That is, once to cause siphon in the full level of the water flow path, it is necessary to narrow the flowing water channel, it becomes easy dirt clogging the narrow in the back-and-forth direction shifted backwards, increasing the amount diaphragm on the left right direction Thus, the clogging performance is not deteriorated.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a longitudinal cross-sectional configuration diagram of the toilet main body installed. The toilet main body 1 has a trap channel 1b formed in a substantially inverted U shape on the downstream side of the ball portion 1a, and the entrance of the trap channel 1b. 1ba is a linear inflow portion inclined downward from the ball portion 1a. Also, the ball portion 1a has a substantially straight shape from the front to the inlet 1ba of the trap channel 1b, so that the washing water can be effectively guided to the trap channel 1b, and the flow rate is secured. This makes it easier to discharge filth and requires less washing water. In addition, it is desirable to ensure 20 mm or more of the linear inflow part of the inlet 1ba of the trap flow path 1b.
In addition, a discharge port 1c opened toward the floor surface F is formed in a drooping shape at the downstream end of the trap channel 1b.
A drain socket 2 is provided to connect the discharge port 1c and the building-side drain pipe 7 embedded in the floor F. The drain socket 2 is shown in a half sectional perspective view in FIG. , A drooping pipe 4, an adjuster pipe 5 that extends substantially horizontally at the lower end of the drooping pipe 4, and a connecting pipe 6 that is connected to the tip of the adjuster pipe 5 in an inserted manner. A flow channel R through which drainage passes is formed.

  By using such a drain socket 2, the adjuster pipe 5 is cut to an appropriate size, so that the toilet body 1 is placed in an appropriate position in the toilet room so as to correspond to the drain core L1 between the wall surface W of the toilet and the center line of the drain pipe 7. FIG. 1 shows an installation state in which the toilet pipe body 1 is installed with the largest drainage core L1 by connecting the connecting pipe 6 without cutting the adjuster pipe 5. FIG. These show the case where the toilet main body 1 is installed with the minimum drainage core L2 by cutting the adjuster pipe 5 to the shortest dimension that can be accommodated.

In the drain socket 2 of this example, a bent portion B in which the water flow path R is eccentric to the rear (wall surface W) side is formed in the portion of the drooping pipe 4, and the bent portion B is eccentric. The minimum drainage wick L2 is shorter than before, and the length between the maximum drainage wick L1 and the minimum drainage wick L2 is larger than before. , You can afford.
Further, in the bent portion B, the resistance of running water is increased, and accordingly, siphon can be raised quickly, and the waste can be discharged well with a small amount of washing water.

As shown in the exploded view of FIG. 4, the drooping tube 4 in which the bent portion B is formed is divided into an upper member 41 and a lower member 42 so that the upper member 41 is inserted into the lower member 42. The adjuster pipe 5 is integrally formed continuously with the lower end of the lower member 42.

As shown in the enlarged longitudinal sectional view of FIG. 5, the deviation between the center line P1 of the upper end of the upper member 41 constituting the drooping pipe 4 and the center line P2 of the upper end of the lower member 42 having the rounded portion 42c constituting the drooping pipe 4 is shown. The core distance a is set to 20 mm, and the lower member 42 is offset by 20 mm toward the rear wall W side with respect to the upper member 41, and the upper member 41 is continuously bent from the lower member 42 to this eccentric portion. The bent portion B is formed in a curved shape, and the lower end side of the bent portion B is formed in a loose rounded portion 42c continuous to the adjuster pipe 5. The rounded portion 42c improves the flow of the waste, and the dirty pipe is adjusted. It is configured to be able to discharge well to the 5 side.

