Die Erfindung bezieht sich auf eine Staubschutzeinrichtung für die vom Motorgebläserad eines Elektrohandgeräts, insbesondere Handschleifgeräts, von einem Filterkasten über einen biegsamen Schlauch angesaugte Kühlluft.The invention relates to a dust protection device for the motor fan wheel Electric hand-held device, in particular hand-held grinding device, from a filter box to a flexible one Hose sucked in cooling air.
Bei Einrichtungen dieser Art wurde auch schon der in Staubluft Arbeitende mit Helmen und Filtermasken od. dgl. geschützt.In institutions of this type, those working in dusty air with helmets and filter masks were also used or the like. Protected.
Ausgangspunkt für die Erfindung ist eine Staubschutzeinrichtung für die vom Motorgebläserad eines Elektrohandgeräts, insbesondere Handschleifgeräts, von einem Filterkasten über einen biegsamen Schlauch angesaugte Kühlluft mit Verwendung eines gefilterte Luft erhaltenden Sichtschutzhelmes für den Bedienenden.The starting point for the invention is a dust protection device for the motor fan wheel Electric hand-held device, in particular hand-held grinding device, from a filter box to a flexible one Hose sucked in cooling air with the use of a filtered air preserving protective helmet for the Operator.
Der Erfindung liegt nun die besondere Aufgabe zugrunde, eine solche Staubschutzeinrichtung mit Filterkasten und unter Verwendung eines Sichtschutzhelmes für den Bedienenden so auszubilden, daß unbeschadet der Sicherheit für den Bedienenden mit einem Minimum von Aufwand ein Gerät, das sich leicht handhaben läßt und nicht sperrig ist, geschaffen wird.The invention is based on the particular object of having such a dust protection device To design the filter box and using a protective helmet for the operator in such a way that that without prejudice to the safety for the operator with a minimum of effort a device that can be handled easily and is not bulky, is created.
Erfindungsgemäß wird die gefilterte Motorkühlluft zuerst durch den Sichtschutzhelm von einem einzigen Filterkasten aus geführt, so daß es eines besonderen Filters für den Sichtschutzhelm nicht bedarf.According to the invention, the filtered engine cooling air is first passed through the protective helmet from a single one Filter box out so that there is no need for a special filter for the protective helmet.
In Weiterbildung des Erfindungsgedankens wird in die Saugleitung der Staubschutzeinrichtung zur Regelung der Temperatur der Frischluft eine Heizspirale eingeschaltet, deren Schalter in Greifnähe des Bedienenden liegt.In a further development of the inventive concept, the dust protection device is used for control purposes in the suction line the temperature of the fresh air, a heating coil is switched on, its switch within easy reach of the operator lies.
Auf diese Weise wird erreicht, daß der Arbeitende durch die direkte Einatmung der frischen Kühlluft seinerseits nicht geschädigt wird.In this way it is achieved that the worker by the direct inhalation of the fresh cooling air itself is not harmed.
An Hand der Zeichnung ist die Erfindung näher erläutert:The invention is explained in more detail using the drawing:
Das großflächige Filter ist über den Schlauch 2 mit dem Staubschutz- und Sichthelm 3 verbunden.The large-area filter is connected to the dust protection and sight helmet 3 via the hose 2.
Durch den Schlauch 4 wird die angesaugte, staubfreie Kühlluft vom Helm 3 zum Lüfter des Motorhandschleifers 5 weitergeführt.The suctioned, dust-free cooling air is passed through the hose 4 from the helmet 3 to the fan of the motorized hand grinder 5 continued.
In Greifnähe des Arbeitenden ist weiter ein Schalter 6 für eine besondere vom Motor abzweigende doppelpolige Speiseleitung 7 für die Heizspirale 8 eingebaut. Auf diese Weise ist der Arbeitende in die Lage versetzt, die Kühlluft nach Bedarf zu temperieren. A switch 6 for a special branching off from the engine is also within easy reach of the worker double-pole feed line 7 for the heating coil 8 installed. This way the worker is in enables the cooling air to be tempered as required.

Ferner kann im Helm 3 eine gleichfalls dem Zugriff des Bedienenden leicht zugängliche Luftklappe 9 angebracht werden, so daß der Bedienende in der Lage ist, sich Frischluft zu verschaffen, sobald der Motor zu arbeiten aufhört.Furthermore, an air flap 9, which is also easily accessible to the operator, can be located in the helmet 3 be attached so that the operator is able to get fresh air as soon as the Engine stops working.
