Abstract
Abstract An improved toilet stool having an annular conduit seat with intake openings in communication with the inside of the toilet bowl. The improvement being a ventilating means which comprises an adapter plate situated underneath a tank. The adapter plate has a structure defining a conduit which is in communication with the toilet bowl through the intake openings of the seat. A means is attached within the tank or underneath a compartment attached to the adapter plate and removes normally contaminated air from the inside of the toilet bowl through the intake openings and the conduit of the adapter plate for passing it either into the outside atmosphere through a means for conducting in communication therewith, or into the surrounding atmosphere after passage through a means for filtering. A switch means is connected within the adapter plate and is electrically operably connected to the means for removing. The toilet seat includes a rear protrusion member extending into the adapter plate, and a linkage member is provided connecting between the switch means and the protrusion member such that pressure exerted on the top of the seat causes the linkage member to operate the switch means to activate the means for removing.
