20130264928REFRIGERATOR - In a refrigerator including a sliding door configured to open and close a storage chamber, a storage basket provided on a rear portion of the sliding door, and a support frame configured to support the sliding door and the storage basket, sidewalls of the storage basket may be formed so as to protrude outwardly except a lower portion in which the support frame is disposed between an inner case and the sidewalls, thereby increasing a storage space of the storage basket. In addition, a front protrusion, an auxiliary protrusion, and a rear protrusion are formed in an upper portion of the storage basket, and therefore a relative position of an auxiliary basket to the storage basket may be limited, and the auxiliary basket may be drawn into and out in conjunction with drawn-in and-out movements of the storage basket.10-10-2013
20130264930SEMI-AUTO CLOSING APPARATUS AND REFRIGERATOR HAVING THE SAME - A refrigerator which improves the structure of an auto closing apparatus, increases the sealing ability of a door, and omits mounting of a separate spring. The refrigerator includes at least one door opening and closing at least one storage chamber provided in a main body, at least one upper hinge module including a body part and an extension part rotatably coupled to the at least one door, at least one lower hinge module, a door cap installed on an upper portion of the at least one door and including a hinge receiving part, an auto close lever coupled to the door cap and has elasticity to transmit elastic force to the door, and a cam member including a cam surface contacting the auto close lever so that the auto close lever accumulates elastic force and then transmits the elastic force to the door when the door is closed.10-10-2013
20130293080REFRIGERATOR AND METHOD OF MANUFACTURING DOOR THEREOF - Disclosed herein is a door of a refrigerator in which a vacuum insulation is positioned in the inner core of the door to be spaced apart from the top face, bottom face, front face, rear face and both lateral faces of the door, and a foam insulation is uniformly disposed in the remaining space in the door.11-07-2013
20150159934REFRIGERATOR - A rear plate of a refrigerator includes a base section formed at the outside of the rear plate while being flat, and a formed section formed to protrude from the base section toward the inner case through a foaming process. Outer equipment is installed at the formed section, to be disposed more inside than the base section and, as such, it is possible to protect the outer equipment from external impact. In addition, it is possible to achieve an improvement in rear appearance design of the refrigerator and an enhancement in space utility of the refrigerator.06-11-2015
20150260443REFRIGERATOR - Provided is a refrigerator having only a second door opened/closed or having both of a first door and a second door opened/closed using one handing by allowing a latch device to fix the second door to the first door or release the second door from being fixed to the first door. The refrigerator includes a main body having a storage compartment, a first door that is rotatably disposed in front of the main body and has an opening formed therein, a second door that is rotatably disposed in front of the first door to open/close the opening, a handle coupled to a front side of the second door to open/close the first door and the second door, and a latch device allowing the second door to be fixed and released to/from the first door.09-17-2015
20150260445REFRIGERATOR - A refrigerator includes a main body having a storage compartment, a first door that is rotatably disposed in front of the main body and has an opening, a door guard disposed in the opening, a second door that is rotatably disposed in front of the first door, opens/closes the opening, and is rotated in the same direction as the first door, first hinges coupling the first door rotatably to the main body, and second hinges coupling the second door rotatably to the first door, elastic levers coupled to the first door applying an elastic force in a direction in which the first door is closed, and a first stopping member coupled to the first door to limit an angle at which the first door is opened and a second stopping member coupled to the second door to limit an angle at which the second door is opened.09-17-2015
20150260447REFRIGERATOR - A refrigerator having a structure in which, when a first door or a second door is opened, a lamp installed at sidewalls of an opening in the first door emits light so that food stored in a door guard disposed in the opening can be illuminated. The refrigerator includes a main body having a storage compartment; a first door that is rotatably disposed in front of the main body and opens/closes the storage compartment, and has an opening formed therein, where at least one door guard is disposed in the opening; a second door that is rotatably disposed in front of the first door, opens/closes the opening, and is rotated in the same direction as the first door; and a lamp installed at the sidewalls of the opening.09-17-2015
