Refrigerator with drawer type door

Abstract

A refrigerator includes a drawer door installed at a refrigerator main body such that the drawing door is drawn out from the refrigerator main body, a main storage bin provided to be drawn out along with the drawer door, sub storage bins rotatably provide at an upper portion of the main storage bin, and a container opening unit for opening the sub storage bins toward an outer side of the refrigerator main body in a lateral direction when the drawer door is opened. When the drawer door is closed, the sub storage bins are restrained from being rotated by the refrigerator main body.

1 . A refrigerator, comprising:
 a refrigeration main body;   a drawer door installed at the refrigerator main body and configured to be drawn out from the refrigerator main body;   a main storage bin configured to be drawn out along with the drawer door;   at least one sub storage bin rotabably positioned at an upper portion of the main storage bin; and   a container opening unit for rotating the at least one sub storage bin toward an outer side of the refrigerator main body in a lateral direction when the drawer door is opened,   wherein the at least one sub storage bin is restrained from being rotated by the refrigerator main body when the drawer door is closed.   
     
     
         2 . The refrigerator of  claim 1 , wherein the at least one sub storage bin comprises a pair of sub storage bins, and the pair of sub storage bins are rotated in different directions. 
     
     
         3 . The refrigerator of  claim 1 , wherein the container opening unit comprises a hinge shaft extending from the at least one sub storage bin inserted into the main storage bin. 
     
     
         4 . The refrigerator of  claim 3 , wherein the container opening unit further comprises a torsion spring installed at the hinge shaft. 
     
     
         5 . The refrigerator of  claim 2 , wherein at least one side wall of each of the pair of sub storage bins has an arc shape. 
     
     
         6 . The refrigerator of  claim 1 , further comprising a stopper extending downwardly from the at least one sub storage bin, the stopper engaging the main storage bin when the sub storage bin is rotated. 
     
     
         7 . The refrigerator of  claim 1 , further comprising a cover positioned above the at least one sub storage bin, the cover slidably installed at the refrigerator main body. 
     
     
         8 . The refrigerator of  claim 7 , wherein at least a portion of the cover is made of a transparent material. 
     
     
         9 . The refrigerator of  claim 1 , further comprising at least one partition member in an internal space of the main storage bin. 
     
     
         10 . The refrigerator of  claim 9 , wherein the at least one partition member is slidably mounted in the internal space of the main storage bin. 
     
     
         11 . The refrigerator of  claim 9 , further comprising:
 a rod parallel to a front edge of the main storage bin;   an aperture in the at least one partition member,   wherein the rod extends through the aperture so that the at least one partition member is slidable along the rod.   
     
     
         12 . A refrigerator, comprising:
 a refrigerator main body;   a main storage bin slidably mounted in the refrigerator main body, the main storage bin having a front wall and two side walls;   a pair of sub storage bins mounted to be rotatable with respect to the main storage bin; and   a drawing unit configured to draw the main storage bin from the refrigerator main body;   wherein the pair of sub storage bins rotate beyond each side of the main storage bin when the main storage bin is drawn out.   
     
     
         13 . The refrigerator of  claim 12 , wherein a hinge shaft on each of the pair of sub storage bins is connected to the main storage bin. 
     
     
         14 . The refrigerator of  claim 13 , further comprising a torsion spring connected to the hinge shaft and the main storage bin to rotate the sub storage bins. 
     
     
         15 . The refrigerator of  claim 12 , further comprising a cover positioned above the sub storage bins or an upper portion of the main storage bin, the cover slidably installed at the refrigerator main body. 
     
     
         16 . The refrigerator of  claim 15 , wherein at least a portion of the cover is made of a transparent material. 
     
     
         17 . The refrigerator of  claim 12 , wherein the drawing unit includes a drawer door mounted in the refrigerator main body such that drawing unit is drawn out. 
     
     
         18 . The refrigerator of  claim 12 , further comprising a container opening unit applying a rotational force to the sub storage bins to rotate the sub storage bins when the drawing unit is opened. 
     
     
         19 . The refrigerator of  claim 18 , wherein the container opening unit comprises a torsional spring. 
     
     
         20 . The refrigerator of  claim 12 , further comprising roller members on edges of the sub storage bins engaging the refrigerator main body.
