Definitions

  • the invention relates to a refrigerator, in particular a refrigerator and / or freezer, comprising a housing which has a ceiling wall, a bottom wall, side walls and a rear wall as outer walls and a door, an interior space located in the housing, which is enclosed by inner walls, and a front frame for thermally decoupling the inner walls from the outer walls.
  • refrigerators with housing structures are known in which between the metallic inner walls, which surround a housing located in the interior, and the metallic outer walls of the housing, a plastic front frame is used to avoid a direct thermal bridge between the inner and outer walls.
  • the problem of heat transfer arises in particular when the inner walls and the outer walls are made of metal, which has a high thermal conductivity.
  • the plastic front frame serves to worsen the direct heat conduction between the inner walls and the outer walls.
  • the housing in the interior between the inner and outer walls is usually filled with an insulating foam, with which a heat input from the outside is reduced in the interior.
  • the insulation foams commonly used are not able to completely prevent the heat input, so that usually the side walls of the refrigerator are slightly cooler than the environment and the rear wall.
  • the rear wall of the refrigerator is usually usually warmer than the side walls and the environment, as disposed on the rear wall of the condenser, which gives off heat to the environment.
  • the front of the refrigerator is warmer than the side walls, since ambient air can circulate well here and thus can warm up the front.
  • US-A-2 625 291 discloses the construction of a refrigerator with strips to close a cavity between walls of a body of the refrigerator.
  • US-A-2 582 862 discloses a refrigerator with an inner and an outer housing which are interconnected.
  • the refrigerator according to the invention in particular refrigerator and / or freezer, comprises a housing which has a ceiling wall, a bottom wall, side walls and a rear wall as outer walls and a door.
  • the refrigerator further comprises an interior space located within the enclosure enclosed by interior walls and a front frame for thermally decoupling the interior walls from the exterior walls, the side walls being thermally isolated from the other walls by a further isolation bar.
  • the insulating strip is arranged between the side walls and the front frame, and the insulating strip connects the side walls with the front frame.
  • the front frame is usually made of plastic and serves to interrupt the heat conduction path along the inner walls to the outer walls. This is particularly important if the inner walls or the outer walls are made of a thermally highly conductive material, such. Metal are made.
  • the insulating strip serves to reduce the heat conduction along or within the walls of the housing.
  • the side walls are thermally insulated from the ceiling wall, from the bottom wall, from the rear wall and from the inner walls.
  • the side walls are thermally decoupled from the other outer walls as well as from the inner walls.
  • the isolation bar presents a further heat conduction resistance, whereby a temperature compensation on the housing difficult and thus a heat input into the interior of the housing is reduced.
  • a heat transfer is reduced by warmer places, such as from the rear wall or from the warmer floor or ceiling walls. Also can be reduced by the insulating strip heat input from the front frame in the side walls.
  • the side walls are better thermally decoupled, which is particularly advantageous when the refrigerator is installed as a built-in appliance in a furniture niche, in which a gap (eg a thin gap) between the side walls and the furniture niche can be used as an additional insulation layer.
  • This gap or furniture furniture can thus be used as further insulation.
  • the insulating strip is in particular made of a thermally poorly conductive material, such. Made of plastic.
  • the insulating strips are used in particular to deteriorate the heat conduction along the outer surface of the housing and to make it difficult to compensate for temperature between different locations on the outer surfaces of the housing.
  • the insulating strip has a first receiving element, in particular a groove, for receiving the side walls, the top wall or the bottom wall. With the help of the first receiving element, a mechanically strong connection between the insulating strip and the respective wall is produced.
  • the insulating strip has a second receiving element, in particular a groove, for receiving the front frame.
  • the second receiving element is particularly advantageous if the insulating strip between the side wall and the front frame is arranged. With the help of the second receiving element, a mechanically strong connection between the front frame and the insulating strip is produced, whereby the front frame is mechanically stabilized.
  • the insulating strip has a third receiving element, in particular a clip element, for receiving a reinforcing frame. Due to the reinforcement frame, the insulation strip is mechanically reinforced.
  • the reinforcing frame can contribute to the stabilization of a door-side region of the housing, which is particularly advantageous when large and heavy doors are to be fastened to the refrigeration device.
  • the reinforcing frame is provided in particular for reinforcing the housing and on the reinforcing frame, the door is hinged. With the aid of the reinforcement frame, large forces introduced via a heavy or heavily laden door can be transmitted evenly to the housing.
  • the reinforcing frame is made in particular of metal, preferably of steel. Since the reinforcement frame is connected to the warm hinges, it usually has a higher temperature than the side walls. With the help of the insulating strip, the reinforcement frame can be thermally decoupled from the cooler side walls.
  • the housing can be made mechanically (warp) stiffer and thermally better insulating.
  • this makes it possible to make the front frame simpler, which had to be designed comparatively complicated in the prior art refrigerators, since it at least partially zukam a mechanically stabilizing function.
  • the support and / or spacer ribs represent an advantageous structural measure to further reduce the heat conduction.
  • a heat conduction distance between the side walls and the other walls or side walls and the reinforcing frame can be extended by the use of the support and / or spacer ribs.
  • the extension of the heat conduction path reduces the energy input from outside to inside the refrigeration device.
  • the heat conduction path is extended by at least 50%, in particular by at least 100%, preferably by at least 200%, whereby the heat conduction performance is reduced by a corresponding factor.
  • the insulating strip sealing lamella on to seal the housing during its expansion against leakage of insulating foam to the outside.
  • the insulating strip can thus also be used to seal the housing during the foaming in such a way that no liquid insulating foam escapes to the outside.
  • the assembly of the refrigeration device can be simplified. So far, it has often been necessary to connect the sides and the other walls by means of sealing tongue and groove connections, which resulted in a considerable installation effort.
  • the housing compartment can be foamed by the front of the housing is placed down ("bell") and the rear wall is placed on the side walls provided on the insulating strips, which solely by placing the rear wall on the slats of the Insulation strip a sufficient tightness is achieved, so that foaming of the housing can be relatively easily realized.
  • the use of sealing fins can thus make the process for producing the refrigerating appliance, in particular for foaming the housing, much simpler.
