At least one interaction element, linked to the cleaning recommendation, for the user is providable on the output unit for transmitting interaction information to the at least one control unit, in particular in dependence on the cleaning recommendation.
The foregoing summary and the following description may be better understood in conjunction with the drawing figures, of which:
Although the invention is illustrated and described herein with reference to specific embodiments, the invention is not intended to be limited to the details shown. Rather, various modifications may be made in the details within the scope and range of equivalents of the claims and without departing from the invention.
The present invention relates to a high pressure cleaning system comprising a high pressure cleaning appliance that has a pump assembly, at least on accessory that is in or is bringable into flow connection with a high pressure outlet of the pump assembly, wherein the high pressure cleaning appliance is operable with at least one variable operating parameter, an input unit, at least one control unit coupled to the input unit, and an output unit coupled to the at least one control unit, wherein an object to be cleaned is specifiable by way of the input unit and a cleaning recommendation is providable on the output unit by the at least one control unit in dependence on the specification, said cleaning recommendation comprising an instruction for using an accessory and/or the value of at least one operating parameter, and wherein at least one interaction element for the user is providable, linked to the cleaning recommendation, on the output unit for transmitting interaction information to the at least one control unit, in particular in dependence on the cleaning recommendation.
The versatility of the high pressure cleaning system in accordance with the invention results from the fact that it is possible for the user to, by way of the at least one interaction element, transmit interaction information to the at least one control unit in response to the cleaning recommendation that is outputted. The quality of the at least one interaction element and the interaction information transmittable to the at least one control unit may, in particular, be dependent on the cleaning recommendation. In a preferred embodiment, a dialogue between the user and at least one control unit can preferably thereby be established by the user being able to react to the dynamic cleaning recommendation and advantageously being able to adapt and, in particular, refine said cleaning recommendation for his/her needs, if necessary. This makes it possible to express a best possible cleaning recommendation with a view to the cleaning task, in particular by means of a dialogue-like or workflow-like exchange of information between the user and the high pressure cleaning system, wherein the user can preferably simultaneously be instructed to perform the cleaning. Alternatively or in addition, provision is favorably made that upon actuation of the interaction element, cleaning instructions are provided, for example in a workflow-like or dialogue-like manner, by the at least one control unit on the output unit, which cleaning instructions instruct the user in the use of the high pressure cleaning system with a view to a best possible cleaning.
The output unit advantageously is or comprises a display unit, wherein an image display is preferably provided and the cleaning recommendation as well as the at least one interaction element can be visually represented.
The cleaning recommendation for the accessory and/or the value of the at least one operating parameter may be providable, e.g., in graphical form, text form, and/or by voice output and may comprise, in particular, graphical elements and/or text and/or audio elements.
For example, the at least one interaction element is providable and, in particular, displayable on the output unit in the form of a button, a selection element, or a rotary and/or slide control. By actuating the button, selecting an action provided on the selection element, or setting the control with which, for example, the value of at least one operating parameter can be varied, the user is able to interact with the high pressure cleaning system.
In a preferred embodiment, provision may be made that the output unit is of acoustic configuration. “Interaction element” is thus not limited to a visually represented and, for example, haptically actuatable element. The cleaning recommendation can be provided on the acoustic output unit, for example by speech output.
In a corresponding manner, provision may be made that the at least one interaction element is providable by a voice output with the possibility of responding to the voice output. An interaction, for example, by means of voice input by the user can thus be made possible.
Provision may be made that the at least one interaction element is providable on the input unit by optically linking a display element to a physical actuation element. For example, a physical actuation element in the form of a button or the like may be provided on the input unit. This actuation element may be visually linked as a “softkey” to a display element that is displayable on the output unit. For example, the user is notified that a certain interaction is enabled by actuating the actuation element.
It is advantageous if the cleaning recommendation comprises an instruction for use of an accessory together with the value of at least one operating parameter. The user thus obtains a comprehensive, useful recommendation to achieve a best possible cleaning result.
