Definitions

  • the present invention relates to a housing component for a refrigeration appliance, in particular for a household refrigerating appliance, which comprises at least one vacuum insulation panel.
  • a housing component is made DE 103 42 859 A1 known.
  • a vacuum insulation panel is generally composed of a highly diffusion-proof plastic film and a porous filler such as silica, zeolite, glass fiber, polyurethane foam or the like, which is airtightly sheathed by the film and kept under a negative pressure.
  • Vacuum insulation panels have excellent insulation properties at low wall thickness, but are expensive due to their complex production, and they are difficult to handle in refrigeration equipment, as they do not fit seamlessly into a prefabricated hollow-walled housing in contrast to the polyurethane foam conventionally used.
  • the object of the invention is therefore to provide a housing component for a refrigeration device with at least one vacuum insulation panel, which is simple and inexpensive to produce, and to provide a method for their preparation.
  • the object is achieved by enclosing a case component with a shell which encloses an insulating material-containing cavity, wherein the shell Vacuum insulation panel is attached, at least one surface of the shell has a weldable plastic to which the vacuum insulation panel is welded.
  • said shell surface is an interior cavity-facing surface, and the vacuum insulation panel forms at least a portion of the insulation material contained in the cavity.
  • the vacuum insulation panel is protected by the shell from damage.
  • a foam layer, in which the vacuum insulation panel is embedded, can expediently completely fill the cavity.
  • a release layer may be provided between the vacuum insulation panel and the foam layer to prevent the foam from adhering to the surface of the vacuum insulation panel, thus allowing recovery of the costly vacuum insulation panel when recycling the housing.
  • the separating layer may expediently be formed as a film.
  • the embedding foam layer can adhere to this without it itself adhering to the vacuum insulation panel.
  • the release layer In order to hold the release layer in place at least during assembly of the housing component, it may be conveniently attached to a portion of the shell projecting beyond an edge of the vacuum insulation panel.
  • the vacuum insulation panel may expediently be arranged on an outer side of the shell facing away from the bearing chamber. This is particularly useful when the inside of the shell is structured three-dimensionally, for example, to allow the attachment of internals in the housing, and the attachment of the generally planar plate-shaped vacuum insulation panel on the inside would give difficult to fill with foam cavities.
  • the inside of the shell is sufficiently flat, however, it is appropriate to attach the vacuum insulation panel directly to her, since the vacuum insulation panel then Generally, it can have smaller edge lengths than an outside fastened and therefore cheaper.
  • the weldable plastic advantageously forms a layer on a surface of the sheet.
  • the weldable plastic may be provided as a layer on the surface of at least a portion of the shell-forming composite material.
  • the shell consists at least in places of one layer of the weldable plastic.
  • the weldable plastic may in particular be PET, PE, PP, PA, PS, EVA or ABS, with PS and ABS being particularly preferred.
  • induction welding high frequency welding, microwave welding, infrared welding and vibration welding are particularly suitable, and among them, induction and vibration welding are particularly preferable.
  • Other techniques such as hot plate welding, hot gas welding or laser welding are less convenient because it is difficult to evenly heat a large contact area between the shell and the vacuum insulation panel.
  • Fig. 1 shows a horizontal cross section through a housing of a household refrigerator according to a first embodiment of the invention.
  • the housing comprises a body 1 and a hinged thereto door 2, which surround a storage chamber 3 for refrigerated goods.
  • Both housing components, the body 1 and the door 2 are each initially formed as a hollow body with an assembled from several parts, surrounding an inner cavity shell.
  • the shell comprises both the body 1 and the door 2 a deep-drawn from plastic, adjacent to the storage chamber 3 inner skin 4 and an outer skin 5, which may be integrally formed or joined together from several parts.
  • the outer skin 5 or its parts can be formed from sheet metal, from the same plastic as the inner skin 4 or from multilayer plastic composite material.
  • Inner and outer skin of a housing part are connected to each other at the level of a arranged in a known manner between the body 1 and door 2 magnetic seal 6.
  • the outer skin 5 is provided on its inner cavity of the body 1 and the door 2 facing surface with a weldable plastic layer of PS (polystyrene) in particular HIPS (High Impact PS) or ABS (acyl-butadiene-styrene).
  • PS polystyrene
  • HIPS High Impact PS
  • ABS acyl-butadiene-styrene
  • a vacuum insulation panel 7 is fixed by induction welding, high-frequency welding, microwave welding, infrared welding or vibration welding.
  • the dimensions of the vacuum insulation panel 7 are smaller than those of the inner cavity obtained when the outer skin 5 and the inner skin 4 are bonded together after welding the vacuum insulation panel 7.
  • This inner cavity 8 is then completely filled by ejecting and expanding polyurethane.
  • the vacuum insulation panels 7 ensure a highly effective insulation of the storage chamber 3 on almost its entire surface, with the exception of columns 9, 10 between the body 1 and door 2 or at the edges of the body 1, where the vacuum insulation panels 7 of side walls and rear wall of the body. 1 or in Fig. Not shown, in a corresponding manner in The ceiling and bottom of the body 1 inserted vacuum insulation panels should not touch directly to allow passage of the polyurethane between the panels 7 and its full spread over the entire space 8.
  • the inner skin 4 homogeneously monolayer of PS, ABS or another weldable plastic molded, in particular deep-drawn, it is also possible to weld to their vacuum insulation panels 7, as in Fig. 2 shown.
  • the inner skin 4 when a Vakuumisolationspaneel 7 is to be welded to her, composed of individual plates, for example made of sheet metal or plastic composite material, since these plates are easier to implement required for a large-scale welding of the vacuum insulation panels 7 flatness.
  • the outer skin 5 here have the plates of the inner skin 4 a the space 8 facing coating of a weldable plastic.
  • a coldwall evaporator 11 is arranged in the space 8 in contact with the inner skin 4, there eliminates the Vakuumisolationspaneel, or it is as in Fig. 1 shown arranged on the outer skin 5.
  • Fig. 3 shows an enlarged detail of a vacuum insulation panel 7 and a shell 12 to which it is welded, wherein the shown section of the shell 12 both a Section of the inner skin 4 and the outer skin 5 may be.
  • the vacuum insulation panel 7 comprises a block 13 of porous material and a multilayer film 14 which surrounds the block 13 airtight.
  • the film 14 has a multilayer structure with a central barrier layer 15 of highly diffusion-tight plastic such as PVdC (polyvinylidene chloride) or EVOH (ethylene vinyl alcohol) between outer and inner protective layers 16, 17, which in turn may be constructed in one or more layers.
  • the outer protective layer 17 is fused by welding over a large area with a layer 18 of ABS or HIPS on the inner surface of the shell 12th
  • a release film 19 extends between the vacuum insulation panels 7 and the polyurethane foam filling the gap 8.
  • the release film 19 is on the vacuum insulation panel 7 loose or at most easily mounted on and is left under the panel 7 at the weld.
  • the release film 19 may be glued to the shell 12 or fixed by adhesion like a known food cling film.
  • the release liner 19 allows for quick and clean separation of the polyurethane foam from the vacuum insulation panel 7. If the weld between the protective layer 17 of the panel and the layer 18 of the shell 12 is not too intimate, the shell can be withdrawn from the panel 7 again, and the panel 7 can be re-installed.
