Definitions

  • the invention relates to a drawer for refrigerators or freezers consisting of a plastic shell with a bottom, a rear wall, a front wall and two side walls.
  • the object of the invention is therefore a drawer for refrigerators or freezers to hand, which has a better torsional stiffness.
  • this task is based on a drawer for cooling and Freezers according to the preamble of claim 1 solved in that the side walls, the rear wall and / or the front wall at least partially as Multi-layer or hollow chamber profile are formed. So here by partial Design of the drawer in the form of a multi-layer profile or hollow chamber profile the rigidity can be increased significantly without the floor and all walls are dimensioned stronger.
  • 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.
  • 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.
  • the hollow chamber profiles of the drawers according to the previous design produced by internal gas pressure spraying are produced by internal gas pressure spraying.
  • a method for producing a drawer with the corresponding insulated front front consist in that the drawer is first in a first Step is injected without the front wall and that in a second step the Front wall foamed in a two-component process and on the in first process step molded drawer body is molded.
  • the two-component process for the production of the foamed drawer body already known as such in plastics processing.
  • FIG. 1 shows the freezer section of a fridge / freezer combination 10.
  • 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.
  • 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 embodiment is the drawer with 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.
  • the front is insulated from the freezer 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.
  • FIG. 2 and 3 an embodiment variant of the invention is shown, which is only busy with the task of improving the strength of the drawer.
  • a sectional detail of a drawer side wall 22, at a circumferential stiffening edge 24 formed as a hollow chamber profile is provided is.
  • 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.
