refrigerator

Abstract

According to the refrigerator of the present invention, the rack assembly is provided on the bottom surface of the drawer door, and the rack assembly includes the first rack member and the second rack member that are pulled out while sequentially moving forward, thereby It is possible to maximize the pull-out distance of the drawer door, and to completely close the drawer door even if both sides of the drawer door are obliquely pushed in during the push-in process of the drawer door.

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 home appliance provided by generating cold air by the circulation of a refrigerant based on a refrigeration cycle, and storing various foods or beverages for a long period of time by using the cold air. [0003] Such refrigerators can be classified into refrigerators that can be collectively stored regardless of the type of storage items to be stored, such as food and beverages, and dedicated refrigerators that have different sizes and functions depending on the type of storage items to be stored. [0004] The special refrigerators include kimchi refrigerators, wine refrigerators, and the like. [0005] In addition, refrigerators are classified into refrigerators including a revolving door, refrigerators including a drawer door, and a hybrid open-close refriger...

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
