ABSTRACT:
An exhaust vent cover for closing the exhaust vent when the exhaust vent is not in use is shown. The exhaust vent cover includes a peripheral flange for attaching the cover to a surface and a continuous hollow body extending upwardly from the flange and having an open front as well as an air passageway communicating with this open front. The continuous hollow body further includes an overhang extending beyond the open front, a grill covering the open front to prevent access to the inside of the continuous hollow body, and a valve located inside the hollow body across the air passageway. The exhaust vent cover also includes a sloped upper surface to prevent the valve from being blown open.
