Abstract
A refrigerator with an ice dispenser includes a spiral type time delay unit for controlling the opening and closing of an ice duct. A duct cap opens and closes an ice duct formed in the refrigerator. A rotating shaft of the time delay unit is operably connected to the duct cap. Foldaway catching members on a rotating shaft intersect with a threaded cylindrical body. The catching members fold back to allow a quick opening of the ice duct. The catching members then interact with the threaded cylindrical body as the ice duct closes to delay the closing process.
