DRAIN VALVE DEVICE, WASHING WATER TANK DEVICE AND WATER CLOSET
To provide a drain valve device that can suppress malfunction of a valve body to stabilize opening and closing of an exhaust port.SOLUTION: The drain valve device according to one aspect of an embodiment comprises a valve body, a float, a pedestal, and a plurality of pillar sections. The valve body is arranged above the exhaust port formed on a bottom surface of a washing water tank and moves in a vertical direction to open and close the exhaust port. The float lowers the valve body in conjunction with decrease in a water level in the washing water tank. The pedestal is arranged above the exhaust port and is fixed by fastening at a plurality of fixed positions near the exhaust port with respect to the bottom surface. The pedestal has ribs. The ribs project downward toward a peripheral edge of a lower surface of the pedestal. A notch is formed in the rib. The plurality of the pillar sections are arranged at predetermined intervals on an outer peripheral part of the valve body on the upper surface of the pedestal to guide movement of the valve body.SELECTED DRAWING: Figure 5
【課題】弁体の動作不良を抑制して排水口の開閉を安定させること。【解決手段】実施形態の一態様に係る排水弁装置は、弁体と、フロートと、台座と、複数の柱部と、を備える。弁体は、洗浄水タンクの底面に形成された排水口の上方に配置され上下方向に移動して排水口を開閉する。フロートは、洗浄水タンク内の水位の低下に連動して弁体を下降させる。台座は、排水口の上方に配置され、底面に対して排水口近傍の複数の固定位置において締結により固定される。台座は、リブを有する。リブは、台座の下面の周縁部に下方に向けて突出する。リブには切り欠き部が形成される。複数の柱部は、台座の上面における弁体の外周部に所定間隔をあけて配置され弁体の移動をガイドする。【選択図】図５
