ABSTRACT:
A dryer control method provides for selection among a plurality of dryness levels so that the user may select a desired degree of dryness for any given type of laundry. The method includes steps of selecting one among a plurality of dryness levels; driving a drying unit holding laundry; sensing a value indicative of a water content of the laundry; comparing the sensed value with first and second predetermined values; measuring a time required for the sensed value to reach the second predetermined value from the first predetermined value; computing a drying time based on the measured time; and stopping the driving step upon expiration of the computed drying time, wherein the first and second predetermined values determine a reference value corresponding to the selected dryness level.
