Disclosed is a quick ice-making control method of an ice-maker for a refrigerator, in which an ejector for extracting obtained ice stirs supplied water to be frozen so as to promote thermal transmission of the water. The quick ice-making control method includes the steps of (a) supplying water into an ice-maker mold, (b) quickly freezing the water by rotating an ejector for a predetermined time after the step (a), and (c) separating the obtained ice from the ice-maker mold in case that a temperature of the ice-maker mold is lower than a predetermined temperature after the step (b).

What is claimed is: 1. An ice-making control method for an ice-maker for a refrigerator comprising: supplying water into an ice-maker mold; rotating an ejector for a first predetermined time such that the water supplied into the ice-maker mold is agitated to be frozen quickly; switching on a heater

What is claimed is: 1. An ice-making control method for an ice-maker for a refrigerator comprising: supplying water into an ice-maker mold; rotating an ejector for a first predetermined time such that the water supplied into the ice-maker mold is agitated to be frozen quickly; switching on a heater to separate an obtained ice from the ice-maker mold and then switching off the heater; rotating the ejector so that the obtained ice is ejected from the ice-maker mold; and returning the ejector to an initial position. 2. The ice-making control method as set forth in claim 1, wherein, in rotating an ejector for a first predetermined time, the ejector is rotated within a predetermined angular range. 3. The ice-making control method as set forth in claim 2, wherein the predetermined angular range is designated such that an upper rotation limit of pins of the ejector is higher than a level of the supplied water. 4. The ice-making control method as set forth in claim 2, wherein the predetermined angular range is designated such that an upper rotation limit of pins of the ejector is lower then a level of the supplied water. 5. The ice-making control method as set forth in claim 1, wherein, in rotating an ejector for a first predetermined time, the ejector is rotated in one direction. 6. The ice-making control method as set forth in claim 1, wherein a rotational speed of the ejector when rotating an ejector for a first predetermined time is higher than that of the ejector when rotating the ejector so that the obtained ice is ejected from the ice-maker mold. 7. The ice-making control method as set forth in claim 1, wherein the heater is switched on when a temperature of the ice-maker mold is lower than a predetermined temperature, and is then switched off when a second predetermined time elapses. 8. The ice-making control method as set forth in claim 1, wherein the heater is switched on when a temperature of the ice-maker mold is lower than a first predetermined temperature, and is then switched off when the temperature of the ice-maker mold reaches a second predetermined temperature higher than the first predetermined temperature. 9. The ice-making control method as set forth in claim 1, wherein the heater is switched off when the ejector reaches a predetermined position. 10. The ice-making control method as set forth in claim 1, further comprising: sensing whether the ejected ice reaches a full ice level after rotating the ejector so that the obtained ice is ejected from the ice-maker mold, wherein subsequent to supplying water into an ice-maker mold, the method is stopped when it is determined that the ejected ice reaches a full ice level when rotating the ejector so that the obtained ice is ejected from the ice-maker mold. 11. An ice-making control method for an ice-maker for a refrigerator, comprising: supplying water into an ice-maker mold; rotating an ejector such that the water supplied into the ice-maker mold is agitated to be frozen quickly, and then stopping the rotation of the ejector when a temperature of the ice-maker mold is lower than a predetermined temperature; switching on a heater to separate an obtained ice from the ice-maker mold, and then switching off the heater; rotating the ejector so that an obtained ice is ejected from the ice-maker mold; and returning the ejector to an initial position. 12. The ice-making control method set forth in claim 11, wherein, when rotating an ejector such that the water supplied into the ice-maker mold is rotated to be frozen quickly, the ejector is rotated within a predetermined angular range. 13. The ice-making control method set forth in claim 12, wherein the predetermined angular range is designated such that an upper rotation limit of pins of the ejector is higher than a level of the supplied water. 14. The ice-making control method set forth in claim 12, wherein the predetermined angular range is designated such that an upper rotation limit of pins of the ejector is lower then a level of the supplied water. 15. The ice-making control method set forth in claim 11, wherein, when rotating an ejector such that the water supplied into the ice-maker mold is rotated to be frozen quickly, the ejector is rotated in one direction. 16. The ice-making control methods set forth in claim 11, wherein a rotational speed of the ejector, when rotating an ejector such that the water supplied into the ice-maker mold is rotated to be frozen quickly, is higher than that of the ejector when rotating the ejector so that an obtained ice is ejected from the ice-maker mold. 17. The ice-making control method as set forth in claim 11, wherein the heater is switched on when a temperature of the ice-maker mold is lower than a predetermined temperature, and is then switched off when a predetermined time elapses. 18. The ice-making control method as set forth in claim 11, wherein the heater is switched on when a temperature of the ice-maker mold is lower than a first predetermined temperature, and is then switched off when the temperature of the ice-maker mold reaches a second predetermined temperature higher than the first predetermined temperature. 19. The ice-making control method as set forth in claim 11, wherein the heater is switched off when the ejector reaches a predetermined position. 20. The ice-making control method as set forth in claim 11, further comprising: sensing whether the ejected ice reaches a full ice level after rotating the ejector so that the obtained ice is ejected from the ice-maker mold, wherein subsequent to supplying water into an ice-maker mold, the method is stopped when it is determined that the ejected ice reaches a full ice level when rotating the ejector so that the obtained ice is ejected from the ice-maker mold.
