Description

field of technology

The invention relates to a method for setting at least one parameter range of a device parameter of the soil cultivation device that is available on a soil cultivation device for processing an area and is dependent on a soil type of the area to be processed, the parameter range having a defined range of values that can be selected by the user for processing the area amounts of the device parameter.

In addition, the invention relates to a soil cultivation device with a control device which is designed to carry out such a method, as well as a system with a soil cultivation device and a terminal external to the soil cultivation device, an application being installed on the external terminal which is used to control a method of the aforementioned Type is trained.

State of the art

Methods of the aforementioned type are known in the prior art and are usually carried out by a manufacturer of the soil cultivation device in order to set parameter ranges defined on the soil cultivation device for operating the soil cultivation device for area cultivation. Suitable parameter ranges are predefined for common household surfaces to be processed, in particular floor types laid there such as carpets, wooden floors, tiled floors or other, within whose parameter limits a user can set a device parameter of the floor processing device can be adjusted to process the surface. For example, an adjustable device parameter can be a speed of a rotating cleaning brush, a suction power of a fan of the floor processing device or others. The user can select the respective device parameter via an actuating element on the soil processing device, for example via a rotary knob, a touchscreen, a slide switch or similar. The actuating element can be adjusted as desired between a minimum amount and a maximum amount for the respective device parameter. Furthermore, it is also known to provide several such actuating elements on a soil cultivation device so that the user has the opportunity to set different device parameters for processing an area. A method according to the preamble of claim 1 is, for example, in DE-U-20210567 disclosed.

Although the aforementioned methods and corresponding soil cultivation devices have proven themselves in the state of the art, they are only adapted by the manufacturer to a limited number of different areas to be processed, so that there may also be areas that do not fall into any of the preset categories and are therefore not optimally processed can. Alternatively, the user of the soil cultivation device would have to manually try out device parameters without knowing which ones offer the optimal conditions for cultivating the respective soil area.

Summary of the invention

Based on the stated prior art, it is therefore the object of the invention to develop a method of the aforementioned type in such a way that the user can optimally adjust the soil cultivation device to individual areas to be processed.

To solve this problem, it is proposed that the user moves the tillage device over the area to be worked during an adjustment process, whereby during the movement of the tillage device a limit device parameter that depends on the condition of the area is automatically set, which when used for the cultivation of the area becomes one a previously defined error case is determined, and the parameter range is automatically set based on the determined limit device parameter, in that the limit device parameter defines a range end of the parameter range.

According to the invention, the user is thus given the opportunity to adapt the soil cultivation device to the requirements of his household, in particular the types of soil laid there. As is known, it is advantageous to make different settings of the floor processing device for different types of floor coverings, for example different carpets, different hard floors, such as tiled floors, wooden floors, PVC and other. The different settings affect different device parameters that are particularly advantageous for processing the respective surface. Processing the surface can, for example, be vacuum cleaning, wet or dry wiping, polishing, grinding, waxing or similar. The user can thus calibrate his personal tillage device to the existing floor coverings in his home in order to achieve the best possible tillage. This eliminates the disadvantage represented in the prior art that preset parameter ranges on a commercially available soil cultivation device can basically only optimally serve a finite proportion of possible soil types. Due to the generalization involved, some types of flooring may not be processed optimally, as the user has to choose one of several presets, which may then not be optimally tailored to their own floor coverings. According to the invention In this method, the user is instructed to move the tillage implement over the area to be worked for an adjustment process, so that properties of the ground surface being driven over or the resulting behavior of the tillage implement can be determined. This in turn leads to a determination of the optimal parameter range for the area.

