The present invention provides a refrigerator, comprising a cabinet, a door and a hinge body. A guide block is fixedly provided on the door, a positioning shaft and a guiding shaft are provided on the hinge body, and a positioning groove and a guiding groove are provided on the guide block; the door of the refrigerator according to the present invention may be moved by a distance in a direction away from a pivoting side when being opened, thereby avoiding inconvenience of opening the door due to the protrusion of the side wall of the door.

The present invention provides a refrigerator, comprising a cabinet, a door and a hinge body, wherein a positioning shaft and a guiding shaft are provided on the hinge body, and a positioning groove and a guiding groove are provided on the door; the door of the refrigerator according to the present invention may be moved by a distance in a direction away from a pivoting side when being opened, thereby avoiding inconvenience of opening the door due to the protrusion of the side wall of the door.

The present invention provides a refrigerator, comprising a refrigerator body and a door body. A hinge body is disposed on the refrigerator body. A first hinge shaft and a second hinge shaft are disposed on the hinge body. A first guide groove and a second guide groove are formed in the door body. The first hinge shaft is located in the first guide groove and the second hinge shaft is located in the second guide groove. During opening of the door body, the first guide groove moves relative to the first hinge shaft and the second guide groove moves relative to the second hinge shaft, the first hinge shaft applies an acting force to the first guide groove to drive the end, away from the first guide groove, of the second guide groove to approach the second hinge shaft, so that the door body is displaced in a horizontal direction.

The present invention provides a refrigerator, comprising a refrigerator body and a door body. A hinge body is disposed on the refrigerator body. A first hinge shaft and a second hinge shaft are disposed on the hinge body. A first guide groove and a second guide groove are formed in the door body. The first hinge shaft is located in the first guide groove and the second hinge shaft is located in the second guide groove. During opening of the door body, the first guide groove moves relative to the first hinge shaft and the second guide groove moves relative to the second hinge shaft, the first hinge shaft applies an acting force to the first guide groove to drive the end, away from the first guide groove, of the second guide groove to approach the second hinge shaft, so that the door body is displaced in a horizontal direction.

The present invention provides a refrigerator, comprising a cabinet, a door and a hinge body. A guide block is provided on the door, a rotation shaft is provided on the hinge body, and rotation shaft grooves are provided on the guide block. With the structure of the hinge body, the gravity of the door and the friction force may be shared onto the first and second plate bodies of the hinge body, thereby reducing abrasion and prolonging the service life of the door of the refrigerator.

A drive system for a garage door with an electric drive controlled by a control unit, by means of which drive the garage door is displaceable between a closed position and an open position. Furthermore, an operating unit is provided, into which input commands for controlling the garage door can be entered. An input command designed as a delivery input command is provided. When a delivery input command is entered, the operating unit causes a partial opening of the garage door for a preset time. After expiry of this time, the operating unit causes the garage door to automatically move to the closed position.
