Washer dryer and method of operating a washing and drying

Laundry dryer having a washing liquid container (1) is rotatably mounted in which a laundry drum (11) for accommodating laundry, an adsorption module (2) containing an adsorbent for receiving humidity, a blower (6), which for the exchange of process air between is formed the solution container (1) and the adsorption module (2), a condenser (3), a tub inlet heating element (51) which is arranged in a liquor tank inlet line (41), and a control device, which is formed during a drying phase by means of of the fan (6) dry process air from the adsorption module (2) in such a way into the tub (1) to direct that moisture is discharged from the laundry to the process air, and during a washing phase by means of the fan (6) moist process air from the adsorption module ( directing 2) in such a way into the tub (1) so that moisture is condensed from the process air to the laundry and the laundry is heated by this condensation process liberated heat of condensation, characterized in that the control device is formed, the drying phase to operate while the adsorption module (2), the condenser (3), which liquor tank inlet heating element (51) and the fan (6) in such a way that - for a first sub-phase laden with moisture from the laundry process air is passed through the condenser (3) where moisture is condensed from the process air and the process air is cooled, and then the cooled process air from the condenser (3) by means of the lye tank inlet heating element (51) is heated and returned to the washing liquid container (2) is passed, and - during the first sub-phase following the second sub-phase where moisture is adsorbed from the process air on the adsorbent laden with moisture from the laundry process air is passed through the adsorption module (2), and then exiting from adsorption module (2) process air by means of the Laugenbehalterzulauf- the heating element (51) is heated and then into the tub (1) is passed.
