Abstract: The present invention provides a flush toilet that is flushed with flush water to discharge waste, the flush toilet including a bowl that includes a waste receiving surface, a rim, and a well portion, a first spouting port that is formed in the rim and from which the flush water is spouted along an inner circumference surface of the rim, a first water passage that guides the flush water to the first spouting port, and a discharge conduit, wherein the first water passage includes a lower water passage formed into a vertically long rectangular shape, and an upper water passage having a smaller width than the width of the lower water passage and extending upward from the lower water passage, and a height dimension of the first spouting port is set to be substantially the same as the height dimension of the first water passage.

Abstract: A flush toilet according to the present invention includes a bowl including a bowl-shaped waste receiving surface, a rim, a spouting port formed in the rim and a pooled water portion having a front region and a rear region, and includes a configuration where a ratio of an inflow flow rate of flush water into the front region of the pooled water portion in a second half of flushing period in a flushing period to “a total inflow flow rate of flush water into the pooled water portion” is larger than a ratio of an inflow flow rate of flush water into the front region of the pooled water portion in a first half of flushing period to “the total inflow flow rate of flush water into the pooled water portion”.

Abstract: A flush toilet has a reservoir tank, a toilet main unit, a water supply apparatus, a water discharge apparatus, and a control device for controlling flushing of the bowl portion of the toilet main unit; wherein this control device includes a time measurement device for measuring the time after the water discharge apparatus has been driven for a predetermined time to discharge flush water, until the water level rises from a dead water level inside the reservoir tank with the water discharge apparatus in an off state to a predetermined stopped water level prior to start of flush; and the driving time of the water discharge apparatus responsive to pressure losses in the toilet main unit is adjusted by comparing the water level rise time measured by the time measurement device with the water level rise time in a standard toilet.
