Abstract

In a gravity-flush toilet the pipe connecting the rim of the bowl to the tank is extended over the level of the water in the tank until it is connected to the drainage system, to drain away odours from the bowl to the drainage system, through an exhaust fan mounted at the upper end of the extended pipe. A stop valve prevents the back of odours from the drainage system. Two sliding sealing rings are run by a pneumatic system connected to the flush switch which is able to move upwards just one or both the rings to partialize the flush. A sensor placed on the seat of the bowl automatically operates the exhaust fan and the stop valve positioned between the exhaust fan and the drainage system.
