WASHING WATER TANK DEVICE AND FLUSH TOILET BOWL INCLUDING THE WASHING WATER TANK
PROBLEM TO BE SOLVED: To provide a washing water tank device capable of effectively preventing deterioration of a closing force of a drain valve body caused by buoyancy of a float acting on the drain valve body in a state where a drain port is closed.SOLUTION: A washing water tank device 18 includes a drain valve device 28 for opening/closing a drain port 22a of a water storage tank 22 and for performing supply of washing water to a flush toilet bowl 1. This drain valve device includes: a cylindrical body 72 extending upward in the vertical direction from a bottom surface of the water storage tank so as to surround the drain port; a control cylinder 46 arranged in the cylindrical body; a float 74 arranged in the control cylinder; a drain valve body 68 constituted so as to descend being interlocked with the descending of the float and for closing the drain port; and a locking/locking releasing mechanism 82 for locking the float to the control cylinder so that the closing force of the drain valve body does not deteriorate caused by buoyancy of the float acting on the drain valve body in a state where the drain valve body is closing the drain port, and for releasing the locking of the float with respect to the control cylinder when the drain valve body is opened.SELECTED DRAWING: Figure 6
【課題】排水口を閉止した状態の排水弁体にフロートの浮力が作用して排水弁体の閉止力を低下させることを効果的に防ぐことができる洗浄水タンク装置を提供する。【解決手段】本発明の洗浄水タンク装置１８は、貯水タンク２２の排水口２２ａを開閉して水洗大便器１への洗浄水の供給を行う排水弁装置２８を有し、この排水弁装置は、排水口を取り囲むように貯水タンクの底面から鉛直方向上方に延びる筒体７２と、この筒体の内方に配置された制御筒４６と、この制御筒内に配置されるフロート７４と、このフロートの下降に連動して下降して排水口を閉止するように構成された排水弁体６８と、この排水弁体が排水口を閉止している状態でフロートの浮力が排水弁体に作用して排水弁体の閉止力を低下させないようにフロートを制御筒に係止し、排水弁体が開弁すると制御筒に対するフロートの係止を解除する係止／係止解除機構部８２と、を備えている。【選択図】図６
