To provide the defecation assist pressure reduction type water washing toilet system that can solve a problem of wiping with a toilet paper, the problem that infectious pathogens are causing the spread, therefore, the problem of not being able to defecate smoothly for the elderly and injured, and the problem that wiping is difficult, in a conventional toilet system with hot water shower washing after defecation with insufficient washing ability and hot air drying that requires a long time.SOLUTION: The defecation assist pressure reduction type water washing toilet system enables elevation of defecation and defecation assistance by using hot water and negative pressure, allows for sufficient local cleaning with pulsed hot water cleaning equipment, allows for removal of mechanical water droplets in suction air that is sucked into a negative pressure through a buttock and a pubic area, and enables drying to be completed in a short time by creating a mechanism for drying in two stages. As a result, an operation of wiping with the toilet paper became unnecessary.SELECTED DRAWING: Figure 1【課題】従来のトイレシステムでは、排便後の温水シャワー洗浄は不十分な洗浄能力しかなく、温風乾燥は長時間を必要とするから、トイレットペーパーで拭いている。そのために感染性病原菌が蔓延拡大する原因になっている。また高齢者や傷害者にとって排便をスムーズに行えず、拭き取る作業も難儀である。【解決手段】温水や負圧を利用して便意を高揚して排便をアシストし、パルス温水洗浄装置で局部を充分洗浄し、お尻と陰部を通る負圧に吸い込まれる吸引気流で機械的に水滴を除去し、2段階で乾燥する仕組みを作って短時間で乾燥を完了できるようにした。その結果、トイレットペーパーで拭く作業が不要になった。【選択図】図１
