  • Step S532 Obtain a weight change rate threshold corresponding to the food material in the ripening space and used to indicate that the food material has been matured.
  • Step S534 When the weight change rate of the food material reaches the weight change rate threshold, it is determined that the food material has reached the expected state.
  • Step S536 Exit maturation.
  • the solution of the present invention can directly determine whether to exit the ripening based on the state of the food materials. This is compared with the solution that uses the ripening time to control the ripening process. , is more direct and highly accurate, effectively reduces the impact of uncertainty factors that may occur during the aging process on the aging effect, and is conducive to improving the control accuracy of the refrigerator 10 for the aging process.

Abstract

La présente invention concerne un réfrigérateur et un procédé de commande associé. Le procédé de commande consiste à : déterminer qu'un espace d'affinage commence un affinage ; obtenir un paramètre d'environnement caractéristique correspondant à une matière alimentaire dans l'espace d'affinage et utilisé pour marquer que l'affinage est achevé pour la matière alimentaire, et une valeur définie du paramètre d'environnement caractéristique ; détecter une valeur en temps réel du paramètre d'environnement caractéristique de l'espace d'affinage, et stopper l'affinage si la valeur en temps réel du paramètre d'environnement caractéristique atteint la valeur définie.
