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 bowl has a closed jet pathway to maintain the jet channel in a primed state with fluid from the jet flush valve assembly to prevent air from entering the closed jet pathway. Flush valves may have back-flow preventer mechanisms and/or at least partly flexible valve covers, including specific valve cover structures. Flush activation assemblies may have a flush activation bar connected to the pivot rod and/or an adjustable flush connector located between the pivot rod and the flush activation bar. A kit providing one or more flush activation elements is included. The kit elements may be usable with the toilet systems and methods described.

摘要： The object of the present invention is to provide a washdown flush toilet which can maintain effective waste discharging performance even with a relatively smaller amount of flush water.
The present invention is a washdown flush toilet including: a bowl part configured to receive waste, and a water discharge trap conduit connected to a lower portion of the bowl part. The water discharge trap conduit includes: an inlet pipe part whose one end is continuous or connected to the lower portion of the bowl part; a trap ascending pipe part whose one end is continuous or connected to the other end of the inlet pipe part and which forms an ascending flow channel; and a trap descending pipe part whose one end is continuous or connected to the other end of the trap ascending pipe part and which forms a descending flow channel. With regard to a cross section perpendicular to a flow direction of the ascending flow channel, a portion on a downstream side of the ascending flow channel is provided with an enlarged part which has a cross section area larger than that on an upstream side of the ascending flow channel. A downstream end of the ascending flow channel and/or an upstream side of the descending flow channel is provided with a shrunk part which has a cross section area smaller than that on the upstream side of the ascending flow channel.

摘要： A flush toilet according to the embodiment includes a main water guide channel, a downstream-side water guide channel, and a convex part. Through the main water guide channel, flush water supplied from a water supply source flows. The downstream-side water guide channel on a downstream side of the main water guide channel spouts the flush water from a water spout port of the downstream-side water guide channel. The convex part is formed in the downstream-side water guide channel. The convex part includes a first guide part that guides upward the flush water flowing through the downstream-side water guide channel, and a second guide part on a downstream side of the first guide part which guides downward the flush water.

摘要： A flush toilet according to an embodiment includes a main water guide channel, a bending water guide channel, a rim water guide channel, and a retention part. The bending water guide channel bends a flow direction of washing water supplied from the main water guide channel. The rim water guide channel causes the washing water to flow toward and to be spouted from a water spout part. The retention part is formed in at least the bending water guide channel. An upper part of the retention part is formed into an opened concave shape and the retention part retains a part of the washing water. Furthermore, the retention part is formed in such a manner that an upper end thereof on a downstream side is horizontal to a bottom surface of the water spout part or higher than the bottom surface of the water spout part.

摘要： A flush toilet includes: a bowl including a rim formed on the top edge of a bowl-shaped waste receiving surface, a discharge path connected to the bottom of this bowl for discharging waste, and a rim spout portion disposed on this rim for spouting flush water within the bowl to form a circulating flow. The bowl further includes a shelf, formed in the circumferential direction from the rim spout portion between the waste receiving surface top edge and the rim bottom end, for guiding flush water spouted from the rim spout portion in the circumferential direction. The rim spout portion is disposed on either the left or right of either the side region or the front region of the bowl, and forms a rim spout port to spout flush water rearward. The width of the shelf is set to decrease from the side to the rear of the bowl.
