Abstract: Disclosed is a refrigerator capable of minimizing generation of undercuts when manufacturing components of an inner case by injection molding. The refrigerator includes an inner case forming a storage compartment, and comprising a plurality of plates formed by injection molding; an outer case coupled to an outside of the inner case to form an external appearance; and an insulation disposed between the inner case and the outer case. A rear plate corresponding to one of the plates comprises: a drain hole formed through the rear plate to discharge water inside the inner case to the outside of the inner case; an inclined surface inclined downward toward the drain hole to allow water inside the inner case to flow to the drain hole; and an undercut prevention surface disposed below and spaced apart from the inclined surface, and forming a portion of an outer surface of the rear plate.

Abstract: A refrigerator includes a main body including an inner case including plates each formed by injection molding, an outer case coupled to the inner case. At least one of plates include a front flange forming a front surface of the at least one plate and coupled to the outer case, the outer case includes an insertion groove into which the front flange is inserted. The front flange includes locking ribs arranged to prevent the front flange from moving in a direction opposite to an insertion direction of the front flange based on inserting the front flange into the insertion groove, the locking ribs are injection molded integrally with the at least one plate and protrude from the front flange so as to be locked on the outer case. The locking ribs are spaced apart from each other along a longitudinal direction of the front flange.
