WATER STORAGE DEVICE

To provide a water storage device that can reliably agitate water in a water storage tank with tap water flowing in from a water pipe even if the water storage tank is large.SOLUTION: There is provided a water storage device 100, in which a water supply pipe nipple 32 connected to a water pipe WP is arranged on a water-supply-side wall surface 30 of a water storage tank 10 on the side to which the water pipe WP is connected, a water feed pipe nipple 42 connected to a water feed pipe DP is arranged on a water-feed-side wall surface 40 facing the water-supply-side wall surface 30 of the water storage tank 10 so as to keep the water storage tank 10 full at all times, the water supply pipe nipple 32 has a discharge port 34C protruding into the water storage tank 10 through the water-supply-side wall surface 30 and directed toward the inner peripheral surface of the water storage tank 10, and a spiral guide body 50 extending from the water-supply-side wall surface 30 to the water-feed-side wall surface 40 is attached to the inner peripheral surface.SELECTED DRAWING: Figure 1 【課題】大型の貯水タンクであっても、水道管から流入させた水道水により貯水タンク内の水を確実に撹拌させることが可能な貯水装置を提供する。【解決手段】貯水タンク１０において水道管ＷＰが連結される側の給水側壁面３０に水道管ＷＰと連結される給水管ニップル３２が配設され、貯水タンク１０の給水側壁面３０に対向する送水側壁面４０に送水管ＤＰと連結される送水管ニップル４２が配設され、貯水タンク１０を常時満水状態に保持し、給水管ニップル３２は、給水側壁面３０を貫通して貯水タンク１０内に突出した吐出口３４Ｃを貯水タンク１０の内周面に向けられていると共に、内周面には給水側壁面３０から送水側壁面４０に延びる螺旋状のガイド体５０が取り付けられていることを特徴とする貯水装置１００である。【選択図】図１
