DRAIN PIPE PASSAGE SOCKET, TOILET BOWL USING THE SAME, AND SOCKET PARTS

摘要

PROBLEM TO BE SOLVED: To provide a new drain pipe passage socket which improves a toilet stool washing capacity by being mounted to a toilet bowl. SOLUTION: The drain pipe passage socket 28 has a connecting pipe passage part 29, a bent dropping pipe passage part 30, and a descending pipe passage part 32 so as to make a drain specification of the toilet bowl 10 as a floor drain specification. The descending pipe passage part 32 has an upstream socket piece 40 and a downstream socket piece 50 above and below at a straight pipe passage part to an external drain pipe GH. A throttle hole 42 and the throttle hole 52 of the respective socket pieces are eccentrically positioned on the opposite side against the axial center 32a of the straight pipe passage part. By this, storage of washing water at the respective throttle holes and splash of the washing water at shelf parts around the throttle holes are generated, and a water column is formed in the pipe passage.
