  • Patent number: 9506686
    Abstract: Disclosed herein is a refrigerator in which a level difference between an inner cabinet and an outer cabinet is improved in coupling the inner cabinet with the outer cabinet by forming a corner of the inner cabinet located at a portion coupled with the outer cabinet to have a smaller radius. The refrigerator includes an inner cabinet in which a storage chamber is formed. The refrigerator also includes an outer cabinet coupled with an outside of the inner cabinet and configured to form an exterior. The refrigerator further includes an insulating material filling between the inner cabinet and the outer cabinet. The inner cabinet includes a storage portion configured to form the storage chamber. The inner cabinet also includes an edge portion configured to extend in a vertical direction toward the outside of the storage portion from a front surface edge of the storage portion and exposed to the outside.
