Definitions

  • the invention relates to a suction device for separating particles from a suction flow, according to the preamble of claim 1.
  • Such a suction device is, for example, off US 2010/0199453 A1 known.
  • a suction device sucks in particles via a suction hose, the suction hose in turn being able to be connected to an electric hand machine tool in order to suck up dust or particles generated by this hand machine tool when machining a workpiece, for example sawing or drilling.
  • a suction device listens, so to speak, whether its performance is required. For example, a power cord of the hand machine tool can be plugged into a socket of the suction device. A current sensor measures whether the hand machine tool draws current via the socket, which indicates that the hand machine tool is in operation. The suction device then switches on. In this way, the hand machine tool can influence the operation of the suction device. In practice, however, problems arise every now and then if, for example, a filter of the suction device is clogged or clogged in such a way that the suction of the particles, which the hand machine tool generates, is no longer satisfactory.
  • the external communication device according to the invention for interaction with a hand machine tool and communication with the suction device communication device of the suction device according to the invention forms part of the hand machine tool or a module that can be connected to the hand machine tool and is designed according to the technical teaching of claim 8.
  • the external communication device can also be arranged, for example, at an end of a suction hose remote from a housing of the suction device.
  • the suction hose is connected to the hand machine tool, so that the external communication device, e.g. configured as a module, is also connected to the hand machine tool.
  • the external communication device and the suction device communication device communicate with one another wirelessly or wirelessly.
  • a line and / or further wireless communication can then be provided between the external communication device and the hand machine tool, for example its control device.
  • the suction device influences the hand machine tool, so to speak, which has an external communication device for this purpose, for example there outputs a message about a current operating state of the suction device and / or the external device, the hand machine Machine tool, controls directly.
  • control signal it is possible for the control signal to switch off the hand machine tool or to reduce its power when the power of the suction device falls below a certain limit value, for example because a filter of the suction device is clogged or the like.
  • the message signal is suitable, for example, for activating an output device on board the external communication device and / or the hand machine tool in order to indicate an operating state of the suction device. So if, for example, the suction power is not sufficient, for example an illuminated display, in particular an LED, can be activated. If the operating state of the suction device is suitable for safe operation and / or proper suction of the particles in the work area of the hand machine tool, a green LED lights up, for example, otherwise a red LED. If the operating status of the suction device is critical, a yellow LED can light up.
  • a preferred embodiment of the invention provides that the suction device communication device can also receive messages or signals from the external communication device.
  • the suction device can influence the hand machine tool or send messages to it, but also, conversely, the hand machine tool can influence the suction device, for example to control it to output information from the hand machine tool and / or to influence an operating state of the suction device .
  • the hand machine tool can increase, decrease or the like the suction power.
  • the external communication device expediently communicates directly with a control device of the hand machine tool or forms part of such a control device.
  • the communication can provide that signals or information received by the hand machine tool control device are sent from the external communication device to the suction device.
  • the external communication device forwards information, messages, signals or the like received from the suction device in the direction of the control device and / or controls the control device directly, for example to increase or decrease a speed of a drive motor of the hand machine tool, to block the Drive motor if the suction power of the suction device is too low, or the like.
  • An advantageous method provides that the suction device communication device sends at least one identification code and / or one operating parameter to the external communication device and / or receives at least one identification code and / or one operating parameter from the external communication device, and that the suction device and / or the hand machine tool can execute at least one function based on the at least one identification code received in each case and / or the operating parameter received in each case.
  • the hand machine tool logs on to the suction device and / or vice versa and, in this context, sends an identification code and / or an operating parameter to the respective other device. Based on this information, an initialization is possible in such a way that, for example, the suction device then sets its operating mode so that it matches the hand machine tool. If, for example, the tool is a hand saw that produces a large amount of particles when sawing into a workpiece, the vacuum cleaner will set a correspondingly higher suction power.
  • the cleaning of a filter of the suction device can then take place correspondingly more frequently, that is to say that a cleaning interval, for example with a circular saw, is significantly shorter than, for example, with a jigsaw, which generates fewer particles during its operation.
  • the hand machine tool can of course be designed differently, for example, it can comprise a drill, a saw, in particular a circular saw, plunge-cut saw or the like.
  • the device receiving an operating parameter or an identification code i.e. the suction device or the hand-held machine tool
  • adjusts its subsequent functioning based on the received identification code or the received operating parameter so that, for example, the suction device adjusts itself to the hand-held machine tool and accordingly, for example, does not allow the suction power to drop below a minimum or to rise above a maximum.
  • sensitive surfaces e.g. a grinding or polishing machine
  • too high a suction power can be a hindrance.
  • insufficient suction power, a clogged filter or the like on the part of the suction device can also lead to undesirable adverse effects on the environment, i.e.
  • the invention can provide a remedy here in that the suction device virtually detects which hand machine tool is connected and accordingly sets its operating parameters or working parameters.

