Refrigerator

Abstract

The invention relates to a refrigerator. The refrigerator includes a cabinet (10) in which an upper storage space and a lower storage space are defined, a door part (31) inserted and withdrawn to openand close the lower storage space, a drawer part (32) connected to the door part so as to be inserted into and withdrawn from the lower storage space, a support member (35) which is provided in the drawer part and on which a food or container is seated, and an elevation device (51) disposed on each of both side surfaces of the drawer part (32) and coupled to each of both side ends of the supportmember (35) to vertically elevate the support member in a state in which the drawer door is withdrawn.

Description

technical field [0001] The present invention relates to refrigerators. 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 various forms according to the arrangeme...

Problems solved by technology

[0013] However, when the control of the air cylinders arranged on both sides is not precise enough, the housing may tilt. In particular, when the load is eccentric to the housing, the eccentricity of the housing may become a serious problem that prevents the housing from being raised or lowered. question

[0014] In addition, in the above-mentioned structure, the cylinder is also exposed from the left and right sides, which may cause a safety problem, and the volume inside the housing may be reduced due to the cylinder and the movable frame arranged on both sides. The problem

[0015] In addition, the prior art as described above has a structure in which the casing forming the storage space or the entire member corresponding to the casing is raised and lowered. In this structure, the load may be eccentric according to the food arrangement inside the storage space, so that there is a problem of lifting and lowering. imbalance problem

[0016] In addition, in order to raise and lower the entire cabinet, it is necessary to completely draw out the cabinet from the storage space in the refrigerator. Due to the increase in the extraction distance of the entire refrigerator door including the cabinet, the introduction / extraction will be unstable, so there is a need to strengthen the Problems with structures such as the tracks that support the refrigerator door

In particular, such a problem may be more serious than the case where a member for lifting is arranged on the door side of the refrigerator.
