Abstract (en)
Laundry drying machine (1) comprising a rotatable laundry drum (3), an electric motor (9) for rotating said rotatable laundry drum (3) about its axis of rotation (6), hot air generator means (11) configured to supply a drying airflow to the drum (3) during a drying cycle, an electronic control system (16) configured to: provide a signal (S) indicative of torque (TE) that said electric motor (9) provides to the rotatable laundry drum (3), sense the inside-temperature (T W ) of the drying airflow inside the drum (3), sense the output-temperature (T OUT ) of the airflow which flows out from the rotatable drum 3, determine a comparison threshold (THC) based on the sensed signal (S), determine a temperature-difference (T) between the sensed output-temperature (T OUT ) and the sensed inside-temperature (T W ), compare the determined temperature-difference (T) with the determined comparison threshold (THC) and stop the drying cycle according to the result of the comparison.
