  • a drain pipe penetrating the thermal insulation of the cooling device in this area provided, which opens into the evaporator dish and which on the inner lining, fixed, for example, using an adhesive or welded connection is.
  • Such a drain line brings on the one hand that it from one Plastic material must be made, which is approximately the chemical and physical properties of the inner container to an at least approximately Process reliability for large-scale production to ensure the types of connection mentioned.
  • the handling of the adhesive, especially its released solvent vapors are problematic, prove when welding the drain pipe to the Inner container the different wall thicknesses between the two as problematic, the wall thickness of the inner container due to its manufacturing process is subject to relatively large fluctuations, but especially in comparison to the the drain pipe is made very thin-walled, whereby the plasticizability both components at the connection point is clearly different, so that it can happen that the thin-walled inner container through the Melting heat supply is damaged.
  • the invention has for its object in a cooling device according to the preamble of claim 1 with simple constructive measures a water drainage to be provided from the collecting trough.
  • the drainage spout formed on the inner container in the area of the collecting trough opens up the possibility of using the water inlet connector on the wall profile to Example in the manner of a plug connection, optionally using sealants put together, making both a technically difficult to handle Gluing process as well as the technically unsafe, if necessary leading to water and foam leaks at the connection point Welding process is avoided.

  • FIG. 1 is a heat-insulating suitable for building a built-in refrigerator Housing 10 shown, which has a step-like indentation on its back 11 for forming a machine room 12, within which a refrigerant compressor 13 and an evaporation tray 14 arranged above it is provided.
  • the housing 10 has an interior divided into two sections 15, in the area above which one of a C-shaped in cross section trained evaporator 16 cooled three-star freezer 17 arranged is below which a cooling compartment 18 is provided, which from one to the Rear wall of the cooling compartment 18 arranged evaporator 19 is cooled.
  • Both that Freezer compartment 17 and the refrigerator compartment 18 are connected by a coherent Deep-drawing of a plastic board-produced inner lining 20 which is a heat insulation layer covered on the outside by an outer covering 21 22 connects and on which heat insulation side in thermally conductive Contact the evaporators 16 and 19 are attached.
  • a collecting trough 23 integrally molded onto the inner lining provided which is used to collect the evaporator during the thawing process of the 19th resulting melt water is used and which in the horizontal section of the step-like Indentation 11 protrudes.
  • the collecting trough 23 has a slope, which on a funnel-like outlet connection piece integrally molded onto the collecting channel 23 24 is aligned, the free end of which is provided with a drain opening 25 is.
  • the drainage nozzle 24 is formed by a chipless cut into the collecting channel 23, produced in cross-section a truncated cone-shaped recess, in the provided with a smaller diameter bottom surface, the drain opening 25 is.
  • the free end of the drain socket provided with the drain opening 25 24 protrudes in one piece into the machine side 12 into the inlet end lining wall profile 26 with molded water inlet spout 27.
  • the Water inlet connector 27, which together with the outlet connector 24 a Melting water from the collecting channel 23 into the evaporation tray 14 Pipe forms, is on its outer contour of a foamed, cuboid-like trained sealing body 30, which has a cylindrical through bore 31 is equipped, the inner diameter of the outer diameter of the Water inlet fitting 27 is adapted.
  • the sealing body 30 has an upper sealing surface 32 and a lower sealing surface 33, of which the upper sealing surface 32 in Installation state of the sealing body 30 on the outer wall of the condensation drainage channel facing it 23 lies sealingly, while the lower one opposite it Sealing surface 33 covers the opening slots 28 sealingly on the heat insulation side and rests on the outside of the wall profile 26 facing the thermal insulation.
