Definitions
- the invention relates to a method for operating a cleaning device, wherein a user selects a cleaning activity to be carried out by means of the cleaning device via a communication interface of the cleaning device or via a communication interface of an external terminal in communication with the cleaning device, wherein the user selects at least one device setting of the cleaning device in order to carry out the cleaning activity Cleaning device and / or at least one device application of the cleaning device and carries out the cleaning activity with the device setting and / or device application made.
- the invention relates to a cleaning device with a communication interface, which is designed to carry out such a method.
- cleaning devices of the aforementioned type are known in the prior art. These are usually cleaning devices that are manually operated by a user and are preferably designed to carry out a number of different cleaning activities.
- the cleaning activities include, for example, hard floor cleaning, carpet cleaning, above-floor cleaning, wet cleaning and the like.
- essentially autonomous cleaning robots are also known in the prior art, which can be operated in different operating modes, for example.
- the user selects one of several cleaning activities that can be carried out with the cleaning device and then carries out certain device settings and/or device applications.
- the device settings include, for example, setting a power level of a blower or a speed of a rotating cleaning brush.
- a device application carried out by the user can, for example, be a certain speed of movement of the cleaning device over the surface to be cleaned or the connection of the cleaning device to a certain accessory.
- the accessories are, for example, a suction nozzle that can be detachably connected to a base device of the cleaning device, a mop attachment or similar.
- the user selects the device settings and/or device applications according to his or her own preference or judgment. If he needs help with this, he can access a manual for the cleaning device or look for help in an Internet forum that connects a number of users of similar cleaning devices.
- a method for operating a cleaning device according to the preamble of claim 1 is, for example EP-A-3108787 known.
- the user is provided with instructions for a plurality of steps to be carried out sequentially by the user via the communication interface, which include a device setting and/or device application, and wherein a tax - and evaluation device of the cleaning device or the external terminal corresponding to the step currently to be carried out monitors the actual execution of the device setting and / or device application and in the case that the device setting and / or device application actually carried out by the user is based on a predefined reference for the device setting to be carried out and/or device application differs, a notice is sent to the user.
- the user no longer has to search for help in manuals or forums for a cleaning activity to be carried out, but receives this directly from the cleaning device itself or from an external terminal that is in communication with the cleaning device.
- the cleaning device or the external terminal transmits instructions on how to carry out the cleaning activity to the user.
- the instructions contain a number of steps that the user must carry out.
- the instructions correspond to a step-by-step description of the procedure to be carried out by the user Carrying out the selected cleaning activity.
- the individual steps of the instructions can be output not only via the communication interface of the cleaning device itself, but alternatively also on an external device, for example a mobile device, in particular a mobile phone or tablet computer, or also on an external stationary device, such as a TV or similar.
- the instructions can provide the user with information on how to proceed in text form, as an image, video and/or voice output.
- the steps of the instructions communicated in this way can also provide implementation examples for the respective cleaning activity.
- the instructions themselves can be stored in a local memory of the cleaning device, a local memory of the external device or even a web server, for example on a server of the manufacturer of the cleaning device.
- the communication between the cleaning device and an external device and/or a web server preferably takes place via wireless data communication, for example within the framework of a WLAN network, via Bluetooth or via other wireless communication technologies.
- the user After receiving the instructions for carrying out the cleaning activity or after receiving a first step for carrying out the cleaning activity, the user carries out the first step.
- the user has to set a specific power level of a fan of the cleaning device as a device setting. Further possible device settings will be explained in more detail later.
- the step can alternatively or additionally include that the user has to execute a specific device application.
- the cleaning device must be guided over the surface to be cleaned, in particular in a sequence of back and forth movements and/or at a certain speed.
- a device application can further also involve the user connecting a certain accessory to the cleaning device, for example a suction nozzle that contains a rotating cleaning brush.
- the cleaning device has device-internal communication technology through which the control and evaluation device of the cleaning device gains knowledge of which settings or applications the user has made.
- the cleaning device has, for example, a plurality of detection devices, such as a contact sensor, which detects the connection of an accessory to the cleaning device, a power meter for detecting a power consumption of an electrical consumer, an acceleration sensor, which detects the back and forth movement of the cleaning device over a can detect cleaning surface or something similar.
- the control and evaluation device of the cleaning device can evaluate the measured values and compare them with a predefined reference, which is defined for the relevant step of the selected cleaning activity.
- the instructions for carrying out the cleaning activity or the first step of the instructions are sent to the user when the user has selected the cleaning activity.
- the user selects, for example, one of several cleaning activities displayed on a display, in particular a touchscreen, of the cleaning device or an external terminal and then presses a start button. He then receives instructions as to which device setting or device application he has to carry out in a first step of the instructions.
- the user can also start the instructions separately, that is, regardless of the time at which they select the cleaning activity, for example at the moment when he actually wants to carry out the cleaning activity. If the user has carried out a specified device setting and/or device application, it is checked whether the user has carried out the specified step according to the instructions.
- the user will be sent the next step in the instructions.
- There are therefore essentially two different reactions to the user's setting or application namely, on the one hand, a progression of the presentation if it is determined that the user has carried out the step correctly, ie the device setting or device application matches the predefined reference, and on the other hand stopping the presentation if the user's action deviates from the predefined reference for this instruction step.
- the control and evaluation device can issue a note about the detected deviation and ask the user to correct it.
- the user can also see a notice about a deviation from the instructions on the display of the cleaning device or the display of the external device. Overall, the user is guided step by step through the successive steps of the cleaning activity. This checks whether the user's implementation was carried out in accordance with the regulations.
- a detection device of the cleaning device measures a current amount of a device parameter of the cleaning device that is characteristic of the device setting and/or device application and communicates it to the control and evaluation device.
- a characteristic device parameter is set on the cleaning device, which can be measured by the detection device of the cleaning device and whose amount is compared with a corresponding reference amount or reference range.
- the detectable device parameters are measurable physical parameters, such as voltage, current, speed, frequency, speed, acceleration, force or similar.
- a distinction can also be made between the values “zero” and “one”, for example based on contact with an accessory, where "zero" indicates no contact with an accessory and "one” indicates contact with an accessory.
- a detection device of the cleaning device can, for example, also read out a code of an accessory and thus recognize which accessory from a plurality of available accessories has been connected to the cleaning device.
- control and evaluation device accesses a memory device in which a reference amount or reference range of the device parameter defined for the device setting and/or device application is stored, with the control and evaluation device including the measured amount of the device parameter compares with the stored reference amount or reference range.
- a reference range is specified for the device parameter for the comparison
- the measured device parameter can have a certain amount range. It is therefore not necessary for a measured device parameter to be absolutely identical to a single reference amount. Rather, a certain tolerance is included, which is taken into account when deciding whether the user has made a device setting and/or device application in accordance with the regulations.
- the steps to be carried out in succession are communicated to the user separately, so that the user is only informed of the device setting and/or device application of the next step of the instructions to be carried out.
- This design prevents the user from skipping instruction steps or incorrectly combined with each other.
- the user can concentrate on the next device setting to be carried out or device application to be carried out.
- it can be achieved that the user is only informed of a step in the instructions to be carried out later when the device setting and/or device application of the previous step carried out by the user matches the predefined reference for this previous step. According to this embodiment, it can be recognized at which point in time the user made an application error.
- the cleaning device is then kept in the status that corresponds to the incorrect device setting or device application. Incorrect use or non-optimal settings of the cleaning device can therefore be cleaned up in the best possible way and at the earliest possible time.
- the operation of the cleaning device or at least the execution of the selected cleaning activity is stopped and the user receives a message via a message about how he can proceed in order to make the cleaning activity a success.
- the user can preferably select a cleaning activity from a large number of different cleaning activities available on the cleaning device or the external terminal.
- An application is preferably installed on the cleaning device and/or the external terminal, which offers the user various alternatives for cleaning activities to be carried out.