  • the criterion can be, for example, a safety criterion, an environmental criterion, an occupational safety criterion or the like.

This protects the user.

  • At least one communication line 300 for example an electrical line and / or an optical conductor, runs in the suction hose 18 for this purpose, to which on the one hand, for example, the suction device communication devices 40 and / or the control device 37 or another component on board the suction device 10 is connected to communicate with the hand machine tool 80 or 180.
  • the external communication device 150 or 250 can be connected to the at least one communication line 300.
  • the external communication device 150 or 250 sends the identification code 460 that identifies the hand-held machine tool 80 to the suction device 10.
  • the suction device communication device 40 receives the identification code 460 and forwards it, for example, to the control device 37, which uses the identification code 460 to identify, for example, the type of hand machine tool 80, for example which amount of particles is to be expected from this hand machine tool 80 and which suction power accordingly is to be provided by the suction device 10 or the like.
  • the control device 37 accordingly sets the function of the suction device 10, for example in such a way that the suction power of the suction motor 19 can be set on the setting switch 24, but not below a limit value that enables reliable suction of the particles generated by the hand machine tool 80 .
  • control device 37 it is also possible for the control device 37 to check whether operation of the hand machine tool 80 with the suction device 10 is even possible, so that at least one criterion is met. If, for example, it should be noted that the suction device 10 is intended to provide explosion protection in connection with the respective hand machine tool and / or at least a predetermined suction power of the suction device 10 is required so that the at least one criterion is met, the control device 37 can determine whether the identification code 460 is specified in a table 430 which contains several identification codes. If this is the case, the control device 37 enables the suction device 10 for operation with the hand machine tool 80.
  • the type of particles can also be different, for example comprise larger chips or smaller chips. Accordingly, it is expedient if the hand machine tool 80 sends information about the tool 82 used to the suction device communication devices 40 or 140, for example as an operating parameter 450. Depending on the nature of the particles that the operating parameter 450 then represents, the control device 37 can, for example, set cleaning intervals of a cleaning device 9 that cleans a filter 8 upstream of the suction motor 19.
  • the suction device communication device 40 sends an identification code 410 of the suction device 10 and / or at least one operating parameter 400 to the hand machine tool 80.
  • a controller 88 on board the hand machine tool 80 uses a check table, for example, to check whether the identification code 410 classifies the suction device 10 in such a way that it can be used in connection with the hand machine tool 80. Only then does the controller 88 enable the drive motor 81. Otherwise, the controller 88 blocks the drive motor 81, so that, for example, adverse health effects of a user of the hand-held machine tool 80 due to particles that have not been extracted can be avoided.
  • the suction device 10 can, for example, communicate to the hand-held machine tool 80 which suction power can be available.
  • the hand machine tool 80 then reduces, for example, a maximum speed of the drive motor 81, so that even at the highest speed of the drive motor 81 that can be set at the switch 87, the suction power of the suction device 10 is sufficient to reliably remove all particles or at least essentially all particles from the working area of the hand -Suction machine tool 80.
  • the external communication devices 150 or 250 and / or the suction device communication devices 40 or 140 can directly generate control signals and / or message signals based on the respective received identification code if the 410, 460 and / or the received operating parameters 400, 450 and to the other Send communication devices.
  • the external communication devices 150 and / or 250 can use the identification code 410 to determine, for example, that the suction device 10 has to provide a specific performance and accordingly sends a control signal 351 that the suction device 10 instructed to set a specific power level as a minimum power level that can be set on the setting switch 24.
  • a message signal 352 can also be generated, which is displayed by the display 102, for example.
  • the suction device 10 or the suction device communication devices 40, 140 can also be configured in this way.
  • the suction device communication devices 40, 140 and / or the suction device 10 for example the control device 37, use the identification code 460 or the operating parameter 450 to determine which speeds of the drive motor 81 of the hand machine tool 80 are to be set or can be set and accordingly sends a control signal 353 and / or a message signal 354 to the external communication devices 150 or 250.
  • the control signal 353 instructs them to notify the control device 88, for example, of which outputs of the drive motor 81 should be adjustable at the switch 87.
  • the information in the message signal 354 is displayed on the display 104, for example, so that the operator knows which power ranges are preferably to be set on the hand machine tool 80 and / or which tools can be used or the like.
