Definitions

  • the present invention relates to a refrigeration appliance, in particular domestic refrigeration appliance, with a body and interior lighting arranged thereon.
  • the interior lighting should meet a variety of requirements that are not readily compatible with each other.
  • a uniform illumination of the interior of the body over its entire height is desired, even if the light propagation in the interior is affected by refrigerated goods and stored refrigerated goods, on the other should require as little space in the interior and little heat needed for illumination bulbs give to this.
  • a refrigeration device in which light-emitting diodes are used for interior lighting, for example, is off DE 298 14 243 U1 known.
  • This document proposes to accommodate LEDs in recesses of a side wall of the refrigerator body. Proposed mounting locations of the LEDs are on the one hand guide grooves of the side wall, which are provided to receive and guide glass refrigerated goods; Alternatively, large-area recesses may be arranged with light emitting diodes in the amount of a compartment between two guide grooves, or a vertically elongated recess crosses the guide grooves.
  • the light-emitting diodes arranged in the guide grooves couple their light essentially into the refrigerated goods carriers. Although it spreads in these essentially by total reflection, while the light can spread freely over the entire width and depth of the interior, but only little light from the refrigerated goods out into the open, so that the efficiency of the lighting despite a priori good Luminous efficacy of the LEDs remains low.
  • the light emitting diodes housed in the large recesses do not have this disadvantage.
  • Such a disc scatters the light in all directions, not only on the refrigerated goods, but also to the eyes of a user standing in front of it. Since the lenses are at a distance brighter than objects illuminated inside them, it is difficult to avoid dazzling the user.
  • the publication JP 2008 070 080 A shows a refrigerator, wherein on side walls of the refrigerator each have a plurality of light-emitting diodes are arranged.
  • the publication JP 2008 073 153 A shows a refrigerator, wherein on sidewalls each have a plurality of light-emitting diodes are mounted.
  • the publication JP 2008 039 359 A shows a refrigerator, wherein on sidewalls each have a plurality of light-emitting diodes are mounted. The LEDs are covered by a diffuse cover.
  • the publication JP 2006 336 985 A shows a refrigerator with three lighting units, which are each arranged on inner walls of the refrigerator. Here, the LEDs are covered by a diffuse window.
  • the patent KR 100 798 944 B1 discloses a refrigeration device comprising a refrigerator door. On an inner side of the refrigeration appliance door, a lamp arrangement is arranged which comprises a plurality of light-emitting diodes.
  • Object of the present invention is to provide a refrigerator with interior lighting, minimized light losses in the feed into the interior and glare of the user is at least largely excluded.
  • the object is achieved by forming in a cabinet having a refrigerator with an interior surrounded by walls and an open front, in which in a front extending from the front in the depth direction wall of the body is closed by a transparent disc recess, in the at least one light-emitting diode assembly is housed, the disc at least locally is clear and a beam of light emitting diode assembly is completely in the interior.
  • the light cone of the assembly lies completely in the interior, a user standing in front of the body can not directly see a luminous surface of a light-emitting diode, so that direct glare is precluded.
  • An indirect glare on the translucent pane is excluded insofar as it does not diffuse any light in the direction of the viewer where it is clear.
  • the disk is preferably substantially flush with the surface of the wall surrounding the recess so as not to interfere with the use of the interior.
  • the recess is surrounded by a marginally deepened in the wall edge zone into which the disk engages positively. This facilitates the attachment of the disc, since its position is clearly defined by the position of the recesses in its edge zone.
  • the recess is provided on one of the lateral walls of the body, in particular in the vicinity of its open front side. This results in the depth direction of the body seen a particularly uniform illumination of the interior.
  • the light-emitting diode is surrounded by a reflector.
  • the recess in the wall of the body is prismatic, ie triangular in plan view, with a front side of the prism of the open front of the body is adjacent and a rear side is closer to a rear wall of the body.
  • the light emitting diode is arranged on the front side of the prism.
  • recesses are arranged on the front sides of both side walls.
  • the front side of the prism is aligned at a larger angle to the pane than the rear side.
  • the front, near-door side of the prism and the rear side include an obtuse intermediate angle.
  • these multiple light emitting diode assemblies are suitably staggered vertically.
  • the recess is formed as so-called preformed inserts, i. are formed as separate components, and are inserted into correspondingly dimensioned cutouts of the inner lining lining the interior, in particular are inserted such that a introduced into liquid starting components heat insulating material is prevented at the outlet.
  • the recess may extend substantially over the height of the interior, or a plurality of vertically spaced recesses may be provided on the same wall.
