BATHTUB WATER DISCHARGE DEVICE
To provide a bathtub water discharge device capable of inhibiting residual water from being generated in a throttling flow path.SOLUTION: A drain valve operation device 1, a bathtub water discharge device that is provided at a bathtub and makes laterally wide water be discharged toward around a user's shoulder, comprises: an ascension pipe 26; a storage chamber 36; a water discharge port 4 in a laterally wide shape for laterally discharging wide water; a throttling flow path 38 that is provided between the storage chamber and the water discharge port and is formed so as to have flow passage cross-sectional area smaller than that of the storage chamber so that water flowing in from the storage chamber is accelerated; a groove part 40 that is formed on a bottom surface of the throttling flow path and extends to the upstream side more than the throttling flow path; and drawing-in force generation means for drawing in residual water in the groove part in the throttling flow path, along the groove part to the upstream side using drawing-in force to the upstream side stronger than surface tension of the residual water.SELECTED DRAWING: Figure 7
【課題】絞り流路内に残水が生じることを抑制することができる浴槽用吐水装置を提供する。【解決手段】本発明の排水弁操作装置１は、浴槽に設置され、左右方向に幅広の水を使用者の肩付近に向けて吐水させる浴槽用吐水装置であって、上昇管２６と、貯留室３６と、左右方向に幅広の水を吐水する幅広形状の吐水口４と、貯留室と吐水口との間に設けられ、貯留室から流入した水を加速させるように、貯留室の流路断面積より小さい流路断面積を有するように形成されている絞り流路３８と、絞り流路の底面に形成され且つ絞り流路よりも上流側まで延びる溝部４０と、絞り流路内において溝部に溜まった水を、これらの溜まった水の表面張力より強い上流側への引き込み力により、溝部に沿って上流側に引き込む引き込み力発生手段と、を備えている。【選択図】図７
