Drawer assemblies and refrigerators

Abstract

The invention discloses a drawer assembly and a refrigerator, comprising a sliding guide rail, a drawer assembled with the sliding guide rail, and a guide rail bracket used to support the sliding guide rail, a rotating mechanism is arranged between the box body and the sliding guide rail, and the sliding guide rail is rotationally connected by the rotating mechanism On the box body; the drawer has a first center of gravity position when it is pushed into the innermost limit position and a second center of gravity position when it is pulled out to the outermost limit position, and the rotation center of the rotating mechanism is set at the first center of gravity position and the second center of gravity Between positions, when the drawer moves to the innermost limit position, the end of the sliding guide rail close to the inner side of the box tilts down; when the drawer moves to the outermost limit position, the end of the sliding guide rail near the outer side of the box tilts down. With the above-mentioned drawer assembly, the drawer has a self-closing function and low noise; at the same time, the problem of large local tension is solved; there is no need to clamp the sliding guide rail on the box body, no sealing is required, the cost is low, the installation and operation efficiency is high, and the 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. Such as 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 heig...

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
