Abstract: PURPOSE: An effective odor isolation method and a manufacturing method for a rainwater utilization system are provided to cut off the offensive odor exhausted to a drainpipe effectively and to remove impurities in a drainpipe easily. CONSTITUTION: The effective odor isolation method and the manufacturing method for a rainwater utilization system comprise the steps of putting an odor isolator connected with a feed hole of a feed pipe fixed with an O-ring and a drainage hole of a drainpipe to a drainpipe formed on the side of a drainage tub, placing an odor isolator stopper coupled with a male screw on a female screw of a cover composed of many spaces and many arms on a ring-shaped projection provided with a gutter and a vertical drain-outlet, placing an odor isolator stopper provided with an isolating stopper and a drainpipe on a ring-shaped projection provided with a gutter and a vertical drainpipe on the internal wall of a pipe fixed with an O-ring, fixing a net(46) provided with many perforation holes(45) on the odor isolating stopper and the drainpipe, connecting a drainpipe(49) provided with a drainpipe(47) and a ring-shaped projection(48) on the lower end of a drainpipe(44), then connecting a drainpipe(50) to the lower end, placing a valve(53) provided with a packing(51) and a bearing(52) on a ring-shaped projection(48) of a drainpipe(49), connecting a push stick(55) installed to a bearing(52) by a shaft(54) with a lever(56) installed to a bearing(57) of a branch pipe(47) by a shaft(58) using a shaft(59), coupling a handle(60) to the projected shaft(58), connecting a drainpipe(63) to a branch pipe(47) and connecting an L-shaped feed pipe(65) provided with an overflow pipe(64), controlling the length of a string(62) to close a ball valve(67) when a valve(53) is opened by a water tank(61) by binding up a handle(96) with a strip(62) connected to a handle(60), connecting the bottom of a water tank(61) and a handle(68) with a string(95), connecting a horizontal feed pipe(66) to a feed pipe(71) of the bottom of a water tank fixed with a corrugated water tank(70) of a float(69), connecting a feed pipe(74) of a water gauge(73) to a drainpipe(72) of the bottom of a water tank and fixing a ball valve(75) to the feed pipe(74), fixing a suction valve(83) provided with a packing(81) and a ball(82) on a right-shaped projection(80) of an external wall, fixing a backflow preventive valve(86) provided with a packing(88) and a ball(89) to an upper hole(85) of a wall between a water tank(77) and a compression room, fixing a ball valve(92) to the lower end of an exhaust pipe(90) connected with a compression room and a water gauge(73), connecting a hose(94) to a lower hole(93) of a water gauge(73), fixing a valve(103) provided with a packing(101) and a grip(102) to the inner side of a ring-shaped projection(100) of a ball valve(97) and a valve housing(99) connected to a hole(93), then coupling a bolt pipe(104), and fixing a float(106) to the end of the grip(102).