- the cleaning activity can in particular be upholstery cleaning and/or mattress cleaning and/or carpet cleaning and/or vehicle interior cleaning and/or floor cleaning and/or stain removal and/or wet cleaning and/or wet cleaning and/or dry cleaning and/or carpet cleaning and/or hard floor cleaning and/or a Cleaning with the application of cleaning agents be.
- the execution of the cleaning activity also includes, for example, a large number of successive activity steps, which the user has to carry out individually as part of a separate step in the instructions.
- the cleaning activity “upholstery cleaning” may initially require a first step that involves connecting the cleaning device to a defined accessory.
- a subsequent step can be, for example, applying upholstery cleaning agent to the surface to be cleaned.
- a subsequent work step can then include tapping the surface to be cleaned. If the user has not already carried out the first step correctly, for example connecting the wrong accessory to the cleaning device, the instructions will not progress. Rather, the user is informed that there is an error and how it can be eliminated. Only after the user has connected the correct accessories do the instructions move on to the next step, namely applying upholstery cleaning agent.
- the device settings include, but are not limited to, a performance of an electrical consumer of the cleaning device, a delivery quantity of a liquid application device and/or cleaning agent application device, a speed or oscillation frequency of a soil processing element processing a surface, a position of a sealing element of a flow channel, a flow cross section a flow channel, and others.
- the device applications include, but are also not limited to, connecting the cleaning device to an accessory, in particular a suction nozzle and/or cleaning brush and/or a wiping element, applying a liquid to a surface to be cleaned, and moving the cleaning device over the surface to be cleaned , carrying out the cleaning activity over a certain period of time or others.
- a step of the instructions may also include a combination of one or more device settings and one or more device applications, such as operating a blower at a specific power level, connecting a specific accessory to a base device, and moving the cleaning device back and forth over the device being cleaned Area.
- the instructions with the chronologically sequential steps can be structured in a modular manner.
- each step that involves the user interacting with the cleaning device or an accessory can result in a plurality of alternative subsequent steps, with the subsequent step depending on how the user carried out the previous step.
- the next displayed step of the application depends on the evaluation result of the control and evaluation device, namely on whether the measured device parameters match a predefined reference.
- a decision is made as to which of the alternative subsequent steps will be presented to the user. This can be particularly relevant if the device parameters can occupy a certain parameter range. For example, with a measured value in an upper area of the reference range, a different subsequent step can occur than in the case of a device parameter in a lower area of the reference range.
- progression of the displayed steps can be delayed and remain in the status of the previous instruction step until the user makes corrections to the device application or device setting, that is, the measured data show that the requirements for the progress of the instructions or the cleaning activity is available.
- the invention also proposes a cleaning device with a communication interface, which is set up to carry out a previously described method.
- the cleaning device can not only have a communication interface to carry out the method, but also a control and evaluation device which monitors a device setting and/or device application by the user and the progress of the instructions or the issuance of a notice sent to the user.
- the cleaning device can also have a variety of different detection devices in order to measure a device parameter, which provides information about a specific device setting and/or device application.
- the cleaning device can furthermore be a device hand-held by a user or a device that operates essentially autonomously, in particular a cleaning robot that moves automatically.
- Figure 1 shows a user with a system consisting of a cleaning device 1 and an external terminal 4.
- the cleaning device 1 is designed here as an example as a cleaning device 1 that is manually operated by a user, namely, for example, a suction cleaning device.
- the cleaning device 1 is used to clean different surfaces, which can be, for example, hard floors, carpets, mattresses, upholstery, above-floor surfaces, vehicle interiors or others.
- the cleaning device 1 has a base device 14 and an accessory 13 that is detachably connected to the base device 14.
- the accessory 13 here is, for example, a suction nozzle with a floor processing element 12 that can be rotated about a substantially horizontal axis.
- the cleaning device 1 can also be connected to other types of accessories 13, for example with a wiping accessory, an upholstery brush, narrow suction nozzles for interior cleaning vehicles or others.
- a fan, a fan motor and a dust chamber are arranged in the base device 14 - not shown here.
- the base device 14 furthermore has - facing away from the accessories 13 - a handle 16 with a handle 17, by means of which a user can guide the cleaning device 1 in a usual back and forth movement over a surface to be cleaned.
- the handle 16 is advantageously designed to be telescopic, so that the user can adjust its length to his body size in order to handle the cleaning device 1 comfortably.
- the handle 17 has an operating device 18 with, for example, a plurality of actuating elements (not shown in detail), which can be designed, for example, as push buttons.
- the operating device 18 can also have other types of actuating elements, for example slide switches, rotary switches, toggle switches or even a touchscreen.
- the user can, for example, set a fan speed of the blower or a speed of the soil cultivation element 12 in order to work an area in the best possible way.
- the operating device 18 thus serves as a communication interface 2, via which the user can communicate directly with a control and evaluation device 10 of the cleaning device 1, namely, for example, can transmit specifications to it.
- the external terminal 4 is designed here, for example, as a mobile phone.
- the external terminal 4 can also be another, preferably mobile, external terminal 4.
- it can be provided to use a tablet computer, a laptop or similar as the terminal device 4.
- the external terminal 4 preferably has a display 11 in the usual manner, which is particularly preferably designed as a touchscreen. The user can then receive information as well as make inputs via this display 11, so that the display 11 simultaneously serves as a communication interface 3 of the external terminal 4.
- the external terminal 4 is in communication connection with the cleaning device 1.
- the cleaning device 1 and the external terminal 4 have communication modules (not shown), for example WLAN modules, Bluetooth modules or others.
- the communication modules of the cleaning device 1 and the external terminal 4 can be integrated into the user's home network.
- direct communication can also take place, particularly based on Bluetooth or Zigbee.
- An application is also installed on the external terminal 4 and the cleaning device 1 to implement the method according to the invention to carry out.
- a server (not shown) can also be integrated into the communication network, which can contain, for example, information about cleaning activities 5 of the cleaning device 1, for example information about steps 9, which are to be carried out as part of a cleaning activity 5.
- Device parameters that the cleaning device 1 has to have at the time of executing the respective step 9 can also be stored associated with these steps 9.
- the data can be stored centrally in the server and thus accessed by other devices in the home network, in particular the cleaning device 1 and the external terminal 4.
- the data is at least stored in a local memory of the cleaning device 1.
- the memory of the cleaning device 1 has information about a plurality of stored cleaning activities 5 that the cleaning device 1 can carry out. For each cleaning activity 5, at least one device setting 6 and/or at least one device application 7 is stored, which the user has to carry out himself.
- the memory of the cleaning device 1 or the central server also has instructions 8 for carrying out the cleaning activity 5.
- This instruction 8 can be displayed to the user on the communication interface 2 of the cleaning device 1 and/or the communication interface 3 of the external terminal 4.
- the instructions 8 can be in text form and/or image form and/or video form and/or audio form and contain a plurality of steps 9 that are to be carried out sequentially by the user. This will be discussed later with reference to the Figures 3 to 6 executed.
- the cleaning device 1 further has one or preferably several detection devices (not shown in detail), which can measure a device parameter of the cleaning device 1.
- a device parameter can, for example, be a voltage, current, speed, frequency, temperature, liquid flow, fill level, energy consumption of an electrical consumer or similar.
- the device parameters are those which are caused by a device setting 6 and/or a device application 7 by the user, for example by a device setting 6, such as a power of a drive motor for the soil processing element 12 or for selected by the user via the operating device 18 of the cleaning device 1 a suction fan of the cleaning device 1.
- the detection device can also detect a device parameter caused by a device application 7, for example that the user has connected the cleaning device 1 to a specific accessory 13.
- the detection device can, for example, have a code scanner, which can read a code of an accessory 13 that is correctly connected to the base device 14.
