Open the freezer return cold air path 12 and
The cold air passage opening / closing plate 16 is opened, the cold air outlet 20 is opened to coincide with the opening 19c, and the cool air generated by the evaporator 7 is cooled by the blower fan 9 into the refrigerator compartment 3 and the freezer compartment 4. After being sent to the vegetable compartment 5 and cooling the inside of the refrigerator, it returns to the lower part of the evaporator 7 through the freezing compartment return cold air passage 12 and the vegetable compartment return cold air passage 13 as return cold air. At the time of defrosting, the slide plate 19 slides downward, the bypass duct 14 is opened by the bypass duct opening / closing plate 15, the freezing room return cold air path 12 is closed, and the delivery cold air path 10 is opened and closed by the cold air path. Closed by the plate 16, the cold air outlet 20 is shifted from the opening 19c and closed, a compressor (not shown) is stopped, the cooling of the evaporator 7 is stopped, and the defrost heater 8 is heated. The heated air heated by the defrost heater 8 is recirculated to the lower portion of the evaporator 7 through the bypass duct 14 by the blower fan 9 after heating and defrosting the evaporator 7. Since the heated air is strongly stirred by forced convection as described above, the evaporator 7 can be uniformly heated and defrosted. Further, since the cold air path 12, the cold air path 10, and the cold air outlet 20 are closed, the heated air does not leak into the refrigerator.
