ABSTRACT:
A portable and removable window exhaust system for home appliances requiring outdoor venting (such as portable laundry dryer) which obviates the necessity of permanent installation and piercing an exterior wall of a building to vent the appliance to the outdoors. The main part of the system, the exhauster, is incorporated in a replacement window panel consisting of two transparent perimetrally reinforced sheets of clear transparent plastic, and forms an integral part of one of said window panels. The said exhauster is movable within the window replacement panel and, when in closed position, will not protrude from the outside of the window replacement part, giving appearance of regular closed window. Moreover, in the open position, the exhauster resembles a protective hood equipped with inter-connected spaced ribs forming a grill at the bottom edges of said exhauster, which perform as an exhaust outlet. Nevertheless, even when the exhauster is manually pushed into an open position, the replacement window insert remains tightly closed and the only functional opening at the rear of the exhauster is the one in a neck-like shape to which the flexible hose is connected. In consequence, the conventional flapper, of shutter, is eliminated and, since the said grill offers only a negligible resistance to the passage of the exhausted air, the load on the dryer electric motor is smaller, resulting in saving of electrical energy while in use.