- a device application 7 can, for example, also be a movement of the cleaning device 1 over a surface to be cleaned, the movement being detected by means of a motion sensor or similar.
- cleaning activities 5 are according to Figure 2
- upholstery cleaning, mattress cleaning, carpet cleaning and hard floor cleaning can be selected.
- other cleaning activities 5 can also be selected, in particular in conjunction with suitable accessories 13.
- Cleaning activities 5 also include vehicle interior cleaning, floor cleaning, stain removal, wet cleaning, damp cleaning, dry cleaning or cleaning using cleaning agents . Combinations of these cleaning activities 5 can also be provided, for example wet carpet cleaning, stain removal using cleaning agent or others.
- the user chooses here now, for example, the cleaning activity 5 "cushion", whereupon the external terminal 4 transmits information about the cleaning activity 5 to be carried out to the control and evaluation device 10 of the cleaning device 1.
- the user can start a guide 8, which guides him step by step through the device settings 6 and/or device applications 7 to be made, which serve to optimally carry out the selected cleaning activity 5.
- the instructions 8 contain a plurality of steps 9, which are shown here, for example Figures 3 to 5 are shown in more detail.
- the instructions 8 can, for example, be stored in a local memory of the cleaning device 1 or on a server with which the external terminal 4 and/or the cleaning device 1 is in communication connection.
- the instructions 8 can be stored locally in the external terminal 4.
- a computing device of the external terminal 4 retrieves the instructions 8 belonging to the cleaning activity 5 "upholstery" from a web server which is in communication connection with the external terminal 4.
- the user is then informed, as in Figure 3 shown, a first step 9 "Step 1" is displayed, which is to be carried out by the user on the cleaning device 1.
- “Step 1” involves the user connecting an upholstery brush as an accessory 13 to the base device 14 of the cleaning device 1.
- this is a device application 7 that is to be executed by the user. While this step 9 is displayed on the display 11 of the external terminal 4, a detection device of the cleaning device 1 detects whether the user actually carries out step 9.
- the cleaning device 1 has, for example, a contact sensor and/or code scanner as a detection device.
- the contact sensor can detect contact between an accessory 13 and the base device 14.
- the code scanner can also determine whether the connected accessory 13 is also the expected “upholstery brush” accessory.
- the base device 14 of the cleaning device 1 can preferably be connected to different accessories 13 to carry out different cleaning activities 5.
- Each accessory 13 accordingly has a code which uniquely identifies the accessory 13.
- the detection signal from the detection device can then either be evaluated by the cleaning device 1's own control and evaluation device 10 or forwarded unprocessed to the external terminal 4. In the latter case, the computing device of the external terminal 4 takes over the evaluation of the detection signal from the detection device.
- the control and evaluation device 10 of the cleaning device 1 or the computing device of the external terminal 4 accesses a memory device in which a reference amount characteristic of the device application 7 "connect upholstery brush" is stored.
- This reference amount can be, for example, the code of the accessory 13 “upholstery brush”. If the detection device then reads a code that corresponds to the stored reference amount, step 9 of instructions 8 is considered to have been carried out correctly.
- the instructions 8 then proceed to a next step 9.
- This next “Step 2" is in Figure 4 and includes the request "Select fan level 1".
- the user of the cleaning device 1 is thus requested to make a device setting 6 on the cleaning device 1.
- the device setting 6 can be made here, for example, using the operating device 18 of the base device 14.
- the operating device 18 can, for example, have three operating elements for 3 different fan levels, which are named “fan level 1", “fan level 2" and “fan level 3”.
- the user then operates the control element of the control device 18 which corresponds to “blower level 1”.
- a detection device of the cleaning device 1 can then, for example, detect the device parameter “power of the blower motor” and compare it with a reference amount or reference range defined for “Step 2”. If the values match, the user has correctly executed the specified device setting 6 and the one on the external Instructions 8 displayed on the terminal 4 proceed to the next step 9, namely “Step 3”.
- the next step 3 of instructions 8 includes - as in Figure 5 shown - that the user moves the cleaning device 1 over the surface to be cleaned, namely in a sequence of back and forth movements.
- the display 11 of the external terminal 4 thus shows the user that he has to execute the device application 7 "move the device back and forth on the surface".
- the device application 7 of the “back and forth movement” is characterized, for example, by an acceleration, speed and/or change in location of the cleaning device 1 in the environment, which can be detected by a corresponding detection device.
- the control and evaluation device 10 then accesses the associated memory device in which a reference amount or reference range for this device parameter is stored, for example an acceleration amount or speed.
- a reference range can be defined that contains a large number of reference amounts that are still considered to be in accordance with the specifications. If the control and evaluation device 10 then determines that the measured amount of the device parameter, ie the measured amount of acceleration or speed, lies within this reference range, step 9 "move the device back and forth on the surface" is considered to have been carried out correctly. Instructions 8 have now been completed and the cleaning activity has ended. The user can receive a message about this.
- Figure 6 shows an alternative course when carrying out the cleaning activity 5.
- the user has made a device setting 6 here that is not the one required in step 9
- Device setting 6 according to instructions 8 corresponds.
- the user has selected “fan level 2” instead of “fan level 1”.
- the control and evaluation device 10 of the cleaning device 1 accordingly recognizes that the device parameter does not correspond to the reference amount or reference range defined for the device setting 6 "Select fan level 1".
- the device parameter here is, for example, the power of the blower motor.
- other device parameters can also be measured for checking, for example a speed of a motor shaft of the electric motor driving the fan.
- the control and evaluation device 10 therefore recognizes the deviation and transmits the in Figure 6 shown note 15 "Application stopped, select fan level 1" to the user. Furthermore, for example, the fan of the cleaning device 1 can also be stopped completely until the user sets the device setting 6 as specified.
- the instructions 8 for the cleaning activity 5 do not proceed to a subsequent step 9 if the user has not made the device setting 6 as intended.
- the instructions 8 themselves can be structured modularly in such a way that a subsequently displayed step 9 is influenced by the execution of the step 9 to be carried out beforehand.
- a decision is made based on the specific situation as to which subsequent step 9 will be presented to the user.
- the instructions 8 are kept in a step 9 until the evaluation of the measured device parameters shows that the prerequisites for the progression of the instructions 8 are met. The user is therefore within the current step 9 as long as possible for a required corrective action, ie always Device setting 6 that still needs to be carried out is indicated until this has been carried out correctly.

Daneben betrifft die Erfindung ein Reinigungsgerät mit einer Kommunikationsschnittstelle, welches zur Ausführung eines solchen Verfahrens ausgebildet ist.In addition, the invention relates to a cleaning device with a communication interface, which is designed to carry out such a method.
Verfahren und Reinigungsgeräte der vorgenannten Art sind im Stand der Technik bekannt. Diese sind üblicherweise manuell von einem Nutzer handgeführte Reinigungsgeräte, welche vorzugsweise zur Ausführung einer Mehrzahl unterschiedlicher Reinigungstätigkeiten ausgebildet sind. Zu den Reinigungstätigkeiten zählen beispielsweise eine Hartbodenreinigung, eine Teppichbodenreinigung, eine Überbodenreinigung, eine Feuchtreinigung und dergleichen.Methods and cleaning devices of the aforementioned type are known in the prior art. These are usually cleaning devices that are manually operated by a user and are preferably designed to carry out a number of different cleaning activities. The cleaning activities include, for example, hard floor cleaning, carpet cleaning, above-floor cleaning, wet cleaning and the like.
Neben den manuell geführten Reinigungsgeräten sind im Stand der Technik auch im Wesentlichen autonom arbeitende Reinigungsroboter bekannt, die beispielsweise in unterschiedlichen Betriebsmodi betrieben werden können.In addition to the manually operated cleaning devices, essentially autonomous cleaning robots are also known in the prior art, which can be operated in different operating modes, for example.
