranged in this scope, the intensive uneven situation of the magnetic line of force can be farthest avoided to occur.
Consider the factor such as the installing space of coil 2 and the magnetic field size of coil panel, common, the spacing between adjacent two coil loop remains between 8-20mm.Because be usually provided with protruding magnetic stripe between adjacent coil loop, and magnetic stripe thickness is generally about 4mm, the spacing thus between coil loop at least should be 8mm, to ensure the gap that all there is 2mm between each coil loop and magnetic stripe.Meanwhile, between adjacent two coil loop, spacing should more than 20mm yet, otherwise the spacing disconnected is excessive, can have influence on the energy consumption of coil panel.
In addition, in order to ensure that coil panel is consistent with pan bottom shape as far as possible, reduce the manufacturing process difficulty of coil panel, the inner edge of coil 2 and the difference in height of coil 2 outer rim are usually between 5-30mm simultaneously.Such difference in height scope, the radian of coil 2 and pan bottom shape can be allowed to be consistent as far as possible, both can to have made the spacing uniformity of coil 2 and pan bottom surface, to play good homogeneous heating effect, also can prevent the magnetic line of force of pan bottom periphery from leaking, avoid environmental pollution.
In order to make the energy of coil panel more concentrated, magnetic stripe can also be set the magnetic line of force is guided.Now, plate rail 1 is provided with the hole slot for arranging magnetic stripe; Coil panel also comprises magnetic stripe 4, and magnetic stripe 4 is arranged on the below of coil 2, and magnetic stripe 4 is located in hole slot 11.Concrete, plate rail 1 is provided with positioning hole groove 11, and some positioning bar positions etc., magnetic stripe 4 can be fed through the hole slot 11 for locating, and is arranged on below coil 2.Magnetic stripe 4 is arranged on the side of coil 2, can change the magnetic direction of coil 2, leaks with the magnetic field reducing coil 2, thus the magnetic field energy of coil panel is concentrated heat, and improves the energy utilization efficiency of coil panel.
In the present embodiment, coil panel comprises plate rail and coil, coil winding is on plate rail, and plate rail upper surface is cambered surface, coil comprises at least two from inside to outside successively around the coil loop arranged, form annular gap band between the most inside cord ring of coil and the secondary inside cord ring adjacent with most inside cord ring, the external diameter of annular gap band is less than or equal to 120mm, and the internal diameter of annular gap band 3 is more than or equal to 40mm.Like this can by by the coil of coil panel disconnect remain in the comparatively intensive region of the magnetic line of force, thus the situation avoiding the magnetic line of force too intensive occur, ensure heat time uniformity.
