<p><P>PROBLEM TO BE SOLVED: To provide a drain pipe joint capable of reducing the risk of closing a water channel and reducing the risk of degradation. <P>SOLUTION: A piping joint 70 is the drain pipe joint to connect a drain pipe through which waste water from a hot water tank or water piping extending from the hot water tank flows, and includes a first receiving part 75, a discharge part 72 and an intermediate part 73. The first receiving part 75 receives water flowing through a first drain pipe. At the discharge part 72, a drain port 74 for discharging the water received from the first receiving part 75 to the outside is formed. The intermediate part 73 is interposed between the first receiving part 75 and the discharge part 72. Also, the intermediate part 73 is extended in a roughly horizontal direction. Further, the intermediate part 73 has a fifth water path 78 where the water discharged from the drain port 74 flows. Also, a bottom surface F of a second part 78b of the fifth water path 78 is inclined by a prescribed angle to a horizontal plane so that the side of the discharge part 72 becomes low. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
