Description

Here, in the flush toilet according to claim 1, a drain connecting pipe for connecting the discharge port of the flush toilet and the discharge port on the building side arranged at a floor surface position deviated from the discharge port is provided. It is disposed between the floor and the toilet bowl even Ru can.

Also, in washing off type flush toilet bowl described above, Ru can also connect the drain pipe of the drain connecting pipe to the toilet room other installation sanitation equipment. As sanitary equipment, hand wash basins, sewage distribution, and drain pipes such as wash basins can be connected.

A drainage connecting pipe for connecting the discharge port of the flush toilet according to claim 1 and the discharge port on the building side arranged at a floor surface position deviated from the discharge port is provided between the floor surface and the toilet bowl. If arranged, the drainage pipe of the toilet bowl is arranged in the space between the bottom of the ball portion of the toilet bowl and the floor surface.

If the drainage pipe of the sanitary equipment installed in the toilet room or the like is connected to the drainage connecting pipe, the drainage of the sanitary equipment is flowed to the drainage channel of the flush toilet.

FIG. 3 is a vertical cross-sectional view showing another embodiment of the wash-off type flush toilet according to claim 1. By making the basic flush toilet structure the same as that of the flush toilet shown in FIGS. 1 and 2, the water force from the large-diameter injection hole 1d is particularly weaker than that of the conventional flush toilet. In addition to being able to solve the problem of splashing the wash water, the flush toilet 1 has the same height, and the large-diameter injection hole 1d in the rim water passage 1b is connected to the bottom of the ball. The distance (height) can be reduced. This makes it possible to provide a space on the back side of the lower part of the ball portion for connecting the discharge port on the building side and the discharge port of the toilet bowl. The toilet side discharge port connecting pipe 9 is sealed and connected to the toilet bowl discharge port 3a by an elastic packing 12. The building side discharge port connecting pipe 10 is sealed and connected to the building side discharge port 14 by an elastic packing 13. The toilet bowl side discharge port connecting pipe 9 and the building side discharge port connecting pipe 10 are connected by a drainage connecting pipe 11 and welded. Since the distance between the discharge port 3a of the toilet bowl and the discharge port 14 on the building side differs depending on the building, the drainage connecting pipe 11 is cut and connected by adjusting the length.

Further, FIG. 4 is a vertical cross-sectional view showing another embodiment of the flush toilet according to claim 1 , and FIG. 5 is a perspective view of a toilet room using the flush toilet of FIG. In FIG. 5, a cabinet 18 that conceals a flush water tank (not shown) and the like is provided behind a flush toilet 1 provided in the toilet room, and a hand wash device 17 is installed on the side wall surface of the toilet room. Water can be supplied to the hand-washing device 17 by a water supply pipe 19 branched from the water supply system that supplies water to the washing water tank, and drainage from the hand-washing device 17 can be washed off by washing the hand-washing device drain pipe 15 provided with a trap portion 21 in the middle. As shown in FIG. 4, from the rear of the toilet bowl 1, a hand washer drainage pipe connection portion 16 is provided and connected to the toilet bowl side discharge port connection pipe 9. The connection destination is not particularly limited as long as it is on the downstream side of the sealing surface W of the drainage channel 3. In particular, in the flush toilet 1 having a flush water channel structure as shown in FIG. 4, the flow rate at the moment when the flush toilet is discharged from the discharge port 3a of the toilet is smaller than that of the siphon flush toilet, and the hand wash drain pipe 15 The inside is less likely to become negative pressure . Therefore, it becomes difficult to break the water seal of the trap portion 21 of the hand wash device drain pipe 15. In addition, by using the water supply and drainage pipe connection methods as shown in FIG. 5, the existing water supply and drainage facilities can be used without newly installing water supply and drainage facilities for hand washers in the toilet room. It is very effective for indoor renovation work. Further, the water supply pipe 19 and the hand wash device drain pipe 15 are concealed in the counter 20 extending from the hand wash device 17 to the cabinet 18 on the side of the toilet room, so that the aesthetic appearance is not spoiled.
