PASSAGE SWITCHING DEVICE
PROBLEM TO BE SOLVED: To provide a passage switching device capable of reliably supplying refill water even when it is installed in a water supply passage for a siphon bedpan.SOLUTION: A flash valve SV, which is a passage switching device, performs main washing operation of opening a main valve by opening a first auxiliary valve provided in a bypass channel, and performs refill water supply operation without opening a main valve, by opening a second auxiliary valve provided in a refill water supply channel after closing the first auxiliary valve to end the main washing operation.
【課題】サイフォン便器への水供給流路に取り付けた場合であっても、確実にリフィル水を供給可能な流路開閉装置を提供すること。【解決手段】流路開閉装置であるフラッシュバルブＳＶは、バイパス流路に設けられた第１副バルブを開くことで、主バルブを開く主洗浄動作を行い、その後、第１副バルブを閉じて主洗浄動作が終了した後、リフィル水補給流路に設けられた第２副バルブを開くことで、主バルブを開くことなくリフィル水供給動作を実行する。【選択図】 図２
