Title
(EN) DEVICE FOR STERILISING OBJECTS BY APPLYING UV-C LIGHT IRRADIATION
(ES) APARATO ESTERILIZADOR DE OBJETOS MEDIANTE APLICACIÓN DE IRRADIACIÓN DE LUZ UV-C
(FR) APPAREIL STÉRILISATEUR D'OBJETS PAR APPLICATION DE LUMIÈRE UV-C
Abstract
(EN) Disclosed is a sterilising device (1) for sterilising objects by applying UV-C light irradiation and a flow of ozone, capable of optimising sterilisation by reducing the time of exposure of several objects at the same time, and ensuring that the entire surface receives the minimum dose necessary for sterilisation, with purification of the residual air on completion of each cycle; the device comprises a multiple sterilising radiation source (20) having at least one first UV-C light-emitting tube (21) and at least one second UV-C light-emitting tube (22), parallel to each other; the multiple radiation source (20) is installed on a mobile component (30) that is displaced linearly relative to a static component (40) comprising at least one support (41) for the positioning of the objects to be treated, this being transparent to UV-C irradiation and permeable to ozone flows, comprising a first irradiable side (42) facing a second irradiable side (43); where the mobile component (30) simultaneously displaces the UV-C light-emitting tubes, maintaining said first tube (21) at a first distance (d1) relative to the aforementioned first irradiable side (42) of the support (41), and said second tube (22) at a second distance (d2) relative to the aforementioned second irradiable side (43) of the same support (41).

(FR) La présente invention concerne un appareil stérilisateur (1) d'objets par application de lumière UV-C et d'un flux d'ozone, capable d'optimiser la stérilisation par la réduction du temps d'exposition de divers objets en même temps et d'assurer que toute la surface reçoive une dose minimale nécessaire de stérilisation, avec la purification de l'air résiduel à la fin de chaque cycle. L'appareil comprend une source multiple (20) d'irradiation de stérilisation qui comporte au moins un premier tube (21) et au moins un second tube (22) qui émettent de la lumière UV-C et sont parallèles entre eux; la source multiple (20) d'irradiation est montée sur un constituant mobile (30) qui se déplace de manière linéaire par rapport à un constituant statique (40) qui comprend au moins un support (41) pour positionner les objets à traiter, transparent à l'irradiation UV-C et perméable aux flux d'ozone, et comprenant une première face irradiable (42) opposée à une seconde face irradiable (43); lequel constituant mobile (30) déplace, simultanément, les deux tubes émetteurs de lumière UV-C, maintenant ledit premier tube (21), à une première distance (d1), par rapport à ladite première face irradiable (42), du support (41) et ledit second tube (22) à une seconde distance (d2) par rapport à ladite seconde face irradiable (43) dudit support (41).
