DETECTOR FOR SUSPENSION OF WATER SUPPLY IN TOILET BOWL

摘要

PROBLEM TO BE SOLVED: To prevent the break of seal water of a trap section even when a water supply solenoid valve is in an ON-state in the case of suspension of water supply. SOLUTION: A movable valve 11 for closing a water supply channel 8 in an OFF-state of a water supply solenoid valve 9 and for opening the water supply channel 8 driven by water flowing from the water supply solenoid valve 9 side in an ON-state of the water supply solenoid valve 9 of the water supply channel 8. A branch channel 12 is branched from the water supply channel 8 in a downstream side lower than the movable valve 11 of the water supply channel 8. The movable valve 11 is driven by water and is moved by interlocking with movability of the movable valve 11 to close the branch channel 12 in a state to open the water supply channel 8, and a second valve 13 capable of opening the branch channel 12 is provided when the movable valve 11 is in an OFF-position. A detector 14 for detecting the movement of the second valve 13 is provided, and when an ON-state of the second valve 13 is detected by the detector 14 in the case the water supply solenoid valve 9 is in an ON- state, a control section 15 for controlling a driving device 7 is so provided that the rear end used as the free end of the trap section is turned upward.
