20090248205 | CONTROLLING METHOD FOR DRIVING A DRAWER OF A REFRIGERATOR - A movement structure for a drawer of a refrigerator is provided. The movement structure may a storage box to be automatically withdrawn from or inserted into a storage compartment of the refrigerator by pressing a button. This automatic movement of the storage box may allow the storage box to be easily withdrawn from and inserted into the storage compartment regardless of a weight of items stored in the storage box. | 10-01-2009 |
20090248207 | SYSTEM AND METHOD FOR DRIVING A DRAWER IN A REFRIGERATOR - A system and method for driving a drawer of a refrigerator are provided. This system allows a drawer to be automatically withdrawn from and/or inserted into a main body of the refrigerator. This system also allows a drawer which has been stopped during the withdrawal process to be further withdrawn from the main body so as to complete action on a withdrawal command, or to be re-inserted into the main body, so as to reduce cool air loss. | 10-01-2009 |
20100010676 | APPARATUS AND METHOD FOR CONTROLLING DRIVING OF FAN MOTOR FOR REFRIGERATOR - Disclosed is an apparatus and a method for controlling a driving of a fan motor for a refrigerator. In a normal driving mode that a temperature of the inside of the refrigerator is higher than a predetermined temperature, the fan motor is driven in a normal speed, and in a waiting mode that the temperature of the inside of the refrigerator is lower than the predetermined temperature, the fan motor is driven in a driving speed very lower than that of the normal driving mode, without stopping of the fan motor, accordingly it is capable of preventing moisture introduced into the fan motor from being frozen, thereby preventing the fan motor from being locked. | 01-14-2010 |
