  • Patent number: 10551100
    Abstract: A refrigerator including a water intake container, in which carbonated water is produced by mixture of carbon dioxide and clean water, a first dispenser assembly, which the water intake container is attached to or detached from, and which supplies carbon dioxide and clean water to the water intake container when the water intake container is attached to the first dispenser, a dispenser lever and a second dispenser assembly which discharges clean water or ice according to manipulation of the dispenser lever, but stops the discharging of clean water or ice if the water intake container is attached to the first dispenser assembly. The refrigerator may include a dispenser lever and a processor to control an ice maker to stop operation if a command is entered through a user interface and to control the ice maker to start operation if the dispenser lever is manipulated while the ice maker stops operation.

  • Patent number: 8930033
    Abstract: A demand response (DR) system, computer-readable medium and method are disclosed. The DR system controls a high-power-consumption load to be pre-operated or post-operated in a low-power-rate interval instead of a high-power-rate interval, and reduces an amount of power consumption required for a high-power-rate interval, resulting in reduction of power rates. In addition, limitation to household appliance operation is minimized, to greatly reduce inconvenience of a user.

  • Publication number: 20120041577
    Abstract: A refrigerator to control food storage conditions and a control method thereof include controlling temperature in the refrigerator. The control method includes determining whether time data to be used to confirm a season is stored in a storage unit, requesting a user to input time data upon determining that the time data is not stored in the storage unit, and determining whether the stored time data is to be changed upon determining that the time data is stored in the storage unit. Temperature in the refrigerator is controlled based on properties of food for each season to improve storage efficiency of food.
