Abstract

The invention relates to a refrigerating and freezing device and a drawer module thereof. The drawer module comprises a cylinder, a drawer inserted in the cylinder in a front-back pushing / pulling manner, and at least one locking mechanism; the locking mechanism includes a pivot latch pivoted at the front part of the cylinder around transverse axis, and a front clamping tooth and a back clamping tooth extend from the upper end; a clamping piece is arranged at the front part of the drawer, and is provided with a clamping hole for penetrating through the upper and lower surfaces thereof; when the drawer is located in a closing state, the front clamping tooth is inserted in the clamping hole, and at this time, the pivot latch is in a first position; when the drawer is forwards pulled, the pivot latch is pivoted from the first position to a second position to enable the front clamping tooth to deviate from the clamping hole; when the drawer is backwards pushed, and the clamping piece backwards pushes the back clamping tooth to enable the front clamping tooth to enter the clamping hole; and an elastic element is configured to apply the resistance torque to the pivot latch in the process of pivoting the pivot latch from the first position to the second position or from the second position to the first position. The locking mechanism is simple and novel in structure, and is convenient for users to open or close the drawer.

Description

technical field [0001] The invention relates to a refrigerating device, in particular to a refrigerating and freezing device and a drawer assembly thereof. Background technique [0002] The drawer of the refrigerating and freezing device is generally arranged in a cylindrical body in a push-and-pull manner. With the improvement of food preservation requirements, it is necessary to form a good seal between the front panel of the drawer and the front opening of the cylinder after the drawer is fully pushed into the cylinder, that is, it is necessary to make the front panel close to the cylinder. Front opening. [0003] For this reason, the existing refrigerating and freezing devices are equipped with complex mechanical or electromagnetic locking mechanisms to lock the drawer and the cylinder body, but the existing locking mechanisms are complex in structure and difficult to manufacture, cumbersome in operation and difficult to control, or high in cost . Contents of the inv...
