NEGATIVE PRESSURE SUCTION TYPE TOILET
PROBLEM TO BE SOLVED: To smoothly discharge wastewater to sewerage from a negative pressure tank.SOLUTION: A negative pressure suction type toilet 10 includes: a toilet bowl 11, the bottom of which has a drain outlet 11a; a tank 12 having a suction port 12a; a drainage duct 13 that forms a channel leading from the drain outlet to the suction port; and a vacuum pump 14 that is connected to the tank. In the drainage duct, bent sections 13b, which are formed by bending the duct, respectively, are provided within a range up to 3 m along the duct axis from the suction port.SELECTED DRAWING: Figure 2
【課題】負圧タンクから下水設備に排水をスムーズに排出すること【解決手段】ここで提案される負圧吸引式トイレ１０は、底部に排水口１１ａを有する便器１１と、吸引口１２ａを有するタンク１２と、排水口から吸引口に至る流路を形成する排水管路１３と、タンクに接続された真空ポンプ１４とを備えている。排水管路は、吸引口から管軸に沿って３ｍまでの範囲内に、それぞれ管路が曲った折曲区間１３ｄを備えている。【選択図】図２
