Definitions

the invention relates to a suction device for separating particles from a suction flow, with a suction motor for generating the suction flow and with a suction housing in which the suction motor and a dust collection chamber for collecting particles separated from the suction flow are arranged, the suction device for sucking up Operation of a hand-held machine tool having a drive motor for driving a tool is provided for accumulating particles.
the invention also relates to an external communication device for interaction with a hand-held power tool and communication with such a suction device.
Such a suction device is made, for example DE 10 2009 015 642 A1 famous.
the suction device sucks in particles via a suction hose, the suction hose in turn being able to be connected to an electric hand-held power tool in order to suck off dust or particles generated by this hand-held power tool when machining a workpiece, for example sawing or drilling.
a suction device usually listens in, so to speak, to whether its performance is required. For example, a power cord of the handheld power tool can be plugged into a socket on the suction device. A current sensor measures whether the Hand machine tool current relates to the socket, which indicates operation of the hand machine tool. The suction device then switches on. In this way, the handheld power tool can affect the operation of the suction device. In practice, however, problems occasionally arise if, for example, a filter of the suction device is clogged or clogged in such a way that the suction of the particles produced by the hand-held power tool is no longer satisfactory.
a suction device of the type mentioned at the outset is provided with a suction device communication device for communication with an external -Has communication device, wherein the suction device communication device has a suction device transmitter for sending at least one control signal and / or message signal to the external communication device.
the external communication device according to the invention for interaction with a hand-held power tool and communication with the suction device communication device of the suction device according to the invention forms part of the hand-held power tool or a module that can be connected to the hand-held power tool and has an external receiver for receiving the control signal and/or or notification signal from the suction device communication device and/or an external transmitter for sending at least one control signal, in particular a wireless control signal and/or notification signal to the suction device communication device.
the external communication device can also be arranged, for example, at an end of a suction hose that is remote from a housing of the suction device.
the suction hose is connected to the hand-held power tool, so that the external communication device, e.g. designed as a module, is also connected to the hand-held power tool.
the external communication device and the suction device communication device communicate with one another wirelessly or without wires.
a line and/or further wireless communication can then be provided between the external communication device and the handheld power tool, for example its control device.
the suction device influences the hand-held power tool, so to speak, which has an external communication device for this purpose, for example outputs a message there about the current operating status of the suction device and/or the external device, the hand Machine tool, directly controlled.
control signal it is possible for the control signal to switch off the hand-held power tool or reduce its power if 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 means on board the external communication device and/or the hand-held power tool in order to indicate an operating state of the suction device. So if, for example, the suction power is not sufficient, for example a light 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-held power tool, a green LED lights up, for example, otherwise a red LED. If the operating condition of the vacuum cleaner is critical, a yellow LED may illuminate.
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 influence the hand-held power tool or send messages to it, but also, conversely, the hand-held power tool can influence the suction device, control it, for example, to output information from the hand-held power tool and/or to influence an operating state of the suction device .
the handheld power tool can increase or decrease the suction power or the like.
the external communication device expediently communicates directly with a control device of the handheld power tool or forms part of such a control device.
the communication can provide for signals or information received by the control device of the handheld power tool to be 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 the speed of a drive motor of the hand-held power tool, to block the Drive motor when 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 identifier and/or one operating parameter to the external communication device and/or receives at least one identifier and/or one operating parameter from the external communication device, and that the suction device and/or the hand-held power tool can perform at least one function based on the at least one identifier received and/or the operating parameter received in each case.
the handheld power tool logs on to the suction device and/or vice versa and in this context sends an identifier and/or an operating parameter to the other device in each case.

the criterion can be, for example, a safety criterion, an environmental criterion, an occupational safety criterion or the like. If, for example, the suction device cannot suck up particles to a sufficient extent, it is possible that the suction device and/or hand-held power tool will block subsequent operation. This protects the user.
the suction device and/or the hand-held machine tool expediently have an output device or several output devices in order to output, for example, at least one operating parameter and/or at least one identifier and/or the above at least one criterion.
the output means can also advantageously indicate whether and under what conditions the operation of the pairing consisting of suction device and hand-held power tool that meets the at least one criterion is possible. The operator thus receives feedback as to which information is exchanged and/or how later operation is possible. If, for example, the suction device and the hand-held power tool match one another, a green indicator light or the like, for example, can be activated as an optical output means.
Such an output means can be provided on the hand-held power tool and/or on the suction device, for example on the suction device communication device and/or on the external communication device.
a preferred embodiment of the invention provides that the suction device and/or the hand-held power tool is designed in this way are that they block operation with the other device if at least one criterion cannot be met. If, for example, the suction device detects that the hand-held power tool would produce too many particles that cannot then be extracted, the suction device can block its operation. The hand-held power tool can also block an operation if the criterion cannot be met or is not met.
the suction device and/or the hand-held power tool are designed to have one or set several parameters for a function of the suction device or the hand-held power tool according to the at least one criterion.
the suction device can adapt its suction power to the hand-held power tool.
the hand-held power tool is also advantageously designed such that it can only be used in such a speed range or working range, for example, that the suction device is still able to suction off particles to an extent corresponding to the criterion.