  • the plurality of light emitting diode assemblies of a same recess preferably have a main beam directions fanned out vertically to illuminate a portion of the interior, which is above or below one of the recesses.
  • the front and rear sides of the prism-shaped recess include an obtuse intermediate angle.
  • Fig .1 shows a view of a refrigerator according to the invention with a body 1 and a hinged thereto door 2.
  • the interior 3 is divided by refrigerated goods 4 in several subjects.
  • refrigerated goods 4 in several subjects.
  • the side walls 6 of the body 1 several pairs opposite and each closed by a clear glass 7 recesses formed.
  • the recesses are used to accommodate light emitting diodes, which emit in each case to the opposite side wall 6 and in the direction of a rear wall of the body 1.
  • Fig. 2 shows a horizontal section through the front portion of the side walls 6 with the recesses 8 formed therein.
  • the side walls 6 are executed in a conventional manner as hollow foam filled with insulating foam.
  • the recesses 8 each have the shape of an elongated triangle or prism with a front side 9, which forms an angle ⁇ in a range of 60 ° to 75 ° with the glass pane 7 closing the recess 8.
  • the rear side 10 of the recess forms with the glass pane 7 a significantly smaller angle ⁇ in the range of 10 ° to 30 °.
  • a slightly recessed edge zone 11 is formed in the side wall 6, in which the glass sheet 7 is inserted positively.
  • Fig. 2 shows the interior surface facing the glass sheet 7 protruding slightly above the inner surface of the side wall 6;
  • the depth of the edge zone 11 could also be exactly matched to the thickness of the glass pane 7 in order to obtain a completely flat, easily wiped inner surface on the side wall 6.
  • the recess 8 may be formed integrally with the surrounding inner surface of the side wall 6 by deep drawing, preferably in one operation with the skilled in the art familiar manufacture of a one-piece inner surfaces of the side walls, a rear wall and the ceiling and bottom of the body forming inner container by deep drawing ,
  • the use of such - preferably metallic or mirrored - shell is particularly useful if a highly reflective surface, in particular the rear side 10 of the recess 8 is desired.
  • the use of separate from the inner container shell provides the ability to pre-assemble light emitting diode assemblies 12 to this before the shells are installed on the body 1.
  • Light emitting diode assemblies 12 are, as in Fig. 2 and 3 shown, arranged on the front side 9 of the recess 8.
  • a light-emitting diode 16 for shaping its beam is combined with a spherical or parabolic reflector 15 (see FIG Fig. 3 ).
  • the reflector 15 is designed to provide a light cone whose edges in Fig. 2 as dashed lines are drawn.
  • a front edge of the cone of light, designated 13 extends substantially perpendicular to the side walls 6 or at most, as shown in the figure, at a small angle to the front, so that the light of the assembly 12 completely meets the opposite side wall 6.
  • An opposite edge 14 of the light cone impinges on the rear side 10 of the recess and is reflected at this in the depth of the interior space 3.
  • the glass sheet 7 is clear and flat on both surfaces so that it does not form scattering centers.
  • the disk 7 therefore does not appear bright when it is irradiated by the light-emitting diode 16. Also, the rear side 10, as it reflects, does not appear bright to a user standing in front of the device. Glare is thus excluded.
  • Fig. 3 shows a perspective view of an inner container fragment with the recess 8 formed therein and to be mounted in front of the recess 8 glass 7, seen from the rear wall of the interior 3 from.
  • two LED modules 12 are mounted with a central light-emitting diode 16 and a surrounding her, the beam-forming reflector 15.
  • the main beam directions of the two assemblies 12 are substantially horizontal; they may diverge slightly upwards and downwards to evenly illuminate areas of the interior space 3 that are above or below the recess 8.
  • a second embodiment of the invention is in Fig. 4 in one too Fig. 1 shown analog perspective view.
  • the plurality of recesses 8 on each side wall 6 are fused to a recess 17 extending substantially over the entire height of the interior 3.
  • this recess 17 each have a plurality of light emitting diode assemblies of in Fig. 3 shown in a row one above the other on a narrow, front side of the recess.
  • the surrounding reflectors 15 of the beam of a light emitting diode is largely arbitrarily shapeable. While in the arrangement of Fig. 2 the main beam direction of the light-emitting diode assembly 12 is perpendicular to the front side 9 of the recess 8, an arrangement with oblique to the front side 9 oriented main beam direction and smaller opening angle of the beam cone is conceivable. So can for example, as in Fig. 5 shown, the beam cone of the obliquely arranged to the front side 9 LED assembly 12 be dimensioned so that the rear side 10 is illuminated substantially only by light reflected on the glass 7 light and thus does not appear excessively bright, if it does not reflect ,
