Abstract

A toilet. The toilet comprises a main receptacle for receiving feces and urine, a urine and a fecal receptacle at least a portion of each disposed below said main receptacle for respectively receiving and storing urine and fecal matter. Said main receptacle defining one or more urine apertures in a lower region thereof through which urine may flow out of said main receptacle downwardly into the urine receptacle, said main receptacle shaped to divert urine into the one or more urine apertures. Said main receptacle defining one or more fecal apertures in the lower region thereof through which feces and urine may leave the main receptacle and pass downwardly. Said one or more fecal apertures having a raised perimeter for preventing urine from entering said one or more fecal apertures, and said feces receptacle for receiving and storing feces that falls downward through the feces aperture.

Claims

1. A toilet, comprising:

a main receptacle for receiving feces and urine of a user;

a urine receptacle having at least a portion thereof disposed below said main receptacle;

a feces receptacle having at least a portion thereof disposed below said main receptacle;

said main receptacle defining a urine aperture in a lower region thereof through which urine flows under influence of gravity into said urine receptacle;

said main receptacle defining a fecal aperture in the lower region thereof through which feces flows under influence of gravity into said feces receptacle;

a raised barrier extending upwardly around a periphery of said fecal aperture;

a diverter panel moveable between a closed and an opened position for closing and opening said fecal aperture, the diverter panel disposed below the fecal aperture when in said closed position;

dual paths for urine to flow from said main receptacle into said urine receptacle when said diverter panel is in said closed position, a first path bounded by said raised barrier that directs urine flow around said periphery through said urine aperture into said urine receptacle, and a second path along which urine strikes an upper surface of said diverter panel then flows through an opening between said fecal aperture and said upper surface of the diverter panel into the urine receptacle without passing through the urine aperture; and

a single path for urine to flow from said main receptacle into said urine receptacle when said diverter panel is in said opened position, said single path bounded by said raised barrier that directs urine flow around said periphery through said urine aperture into said urine receptacle.

2. The toilet of claim 1 said raised barrier measuring a minimum of ¼

inch from a lowest adjacent surface of said main receptacle.

3. The toilet of claim 1 where said raised barrier varies in height above a surface of the main receptacle, the height increasing in a direction toward the urine receptacle.

4. The toilet of claim 1 said feces receptacle comprising an agitator for use in mixing the feces with a material added to said feces receptacle, the action of mixing providing increased aeration of contents of said feces receptacle to facilitate composting of said contents.

5. The toilet of claim 4 said agitator disposed in an approximately diagonal orientation, said agitator comprising a first end located anywhere above approximately an uppermost third of said main receptacle and an opposite second end located below approximately a lowermost third of said main receptacle, said feces receptacle defining an opening to secure said upper end of said agitator and through which a portion of said agitator proximate the first end passes.

6. The toilet of claim 5 said feces receptacle comprising a receiving region within an interior surface thereof to secure said second end of said agitator.

7. The toilet of claim 1 said feces receptacle comprising an outlet for use in transferring feces to a secondary feces receptacle or to a remote site.

8. The toilet of claim 1 having one or more apertures for supplying water or a diluent into the feces receptacle and for evacuating feces receptacle contents.

9. The toilet of claim 8 said one or more apertures comprising a component for providing a high-pressure spray of said water or said diluent.

10. The toilet of claim 9 said one or more apertures further comprising a rotatable component for permitting rotation of said component for providing a high-pressure spray.

11. The toilet of claim 8 said one or more apertures comprising a male barbed fitting for interfacing with a mating fitting attached to a hose.

12. The toilet of claim 8 said one or more apertures configured to receive a marine discharge hose having an inner diameter between ⅝

inch and 1.5 inches.

13. The toilet of claim 1 wherein the arrangement of said urine aperture and said fecal aperture effects separation of the urine and feces into their respective urine aperture and fecal aperture.

14. The toilet of claim 1 further comprising a fan for circulating air through said fecal receptacle to facilitate evaporation of moisture in said fecal receptacle.

15. The toilet of claim 14 defining an air flow path through which said fan circulates air, said air flow path passing through said fecal receptacle and said urine receptacle.

16. The toilet of claim 1 said fecal receptacle and said urine receptacle each independently detachable from the main receptacle.

17. The toilet of claim 1 said main receptacle comprising an upper bowl portion and a lower bowl portion.

18. The toilet of claim 17 wherein at least one of said upper bowl portion and said lower bowl portion defines urine pathways extending from said fecal aperture and oriented to direct urine away from said fecal aperture and toward the urine aperture.

19. The toilet of claim 18 wherein said urine pathways are disposed in said upper bowl portion and comprise inclined surfaces directing urine away from said fecal aperture and directing urine toward said urine aperture.

20. The toilet of claim 18 wherein said urine pathways are disposed in said lower bowl portion and comprise inclined surfaces directing urine away from said fecal aperture and directing urine toward said urine aperture.

21. A toilet, comprising:

a main receptacle for receiving feces and urine of a user;

a urine receptacle having at least a portion thereof disposed below said main receptacle, the urine receptacle for receiving and storing urine;

a feces receptacle having at least a portion thereof disposed below said main receptacle, the feces receptacle for receiving and storing feces;

said main receptacle defining a urine aperture and a feces aperture in a lower region thereof, wherein urine flows under the influence of gravity through said urine aperture into said urine receptacle, and wherein feces flows under the influence of gravity through said feces aperture into said feces receptacle;

a vertical barrier extending upwardly around a periphery of the fecal aperture, the vertical barrier for preventing urine from entering said fecal aperture;

an inclined surface disposed below the urine aperture;

a diverter panel moveable between a closed and an opened position for closing and opening said fecal aperture, the diverter panel disposed below the fecal aperture when in said closed position;

dual paths for urine to flow from said main receptacle into said urine receptacle when said diverter panel is in said closed position, a first path bounded by said raised barrier that directs urine flow around said periphery through said urine aperture into said urine receptacle, and a second path along which urine strikes an upper surface of said diverter panel then flows through an opening between said fecal aperture and said upper surface of the diverter panel into the urine receptacle without passing through the urine aperture;

a single path for urine to flow from said main receptacle into said urine receptacle when said diverter panel is in said opened position, said single path bounded by said raised barrier that directs urine flow around said periphery through said urine aperture into said urine receptacle; and

said feces receptacle for receiving and storing feces that falls downward through the feces aperture into said feces receptacle.

22. A toilet, comprising:

a main receptacle for receiving feces and urine of a user;

a plurality of urine flow paths extending from the main receptacle to a urine receptacle;

a feces receptacle having at least a portion thereof disposed below said main receptacle;

said main receptacle defining a urine aperture in a lower region thereof through which urine may flow out of said main receptacle under the influence of gravity into the urine receptacle, said main receptacle shaped to divert urine into the one or more urine apertures;

said main receptacle defining a fecal aperture in the lower region thereof through which feces and urine may leave the main receptacle under the influence of gravity;
