Abstract:
A toilet venting apparatus for a toilet, wherein said toilet includes a tank and a bowl, said apparatus comprising:an upper insert mountable between said tank and said bowl,a lower insert mountable between said bowl and a floor sewer pipe,said upper insert having a first aperture therethrough for cooperating between a flush valve aperture in a lower wall of said tank and a water-entry aperture in an upper surface of said bowl, said water-entry aperture cooperating, via a manifold in said bowl, in fluid communication with water dispensing apertures around an upper rim of said bowl,a flush valve adapted for placement in said tank and actuable so as to release flush water held in said tank through said flush valve aperture, said first aperture, said water-entry aperture, said manifold and said water dispensing apertures to thereby flush said toilet,said upper insert having a first conduit in fluid communication with said first aperture, said first conduit extending from said first aperture to a first outlet said first outlet opening externally from said upper insert,said lower insert having a second aperture therethrough for cooperating between a down-leg discharge aperture of said bowl and an inlet aperture of said floor sewer pipe,said lower insert having a second conduit in fluid communication with said second aperture, said second conduit extending from said second aperture to a second outlet, said second outlet opening externally from said lower insert,a third conduit mountable in fluid communication between said first and second outlets,a water driven turbine mounted to said third conduit, a water supply mounted to an impeller side of said turbine,an actuator for biasing to an open position a water supply valve mounted on said water supply so as to supply water under pressure to said impeller side of said turbine to thereby turn an impeller of said turbine, said impeller co-axially mounted to a fan of said turbine, said fan in fluid communication with said third conduit,wherein said actuator is a manual water supply valve actuator manually, translationally movable between first and second water supply valve biasing positions, wherein in said first water supply valve biasing position said water supply valve is biased into said open position, said apparatus further including a flush valve linkage for actuating said flush valve and a return actuator cooperating with said flush valve linkage, said manual water supply valve actuator being biased from said first water supply valve biasing position to said second water supply valve biasing position by movement of said flush valve linkage, which moves said return actuator into biasing contact with said manual water supply valve actuator, wherein in said second water supply valve biasing position said water supply valve is biased into a closed position,wherein, when said first insert is mounted between said tank and said bowl, and said second insert is mounted between said bowl and said floor sewer pipe, and said third conduit is mounted to said first and second outlets, turning of said impeller turns said fan so as to draw air into said third conduit from said bowl via said water dispensing apertures, said manifold and said first conduit, said fan urging said air down said third conduit, so as to pass through said second conduit and into said floor sewer pipe.
