Abstract
Eine Handwerkzeugmaschine (10) mit einem Gehäuse (12) und einem Ausblasstutzen (20), an dem lösbar mit ihrem Einblasstutzen (22) eine Staubbox (21) befestigbar ist, wird dadurch leistungsfähiger, dass die Staubbox (21) auswechselbar mit einem rohrartigen, insbesondere rotationssymmetrischen, Filter, insbesondere Faltenfilter, bestückbar ist und eine daran angepasste Außenkontur hat.A handheld power tool (10) with a housing (12) and a blow-out nozzle (20), to which a dust box (21) can be detachably fastened with its blow-in nozzle (22), becomes more efficient in that the dust box (21) can be replaced with a tubular, in particular rotationally symmetrical filters, in particular pleated filters, can be fitted and has an outer contour adapted to them.
Description
Stand der TechnikState of the art
Die Erfindung geht aus von einer Handwerkzeugmaschine nach der Gattung des Anspruchs 1.The invention is based on one Hand machine tool according to the preamble of claim 1.
Aus der WO 00/73016 ist eine Handwerkzeugmaschine mit einer Staubbox bekannt, die in einem luftdurchlässigen, austauschbaren Deckel ein Faltenfilter trägt, das wirkungsvoll Staub, insbesondere Feinstaub, zurückhält und erheblich zur Verbesserung der Arbeitshygiene und Sicherheit beiträgt. Diese kastenförmige Staubbox ist verhältnismäßig aufwändig herzustellen. Außerdem sind hinsichtlich ihrer Filter- und Staubabsaugleistung Grenzen erreicht.WO 00/73016 is a hand tool known with a dust box, which is in an air-permeable, interchangeable lid carries a pleated filter that effectively dust, particulate matter in particular, retains and significantly contributes to the improvement of occupational hygiene and safety. This boxy Dust box is relatively complex to manufacture. Moreover are limits with regard to their filter and dust extraction performance reached.
Vorteile der ErfindungAdvantages of invention
Die erfindungsgemäße Handwerkzeugmaschine mit Staubabsaugung mit den Merkmalen des Anspruchs 1 hat demgegenüber den Vorteil, dass eine noch leichtere und formstabilere Staubbox geschaffen worden ist, die eine bisher unerreichte Filterflächengröße, Luftdurchlässigkeit und Filterleistung besitzt. Außerdem ist das zugehörige Filter in Gestalt eines zylindrischen Filterrohrs kostengünstig herstellbar, bequem und umweltfreundlich entleerbar und leicht auswechselbar.The hand tool according to the invention with Dust extraction with the features of claim 1 has the other hand The advantage of creating an even lighter and more stable dust box has been an unprecedented filter area size, air permeability and has filter performance. Moreover is the corresponding one Filters in the form of a cylindrical filter tube can be produced inexpensively, easy and environmentally friendly to empty and easy to replace.
Dadurch, dass die Staubbox als Kegelstumpf oder Zylinder ausgestaltet ist, wobei ein abnehmbarer Deckel ihre hintere Deckfläche bildet, ist sie einfach herstellbar. einfach zu öffnen bzw. leicht und sicher verschließbar und dadurch bequem zu handhaben.Because the dust box as a truncated cone or Cylinder is designed with a removable cover on its rear cover surface forms, it is easy to manufacture. easy to open or light and safe lockable and therefore easy to use.
Dadurch, dass die Staubbox einen zentrischen Staubsammelraum hat und der Deckel diesen luftdicht abschließt, kann die äußere Ringwand bzw. der Zylindermantel der Staubbox als luftdurchlässige Fläche dienen und nah benachbart mit einem zylindrischen bzw. kegeligen Filterrohr bzw. -patrone bestückt werden.Because the dust box one centric dust collecting space and the lid this airtight closes, can the outer ring wall or the cylinder jacket of the dust box serve as an air-permeable surface and closely adjacent with a cylindrical or conical filter tube or cartridge fitted become.
Dadurch, dass die Staubbox einen zentrischen Staubsammelraum hat und der Deckel eine bzw. mehrere Luftaustrittsöffnungen hat und innen einen Staubfilter trägt, ist die Filterleistung der Staubbox verbessert.Because the dust box one centric dust collection and the lid one or more Air outlet openings and has a dust filter inside, is the filter performance the dust box improved.
