Claim:
A steam dryer control method comprising: turning on a steam heater; turning on a water supply valve and counting the number of lapses of unit water supply period at any time when the unit water supply period elapses; and rotating a drum when the number of lapses of the unit water supply period reaches a preset number, wherein rotating the drum includes the steps of: determining whether a steam drying cycle is completed, after rotating the drum; if the steam drying cycle is completed, determining whether an actual humidity inside the drum is less than or equal to a preset humidity; if the steam drying cycle is not completed, returning to the step of turning on the water supply valve; and if the actual humidity is greater than the preset humidity, turning on a drying heater; if the actual humidity is not greater than the preset humidity, cooling an interior of the drum, and wherein determining whether the steam drying cycle is completed depends on whether the number of operations of a drum motor has reached a predetermined number of operations after the water supply valve is turned on.
