PURPOSE: An apparatus for opening/closing a powerless waterline, in which an automatic flush is possible by users' weight is provided to make the flush smoothly operated even if the users use a toilet bowl for a short time. CONSTITUTION: An apparatus for opening/closing a powerless waterline, in which an automatic flush is possible by users' weight comprises a flush valve(100) and a flushing unit(300). The flush valve stores water flowing through a waterline opened by users' weight. The flush valve closes the waterline when the users get up from a toilet bowl seat(10), and supplies the water to the flushing unit. An expansion member of the flushing unit is expanded by the pressure of the water supplied from the flush valve, and opens a drain by rotating a siphon cover(21). Washing water is discharged through the opened drain. |
