<p><P>PROBLEM TO BE SOLVED: To provide a toilet flush tank equipped with a hand washing basin that can inexpensively and reliably prevent scattering of washing water, which is problematic specifically in that the washing water discharged from a washing water discharge pipe is scattered around from a lower end of a discharge port of a washbasin. <P>SOLUTION: The present invention provides a toilet flush tank fixed to a toilet bowl body. The toilet flush tank comprises: an outer lid having a washbasin formed on its upper surface and having a first discharge port formed therein for supplying washing water from a washing water discharge pipe to an interior tank; and an inner lid having a second discharge port formed therein for supplying washing water from the first discharge port to the interior tank. The first discharge port is formed to protrude downward with respect to the back surface of the outer lid while the second discharge port is formed to protrude upward with respect to the upper surface of the inner lid. The inner diameter of the second discharge port is greater than the outer diameter of the first discharge port while the upper end of the second discharge port is located higher than the lower end of the first discharge port. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
