DRAIN SOCKET, AND FLUSH TOILET BOWL PROVIDED WITH THE SAME
PROBLEM TO BE SOLVED: To provide a drain socket that suppresses siphoning in an underfloor drain pipe.SOLUTION: The present invention relates to a drain socket connecting a water outlet of a toilet bowl body with a drain pipe. The drain socket of the present invention includes: a vertical pipeline part connected to the water outlet of the toilet bowl body, for having sewage flow downward; and a bent pipeline part having a water inlet connected to the vertical pipeline part, the water outlet connected to an inlet part of the drain pipe, a flow channel through which sewage flows from the water inlet to the water outlet, and a bent part where the flow channel bends toward the water outlet from a side of the vertical pipeline part. A protrusion is provided on the bent part of the bent pipeline part, the protrusion having a protruded space formed that protrudes outward from the flow channel extending from an edge part of the water outlet on a side with the vertical pipeline part toward a side other than the side with the vertical pipeline part. The protrusion is formed such that a flow direction of sewage that flows into the inlet part of the drain pipe from the water outlet of the bent pipeline part is changed in a direction toward a center of the drain pipe, by the sewage that has flown into the protruded space from the flow channel.SELECTED DRAWING: Figure 1
【課題】床下排水管でのサイホンの発生を抑制する、排水ソケット等を提供する。【解決手段】本発明は、便器本体の流出口と排水管を接続する排水ソケットである。本発明の排水ソケットは、便器本体の流出口に接続され排水を流下させる鉛直管路部と、この鉛直管路部に接続される流入口と、排水管の入口部に接続された流出口と、この流入口から流出口へ排水が流れる流路と、鉛直管路部の側から流出口に向かって流路が屈曲する屈曲部と、を備えた屈曲管路部と、を有する。屈曲管路部の屈曲部には、流出口の鉛直管路部の側の端部から鉛直管路部の側以外の側に延びる流路から外方に向けて突出する突出空間が形成された突出部が設けられ、この突出部が、流路から突出空間に流入した排水により、屈曲管路部の流出口から排水管の入口部に流入する排水の流れの方向が排水管の中央方向に変化するように形成されている。【選択図】図１
