Abstract

Disclosed is a refrigerator. The refrigerator includes a cabinet ( 10 ) configured to define a first storage region in which food is stored, a door ( 20 ) rotatably connected to a first rotating shaft via a first hinge member ( 40 ) to open or close the first storage region, the first rotating shaft being located at the front of the cabinet ( 10 ), a gasket provided at the door ( 20 ) and a container ( 100 ) configured to define a second storage region, the second storage region being received in the first storage region, the container ( 100 ) being rotatably connected to a second rotating shaft via a second hinge member ( 200 ), the second rotating shaft being located at the door ( 20 ).

First claim

The invention claimed is:

1. A refrigerator comprising:
a cabinet;
a storage compartment provided in the cabinet and configured to store food therein;
a container provided to be rotatable relative to the cabinet and configured to open and close the storage compartment to selectively provide access to items in the storage compartment, the container comprising an opening formed in a center thereof;
a door rotatably provided on the container and configured to be rotatable relative to the container and to the cabinet, and to open and close the opening in the container; and
a fastening device disposed at the door and configured to selectively couple the door to the container and to release the door from the container, the fastening device being configured to couple the door to the container to allow the door and the container to rotate together and to release the door from the container to allow the door to rotate relative to the container,
wherein the container comprises a frame cover and a frame provided inside the frame cover,
wherein the frame comprises:
horizontal portions respectively forming an upper side and a lower side of the frame;
vertical portions provided perpendicular to the horizontal portions and respectively forming a left side and a right side of the frame; and
an integrated horizontal and vertical portion that is configured to couple one of the horizontal portions and one of the vertical portions to each other,
wherein the integrated horizontal and vertical portion comprises a first coupling portion that extends horizontally, and a second coupling portion arranged perpendicular to the first coupling portion,
wherein the vertical portions and the horizontal portions of the frame comprise hollow regions, respectively, and the first coupling portion and the second coupling portion of the integrated horizontal and vertical portion are inserted into and coupled to the hollow regions of the one of the horizontal portions and the one of the vertical portions of the frame,
wherein the one of the horizontal portions and the one of the vertical portions each have a cross section that forms a closed curve around the corresponding hollow region, and
wherein each of the first coupling portion and the second coupling portion has a shape corresponding to the closed curve.

2. The refrigerator according to claim 1 , wherein the integrated horizontal and vertical portion comprises a curved portion between the second coupling portion and the first coupling portion that comprises a bent hollow metal frame.

3. The refrigerator according to claim 1 , wherein the integrated horizontal and vertical portion further comprises a curved portion between the second coupling portion and the first coupling portion that forms a vertex of the frame of the container.

4. The refrigerator according to claim 1 , wherein the hollow regions of the one of the horizontal portions and the one of the vertical portions of the frame comprise:
a first opening at the one of the horizontal portions into which the first coupling portion of the integrated horizontal and vertical portion is configured to be inserted; and
a second opening at the one of the vertical portions into which the second coupling portion of the integrated horizontal and vertical portion is configured to be inserted.

5. The refrigerator according to claim 4 , wherein the first opening is formed at an end of the one of the horizontal portions and is configured to receive the first coupling portion of the integrated horizontal and vertical portion along a longitudinal direction of the one of the horizontal portions; and
wherein the second opening is formed at an end of the one of the vertical portions and configured to receive the second coupling portion of the integrated horizontal and vertical portion along a longitudinal direction of the one of the vertical portions.

6. The refrigerator according to claim 1 , wherein the integrated horizontal and vertical portion has a solid interior.

7. The refrigerator according to claim 6 , wherein the solid interior of the integrated horizontal and vertical portion is formed at least in the first coupling portion and in the second coupling portion of the integrated horizontal and vertical portion.

8. The refrigerator according to claim 1 , wherein the horizontal portions of the frame comprise a first member forming the lower side of the frame and a third member forming the upper side of the frame, and
wherein the vertical portions of the frame comprise a second member forming the left side of the frame and a fourth member forming the right side of the frame.

9. The refrigerator according to claim 8 , wherein the first member, the second member, the third member, and the fourth member collectively form four respective sides of the frame.

10. The refrigerator according to claim 1 , wherein at least one of the hollow regions of the horizontal portions and the vertical portions has a polygonal cross-sectional shape.

11. The refrigerator according to claim 1 , wherein the first coupling portion and the second coupling portion of the integrated horizontal and vertical portion each have an angled cross-sectional shape in a polygonal shape.

12. The refrigerator according to claim 1 , wherein a horizontal distance from the one of the vertical portions to an end of the first coupling portion of the integrated horizontal and vertical portion is equal to or less than a horizontal distance from the one of the vertical portions to a center of the one of the horizontal portions.

13. The refrigerator according to claim 1 , wherein a vertical distance from the one of the horizontal portions to an end of the second coupling portion of the integrated horizontal and vertical portion is equal to or less than a vertical distance from the one of the horizontal portions to a center of the one of the vertical portions.

14. The refrigerator according to claim 1 , wherein the frame is formed of a metal material and is manufactured by a bending process.

15. The refrigerator according to claim 1 , wherein the frame comprises a curved portion having a predetermined curvature and that forms a vertex of the frame.

16. The refrigerator according to claim 1 , further comprising a basket provided to extend across the opening of the container, with opposite ends of the basket being fixed.

17. The refrigerator according to claim 1 , wherein the frame cover of the container surrounds the frame of the container and prevents the frame from being exposed to an outside of the refrigerator.

18. The refrigerator according to claim 1 , wherein the frame and the frame cover of the container are formed of different materials, and
wherein the frame is formed of a first material having a higher strength than a second material of the frame cover.

19. The refrigerator according to claim 1 , wherein the first coupling portion is inserted into the hollow region of the one of the horizontal portions and surrounded by the one of the horizontal portions, and
wherein the second coupling portion is inserted into the hollow region of the one of the vertical portions and surrounded by the one of the vertical portions.
