Definitions

  • Refrigeration appliance and method for its assembly
  • the present invention relates to a refrigeration device, in particular its assembly.
  • Conventional refrigerators usually have a plastic deep-drawn inner container to which are mounted in the course of installation inside and outside various built-in parts and finally assembled with outer wall elements to form a hollow body.
  • a synthetic resin material is injected, which expands in the cavity to form a heat-insulating foam, which eventually spreads in the entire cavity and fills it.
  • Components which have to be fixed to the inner container for example to prevent them from loosening during further assembly, in particular during the injection and expansion of the insulating material, are conventionally fixed with adhesive tape.
  • This solution is unsatisfactory because it is difficult to automate, and because sometimes chambers are formed between the tape and the inner container, in which the insulation material can not fully penetrate, and can adversely affect the insulation capacity of the finished housing.
  • the object of the invention is to provide a refrigeration device, the housing is mounted in a simple and easy to automate way.
  • the housing part and the further component are preferably fastened to each other by a plastic adhesive.
  • the hot-melt adhesive can be applied to the housing part and / or the further component selectively or in a layer or as a seam, before both are joined together; after both have been placed against each other, it is sufficient to await the solidification of the hot-melt adhesive; further assembly movements, which could be hindered by the tools needed to hold the housing part and / or further component, and which are required when using adhesive tape, omitted here.
  • the housing component is an inner container.
  • the further component can be, in particular, an evaporator, a cable or a pipe for supplying the evaporator or another device mounted on the housing component, or else a backing part which encloses an opening of the housing part, sealed by the hot melt adhesive ,
  • the further component is selectively fixed by the hot-melt adhesive.
  • the invention is preferably applicable to a component which is embedded in an insulating layer of the refrigeration device or adjacent to this.
  • the omission of the conventional fasteners by adhesive tape has the advantage that there is no danger of the formation of pockets that can not be filled satisfactorily by the material of the insulating layer.
  • the latter can be expediently foamed.
  • FIG. 1 is a perspective view of the inner container of a refrigerator and various parts to be mounted thereon according to the present invention
  • FIG. 2 A to E steps of a mounting method according to the invention
  • FIG. 3 is a schematic diagram illustrating a modified mounting method
  • the body of a refrigeration device is composed in a manner known to those skilled in one of a plastic plate, for example made of polystyrene, one-piece deep drawn, shown in Fig. 1 in perspective view inner container 1 and assembled from not shown plates outer skin.
  • the plates of the outer skin, not shown in the figure, are fastened to the inner container 1 by profile elements 2 to 5 joined to a frame enclosing the front side of the inner container 1.
  • Side walls 6 of the inner container 1 are each provided with a plurality of apertures 7, which are provided to receive backing pieces 8. These backing parts 8 are used, for example, to hang in the interior of the inner container 1, not known, the expert known telescopic or refrigerated goods carriers to them.
  • a large-sized opening 9 at an upper rear edge of the inner container 1 and a backing part 10 to be placed there serve, for example, for anchoring an interior lighting or a fan / light combination, not shown, in the inner container 1.
  • the opening 9 is framed in the figure represented by a continuous bead 1 1 of hot melt adhesive material.
  • a likewise continuous extension 12 of the bead extends along the top of the inner container 1 to near its front. While those around the
  • Breakthrough 9 extending caterpillar 11 is provided to when placing the
  • the extension 12 serves for fixing a control or supply cable 13.
  • This cable 13 connects in the fully assembled device, the backing part 10 with an electronic control assembly, which is arranged behind a mounted above the top profile element 2, not shown here control panel.
  • edges of hot melt adhesive material are each provided around the apertures 7 to seal between the backing parts 8 and the inner container 1.
  • FIGS. 2A to E show steps of assembling the backing parts 8.
  • FIG. 2A shows a spray nozzle 14, which pulls a bead 1 1 of hot melt adhesive material around one of the apertures 7 under the control of a digital control unit.
  • the hot melt adhesive material may be mixed with a pressurized gas, such as nitrogen, to expand to a closed cell foam upon exiting the nozzle 14.
  • a voluminous bead 1 1 is obtained with low material usage.
  • a backing member 8 When the bead 1 1 is closed into a ring as shown in FIG. 2B, a backing member 8 can be mounted.
  • the backing part 8 is shown in FIG. 2B for the sake of simplicity as a cup 15 with annular peripheral flange 16, the opening 7 facing the open side and around the open side radially protruding latching hook 17, the interior of which is left empty, it being understood that in the interior of the cup 15 may be any adapted to its intended use in the finished refrigeration contours.
  • hot-melt adhesive material can then be sprayed onto the side of the flange 16 facing away from the side wall 6 and an area of the side wall 6 adjoining the flange 16 so as to produce a plane shown in FIG 2E, the second sealing layer shown
  • the backing piece 8 directly, without prior application of the bead 11, to lock on the side wall 6 or otherwise secure and then spray the sealing layer 20.
  • FIG. 2 shows a partial section of the inner container 1 and of the backing element 10 fastened thereto by a continuous sealing hot glue bead 11.
  • the cable 13 extending from the backing piece 10 to the control assembly is not fixed here by a continuous bead, but the hot melt adhesive is in the form of individual dots 21 along a designated path of the cable 13 distributed to the inner container 1, and the cable 13 is attached by successively in the individual, still hot from the application or as described above reheated and therefore plastic speckles
  • the cable 13 is anchored firmly enough in this way to the inner container 1, to remain safe in place, if in a later assembly step, the limited of the inner container 1 and the plates of the outer skin cavity is foamed with insulating material.
  • FIGS. 4A to D illustrate this in a sequence of schematic sections through the rear wall 27 of the inner container.
  • Fig. 4A shows the rear wall 27 alone.
  • a hot melt adhesive layer 28 is applied to the back wall 27 by brushing or spraying.
  • Fig. 4C is the Evaporator 26 shown in contact with the hot melt adhesive layer 28 on the rear wall. The evaporator may be preheated prior to contacting the layer 28 to melt it.
  • a refrigerant line of the evaporator 26, not shown in the figure, may be attached to the rear wall 27 over part of its length by a continuous hot glue bead such as the extension 12 of FIG. 1 or by individual dots such as the dots 21 of FIG.
