Patent ID: 7353624

Claim:
A clothing drying machine comprising: an electrode sensor that senses a voltage, wherein said voltage varies according to a moisture content of laundry; a counting unit that counts a number of times that the voltage sensed by the electrode sensor is more than a predetermined reference voltage; and a control unit that terminates a drying operation when the number of times counted by the counting unit for a predetermined reference time is within a range of one of predetermined dryness levels; wherein the control unit, when a dryness level set when the drying operation is started is more than a predetermined reference dryness level of the predetermined dryness levels: performs the drying operation for a drying time until the number of times counted by the counting unit is in the range of the predetermined reference dryness level, additionally performs the drying operation for a time obtained by multiplying the drying time by a predetermined coefficient, and terminates the drying operation.
