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 |
