To provide an overflow type discharge device capable of realizing a desired discharge performance.SOLUTION: An overflow type discharge device 1 includes a main body 2 in which a truncated conical overflow chamber 20 is formed, two inflow units 3, 4 that are connected to a conical circumferential plate 21 of the overflow chamber 20 and causes water W to flow into the overflow chamber 20. and one outflow unit 5 that is connected to a small diameter edge 23 of the overflow chamber 20 and causes water W to outflow from the overflow chamber 20, and the overflow chamber 20 is installed so as to take an inverted position. And, a first inflow unit 3 has, in a front view seen from a front side F, an inflow hole 30 arranged on a lower side D than the central axis 2C, and a second inflow unit 4 has, in a back view seen from a back side B, an inflow hole 40 arranged on an upper side U than the central axis 2C.SELECTED DRAWING: Figure 12
【課題】所望の放流特性を実現できる過流式放流装置を提供する。【解決手段】過流式放流装置１は、円錐台形状の過流室２０が形成された本体部２と、過流室２０の円錐周板２１に連設されて過流室２０に水Ｗを流入させる二つの流入部３，４と、過流室２０の小径端縁２３に連設されて過流室２０から水Ｗを流出させる一つの流出部５とを有し、過流室２０が倒位姿勢となるように設置されている。そして、第一流入部３は、前方側Ｆから視た正面視にて、中心軸２Ｃよりも下方側Ｄに配置された流入孔３０を有し、第二流入部４は、後方側Ｂから視た背面視にて、中心軸２Ｃよりも上方側Ｕに配置された流入孔４０を有している。【選択図】図１２
