Abstract

La présente invention concerne une machine à glaçons dans laquelle un échange de chaleur est effectué avec une partie d'échange de chaleur comprenant au moins l'une parmi une partie de refroidissement et une partie de chauffage, la machine à glaçons comprenant : une boîte de commande ; un plateau à glaçons qui s'étend depuis un côté de la boîte de commande ; une partie de drainage qui reçoit de l'eau tombant de la partie d'échange de chaleur ou du couvercle de trajet d'écoulement suivant et qui lui permet de s'écouler vers un côté de celle-ci ; un dispositif de chauffage de drainage disposé dans la partie de drainage ; un ventilateur de circulation qui génère un écoulement d'air sur une surface du plateau à glaçons, qui est situé sur un côté de la boîte de commande, et qui a une direction de décharge disposée horizontalement, verticalement, latéralement ou avec une inclinaison prédéterminée pour décharger de l'air introduit par le couvercle de trajet d'écoulement suivant ; le couvercle de trajet d'écoulement qui a un espace interne formé à l'intérieur de celui-ci pour guider l'écoulement d'air généré par le ventilateur de circulation, et qui renferme la partie de refroidissement et la partie de chauffage qui sont disposées sous le plateau à glaçons ; et une partie de support de pression qui est formée sur le couvercle de trajet d'écoulement et qui supporte au moins une partie de la partie d'échange de chaleur.
