Ice maker and refrigerator

Abstract

An ice maker includes an upper assembly provided with an upper tray which has an upper chamber recessed upwardly to define an upper side of an ice chamber in which water is filled to generate ice, a lower assembly provided with a lower tray which has a lower chamber recessed downwardly to define a lower side of the ice chamber, and a lower supporter which supports a lower side of the lower tray, in which the lower assembly is rotatably connected to the upper assembly. The ice maker also includes an upper ejector provided with an upper ejecting pin which separates ice from the upper tray after ice-making is completed, in which the upper ejector is connected to the lower assembly to be interlocked with each other, such that when the lower assembly is rotated, the upper ejector is lifted and lowered.

What is claimed is: 
     
         1 . An ice maker comprising:
 an upper assembly comprising:
 an upper tray, the upper tray defining a plurality of upper chambers that are recessed upward to form an upper portion of an ice chamber, wherein the ice chamber is configured to be filled with water to make ice therein, 
 an upper supporter that is in contact with a first surface of the upper tray to support the first surface, and 
 an upper case that is in contact with a second surface of the upper tray and is coupled to the upper supporter; 
   a lower assembly comprising:
 a lower tray, the lower tray defining a plurality of lower chambers that are recessed downward to form a lower portion of the ice chamber, 
 a lower supporter that supports a lower side of the lower tray, and 
 a lower case that at least partially covers an upper side of the lower tray, wherein the lower assembly is rotatably connected to the upper assembly; and 
   an upper ejector having an upper ejecting pin configured to separate ice in the ice chamber from the upper tray,   wherein the upper ejector is movably coupled to the lower assembly and configured to be moved up and down based on rotation of the lower assembly.
