Abstract

L'invention concerne une hotte aspirante de cuisinière dont le boîtier comprend une surface supérieure (35), une surface arrière (36) verticale, une plaque de couverture latérale (14) et une surface (15) protubérante ou arquée s'étendant de haut en bas servant à aspirer la fumée. Deux ouvertures d'aspiration, l'une supérieure (13) l'autre inférieure (16) sont ménagées sur la surface d'aspiration (15) et coïncident avec deux extracteurs supérieur (3) et inférieur (6) logés dans le boîtier de la hotte. Le boîtier de la hotte est configuré de manière que le système d'extraction inférieur soit partiellement incorporé dans le mur, que la partie supérieure du boîtier présente un rideau de gaz et que l'intérieur du boîtier renferme un système de nettoyage automatique, un système de purge et un système d'alimentation en eau. La hotte de cette invention permet de réduire la distance séparant les ouvertures d'aspiration de la source de fumée, de renforcer l'efficacité de l'aspiration sans pour autant avoir à ouvrir le boîtier. Par ailleurs, la fumée est nettoyée au sein du boîtier.
