Title:
COMPACT RECYCLING ELECTRIC DEHYDRATION TOILET
Document Type and Number:
WIPO Patent Application WO/2001/072193
Kind Code:
A1
Abstract:
A self-contained toilet (20) that has no water consumption and does not use chemicals. A toilet bowl (6) cleaned by combining compressed air and liquid through jets (5) to reduce flush volume. The flush liquid supply reclaimed through distillation. The dehydration chamber (8) cleaned by scraping and blowing of the waste. The dehydration process coming from a highly efficient heat, air and grinding chamber (8). The air compressor (43) pressurizing the tank (26) to clean the bowl (6) and/or empty and dehydrate the chamber (8) contents. The compressor (43) intake used to eliminate odors from the bowl (6) and vent the humidity from the dehydration process. The dehydration process controlled through temperature sensors (16) that detect relative humidity. A toilet (20) wherein it will operate while being used, flush within two minutes and the dehydration process able to be interrupted repeatedly with other deposits of human waste then resume operation until fully dehydrated.

Claims:
CLAIMS What Is Claimed Is:
1. An apparatus for safely disposing of human waste without water consumption or chemicals, which electrically produces a dry powdered waste product comprising: a toilet bowl; an air nozzle directing air into said bowl; a heater for heating said waste; a grinder for grinding said waste into a powder, said grinder connected to said toilet bowl; and a receptacle for recovering said powdered waste.
2. An apparatus for safely disposing of human waste without water consumption or chemicals, which electrically produces a dry powdered waste product comprising: a toilet bowl; distribution means directing air and liquid into said bowl; waste drying means connected to said bowl, said waste drying element including entrance means and exit means; waste cleaning means disposed within said bowl; and a waste receptacle for recovering dried waste produced by said waste drying element.
3. The apparatus of claim 2, wherein said waste drying means is a dehydration chamber.
4. The apparatus of claim 3, wherein said air and said liquid are combined for flushing of said toilet bowl in order to reduce consumption and increase cleaning force.
5. The apparatus of claim 4, wherein said liquid is water.
6. The apparatus of claim 5, wherein said water is reclaimed from a dehydration process occurring within said dehydration chamber through distillation and said water and said air are used for flushing.
7. The apparatus of claim 3, wherein said waste cleaning means include one or more blades disposed within said dehydration chamber to clean the sides and bottom of said chamber.
8. The apparatus of claim 2, further comprising an air compressor and an air motor to blow the dried waste into said receptacle.
9. The apparatus of claim 6, further comprising a heat sensor to discern between steam and dry heat in order to control said dehydration process.
10. The apparatus of claim 3 wherein\'the size of said dehydration chamber is sufficient to hold multiple deposits of waste.
11. The apparatus of claim 3 wherein said dehydration chamber includes one or more ports.
12. The apparatus of claim 3 wherein said dehydration chamber includes four ports, one for waste entry, one for air intake, one for venting and one for waste exit.
13. The apparatus of claim 2 further comprising one or more one way valves.
14. The apparatus of claim 13 wherein said one way valves are balls which dissolve and deodorize during venting.
15. The apparatus of claim 14 wherein said balls can be made from quick lime, chlorine, camphor or other material used in urinals and the like.
16. The apparatus of claim 6 wherein energy used in said dehydration process is about 0.5 kW.
17. The apparatus of claim 2 wherein said toilet is self- contained and the same size as most water toilets.
18. The apparatus of claim 2 wherein a vacuum or suction can be used to send the waste to a remote central holding location.
19. The apparatus of claim 8 wherein the compressor intake comes from said toilet bowl and is activated by a weight sensor switch when weight is applied to said bowl.
20. The apparatus of claim 3, wherein said toilet bowl and said dehydration chamber can be separated from the rest of the apparatus and placed in a remote location.
21. The apparatus of claim 6 wherein said dehydration process uses cooling coils to distill steam and reclaim water for flushing.
22. The apparatus of claim 2 further comprising antifreeze to be used either alone or in addition to said liquid to prevent freezing and aid in distillation reclamation.
23. A method of safely disposing of human waste without water consumption or chemicals, which electrically produces a dry powdered waste product, comprising the steps of: providing a toilet bowl; directing air and liquid into said bowl to clean said waste; transferring said waste into a dehydration chamber; deodorizing and drying said waste via a dehydration process; and recovering said dried waste within a receptacle.
24. The method of claim 23 further comprising the step of controlling said dehydration process via the use of a temperature sensor.
25. The method of claim 23 wherein said liquid is water and said water is reclaimed from said dehydration process occurring within said dehydration chamber through distillation.
26. The method of claim 23 further comprising the step of blowing the dried waste into said receptacle via the use of an air compressor and an air motor.
27. The method of claim 23 further comprising the step of discerning between steam and dry heat in order to control said dehydration process via the use of a heat sensor.
28. The method of claim 23 wherein said waste is removed to a remote central holding location via the use of a vacuum or suction.
29. The method of claim 23 further comprising the step of providing an air compressor and an air motor to blow the dried waste into said receptacle.
30. The method of claim 29 wherein said compressor intake comes from said toilet bowl and is activated by a weight sensor switch when weight is applied to said bowl.
