Definitions
- Dust generating power tools are used to reduce health To rule out hazards as far as possible, additional suction devices used.
- the dust extraction device is in one certain distance from the power tool and is through with it connected a suction hose.
- a suction hose From DE-OS 37 10 619 it is already known, in a power tool with a dust extraction device, which are connected in parallel to a power source are, by measuring the power consumption of the power tool turn this on or off.
- dust Power tools With large amounts of dust Power tools, however, are heavily soiled the vacuum cleaner, so that this and that Switch off the electrical device automatically. The operator must then interrupt their work, go to the dust extractor, mostly descending from a ladder and the Press filter cleaning. Only after filter cleaning has been completed can then go back to the power tool and continue the work with it.
- very large amounts of dust arise continuously not only work breaks but also unnecessary ways between the corresponding devices.
- the object of the present invention is at one described power tool the paths between this and to avoid the suction device in a simple manner.
- This is achieved according to the invention in that the dust extraction device provided with a filter cleaning and one in particular longer delayed delay, in the event of a power failure in the Power tool circuit turning filter cleaning on Switching device is provided. Every time you switch off the tool is now cleaned without filter special switches are operated on the dust extraction device have to. The operator can therefore during the entire Work process remain in the workplace and the filter cleaning by switching the power tool on and off, so operate by remote control. It is useful in the circuit of the filter cleaning in Row with the switch-on one when current flows in the circuit the dust extraction device effective shutdown device provided.
- the drawing shows a schematic representation of a circuit for a power tool with dust extraction device and Filter cleaning.
- the power plug 1 is used to connect to a not shown Power source. It is via a switch 2 and the lines 3 and 4 connected to a dust extraction device 5. In parallel, two electromagnets 6 and 7 are one Vibrating device 8 is provided for the dust extraction device 5. The switch 2 also turns on the power supply 9 for electronics 10 connected to the power plug 1. In parallel to the power plug 1 is in front of the switch 2 on the Lines 11 a socket 12 for a not shown Power tool switched.
- a voltage converter 13 with an amplifier unit 14 is arranged, which, depending on the current flow, the electronics 10 controls.
- This has a selector switch 15 with three positions on, in the top position a purely manual operation of the power tool, the dust extraction device 5 and the Vibrating device 8 is possible. The middle position is for automatic mode and the third for manual shaking the vibrating device 8 is provided.
- the further switch 16 serves as a switching device for the vibrating device 8 and is from the vacuum of the dust extraction device 5 and thus from the pollution of the filter, not shown, controlled.
- a triac 17 and 18 are switched on. Both Triacs are controlled via the electronics 10.
- the switch 16 is closed, so that the vibrating device 9 via a further delay switching element Electronics 10 on the triac 18 is voltage. Through a The electronics 10 then becomes the vibrator 8 preferably switched off again after ten seconds. at heavy filter contamination and thus closed switch 16 can thus via the power tool connected to the socket 12 the vibrating device 10 by multiple inputs and Switch off the same be operated.
