A flush toilet of the present invention includes a bowl including a waste receiving surface that receives waste, a rim formed on an upper part of the waste receiving surface and a well portion that is formed below the waste receiving surface and in which a pooled water surface is formed, one or more spouting ports that spout flush water along the rim, and a discharge conduit connected to a bottom portion of the bowl, the flush toilet including a configuration where a forward main flow F1 and a rearward main flow F2 of flush water spouted from the spouting ports circulate around a waste receiving surface 16 of a bowl 6 and flow, in the beginning of flushing start, into three or more regions of the pooled water surface divided into four regions S1, S2, S3 and S4.

A flush toilet according to the present invention includes a bowl including a bowl-shaped waste receiving surface, a rim, a spouting port formed in the rim and a pooled water portion having a front region and a rear region, and includes a configuration where a ratio of an inflow flow rate of flush water into the front region of the pooled water portion in a second half of flushing period in a flushing period to “a total inflow flow rate of flush water into the pooled water portion” is larger than a ratio of an inflow flow rate of flush water into the front region of the pooled water portion in a first half of flushing period to “the total inflow flow rate of flush water into the pooled water portion”.

A toilet includes a bowl with a sump and a trapway connecting the sump to an outlet of the toilet. The trapway has a zeta shape and is configured to induce a siphon which provides pressure to suction waste water from the bowl during a flush cycle. A trapway supply conduit is connected to the trapway in a tangential orientation to an upleg region of the trapway. The trapway supply conduit supplies water to the trapway, which follows a contour of the inner surface of the trapway supply conduit and continues in the same direction into the upleg region of the trapway by relying on a fluid flow to follow the curve of a convex surface placed proximate to the flow.

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.

A toilet assembly includes a toilet body and a nozzle system. The toilet body defines a toilet bowl and a rim area disposed along an upper edge of the toilet bowl. The rim area includes a flange defining an opening. The nozzle system includes a nozzle having a first end configured to be fluidly coupled to a water supply conduit and a second end fluidly coupled to the rim area. The second end defines an outlet formed at a compound angle. The connector assembly detachably couples the nozzle to the flange such that the nozzle extends through the opening.

A flush toilet includes a bowl part and a water storage part. The bowl part receives waste. The water storage part is formed on a bottom of the bowl part and stores a stored water. The water storage part includes a front surface part, a back surface part that is formed on a back side of the front surface part, and a pair of side surface parts that are formed between the front surface part and the back surface part. On at least one side surface part in the pair of side surface parts, a convex surface that protrudes toward another side surface part is formed.

A flush toilet according to an embodiment includes a bowl part, a rim part, a water spout port, and a water storage part. The bowl part receives waste. The rim part is formed on a top of the bowl part. The water spout port spouts a washing water from one side of the bowl part in leftward and rightward directions. The water storage part is formed on a bottom of the bowl part. The bowl part includes a guide part that causes the washing water to swirl from the one side to another side that is opposite to the one side and causes the washing water that swirls to the another side to flow into a back side of the water storage part.
