Refrigerator and/or freezer with double-walled evacuated casing

摘要

The refrigerator/freezer casing is formed in one piece with inner and outer side walls connected by a thinner, narrow front wall of concave shape, the space being evacuated to provide insulation. The sheet of wall material (1) has a first thickness of S1 and a second thickness S2 is formed in a narrow band and made concave. The sheet is folded to form an inner side wall (3) and an outer side wall (4) and a narrow front wall (2) which is curved towards the interior. The space is ultimately evacuated to provide thermal insulation.
