20110083749 | METHOD FOR CONTROLLING WATER SUPPLY AMOUNT AND REFRIGERATOR USING THE SAME - A method for controlling a water supply amount and a refrigerator using the same are disclosed. The method includes receiving information regarding a water supply amount selected by a user, counting a duration after starting water supply, and checking whether an error in a water supply amount measurement unit exists. When the water supply amount measurement unit is normal, an actual water supply amount is determined based on a signal from the water supply amount measurement unit, and, when a fault exists, a water supply amount is determined based on correlation between a stored water supply amount for normal operation and a water supply duration. Water supply is stopped when the selected water supply amount and the determined water supply amount are equal. When the water supply amount measurement unit is normal, the signal from the water supply amount measurement unit and information regarding a water supply duration are stored. | 04-14-2011 |
20120000216 | ICE MAKER OF REFRIGERATOR AND POWER SAVING METHOD OF ICE MAKER - An ice maker for a refrigerator and a power saving method of an ice maker are provided. The ice maker includes: an ice tray for making ice; an ejector for removing the ice from the ice tray; an storage unit for dispensing and storing the removed ice; and a controller for controlling an ice making operation for making ice, an ice removing operation for removing generated ice, and a dispensing operation of dispensing removed ice, and providing control to cut off power supply during the ice making operation. While an ice making operation is being performed, an ice making elapsed-time and an ice making temperature are measured to determine whether or not the ice making operation has been completed, and while the ice making operation is being performed, power supplied to the ice maker is cut off, thus reducing unnecessary power consumption. | 01-05-2012 |
20120023980 | REFRIGERATOR AND CONTROLLING METHOD OF THE SAME - Disclosed are a refrigerator and a controlling method of the same. A change amount of a refrigerating chamber temperature, or a change amount of a freezing chamber temperature may be calculated per time period, and a load corresponding driving may be executed based on the calculated change amount. This may allow the load corresponding driving to be executed more precisely, reduce power consumption, and enhance stability and efficiency of a system. | 02-02-2012 |
20120023981 | REFRIGERATOR AND DRIVING METHOD THEREOF - A refrigerator and a driving method thereof are disclosed. The number of vibration of each compressor, evaporation temperature of each evaporator, or an open time of a refrigerant switching valve is detected to determine whether the flow of refrigerant is biased so as to adjust a cooling capability of the compressor or an open value or open time of a refrigerant switching valve, thereby uniformly distributing the refrigerant into first and second evaporators. Accordingly, the refrigerator can be driven with an independent refrigeration cycle corresponding to a load of a freezing chamber or a refrigerating chamber, resulting in reduction of unnecessary power consumption of the refrigerator. | 02-02-2012 |
20120302167 | MOBILE TERMINAL - A mobile terminal including a wireless communication unit configured to wirelessly communicate with at least one other terminal; a touch screen; an input unit configured to generate input data; and a controller configured to activate a handwriting input function in response to the input data generated by the input unit, capture an image of a display screen being displayed on the touch screen, receive handwriting input received through the touch screen, generate output data corresponding to the received handwriting input, and generate a file including the generated output data and the captured image of the display screen. | 11-29-2012 |
20120312034 | REFRIGERATING CYCLE APPARATUS AND METHOD FOR OPERATING THE SAME - A refrigerating cycle apparatus and a method of operating the same are provided. For a refrigerating cycle having a plurality of compressors connected in series for multi-stage compression, an inner space of each compressor and a pipe of the refrigerating cycle may be connected via an oil collection pipe, and oil may be discharged into the refrigerating cycle by pressure reversal during a pressure balancing operation, so as to allow the discharged oil to be collected into a high-stage compressor or a low-stage compressor. Accordingly, an amount of oil may be uniformly maintained in each of the plurality of compressors to prevent losses due to friction and/or increases in power consumption due to a lack of oil in one or more of the compressors. The structure of a device and pipes for performing oil balancing between the compressors may be simplified to enhance efficiency of the compressors. | 12-13-2012 |
20130042638 | REFRIGERATOR AND CONTROLLING METHOD THEREOF - The refrigerator of the present invention comprises: a refrigeration cycle composed of a compressor, a condenser and an expansion unit; an evaporator for evaporating a refrigerant which passes through the expansion unit; a heating unit for providing the heat for defrosting the evaporator; and a frost sensor unit which is provided at one side of the evaporator for sensing the amount of frost on the evaporator, and is characterized in that an operation of the frost sensor unit is started on the basis of whether operation conditions of the frost sensor unit are recognized and the heating unit selectively generates the heat according to the sensed result of the frost sensor unit. According to one embodiment of the present invention, the amount of frost on the evaporator is easily determined by the operation of the frost sensor unit and the evaporator is effectively defrosted according to the amount of frost determined thereby. | 02-21-2013 |
20130340454 | REFRIGERATING CYCLE APPARATUS - A refrigerating cycle apparatus is provided. The refrigerating cycle apparatus may include a refrigerant switching valve, which may be moved to a predetermined position through a simple circuit structure, during a blackout (power outage). Further, in a case in which input power is cut off due to a blackout, while the refrigerating cycle apparatus operates, oil may be collected. Even if input power is cut off due to a power outage, in a state in which the refrigerant switching valve is open while a refrigerating cycle apparatus having two compressors of two stages (2tage-2comp) is operating, the refrigerant switching valve may be converted to a closed state. This may reduce a pressure difference between the two compressors, and prevent damage to the compressors. | 12-26-2013 |
