To provide a siphon drainage structure capable of suppressing stagnation of drainage in plumbing fixtures.SOLUTION: A siphon drainage structure 10 includes: a siphon drain pipe 58 provided with a horizontal draw pipe member 60 that allows drainage from a wash basin 22 to flow laterally, a drop pipe 64 connected to the horizontal draw pipe member 60, and a rigid pipe member 68 connected to the drop pipe 64; and a drain trap 28 provided with a first bent part 36 disposed between the horizontal draw pipe member 60 and a drain port member 24 of a wash basin 22, and stores sealed water SW, and a second bent part 38 provided on the downstream side of the first bent part 36 in a drain direction. When a first height difference between a drainage inlet of the drain port member 24 and an upper end 38T of the second bent part 38 measured in the vertical direction is A, and a height difference between a bottom 36B of the internal flow path of the first bent part 36 and the upper end 38T of the curved portion inside the radius of curvature in the internal flow path of the second bent part measured in the vertical direction is B, the ratio A/B is set to be 380% or more.SELECTED DRAWING: Figure 1
【課題】水廻り器具に排水が滞留することを抑制可能なサイホン排水構造を提供する。【解決手段】サイホン排水構造１０は、洗面台２２からの排水を横方向に流す横引き管部材６０と、横引き管部材６０に接続される落し込み管６４と、落し込み管６４に接続される竪管部材６８と備えるサイホン排水管５８と、横引き管部材６０と洗面台２２の排水口部材２４との間に配置され、封水ＳＷを貯留する第１屈曲部３６と第１屈曲部３６の排水方向下流側に設けられる第２屈曲部３８とを備えた排水トラップ２８と、を有し、鉛直方向に沿って計測する排水口部材２４の排水流入口と第２屈曲部３８の上端３８Ｔとの第１の高低差をＡ、鉛直方向に沿って計測する第１屈曲部３６の内部流路の底部３６Ｂと第２屈曲部の内部流路における曲率半径内側の湾曲部分の上端３８Ｔとの高低差をＢとしたときに、比Ａ／Ｂを３８０％以上に設定している。【選択図】図１
