Abstract

L'invention concerne une unité de ventilation combinée à écoulement radial et transversal. Sur un ventilateur classique à écoulement transversal 19, 20 est monté un ventilateur radial, du côté opposé au moteur, à l'aide de cames 2 formant montage à baïonnette. Le boîtier 1 du ventilateur radial est formé en une pièce moulée sous pression. Dans ce boîtier, on dispose un arbre 3 exempt de vibration grâce à deux paliers séparés, la roue 4 du venti ateur radial étant fixée d'un côté de l'arbre et la turbine 19 à écoulement transversal étant fixée de l'autre côté. L'invention s'applique en particulier aux cuisinières électriques.
