In the conventional refrigerator, as shown in FIG. 1, a main body 1 in which a freezer compartment 1a and a refrigerating compartment 1b are partitioned by partition walls 2 is provided, and the freezer compartment 1a is provided on the front surface of the main body 1. And a freezing compartment door 8a and a refrigerating compartment door 8b are respectively mounted by hinge means to open and close the refrigerating compartment 1b.

In addition, a special chamber 1d for storing specific foods is formed above the refrigerator compartment 1b, and a vegetable compartment 1c is housed in the lower side of the refrigerator compartment 1b for storing and storing vegetables such as fruits. A plurality of shelves 1e for supporting foods requiring general refrigeration are detachably mounted between the vegetable chamber 1c and the specialty chamber 1d.

In addition, an evaporator 3 is installed at the rear of the freezing chamber 1a to generate cold air by the evaporation of the refrigerant, and the cold air generated in the evaporator 3 is disposed at the upper part of the evaporator 3. ) And a fan 4 for generating a blowing force by driving the fan motor 4a to be forcedly circulated to the refrigerating chamber 1b, and a duct 5a is provided on the rear surface of the freezing chamber 1a and the refrigerating chamber 1b. 5b are mounted, respectively.

In addition, a plurality of cold air outlets 7a and 7b are respectively drilled in the ducts 5a and 5b so that the cold air generated in the evaporator 3 is discharged to the freezing chamber 1a and the refrigerating chamber b. have.

In addition, in the duct 5b of the refrigerating chamber 1b, a temperature controller 6 for controlling the temperature of the refrigerating chamber 1b, and thus the amount of cool air supplied to the refrigerating chamber 1b by opening and closing the duct 5b. The damper 6a which controls this is provided.

On the other hand, the partition wall (2) is formed with a cold air return duct (5c) for guiding the return of the cold air so that the cold air circulated in the freezing chamber (1a) and the refrigerating chamber (1b) is supplied to the evaporator (3) to be re-cooled have.
