GEBIET DER ERFINDUNGFIELD OF THE INVENTION
Die vorliegende Erfindung betrifft eine Staubabsaugeinrichtung für eine Handwerkzeugmaschine, wie zum Beispiel aus der
OFFENBARUNG DER ERFINDUNGDISCLOSURE OF THE INVENTION
Die erfindungsgemässe Staubabsaugeinrichtung für eine Handwerkzeugmaschine mit einem Lüfterrad, einem Absaugkopf, einem Absaugkanal, der einen Luftstrom zwischen einer saugenden Seite des Lüfterrads und dem Absaugkopf führt. Ein Zuluftkanal führt einen Luftstrom zwischen einer blasenden Seite des Lüfterrads und dem Absaugkopf. Die von dem Lüfterrad angesaugt Luft wird nur teilweise aus der Staubabsaugeinrichtung ausgeblasen und ein Anteil der angesaugten Luft wird dem Absaugkopf zugeführt. Der Energiebedarf zum Bewegen der Luft kann hierdurch verringert werden.The dust extraction device according to the invention for a hand tool with a fan wheel, a suction head, a suction channel, which guides an air flow between a sucking side of the fan wheel and the suction head. A supply air duct leads an air flow between a blowing side of the fan and the suction head. The sucked by the fan air is only partially blown out of the dust extraction and a portion of the intake air is fed to the suction. The energy required to move the air can thereby be reduced.
Eine Ausgestaltung sieht vor, dass der Absaugkopf eine Absaugöffnung zum Anbinden an den Absaugkopf und eine von der Absaugöffnung getrennte Zuluftöffnung zum Anbinden an den Zuluftkanal aufweist. Die Zuluftöffnung kann der Absaugöffnung diametral gegenüberliegend angeordnet sein.An embodiment provides that the suction head has a suction opening for attachment to the suction head and a supply air opening separate from the suction opening for connection to the supply air duct. The supply air opening may be arranged diametrically opposite the suction opening.
Eine Ausgestaltung sieht vor, dass der Absaugkopf eine Öffnung zum Durchführen eines Werkzeugs aufweist.An embodiment provides that the suction head has an opening for performing a tool.
Eine Ausgestaltung sieht vor, dass ein Filter zwischen dem Absaugkanal und der saugenden Seite des Lüfterrads angeordnet ist.An embodiment provides that a filter between the suction and the sucking side of the fan is arranged.
Eine Ausgestaltung sieht vor, dass die Abmessungen des Zuluftkanals und des Absaugkanals derart bemessen sind, dass ein Volumenstrom durch den Zuluftkanal zwischen 10 Prozent und 25 Prozent eines Volumenstroms durch den Absaugkanal beträgt. Ein Abluftkanal kann die blasende Seite des Lüfterrads mit einer Öffnung eines Gehäuses der Staubabsaugeinrichtung verbinden.An embodiment provides that the dimensions of the supply air duct and the suction duct are dimensioned such that a volume flow through the supply air duct is between 10 percent and 25 percent of a volume flow through the suction duct. An exhaust duct may connect the blowing side of the fan to an opening of a housing of the dust extractor.
