TOILET STOOL HAVING SIPHON TUBE

摘要

A toilet equipped with a siphon pipe is provided to allow the press pipe to be expanded or contracted uniformly without hanging on the exterior wall and to raise the siphon pipe with a small-elasticity spring. A toilet comprises a bowl(10), a variable siphon pipe(140) which is arranged behind the bowl and is connected to move up and down along with up-and-down movement of a press pipe, and the press pipe(120) of bellow type which is arranged behind the variable siphon pipe. The top of the press pipe is installed on an opening(14) of a water supply passage(12) and the bottom is equipped with a press pipe support(122). A spring(124) is mounted inside the press pipe so that the press pipe is expanded when filled with water and raised when the water is evacuated. A press pipe case(126) of telescope type foldable in the vertical direction is installed around the press pipe and serves as guide member to allow the press pipe to move up and down without interfering with the exterior wall.
