Abstract
Abstract A toilet facility for use in boats, campers, mobile homes, recreational vehicles, land and water cruisers, residences, basement flush up, and the like, is disclosed. The toilet facility utilizes a minimum amount of flush water and includes a modified water closet bowl of the siphon type, a sump tank, a macerator pump means, and a water closet tank. A macerator pump means is coupled in fluid communication between a holding tank or other disposal means and the sump tank. The macerator pump is electrically energized through a control circuit when the flush handle is tripped. The duration of the flush cycle may be controlled by a timing circuit which will automatically shut off the macerator pump. Also, the macerator pump may be shut off by the control circuit sensing that the flush cycle is complete, that is, when the macerator pump is pulling only air therethrough or when the control circuit senses the absence of water at the macerator pump inlet. All of the waste and contaminated water is evacuated from the bowl leaving clean, uncontaminated water in the bowl to provide a water seal after the flush cycle is completed and when the toilet facility is not in use. When the macerator pump is in operation, the water is drawn from the bowl through the pump and either into a holding tank or other waste disposal or treatment means.

Claim 1
Independent Claim
430 words
In a toilet facility of the type having a modified water closet bowl of the siphon type and which utilizes a minimum amount of flush water sufficient to wash the water closet bowl after each flush cycle so that only clean, uncontaminated water remains in the bowl after all waste is evacuated therefrom, said toilet facility comprising: a hollow rim formed around the upper edge of said bowl, said hollow rim having a water inlet opening and a plurality of spaced outlet openings formed therein and disposed adjacent said bowl surfaces so that all water entering said hollow rim will pass through said outlet openings to wash said bowl surfaces; flush valve means mounted in fluid tight connection with said water inlet opening of said hollow rim; said bowl including an integrally formed up-leg having a bowl waste inlet opening and a down-leg having a bowl waste outlet opening so as to define a bowl waste passageway of the siphon type; a sump tank having a waste passageway therein and waste inlet and waste outlet openings formed at each end respectively of said passageway; said bowl mounted on said sump tank in fluid tight connection with said sump waste inlet opening and said bowl waste outlet opening so that said bowl waste passageway and said sump waste passageway are in fluid communication to provide a continuous waste passageway; a macerator pump mounted on said sump tank in fluid tight connection with said sump waste outlet opening, said macerator pump having waste inlet and outlet openings; actuating means operatively connected to said flush valve means for opening said flush valve to permit water to enter said hollow rim through said water inlet opening; a control circuit including flush cycle control means electrically connected to said valve actuator means and said macerator pump so that when said flush valve is opened by said actuator means to permit water to enter said hollow rim through said water inlet opening, said flush cycle control means is electrically energized and simultaneously electrically energizes said macerator pump to pump waste rapidly from said bowl without siphonic action and is electrically deenergized when waste is removed from said bowl whereby a minimum of flush water of less than one gallon is utilized and is sufficient to wash the water closet bowl of waste so that only clean uncontaminated water remains in said bowl and provides a water seal when the flush cycle is completed, said control circuit including sensing means operably associated with said pump for shutting off said pump when only air is being pumped therethrough.
Claim 2
Dependent Claim
430 words
In a toilet facility of the type having a modified water closet bowl of the siphon type and which utilizes a minimum amount of flush water sufficient to wash the water closet bowl after each flush cycle so that only clean, uncontaminated water remains in the bowl after all waste is evacuated therefrom, said toilet facility comprising: a hollow rim formed around the upper edge of said bowl, said hollow rim having a water inlet opening and a plurality of spaced outlet openings formed therein and disposed adjacent said bowl surfaces so that all water entering said hollow rim will pass through said outlet openings to wash said bowl surfaces; flush valve means mounted in fluid tight connection with said water inlet opening of said hollow rim; said bowl including an integrally formed up-leg having a bowl waste inlet opening and a down-leg having a bowl waste outlet opening so as to define a bowl waste passageway of the siphon type; a sump tank having a waste passageway therein and waste inlet and waste outlet openings formed at each end respectively of said passageway; said bowl mounted on said sump tank in fluid tight connection with said sump waste inlet opening and said bowl waste outlet opening so that said bowl waste passageway and said sump waste passageway are in fluid communication to provide a continuous waste passageway; a macerator pump mounted on said sump tank in fluid tight connection with said sump waste outlet opening, said macerator pump having waste inlet and outlet openings; actuating means operatively connected to said flush valve means for opening said flush valve to permit water to enter said hollow rim through said water inlet opening; a control circuit including flush cycle control means electrically connected to said valve actuator means and said macerator pump so that when said flush valve is opened by said actuator means to permit water to enter said hollow rim through said water inlet opening, said flush cycle control means is electrically energized and simultaneously electrically energizes said macerator pump to pump waste rapidly from said bowl without siphonic action and is electrically deenergized when waste is removed from said bowl whereby a minimum of flush water of less than one gallon is utilized and is sufficient to wash the water closet bowl of waste so that only clean uncontaminated water remains in said bowl and provides a water seal when the flush cycle is completed, said control circuit including sensing means operably associated with said pump for shutting off said pump when only air is being pumped therethrough.
