• 'Refrigerated furniture, in particular a built-in refrigerator, which consists of an inner refrigerated goods container and a heat-insulating layer made of solid plastic foam, in particular rigid polyurethane foam' ¹¹

if "' - - ■■. "■■■■■

Refrigerated furniture, in particular built-in refrigerated cabinets, have recently consisted of an inner refrigerated goods container made of thermoplastic material, which is particularly easy to process, one in the Usually made of metal outer cladding and one as a means the thermal insulation between foamed-in solid plastic foam, especially rigid polyurethane foam. Is are also designs in the constructive modification of such refrigerators known, in which the rigid plastic foam forming the insulation is foamed onto a metallic supporting structure. Instead of The all-steel outer cladding is impact-resistant on the metal support structure to protect the surface of the plastic foam Fixed sheet metal or plastic panels are provided. There are further designs known in which the mechanical strength and resilience and thus the load-bearing properties of the rigid plastic foam in connection with foamed-in profile strips for holding the sheet metal or plastic plates will. Lately there are built-in refrigerators that do without any surface protection and plastic only on a metallic supporting structure without any cover " is foamed on the outside.

The disadvantage of all of these designs is that they require considerable technical effort in their production, and on the other hand because of the structural design the arrangement of supporting frames for foaming the rigid plastic foam or of profile strips for holding the Sheet metal or plastic panels of the outer cladding create thermal bridges can train.

The innovation is accordingly the task "with existing Surface protection to reduce the manufacturing costs and to avoid such thermal bridges.

In the case of a refrigerated cabinet consisting of an inner refrigerated goods container made of thermoplastic plastic _9, e.g. polystyrene, which is particularly easy to process, and a layer made of solid plastic foam that insulates against heat, in particular rigid polyurethane foam, a surface protection against external influences is, according to the new invention, made of cardboard paper or plastic. Foil existing outer shell provided on the insulating layer, which is firmly connected to this.

The innovation uses the mechanical strength and resilience the heat-insulating plastic layer in cooperation with the cardboard provided as surface protection or plastic film existing outer shell according to the load-bearing properties of these components. As a crucial one This can benefit from the installation of the outer cladding in the known form of sheet metal and plastic plates and the insulating plastic layer supporting scaffolding structures or profile strips can be dispensed with.

The outer shell is made of thermoplastic along with the one Material existing refrigerated goods container using plastics, e.g. based on polyurethane, foamed. Solid polyurethane foam is because of its building properties and especially because of its good adhesion to 'the surfaces of the material with which it comes into contact during lathering suitable material. In connection with it and the refrigerated goods container the outer shell becomes a rigid body.

After a further development of the innovation is the interchangeability of the refrigerated goods container provided. To keep this from the insulating To be able to separate the plastic layer, this is on the inside also covered with a cover made of cardboard paper or plastic film, which is foamed together with the outer cladding will.

In the. Drawings are exemplary embodiments of the furnace and their training shown schematically.

In the pig. 1, a built-in refrigerator is described, according to the innovation consists of an outer shell 1, a refrigerated goods container 2 and a plastic layer 3 foamed in between. For sealing During the foaming process, there is an adhesive bond or at the joints between the outer shell 1 and the refrigerated goods container 2 a strip 4 made of elastic material, such as rubber or the like, is provided. Small fastening elements 7 are located in the insulation 3 foamed in for the refrigeration unit, the door hinges and the base.

In the pig. 2 are the pig in point A ^{1 drawn out.} I the Yerkleungen or strips of elastic material 4 required for the foaming of the plastic at the joints between the outer shell 1 and refrigerated goods container 2 are visible. In the pig. 3, a built-in refrigerator is described according to the further development of the invention, which apart from the outer shell 1, the refrigerated goods container 2 and the plastic layer 3 foamed in between, because of the interchangeability of the cooling container, has an envelope 5 made of cardboard paper or plastic polie arranged between the latter and the plastic layer 3 . In the pig. 4 is point B ^{1 of} the pig. 3 drawn out enlarged.
