Definitions

  • the invention relates to a method for producing a wall for a household refrigerating appliance, in which a wall part made of plastic is formed, and a raw material provided ready for the final shape of the wall part is deformed. Furthermore, the invention relates to a wall for a household refrigerator, which is manufactured according to the method, as well as a household refrigerator with such a wall. From WO 2012/031885 A2, a housing for a household refrigerator is known. An inner shell of the housing, which delimits an insulation material pack to an interior of the domestic refrigerator, has a multilayer structure. This layer structure comprises two carrier layers, between which there is a barrier layer or barrier layer, which in turn is connected on both sides with an adhesion-promoting layer, which adjoin the carrier layers.
  • Inner containers of refrigerators or interior doors of refrigerators are typically made of known plastics such as ABS (acrylonitrile-butadiene-styrene) or polystyrene, especially HIPS.

  • this inner shell of the known vacuum door is formed of a multilayer plastic material which is brought by deep drawing in the desired shape.
  • a gas diffusion inhibiting barrier layer is introduced in this multilayer material, which is provided as a blank for the subsequent deep drawing.
  • the main reason for the multi-layered layer construction is the necessity that the plastic inner door and thus this inner part must fulfill different properties. Among other things, it must be a gastight barrier, so that the vacuum in the door is not lost.
  • a wall part in particular a part of a vacuum body, in particular an inner part, of the wall part is formed from plastic.
  • a raw material provided becomes the final shape of the wall part shaped.
  • An essential idea of the invention lies in the fact that in the manufacturing process after this molding of the raw material to the basic final shape of the wall part at least one surface side of this then endgeformten wall part is provided with a gas-tight barrier layer and thus this gas-tight barrier layer is applied to at least one surface side at least partially.
  • Such a configuration of a production method makes it possible that the raw material can be formed in its basic production and provision without such a barrier layer and therefore also the subsequent shaping of the inner part, which is finally formed from the raw material, is simpler. Because it can be achieved in this context in particular a more complex shape of the inner part, since the raw material can be easily deformed without this already introduced barrier layer. Moreover, it is also possible by such a procedure according to the invention in the production that the then already final molded wall part can be provided very site-specific and / or material-specific with the barrier layer.

It is also possible that the barrier layer is applied as a lacquer and is thus painted on the surface side. It can also be provided that the barrier layer has particles which at least minimize gas diffusion. such Particles may be, for example, metal particles or ceramic particles or glass particles or other particles of a gas-tight material.
  • the barrier layer is particle-free and no additional materials and / or components are introduced into a carrier material.

  • the inner part is produced by a deep-drawing process.

Due to the embodiment according to the invention or an advantageous embodiment thereof, this is now also possible in a deep-drawing process.

  • the invention thus makes it possible that conventional production processes, such as deep-drawing or injection molding, do not have to be changed, yet increased variability and flexibility prevails in the shaping for producing the inner part and, in a downstream process, the gas-tight property of the wall, in particular of the vacuum door. is formed.
  • a substance which brings about the gas-tight property is applied in a planar manner to at least one surface side of this inner part. It can also be provided that this gas-tight barrier layer is applied to the outer shell or in addition to the outer shell of the vacuum body.

This then succeeds in particular at the points of the inner part, which has a complex shape. An undesirable dilution of the barrier layer, which may result, for example, during deformation during a deep drawing process, is then prevented here.
  • Last but not least, such a subsequent process step, in which the barrier layer is then applied after the final shaping of the inner part can achieve greater flexibility with regard to the design of the barrier layer in terms of thickness and / or material composition and / or local attachment. Also, such a downstream application step in which this barrier layer is applied to the final molded base body, in particular the inner part, is possible independently of the previous specific method for final shaping of the base body.
