Self-cleaning toilet

Claim 1

A self-cleaning toilet embodying the combination of an open top toilet bowl and elevated reservoir tank mounted above said bowl, the reservoir tank including a water supply inlet for supplying water to said reservoir tank for discharge to said toilet bowl, and a separate compartment within which a biodegradable chemical or biological substance can be stored, removed therefrom and admixed with water, and the liquid formed thereby supplied to the toilet bowl to clean, disinfect and deodorize said toilet bowl, which comprises: a seat and lid pivotally attached to said open top toilet bowl, the seat being pivotally attached to a side of said bowl from a juncture of attachment disposed at substantially right angles to the juncture of attachment of said lid so that the seat can be lowered atop the bowl, or raised while the lid is lowered, a circumferential seal on said bowl which seals the lid upon the bowl on closure, internal conduits and nozzle outlets, the nozzle outlets being located on the underside of said lid and communicated via said internal conduits with said water supply inlet, an outlet from the compartment within the reservoir tank through which said biodegradable chemical or biological substances can be passed, a float actuated valve located within the reservoir tank which is connected to said water supply inlet for introducing and regulating the flow of water from said water supply inlet to said tank, the flow of water being shut off when the float which actuates said float actuated valve is high due to a high water level, the flow of water to the bowl, being initiated when the float is low due to a low water level in the reservoir tank, a discharge conduit located in the bottom of said reservoir tank through which water can be discharged from said tank to the toilet bowl, a float seated within the discharge conduit of said reservoir tank through which water can be discharged from the reservoir tank for flushing the toilet, and the water level in the tank restored by the reseating of said float which permits the bowl to refill by the introduction of water through said water supply inlet to the reservoir tank which begins with the opening of said float actuated valve as the float operatively associated therewith falls with the water level, and ends with the closing of said float actuated valve as the float operatively associated therewith rises with the water level to cut off the flow of water to the tank, an eductor communicated via a first conduit with the outlet of the compartment within said reservoir tank through which said stored biodegradable chemical or biological substances can be passed, a second conduit communicating said water supply inlet with said eductor, and a third conduit extending from said eductor through said internal conduits of the lid to the nozzle outlets located within the lid of said toilet bowl, whereby water from said water supply inlet can be delivered through said eductor, and admixed with biodegradable chemicals or biological substances due to the action of the eductor, and the liquid then discharged via the nozzles of the lid, when the lid is closed, as a spray into the toilet bowl to clean, disinfect, and deodorize said bowl.
