Abstract (en)
[origin: WO2013167489A2] The invention relates to a method for operating a dryer (1) comprising a drum (2) for pieces of laundry (5) to be dried, a moisture sensor (7), an electric, variable-speed drive motor (12) for the drum (2), a control unit (11) and a process air duct (3) in which a heating unit (4) and a process air blower (6) are located, said method comprising the steps: (a) determining a load Linit of the drum (2) at the start of loading; (b) operating the drive motor (12) at a speed v in a range v1 <= v <= v2; (c) producing hot process air by operating the heating unit (4) and the process air blower (6) and rotating the drum (2) at a speed ù, wherein ù1 < ù < ù2, and passing said air through the drum (2); (d) measuring a moisture W of the pieces of laundry (5) by means of the moisture sensor (7); (e) determining a load LWu of the drum (2) when a moisture W smaller or equal a predetermined threshold value Wu is reached; (f) determining the dry weight Wdry of the pieces of laundry (5) once it is established that the load L is within a range defined by a minimum load Lmin and a maximum load Lmax , such that Lmin <= L <= Lmax; and (g) increasing the speed v of the drive motor (12) and the speed ù of the drum (2) depending on the determined dry weight Wdry and the moisture W. The invention further relates to a dryer suitable for performing said method.
