Abstract:
1. A method comprising: starting water supply to an ice making device in a refrigerator, the ice making device including a flow sensor configured to detect water supply flow to the ice making device by using a pulse value according to rotation of an impeller; after starting the water supply, operating the flow sensor to detect a pulse value; accessing a target pulse value; comparing the detected pulse value to the target pulse value; based on comparison results, determining whether the detected pulse value has reached the target pulse value within a preset time; and based on a determination that the detected pulse value has not reached the target pulse value within the preset time, determining that water supply to the ice making device is in a low water-pressure state and performing a water supply control process according to the low water-pressure state, the water supply control process according to the low water-pressure state comprising: calculating a measurement of water supplied to the ice making device based on the detected pulse value for the preset time; determining a measurement of additional water needed to reach a target; setting a new target pulse value corresponding to the measurement of additional water needed to reach the target; and supplying additional water to the ice making device until the new target pulse value has been reached.
