First Claim
Patent Images
1. An ice-making device for a refrigerator, the ice-making device comprising:
- an ice tray configured to receive water therein and convert to ice pieces from the water; and
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 an evaporator of the refrigerator to flow under the ice tray,wherein the ice tray comprises a lower surface comprising uneven portions extending in a direction different from a flow direction of the cold air.

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.
