Ice making device and refrigerator

Abstract

A refrigerator according to the present embodiment may include a storage compartment in which articles are stored. The refrigerator may further include a cooler for supplying cold to the storage compartment. The refrigerator may further include a first tray portion forming a portion of an ice-making cell, which is a space in which water is phase-changed into ice by the cold. The refrigerator may further include a second tray portion which forms another portion of the ice-making cell and is disposed to be in contact with the first tray portion during an ice-making process and to be spaced apart from the first tray portion during an ice-separating process. The refrigerator may further include a water supply portion for supplying water to the ice-making cell. The refrigerator may further include a controller controlling the supply of cold to the storage compartment. The refrigerator may further include a pusher spaced apart from the second tray portion by a predetermined distance.

1 . A refrigerator comprising:
 a storage chamber where an item is stored;   a cooler configured to supply cold to the storage chamber;   a second one tray that defines a portion of a cell that is a space in which liquid is phase-changed into ice by the cold;   a second another tray that defines another portion of the cell and arranged to be in contact with the second one tray during an ice making process and to be spaced apart from the second one tray during an ice separation process;   a sub liquid suppler configured to supply liquid to the cell;   and   a pusher spaced apart from the second another tray by a predetermined distance.   
     
     
         2 . The refrigerator of  claim 1 ,
 wherein at least a portion of the sub liquid suppler is movably provided to be located at different positions during the ice making process and the ice separation process.   
     
     
         3 . The refrigerator of  claim 2 , wherein the second another tray moves to an ice separation position in a first direction to take out the ice from the cell after an ice making in the cell is completed and then second another tray moves in a second direction. 
     
     
         4 . The refrigerator of  claim 3 ,
 wherein the first direction is different from the second direction.   
     
     
         5 . The refrigerator of  claim 4 ,
 wherein the first direction is a direction opposite to the second direction.   
     
     
         6 . The refrigerator of  claim 1 ,
 wherein at least a portion of the sub liquid suppler is disposed at one side of the second another tray.   
     
     
         7 . The refrigerator of  claim 6 ,
 wherein the sub liquid suppler comprises:   a first through hole through which liquid is introduced,   a second through hole through which liquid is discharged, and   a pipe connecting the first through hole and the second through hole.   
     
     
         8 . The refrigerator of  claim 7 ,
 wherein the second through hole is arranged to supply liquid into the ice making cell through an opening formed at one side of the second another tray.   
     
     
         9 . The refrigerator of  claim 7 ,
 wherein the second through hole is movably provided to be located at different positions during the ice making process and the ice separation process.   
     
     
         10 . The refrigerator of  claim 7 ,
 wherein the second through hole is provided so that a position of the second through hole changes while the second another tray moves.   
     
     
         11 . The refrigerator of  claim 7 ,
 wherein while the second another tray moves in a first direction, the second through hole moves in the first direction, or   while the second another tray moves in a second direction, the second through hole moves in the second direction.   
     
     
         12 . (canceled) 
     
     
         13 . A refrigerator comprising:
 a second one tray that defines a portion of a cell that is a space in which liquid is phase-changed into ice by cold;   a second another tray that defines another portion of the cell and arranged to be in contact with the second one tray during an ice making process and to be spaced apart from the second one tray during an ice separation process;   a sub liquid suppler configured to supply liquid to the cell;   and   a pusher spaced apart from the second another tray by a predetermined distance,   wherein the pusher provides a path for a component to move.   
     
     
         14 . The refrigerator of  claim 13 ,
 wherein the pusher is disposed at one side of the second another tray.   
     
     
         15 . The refrigerator of  claim 14 ,
 wherein the pusher comprises a through hole that allows the component to move through an interior.   
     
     
         16 . The refrigerator of  claim 15 ,
 wherein the through hole comprises a first through hole for the component to enter an inside of the pusher; and   a hollow space provided for the component passing through the first through hole to pass through an inside of the pusher.   
     
     
         17 . The refrigerator of  claim 16 ,
 wherein the through hole comprises a second through hole that provides a position at which the component passing through the hollow space stops, or   the pusher comprises a wall that provides a position at which the component passing through the hollow space stops.   
     
     
         18 . (canceled) 
     
     
         19 . The refrigerator of  claim 15 ,
 wherein the pusher comprises an opening formed therein so that the component moves therethrough.
