摘要： An artificial intelligence (AI) refrigerator includes an evaporator, a freezing chamber, an ice-making unit, a cold air duct that connects the freezing chamber to the ice-making unit, a discharge unit that discharges ice, and a controller. The controller is configured to generate ice extraction information that includes an extraction time at which a user has extracted ice, and an amount of ice extracted at the extraction time, determine an ice extraction pattern based on ice extractions captured in the ice extraction information, based on the ice extraction pattern, generate an ice-making pattern that includes one or more ice-making start times and an ice-making amount corresponding to each ice-making start time, and based on the ice-making amount, adjust an amount of cold air introduced from the freezing chamber to the ice-making unit through the cold air duct to accelerate or decelerate an ice-making speed corresponding to each ice-making start time.

摘要： An appliance includes a driver to drive a load, the load requiring AC power or DC power. A power supply receives one of external AC power, back-up AC power and back-up DC power and outputs at least one of AC power or DC power to the load. An operation mode of the home appliance is one of normal operation when receiving external AC power, normal operation when receiving one of back-up AC power and back-up DC power during a power interruption, and a power save mode when receiving one of back-up AC power and back-up DC power during the power interruption. The power supplies a first power level when there is no power interruption, a second power level when there is power interruption and a third power level when there is power interruption and the power save mode is selected, where the second power level is between the first power level and the third power level. The power save mode is automatically selected when the second power level falls below a reference power level.
