Abstract

La présente invention concerne un ventilateur intégré à un amortisseur, qui est conçu en ce qu'il comprend : un boîtier dans lequel est formée une chambre d'écoulement d'air et qui est pourvu d'un orifice de sortie d'air communiquant avec la chambre d'écoulement d'air; une hélice reliée de manière rotative à un arbre rotatif d'un moteur et disposée dans le boîtier; et un amortisseur de refoulement pour ouvrir et fermer l'orifice de sortie d'air. Selon la présente invention, étant donné que chaque élément dans le ventilateur peut être démonté par une simple opération de fixation/détachement, un utilisateur peut résoudre des problèmes qui se sont produits dans chacun des éléments ou effectuer facilement une maintenance telle qu'un nettoyage, simplement par le démontage direct de chaque élément dans le ventilateur de manière séquentielle.
