Abstract

A body of a refrigerator may be deformed when the rigidity of the body is lowered due to a thickness of insulation being reduced to increase an internal capacity of the body. Deformation of the body of the refrigerator is reduced by improving rigidity of the body using a reinforcement structure. The refrigerator may include an electric apparatus box in which electric apparatus components for controlling an operation of the refrigerator are accommodated. Electric components may be disposed in a hinge cover which is disposed in the front of the refrigerator to improve spatial utility and a reinforcement plate formed of a steel material may be disposed in the electric apparatus box to prevent a fire from spreading.

First claim

What is claimed is:

1. A refrigerator comprising:
a body comprising an inner case in which a storage compartment is formed, an outer case that is coupled to an outside of the inner case and constitutes an exterior, and an insulating material disposed between the inner case and the outer case; and
a reinforcement member disposed between the inner case and the outer case of both sides of the body to prevent deformation of the body,
wherein
the reinforcement member is disposed at both sides of the body in a widthwise direction, and
a first portion of the reinforcement member is attached to the inner case and is connected to one end of a second portion of the reinforcement member which is bent away from a side surface of the inner case, and a third portion of the reinforcement member is attached to the inner case and is connected to another end of the second portion of the reinforcement member so that a gap including the insulating material is provided between the side surface of the inner case and the second portion of the reinforcement member.

2. The refrigerator of claim 1 , wherein the reinforcement member comprises a first reinforcement member disposed at an upper portion of both sides of the body and a second reinforcement member disposed at a lower portion of both sides of the body.

3. The refrigerator of claim 2 , wherein the reinforcement member is disposed to have a thickness of about 0.5 mm.

4. The refrigerator of claim 3 , wherein the reinforcement member is disposed to have a cross-section having an uneven shape, the cross-section having a larger thickness than a thickness of the reinforcement member and a smaller height than a distance between the inner case and the outer case.

5. A refrigerator comprising:
an inner case in which a storage compartment is formed;
an outer case that is coupled to an outside of the inner case and constitutes an exterior;
an insulating material disposed between the inner case and the outer case; and
a reinforcement member disposed between the inner case and the outer case to prevent deformation of the inner case and the outer case that occurs due to a difference in quantities of thermal contraction of the inner case and the outer case when the insulating material is foamed between the inner case and the outer case and then is solidified, the reinforcement member comprising:
a first portion attached to a side surface of one of the inner case and the outer case,
a second portion connected at one end to the first portion and bent away from the side surface of the one of the inner case and the outer case, and
a third portion attached to the one of the inner case and the outer case and connected to another end of the second portion so that a gap including the insulating material is provided between the side surface of the one of the inner case and the outer case and the second portion.

6. The refrigerator of claim 5 , wherein the reinforcement member is disposed to correspond to a direction in which the insulating material is foamed between the inner case and the outer case and flows.

7. The refrigerator of claim 6 , wherein the reinforcement member is disposed at both sides of the inner case in a widthwise direction and is attached to the inner case.

8. The refrigerator of claim 6 , wherein the reinforcement member is disposed at both sides of the outer case in a widthwise direction and is attached to the outer case.

9. The refrigerator of claim 6 , wherein the reinforcement member is disposed at both sides of the inner case in a lengthwise direction and is attached to the inner case.

10. The refrigerator of claim 6 , wherein the reinforcement member is disposed at both sides of the outer case in a lengthwise direction and is attached to the outer case.

11. A refrigerator comprising:
an inner case in which a storage compartment is formed;
an outer case that is coupled to an outside of the inner case and constitutes an exterior;
an insulating material disposed between the inner case and the outer case; and
a reinforcement member disposed between the inner case and the outer case at both sidewalls of the inner case to prevent deformation that occurs in a lateral direction of the inner case and the outer case due to a difference in quantities of thermal contraction between the inner case and the outer case when the insulating material is foamed and then is solidified, the reinforcement member comprising:
a first portion attached to a side surface of one of the inner case and the outer case,
a second portion connected at one end to the first portion and bent away from the side surface of the one of the inner case and the outer case, and
a third portion attached to the one of the inner case and the outer case and connected to another end of the second portion so that a gap including the insulating material is provided between the side surface of the one of the inner case and the outer case and the second portion.

12. The refrigerator of claim 11 , wherein the reinforcement member is disposed to correspond to a direction in which the insulating material is foamed between the inner case and the outer case and flows.

13. The refrigerator of claim 12 , wherein the reinforcement member is disposed at both sides of the inner case in a widthwise direction and is attached to the one of the inner case and the outer case using an adhesive.

14. The refrigerator of claim 12 , wherein the reinforcement member is disposed at both sides of the inner case in a lengthwise direction and is attached to the one of the inner case and the outer case using an adhesive.

15. The refrigerator of claim 11 , wherein the reinforcement member is disposed to have a thickness of about 0.5 mm and is formed of steel.

16. The refrigerator of claim 11 , wherein the reinforcement member is disposed to have a cross-section having an uneven shape, the cross-section having a larger thickness than a thickness of the reinforcement member and a smaller height than a distance between the inner case and the outer case.

17. The refrigerator of claim 11 , further comprising a reinforcement frame disposed at a front side of the refrigerator to supplement rigidity of the body, the reinforcement frame including at least one of an upper reinforcement frame coupled to an upper portion of the front side of the inner case, an intermediate reinforcement frame coupled to a central portion of the front side of the inner case, a lower reinforcement frame coupled to a lower portion of the front side of the inner case, and a side reinforcement frame coupled to a lower side portion of the front side of the inner case.

18. A refrigerator comprising:
an inner case in which a storage compartment is formed;
an outer case that is coupled to an outside of the inner case and constitutes an exterior;
an insulating material disposed between the inner case and the outer case; and
a reinforcement member disposed in the insulating material between the inner case and the outer case at a side of the body, and being attached to one of the inner case and the outer case, the reinforcement member comprising:
a first portion attached to a side surface of one of the inner case and the outer case,
a second portion connected at one end to the first portion and bent away from the side surface of the one of the inner case and the outer case, and
a third portion attached to the one of the inner case and the outer case and connected to another end of the second portion so that a gap including the insulating material is provided between the side surface of the one of the inner case and the
