WASHING WATER TANK DEVICE AND FLUSH TOILET BOWL DEVICE EQUIPPED WITH THE SAME
To provide a washing water tank device that can return to a state where the next toilet bowl washing can be executed in a short time while opening the drain valve using water pressure.SOLUTION: A washing water tank device (4) comprises a water storage tank (10), a drain valve (12), a drain valve hydraulic drive unit (14) that drives the drain valve using water pressure of the supplied water, and a drainage/vacuum break valve device (30) provided on the upstream side of this drain valve hydraulic drive unit and supplying water supplied from the upstream side to the drain valve hydraulic drive unit on the downstream side. The drain valve hydraulic drive unit comprises a cylinder (14a) into which the water from the drainage/vacuum break valve device flows, and a piston (14b) that is moved by the pressure of the water flowing into the cylinder and moves the drain valve. The drainage/vacuum break valve device includes a valve body that operates to open the upstream side to the atmosphere and at the same time drain the water flowing back from the drain valve hydraulic drive unit when the water supply from the upstream side is stopped.SELECTED DRAWING: Figure 2
【課題】水圧を利用して排水弁の開弁を行いながら、短時間で次回の便器洗浄が実行可能な状態に復帰することができる洗浄水タンク装置を提供する。【解決手段】本発明は、洗浄水タンク装置(4)であって、貯水タンク(10)と、排水弁(12)と、供給された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)と、この排水弁水圧駆動部の上流側に設けられ、上流側から供給された水を、下流側の排水弁水圧駆動部に供給する排水／真空破壊弁装置(30)と、を有し、排水弁水圧駆動部は、排水／真空破壊弁装置からの水が流入するシリンダ(14a)と、シリンダに流入した水の圧力により移動され、排水弁を移動させるピストン(14b)と、を有し、排水／真空破壊弁装置は、上流側からの水の供給が停止されると、上流側を大気に開放すると同時に、排水弁水圧駆動部から逆流した水を排水するように作動する弁体を備えることを特徴としている。【選択図】図２
