The present disclosure provides a water supply assembly of a toilet comprising a water input pipe, a water tank, a water suction pump and a water output pipe; wherein the water input pipe is connected to the water tank; clean water enters the water tank through the water input pipe; the water tank is connected to the water suction pump connected to the water output pipe; the water suction pump pumps the clean water inside the water tank into the water output pipe; the water tank comprises a main water tank portion, an auxiliary water tank portion, and a water equalizing pipe connecting between and through the main water tank and the auxiliary water tank. The present disclosure provides a flushing assembly, a water suction assembly, and a check valve for use in the toilet. The present disclosure provides a method, device, and storage for controlling toilet water consumption.

A flush toilet includes a toilet main body and a control unit. The toilet main body includes a skirt, a rear storage configured to store at least a part of the control unit, and an opening to which a drain pipe is connected is formed penetrating, in a front-rear direction, a portion below a center in a left-right direction of a rear wall of the skirt. The rear storage forms a discharge socket storage on a front side of the opening in a region below a center of the rear storage in the left-right direction. And a side wall surface in the discharge socket storage protrudes more in a center direction of the opening than a side wall surface in the opening, to reduce an opening cross-sectional area of the discharge socket storage to be smaller than an opening cross-sectional area of the opening.

The present disclosure relates to a water supply mechanism of a toilet, comprising: a water tank configured to store water; a discharge valve configured to discharge the water in the water tank when the discharge valve is opened and configured to keep the water in the water tank when the discharge valve is closed; a vacuum breaker disposed in the water tank and connected to the discharge valve, the vacuum breaker configured to allow air to enter the discharge valve; a discharge pipe, comprising a gravity discharge channel and a power discharge channel both in fluid communication with the discharge valve and both configured to supply the water in the water tank to a jet hole when the discharge valve is opened; and a discharge power unit in fluid communication with a downstream of the discharge valve and connected to the power discharge channel.

The present invention provides a flush toilet device (1) including: a flush toilet (2); a flush water tank (10); a discharge valve (12) that discharges the flush water stored in the flush water tank; a branching portion (33) that splits flush water supplied from a water supply source into first and second branched flow paths; a first on-off valve (19) provided in the first branched flow path and switches between spout and stop of the flush water from the upper spout port; a second on-off valve (17) provided in the second branched flow path and switches between supply and stop of the flush water into the flush water tank; and a controller (28) that controls the first and second on-off valve so that water is spouted from the upper spout port and is supplied into the flush water tank at a time by opening the first and second on-off valves.

The present invention provides a flush water tank device (4), including: a flush water tank (10); a discharge valve (12) that causes the lower spout port to eject the flush water by switching between discharge and stopping of the flush water; a water pressure driving mechanism (14) that drives the discharge valve with a water supply pressure; a first on-off valve (19) that switches between water ejection and stopping of the flush water; a second on-off valve (18) that switches between water supply and stopping of the flush water to the water pressure driving mechanism; and a delay valve opening mechanism (21) that causes the second on-off valve to open with a delay of predetermined time after water ejection from the upper spout port is started, using a part of the flush water introduced via the first on-off valve, to supply the flush water to the water pressure driving mechanism.

A flush toilet in which a comparatively large storage region that stores a functional unit can be formed in a region in more rear side than a bowl of a toilet main body, while improving designability of the whole flush toilet is provided. A toilet main body of a flush toilet includes a skirt and a rear function storage portion, the skirt includes an opening, the opening being formed in a portion of an upper part of an outer wall of the skirt, the opening allowing the rear function storage portion inside the skirt to open toward outside the skirt, and a part of the functional unit stored in the rear function storage portion forms an outer surface to close the opening.

A flush toilet of the present invention includes: a bowl including a waste receiving surface, a rim and a shelf surface, the shelf surface of the bowl including linear portions formed on a right side and a left side, a front arc portion connected to front ends of the linear portions, and a rear arc portion connected to rear ends of the linear portions; a rim spout portion spouting flush water to the shelf surface to form a circulating flow; and the like. Flush water is spouted backward from the rim spout port along the linear portions of the shelf surface; and the shelf surface and the waste receiving surface are coupled by an inner coupling portion, and a curvature radius of the inner coupling portion along a vertical direction is set to a smaller value on a rear end of the bowl than on a front end thereof.

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.

A flush toilet is provided, which can enhance discharge performance of waste from an inside of a water discharge trap conduit even with a smaller amount of flushing water, in the flush toilet discharging waste by a siphon action. A flush toilet of the present invention has a bowl section, a water discharge trap conduit, and a jet spout port connected to a lower portion of the bowl section and opened toward the water discharge trap conduit, with an outlet portion bottom surface of an outlet portion thereof and a bottom surface of the bowl section being connected, and a bottom surface of the bowl section forms a curved surface that diagonally inclines more downward than the outlet portion bottom surface from a tip end of an outlet portion bottom surface of the jet spout port.

A flush toilet is provided, which can advance timing for startup of a siphon action that discharges waste, and can efficiently discharge waste from a water discharge trap conduit. A flush toilet of the present invention has a bowl section, a water discharge trap conduit connected to a lower portion of the bowl section, and a jet spout port that is opened toward the water discharge trap conduit, in the lower portion of the bowl section, and the jet spout port includes an outlet flow path in which a bottom surface extending toward an outlet of the jet spout port and toward a bowl section bottom surface in the lower portion of the bowl section, and a ceiling surface extending toward the outlet and having an inclination toward an upper direction than an inclination of the bottom surface are formed.
