Rotatable-drum laundry drier and method of controlling a rotatable-drum laundry drier to dry delicate laundry

摘要

Laundry dryer (1) comprising: a laundry drum (3) which is designed to rotate about an longitudinal axis (6); an air recirculating conduit (10) connected to said laundry drum (3) ; heater device (10) located along air recirculating conduit (10) to heat the airflow; a rotatable fan (11) located along air recirculating conduit (10) to produce an airflow flowing through drum (3); the fan (11) being designed to be rotated in a main and secondary direction of rotation for providing different air flow rates; an electric motor (14) which is mechanically connected with the fan (11) and the drum (3) for rotating the fan (11) and drum (3), simultaneously. The home laundry dryer (1) comprising electric control means (18) configured to control said electric motor (14) so as to cause: the drum (3) to rotate at a first rotational speed (v1) in a forward direction of rotation, thereby resulting in the fan (11) being rotated in the main direction of rotation for providing a first air flow rate; or the drum (3) to rotate at a second rotational speed (v2) greater than said first rotational speed (v1) in a reverse direction of rotation, thereby resulting in the fan (11) being rotated in the secondary direction of rotation for providing a second air flow rate lower than the first air flow rate.
