Definitions

  • the invention relates to a cooling device according to the preamble of claim 1.
  • 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 according to the preamble of claim 1, which allow attachment of the evaporator with simple means.
  • the evaporator is fixed to fastening strips which are preferably formed in the corner region 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, which 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 to a plate on its side facing the useful space of the inner container, 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.
  • 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 one 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 especially foamed with thermal insulation 3.
  • the inner container 2 sits parallel to the rear wall 4 with a small distance, for example 10 mm, single-plate 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 goods to be cooled in front of the evaporator 5. If necessary, the evaporator 5 can also be arranged on one of the vertical side walls 8 or the top wall 8.1 of the inner container 2.
  • fastening 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 level of the rear wall 4 to the opening side 6. These mounting strips 9 are preferably 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 in such a way 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.
  • 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 matched 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.
  • its side surface facing the rear wall 4 may be provided with surface-enlarging elements, 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 shelf 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.
  • the cooling air deflectors 15 are designed 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.
