(EN) REFRIGERATED DISPLAY CASE AND CONTROL METHOD THEREOF
(FR) VITRINE RÉFRIGÉRÉE ET SON PROCÉDÉ DE COMMANDE
Abstract
(EN) A refrigerating display cabinet and a control method therefor. The refrigerating display cabinet comprises: a cabinet body having an inner receiving space; a cabinet door controlled to open or close the inner receiving space; a timing portion configured to calculate a holding duration of the current state of the cabinet door of the refrigerating display cabinet; and a control portion configured to obtain a preset period of time, and control the cabinet door to open or close based on a result of comparison between the holding duration of the current state of the cabinet door and the preset period of time.
(FR) L'invention concerne une vitrine à réfrigération et son procédé de commande. La vitrine à réfrigération comprend : un corps d'armoire ayant un espace de réception interne ; une porte d'armoire commandée de façon à ouvrir ou à fermer l'espace de réception interne ; une partie de temporisation configurée de façon à calculer une durée de maintien de l'état actuel de la porte d'armoire de la vitrine à réfrigération ; et une partie de commande configurée de façon à obtenir une période de temps pré-établie, et à commander la porte d'armoire de façon à s'ouvrir ou à se fermer sur la base d'un résultat de comparaison entre la durée de maintien de l'état actuel de la porte d'armoire et la période de temps pré-établie.
