Abstract

The present invention relates to a cold air guide structure of an ice-making chamber of a cold chamber door. The structure including: the cold chamber door; an insulation case disposed inside of the cold chamber door, thermally insulated and having an ice-making chamber therein; an ice-making unit installed in the ice-making chamber of the insulation case, for icing a supplied water by an ice-making cold air and housing pieces of ice; an insulation cover for opening and closing the ice-making chamber of the insulation case; a cold air inlet port for sucking the ice-making cold air into the ice-making chamber; a cold air outlet port for exhausting the ice-making cold air from the ice-making chamber; and an ice-making cold air guide unit for guiding the ice-making cold air to a predetermined air passage to suck or exhaust the ice-making cold air into or from the ice-making chamber.

Claims

1. A cold air guide structure of an ice-making chamber of a cold chamber door, the structure comprising:

the cold chamber door;

an insulation case disposed inside of the cold chamber door, thermally insulated and having an ice-making chamber therein;

an ice-making unit installed in the ice-making chamber of the insulation case, for icing a supplied water by an ice-making cold air and housing pieces of ice;

an insulation cover for opening and closing the ice-making chamber of the insulation case;

a cold air inlet port for sucking the ice-making cold air into the ice-making chamber;

a cold air outlet port for exhausting the ice-making cold air from the ice-making chamber;

a cold air supply duct disposed inside wall of the cold chamber, supplied to the cold air through the cold air outlet port.

an ice-making cold air guide unit for guiding the ice-making cold air to a predetermined air passage to suck or exhaust the ice-making cold air into or from the ice-making chamber.

2. The structure according to claim 1, wherein the ice-making cold air guide unit is a bypass from the ice-making chamber to the cold air outlet port.

3. The structure according to claim 1, wherein the ice-making cold air guide unit has an ice-making cold air guide duct defined along an inner wall of the insulation case, for discharging the ice-making cold air.

4. The structure according to claim 3, wherein the ice-making cold air guide duct connects a cold air exhaust port and the cold air outlet port.

5. The structure according to claim 1, wherein the cold air inlet port and the cold air outlet port are defined in the same wall of the ice-making chamber and spaced a predetermined distance from each other.

6. The structure according to claim 1, wherein the cold air inlet port and the cold air outlet port are defined in different walls of the ice-making chamber.

7. The structure according to claim 1, wherein the cold air inlet port and the cold air outlet port are defined in a sidewall of the insulation case.

8. The structure according to claim 4, wherein the cold air exhaust port is provided in plurality.

9. The structure according to claim 4, wherein the cold air exhaust port is defined in a different wall of the ice-making chamber from a wall where the cold air inlet port is defined.

10. The structure according to claim 4, wherein the cold air exhaust port and the cold air outlet port are defined in opposite walls of the ice-making chamber.

11. The structure according to claim 4, wherein the cold air exhaust port and the cold air outlet port are defined in a diagonal location in the ice-making chamber.

12. The structure according to claim 1, wherein when the cold chamber door is closed, the cold air inlet port is connected to a cold air supply duct, which is disposed at a sidewall of a refrigerator body, to suck a freezing chamber cold air.

13. The structure according to claim 1, wherein when the cold chamber door is closed, the cold air outlet port is connected to cold air return duct, which is provided at the sidewall of the refrigerator body, to exhaust an ice-making chamber cold air.

14. The structure according to claim 1, wherein the ice-making unit has an ice maker for icing the supplied water by the ice-making cold air and taking out the pieces of ice, and an ice bank for keeping the pieces of ice taken out by the ice maker.

15. The structure according to claim 1, wherein the ice-making cold air guide unit has a bypass duct defined along an inner wall of the insulation case from the cold air inlet port to the ice-making chamber.

16. The structure according to claim 1, wherein the ice-making cold air guide unit has an ice-making air guide plate for the guiding.

17. A cold air guide structure of an ice-making chamber of a cold chamber door, the structure comprising:

the cold chamber door;
