Flush toilet apparatus

A flush toilet apparatus that is a siphon jet-type flush toilet apparatus, the flush toilet apparatus comprising:

• a bowl having a waste receiving surface and a rim portion, the waste receiving surface being configured to receive waste, and the rim portion being formed above the waste receiving surface;
• a drain trap conduit connected to a lower portion of the bowl and configured to discharge waste;
• a jet water spout port provided at a lower portion of the bowl and configured to eject flush water toward an inlet of the drain trap conduit;
• a flush water supply device configured to supply flush water to the jet water spout port;
• a detection unit configured to detect an object fallen into the bowl;
• and
• a control unit that is configured to perform a determination of whether the object is solid waste or floating waste based on a detection result obtained by the detection unit and to control the flush water supply device based on a result of the determination,
• wherein the control unit is configured to control the flush water supply device 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, and
• wherein the control unit is configured to control the flush water supply device such that an instantaneous flow rate in the first jet water ejection is higher when the object is determined to be floating waste than when the object is determined to be solid waste.
