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.

The refrigerator of claim 1, wherein the pillar unit comprises a pillar member coupled at either of the upper door or the lower door as to enable a rotation in a vertical direction and provided at one end thereof with a guide protrusion, a pillar guide installed onto a side of the vertical partition wall and having a guide groove, to which the guide protrusion is inserted, such that the rotation of the pillar member is guided, and a torsion spring configured to elastically support the pillar member in a state that the pillar member is rotated upward by the pillar guide. 3. The refrigerator of claim 1, wherein the front side plate has a width corresponding to a front edge of the cabinet. 4. The refrigerator of claim 1, wherein the reinforcing bracket comprises metal provided in a shape of a plate, is coupled to an inner side of the outer case, and is supported by the thermal insulating material formed in the heat insulation space. 5. The refrigerator of claim 1, wherein a plurality of shelves are disposed on the upper portion of the cooling compartment which is opened and closed by the upper door, and a plurality of drawers are disposed over the lower portion of the cooling compartment which is opened and closed by the lower door. 6. The refrigerator of claim 5, wherein a front surface of each of the drawers is disposed to be adjacent to a rear surface of the lower door in a state that the lower door is closed. 7. The refrigerator of claim 5, wherein a hinge bracket accommodating part is formed in the outer surface of the outer case while being recessed from the outer surface to the inner surface of the outer case. 8. The refrigerator of claim 7, further comprising a hinge bracket cover configured to be coupled to the outer surface of the outer case such that the hinge bracket accommodating part is covered, and an outer surface of the hinge bracket cover is coplanar with the outer surface of the outer case. 9. A refrigerator comprising: a cabinet comprising storage compartments divided by a vertical partition wall, an outer case, an inner case disposed inside the outer case to form the storage compartments, and thermal insulating material filled in a heat insulation space between the outer case and the inner case;an upper door and a lower door that are rotatably installed on the cabinet to independently open and close an upper portion and a lower portion of one of the storage compartments while dividing the one storage compartment into the upper portion and the lower portion, the one storage compartment being configured not to have any horizontal partition wall;a pillar unit rotatably installed at a lower edge of the upper door to seal a gap between the upper door and the lower door;a hinge bracket provided between the upper door and the lower door and coupled directly to the outer case with a connecting member to rotatably support a lower end of the upper door and an upper end of the lower door; anda reinforcing bracket installed onto an inner side of a wall forming the heat insulation space and coupled to the connecting member such that rigidity of the hinge bracket is reinforced,wherein the hinge bracket comprises a lateral side plate, which is supported by a lateral side of the cabinet, a front side plate, which bentedly extends from the lateral side plate and supported by a front side of the cabinet, and a hinge plate, which extends from the front side plate forward and has an upper hinge pin and a lower hinge pin axially coupled to the upper door and the lower door, respectively, andwherein the reinforcing bracket comprises a lateral side support part, which is supported by an inner side of the outer case corresponding to the lateral side plate and is coupled to the connecting member, and a front side support part, which bentedly extends from the lateral side support part and is coupled to a connecting member coupled to the front side plate, so that both of the hinge bracket and the reinforcing bracket are coupled to the lateral side and the front side of the cabinet. 10.
