Abstract

La présente invention concerne une structure d'aspiration d'appoint, et un procédé correspondant de décharge de la source de pollution d'un plan de travail. La structure d'aspiration comporte une hotte aspirante et un appareil de soufflage d'air. La hotte aspirante, disposée en regard du plan de travail, se présente avec un orifice d'aspiration pour la source de pollution, et une joue partant du pourtour de l'orifice d'aspiration de façon à guider la source de pollution. L'appareil à soufflage d'air produit un courant à flux d'air en direction de l'orifice d'aspiration et passant le long de la joue de façon à guider la source de pollution. La structure d'aspiration d'appoint peut augmenter l'effet collecteur de l'écoulement de la pollution vers la hotte d'aspiration, et il est facile de recueillir la source de pollution. La source de pollution retombe dans une région enfermée et ne se diffuse pas vers l'extérieur. La structure d'aspiration peut recueillir la source de pollution avec une efficacité élevée et occuper un petit espace.
