Abstract:
1. A refrigerator comprising: a door mounted to a body having a refrigerating compartment, the door being configured to open and close at least a portion of the refrigerating compartment; an ice making compartment provided at the door; an ice making device arranged in the ice making compartment; an ice making tray provided at the ice making device and configured to receive and retain liquid to be frozen into ice; a cold air inlet provided at the ice making compartment and configured to allow cold air to be introduced into the ice making compartment; a cold air outlet provided at the ice making compartment and configured to allow cold air to discharge from the ice making compartment; a cold air guide configured to guide cold air entering the ice making compartment through the cold air inlet toward the ice making tray; a first cold air guide duct positioned to connect to the cold air inlet and introduce cold air through the cold air inlet to the ice making compartment; and a second cold air guide duct positioned to connect to the cold air outlet and receive cold air discharged from the ice making compartment through the cold air outlet, wherein the cold air inlet is positioned higher than the ice making tray and the cold air outlet is positioned lower than the ice making tray, wherein, when the door closes the refrigerating compartment, the first and second cold air guide ducts are respectively connected to the cold air inlet and the cold air outlet, wherein, when the door opens the refrigerating compartment, the first and second cold air guide ducts are respectively disconnected from the cold air inlet and the cold air outlet, wherein the cold air guide extends from the cold air inlet of the ice compartment to a position above the ice making tray and downwardly guides cold air to an upper portion of the ice making tray, wherein the cold air guide has an uppermost wall that defines an uppermost portion of the cold air guide, a lowermost wall that defines a lowermost portion of the cold air guide, side wall that define sides of the cold air guide, and a discharge hole that is defined by the uppermost wall, the lowermost wall, and the side walls, the uppermost wall, the lowermost wall, and the side walls defining a space through which air passes through the cold air guide from an inlet of the cold air guide to the discharge hole of the cold air guide, wherein higher portions of the side walls extend longer than lower portions of the side walls and the discharge hole has an inclined surface protruding from a perimeter of the discharge hole to the lowermost wall that causes uniform supply of cool air throughout the upper portion of the ice making tray.
