Abstract
This invention provides a low-profile water tank device for washing water, comprising a water supply valve for supplying washing water and a drain valve for discharging the washing water. The invention further comprises: a first connecting member and a second connecting member, each having one end connected to the drain valve; a rotating winding section connected to the other end of each of the first and second connecting members; and an operating section for rotating the rotating winding section in two directions. When the operating section rotates the rotating winding section in a first direction, the rotating winding section winds the first connecting member in that direction by a first amount, raising the drain valve by a first amount, thus performing a first washing mode for toilet cleaning. When the operating section rotates the rotating winding section in a second direction, the rotating winding section winds the second connecting member in that direction by a second amount, raising the drain valve by a second amount, thus performing a second washing mode for toilet cleaning.
