Definitions

  • the invention relates to a refrigerator and / or freezer with at least one Inner container and an outer, this enclosing housing, in which the Gaps between the inner container and those forming the outer housing Walls are foamed with an insulating plastic foam, and with one arranged in the lower area of the rear wall, open to the outside Niche in which at least one motor compressor is arranged.
  • the housing with the inner container in one Foam mold inserted.
  • the niche is thereby created according to a customary method formed that a niche between the side walls in the foam mold limiting cardboard introduced and this by a niche shape corresponding Mold core is supported.
  • Niche has the disadvantage that it is only laterally by the usual housing walls made of sheet metal is limited.
  • CA 12 02 663 A has already suggested that the niche be made from side parts Has injection molded plastic that is spaced from the side walls of the housing are supported, and that the space between the side parts and the side walls is foamed.
  • the inventive Niche part with large thin walls and correspondingly long flow paths of the plastic avoided during injection molding.
  • the niche part just as it were can consist of a niche frame that delimits the edges of the niche be injected at lower pressures in an injection molding machine so that due to the lower spray pressures and better flow behavior a corresponding tool simultaneously two niche frames in an injection molding machine have it made.
  • the manufacture of the niche frame according to the invention is therefore much cheaper than the production of the known trough-shaped niche parts.
  • webs are at least one connecting the transverse profile webs Profile web provided that runs parallel to the side parts.
  • the refrigerator and / or freezer expediently assembled by way of pre-assembly.
  • the niche frame according to the invention can thus be pre-assembled as a stabilizing one Element serve that the sheet metal side walls of the housing with the lower edge areas of the side walls of the niche frame Be connected.
  • the breakthroughs between the profile webs will be then closed by a cardboard box, the ends of which are also the back wall and form the bottom.
  • the pre-assembled housing is then in a Foam mold inserted.
  • the breakthroughs between the profile webs closed by cardboard and then the usual mold core is inserted.
  • the one or more motor compressors are mounted on grids or holding parts Steel rails mounted, the sides of which with the lower end portions of the side panels the niche frame connected, for example screwed.
  • the niche frame 1 consists essentially of the cross-sectional shape the niche corresponding closed side parts 2, 3, by a transverse profile web 4, one the inner upper edge of the Niche frame forming profile web 5 and an inner lower Edge of the niche frame forming profile web 6 are interconnected.
  • the profile web 4 consists, as can best be seen from FIG. 2, of the obtuse angles mutually standing legs 7, 8, the upstanding leg 7 lies approximately in the plane of the rear wall of the refrigerator and / or freezer.
  • the transverse profile web forming the inner upper edge of the niche frame 5 also has an angular profile with legs of approximately the same length.
  • profile web 6 forming the lower rear edge of the niche frame has an angular shape in the manner shown in FIG. 2.
  • the transverse profile webs 4, 5, 6 are through in the central transverse plane of the Niche frame 1 approximately parallel to the side parts 2, 3 profile webs 9, 10 connected to each other so that they are thereby additionally stiffened. Between the profile webs 5, 6 and the central web 9 are in the rear wall of the Niche frame formed large window-like openings 11, 12. In corresponding Way is also the upper side of the niche frame 1 between the Profile webs 4, 5 and the connecting profile web 10 with large window-like Breakthroughs 13, 14 provided.
  • the side parts 2, 3 are, as can best be seen from FIG. 4, also profiled educated. At the lower edge area of the side parts 2, 3 are laterally cantilevered profiled strips 15 formed, the front of which is rounded downwards Form parts 16 sliding feet.
