Abstract:
To provide a water closet unit which can suppress the variation of washing water volume supplied with a pump device from a flush tank to a closet body due to the difference in pressure loss in a water passage of an individual closet body.SOLUTION: A water closet unit is equipped with a closet body, a flush tank to contain washing water to wash the closet body, a pump device to supply the washing water in the flush tank into the closet body, and a control device which can detect an electric current value of the pump device and controls the pump device. The control device consists of: a flow volume estimation mode which estimates the flow volume of the washing water supplied to the closet body with the pump device based on the electric current value of the pump device; and a designated water volume supply mode which supplies a designated volume of the washing water to the closet body by adjusting the running period of the pump device to supply the designated volume of the washing water based on the flow volume of the washing water estimated in the flow volume estimation mode.SELECTED DRAWING: Figure 4
