Description

Motorkühlung an Staubsaugern Gegenstand der Erfindung ist eine Motorkühlung an Staubsaugern mit als Führungsstange dienendem Luftzuleitungsrohr. Das Neue der Erfindung beruht darin, daß der an der unteren Seite eines etwa-parallel zu dem Luftzuleitungsrohr angebrachten Staubfangbehälters befestigte Motor mit Flügelrädern den durch den Staubfangbehälter gesaugten gereinigten Luftstrom durch einen Auslaßkrümmer mittels eines an der Auslaßöffnung befestigten Leitbleches gegen das Motorgehäuse bläst.Motor cooling on vacuum cleaners The invention relates to motor cooling on vacuum cleaners with an air supply pipe serving as a guide rod. The new of the Invention is based on the fact that the on the lower side of an approximately-parallel to the Air supply pipe attached dust collector attached motor with impellers the cleaned air flow sucked through the dust collector through an exhaust manifold against the motor housing by means of a guide plate attached to the outlet opening blows.

Durch diese Anordnung wird der Motor des Staubsaugers auf einfachste Weise wirksam gekühlt.This arrangement makes the vacuum cleaner motor extremely simple Way effectively cooled.

In der Zeichnung bezeichnet a, a' das als Führungsstange dienende Luftzuleitungsrohr, das mit einer Ansaugedüse b ausgerüstet ist. c ist ein Rohrzwischenstück, das in bekannter Weise zur Aufnahme eines mit Schauglas d versehenen Umschaltventils e eingerichtet ist. Ein Knierohr f des Rohrzwischenstückes c bildet den Anschluß für einen Staubfangbehälter g, in dem sich ein Filtersack o. dgl. befindet. Der Motor lt ist an der unteren Seite dieses Behälters befestigt, wobei die Flügelräder i, j dieses Motors in einem Gehäuse k untergebracht sind, das nach einer Seite hin offen und zu einem Auslaßkrümmer in ausgebildet ist. Bei ia ist an dem Krümmer ein Leitblech o angebracht, das die abgeblasene,. filtrierte Luft gegen das Motorgehäuse h drückt. Rollen p, q dienen zur Abstützung des Saugers, von denen die Rollen p an der Ansaugedüse b, die Rollen q am Auslaßkrümmer m befestigt sind.In the drawing, a, a ' denotes the air supply pipe serving as a guide rod, which is equipped with a suction nozzle b. c is an intermediate pipe piece which is set up in a known manner to accommodate a switching valve e provided with a sight glass d. An elbow tube f of the intermediate tube piece c forms the connection for a dust container g, in which a filter bag or the like is located. The motor lt is fastened to the lower side of this container, the impellers i, j of this motor being accommodated in a housing k which is open on one side and is formed to an exhaust manifold in. At ia a baffle o is attached to the manifold, which the blown off. filtered air presses against the motor housing h. Rollers p, q are used to support the nipple, of which the rollers p are attached to the suction nozzle b and the rollers q are attached to the exhaust manifold m.
