Definitions

  • the invention concerns devices for heating by transformation of electric energy into heat.
  • Subject of the invention is a heat radiating mirror obtained by matching the rear face of a mirror, after interposition of an electrically insulating layer, with a flat body formed of an electrically conducting strip of a constant section and thickness measured in microns, that spreads over a geometrical surface placed close together without reciprocal contact.
  • a source of electricity By connecting the terminals of the strip to a source of electricity, heat is radiated through the front transparent face of the mirror.
  • the flat body formed by the electrically conducting strip is matchingly interposed between the rear face of the mirror and a flat heat insulating body.
  • the electrically conducting strip is supported by one electrically insulated face of a metal sheet.
  • the metal sheet is aluminium one of whose faces is anodised for electrical insulation.
  • the face of the metal sheet that supports the electrically conducting strip matches with the rear face of a mirror through an electrically insulating layer.
  • the rear face of the metal sheet that supports the electrically conducting strip matches with the rear face of the mirror.
  • Electric current is preferably of low voltage and high intensity.
  • the reflecting layer of the mirror is advantageously of silver.
  • the flat heat insulating body is preferably of foam plastic material.
  • the electrically conducting strip may be placed in the form of a serpentine, a spiral or some other of a suitable kind.
  • Thermal energy is transmitted directly by the mirror to the great comfort of users who being in a bathroom have little or no clothing on, and need adequate heating, the mirror at the same time being used for ordinary toilet purposes.
  • the heat radiating mirror 10 is obtained from the glass 1 1 with a reflecting layer of silver 12 at the back, associated to a lamina of aluminium 14 with an anodised layer 15 on which a strip of copper 16 is laid serpentinewise, of a constant width with thickness measured in microns.
  • a layer of insulating paint 13 is placed between the mirror and aluminium lamina
  • the various lengths of the copper strip 16 in the form of a serpentine are laid side by side and its ends 17, 18 are connected to a source of electric current of low voltage and high amperage Behind the aluminium lamina is the heat insulating panel 19
  • the effect of the electric current is to make the mirror radiate heat as indi- cated by the arrows 9.
  • Fig. 2 shows a variant of the heat radiating mirror 20, substantially similar to the type described above.
  • the sheet of glass 21 with its backing layer of silver 22 is associated to a sheet of aluminium 24 on which, after interposition of an anodised layer 25, the copper serpentine 26 is placed like that described for the first execution, with terminals 27, 28.
  • the heat insulating panel 29 is fixed onto said sheet 24.
  • Fig. 3 there is an application of the disclosure showing a heat radiating mirror 30, placed in a bathroom 50, supported by a sheet of aluminium 34.
  • Insulating paint 33 is applied between the mirror and aluminium sheet.
  • the terminals 37, 38 of the serpentine 36 are connected to the electric socket 52 on the wall 51 .
  • the heat radiating mirror 30 with glass 31 and layer of silver backing 32 is supported by the body 41 with head 42 for lighting placed above the double basin 40. Behind the sheet of aluminium is the heat insulating panel 39.

Abstract

Cette invention se rapporte à un miroir à rayonnement thermique (10), que l'on obtient en apposant, après interposition d'une couche (13) d'un matériau électro-isolant, la face arrière (12) du miroir contre un corps plat formé d'une bande (16) d'un matériau électro-conducteur ayant une section constante et une épaisseur mesurée en microns, soutenue par une face anodisée (15) d'une feuille d'aluminium (14), sa face arrière étant plaquée contre un corps plat d'un matériau en plastique mousse (19), de sorte que, après connexion des bornes (17, 18) de la bande à une source de courant électrique, il se forme un rayonnement thermique (9) à travers la face avant du miroir (10).
