TOILET SYSTEM

PROBLEM TO BE SOLVED: To provide a toilet system which improves dirt conveyance capacity in pipelines by utilization of conveyance water even in a building which cannot secure a space for providing a storage tank, and which can greatly reduce the amount of toilet bowl washing water by circulation use of the conveyance water.SOLUTION: A toilet system 10 includes: toilet bowls 11; and a horizontal drain pipe 13 which is arranged to be inclined downward as it goes to the downstream side from the upstream side, and in which discharge discharged from the toilet bowls 11 and the conveyance water for conveying the discharge circulate by a toilet bowl drain pipe 12 of the toilet bowls 11 being connected. The horizontal drain pipe 13 is constituted by including a storage part 13C formed on the downstream side and for storing the conveyance water, and the toilet system also includes a supply part 20 for supplying the conveyance water in the storage part 13C to an upstream part of the horizontal drain pipe.SELECTED DRAWING: Figure 1 【課題】貯留槽を設けるスペースを確保することができない建物においても、搬送水の利用により配管中の汚物搬送能力を向上させ、かつ搬送水の循環利用により、便器洗浄水量の大幅な削減が可能なトイレシステムを提供すること。【解決手段】便器１１と、上流側から下流側に向かうに従い下方に傾斜して配置され、便器１１の便器排水管１２が接続されることで、便器１１から排出された排出物及び該排出物を搬送する搬送水が流通する排水横管１３と、を備えるトイレシステムであって、排水横管１３は、その下流側に形成され前記搬送水を貯留する貯留部１３Ｃを含んで構成され、貯留部１３Ｃ内の搬送水を前記排水横管の上流部に供給する供給部２０を更に備えるトイレシステム１０を提供する。【選択図】図１
