Definitions

  • the present invention relates to a refrigeration appliance, in particular a domestic refrigeration appliance, in which a blower for homogenizing the temperature distribution is provided in a storage compartment of the refrigeration appliance.
  • Object of the present invention is to provide a refrigeration device that achieves good homogeneity of the temperature distribution in the storage compartment with simple means.
  • the object is achieved by providing in a refrigerator, in particular domestic refrigeration appliance, with at least one accessible through a door storage compartment, on the rear wall of an evaporator is provided which is acted upon by a fan with air over an air guide is directed towards the door, the air duct is formed as the evaporator downstream downstream distribution channel having an increasing from its Einströmöffung to its door-facing exhaust opening towards the width.
  • the width of the distribution channel towards the exhaust opening increases at least substantially continuously. This can be used as lateral boundary walls for the distribution channel rectilinear side walls.
  • the width of the distributor channel increases at least approximately equally on both sides. As a result, a particularly simple production of the distribution channel is possible.
  • the distribution channel at a downstream end fills the entire width of the storage compartment.
  • divergent guide ribs are arranged in the distribution channel.
  • the distribution channel expediently extends over a wall of the storage compartment adjoining the rear wall.
  • the distribution channel preferably extends to a front edge of the adjacent wall.
  • the adjacent wall will be a ceiling of the storage compartment.
  • the distribution channel is expediently delimited by a shell which covers the wall adjacent to the rear wall.
  • the adjacent wall preferably has at its front edge a web projecting into the storage compartment, and an elongate exit opening of the channel is bounded on one side by the web and on the other by a front edge of the shell.
  • the shell may be attached to the adjacent wall by means of fingers projecting beyond its front edge. These are generally easily accessible and can be solved when it is necessary to disassemble the bowl and access the blower it is hiding.
  • the blower In order for the blower can effectively suck cold air, the blower is preferably preceded by an intake gap, which is bounded on one side by the evaporator.
  • a side of the suction gap opposite the evaporator may be formed by a rear wall of a drawer placed in the storage compartment.
  • the storage compartment is a zero-degree compartment in a combination refrigerator.
  • FIG. 1 shows a schematic section through the lower region of a combination refrigeration device according to the invention.
  • Fig. 2 is a schematic plan view of a distribution channel of the refrigerator limiting shell.
  • Fig. 1 shows a schematic section through the body 1 and door 2 of a refrigerator according to the invention.
  • the device has a in the figure only partially shown normal refrigeration compartment 3 and below this, separated by a heat-insulating partition 4 of the body 1, a zero-degree compartment 5.
  • a vertical suction gap 8 extends - A -
  • telescopic rails extendable guided drawers 9, 10.
  • the upper of these drawers, 9, is recessed at its upper rear edge a piece to make room for a Axial blower 1 1 to create, which is mounted below the intermediate wall 4.
  • a flat shell 12 made of plastic separates the installation space of the axial fan 11 and each one extending below the intermediate wall 4 along distribution channel 13 from the zero-degree compartment 5 from.
  • An outlet opening 14 between a front edge of the shell 12 and a downwardly projecting at the front edge of the intermediate wall 4 flat web 15 extends over the entire width of the tray 5.
  • An oblique Anström tone 16 at the back of the web 15 deflects out of the channel 13 Cold air down. Part of the cold air is distributed in the upper drawer 9; the remainder flows down between the front sides of the drawers 9, 10 and the door 2 and is distributed on the underlying drawer 10 and a horizontal gap 17 kept between the bottom of the drawer 10 and the bottom of the compartment 5, through which the air is returned to Rear wall gap 8 passes.
  • Fig. 2 shows a plan view of the shell 12.
  • the shell 12 is on most of its surface substantially flat, except for a central trough 18 at the rear edge, which is shaped to receive the blower 1 1.
  • a cutout 19 of shallow depth is formed at the rear edge of the shell 12, which together with the rear wall 6 delimits a suction slot through which the blower 11 draws cold air from the gap 8.
  • the distribution channel 13 is subdivided by a plurality of divergent guide ribs 22.

Abstract

L'invention concerne un appareil frigorifique comportant un évaporateur disposé sur une paroi arrière d'un compartiment de stockage, et une soufflerie axiale disposée dans un coin entre la paroi arrière et une paroi adjacente, dont l'axe est essentiellement parallèle à la paroi adjacente. Un canal de distributeur s'étendant le long de la paroi adjacente, en aval de la soufflerie axiale, présente une largeur qui augmente dans le sens du courant d'air produit par la soufflerie axiale.
