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 (5); 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 (5) moisture and/or quantity, the method comprises the steps of: feeding a flow of air into the drum (3) so that it blows on the laundry (5), rotating the drum (3) about an axis of rotation (6), calculating the quantity and/or weight of the laundry (5) 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 and/or weight of the laundry (5) and the determined main cycle interval (TTC), and interrupting the drying cycle at the end of the extended main cycle interval (TEND).
