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 cabinet; a first storage compartment within the cabinet; a first door having an upper surface, a lower surface, a first side surface, and a second side surface, the first door rotatably configured to open and close at least a portion of the first storage compartment; a storing device that is coupled to the first door and that defines a second storage compartment, the second storage compartment being disposed in the first storage compartment when the first door is oriented in a closed position and the second storage compartment being configured to move with the first door when the first door rotates between opened and closed positions; a second door having an upper surface, a lower surface, a first side surface, and a second side surface, the second door rotatably mounted to an upper portion of the first door, that is configured to open and close the second storage compartment in a same direction as a rotation direction of the first door, and that is configured to enable access to the second storage compartment when the first door is oriented in a closed position and the second door is oriented in an open position; a first hinge connecting the upper surface of the first door to an upper surface of the cabinet; a second hinge connecting the upper surface of the second door to the upper surface of the first door; a locking unit configured to lock the second door to the first door; and a release member configured to receive a user input, wherein the locking unit is configured to release the second door from the first door based on the release member receiving the user input, and wherein the locking unit also is configured to release the second door from the first door based on a pressing force applied to a front surface of the second door at a location spaced apart from the release member or based on a touch of the user input; wherein the second door, on the upper portion of the first door, is positioned above a lower portion of the first door in a position at which the front surface of the second door is generally coplanar with a front surface of the lower portion of the first door when the second door is oriented in a closed position; and wherein when the second door is oriented in the closed position, the first side surfaces of the first door and the second door are substantially coplanar, the second side surfaces of the first door and the second door are substantially coplanar, and the upper surfaces of the first door and second door are substantially coplanar. 2. The refrigerator according to claim 1, wherein the locking unit comprises: a latch hook provided to the second door;a latch cam provided to the first door and configured to catch a portion of the latch hook; anda stopper provided to the first door and configured to limit rotation of the latch cam. 3. The refrigerator according to claim 2, wherein the release member comprises: a first member provided to the second door; anda second member that is provided to the first door and that links with the first member. 4. The refrigerator according to claim 3, wherein the first member comprises: an operation button configured to be pressed by a user; anda push rod positioned behind the operation button, the push rod being configured to move together with the operation button, andthe second member comprises a latch rod that is pressed by the push rod. 5. The refrigerator according to claim 4, further comprising an elastic member that is wound around an outer circumferential surface of the push rod to return the push rod to an original position of the push rod when pressure on the operation button is released. 6. The refrigerator according to claim 4, further comprising an elastic member that is wound around an outer circumferential surface of the latch rod to return the latch rod to an original position of the latch rod when pressure on the operation button is released. 7. The refrigerator according to claim 3, wherein the first member operates the second member and, based on the first member operating the second member, the second member pushes the stopper in a direction in which the stopper is removed from the latch cam. 8. The refrigerator according to claim 3, wherein the first member comprises an input member that is positioned on the front surface of the second door and that is configured to receive input of an operation command of the release member, and the second member comprises an actuator that is operated according to an electrical signal based on input received by the input member. 9. The refrigerator according to claim 2, further comprising an elastic member that is provided to a rotation shaft of the latch cam and configured to rotate the latch cam to an original position of the latch cam. 10. The refrigerator according to claim 2, further comprising an elastic member having a first end connected to the stopper and a second end connected to the first door, the elastic member being configured to return the stopper to an original position of the stopper.
