Title (EN) LIQUID BATH VACUUM CLEANER
(FR) ASPIRATEUR A BAIN DE LIQUIDE
Abstract:
(EN) In a top mounted vacuum cleaner liquid (7) is caused to swirl in a debris containment assembly (3) by air drawn in through an angulated tube (6), the liquid (7) acting as a primary filter to entrap debris. A secondary filter (11), moistened by a mist generated by the passage of air through the cleaner, entraps any debris not captured by the primary filter liquid (7). The angulated tube (6) allows the cleaner to operate even when the liquid level is above the lower end of the tube (6).
(FR) Dans un aspirateur dont le moteur est monté dans la partie supérieure, de l'air aspiré au moyen d'un tube angulaire (6) fait tourbillonner du liquide (7) dans un ensemble (3) contenant des détritus, le liquide (7) faisant office de filtre primaire afin d'emprisonner les détritus. Un second filtre (11) humidifié par de la condensation produite par le passage d'air dans l'aspirateur, emprisonne tous les détritus ayant échappé au liquide (7) de filtration primaire. Le tube angulaire (6) permet le fonctionnement de l'aspirateur même lorsque le niveau du liquide se situe au-dessus de l'extrémité inférieure du tube (6).
