  • FIG. 2 and is described below by using specific steps.
  • Step S101 Refrigeration starts.
  • a temperature sensor for detecting a storage temperature of a compartment may be disposed in the compartment, and a storage temperature obtained through detection is fed back to a control unit of the refrigerator. If a current storage temperature is higher than a setting temperature of the compartment, the control unit of the refrigerator starts to perform refrigeration in the compartment accordingly.
  • Step SI 02. A compressor and a fan start to work.
  • the compressor of the refrigerator starts to work
  • a condenser and a condenser fan also start to work
  • an evaporator fan working for the compartment also works, to blast cold air cooled by an evaporator to be blown into the compartment, to decrease the storage temperature of the compartment.
  • Step SI 03. Compare whether the storage temperature is less than or equal to the setting temperature.
  • Whether to stop refrigeration and to adjust a rotating speed of the fan is determined by a comparison result between the storage temperature obtained through real-time detection and the setting temperature of the compartment.
  • step SI 04 When the storage temperature obtained through detection is less than or equal to the setting temperature of the compartment, the compartment has no more need of refrigeration, directly enter step SI 04 in which the compressor and the fan stops working, and step 105 in which the refrigeration ends.
  • the compartment needs to continue refrigerating, and enter step SI 06 for further determining.
  • Step SI 06. Determine whether the storage temperature changes.
  • step SI 03 When the storage temperature obtained through detection keeps unchanged, it indicates that in this case, cold energy supplied for the compartment is suitable, the rotating speed of the fan may keep unchanged, and in this case, jump back to step SI 03 to continue determining.
  • step SI 07 When the storage temperature obtained through detection change, it indicates that in this case, cold energy supplied for the compartment needs to be adjusted, so as to enter step SI 07 to adjust the rotating speed of the fan, and then jump back to SI 03 again to continue determining.
  • Step SI 07. Adjust the rotating speed of the fan.
  • the rotating speed of the fan is positively correlated with a storage temperature obtained through current detection. If the storage temperature obtained through the current detection is higher than a storage temperature obtained through last detection, it indicates that in this case, the cold energy supplied for the compartment needs to be increased, and the rotating speed of the fan may be correspondingly adjusted to be higher. If the storage temperature obtained through the current detection is lower than the storage temperature obtained through the last detection, it indicates that in this case, the cold energy supplied for the compartment needs to be decreased, and the rotating speed of the fan may be correspondingly adjusted to be lower.

Abstract

La présente invention concerne un procédé de commande destiné à un appareil frigorifique ménager (100). Le procédé de commande consiste : à faire fonctionner un compresseur (4) et un ventilateur (61, 81) afin de refroidir un espace de stockage, et à régler une vitesse de rotation du ventilateur (61, 81) conjointement avec une température de l'espace de stockage, ou à régler la vitesse de rotation du ventilateur (61, 81) conjointement avec une vitesse de rotation du compresseur (4). De cette manière, pendant la réfrigération dans l'espace de stockage, conjointement avec une variation de la température de l'espace de stockage, le besoin d'énergie froide de l'espace de stockage varie également, et, de la même façon, la vitesse de rotation du compresseur (4) peut aussi varier, de façon à régler la vitesse de rotation du ventilateur (61, 81) en fonction d'une variation de la vitesse de rotation du compresseur (4), amenant ainsi la vitesse de rotation du ventilateur (61, 81) à correspondre essentiellement au besoin d'énergie froide de l'espace de stockage en temps réel.
