PROBLEM TO BE SOLVED: To effectively apply dehumidification drying process and exhaust drying process by opening/closing a cover facing a circulating air path with a value calculated on the basis of the temperature difference between a first exhaust temperature detected after a predetermined time from the start of the operation and a second exhaust temperature detected after a predetermined time from the detection of the temperature. SOLUTION: During a preheating drying zone in the drying of clothing, the exhaust temperature of a drum outlet after lowing operation for a constant time from the start of the operation, is detected by a temperature sensor 23. The temperature difference, delta TH, between a temperature after 1.5 minutes and a temperature after 4.5 minutes, for example, is detected after the start of the operation of the temperature sensor 23 to estimate the drying capacity Y in a drum 8. Then, a time Z to the time when a cover 20 is opened (90% drying degree in constant-rate of drying zone) is estimated on the basis of the outputs of a heater 7-1 and a heater 7-2 on the basis of the result of the estimation of the drying capacity Y, the cover 20 is opened by a motor 20-1 after a lapse of the time Z, the current carrying to the heater is stopped in accordance with the output of a humidity detecting sensor 22, and the cover 20 is closed after the temperature is lowered to complete the drying.
