A flush toilet includes a bowl including a waste receiving surface, a rim and a well portion; a water spouting part that spouts flush water toward the bowl; and a water discharge trap including an inlet connected to a lower part of the well portion, the water discharge trap discharging waste in the bowl, the well portion includes a bottom wall formed above and in front of the inlet of the water discharge trap, a side wall formed to surround a periphery of the bottom wall, and a joining portion that joins an outer edge of the bottom wall and a bottom edge of the side wall with a surface having a curvature, and the bottom wall of the well portion includes a concave portion formed to recess downward on left and right sides with respect to a center axis in a left-right direction in a front sectional view.

Flush toilet

The flush toilet of the present invention includes a bowl which receives waste; and a discharge trap conduit which is connected to a lower portion of the bowl and extends to a discharge opening connected to an inlet of an external discharge pipe and a part of which stores sealing water. The discharge trap conduit includes: an ascending conduit which ascends rearward from the lower portion of the bowl; and a descending conduit that descends from a downstream end of the ascending conduit to the discharge opening. The descending conduit includes a bottom surface on the rear side of the discharge opening and a guiding portion formed on the bottom surface which guides the wastewater flowing horizontally from the bottom surface toward the discharge opening to be directed to either a left or right side of the center of the discharge opening.

A flush toilet of the present invention includes a bowl portion for receiving waste and a discharge trap conduit connected to a lower portion of the bowl portion and extending to a discharge opening. The discharge trap conduit includes an ascending conduit ascending rearward from the lower portion of the bowl portion and a descending conduit descending from a downstream end of the ascending conduit to the discharge opening. The descending conduit includes a bottom surface on a rear side of the discharge opening, and a ceiling sloping surface, an upper end of the ceiling sloping surface being formed integrally with a bottom surface of a top portion of the ascending conduit, the ceiling sloping surface being formed on a front side of the discharge trap passage, and the ceiling sloping surface being inclined downward and forward from the upper end to a lower end of the discharge trap passage.

A toilet according to an embodiment includes a toilet body and a water drainage socket. The toilet body has a water drainage outlet on a back surface thereof. The water drainage socket connects the water drainage outlet and an inlet of a water drainage pipe that is provided on a wall surface. The back surface of the toilet body is provided with an opening and a guide part. The opening is provided to insert therethrough a tubular member that extends from the wall surface in a case where the toilet body is mounted on the wall surface. The guide part guides the tubular member that is provided in a state where it is inserted through the opening so as to move to an outer side of the water drainage socket in a case where the toilet body is mounted on the wall surface.

Toilet and toilet apparatus

The present invention is a discharge socket connecting a toilet main body and a discharge pipe. The discharge socket has a vertical conduit portion; and a bent conduit portion including an inflow port connected to the vertical conduit portion; an outflow port, connected to an inlet port of the discharge pipe; and a flow path, the flow path having a bent portion. A projecting portion is disposed on the bent portion, the projecting portion forming a projecting space which projects outward from the flow path. The projecting portion is formed so that the flow direction of discharge water flowing from the bent conduit portion into the inlet portion of the discharge pipe is changed to the center direction of the discharge pipe by the discharge water returning to the projecting space after flowing from the flow path into the projecting space.

Discharge socket and flush toilet having same

Problem: Provided is a flush toilet capable of increasing the volume of a waste conveyance flow, thereby improving a waste conveyance capability. Solution: The flush toilet includes: a toilet main unit () comprising a discharge conduit () communicated with the discharge trap pipe. The discharge conduit includes a flow dividing section () provided on a downstream side of an upstream discharge conduit section, and a delaying flow passage () branched from the flow dividing section. An inward region of the skirt portion includes: a central region (D) and a lateral region (E). The delaying flow passage () forms a passage in the lateral region (E) and merges leading flush water having flowed into the delaying flow passage from the flow dividing section () with a flush water flow reaching the flow dividing section at a timing after the inflow of the flush water to the delaying flow passage.

Provided is a flush toilet capable of increasing the volume of a waste conveyance flow for washing down waste thereby improving a waste conveyance capability. The flush toilet includes: a discharge conduit () communicated with the discharge trap pipe. The discharge conduit includes: a flow dividing section () and a delaying flow passage () branched from the flow dividing section. The flow dividing section has a guide portion () configured to guide relatively low-speed flush water along the guide portion to the delaying flow passage. The delaying flow passage () is configured such that flush water having flowed into the delaying flow passage along the guide portion () is enabled to merge with a flush water flow reaching the flow dividing section at a timing after the inflow of the flush water to the delaying flow passage.
