Refrigerator

Abstract

A refrigerator may include: a storage chamber, a first ice-maker, a second ice-maker, a cooler for supplying the cold to the storage chamber and the ice-making chamber, an ice bin for storing ice generated by the second ice-maker, a water supply unit for supplying water to the ice-making cell, a heater for supplying heat to the ice-making cell, and a controller for controlling the heater. The controller may increase the heating amount of the heater when the heat transfer amount between the cold in the storage chamber and the water in the ice-making cell is increased, and decreases the heating amount of the heater when the heat transfer amount between the cold in the storage chamber and the water in the ice-making cell is reduced.

What is claimed is: 
     
         1 . A refrigerator comprising:
 a first ice maker comprising a tray assembly to define a cell that forms a space in which a liquid is to phase-change into ice;   a second ice maker disposed in an ice making compartment;   an ice bin configured to store ice provided by the second ice maker;   a cooler disposed in the refrigerator; and   a heater configured to supply heat into the cell,   wherein at least one of the cooler or the heater is controlled such that   at least one of an amount of cold supply of the cooler or a heating amount of the heater when full ice of the ice bin is detected is different from at least one of an amount of cold supply of the cooler or a heating amount of the heater when the full ice of the ice bin is not detected.   
     
     
         2 . The refrigerator of  claim 1 , wherein a temperature of the cold supplied to the storage chamber when the full ice of the ice bin is not detected is lower than a temperature of the cold supplied to the storage chamber when the full ice of the ice bin is detected. 
     
     
         3 . The refrigerator of  claim 1 , wherein a temperature of the cold supplied to the ice making compartment when the full ice of the ice bin is not detected is lower than a temperature of the cold supplied to the ice making compartment when the full ice of the ice bin is detected. 
     
     
         4 . The refrigerator of  claim 1 , wherein, when the full ice of the ice bin is not detected after the full ice of the ice bin is detected, the amount of cold supply of the cooler for the storage chamber increases. 
     
     
         5 . The refrigerator of  claim 1 , wherein, the full ice of the ice bin is detected after the full ice of the ice bin is not detected, the amount of cold supply of the cooler for the storage chamber decreases. 
     
     
         6 . The refrigerator of  claim 1 , wherein the amount of cold supply of the cooler when the full ice of the ice bin is not detected is greater than the amount of cold supply of the cooler when the full ice of the ice bin is detected. 
     
     
         7 . The refrigerator of  claim 1 , wherein the heating amount of the heater increases when the amount of cold supply of the cooler increases, or
 the heating amount of the heater decreases when the amount of cold supply of the cooler decreases.   
     
     
         8 . The refrigerator of  claim 1 , wherein the amount of cold supply to the ice making compartment when the full ice of the ice bin is detected is less than the amount of cold supply to the ice making compartment when the full ice of the ice bin is not detected. 
     
     
         9 . The refrigerator of  claim 1 , wherein the amount of cold supply of the cooler when the full ice of the ice bin is not detected is less than the amount of cold supply to the ice making compartment when the full ice of the ice bin is detected. 
     
     
         10 . The refrigerator of  claim 9 , wherein the heating amount of the heater when the full ice of the ice bin is detected is greater than the heating amount of the heater when the full ice of the ice bin is not detected. 
     
     
         11 . The refrigerator of  claim 9 , wherein, when the full ice of the second ice bin is detected, the heating amount of the heater increases. 
     
     
         12 . The refrigerator of  claim 9 , wherein, when the full ice of the second ice bin is not detected, the heating amount of the heater decreases. 
     
     
         13 . The refrigerator of  claim 1 , wherein the cooler includes at least one of an evaporator or a thermoelectric element. 
     
     
         14 . The refrigerator of  claim 1 , wherein the heating amount of the heater when the full ice of the ice bin is not detected is greater than the heating amount of the heater when the full ice of the ice bin is detected. 
     
     
         15 . The refrigerator of  claim 1 , wherein the cooler is configured to supply cold to a storage chamber where the first ice maker is positioned. 
     
     
         16 . The refrigerator of  claim 15 , wherein the ice making compartment is partitioned from the storage chamber. 
     
     
         17 . The refrigerator of  claim 1 , further comprising a door where the ice making compartment is provided. 
     
     
         18 . The refrigerator of  claim 1 , further comprising a first storage chamber, and a second storage chamber partitioned from the first storage chamber,
 wherein the first ice maker is provided in the first storage chamber, and the second ice maker is provided in the second storage chamber.   
     
     
         19 . The refrigerator of  claim 1 , wherein the second ice maker makes ice having the same shape as the first ice maker, or
 the second ice maker makes ice having a different shape from the first ice maker.   
     
     
         20 . The refrigerator of  claim 1 , wherein the heater is configured to be turned on at least partial section while the cooler supplies cold.
