Refrigerator with instant ice maker

Abstract

The present invention relates to a refrigerator having an instant ice maker, and according to an aspect of the present invention, there is provided a refrigerator including a refrigerator body provided with a freezing chamber and a refrigerating chamber; a first and a second ice maker disposed inside the refrigerator, respectively; a water supply means configured to supply water to the first and the second ice maker; and a precooling means provided between the first ice maker and the water supply means to precool water supplied to the first ice maker.

1 . A refrigerator, comprising:
 a refrigerator body provided with a freezing chamber and a refrigerating chamber;   a first and a second ice maker disposed inside the refrigerator, respectively;   a water supply means configured to supply water to the first and the second ice maker; and   a precooling means provided between the first ice maker and the water supply means to precool water supplied to the first ice maker.   
     
     
         2 . The refrigerator of  claim 1 , wherein the first ice maker is supplied with cool air by an evaporator other than an evaporator for cooling the inside of the refrigerator. 
     
     
         3 . The refrigerator of  claim 1 , wherein the freezing chamber is disposed at a lower portion of the refrigerating chamber, and
 the first ice maker is disposed in the refrigerating chamber, and the second ice maker in the freezing chamber, respectively.   
     
     
         4 . The refrigerator of  claim 3 , wherein an ice making chamber thermally isolated from the inside of the refrigerating chamber is provided at the refrigerating chamber, and the first ice maker is provided inside the ice making chamber. 
     
     
         5 . The refrigerator of  claim 4 , wherein the ice making chamber is provided at a refrigerating chamber side door for opening or closing the refrigerating chamber. 
     
     
         6 . The refrigerator of  claim 4 , wherein the ice making chamber is separated from the refrigerating chamber side door for opening or closing the refrigerating chamber to be provided inside the refrigerating chamber. 
     
     
         7 . The refrigerator of  claim 1 , wherein the precooling means comprises:
 a water supply pipe disposed to be brought into contact with an outer circumferential surface of the refrigerant pipe through which low-temperature refrigerant flows, and   water passed through the water supply pipe is cooled by being heat-exchanged with refrigerant.   
     
     
         8 . The refrigerator of  claim 4 , wherein the precooling means comprises:
 a cold storage means configured to store cool air from the cool air inside the ice making chamber; and   a water supply pipe disposed to be brought into contact with an outer circumferential surface of the cold storage means.   
     
     
         9 . The refrigerator of  claim 4 , wherein the precooling means comprises a super cooling means for storing the supplied water. 
     
     
         10 . The refrigerator of  claim 9 , wherein the super cooling means comprises:
 a container configured to store the supplied water; and   an electric field applying means configured to form an electric field in water stored inside the container.
