ABSTRACT:
An air venting apparatus to be mounted into the water tank of a water closet for evacuating to the outside of the room where the water closet is located the stale air escaping from the toilet bowl. The apparatus comprises a main, generally closed air chamber; a powered fan member, anchored into the air chamber for developing negative pressure therein; a support for supporting the air chamber at the top portion of the water tank whereby the fan remains constantly above water level. A siphon assembly is provided for fluidingly interconnecting in substantially air tight fashion the discharge pipe to an upstream section of the air chamber, whereby the siphon assembly is adaptable to fit discharge pipes of variable locations within the water tank; and a nozzle assembly is provided for fluidingly interconnecting a downstream end of the air chamber to the outside of the room. No modification of the water tank nor the water tank lid is required for the installation of this apparatus.
