1. An ice-making device for a refrigerator, the ice-making device comprising:
- an ice tray configured to receive water therein and convert the water to ice pieces, the ice tray comprising a lower surface;
a duct located under the ice tray and configured to receive a cold air from an evaporator and provide a flow path for cold air supplied from the evaporator to flow under the ice tray; and
ribs protruding outward from the lower surface of the ice tray,wherein the lower surface of the ice tray comprises uneven portions extending in a direction different from a lengthwise direction of the ice tray,the ribs are continuously extended in a wavy shape along the lengthwise direction of the ice tray,the duct comprises at least two separation walls extending along the lengthwise direction of the ice tray,each of the separation walls includes a first separation wall protruding downward from the lower surface of the ice tray, andthe uneven portions are provided between the ribs and between the rib and the first separation wall.

Abstract
An ice-making device for a refrigerator including a duct providing a cold air flow path under an ice tray in which water turns into ice pieces. Uneven portions extending in a direction differing from a flow direction of cold air are formed at a lower surface of the ice tray. The duct may have a wavy surface. The surface features of the ice tray and the duct can advantageously increase contact area and contact time between cold air and the ice tray, thereby increasing the heat exchange efficiency between cold air and water contained in the ice tray.
