Definitions

  • the invention relates to a dust collector for a
  • Electric hand machine tool in particular electric hand grinder, according to the preamble of claim 1.
  • the dust collector according to the invention with the features of claim 1 has the advantage that a compact design of the dust collector with a short overall length and large by integrating the inlet nozzle in the dust collector itself and the spatial arrangement of the inlet nozzle, dust collection chamber, filter and exhaust air opening in the working position of the electric handheld power tool Dust collection rate is reached.
  • the concealed inlet nozzle allows an aesthetically attractive dust collector to be created, the outer contours of which adapt to the machine housing in a design-optimized manner.
  • the mouth opening of the inlet connection is close to the rear boundary wall of the dust collection chamber facing away from the connection opening of the inlet connection and is arranged there so that the axis of the mouth opening is directed towards the boundary wall.
  • the dust advantageously enters the rear boundary wall of the dust collection chamber and is evenly distributed over the dust collection chamber by the air flow.
  • the uniformity of the dust distribution is further improved in that, according to a preferred embodiment of the invention, the exhaust air opening and the upstream dust filter extend over the entire dust collecting chamber above it.
  • Dust collection chamber from an open top box-like housing and one including the cover which closes the housing and is removable from the housing.
  • the inlet connector is integrated in the housing base and the exhaust air opening is arranged in the cover.
  • the dust filter is preferably attached to the underside of the cover by ultrasonic welding, the dust filter preferably being designed as a pleated filter.
  • the inlet connection is conical and tapers from the connection opening to the outlet opening, which has a positive effect on the air speed in the inlet connection and the associated dust transport.
  • locking hooks are provided on the housing for locking in corresponding locking recesses in the machine housing.
  • These latching hooks are preferably injection-molded in one piece onto the side walls of the housing and protrude beyond its end facing the machine housing. This constructive measure allows the dust collector to be removed quickly and easily from the machine housing and put back on by simply locking it in place.
  • Elastic sealing rings between the inlet socket of the dust collector and the dust ejection socket of the machine housing ensure reliable dust sealing of the dust collector.
  • the cover has an elastic edge that can be placed on the housing and has an air sealing function.
  • the cover carrying the dust filter thus closes the housing in a dust-tight manner and can be easily removed from the housing and replaced to empty the dust-collecting chamber.
  • FIG. 2 shows a longitudinal section of the dust collecting container according to section line II - II in FIG. 5,
  • Fig. 3 is a top perspective view of a lid of the
  • FIG. 4 shows a perspective top view of a housing of the dust collecting container according to FIGS. 1 and 2 which can be closed by the cover according to FIG. 3,
  • FIG. 5 is a view of the housing in the direction of arrow V in FIG .. 4
  • the eccentric sander shown in side view in FIG. 1 as an exemplary embodiment of an electric hand-held grinder has a machine housing 11, on the underside of which a sanding plate 12 is arranged, which can be covered with an abrasive sheet and is driven in rotation.
  • the grinding dust produced during grinding is sucked through the grinding plate 12 by means of a fan wheel which is arranged on the drive shaft of the grinding plate 12 and cannot be seen here, and is blown out via a dust ejection nozzle 13 which is integrally formed on the machine housing 11.
  • Dust ejection clip 13 a dust collector 14 is pushed dust-tight.
  • the dust collecting container 14 which is detachably attached to the machine housing 11 and can be seen in side view and partially in section in FIG. 1, in longitudinal section in FIG. 2 and in its individual parts in FIGS. 3-5, comprises a box-like housing 15 which is open at the top (Fig. 4) and one on the housing 15 attachable cover 16 (Fig. 3), which closes the housing 15 dust and airtight and together with the housing 15 includes a dust collection chamber 17.
  • a cover 16 there is an exhaust air opening 18 which is covered by a web grille 19.
  • the cover 16 is placed on the housing 15, the exhaust air opening and the web grille 19 extend almost over the entire open top of the housing 15 Housing 15 is pressed (Fig. 1).
  • a dust filter 20 is fastened on the underside of the cover 16 facing the dust collection chamber 17.
  • the dust filter 20 is preferably designed as a pleated filter and fixed to the cover 16 by means of ultrasonic welding.
  • an inlet connection 21 is integrated, which has a connection opening 22 for attachment to the dust ejection connection 13 of the machine housing 11 and an orifice opening
  • the inlet connector 21 is conical and tapers its cross-section from the connection opening 22 to the mouth opening 23.
  • the connection opening 22 is set back from the end wall 151 that can be attached to the machine housing 11, and the opening opening 23 is close to the rear housing wall 152 facing away from the connection opening 22 of the housing 15, the axis of the orifice opening 23 being directed towards the rear housing wall 152.
  • the housing 15 is made of plastic by injection molding, the inlet connection 21 running on the housing base 153 being molded on at the same time. In one piece with molded on the housing 15 are two locking hooks
  • the air flow sucked in by the rotating fan wheel in the machine housing 11 through the grinding divider 12 and blown out via the dust ejection connection 13 is conveyed into the inlet connection 21 and enters the dust collection chamber 17 near the rear housing wall 152 of the housing 15.
  • the air stream flows through the dust collecting chamber 17 and leaves the dust collecting container 14 through the dust filter 20 via the exhaust air opening 18.
  • the dust is retained on the dust filter 20 and the dust is deposited in the dust collecting chamber 17.
  • the large-area design of the exhaust air opening 18 and the arrangement of the orifice opening 23 of the inlet connector 21 ensure that the dust is deposited in the dust collecting chamber 17 to a large extent.
  • the dust collector 14 is very compact and does not hinder or otherwise impair the handling of the electric hand grinder.
  • the locking hooks 24 and by designing the front end wall 151 of the housing 15 such that it rests positively on the machine housing 11 when the locking hooks 24 are locked, a reliable and secure hold of the dust collecting container 14 on Machine housing 11 guaranteed. If the shape of the housing 15 with the cover 16 is adapted to the outer contours of the machine housing 11, a design-optimized unit consisting of an electric hand grinder and a dust collector 14 is obtained.
  • the dust collector 14 described is not only suitable for use in the described electric hand grinder. Rather, it can be used in any electric hand machine tool for machining workpieces, with which material is thus removed from the workpiece by machining a workpiece. More examples of such
  • Electric hand machine tools are e.g. electric hand planer or electric hand saw machines.
