WASHING WATER TANK DEVICE AND FLUSH TOILET BOWL DEVICE EQUIPPED WITH THE SAME
To provide a washing water tank device capable of suppressing variations in washing performance by stabilizing operation of a drain valve.SOLUTION: A washing water tank device (4) of the present invention comprises: a washing water tank body (10); a water supply valve (19) that allows washing water supplied from a water supply source to flow into the washing water tank body; and a drain valve (12) that is installed inside the washing water tank body, and switches between draining and stopping the washing water stored in the washing water tank body to a flush toilet bowl by opening and closing a drain port (10a), wherein the drain valve is kept open until a water level in the washing water tank body drops from a predetermined full water level (L1) to a predetermined dead water level (L3) when washing the flush toilet bowl, a lowering speed of the water level in the washing water tank body changes at a predetermined inflection water level (L2) between the full water level and the dead water level, and a lowering speed of the water level between the inflection water level and the dead water level is faster than a lowering speed of the water level between the full water level and the inflection water level.SELECTED DRAWING: Figure 4
【課題】排水弁の動作を安定させることにより、洗浄性能のばらつきを抑制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、給水源から供給された洗浄水を洗浄水タンク本体内に流入させる給水弁(19)と、この洗浄水タンク本体内に設けられ、排水口(10a)を開閉することにより、洗浄水タンク本体内に貯留された洗浄水の、水洗大便器への排水、停止を切り替える排水弁(12)と、を有し、排水弁は、水洗大便器の洗浄時において、洗浄水タンク本体内の水位が、所定の満水水位(L1)から所定の死水水位(L3)に低下するまで開弁されると共に、洗浄水タンク本体内の水位の低下速度は、満水水位と死水水位の間の所定の変曲水位(L2)において変化し、変曲水位と死水水位の間の水位の低下速度は、満水水位と変曲水位の間の水位の低下速度よりも速いことを特徴としている。【選択図】図４
