Abstract:
A refrigerator includes a cabinet, a main-door, the main-door, a sub-door, a restraint device that protrudes from a rear surface of the sub-door, a latch device located at the main-door and configured to selectively restrict movement of the restraint device, and an operation device located at the sub-door and configured to release the restraint device from the latch device. The latch device includes a latch configured to restrict movement of the restraint device from the latch based on rotation of the latch, a stopper configured to engage a side of the latch and limit movement of the latch, a pusher configured to push the stopper to cause the stopper to rotate, and an elastic member connected to the latch and to the stopper. The latch is configured to, based on rotation of the stopper, rotate and release restraint between the latch and the stopper.

Claim (Index 1):
A refrigerator comprising:\n a cabinet that defines a storage space; a main-door configured to open and close at least a portion of the storage space, the main-door defining a door storage space; a sub-door configured to open and close at least a portion of the door storage space; a restraint device that protrudes from a rear surface of the sub-door; a latch device that is located at the main-door and that is configured to receive the restraint device and selectively restrict movement of the restraint device from the latch device; and an operation device located at the sub-door and configured to, based on operation by a user, release the restraint device from the latch device, wherein the latch device comprises:\n a latch configured to rotate about a first rotation shaft and restrict movement of the restraint device from the latch based on rotation of the latch about the first rotation shaft, \n a stopper that extends from a second rotation shaft located vertically below the first rotation shaft to an upper side of the latch, the stopper being configured to, based on rotation of the stopper about the second rotation shaft, engage a side of the latch and limit movement of the latch, \n a pusher located at an upper side of the latch and configured to, based on operation of the operation device, push the stopper to cause the stopper to rotate about the second rotation shaft, and \n an elastic member connected to the latch and to the stopper, and configured to provide force to allow the latch and the stopper to contact each other, and \n wherein the latch is configured to, based on the rotation of the stopper about the second rotation shaft in a first direction, rotate about the first rotation shaft in the first direction and release restraint between the latch and the stopper.
