TOILET SEAT WITH PASSAGE SYSTEM FOR REMOVAL OF FOUL AIR

摘要

A ventilating apparatus for a toilet comprises a toilet seat having a rear end and an interior surface extending around a central opening. A primary venting passageway is formed in the seat and extends from the rear end and along opposite side sections and has at least one vent outlet located at the rear end. Inlet apertures are distributed around the interior surface and are in fluid communication with the passageway. Two hinge mechanisms are provided to pivotally connect the rear end of the seat to the toilet bowl and at least one of these mechanisms includes a threaded connecting pin member having a further venting passageway extending therethrough. This further passageway has an upper end which can be sealingly connected to the outlet at the rear of the toilet seat. Another venting outlet located at the bottom end of the pin member can be connected to a vacuum source for withdrawing foul air by means of the venting passageways.
