Refrigerator

Abstract

The present invention relates to a refrigerator, wherein a rack gear assembly is provided on a lower surface of a drawer, and the rack gear assembly has a first rack member and a second rack member that are pushed out by being moved forward sequentially so that a pushing-out distance of the drawer is maximized and the drawer is fully closed even when opposite sides thereof are pushed in a storagechamber without being in parallel.

Description

technical field [0001] The present invention relates to a refrigerator having a drawer-type door that is automatically pulled out in the form of a drawer. Background technique [0002] In general, a refrigerator is a household appliance that generates cold air using a refrigerant cycle in a refrigeration cycle and stores various foods and drinks for a long period of time using the cold air. [0003] Such refrigerators are classified into: refrigerators that can be stored together regardless of the type of storage such as food or drink to be stored; and dedicated refrigerators that have different sizes or functions depending on the type of storage to be stored. [0004] The dedicated refrigerators include pickle refrigerators, wine refrigerators, and the like. [0005] In addition, refrigerators are classified into refrigerators equipped with revolving doors, refrigerators equipped with drawer doors, and hybrid open-close type refrigerators according to the door opening and ...

Problems solved by technology

[0013] However, in the aforementioned prior art, guide racks formed with rack gears are respectively provided on both side wall surfaces of the box body, and guide racks are provided on both side wall surfaces (or , both sides of the back) are respectively provided with small gears to make the drawer-type door move back and forth, therefore, the pull-out distance of the drawer-type door will be limited

[0014] That is, when considering that the pull-out distance of the drawer-type door is proportional to the length of the guide rack, if the guide rack cannot be protruded from the inner space of the box toward the outside, the storage portion of the drawer-type door will It cannot be completely exposed from the inner space of the box body, so it will inevitably become inconvenient to take out the storage items stored in the storage part

[0015] In addition, in the drawer-type door of the refrigerator according to the aforementioned prior art, during the process of pushing the drawer-type door, if the rack teeth of the guide racks on both sides cannot mesh with the pinion gears on both sides in parallel, but any If the rack teeth of the guide rack on one side mesh with either pinion earlier than the rack teeth of the guide rack on the other side, the drawer door cannot be pushed into the storage room accurately.

[0016] Especially, in the case of the above-mentioned problem, the meshing between the pinion gear and the rack teeth of the guide rack is not accurately achieved, which may cause malfunction of the operation, and the door and the box may not be properly attached, and may Will be in an open state, when the drawer door is pulled out later, there may be concerns that the pull-out action will not be smooth

[0017] In addition, since the horizontal mesh between the rack teeth and pinion of each guide rack is not achieved, and the mesh is misaligned, there may be concerns of damage to the pinion or rack teeth