For a soil cultivation activity, a device parameter that is optimal for the area can be adjusted by the user between certain range limits, depending on whether, for example, particularly gentle, particularly intensive, particularly fast, particularly thorough cleaning or similar is desired. A device parameter that can be adjusted by the user is, for example, a suction power of a blower or a speed of a cleaning brush. While the user guides the tillage device over the area to be worked later as part of a setting process for the parameter ranges, the relevant device parameter of the tillage device is either automatically adjusted by a control device of the tillage device, or the user is instructed by the tillage device or a terminal device linked to it, to adjust the device parameters yourself. The device parameter is preferably adjusted automatically, starting from a minimum limit device parameter up to a maximum limit device parameter, at which an error occurs that the user and/or a detection device of the soil processing device can detect. The minimum limit device parameter can, for example, have the amount zero, but can also be individually set to a different amount if the "zero" amount of the device parameter or another small amount causes an error. It can also be provided that the user first specifies rough minimum and maximum limits of the parameter range. For example, the user could predefine the type of soil for the area to be worked, for example, that the area is a floor covering that does not adhere to a subsurface. This means that relatively high amounts of brush speeds as well as a moderate value for a volume flow of a suction fan can be specified immediately. In the case of a very deep-pile floor or fur, for example, the speed of a cleaning brush could basically be set to zero and only a volume flow of a suction fan could be adjusted. The subsequent process for fine-tuning the parameter range then takes place as described according to the invention. Furthermore, in this context it can preferably be provided that the limit device parameter is the amount of the device parameter at which no error occurred last time. This means that the occurrence of an error can be ruled out with a high degree of probability. An error case is not to be understood in the strict sense, but can be a specific situation that the user defines as a reason for the setting process to be aborted. An “error case” can also be, for example, a manual termination of the setting process, which in the narrower sense does not generally represent an error. Likewise, certain device states can also represent a user-defined error case, for example because a noise emission of the floor processing device or a current consumption of an electrical consumer of the floor processing device exceeds a desired amount.

In addition to the setting process described above, the method can also provide the user with prefabricated parameter ranges for certain types of surfaces for selection, from whose parameter limits the setting process described can then be started. The predefined settings can, for example, also be stored in a memory depending on the user, so that a specific preselection is made available to a respective user. In any case, the predefined settings are not binding, but can also be rejected or varied by the user. Furthermore, predefined settings can be used be overwritten. It is also possible for the parameter ranges set as part of the setting method according to the invention to be changed or overwritten, so that the user has the opportunity to repeat a setting process at any time. This is particularly recommended if the user changes floor coverings in their home, if they have changed due to wear or something similar.

In particular, it is proposed that as part of the setting process, two limit device parameters defining the range ends of the same parameter range are determined by changing the device parameter from a minimum amount, which can still be used without an error occurring, to a maximum amount, which can still be used without an error occurring is applicable, is varied. The device parameter can be varied either in discrete amount steps or continuously. If, for example, two or more device parameters that a user usually wants to set are essential for surface processing, the setting process can proceed in such a way that a parameter range for a first device parameter is first determined, while a second device parameter is kept constant. As soon as this parameter range is set, the constant second device parameter can then be set to an increased constant amount and the first device parameter can in turn be varied to determine the relevant range limits. In this way, two or more device parameters can be adjusted depending on each other.

It is particularly advantageously proposed that the user sets the parameter range using an application installed on a terminal external to the soil cultivation device. As part of the setting process, the application can instruct the user to carry out certain actions to vary the respective device parameters. Alternatively, the application can fully automatically control a variation of the respective device parameter on the soil cultivation device. For this purpose, the external terminal device containing the application is connected to the soil processing device via a communication connection, for example via a WLAN or Bluetooth connection. In particular, both the soil processing device and the external device can be integrated into the user's home network and communicate with each other via it. The application installed on the external device preferably provides a user interface on a touchscreen of the device through which the user can make manual entries and/or retrieve information. The user can also be offered predefined basic settings for certain types of soil on a display of the external device, so that the user can start a setting process based on predefined rough limit device parameters of a provisionally defined parameter range.

