The refrigerator of claim 1, wherein the frame is arranged at the cooling chamber to be movable in back and forth directions of the body. 3. The refrigerator of claim 1, further comprising a guide rail installed between the frame and the cooling chamber for guiding the frame to be slid in back and forth directions of the body. 4. The refrigerator of claim 1, wherein the door has a lower end hinge-connected to the frame by a hinge-bracket. 5. The refrigerator of claim 1, wherein the first link has one end hinge-connected to the frame and another end hinge-connected to the basket. 6. The refrigerator of claim 5, wherein the link unit includes a third link having one end hingedly connected to the basket and another end hingedly connected to the frame. 7. The refrigerator of claim 6, wherein the first and third link are arranged substantially parallel throughout the lifting of the basket. 8. The refrigerator of claim 1, wherein a spring for providing an elastic force to the first link is installed at the hinge-connected portion between the first link and the frame. 9. The refrigerator of claim 1, wherein the first link is constructed as one pair, and one first link is longer than another first link. 10. The refrigerator of claim 1, further comprising a locking unit for locking the door to the frame not to rotate the door or releasing a locked state of the door. 11. The refrigerator of claim 10, wherein the locking unit comprises: a locking hole formed at a front side of the frame; a locking hook movably mounted at the door and locked in the locking hole; and a spring for providing an elastic force to the locking hook so that the locking hook can maintain a locked state in the locking hole. 12. The refrigerator of claim 11, wherein the locking hook comprises: a lever portion exposed to a front side of the door and adjusted by a user; a connecting portion integrally connected to the lever portion and movably mounted at the door; and a locking portion formed at an end of the connecting portion and locked by the locking hook. 13. The refrigerator of claim 1, further comprising a stopping unit installed between the frame and the door for preventing the door from being returned to an original state after a rotation. 14. The refrigerator of claim 13, wherein the stopping unit comprises: a rod rotatably connected to the door and having a certain length; a stopping hole formed at the frame for passing the rod; and a stopping protrusion formed at an end of the rod and stopped in the stopping hole. 15. The refrigerator of claim 1, wherein the link unit is configured to lift the basket along an arcuate path. 16. A refrigerator comprising: a body having a cooling chamber; a frame arranged at the cooling chamber and on which a basket for storing food is positioned; a door positioned at a front side of the frame and hinge-connected to the frame; a link unit link-connected between the frame and the basket or between the basket and the door, the link unit being configured to lift the basket and to move the basket horizontally with respect to the frame when the door is rotated; and a driving unit for driving the link unit so as to lift the basket, wherein the link unit comprises: a first link connected between the frame and the basket for guiding the basket to be lifted and supporting a lifted state of the basket; and a second link connected between the first link and the door for lifting the basket when the door is forward rotated. 17. The refrigerator of claim 16, wherein the frame is arranged at the cooling chamber to be movable in back and forth directions of the body. 18. The refrigerator of claim 16, wherein the first link has one end hinge-connected to the frame and another end hinge-connected to the basket. 19. The refrigerator of claim 18, wherein the link unit includes a third link having one end hingedly connected to the basket and another end hingedly connected to the frame. 20. The refrigerator of claim 19, wherein the first and third link are arranged substantially parallel throughout the lifting of the basket. 21. The refrigerator of claim 16, wherein the first link is constructed as one pair, and one first link is longer than another first link. 22. The refrigerator of claim 16, wherein the driving unit comprises: a driving motor mounted at the frame for generating a driving force; and a power transmitting unit for transmitting a driving force generated from the driving motor to a hinge shaft to which the first link is connected. 23.
