Refrigerator and elevation device for refrigerator

Abstract

The embodiment of the invention provides a refrigerator and an elevation device for the refrigerator. The elevation device for a refrigerator drawer includes a lower frame, an upper frame, and a lifting assembly. The lifting assembly includes: a pair of first rods having a first end rotatably coupled to the lower frame and a second end that translates along the upper frame; and a pair of second rods having a first end rotatably coupled to the upper frame and a second end that translates along the lower frame. The second rod is rotatably coupled to and crosses the first rod. The first or secondrod is connected to a driving device via the first end of the first or second rod, with the driving device disposed outside the upper frame and the lower frame. The first and second rods are configured to, based on power from the driving device, rotate about their respective first ends to elevate the upper frame relative to the lower frame.

Description

technical field [0001] The invention relates to a refrigerator and a lifting device for the refrigerator. Background technique [0002] Generally, a refrigerator is a home appliance for low-temperature storage of food in an internal storage space covered by a door of the refrigerator. For this reason, the refrigerator cools the inside of the storage space using cold air generated by heat exchange with the refrigerant circulating in the refrigeration cycle, thereby being able to keep stored food in an optimal state. [0003] With the change of dietary life and the trend of high-end products, recent refrigerators have gradually become larger and more multi-functional. For the convenience of users and the effective use of internal space, various structures and convenience devices are constantly appearing. refrigerator. [0004] The storage space of the refrigerator can be opened and closed through the refrigerator door. In addition, refrigerators can be classified into vario...

AI Technical Summary

Problems solved by technology

However, in this structure, when the refrigerator door is fully drawn out, not only the loss of cold air in the refrigerator will be increased, but also there will be stability such as sagging due to the load generated by the door, storage compartment and lifting mechanism in the drawn state. question

Therefore, it is necessary to improve the structure for drawing out / introducing, and there is a structure that is difficult to be practically applied to a bulky storage room or a refrigerator door
