Refrigerator and drawer assembly of refrigerator

Abstract

The invention relates to a refrigerator and a drawer assembly of the refrigerator. The drawer assembly includes a drawer. The left and right sides of the drawer assembly are provided with an upper guiding strip and a lower guiding strip. Two supporting assemblies are fixed to the left and right sides of a storage compartment separately. Each supporting assembly includes a supporting frame providedwith an upper sliding groove and a lower sliding groove. Each lower sliding groove is provided with a front vertical section, a horizontal section and a back vertical section. A connecting piece includes a sliding part and a rotation part which are mounted in the upper sliding grooves. The rotation part is provided with a front guiding column penetrating into the lower sliding groove. The front guiding column is provided with a block stopping part. The end parts of the block stopping part and the end part of the rotation part are separately clamped on the left and right sides of the lower sliding grooves. An elastic component applies an elastic force to the connecting piece. When the drawer is closed, the upper guiding strip moves backwards and downwards presses the front guiding column to make the front guiding column be separated from the front vertical section to enter the horizontal section and abut against the front of the lower guiding strip, so that the drawer can be pushed backwards under action of the elastic force. When the drawer moves frontwards, the lower guiding strip pushes the front guiding column frontwards to make the front guiding column be clamped into the front vertical section. When the drawer is in an abnormal condition and moves backwards, the lower guiding strip moves backwards and downwards presses the front guiding column to make the front guiding column enter the back vertical section to make the lower guiding strip go cross the front guiding column, so that the front guiding column is located in front of the lower guiding strip again.

Description

technical field [0001] The invention relates to a refrigerating and freezing device, in particular to a refrigerator and a drawer assembly thereof. Background technique [0002] The drawer of the refrigerator is generally arranged in the storage compartment in a pushable and pullable manner. Many drawers adopt a power-assisted closing mechanism. After the drawer is pushed into the storage compartment to a certain extent, the user can let go, and the drawer automatically moves back under the action of the spring until it is completely closed. [0003] However, the existing power-assisted closing mechanisms have a relatively complex structure and low reliability, and are prone to failure. Contents of the invention [0004] An object of the present invention is to overcome at least one defect of the prior art and provide a refrigerator and its drawer assembly with a novel and simple structure, so that the drawer can be closed automatically and has high reliability and is not...
