An ice maker, a refrigerator including the ice maker, and an ice making method are provided. The ice maker includes a tray having a predetermined length and to which water is supplied to make ice. The ice maker is configured to mechanically separate the ice from the tray by using pistons which are driven by being pressed by structures. This allows the ice maker to have a reduced size, and a small occupation area, thereby implementing a slim configuration of a refrigerator. Furthermore, since an installation height of the ice maker is lowered, a path for supplying cool air may be shortened. This may prevent loss of cool air being supplied to the ice making chamber. Since the ice maker has a simplified configuration and precise operation controls, the fabrication costs may be reduced, and inferiority of the ice maker due to malfunctions may be prevented.

1. An ice maker, comprising: a tray having an ice making space;a driving unit configured to rotate the tray; andan ice moving member linearly movable within the ice making space upon rotation of the tray to eject ice from the tray,wherein the tray comprises an ice making cylinder having an ice making space,wherein the ice moving member includes a piston slidably movable within the ice making cylinder in a longitudinal direction of the ice making cylinder, andwherein the piston comprises: a head portion slidably coupled to an inner circumferential surface of the ice making cylinder; anda rod portion coupled to the head portion and extending in a moving direction of the piston,wherein the ice moving member further comprises a connecting unit coupled to the rod portion; anda piston guide operably connected to the connecting unit for guiding movement of the connecting unit. 2. The ice maker of claim 1, wherein the tray is configured to rotate from a first position where an opening of the tray is directed upwardly, to a second position where the opening of the tray is directed downwardly. 3. The ice maker of claim 1, wherein the tray comprises a plurality of ice making cylinders each having an ice making space and connected to each other, and wherein the ice moving member is coupled to each of the ice making cylinders. 4. The ice maker of claim 3, wherein the plurality of ice making cylinders are provided with a water flow path such that the ice making spaces are communicated to each other. 5. The ice maker of claim 4, wherein a water supply unit for supplying water to the ice making cylinders is installed above at least one of the ice making cylinders. 6. The ice maker of claim 1, wherein the tray includes a hinge member located at one end of the tray, the hinge member including a passageway therein, and wherein a water supply unit is connected to the passageway of the hinge member so as to supply water to the ice making tray through the hinge member. 7. The ice maker of claim 1, wherein the piston guide is formed in an arc shape eccentric from a rotation center of the tray. 8. The ice maker of claim 1, wherein the ice making cylinder includes a sliding hole for slidably coupling the rod portion, and wherein a stopper is formed at the end of the rod portion so as to be locked by the sliding hole. 9. The ice maker of claim 1, wherein the tray comprises a plurality of ice making cylinders each having an ice making space, and wherein the ice moving member includes a plurality of pistons slidably movable within the ice making cylinders in a longitudinal direction of the ice making cylinders. 10. The ice maker of claim 9, wherein the pistons comprise: head portions slidably coupled to an inner circumferential surface of the ice making cylinders; androd portions coupled to the head portions and extending in a moving direction of the pistons,wherein the ice moving member further comprises a connecting unit coupled to the rod portions; anda piston guide operably connected to the connecting unit for guiding movement of the connecting unit. 11. An appliance, comprising: a body including an ice making chamber;an ice maker located in the ice making chamber, the ice maker including: a tray having an ice making space;a driving unit configured to rotate the tray; andan ice moving member linearly movable within the ice making space upon rotation of the tray to eject ice from the tray,wherein the body is a refrigerator body having a refrigerating chamber and a freezing chamber, and wherein the ice making chamber is located in the refrigerating chamber. 12. The appliance of claim 11, further comprising a door configured to open and close the refrigerating chamber, wherein the ice making chamber is located at the door. 13. The appliance of claim 12, further comprising a dispenser located at the refrigerator door for drawing out ice made in the ice making chamber, wherein at least a portion of the ice making chamber is located at a same height as a portion of the dispenser. 14. An ice making method, comprising: supplying water to a tray;cooling the water contained in the tray to produce an ice mass;rotating the tray; andlinearly moving an ice moving member within the tray to eject the ice mass from the tray,wherein the supplying water to the tray comprises sensing time or an amount of the water supplied to the tray, and determining whether the sensed time or water amount has reached a preset value. 15. The method of claim 14, wherein at least a portion of the rotating of the tray is performed prior to a beginning of the linearly moving of the ice moving member. 16. The method of claim 14, wherein the linearly moving of the ice moving member is performed simultaneously with the rotating of the tray.