As shown in the enlarged half cross-sectional perspective view of FIG. 6, the upper member 41 of the drooping tube 4 is formed in a cylindrical shape with a rising portion 41a having a bamboo sword-like claw portion on the outside rising upward. The rubber packing 3 is put on the outer periphery and the upper surface of the rising portion 41a, and the outlet 1c of the toilet body is inserted into and connected to the upper surface insertion port 3a on the upper surface of the rubber packing 3.
The rubber packing 3 is difficult to come off by being locked to the claw portion of the rising portion 41a, and further, a fastening band (not shown) is fastened to the concave portion 3b below the rubber packing 3, so that the rubber packing 3 is It is firmly fixed to the rising portion 41a.
A horizontal portion 41b extending substantially horizontally inward is formed at the lower end of the rising portion 41a. A vertical portion 41c is formed by hanging from the inner end side of the horizontal portion 41b, and further on the lower end of the vertical portion 41c. A shelf portion 41d is formed extending substantially horizontally to the inside, and the inner periphery of the shelf portion 41d is an inlet 41e having an inner diameter of 58 mm and a circular cross section.
A bent portion B is continuously formed curved downward from the shelf portion 41d and an insertion portion 41f is integrally formed on the outer periphery of the lower end of the upper member 41 in a thick shape.

On the other hand, an upper end of the lower member 42 of the drooping tube 4 is formed with a joint receiving portion 42a having an open upper surface, and the lower surface of the joint receiving portion 42a is a stepped contact step portion 42b extending inward. The insertion portion 41f is fitted into the joint receiving portion 42a until the lower end of the insertion portion 41f of the upper member 41 contacts the contact step portion 42b, and the insertion portion 41f and the joint receiving portion 42a are inserted. Is assembled in one piece at the factory via an adhesive. Thereby, the connection part in a construction site reduces and a water leak risk can be reduced.

FIG. 7 shows a perspective view cut horizontally at the contact step 42b. In the vicinity of the contact step 42b, the cross-sectional shape of the flowing water channel R is substantially D-shaped, and the dimension b in the front-rear direction is The dimension c in the left-right direction is set to 53 mm. In other words, the cross-sectional shape of the flowing water channel R in the vicinity of the contact step portion 42b in the bent portion B has a throttle amount in the left-right direction larger than the throttle amount in the front-back direction.
In order to make the siphon easy to raise well, it is necessary to squeeze the flowing water channel R. However, if the anteroposterior direction (the direction in which the flowing water flows) is narrowed, dirt is likely to be clogged. The siphon performance can be improved without increasing the amount and reducing the clogging performance. Therefore, the waste can be discharged with a small amount of washing water.

A fixing flange portion 42d is integrally formed on the outside of the lower member 42 of the drooping tube 4. A screw is inserted into the screw hole 42e of the fixing flange portion 42d, and the floor surface F is drained with a screw. 2 can be fixed.
The adjuster pipe 5 extends horizontally from the lower member 42, and the upper surface of the adjuster pipe 5 is formed in a substantially horizontal plane 5a. The flow channel inside the adjuster pipe 5 has a cross section with a minimum diameter of 56 mm. It is formed in a D shape. Further, the adjuster pipe 5 is manufactured by pulling out the mold to the right side at the time of manufacture, and a gradient is formed toward the connecting pipe 6 with a forward gradient of 1/200 by the punching mold. As a result, no washing water remains in the adjuster pipe 5 and it is possible to prevent dew condensation from occurring in the adjuster pipe 5.
In addition, since the drooping tube 4 can be divided into the upper member 41 and the lower member 42 and formed, the mold can be satisfactorily extracted during manufacture, and the manufacture becomes easy.

Note that the shelf 41d formed on the upper member 41 of the drooping pipe 4 temporarily applies the washing water from the outlet 1c of the toilet body 1 to the shelf 41d and runs the washing water along the inner peripheral wall. The function is that it can be collected in the vicinity of the center of the path R, and the washing water from the discharge port 1c is collected in the central direction via the shelf 41d so that the siphon force can be increased.
The connecting pipe 6 is integrally formed with a swollen cylindrical portion 6a whose diameter is increased at the tip, and a fixing flange portion 6b fixed to the floor surface F is integrally formed at the lower end on the opposite side. The tip of the adjuster tube 5 is inserted into the swallowed cylinder portion 6a.
In this example, the lower member 42 and the adjuster pipe 5 constituting the drooping pipe 4 are illustrated as being continuously integrated. However, the lower member 42 and the adjuster pipe 5 are divided into two so as to be connectable. It may be.
