摘要： Provided is a refrigerator which allows a pivoting bar to pivot to seal a gap between a pair of doors regardless of whether the door at which the pivoting bar is not installed between the pair of doors is open or closed. The refrigerator includes a guide device which induces the pivoting bar to pivot. Here, the guide device includes a rack that is moved forward and backward linearly depending on opening and closing of the second door and includes a second magnet built therein, a pinion gear engaged with the rack and pivoting when the rack is moved linearly, and a guide unit which includes a guide groove guiding a guide protrusion and is engaged with the pinion gear to move linearly in a direction opposite to that of the rack to allow the pivoting bar to pivot when the pinion gear pivots.

摘要： Disclosed herein are a driving unit and a robot cleaner having the same. The robot cleaner has a configuration in which an elastic member is supported so that an angle formed between the elastic member and a rotation shaft of the driving unit is provided in a predetermined range to offset a decrease in an elastic force generated while the robot cleaner is driving on a surface having steps and a driving wheel protrudes downward from the robot cleaner. Accordingly, there is the effect where a traction force is maintained at a predetermined level for maintaining the driving performance of the robot cleaner even while the robot cleaner is driving and the driving wheel is lowered to decrease the elastic force of the elastic member.

摘要： Disclosed herein is a refrigerator that has an improved structure to facilitate assembling of a door and a main body which are separable from each other. The refrigerator includes a main body that forms an exterior appearance, a storage compartment that is provided inside the main body, a door that is rotatably coupled to the main body so as to open and close an open front surface of the storage compartment, and a hinge bracket that connects the main body and the door. Here, the hinge bracket includes a first bracket that is coupled to the main body and a second bracket that is coupled to the door and detachably coupled to the first bracket.

摘要： Disclosed herein is a cleaning robot capable of allowing a driving apparatus to move along a cleaning apparatus when the cleaning apparatus is separated from the driving apparatus, and a controlling method thereof. In addition, a cleaning robot having a driving apparatus capable of storing a position from which a cleaning apparatus is separated when the cleaning apparatus is separated from the driving apparatus, and capable of moving to the stored position when the cleaning apparatus is mounted to the driving apparatus, and a controlling method thereof. The cleaning robot includes a driving apparatus provided with a mounting groove configured to allow a cleaning apparatus to be removably mounted, and the cleaning apparatus removably mounted to the mounting groove. When the cleaning apparatus is separated from the mounting groove, the driving apparatus stores a position of the driving apparatus upon the separation of the cleaning apparatus and when the cleaning apparatus is mounted to the mounting groove, the driving apparatus moves to the stored position.

摘要： The present disclosure includes a main body, a cleaning tool assembly connected to the main body to be movable in at least one axial direction, a handle part connected to the main body and configured to receive an applied force of a user, a detection part provided in the handle part and configured to detect a magnitude and a direction of the force applied to the handle part, and a control part configured to control the movement direction of the cleaning tool assembly based on the detected direction of the force and to control the movement distance of the cleaning tool assembly based on the detected magnitude of the force. In this way, the steering performance may be improved by reducing a horizontal load felt by a user when the user holds and moves the handle of the cleaner, fatigue felt when performing the cleaning operation may be removed by removing a vertical load applied by the handle, and convenience may be improved.
