Abstract

La présente invention concerne un procédé de commande d'une machine à glaçons. La machine à glaçons (1) comprend : un récipient de stockage de glaçons (10), un dispositif d'alimentation en glace (20) situé au niveau d'une partie inférieure du récipient de stockage de glaçons (10) et pouvant tourner, et un dispositif de détection (30) pour détecter un état de plein-glace du récipient de stockage de glace (10). Le procédé de commande comprend : chaque fois après un achèvement séquentiel d'une opération de fabrication de glace et d'une opération de dégivrage, la réalisation d'une détection de plein-glace pour détecter si le récipient de stockage de glace (10) est dans l'état de plein-glace; l'exécution de l'opération de fabrication de glace et de l'opération de dégivrage lorsqu'il est déterminé au moyen d'une détection de plein-glace que le récipient de stockage de glaçons (10) n'est pas dans l'état de plein-glace; l'entraînement du dispositif d'alimentation en glace (20) de façon à effectuer une correction de plein-glace lorsqu'il est déterminé au moyen de la détection de plein-glace que le récipient de stockage de glaçons (10) se trouve dans l'état de plein-glace, et l'enregistrement du nombre de corrections de plein-glace après achèvement de la correction de plein-glace; et l'exécution, après chaque correction de plein-glace, une détection de correction pour détecter si le récipient de stockage de glaçons (10) est toujours dans l'état de plein-glace. L'invention corrige un résultat de détection d'état de plein-glace, ce qui permet d'éviter un problème dans lequel le récipient de stockage de glace est déterminé de manière erronée comme étant dans l'état de plein-glace avant que le récipient de stockage de glace ait été complètement rempli du fait de la glace ne s'accumulant pas horizontalement.
