排水管套及具有该排水管套的水洗大便器
摘要：
提供抑制地下排水管发生虹吸现象的排水管套等。本发明是连接便器本体流出口与排水管的排水管套。本发明的排水管套具有连接于便器本体流出口让排水流下的铅垂管路部和弯曲管路部。弯曲管路部具备连接于该铅垂管路部的流入口、连接于排水管入口部的流出口、排水从该流入口流向流出口的流路及流路从铅垂管路部一侧向流出口弯曲的弯曲部。弯曲管路部的弯曲部设有突出部，突出部形成有从流出口的铅垂管路部侧的端部延伸至铅垂管路部侧以外一侧的流路上向外面突出的突出空间，该突出部的形成特征为，使从弯曲管路部流出口流入排水管入口部的排水的水流方向因从流路流入突出空间的排水而改变为排水管的中央方向。
摘要（英）：

The present invention is a discharge socket connecting a toilet main body and a discharge pipe. The discharge socket has a vertical conduit portion; and a bent conduit portion including an inflow port connected to the vertical conduit portion; an outflow port, connected to an inlet port of the discharge pipe; and a flow path, the flow path having a bent portion. A projecting portion is disposed on the bent portion, the projecting portion forming a projecting space which projects outward from the flow path. The projecting portion is formed so that the flow direction of discharge water flowing from the bent conduit portion into the inlet portion of the discharge pipe is changed to the center direction of the discharge pipe by the discharge water returning to the projecting space after flowing from the flow path into the projecting space.
