Patent number: 7637119Abstract: In the related art refrigerator, its structure for supplying water to a dispenser and water tank was complicated. In addition, since an icemaker is installed in a refrigerating chamber of the refrigerator, there is a problem in that the water supplied into the icemaker is frozen. Furthermore, if the icemaker is installed in the freezing chamber of the refrigerator in which the refrigerating chamber is formed at a lower portion thereof and a refrigerating chamber is formed at an upper portion thereof, there is another problem in that it is difficult to control the temperature in the refrigerating chamber or ice-making capability of the icemaker is lowered. The present invention is directed to a refrigerator.Type: GrantFiled: May 8, 2008Date of Patent: December 29, 2009Assignee: LG Electronics Inc.Inventors: Ill-Shin Kim, Seon-Il Yu, Kun-Jun Seok, Yong-Chol Kwon
