  • Publication number: 20100262295
    Abstract: Refrigerator control technology, in which cool air is supplied to an ice making chamber provided in a refrigerator. The refrigerator senses whether an ice storage basket is attached or detached, whether the ice storage basket is full of ice or not, and/or whether a refrigerator door is opened or closed. Based on the sensing, the refrigerator controls ice removal operations from the ice making chamber to the ice storage basket, ice dispensing operations from the ice storage basket, and/or cool air supply to the ice making chamber.
