초록 ▼

A toilet bowl flushing device controls the rate of flow of flushing water supplied to a toilet bowl so that the toilet bowl can be washed out with a minimum amount of flushing water for a maximum flushing effect. The toilet flushing device includes a water supply system for supplying flushing water through a water supply pipe to a toilet bowl, a flow rate control valve disposed in the water supply pipe, for varying the rate of flow of flushing water supplied to the toilet bowl through control of the opening of the valve, an actuator for actuating the flow rate control valve, and a controller for controlling operation of the actuator. The controller controls operation of the actuator to vary the opening of the valve stepwise with time in one flushing cycle according to a predetermined flow rate pattern so that the flushing water is supplied toilet bowl at a flow ate which varies stepwise with time.
