Abstract: A refrigerator includes a cabinet that includes a refrigerator compartment and a freezer compartment. The refrigerator includes a refrigerator compartment door that is located at a left or a right side of the refrigerator compartment, wherein an ice maker and a dispenser are located at the refrigerator compartment door. The refrigerator includes a main water tank that is located in the refrigerator compartment, and that is configured to cool water. The refrigerator includes a water purifying device that is located at the cabinet, and that is configured to purify water. The refrigerator includes a sub-water tank that is located on the refrigerator compartment door, and that is configured to additionally cool water cooled by the main water tank. The refrigerator includes a water supply path that is defined by connections between the water purifying device, the main water tank, the sub-water tank, the dispenser, and the ice maker.