the identifier can be designed as such an identifier that it uniquely identifies the suction device or the hand-held power tool, which operating data of the hand-held power tool or suction device, for example performance data, performance requirements or the like, can be derived from the identifier.
the identifier can indicate the respective type of suction device or hand-held power tool.
a unique identifier that occurs only once worldwide, so to speak, is also possible.
the identifier can also be in several parts, so that it includes, for example, a type identifier of the respective device on the one hand and a unique serial identifier or serial number on the other.
the at least one operating parameter is, for example, a machine tool operating parameter of the hand-held machine tool, which represents a possible or current operating state when the hand-held machine tool is being operated.
the operating parameter represents a maximum particle quantity that typically or currently occurs during operation of the hand-held power tool, a typical nature of the particles, or the like.
An operating parameter assigned to the suction device expediently forms a suction device operating parameter that represents an operating state that is currently or possibly occurring during operation of the suction device.
the suction device operating parameters or the suction device identification code can indicate, for example, a suction power of the suction motor and/or a maximum size of the suction flow and/or a remaining absorption capacity for particles in the dust collection space or in a filter inside the dust collection space.
the suction device is expediently designed to set at least one function of the suction device and/or the handheld power tool using the at least one identifier and/or the operating parameter.
This can be an identifier that has been received or is to be sent, or an operating parameter that has been received or sent.
the suction device is designed to set its own function on the suction device itself based on the operating parameters received from the hand-held power tool or the identification code, for example a suction power of the suction motor, a size of the suction flow, a cleaning function for cleaning a filter or the like.
the suction device is advantageously configured as a device that controls the hand-held power tool.
the suction device communication device is designed, for example, to send a control signal and/or report signal formed based on the received operating parameters and/or based on the received identifier to the external communication device, which is connected to the hand-held power tool or forms part of the hand-held power tool.
a control signal for example, a function of Hand machine tool are controlled, for example the drive motor of the hand machine tool.
the notification signal is suitable, for example, for outputting information determined by the suction device communication device or the suction device, for example a warning.
the aforementioned acoustic and/or visual output means are expedient for this.
the suction device expediently has an output means arranged on the suction device, for example its housing, or on board the suction device communication device for outputting information determined based on the received operating parameters and correctly or the received identifier.
the suction device can indicate acoustically or visually when the hand-held power tool can be operated together with the suction device.

the function, the external communication device for example, based on a received or on board the Adjust handheld power tool existing operating parameters as well as using an identification code received from the suction device or the identification code of the handheld machine tool.
the external communication device is expediently for sending a control signal formed on the basis of the received operating parameters or the received identifier for setting at least one function of the suction device, for example for setting a suction power of the suction motor, a size of the suction flow or volume flow, intervals of cleaning function of the suction device or the like , designed. It is also advantageous if the external communication device is designed to send a notification signal to the suction device communication device to output information, for example a message. This information is determined, for example, by the external communication device or the suction device or both in interaction with one another.
the external communication device is advantageously designed to receive an identifier or the operating parameter from a control device of the hand-held power tool.
the control device of the handheld power tool thus determines the identifier or the operating parameter and sends this to the external communication device for further processing.

the external communication devices 150 and 250 can be integral components of the energy storage module 90 or of the hand-held power tool 80 .
a modular concept is also possible, which means that there is a module receptacle on hand-held power tool 80 and/or on energy storage module 90, for example, in which the external communication devices 150 or 250, which are designed in a correspondingly modular manner, for example as plug-in parts, can be arranged.
the external communication devices 150 and/or 250 can also be arranged subsequently on the energy storage module 90 or the hand-held power tool 80 by means of fastening means, for example adhesives, latching connection means or the like. Retrofitting is therefore possible.
the external communication device 150 includes, for example, a speed sensor 153 that detects a particular speed of the drive motor 81 . So when the drive motor 81 and thus the hand-held power tool 80 is operated, the speed sensor 153 controls an external transmitter 155s, which includes a Bluetooth transmitter, for example, for sending control signals 151 via an antenna 156, which can be installed, for example, in the machine housing 83 is integrated, whereupon the suction device communication device 40 switches on the suction motor 19 or sends a switch-on signal to the control device 37 . If the speed of the drive motor 81 increases, ie the tool 82 generates even more dust when processing the workpiece W, the external communication device 150 can control the suction device communication device 40 to increase the speed of the suction motor 19 . When the hand-held power tool 80 is switched off, the external communication device 150 triggers the suction motor 19 to be switched off.

