DRAIN VALVE OPERATION DEVICE
PROBLEM TO BE SOLVED: To provide a drain valve operation device for enabling the draining of an approximately full amount of washing water stored in a washing water tank with a one-time operation command.SOLUTION: An operation command signal is issued once with one-time operation by an operator (Fig.3:Step S503). Then, a flapper valve 20 is opened to start draining, thus causing a lower water level in a washing water tank 10 to lead the flapper valve 20 to be closed. A second control signal, however, is issued before the flapper valve 20 is closed (Fig.3:Step S505). So, the flapper valve 20 is opened again to almost completely drain washing water residing in the washing water tank 10.SELECTED DRAWING: Figure 3
【課題】洗浄水タンク内に貯留した洗浄水を一度の操作指令で略全量排水することが可能な排水弁操作装置を提供すること。【解決手段】操作者による１回の操作によって一旦操作指令信号が発せられると（図３：ステップＳ５０３）、この後、フラッパー弁２０が開弁して排水が始まり、洗浄水タンク１０の水位が下降して、フラッパー弁２０が閉弁に至ろうとするが、フラッパー弁２０が閉弁してしまう以前に、第２制御信号を発して（図３：ステップＳ５０５）、再度フラッパー弁２０を開弁させて、洗浄水タンク１０に残留している洗浄水を略完全に排水させる。【選択図】図３
