A refrigerator comprises: a body having a storage chamber; a door for selectively shielding the storage chamber; a hinge coupling portion for hinge-coupling the door to the body; and a height control unit for lifting up or lowering the door by repeatedly opening and closing the door. Since the door has a controllable height by being opened and closed, a moment arm becomes longer than when using the conventional tool such as a spanner. This may allow the height of the door to be controlled by using less force. Since the height of the door is controllable at a user's eye height, the user may control the height of the door more rapidly and precisely without errors.

1. A refrigerator, comprising: a body having a storage chamber;a door for selectively shielding the storage chamber;a hinge coupling portion coupled to the body; anda height control unit for lifting up or lowering the door,wherein the height control unit comprises: a hinge portion having a first end screw-coupled to the hinge coupling portion, and a second end configured to rotatable support the door, anda height controller configured to rotate the hinge portion in a locking manner based on the door being opened and closed, andwherein the height controller comprises: a plurality of hooking portions located at one side of the hinge portion in a circumferential direction,a selection lever configured to selectively lock the hinge portion,locking members selectively coupled to the hooking portions by the selection lever, the locking members causing the hinge portion to rotate responsive to opening and closing of the door based on the selection lever causing at least one of the locking members to couple to at least one of the hooking portions such that the door lifts up or lowers responsive to opening and closing of the door, anda lever bracket portion fixed to the door, and to which the selection lever and the locking members are coupled. 2. The refrigerator of claim 1, wherein the hinge coupling portion is provided on one of upper and lower surfaces of the door, and the height control unit is provided on another of the upper and lower surfaces where the hinge coupling portion is not provided. 3. The refrigerator of claim 1, wherein the height controller is installed at the door. 4. The refrigerator of claim 3, wherein the height control unit further comprises a hinge bracket portion fixed to the body, and to which the hinge portion is screw-coupled so as to be movable in upper and lower directions. 5. The refrigerator of claim 1, wherein the selection lever is exposed to outside of the lever bracket portion, and is configured such that a lifting mode, a lowering mode, and a neutral mode of the hinge portion is selected. 6. The refrigerator of claim 3, wherein the hinge portion is rotated by being locked by the height controller only in one state of an opened state and a closed state of the door. 7. The refrigerator of claim 1, wherein the hooking portions are formed in a lengthwise direction of the hinge portion, and are implemented as a plurality of grooves entirely formed at the hinge portion in a circumferential direction. 8. The refrigerator of claim 7, wherein the hooking portions are extending from the hinge portion by a predetermined length in a radius direction. 9. The refrigerator of claim 1, wherein the lever bracket portion is insertion-fixed to an upper surface or a lower surface of the door. 10. The refrigerator of claim 1, wherein the locking members are disposed at both sides of the hooking portions, and have one side rotatably coupled to the lever bracket portion, and wherein the locking members come in contact with the hooking portions by the selection lever, thus to selectively lock rotation of the hinge portion in one direction. 11. The refrigerator of claim 10, wherein two locking members are coupled to the selection lever, and only one of the two locking members comes in contact with the hooking portions by the selection lever. 12. The refrigerator of claim 1, wherein a contact portion of the selection lever contacting the locking members is provided in a predetermined cam shape so that only one of two locking members comes in contact with the hooking portions when the selection lever is rotated. 13. The refrigerator of claim 4, wherein a separation prevention portion for preventing separation of the hinge portion from the hinge bracket portion is formed at the end of the hinge portion. 14. The refrigerator of claim 12, wherein the two locking members comprise contact grooves, respectively, having contact portions of the selection lever inserted into the contact grooves for allowing the two locking members to be spaced from the hooking portions so as to remain in a neutral mode, and wherein the two locking members are elastically supported on the lever bracket portion, respectively, by elastic members.
