Abstract

The present invention is a discharge socket connecting a toilet main body and a discharge pipe. The discharge socket has a vertical conduit portion; and a bent conduit portion including an inflow port connected to the vertical conduit portion; an outflow port, connected to an inlet port of the discharge pipe; and a flow path, the flow path having a bent portion. A projecting portion is disposed on the bent portion, the projecting portion forming a projecting space which projects outward from the flow path. The projecting portion is formed so that the flow direction of discharge water flowing from the bent conduit portion into the inlet portion of the discharge pipe is changed to the center direction of the discharge pipe by the discharge water returning to the projecting space after flowing from the flow path into the projecting space.

First claim

What is claimed is:

1 . A discharge socket connecting a discharge port of a toilet main body and a discharge pipe including a bent portion disposed under a floor surface, comprising:
a vertical conduit portion, connected to the discharge port of a toilet main body, through which discharge water flows vertically downward from the discharge port of the toilet main body; and a bent conduit portion including an inflow port connected to the vertical conduit portion; an outflow port, connected to an inlet port of the discharge pipe, a center axis of the outflow port of the bent conduit portion being separated in the horizontal direction from a center axis of the vertical conduit portion; and a flow path through which the discharge water flows from the inflow port of the bent conduit portion to the outflow port of the bent conduit portion, the flow path having a bent portion which bends from the vertical conduit portion side toward the outflow port of the bent conduit portion; wherein a projecting portion is disposed on the bent portion of the bent conduit portion, the projecting portion forming a projecting space which projects outward from the flow path extending from an end portion on the side of the vertical conduit portion to a side other than the side of the vertical conduit portion, and the projecting portion is formed so that the flow direction of discharge water flowing from the bent conduit portion into the inlet portion of the discharge pipe is changed to the center direction of the discharge pipe by the discharge water returning to the projecting space after flowing from the flow path into the projecting space.

2 . The discharge socket according to claim 1 , wherein the projecting portion on the bent portion of the bent conduit portion is disposed on the opposite side from the side of the vertical conduit portion, sandwiching the center axis of the outflow port of the bent conduit portion.

3 . The discharge socket according to claim 1 , wherein the projecting portion on the bent portion of the bent conduit portion is disposed above the flow path along the center axis of the outflow port of the bent conduit portion.

4 . The discharge socket according to claim 1 , wherein the projecting portion on the bent portion of the bent conduit portion is disposed on the opposite side from the side of the vertical conduit portion, sandwiching the center axis of the outflow port of the bent conduit portion, and above a flow path along the center axis of the outflow port of the bent conduit portion.

5 . The discharge socket according to claim 2 , wherein volume of the projecting space in the bent conduit portion is greater than volume of a virtual cylinder formed inside the flow path by projecting an opening cross section in the horizontal direction of the outflow port of the bent conduit portion, from the height position of the bottom surface of the bent conduit portion to the height position at the height of the top surface of the bent conduit portion.

6 . The discharge socket according to claim 2 , wherein a pitched surface, sloping downward toward the outflow port of the bent conduit portion, is formed on the bottom surface of the projecting space of the bent conduit portion.

7 . A flush toilet comprising the discharge socket according to claim 1 .
