DRAINAGE STRUCTURE FOR BATHROOM UNIT
To provide a drainage structure for a bathroom unit which can smoothly perform drainage from a bathtub even when water level in the bathtub is low.SOLUTION: A drainage structure for a bathroom unit performs drainage from a bathtub and a waterproof pan, and includes a drain valve 1 for the bathroom unit. The drain valve 1 for the bathroom unit comprises: a main body 2 including a bathtub side drain hole 3 and a waterproof pan side drain hole 4; and a closing plate 5 including a bent portion 51 rotatably supported below the main body 2 in which closing portions 52 and 53 can close the drain holes 3 and 4 alternately by an oscillation at the bent portion 51 as a base point. The closing plate 5: when drainage from the bathtub is not performed and when drainage from the bathtub is completed, closes the drain hole 3 and opens the drain hole 4; when water level L in the bathtub is higher than a predetermined water level Ls and drainage from the bathtub is performed, opens the drain hole 3 and closes the drain hole 4; and then, when the water level L becomes equal to or lower than a preset water level Ls, gradually closes the drain hole 3 and opens the drain hole 4 in accordance with lowering of the water level L, until drainage from the bathtub is completed.SELECTED DRAWING: Figure 4B
【課題】浴槽内の水位が低いときも、当該浴槽からの排水をスムーズに行うことができる浴室ユニットの排水構造を提供する。【解決手段】浴室ユニットの排水構造は、浴槽及び防水パンからの排水を行い、浴室ユニット用排水弁1を有する。浴室ユニット用排水弁1は、浴槽側排水孔3と、防水パン側排水孔4とを有する本体2と、本体2の下方に回転可能に支持された折曲部51を有し、当該折曲部51を基点とした揺動により、閉塞部52及び53が、排水孔3及び4を交互に閉じることができる閉塞板5とを備えている。閉塞板5は、浴槽からの排水を行わない場合及び浴槽からの排水が完了した場合、排水孔3を閉じていると共に排水孔4を開いており、浴槽内の水位Lが所定水位Lsよりも高い水位で、前記浴槽からの排水が行われると、排水孔3を開くと同時に排水孔4を閉じ、次いで、水位Lが設定水位Ls以下になると、前記浴槽からの排水が完了するまで、水位Lの低下に従って、排水孔3を閉じていきつつ排水孔4を開いていく。【選択図】図4B