an external communication device can of course also have several sensors, switching contacts and the like, so that it generates the control signal as a function of at least two sensor signals or signals from switching contacts.
the external communication device 150 evaluates the sensor signals of the sensors 153 and 153' and only sends the control signal 51 to switch on the vacuum motor 19 when both sensors 153 and 153' report that the drive motor 81 of the hand-held power tool 80 is running.
the suction device 10 continues to run for a fixed or preferably parameterizable run-on time, i.e. the suction motor 19 is also switched off only after a certain time, when the hand-held power tool 80 is already switched off.
the suction motor 19 is also switched off only after a certain time, when the hand-held power tool 80 is already switched off.
Switching on the suction motor 19 immediately when the control signal 51 indicates switch-on is also not always advantageous. For example, there may be an incorrect operation or the hand-held power tool may not yet be in engagement with the workpiece W. Accordingly, it can be advantageous if a switch-on delay time is also permanently set or parameterized for the suction device communication device 40, so that it only switches on the suction motor 19 after the switch-on delay time has expired, if it is activated by the Control signal 51 for switching on the suction motor 19 has been activated.
the external communication device 250 forms part of the energy storage module 90 and includes a current sensor 253, which includes a current flow from the energy storage module 90 to the hand-held power tool 80, in particular its drive motor 81.

the intermediate module 100 is indicated.
a preferred embodiment provides that a suction device communication device and an external communication device, which communicate wirelessly with one another, become acquainted as it were within the framework of a learning process, for example a so-called teach function.
the external communication device 50 first sends a communication identifier as part of a start procedure 59 to the suction device receiver 41r, which in turn uses a comparison list, for example, to check whether the communication identifier 59 authorizes the external communication device 50 to send the control signals 51. If, for example, several craftsmen are working on a construction site and switch suction devices on and off wirelessly with their hand tools according to the invention, it is thus possible to prevent disruptions from occurring.

