A DEVICE FOR PREVENTING A DOOR-COOLING PART FROM FREEZING IN A REFRIGERATOR WITH A DOOR-FREEZER

摘要

The present invention relates to a device for preventing the freezing of the door cooling unit of a door ice compartment refrigerator, and a cold air circulation for forcibly circulating the air around the tip of the cold air supply duct (Dp) and the cold air reduction duct (Dr) exposed to the cold compartment with the air of the cold compartment. A temperature sensor 20 for measuring the temperature of the inner wall of the refrigerating chamber R through which the fan 10, the cold air supply duct Dp and the cold air reduction duct Dr pass, and the temperature from the temperature sensor 20. It is composed of a control unit for receiving data to control the operation of the cold air circulation fan (10).;According to the present invention, by circulating cold air around the outside of the door cooling unit by forced convection, heat exchange with the refrigerating chamber can be quickly performed, preventing freezing, preventing damage caused by freezing and hardening of the door cooling unit, and door cooling. The airtightness of the door can be prevented from being lowered by maintaining the airtightness of the door, and the door cooling part can be thickened by the ice to prevent the door of the refrigerator from being incompletely closed.;Refrigerator, De-icing, Door, Freezing, Cold Circulation Fan
