Abstract:
There is disclosed a refrigerator; a lighting device provided in the storage chamber, a first door rotatably coupled to the case to open and close the storage chamber, an auxiliary storage chamber provided in the first door, a second door, a front panel formed of a transparent material, an evaporation treatment unit evaporated on an overall back surface of the front panel to transmit lights partially, a variable transparency film attached to a back surface of the evaporation treatment unit provided in the front panel to get transparent when the power is supplied, a frame unit with an opening having a corresponding size to an opening provided in the first door, an insulation panel distant from the front panel, a power supply unit for supplying an electric power to the variable transparency film and the lighting device, a proximity sensor provided in the second door to sense a user's approaching.

Claim (Index 14):
A refrigerator comprising:\n a case that defines a first storage chamber and a second storage chamber; a first door that is rotatably coupled to the case and that is configured to open and close the first storage chamber; a second door that is rotatably coupled to the case, and that is configured to open and close the second storage chamber, and that defines a hole that penetrates the second door, the second door comprising:\n a frame unit having the hole defined therethrough, the frame unit comprising:\n a first side surface that is facing a side of the first door when the first door and the second door are closed; and \n a second side surface that is laterally opposite to the first side surface; \n \n a front panel that covers the hole of the frame unit and that is formed of a transparent material; and \n an insulation panel formed of a transparent material, the insulation panel being located behind the front panel and configured to seal the hole of the frame unit; \n a lighting device configured to illuminate an inner space of the second storage chamber so that the inner space of the second storage chamber is viewable through the hole of the frame unit from an outside of the refrigerator based on an activation state of the lighting device; a proximity sensor that is mounted on the frame unit and that is configured to detect whether a user is within a predetermined distance from the refrigerator; and at least one processor configured to operate the lighting device to selectively make viewable to the user the inner space of the second storage chamber through the hole of the frame unit based on the proximity sensor sensing that the user is within the predetermined distance from the refrigerator, wherein the proximity sensor is located closer to the first side surface of the frame unit than the second side surface of the frame unit.
