Abstract
A vent adaptor is disclosed which is suitable for attaching to the end of a dryer vent to connect the dryer vent to the building exterior through an existing wall opening. The vent adaptor includes a T-shaped hollow fitting which is fabricated with a vertical connector leg attachable to the end of the dryer vent and an intercommunicating hollow, horizontal conduit. The horizontal conduit includes a forward, insulating branch which forwardly terminates in a transition piece for frictional engagement within the building wall and a horizontally juxtaposed, rearwardly positioned storage branch in communication therewith. An insulating plug is reciprocal within the conduit from a storage position within the storage branch to an insulating position within the building opening whereby the building opening can be plugged when the dryer is not in use. A filter is removably secured in the storage branch interiorly of the storage plug in such a manner that warm, moist air from the dryer may be directed interiorly of the building through the filter when the insulating plug is reciprocated to its insulating position within the building wall opening.
