20090019866 | CONTROLLING METHOD OF ICE MAKER - A method of controlling an ice maker is provided that minimizes generation of excess water and reduces energy consumption. The method allows for uniform heat to be generated and distributed throughout the ice tray during an ice separation process. Consequently, the ice separating process may be consistently performed irrespective of the shape of the ice tray and its surroundings, thereby minimizing generation of excess water, and reducing energy consumption. | 01-22-2009 |
20090019880 | ICE MAKER AND CONTROL METHOD OF SAME - An ice maker and a controlling method thereof are provided. The system and method may prevent the overflow or splashing of water or thin ice out of an ice tray during the supply of water or when the ice maker is shaken by an external force. The ice maker may include an ice tray, and an ice tray cover that covers an open portion of the ice tray. The cover may include an opening through which water may be supplied to the ice tray, and through which ice may be discharged from the ice tray. The cover may move together with the tray, or may move separately from the tray, to facilitate these supply and discharge processes. | 01-22-2009 |
20090020681 | ICE TRAY - An ice tray is provided that prevents the overflow or splashing of water or thin ice out of the ice tray as water is supplied to the ice tray, or when the ice tray is shaken by an external force. The ice tray may include a plurality of receiving portions that receive water for freezing into ice pieces. An overflow preventing portion may extend upward from upper edges of the receiving portions to form a barrier to water flowing out of the ice tray. Alternatively, the receiving parts may be positioned within a corresponding plurality of location parts having water proofing walls extending upward therefrom to inhibit the unintentional flow of water or thin ice out of the receiving portions of the ice tray. | 01-22-2009 |
20090049858 | ICE MAKER AND REFRIGERATOR HAVING THE SAME - An ice maker and a refrigerator having the same include an ice making container which is maintained at a temperature higher than a freezing point of water. Ace core rods having the temperature lower than the freezing point are inserted into the ice making container to cause water in the container to freeze. Accordingly, water at the periphery of the ice making container remains liquid which the water surrounding the ice core rods freezes. As a result, air bubbles generated when the ice is made can be discharged from the liquid portions of the water at the outer edges of the container. This results in ice without trapped air bubbles, which allows excellent transparent ice pieces to be formed. In some embodiments, the exterior surfaces of the ice making container are maintained at a temperature lower than the freezing point of water, and thawing rods maintained at the temperature higher than the freezing point of water are inserted into the center portions of the ice making container. In this embodiment, water at the edges of the ice making container are frozen first, while the water surrounding the thawing rods remains liquid. This also allows air bubbles to escape during formation of the ice, which results in transparent ice pieces. | 02-26-2009 |
