ODOR-BLOCKING VALVE STRUCTURE
To provide an odor-blocking valve structure that allows easy attachment and detachment of an odor-blocking valve to a drain pipe.SOLUTION: An L-shaped slit is provided in a wall forming a drain outlet, extending from the downstream end of the wall in the upstream direction and then in the circumferential direction, an odor-blocking valve comprises a circular tubular body part having an outer peripheral dimension the same as the inner periphery of the drain outlet, and a cover part supported pivotally on the body part to close the outlet of the body part, a protruding stopper piece is provided on the outer periphery of the downstream end portion of the body part, and the odor-blocking valve is attached by aligning the stopper piece with the slit, inserting it into the drain outlet, and then rotating it so that the stopper piece engages with the slit.SELECTED DRAWING: Figure 4
【課題】排水管に対して、防臭弁を容易に着脱可能とする。【解決手段】排水口を形成する壁に、前記壁の下流側端から上流方向に進んだ後に円周方向に進むＬ字形の切れ込みが設けられており、前記防臭弁は、前記排水口の内周と同じ外周寸法を有する円管状の本体部と、前記本体部に揺動自在に支持されて前記本体部の出口を塞ぐ蓋部を有するとともに、前記本体部の下流側端部に外周に突出するずれ止め片が設けられており、前記ずれ止め片と前記切れ込みとの位置合わせをして、前記排水口に挿入した後に回動させることで、前記ずれ止め片が前記切れ込みに係合されて取り付けられる。【選択図】 図４