Particularly advantageously, the application can control a predefined calibration process on the soil cultivation device, which includes that the limit device parameter to be set on the soil cultivation device is determined by successively approaching the controlled device parameter to the limit device parameter defined by the occurrence of the error. The application thus directly controls the adjustment process of the soil cultivation device and acts on a control device of the soil cultivation device. In addition, the application can also monitor the occurrence of a predefined error case. However, it is also possible for the monitoring of an error to be carried out by an evaluation device of the soil cultivation device itself. The evaluation device of the soil processing device can then report the detected error to the application of the external terminal, so that the application can link the previously set parameter amounts to the occurrence of the error and advantageously also save them.

Furthermore, it is proposed that the device parameters include a suction volume flow of a fan of the floor processing device, a speed of a rotating floor processing element, a frequency of a vibrating floor processing element, a speed of movement of the floor processing device over the area to be worked and / or an amount of liquid applied by the floor processing device to the area to be worked is set. The aforementioned adjustable device parameters relate to those which are regularly relevant for the processing quality of certain types of soil. If the floor processing device is, for example, a vacuum cleaner, relevant device parameters are, in particular, a suction volume flow of a blower and a speed or oscillation frequency of a floor processing element. In the case of wet mopping devices, the amount of liquid applied to a surface to be worked or a floor processing element is particularly relevant. In addition, processing quality also depends on the speed of movement of an automatically moving soil cultivation device over the area to be processed. In the case of particularly cultivation-intensive soil types, it makes sense to keep the speed of movement of the soil cultivation device over the area to be processed as low as possible so that the exposure time per area is as large as possible.

As previously suggested, one or more error cases are predefined. These error cases are used to define the range limits of the parameter range to be set. In particular, errors can be defined as a decrease in a suction volume flow of a fan of the floor cultivation device below a minimum amount, a blocking of a movable floor cultivation element, a decrease in the speed of movement of the floor cultivation device below a minimum amount, an increase in the energy consumption of an electrical consumer of the floor cultivation device above a maximum amount, an increase in a sliding resistance of the floor processing device over a maximum amount, a lifting of a floor covering from the surface to be worked, a sound emission of the floor processing device exceeding a maximum amount, a moisture level of the area to be worked exceeding a maximum amount, a moisture level of a floor processing element of the floor processing device exceeding a maximum amount and /or receiving a stop command from a user that ends the setting process. The aforementioned list is not exhaustive. Other error cases can also be predefined within the scope of the invention. Error cases are usually those that lead to the soil cultivation device not functioning properly or mean that a user of the soil cultivation device has to cancel it manually. The occurrence of an error defined in this way leads to an end to the setting process according to the invention. In relation to conventional suction cleaning devices, the setting process can be carried out, for example, until an error occurs, which means that the maximum amounts for a volume flow of a suction fan and a speed of a cleaning brush have been reached, such that a cleaning brush blocks, for example due to excessive intervention of the cleaning brush into a carpet that a pushing force to be applied by a user to move the floor processing device is too high, that a negative pressure in the floor processing device increases excessively, for example when an unglued carpet is lifted from a surface and then completely covers a suction channel of the cleaning device, or that the user The setting process is completed manually by pressing a button on the cleaning device or an external device.

The error case is preferably defined by a user before the setting process or alternatively can be specified by the manufacturer. If the manufacturer of the soil cultivation device has already predefined error cases, these are preferably in a local memory of the soil cultivation device stored or can be accessed from a manufacturer's server by the soil processing device or an external device in communication with it.

In addition, it can be provided that the determined limit device parameter is stored in a memory of the soil processing device and/or a memory of the external terminal and/or a memory of an external server. In addition, it is proposed that the set parameter range is assigned to an actuating element of the soil cultivation device that can be manually operated by the user, whereby the user selects an amount of the device parameter desired for soil cultivation of the area within the limits of the preset parameter range by actuating the actuation element. The associations between certain actuating elements of the soil cultivation device and the optimal parameter ranges determined by the setting process can be stored in a memory of the soil cultivation device and/or a memory of the external terminal and/or also a memory of an external server. In particular, an assignment can be made by an application installed on an external device to, for example, one of several selectable levels of an actuating element. Each level can be optimized for a specific floor type, such as hard floors, short-pile carpets, long-pile carpets or others. Once created and saved, assignments can be deleted again, but advantageously remain available in a memory for future access. This means that once assignments have been set, they can be set again. Assignments between actuating elements and predefined parameter areas are particularly advantageously synchronized via a server so that they continue to be available for access by a user, for example when a mobile device is changed.

