Exhaust vent

摘要

An exhaust which comprises a mounting plate mountable onto the external wall of the building and having an opening therein. The exhaust vent also comprises a main body attachable to the mounting plate and having a rear face, a front face, and an aperture extending from the rear face to the front face in fluid communication with the opening of the mounting plate and the conduit. The exhaust vent also comprises a flap pivotally attached to the main body and movable between a closed position, where the aperture is blocked by the flap, and an opened position where the flap extends away from the aperture. Finally the exhaust vent comprises a first seal which surrounds the aperture when the flap is in the closed position, the seal being located on either one of the flap or the main body. This invention aims at improving air-tightness of the exhaust vent when in the flap is in the closed position.

1. An exhaust vent for allowing fluid to exit a building through a conduit opening on an external wall of the building, the exhaust vent comprising:
a mounting plate mountable on the external wall of the building, the mounting plate having an opening therein; a main body attachable to the mounting plate, the main body having a rear face facing the building, a front face facing away from the building, an aperture extending from the rear face to the front face, a top portion, and a bottom portion, the opening of the mounting plate and the aperture of the main body being in fluid communication with the conduit, the bottom portion of the main body being thicker than the top portion, providing the main body with a flared shape when viewed from the side, the front face being thus angled relative to the external wall of the building; a flap pivotally attached to the main body, the flap being movable between a closed position wherein the aperture is blocked by the flap and an opened position wherein the flap extends away from the aperture in response to a pressure of the fluid being expelled from the conduit; and a seal located on either one of the flap or the main body for sealingly closing the aperture, the seal surrounding the aperture when the flap is in the closed position.
