    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 trip lever assembly for a toilet includes a body and an infrared sensor. The body is configured to be mechanically coupled to a flush valve assembly of the toilet. The infrared sensor is coupled to the body, and is configured to be electrically coupled to the flush valve assembly. The body is configured to be manually actuated to control the flush valve assembly. The infrared sensor is a time-of-flight sensor configured to detect the distance of an object in a detection region of the infrared sensor to control the flush valve assembly.

    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 flushing apparatus (1, 301) for being installed in the cistern of a toilet including a flushing device (2) for fluid connection with an outlet of a cistern and a hydraulically-driven control circuit (3, 303) for operating the flushing device. The control circuit (3, 303) includes a water inlet (P) for fluidly connecting the control circuit (3, 303) to a source of pressurised water and an accumulator (6) fluidly connected to the water inlet (P) and configured to supplement, in use, the flow of pressurised water supplied by the source trough the control circuit (3, 303) to activate the flushing device (2).

    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.

    摘要: A volume controllable toilet flush system, comprising: a cistern configured to hold and retain a fluid; a vertically moveable siphon assembly comprising a siphon portion, a pipe and at least one resilient element attached to the pipe; a toilet bowl shaped to retain and hold waste; an actuator operatively connected to the pipe by a stud attached to the pipe and configured to provide vertical movement to the siphon assembly, wherein movement of the siphon assembly by the actuator stores or releases energy in the at least one resilient element and, wherein downward vertical movement of the siphon assembly puts the toilet bowl in fluid communication with the cistern by creating a siphoning action between the siphon portion and the fluid in the cistern and wherein subsequent upward vertical movement of the siphon assembly terminates the siphoning action to stop fluid flow from the cistern to the toilet bowl.
