WASHING WATER TANK DEVICE AND FLUSH TOILET BOWL DEVICE EQUIPPED WITH THE SAME
To provide a washing water tank device and a flush toilet device equipped with the same, wherein the washing water tank device can reduce the risk that a drain valve hydraulic drive part malfunctions.SOLUTION: A washing water tank device of the present invention comprises: a water storage tank 10; a drain valve 12 that opens and closes an exhaust port to supply and stop washing water to a flush toilet bowl; and a drain valve hydraulic drive part 14 that drives the drain valve by using the water supply pressure of the supplied tap water, the drain valve hydraulic drive part 14 having a cylinder 14a to be supplied with the tap water as the washing water, a piston 28 that is slidably arranged in the cylinder and is moved from a first position to a second position by the washing water flowing into the cylinder, and a seal member 20 that is provided on the piston and has a sealing function between the piston and an inner wall of the cylinder. When the piston 28 is in the first position H1, a lower end of the seal member 20 is located above a water-stop water level WL of the water storage tank 10.SELECTED DRAWING: Figure 6
【課題】排水弁水圧駆動部が動作不良となる可能性を低減できる洗浄水タンク装置、及びそれを備えた水洗便器装置を提供する。【解決手段】本発明の洗浄水タンク装置は、貯水タンク１０と、排水口を開閉し、水洗便器への洗浄水の供給、停止を行う排水弁１２と、供給された水道水の給水圧を利用して、排水弁を駆動する排水弁水圧駆動部１４であって、水道水が洗浄水として供給されるシリンダ１４ａと、シリンダ内に摺動可能に配置されると共に、洗浄水がシリンダ内に流入することにより第１の位置から第２の位置に移動されるピストン２８と、ピストンに設けられると共にピストンとシリンダの内壁との間のシール機能を有するシール部材２０と、を備える排水弁水圧駆動部１４とを備え、ピストン２８が第１の位置Ｈ１にある場合に、シール部材２０の下端が、貯水タンク１０の止水水位ＷＬより上方に位置する。【選択図】図６
