An elevation device for a refrigerator drawer includes a lower frame, an upper frame, and a lifting assembly. The lifting assembly includes: a pair of first rods having a first end rotatably coupled to the lower frame and a second end that translates along the upper frame; and a pair of second rods having a first end rotatably coupled to the upper frame and a second end that translates along the lower frame. The second rod is rotatably coupled to and crosses the first rod. The first or second rod is connected to a driving device via the first end of the first or second rod, with the driving device disposed outside the upper frame and the lower frame. The first and second rods are configured to, based on power from the driving device, rotate about their respective first ends to elevate the upper frame relative to the lower frame.

A refrigerator is provided. The refrigerator includes a storeroom lifted when the storeroom is pulled out and giving a degree of freedom to a lifting method. The refrigerator includes a main body, a door arranged to be pulled out from the main body, a storeroom arranged to be pulled out from the main body along with the door, and a lift device arranged to lift or lower the storeroom in connection with pulling-out or pushing-in of the door, wherein the lift device includes a guide including a portion sloping upward or downward in a pull-out direction of the storeroom, and a guidee guided by the guide so that the storeroom is lifted when the guidee is moved along the guide.

A refrigerator includes a cabinet having a storage space; a door including a door unit to open or close the storage space and a drawer unit to provide a receiving space; rails to connect the door and the cabinet to through which the door is drawn in or out of the cabinet; a driving device disposed at the door unit to provide power; and an elevation device disposed at the drawer unit and connected with the driving device to move up or down at the drawer unit. The driving device includes: a motor assembly; a screw unit including a screw to be rotated by the motor assembly and a screw holder to move up or down along the screw; and a lever to connect the screw holder and the elevation device and rotate when the screw holder moves up or down. The motor assembly includes: a driving motor; and a power transmission unit to transmit power from the motor to the screw unit, and the screw is disposed to be inclined with respect to a vertical line passing in a top-bottom direction of the refrigerator.

A refrigerator includes a cabinet defining a storage chamber, a drawer door, a motor assembly provided at the storage chamber and configured to provide a driving force that moves the drawer door relative to the storage chamber, and a rack gear assembly provided at the drawer door and having an extendable rack gear. The rack gear includes a fixed rack fixed to the drawer door and a moving rack slidably coupled to the fixed rack. The drawer door includes a drawer part that defines an upwardly open storage space, and a door part that is configured to, based on the drawer door being inserted into the storage chamber, close the storage chamber.

A refrigerator includes: a cabinet; an upper door; a lower door that is a drawer type door; a draw-out rail that connects the lower door to a storage space in the cabinet and that guides insertion and withdrawal of the lower door in a front-rear direction; an elevation assembly that is located in the lower door, that elevates an object stored in the lower door in a state in which the lower door is withdrawn, and that elevates the object relative to the lower door; and a door restriction device configured to selectively restrict an opening movement of the upper door based on whether the lower door is opened or closed. The door restriction device is configured to restrict the opening movement of the upper door based on the lower door being opened, and to allow the opening movement of the upper door based on the lower door being closed.

The first or second rod is connected to a driving device via the first end of the first or second rod, with the driving device disposed outside the upper frame and the lower frame. The first and second rods are configured to, based on power from the driving device, rotate about their respective first ends to elevate the upper frame relative to the lower frame.

To configure existing drawers as evacuable drawers of a vacuum drawer device, a cover for installation in the drawer body can be used. The cover evacuates at the drawer interior with an evacuation system, so that the interior is evacuated when the drawer is closed and ventilated before the drawer is opened. The cover is airtight, is profiled in such that evacuation with a controller, a pump and a valve are fixedly integrated in at least one recess in the cover and the cover has at least one air channel leading into the inside of the cover or, respectively, into the at least one recess, with the air channel operatively connected to the evacuation system such that when the cover is placed onto the drawer, air from the interior can be pumped out of the interior, the inside of the cover interior or, respectively, the at least one recess through the air duct.