In particular, provision may be made that the cleaning recommendation may comprise an indication relating to the values of a plurality of operating parameters, also for achieving a best possible cleaning result.
Provision may be made, in particular, that more than one interaction element is providable. The interaction elements may be constituted in different ways with respect to their effect, such that different interaction information is transmittable to the control unit depending on the actuation. In the context of the present disclosure, the phrase “the at least one interaction element” can thus be interpreted to mean “at least one interaction element of the at least one interaction element”.
Provision may be made that the high pressure cleaning system comprises more than one control unit. Thus, in the context of the present disclosure, the phrase “the at least one control unit” can be interpreted to mean “at least one control unit of the at least one control unit”.
The at least one interaction element preferably comprises a confirmation element, by the actuation of which a confirmation information of the user is transmittable to the at least one control unit. By actuating the confirmation element, the user can thus communicate to the control unit that he/she has taken notice of the cleaning recommendation and, in particular, acknowledge same. In a way, the user accepts, by means of the interaction element, the cleaning recommendation by the control unit.
It is favorable if the cleaning recommendation comprises an indication relating to the value of at least one operating parameter and if the high pressure cleaning appliance is settable to the value of the at least one operating parameter upon confirmation by the at least one interaction element. The user can react to the cleaning recommendation and accept the suggested value of the at least one operating parameter. The high pressure cleaning appliance is set to this value in a user-friendly manner.
It is understood that information can be exchanged between the input unit and the high pressure cleaning appliance as necessary. For example, interaction information that is made on the input unit is transmitted to a control unit and can be transmitted by the latter directly or indirectly to the high pressure cleaning appliance. Alternatively, the information may be transmitted by the input unit, e.g., to a control unit arranged in the high pressure cleaning appliance.
It is advantageous if the cleaning recommendation comprises an indication relating to the value of at least one operating parameter and if the at least one interaction element is a changing element, by way of which the value of the at least one operating parameter can be changed by the user. By way of the changing element, for example configured as a rotary or slide control or as a selection element, the user can provide feedback to the high pressure cleaning system that he/she considers a different value for the at least one operating parameter to be advantageous.
It is favorable if, in the case of the last mentioned embodiment, information relating to this is transmitted to the at least one control unit and the high pressure cleaning appliance is settable to the changed value of the at least one operating parameter. This increases the user friendliness of the high pressure cleaning system. As explained above, information can be transmitted to the high pressure cleaning appliance as necessary.
It is advantageous if the cleaning recommendation comprises an indication relating to the value of at least one operating parameter and if the high pressure cleaning appliance, in the absence of an actuation of the at least one interaction element for a predetermined or predeterminable time after provision of the cleaning recommendation, is set to the value of the at least one operating parameter. It is made possible for the user to give feedback to the high pressure cleaning system by way of the at least one interaction element. In the present case, it is favorable, however, if after a certain period of time without feedback, the value of the at least one operating parameter is set, automatically to an extent, without further action by the user.
It may prove to be advantageous if a plurality of cleaning recommendations connected to a respective at least one interaction element are providable and if the cleaning recommendations comprise at least one indication relating to the use of an accessory, wherein the accessories of different cleaning recommendations differ from one another. In practice, provision may well be made that mutually different accessories can be used to clean a particular object. Thus, the at least one control unit may provide more than one cleaning recommendation.
In the latter case, it is advantageous if the respective at least one interaction element forms a confirmation element or a selection element, upon actuation of which information for using the accessory linked to said interaction element is transmittable to the control unit. This makes it possible for the user to communicate to the control unit that he/she selects one of the accessories for the cleaning. The value of at least one operating parameter is thereby favorably provided by way of the interaction. Here, provision may be made that the user confirms the suggested value of the operating parameter or transmits a value on his/her own. In practice, it may be in fact be such that values of operating parameters for different accessories that are each suited for cleaning the object may differ from one another.
