  • Water closet and flushing water feed device
    Patent number: 6502251
    Abstract: A flush toilet 1 has a toilet flushing tank device 7 for discharging flushing water to a toilet bowl 2. This tank device is built into a tank storage region 5 to the rear of the toilet bowl 2, and comprises a flushing water tank 8 and a jet pump 13 disposed submerged in this flushing water tank 8. Flushing water (operating water) is supplied to this jet pump 13 via a flush valve 11 and a pipe 12 downstream from this valve. The jet pump 13 comprises a spray nozzle 131 and a throat 132 opposite thereto. Because the jet pump 13 is connected directly to a pipe 14, all of the flushing water jetted from the jet pump 13 passes directly to the pipe 14, and is guided by this pipe 14 to a rim water channel 4b.
