  In the toilet drainage structure described above, the lower part of the discharge chamber in which the bent tube is housed in the flush toilet is used as the drainage discharge part. Therefore, the toilet drainage structure can only be applied to flush toilets with floor drainage specifications. . Since toilets installed on the upper floors of the second floor and above may have wall drainage flush toilets that discharge in the direction of the wall, this can also be applied to such wall drainage flush toilets. In addition, a drainage structure for a hand-washing machine, which has a common specification with a flush toilet with a floor drainage specification, is definitely desired. In addition, in order to realize such a drainage structure for a hand-washing machine, if the flush toilet is wall drainage type, the washing water is discharged from the discharge chamber in the wall direction, and the washing water enters the drainage pipe of the hand-washing machine. Consideration to prevent inflow is required.

  The present invention has been made in view of the circumstances as described above, and can be realized as a common specification for flush toilets of floor drainage specifications and wall drainage specifications, is highly versatile, and the flushing water of flush toilets is hand-washed. It is an object of the present invention to provide a drainage structure for a hand-washing machine that can prevent the water from flowing into the drainage pipe of the bowl.

  In order to solve the above problems, the present invention enables a bent tube that can be turned in the vertical direction to form a puddle in the bowl by directing the open end upward, and the open end can be formed by turning the bent tube. From a hand-washing device arranged separately from the flush toilet at the upper end of the discharge chamber in which the bent tube in the flush toilet that can collect the filth in the bowl and drain it together with the wash water when it is turned downward The drainage pipe wall is connected to the drain end of the drainage pipe, and the flushing water prevention wall that prevents the flushing water flowing into the drainage chamber from flowing into the drainage chamber when washing the flush toilet It is characterized by being arranged opposite to.

  According to the present invention, since the drain pipe from the hand-washing device disposed separately from the flush toilet is connected to the upper end of the discharge chamber in which the bent tube is stored in the flush toilet, the discharge provided in the discharge chamber The part can be arranged not only in the lower part of the discharge chamber, but also on the rear side of the flush toilet. Therefore, regardless of the floor drainage specification or the wall drainage specification, the drainage pipe of the handwasher can be connected to the discharge chamber of the flush toilet, and the wastewater of the handwasher can be discharged from the discharge chamber of the flush toilet. The drainage structure of the handwasher of the common specification is realized for the flush toilet of the floor drainage specification and the wall drainage specification, and is highly versatile.

  In addition, since the washing water prevention wall is disposed inside the discharge chamber so as to face the connection end of the drain pipe of the hand-washing machine, even if the drain pipe of the hand-washing machine is connected to the upper end of the discharge chamber. The washing water flowing into the discharge chamber during washing of the flush toilet can be prevented from flowing into the drain pipe of the hand washing machine.

One end of the bending tube 5 communicates with the bowl 4 and the other end is an open end 6. As shown in FIG. 2, when the open end 6 faces upward, tap water is supplied into the bowl 4, and a pool of water up to the open end 6 of the bent tube 5 is formed in the bowl 4. Is done. When the bent tube 5 rotates and the open end 6 faces downward, the cleaning water is supplied into the bowl 4 and the filth in the bowl 4 is discharged together with the reservoir water and the cleaning water. The vertical rotation of the bending tube 5 is realized by the support portion 7 that supports the open end 6 being supported by a rotation shaft that extends in the horizontal direction, and the driving force from the motor is transmitted to the support portion 7. Accordingly, the bent tube 5 automatically rotates in the vertical direction by the input of the electric signal, and the flush toilet 1 discharges the filth and cleans the bowl 4, and uses the water used for discharging the filth and cleaning the bowl 4. However, it has excellent discharge performance and cleaning performance even in a small amount as compared with siphon jet flush toilets, and has a feature that it is a water-saving flush toilet and has a quiet washing sound.

  The bent tube 5 is housed in a case-like discharge chamber 8 provided in the flush toilet 1 and communicated with the bowl 4, and can be rotated in the vertical direction inside the discharge chamber 8. The discharge chamber 8 has an opening at the lower rear portion, and one end of a tubular discharge portion 9 is connected to the discharge chamber 8 via an annular flange 10 provided on the outer periphery thereof. The discharge portion 9 is located inside the discharge chamber 8. Communicating with As shown in FIG. 1, the other end of the discharge portion 9 extends in the wall direction like the water supply pipe 3 and is connected to a drain pipe drawn in toward the wall. The filth, pool water, and washing water that flow into the discharge chamber 8 when the bowl 4 is washed are directed to the discharge portion 9 through the opening of the discharge chamber 8 and discharged to the drain pipe. That is, the flush toilet 1 shown in FIGS. 1 and 2 has a wall drain specification.

  The hand-washing machine 11 is separate from the flush toilet 1 as described above, and is attached to a wall surface different from the wall on the connection side of the water supply pipe 3 and the discharge part 9 of the toilet 2. The hand-washing machine 11 includes a currant 12 and a hand-washing bowl 13, and the currant 12 is provided with a rotary operation unit 14. A drain port 15 provided at the bottom of the hand-washing bowl 13 communicates with a drain pipe 16 extending downward from the hand-washing machine 11, and the drain pipe 16 also extends toward the flush toilet 1 as shown in FIG. The drainage pipe connecting portion 17 provided at the upper end of the discharge chamber 8 provided in the flush toilet 1 is connected to the discharge chamber 8 via the drainage pipe connecting portion 17.
