ABSTRACT:
A freezing refrigerator has a freezing box with side plates, top and bottom plates, and a back plate. Foodstuff products may be stored in the freezing box. The top, bottom and back plates are made of thermal conductive material. First and second envelopes are provided around the outer surfaces of the top and bottom plates. The top plate is cooled at a lower temperature by at least 5.degree. C. than the bottom plate. A heater is disposed on the outer surfaces of the top and bottom plates for purpose of melting the frost intensively produced on the inner surface of the top plate. The outer surfaces of the top and bottom plates have hydrophilic and smooth surfaces. The outer surface of the top plate is slanted downwardly toward the back plate with an inclination at approximately 10.degree. with respect to the horizontal surface. The defrosted water flows down along the outer surface. The outer surface of the top and back plates are provided with a receptacle for collecting water drops. The collected water is guided into the drain tube continuous to the outside of the freezing chamber.
