Abstract:
A toilet seat ventilation assembly for mounting on a toilet bowl, said toilet seat ventilation assembly secured to the toilet bowl at the two mounting holes at the back upper surface of the toilet bowl, and connected to an exhaust system for removing odors from around the toilet bowl, said toilet bowl ventilation assembly comprising:a toilet seat having a plurality of vent holes formed in a bottom surface of said toilet seat and an internal passageway connecting said vent holes to a discharge aperture at a back edge of said toilet seat; a tubular manifold positioned along the back edge of said toilet seat, said tubular manifold including an inlet aperture and an outlet aperture formed in a side surface of said manifold adjacent an end of the manifold; a first seat hinge and a second seat hinge rotatably mounted on opposite ends of said tubular manifold and connected to the back edge of said toilet seat to facilitate the selective movement of the toilet seat between a horizontal position engaging the toilet bowl and a vertical position, the first seat hinge being positioned adjacent the discharge aperture, and having a passageway formed in said hinge for selectively connecting the discharge aperture of said toilet seat to the inlet aperture of said manifold; a first mounting fixture and a second mounting fixture for rotatably securing the tubular manifold, said mounting fixtures positioned at opposite ends of the manifold adjacent said seat hinges, and positioned on the toilet seat at the mounting holes for securing said tubular manifold and the toilet seat to the toilet bowl, each of said mounting fixtures having an externally threaded bolt extending down from a body of the mounting fixture through the mounting holes and having a nut to secure the mounting fixtures on the toilet bowl, and the first mounting fixture being positioned about the outlet aperture of said manifold and having a passageway extending from the manifold through the body of said first mounting fixture and through the length of the externally threaded bolt; and a toilet seat cover having a pair of hinges extending from a back edge of said toilet seat cover and connected to said manifold, said toilet seat cover rotating said tubular manifold when the toilet seat cover is selectively moved between a horizontal position adjacent the toilet seat and a vertical position, whereby, when the toilet seat cover is in the vertical position and the toilet seat is in the horizontal position, the passageway in the first seat hinge is aligned with the inlet aperture and the passageway of the first mounting fixture is aligned with the outlet aperture of the tubular manifold, and an air communication passage is established from the vent holes through the internal passageway of the toilet seat through the discharge aperture through the seat hinge through the manifold through the mounting fixture and the externally threaded bolt to the exhaust system, and whereby when the toilet seat and toilet seat cover are both in the vertical position or both in the horizontal position, the passageway of the first seat hinge is not aligned with the inlet aperture of said manifold such that the air communication passage is blocked.
