  • Publication number: 20260146430
    Abstract: A siphon jet-type flush toilet apparatus includes a bowl, a drain trap conduit, a jet water spout port, a pressure pump, a line sensor that detects an object fallen into the bowl, and a control unit that determines whether the object is solid waste or floating waste. The control unit controls the pressure pump such that first jet water ejection is performed through the jet water spout port at a first flow rate for inducing siphonage and such that second jet water ejection is subsequently performed through the jet water spout port at a second flow rate lower than the first flow rate. The control unit controls the pressure pump such that the duration of the first jet water ejection is shorter when the object is determined to be floating waste than when the object is determined to be solid waste.
