NEGATIVE PRESSURE SUCTION-TYPE TOILET
PROBLEM TO BE SOLVED: To facilitate negative pressure of a negative pressure tank to work effectively on drain pooled in a toilet bowl.SOLUTION: A negative pressure suction-type toilet 10 of the present invention includes a toilet bowl 11 having a drain port 11a at a bottom part, a negative pressure tank 12 having a suction port 12a, drainage pipeline 13 connected to the drain port and the suction port and laid from the drain port to the suction port, and a vacuum pump 14 connected to the negative pressure tank. The drainage pipeline includes a rising part 13a provided on an end of the drainage pipeline connected to the drain port and extending upward to a prescribed height of the toilet bowl from the drain port, rising pipe parts 13b, 13c provided on a downstream side of the rising part in a drainage flow direction from the toilet bowl to the negative pressure tank, and receiving parts 13b1, 13c1 disposed on an immediate upstream side of the rising pipe part and having a volumetric capacity larger than the rising pipe part.SELECTED DRAWING: Figure 2
【課題】負圧タンクの負圧は、便器に溜まった排水に作用しやすくなる。【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を有する負圧タンク１２と、排水口と吸引口とに接続され、排水口から吸引口に至る排水管路１３と、負圧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、排水口に接続された排水管路の一方の端部に設けられ、かつ、排水口から便器の予め定められた高さまで上方に延びた立ち上がり部１３ａと、便器から負圧タンクに至る排水の流れ方向において、立ち上がり部よりも下流側に設けられた上り管部１３ｂ，１３ｃと、上り管部の直ぐ上流側に配置され、上り管部よりも大きい容積を有する受け部１３ｂ１，１３ｃ１とを有している。【選択図】図２
