DRAIN VALVE DEVICE, AND ONE-PIECE FLUSH TOILET BOWL EQUIPPED WITH DRAIN VALVE DEVICE
PROBLEM TO BE SOLVED: To provide a drain valve device capable of supplying washing water of a high instantaneous flow rate from a washing water tank to a toilet bowl, improving washing performance of the toilet bowl, and meanwhile, being commonly applied to various kinds of toilet bowls and washing water tanks.SOLUTION: A drain valve device 1 of the present invention includes: a drain part body member 48 which is attached to a drain port 10 and forms a drain passage 50 therein for guiding washing water from an inflow port 50b formed on one end thereof to an outflow port 50a formed on the other end thereof; a valve body 34 for opening and closing the inflow port of the drain part body member; and a fixing part 58 which is formed so as to protrude into the drain passage of the drain part body member and fixes the drain part body member to a water tank 8. In the drain passage of the drain part body member, an inner side surface 52c of a side wall part 52 where the height is the same as that of the fixing part, forms a curved part 76 which curves outward so as to enlarge a cross-sectional area S2 of the drain passage.SELECTED DRAWING: Figure 11
【課題】洗浄水タンクから便器に高い瞬間流量の洗浄水を供給することができ、便器の洗浄性能を向上させることができると共に、種々の便器や洗浄水タンクに対しても共通化させて適用することができる排水弁装置を提供する。【解決手段】本発明の排水弁装置１は、排水口１０に取り付けられ、その一端に形成される流入口５０ｂから他端に形成される流出口５０ａまで洗浄水を導く排水流路５０を内側に形成する排水部本体部材４８と、この排水部本体部材の流入口を開閉するための弁体３４と、排水部本体部材の排水流路内に突出するように形成され、排水部本体部材を貯水タンク８に固定する固定部５８と、を有し、この固定部と同じ高さにある排水部本体部材の排水流路の側壁部５２の内側面５２ｃは、流路の断面積Ｓ２を拡大するように外側に湾曲する湾曲部７６を形成している。【選択図】図１１
