<p>PROBLEM TO BE SOLVED: To provide a socket which is suitable for connecting a toilet bowl to a drain pipe with a small aperture, and a drain pipe. SOLUTION: In the socket which is provided with a toilet stool connection part in which a drain port of the toilet bowl is inserted to the upper part, a contour part with a fixing part to a floor, and a drain pipe connection part in which a drain pipe is connected at the lower end, an outer diameter of the drain pipe connection part is set to be nearly equal to an inner diameter of the toilet stool connection part. And moreover, or, the drain pipe with a nominal diameter of 50 mm can be connected to the drain pipe connection part. Thereby, the drain is carried while being almost in the same diameter as the trap of the toilet bowl, the drain port, and the drain pipe, the receiving resistance is small. And also, a filth carrying capacity inside a horizontal drain branch pipe is enhanced since the drain drops in the form of a water lump the height from the trap to a bent part in which the drain pipe is bent from the vertical direction to the horizontal direction, and as a result, the flow velocity is gained. The filth, too, can be flowed in the drain pipe with almost the same diameter as the drain port of the toilet bowl without the resistance since the filth is discharged through the drain port of the toilet bowl.</p> |
