A toilet includes a toilet bowl assembly having a toilet bowl and a trapway extending from the bottom of the toilet bowl to a sewage line. The toilet bowl has a rim channel provided along an upper perimeter portion thereof. In this toilet, the flush water flows through the rim channel in a path which is asymmetric and unidirectional along the entire perimeter portion thereof. The rim channel includes a plurality of rim openings distributed evenly along the perimeter of the rim channel. Flush water passing through the plurality of rim openings pre-wets the entire perimeter of the toilet bowl. The rim channel further includes a pair of water discharge slots which directs water directly into the toilet bowl in two powerful streams. The flush valve allowing passage of water from the water tank to the toilet bowl assembly is in the form of a valve inlet having a radiused port to generate greater energy throughput of the flush water.

A gasket assembly includes an upper housing forming a seal with the outlet of a bathroom fixture, and a lower housing forming a seal with a sewer pipe. The lower housing has an outer surface extending along an axis and a toroidal gasket disposed in sealing relationship with the outer surface and the sewer pipe. To accommodate larger sewer pipes, the outer surface can be formed on an adapter and a second gasket provided to form a seal with the adapter. In an associated method for mounting the gasket assembly, the gasket is rolled axially in a continuous sealing relationship with the lower housing.

A potting training device for preventing a potty-training child's urine stream from passing through the opening formed between the toilet seat and the toilet bowl. The device is made of a flexible, water-resistant, preferably non-porous sheet material, having a folding seam separating a urine-deflecting surface and a plurality of attachment tabs. An adhesive material is applied to the surface of each attachment tab and attaches the attachment tabs to the underside of the toilet seat. The sheet material, in its unattached flat configuration, is manipulated into a curved configuration that matches the curvature of the toilet seat, and is attached thereto. The potty training device is also not visible to the observer unless the toilet seat is lifted up, in a vertical position or viewed from a position to the rear of the attachment point when the toilet seat is down.

A self-cleaning flooring system for catching waste products has at least one module comprising a drain pan and a floor grid. The drain pan has a ramp and a central drain outlet. The ramp extends around the drain pan defining a drain pan periphery. The ramp slopes downward from the drain pan periphery towards the drain outlet. The drain pan periphery has a plurality of discharge ports spaced therealong for discharge of flushing fluid onto the ramp such that the waste products are washed down the ramp towards the drain outlet. The floor grid extends across the drain pan and is mounted upon the drain pan periphery for supporting personnel standing thereon while permitting waste products to pass therethrough. The module is interconnectable to horizontally adjacent modules to form the flooring system.

The invention discloses a water-saving, uneasily blocked and automatic high pressure flush closet, which relates to the field of closets. When no person sits on the closet, a pipeline port is sealed by a closet piston and a stable sealing pipe. When a person uses the closet, tap water enters a water spray elastic rubber pipe; after the person leaves, water stored in the rubber pipe is sprayed out under triple force of restoring force of the rubber pipe and restoring force and transferred tap water pressure of the closet; the water enters a water spray inner shaft pipe from a water tank of the closet; the piston and a cylinder at the pipeline port of the closet move downwards under water pressure, and water is started to be sprayed out from a water spray hole of the cylinder; the water also flows into a pump chamber; a sandwich layer shaft pipe rotates along with an impeller; the water also enters a water spray pipeline of a closet body and an upper part of a water spray outer shaft pipe; and the water spray pipe of the closet and the water spray hole in the closet cylinder are used for rotatablely spraying the water to the inner wall of the pipeline, the water spray hole in the pipeline of the closet body is used for spraying the water to the rotating closet piston, water spray pipe and cylinder. Excrement is fed into a sewer under the action of centrifugal force and sprayed water. The closet finishes flushing.

The present disclosure generally relates to improved water closet flanges and methods for installing such water closet flanges. In one exemplary embodiment, an improved water closet flange apparatus includes an outer flange and a flexible conduit portion (i.e. sleeve) extending downwardly therefrom. The flexible sleeve has a sufficient degree of flexibility to accommodate connection between offset, misaligned, angled, or otherwise incongruous plumbing fixture discharges and waste drain pipe outlets. In one embodiment, the flexible sleeve includes at least one corrugated portion to aid the desired flexibility. An upper portion of the flexible sleeve may include an inwardly extending lip portion to accommodate the desired seal between the plumbing fixture discharge and the flange apparatus. Related methods for installing the disclosed flange apparatus between plumbing fixture discharges and waste drainpipes are also described.

An improved water closet flange for connection to a plumbing fixture is described. The improved flange comprises an anchoring element or outer flange, connected to a flexible conduit tube or flexible sleeve, in which is attached an O-ring type of gasket. The improved flange connects a toilet bowl outlet to a waste drainpipe outlet without any flow reduction in between both connecting elements. The improved flange allows the connection between a toilet bowl discharge and a well placed vertical waste drainpipe. The improved flange also allows the connection between a toilet bowl discharge and a waste drainpipe outlet that is offset, horizontally oriented, or diagonally placed. The improved flange may further comprise an O-ring type of gasket disposed on the exterior of the flexible sleeve to provide a tight seal between the outer surface of the flexible sleeve and the inner surface of a waste drainpipe. The flexible sleeve can be implemented in a variety of sizes or diameters, including, for example, 3 inch (7.5 cm) and 4 inch (10 cm) diameters. An alternative embodiment of the flexible sleeve can fit either 3 inch or 4 inch drainpipes with the help of an appropriate O-ring seal of the appropriate dimensions.

A flush toilet that uses a prescribed amount of cleansing water stored in a cleansing water tank to cleanse the toilet and discharge waste is disclosed. The flush toilet includes a bowl having a waste receiving surface, an overhanging rim and a shelf, a drainage channel whose inlet is connected to the bottom of the bowl for discharging waste, a first water spouting section for spouting cleansing water onto the shelf of the bowl to form a vortex; a second water spouting section for spouting cleansing water onto shelf of the bowl in the same direction as the swirling direction of the vortex, a first water channel for supplying cleansing water from the cleansing water tank to the first water spouting section, and a second water channel for supplying cleansing water from the cleansing water tank to the second water spouting section.
