Refrigerator including multiple storage compartments

A refrigerator, comprising:

• a cabinet;
• a first storage area within the cabinet;
• a first door that has a front surface, a rear surface, an upper surface, a lower surface, a first side surface, and a second side surface, the first door being rotatably connected to the cabinet, wherein when the first door is oriented in a closed position, the rear surface of the first door contacts a front surface of the cabinet, the first door including:
• a pair of door dikes protruding rearward, respectively, from both side edge portions of the rear surface of the first door, each of the pair of door dikes extending in a vertical direction, the pair of door dikes defining at least a first portion of a second storage area within the first door in which a plurality of vertically spaced shelves are arranged,
• an access opening defined between the pair of door dikes and configured to enable access to the second storage area,
• a plurality of first coupling parts disposed on inner side surfaces of the pair of door dikes, and
• a first stepped portion defined as part of the upper surface of the first door, the first stepped portion being recessed downward from an uppermost portion of the upper surface of the first door;
• a second door that has a front surface, a rear surface, an upper surface, a lower surface, a first side surface, and a second side surface, the second door being rotatably connected to the first door, wherein when the second door is oriented in a closed position, the rear surface of the second door contacts the front surface of the first door to close the access opening, wherein the second door includes a second stepped portion defined as part of the upper surface of the second door, the second stepped portion being recessed downward from an uppermost portion of the upper surface of the second door;
• a hinge assembly including:
• a first hinge that rotatably couples the first stepped portion to an upper surface of the cabinet, and
• a second hinge that rotatably couples the second stepped portion to the first stepped portion, wherein a rotation direction of the first door for opening the first storage area is the same as a rotation direction of the second door for opening the access opening;
• a frame coupled to the pair of door dikes and defining at least a second portion of the second storage area that is different from the first portion of the second storage area defined by the pair of door dikes, the frame defining at least the second portion of the second storage area by covering at least a portion of side and rear surfaces of the second storage area such that, when the first door is oriented in the closed position, the frame provides at least a partial barrier between the second storage area and the first storage area, the frame including:
• a pair of side surfaces that extend in the vertical direction and whose front ends are in contact with the rear ends of the pair of the door dikes,
• a plurality of horizontal plates connecting the pair of the side surfaces, the plurality of horizontal plates being vertically spaced apart from each other, and
• extension parts vertically extending from both side ends of each of the horizontal plates and protruding forward from the front ends of the pair of side surfaces,
• a basket fixed to inner surfaces of the pair of side surfaces of the frame, wherein a portion of both side walls of the basket further protrude forward from the front ends of the pair of side surfaces of the frame;
• and
• a plurality of second coupling parts provided at outer surfaces of the extension parts and the side walls of the basket, and configured to be detachably coupled to the plurality of first coupling parts,
• wherein the extension parts further include upper extension parts on the side ends of an upper one of the plurality of horizontal plates and lower extension parts on the side ends of a lower one of the plurality of horizontal plates, the upper extension parts being vertically aligned and spaced apart from the lower extension parts, respectively, to thereby define respective openings therebetween.
