Background technology

The electromagnetic oven of Xiao Shouing in the market, its inner coil panel is made up of coil windings, support and magnetic stripe three parts, and wherein coil windings adopts the mode coiling of individual layer coiling more, according to the watt level of electromagnetic oven, for reaching certain inductance value, the coiling number of turns of coil windings is also different, and for more powerful electromagnetic oven, the coiling number of turns of its coil windings increases, the drum stent diameter increases, not only manufacturing cost improves, and Distribution of Magnetic Field is also disperseed, and is unfavorable for concentrating heating; Simultaneously, the thermal diffusivity of this common individual layer densely packed coil dish is also relatively poor, and has the risk of turn-to-turn short circuit.

Summary of the invention

The purpose of this utility model is to consider the problems referred to above and a kind of reasonable in design, compact conformation, low cost of manufacture and magnetic field concentration, multi-layer intercrossed formula coil disc of electric stove that the thermal efficiency is high is provided.

The technical solution of the utility model is: a kind of coil disc of electric stove, comprise coil windings, support and magnetic stripe, be provided with some between the inside and outside circle body of its medium-height trestle radially in order to the groove position of magnetic stripe to be installed, the upper surface of groove position is provided with the wrapping post of the concentric arrangement of plurality of vertical, form winding slot between every adjacent wrapping post, enamel-covered wire is wound on and forms coil windings in the winding slot, it is characterized in that described wrapping post wherein one group be divided into two and form two groups narrower dislocation wrapping post, form the dislocation winding slot between every adjacent dislocation wrapping post, enamel-covered wire is wound on the support by winding slot, and forms multi-layer intercrossed formula coil windings by the coiling that misplaces of dislocation winding slot.

The wrapping post of two misplace wrapping post and vicinities of the described two groups narrower nearly inner edge of dislocation wrapping post links into an integrated entity, one group of dislocation wrapping post inner edge position is provided with entrance hole therein, the outer fringe position of another group dislocation wrapping post is provided with outlet guide groove radially, and the support outer edge surface of outlet guide groove outer end oral area is provided with wire hole.

Be respectively arranged with the boss that can wrap magnetic stripe more than two on the radial sidewalls of described magnetic stripe mounting groove position by hot pressing.

The part winding slot of described support outer rim is provided with the pressure welding portion that can wrap coil windings by hot pressing.

The corresponding end of described dislocation wrapping post limit is circular arc slightly.

The utility model is provided with respectively into and out of the structure in line hole owing to having adopted on dislocation winding slot and the inside and outside edge of online disc carrier, make that coil windings can be by the therefrom mind-set periphery coiling of dislocation winding slot, after once finishing the individual pen multilayer winding, next circle of coiling that misplaces is again reduced to the interlayer electrical potential difference minimum, and least number of times simultaneously misplaces, production efficiency is the highest, under the prerequisite that ensures effective heating surface (area) (HS, make firepower more concentrated, heat more even; Simultaneously each layer line circle and between can carry out multi-layer intercrossedly, between the adjacent enamel-covered wire room can be set, be beneficial to and evade the dry combustion method zone, not only quality is more stable, the product efficiency also is increased dramatically.

Fig. 3 is the structural representation of coil panel described in the utility model.

The specific embodiment

As Fig. 1, Fig. 2, shown in Figure 3, the utility model coil disc of electric stove, comprise coil windings 1, support 2 and magnetic stripe 3, be provided with some between the inside and outside circle body of its medium-height trestle 2 radially in order to the groove position of magnetic stripe 3 to be installed, the upper surface of groove position is provided with the wrapping post 21 of the concentric arrangement of plurality of vertical, form winding slot between every adjacent wrapping post, enamel-covered wire 11 is wound on and forms coil windings 1 in the winding slot, wherein said wrapping post 21 is higher, wherein one group of wrapping post is divided into two and forms two groups narrower dislocation wrapping post 22, form the dislocation winding slot between every adjacent dislocation wrapping post 22, enamel-covered wire 11 is wound on the support 2 by winding slot, and forms multi-layer intercrossed formula coil windings 1 by the coiling that misplaces of dislocation winding slot.

The wrapping post of two misplace wrapping post and vicinities of described two groups narrower dislocation wrapping post 22 nearly inner edge links into an integrated entity, one group of dislocation wrapping post inner edge position is provided with entrance hole 23 therein, the outer fringe position of another group dislocation wrapping post is provided with outlet guide groove 24 radially, and the support outer edge surface of outlet guide groove 24 outer end oral areas is provided with wire hole 25.

Be respectively arranged with the boss 26 that can wrap magnetic stripe more than two on the radial sidewalls of described magnetic stripe mounting groove position by hot pressing.
