洗净水箱装置及具备该洗净水箱装置的冲水大便器
摘要：
本发明提供一种洗净水箱装置，即使因节水化而减少向便器供给的洗净水量，也能削减追加水，可以置换浮子内的空气而使浮子正常进行动作。本发明的洗净水箱装置具有：洗净水供给装置，对洗净水向贮水箱内的供水及止水进行切换；小水箱，安装于该洗净水供给装置并贮存洗净水；开闭阀，开闭该小水箱的底面的开口部；浮子，可根据小水箱内的水位变动而上下移动；及排水阀装置，开闭贮水箱的排水口，开闭阀具备根据小水箱内的水位变动而上下移动的辅助浮子部，在小水箱内的水位经过排水阀装置封闭排水口时或在此之后的水位位置后，使小水箱内的水位下降的速度加快，使从小水箱的开口向贮水箱内排出的洗净水的流量增加。
