Definitions
- the invention relates to a cooling device with a heat-insulated cooling space which can be closed by a door and lined with an inner lining and which is cooled by a defrostable evaporator provided at least on one of its upright walls, below which a collecting melt water accumulating during a defrosting process is also molded onto the inner lining
- a collecting trough is arranged with a drain opening, via which the melt water is discharged into an engine room located at least in sections below the cooling chamber, which is clad at least on its ceiling with a wall profile.
- melt water accumulating during its defrosting process is collected by means of a condensate drainage channel and fed to an evaporator dish, which is arranged in a machine space provided below the cooling space in heat-conducting contact with a compressor arranged there.
- a drain pipe penetrating the thermal insulation of the cooling device in this area is provided at its drain opening, which opens into the evaporator dish and which is fixed to the inner lining, for example by means of an adhesive or welded connection.
- Such a drain line entails, on the one hand, that it must be made of a plastic material which has approximately the chemical and physical properties of the inner container, in order to ensure process reliability that is at least approximately suitable for large-scale production to ensure the connection types mentioned. While the handling of the adhesive, in particular its released solvent vapors, is problematic in the adhesive process, the different wall thicknesses between the two prove to be problematic when the drain pipe is welded to the inner container, although the wall thickness of the inner container is subject to relatively large fluctuations due to its manufacturing process all compared to that of the drain pipe is made very thin-walled, whereby the plasticizability of both components at the connection point is significantly different, so that it can happen that the thin-walled inner container is damaged by the supply of heat.
- the invention has for its object to provide a water drainage from the gutter in a cooling device according to the preamble of claim 1 with simple design measures.
- the wall profile has a water inlet connection which is joined together with an outlet connection molded onto the collecting trough to form a pipeline carrying the melt water.
- the drainage spout molded onto the inner container in the area of the collecting trough opens up the possibility of joining it to the water inlet spout on the wall profile, for example in the manner of a plug-in connection, optionally using sealants, which means that both an adhesive process that is difficult to handle in terms of production technology and the technically unsafe, possibly unsafe welding processes leading to water and foam leaks at the connection point are avoided.
- the water inlet connection surrounds the outlet connection molded onto the collecting channel and the overlap point is provided with a sealant by means of which the water inlet connection and the outlet connection are connected to one another at least in a liquid-tight manner.
- the water inlet connector is also molded onto the wall profile.
- the water inlet connection is designed as a pipe element provided with a bayonet locking device, which can be connected to the wall profile at one of its free ends by means of the bayonet locking device and which has an arrangement arranged over the pipe circumference, the bayonet lock has an upstream elastic sealing lip which, when connected, lies sealingly against the wall profile.
- the water inlet connector is flush with the wall profile on the outlet side and is provided with means for dripping the melt water.
- the flush arrangement of the water inlet socket on the outlet side makes it much easier to install an evaporation tray located above the compressor in the machine room. At the same time, a safe introduction of the melt water into the evaporation bowl is guaranteed.
- the melt water is supplied to the evaporation tray in a particularly targeted manner if, according to a next advantageous embodiment of the object of the invention, it is provided that the means for draining the melt water are designed as drip noses integrally formed on the outlet side of the water inlet nozzle.
- the means for safe drainage of the melt water into the evaporation tray are particularly easy to manufacture, if, according to an alternative embodiment of the subject of the invention, it is provided that the means for draining the melt water from the water inlet nozzle are formed, at least in the vicinity of its outer contour, in sections surrounding opening slots in the wall profile .
- the sealant is designed as a molded part surrounding the water inlet connector on the inflow side, which at least covers the opening slots and covers the area of the joint between the water inlet connector and the outlet connector in a sealing manner.
- the sealant acts as a free end of the water on the inflow side. sereinlaufstutzens arranged around the sealing lip is formed, which surrounds the drain pipe sealing contour-true.
- Such an embodiment ensures the seal at the joint between the water inlet connector and the outlet connector after their joining process.
- a drainage connection is particularly simple and inexpensive to manufacture if, according to a further advantageous embodiment of the object of the invention, it is provided that the drainage connection is designed as a recess which is formed in the collecting trough and has a closed area, into which a drainage opening is machined.
- a drain opening into the recess can be introduced particularly precisely and quickly if, according to a last preferred embodiment of the object of the invention, it is provided that the recess has an embossment in the center of its bottom surface, in which a cutting tool for machining the discharge opening can be centered.
- FIG. 1 shows a heat-insulating housing of a built-in refrigerator with a condensate drainage channel provided on the side of its inner cladding, the outlet connection of which is joined together with a water inlet connection, arranged on a wall profile lining the machine room, in a longitudinal section,
- FIG. 2 shows an enlarged section of the heat-insulating housing in the area of the condensate drainage channel
- Fig. 3 shows an enlarged detail of the wall profile with the water inlet nozzle arranged thereon, surrounded by drainage openings, in a top view
- Fig. 4 is a cut-out sealant, both the connection point between the water inlet connection and the outlet connection as well as the drip openings sealing on the foam side, in a spatial view from the front.
- FIG. 1 shows a heat-insulating housing 10 which is suitable for the construction of a built-in refrigerator and which has a step-like indentation 11 on its rear side for forming a machine room 12, within which a refrigerant compressor 13 and an evaporation tray 14 arranged above it are provided.
- the housing 10 has an interior 15 divided into two sections, in the upper region of which a three-star freezer compartment 17, which is cooled by an evaporator 16 with a C-shaped cross section, is arranged, below which a cooling compartment 18 is provided, which is separated from one another Rear wall of the cooling compartment 18 arranged evaporator 19 is cooled.
- Both the freezer compartment 17 and the refrigerator compartment 18 are lined by a coherent inner lining 20 produced by deep-drawing a plastic board, to which a heat insulation layer 22 covered on the outside by an outer lining 21 connects and to which the evaporators 16 and 19 are attached in heat-conducting contact on the heat insulation side .
- a collecting channel 23 which is integrally formed on the inner lining and serves to collect the melt water which occurs during the defrosting process of the evaporator 19 and which projects into the horizontal section of the step-like indentation 11.
- the collecting trough 23 has a slope, which is aligned with a funnel-like outlet connection piece 24 which is integrally formed on the collecting trough 23 and whose free end is provided with a drain opening 25.
- the drainage connection 24 is produced by a recess which is formed in the collecting channel 23 without cutting and has a truncated cone-like cross-section, and the drainage opening 25 is provided in the bottom surface of which the diameter is reduced.
- the free end of the drain connector 24 provided with the drain opening 25 protrudes in one piece into the machine room 12 into the inlet end lining wall profile 26 with integrally formed water inlet connector 27.
- the water inlet connector 27, which together with the outlet connector 24 forms a pipeline that transfers the melt water from the collecting channel 23 into the evaporation tray 14, is surrounded on its outer contour by a foamed, cuboid-like sealing body 30, which is equipped with a cylindrical through-bore 31, the inside diameter of which is adapted to the outer diameter of the water inlet connector 27.
- the sealing body 30 has an upper sealing surface 32 and a lower sealing surface 33, of which the upper sealing surface 32 lies in the installed state of the sealing body 30 in a sealing manner on the outer wall of the condensation drainage channel 23 facing it, while the lower sealing surface 33 opposite it covers the opening slots 28 in a sealing manner on the heat insulation side and rests on the outside of the wall profile 26 facing the thermal insulation.
