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

A flush toilet of present invention includes a bowl that includes a bowl-shaped waste receiving surface, a rim formed above the waste receiving surface, and a pooled water portion formed below the waste receiving surface, a discharge passage that has an inlet connected to the pooled water portion and discharges waste, and a spout portion that spouts flush water onto the bowl and forms a swirling flow on the waste receiving surface. The waste receiving surface of the bowl has a sectorial recess that is formed between a front end portion of the waste receiving surface and a front end portion of the pooled water portion so as to spread from the pooled water portion toward the front end portion of the waste receiving surface.

Flush toilet

A flush toilet and a drain socket are provided that align the direction of waste passing through a drainage trap so as to prevent pipe clogging without impairing wastewater discharge performance by a siphon effect. The drain socket is for connecting an outlet of a trap drainage channel of a flush toilet unit and a drain pipe located external of the flush toilet unit. The drain socket includes a drain socket body provided with an inlet for coupling with the trap drainage channel and an outlet for coupling with the drain pipe, a siphon inducing region provided on an inner wall of the drain socket body for inducing a siphon effect, and a straightening vane provided upstream of the siphon inducing region of the drain socket body to extend from the inner wall in the inward direction of the channel.

Drain socket and flush toilet

A flush toilet that uses a prescribed amount of cleansing water stored in a cleansing water tank to cleanse the toilet and discharge waste is disclosed. The flush toilet includes a bowl having a waste receiving surface, an overhanging rim and a shelf, a drainage channel whose inlet is connected to the bottom of the bowl for discharging waste, a first water spouting section for spouting cleansing water onto the shelf of the bowl to form a vortex; a second water spouting section for spouting cleansing water onto shelf of the bowl in the same direction as the swirling direction of the vortex, a first water channel for supplying cleansing water from the cleansing water tank to the first water spouting section, and a second water channel for supplying cleansing water from the cleansing water tank to the second water spouting section.
