Claims (56)

1. A refrigerator comprising:

a body having an open front;

a refrigerator door configured to shield the open front of the body;

an ice storage provided on the refrigerator door to store ice;

an ice-making chamber provided in the body to produce the ice;

an ice maker disposed in the ice-making chamber to transfer the produced ice to the ice storage;

a power receiver provided at the ice maker to receive wireless power; and

a power transmitter disposed on one side of one of the body and the ice-making chamber to transmit wireless power to the power receiver.

2. The refrigerator of claim 1 , wherein the ice maker includes

an ice-making tray configured to store water for making ice;
