A toilet fixture is provided including an inlet pipe, a toilet bowl in fluid communication with the inlet pipe, an outlet pipe in fluid communication with the toilet bowl, a jet pipe in fluid communication with the inlet pipe and the outlet pipe, and a removable jet pipe assembly that connects the jet pipe to the outlet pipe. A foreign object strainer may be positioned in-line with the inlet pipe. A flush assembly may also include a flush valve, a vacuum breaker tube in fluid communication with the flush valve, a foreign object strainer in fluid communication with the vacuum breaker tube, and an outlet pipe in fluid communication with the foreign object strainer.

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.

An unpowered automatic flushing module for a flush valve having an integrated flushing opening/closing portion is proposed. The module controls time to dispose of toilet paper with feces and flushing of the feces while suctioning air from outside through a toilet paper time adjustment part when a toilet user defecates and leaves a toilet seat, and controls time to dispose of the toilet paper with urine and flushing of the urine so as to flush an amount of water for urination while rapidly suctioning the air from the outside through the toilet paper time adjustment part and a urine flushing adjustment part when the toilet user urinates and leaves the toilet seat, thereby preventing the toilet user from wasting the water by unnecessarily pressing a lever. In addition, the flushing opening/closing portion is integrated into a module of a detection switch instead of fixing to the toilet seat separately.

A powerless automatic flushing device is proposed. The device controls flushing of feces and time to dispose of toilet paper with feces while suctioning air from outside through a feces toilet paper time adjustment part and a flushing adjustment part when a toilet user defecates and leaves a toilet seat, and respectively controls the flushing of urine and time to dispose of toilet paper with urine while rapidly suctioning the air from the outside through each of a feces toilet paper time adjustment part, a flushing adjustment part, and a urine toilet paper time adjustment part when the toilet user urinates and leaves the toilet seat, thereby preventing the toilet user from wasting the water by unnecessarily pressing a lever, and a tension load spring compresses in conjunction with descending motion of the toilet seat and retains a tension load force capable of pulling a flushing wire.

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 flush toilet includes a toilet main body made of ceramics and a rear storage configured to store at least a part of a control unit. The rear storage includes a supporting wall that divides a storage region into upper and lower regions and that joins left and right side walls of the skirt and the water discharge trap. The supporting wall includes a horizontal wall that extends in a horizontal direction from a joining portion between the supporting wall and the water discharge trap, and left and right lower walls that are provided outside the horizontal wall in a left-right direction and below the horizontal wall and that are joined to the left and right side walls of the skirt. The left and right lower walls on a rear side are separated in the left-right direction by the horizontal wall.

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.

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 which is capable of suppressing reduction in the force of water and disturbance in the flow curved by a pressure loss caused by a flow curved separating from a surface on an inner side portion side of an intermediate part. A rim water passage of the flush toilet includes a curved portion that is curved inward from a downstream end of an outer side portion. The curved portion includes a top portion that is at a position farthest from the intermediate part in the top view, in a direction extending the intermediate part. The top portion is formed in more the outer side portion side than a virtual center line that extends along a center of the intermediate part.
