Abstract A ventilating device for a toilet stool having a chamber means which fits the top of the bowl of the toilet. Within the chamber are a plurality of separate flow passages through which malodorous air within the bowl is drawn by a suction means which is connected to the plurality of flow passages. In this manner, odors are removed from the toilet bowl, preferably to a filtering apparatus.

Claim 1
Independent Claim
235 words
A ventilating device for a toilet stool having a toilet bowl and a seat pivotally connected thereto, said bowl having an enlarged opening, comprising: an air chamber means adapted to fit the top of said bowl and positioned between said seat and said bowl, said chamber means having an inner wall adjacent said enlarged opening, said inner wall having a plurality of orifices spaced around the exterior thereof to receive air from said bowl, said chamber means having a plurality of conduits therein, said conduits being respectively connected to said orifices such that each conduit defines a separate flow passage from the associated orifice; discharge connector means connected to said conduits for receiving air discharged from said conduits; suction means for removing air from said bowl to remove odors therefrom; conveying means connecting said suction means and said discharge connector means for conveying air from said chamber means to said suction means; a valve moveably secured in said chamber means, said valve having an inlet to receive air from said bowl, said valve being connected to one of said conduits, said valve being positionable to register said inlet and said one of said conduits to allow flow of air from said bowl into said chamber means and to move said inlet out of registration with said one of said conduits; and switch means operably connected to said suction means to selectively actuate said suction means.
