PROBLEM TO BE SOLVED: To provide a refrigerator having a short defrosting time without causing a quality problem.SOLUTION: A cover 118 is installed between a cooler 114 and a glass-tube heater 117. A member 119 for reflection and heat conduction is arranged on each of an inner wall of a cooling chamber at the portion where the cooler is located and an inner wall of a water saucer 120 located below the glass-tube heater. A heat shield 125 is installed between an exposed portion A of the inner wall of a cooling chamber and the glass-tube heater 117, the exposed portion A being located between the member for reflection and heat conduction on the inner wall of a cooling chamber and the member for reflection and heat conduction on the inner wall of a water saucer. The heat shield and the cover are formed into one piece, and thus the amount of heat of the cover radiated from the glass-tube heater is added with the amount of heat conducted from the heat shield, besides heating action of the member for reflection and heat conduction to heat the cooler, resulting in reducing a defrosting time. Further, the heat shield blocks radiant heat from the glass-tube heater to the exposed portion of the inner wall of a cooling chamber, which solves a quality problem such as softening of the exposed portion. |
