Claims6
A refrigerator and/or freezer comprising:
- at least one inner wall defining a cooled interior space,
- at least one outer wall spaced from the at least one inner wall, and
- at least one vacuum insulation body located in the space between the inner and outer walls, the vacuum insulation body comprising:
- at least one vacuum-tight film which surrounds a vacuum region, and
- at least one supporting material arranged in the vacuum region,
- wherein a protective cover for protection of said film is formed by the outer wall,
- wherein a layer of a plastic material is located between the film and the outer wall to level out irregularities between the film and the outer wall, whereby the plastic material between the film and the outer wall is applied in fluid form and curing of the plastic material is effected at the insulation body, and
- wherein the refrigerator and/or freezer does not comprise any foam insulation between the outer and inner walls.
A method of producing a refrigerator and/or freezer having at least one inner wall defining a cooled interior space, at least one outer wall spaced from the at least one inner wall, and at least one vacuum insulation body located in the space between the inner and outer walls, the vacuum insulation body comprising at least one vacuum-tight film which surrounds a vacuum region and which is protected by a protective cover formed by the outer wall, and at least one supporting material arranged in the vacuum region, the method comprising:
- applying a plastic material in fluid form between the film and the outer wall to provide a plastic material layer located between the film and the outer wall to level out irregularities between the film and the outer wall, and
- effecting curing of the plastic material applied in fluid form at the insulation body to produce the refrigerator and/or freezer without any foam insulation between the outer and inner walls.
