Definitions

  • the invention is based on a hand machine tool the type of claim 1.
  • the performance of the well-known dust box is due to the limited suction unit integrated in the hand tool, that of a fan and associated air duct system exists and in terms of performance and efficiency can hardly be improved.
  • the hand-held machine tool according to the invention with the features of claim 1 has the advantage that the dust extraction performance compared to the known handheld power tools Dust box is significantly increased without changing the hand machine tool integrated dust extraction system and without increased fine dust emissions.
  • the fact that the motor is a low voltage motor is one trouble-free power supply possible via busbars, which is covered by the dust collection box and the dust outlet nozzle and the housing of the hand machine tool are led.
  • the hand-held power tool supplied with mains voltage contains a transformer is a safe one Power supply for the dust extraction unit with low voltage possible.
  • the motor is equipped as a DC motor is, it is powered by rechargeable batteries or batteries easily possible.
  • the dust box itself has an upper, airtight Carries the emptying lid, the dust box can be emptied without the separate dust extraction unit in contact with the dust comes.
  • the motor has a fan at each shaft end for dust extraction is the one that causes the dust extraction Airflow particularly effective.
  • the invention is based on an associated Drawing explained.
  • FIG. 1 shows a hand tool 10, which is an orbital sander is designed. This has a housing 12 with a upper handle 14, which is in the viewing direction extends to the left, with a from its rear end Electrical connection cable 15 emerges. Protrudes from the handle 14 down a manual button 16 one not closer designated switch for commissioning the hand tool 10th
  • An electric motor 18 is located in the front area of the housing 12 arranged. Its output shaft 20 is non-rotatable with a Fan 22 coupled and rotationally driving with its free end connected to a grinding plate 24.
  • the sanding plate 24 carries axially continuous dust extraction openings 26, due to the resulting grinding dust when working with the Hand tool 10 from an unspecified Workpiece surface can be extracted and via a dust outlet nozzle 28 can be blown into a dust box 36.
  • the Dust box 36 carries in the hand machine tool 10 facing Area a dust inlet connector 35. This spans with its inside diameter the outside diameter of the Dust outlet connector 28 and is detachably fastened there.
  • the dust box 36 can be closed airtight with a lid 38 and open it to empty dust. That lid 38 carries an upward-pointing retaining hook 40, the one Engagement opening 29 of the lower, bow-like area of the Handle 14 passes and in this way the storage box 36th additionally secured on the housing 12.
  • the cover 38 engages with its circumferential locking groove 41 a matching, circumferential detent spring 43 through the outer wall the dust box 36 is formed.
  • the dust inlet nozzle 35 goes to the left in the viewing direction - i.e. to the rear at the bottom in a floor 39 and laterally in side walls 42 ( Figure 7) about.
  • the bottom 39 sits on a transverse one lower locking groove 41 leading further back in a floor 47 of a suction unit 48, which is a motor 50 with upper and lower fan 52, 54 contains and rear is completed by a rear wall 421. This goes above in a further detent spring 43 over that of the detent groove 41 of a motor cover 45 is overlapped.
  • the motor cover 45 is to the right in the viewing direction angled below and wearing in the angled, with openings 450 provided partition 44 a microfilter 46, the the openings 450 serving as air outlet openings permeable to air, grips dust-retaining.
  • the dust outlet connection 28 carries contact rails 30 at the top, each in a bent, leaf spring-like contact tongue 32 ends with those on top of the dust inlet connection 35 seated contact tabs 34 can be coupled.
  • the contact flags 34 lead electrically behind to the motor 50, while the contact rails 30 forward into the interior of the Housing 12 to a power supply device, e.g. one lead unspecified battery or transformer.
  • the dust box 36 is at the dust outlet connection 28 of the hand power tool 10 via locking means 37 ( Figure 2) releasably locked.
  • Figure 1 shows that the dust inlet port 35 is a chassis-like Forms part of the dust box 36, to which the dust box bottom 39 or 47, connect side walls 42 and rear wall 421.
