US Patent 8683713 Dryer and method of detecting value of dryness

Disclosed herein are a dryer and a drying method of the same. The dryer includes a condensing unit to change water vapor evaporated from a drying object into condensate water by cooling, a condensate water storage container in which the condensate water is stored, a water level sensing device to detect a level of the stored condensate water, and a microcomputer to calculate a change rate of condensation or of the condensate water level based on the detected water level and to determine a value of dryness of the drying object. The dryer effectively performs a drying operation based on the accurately detected value of dryness of the drying object.
