Patent ID: 7383593

Claim:
A toilet assembly comprising: a bowl assembly having a wastewater inlet and a wastewater outlet; a fragmentation passage having a passage, an inlet, and an outlet, said inlet and said outlet each in fluid communication with said passage; said passage having an upper portion, that is above a water line, and a lower portion, that is below a water line; said fragmentation inlet coupled to, and in fluid communication with, said bowl assembly waste outlet; a jet assembly having a passage with an upstream end and a downstream end; said jet assembly coupled to, and in fluid communication with, said passage lower portion; and a water system coupled to and in fluid communication with said bowl assembly and said jet assembly, said water system structured to deliver a quantity of water to said bowl assembly and said jet assembly and to remove wastewater from the fragmentation passage, wherein said fragmentation passage includes an anti-backup valve biased to the first position and disposed between said fragmentation inlet and said outlet; wherein said anti-backup valve is structured to move between a first, closed position, wherein said anti-backup valve blocks the passage of fluid between said fragmentation inlet and said outlet, and a second, open position, wherein said anti-backup valve allows fluid to pass between said fragmentation inlet and said outlet; wherein said jet assembly is structured to introduce a water stream into said passage at a high velocity and at a location adjacent to, and downstream of, said anti-backup valve; and wherein said jet assembly water stream creates a low-pressure zone behind said anti-backup valve, said low pressure being sufficiently strong to overcome the bias of said anti-backup valve so that said anti-backup valve moves to said second, open position.
