Disclosed herein is a door hinge structure for a refrigerator. The door hinge structure comprises an upper fixture unit which is screwed to a predetermined front upper portion of a refrigerator body, and has an upper hinge pin to be inserted in a top aperture formed at an upper surface of a refrigerator door, an upper hinge unit which is mounted on the upper surface of the door, and has a through opening for allowing a distal end of the upper hinge pin to be slidably inserted therethrough, the upper hinge unit being coupled with the upper fixture unit by making use of a torsion spring so that it is vertically spaced therewith, a lower fixture unit which is screwed to a predetermined front lower portion of the body, and has a lower hinge pin to be inserted in a bottom aperture formed, at a lower surface of the door, a lower hinge unit which is mounted on the lower surface of the door, and has a through opening for the insertion of the lower hinge pin, and a stopper member which is interposed between the lower fixture unit and the lower hinge unit and is adapted to stop pivotal movement of the door at least one time.

What is claimed is: 1. A door hinge structure for a refrigerator, the door hinge structure comprising: an upper fixture unit screwed to a predetermined front upper portion of a refrigerator body, and having an upper hinge pin to be inserted in a top aperture formed at an upper surface of a refrigerator door; an upper hinge unit mounted on the upper surface of the door, and having a through opening for allowing a distal end of the upper hinge pin to be slidably inserted therethrough, the upper hinge unit being coupled with the upper fixture unit, the upper hinge unit having a torsion spring, the upper hinge unit and the upper fixture unit being vertically spaced apart from each other; a lower fixture unit screwed to a predetermined front lower portion of the body, and having a lower hinge pin to be inserted in a bottom aperture formed at a lower surface of the door; a lower hinge unit mounted on the lower surface of the door, and having a through opening for the insertion of the lower hinge pin; and a stopper member interposed between the lower fixture unit and the lower hinge unit and adapted to stop pivotal movement between a closed position and an open position of the door; wherein the upper hinge unit includes: an upper mount mounted on the upper surface of the door, and having the through-opening; a plate provided at a lower surface of the upper mount so as to surround the through-opening, the plate being insertable in an upper groove formed along an inner periphery of the top aperture; and a hollow insertion column attached to a lower surface of the plate to be vertically aligned with the through opening, into which a torsion spring is inserted. 2. The structure as set forth in claim 1, wherein the stopper member includes: a mount mounted on an upper surface of the lower fixture unit, and having a central opening for the insertion of the lower hinge pin; at least two rounded upwardly-raised lower stops circularly aligned on an upper surface of the mount; and at least two rounded downwardly-raised upper stops circularly aligned around the through opening of the lower hinge unit in an engagable manner with the upwardly-raised lower stops. 3. The structure as set forth in claim 2, wherein the upper fixture unit includes: an upper bracket screwed to the predetermined front upper portion of the body; an upper arm horizontally extending from a lower end of the upper bracket at right angles thereto; and an upper opening perforated in the upper arm for allowing the upper hinge pin to be fixedly inserted therein. 4. The structure as set forth in claim 2, wherein the lower fixture unit includes: a lower bracket screwed to the predetermined front lower portion of the body; a lower arm horizontally extending from an upper end of the lower bracket at right angles thereto; and a lower opening perforated in the lower arm for allowing the lower hinge pin to be fixedly inserted therein. 5. The structure as set forth in claim 2, wherein the lower hinge unit includes: a lower mount mounted on the lower surface of the door, and having the through opening; and a plate provided at an upper surface of the lower mount to surround the through opening, the plate being insertable in a lower groove formed along an inner periphery of the bottom aperture. 6. The structure as set forth in claim 2, wherein each of the upwardly-raised lower stops and the downwardly-raised upper stops includes: a gentle sloped surface at one lateral side thereof so as to be inclined in a door opening direction; and a steep sloped surface at the other lateral side thereof so as to be inclined in a door closing direction. 7. The structure as set forth in claim 6, wherein the upper hinge pin is formed at a bottom wall thereof with a plurality of insertion holes for allowing an upper end of the torsion spring to be selectively inserted therein; the hollow insertion column is formed at a bottom wall thereof with a plurality of insertion holes for allowing a lower end of the torsion spring to be selectively inserted therein; at the center of the bottom wall of the upper hinge pin is vertically attached a support rod; and from the center of the bottom wall of the hollow insertion column a sliding tube extends upwardly for enabling slidable insertion of the support rod. 8. The structure as set forth in claim 1, wherein the upper fixture unit includes: an upper bracket screwed to the predetermined front upper portion of the body; an upper arm horizontally extending from a lower end of the upper bracket at right angles thereto; and an upper opening perforated in the upper arm for allowing the upper hinge pin to be fixedly inserted therein. 9. The structure as set forth in claim 8, wherein the lower fixture unit includes: a lower bracket screwed to the predetermined front lower portion of the body; a lower arm horizontally extending from an upper end of the lower bracket at right angles thereto; and a lower opening perforated in the lower arm for allowing the lower hinge pin to be fixedly inserted therein. 10. The structure as set forth in claim 8, wherein the lower hinge unit includes: a lower mount mounted on the lower surface of the door, and having the through opening; and a plate provided at an upper surface of the lower mount to surround the through opening, the plate being insertable in a lower groove formed along an inner periphery of the bottom aperture. 11. The structure as set forth in claim 1, wherein the lower fixture unit includes: a lower bracket screwed to the predetermined front lower portion of the body; a lower arm horizontally extending from an upper end of the lower bracket at right angles thereto; and a lower opening perforated in the lower arm for allowing the lower hinge pin to be fixedly inserted therein. 12. The structure as set forth in claim 11, wherein the lower hinge unit includes: a lower mount mounted on the lower surface of the door, and having the through opening; and a plate provided at an upper surface of the lower mount to surround the through opening, the plate being insertable in a lower groove formed along an inner periphery of the bottom aperture. 13. The structure as set forth in claim 1, wherein the lower hinge unit includes: a lower mount mounted on the lower surface of the door, and having the through opening; and a plate provided at an upper surface of the lower mount to surround the through opening, the plate being insertable in a lower groove formed along an inner periphery of the bottom aperture.
