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 keeping an instantaneous flow amount (L/min) of washing water drained from a drain port during small washing, relatively high, by changing a lowering speed of a float in association with drop of a water level in a water storage cylinder according to a selected large or small washing mode.SOLUTION: A drain valve device 1 includes a valve element 36, a working shaft 54, a water storage cylinder 62, and a float 72, where during a time from when the valve element is opened to when the valve element 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. The water storage cylinder or the float is constructed to change lowering speeds v1, v2 of the float in association with drop of a water level in the water storage cylinder according to the selected large or small washing mode.SELECTED DRAWING: Figure 3B
【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、貯水筒内の水位低下に伴うフロートの下降速度を変更することにより、小洗浄時において排水口から排出される洗浄水の瞬間流量［Ｌ／ｍｉｎ］を比較的高く維持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、作動軸５４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、貯水筒又はフロートは、選択された大洗浄モード又は小洗浄モードに応じて、貯水筒内の水位低下に伴うフロートの下降速度ｖ１，ｖ２を変更するように構成されている。【選択図】図３Ｂ