Üblicherweise wählt der Nutzer eine von mehreren Reinigungstätigkeiten, die mit dem Reinigungsgerät ausführbar sind, und führt dann bestimmte Geräteeinstellungen und/oder Geräteanwendungen durch. Zu den Geräteeinstellungen gehören beispielsweise die Einstellung einer Leistungsstufe eines Gebläses oder einer Drehzahl einer rotierenden Reinigungsbürste. Eine von dem Nutzer ausgeführte Geräteanwendung kann beispielsweise eine bestimmte Bewegungsgeschwindigkeit des Reinigungsgerätes über die zu reinigende Fläche oder auch das Verbinden des Reinigungsgerätes mit einem bestimmten Zubehör sein. Bei dem Zubehör handelt es sich beispielsweise um eine lösbar mit einem Basisgerät des Reinigungsgerätes verbindbare Saugdüse, einen Wischaufsatz oder ähnliches.Typically, the user selects one of several cleaning activities that can be carried out with the cleaning device and then carries out certain device settings and/or device applications. The device settings include, for example, setting a power level of a blower or a speed of a rotating cleaning brush. A device application carried out by the user can, for example, be a certain speed of movement of the cleaning device over the surface to be cleaned or the connection of the cleaning device to a certain accessory. The accessories are, for example, a suction nozzle that can be detachably connected to a base device of the cleaning device, a mop attachment or similar.
Üblicherweise wählt der Nutzer die Geräteeinstellungen und/oder Geräteanwendungen nach seinem eigenen Belieben oder seiner eigenen Einschätzung. Sofern er hierzu eine Hilfestellung benötigt, kann er auf ein Handbuch des Reinigungsgerätes zugreifen oder auch in einem Internetforum, welches eine Mehrzahl von Nutzern gleichartiger Reinigungsgeräte verbindet, nach Hilfe suchen.Typically, the user selects the device settings and/or device applications according to his or her own preference or judgment. If he needs help with this, he can access a manual for the cleaning device or look for help in an Internet forum that connects a number of users of similar cleaning devices.
Nachteilig bei den vorgenannten Verfahren ist, dass der Nutzer unter Umständen Fehlanwendungen des Reinigungsgerätes oder zumindest für eine Reinigungstätigkeit ungünstige Geräteeinstellungen vornimmt und daher kein optimales Reinigungsergebnis erzielen kann. Ein Verfahren zum Betrieb eines Reinigungsgerätes gemäß dem Oberbegriff des Anspruchs 1 ist z.B. aus
Ausgehend von dem vorgenannten Stand der Technik ist es daher Aufgabe der Erfindung, ein Verfahren zum Betrieb eines Reinigungsgerätes derart weiterzubilden, dass der Nutzer des Reinigungsgerätes mit geringem Aufwand eine Reinigungstätigkeit mit optimalem Reinigungsergebnis ausführen kann.Based on the aforementioned prior art, it is therefore the object of the invention to develop a method for operating a cleaning device in such a way that the user of the cleaning device can carry out a cleaning activity with optimal cleaning results with little effort.
Zur Lösung der vorgenannten Aufgabe wird vorgeschlagen, dass dem Nutzer in Abhängigkeit von der ausgewählten Reinigungstätigkeit über die Kommunikationsschnittstelle eine Anleitung für eine Mehrzahl von zeitlich aufeinanderfolgend von dem Nutzer auszuführenden Schritten, welche eine Geräteeinstellung und/ oder Geräteanwendung beinhalten, übermittelt wird, und wobei eine Steuer- und Auswerteeinrichtung des Reinigungsgerätes oder des externen Endgerätes korrespondierend zu dem aktuell auszuführenden Schritt die tatsächliche Ausführung der Geräteeinstellung und/oder Geräteanwendung überwacht und in dem Fall, dass die von dem Nutzer tatsächlich ausgeführte Geräteeinstellung und/oder Geräteanwendung von einer vordefinierten Referenz für die auszuführende Geräteeinstellung und/ oder Geräteanwendung abweicht, einen Hinweis an den Nutzer übermittelt.To solve the aforementioned problem, it is proposed that, depending on the selected cleaning activity, the user is provided with instructions for a plurality of steps to be carried out sequentially by the user via the communication interface, which include a device setting and/or device application, and wherein a tax - and evaluation device of the cleaning device or the external terminal corresponding to the step currently to be carried out monitors the actual execution of the device setting and / or device application and in the case that the device setting and / or device application actually carried out by the user is based on a predefined reference for the device setting to be carried out and/or device application differs, a notice is sent to the user.
Erfindungsgemäß muss der Nutzer nun nicht mehr selbst in Handbüchern oder Foren nach Hilfestellungen für eine auszuführende Reinigungstätigkeit suchen, sondern bekommt diese unmittelbar von dem Reinigungsgerät selbst beziehungsweise von einem mit dem Reinigungsgerät in Kommunikationsverbindung stehenden externen Endgerät übermittelt. Zu diesem Zweck übermittelt das Reinigungsgerät beziehungsweise das externe Endgerät eine Anleitung zur Durchführung der Reinigungstätigkeit an den Nutzer. Die Anleitung enthält eine Mehrzahl von auszuführenden Schritten, welche der Nutzer auszuführen hat. Im Wesentlichen entspricht die Anleitung einer schrittweisen Beschreibung der von dem Nutzer auszuführenden Vorgehensweise bei der Durchführung der gewählten Reinigungstätigkeit. Die Ausgabe der einzelnen Schritte der Anleitung kann dabei wie vorgeschlagen nicht nur über die Kommunikationsschnittstelle des Reinigungsgerätes selbst erfolgen, sondern alternativ auch auf einem externen Endgerät, beispielsweise einem Mobilgerät, insbesondere Mobiltelefon oder Tablet-Computer oder auch auf einem externen stationären Gerät, wie beispielsweise einem TV-Gerät oder ähnlichem. Die Anleitung kann dem Nutzer Hinweise zum weiteren Vorgehen in Textform, als Bild, Video und/oder Sprachausgabe geben. Insbesondere können die derart mitgeteilten Schritte der Anleitung auch Durchführungsbeispiele für die jeweilige Reinigungstätigkeit liefern. Die Anleitung selbst kann in einem lokalen Speicher des Reinigungsgerätes, einem lokalen Speicher des externen Endgerätes oder auch einem Web-Server hinterlegt sein, beispielweise auf einem Server des Herstellers des Reinigungsgerätes. Die Kommunikation zwischen dem Reinigungsgerät und einem externen Endgerät und/ oder einem Web-Server erfolgt vorzugsweise mittels kabelloser Datenkommunikation, beispielsweise im Rahmen eines WLAN-Netzwerkes, per Bluetooth oder durch andere drahtlose Kommunikationstechnologien.According to the invention, the user no longer has to search for help in manuals or forums for a cleaning activity to be carried out, but receives this directly from the cleaning device itself or from an external terminal that is in communication with the cleaning device. For this purpose, the cleaning device or the external terminal transmits instructions on how to carry out the cleaning activity to the user. The instructions contain a number of steps that the user must carry out. Essentially, the instructions correspond to a step-by-step description of the procedure to be carried out by the user Carrying out the selected cleaning activity. As suggested, the individual steps of the instructions can be output not only via the communication interface of the cleaning device itself, but alternatively also on an external device, for example a mobile device, in particular a mobile phone or tablet computer, or also on an external stationary device, such as a TV or similar. The instructions can provide the user with information on how to proceed in text form, as an image, video and/or voice output. In particular, the steps of the instructions communicated in this way can also provide implementation examples for the respective cleaning activity. The instructions themselves can be stored in a local memory of the cleaning device, a local memory of the external device or even a web server, for example on a server of the manufacturer of the cleaning device. The communication between the cleaning device and an external device and/or a web server preferably takes place via wireless data communication, for example within the framework of a WLAN network, via Bluetooth or via other wireless communication technologies.
