Abstract: A toilet includes a bowl with a sump and a trapway connecting the sump to an outlet of the toilet. The trapway has a zeta shape and is configured to induce a siphon which provides pressure to suction waste water from the bowl during a flush cycle. A trapway supply conduit is connected to the trapway in a tangential orientation to an upleg region of the trapway. The trapway supply conduit supplies water to the trapway, which follows a contour of the inner surface of the trapway supply conduit and continues in the same direction into the upleg region of the trapway by relying on a fluid flow to follow the curve of a convex surface placed proximate to the flow.

Abstract: A toilet having a tank to receive water and a bowl connected with the tank. Water travels from the tank to the bowl to discharge waste in the bowl through a manifold connected to the bowl and into a drain line. The toilet has a jet trapway portion having a jet inlet with a nozzle connected with the tank. The nozzle directs water from the jet inlet to overcome an upward bend in the jet trapway portion until received by the manifold at an inlet below the upward bend. A waste trapway portion extends from the manifold opposite the jet trapway portion and connects with the drain line. Waste is discharged from the bowl through the manifold over a bend in the waste trapway portion by combining water flowing from the jet trapway portion into the manifold with waste flowing from the manifold into the waste trapway portion.

Abstract: A flushing toilet has a manually operable main discharge valve with a main flushing outlet connected to a flushing outlet below the normal water level in a toilet bowl water trap. The flushing outlet is directed toward the water trap. A generally tangential swirling outlet in an upper region of the toilet bowl is controlled by a separate valve and directed generally horizontally to cause water leaving it to follow a swirling path on the inside of the toilet bowl in a cleansing flush. The water trap has a passage that follows a path of generally squat U-shape with an inlet end opening into the lower end of the toilet bowl, a central region that is lowermost and a water trap outlet the lowermost part of which defines a depth to the water trap. The cross-sectional shape of the passage has a longer vertical axis than its horizontal axis.

Abstract: A helical drain for a toilet is disclosed. The present invention relates to a novel toilet drain configuration. Specifically, the novel toilet drain configuration comprises a helical loop trapway. The drain of the present invention exits the toilet bowl and forms a substantially vertical tubular loop running generally parallel to the width of the bowl or stool, or perpendicular to the longitudinal axis of the bowl or stool, before being connected to a sewer. The drain of the present invention functions like a P-trap syphon in removing the contents of the bowl. The diameter of the looped tubular portion of the drain may vary by approximately 20 percent or less in the direction of the sewer connection. Sensors may be placed on the drain to monitor drain contents, fluid levels, and drain performance. The drain may be fitted with valves to control the flow of fluids and gases through the drain.
