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： This invention relates to a cistem (1010): More specifically, the invention relates primarily to concealed cisterns for toilets having integrated, and preferably adjustable, dual-flushing and odour extraction capability. The cistem (1010) includes a primary chamber (1020) for storing a volume of liquid, a liquid inlet (1026) for the primary chamber (1020) of the cistem (1010) with liquid, an air outlet (1028) for exhausting air from the primary chamber (1020) of the cistem (1010) operatively during filling; and a liquid outlet (30) through which liquid operatively stowed in the primary chamber (1020) of the cistem is dischargeable. The cistem (1010) further includes a fill valve for controlling liquid supply into the primary chamber from the liquid inlet (1026) and a flush valve (60) for controlling flow through the liquid outlet (30). The flush valve (60) comprises of a flush valve seat and a flush plug (1064) being moveable relative to the flush valve seat between an open position, wherein the flush plug (1064) is displaced from the flush valve seat thereby to open the liquid outlet (30) and enable the liquid in the primary chamber (1020) to discharge there through during flushing, and a closed position, wherein the flush plug (1064) is seated on the flush valve seat thereby to close the liquid outlet (30) and prevent the passage of liquid there through. The cistern (1010) also includes at least one actuator (1070) for actuating displacement of the flush plug (1064) from the closed position to the open position, and a controller (1123) for controlling one or more of a group of flushing conditions including: (i) flush type, wherein the cistem (1010) is adjustable between a single flush, dual-flush, on-demand flush or a combination of such flush type conditions; and (ii) flush time, wherein the time of the displacement of the flush plug (1064) by the actuator (1070) for each flush type condition is adjustable.

摘要： A touchless actuation system for a toilet includes a touchless sensor, a motor assembly, and a processing circuit. The touchless sensor is located within a closed reservoir of the toilet. The processing circuit is configured to receive a signal from the touchless sensor and to detect an object within a detection region based on the signal. The detection region is external to the closed reservoir. The processing circuit is configured to facilitate flushing of the toilet through interaction with the motor assembly when the object is detected.

摘要： A system for preventing overflow of a toilet includes a capacitance sensor arrangement as in combination with certain features (e.g., flap valve disablement). The system can detect an overflow flush condition of a toilet by sensing the value of a parameter of one or more normal flush cycles of the toilet and establishing a normal range for the value of the parameter using the sensed value. The system can also store the normal range in a memory for comparison to a value of the parameter during subsequent flush cycles. The system can perform sensing over a predetermined timeframe. The system can include the time frame being sufficient to include the entire push cycle of the toilet.
