Abstract
To provide a flush toilet device capable of optimally flushing the toilet according to the waste state at each toilet flush, thereby achieving further water saving and improved waste discharge performance.SOLUTION: The present invention comprises a bowl portion 15 having a waste receiving surface 12 and a rim portion 14, a drain trap pipe 16, a water discharge unit in the bowl portion 15 and discharging flush water, a pressure pump 10 supplying flush water to this jet water discharge port 20a, a waste information acquisition unit acquiring information about waste excreted in the bowl portion 15, and a control unit 74 which determines the waste state from this information about the waste and controls the flush water supply device based on this determination result. The control unit 74 controls the flush water supply device based on the determination result of the waste state at each toilet flush, thereby changing the discharge mode of flush water discharged from the water discharge unit.SELECTED DRAWING: Figure 5
