DRAIN SOCKET AND WATER CLOSET HAVING THE SAME
PROBLEM TO BE SOLVED: To provide a drain socket and a water closet having the same, capable of effectively restraining negative pressure of trying to pull in upstream side wash water to the downstream side, while maintaining discharge performance, by making dirt-mixed waste water flowing in the drain socket smoothly flow.SOLUTION: A drain socket of the present invention is a drain socket for connecting an outlet part of a drainage channel of a toilet bowl body of a water closet and an inlet part of an underfloor drain pipe provided on a floor of a lower area in the toilet bowl body, and comprises a toilet bowl body side connection pipe member and an underfloor side connection pipe member for connecting the outlet part of this toilet bowl body side connection pipe member, and the toilet bowl body side connection pipe member comprises a descent pipeline, a bent pipeline connected to this descent pipeline and a horizontal pipeline connected to this bent pipeline and extending in the horizontal direction, and a projection part having a flat surface for changing the flow direction of waste water of flowing down toward an inflow port of the horizontal pipeline along a front side inner surface of the descent pipeline, is formed on the inner peripheral side of the descent pipeline being the bending directional side of the bent pipeline.SELECTED DRAWING: Figure 12
【課題】排水ソケット内を流れる汚物混じりの排水がスムーズに流れ排出性能を維持しつつ、上流側の洗浄水を下流側に引き込もうとする負圧を効果的に抑制することができる排水ソケット、及び、それを備えた水洗大便器を提供する。【解決手段】本発明の排水ソケットは、水洗大便器の便器本体の排水路の出口部と便器本体内の下方領域の床に設けられた床下排水管の入口部とを連結する排水ソケットであって、便器本体側接続管部材と、この便器本体側接続管部材の出口部とを接続する床下側接続管部材と、を有し、便器本体側接続管部材は、下降管路と、この下降管路と接続する屈曲管路と、この屈曲管路と接続し水平方向に延びる水平管路を備え、屈曲管路の屈曲方向側である下降管路の内周側には、下降管路の前方側の内面に沿って水平管路の流入口に向け流下する排水の流れ方向を変換する平坦状の表面を有する突起部が形成されている。【選択図】図１２
