The upper surface of the main body 11 is provided with a control unit 55 to control each drive component including a blower fan 44, etc., which will be described later, the thawing mode on the front surface of the freezer compartment 22 of the main body 11 And a thawing mode selection button 24a for selecting the light, a plurality of selection buttons 24b for selecting the operation mode of the freezer compartment 21 and the refrigerating chamber 25, and a display unit 24c for displaying the set conditions. One mode selector 23 is provided. Here, the thawing mode is formed in a plurality of modes having different thawing times, respectively, so as to select an appropriate thawing time according to the characteristics of the frozen food.

The machine chamber 31 opened rearward is formed in the rear lower region of the main body 11, and the compressor 33 for compressing the refrigerant is provided in the lower region of the internal refrigerating chamber 25 of the machine chamber 31. One side of the compressor 33 is provided with a condenser 35 for condensing the refrigerant compressed by the compressor 33 by heat radiation, one side of the condenser 35 by blowing toward the condenser 35 to dissipate the refrigerant A heat radiating fan 37 for promoting is provided.

On the other hand, the thawing chamber forming member 41 is coupled to the lower side of the refrigerating chamber 25 of the main body 11 to form a thawing chamber R _T therein, and the thawing chamber forming member 41 has a smooth heat transfer. It is formed to have a rectangular cylindrical shape with one side opened with a thermally conductive member such as aluminum (Al) or copper (Cu).

A flange portion 42a that is bent outward and extends in the circumferential direction is formed in the front opening region of the thawing chamber forming member 41, and air flows between the thawing chamber forming member 41 and the main body 11. The flow space S of air is formed so as to correspond to the projected width of the flange portion 42a. The outer surface of the thawing chamber forming member 41 is formed with a plurality of heat transfer fins 43 protruding from the surface so as to increase the surface area and to quickly perform heat transfer. Here, the heat transfer fin 43 may be configured to have a rib shape arranged in parallel with the air flow direction, it may be formed to have a rod shape.
