Abstract

L'invention se rapporte à une machine de nettoyage à sec équipée de mécanismes de nettoyage utilisant des filtres à cartouches. Dans cette machine, lors de la récupération du solvant toxique qui reste dans les filtres à cartouches (33) incorporés dans la machine de nettoyage à sec, les filtres (33) eux-mêmes, une fois qu'ils commencent à perdre leur pouvoir filtrant après un usage continu pendant une période fixe, peuvent être nettoyés au lieu d'être remplacés, tout en étant maintenus dans les dispositifs de filtrage incorporés dans la machine de nettoyage, et, en faisant soufler de l'air chaud depuis le mécanisme de séchage à travers des conduits centraux (34), on peut adapter sélectivement les dispositifs de filtrage pour qu'ils forment les mécanismes de nettoyage en les faisant passer par la cuve de nettoyage (1) et la cuve à solvant (2).
