Definitions

  • the present invention relates to an electric surface heater according to the preamble of claim 1.
  • a heating conductor in the form of a flat wire is imprinted in a meandering manner on a radiation foil, laminated or applied in a similar manner as an electrical heating device.
  • the radiation film is in turn connected to a thermal insulation panel to form a structural unit.
  • the assembly consisting of heat conductor, radiation foil and thermal insulation board is attached to the back of a plate made of thermally conductive material. The construction is expensive to manufacture and therefore expensive.
  • a surface heater which is a plate of thermally conductive material, eg. As marble, as well as an additional support plate having a heated cover layer for heating the plate.
  • finely distributed graphite particles are housed in a heat-resistant plastic film as a heating element. This arrangement is complex in construction and expensive to implement.
  • the object of the present invention is to provide a novel electric surface heater of the type mentioned above, which ensures a particularly easy-to-implement construction, but at the same time unfolds an increased compared to the prior art heating efficiency.
  • the above object is achieved in the generic surface heating element in that are provided as electrical heating carbon fibers, which are components of a temperature-resistant support.
  • the use of carbon fibers makes it possible to introduce the latter into a flat carrier in a simple and cost-effective manner, for example weaving.
  • the use of the carbon fibers ensures advantageous efficiency and high flexibility in heating the plate.
  • the carrier is a fabric of temperature-resistant fibers.
  • This fabric can be made based on conventional weaving techniques.
  • the fabric is a glass fiber fabric. This is particularly suitable because of its temperature resistance to absorb carbon fibers.
  • the carbon fibers are woven into the fabric, for example in the form of weft threads.
  • the nature of the use of carbon fibers also makes it possible to provide a different arrangement of the same on the carrier in a simple manner. This serves to heat certain areas of the carrier, for example its edge areas, more strongly, in turn, to achieve a better ratio of heating power of the surface heating element and necessary electrical energy.
  • the plate can thereby be operated with an ideal heating power distribution.
  • the arrangement of the carbon fibers on the carrier is preferably different, so that the heating power in the edge region of the carrier, for example, is higher than in the central region.
  • the distance of the carbon fibers in the fabric from each other can be varied to ensure such a different arrangement.
  • the carrier is connected in a simple manner with the plate by sticking, so that expensive installation work or processing of the plate omitted.
  • a preferably inside heat-reflecting cover plate may be provided on the side opposite the plate of the carrier for protection against mechanical impairment.
  • the carbon fibers can be operated in regions with different electrical power, so that in this way sets a different heating effect with respect to the respective position on the plate.
  • the carbon fibers may also have a different electrical resistance so that different heating powers result when a current is applied.
  • a part of the carbon fibers is activated so that this part of the carbon fibers can generate heat energy, whereas the other part of the carbon fibers is deactivated and does not generate heat energy.
  • an energy profile can be created across the surface of the carrier.
  • the deactivation is conveniently carried out by simply cutting the carbon fibers at the areas where the heat is to be withdrawn something.
  • Reference numeral 1 in Fig. 1 identifies the surface heating element in its entirety. It includes a massive plate 2 made of good conductive material such. As natural stone such as marble, ceramics or glass. Also metal would be suitable. The plate 2 serves to radiate the heat stored in it to the outside, in particular to the front.
  • a flat carrier 3 made of a fabric made of temperature-resistant fibers, for example Glass fibers 4 and carbon fibers 5, which are provided as heating elements.
  • the carbon fibers are connected via a suitable electrical connection 10 to the power grid.
  • both at the front and at the rear there is a respective foot part 6 or 7, so that the surface heating element 1 can be placed at the desired location.
  • cover plate 6 on the back of the surface heating element 1, which serves to protect the carrier 3 from mechanical influences.
  • the carrier 3 is glued as a fabric in a simple manner on the back of the plate 2.
  • the adhesive layer is in Fig. 2 denoted by the reference numeral 8.
  • Fig. 1 how out Fig. 1 can be seen, the carbon fibers 5 in the carrier 3 in a different arrangement, in the example of Fig. 1 arranged at different distances A.
  • an elevated temperature for example 110 ° C.
  • the central part acts on the plate 2 than in the middle region (for example 100 ° C.).
  • the cover plate 6 has a heat reflection layer 9 which ensures that the heat radiated to the rear by the carbon fibers 5, that is, the heat radiated backwards. H. is reflected in the direction of the plate 2.
  • Fig. 3 shows in a simplified sectional view of the carrier 3, which represents a tissue.
  • the tissue of individual crosswise extending glass fibers 4 individual carbon fibers 5 are woven in a corresponding orientation, for example in the weft direction, in Fig. 3 with a constant distance to each other.
  • the distance between the carbon fibers 5 is then changed as needed or individual carbon fibers 5 in the weave pattern of the carrier 3 is deactivated (see the following), in order to ensure increased or reduced heating power in this area.
  • a part of the carbon fibers which are woven into the carrier 3 is deactivated by being severed. Consequently, in the region of these severed carbon fibers, an electric current flow is not possible and thus heating of the relevant carbon fiber is not possible.
  • the setting of a targeted heating characteristic over the total area of the carrier 3 can be adjusted.
