20120180504 | ICEMAKER AND REFRIGERATOR HAVING THE SAME - A refrigerator has an icemaker that includes a partition arm extending from the outside of the ice making tray into the ice making tray, the partition arm constituting a part of an ice compartment structure to define ice making cells. When the ice making tray is rotated in a given direction, the ice making tray allows ice to be separated from the ice making cells by being twisted by the partition arm. When the ice making tray is rotated in an opposite direction, the ice making tray allows the ice still present in the ice making cells to fall from the ice making cells by interference with a rotation stopper formed at the partition arm. | 07-19-2012 |
20130091887 | REFRIGERATOR AND INTEGRATED RELAY MODULE OF COMPRESSOR FOR THE SAME - A relay module includes a case forming an exterior of the relay module, a Positive Temperature Coefficient (PTC) device configured to control the supply of power to the compressor, a holder mounted at the case and configured to accommodate the PTC device, a start capacitor electrically connected to the PTC device, a first connecting terminal having a first PTC connecting terminal connected to the PTC device and a first capacitor connecting terminal connected to the start capacitor, and a second connecting terminal having a second PTC connecting terminal connected to the PTC device and a second capacitor connecting terminal connected to the start capacitor. The first capacitor connecting terminal and the second capacitor connecting terminal are spaced apart a predetermined distance from a bottom surface of the case. | 04-18-2013 |
20130174599 | REFRIGERATOR - A locking apparatus of an ice bucket of a refrigerator capable of simplifying the structure of the ice bucket while preventing the cool air of the ice making compartment from leaking and the ice bucket from being shaken, the refrigerator including a locking apparatus accommodating portion formed at a lower portion of the ice making compartment, a lever hingedly coupled to the locking apparatus accommodating portion, and an elastic member configured to elastically bias the lever, wherein the lever is configured to interfere with a locking projection of the ice bucket, and a button portion configured to adjust the position of the locking protrusion by rotating the lever, wherein a gasket mounting portion formed around an opening portion of the ice making compartment is formed to be extended to the inner side of the ice making compartment to make contact with the gasket mounting portion in a two-area contact manner. | 07-11-2013 |
20130327076 | REFRIGERATOR - A refrigerator including an icemaker and an ice bucket provided at a door, a feeding unit to feed ice cubes stored in the ice bucket, a driving motor provided at a main body to drive the feeding unit, and a coupling device to transmit driving force from the driving motor to the feeding unit. When the door is closed, the driving motor is connected to the feeding unit. When the door is opened, the driving motor is disconnected from the feeding unit. Accordingly, the door has a simple structure, the ice bucket has an increased capacity, repair or replacement of the driving motor is easily achieved. The coupling device includes a first coupling unit and a second coupling unit which is engaged with the first coupling unit to receive driving force. The coupling device is configured to hide the coupling units when the door is opened. | 12-12-2013 |