Dadurch, dass die Staubbox einen exzentrischen Staubsammelraum mit äußerer und innerer Ringwand und der Deckel eine, insbesondere zentrische, Luftaustrittsöffnung hat, können die Luftlöcher statt an die äußere an die innere Ringwand des Ringraums gesetzt werden, so dass die äußere Ringwand eine höhere Formsteifigkeit hat.Because the dust box one eccentric dust collector with outer and inner ring wall and the cover has an air outlet opening, in particular a central one, can the air holes instead to the outside the inner ring wall of the annulus can be set so that the outer ring wall a higher one Has stiffness.
Dadurch, dass sowohl die äußere als auch die innere den exzentrischen Staubsammelraum bildende Ringwand der Staubbox Luftlöcher aufweisen und jeweils dicht von einem rohrartigen Faltenfilter umgeben sind, ist die an sich schon hohe Filterleistung einer Staubbox mit nur einer einzigen gelochten Ringwand nahezu verdoppelt.The fact that both the outer and also the inner ring wall forming the eccentric dust collecting space the dust box air holes have and each tightly surrounded by a tubular pleated filter are the high filter performance of a dust box almost a single perforated ring wall almost doubled.
Dadurch, dass die Staubbox als Stufenzylinder ausgestaltet ist, dessen Bereich mit dem kleineren Zylinderdurchmesser den Eintrittsstutzen für Absaugstaub bildet, ist sie bequem mit der Handwerkzeugmaschine koppelbar.Because the dust box as a stepped cylinder is designed, the area with the smaller cylinder diameter the inlet nozzle for Forms dust, it is convenient with the hand tool coupled.
Dadurch, dass zentral in der radial inneren Ringwand ein Strömungskegel angeordnet ist, dessen Spitze der einströmenden Luft entgegen gerichtet ist und diese radial nach außen, insbesondere in den Ringraum, leitet, sind die Strömungsverluste beim Staubabsaugen im Inneren der Staubbox gering.By being central in the radial inner ring wall a flow cone is arranged, the tip of which is directed against the inflowing air and this is radially outwards, especially in the annulus, the flow losses are at Dust extraction inside the dust box is low.
Dadurch, dass das Filter aus rohrartig gewickeltem Falten-Filterpapier besteht, ist eine besonders große Filterfläche auf einfache Weise realisierbar.Because the filter is made of tubular wrapped pleated filter paper, there is a particularly large filter area easy to implement.
Dadurch, dass die Filter aus zwei konzentrischen Faltenfilterrohren besteht, zwischen denen ein von staubhaltiger Abluft durchströmbarer Ringraum gebildet wird und die mit einem versteifendem Kunststoffkorsett zueinander lagegesichert sind, ist ein besonders effektives Filter geschaffen.By making the filter from two concentric pleated filter tubes, between which one of exhaust air containing dust can be flowed through Annulus is formed and that with a stiffening plastic corset secured to one another is a particularly effective filter created.
Dadurch, dass der Abluftstrom ohne Leckmöglichkeit durch das, insbesondere gegenüber dem Deckel und dem Einströmbereich abgedichtete, Filter, geleitet wird, ist der Staubgehalt der gefilterten Luft minimiert.The fact that the exhaust air flow without leak possibility through that, especially opposite the lid and the inflow area sealed, filter, directed, is the dust content of the filtered air minimized.
Durch das Kunststoffkorsett ist das Filter so stabil, dass daraus der Staub ohne Beschädigungsrisiko bequem ausklopfbar ist.Because of the plastic corset Filters so stable that they can be used for dust without risk of damage is easy to knock out.
Nachstehend ist die Erfindung an Hand einer zugehörigen Zeichnung näher erläutert.The following is the invention Hand of an associated Drawing closer explained.

Da die Lebensdauer einer solchen Filteranordnung in den Staubboxen gemäß den vorstehenden Ausführungsbeispielen die Lebensdauer der zugehörigen Handwerkzeugmaschine um ein Mehrfaches übertrifft, kann für die dargestellten Beispiele auf einen Filterwechsel verzichtet werden.Because the lifespan of such Filter arrangement in the dust boxes according to the above embodiments the lifespan of the associated Handheld machine tool can outperform multiple times for the illustrated Examples of filter changes can be dispensed with.
Für besondere Fälle können für die Stauboxen Faltenfilterpatronen vorgesehen werden, die auswechselbar in eine entsprechende zugehörige Staubbox einsetzbar sind.For special cases can for the Storage boxes are provided that can be replaced in a corresponding dust box can be used.
