Refrigerator and method for controlling same

Abstract

A refrigerator of the present disclosure includes a tray configured to form an ice making cell, a water supply valve configured to control the flow of water to the ice making cell, and a controller configured to control the water supply valve, in which the controller controls the water supply valve to turn off the water supply valve to stop water supply while performing water supply and turns on the water supply valve again for additional water supply after the water supply valve is turned off.

What is claimed is: 
     
         1 . A refrigerator comprising:
 an ice maker including a tray configured to form a cell having a space configured to store liquid;   a supply valve configured to control a flow of liquid into the space of the cell; and   a controller configured to control the supply valve,   wherein the controller controls the supply valve such that a first amount of liquid is supplied, the liquid supply is paused, and a second amount of liquid is supplied after the liquid supply is paused,   wherein the first amount is less than the second amount, and   wherein the first amount is less than a half of a volume of the cell.   
     
     
         2 . The refrigerator of  claim 1 , wherein after at least a portion of the first amount of the liquid has been phase-changed to ice, the second amount of liquid is supplied. 
     
     
         3 . The refrigerator of  claim 1 , wherein the second amount is greater than the half of the volume of the cell. 
     
     
         4 . The refrigerator of  claim 1 , further comprising a heater configured to supply heat to the cell in at least a section of an ice making process. 
     
     
         5 . The refrigerator of  claim 1 , further comprising a heater configured to supply heat to the cell after the second amount of liquid is supplied. 
     
     
         6 . The refrigerator of  claim 1 , wherein:
 the tray includes a first tray forming a first portion of the cell, and a second tray forming a second portion of the cell, the second tray being configured to move relative to the first tray,   the controller controls the supply valve to be opened for supply of the first and second amounts when the second tray is at a first position relative to the first tray, the first position being a position where the first and second portions are at least partially spaced apart.   
     
     
         7 . A refrigerator comprising:
 an ice maker including a tray configured to form a cell having a space configured to store liquid;   a supply valve configured to control a flow of liquid into the space of the cell; and   a controller configured to control the supply valve,   wherein the controller is configured to:
 open the supply valve to supply a first amount of liquid, 
 close the supply valve after the first amount of liquid is supplied, 
 open the supply valve to supply a second amount of liquid after at least a portion of the first amount of liquid has been phase-changed to ice, and 
 close the supply valve after the second amount of liquid is supplied, 
   wherein the first amount is less than the second amount, and   wherein the first amount is less than a half of a volume of the cell.   
     
     
         8 . The refrigerator of  claim 7 , wherein the second amount is greater than the half of the volume of the cell. 
     
     
         9 . The refrigerator of  claim 7 , further comprising a heater configured to supply heat to the cell in at least a section of an ice making process. 
     
     
         10 . The refrigerator of  claim 7 , further comprising a heater configured to supply heat to the cell after the second amount of liquid is supplied. 
     
     
         11 . The refrigerator of  claim 7 , wherein:
 the tray includes a first tray forming a first portion of the cell, and a second tray forming a second portion of the cell, the second tray being configured to move relative to the first tray,   the controller controls the supply valve to be opened for supply of the first and second amounts when the second tray is at a first position relative to the first tray, the first position being a position where the first and second portions are at least partially spaced apart.   
     
     
         12 . A refrigerator, comprising:
 an ice maker including:
 a first tray configured to form a first portion of a cell; 
 a second tray configured to form a second portion of the cell, the first and second portions configured to form a space in which liquid is phase-changed to ice; 
 a liquid supply configured to supply liquid; 
   a driver configured to move the second tray with respect to the first tray;   a supply valve configured to control a flow of supplied liquid into the space;   a controller configured to control supply valve, wherein the controller is configured to:
 move the second tray to a first position, 
 open the supply valve to supply a first amount of liquid, 
 close the supply valve after the first amount of liquid is supplied, 
 move the second tray to a second position and standby at the second position before moving to the first position, 
 move the second tray to the first position, 
 open the supply valve to supply a second amount of liquid after moving the second tray to the first position, and 
 close the supply valve after the second amount of liquid is supplied. 
   
     
     
         13 . The refrigerator of  claim 12 , wherein the first amount is less than the second amount. 
     
     
         14 . The refrigerator of  claim 12 , wherein the second amount is greater than a half of a volume of the cell. 
     
     
         15 . The refrigerator of  claim 12 , wherein after the second amount of liquid is supplied, the second amount of liquid is phase-changed to ice. 
     
     
         16 . The refrigerator of  claim 15 , further comprising a heater configured to supply heat to the cell in at least a section of an ice making process. 
     
     
         17 . The refrigerator of  claim 12 , further comprising a first tray case formed as a separate component to the first tray and configure to support the first tray. 
     
     
         18 . The refrigerator of  claim 17 , wherein the first tray case includes a first tray cover and a first tray supporter coupled to the first tray cover.
