Patent ID: 7762092

Claim:
A refrigerator comprising a refrigerator body having a freezing compartment defined therein, an evaporator mounted at a rear part of the freezing compartment, a guide duct mounted in front of the evaporator to disperse and supply cool air to upper and lower parts of the freezing compartment, and an ice making device including an ice making tray to receive water to be frozen, wherein the ice making tray has ice making grooves opened at the upper sides thereof to receive water and a cool air flow channel disposed below the ice making grooves and along which cool air flows, the ice making tray is rotatably connected to an ice separating motor to generate a rotating force such that the ice making tray is turned upside down, the ice making device further includes a cool air guide pipe selectively connectable to the cool air flow channel such that the cool air is supplied to the cool air flow channel only when the ice making tray is positioned with the ice making grooves upward, and the ice making tray includes an ice making part having the ice making grooves and a cool air guide part to cover a lower surface of the ice making part while being located a predetermined distance from the lower surface of the ice making part such that the cool air flow channel is defined between the ice making part and the cool air guide part, the cool air guide part having an inlet port, formed at one side thereof, to which a cool air guide pipe is connected such that the cool air is supplied to the cool air flow channel through the inlet port, and an outlet port formed, at the other side thereof, through which the cool air is discharged.
