Further, a dispenser may be provided at the front surface of the projection 714 and form a part of the front surface appearance of the refrigerating chamber door 21.

The supply duct 751 and the discharge duct 752 may be formed to communicate with the door receiving part 72 and communicate with the refrigerating chamber 11 through an upper side of the ice making chamber 50 and a lower side of the ice making chamber 50. That is, the supply duct 751 and the discharge duct 752 may be configured to extend around the ice making chamber 50 without passing through the ice making chamber 50.

The second door 60g may be disposed in front of the first door 70, and may be rotatably mounted to the first door 70. The second door 60g may cover the door receiving portion and may be formed in the same plane as a lower portion of the first door 70 in a closed state. Further, the second door 60g may be formed above the dispenser 73. The door receiving portion 42 can be opened and closed. In a state where the second door 60g is closed, a front appearance of the refrigerator 1g may be formed.

The front surface of the second door 60g may be formed of a door panel 62 g. The door facing 62g may be formed of various materials such as glass, metal, plastic, composite materials, and the like. Further, the inside of the second door 60g may be filled with a heat insulation material 611. Accordingly, the door receiving portion 72 may be thermally insulated by the thermal insulation material 611. The cold air flowing into the door housing portion 72 is movable along the rear surface 63 of the second door 60 g.

Accordingly, the door receiving part 72 may be insulated from the rear ice making compartment 50 by the heat insulating material 713 of the first door 70, and may be insulated from the front external air by the heat insulating material 611 of the second door 60 g. The cold air supplied to the inside of the door receiving portion 72 may flow between the second door 60g and the first door 70. Further, the inside of the door receiving portion 72 may be maintained at a set temperature by the supplied cool air.
