Abstract: A toilet having a water inlet structure, a bowl structure, a rim, and an outlet structure. The water inlet structure is configured to receive water from a water source. The bowl structure includes a toilet bowl and a water channel, which is fluidly connected to the water inlet structure and is configured to feed water into the toilet bowl from an outlet of the water channel that is located between a back portion and a side portion of the toilet bowl. The rim has a solid, annular member disposed around a top of the toilet bowl and entirely above the water channel, is formed separately from and coupled to the bowl structure. The outlet structure is fluidly connected to the toilet bowl to carry the water and contents from the toilet bowl to an outlet.

Abstract: A vortex flush toilet includes a toilet stool including a toilet bowl and a rim unit, a water tank unit, a first water discharge unit, a pipe unit, an electric switching valve, and a sensor control unit controlling switching of the electric switching valve between a blocked state and a communicated state. The rim unit is formed with first, second, and third flushing ports having decreasing sectional area, and has first, second, and third water-guiding passages respectively in fluid communication with the first, second, and third flushing ports and each having a width decreasing gradually. A bottom surface of each of the first, second, and third water-guiding passages has a height decreasing gradually and forms a respective one of first, second, and third height differences increasing gradually. An inclination angle defined between the bottom surface of each first, second, and third water-guiding passage and a horizontal line gradually increases.

Abstract: The present invention relates to a toilet comprising an open-rim toilet bowl which combined construction elements generate a unique combination, the implication of which is obtaining a performance that balances the capacity to evacuate solid waste and light floating load while inside the sanitary ware, in addition to the ability to drag waste through the drainage line. In the same way, the toilet of the present invention is intended to minimize the loss of hydraulic potential supplied to it during the flushing action, from the entrance of water through the inlet tray towards a set of flushing ports located in the rim and windows that direct the water in a specific manner, generating a combined effect of floating and inertial release of the heavy load into the well, facilitating the progressive entry of the load into the discharge channel for its evacuation. Thus, said toilet maximizes the result of the previously defined effect, by providing a balance between the formal attributes of a flush action toilet.

Abstract: 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.

Abstract: A toilet assembly includes a toilet body and a fluidic oscillator. The toilet body defines a toilet bowl that is configured to receive a volume of fluid therein. The fluidic oscillator is coupled to the toilet body in a rim area of the toilet bowl. The fluidic oscillator is positioned to direct a fluid onto an inner surface of the toilet bowl. The fluidic oscillator is configured to continuously redirect the flow of fluid to different locations along the inner surface of the toilet bowl.

Abstract: A rimless toilet pan (20) includes a forward end (F), a rearward end (R) and a pan bowl (28). A flushing outlet (32) is in fluid communication with the pan bowl (28). A flushing water inlet (30) is in fluid communication with the pan bowl (28). An inwardly facing first sidewall (34) extends substantially around the top of the pan bowl (28). A substantially horizontal ledge extends (36) substantially around the bottom of the first sidewall (34). An inwardly facing second sidewall (37) extends substantially around the pan bowl (28) under the horizontal ledge (36). A flushing water flow splitter (38) is substantially adjacent a rearward end of the first sidewall (34), the flow splitter (38) is in fluid communication with the flushing water inlet (30) and has a leftwards outlet (38a) and a rightwards outlet (38b). A flushing water flow balancer (40) is on a frontwards part of the first sidewall (34), the flow balancer (40) including an inwardly facing projection (40a, 40b, 40c) extending vertically through at least part of the height of the first sidewall (34) and being positioned substantially symmetrically in relation to a forward to rearward centreline of the toilet pan (20). The flow balancer (40) includes leftward (40a) and rightward (40b) angled surfaces which meet at an innermost edge (40c) that is substantially aligned with the forward to rearward centreline of the toilet pan (20). The leftward (40a) and rightward (40b) angled surfaces are substantially triangular in shape and taper from a relatively wide lower part to a narrowed or pointed upper part.

Abstract: A toilet bowl unit includes a toilet bowl with an inner toilet bowl surface having an upper peripheral portion, a central peripheral portion and a lower sump portion. A peripheral slot separates a lower edge of the upper peripheral portion from an upper edge of the central peripheral portion. A peripheral water channel is concealed inside the toilet bowl unit and has a side wall which is a weir over which water may flow into the peripheral slot. The slot has a discharge opening which is substantially horizontal at the rear and sides of the inner toilet bowl surface (for discharging a curtain of water) and includes at least one serpentine portion at the front of the inner toilet bowl surface (for discharging a jet of water). The horizontal portion(s) of the discharge opening are positioned just below a seat platform surface in order to minimize the unwashed area at the top of the inner toilet bowl surface.

Abstract: This flush toilet apparatus includes a traveling-direction switching mechanism switching a mode between a toilet washing mode and a tank storage mode. This traveling-direction switching mechanism includes: a shield portion directing jet water to an outside of a throat pipe at a time of the tank storage mode; a moving mechanism moving the shield portion from a position at a time of the toilet washing mode in a first direction to a position at the time of the tank storage mode; and a guide surface switching a traveling direction of the jet water so that after the traveling direction is switched, a flow rate of the jet water is higher in a second direction opposite to the first direction than in the first direction.
