Publication number: 20080174219Abstract: There is provided a refrigerator. The refrigerator includes a storage space receiving food, a door, and a dispensing apparatus. The door selectively opens and closes the storage space. The dispensing apparatus dispenses contents stored in the storage space without opening the door. The dispensing apparatus substantially protrudes from an outer surface of the door. According to the refrigerator, since the internal structure of the door is simplified, fabrication of the refrigerator becomes easy. In addition, the internal space of the refrigerator is enlarged and a user can use a container of various sizes and shapes. Furthermore, the thickness of the door is prevented from becoming thin, thereby reducing a heat loss in the refrigerator.Type: ApplicationFiled: January 8, 2008Publication date: July 24, 2008Applicant: LG ELECTRONICS INC.Inventors: Seong Jae KIM, Hyeong Kook LEE, Kyung Han JEONG
