refrigerator

Abstract

The invention provides a refrigerator. The refrigerator is provided with a rack assembly on the bottom surface of the drawer door, and the rack assembly has a first rack member and a second rack member that are sequentially advanced and pulled out, so that the drawer door can be pulled out. In addition, a noise reduction part is provided between the stopper member and the restriction protrusion constituting the rack assembly, so that impact noise can be reduced even when a collision occurs between the stopper member and the restriction protrusion , and prevent damage caused by impact.

Description

technical field [0001] The present invention relates to a refrigerator having a drawer-type door that is automatically drawn out in the form of a drawer. Background technique [0002] In general, refrigerators are home appliances that store various foods or beverages for a long period of time using cold air generated by a refrigerant cycle based on a refrigeration cycle. [0003] The refrigerators described above are classified into refrigerators that can be stored in common regardless of the types of storage items such as food or drink to be stored, and dedicated refrigerators that differ in size or function depending on the types of storage items to be stored. [0004] The special refrigerators include kimchi refrigerators, wine refrigerators, and the like. [0005] In addition, refrigerators can be classified into refrigerators with revolving doors, refrigerators with drawer doors, and hybrid open-close refrigerators according to different opening and closing methods of ...

Problems solved by technology

[0013] However, in the aforementioned prior art, guide racks formed with racks are respectively provided on both side wall surfaces of the box, and guide racks are provided on both side wall surfaces (or, on the rear surface) of the storage portion constituting the drawer type door. Both sides) are respectively provided with pinion gears, thereby forming a structure for moving the drawer-type door back and forth, therefore, the pull-out distance of the drawer-type door is limited

[0014] That is, considering that the pull-out distance of the drawer-type door is proportional to the length of the guide rack, if the guide rack is not set to protrude from the inner space in the box to the outside, the storage portion of the drawer-type door cannot be removed from the inside of the box. The inner space of the box body is completely exposed, so it is inevitably inconvenient to take out the storage items stored in the storage part.

[0015] Further, in the aforementioned prior art refrigerator drawer door, during the push-in process of the drawer door, impact noise may be caused due to the collision phenomenon of the structure preventing the drawer door from being excessively inserted.

[0016] In particular, in an automatic operation type drawer door provided with a guide rack and pinion, it is necessary to prevent excessive pushing of the guide rack or a structure for fixing to a specific part, but such a part must also be designed to A structure that prevents noise or damage due to contact shock that occurs when the drawer door is pulled out or pushed in
