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

摘要

A method of controlling a rotatable-drum laundry drier (1) to dry delicate laundry in a drum (3) of the rotatable-drum laundry drier (1). The method includes the steps of feeding drying air into the drum (3); rotating the drum (3) at a variable rotation speed about an axis of rotation (6); rotating the drum (3) at a first rotation speed (V1) higher than, or equal to a rotation speed, at which centrifugal acceleration of the inner surface of the drum (3) equals gravitational acceleration; making interruptions in rotation of the drum at the first rotation speed (V1); and performing, at each interruption, one or more rotation cycles (21) at a second rotation speed (V2), so that, at each cycle (21), at least part of the laundry (5) slides/tumbles slowly inside the drum (3) while remaining in contact with the inner surface of the drum (3) and/or another part of the laundry (5) contacting the drum (3).
