ABSTRACT:
A ventilated toilet includes a flapper valve assembly having coaxial air intake and air discharge tubes, the outer air intake tube being connected at its lower end to the flush discharge outlet of the holding tank of the toilet. The inner tube protrudes downwardly through the flush discharge outlet and through the porcelain wall separating the siphon portion of the toilet waste discharge duct from the flush conduit connecting the flush discharge outlet of the holding tank to the annular water discharge channel in the rim of the toilet bowl. An electric fan withdraws contaminated air from the toilet bowl through the annular discharge channel and upwardly through the annular channel between the inner and outer flapper valve tubes and vents downwardly through the inner tube to the siphon portion of the waste duct to be discharged. A conventional flapper valve is offset from and connected to the outer one of the pair of coaxial tubes.
