연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

1. A refrigerator, comprising: a main body having a first storage area in which a first plurality of shelves are arranged vertically;a main door rotatably coupled to a front of the main body, the main door configured to be in close contact with a front surface of the main body when the main door is in a closed position;a sub door rotatably coupled to a front of the main door, the sub door configured to be in close contact with a front surface of the main door when the sub door is in a closed position;a first hinge assembly which connects an upper surface of the main door and an upper surface of the main body; anda second hinge assembly which connects an upper surface of the sub door and the upper surface of the main door,wherein the main door includes: a second storage area in which a second plurality of shelves are arranged vertically;an opening part which enables access to the second storage area; anda main door side magnet provided such that the main door is in close contact with the front surface of the main body,wherein the sub door includes a sub door side magnet provided such that the sub door is in close contact with the main door,wherein handles are respectively formed in the main door and the sub door extending in length directions of the doors, such that the main door and the sub door rotate in the same direction to be opened,wherein the sub door is provided in such a manner that the sub door covers a region where the handle of the main door is formed at a front side of the main door,wherein the handle of the main door or the handle of the sub door is configured to be selectively accessible,wherein at least a portion of an upper surface of the sub door and at least a portion of an upper surface of the main door are substantially coplanar,wherein a side surface of the main body, a side surface of the main door and a side surface of the sub door are substantially coplanar; andwherein the magnetic force of the magnet on the main door is configured to be greater than the magnetic force of the magnet on the sub door. 2. The refrigerator according to claim 1, further comprising: a main door side sealer disposed at the main door and accommodating the main door side magnet thereinside; anda sub door side sealer disposed at the sub door and accommodating the sub door side magnet thereinside. 3. The refrigerator according to claim 1, further comprising a housing provided at a rear surface of the main door, wherein the housing is configured to separate the second storage area from the first storage area. 4. The refrigerator according to claim 3, wherein the refrigerator is configured such that the temperature of the second storage area is different from the temperature of the first storage area. 5. The refrigerator according to claim 4, wherein the first storage area includes a refrigerating chamber, and the second storage area includes a refrigerating chamber or a freezing chamber. 6. The refrigerator according to claim 1, wherein the handle of the sub door is a door groove which is recessed in a predetermined depth. 7. The refrigerator according to claim 1, wherein the handle of the main door is a door groove which is recessed in a predetermined depth. 8. The refrigerator according to claim 1, wherein a groove for putting in a user's hand is formed in the handle of the main door. 9. The refrigerator according to claim 1, further comprising a third door in close contact with the main body, wherein the third door includes a handle which faces the handle of the main door. 10. The refrigerator according to claim 1, wherein the sub door is located in front of the handle of the main door in a state in which the sub door is closed, to be accessible to the handle of the main door via a side surface of the sub door. 11. The refrigerator according to claim 1, further comprising a coupling apparatus selectively coupling the main door and the sub door. 12. The refrigerator according to claim 1, further comprising: magnets respectively mounted on rear surfaces of the main door and the sub door, the magnetic force of the magnet on the main door configured to be greater than the magnetic force of the magnet on the sub door; anda coupling apparatus selectively coupling the main door with the sub door,wherein when the coupling apparatus is uncoupled, the sub door is separable from the main door. 13. The refrigerator according to claim 11, wherein the coupling apparatus includes a latch hook. 14. The refrigerator according to claim 12, wherein the coupling apparatus includes a latch hook. 15. A refrigerator, comprising: a main body having a first storage area in which a first plurality of shelves are arranged vertically;a main door rotatably coupled to a front of the main body, the main door configured to be in close contact with a front surface of the main body when the main door is in a closed position;a sub door rotatably coupled to a front of the main door, the sub door configured to be in close contact with a front surface of the main door when the sub door is in a closed position;a first hinge assembly which connects an upper portion of the main door and an upper portion of the main body; anda second hinge assembly which connects an upper portion of the sub door and the upper portion of the main door,wherein the main door includes: a second storage area in which a second plurality of shelves are arranged vertically;an opening part which enables access to the second storage area and having a size corresponding to an opened part of the first storage area; anda main door side magnet provided such that the main door is in close contact with the front surface of the main body,wherein the sub door includes a sub door side magnet provided such that the sub door is in close contact with the main door,wherein handles are respectively formed in the main door and the sub door extending in length directions of the doors, such that the main door and the sub door rotate in the same direction to be opened,wherein the sub door is provided in such a manner that the sub door covers a region where the handle of the main door is formed at a front side of the main door,wherein the handle of the main door or the handle of the sub door is configured to be selectively accessible,wherein at least a portion of an upper surface of the sub door and at least a portion of an upper surface of the main door are substantially coplanar,wherein a side surface of the main body, a side surface of the main door and a side surface of the sub door are substantially coplanar; andwherein the magnetic force of the magnet on the main door is configured to be greater than the magnetic force of the magnet on the sub door.
