Abstract
A gravity drop-toilet uses main water via electronically programmed valves to rinse separate areas of a bowl (,) in sequence via appropriately located and pointing jet orifices (,) with about 70% less water than siphon toilets. Electronically timed valve (,) hydraulically causes a pair of bellows (,) 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 (,). The linkage comprises a transfer arm (,) that pivots a rotating arm of a cup (,) and flap actuating arm (,) to pivot a springy plate (,) upward against a dimple (,) formed on under the side of the flap (,) which thereby aligns itself against the bottom edge (,) of the bowl (,). A urine version of this mechanism uses apertures (,) that they enclose combine to center defecating sitters over a cylinder outlet (,) of the bowl. These parts and apertures prevent waste from smearing the seat, rim, and back of the bowl. Water valves (,) and (,) respectively respond to hand plungers,and,so that the toilet also works during an electric power outage. The toilet is programmable and more user friendly.
