Abstract
Method for controlling a drying course of a laundry dryer including the steps of (a) starting a drying course by using high temperature drying air, and sensing dryness of a drying object periodically, (b) determining a dryness saturation time point at which the dryness sensed thus exceeds a preset reference value Q, (c) determining a load of the drying object according to the drying saturation time point T_sat, and (d) varying a drying algorithm depending on the load of the drying object determined thus, whereby preventing a small amount of laundry from sticking to a drum in a drying course by varying a control algorithm of the drying motor in a case an amount of the drying object is determined to be small accurately with reference to a saturation time point of an electrode sensor.
