AI Technical Summary

Technical Problem

The poor sealing between the drawers and lids of existing refrigerators allows cold air to circulate, affecting food preservation and potentially causing bacterial growth and cross-contamination of odors.

Method used

The cover plate and mounting plate are connected by a linkage assembly, including a reset component and a unit assembly. The elastic deformation of the reset component achieves bistable state of the cover plate, ensuring the stability of the cover plate when the drawer is opened and closed, reducing friction and improving sealing.

Benefits of technology

This design achieves a stable connection between the drawer and the lid, reduces the flow of cold air, improves food preservation and user experience, and prevents bacterial growth and cross-contamination of odors.

Abstract

The application discloses a fresh-keeping assembly and a refrigerator with the same, wherein the fresh-keeping assembly comprises a drawer, a mounting plate, a cover plate and a push plate, the drawer has a top-open containing cavity; the cover plate is connected to the mounting plate through a linkage assembly, the linkage assembly comprises a reset member and at least two unit assemblies, and the reset member is connected to the unit assemblies; each unit assembly comprises a first linkage and a second linkage which are rotationally connected to each other, the first linkage is rotationally connected to the mounting plate, and the second linkage is rotationally connected to the cover plate; and the push plate is connected to the lower side of the cover plate. In the closed state, the cover plate is pressed by the linkage assembly, so that the cover plate and the drawer are relatively stable; in the open state, the cover plate is reset by the linkage assembly, so that the cover plate and the drawer are separated, the friction between the cover plate and the drawer is reduced, and the cover plate is kept in the reset state, thereby realizing the bistable state of the cover plate and improving the use experience of the user.
