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.

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.

A combination toilet and urinal device. The device includes a tank having a toilet chamber configured to house flushing water with the toilet chamber in fluid communication with a toilet bowl through a toilet chamber discharge port. The tank further includes a urinal chamber that is separated from the toilet chamber. The urinal chamber includes a urinal chamber inlet extending through an exterior surface of the tank for receiving urine in the urinal chamber and delivering the urine to a urinal chamber collection pipe without delivering the urine to the toilet bowl. The device further includes a flushing system configured to flush both the toilet bowl and the urinal chamber collection pipe through the same toilet bowl outlet pipe. Thus, the device is designed to help conserve water by allowing a user to use the urinal feature between toilet uses without flushing.

The present disclosure relates to the technical field of daily necessities, and provides a urinal, a squatting pan and a pedestal pan. The special urinal comprises a urinal, a sewage discharge port, a water inlet and a water outlet hole. The urinal has a first end adjacent to the sewage discharge port and a second end away from the sewage discharge port; the sewage discharge port is provided at the bottom of the urinal, the water outlet hole is communicated with the water inlet, the urinal is internally provided with a protruding portion that is used for being opposite to the anus of a user; one end of the protruding portion extends to the bottom of the urinal; and the water outlet hole is used for flushing the protruding portion. The present disclosure aims to solve the defect in the prior art that a female urinal cannot distinguish stool from urine. By providing the protruding portion, in the case of conforming to women's toileting habits, a stool avoidance function is achieved, and a user is prevented from defecating, thus achieving the purpose of women's urination. By using the special urinal, a female public lavatory can be provided with a stool area and a urine area, thus improving the overall toileting efficiency, reducing the number of people in a queue, and shortening the queuing and waiting time.

A flush toilet includes a toilet main body made of ceramics and a control unit. The toilet main body includes a skirt, and a rear storage that can store at least a part of the control unit, the rear storage includes a supporting wall that divides a storage region into upper and lower regions and that supports the control unit, the skirt forms a double wall including an outer wall and an inner wall, the double wall has at least a part that forms an internal space between the outer wall and the inner wall, and the skirt includes a single wall in which the internal space of the double wall is removed in an upper end above a joining portion between the double wall and the supporting wall.
