The present invention relates to a refrigerator and an ice maker thereof, and more particularly, to an ice maker provided in a refrigerating chamber of a refrigerator. An ice maker according to the present invention comprises a tray for storing a drinkable water to be used for making ice, an ejector for separating ice formed in the tray, an ice-making pipe provided in the tray, and a heating member provided in the tray. According to a refrigerator and an ice maker thereof according to the present invention, there is no need for forming an additional duct to supply cold air to the ice maker in order to make ice, whereby it is possible to simplify a manufacturing process of a refrigerator and to reduce manufacturing costs of a refrigerator.

The refrigerator as claimed in claim 1, wherein at least one of the refrigerant pipe or the heater is imbedded in the tray. 3. The refrigerator as claimed in claim 1, wherein at least one of the refrigerant pipe or the heater contacts the tray. 4. The refrigerator as claimed in claim 1, comprising two refrigerating chamber doors disposed laterally relative to one another. 5. The refrigerator as claimed in claim 1, wherein the tray is disposed adjacent to the cold air flow passage. 6. The refrigerator as claimed in claim 1, wherein the container has an opening at an upper portion, and at least a portion of the cold air discharged from the cold air flow passage is discharged downward to the opening of the container. 7. The refrigerator as claimed in claim 1, wherein the tray is disposed at a side of the refrigerating chamber corresponding to a position where ice falls into the container. 8. The refrigerator as claimed in claim 1, further comprising an ice dispenser disposed in the at least one refrigerating chamber door where the container is disposed. 9. The refrigerator as claimed in claim 1, further comprising an auger vertically arranged in the container. 10. A refrigerator, comprising: a main body including at least a refrigerating chamber and a freezing chamber disposed under the refrigerating chamber;at least one refrigerating chamber door to open or close the refrigerating chamber;a tray to receive water to be used for making ice, the tray disposed inside of the refrigerating chamber;a refrigerant pipe adjacent to the tray so as to freeze the water received in the tray;a heater to heat the tray;an ejector to eject ice in the tray;a motor to actuate the ejector;a container coupled to the at least one refrigerating chamber door, so that wherein an interior space of the container is exposed to communicates with an interior of the refrigerating chamber;a cold air flow passage for supplying cold air from the freezing chamber to the container to maintain ice in the container in a frozen state, wherein the cold air flow passage extends extending along a ceiling of the refrigerating chamber, and whereinone or more holes located at an end section of the cold air flow passage is the only hole or are the only holes that direct cold air into the refrigerating chamber,the cold air passage is separated from being in communication with the interior of the refrigerating chamber continuously from a first point to a second point,the first point corresponds to a point at which the cold air passage enters the refrigerating chamber and the second point corresponds to a point where the one or more holes are located, and the cold air passage includes no air intake ports in the refrigerating chamber between the first point and the second point. 11. The refrigerator as claimed in claim 10, wherein the tray is disposed adjacent to the cold air flow passage. 12. The refrigerator as claimed in claim 10, wherein the container has an opening at an upper portion, and at least a portion of the cold air discharged from the cold air flow passage is discharged downward to the opening of the container. 13. The refrigerator as claimed in claim 10, wherein the tray is disposed at a side of the refrigerating chamber corresponding to a position where ice falls into the container.