  • the box thus formed which is open at the top, can be closed, by first the motor cover 45 with its right angle facing downwards, carrying the microfilter 46 Partition 44 engages by means of tongue and groove connection 41, 43 is attached. Then the dustproof cover 38 with its locking groove 41 over the locking springs 43 of the dust inlet connector 35 or the side walls 42 and the partition 450 clipped in.
  • the engine cover 45 can be common only then with the partition 450 and the filter 46 the dust box 36 can be released if the cover 38 is removed beforehand has been. This is an unwanted opening of the engine cover 34 practically excluded and collected in the dust box 36 Grinding dust does not get to the motor 50 because he normally emptied after opening the lid 38 has been.
  • Dust residues still attached to the microfilter 46 are removed during removal of the engine compartment cover 45 rather into that facing away from the engine 50 Side of the dust collection chamber than enter the engine compartment fall. They therefore pose no danger to the engine 50 and can easily be done by tapping adherent Grinding dust can be freed.
  • Closing the lid of the dust box 36 is in reverse Sequence easy to accomplish as when emptying.
  • FIG. 2 shows handheld power tool 10 according to FIG. 1 in a view from above, with the previous ones FIG. 1 does not explain reference symbols again shall be. It goes beyond Figure 1 the upper, airtight lid 38 of the dust box 36 is clearly recognizable, and the engine cover 45 with the air outlet holes 440th
  • Figure 3 shows a plan view of the dust box 36, with about Figures 1 and 2 going beyond the microfilter 46 and Contact tabs 34 in the area of the inlet connector 35 in particular are clearly recognizable.
  • the one designed as a pleated filter Microfilter 46 protrudes into the center of the dust box 36.
  • FIG. 4 shows the dust box 36 without a dustproof cover 38 and without engine cover 45 from above and the engine 50 with its Electrical connecting cables 51 merging into contact tabs 34.
  • the motor 50 has holding arms 49. This are screwed with projections 420 of the side walls 42.
  • Figure 5 shows a plan view of the motor cover 45 with the upper air outlet holes 440 and the angled down in the drawing plane extending partition 44 with the holes 450 area with the microfilter 46.
  • Figure 6 shows the cross section of the inlet channel 35 and the Design of the contact lugs 34.
  • FIG. 7 shows a cross section of the dust box 36 with a view in FIG the inside of the box 36 with a view of the front side wall 42 with the dust inlet connection 35.
  • Figure 8 shows a cross section of the dust box 36 in the area of the engine 50 with the engine cover 45 with its upright extending downward, carrying the microfilter 46 Area 44 with the holes 450. It can also be seen that the Motor 50 with its fans 52, 54 in its own housing sits with bracket arms 49, by means of which he attaches himself to the Cantilever 420 is supported or anchored thereon.
  • FIG. 9 shows an enlarged section of the one in FIG. 1 of an enclosed area between the dust outlet pipe 28 and dust inlet connection 35, being clear the contact tabs fixed to the top of the dust inlet connection 35 34 and the machine-side electrical contact rail 30 with its curved contact tongue 32 can be seen.
  • Figure 10 shows an enlarged section of the with the engine cover 45 connected side wall 47 of the dust box 36.
  • Figure 11 shows an enlarged section of the one Circle surrounding area of the dust inlet connection 35 according to Figure 6, the fixed points 58 in the form of thermal deformed plastic tabs fixing the contact tabs 34 58 are recognizable.
  • Safety valve In the dust inlet connection 35 of the dust box 36 is a not shown Safety valve arranged. This will formed by elastic flaps that are automatically resilient close and open the air flowing in become and an unhindered entry of Allow grinding dust. The ones that close without air flow Valve flaps of the safety valve prevent the unwanted discharge of collected grinding dust through the Dust inlet nozzle into the dust outlet tube or with the dust box removed to the outside.
