DRAIN VALVE DEVICE, WASHING WATER TANK DEVICE, AND WATER CLOSET
To provide a drain valve device, a washing water tank device, and a water closet capable of changing a lowering speed of a float in association with drop of a water level in a water storage cylinder by changing a washing water amount (so called, draining capacity) that washing water in the water storage cylinder flows out from an outflow hole into a washing water tank according to a selected a large or small washing mode.SOLUTION: A drain valve device 1 includes a valve element 36, a water storage cylinder 62, and a float 72, where during a time from when the valve element is opened to when the same is closed, either a large washing mode that washing water in a water storage tank 12 is supplied from a drain port 18 to a water closet 4 at a first washing water amount or the small washing mode that the washing water is supplied at a second washing water amount smaller than the first washing water amount can be selectively executed. A first total outflow amount Q1 of washing water in the water storage cylinder 62 when flowing out from the outflow hole 72 to the water storage tank in the large washing mode is larger than a second total outflow amount Q2 of the washing water in a water storage cylinder body 68 when flowing out from the outflow hole to the water storage tank in the small washing mode.SELECTED DRAWING: Figure 6B
【課題】選択された大洗浄モード又は小洗浄モードに応じて、貯水筒内の洗浄水が流出穴から洗浄水タンクに流出する洗浄水量（いわゆる「水抜け量」）を変更し、貯水筒内の水位低下に伴うフロートの下降速度を変更することができる排水弁装置、洗浄水タンク装置、及び、水洗大便器を提供する。【解決手段】本発明の排水弁装置１は、弁体３６と、貯水筒６２と、フロート７２と、を有し、弁体が開弁してから閉弁するまでの間、貯水タンク１２内の洗浄水が排水口１８から水洗大便器４に第１洗浄水量で供給される大洗浄モード又は第１洗浄水量よりも少ない第２洗浄水量で供給される小洗浄モードのいずれかの洗浄モードが選択的に実行可能であり、大洗浄モードにおいて貯水筒６２内の洗浄水が流出穴７２から貯水タンクに流出する第１総流出量Ｑ１は、小洗浄モードにおいて貯水筒本体６８内の洗浄水が流出穴から貯水タンクに流出する第２総流出量Ｑ２よりも大きい。【選択図】図６Ｂ
