Definitions

  • the invention relates to a refrigeration appliance and in particular an interior illumination system of such a refrigeration appliance.
  • such an interior illumination has as its light source an incandescent lamp which may be regarded as a light source forming a point, and thus incapable of enabling homogeneous, shadow-free illumination of the internal space.
  • the housings of the aforementioned interior illumination systems are conventionally mounted on the inner skin of a wall of the refrigeration appliance, that is they intrude into the internal space. This has the result that the internal space is narrowed in the vicinity of the mounted interior illumination system. For this reason, the tendency has already been to move towards arranging the housing of this interior illumination system at least partially in a recessed manner within the wall of the refrigeration appliance. However this results in less effective illumination of the internal space.
  • interior illumination systems have recently been proposed which use an elongated light source, for example in the form of a fluorescent tube, which can be mounted vertically on a wall of the refrigeration appliance in order to illuminate a number of compartments within this internal space which are separated from each other by compartment bases.
  • the object of the invention is to create a refrigeration appliance with a light source, in particular an illumination system using an elongated light source, in which the illumination of the internal space can be improved by means of simple structural measures, thus avoiding the disadvantages of the state of the art.
  • the rear wall of the housing to penetrate into one of the insulating walls, the depth of penetration of the rear wall into the insulating wall being at its maximum in the vicinity of the light source and diminishing as the distance from the light source increases, that is towards the rear wall of the body.
  • This form of the rear wall makes it possible to provide for greater width of the interior illumination coupled with negligible loss of insulation volume. Additionally, a large proportion of the light radiated from the light source in a direction more or less parallel to the insulating wall of the housing or towards this wall is scattered on the rear wall of the housing into the internal space.
  • the light source is preferably arranged on an area of the rear wall facing the front side of the refrigeration appliance. It is thereby largely shaded relative to the front side of the appliance, and the danger of a user looking into the internal space being dazzled by the light source is thus avoided.
  • the rear wall is preferably embodied as a reflector.
  • the rear wall of the housing of the internal space illumination system is preferably affixed on the foam side to an inner skin of the insulating wall, filling a window in said inner skin. During foaming of the insulating wall, the rear wall is thus pressed against the inner skin by the foam, and the danger of the foam intruding between the inner skin and the rear wall is minimal.
  • the rear wall of the illumination system housing is embodied in at least 2-part form, with the part facing the light source being longer and located at least partially in the heat insulation, while the other part is arranged on the internal face of the wall.
  • at least one insert groove is preferably embodied on the rear wall.
  • an insert groove open towards the front of the refrigeration appliance is embodied on an edge region of the rear wall adjacent to the front of the refrigeration appliance. This allows the removal of a housing part affixed in this insert groove parallel to the insulating wall towards the front of the refrigeration appliance.
  • a suitable shaping of the compartment bases it is possible to enable the housing part to be removed to the front without it being necessary to remove the compartment bases for this purpose.
  • the light source is preferably free and can be replaced if the housing part is removed.
  • the housing part is further preferably opaque.
  • an insert groove open vertically to the insulating wall is embodied on an edge region of the rear wall adjacent to the rear of the refrigeration appliance.
  • One edge of the window of the inner skin is preferably covered in each case by the housing part inserted into the first and/or second insert groove.
  • FIG. 1 shows a vertical cross section through a refrigeration appliance according to the invention
  • FIG. 2 shows a horizontal cross section through an insulating wall of the refrigeration appliance housing along line II from FIG. 1 .
  • FIG. 1 shows a vertical cross section through a refrigeration appliance according to the invention with a housing comprising a body 1 with side walls 2 and a rear wall 3 , and with a door 4 hung on the body 1 , which as a whole are embodied as hollow bodies foamed with an insulating material.
  • the internal space 5 encompassed by the body 1 and door 4 is divided into a number of compartments 7 , 8 by means of compartment bases 6 .
  • the lowermost compartment 8 contains a pullout box; its depth is reduced compared with that of the compartments 7 to cater for a compressor recess at the rear of the appliance.
  • An interior illumination system 10 extends across the entire height of the compartments 7 on one of the side walls 2 .
  • FIG. 2 shows the structure of the interior illumination system 10 on the basis of a cross section through the insulating side wall 2 at the level of the line II from FIG. 1 .
  • the side wall is constructed in the known manner from a rigid internal skin 11 , which is formed by means of the deep drawing of a plastic plate, and surrounds the entire internal space 5 in one piece, a likewise rigid external skin 12 , and an insulation layer 13 made of expanded polymer material lying between these.
  • a window is cut in the internal skin 11 , which on the foam side is backed with a rear wall 14 of the interior illumination system 10 .
  • the rear wall 14 has a surrounding marginal web 15 , which is fixed around the window on the foam side of the internal skin 11 in a foam-tight manner, for example through the use of adhesive.
  • the depth to which the rear wall 14 penetrates into the insulation layer 13 is at its greatest in the region 16 adjacent to the front of the body 1 ; an inclined wall piece 17 joins the rear of the body 1 , the depth of penetration of which into the insulation layer 13 always diminishes as the distance from an elongated light source 18 arranged on the forward area 16 increases.
  • the inclined wall piece 17 serves as a reflector, being for example mirror-coated, in order to reflect light striking it from the light source 18 with the minimum possible loss onto a translucent diffuser plate 19 which separates the interior illumination system 10 from the internal space 5 .
  • the diffuser plate 19 can be milky opaque or can be provided with imprinted structures which diffract the light in different directions.
  • a further reflecting surface 20 is arranged between the forward area 16 of the rear wall and the light source 18 .
  • a web 21 which engages through the window in the internal skin 11 , with a insert groove 22 open towards the front of the body 1 .
  • a spring 23 of a plastic profile section which forms a further part 24 of the housing of the interior illumination system 10 engages with the insert groove 22 .
  • the housing part 24 is latched in a releasable manner onto a detent tip 25 of the web 21 and has a groove 26 open towards the rear wall 3 of the body (towards the right in FIG. 2 ) with which a spring of the diffuser plate 19 engages.
  • An edge 27 of a compartment base 6 runs a short distance away from the diffuser plate 19 . As may readily be seen, this edge 27 does not prevent the housing part 24 being pulled away towards the front of the body 1 , that is towards the left in the view shown in FIG. 2 . If the housing part 24 is removed, the light source 18 of the interior illumination system is exposed, and can be changed.
  • a groove 28 which is open towards the internal space 5 is formed in the rear wall 14 where the inclined wall part 17 of the rear wall 14 meets the internal skin 11 , into which latches a spring of a housing part 29 likewise manufactured as a profile section which forms a rear fixing for the diffuser plate 19 , likewise by means of a tongue-and-groove connection.
  • the housing part 29 encompasses a wall piece 30 running along the extended inclined wall piece 17 of the rear wall 14 , likewise having a reflective coating.
