ABSTRACT:
A heating cabinet includes a fan (24) by means of which air is drawn out of the inner housing into an air chamber (22). From the air chamber (22) the air is directed through a preheating chamber (28) of U-shaped cross-section, comprising a heating element (34), enclosing the inner housing, and is directed back into the usable space through apertures (36) in the side walls (16) of the inner housing. Air guidance plates (38) are attached externally on the side walls (16) which compel the air to flow along the entire length of the heating element (34) before it can pass out through the apertures (36). In this manner, temperature differences between the air passing through the different apertures (36) are avoided and localized temperature variations in the usable space are minimized.
