Low Flush Toilet with Bowl Venting

Abstract

A sanitary toilet employs a soft flat tube at the outlet neck at the outlet of the toilet bowl. This soft flat tube extends through the drain opening into the sanitary drain to permit passage of waste into the sanitary sewer drain. A water inlet pipe produce a water spray or jet into the bowl, and a valve limits the flow of water to about 0.3 to 1.0 liters per use. The toilet has a vent inlet within the toilet bowl beneath the seat, a blower that induces a flow of air into the vent inlet, and an exhaust conduit from the blower that discharges to a vented space outside the bathroom. The unit may be formed of a micrite material.

Description

BACKGROUND OF THE INVENTION [0001]This invention is directed to sanitary toilets, and is in particular concerned with toilets that have a reduced water consumption as compared with traditional siphon-type flush toilets, and is also concerned with toilets that can vent off bathroom odors before they escape from the toilet bowl.[0002]Typically, modern toilets have a tank that holds a quantity of water (six liters to sixteen liters) and which discharges the water quickly into the toilet bowl to cause the bowl to siphon and flush away the urine, feces, or other waste matter in the bowl.[0003]This type of toilet is notorious for wasting water, both during the flush and through leakage from the tank past leaky flush valves.[0004]The flushing operation causes the water to flow past a trap to reduce the static hydraulic pressure, to suck the water in the bowl past the trap, and into the sewer drain pipe. This consumes a minimum of about six liters of water, and in some toilets as much as si...

AI Technical Summary

Benefits of technology

[0009]Accordingly, it is an aspect of this invention to provide a sanitary toilet with significantly reduced water consumption, and which avoids the drawbacks of the prior art.

[0010]Another object is to provide a toilet of simple construction which allows the waste matter to pass to the sewer drain, but does not allow malodorous sewer gases to rise from the sewer drain pipe.

[0011]A further object is to provide a sanitary toilet which avoids water wastage from dripping or leaking out of the toilet tank.

[0016]For a durable, and stain resistant product, which is economical to manufacture, the toilet bowl and other components may be compression molded of a micrite stone material.

Problems solved by technology

Another object is to provide a toilet of simple construction which allows the waste matter to pass to the sewer drain, but does not allow malodorous sewer gases to rise from the sewer drain pipe.
