1. A refrigerator, comprising: a body;a storage compartment formed at an inside of the body;an inner door having an opening corresponding to the storage compartment, and a door frame forming the opening, the inner door being rotatably coupled to the body;a plurality of door guards provided at the opening; andan outer door to open/close the opening,wherein the inner door comprises an inner panel, an outer panel, an insulation material disposed in between the inner panel and the outer panel, an installation member coupled to the inner panel, and a gasket installed at the installation member to seal in between the body and the inner panel,wherein the inner panel comprises an accommodation groove to accommodate the installation member,wherein the inner panel comprises a plurality of accommodation protrusions formed in the accommodation groove to fix the installation member,wherein the plurality of accommodation protrusions comprise a plurality of pairs of accommodation protrusions protruding toward both sides of the installation member, andwherein the plurality of pairs of accommodation protrusions are spaced apart from each other. 2. The refrigerator of claim 1, wherein: the inner panel comprises a pair of inner side walls configured to form the opening and support the door guards, andthe inner side walls are formed to be flat from an entry of the opening to an exit of the opening, and a distance between the pair of inner side walls is constant from the entry of the opening to the exit of the opening. 3. The refrigerator of claim 1, wherein: the inner panel comprises a plurality of accommodation protrusions protruding toward an inner side of the accommodation groove to fix the installation member. 4. The refrigerator of claim 3, wherein: the plurality of accommodation protrusions are formed at a portion of the accommodation groove while being spaced apart from one another. 5. The refrigerator of claim 3, wherein: the installation member comprises insertion grooves into which the accommodation protrusions are inserted. 6. The refrigerator of claim 1, wherein: the inner panel is injection-molded by use of resin. 7. The refrigerator of claim 1, wherein: the installation member comprises an installation groove at which the gasket is installed, and installation protrusions protruding toward an inner side of the installation groove to fix the gasket. 8. The refrigerator of claim 7, wherein: the installation protrusions is successively formed at an entire area of the installation groove lengthwise along the installation member. 9. The refrigerator of claim 1, wherein: the installation member is extrusion-molded. 10. The refrigerator of claim 1, wherein: the inner panel comprises an upper frame, a lower frame, a left frame, and a right frame, andthe first installation member, second installation member, third installation member and fourth installation member are installed at the upper frame, the lower frame, the left frame, and the right frame, respectively. 11. The refrigerator of claim 1, wherein: the outer panel is formed of metal, andthe outer door comprises a gasket configured to seal in between the inner door and the outer door, and the gasket comprises a magnet. 12. A refrigerator, comprising: a body;a storage compartment formed at an inside the body;an inner door having an opening corresponding to the storage compartment, an inner panel, an outer panel, and an insulation material disposed in between the inner panel and the outer panel, the inner door rotatably coupled to the body;a gasket assembly to seal in between the inner door and the body;a plurality of door guards provided at the opening; andan outer door rotatably coupled to the body to open and close the opening,wherein the inner panel comprises an accommodation groove formed at a rear surface of the inner panel so that the gasket assembly is coupled thereto,wherein the gasket assembly comprises an installation member accommodated in the accommodation groove, and a gasket installed at the installation member,wherein the installation member comprises a first installation member, a second installation member, a third installation member and a fourth installation member, andwherein the first, second, third and fourth installation members are spaced apart from one another. 13. The refrigerator of claim 12, wherein: the inner panel comprises a pair of inner side walls configured to form the opening and support the door guards, andthe inner side walls are formed to be flat from an entry of the opening to an exit of the opening, and a distance in between the pair of inner side walls is constant from the entry of the opening to the exit of the opening. 14. The refrigerator of claim 12, wherein: the inner panel is injection-molded by use of resin. 15. A method of manufacturing a refrigerator, having a body, a storage compartment formed at an inside the body, an inner door having an opening corresponding to the storage compartment and rotatably coupled to the body, a plurality of door guards provided at the opening, and an outer door rotatably coupled to the body to open/close the opening, the method comprising: injection-molding an inner panel having an accommodation groove to accommodate an installation member;inserting the installation member into the accommodation groove; andinstalling a gasket at the installation member,wherein the installation member comprises a first installation member, a second installation member, a third installation member and a fourth installation member, andwherein the first, second, third and fourth installation members are spaced apart from one another. 16. The method of claim 15, wherein injection molding the inner panel comprises forming a pair of inner side walls configured to form the opening and support the door guards. 17. The method of claim 16, wherein forming the pair of inner side walls comprises forming the inner side walls to be flat from an entry of the opening to an exit of the opening. 18. The method of claim 17, wherein a distance in between the pair of inner side walls is constant from the entry of the opening to the exit of the opening. 19. The method of claim 15, wherein installing the gasket comprises receiving the gasket in an installation groove in the installation member, and fixing the gasket with an installation protrusion protruding inward of the installation groove.
