The pressure-resistant vacuum compartment (2) is subdivided into several vacuum refrigerating compartments (7) the doors (8) of which consist of torsion-resistant frames (11) with large windows (12). It is therefore possible to see into each vacuum compartment (7) without opening its door (8). Ventilation valves (15) are inserted in the glass windows (12) so that the doors (8) can in fact be opened, if necessary. The compartments (7) are individually lit. The compartment doors (8) are sealed with progressive double-lip seals (18). The lower the pressure inside the vacuum refrigerating compartment (7), the more effective are the seals. Serpentine refrigerating pipes (20) incorporated in the bases (21) and, in certain models, in the walls (22) of the individual vacuum refrigerating compartments (7) ensure maximum direct heat flow from the goods to be refrigerated to the refrigerant. Depending on the model, the assembled appliances also have a retractable conventional refrigerating compartment (2) and a conventional freezing compartment (4) which can be operated separately. The refrigerating aggregate (44) and the vacuum pump (24) are mounted on a pull-out frame (45) which is concealed behind the sheet metal ventilation grill (6) in the base of the appliance. |
