Abstract: PURPOSE:To eliminate the set of a drying course to be selected in correspondence to the type of cloth by counting a time from the start of drying operation to the arrival of a drying rate to a first reference value, comparing the time with a drying operation forecasting time and deciding the type of an object to be dried. CONSTITUTION:A count time T2 is calculated from the start of the drying operation, which is counted by a microcomputer 12, to the achievement of a drying rate detecting signal Vt2 to a first reference value (a) and the time is set to the microcomputer 12. Continuously, the count time T2 is compared with a drying operation forecasting time T1 by the deciding means function of the microcomputer 12. For example, in the case of T1-T2<30 minutes, the object to be dried is decided as the standard cloth such as cotton, etc., (excepting for chemical fiber) and in the case of T1-T2>=30 minutes, the object to be dried is decided as the chemical fiber. It is judged whether the drying rate detecting signal Vt2 at a sampling time t1 reaches a second reference value (b) or not. The time, when the drying rate detecting signal Vt2 reaches the second reference value (b), is so-called 'drying detection' and after that, drying operation is executed for a fixed time. Then, a motor 7 and a heater 8 are interrupted and the drying operation is finished.