the charging module 60 can also have or form a suction device communication device according to the invention, for example a suction device communication device 140.
messages can also be sent in the direction of communication from the hand-held power tool to the suction device, so that, for example, an operating state of the hand-held power tool 80 can be displayed on board the suction device 10 .
the external communication device 150 can indicate a malfunction in the hand-held power tool 80 as part of an external transmitter 155s as a notification signal 101 to the suction device communication device 40, which in turn then receives the notification signal 101 via a suction device receiver 41r and, for example, a visual display 102, for example an LED, for displaying the notification signal 101 drives.
Wireless communication is also expedient between the external communication device 250, which is on board the energy storage module 90, for example, and the charging module 60, which includes the suction device communication device 140.
the external communication device 250 can use an external transmitter 255s to report the state of charge of the energy storage module 90 to the charging module 60 , ie the charging device 61 , using a status signal 201 .
the suction device communication device 140 receives the notification signal via a suction device receiver 141r.
a visual and/or acoustic display 103 can be provided on board the charging device 61, which displays the state of charge of the external energy storage module 90 operated on the hand-held power tool 80.
the external communication device 250 comprises, for example, a measuring device 257 for detecting the state of charge of the energy storage module 90 and for generating the status signal 201 reporting the state of charge.
the aforementioned wireless concept can also be used in the opposite direction, which means that the suction device communication devices 40, 140 send messages or signals to the external communication devices 50, 150, 250.
suction device transmitters 41s and 141s are provided, which are designed to transmit control signals and/or notification signals to the external communication devices 50, 150, 250.
the suction device transmitter 41s can send a notification signal 105 to the external communication device Send 50, which outputs the content of the message signal 105 to optical or acoustic output means 106, for example, include an LED.
the operator can use this signal output, which takes place directly on site at the hand-held power tool 80, to recognize that he has to empty the collection container of the suction device 10, for example.
the control device 37 can therefore generate a notification signal 105 or a message using the suction device communication device 40, which this sends to one or more of the external communication devices 50, 150 or 250 via the suction device transmitter 41s.
Message signal 105 which, as indicated, can also be a more complex message containing a number of pieces of information or can also include a number of separate messages, contains, for example, information about the size of suction flow 20 and/or a suction power of suction motor 19 and/or information about the filling level of the dust collection chamber 15.
the external communication devices 50, 150 or 250 can output one or more items of information of the message signal 105 to output means 106, for example, which include, for example, an indicator light, for example LEDs, and/or a display and/or a loudspeaker or other acoustic output means. If, for example, the notification signal 105 signals that the dust collection chamber 15 and/or a filter arranged therein (not shown in the drawing) will soon be completely full and dirty, an illuminated display 107, configured as a warning LED, of the external communication device 50 can indicate this, for example .
the external communication device 150 or 250 arranged on board the energy storage module 90 or the intermediate module 100 or the hand-held power tool 80 can also, for example, also include a haptic display, a vibration display or the like in order to output the notification signal 105 .
a haptic display for example, an optical and/or acoustic display 104 and/or a vibration element 109 can be provided as an output means on board hand-held power tool 80, Is signaled as part of the message signal 105 vibrates and thus indicates to the operator that he should take care of the suction device 10 so that the suction power desired by him is available.
a function that goes even further is when the suction device 10 and/or the suction device communication devices 40 or 140 directly influence the function of the hand-held power tool 80 with the aid of a control signal 108 .
the control device 37 can send information 147 to the suction device communication devices 40 or 140, from which the corresponding control signal 108 is generated and to the external communication devices 50, 150 , 250 sends.
the external communication devices 150 or 250 can then directly influence the operation of the handheld power tool 80 .
the control signal 108 can instruct the power of the drive motor 81 to be reduced or even to be switched off completely. In this way, it can be avoided, for example, that the health of the user is damaged by particles whirling around if the suction device 10 can no longer adequately suck off the particles produced by the hand-held power tool 80 .
the external communication device 250 located on board the energy storage module 90 can, for example, switch the current flow to the hand-held power tool 80 off and on by means of a switching device 258, e.g. after activation by the control signal 108.
External communication device 250 can also have a wired or preferably wireless interface 259, e.g. a radio interface, for communication with handheld power tool 80, in particular its controller 88, e.g. to forward control signal 108 and/or operating parameters 450, 400 and/or to communicate the identifiers 410, 460.
a wired interface 259 can provide, for example, for data to be digitally transmitted and/or modulated via the supply lines to the handheld power tool 80 .
the external communication device 150 is connected directly to the controller, for example on-board electronics, of the handheld power tool 80 or forms part of the same, so that it can directly influence the operation of the drive motor 81 in this way, i.e. it can be switched off, for example . It is of course advantageous if a warning is given beforehand, so that the operator is not surprised by the aforementioned forced shutdown.

the charging voltage L is, for example, a DC voltage in a range from 5 V to 25 V.
the charging module 60 has identification means 66 in order to identify the respective type of energy storage module 90 and set the charging voltage L accordingly.

the detection means 66 comprise, for example, electrical means, optical means or the like. It is also possible for the detection means 66 to comprise a bus interface, for example, in order to communicate with a bus coupler on board the energy storage module 90 and thus record data from the energy storage module 90, for example its state of charge, nominal voltage or the like.
the charging device 61 can convert a supply voltage V provided, for example, by the supply network N to the charging voltage L.
monitoring means 75 are advantageously provided for monitoring the charging voltage L and/or for monitoring a state of charge of the energy storage module 90 so that it is optimally charged.

