DRAIN PIPE
PROBLEM TO BE SOLVED: To provide a drain pipe capable of preventing the inside of a drain flow passage from becoming a full water state, and to provide the drain pipe capable of securing a suitable drain flow rate by preventing a turbulent flow.SOLUTION: A drain pipe 1 comprises an inflow part 15 and a vertical pipe part 16. The inflow part 15 is also constituted of a straight line part 151 and a flat part 152. The flat part 152 is a fan shape in a side view, and an upstream side end part becomes a circular shape in a cross-sectional view, and a drain flow passage gradually extends upward and downward for advancing to the downstream side, and is deformed thereby in a flat shape from a cylindrical shape, and continues with the vertical pipe part 16. While, the flat part 151 is formed short up to an about half degree in a flow passage width in the horizontal direction by approaching one side surface of the drain flow passage to the other side surface. The flat part 152 also continues in the tangential direction with the vertical pipe part 16 in a plan view.
【課題】排水流路内が満水状態となることを防ぐ排水配管の提供、及び、乱流を防ぎ、好適な排水流量を確保することが可能な排水配管の提供を課題とする。【解決手段】排水配管１は流入部１５、縦管部１６を有している。又、流入部１５は直線部１５１と扁平部１５２より構成されている。扁平部１５２は側面視扇状であって、上流側端部が断面視円形形状となっており、下流側へ進むにつれて漸次排水流路が上方及び下方に延びることで円筒状より扁平状へと変形し、縦管部１６と連続する。一方、扁平部１５１は排水流路の一方の側面が他方の側面へと近づくようにして水平方向の流路幅が約半分程度まで短く形成されている。又、平面視において、扁平部１５２は縦管部１６に対して接線方向において連続している。【選択図】図４