Overall, it is advantageous if the value of at least one operating parameter is variable by means of the at least one interaction element.
It is favorable if the high pressure cleaning appliance is settable to the value of the at least one operating parameter without prior confirmation or change by the user. This makes it possible to set the high pressure cleaning appliance to the value in accordance with the cleaning recommendation without intervention by the user and thus effectively automatically, thereby increasing the user friendliness of the high pressure cleaning system. Provision may be made that the setting of the high pressure cleaning appliance takes place directly and without waiting for a duration of time to pass, as was previously described.
The at least one interaction element may comprise a request element, upon actuation of which a request is transmittable to the control unit to provide a different cleaning recommendation. For example, an accessory is suggested to the user that he/she, by virtue of his/her own experience, find to be less suitable. The user can request a different cleaning recommendation by means of the interaction element. Alternatively, provision may be made that the user is not in possession of the suggested accessory and requests the proposal of a new cleaning recommendation with an alternative recommendation for the accessory.
Provision may be made that the cleaning recommendation comprises an indication relating to the use of an accessory and that the at least one interaction element comprises an acquisition element, upon actuation of which an acquisition request of the user relating to the accessory is transmittable to a spatially remote data processing device. For example, the user in the last-mentioned case in which he/she is not in possession of the suggested accessory can transmit an acquisition request to acquire the suggested accessory. The at least one control unit can transmit the acquisition request to a data processing device. There, the acquisition request can, for example, be automatically processed in order to initiate a shipment of the accessory to the user.
The at least one operating parameter can advantageously be set manually by the user on the high pressure cleaning appliance or on an operating unit thereof.
Provision may be made that the value of at least one operating parameter is controllable and/or regulatable during the operation of the high pressure cleaning appliance.
The at least one interaction element is favorably providable together with the cleaning recommendation on the output unit. This makes it easier for the user to handle the high pressure cleaning system.
Provision may be made that the at least one interaction element is providable on the output unit only after instruction by the user by way of the input unit or after expiration of a predeterminable or predetermined time. For example, the cleaning recommendation is provided to the user on the output unit and the interaction element is provided only after triggering a respective request of the user by way of the input unit. Alternatively or in addition, provision may be made that the at least one interaction element is provided only after a certain period of time.
In a preferred embodiment, the cleaning recommendation may comprise a plurality of accessories. In practice, it may be advantageous if the object to be cleaned is cleaned with different accessories that are used one after the other. For example, for cleaning a motor vehicle, first a flat jet nozzle may be used for pre-cleaning, then a foam nozzle together with a cleaning chemical for applying foam to the vehicle, then a washing brush for fine cleaning the vehicle, and finally a flat jet nozzle for removing the cleaning residues. In the cleaning of a bicycle, for example, first a flat jet nozzle may be used for pre-cleaning and then a cleaning brush for fine cleaning.
A plurality of accessories as a constituent part of the cleaning recommendation may therefore be provided, in particular, for use in chronological succession, preferably according to cleaning instructions that are providable on the output unit by the at least one control unit. As explained in the following, the user can be instructed with cleaning instructions for using and exchanging the accessories, for example by means of a guide provided by way of the output unit.
In a preferred embodiment of the invention, the at least one interaction element may comprise, e.g., a request element, upon actuation of which by the user at least one cleaning instruction for cleaning the object is providable on the output unit by the at least one control unit. The provision of the cleaning instruction facilitates the user's handling of the high pressure cleaning system. A guide assisting the user in cleaning is preferably provided.

Provision may be made that the value of at least one operating parameter is limitable by the high pressure cleaning appliance in dependence on the accessory contained in the cleaning recommendation. For example, the pressure of the cleaning liquid or a pressure level for the cleaning liquid is limited in dependence on the accessory and/or the object to be cleaned in order to avoid damage to the object.
