  • Vapor saving ambient air intake system for a dry cleaner
    Patent number: 3978694
    Abstract: An ambient air intake system for a dry cleaner is disclosed which draws room air through the access opening when the door to the machine is open and vents this air to an outlet without passing it through the interior tubs which contain residual solvent vapor laden air. To accomplish this an air duct is interposed between the access opening of the cabinet housing the dry cleaner and the open end of the interior tubs, with the duct effectively sealed about the periphery of the cabinet opening and the open end of the outer tub and having aligned openings therethrough to define a passageway through which the clothes are inserted and removed. The duct is connected to an electrically actuated normally closed valve which in turn is connected to the inlet of a motor driven fan, the outlet side of which leads to an exhaust pipe.