In addition to the method according to the invention described above for setting at least one parameter range available on the soil cultivation device for processing an area, the invention also proposes a soil cultivation device with a control device which is designed to carry out a method of the aforementioned type. In addition, a system with a soil cultivation device and a terminal external to the soil cultivation device is also proposed, with an application being installed on the external terminal which is designed to control such a setting process for the parameter range. To avoid repetition, reference is made in this regard to the previous statements on the method according to the invention. The features and advantages described there also apply accordingly to the soil cultivation device or system according to the invention.

Description of the embodiments

Figure 1 shows one of a large number of possible embodiments for a floor processing device 1 according to the invention. The floor processing device 1 is designed here as a cleaning device that is manually operated by a user, namely here as a manually operated vacuum cleaner. However, the invention can also be used in self-moving soil cultivation devices 1. The floor processing device 1 is used to clean different surfaces 2, which can include, for example, hard floors and carpets, in particular high-pile carpets, short-pile carpets, wooden parquet, wooden floorboards, tiles, cork, PVC and others. The soil cultivation device 1 has a base device 17, in which, for example, a blower, a blower motor and a dust chamber are arranged, not visible here. The base device 17 is detachably connected to an attachment 15, which serves to act on the surface 2 to be processed. Here, the attachment 15 is, for example, a suction nozzle with a suction mouth 16 and a soil processing element 10 assigned to the suction mouth 16. The soil processing element 10 here is, for example, a cleaning brush rotating about an axis oriented essentially parallel to the surface 2. Starting from the base device 17, a handle 14 with a handle 18 extends - facing away from the attachment 15 - by means of which a user of the floor processing device 1 can guide the floor processing device 1 in a usual back and forth movement over the surface 2 to be worked. The handle 14 is advantageously designed to be telescopic, so that the user can adjust its length to his body size in order to handle the soil cultivation device 1 comfortably. The handle 18 has a plurality of actuating elements 12, which are designed here, for example, as push buttons. Alternatively Other types of actuating elements 12 can also be provided, for example slide switches, rotary switches, toggle switches or similar. By actuating the actuating elements 12, the user can set a desired mode of the soil cultivation device 1 in order to process the area 2. For example, one mode can be an energy-saving eco mode, in which the blower motor is operated as energy-saving as possible. Another mode can be, for example, an intensive mode, which is suitable for removing even stubborn dirt from the surface 2. Furthermore, for example, a quick mode can also be provided, which cleans the floor surface 2 in the shortest possible period of time. Each mode is characterized by an available parameter range 3 with a plurality of different amounts of a device parameter 4, which relate, for example, to a power consumption of the blower motor, a speed of the soil cultivation element 10, a setting of sealing elements in the area of the suction mouth 16 of the soil cultivation device 1 and others . The parameter range 3 can, for example, contain low and high values for a speed of the actuating element 12, which the user can optionally select for soil cultivation. The settings of the respective mode, in particular the device parameters 4, are preferably stored in a local memory of the floor processing device 1 and are retrieved from the memory when an actuating element 12 is actuated and used by a control device of the floor processing device 1 to control the corresponding units of the floor processing device 1, for example to control the blower motor or a drive motor for the tillage element 10. The modes can also be optimized for certain types of soil in the area 2 to be worked. For example, an eco mode can be optimized for processing a hard floor, while an intensive mode is optimized for processing a carpet. In addition, the floor processing device 1 can, for example, also have actuating elements 12 which control other combinations, for example carpet mode Eco, carpet mode Intensive, Hard Floor Eco, Hard Floor Intensive and others. The different modes are usually predefined by a manufacturer of the tillage device 1 and, in the case of tillage devices 1 according to the prior art, are stored in a memory of the tillage device 1. In contrast, the invention proposes an alternative, which is explained in more detail below.

