    Abstract: 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.

    Abstract: A refrigerator includes a cabinet defining a storage chamber, a drawer door configured to be inserted into and withdrawn out of the storage chamber, a driving device provided at the door part, an elevation device provided at the drawer part and having a scissors lift assembly, and a connecting assembly that couples the driving device to the scissors lift assembly to transfer driving force from the driving device to the scissors lift assembly. The elevation device is configured, based on being uncoupled from the connecting assembly, to be separable from the drawer part, and the elevation device includes a restricting unit configured to restrict the scissors lift assembly from unfolding when the elevation device is separated from the drawer part. The drawer door includes a drawer part and a door part that is configured to, based on the drawer door being inserted into the storage chamber, close the storage chamber.
