Abstract
A self-cleaning lint trap includes an enclosed housing having an inlet port, an exhaust port, and a spiral chamber between the ports for imparting a circular air flow to air moving through the spiral chamber. A fine mesh screen extends across the exhaust port, and along the cylindrical side wall of the spiral chamber, for collecting lint from air passing through the chamber. A freely movable lightweight object is enclosed within the spiral chamber, and is moved about the chamber by the circular air flow to break off lint from the screens. A slot in the side wall of the chamber is fluidly connected to a lint collector, such that the compacted lint ball will be carried from the chamber through the slot and to the lint collector for later disposal.