Figure 2 shows an external terminal 9, which here is, for example, a mobile phone. Furthermore, the external terminal 9 can also be another, preferably mobile, terminal 9. In particular, it can also be provided to use a tablet computer, a laptop or similar as the terminal device 9. The external terminal 9 preferably has a display 13 in the usual manner, particularly preferably designed as a touchscreen, via which a user can both receive information and make entries. To carry out a method according to the invention, the external terminal 9 is in communication with the soil cultivation device 1. For this purpose, the soil cultivation device 1 and the external terminal 9 have communication modules, for example WLAN modules, Bluetooth modules or others. Particularly preferably, a communication module of the soil processing device 1 and a communication module of the external terminal 9 are integrated into a user's home network. An application is also installed on the external terminal 9 in order to carry out the method steps according to the invention. A server 11 is also preferably included in the communication network (see for example Figure 4 ) integrated, so that data relating to the settings of the tillage device 1 can be stored in the server 1 and can be accessed there by other participants in the home network, in particular the tillage device 1 and the external terminal 9.

Using the application installed on the external device 9, the user can optimize his floor processing device 1 to the individual floor coverings of the surfaces 2 to be cleaned in his household. For this purpose, device parameters 4 of the tillage device 1, which are used to till the areas 2, are adjusted to the individual properties of the areas 2 in the user's household, i.e. H. calibrated. However, the soil processing device 1 can also be calibrated in the same way on surfaces 2 which do not belong to a household environment, but rather to a commercial environment, for example in a shop, an office, a warehouse or others. The functionality of the invention remains unaffected.

Using the application installed on the external device 9, the user can now adjust his tillage device 1 to his individual areas 2 in just a few simple steps and thus achieve an optimal tillage result. In the case of a cleaning device, an optimal soil cultivation result can be understood, for example, based on a quantity of particles picked up by the soil cultivation device 1. Furthermore, the invention ensures that the user experiences optimal handling of the soil cultivation device 1 and that all components of the soil cultivation device 1 function smoothly. This includes, for example, that floor processing elements 10, such as the rotating cleaning brush here, do not block, that the floor processing device 1 can be moved over the surface 2 to be processed with little effort, that carpets lying loosely on a surface are not lifted off the surface, and the like. First of all, the user has to start the application on his external device 9 and carry out the displayed calibration steps, which are used to set at least one parameter range 3 of a device parameter 4 of the floor processing device 1 available on his floor processing device 1. In Figure 2 are merely examples two different adjustable device parameters 4 are displayed, namely here a speed of the brush (soil cultivation element 10) and a volume flow, which can be generated by a fan of the soil cultivation device 1. After starting the application, the user is preferably asked to move the soil cultivation device 1 over the relevant area 2 to which the soil cultivation device 1 should be optimally adjusted. By moving the tillage device 1 during the calibration process, a dynamic load on the tillage device 1 can be taken into account, which then occurs in the same way later when the tillage device 1 is used for actual tillage of this area 2. The application then fully automatically controls a calibration process on the soil cultivation device 1, which includes that the speed of the soil cultivation element 10 and the volume flow of the fan in discrete steps or alternatively also continuously from preferably a low amount of the respective device parameter 4 to a higher amount of the device parameter 4 be changed. For example, the procedure can be such that initially only the volume flow is varied, while a lowest speed of the soil cultivation element 10 is kept constant. In successive steps, the speed of the tillage element 10 can then be set to a higher amount than in the previous step and then the volume flow can be varied again from a low amount to a higher amount, while the speed of the tillage element 10 is also kept constant. The lowest speed of the tillage element 10, from which the calibration process is started, can, for example, have the amount zero. Alternatively, however, it is also possible for the user to specify a starting speed from which the setting process for the parameter range 3 of the volume flow or the speed of the soil processing element 10 is started. Furthermore, provisional rough minimum or maximum values can also be used for the setting process Limit device parameters 5, 6 must be set in advance and accessed by the user in the application. For example, such a presetting can distinguish between hard floors and carpets, so that the setting process for the parameter range 3 of the device parameter 4 starts, for example, directly in areas that make sense for a hard floor, or in areas that make sense for a carpet. This allows the overall calibration process to be shortened in time. The default settings can be stored in the application or on a server 11 which the application accesses. Such presettings can also be defined depending on the country and/or market, so that different calibration start parameters and calibration end parameters make sense for a soil cultivation device 1 that is operated in Asia, for example, than in Europe, for example. The user can preferably also delete, modify or similar the saved presets using the application.

