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 time for lowering a float in association with drop of a water level to keep an instantaneous flow amount (L/min) of washing water drained from a drain port during small washing, relatively high, by changing buoyancy working on the float according to a selected 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 and 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 a 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 float is constructed so that buoyancy obtained during the small washing mode becomes smaller than the buoyancy obtained during the large 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、フロートに作用する浮力を変更することにより、水位低下に伴うフロートの下降時間を変更することができ、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、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、フロートは、小洗浄モード時に得られる浮力が大洗浄モード時に得られる浮力に比べて小さくなるように構成されている。【選択図】図３Ｂ
