Fig. 1 represents the structure that can remove an embodiment of electromagnetic electric heating bedding of the present utility model, and what show among the figure is the state of the planar heat producing body 20 embedding bedding face shields 10 of top and bottom.

With reference to Fig. 2, shown the structure of top and bottom planar heat producing body 20 among the figure in detail.

Top planar heat producing body 20 and bottom planar heat producing body 20 constitute one group, form identical construction.

Each planar heat producing body 20 is made of two busbars 24 with lead 22, many heating wire 26 and the soft linings 28 of electric heating as the insulation conductive heating unit.

2 busbars 24 of configured in parallel on the soft lining 28 of electric heating, many thin heating wires 26 equally spaced closely are connected with above-mentioned busbar 24 vertical also maintenances.

And the top of top and bottom planar heat producing body 20 and lower wire 22 connect respectively as shown in Figure 2 alternately, form one group of planar heat producing body.

At this moment, in the process of making planar heat producing body, be individually formed one group of planar heat producing body respectively, in the process of making the electric heating bedding, when embedding above-mentioned bedding face shield 10, can be overlapping up and down, with top and lower wire 22 is mutual respectively connects, also can just the overlapping up and down card dress of one group of planar heat producing body be connected top and lower wire 22 respectively more alternately, form one group of planar heat producing body thus from the manufacture process of planar heat producing body.

Under the former situation, can finish to many branch companies workload allocations, so when in a large number, promptly making top or bottom planar heat producing body (because of same structure so can realize) respectively advantageous particularly.

Refer again to Fig. 1, the power line of above-mentioned planar heat producing body 20 is connected in the inside portion of the terminal box 12 that is connected with bedding face shield 10, and the outside portion of terminal box 12 is connected with the plug 14 that is used to apply power supply.

Be filled with the heat insulating ability filler in the inside of bedding face shield 10.

Fig. 3 represents another embodiment of the present utility model.

In this embodiment, top and bottom insulation conduction fever body 36 constitute one group, embed in the bedding face shield 10.

Above-mentioned insulation conductive heating unit 36 is to coat one deck insulation heat stable resin on heating wires such as copper, nickel, alloy.

Be extruded with lead 32 at above-mentioned insulation conductive heating unit 36, as shown in FIG., when forming one group, the upper left side lead is connected respectively with lower-left side lead alternately with lower right side lead, upper right side lead.

Fig. 4 represents another embodiment of the present utility model.

In this embodiment, insulation conductive heating unit 46 and insulated electric conductor 42 be as one group, embeds bedding face shield 10 and constitute.

At this moment, an end of above-mentioned insulation conductive heating unit 46 and insulated electric conductor 42 interconnects, and its other end is connected with power supply respectively.
