Abstract

L'invention concerne un appareil de stérilisation par UV présentant une fonction de circulation d'air comprenant : une unité de pilier présentant une forme cylindrique avec un intérieur creux ; un support pour supporter un côté de l'unité de pilier ; une pluralité de lampes UV disposées le long de la circonférence de l'unité de pilier cylindrique ; un couvercle pouvant être fixé/détaché pour recouvrir l'unité de pilier et la pluralité de lampes UV lorsqu'il est installé ; un capteur de couvercle qui détecte la fixation/détachement du couvercle ; une unité d'aspiration d'air pour permettre à un espace intérieur du couvercle installé d'être en communication avec l'extérieur ; un ventilateur soufflant qui est conçu pour aspirer et évacuer l'air dans l'unité de colonne cylindrique ; et un micro-ordinateur qui met en œuvre un mode de circulation d'air, dans lequel le ventilateur soufflant est actionné tandis que les lampes UV sont allumées, lorsque l'installation de couvercle est détectée, et met en œuvre un mode de stérilisation de périphérie, dans lequel la périphérie est stérilisée par irradiation UV directe en allumant les lampes UV, lorsque le détachement du couvercle est détecté.
