A door opening prevention device is provided for a refrigerator. Stoppers are provided on both sides of a stopper plate provided on a ceiling of a refrigerating chamber. First and second doors for selectively opening and closing the refrigerating chamber are provided with catching hooks, respectively. When the first door and the second door close the refrigerating chamber, by allowing the catching hooks to be caught by the stoppers, the first and second doors are prevented from being inadvertently opened. In addition, a leaf spring 61 is provided which provides the catching hooks with an elastic force that prevents the catching hooks from being inadvertently detached from the stoppers in a state in which the catching hooks are caught to the stoppers this structure prevents during the opening and closing operation of any one of the doors the other door from being opened.

What is claimed is: 1. A door opening prevention device in a refrigerator in which a storage space defined in a main body of the refrigerator is opened and closed by at least two doors, the device comprising: at least one stopper provided on a ceiling or bottom of the storage space; at least one catching hook rotatably mounted on at least one of the at least two doors and caught by the at least one stopper in a state in which at least one of the at least two doors is closed; and an elastic member provided on the ceiling or bottom of the storage space separate from the at least one stopper and configured to impart an elastic force onto the at least one catching hook to push the at least one catching hook into close contact with the at least one stopper, wherein the elastic member is provided at a position which is a predetermined distance apart in a rearward direction from the at least one stopper. 2. The door opening prevention device as claimed in claim 1, wherein the at least one stopper includes a guide surface that guides the at least one catching hook according to the opening and closing operation of the at least one of the at least two doors, and a catching surface that faces the elastic member such that the at least one catching hook is caught to the catching surface when the at least one of the at least two doors is closed. 3. The door opening prevention device as claimed in claim 2, wherein the at least one stopper is formed integrally on an inner surface of the storage space or on a side of a stopper plate fixed to the inner surface of the storage space. 4. The door opening prevention device as claimed in claim 2, wherein the at least one catching hook includes a catching protrusion formed at a distal end thereof, the catching protrusion being guided by the guide surface and brought into close contact with the catching surface in a state in which the at least one of the at least two doors is closed, and a seating surface on which a portion between the guide surface and the catching surface is seated in a state in which the at least one of the at least two doors is closed. 5. The door opening prevention device as claimed in claim 1, wherein the at least one catching hook is installed at a distal end of the at least one of the at least two doors to be pivotal within a predetermined range and tends to rotate in a direction in which the at least one catching hook is caught to the at least one stopper while being supported by the elastic member. 6. The door opening prevention device as claimed in claim 1, wherein the at least one catching hook includes a catching protrusion at a distal end thereof and the elastic member is a leaf spring configured to impart an elastic force to bring the catching protrusion into close contact with a catching surface of the at least one stopper and is fixed to a base plate or an inner surface of the storage space. 7. The door opening prevention device as claimed in claim 6, wherein each end of the leaf spring is formed into a curved surface with a predetermined radius of curvature and spaced apart by a predetermined gap from the catching surface of the at least one stopper facing the leaf spring. 8. A door opening prevention device in a refrigerator in which a single storage space defined in a main body of the refrigerator is opened and closed by first and second doors that are pivotal on both ends of the main body, the device comprising: stoppers provided on a ceiling of the storage space corresponding to the first and second doors, respectively; catching hooks rotatably mounted, respectively, on upper surfaces of distal ends of the first and second doors which open and close the storage space by pivoting in a direction in which distal ends of the catching hooks are caught by the stoppers with respect to the other ends thereof, respectively; and an elastic member provided on the ceiling of the storage space separate from the stoppers and configured to impart an elastic force to the catching hooks to push the catching hooks into close contact with the stoppers in a state in which the first and second doors close the storage space, wherein the elastic member is provided at a position which is a predetermined distance apart in a rearward direction from the stoppers. 9. The door opening prevention device as claimed in claim 8, wherein the stoppers are integrally formed on a stopper plate fixed to the ceiling of the storage space, and the elastic member is mounted to the stopper plate. 10. The door opening prevention device as claimed in claim 8, wherein each end of the elastic member is formed in a curved surface with a predetermined radius of curvature to be spaced apart by a predetermined gap from a portion of the stoppers facing the elastic member. 11. The door opening prevention device as claimed in claim 8, wherein the stopper each include: a guide surface that guides a respective catching hook of the catching hooks according to the opening and closing operation of the respective door, the guide surfaces of the stoppers facing each other; and a catching surface that faces the elastic member such that the catching hooks are caught to the respective stopper in a state in which the respective door is closed. 12. The door opening prevention device as claimed in claim 8, wherein the catching hooks are installed at a distal end of the doors, respectively, to be pivotal within a predetermined range in a direction in which the catching hooks are caught to the stoppers, and each includes a catching protrusion which is formed at a distal end thereof and guided by a guide surface and brought into close contact with the catching surface in a state in which the respective door is closed. 13. A door opening prevention device in a refrigerator in which a storage space defined in a main body of the refrigerator is opened and closed by at least two doors, the device comprising: at least one stopper provided on a ceiling or bottom of the storage space; at least one catching hook provided on at least one of the at least two doors and caught by the at least one stopper in a state in which at least one of the at least two doors is closed; and an elastic member in the form of a curved leaf spring provided on the ceiling or bottom of the storage space separate from the at least one stopper and configured to impart an elastic force onto the at least one catching hook to push the at least one catching hook into close contact with the at least one stopper, wherein the elastic member is provided at a position which is a predetermined distance apart in a rearward direction from the at least one stopper. 14. The door opening prevention device as claimed in claim 13, wherein the at least one stopper includes a guide surface that guides the at least one catching hook according to the opening and closing operation of the at least one of the at least two doors, and a catching surface that faces the elastic member such that the at least one catching hook is caught to the catching surface when the at least one of the at least two doors is closed. 15. The door opening prevention device as claimed in claim 13, wherein the at least one catching hook is rotatably installed at a distal end of the at least one of the at least two doors to be pivotal within a predetermined range and tends to rotate in a direction in which the at least one catching hook is caught to the at least one stopper while being supported by the elastic member. 16. The door opening prevention device as claimed in claim 13, wherein the at least one catching hook includes a catching protrusion at a distal end thereof and the curved leaf spring configured to impart an elastic force to bring the catching protrusion into close contact with a catching surface of the at least one stopper and is fixed to a base plate or an inner surface of the storage space. 17. The door opening prevention device as claimed in claim 13, wherein the curved leaf spring is spaced apart by a predetermined gap from a catching surface of the at least one stopper facing the curved leaf spring.
