DRYER

PURPOSE:To enable automatic setting of the optimal hot air ventilation time by incorporating in a control part a construction in which a combination of the detected temperature of a room temperature sensor, the detected moisture and the detected temperature of a hot air temperature sensor determines the time for which hot air is blown to an object to be dried. CONSTITUTION:A room temperature 11 and a moisture sensor 12 comprising a thermistor are arranged in the vicinity of an inlet 11. In addition, in the vicinity of an outlet 4 is provided a hot air temperature sensor. Then the room temperature sensor 11, a moisture sensor 12 and the hot air sensor 13 are connected to a control circuit of a control part 10. The control circuit determines the hot air ventilation time until the completion of the drying operation by a predetermined combination based on the room temperature detected by the room temperature 11, the moisture detected by the moisture sensor 12 and the hot air temperature detected by the hot air temperature sensor 13. For the hot air ventilation time a heater 2 and a fan mower 3 are operated.
