Abstract
Abstract A tumble dryer for small articles of clothing having no motor or heater utilizes the output of a hair dryer to both rotate a drum containing the articles of clothing and to dry the articles. Turbine blades mounted on the periphery of the drum slowly rotate the drum to prevent uneven drying of the clothing in the warm air output from the dryer. A tray mounted beneath the drum can be used to catch water dripping from the clothing. Removing the tray allows the hot air to escape from the bottom of the unit for warming the room or drying hands. The tumble dryer and its associated hair dryer are preferably wall-mounted.
