Definitions

  • the present invention relates to a flat heating component, comprising an electrically resistant heating element embedded in an electrically insulating material and comprised between two metal plates.
  • the invention also relates to the method for manufacturing the aforementioned heating component.
  • the heating component targeted by the invention may consist, for example, of the heating soleplate of an iron or by the heating base of a cooking utensil.
  • the iron soles are generally made of molded metal such as aluminum in which is coated an electric heating resistor of tubular shape.
  • this assembly must ensure a plating of the two plates one on the other in such a way that any hot spot is avoided which would risk causing the breakdown of the heating resistance.
  • this plating must be carried out in such a way that the resistant element is protected from external aggressive agents such as steam and humidity.
  • the object of the present invention is to create a flat heating component which is both inexpensive to manufacture and which fulfills the conditions set out above.
  • the invention thus relates to a flat heating component, comprising an electrically resistant heating element coated in an electrically insulating material and between two metal plates.
  • this component is characterized in that the two metal plates are fixed through gaps made in the heating element and in said insulating material.
  • the two plates are made of laminated metal, preferably of laminated aluminum.
  • the production of the heating component is economical.
  • the welding is carried out by brazing, this brazing being obtained by fusion of a sheet of brazed joint with one and / or the other of the two metal plates.
  • At least one of the plates has bosses engaged in the gaps of the electrically resistant heating element, the welding being carried out between these bosses and the other plate.
  • At least one of the plates has a projection extending over substantially the entire periphery of the plate, the weld being produced between this projection and the periphery of the other plate.
  • This welding thus makes it possible to seal the component with respect to external aggressive agents such as than steam and humidity.
  • the method for manufacturing a flat heating component according to the invention is characterized by the following steps: - the electric heating element is placed on the plate comprising the bosses, by engaging these bosses in the gaps of the heating element, - the second plate is placed on the heating element, - The whole is heated to obtain the fusion of the solder.
  • This operation is carried out without exerting pressure on the plates and preferably under vacuum to avoid any oxidation.
  • the flat heating component which can constitute the bottom of a heating culinary utensil or an iron soleplate, comprises an electrically resistant heating element 1 comprising a sheet 2 of cut resistive metal coated in an electrically material insulating 3 and between two metal plates 4, 5.
  • the two metal plates 4, 5 are fixed to each other (see Figures 3 and 5) by a series of welds 6 produced through gaps 7, 7a made in the resistant heating element 1.
  • the two plates 4, 5 are preferably made of laminated metal and in particular of laminated aluminum.
  • the welds 6 are produced by brazing.
  • This brazing is obtained by melting a brazing sheet 8 co-laminated with one and / or the other of the two metal plates 4, 5.
  • the lower plate 5 has bosses 9, 9a engaged in the gaps 7, 7a of the electrically resistant heating element 1.
  • the welds 6 are produced between these bosses 9, 9a and the surface 4a of the other plate 4 which is perfectly plane.
  • the plate 5 has a projection 10 extending over substantially the entire periphery of the plate, the weld being produced between this projection 10 and the periphery 4b of the other plate 4.
  • This projection 10 extends over the entire periphery of the plate 5, with the exception of a small area provided for the passage of the electrical connections 12, 13 of the heating element. The sealing of this area is obtained by other means not shown.
  • the resistive metal sheet 2 of the heating element 1 is for example covered by two sheets of fibrous material such as paper impregnated with phenolic or silicone resin, the connection between these sheets of fibrous material and the metal sheet being produced by heating to polymerize the resin.
  • the bosses 9, 9a can be obtained by semi-cutting the plate 5 by means of punches applied to the face of the plate opposite to that where it is desired to make the bosses. This is what explains the presence of cavities 11, 11a on this opposite face, in line with the bosses 9, 9a.
  • the procedure is as follows: the electrical heating element 1 is placed on the plate 5 comprising the bosses 9, 9a, 10 by engaging these bosses in the gaps 7, 7a of the heating element 1, - the second plate 4 is placed on the heating element 1, - the whole is heated to obtain the melting of the solder layer 8.
  • the heating of the assembly is carried out in a vacuum enclosure (of the order of 10 ⁇ 5 torr) in order to avoid any oxidation.
  • the two plates 4, 5 are made of laminated aluminum alloy sold under the reference 3003 by the company Pechiney.
  • the brazing sheet 8 collaminated on the plate 5 can be made of an aluminum-silicon alloy as sold under the reference 4104 by the company Pechiney.
  • This brazing sheet 8 has a melting point of the order of 577 ° C. which is lower than that of the alloy constituting the plates 4, 5.
  • solder between the plates 4, 5 can also be produced by means of solder pads deposited on the bosses 9, 9a and the projection 10.
  • the plates 4, 5 could also be made of mild steel, stainless steel, copper, brass, etc. provided that the solder is suitable for these metals or alloys.
