Patent number: 7340848Abstract: The ambient air clothes dryer is an automated device providing axial flow of unheated ambient air through the dryer drum. The dryer may include different drum drive systems, timer and/or humidity detector controls, and a configuration utilizing a separate, portable fan for temporary, removable installation with the dryer housing to provide airflow through the drum. The ambient air dryer greatly reduces energy requirements for drying laundry when compared to conventional heated air dryers, and is quite effective in warm and/or dry climates. The ambient air dryer is portable and may be used indoors or outdoors. The device may be configured to use twelve-volt power from a motor vehicle for use in camping. When used indoors, the device may be placed with a heat source (heat register, etc.) to draw warm air through the drum while humidifying the air as it passes through damp laundry in the drum.Type: GrantFiled: July 17, 2006Date of Patent: March 11, 2008Inventor: Larry W. Ford
