Definitions

  • a room heating element consisting of a ceramic molded body, which is provided on the side facing away from its visible side with a flat heating conductor in the form of an electrical resistance coating made of an electrically conductive ceramic glaze, in which the electrical resistance coating is formed as a resistance layer from a material in which non-metallic, large specific surface area, electrically conductive particles which do not change their electrical conductivity significantly when the temperature rises are embedded in an electrically non-conductive or poorly conductive carrier substance and this material is applied in such a way that the resistance coating has a uniform electrical and thermal conductivity.
  • a special form of such a space heating element is e.g. B. a large wall, floor or ceiling panel.
  • contact is made with the electrical resistance coating, in particular through contact elements arranged symmetrically on the electrical resistance layer.
  • contact elements arranged symmetrically on the electrical resistance layer.
  • the invention has set itself the task of designing the electrically conductive resistance coating of the clothing body so that this detachment either no longer occurs directly from the fastening base or from an insulating layer placed over it, and furthermore an improvement in the heating properties of the space heating element is brought about.
  • the resistance layer in the form of an electrically conductive resistance glaze is covered by a layer of non-conductive or poorly conductive ceramic glaze with a carrier substance of the same ceramic composition as that of the resistance glaze but with built-in kaolin particles and the structure made of ceramic Molded body, electrically conductive ceramic glaze and ceramic Ab
  • the cover layer is heated to below the quartz transformation point ( ⁇ 750 ° C) and the resistance layer and cover layer are burned onto the ceramic clothing body.
  • any organic insulating coating adheres to such a coated body of clothing without any problems.
  • an electrical current passage which is uniform over the surface is achieved in that the contacting of the electrical heating layer is carried out in such a way that the contact elements or the contact layer is applied directly to the ceramic shaped body, this layer being in a ramp shape to the outer edge of the ceramic molded body grows and the ramp height is measured according to the thickness of the heating layer and the ramp width is more than fifty times this thickness.
  • the heating layer thickness was 120 u and the width of the contact layer was 15 mm. Furthermore, this measure reduces the tendency for the contact elements or contact layer to detach.
  • contact layer is applied directly to the back of the ceramic molded body as the first process step, followed by the application of the electrical heating layer as the second step.
  • cover layer is applied and the entire structure is then subjected to a firing or heating process in a fourth step.
  • the electrical resistance coating 2 is composed of a carrier substance 5 and conductive particles 4 embedded in this carrier substance.
  • the cover layer 3 is composed of the same carrier substance 5 and kaolin particles 6 embedded therein.
  • FIG. 2 shows a space heating element as described in EU-A-0 158 091, which is made up of a ceramic molded body 1, an electrical resistance coating 2 and a contact element 7.
  • FIG. 3 shows an embodiment of the space heating element according to the invention comprising an electrical resistance coating 2, a cover layer 3 and a contact element 8.
  • This contact element 8 grows in a ramp shape at 9 towards the outer edge of the ceramic molded body.
  • the contact element which can be formed by a contact layer, is formed in the exemplary embodiment shown with a substantially triangular cross section.
  • the maximum ramp height 10 corresponds to the layer thickness 11 of the electrical resistance coating 2.
  • the width 12 of the contact element is more than fifty times the thickness or thickness 11 of the electrical resistance coating 2. From FIG. 4 it follows that the contact element, on the two opposite Long sides of the space heating element is formed.
  • the space heating element is expediently designed as a large wall, floor or ceiling cladding panel, which has side dimensions of 60 ⁇ 60 cm, in particular as a square panel.
