Cold air guide structure for ice-making chamber in cold chamber door

摘要

The present invention relates to a cold air guide structure of an ice-making chamber (130a) of a cold chamber door (103). The structure including: the cold chamber door (103); an insulation case (132) disposed inside of the cold chamber door (103), thermally insulated and having an ice-making chamber (130a) therein; an ice-making unit (130) installed in the ice-making chamber (130a) of the insulation case (132), for icing a supplied water by an ice-making cold air and housing pieces of ice; an insulation cover (131) for opening and closing the ice-making chamber (130a) of the insulation case (132); a cold air inlet port (124) for sucking the ice-making cold air into the ice-making chamber (130a); a cold air outlet port (126) for exhausting the ice-making cold air from the ice-making chamber (130a); and an ice-making cold air guide unit (125) for guiding the ice-making cold air to a predetermined air passage to suck or exhaust the ice-making cold air into or from the ice-making chamber (132).
