FIG. 1 is an explanatory view of a drain socket showing an embodiment according to the present invention. Moreover, the enlarged view of the drain socket from which only the step part location of a drain socket differs in FIG.
The drain socket 30 has a drain 31 side opening provided with a connection portion 31 with the trap 26 of the toilet 27, a fixing portion 32 to the floor 41 of the drain socket 30 itself, and a drain tube side opening 33 that guides drainage to the drain pipe 42. 34. W is a wall of the toilet space where the toilet 27 is installed.
Next, the flow of cleaning water when cleaning the toilet bowl 27 will be described.
Wash water from a tank (not shown) for storing the wash water enters from the water supply port 21 and flows into the bowl surface 24 through the spray hole 23 vacated at the bottom of the rim portion 22 while passing through the rim portion 22. Thereafter, the water level in the bowl surface 24 rises and the drainage begins to fall from the drain port 25 of the trap 26, collides with the step 35 on the inner wall of the drain socket 30, and the drainage after the collision is a water film in the drain socket 30. Then, the siphon is activated, and the waste in the bowl surface 24 passes through the drain socket and enters the drain pipe.
[0013]
Next, the movement of the drainage when flowing into the drainage pipe will be described with reference to FIG.
The drain socket 51 shown in FIG. 2 is provided with a packing 62 at a connecting portion 61 with the trap 52 and a through hole 57 through which a screw 56 for fixing to the floor 54 is passed, and is fixed by the screw 56. . The drain pipe side opening 65 is characterized in that the inner wall of the drain pipe 66 opposite to the bending direction of the drain pipe 66 is longer than the bent side.
Therefore, in this embodiment, as shown by the arrows in the drawing, the drainage discharged from the drainage pipe side opening 64 is difficult to go in the direction of the gap 71, and the scattering of drainage at the collision of the drainage pipe 66 is reduced, and the movement of Therefore, it becomes easier to go to the downstream direction of the drain pipe 66, which is the traveling direction, by reducing the resistance. Therefore, the possibility of stagnation of the drainage in the drain pipe 66 is reduced, which leads to further water saving.
1 and FIG. 2 differ only in the location on the inner walls of the step portions 35 and 63, and the same action is applied to the behavior of drainage at the time of a drain pipe collision.
Moreover, what is necessary is just to select the most suitable position, shape, etc. of a step part according to the inflow situation to the trap of drainage according to the kind of toilet bowl.

It is characterized by the point formed from The drain socket body 81a has a through hole 84 on a surface substantially parallel to the floor 82, and is fixed to the floor 82 through a screw 83 in the through hole. Further, a traveling direction adjusting portion 89 that is an inclined portion having an arbitrary angle is integrally formed at an arbitrary portion of the drain pipe side opening 90.
Therefore, most of the drainage that has come out from the drain outlet of the trap collides with the traveling direction adjusting portion 89 of the drainage pipe side opening 88 and proceeds in the downstream direction of the drainage pipe 91 as indicated by an arrow in the figure. . That is, by colliding with the traveling direction adjusting portion having an arbitrary angle before colliding with the drain pipe 91, it becomes easier to proceed in the downstream direction of the drain pipe than when colliding with the bottom of the substantially horizontal drain pipe. In addition, it is difficult to reach the gap 92 opposite to the traveling direction.
In addition, since the drain pipe side opening has a detachable part, the drain pipe side opening can be provided in a suitable state.
Therefore, in the present invention, the scattered state of the waste water at the time of the collision of the drain pipe 91 is reduced, and the resistance for movement is reduced, so that it becomes easier to go downstream of the drain pipe, which is the traveling direction. Therefore, the possibility of stagnation of drainage or the like in the drain pipe 91 is reduced, which leads to further water saving.
In addition, since the relationship between the position of the fixing portion 85 and the bent portion of the drain pipe 91 varies from site to site, the drain pipe side opening 88 can be attached and detached, so that the drain pipe side opening according to the bending direction of each site. By connecting 88, it becomes possible to install the traveling direction adjusting unit at an optimum position at each site.

FIG. 4 shows an outline of the connection structure between the lower part of the drain socket and the drain pipe.
The drain socket 101 has an inclined portion having an arbitrary angle as a drainage traveling direction adjusting unit 104 at a portion where the drainage falls from the toilet trap, and the drainage pipe 113 is a downstream direction of the drainage pipe 113. A drain pipe side opening 103 opens toward the end. A gap closing member 105 made of rubber or the like that fills the gap 111 between the drain pipe 113 and the drain socket is provided on the opposite side of the drain pipe side opening 103, and is in contact with the drain pipe 113 and the drain socket 101.
Therefore, as shown by the arrow in the figure, the waste water falling from the upstream collides with the traveling direction adjusting portion 104 below the drain socket 101 and flows out from the drain pipe side opening 103 toward the downstream side of the drain pipe 113. . Therefore, there is no drainage that scatters into the gap 111 compared to when falling from the conventional drainage pipe side opening indicated by a two-dot chain line in the figure, and the opening is installed in the downstream direction of the drainage pipe. Smooth drainage flow in the drain pipe can be realized. Further, since the gap closing member closes the gap between the drain pipe 113 and the drain socket 101, the intrusion of the drainage into the gap 111 of the drainage after flowing into the drain pipe 113 can be more reliably prevented. The shape and the mounting position of the gap closing member are not limited to those of the present embodiment, and may be installed at a position that does not enter the gap portion other than the traveling direction of the drain pipe and the drain socket.
