RAINWATER USE DEVICE OF THE WAY MOUNTED TO THE WALL

摘要

PURPOSE: A hang-on-the-wall unit using rainwater is provided to supply rainwater to each floor of a building without additional power source. CONSTITUTION: A hang-on-the-wall unit using rainwater comprises a rainwater tank(10), and a fixing member. The rainwater tank is vertically installed on the wall of a building and stores rainwater rolling down from the roof. The rainwater tank comprises a fist rainwater tank(20), a second rainwater tank(30), and a rainwater switch valve(40). The first rainwater tank stores relatively dirtier rainwater rolling down from the roof. The second rainwater tank is separated from the first rainwater tank and stores clearer rainwater. The rainwater switch valve is arranged on the entrance of the first rainwater tank.
