Abstract: The present invention provides a garment dryer including a heat pump device. The inventive garment dryer has an improved heat exchange efficiency without uneven airflow around a heat exchanger (a heat absorber and a radiator) of the heat pump device. A heat exchange air duct portion (22) is defined in a heat pump unit (14). A heat absorber (23) and a radiator (24) are provided as a heat exchanger in the heat exchange air duct portion (22). An upstream buffer space (33) for changing the flow direction of air to regulate the flow rate of the air is provided upstream of the heat absorber (23). A downstream buffer space (34) for regulating the flow rate of the air is provided downstream of the radiator (24). As a result, the airflow around the heat exchanger is uniformly regulated, thereby improving the heat exchange efficiency of the heat exchanger.