a holder of the type of holder 63 and charging contacts of the type of charging contacts 65 can also be arranged at another location on the suction cup housing 11, for example at the top in the area of the receptacle 28, where the energy storage module to be charged can be accommodated in a protected manner, i.e. less exposed than in the area of control panel 22.
the suction device communication device 140 formed by the charging module 60 has, for example, a suction device receiver 141r.
the charging module 60 is supplied with electrical energy, for example a supply voltage V, via the module contacts 36 .
the charging module 60 When the charging module 60 receives a control signal 51, 151, 251 for switching on the suction motor 19 via its suction device receiver 141r and an antenna 146 integrated, for example, in the charger housing 62, it starts charging the energy storage module 90, i.e. it generates the from the supply voltage V the charging voltage L, so that a charging current I flows. An input current E required to provide the charging current I is detected by the current sensor 49. The suction device 10 therefore recognizes that an electrical consumer requires electricity and then switches on the suction motor 19 in a manner known per se.
suction device communication device 140 or charging module 60 reduces the power supply to energy storage module 90 or switches off the charging process, so that on the input side (supply voltage V) no input current E that can be detected by the current sensor 49 or an input current E that is below a detection threshold flows and thus, for example, the control device 37 switches off the suction motor 19 .
the charging module 60 can simulate a network-connected electric hand-held power tool, which is supplied with electrical energy via the suction device 10 - which, however, is not actually the case.
the charging device 61 can be supplied with electrical energy from the energy store 26 on board the suction device 10 .
the control device 37 controls the provision of electrical energy at the module contacts 36. It is preferably provided that the control device 37, for example, lowers the power output at the module contacts 36 when the naturally aspirated motor 19 is running, and then increases it again. Thus, for example, a power pack of the suction device 10 that provides the charging voltage L is less heavily loaded.
the suction device communication devices 40 and/or 140 located on board the suction device 10 or connected to it and the external communication devices 50, 150, 250 are also suitable for a registration procedure in which the suction device 10 has at least one operating parameter 400 and/or at least an identifier 410 to the external device, e.g. hand-held power tool 80 and/or its energy storage module 90 and/or in the reverse direction to the device to be connected to suction device 10, e.g.
hand-held power tool 80 or its energy storage module 90 at least one operating parameter 450 and /or sends at least one identifier 460 to the suction device 10 so that only matching pairs of suction device and hand-held power tool are used and/or the operating parameters of the suction device 10 and the hand-held power tool 80 or 180 are set such that optimal operation the respective hand-held power tool 80 or 180 on the suction device 10 is possible.
the procedure described in detail below can be used to prevent the suction device 10 from being used in connection with the hand-held power tool 80 .
the suction power is sufficient for hand-held power tool 180, for example, suction device 10 and hand-held power tool 180 can be used together.
suction device 10 and the respectively connected hand-held power tool 80 or 180 to coordinate their respective performances with one device registering with the other device and/or vice versa.
At least one communication line 300 for example an electrical line and/or an optical conductor, runs in the suction hose 18, to which, 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 handheld power 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 identifier 460 identifying the hand-held power tool 80 to the suction device 10.
Suction device communication device 40 receives identifier 460 and forwards it, for example, to control device 37, which uses identifier 460 to identify, for example, the type of hand-held power tool 80, for example what particle quantity is to be expected from this hand-held power tool 80, and what 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 that the hand-held power tool 80 generates .
control device 37 can check whether operation of the handheld power tool 80 with the suction device 10 is possible at all, if 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 handheld power tool and/or at least a predetermined suction capacity of the suction device 10 is required for the at least one criterion to be met, the control device 37 can determine whether the identifier 460 is specified in a table 430 containing several identifiers. If this is the case, the control device 37 releases the suction device 10 for operation with the hand-held power tool 80 .
the type of particle can also be different, for example it can include larger chips or smaller chips. Accordingly, it is expedient if the handheld power tool 80 sends information about the tool 82 used to the suction device communication devices 40 or 140 as an operating parameter 450, for example. Depending on the nature of the particles, which 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 that is upstream of the suction motor 19 .
suction device communication device 40 sends an identifier 410 for suction device 10 and/or at least one operating parameter 400 to hand-held power tool 80.
a controller 88 on board the hand-held power tool 80 uses a check table, for example, to check whether the identifier 410 classifies the suction device 10 in such a way that it can be used in conjunction with the hand-held power tool 80 . Only then does the controller 88 release the drive motor 81 . Otherwise, the controller 88 blocks the drive motor 81 so that, for example, health problems for a user of the hand-held power tool 80 due to particles that have not been suctioned off can be avoided.
the suction device 10 can inform the hand-held power tool 80, for example, which suction power can be available.
the hand-held power tool 80 then reduces, for example, a maximum speed of the drive motor 81, so that even with the highest speed of the drive motor 81 that can be set at the switch 87, the suction capacity 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 -Machine tool 80 suction.
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 respectively received identifier if the 410, 460 and/or the received operating parameters 400, 450 and to the other Send communication devices.
identifier 410 assigns suction device 10 to a specific performance class
external communication devices 150 and/or 250 can use identifier 410 to determine, for example, that suction device 10 must provide a specific performance and accordingly sends a control signal 351 that causes 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 designed in this way.
the suction device communication devices 40, 140 and/or the suction device 10 for example the control device 37, use the identifier 460 or the operating parameter 450 to determine which speeds of the drive motor 81 of the hand-held power tool 80 are to be set or set and sends a control signal 353 accordingly and/or a message signal 354 to the external communication devices 150 or 250.
the control signal 353 instructs them to inform the control device 88, for example, which outputs of the drive motor 81 should be adjustable at the switch 87.
the information of the message signal 354 is displayed, for example, on the display 104 so that the operator knows which power ranges should preferably be set on the hand-held power tool 80 and/or which tools can be used or the like.
