A method of controlling a rotatable-drum laundry drier and a rotatable-drum laundry drier implementing the method

摘要

A method of controlling a rotatable-drum laundry drier (1) for drying laundry; the rotatable-drum laundry drier (1) comprises a rotatable drum (3) for laundry (5) and moisture sensors (22) generating an electrical signal (SM) indicatives of the loaded laundry moisture/quantity. The method comprises the steps of: feeding a flow of air into the drum (3) so that it blows on the laundry (3), rotating the drum (3) about an axis of rotation (6), calculating the quantity/weight of the laundry on the basis of a first quantity (OFFSET) indicative of the behaviour of the electrical signal (SM) in an predetermined initial measuring interval (TTM) of the drying cycle, determining a main cycle interval (TTC) indicative of the time that the electrical signal (SM) takes from the beginning of the drying cycle to meet a relation with a predetermined threshold (TSH), extending the main cycle interval (TTC) on the basis of the calculated quantity/weight of the laundry and the determined main cycle interval (TTC), and interrupting the drying cycle at the end of the extended main cycle interval (TEND).
