Description
Technical field
The utility model relates to a kind of electric heating device, relates in particular to a kind of electric heating device of sheet.
Background technology
Existing space heater adopts rigidity heating core usually, as the ceramic heat pipe etc.The manufacturing process complexity of this type of heating core, the manufacturing cost height, it is big to take up room during use, and begin to heat the back heat to around distribute, promptly the heat directionality of distributing is poor.In addition, because this type of heating core volume is bigger, so radiating rate is slow, cause internal temperature very high, not only energy utilization rate is low, also scalds human body easily.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, the heating directionality is good, the electric heating sheets of energy-saving safety.
Technical solution adopted in the utility model is:
A kind of electric heating sheets comprises: a pair of film basic unit that possesses the insulation on adjacent surface; Be folded in the heating of a slice at least sheet between the adjacent surface of described a pair of film basic unit; Be used for connecing electric winding displacement with what described heating sheet and external power supply were electrically connected.Describedly connect electric winding displacement and be clipped between described film basic unit and the described heating sheet, described electric heating sheets also comprises at least one sewing line that is used for described film basic unit, the sheet that generates heat, connects the insulation that electric winding displacement is sewed together.
Described electric heating sheets also comprises: between described heating sheet of a slice at least and the described surface that is electrically connected that connects electric winding displacement, accompany the electric conductor of sheet, this electric conductor by described sewing line and described heating sheet, describedly connect electric winding displacement and described thin film based layered suture is made for one.Described electric conductor is silver application layer.On the zone, at least one place of the outer surface of described film basic unit, fixedly be pasted with the sealant of waterproof and insulation, the sealing ply possess above the zone of described sewing line and with this regional seal envelope.Fix by gluing between described film basic unit and the described sealant.Described heating sheet is at least 2, has the space between each adjacent described heating sheet.Each described heating sheet connects electric winding displacement and is in parallel by described.Fix by viscose glue between the apparent surface of a pair of described film basic unit.
The electric heating sheets of implementing according to the utility model has the following advantages:
1, adopt flexible sheet material as heater element, heat can not accumulate in core inside, so the radiating efficiency height, the temperature of heater element is relatively low, is difficult for taking place the scald accident.
2, the heat radiation directionality of flexible sheet material is good, and heat straight line forwards, backwards distributes.
3, since the heating sheet have certain width, so even some the heating sheet sustain damage, also can not open circuit and influence integral body heating efficiency.
4, the overall structure of this electric heating sheets is simple, and light weight is efficient, and implementation cost is low.

Embodiment
Below in conjunction with drawings and Examples the utility model is described.
The electric heating sheets of implementing according to the utility model comprises: a pair of film basic unit 2 that possesses the insulation on adjacent surface; Be folded in a plurality of heating sheets 1 between the adjacent surface of this a pair of film basic unit 2; Be used for connecing electric winding displacement 3 with what these heating sheets 1 and external power supply were electrically connected; Be attached to the heating sheet 1 with connect electric winding displacement 3 contacted lip-deep aluminium foil electric conductors 5; Be attached to two block length strip form film sealants 6 on film basic unit 2 outer surfaces.
As shown in Figures 1 and 2, described a plurality of heating sheets 1 are strip, and longitudinally parallel arrangement mutually.Connect electric winding displacement 3 and possess positive wire and cathode conductor, can contact with the not ipsilateral of heating sheet 1 respectively, also can contact with the homonymy of heating sheet 1.At an end of heating sheet 1, horizontally set connects the positive wire of electric winding displacement 3, and this positive wire contacts with all heating sheets 1 successively; At the other end of heating sheet 1, horizontally set connects the cathode conductor of electric winding displacement 3, and this cathode conductor contacts with all heating sheets 1 successively.The feasible sheet 1 that respectively generates heat of this method of attachment is parallel with one another.
As shown in Figure 2, electric conductor 5 is clipped in heating sheet 1 and connects between the electric winding displacement 3, and this electric connection mode makes heating sheet 1 and the contact-making surface that connects electric winding displacement 3 increase, and conduction is stable.Electric conductor 5 can also be silver application layer.
A pair of film basic unit 2 is attached to all heating sheet 1, electric conductors 5, connects the outer surface of electric winding displacement 3, with its complete covering.Undertaken bondingly between this a pair of thin film based layer 2 by heat-resistant adhesive, film basic unit 2 and the heat-resistant adhesive that is used to bond all need to tolerate at least 200 degrees centigrade high temperature.
Each heating sheet 1 with the contacted position of same polar conductor that connects electric winding displacement 3 roughly linearly along transversely arranged, make a sewing line 4 along this horizontal line, with film basic unit 2, connect electric winding displacement 3, electric conductor 5, heating sheet 1 is all made and is become one.Sewing line 4 respectively has one at positive wire that connects electric winding displacement 3 and cathode conductor position.
Adopt sewing line 4 to make each parts, be connected firmly, can avoid film basic unit 2 because of the contingent displacement of temperature distortion.And this kind fixed form is simple and easy to implement, and is with low cost, good fixing effect.And fixing flexibility height is controlled sewing position easily, or makes many sewing lines 4 increase firmness and reliabilitys.
As shown in Figure 2, the outer surface in film basic unit 2 is pasted with strip thin film encapsulation layers 6, and sealing layer 6 extends along the length direction of sewing line 4, overlaps on the electric conductor 5, and will have regional complete the covering of sewing line 4.Sealing layer 6 waterproof and insulation fit tightly with thin film encapsulation layers 6 mutually by heat-sealing, method such as gluing, play waterproof sealing, prevent the effect of getting an electric shock.
The electric heating sheets of implementing according to the utility model can be widely used on the various civilian warmers.Adopt rigid element that this flexible electrical heating plate is fixed, will connect electric winding displacement 3 again and be connected to external power supply, promptly make space heater.There is the gap between each heating sheet 1 in the electric heating sheets, if adopt optically transparent material to prepare film basic unit 2, and set up reflecting element in a side of electric heating sheets, then the heat that the side from this electric heating sheets can be exhaled reflexes to opposite side by the gap, and with the heat accumulation that directly exhales from opposite side together, orientation is dispersed, and obtains high heating efficient.
Because the utility model very thin thickness so also a plurality of electric heating sheets can be arranged side by side, improves heating power.
As mentioned above, we are illustrated according to aim of the present utility model fully, but the utility model is not limited to the foregoing description and implementation method.The practitioner of correlative technology field can carry out different variations and enforcement in the scope of technological thought permission of the present invention.
