Thermally insulated housing

A refrigerator, comprising:

• a thermally insulated housing;
• a thermally insulated door attached to said insulated housing;
• said thermally insulated housing and said thermally insulated door each including:
• a substantially vacuum tight outer shell having a given material thickness;
• an at least substantially vacuum tight inner enclosure having a given material thickness and disposed spaced apart from said outer shell;
• a thermal insulation material;
• a connection section having a substantially U-shaped cross section and two limbs including a first limb and a second limb each with a material thickness, said first limb connected to said inner enclosure in a vacuum tight manner and said second limb connected to said outer shell in a vacuum tight fashion, said connection section together with said outer shell and said inner enclosure enclosing an intermediate space filled with said thermal insulation material, said connection section also having an at least substantially vacuum-tight foil-shaped base connecting said two limbs to each other;
• and
• a thickening means having a material thickness disposed at each point of connection between each of said two limbs and one of said outer shell and said inner enclosure, said material thickness of said thickening means plus said material thickness of one of said two limbs substantially equal to said given material thickness of one of said inner enclosure and said outer shell.

An oven muffle for domestic oven, comprising:

• a substantially vacuum tight outer shell having a given material thickness;
• an at least substantially vacuum tight inner enclosure having a given material thickness and disposed spaced apart from said outer shell;
• a thermal insulation material;
• a connection section having a substantially U-shaped cross section and two limbs including a first limb and a second limb each with a material thickness, said first limb connected to said inner enclosure in a vacuum tight manner and said second limb connected to said outer shell in a vacuum tight fashion, said connection section together with said outer shell and said inner enclosure enclosing an intermediate space filled with said thermal insulation material, said connection section also having an at least substantially vacuum-tight foil-shaped base connecting said two limbs to each other;
• and
• a thickening means having a material thickness disposed at each point of connection between each of said two limbs and one of said outer shell and said inner enclosure, said material thickness of said thickening means plus said material thickness of one of said two limbs substantially equal to said given material thickness of one of said inner enclosure and said outer shell.

A thermally insulated wall, comprising:

• a substantially vacuum tight outer shell having a given material thickness;
• an at least substantially vacuum tight inner enclosure having a given material thickness and disposed spaced apart from said outer shell;
• a thermal insulation material;
• a connection section having a substantially U-shaped cross section and two limbs including a first limb and a second limb each with a material thickness, said first limb connected to said inner enclosure in a vacuum tight manner and said second limb connected to said outer shell in a vacuum tight fashion, said connection section together with said outer shell and said inner enclosure enclosing an intermediate space filled with said thermal insulation material, said connection section also having an at least substantially vacuum-tight foil-shaped base connecting said two limbs to each other;
• and
• a thickening device having a material thickness disposed at each point of connection between each of said two limbs and one of said outer shell and said inner enclosure, said material thickness of said thickening device plus said material thickness of one of said two limbs substantially equal to said given material thickness of one of said inner enclosure and said outer shell.
