Definitions

  • the invention relates to a refrigerator or freezer with at least one drawer consisting of a plastic shell with a bottom, a rear wall, one Front wall and two side walls.
  • the object of the invention is therefore a drawer for refrigerators or freezers to hand, which in addition to better torsional rigidity has better insulation at the same time.
  • this object is achieved by the features of claim 1. So here by designing the front wall of the drawer in the form of a Multilayer profile or hollow chamber profile, the rigidity can be increased significantly, without the floor and all walls being dimensioned more strongly have to.
  • the upper peripheral edge which is the usual Drawers are designed as a collar, in the form of a multi-layer profile or hollow chamber profile is formed. This already increases the overall rigidity of the Drawer significantly improved without the use of materials and weight Production of the drawer to increase significantly.
  • a corresponding design of the front wall in a drawer for one Fridge at least brings about the improvement in torsional stiffness, though the additional effect of better insulation also plays a subordinate role there plays.
  • the second layer can advantageously be a Multi-layer structure can be formed from styrofoam.
  • the front wall also be designed as a hollow chamber profile, on the one hand by the Hollow chamber cross section stiffening and on the other hand by the Inclusion of air in the hollow chamber a very good thermal insulation is achieved.
  • FIG. 1 shows the freezer section of a fridge / freezer combination 10.
  • drawers 12 and 14 are inserted into corresponding recesses.
  • the freezer is from a laterally pivoted door 16 of the Accessible from the front.
  • the drawers 12 and 14 are injection molded plastic parts. These here drawers 12 and 14 have only a small amount due to the comparatively thin walls Torsional stiffness.
  • in the area of the front wall 18 or 18 'of the drawers 14 and 12 determine a tendency to freeze. This is related to the fact that the door 16 is usually less insulated than that other side surfaces of the freezer compartment.
  • by opening the door 16 and any leaks in the device keep warm air in this area Front wall 18 and 18 'of the drawers 14 and 12 out. Because the drawer front is very cold, the observed icing occurs here.
  • FIG. 4 an embodiment of the invention is shown in the case of a drawer 12 the front wall 18 'is designed as a multilayer profile 20.
  • the drawer is the embodiment in a first method step their floor, their rear wall and their two side walls in the usual Wall thickness has been produced as a plastic injection molded part.
  • the front is foamed in a two-component process known per se and molded onto the remaining parts of the drawer 12.
  • the foamed Two-layer profile 20 gives the entire drawer greater strength.
  • it guarantees that the front is insulated from the freezer compartment door 16.
  • Appropriate trained drawers lead to a smaller one Icing, which could be proven by appropriate tests.
  • the front wall 18 'shown here can also be a hollow chamber profile, which is sprayed by an internal gas pressure such as as such is also known to be formed.
  • an internal gas pressure such as as such is also known to be formed.
  • styrofoam insulation is provided as the second layer.
  • a sectional detail of a drawer side wall 22 is shown, in which a stiffening edge 24 formed as a hollow chamber profile runs all the way round is provided.
  • the torsional stiffness of the Drawer significantly improved without much more material to manufacture the drawer is used.
  • a peripheral edge 24 can also be formed as a plastic multilayer profile become.
  • the two-component process is again suitable for production.
