Abstract
An air activated toilet flush system, including: a toilet bowl; a reservoir; a fluid conduit between the reservoir and the toilet bowl; a system for supplying water into the reservoir; and a system for supplying air into the reservoir, wherein a supply of air into the reservoir causes fluid to flow from the reservoir through the fluid conduit and into the toilet bowl.
Claims31
An air activated toilet flush system, comprising:
- a toilet bowl;
- a reservoir;
- a fluid conduit between the reservoir and the toilet bowl;
- a system for supplying water into the reservoir;
- and
- a system for supplying air into the reservoir, wherein a supply of air into the reservoir causes fluid to flow from the reservoir through the fluid conduit and into the toilet bowl.
3 more elements
A toilet, comprising:
- a toilet bowl;
- a tank attached to the toilet bowl;
- a water reservoir within the tank and containing a predetermined volume of water;
- a riser conduit having an upper end above the surface of the predetermined volume of water and a lower end extending below the surface of the predetermined volume of water;
- a spillway providing a path for fluid flow between the upper end of the riser conduit and the toilet bowl;
- an air inlet conduit with an outlet inside the water reservoir above the surface of the predetermined volume of water;
- a source of pressurized air connected to the air inlet conduit;
- and
- a flush actuator associated with the source of pressurized air, wherein when the flush actuator is activated, pressurized air flows through the outlet of the air conduit into the water reservoir above the surface of the predetermined volume of water, thereby pressurizing the water reservoir and forcing at least a portion of the predetermined volume of water up the riser conduit, through the spillway and into the toilet bowl.
6 more elements

- a toilet bowl;
- a reservoir;
- a fluid conduit between the reservoir and the toilet bowl;
- a system for supplying water into the reservoir;
- and
- a system for supplying air into the toilet bowl, wherein a supply of air into the toilet bowl to pushing the waste out of the bowl first and then fluid can fill in bowl after causes fluid to flow from the reservoir through the fluid conduit and into the toilet bowl.
