    Abstract: A flush toilet includes a bowl part that includes a waste-receiving surface with a bowl shape that receives waste and a rim part that extends upward on an upper edge part of the waste-receiving surface, a first water-spouting port that spouts a washing water toward the rim part to form a first flow of a washing water that swirls on the waste-receiving surface, a second water-spouting port that spouts a washing water toward the rim part to form a second flow of a washing water that joins the first flow, and a connection part that includes a concave surface that connects the waste-receiving surface and the rim part and is curved to have a curvature that decreases from an upstream side to a downstream side of the first flow just before the first water-spouting port or the second water-spouting port in a flow direction of the first flow.

    Abstract: A flush toilet is capable of suppressing water from splashing from a bowl at a time when water is discharged rearward inside the bowl from one rim spout port portion formed in a rim portion. A rim spout portion of the flush toilet forms a rim water passage where flush water that is supplied flows through, and forms, on a downstream end of the rim water passage, a rim spout port portion that discharges the flush water rearward. The rim spout port portion, which is one in number, is formed in the rim portion, and the rim spout port portion in the linear portion is formed to discharge water rearward in the bowl in a direction extending the linear portion.

    Abstract: A flush toilet of present invention includes a bowl that includes a bowl-shaped waste receiving surface, a rim formed above the waste receiving surface, and a pooled water portion formed below the waste receiving surface, a discharge passage that has an inlet connected to the pooled water portion and discharges waste, and a spout portion that spouts flush water onto the bowl and forms a swirling flow on the waste receiving surface. The waste receiving surface of the bowl has a sectorial recess that is formed between a front end portion of the waste receiving surface and a front end portion of the pooled water portion so as to spread from the pooled water portion toward the front end portion of the waste receiving surface.

    Abstract: A rimless toilet pan (20) including a forward end (F), a rearward end (R), a pan bowl (28), a flushing outlet (32), a flushing water inlet (30), an inwardly facing first sidewall (34), an inwardly facing second sidewall (37) and a flushing water flow splitter (38). The flushing outlet (32) is in fluid communication with the pan bowl (28). The flushing water inlet (30) is in fluid communication with the pan bowl (28). The inwardly facing first sidewall (34) extends substantially around the top of the pan bowl (28). The substantially horizontal ledge (36) extends substantially around the bottom of the first sidewall (34). The inwardly facing second sidewall (37) extends substantially around the pan bowl (28) under the horizontal ledge (36). The flushing water flow splitter (38) is substantially adjacent a rearward end of the first sidewall (34), is in fluid communication with the flushing water inlet (30) and has a leftwards outlet (38a) and a rightwards outlet (38b). The flushing water flow balancer (40) is on a frontwards part of the first sidewall (34), includes an inwardly facing projection (40a/b/c) extending vertically through at least part of the height of the first sidewall (34) and is positioned substantially symmetrically in relation to a forward to rearward centerline (42) of the toilet pan (28).

    Abstract: 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.
