Abstract:
1. A flush toilet flushed by pressurized flush water, comprising: a flush toilet main body furnished with a bowl portion on which a rim water spouting port and a jet water spouting port are formed, and a drain trap pipe; a pressurizing pump for pressurizing flush water spouted from the jet water spouting port; a holding tank for holding flush water to be pressurized by the pressurizing pump; flush control means for causing flush water to be spouted from the rim water spouting port for a predetermined rim spouting time using water main supply pressure, and for flushing the bowl portion by causing a predetermined jet spouting volume of flush water in the holding tank to be spouted from the jet spouting port using the pressurizing pump; flush water replenishment means for supplying flush water from the water main to the holding tank after flushing the bowl portion, thereby restoring the volume of water held in the holding tank to a predetermined pre-flush held water volume; clock means for detecting the water replenishment time starting from the commencement of flush water supply by the flush water replenishment means until the volume of water held in the holding tank is restored to the predetermined held water volume; and water spouting time adjustment means for adjusting the rim spouting time during which flush water is spouted from the rim water spouting port by the flush control means, based on the water replenishment time detected by the clock means.
