Method for controlling refrigerator

A refrigerator comprising:

• an ice making device;
• 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;
• and
• a controller configured to perform operations comprising:
• starting water supply to the ice making device;
• 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.

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
• in response to a determination that the detected pulse value has not reached the target pulse value within the preset time:
• setting a new target pulse value based on the detected pulse value;
• and
• supplying additional water to the ice making device until the new target pulse value has been reached.
