Drawer assembly and refrigerator

Abstract

The invention discloses a drawer assembly and a refrigerator. The drawer assembly comprises a sliding guide rail, a drawer assembled with the sliding guide rail, and a guide rail bracket for supporting the sliding guide rail; a rotating mechanism is arranged between a refrigerator body and the sliding guide rail, and the sliding guide rail is rotatably connected to the refrigerator body through the rotating mechanism; the drawer has a first gravity center position when pushed to the innermost-side limiting position and a second gravity center position when pulled out to the outermost-side limiting position; the rotation center of the rotating mechanism is arranged between the first gravity center position and the second gravity center position; when the drawer moves towards the innermost-side limiting position, the end, close to the inner side of the refrigerator body, of the sliding guide rail is downwards inclined; and when the drawer moves towards the outermost-side limiting position, the end, close to the outer side of the refrigerator body, of the sliding guide rail is downwards inclined. By applying the drawer assembly, the drawer has a self-closing function, and noise is small; meanwhile the problem of large local tensile force is solved; and the sliding rail does not need to be clamped on the refrigerator body, sealing is not needed, the cost is low, the mounting operation efficiency is high, and maintainability is good.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a drawer assembly and a refrigerator. Background technique [0002] The simple guide rails used on refrigerators usually use partial drop on the guide rail or the track surface of the guide rail is an inclined plane to form a certain drop, so that the drawer has a certain self-closing function when pushed back and reset. like figure 1 As shown, in the process of pulling out the drawer, when the drawer is moving from point A' to point B', the drawer is doing a climbing motion, which requires a large pulling force. When the drawer moves from point B' to point C', it is a smooth motion During the process, just pull out with uniform force; during the drawer push back reset process, when the drawer moves from point C' to point B', it is a smooth motion process, just keep a constant thrust. When the drawer moves to point B', due to B' to point B' A' There is a height ...

AI Technical Summary

Problems solved by technology

[0003] With this structure, it is difficult to pull out the drawer, and the impact force between the drawer and the guide rail is large and the noise is large when resetting.

And it is necessary to make a specific guide rail assembly structure on the cabinet, which increases the cost of the mold, and it is not very convenient to install and remove the guide rail, which affects production efficiency and user experience
