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.

A refrigerator includes a cabinet that defines a first storage compartment, a first door that is opened or closed to allow or prevent access to an interior of the first storage compartment, a storing device coupled to the first door to define a second storage compartment, and a second door connected to the first door that is opened or closed to allow or prevent access to an interior of the second storage compartment. The first door includes a plurality of first coupling parts to which the storing device is coupled. The storing device includes a frame and a basket installed on the frame, each including at least one second coupling part interacting with at least one of the plurality of first coupling parts. A front surface of the second door is positioned to be generally coplanar with at least a portion of a front surface of the first door.

1. A refrigerator, comprising: a cabinet;a first storage area within the cabinet;a first door having a front surface, a rear surface, an upper surface, a lower surface, a first side surface, and a second side surface, the first door being rotatably connected to the cabinet and configured to open and close at least a portion of the first storage area such that, when the first door is oriented in a closed position, the rear surface of the first door covers a front surface of the cabinet, the first door including: an access opening, anda second storage area located at a rear portion of the first door and accessible through the access opening;a second door having a front surface, a rear surface, an upper surface, a lower surface, a first side surface, and a second side surface, the second door being rotatably connected to the first door and configured to open and close the access opening by rotating in a same direction as a rotation direction of the first door such that, when the second door is oriented in a closed position, the rear surface of the second door covers the front surface of the first door to close the access opening, the second door being thinner than the first door such that, when the first and second doors are oriented in closed positions, a distance between the front surface of the first door and the front surface of the second door is less than a distance between the front surface of the first door and the front surface of the cabinet;a first hinge connecting the upper surface of the first door to an upper surface of the cabinet and positioned closer to the first side surface of the first door than the second side surface of the first door;a second hinge connecting the upper surface of the second door to the upper surface of the first door and positioned closer to the first side surface of the second door than the second side surface of the second door;a hooking member located at one of the first door and the second door;a locking unit located at the other of the first door and the second door at which the hooking member is not located, the locking unit being configured to confine the hooking member into a confined state and to also release the hooking member from the confined state;gasket provided on the rear surface of the second door and configured to be compressed to provide a seal between the rear surface of the second door and the front surface of the first door when the second door is in the closed position; anda limiting member disposed at one of the first door and the second door,wherein the locking unit is configured to release the hooking member based on a pressing force being applied to the front surface of the second door that is greater than a repulsive force being applied to the second door from the limiting member,wherein the limiting member is configured to, based on the second door being closed, apply, to the second door, the repulsive force to thereby prevent the hooking member from being released when the first door is rotated to be opened, andwherein when the second door is in the closed position, the first side surfaces of the first and the second door are substantially coplanar, the second side surfaces of the first and the second door are substantially coplanar, and the upper surfaces of the first and second doors are substantially coplanar. 2. The refrigerator according to claim 1, wherein the hooking member includes a latch hook, and the locking unit includes a latch cam configured to confine the latch hook. 3. The refrigerator according to claim 2, wherein the latch hook is configured to be confined by the latch cam when the second door is pushed toward the first door. 4. The refrigerator according to claim 3, wherein when the latch hook is confined by the latch cam, the latch hook is configured to be released from the latch cam when the second door is pushed toward the first door. 5. The refrigerator according to claim 1, wherein the first door includes: a first part; anda second part positioned above the first part, the second part having a thickness that is less than a thickness of the first part,wherein the access opening is defined at the second part of the first door, andwherein the second storage area is located at the rear portion of the first door at the second part. 6.

The refrigerator according to claim 1, wherein the limiting member is formed of an elastically deformable material selected from the group consisting of rubber, silicone, and synthetic resin. 13. The refrigerator according to claim 1, wherein when the second door is oriented in a closed position, the repulsive force is greater than inertia force applied by the second door as the first door is rotated to open. 14. The refrigerator according to claim 1, wherein the limiting member is positioned a predetermined distance away from the hooking member or the locking unit. 15. The refrigerator according to claim 1, wherein the upper surface of the first door includes a first stepped portion that is recessed downward from an uppermost surface of the first door, wherein the upper surface of the second door includes a second stepped portion that is recessed downward from an uppermost surface of the second door, and wherein the first hinge and the second hinge are connected, respectively, to the first and second doors at a space that is defined by the first and second stepped portions when the second door is oriented in a closed position. 16. The refrigerator according to claim 1, wherein a diameter of a first hinge shaft of the first hinge is greater than a diameter of a second hinge shaft of the second hinge. 17.
