To detect a reduction in the air volume when a heat pump device including a compressor is adopted as the heat source.
This clothes dryer is equipped with a heat pump device 25 including the compressor 22, a radiator 21, an endothermic apparatus 20 and a throttling means 23, an air passage 13 which leads air for drying from the radiator 21 to the endothermic apparatus 20 through a rotating drum 11, a hot air temperature detecting means 17 for the air for drying before feeding calories to clothes, for which a blower 15 for feeding the air for drying to the air passage 13 is provided, and an ambient temperature detecting means 18. The clothes dryer is also equipped with a controlling means 19 which controls the hot air temperature of the air for drying by controlling the revolution number of the compressor 22, a storing means 28 which stores the revolution number of the compressor for maintaining the hot air temperature to the ambient temperature at a specified value in a specified air volume, and an air volume reduction detecting means 29 which judges the reduction in the air volume by comparing the revolution number of the controlling means 19 and the revolution number of the storing means 28. Thus, the reduction of the air volume can be detected.
