Definitions

  • the invention relates to a cooling device.
  • an inner container is arranged in a heat-insulated manner in an outer housing for holding goods to be cooled, in which a plate-shaped one is arranged parallel to the rear wall at a distance Evaporator is arranged.
  • Evaporator is arranged to fasten the evaporator.
  • mutually opposite, outwardly directed grooves are formed in the vertical side walls running away from the rear wall, in which elastically compressible profile strips are inserted.
  • the distance between the vertical side edges from one another is greater than the clear width between the vertical side walls of the inner container, so that when the evaporator is installed in an inclined position, one of its side edges is first placed on a profile strip.
  • the first profile strip By pushing the other side edge further towards the rear wall of the inner container, the first profile strip is compressed, so that the opposite side edge of the evaporator can finally snap into the associated groove or onto the profile strip located therein. With partial decompression of the first profile strip, the opposite side edge of the evaporator then sinks by a corresponding amount into the opposite groove or the profile strip arranged therein, as a result of which the evaporator is fixed in the inner container.
  • the grooves for the mounting of the evaporator form undercuts which are produced when the plastic is removed from the mold Can cause problems with the inner container, the mounting of the evaporator can cause hygienic problems.
  • an evaporator for refrigerant is located in an inner container, which is provided for receiving goods to be cooled, and is arranged at a distance parallel to the vertical rear wall of the inner container.
  • a partition that covers the evaporator from the useful interior of the inner container.
  • This construction requires separate brackets for the evaporator and the partition.
  • the invention has for its object to take measures in a refrigerator that allow attachment of the evaporator with simple means.
  • the evaporator is fixed on fastening strips formed in the corner area between the rear wall and the adjacent side walls.
  • the evaporator then appears as part of the rear wall of the inner container.
  • the fastening strips can, however, also be stepped, so that the side flanks of the step that run into the depth enclose the adjacent peripheral edges of the evaporator.
  • At least the vertical side edges of the evaporator, but preferably also the upper and lower side edges, can be equipped with frame strips, which can optionally also be produced as an overmolded frame. With the frame strips, this evaporator can in turn be fixed on the mounting strips.
  • the frame strips also cover pipe connections provided in the edge region of the evaporator or other irregularities or sharp edges.
  • the evaporator can also be firmly connected on its side facing the useful space of the inner container to a plate, the edge regions of which can be fixed on the fastening strips.
  • the contour of the evaporator can then be designed as desired and in particular can be narrower than the free space between the fastening strips.
  • This plate can consist of a material that is matched in particular to the color of the inner container. However, it can also consist of heat-conducting and heat-storing material, so that the cold storage capacity of the evaporator is increased. As a result, the evaporation pressure in the evaporator is kept at a high value for a long time, which results in an improvement in the cooling efficiency.
  • the evaporator can also have ribs running vertically on its side surface facing the side wall of the inner container, or can be folded, the Folded edges run vertically.
  • the evaporator has horizontal slots in the area of closed shelves arranged in the inner container and to allow cooling air deflectors to engage in the slots, through which the cooled air falling down flows into the space between two shelves, as a result of which in each of these cooling zones own air circulation occurs.
  • An inner container 2 is located in a housing 1 of a refrigerator or freezer, the space between the housing 1 and the inner container 2 being foamed in particular with thermal insulation 3.
  • a plate-shaped evaporator 5 which is connected to a refrigeration circuit via pipes, not shown. From the open side 6 to be closed by a door there are closed shelves 7 at different heights in the usable space for introducing material to be cooled in front of the evaporator 5.
  • mounting strips 9 are provided in the corner area at the transition from the rear wall 4 to the vertical side walls, which are raised above the plane of the rear wall 4 to the opening side 6. These mounting strips 9 are integrally connected to the inner container 2 and have been molded on during its manufacture.
  • the evaporator 5, which is designed as a flat circuit board, is fixed at a distance from the rear wall 4 in the region of its vertical side edges 10 on these vertically extending fastening strips 9.
  • the circuit board of the evaporator 5 is fixed directly to the mounting strips 9.
  • the side edges 10 lie on the side of the fastening strip 9 facing the opening side 6. If the evaporator does not occupy the entire width between the side walls 8, it is expedient to step down the fastening strips so that the Side edges 10 of the evaporator 5 can be sunk into the fastening strip so that the side edges 10 rest on the step flank running parallel to the rear wall 4 and the step flanks directed perpendicularly thereto and pointing into the inner container laterally cover the adjacent peripheral edge of the side edges 10. With an adapted step depth, there is a step-free transition from the evaporator 5 to the subsequent parts of the fastening strips 9 or the side walls 8.
  • the evaporator 5 can also be provided with frame strips which have at least the vertical peripheral edges 10, but preferably also the upper and the Enclose the lower horizontal peripheral edge. These frame strips can be used instead of the vertical peripheral edge 10 for fastening the evaporator 5 to the fastening strips 9.
  • FIGS. 4 and 5 it is also possible, according to FIGS. 4 and 5, to place a plate 11 completely covering the evaporator on the side of the evaporator facing the useful space of the inner container 2, that is to say the shelves 7.
  • This plate 11 preferably overlaps all peripheral edges of the evaporator 5 and is firmly connected to the evaporator 5.
  • the laterally projecting edge zones 12 of the plate 11 can in turn be used for fastening on the fastening strips 9.
  • the plate 11 can in particular be adapted in color to that of the inner container, so that there is an aesthetically pleasing rear closure of the inner container.
  • the plate 11 can in particular consist of plastic if a simple covering and mounting for the evaporator 5 is desired. However, it can also consist of heat-conducting and heat-storing material, in particular sheet steel, if the heat capacity of the evaporator is to be increased.
  • the evaporator can in particular, its side surface facing the rear wall 4 can be provided with elements which enlarge the surface, preferably ribs 13, which run parallel to one another in the vertical direction.
  • the evaporator can also be folded, with the folded edges also extending vertically. The ribs 13 only cover the free part between the fastening strips 9.
  • the evaporator 5 can also be provided with horizontally extending slots which are arranged in the height region of the shelves 7. Cooling air deflectors 15 engage in these slots 14 and lead the cooled air flowing downward in the gap between the rear wall 4 and the evaporator 5 onto the shelves 7. According to FIG. 7, the cooling air deflectors 15 are formed as shapes of the rear wall 4. However, according to FIG. 8, they can also be produced as separate parts which are fixed in the area of the slots 14. It is also possible, however, to incline the flank of the evaporator 5 forming the lower edge of the slot 14 backwards into the gap between the evaporator 5 and the rear wall 4 in order to support a discharge of the cooled air to the respective shelf 7.
