  • the washer-dryer 1 For drying laundry in the drum 2, the washer-dryer 1 has a process air duct 22, which extends from an inlet 23 on the tub 2 to an outlet 24 on the tub 2. In the process air channel 22, the air used for drying is conducted in a substantially closed circuit enclosing the tub 2. In the process air duct 22, an air-air heat exchanger 25, a fan 6 and an electric heater 5 are arranged. By means of the electric heater 5, the air used for drying (process air) is heated and passes from the electric heater 5 through the outlet 24 into the tub 2 to take there moisture in a drying process from pickled laundry. Thereafter, the moisture-laden process air passes through the inlet 14 to the air-to-air heat exchanger 25, where it is cooled to condense the moisture. 26 means a cooling air inlet and 27 a cooling air outlet.