Nach Erhalt der Anleitung zum Ausführen der Reinigungstätigkeit beziehungsweise nach Erhalt eines ersten Schrittes zum Ausführen der Reinigungstätigkeit führt der Nutzer den ersten Schritt aus. Dies beinhaltet, dass der Nutzer eine bestimmte Einstellung und/oder Geräteanwendung an dem Reinigungsgerät ausführt. Beispielsweise hat der Nutzer als Geräteeinstellung eine bestimmte Leistungsstufe eines Gebläses des Reinigungsgerätes einzustellen. Zu weiteren möglichen Geräteeinstellungen wird später noch umfassender ausgeführt. Des Weiteren kann der Schritt auch alternativ oder zusätzlich beinhalten, dass der Nutzer eine bestimmte Geräteanwendung auszuführen hat. Beispielsweise ist das Reinigungsgerät über die zu reinigende Fläche zu führen, insbesondere in einer Abfolge von Hin- und Herbewegungen und/oder mit einer bestimmten Geschwindigkeit. Eine Geräteanwendung kann des Weiteren auch beinhalten, dass der Nutzer ein bestimmtes Zubehör mit dem Reinigungsgerät verbindet, beispielsweise eine Saugdüse, welche eine rotierende Reinigungsbürste beinhaltet.After receiving the instructions for carrying out the cleaning activity or after receiving a first step for carrying out the cleaning activity, the user carries out the first step. This involves the user carrying out a specific setting and/or device application on the cleaning device. For example, the user has to set a specific power level of a fan of the cleaning device as a device setting. Further possible device settings will be explained in more detail later. Furthermore, the step can alternatively or additionally include that the user has to execute a specific device application. For example, the cleaning device must be guided over the surface to be cleaned, in particular in a sequence of back and forth movements and/or at a certain speed. A device application can further also involve the user connecting a certain accessory to the cleaning device, for example a suction nozzle that contains a rotating cleaning brush.
Das Reinigungsgerät weist eine geräteinterne Kommunikationstechnologie auf, durch welche die Steuer- und Auswerteeinrichtung des Reinigungsgerätes Kenntnis darüber erlangt, welche Einstellungen beziehungsweise Anwendungen der Nutzer vorgenommen hat. Hierzu weist das Reinigungsgerät beispielsweise eine Mehrzahl von Detektionseinrichtungen auf, wie beispielsweise einen Kontaktsensor, welcher das Anschließen eines Zubehörs an das Reinigungsgerät erkennt, einen Leistungsmesser zum Detektieren einer Leistungsaufnahme eines elektrischen Verbrauchers, einen Beschleunigungssensor, welcher ein Hin- und Herbewegen des Reinigungsgerätes über eine zu reinigende Fläche detektieren kann oder ähnliches. Die Steuer- und Auswerteeinrichtung des Reinigungsgerätes kann die Messwerte auswerten und diese mit einer vordefinierten Referenz vergleichen, welche für den betreffenden Schritt der ausgewählten Reinigungstätigkeit festgelegt ist.The cleaning device has device-internal communication technology through which the control and evaluation device of the cleaning device gains knowledge of which settings or applications the user has made. For this purpose, the cleaning device has, for example, a plurality of detection devices, such as a contact sensor, which detects the connection of an accessory to the cleaning device, a power meter for detecting a power consumption of an electrical consumer, an acceleration sensor, which detects the back and forth movement of the cleaning device over a can detect cleaning surface or something similar. The control and evaluation device of the cleaning device can evaluate the measured values and compare them with a predefined reference, which is defined for the relevant step of the selected cleaning activity.
Es empfiehlt sich, dass dem Nutzer die Anleitung zum Ausführen der Reinigungstätigkeit beziehungsweise der erste Schritt der Anleitung dann übermittelt wird, wenn der Nutzer die Reinigungstätigkeit ausgewählt hat. Zum Auswählen der Reinigungstätigkeit wählt der Nutzer beispielsweise auf einem Display, insbesondere einem Touchscreen, des Reinigungsgerätes oder eines externen Endgerätes eine von mehreren angezeigten Reinigungstätigkeiten aus und drückt dann einen Startbutton. Daraufhin erhält er durch einen ersten auszuführenden Schritt der Anleitung eine Anweisung dahingehend, welche Geräteeinstellung beziehungsweise Geräteanwendung er vorzunehmen hat. Alternativ kann der Nutzer die Anleitung auch separat starten, d.h. unabhängig von dem Zeitpunkt, zu welchem er die Reinigungstätigkeit auswählt, beispielsweise in dem Moment, in welchem er die Reinigungstätigkeit tatsächlich ausführen möchte. Wenn der Nutzer eine vorgegebene Geräteeinstellung und/oder Geräteanwendung ausgeführt hat, wird überprüft, ob der Nutzer den vorgegebenen Schritt anleitungsgemäß ausgeführt hat. Sofern dies der Fall ist, bekommt der Nutzer den nächsten Schritt der Anleitung übermittelt. Somit existieren im Wesentlichen zwei verschiedene Reaktionen auf die Einstellung beziehungsweise Anwendung des Nutzers, nämlich zum einen ein Fortschreiten der Präsentation, falls ermittelt wird, dass der Nutzer den Schritt korrekt ausgeführt hat, d.h. die Geräteeinstellung beziehungsweise Geräteanwendung mit der vordefinierten Referenz übereinstimmt, und zum anderen ein Stoppen der Präsentation, wenn die Handlung des Nutzers von der vordefinierten Referenz für diesen Anleitungsschritt abweicht. In dem letztgenannten Fall kann die Steuer- und Auswerteeinrichtung einen Hinweis auf die festgestellte Abweichung ausgeben und den Nutzer um Korrektur bitten. Wie die Anleitung, kann der Nutzer auch den Hinweis über eine Abweichung von der Anleitung auf dem Display des Reinigungsgerätes oder dem Display des externen Endgerätes angezeigt bekommen. Insgesamt wird der Nutzer somit schrittweise durch die aufeinanderfolgenden Schritte der Reinigungstätigkeit geführt. Dabei wird kontrolliert, ob die Durchführung des Nutzers vorschriftsgemäß erfolgte.It is recommended that the instructions for carrying out the cleaning activity or the first step of the instructions are sent to the user when the user has selected the cleaning activity. To select the cleaning activity, the user selects, for example, one of several cleaning activities displayed on a display, in particular a touchscreen, of the cleaning device or an external terminal and then presses a start button. He then receives instructions as to which device setting or device application he has to carry out in a first step of the instructions. Alternatively, the user can also start the instructions separately, that is, regardless of the time at which they select the cleaning activity, for example at the moment when he actually wants to carry out the cleaning activity. If the user has carried out a specified device setting and/or device application, it is checked whether the user has carried out the specified step according to the instructions. If this is the case, the user will be sent the next step in the instructions. There are therefore essentially two different reactions to the user's setting or application, namely, on the one hand, a progression of the presentation if it is determined that the user has carried out the step correctly, ie the device setting or device application matches the predefined reference, and on the other hand stopping the presentation if the user's action deviates from the predefined reference for this instruction step. In the latter case, the control and evaluation device can issue a note about the detected deviation and ask the user to correct it. Like the instructions, the user can also see a notice about a deviation from the instructions on the display of the cleaning device or the display of the external device. Overall, the user is guided step by step through the successive steps of the cleaning activity. This checks whether the user's implementation was carried out in accordance with the regulations.
