EXCREMENT SINK FOR OSTOMATE
PROBLEM TO BE SOLVED: To provide an excrement sink for ostomate which stabilizes a flow rate and a flow velocity of discharged washing water when a water supply pressure of the washing water supplied to a water supply connection port fluctuates and can suppress an occurrence of water splashing from the bowl part while reducing the size.SOLUTION: An excrement sink for ostomate arranged along a wall surface of a building includes: a bowl part in which an upper part is opened to throw in excrement, and a peripheral wall surface is formed in a substantially elliptical shape; a water accumulation part for accumulating seal water; a trap duct which is formed to ascend from a lower part of the water accumulation part and forms seal water in the water accumulation part; a water discharge port which is opened on the peripheral wall surface of the bowl part and discharges the washing water to rotate along the peripheral wall surface in a horizontal direction; and a water guide passage for communicating a water supply connection port connected to a water supply source with the water discharge port. The water guide passage has a constriction part in which a cross section of a flow passage is narrower than that of the flow passage of the water supply connection port and a bulging part in which a cross section of a flow passage is wider than those of the flow passages of the constriction part and the water discharge port in a downstream side of the constriction part.SELECTED DRAWING: Figure 4
【課題】小型化しながら、給水接続口へ供給される洗浄水の給水圧力が変動したとしても、吐水された洗浄水の流量や流速を安定させ、ボウル部からの水跳ね発生を抑制できるオストメイト用汚物流しを提供すること。【解決手段】建物の壁面に沿って配置されるオストメイト用汚物流しであって、汚物が投入可能となるように上方が開口され、周壁面が略楕円形状に形成されたボウル部と、封水が溜まる溜水部と、溜水部の下部から上昇するように形成され、溜水部に封水を形成するトラップ管路と、ボウル部の周壁面に開口し、周壁面に沿って水平方向に旋回するように洗浄水を吐水する吐水口と、給水源と接続された給水接続口と吐水口とを連通する導水路と、を備え、導水路は、給水接続口よりも流路断面積が狭い絞り部と、絞り部よりも下流側において、流路断面積が絞り部及び吐水口の流路断面積よりも広い膨張部と、を有することを特徴とする。【選択図】 図４
