an upper restriction rib that is disposed at the upper support end, the upper restriction rib protruding downward and being inserted into the insertion portion to thereby restrict the upper end of the panel assembly from being detached from the upper cap decor.

4. The refrigerator according to claim 3 ,

wherein the insertion protrusion is provided in plurality, and

wherein the panel assembly further comprises:

a fixing bracket disposed at the rear surface of the panel assembly and disposed below the panel bracket, and

the plurality of insertion protrusions disposed on the fixing bracket and arranged at a same height along the fixing bracket.

5. The refrigerator according to claim 1 , wherein the insertion protrusion is in contact with a bottom surface of the recessed space of the handle.

6. The refrigerator according to claim 1 , wherein a top surface of the insertion protrusion is inclined with respect to a protruding direction of the insertion protrusion away from the panel such that a thickness of the insertion protrusion decreases in the protruding direction, and

wherein a bottom surface of the insertion protrusion is disposed vertically below a bottom surface of the recessed space of the handle.

7. The refrigerator according to claim 1 , wherein the panel assembly further comprises a lower bracket that is disposed at a rear surface of the panel and extends along a lower end of the panel, the lower bracket being coupled to the lower cap decor.

8. The refrigerator according to claim 1 , wherein the handle defines a restriction member insertion hole in the recessed space of the handle,

wherein the insertion protrusion defines a through-hole that faces the restriction member insertion hole and is aligned with at least a portion of the restriction member insertion hole, and

wherein the restriction member is inserted into the restriction member insertion hole and the through-hole.

9. The refrigerator according to claim 1 , wherein the restriction portion comprises:

a first restriction portion configured to interfere with the restriction member; and

a plurality of second restriction portions spaced apart from each other and disposed at left and right sides of the first restriction portion, the plurality of second restriction portions being configured to interfere with side surfaces of the insertion protrusion, and

wherein the restriction member passes between the plurality of second restriction portions.

10. The refrigerator according to claim 1 , wherein the handle defines a restriction member insertion hole at an inner surface of the recessed space of the handle, and

wherein the restriction member comprises:

a cap that covers the restriction member insertion hole; and

a body portion that extends from a bottom surface of the cap and passes through the inner surface of the recessed space, the body portion being configured to interfere with the insertion protrusion.

11. The refrigerator according to claim 10 , wherein the body portion comprises a restriction member support portion curved toward a circumference of the restriction member insertion hole and configured to interfere with the circumference of the restriction member insertion hole to thereby restrict the restriction member from being separated from the restriction member insertion hole.

12. The refrigerator according to claim 1 ,

wherein the panel assembly further comprises a restriction member that passes through the lower cap decor and is coupled to a lower end of the panel assembly.

13. The refrigerator according to claim 1 , wherein the panel assembly further comprises:

an upper bracket that is disposed at a rear surface of the panel, that faces the upper cap decor, and that extends along an upper portion of the panel, the upper bracket comprising the insertion protrusion that is inserted into the upper cap decor; and

a lower bracket that is disposed at the rear surface of the panel, that faces the lower cap decor, and that extends along a lower portion of the panel, the lower bracket being configured to couple to the lower cap decor.

14. The refrigerator according to claim 13 , wherein the lower bracket comprises:

a lower adhesion portion that is attached to the rear surface of the panel and extends along the rear surface of the panel; and

a restriction protrusion that protrudes rearward from the lower adhesion portion and is inserted into a front surface of the lower cap decor.

15. The refrigerator according to claim 14 , wherein the lower cap decor defines:

a front opening at the front surface of the lower cap decor, the front opening receiving the restriction protrusion;