Es wird des Weiteren vorgeschlagen, dass eine Detektionseinrichtung des Reinigungsgerätes einen aktuellen Betrag eines für die Geräteeinstellung und/oder Geräteanwendung charakteristischen Geräteparameters des Reinigungsgerätes misst und an die Steuer- und Auswerteeinrichtung kommuniziert. Beim Ausführen einer Geräteeinstellung beziehungsweise einer Geräteanwendung wird an dem Reinigungsgerät ein charakteristischer Geräteparameter eingestellt, welcher von der Detektionseinrichtung des Reinigungsgerätes gemessen werden kann und dessen Betrag mit einem entsprechenden Referenzbetrag beziehungsweise Referenzbereich verglichen wird. Bei den detektierbaren Geräteparametern handelt es sich um messbare physikalische Parameter, wie beispielsweise Spannung, Stromstärke, Drehzahl, Frequenz, Geschwindigkeit, Beschleunigung, Kraft oder ähnliche. Auch kann zwischen den Werten "Null" und "Eins" unterschieden werden, beispielsweise bezogen auf einen Kontakt mit einem Zubehör, wobei "Null" keinen Kontakt zu einem Zubehör anzeigt und "Eins" einen Kontakt mit einem Zubehör anzeigt. Darüber hinaus kann eine Detektionseinrichtung des Reinigungsgerätes beispielsweise auch einen Code eines Zubehörs auslesen und somit erkennen, welches Zubehör aus einer Mehrzahl von zur Verfügung stehendem Zubehör mit dem Reinigungsgerät verbunden wurde.It is further proposed that a detection device of the cleaning device measures a current amount of a device parameter of the cleaning device that is characteristic of the device setting and/or device application and communicates it to the control and evaluation device. When executing a device setting or a device application, a characteristic device parameter is set on the cleaning device, which can be measured by the detection device of the cleaning device and whose amount is compared with a corresponding reference amount or reference range. The detectable device parameters are measurable physical parameters, such as voltage, current, speed, frequency, speed, acceleration, force or similar. A distinction can also be made between the values "zero" and "one", for example based on contact with an accessory, where "zero" indicates no contact with an accessory and "one" indicates contact with an accessory. In addition, a detection device of the cleaning device can, for example, also read out a code of an accessory and thus recognize which accessory from a plurality of available accessories has been connected to the cleaning device.
In diesem Zusammenhang kann insbesondere vorgesehen sein, dass die Steuer- und Auswerteeinrichtung auf eine Speichereinrichtung zugreift, in welcher ein für die Geräteeinstellung und/oder Geräteanwendung definierter Referenzbetrag oder Referenzbereich des Geräteparameters gespeichert ist, wobei die Steuer- und Auswerteeinrichtung den gemessenen Betrag des Geräteparameters mit dem gespeicherten Referenzbetrag oder Referenzbereich vergleicht. In dem Fall, dass für den Vergleich ein Referenzbereich für den Geräteparameter vorgegeben ist, kann der gemessene Geräteparameter eine bestimmte Betragsspanne einnehmen. Somit ist es nicht erforderlich, dass ein gemessener Geräteparameter absolut identisch zu einem einzigen Referenzbetrag ist. Vielmehr wird damit eine gewisse Toleranz miteinbezogen, die bei der Entscheidung darüber berücksichtigt wird, ob der Nutzer eine Geräteeinstellung und/ oder Geräteanwendung vorschriftsgemäß vorgenommen hat.In this context, it can be provided in particular that the control and evaluation device accesses a memory device in which a reference amount or reference range of the device parameter defined for the device setting and/or device application is stored, with the control and evaluation device including the measured amount of the device parameter compares with the stored reference amount or reference range. In the event that a reference range is specified for the device parameter for the comparison, the measured device parameter can have a certain amount range. It is therefore not necessary for a measured device parameter to be absolutely identical to a single reference amount. Rather, a certain tolerance is included, which is taken into account when deciding whether the user has made a device setting and/or device application in accordance with the regulations.
Es wird des Weiteren vorgeschlagen, dass die zeitlich aufeinanderfolgend auszuführenden Schritte dem Nutzer zeitlich separat mitgeteilt werden, sodass der Nutzer nur die Geräteeinstellung und/oder Geräteanwendung des nächsten auszuführenden Schrittes der Anleitung mitgeteilt bekommt. Durch diese Ausgestaltung wird verhindert, dass der Nutzer Anleitungsschritte überspringt oder fehlerhaft miteinander kombiniert. Der Nutzer kann sich gemäß der vorgeschlagenen Verfahrensweise auf die nächste auszuführende Geräteeinstellung beziehungsweise durchzuführende Geräteanwendung konzentrieren. Zudem kann darauf aufbauend erreicht werden, dass dem Nutzer ein zeitlich später auszuführender Schritt der Anleitung erst dann mitgeteilt wird, wenn die von dem Nutzer ausgeführte Geräteeinstellung und/oder Geräteanwendung des zeitlich vorausgehenden Schrittes mit der vordefinierten Referenz für diesen zeitlich vorausgehenden Schritt übereinstimmt. Gemäß dieser Ausgestaltung kann nämlich erkannt werden, zu welchem Zeitpunkt der Nutzer einen Anwendungsfehler gemacht hat. Daraufhin wird das Reinigungsgerät dann in demjenigen Status gehalten, welcher der fehlerhaften Geräteeinstellung beziehungsweise Geräteanwendung entspricht. Eine Fehlanwendung oder nicht optimale Einstellung des Reinigungsgerätes kann somit bestmöglich und zum frühestmöglichen Zeitpunkt bereinigt werden. Der Betrieb des Reinigungsgerätes beziehungsweise zumindest die Ausführung der gewählten Reinigungstätigkeit wird angehalten und der Nutzer erhält über einen übermittelten Hinweis eine Nachricht darüber, wie er weiter verfahren kann, um die Reinigungstätigkeit doch noch zu einem Erfolg zu führen.It is further proposed that the steps to be carried out in succession are communicated to the user separately, so that the user is only informed of the device setting and/or device application of the next step of the instructions to be carried out. This design prevents the user from skipping instruction steps or incorrectly combined with each other. According to the proposed procedure, the user can concentrate on the next device setting to be carried out or device application to be carried out. In addition, based on this, it can be achieved that the user is only informed of a step in the instructions to be carried out later when the device setting and/or device application of the previous step carried out by the user matches the predefined reference for this previous step. According to this embodiment, it can be recognized at which point in time the user made an application error. The cleaning device is then kept in the status that corresponds to the incorrect device setting or device application. Incorrect use or non-optimal settings of the cleaning device can therefore be cleaned up in the best possible way and at the earliest possible time. The operation of the cleaning device or at least the execution of the selected cleaning activity is stopped and the user receives a message via a message about how he can proceed in order to make the cleaning activity a success.
