DRAIN VALVE DEVICE
To provide a drain valve device that can reduce variations of a dead water level.SOLUTION: A drain valve device according to an embodiment is provided with a drain valve body, a float, and an engagement portion. The drain valve body is equipped with a valve body spindle extending upward, and opens and closes a drain port of a washing water tank which stores washing water in response to the lifting of the valve body spindle. The float moves up and down in conjunction with the water level in the washing water tank. The engagement portion is capable of engaging with an engaging protrusion provided on the valve body spindle, and can be disengaged from the engaging protrusion by a rotational movement about the axis of rotation. The engagement portion also has a rotational axis at a position farther from the valve body spindle than the position where it engages with the engaging protrusion. When the water level in the washing water tank is above a predetermined level, the rotation of the engagement portion is restricted by abutting on the float from the side, and when the water level in the washing water tank is below a predetermined level, the rotation of the engagement portion is allowed to move as the float is lowered.SELECTED DRAWING: Figure 5
【課題】死水水位のばらつきを抑えることができる排水弁装置を提供する。【解決手段】実施形態に係る排水弁装置は、排水弁体と、フロートと、係合部とを備える。排水弁体は、上方に延在する弁体主軸を備え、洗浄水を貯留する洗浄水タンクの排水口を弁体主軸の引き上げに応じて開閉する。フロートは、洗浄水タンクの水位に連動して上下動する。係合部は、弁体主軸に設けられた係合突起と係合可能であり、回転軸を中心とした回転動作によって係合突起との係合を解除可能である。また、係合部は、係合突起との係合位置よりも弁体主軸から遠い位置に回転軸を有し、且つ、洗浄水タンクの水位が所定水位よりも上である時、フロートに側方から当接することによって回転動作が規制され、洗浄水タンクの水位が所定水位以下の時、フロートの下降に伴って回転動作が許容される。【選択図】図５
