Further, be provided with a dividing plate between described first coil and second coil, described second coil is arranged on the described dividing plate.
Further, described dividing plate is provided with the some baffle plates that are used to isolate second coil, and adjacent screen forms the wire casing of ccontaining second coil.
Further, described coil bracket is provided with the some baffle plates that are used to isolate first coil, and adjacent screen forms the wire casing of ccontaining first coil.
Further, the independent coiling respectively of first coil and second coil, described first coil and second coil also connect.
Further, the second surface of described coil bracket also is provided with the draw-in groove that is used to place magnetic stripe.
Preferably, described draw-in groove is spoke-like distribution.
Preferably, described magnetic stripe is poly-magnetic ferrites.
Compared with prior art the utlity model has following beneficial effect: a kind of electromagnetic heating coil dish that the utility model embodiment provides, adopt bridging coil, the coil internal resistance is low, the heat efficiency height of coil panel conversion; Adopt double-decker, technology realizes simple.

Embodiment
Clearer for technical problem, technical scheme and beneficial effect that the utility model is solved, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Fig. 1 is the generalized section of the utility model embodiment coil panel; A kind of electromagnetic heating coil dish comprises coil bracket 1, is positioned at the winding section on the described coil bracket first surface, is wound with first coil 31 on the described winding section, also comprises second coil 32 that is arranged on the described winding section; Described first coil and second coils from parallel connection of coils.The utility model coil panel adopts bridging coil, and the coil internal resistance is low, the heat efficiency height of coil panel conversion; Adopt double-decker, technology realizes simple.
In Fig. 1, be provided with a dividing plate 2 between first coil 31 and second coil 32, can effectively prevent first coil 31 and 32 short circuits of second coil.Be equipped with the some baffle plates 7 that are used for retarder on coil bracket 1 and the dividing plate 2, adjacent screen forms wire casing, the wire casing that forms on the coil bracket 1 is used to place first coil 31, and the wire casing that forms on the dividing plate 2 is used to place second coil 32, can effectively prevent turn-to-turn short circuit.The wire casing that forms on wire casing that forms on the coil bracket 1 and the dividing plate 2 can be called double-deck wire casing, and this bilayer wire casing structure makes coil be more convenient for fixing, and has guaranteed structural strength.Be arranged at first coil 31 of coil bracket 1 winding section and second coil 32 on the dividing plate 2 and can distinguish independent coiling, at first with first coil 31 and the 32 separately coilings of second coil, line end with two ends after the coiling connects together respectively, form two and connect after wire wrap terminal 4.On coil bracket 1 and dividing plate 2, be equipped with some baffle plates 7, so first coil 31 and second coil 32 can independently coilings in wire casing.When first coil 31 and 32 coilings of second coil, can be along the pointer coiling, also can be counterclockwise coiling, and first coil 31 and/or second coil 32 can be introduced the outer ring from inner ring and draw, and also can introduce inner ring from the outer ring and draw.
, can fix because withholding of dividing plate 2 arranged for first coil 31 on the coil bracket 1, save cost without resin.Be provided with dividing plate between first coil 31 of coil bracket 1 and second coil 32 in the present embodiment, such structure extensibility is strong, dividing plate 2 and coil bracket 1 can be taken apart, and same coil bracket can be done the improvement of various coil windings and distribution, reach the effect of one module multiple usages.As required, on coil bracket 1, can also be provided with tertiary coil, can also be provided with dividing plate between the tertiary coil and second coil, tertiary coil, first coil and second coils from parallel connection of coils.
Fig. 2 is the vertical view of the utility model embodiment coil panel, and Fig. 3 is the upward view of the utility model embodiment coil panel; In conjunction with two figure, can see at coil bracket 1 back side also being provided with the draw-in groove 5 that is used to place magnetic stripe 6 that draw-in groove 5 is bar spoke shape and distributes.Magnetic stripe 6 is poly-magnetic ferrites in the present embodiment, also can select the material of suitable magnetic permeability according to demand for use, for example can be high-permeability material.Should form by bottom ferrite, outer ring ferrite, inner ring ferrite three parts by poly-magnetic ferrites.The setting of inner ring ferrite has than the long-pending bigger characteristics of normal coil disk body, has improved existing coil panel inner ring magnetic field cancellation than important disadvantages.The inner ring ferrite has nearer distance apart from the coil panel center simultaneously, and is littler than the internal coil diameter of common dual layer discs.This structural improvement of present embodiment the underheated shortcoming in existing coil panel center.Because the influence value of the utility model coil panel has not only been regulated in the ferritic reinforcement of inner ring, and improved the shortcoming that the center heating is weak, the magnetic field utilance is low effectively.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
