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.

Abstract: An exhaust system for home appliances requiring outside venting, such as a portable laundry dryer, which obviates the necessity of piercing an exterior wall to vent the appliance to the outside. The system includes a transparent window insert plate assembly, removably insertable within a window opening and having an exhaust outlet and a flexible air hose having means at both ends to removably connect the same with the air outlet of a laundry dryer and with the exhaust outlet of the window insert plate assembly. The latter outlet has closure means to seal the window opening when the dryer is not in use. This closure means can be automatically closable, or manually closable. In the latter case, it can be arranged so that no part will protrude from the outside of the window in the closed position.
