Abstract

La présente invention porte sur un dispositif de pressurisation d'évacuation de hotte locale. Des ventilateurs d'aspiration horizontaux sont disposés à une extrémité d'une hotte d'évacuation, suivant la longueur de chaque côté de la hotte dans les directions verticale et longitudinale. De l'air stagnant pollué autour de l'extrémité de la hotte qui n'a pas été évacué est évacué, et ne se propage pas à l'intérieur du fait de la couche d'air, qui est un jet d'air. L'air dans l'angle de propagation du courant d'air d'un jet d'air déchargé à partir de chaque surface latérale d'un système de source de chaleur inférieur par le ventilateur d'aspiration, est poussé, au niveau d'un angle de surface inclinée, à l'intérieur de la hotte par l'air de décharge aspiré. Tous les ventilateurs sont actionnés conjointement en même temps, de telle sorte que l'air est déchargé rapidement par un collier de guidage pour une attraction de courant d'air dans la hotte et, par conséquent, l'air pollué est poussé et aspiré.
