INNER-WALL-SURFACE RAIN WATER UTILIZING DEVICE WITH LEADER BY SPIRAL STRUCTURE FILTRATION SYSTEM AND WATER DISTRIBUTION SYSTEM FOR FLUSHING TOILET IN TIME OF DISASTER

摘要

PPROBLEM TO BE SOLVED: To provide a device/system, wherein an inner-wall-surface water at the time when rain water fell onto a roof through a leader is filtrated with a screen while the filtrate water is efficiently accumulated without going back again to the leader, so as to effectively utilize filtrate rain water for flushing toilet in disaster and watering/gardening in yard. PSOLUTION: The inner-wall-surface water at the time when rain water fell onto the roof going through the leader D is filtered with a stainless screen pipe A with 1 mm mesh having the same diameter as the leader D. A spiral-structured blade C is provided to the outer side of the mesh so as to avoid the filtrate water from going back again to the leader but to allow the filtrate water to fall it along. The filtrate water furthermore keeps sticking to the inner surface of the pipe provided outside by means of a centrifugal force when falling along the spiral structure C. The fallen filtrate water is accumulated into a receptacle shaped as a doughnut ring at the bottom, a part of which is provided with a lower opening for the filtrate water to flow down and be accumulated. The accumulated water tank for the filtrate water placed above the toilet/bath tub can distribute water to each system. PCOPYRIGHT: (C)2007,JPO&INPIT
