Abstract

Die Erfindung betrifft einen Heizlüfter (2) mit einem Kunststoffgehäuse (4), einer mit zu erwärmender Luft unmittelbar beaufschlagten elektrischen Heizeinrichtung (6) und einer elektromotorischen Lüftereinrichtung (8). Er zeichnet sich dadurch aus dass die Heizeinrichtung (6) zumindest nach oben und unten hin von einer metallischen Abschirmung (16) umgeben ist, so dass im Bereich der Heizeinrichtung (2) entflammter Staub keine Kunststoffkomponenten erfassen kann und nach unten fallender entflammter Staub nicht auf Kunststoffkomponenten des Kunststoffgehäuses (4) gelangen kann, und dadurch dass die metallische Abschirmung (16) in einer Umfangsrichtung durchgehend von einem metallischen Rohrabschnitt (18) gebildet ist und dadurch dass die metallische Abschirmung (16) in einer axialen Strömungsrichtung (30) derart erstreckt ist, dass sie auch die Lüftereinrichtung (18) und deren Flügelrad (10) vorzugsweise vollumfänglich umgibt, und dadurch dass die metallische Abschirmung (16) sich im wesentlichen von einer Einlassöffnung (12) bis zu einer Ausblasöffnung (14) des Heizlüfters (2), im Wesentlichen über die gesamte Tiefe des Heizlüfters (2), erstreckt und dadurch dass die Heizeinrichtung (6) und die Lüftereinrichtung an der Abschirmung (16) montiert und gehalten ist, und die Abschirmung (16) am Kunststoffgehäuse (4) montiert und gehalten ist.

The invention relates to a heating fan (2) having a plastic housing (4), an electrical heating device (6) which is directly exposed to air to be heated and an electromotive fan device (8). It is characterized in that the heating device (6) is surrounded by a metallic shield (16) at least upwards and downwards, so that flammable dust in the region of the heating device (2) can not detect any plastic components and flammable dust falling downwards does not Plastic components of the plastic housing (4) can pass, and in that the metallic shield (16) is formed in a circumferential direction throughout of a metallic pipe section (18) and in that the metallic shield (16) in such an axial flow direction (30) extends in that it preferably also completely surrounds the fan device (18) and its impeller (10), and in that the metallic shield (16) extends essentially from an inlet opening (12) to an outlet opening (14) of the heater fan (2), substantially over the entire depth of the fan heater (2), and in that the heater (6) and the fan assembly is mounted and retained on the shield (16) and the shield (16) is mounted and retained on the plastic housing (4).
