Claims15
A damper apparatus in combination with a refrigerator, comprising:
- a first duct opening section that introduces cooling air in a first specified storage section within the refrigerator;
- a second duct opening section that introduces cooling air to the front side of said specified storage section through a circular duct;
- a single damper open/close plate with two faces, each of the faces facing each of the first and second duct opening sections, which controllably open and close the first and second duct opening sections, respectively, wherein the refrigerator damper apparatus controls to open and close the damper open/close plate in three modes including an open-open mode, an open-close mode and a close-open mode, wherein the refrigerator damper apparatus is operated in association with an opening movement of the refrigerator access door to close the first opening section and open the second opening section.
A refrigerator comprising:
- a forced cooling air circulation duct;
- a first opening section that introduces cooling air in first specified storage section within the refrigerator;
- a second opening section that is operational in association with an opening movement of a refrigerator access door to introduce cooling air in a second specified storage section within the refrigerator;
- and
- a refrigerator damper apparatus having a single damper open/close plate with two faces, each of the faces facing each of the first and second opening sections, that controllably open and close the first and second opening sections, respectively, wherein the refrigerator damper apparatus controls to open and close the damper open/close plate in three modes including an open-open mode, an open-close mode and a close-open mode, wherein the refrigerator damper apparatus is operated in association with an opening movement of the refrigerator access door to close the first opening section and open the second opening section.
