Description

請求項４に記載の発明は、請求項１〜請求項３の何れか１項に記載の排水配管構造において、前記第１の排水配管と前記排水トラップとの間に、内周面に排水方向に対して交差する段差面が形成され前記段差面の排水方向下流側の内径が排水方向上流側の内径よりも相対的に小径とされた異径排水管が設けられている。 The invention according to claim 4 has a drainage direction on an inner peripheral surface between the first drainage pipe and the drainage trap in the drainage pipe structure according to any one of claims 1 to 3. different diameter drain pipe relatively small diameter is provided than the inside diameter inside diameter of the drainage direction downstream side of the drain the upstream side of the step surface intersect is formed a stepped surface against.

請求項４に記載の排水配管構造では、異径排水管の配管内に段差面を設けることで、管径が変化する部分で排水が抵抗を受けて渦の発生が抑制され、段差面の下流側の配管内を満流にし易くなり、サイホン力を迅速に発生させることができる。 The drain pipe structure according to claim 4, by providing the stepped surface in the pipe of different diameter drain pipe, generation of eddy receiving waste water resistance at a portion where the pipe diameter is changed is suppressed, downstream stepped surface It becomes easier to fill the inside of the pipe on the side, and siphon force can be generated quickly.