Furthermore, so-called error cases are stored in the application by the manufacturer of the soil cultivation device 1 or by the user, which should lead to the termination of a setting step during the calibration. By defining such an error case or several error cases, it is achieved that the user can later, ie after completed calibration, operate the soil cultivation device 1 only in a parameter range 3 of the respective device parameter 4, which enables trouble-free and successful processing of the area 2. In the present example, the error case can be defined as a blocking of the rotating tillage element 10 or an occurrence of a maximum pushing force which the user must apply to move the tillage implement 1 over the surface 2. Other error cases can be characterized, for example, by a maximum amount for the volume flow, a maximum amount for a negative pressure prevailing at the suction mouth 16, a lifting a floor covering from a subsurface or others. In addition, an error case can also be a manual termination of the calibration process by the user, although this does not describe an error in the strict sense. The user can end the calibration process for the respective device parameter 4, for example via a button on the soil cultivation device 1 or via an entry on the display 13 of the external terminal 9. If a predefined error case is then detected during the setting process for the usable parameter range 3 of the device parameter 4, the calibration step is ended and preferably the last setting before the error occurred is adopted as the limit device parameter 5, 6. This limit device parameter 5, 6, which enables optimal processing of the surface 2, defines a lower end of the range 7 or an upper end of the range 8 of the parameter range 3, which is later available to the user when using the soil cultivation device 1. The user can also use the application to select the actuating element 12 on the soil processing device 1 via which the device parameter 4 should be controllable.

In Figure 2 the user starts the calibration process for the tillage device 1, for example, from the lower limit device parameter 5 "zero", which indicates the lower end of the range 7 of the parameter ranges 3 for the device parameters 4 "brush speed" and "volume flow". The parameter areas 3 for “brush speed” and “volume flow” are then calibrated as explained above. As in Figure 3 shown, an "error case" occurs, for example, at a speed which here corresponds to 20 percent of a maximum possible speed of the tillage element 10. This speed is then stored as an upper limit device parameter 6 for the speed of the soil cultivation element 10. Likewise, with regard to the volume flow of the blower, an error occurs at 80 percent of the maximum possible volume flow of the soil processing device 1. This amount at 80 percent is saved as upper limit device parameter 6 for the volume flow. The stored amounts for the lower limit device parameters 5 and upper limit device parameters 6 of the device parameters 4 "brush speed" and "volume flow" are then sent to the soil processing device 1 and the external server 11 (see Figure 4 ) transmitted. The saved settings are advantageously stored permanently in both the soil processing device 1 and the external terminal 9 and the server 11, but can be deleted or changed there by the user. As a result, the user can, for example, retrieve previously saved settings from the server 11 when replacing his external device 9. The user can then use the saved settings for the parameter ranges 3 that can be used via the assigned actuating elements 12 in order to achieve an optimal soil processing result for their individual areas 2.

Just as in the manner shown above, the user can also set certain combinations of base devices 17 and attachments 15 to individual surfaces 2. It is clear to the person skilled in the art that the set device parameters 4 can not only be a speed of a soil cultivation element 10 or a volume flow of a blower, but rather also any other type of device parameter 4, such as a frequency of a vibrating soil cultivation element 10, a speed of movement automatically via a surface 2 moving soil cultivation device 1, an amount of liquid which is applied to the surface 2 to be processed or to a soil cultivation element 10 of the soil cultivation device 1 or others. Furthermore, error cases other than those mentioned above can also be defined.
