Abstract
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.
