Abstract: A water ejecting apparatus includes a case and a water ejection unit connected to one side of the case. The water ejection unit includes a fixed cover, a lifting cover, a lifting motor, a water ejection nozzle, a touch bar, a detection sensor, and a controller. The fixed cover is connected to the case. The lifting cover is movably received in the fixed cover and coupled to the lifting motor. The water ejection nozzle is installed at a lower end of the lifting cover and configured to eject water. The touch bar is at least partially received in the lifting cover and moves when in contact with a container placed below the water ejection nozzle. The detection sensor detects movement of the touch bar. The controller changes operation of the lifting motor when the detection sensor detects movement of the touch bar.
