Abstract
(EN)
Provided is a drain structure, comprising: a tub (first water-use area apparatus) in which drainage is reservoir drainage that is drained after storage; a wash place (second water-use area apparatus) in which drainage is continuous drainage without storage; a first drain trap provided to a drain part of the tub; a second drain trap provided to the wash place; a first bypass pipe connecting a drain pipe (downstream-side site) of the first drain trap and a drain pipe (downstream-side site) of the second drain trap, at least a portion of the pipe line of the first bypass pipe being positioned above both the first drain trap and second drain trap; a first siphon drain pipe connected to the downstream side of the first bypass pipe and the first drain trap; and a second siphon drain pipe connected to the downstream side of the first bypass pipe and the second drain trap.
(FR)
La présente invention concerne une structure de drain, comprenant : une cuve (premier appareil de zone d'utilisation d'eau) dans laquelle un drainage est un drainage de réservoir qui est drainé après le stockage ; un lieu de lavage (second appareil de zone d'utilisation d'eau) dans lequel le drainage est un drainage continu sans stockage ; un premier siphon prévu sur une partie de drainage de la cuve ; un second siphon prévu sur le lieu de lavage ; un premier tuyau de dérivation reliant un tuyau de drain (site côté aval) du premier siphon et un tuyau de drain (site côté aval) du second siphon, au moins une partie de la ligne de tuyau du premier tuyau de dérivation étant positionnée au-dessus à la fois du premier siphon et du second siphon ; un premier tuyau de drainage de siphon relié au côté aval du premier tuyau de dérivation et du premier siphon de drainage ; et un second tuyau de drainage de siphon relié au côté aval du premier tuyau de dérivation et du second siphon de drainage.
(JA)
排水構造は、排水が、貯水後に排水される溜め流し排水となる浴槽(第1の水廻り器具)と、排水が、貯水のない連続排水となる洗い場(第2の水廻り器具)と、浴槽の排水部に設けられた第1排水トラップと、洗い場に設けられた第2排水トラップと、第1排水トラップの排水管(下流側部位)と第2排水トラップの排水管(下流側部位)とを接続し、管路の少なくとも一部が第1排水トラップ及び第2排水トラップの双方よりも上方に位置する第1バイパス管と、第1排水トラップ及び第1バイパス管の下流側に接続された第1サイホン排水管と、第2排水トラップ及び第1バイパス管の下流側に接続された第2サイホン排水管と、を有する。
