ABSTRACT:
A method for simultaneously mechanically bonding an air duct to a clothes dryer cabinet and sealing the spaces between the duct and cabinet to prevent the escape of air therefrom, and for a clothes dryer incorporating the bonded and sealed air duct and cabinet. The clothes dryer cabinet includes a series of vertical side panels and a front panel, the front panel defining an access opening through which access to an interior of a rotatable drum can be gained. An inner surface of the front panel includes an annular flange which generally surrounds the access opening and coaxially nests with and supports the rotatable drum. The annular flange defines an air-communication opening through which, in cooperation with the air duct, air flows from the interior of the drum to a blower unit. During assembly the air duct is located by means of engagement of a locating flange provided by the front panel with a series of positioning tabs on the air duct. The engagement of the tabs with the flange position the air duct adjacent the annular flange such that the air-communication opening is generally surrounded by the air duct. The air duct is thereafter permanently mechanically bonded and sealingly attached to the front panel by a foamed-in-place gasket.
