Abstract: The present invention provides a toilet using a cyclone-type sewage purifier, which can discharge excrement using a small amount of water and can sanitarily treat the discharged excrement using waste water, thus increasing the efficiency with which the waste water is recycled. The toilet includes a toilet bowl having a depression; a refuse pipe passing through the toilet bowl and connected to the depression, thus guiding the discharge of excrement from the depression; a refuse bowl seated in the depression and temporarily holding the excrement, and discharging the excrement into the refuse pipe when it is rotated; a rotating device for rotating the refuse bowl; and a cyclone-type sewage purifier for executing purification treatment using a vortex generated by descent of the excrement and waste water discharged from the refuse pipe and a waste water pipe.

Abstract: A portable toilet (12) is provided having a bowl (14), a seat (16), legs (20), and wheels (28) mounted to the legs (20). The legs (20) are spaced apart and telescopically extensible to allow positioning of the bowl (14) above a conventional building toilet (60). The bowl (14) has a lower end (48) defined by sections (50) which pivot to open the bowl (14) and allow the contents to spill therefrom into the conventional toilet (60). A liner (34) fits in the bowl (14) and is held in place by the seat (16). The bowl (14) is placed over the conventional building toilet (60), the lower end (48) of the bowl is opened, the seat (16) is raised, and then the liner (34) and its contents fall through the open lower end (48) of the bowl (14) and into the conventional toilet (60).

Abstract: A toilet has an electronic flush assembly operable in either a short or long flush sequence selectable by a user. The long flush sequence includes a pre-rinse cycle and a rinse cycle in which the a supply valve and a flush valve are both opened and closed twice, once each first during the pre-rinse cycle and again during a subsequent rinse cycle. The rim supply valve and the flush valve are opened during the pre-rinse and rinse cycles but are closed at the start and end of each cycle. An electronic control controls operation of the valves as well as water supply control components. Level sensors can also be included to provide feedback to the controller, for example, to prevent overflow conditions.

Abstract: Tilting Bowl Toilet comprises a frame, a toilet basin, and a tilting bowl. The tilting bowl is supported below the toilet basin to receive and hold water/waste delivered from the toilet basin. The tilting bowl tilts to discharge its content to drainage. The tilting bowl at standby is sustained to stay in a horizontal position by a sustaining turning moment about its support axis. When water is added, the turning moment produced by the tilting bowl with its content becomes larger than the sustaining turning moment, and the tilting bowl moves to a tilted position to discharge its content. As the tilting bowl tilts, the sustaining turning moment is simultaneously reduced to accelerate bowl tilting for efficient discharge of waste to sewage.

Abstract: A flush mechanism for use in a urinal. The flush mechanism includes a flush reservoir pivotally mounted within a flush frame. The flush mechanism receives water from an inlet above the flush reservoir. The flush reservoir is pivotable from a fill position to a flush position whereby the water is dispensed to a manifold within the urinal for flushing of the urinal. The flow of water into the flush reservoir and the actuation of the flush reservoir may be directed by a controller.

Abstract: A gravity drop-toilet uses main water via electronically programmed valves to rinse separate areas of a bowl (71) in sequence via appropriately located and pointing jet orifices (136, 138,140) with about 70% less water than siphon toilets. Electronically timed valve (180) hydraulically causes a pair of bellows (110) to compress and expand and thereby reversibly pivot a mechanical linkage to retain waste in the bowl and drop waste via a vertical waste passageway into a sewer pipe (30). The linkage comprises a transfer arm (118) that pivots a rotating arm of a cup (128) and flap actuating arm (104) to pivot a springy plate (78) upward against a dimple (80) formed on under the side of the flap (30) which thereby aligns itself against the bottom edge (74) of the bowl (71). A urine version of this mechanism uses apertures (174, 175) that they enclose combine to center defecating sitters over a cylinder outlet (48) of the bowl.

Abstract: A toilet including a frame defining a chamber, a toilet bowl disposed within the chamber between an upper and a lower chamber region, and a tilting bowl in the lower chamber region of the frame. The toilet bowl in the lower discharge opening in communication between the upper and lower chamber regions. The tilting bowl defines a fluid-receiving volume, and is mounted for pivoting movement relative to the toilet bowl between a first position with the fluid-receiving volume at least partially overlapping the toilet bowl and containing the lower discharge opening, and a second position permitting flow of fluid from the toilet bowl, through the lower discharge opening, and from the fluid-receiving volume into the lower chamber region. At standby, the tilting bowl, in the first position, retains a first volume of fluid sufficient to engage the lower discharge opening and restrict flow of gas therethrough.

Abstract: To eliminate the necessity of a water tank, this invention converts the traditional toilet bowl with siphonic water trap into a toilet basin with a tilting-bowl. The toilet includes a frame, a toilet basin, a tilting bowl and a trigger means. The tilting bowl is mounted to pivot as a movable water/waste container. In its not tilted horizontal position, the tilting bowl receives and holds water/waste delivered to it through the toilet basin. When the tilting bowl tilts, it discharges its content to drainage pipe through a bottom discharge hole; simultaneously allowing water/waste to discharge from basin to drainage. The tilting bowl is normally retarded to stay in its horizontal position by forces applied to the tilting bowl creating a resultant retarding turning moment about its pivot point larger than the turning moment produced by the tilting bowl with its content.

Abstract: A flush toilet primarily for use in recreational homes and vehicles is described. A swing drop valve mechanism is used to open and close the outlet of the toilet bowl efficiently and without abrading the seal between the valve and bowl outlet. A flush water inlet valve is mounted in a compartment at the rear of the toilet for easy access for maintenance and is readily removable from the toilet using a minimum of tools. Flushing of the toilet is initiated by a foot pedal connected to the valve mechanism and water inlet valve by cables.

Abstract: Toilet apparatus that has a plurality of improved features including: a sealing mechanism for closing the bottom opening of a toilet bowl so that the effectiveness of the seal is maintained over extended periods of time, a flushing circuit that has a water reservoir that assures proper depth is achieved in the pool of water that is formed after the sealing mechanism is closed, an over flow tube which assures that the water seal therein is maintained, and a control valve which has an inlet fitting that assures that damage to the valve or related parts does not occur during installation of the toilet apparatus.

Abstract: A bottom discharge toilet in which a trap is formed integrally with the toilet base. While the trap plays no role in the flushing action of the toilet itself, it is adapted to receive the discharge from other plumbing fixtures and thereby to serve as a single, common trap for such fixtures. By directing the received discharge through the interior of the toilet, the trap also assists in keeping the toilet outlet line clear. To further reduce the overall cost, the toilet is formed in several interlocking pieces as a kit which can be conveniently shipped and handled, and then assembled on-site. A novel water inlet valve operates in cooperation with a flushing mechanism to clear the toilet and refill the bowl with a minimum of water consumption.

Abstract: An improved sanitary water closet wherein the soil pipe leading to the sludge tank, passes through a flushing container and is formed inside the latter with a bend provided with grid means arranged to allow passage through of liquid into the container and further to a septic tank, but to divert solid material to the sludge tank. Because of the separation of liquid and solid products, the sludge product obtained in the sludge tank contains very little moisture and is therefore easily biologically degradable.