Bevorzugt kann der Nutzer an dem Reinigungsgerät beziehungsweise dem externen Endgerät eine Auswahl einer Reinigungstätigkeit aus einer Vielzahl verschiedener zur Verfügung stehender Reinigungstätigkeiten vornehmen. Bevorzugt ist auf dem Reinigungsgerät und/oder dem externen Endgerät eine Applikation installiert, welche dem Nutzer verschiedene Alternativen für auszuführende Reinigungstätigkeiten anbietet. Die Reinigungstätigkeit kann insbesondere eine Polsterreinigung und/oder Matratzenreinigung und/oder Teppichreinigung und/oder Fahrzeuginnenreinigung und/oder Überbodenreinigung und/ oder Fleckentfernung und/ oder Naßreinigung und/ oder Feuchtreinigung und/oder Trockenreinigung und/oder Teppichbodenreinigung und/oder Hartbodenreinigung und/oder eine Reinigung mit Auftrag von Reinigungsmittel sein. Die Ausführung der Reinigungstätigkeit beinhaltet beispielsweise auch eine Vielzahl aufeinanderfolgender Tätigkeitsschritte, welche der Nutzer jeweils einzeln im Rahmen eines separaten Schrittes der Anleitung auszuführen hat. Beispielsweise kann die Reinigungstätigkeit "Polsterreinigung" zunächst einen ersten Schritt erfordern, welcher das Verbinden des Reinigungsgerätes mit einem definierten Zubehör beinhaltet. Ein nachfolgender Arbeitsschritt kann beispielsweise das Auftragen von Polsterreinigungsmittel auf die zu reinigende Fläche sein. Ein wiederum darauf folgender Arbeitsschritt kann dann eine Klopfbearbeitung der zu reinigenden Fläche umfassen. Wenn der Nutzer den ersten Arbeitsschritt bereits nicht korrekt ausgeführt hat, beispielsweise ein falsches Zubehör mit dem Reinigungsgerät verbunden hat, schreitet die Anleitung nicht fort. Vielmehr wird der Nutzer darüber informiert, dass ein Fehler vorliegt und wie dieser beseitigt werden kann. Erst nachdem der Nutzer ein korrektes Zubehör angeschlossen hat, schreitet die Anleitung zu dem nächsten Arbeitsschritt fort, nämlich dem Auftragen von Polsterreinigungsmittel.The user can preferably select a cleaning activity from a large number of different cleaning activities available on the cleaning device or the external terminal. An application is preferably installed on the cleaning device and/or the external terminal, which offers the user various alternatives for cleaning activities to be carried out. The cleaning activity can in particular be upholstery cleaning and/or mattress cleaning and/or carpet cleaning and/or vehicle interior cleaning and/or floor cleaning and/or stain removal and/or wet cleaning and/or wet cleaning and/or dry cleaning and/or carpet cleaning and/or hard floor cleaning and/or a Cleaning with the application of cleaning agents be. The execution of the cleaning activity also includes, for example, a large number of successive activity steps, which the user has to carry out individually as part of a separate step in the instructions. For example, the cleaning activity “upholstery cleaning” may initially require a first step that involves connecting the cleaning device to a defined accessory. A subsequent step can be, for example, applying upholstery cleaning agent to the surface to be cleaned. A subsequent work step can then include tapping the surface to be cleaned. If the user has not already carried out the first step correctly, for example connecting the wrong accessory to the cleaning device, the instructions will not progress. Rather, the user is informed that there is an error and how it can be eliminated. Only after the user has connected the correct accessories do the instructions move on to the next step, namely applying upholstery cleaning agent.
Im Verlauf der Arbeitsschritte der Anleitung wird der Nutzer aufgefordert, eine oder mehrere Geräteeinstellungen und/oder eine oder mehrere Geräteanwendungen durchzuführen. Zu den Geräteeinstellungen gehören, dies aber nicht abschließend, eine Leistung eines elektrischen Verbrauchers des Reinigungsgerätes, eine Abgabemenge einer Flüssigkeits-Auftragseinrichtung und/oder Reinigungsmittel-Auftragseinrichtung, eine Drehzahl oder Schwingungsfrequenz eines eine Fläche bearbeitenden Bodenbearbeitungselementes, eine Stellung eines Dichtelementes eines Strömungskanals, ein Strömungsquerschnitt eines Strömungskanals, und andere. Zu den Geräteanwendungen gehören, dies ebenfalls nicht abschließend, ein Verbinden des Reinigungsgerätes mit einem Zubehör, insbesondere einer Saugdüse und/oder Reinigungsbürste und/oder einem Wischelement, ein Auftragen einer Flüssigkeit auf eine zu reinigende Fläche, ein Bewegen des Reinigungsgerätes über die zu reinigende Fläche, ein Ausführen der Reinigungstätigkeit über eine bestimmte Zeitspanne oder andere. Ein Schritt der Anleitung kann auch eine Kombination aus einer oder mehreren Geräteeinstellungen und einer oder mehreren Geräteanwendungen beinhalten, beispielsweise den Betrieb eines Gebläses in einer bestimmten Leistungsstufe, ein Anschließen eines bestimmten Zubehörs an ein Basisgerät und ein Hin- und Herbewegen des Reinigungsgerätes über die zu reinigende Fläche. Die Anleitung mit den zeitlich aufeinanderfolgenden Schritten kann modular strukturiert sein. Dies bedeutet, dass jeder Schritt, der eine Interaktion des Nutzers mit dem Reinigungsgerät beziehungsweise einem Zubehör vorsieht, eine Mehrzahl alternativer Folgeschritte nach sich ziehen kann, wobei der Folgeschritt davon abhängt, wie der Nutzer den vorausgehenden Schritt durchgeführt hat. Dies bedeutet, dass der als nächstes angezeigte Schritt der Anwendung von dem Auswerteergebnis der Steuer- und Auswerteeinrichtung abhängt, nämlich davon, ob die gemessenen Geräteparameter mit einer vordefinierten Referenz übereinstimmen. Vor jedem Fortgang der Anleitung wird somit entschieden, welcher der alternativen Folgeschritte dem Nutzer präsentiert wird. Dies kann insbesondere relevant sein, wenn die Geräteparameter einen bestimmten Parameterbereich einnehmen können. So kann es zum Beispiel bei einem Messwert in einem oberen Bereich des Referenzbereiches zu einem anderen Folgeschritt kommen als im Falle eines Geräteparameters in einem unteren Bereich des Referenzbereiches. Des Weiteren kann beispielsweise bei einer erkannten Fehlanwendung des Reinigungsgerätes ein Fortschreiten der angezeigten Schritte so lange herausgezögert werden und in dem Status des vorausgehenden Anleitungsschrittes verbleiben, bis der Nutzer Korrekturen der Geräteanwendung beziehungsweise Geräteeinstellung vornimmt, d.h. die gemessenen Daten erkennen lassen, dass nun die Voraussetzungen für den Fortgang der Anleitung beziehungsweise der Reinigungstätigkeit vorliegen.During the course of the steps in the instructions, the user is asked to carry out one or more device settings and/or one or more device applications. The device settings include, but are not limited to, a performance of an electrical consumer of the cleaning device, a delivery quantity of a liquid application device and/or cleaning agent application device, a speed or oscillation frequency of a soil processing element processing a surface, a position of a sealing element of a flow channel, a flow cross section a flow channel, and others. The device applications include, but are also not limited to, connecting the cleaning device to an accessory, in particular a suction nozzle and/or cleaning brush and/or a wiping element, applying a liquid to a surface to be cleaned, and moving the cleaning device over the surface to be cleaned , carrying out the cleaning activity over a certain period of time or others. A step of the instructions may also include a combination of one or more device settings and one or more device applications, such as operating a blower at a specific power level, connecting a specific accessory to a base device, and moving the cleaning device back and forth over the device being cleaned Area. The instructions with the chronologically sequential steps can be structured in a modular manner. This means that each step that involves the user interacting with the cleaning device or an accessory can result in a plurality of alternative subsequent steps, with the subsequent step depending on how the user carried out the previous step. This means that the next displayed step of the application depends on the evaluation result of the control and evaluation device, namely on whether the measured device parameters match a predefined reference. Before each progression of the instructions, a decision is made as to which of the alternative subsequent steps will be presented to the user. This can be particularly relevant if the device parameters can occupy a certain parameter range. For example, with a measured value in an upper area of the reference range, a different subsequent step can occur than in the case of a device parameter in a lower area of the reference range. Furthermore, for example, if incorrect use of the cleaning device is detected, progression of the displayed steps can be delayed and remain in the status of the previous instruction step until the user makes corrections to the device application or device setting, that is, the measured data show that the requirements for the progress of the instructions or the cleaning activity is available.
