Abstract: An ice maker of a refrigerator includes an upper assembly having an upper tray that defines upper portions of a plurality of hemispherical ice making chambers. The ice maker also includes a lower assembly located vertically below the upper assembly and configured rotate relative to the upper assembly about a rotation shaft and having lower tray that defines lower portions of the plurality of hemispherical ice making chambers. The ice maker also includes a lower ejector unit that is located vertically below the lower tray and that is configured to, based on the lower assembly rotating away from the upper assembly, push the lower tray through the lower support to thereby discharge the ice piece from the ice making chamber. The lower tray includes a deformable portion at each of the plurality of ice making chambers that is configured to be pushed by the lower ejector unit.

Abstract: An ice maker includes an upper tray and a lower tray made of an elastic material. Upper chambers in the upper tray and lower chambers in the lower tray contact each other to define spherical ice chambers, respectively. An ejector-receiving opening is opened to each of the upper chambers. An opening-defining wall extends upward along a circumference of each ejector-receiving opening. An upper ejector passes through the ejector-defining wall and vertically moves to remove ice from the ice chamber, and a driver pivots the lower tray to open and close the upper tray and the lower tray. The upper tray includes a horizontal extension forming a top face of the upper tray, and the upper chamber is positioned below the horizontal extension such that the opening-defining wall is formed at a vertical level equal to or lower than a vertical level of the opening-defining wall.
