Summary:To provide a washing water tank device capable of accurately setting discharge timing of washing water without using any motor for lifting a drain valve.SOLUTION: A washing water tank device (4) comprises: a washing water tank body (10); a drain valve (12) that switches draining/stopping of washing water in the washing water tank body; a water pressure drive mechanism (14) for driving the drain valve using supply water pressure; a first on-off valve (19) for switching discharge/stop of washing water supplied from a water supply source; a second on-off valve (18) for supplying the washing water to the water pressure drive mechanism so that the drain valve is opened by the water pressure drive mechanism; and a control unit (28) for controlling the first on-off valve and the second on-off valve so as to open the first on-off valve and the second on-off valve to discharge the water from both of an upper water discharge port and a lower water discharge port at the same time.SELECTED DRAWING: Figure 3 【課題】排水弁を引き上げるためのモーターを使用することなく、洗浄水の吐出タイミングを正確に設定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、洗浄水タンク本体(10)と、この洗浄水タンク本体内の洗浄水の排出、停止を切り替える排水弁(12)と、給水圧により排水弁を駆動する水圧駆動機構(14)と、給水源から供給された洗浄水の吐出、停止を切り替える第1開閉弁(19)と、水圧駆動機構によって排水弁が開弁されるように、水圧駆動機構に洗浄水を供給するための第2開閉弁(18)と、第1開閉弁及び第2開閉弁を開弁させることにより、一時に上部吐水口及び下部吐水口の両方から吐水が行われるように、第1開閉弁及び第2開閉弁を制御する制御部(28)と、を有することを特徴としている。【選択図】図3
