Abstract

L'invention concerne un appareil de traitement de vêtements, comprenant un dispositif de génération de plasma (10), une cuve (40), une boîte (30) et un couvercle arrière (20), la cuve (40) étant supportée de manière rotative sur la boîte (30) ; une entrée d'air (40a) étant prévue à l'extrémité arrière de la cuve (40) ; un premier orifice d'air (30a) et un second orifice d'air (30b) étant prévus dans une paroi latérale arrière (31) de la boîte (30) ; le second orifice d'air (30b) étant en communication avec l'entrée d'air (40a) ; le couvercle arrière (20) étant disposé sur un côté arrière de la paroi latérale arrière (31) de la boîte (30), et comportant un canal de guidage d'écoulement (20a) ; et le canal de guidage d'écoulement (20a) amenant le premier orifice d'air (30a) à communiquer avec le second orifice d'air (30b). Du plasma généré par le dispositif de génération de plasma (10) dans l'appareil de traitement de vêtements au moyen d'une ionisation haute tension d'air permet d'obtenir les effets d'une stérilisation et d'une désodorisation, et le plasma généré peut entrer dans la cuve (40) avec un écoulement d'air de séchage dans le canal de guidage d'écoulement (20a) et se diffuser, améliorant ainsi l'efficacité de stérilisation et de désodorisation.
