Refrigerator

A refrigerator comprising:

• a cabinet that defines a storage space;
• and
• a door configured to open and close at least a portion of the storage space, the door comprising:
• a frame that includes (i) an upper frame portion that protrudes toward a front of the refrigerator, the upper frame portion including a coupling protrusion that extends downward and (ii) a lower frame portion that protrudes toward the front of the refrigerator, the lower frame portion defining a coupling hole configured to receive a fastening member, and
• a panel that is configured to be detachably coupled to the frame and that defines an outer appearance of the door, the panel being made from metal and including (i) an upper extension part that is bent rearward to extend in a rearward direction and (ii) a lower extension part that is bent rearward to extend in the rearward direction,
• wherein the upper extension part of the panel defines one or more openings configured to receive the coupling protrusion to thereby couple the upper extension part to the upper frame portion, the upper extension part further including (i) a first upper extension part that extends a first upper extension length in the rearward direction and (ii) a second upper extension part that extends a second upper extension length in the rearward direction, wherein the second upper extension length is greater than the first upper extension length, and the one or more opening of the upper extension part being defined at the second upper extension part,
• wherein the lower extension part defines one or more openings configured to receive the fastening member that is inserted sequentially into the coupling hole and then into the one or more openings to thereby couple the lower extension part to the lower frame portion, the lower extension part further including (i) a first lower extension part having a first lower extension length in the rearward direction and (ii) a second lower extension part having a second lower extension length in the rearward direction, wherein the second lower extension length is greater than the first lower extension length, and the one or more opening of the lower extension part are defined at the second lower extension part, and
• wherein the panel is configured, based on the coupling protrusion being inserted into the one or more openings of the second upper extension part, to be subsequently rotated toward the frame such that the one or more openings of the second lower extension part become aligned with the coupling hole of the lower frame portion to receive the sequentially inserted fastening member.
