step four: when the gas sensor (11) detects that the release speed of the carbon dioxide in the ripening area (1) reaches 15-20 mg/kg.h, the electric field release device (3) is closed, and the temperature in the ripening area (1) is restored to the operating temperature for operation.
10. A refrigerator with ripening function according to claim 9, characterized in that the closing time of the electric damper (10) is not less than 1-5 min.
