Abstract

Machine de nettoyage à sec dans laquelle un mécanisme de purification pourvu d'un dispositif à filtre contenant une cartouche filtrante (33) et monté entre une cuve de solvant et une cuve de nettoyage, et un mécanisme de séchage servant à faire circuler de l'air chaud propre à travers la cuve de nettoyage sont assemblés et constituent des circuits indépendants l'un de l'autre. L'air chaud provenant du mécanisme de séchage est libéré par des orifices d'entrée de solvant du dispositif à filtre (3) de sorte que ledit dispositif (3) peut former de façon sélective un mécanisme de purification qui contourne la cuve de nettoyage (1) et la cuve de solvant (2).
