Abstract:
A refrigerator (10) and a drawer assembly (200) thereof, the drawer assembly (200) comprising: a support (210), which has two vertical plates (212) arranged oppsite each other; a drawer (220), which is connected between the two vertical plates (212) in a sliding manner; and an upper cover (230), which is buckled on the drawer (220) for sealing a top opening of the drawer (220). Two sides of the upper cover (230) are respectively provided with a pre-tightening structure between the vertical plates (212), wherein each pre-tightening structure comprises a pre-tightening rib (240) and a pre-tightening wheel (250); the pre-tightening rib (240) is fixed to a side wall of the upper cover (230) and obliquely extends from front to back and from top to bottom in the longitudinal direction of the upper cover (230); the pre-tensioning wheels (250) are mounted to inner sides of the vertical plates (212) so as to be rotatable about an axis parallel to the transverse direction of the upper cover (230); and during the process of pushing the drawer (220) to the support (210), the pre-tightening ribs (240) gradually move to the lower portions of the pre-tightening wheels (250) along with the upper cover (230), such that the pre-tightening wheels (250) elastically press the pre-tightening ribs. By means of the drawer assembly, the drawer (220) can be pushed and pulled relatively smoothly, and when the drawer (220) is closed, the upper cover (230) can be pressed on the drawer (220) to ensure the sealing of the drawer (220).
