To detect the lowering in an air volume when a heat pump device including a compressor is adopted as a heat source.
This clothes drying apparatus is provided with the heat pump device 14, a heat radiating state detecting means 18 detecting the heat radiating state in a radiator 10 of the heat pump device 14, a control means 19 fixedly retaining the heat radiating state based on data of the heat radiating state detecting means 18, and a heat absorbing state detecting means 20 detecting the heat absorbing state in a heat sink 12 of the heat pump device 14. This clothes drying apparatus, when the detection data of the heat absorbing state detecting means vary beyond a predetermined range from a determination reference setting value in a state of controlling the heat absorbing state to a predetermined value, determines occurrence of air volume variation.