Neben dem zuvor beschriebenen Verfahren wird mit der Erfindung des Weiteren ein Reinigungsgerät mit einer Kommunikationsschnittstelle vorgeschlagen, welches eingerichtet ist, ein zuvor beschriebenes Verfahren auszuführen. Die zuvor erläuterten Merkmale und Vorteile des erfindungsgemäßen Verfahrens ergeben sich somit auch für das vorgeschlagene Reinigungsgerät, sodass zur Vermeidung von Wiederholungen hier auf eine nochmalige Beschreibung verzichtet wird. Es versteht sich, dass das Reinigungsgerät zur Ausführung des Verfahrens nicht nur über eine Kommunikationsschnittstelle verfügen kann, sondern vielmehr auch über eine Steuer- und Auswerteeinrichtung, welche eine Geräteeinstellung und/ oder Geräteanwendung durch den Nutzer überwacht und das Fortschreiten der Anleitung beziehungsweise die Ausgabe eines Hinweises an den Nutzer veranlasst. Darüber hinaus kann das Reinigungsgerät auch eine Vielzahl unterschiedlicher Detektionseinrichtungen aufweisen, um einen Geräteparameter zu messen, welcher Aufschluss über eine bestimmte Geräteeinstellung und/oder Geräteanwendung gibt. Das Reinigungsgerät kann des Weiteren ein von einem Nutzer handgeführtes Gerät oder ein im Wesentlichen autonom arbeitendes Gerät, insbesondere ein sich selbsttätig fortbewegender Reinigungsroboter, sein.In addition to the method described above, the invention also proposes a cleaning device with a communication interface, which is set up to carry out a previously described method. The previously explained features and advantages of the method according to the invention also apply to the proposed cleaning device, so that a further description is omitted here in order to avoid repetition. It is understood that the cleaning device can not only have a communication interface to carry out the method, but also a control and evaluation device which monitors a device setting and/or device application by the user and the progress of the instructions or the issuance of a notice sent to the user. In addition, the cleaning device can also have a variety of different detection devices in order to measure a device parameter, which provides information about a specific device setting and/or device application. The cleaning device can furthermore be a device hand-held by a user or a device that operates essentially autonomously, in particular a cleaning robot that moves automatically.

Das externe Endgerät 4 ist hier beispielsweise als Mobiltelefon ausgebildet. Alternativ kann das externe Endgerät 4 jedoch auch ein anderes, bevorzugt mobiles, externes Endgerät 4 sein. Insbesondere kann es vorgesehen sein, als Endgerät 4 einen Tabletcomputer, einen Laptop oder ähnliches zu verwenden. Das externe Endgerät 4 weist vorzugsweise in üblicher Art und Weise ein Display 11 auf, welches besonders bevorzugt als Touchscreen ausgebildet ist. Über dieses Display 11 kann der Nutzer dann sowohl Informationen empfangen, als auch Eingaben tätigen, sodass das Display 11 gleichzeitig als Kommunikationsschnittstelle 3 des externen Endgerätes 4 dient. Das externe Endgerät 4 steht mit dem Reinigungsgerät 1 in Kommunikationsverbindung. Dazu verfügen das Reinigungsgerät 1 und das externe Endgerät 4 über nicht weiter dargestellte Kommunikationsmodule, beispielsweise WLAN-Module, Bluetooth-Module oder andere. Gemäß einer Ausführung können die Kommunikationsmodule des Reinigungsgerätes 1 und des externen Endgerätes 4 in ein Heimnetzwerk des Nutzers eingebunden sein.

Auf dem externen Endgerät 4 und dem Reinigungsgerät 1 ist des Weiteren eine Applikation installiert, um das erfindungsgemäße Verfahren auszuführen. In das Kommunikationsnetzwerk kann des Weiteren auch ein Server (nicht dargestellt) eingebunden sein, welcher beispielsweise Informationen über Reinigungstätigkeiten 5 des Reinigungsgerätes 1 enthalten kann, beispielsweise Informationen über Schritte 9, welche im Rahmen einer Reinigungstätigkeit 5 auszuführen sind. Diesen Schritten 9 zugeordnet können auch Geräteparameter gespeichert sein, welche das Reinigungsgerät 1 zum Zeitpunkt der Ausführung des jeweiligen Schrittes 9 aufzuweisen hat. Die Daten können in dem Server zentral gespeichert werden und somit von anderen Geräten des Heimnetzwerkes, insbesondere auch dem Reinigungsgerät 1 und dem externen Endgerät 4, abgerufen werden. Alternativ, und dies bevorzugt, sind die Daten jedoch zumindest in einem lokalen Speicher des Reinigungsgerätes 1 gespeichert. Insbesondere weist der Speicher des Reinigungsgerätes 1 Informationen über eine Mehrzahl von gespeicherten Reinigungstätigkeiten 5 auf, welche das Reinigungsgerät 1 ausführen kann. Zu jeder Reinigungstätigkeit 5 ist zumindest eine Geräteeinstellung 6 und/oder zumindest eine Geräteanwendung 7 gespeichert, welche der Nutzer selbst auszuführen hat. Der Speicher des Reinigungsgerätes 1 beziehungsweise des zentralen Servers weist darüber hinaus eine Anleitung 8 zum Ausführen der Reinigungstätigkeit 5 auf. Diese Anleitung 8 kann dem Nutzer auf der Kommunikationsschnittstelle 2 des Reinigungsgerätes 1 und/oder der Kommunikationsschnittstelle 3 des externen Endgerätes 4 angezeigt werden. Die Anleitung 8 kann in Textform und/ oder Bildform und/ oder Videoform und/oder Audioform vorliegen und eine Mehrzahl von Schritten 9 enthalten, die zeitlich aufeinanderfolgend von dem Nutzer auszuführen sind. Hierzu wird später noch mit Bezug zu den
Das Reinigungsgerät 1 weist des Weiteren eine oder bevorzugt mehrere Detektionseinrichtungen (nicht näher dargestellt) auf, welche einen Geräteparameter des Reinigungsgerätes 1 messen können. Ein Geräteparameter kann beispielsweise eine Spannung, Stromstärke, Drehzahl, Frequenz, Temperatur, ein Flüssigkeitsdurchfluss, ein Füllstand, eine Energieaufnahme eines elektrischen Verbrauchers oder ähnliches sein. Die Geräteparameter sind solche, welche durch eine Geräteeinstellung 6 und/ oder eine Geräteanwendung 7 durch den Nutzer verursacht werden, beispielsweise durch eine Geräteeinstellung 6, wie eine von dem Nutzer über die Bedieneinrichtung 18 des Reinigungsgerätes 1 gewählte Leistung eines Antriebsmotors für das Bodenbearbeitungselement 12 oder für ein Sauggebläse des Reinigungsgerätes 1. Die Detektionseinrichtung kann des Weiteren auch einen durch eine Geräteanwendung 7 verursachten Geräteparameter detektieren, beispielsweise, dass der Nutzer das Reinigungsgerät 1 mit einem bestimmten Zubehör 13 verbunden hat. Hierzu kann die Detektionseinrichtung beispielsweise einen Codescanner aufweisen, welcher einen Code eines mit dem Basisgerät 14 korrekt verbundenen Zubehörs 13 lesen kann. Eine Geräteanwendung 7 kann beispielsweise auch eine Bewegung des Reinigungsgerätes 1 über eine zu reinigende Fläche sein, wobei die Bewegung mittels eines Bewegungssensors detektiert wird oder ähnliches.The cleaning device 1 further has one or preferably several detection devices (not shown in detail), which can measure a device parameter of the cleaning device 1. A device parameter can, for example, be a voltage, current, speed, frequency, temperature, liquid flow, fill level, energy consumption of an electrical consumer or similar. The device parameters are those which are caused by a device setting 6 and/or a
Die Erfindung im Rahmen des hier dargestellten Ausführungsbeispiels funktioniert nun so, dass der Nutzer zunächst über die Kommunikationsschnittstelle 3 des externen Endgerätes 4, d.h. durch Berühren des Displays 11, eine von mehreren auswählbaren Reinigungstätigkeiten 5 wählt, die er mittels des Reinigungsgerätes 1 ausführen möchte. Als Reinigungstätigkeiten 5 sind gemäß
