Abstract

La présente invention concerne une volute (1) destinée à une hotte de cuisine (100) et la hotte de cuisine (100) pourvue de ladite volute (1). La volute (1) destinée à une hotte de cuisine (100) comprend un corps (10) de volute et une première plaque de recouvrement (103) de commutation. Le corps (10) de volute comprend une plaque inférieure (101), une plaque supérieure, et une plaque de renfermement (102) latérale disposée entre la plaque inférieure (101) et la plaque supérieure. Le corps (10) de volute est pourvu d'une première sortie d'air (104) et d'une seconde sortie d'air (105). La première sortie d'air (104) est formée dans la plaque de renfermement (102) latérale. La première plaque de recouvrement (103) de commutation peut se déplacer entre une position d'ouverture dans laquelle la première sortie d'air (104) est ouverte et une position de fermeture dans laquelle la première sortie d'air (104) est fermée.
