CIRCULATING TOILET

PROBLEM TO BE SOLVED: To improve washing ability while preventing flushing water from continuing to flow even after the stop of a pump by a siphon phenomenon. SOLUTION: A circulating line is formed among a flush tank 12, a toilet bowl 2 and a sewage treating tank 30, and flushing water 31 is supplied to the toilet bowl 2 through piping 6 from a submerged pump 5 disposed in the flush tank 12. The toilet bowl 2 is disposed in a lower position than the water level of the flush tank 12. The piping 6 has: a lifting pipe 60 pumping up the flushing water 31 in the flush tank 12 by the submerged pump 5; a regulating pipe 61 connected to the lifting pipe 60 and disposed in a higher position than the water level of the flush tank 12; and a bent pipe 62 supplying the flushing water 31 from the regulating pipe 61 to the toilet bowl 2 via a lower position than the toilet bowl 2. An air intake valve 15 is provided for taking the atmosphere at negative pressure into the regulating pipe 61. COPYRIGHT: (C)2008,JPO&INPIT
