URINAL AND URINAL FLUSHING CONTROL METHOD
A urinal and a urinal flushing control method. The urinal includes a urinal body, an electromagnetic valve for turning on and off flushing, a capacitive sensor for sensing a liquid amount on an outer wall of the urinal body, and a controller for receiving a capacitance value signal to control on and off of the electromagnetic valve. The controller sets a flushing timing reference point when determining that a capacitance value exhibits a dropping trend after a first period since the electromagnetic valve is controlled to be turned off, and controls to turn on the electromagnetic valve when the flushing timing reference point is present for a second period. The above solution can reduce the chance of erroneous flushing and facilitate the adaptability respect to the glazed surface of the urinal body.
