Document Type and Number:
WIPO Patent Application WO/2011/159044
Kind Code:
A2
Abstract:
The present invention relates to a drain valve for opening and closing the water flow in a water tank for a toilet bowl, and more specifically, to a drain valve for rapidly closing the water flow to save the water consumed in a toilet bowl. The present invention rapidly closes a discharge hole after a predetermined amount of water filled in a water tank for a toilet bowl is discharged, thereby reducing the amount of water wasted by discharge. In addition, the present invention can allow the drain valve to be opened for a predetermined time even without a separate complex operational configuration or external power supply, thereby enabling smooth performance of the inherent function of a toilet bowl.
