DRINKING WATER SUPPLY DEVICE
PROBLEM TO BE SOLVED: To provide a drinking water supply device that prevents stay of tap water, has sanitation resistance, and eliminates the necessity for a pressure-reducing valve by using a synthetic resin hose having a larger diameter than that of a water pipe in a residence and having flexibility and softness between a water supply pipe and a faucet.SOLUTION: A drinking water supply device comprises at least a check valve connected to a water supply pipe in a residence, a synthetic resin hose connected to the outlet side of the check valve and having flexibility and softness, a water cutoff valve connected to the outlet side of the synthetic resin hose, a T-shaped pipe connecting a projecting discharge pipe in the synthetic resin hose in the vicinity of the check valve, and a discharge valve connected to the discharge pipe of the T-shaped pipe. A nominal diameter of the synthetic resin hose is 20-40 mm. The synthetic resin hose is spirally wound in a bundle of a plurality of stages and a plurality of rows.SELECTED DRAWING: Figure 1
【課題】本発明は、住居内の水道管の径より太径で、可とう性、柔軟性を有する合成樹脂性ホースを給水配管と蛇口の間に用いることによって、水道水の滞留を防止すると共に耐衛生性があり、さらに、減圧弁が不要となる飲料水供給装置を提供する。【解決手段】住居内の給水配管に連結する逆止弁と、該逆止弁の出口側に連結された可とう性および柔軟性を有する合成樹脂製ホースと、該合成樹脂性ホースの出口側に連結された止水バルブと、前記逆止弁の近傍の前記合成樹脂製ホースに吐出管を突設させたＴ字管と、該Ｔ字管の該吐出管に連結された吐出バルブと、を少なくとも備えた飲料水供給装置であって、前記合成樹脂ホースの呼び径が２０〜４０ｍｍであり、該合成樹脂ホースを螺旋状に巻きつけて、複数段、複数列の巻き束にしたことを特徴とする。【選択図】図１
