Waterless Toilet System with Fece-Urine Separation, Odor and Vermin Seal, Thermal and Biological Disinfection, and Gas Ozonation

Abstract

A waterless toilet system with fece and urine separation, odor and vermin seal, thermal and biological disinfection, and gas ozonation includes a system of components. The feces and urine are kept separate by a ridge separating the urine bowl from the fece chute. The seat forms a temporary seal with the platform, and the lid forms a temporary seal with the seat when closed. The rest of the components are sealed to keep vermin outside and odors inside, with the exception of a gas vent hose with a screened opening. Biological disinfection is achieved with phage focused on human pathogens. Thermal disinfection of human pathogens is achieved by insulating the fece receptacle and containing metabolic heat. The air in the toilet is ozonated by electrical discharges from a hand operated device.

Description

FIELD OF THE INVENTION[0001]The present invention is in the field of sanitary equipment, and more particularly, waterless toilet systems that keep feces and urine separate. Our definition of ‘waterless toilet’ means that the toilet operates without the addition of external water i.e. the only water in the toilet is the water latent in the urine and feces.BACKGROUND OF THE INVENTION[0002]Two and a half billion people in the world in 2010 do not have toilets. They rely on open defecation and open urination and in some cases, they use open latrines. Small children exposed to the ubiquitous feces can get dysentery and die, in fact, 1.3 million do so each year. Mosquitoes, flies, bugs, birds, and rats feed on the open latrines and unburied feces, then spread the viruses and bacteria to people through bites, stings, and contact with the human food supply. Diseases worse than dysentery are spread this way, too, for example the deadly Cholera and Typhoid fever.[0003]These poor people cannot...

AI Technical Summary

Benefits of technology

This patent describes a waterless toilet system that separates urine and feces, reducing the risk of disease and odor. The toilet system is sealed from the surrounding environment when closed, preventing vermin from entering. The toilet system also uses a thermally insulated receptacle to kill bacteria and prevent odor. Additionally, the toilet system reduces odors inside by using an ozonator to break down odorous gases. Overall, this patent provides a technical solution for a safer, odor-free toilet.

Problems solved by technology

These poor people cannot afford toilets with plumbing, water, or chemical disinfectants.

They have no electricity, piped water, or piped sewage disposal, and very little money.

Even the waterless toilet of this invention is too expensive for these poor people and will require subsidies from aid agencies and charities.

Where it lands is the problem.

Though splattering on the roofs and walls of other shanties or on pathways is most common, occasionally it hits a pedestrian.
