Abstract: Provided is a refrigerator including an adiabatic space formed on an inner surface of a chilling chamber door and an ice machine disposed inside the adiabatic space, thereby enabling a more efficient usage of an inner space of the refrigerator. Also, the present invention provides a cooling air passage structure of a refrigerator for properly supplying cooling air for freezing to an inside of the refrigerator having an ice machine disposed on an inner surface of a chilling chamber door.

Abstract: Disclosed is a dispenser for a refrigerator, which enables an effective usage of the inner space of the refrigerator and enables to always provide fresh water to a user. The dispenser (50) includes: a first pipe (51) connected with a water supply source; a reservoir (52) installed inside a door of the refrigerator and connected with the first pipe (51), for temporarily storing water supplied from the water supply source; a second pipe (53) connected with the reservoir (52); and a discharging part (54) installed in the door of the refrigerator and connected with the second pipe (53), for discharging the water supplied from the reservoir (52) depending on a user's necessity.
