A refrigerator includes a refrigerator main body having a storage chamber, a door coupled to the refrigerator main body to be opened or closed, a cool air supplying device which generates cool air, an ice maker including an ice making tray having ice making cells to produce ice and a cool air guide member installed in the door, coupled to the ice making tray and having a cool air line that guides the cool air supplied from the cool air supplying device to flow around the ice making tray. The cool air line disposed on the cool air guide member to supply the ice making tray guides the cool air supplied from the cool air supplying device to move along the surrounding of the ice making tray, thereby uniformly cooling down the ice making tray.

1. A refrigerator, comprising: a refrigerator main body having a storage chamber;a door coupled to the refrigerator main body to be opened or closed;a cool air supplying device installed at the refrigerator main body to generate cool air;an ice making compartment provided at a rear of the door;an ice maker installed in the ice making compartment provided at the rear of the door, the ice maker including an ice making tray to produce ice;a cool air discharge port provided on an upper wall of the refrigerator main body, the cool air discharge port disposed above the ice making compartment to discharge the cool air generated from the cool air supplying device downwardly toward the ice making compartment;a tray cover including an ice guide portion installed at a front discharge side of the ice making tray, which guides ice pieces discharged from the ice making tray by an elector into an ice storage container;a guide member coupled to the ice making tray to guide the cool air from the cool air discharge port to the ice making tray when the door is closed, the guide member including an upper distribution portion disposed above the ice making tray to allow the cool air flowing downward from the cool air discharge port to pass through openings formed in the upper distribution portion toward an upper side of the ice making tray, a rear distribution portion extending to a rear side of the ice making tray from the upper distribution portion to guide the cool air flowing downward from the cool air discharge port to the rear side of the ice making tray; anda partition wall is provided in the ice making compartment below the ice making tray in a spaced apart relationship such that the cool air flowing downward along the rear side flows between a bottom surface of the ice making tray and the partition wall to directly expose the bottom surface to the cool air, and then flows along the front side of the ice making tray through the tray cover,wherein the upper distribution portion of the guide member is spaced above the ice guide portion of the tray cover to allow ice pieces discharged from the ice making tray to pass between the upper distribution portion and the ice guide portion. 2. The refrigerator according to claim 1, wherein the guide member has an interior surface that serves to guide ice pieces being discharged from the ice making tray, and an exterior surface that serves to guide cool air to flow along the exterior surface of the ice making tray. 3. The refrigerator according to claim 1, wherein a plurality of holes are provided at the partition wall to flow out cool air drawn in a non discharge side of the ice making tray. 4. The refrigerator according to claim 3, wherein the cool air introduced from the cool air discharge port flows to the upper distribution portion, and flows to the non discharge side of the ice making tray, and flows to a lower portion of the ice making tray, and then flows downward through the holes of the partition wall. 5. The refrigerator according to claim 1, wherein the cool air discharge port is extended toward the door from the upper wall of the refrigerator main body, and an outlet of the cool air discharge port is inclined downward to flow cool air toward the ice making compartment. 6. A refrigerator, comprising: a refrigerator main body having a storage chamber;a door coupled to the refrigerator main body to be opened or closed;a cool air supplying device installed at the refrigerator main body to generate cool air;an ice making compartment provided at a rear of the door;an ice maker installed in the ice making compartment provided at the rear of the door, the ice maker including an ice making tray to produce ice;a cool air discharge port provided on an upper wall of the refrigerator main body, the cool air discharge port disposed above the ice making compartment to discharge the cool air generated from the cool air supplying device downwardly toward the ice making compartment;a tray cover including an ice guide portion installed at a front discharge side of the ice making tray, which guides ice pieces discharged from the ice making tray by an ejector into an ice storage container;a guide member coupled to the ice making tray to guide the cool air from the cool air discharge port to the ice making tray when the door is closed, the guide member including an upper distribution portion disposed above the ice making tray to allow the cool air flowing downward from the cool air discharge port to pass through openings formed in the upper distribution portion toward an upper side of the ice making tray, a rear distribution portion extending to a rear side of the ice making tray from the upper distribution portion to guide the cool air flowing downward from the cool air discharge port to the rear side of the ice making tray; anda partition wall is provided in the ice making compartment below the ice making tray in a spaced apart relationship such that the cool air flowing downward along the rear side flows between a bottom surface of the ice making tray and the partition wall to directly expose the bottom surface to the cool air, and then flows along the front side of the ice making tray through the tray cover,wherein the upper distribution portion of the guide member is spaced above the ice guide portion of the tray cover to allow ice pieces discharged from the ice making tray to pass between the upper distribution portion and the ice guide portion, andwherein the cool air discharge port is extended toward the door from the upper wall of the refrigerator main body, and an outlet of the cool air discharge port is inclined downward to flow cool air toward the ice making compartment. 7. The refrigerator according to claim 6, wherein a plurality of holes are provided at the partition wall to flow out cool air drawn in a non discharge side of the ice making tray, and wherein the cool air introduced from the cool air discharge port flows to the upper distribution portion, and flows to the non discharge side of the ice making tray, and flows to a lower portion of the ice making tray, and then flows downward through the holes of the partition wall.
