Patent number: 7603869Abstract: The present invention relates to a refrigerator having a dispenser. In the present invention, the dispenser is provided in a concave portion of a door to be exposed toward a front surface of the door. A water tank is installed between a rear surface of the dispenser and a door liner defining a rear surface of the door. The water tank stores the water delivered from an external water supply source while the water in maintained at a relatively low temperature and then discharges the water to the outside through the dispenser. Furthermore, in the present invention, a nozzle, through which the water is discharged from the water tank, is directly connected to a drainpipe of the dispenser, so that users may always take out the water maintained at a constant temperature.Type: GrantFiled: November 26, 2004Date of Patent: October 20, 2009Assignee: LG Electronics Inc.Inventors: Seong-Ook Kim, Ill-Shin Kim, Si-Yeon An, Dong-Yeol Yoo, Oh-Chul Kwon, Bum-Sik Lee, Joo-Won Park

Publication number: 20090077994Abstract: Disclosed is a refrigerator having an ice bank. The refrigerator having an ice bank comprises: a rotation shaft to which a transfer unit for transferring ice pieces in the ice bank is connected, and having a coupling groove on an outer circumferential surface of the end thereof; a joint penetrated by the rotation shaft; a driving shaft connected to the joint, and transmitting a driving force of a motor to the joint; and a coupling ring coupled to the coupling groove of the rotation shaft penetrating the joint. Since the coupling ring is locked by the joint, the rotation shaft is prevented from being arbitrarily separated from the joint. The rotation shaft can be rotated in forward and backward directions. Furthermore, since the rotation shaft has a length shorter than a rotation shaft having screw threads and nuts, the motor can have a compact configuration.Type: ApplicationFiled: September 18, 2008Publication date: March 26, 2009Applicant: LG Electronics Inc.Inventors: Seong-Wook KIM, Si-Yeon An, Il-Wook Joung
