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 Spaces mix the inner container and the one that forms the outer housing Walls are foamed with an insulating plastic foam, and with one arranged in the lower area of the rear wall, towards the outside open 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 through one of the niche shape corresponding core is supported.
  • Niche has the disadvantage that it is only laterally by the usual housing walls made of sheet metal is limited.
  • the object of the invention is therefore a refrigerator and / or freezer at the beginning specified type to create, in which the side walls of the Housing in the area of the niche are backfilled with plastic foam.
  • this object is achieved in that the niche side parts made of injection molded plastic, which 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 side parts placed in the foam mold and then the remaining walls the cardboard covering the niche. After inserting the niche the mold core and closing the mold then the gaps foam between the side panels and the side walls. This foaming in particular also improves sound insulation reached.
  • Another object of the invention is therefore to be made of plastic injection molding existing niche part for a refrigerator and / or freezer at the beginning to create specified type that can be manufactured more cost-effectively than the well-known trough-shaped niche parts made of plastic injection molding.
  • this task with a refrigerator and / or freezer features of claim 1 solved in that the side parts by a upper outer transverse profile web and through the inner upper and profiled crosspieces bounding the inner lower edge of the niche with one another are connected, which are made in one piece with the side parts as an injection molded part are.
  • the niche part according to the invention thus consists of only one niche frame, in which the closed side parts are profiled by transverse Bridges are interconnected.
  • the inventive Niche part with large thin walls and correspondingly long flow paths Plastic avoided during injection molding. Since the niche part of the invention as it were only from a niche frame that bounds the edges of the niche exists, this can be injected at lower pressures in an injection molding machine be so that due to the lower injection pressures and the better Flow behavior with a corresponding tool simultaneously two niche frames have it manufactured in an injection molding machine.
  • the production of the niche frame according to the invention is therefore very much cheaper than that Production of the well-known trough-shaped niche parts.
  • the webs can have at least one profile web connecting the transverse profile webs be provided, which 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 by hanging.
  • the breakthroughs between the Porfilstegen are then closed by a box, the ends of which are the Form the back wall and the floor.
  • the pre-assembled housing is then placed in a foam mold.
  • 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 closed side parts 2, 3 corresponding to the niche through a transverse front profile web 4, 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.
