OVERFLOW TYPE DISCHARGE DEVICE
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, an inflow unit 3 that is connected to a conical circumferential plate 21 of the overflow chamber 20 and causes water W to flow into the overflow chamber 20. and an outflow unit 4 that is connected to a small diameter edge 23 of the overflow chamber 20 and causes water W to flow out from the overflow chamber 20, and the overflow chamber 20 is installed so as to take an inverted position. And, in a front view seen from a direction perpendicular to a vertical direction Z and to the central axis 2C of the overflow chamber 20 (a front view seen from the front side F), the inflow unit 3 is arranged on a lower side D than the central axis 2C, and has an inflow hole 30 where an opening width Wa in a parallel direction Da is equal to or more than an opening width Wb in the vertical direction Db relative to 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を流入させる流入部３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を流出させる流出部４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、上下方向Ｚ及び過流室２０の中心軸２Ｃに対して垂直となる方向から視た正面視（前方側Ｆから視た正面視）にて、流入部３は、中心軸２Ｃよりも下方側Ｄに配置され、かつ中心軸２Ｃに対して平行方向Ｄａの開口幅Ｗａが垂直方向Ｄｂの開口幅Ｗｂ以上である流入孔３０を有する。【選択図】図１２
