Mechanically sealable rapid opening stagger-flush residential toilet

Abstract

A frustum-shaped toilet bowl (26) includes a reversibly rotable saucer-shaped seal (46), or saucer. The saucer can automatically be rotated upward hermetically to compress closed against a sealing ring (48) that surrounds the outside of the bowl near its bottom outlet (32). The saucer is normally closed to prevent sewer gases from entering a bathroom from an adjoining drain line (36). The closed saucer can retain human waste or test balls in the bowl or, when opened, permits them to free-fall of their own weight into the drain line. The bowl has opposing water outlets (42) which are connected to flushometer valve (34), which is connected to a source of pressurized water. Depressing a button (74) automatically provides a wet spot in the bowl to prevent falling feces from sticking to the bowl. Depressing the button a second time opens the saucer and causes additional water to stagger flush solids while they are moving in the pipe. A two-stage staggered flush propels solids further than releasing the wet spot water and the additional water into the pipe together. A urine flush uses about 250 ml (0.25) gallons and a feces flush about 4.0 liters (1.0 gallon) of water. A 2.00 to 3.00-liter (0.50- to 0.75-gallon) flush carries 100 test balls about 18.2 meters (60 feet) in the drain line.

AI Technical Summary

Problems solved by technology

However, water evaporates.

Furthermore, significant pressure or suction in an adjoining drain line can undo a water seal, so that those nearby are no longer protected from sewer gases.

Parts of the inside of a bowl, the cup, and the waste passageway have been severely corroded by urine, feces, and sewer gases.

Axial seals that surround a shaft that pivots the cup have been severely damaged by corrosion Thus, potentially toxic and or explosive volatile sewer gases can jeopardize the health and welfare of those nearby.

Water is less than optimal.

However, the only water available in an RV, when it is not hooked up to an external source of water, is that which it carries.

Many children and invalids cannot rinse and flush them.

Consequently, most people cannot open the valves fast enough to permit human waste and water in the bowls to free fall.

They are less than optimal.

The mechanism that opens the sealing blade cannot open it fast enough to permit bowl contents to free fall.

It is less than optimal.

Feces are prone to adhere to the concavities, convexities, or angles that characterize such bowls.

Thus, such bowls are more prone to require multiple rinses.

Such bowls are less than optimal.

However, the spillways are too close to water outlets.

However, since water evaporates water seals can completely evaporate.

MaP-rated toilets are less than optimal because they are not a true measure of a toilet's ability to flush feces without clogging a convoluted waste passageway.

Some fecal forms can readily clog the waste passageway of a siphon toilet that sausages readily transit.

As shown below, a one-stage flush is less than optimally water-saving.

Reservoirs and waste treatment plants can be vast and costly, according to Residential End Use of Water: Indoor Water Use, www.waterwiser.org.

It can cost as much to enlarge a water storage reservoir as to build one.

Current toilets are not optimal for reducing such financial burdens.

The toilets substituted in Los Angeles in 1999, as well as today's more water-saving ones, are less than optimal for reducing the numerous new, or enlarged, water reservoirs and waste treatment plants which the U.S. needs today, and is projected to need for the foreseeable future, or for saving taxpayers billions of dollars.
