Refrigerator

Abstract

A refrigerator, which minimizes and easily adjusts a difference of heights of doors, and reduces the number of contact points with a floor of an indoor space, thereby being easily moved and installed. A pair of rear wheels are installed at both corners of a rear part of a bottom surface of a main body and one front wheel is installed at an approximately central point of a front part of the bottom surface so that the refrigerator is moved while the refrigerator is supported at three points. Height adjustable legs, heights of which are adjusted, are installed at both corners of the front part of the bottom surface, and the height adjustable legs together with the front and rear wheels allow the refrigerator to be leveled.

1 . A refrigerator comprising: 
 a main body; and    a rolling unit at a bottom surface of the main body and on which the main body is movable, the rolling unit including one moving member at one of a front part and a rear part of the bottom surface, and a plurality of moving members at the other of the front and rear parts.    
   
   
       2 . The refrigerator as set forth in  claim 1 , wherein the one moving member is at the front part of the bottom surface, the plural moving members are installed at left and right sides of the rear part of the bottom surface, and height height adjustable legs are installed at both corners of the front part of the bottom surface.  
   
   
       3 . The refrigerator as set forth in  claim 1 , further comprising height adjustable legs at left and right sides of the one moving member.  
   
   
       4 . The refrigerator as set forth in  claim 1 , wherein the one moving member is at an approximately central point of the bottom surface.  
   
   
       5 . The refrigerator as set forth in  claim 1 , wherein the number of the plural moving members is two, and the two moving members are respectively disposed at both corners of the rear part of the bottom surface.  
   
   
       6 . A refrigerator comprising: 
 a main body having a pair of doors respectively hinged at right and left corners of a front of the main body;    a rolling unit at a bottom surface of the main body and on which the main body is movable, and including one moving member at one of a front part and a rear part of the bottom surface, and a plurality of moving members at the other of the front and rear parts; and    plurality of height height adjustable legs at both corners of the front part of the bottom surface.    
   
   
       7 . The refrigerator as set forth in  claim 6 , wherein the one moving member is at the front part of the bottom surface, the plural moving members are at left and right sides of the rear part of the bottom surface.  
   
   
       8 . The refrigerator as set forth in  claim 6 , further comprising height adjustable legs at left and right sides of the one moving member.  
   
   
       9 . The refrigerator as set forth in  claim 6 , wherein the one moving member is at an approximately central point of the bottom surface.  
   
   
       10 . The refrigerator as set forth in  claim 6 , wherein the number of the plural moving members is two, and the two moving members are respectively disposed at both corners of the rear part of the bottom surface.  
   
   
       11 . The refrigerator as set forth in  claim 6 , wherein the one moving member is proximate to a point on the bottom surface at which unhinged sides of the doors oppose each other when the doors are closed, and 
 wherein the one moving member supports the unhinged sides of the doors so as to level the doors and retard a tilting of the doors.    
   
   
       12 . A refrigerator moving system, comprising: 
 a pair of height height adjustable legs extending from a bottom surface of the refrigerator at opposing front corners of a side of the bottom surface; and    a rolling unit providing three rollable points of support to the bottom surface, one point of support being at the side or at another side of the bottom surface opposing the side and two points of support being at the other of the side or the another side.    
   
   
       13 . The refrigerator moving system as set forth in  claim 12 , wherein the rolling unit includes rollers at each point of support.  
   
   
       14 . The refrigerator moving system as set forth in  claim 12 , wherein the rolling unit includes rolling balls at each support.  
   
   
       15 . The refrigerator moving system as set forth in  claim 12 , wherein the side is a front side and the another side is a rear side.  
   
   
       16 . The refrigerator moving system as set forth in  claim 12 , wherein heights of the pair of height adjustable legs are separately adjustable to maintain a level condition of the refrigerator when a support surface supporting the refrigerator is not level.  
   
   
       17 . The refrigerator moving system as set forth in  claim 12 , wherein the side is a front side, the one point is at the substantial center of the front side so as to cause the refrigerator to tilt when the refrigerator is not level.
