ABSTRACT:
A ventilation system is provided including a blower assembly mounted within the air space in the upper portion of a toilet flush tank, which air space is communicated with the upper and interior portion of the associated toilet bowl through an overflow pipe disposed in the water tank, and the blower assembly includes an inlet opening into the air space and a air outlet with which the inlet end of conduit structure is sealingly communicated. The conduit structure extends downwardly through the interior of the flush tank, out through the bottom of the flush tank and then downwardly into the base of the toilet bowl through an individual passage formed therein with the outlet end of the passage opening lengthwise outwardly through one peripheral wall portion of a thick-walled outlet nipple for the discharge outlet from the toilet bowl, the bottom wall of the toilet flush tank being spaced above and underlying top wall portion of the toilet base and the spacing between the flush tank bottom wall and toilet base being bridged by a sleeve telescoped into diametrically enlarged adjacent ends of the corresponding passage sections. The intermediate length portion of the sleeve includes a resilient seal ring disposed thereabout and compressed between the bottom of the tank and the upper surface of the toilet base.
