Abstract
A heat-insulating housing, such as for an oven chamber of a household oven or a refrigeration chamber of a household refrigerating appliance, includes at least one working space which is surrounded by housing walls and can be closed by a door. The housing walls are formed from two substantially dimensionally rigid housing shells which are at a spacing from each other and together substantially enclose an intermediate space that can be evacuated and is filled with heat-insulating material which can be introduced loosely.
Claims21
A heat-insulating housing based on a vacuum insulation, comprising:
- housing walls formed of two mutually spaced apart rigid boundary walls substantially enclosing an interstice;
- at least one door enclosing at least one useful housing space along with said housing walls;
- and
- slabs of pressure-resistant, open-celled, evacuatable heat insulation material in a final chemical state introduced loose into said interstice for filling said interstice, said pressure-resistant, open-celled, evacuatable heat insulation material being in direct contact with said rigid boundary walls, and wherein gas present in said pressure-resistant, open-celled, evacuatable heat insulation material is evacuated after said slabs are introduced into said interstice for providing heat insulation.
An oven chamber of a household oven, comprising:
- a vacuum-insulated heat-insulating housing including:
- housing walls formed of two mutually spaced apart rigid boundary walls substantially enclosing an interstice;
- at least one door enclosing at least one useful oven housing space along with said housing walls;
- and
- slabs of pressure-resistant, open-celled, evacuatable heat insulation material in a final chemical state to be introduced loose into said interstice for filling said interstice, said pressure-resistant, open-celled, evacuatable heat insulation material being in direct contact with said rigid boundary walls, and wherein gas present in said pressure-resistant, open-celled, evacuatable heat insulation material is evacuated after said slabs are introduced into said interstice for providing heat insulation.
A refrigeration chamber of a household refrigerating appliance, comprising:
- a vacuum-insulated housing including:
- housing walls formed of two mutually spaced apart rigid boundary walls substantially enclosing an interstice;
- at least one door enclosing at least one useful refrigeration housing space along with said housing walls;
- and
- slabs of pressure-resistant, open-celled, evacuatable heat insulation material in a final chemical state to be introduced loose into said interstice for filling said interstice, said pressure-resistant, open-celled, evacuatable heat insulation material being in direct contact with said rigid boundary walls, and wherein gas present in said pressure-resistant, open-celled, evacuatable heat insulation material is evacuated after said slabs are introduced into said interstice for providing heat insulation.
