    (54) Device for thermally insulating houshold electrical appliances or parts thereof in which heat is developed, such as the cooking chamber of electric, gas or combination ovens


    (57) A device for thermally insulating a household electrical appliance or a portion thereof in which heat is generated or developed, such as a gas, electric or combination oven or the usual cooking chamber (1) of this latter, said appliance being delimited by walls (2, 3, 4, 5, 6) subjected to radiation as a result of said heat generation or development, said walls (2, 3, 4, 5, 6) having therefore to be thermally insulated. Said device comprises at least two mutually parallel flat elements (7, 10) associated with and slightly spaced-apart from each other on each of said walls (2, 3, 4, 5, 6) to be insulated, said flat elements defining between each other an interspace (11) in which spacer members (12) are provided, said flat elements (7, 10) being of substantially smaller thickness than the walls (2, 3, 4, 5, 6) to be insulated and being formed of high reflectance material.
