    摘要: 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.

    摘要: 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.

    摘要: 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 tank, a flush valve, and a rim in fluid communication with the bowl through a rim flow path from an outlet of the flush valve to at least one rim outlet port. The flush valve is configured to operate in a flush actuation mode wherein the flush valve is able to provide flush water flow sufficient for the toilet assembly to initiate a flush siphon or provide a wash down flush and to operate in a cleaning actuation mode wherein the flush valve is only partially opened to allow for introduction of a cleaning agent and flush water mixture to the bowl that is insufficient to initiate a siphon but sufficient for cleaning the bowl. The cleaning system includes a reservoir for a liquid cleaning agent, a housing for the reservoir, a supply conduit for receiving fluid from within the reservoir and delivering it to a flush valve, a flow control device capable of controlling flow of cleaning agent and a control system activatable by an actuator feature to initiate a clean cycle by operating the flow control device to deliver a dose of cleaning agent to one or more rim outlets, and operating the flush valve in cleaning actuation mode to introduce flush water to carry the dose of cleaning agent through the at least one rim outlet port into the toilet bowl at a flow rate insufficient to initiate a siphon but sufficient for cleaning the bowl.

    摘要: 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.

    摘要: 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.
