Definitions

  • the present invention relates to a reinforced lid for household appliances, which combines optimal functional performance, both from the point of view of mechanical resistance and preservation with respect to the humid environment in which it is to work, with a reduced manufacturing cost.
  • the invention is of special application for obtaining those covers with which the upper enclosure of domestic washing machines is carried out.
  • the invention also concerns the method of manufacturing said lid.
  • the structure known and most widely used in the covers of washing machines is formed by a wooden chipboard, covered with a melamine paper and glued to a molded plastic frame, using adhesives or resins, either directly or between two frames, upper and lower.
  • the board and frame are usually joined by means of two adhesive cords on each side of the board, so that they protect their non-melamine coated edges from moisture.
  • the two frames between which the board is located are ultrasonically welded, protecting its perimeter by means of an elastic joint to confer tightness.
  • the most durable and therefore desirable solution would be to replace the chipboard board lid, whose living matter (wood chips) is highly hygroscopic which, due to the inevitable presence of moisture in the washing machines, constitutes a permanent risk of degradation.
  • injected plastic caps have been used that have not given satisfactory results, since they only meet the technical requirements demanded by the manufacturers of household appliances, those made of thermoplastic materials whose cost exceeds competitive values.
  • the purpose of the invention that constitutes the object of this Patent consists in the elimination of the inconveniences of the use of wood chipboard boards in washing machine tops, replacing them with other suitable materials, capable of fulfilling the required technical requirements.
  • Mechanics They tend to prevent and prevent the possible breakage of the lid, especially while the washer is in operation, due to an excessive and even inadequate load: for example, perching on the cover, in which case the damage caused by the breakage of the cover would accumulate the caused to the person.
  • the required mechanical resistance is quantified at 1,000 Newtons in a central area of the 20x20 ctn lid. and 800 N. at the edges.
  • the reinforcements consist of steel strips of reduced thickness, arranged in planes perpendicular to the inside of the cover, parallel to each other and to the axis of articulation of the cover and equidistant.
  • the structure of the lid comprises: a plastic panel of low mechanical performance, formed in the molding process, whose upper and outer face is covered with a sheet of melamine adhered with thermoactive glue or a transparent film decorated by its inner face, adhered in the molding process, the panel being reinforced with metal profiles according to the preceding description, the assembly being injected with a high-performance plastic frame, which embraces it by its edges.
  • the lid manufacturing process reinforced includes the following consecutive operations:
  • the low-performance plastic panel and the over-injected frame that hugs it by its edges is replaced by a single piece constituting the panel and the frame, molded with low-performance material (recycled ) and completely covered with transparent thermoforming film and decorated by its inner face of application on the single piece of panel and frame.
  • the low-performance plastic panel and the over-injected frame that hugs it by its edges is replaced by a single piece constituting the panel and the frame, molded with virgin material (first use ), being covered the part of the single piece corresponding to the panel, with melamine paper adhered with thermoactive glue to the top face of the plane of the lid.
  • the last injector destined to the superinjection of the frame is dispensed with, since of the two injectors parallel the finished covers will be finished.
  • the low-performance plastic panel and the over-injected frame become independent, modifying the configuration of the panel-frame joint so that it, instead of embracing its edges to the panel, is it overlaps it by its upper perimeter zone, both pieces being joined by an adhesive cord that contours the bottom or inner side of the panel, between the edge of the panel and the inner face of the walls of the frame, the panel being covered with melamine paper adhered with thermoactive glue to the upper face of the lid plane.
  • the low-performance plastic panel (recycled) and the frame injected with virgin material become independent, modifying the configuration of the panel-frame joint so that it, instead of hugging its edges to the panel, it is superimposed on it by its upper perimeter zone, both pieces being joined by an ultrasonic welding cord that contours the upper or outer face of the panel, between the edge of the panel and the inner side of the part superimposed on the frame, the panel being covered, with melamine paper adhered with thermoactive glue to the top face of the lid plane.
