PURPOSE:To maintain excellently the deodorizing effect given by a catalyst in the circulating air by estimating the volume of circulating air in a refrigerator based on cumulative counting of the time of opening of a damper device in the refrigerating chamber and rotating forcibly a cooling fan when the volume of circulating air decreases as the ambient temperature falls. CONSTITUTION:The odor in the air that returns to a cooling chamber 7 after circulating in a refrigerating chamber 2 and cooling chamber 3 is removed by the adsorption by a catalyst 15. And if the electric power source of a refrigerator 1 is tuned ON, a compressor 17 and fan 8 start ON and OFF operation. In this case the operation time of the compressor is cumulatively counted and when this cumulative time reaches a specified value, electric current is supplied to a heater 13 and defrosting and heating of the catalyst are carried out. After this, at the time of restarting the cooling operation, the time of opening of a damper device 20 and the operation time of the-fan 8 are respectively and cumulatively counted after a certain time has passed. And when a value detected by an outdoor air temperature sensor 16 is below a specified value and the cumulative time of opening of the damper device 20 becomes below a specified value, the fan 8 is rotated forcibly for a certain time. |
