DRAINAGE MEMBER AND DRAINAGE SYSTEM
To provide a drainage member and a drainage system capable of improving drainage capacity while enabling miniaturization.SOLUTION: A drainage member 5 constitutes a part of a drainage system having a vertical pipe 3 and a horizontal pipe 4. The drainage member 5 has a first opening 5a directed to the upstream side of the drainage system, a second opening 5b directed to the downstream side of the drainage system, and a bent flow passage 5c connecting the first opening 5a and the second opening 5b so that central axes C1, C2 of the first opening 5a and the second opening 5b intersect with each other. A first wall surface 50b on the inner peripheral side of the bent flow passage 5c protrudes toward a second wall surface 50c on the outer peripheral side of the bent flow passage 5c so that a reduced part 5c1, where the cross-sectional area of the bent flow passage 5c becomes smaller than the cross-sectional area of the second opening 5b, is located between an angle 5d on the inner peripheral side of the bent flow passage 5c and the second opening 5b. When the diameter of the second opening 5b is d and the length of the reduced part 5c1 in the direction of the central axis C2 of the second opening 5b is L, 0.5d≤L≤5.0d is satisfied.SELECTED DRAWING: Figure 4
【課題】小型化を可能にしながら排水能力を向上できる、排水部材及び排水システムを提供する。【解決手段】排水部材５は、竪管３及び横管４を有する排水システムの一部を構成する。排水部材５は、排水システムの上流側に向けられる第１開口５ａと、排水システムの下流側に向けられる第２開口５ｂと、第１開口５ａと第２開口５ｂの中心軸Ｃ１，Ｃ２同士が交差するように第１開口５ａと第２開口５ｂとをつなぐ屈曲流路５ｃと、を有する。屈曲流路５ｃの流路断面積が第２開口５ｂの断面積よりも小さくなる縮小部位５ｃ１が屈曲流路５ｃの内周側の角５ｄと第２開口５ｂとの間に存在するように、屈曲流路５ｃの内周側の第１壁面５０ｂが、屈曲流路５ｃの外周側の第２壁面５０ｃに向かって突出する。第２開口５ｂの直径をｄ、第２開口５ｂの中心軸Ｃ２の方向における縮小部位５ｃ１の長さをＬとすると、０．５ｄ≦Ｌ≦５．０ｄである。【選択図】図４
