ABSTRACT:
The invention consists of a ventilating system and particularly a ventilating kit to be installed on a conventional toilet bowl at the rear of the toilet seat above the apertures used to anchor the toilet seat to the toilet bowl. The kit includes a parapet-like housing having a peripheral wall member adapted to be mounted over and in contact with the back apron of the toilet bowl and disposed to encircle both apertures vertically extending therethrough. A pair of hollow T-shaped couplings are adapted to be mounted below each of the apertures for providing an air passageway from the housing through the apertures and into a piping arrangement which projects into an adjacent wall of the toilet room wherein a suction device is located. A cover is fittingly mounted over the parapet-like housing and has a pending lip facing the seat cover and adjacent thereto for defining an air passageway extending between the rear of the bowl and inside the housing. Upon actuation of the suction device, air is withdrawn from the bowl adjacent the seat cover, through the housing and the apertures located through the apron. The air pathway extends through the couplings and through the piping arrangement for projecting the air through the walls of the toilet room. One of the essential features of the present invention consists of using the apertures conventionally provided through the apron at the rear of the toilet bowl.
