The flow path part 330 may include a plurality of air discharge holes 333 through which cold air is discharged.

[0117] As illustrated in FIG. 27, the rear panel 320 and the flow path part 330 may be integrally formed. That is, the flow path 330 may be joined to the inner case 11 to form the flow path 331 for guiding cold air.

[0118] The air duct 300 may include an air duct cover 340 detachably attached to the inner case 11. The air duct cover 340, which is visible to a user when the user opens the door 30 (see FIG. 1), may have various designs.

[0119] The air duct cover 340 may include a plurality of air discharge holes 341. The plurality of air discharge holes 341 may be formed at positions corresponding to the plurality of air discharge holes 333 formed on the flow path part 330. Therefore, the cold air guided by the flow paths 321 and 331 may be discharged into the refrigerating compartment 21 (see FIG. 1) through the plurality of air discharge holes 333 formed on the flow path part 330 and the plurality of air discharge holes 341 formed on the air duct cover 340.

[0120] The air duct cover 340 may be detachably attached to the inner case 11 by the screws S. The air duct cover 340 attached to the inner case 11 may be replaced, independent of any other parts, thereby allowing the user to vary the design of the air duct cover 340.

[0121] In order to detachably attach the air duct cover 340 to the inner case 11, the inner case 11 may include an assembly groove 12. An upper portion of the air duct cover 340 may be inserted into and secured via the assembly groove 12.

[0122] In order to detachably attach the air duct cover 340 to the inner case 11, the inner case 11 may include a plurality of fastening holes 13 into which the air duct cover 340 is detachably joined by the screws S. The air duct cover 340 may include a plurality of fastening holes 343 detachably attached to the inner case 11 by the screws S. To distinguish the plurality of fastening holes 343 formed on the air duct cover 340 from the plurality of fastening holes 13 formed on the inner case 11, the fastening holes 343 formed on the air duct cover 340 may be referred to as first fastening holes, and the fastening holes 13 formed on the inner case 11 may be referred to as second fastening holes.

[0123] To detachably attach the air duct cover 340 to the inner case 11, an upper portion of the air duct cover 340 may be inserted into the assembly groove 12 (see FIG. 30) of the inner case 11 as illustrated in FIG. 28. The upper portion of the air duct cover 340 is inserted into the assembly groove 12 of the inner case 11, and the air duct cover 340 may be attached to the inner case 11 by the screws S as illustrated in FIG. 29. When the air duct cover 340 is separated from the inner case 11, the screws S are removed to separate a lower portion of the air duct cover 340 from the inner case 11 and then the upper portion of the air duct cover 340 is removed from the assembly groove 12, so that the air duct cover 340 may be detached from the inner case 11.

[0124] Although certain embodiments have been described in the description of the refrigerator with reference to the accompanying drawings, various modifications and changes are possible by those skilled in the art, and these modifications and changes should be construed as being included in the scope of rights of the present disclosure.
