Abstract

A rotating drum clothes drier has an annular lint filter which rotates with the drier drum and which encircles the drier door. Heated air enters an inlet at one end of the drum, passes through the clothes in the drum (picking up lint from the clothes), through the annular lint filter and out of the drier. During operation, lint collects on the inner surface of the rotating filter, eventually building up to form a felted layer. A scraper blade fixed to the drier cabinet and aligned with (but displaced a fixed distance from) the surface of the filter peels the felted layer of lint from the filter once the thickness of the felt is such that the scraper blade contacts the lint felt. The layer of lint felt thus removed from the filter surface is then collected in a cavity within the drier door for storage and later disposal.
