Abstract
Provided is a flush toilet apparatus having a flush toilet main body that includes a bowl, a water discharge trap pipe, an upper water discharge port, a lower water discharge port, and a flush control device configured to execute both a large flush mode and a small flush mode. When in operation, the flush control device causes flush water to be discharged from the lower water discharge port with substantially the same amount in each of the large flush mode and the small flush mode to induce a siphon phenomenon in the water discharge trap pipe. The device also controls water discharge from the upper water discharge port so that a water level of pooled water in the bowl during the water discharge from the lower water discharge port is changed between the large flush mode and the small flush mode.
