The present invention relates to an air curtain socket elbow for a drain of a freezing/refrigerating device and, more specifically, to a structure installed in the drain of the freezing/refrigerating device and preventing an inflow of external air inside the freezing/refrigerating device while discharging condensate. The air curtain socket elbow for a drain of a freezing/refrigerating device can reduce installation costs by simplifying the structure of a drain device and obtain excellent economic efficiency by preventing frost generated in the past. The air curtain socket elbow includes a case (10) connected to the drain pipe (2) and discharging the condensate to the outside; a blocking film (20) including connecting protrusions (23) on both sides to be installed inside the case (10) and preventing an inflow of external air while passing through the condensate sent to the case (10) by rotating while both sides are bent around the connecting protrusions (23); and a weight (30) formed on one side of the blocking film (20) and enabling the blocking film (20) to always close the case (10) by the weight. |
