Abstract
A washer-extractor-dryer (50), in which a plate heat exchanger (60) is arranged in the outer drum (53). During washing, the plate heat exchanger (60) is located in the washing liquid and, as a result, warms the latter up. During drying of the washed laundry, air is conducted along the outside (63) of the plate heat exchanger (60) and is thereby pre-heated before the air enters the inner drum (52) with the laundry to be dried. A pivotable flap (68) is provided in order to allow liquid to flow along the plate heat exchanger (60) during the washing mode and air to flow along it during the drying mode.
