Definitions

  • Refrigeration device with door air duct
  • the present invention relates to a refrigerator with a body in which at least one storage chamber and an evaporator chamber are partitioned, and a door, wherein in a wall of the evaporator chamber, a first inlet opening facing the door is formed and extending in the door first air duct on the first inlet opening opens.
  • Such an air duct may be required, in particular, in refrigeration appliances with forced circulation in order to ensure a satisfactory exchange of air between the evaporator chamber and all storage chambers or all areas of a storage chamber.
  • an outlet opening of the air duct with the door closed is placed directly opposite the inlet opening and close and substantially close to this.
  • Object of the present invention is to provide a refrigeration device of the type specified, the simple means a low-loss, against any shifts ensures tolerant passage of air from the first air passage into the first inlet opening between the door and the body of the refrigerator.
  • the object is achieved in that in a refrigerator with a body in which at least one storage chamber and an evaporator chamber are divided, and a door, wherein in a wall of the evaporator chamber, a door facing the first inlet opening is formed and extending in the door first air passage has an outlet opening which is the first inlet opening separated by a gap, a flow guide from an edge of the first inlet opening tapers to the door and the air duct is formed to eject an obliquely directed against the guide surface airflow. It turns out that such an air flow, probably due to the Coanda effect, largely lossless and without swirling with dormant air of the gap to a significant extent, is able to flow along this guide surface along. Since, when the air circulates in the interior of the refrigerator in a closed path, the air flow rate of the inlet opening can not be smaller than that of the air duct, the air flow discharged from the air duct is substantially completely absorbed by the inlet opening.
  • this expediently has larger dimensions than the outlet opening.
  • a guide plate parallel to the flow guide surface is preferably arranged in the first inlet opening.
  • the flow guide is preferably part of a ceiling of the body.
  • the first inlet opening opens onto a second air channel extending in the wall between a second inlet opening open to the bearing chamber and the evaporator chamber.
  • An air flow in this channel which may be driven by a blower, for example, to convey cold air from the evaporator chamber into the storage chambers, generates at the location of the first inlet opening after the Bernoulli law, a negative pressure, so that the emerging from the first air duct in the door air is efficiently sucked into the second air duct.
  • the second air channel is also expedient for the second air channel to be curved at the level of the first inlet opening and for the first inlet opening to open on a convex side of the second air channel. If the air circuit passing through the first air passage is interrupted and no air from the first air passage into the first inlet port, a flowing between the second inlet opening of the evaporator chamber air flow can follow the course of the second air duct by Coanda effect loss.
  • At least one curved deflecting plate is preferably provided in an outlet opening of the first air duct opposite the first inlet opening.
  • the above-defined invention is particularly advantageously applicable to a refrigerator whose body has a first storage chamber adjacent to the evaporator chamber and a second storage chamber remote from the evaporator chamber, and the first air duct in the door leads from the second storage chamber past the first storage chamber to the evaporator chamber.

  • Fig. 3 is an analogous to Fig. 1 section according to a second embodiment of the present invention.
  • Fig. 1 shows in section the upper edge region of a refrigerator door 1 and the front edge of a ceiling 2 of the refrigerator body.
  • the door 1 has in a conventional manner an outer wall 3 made of sheet metal, an inner wall 4 made of plastic and an enclosed between the walls filling 5 of insulating foam material.
  • An air duct 6 extends in the door 1 between the inner wall 4 and the filling 5 of an inlet opening, not shown, at the level of a lower of two storage chambers of the refrigerator to an outlet opening 7 at an upper edge of the door.
  • the air channel 6 is formed on the majority of its length by an extrusion profile 8; on the upper end of the extrusion profile 8, an injection-molded Umlenkstutzen 9 is attached.
  • An upper end of the Umlenkstutzens 9 extends through an opening of the inner wall 4 and is latched to an externally plugged mask 10.
  • the insulation material filling 5 facing wall of the Umlenkstutzens 9 is curved in the upper quarter of a quarter circle; concentric with this curvature, a baffle plate 11 extends over the entire width of the outlet opening 7.

  • the evaporator chamber 14 has only a single inlet opening 15, which lies opposite the outlet opening 7.

Abstract

L'invention concerne un appareil de réfrigération comprenant un corps (2), dans lequel se trouvent au moins une chambre de stockage (13,23) séparée d'une chambre d'évaporation (14), et une porte (1). Dans une paroi (12) de la chambre d'évaporation (14) est formée une première ouverture d'entrée (15) orientée vers la porte (1) et un premier conduit d'air (6) s'étendant dans la porte (1) est pourvu d'une ouverture de sortie (7) qui se trouve face à la première ouverture d'entrée (15) dont elle est séparée par un intervalle. Selon l'invention, une surface conductrice d'écoulement (2) s'étend d'un bord de la première ouverture d'entrée (15) vers la porte (1), et le premier conduit d'air (6) est formé pour expulser un flux d'air orienté à l'oblique contre la surface conductrice d'écoulement (2).
