Definitions

  • the present invention relates to the field of equipment household appliances, in particular stoves, ovens, dishwashers and microwave appliances with one or more glass panes hardened, generally forming control panels, and relates to a process for producing control panels, in particular for such Appliances.
  • the glass elements used for this purpose are generally pieces of aesthetics decorated by serigraphy of enamel or ink.
  • the decor includes, more often, a colored background, a brand logo of another color, and indications for positioning the control buttons of the device, as well as, sometimes more or less illuminated symbols indicating the operating status of the device.
  • the symbols, logos, markings, status indications of operation are generally obtained by screen printing operations successive, allowing an impression of the colors on the glass, at the places desired, while respecting the positioning relative to the glass element.
  • EP-A-0 391 848 a method of decoration consisting in locally modifying the pigmentation of a layer of coating by means of a laser beam. This process uses a layer of coating particularly suitable for subsequent decoration by laser beam and cannot be used for any coating layer.
  • JP-A-61 108487 describes a method of engraving by laser beam, in which the glass is protected, in areas that should not be engraved, by a protective coating which is later removed.
  • the object of the present invention is to overcome these drawbacks by proposing a method for producing control panels, in particular for household appliances, making it possible to obtain individual blinds personalized by combining screen printing with decorations common to a range of banners with a specific decoration.
  • the process for producing control panels essentially consists in carrying out minus a personalized laser engraving on at least one screenprint already applied on a raw basic glass strip, by removing decorations, symbols or corresponding signs in the screen-printed layer, then to cover these engravings a coating of a different color, immediately following the operation of engraving or in a separate operation, by manual or automated filing.
  • the method of making control panels in particular for household appliances, consists essentially to carry out at least one personalized laser engraving of decorations, symbols or signs 1 and / or 2 on at least one screenprint 3 and / or 4 already applied on a raw base 5 glass strip.
  • the engravings corresponding to the decorations, symbols or signs 1 and / or 2 can be coated with a different color coating immediately following the engraving operation or during a separate operation. by a deposit manual or automated.
  • the decorations, symbols or signs 1 and / or 2, provided around the holes 6 and 7, are, for example, respectively of white and red in color.
  • the basic raw headband 5 can be made of tempered glass and the screenprint (s) 3 and / or 4 can be in vitreous enamel.
  • Figure 3 of the accompanying drawing shows a basic raw strip 5 provided with a screen-printed logo 3, for example ABC, on a background also screen-printed 4, the logo being of a given color and the background of another color, know, respectively in gray and black.
  • the raw strip 5 can also be provided with two holes 6 and 7.
  • a range of household appliances may well have strips of the same geometry and drilling, with the same bottom and the same logo, but with inscriptions and or other signs, including sizes and the colors are different, or even positioned differently.
  • the invention proposes to produce the headbands from a raw strip 5.
  • the decorations, symbols or signs 1 and / or 2 are engraved by a laser cut of the bottom 4. Such a cut can be done in seconds.
  • the embodiments according to Figures 1 and 2 can be obtained very quickly and without the use of tools particular.
  • the cutting of the engravings corresponding to the decorations, symbols or signs 1 and / or 2 is advantageously carried out by means of a laser numerical control. This results in great flexibility with regard to the decors, symbols or signs 1 and 2 to be produced as well as a perfect execution of these decors, symbols or signs 1 and 2. In addition, the number of variants in a range becomes unlimited. Thus, the process has only been described with regard to etching. from the bottom 4, however, the engraving of the logo 3 is also possible. for example to modify its appearance. It is also possible to realize the logo 3 directly on the bottom 4, by laser engraving. In such a case, only the background 4 would be screen printed on the raw banner 5.
  • the process according to the invention therefore makes it possible to personalize infinity within a very short time of the raw bands 5 kept in stock and which can form the basis of a range of glass elements for device control.
  • These raw headbands being common to many variants of headbands. they can be produced in large quantities, with reduced costs for series produced.
  • the raw headband of base 5 may consist of a glass with a reflective layer on the front face.
  • this reflective layer being provided with decorations, symbols or signs by etching laser, said decorations, symbols or signs may be covered with a coating of color deposited on the back. So, by this cutting in precise places, in more than the enamel cut on the back, the decorations, symbols or signs are perfectly highlighted, due to the filling of the corresponding engravings by the color coating, without being attenuated by the reflective layer.
  • This mode of realization allows to obtain bright colors deposited on the back of glasses reflective, replacing front and back screen prints on the same glass element.
  • the method according to the invention does not provide for a glass etching by laser, but a simple removal of part of the layer of screen-printed coating, without deterioration of the glass detrimental to the aesthetics, this etching being followed by deposition of a layer of a coating of another color.
