排水機器の排水配管、及び排水トラップ

Drain pipe for draining device, and drain trap

Abstract

【課題】 洗濯機・洗面台・流し台・浴室など排水機器の排水配管において、排水や泡の逆流、排水による騒音の発生等を防止・制限するようにする。 【解決手段】 洗濯機・洗面台・流し台・浴室など排水機器の排水を処理する排水配管において、排水配管の流路中に、略筒体状にして可撓性を有する素材からなり、筒体の一部において内面同士が当接することで筒体が閉塞し、筒体の一方へ流れようとする流体の圧力に対して弾性変形して筒体内部を開口して流体を通過させると共に、筒体の他方へ流れようとする流体の圧力に対しては閉塞した状態を維持して流体の通過を防止する自封装置(1)を備えて構成する。 【選択図】図5
PROBLEM TO BE SOLVED: To provide a drain pipe for a draining device including a washing machine, a wash stand, a sink, and a bathroom, the drain pipe preventing or reducing the occurrence etc. of backflow of drainage and bubbles, and noise caused by the drainage. SOLUTION: The drain pipe for disposing of drainage of the draining device including the washing machine, the wash stand, the sink, and the bathroom, has a self-sealing device 1 arranged in a channel thereof. The self-sealing device 1 is formed like an almost cylindrical shape, made of a flexible material, blocks a cylinder body by abutting both inner surfaces on each other at a location of the cylinder body. The self-sealing device is elastically deformed against pressure of fluid flowing in one direction of the cylinder body, and opens the interior of the cylinder body to allow the fluid to pass therein. On the other hand the self-sealing device maintains a closed state against the pressure of the fluid flowing in the other direction of the cylinder body, to thereby prevent the fluid from passing therein.
