摘要： A damper for refrigerators is disclosed. The damper of this invention effectively vaporizes moisture drops, condensed on a higher temperature surface of a damper's baffle due to a dewing phenomenon caused by a difference in temperature between opposite surfaces of the baffle, thus allowing the baffle to be almost free from freezing. In order to expose the moisture drops on the higher temperature surface of the baffle to cool air flowing through the cool air passage for the fresh compartment when the baffle is opened, the baffle is rotatably held by a rotating shaft installed on the central portion of the baffle or by a hinge pin spaced apart from the baffle by a distance. In the damper of this invention, the moisture drops, condensed on the higher temperature surface of the baffle due to a temperature difference between opposite surfaces of the baffle while the baffle is closed, are fully exposed to the dry cool air when the baffle is opened, and so it is possible for the moisture drops to be quickly evaporated and absorbed by the cool air. The damper of this invention thus effectively prevents its baffle from freezing due to the condensed moisture drops and allows the baffle to be smoothly operated without failure, and improves the operational reliability and market competitiveness of the refrigerators.
