Abstract

La présente invention concerne un dispositif d'admission/échappement d'une hotte de cuisine, permettant d'obtenir une amélioration de l'efficacité d'échappement au moyen de la réduction à un minimum de l'écoulement dans la direction opposée à la direction d'aspiration, se produisant au niveau du bord d'un cylindre d'admission.　La présente invention est caractérisée en ce qu'elle comprend : un cylindre d'admission (4) en communication avec l'espace autour d'une hotte de cuisine ; un cylindre d'échappement (5) destiné à former un passage d'air étanche annulaire (A) autour du cylindre d'admission et entourant le cylindre d'admission ; et une soufflante (6) destinée à alimenter en air comprimé le passage d'air. L'extrémité aval du cylindre d'admission est séparée du cylindre d'échappement sur toute la circonférence, formant ainsi une sortie de jet annulaire (B) dans le passage d'air, la sortie de jet annulaire étant en communication avec l'intérieur du cylindre d'échappement. L'extrémité aval du cylindre d'admission est formée de façon à se rapprocher progressivement de la paroi interne du cylindre d'échappement sur toute la circonférence, formant ainsi une partie d'étranglement annulaire (C) comportant la sortie de jet en tant que partie d'évacuation ; et une plaque de guidage du vent (7), destinée à guider l'air comprimé apporté au passage d'air vers la sortie de jet, est disposée dans la partie d'étranglement.
