A multi-joint link hinge includes a hinge bracket, a plurality of links axially coupled to the hinge bracket, and a door bracket coupled to the plurality of links. The hinge bracket includes a base portion that defines a plurality of screw coupling holes at a vertical surface thereof, a plurality of side portions that extend from the base portion in a horizontal direction and are spaced apart from each other in a vertical direction, and a side surface portion that extends from the base portion in the vertical direction and defines a fixing groove. The plurality of links are coupled between the plurality of side portions along an axis that extends in the vertical direction. The multi-joint link hinge is used for a home appliance including refrigerators.

Provided is a refrigerator. The refrigerator includes: a cabinet including an outer case, an inner case disposed inside the outer case and defining a storage space, and an insulating material filled between the outer case and the inner case; a door pivotably connected to a front surface of the cabinet and selectively opening/closing a storage compartment; a shelf assembly including a shelf supporting arm fixed to a real surface of the inner case and a shelf connected to the shelf supporting arm so as to be slidably movable; and a withdrawal device connected to the door and withdrawing the shelf forward in accordance with pivoting of the door for opening the storage space. Here, the withdrawal device includes: a slide member held in a space between the outer case and the inner case; a link member including a front end portion connected to the door and a rear end portion connected to the slide member; and a connection member connecting the slide member and the shelf.

A pivot hinge bracket assembly for use with a pivot hinge for a reach-in type cool room refrigerator includes two mirror imaged main bracket portions and a pivot plate removably coupled to one of the main bracket portions. The main bracket portion includes an edge mounting flange extending to a rear mounting flange mounted to the cool room refrigerator door jamb. The edge mounting flange has a modified square mounting hole and pivot pin plate screw mounting holes. The rear mounting flange has two door screw mounting holes. The pivot plate includes a pivot plate mounting flange and a pivot pin. The pivot hinge bracket assembly also includes an optional removably coupled door stop.

Disclosed is an electronic device in which a multi joint hinge, which couples a door of the electronic device, is applied. The electronic device includes a main body having a storage space therein, a door configured to open and close the storage space, and a hinge coupled to the door and the main body in order to rotate the door with respect to the main body. The hinge includes a first bracket supported by the main body, a second bracket supported by the door, a link rotatably coupled between the first bracket and the second bracket, a resilient member provided on the link and having an elasticity; a cam provided on the second bracket and formed in a shape to contact with the resilient member, so that according to a rotation direction of the door, the elasticity of the resilient member acts as an opening force or a closing force of the door, and a cam stopper integrally formed with the second bracket to prevent the cam from being moved by the elasticity of the resilient member.

A refrigerator locking system is used to secure the doors of a refrigerator in closed or open positions. The system includes at least one anchor bar, a locking bracket, a door block and a refrigerator. The refrigerator includes a frame, at least one refrigerator door and a freezer door. The anchor bar is mounted to the frame in between the refrigerator door and the freezer door. The locking bracket is connected adjacent to the frame and is engaged with to the door block to secure the refrigerator door and the freezer door. The door block can be used to press the refrigerator door and the freezer door against the frame, keeping the refrigerator closed. Alternatively, the door block can be positioned in between the frame and both the refrigerator door and the freezer door to keep the refrigerator open.

A domestic refrigeration appliance includes a heat-insulated inner container delimiting a coolable interior for foodstuffs, a refrigeration device cooling the interior, a door leaf articulated by hinges for opening and closing the interior and an opening aid. At least one hinge is self-closing for automatically closing the door leaf up to a first opening angle. The opening aid includes an actuator and a tappet moving back and forth by the actuator between first and second positions. The opening aid enables the door leaf to be closed if the tappet is in the first position, to move the tappet from the first to the second position to push open the closed door leaf using the tappet up to a second opening angle smaller than the first opening angle, and to automatically move the tappet into the first position immediately or with a time delay after reaching the second position.

Door alarm systems, methods, and apparatus are disclosed. A door alarm system may monitor a door of a refrigeration device and detect a failed attempt at closing the door. In response to detecting the failed attempt, the door alarm system may generate a notification of the detected, failed attempt so that remedial action may be taken.

A vacuum adiabatic body according to the present invention includes at least one reinforcing frame which is installed along a corner of at least one of a first plate member and a second plate member constituting an inner wall and an outer wall of the vacuum adiabatic body and is provided as one body for reinforcing the strength, thereby being capable of reinforcing the strength of the vacuum adiabatic body which is applied to the three-dimensional structure.

A refrigerator door assembly includes a refrigerator door having a recess. An alignment mechanism includes a plate and a door hinge. The plate is fixedly attached to the door hinge and positioned at least partially within the recess of the refrigerator door. The refrigerator door is movably positionable between at least a first position and a second position relative to the plate to permit adjustment of a location of the refrigerator door relative to the door hinge.

A door opening and closing device for a refrigerator includes a door coupled to a main body, an opening and closing unit including a drive unit for generating rotational force by means of a motor and a door rotating mechanism for opening or closing the door, a device for measuring a back electromotive force generated from the motor, a power circuit connected for supplying power to the motor, a circuit for transmitting back electromotive force of the motor to the device, a control switch for selectively connecting the motor to the circuit or the power circuit, and a control unit for connecting the control switch to the power circuit when the motor is activated, and connecting the control switch to the circuit and opening or closing the door when the motor is deactivated, wherein the control unit closes the door when a predetermined back electromotive force is input to the device.
