A skirted toilet assembly, comprising a toilet bowl having a sump outlet; and a wall extending around the bowl from a first rear edge to a second rear edge; wherein the wall, the first rear edge, and the second rear edge define a space within the wall, the sump outlet is configured to couple to a trapway, the trapway is configured to fluidly couple the sump outlet with a sewer outlet, and the trapway is configured to be disposed within the space. A trapway may be a thermoplastic and the sump outlet a ceramic.

Toilet assembly

A toilet assembly comprising a toilet tank; a flush valve assembly positioned in the tank; a bowl; and a trapway, wherein the flush valve assembly comprises a flush valve body extending from a flush valve inlet to a flush valve outlet; a canister having a seal positioned at a lower end and a closed upper end; and a conduit positioned in an interior of the canister, wherein the seal is configured to enclose the flush valve inlet, the canister is configured to lift from the flush valve inlet to open the valve to initiate a flush cycle, the canister comprises one or more openings configured to provide flow communication between the canister and the tank, and the conduit is coupled to the trapway and provides for flow communication between the canister and the trapway.

Flush valve and toilet assembly

A siphonic flush toilet system and method of priming the same having a toilet bowl assembly comprising at least one jet flush valve assembly and at least one rim valve; and bowl having a rim and a jet defining at least one jet channel. The bowl has a closed jet pathway to maintain the jet channel in a primed state with fluid from the jet flush valve assembly to prevent air from entering the closed jet pathway. Flush valves may have back-flow preventer mechanisms and/or at least partly flexible valve covers, including specific valve cover structures. Flush activation assemblies may have a flush activation bar connected to the pivot rod and/or an adjustable flush connector located between the pivot rod and the flush activation bar. A kit providing one or more flush activation elements is included. The kit elements may be usable with the toilet systems and methods described.

Primed jet toilet

A method and system having a water-flush toilet having a toilet bowl that is in fluid communication with a water source and is mounted with a sensor. The sensor includes a transmitter to transmit an ultrasonic signal and a receiver to receive an ultrasonic signal. The sensor may measure a Time of Flight (ToF) of the signal to obtain a ToF measurement. A microcontroller is electrically connected to the sensor and may receive and process the ToF measurement using an algorithm to determine a bowl status. The toilet also includes at least one water valve that is disposed between the bowl and the water source, and that is electrically connected to the microcontroller for instructing the at least one water valve to move from a first position to a second position for a duration of time, wherein the duration of time corresponds to the bowl status.

Systems to monitor a toilet bowl and to determine a bowl status

A siphonic flush toilet system and method of priming the same having a toilet bowl assembly comprising at least one jet flush valve assembly and at least one rim valve; and bowl having a rim and a jet defining at least one jet channel, the at least one jet channel having an inlet port and a jet outlet port configured for discharging fluid to a sump area, wherein the sump area is in fluid communication with a trapway. The bowl has a closed jet pathway including the jet channel and extending from the jet flush valve assembly outlet to the jet channel outlet port to maintain the jet channel in a primed state with fluid from the jet flush valve assembly so as to assist in preventing air from entering the closed jet pathway. Flush valves are also disclosed having back-flow preventer mechanisms and/or at least partly flexible valve covers for use with the toilet systems and methods herein.

Toilet assemblies having various embodiments of a cleaning system are described herein which include a toilet assembly and a cleaning system. The toilet assembly has a toilet bowl, a toilet tank, a flush valve, a rim inlet port and a rim flow path (which may be an isolated rim path) extending from an outlet of the flush valve to the rim inlet port. The cleaning system has a reservoir for holding a liquid cleaning agent having an outlet port in fluid communication with the interior space of the reservoir body; a housing to receive the reservoir, a supply conduit in fluid communication with the interior of the reservoir; a flow control device capable of controlling flow through the supply conduit; and a control system activatable by an actuator feature, wherein upon activation of the actuator feature, the control system is adapted to initiate a clean cycle by: operating the flow control device for a first period of time sufficient to deliver a dose of a liquid cleaning agent from the supply conduit to an interior space of the flush valve in a closed position, the flush valve configured for delivery of fluid to the rim inlet port, and operating the flush valve to open the flush valve to introduce flush water to carry the dose of a liquid cleaning agent through the rim inlet port into the toilet bowl.

Self cleaning toilet assembly and system

Cartridge

An elevated flush valve comprising a vent cover may be used with various assemblies, particularly for high efficiency and high performance toilets, which vent cover has a wall that includes an upper portion, a lower portion configured to define a vent cover inlet opening for receiving air and/or liquid passing upwardly from within a valve body and/or from within a toilet through a toilet inlet when the vent cover is installed on a valve body, an exterior surface, and an interior surface defining a vent cover passage for air passing upwardly from the vent cover inlet opening. At least the upper portion of the vent cover wall is configured for contacting an interior surface of a valve body at a location above an inlet of an overflow or venting tube on a valve body when the vent cover is installed on a valve body and wherein the valve cover wall is configured to at least partially divert flow of fluid from entering an inlet of an overflow tube or a venting tube on a valve body when the vent cover is installed on a valve body.

Systems to automate adjustment of water volume release to a toilet bowl to correspond to bowl contents, toilets including the system and related methods

Toilet assemblies having various embodiments of a cleaning system are described herein which include a toilet assembly and a cleaning system. The toilet assembly has a toilet bowl, a toilet tank, a flush valve, a rim inlet port and a rim flow path (which may be an isolated rim path) extending from an outlet of the flush valve to the rim inlet port. The cleaning system has a reservoir for holding a liquid cleaning agent having an outlet port in fluid communication with the interior space of the reservoir body; a housing to receive the reservoir; a supply conduit in fluid communication with the interior of the reservoir; a flow control device capable of controlling flow through the supply conduit; and a control system activatable by an actuator feature, wherein upon activation of the actuator feature, the control system is adapted to initiate a clean cycle by: operating the flow control device for a first period of time sufficient to deliver a dose of a liquid cleaning agent from the supply conduit to an interior space of the flush valve in a closed position, the flush valve configured for delivery of fluid to the rim inlet port, and operating the flush valve to open the flush valve to introduce flush water to carry the dose of a liquid cleaning agent through the rim inlet port into the toilet bowl.

A wall hung toilet is described which has a toilet body having a toilet body inlet, a back plate having at least a first and a second lower fastener opening therethrough, a toilet body outlet, a bowl and a base. The bowl has an interior surface defining a interior area for receiving fluid, an inlet for introducing fluid to the interior area of the bowl and a bowl outlet. A trapway for passing fluid from the bowl outlet to the toilet body outlet is also included. The base of the toilet body extends from a front bowl portion of the base to a rear portion of the base that contacts the back plate, and the base is configured so as to distribute load bearing forces when applied to the bowl in use towards each of a first area around the first fastener opening and a second area around the second fastener area.