It is favorable if it is determinable by a control unit of the high pressure cleaning appliance during use thereof which value of at least one operating parameter is used and/or which accessory is used. In particular, the value of at least one operating parameter is limitable by the high pressure cleaning appliance in dependence on the accessory used, which is preferably contactlessly detectable, for example by means of an RFID technology.
It is favorable if it is determinable by the control unit of the high pressure cleaning appliance whether the value of at least one operating parameter and/or the accessory used deviates from the cleaning recommendation, for example upon the start of operation or at a later time. This makes it possible, in particular, to detect a misoperation of the high pressure cleaning appliance and to initiate countermeasures if necessary.
Upon determining the deviation, for example, at least one of the following is performable:
It is understood that the components of the high pressure cleaning system may have required communication interfaces for transmitting information among one another and with external devices.
Provision may be made that the high pressure cleaning appliance communicates, in particular wirelessly, with further devices of the user, specifically with further cleaning appliances.
The high pressure cleaning system advantageously comprises a storage unit, wherein usage information of the high pressure cleaning appliance is transmittable by a control unit to the storage unit for storage and is storable therein. For example, a protocol of the usage of the high pressure cleaning appliance can be created.
The use of usage information to detect the consumption of usage components, for example the consumption of cleaning agents and/or the wear of accessories, is conceivable.

The accessory device 62 comprises a control unit 76 and a storage unit 78. Stored in the storage unit 78 is a user application program, configured as an app. The user application program can be executed by the control unit 76 and enables the user to interact with the high pressure cleaning system 10 in an intuitive manner. In particular, cleaning recommendations on the basis of the object to be cleaned can be requested by the high pressure cleaning system 10 and the high pressure cleaning appliance 12 can be automatically and/or manually set for operation by way of the accessory device 62.
In a preferred embodiment, the exchange of information between the accessory device 62 and the high pressure cleaning appliance 12 takes place by way of a point-to-point connection, for example by means of Bluetooth. In a different advantageous embodiment, provision may be made that the high pressure cleaning appliance 12 and the accessory device 62 communicate in a common network. For example, a ZigBee network is used, which is provided by a Gateway that is not depicted in the drawing and which itself can communicate by way of wireless network with a home network router, which in turn enables an internet connection.
In a preferred embodiment, the high pressure cleaning system 10 further comprises a data processing device 80 arranged spatially remote from the high pressure cleaning appliance 12 and from the accessory device 62, which data processing device 80 may itself have a control unit 82. Further, a storage unit 84 may be arranged spatially remote. It is understood that the storage unit 84 can be formed by or integrated into the data processing device 80, in particular the control unit 82. The same applies to the storage unit 78 and the control unit 76.
In the present example, the data processing device 80 and the storage unit 84 are implemented by means of a symbolically depicted cloud service 86. In this case, the cloud service 86 may be, in particular, a plurality of data processing devices that are in communication connection with one another.

The input unit 66 may have, e.g., a different kind of detection unit with which the object to be cleaned is detectable, for example by means of RFID technology. The reference numeral 100 designates a corresponding detection unit in
The interaction of the user with the high pressure cleaning system 10 for obtaining a cleaning recommendation may take place by way of the accessory device 62 with a user application program, for example in one of the manners described in the following.
For example, it is described how the control unit 76, the control unit 82, or the control unit 32 can process information. Here, provision may be made, in particular, that the processing of information, for example the provision of cleaning recommendations, the receipt of interaction information and/or the forwarding thereof, is performed by only one of the control units or a combination of two or more control units, which may each be used for this purpose. For example, the cleaning recommendation is provided by the control unit 82 and transmitted to the accessory device 62. Possible interaction information can be detected by the control unit 76 of said accessory device and, for example, be transmitted directly or indirectly to the control unit 32 of the high pressure cleaning appliance 12 and/or the control unit 82.
The selection of the object to be cleaned can be carried out by way of the app. The exemplary representation of
The pictograms 102 displayed on the touchscreen 74 can be selected by the user. In the present example, it is assumed that the user touches the pictogram separately referenced with the reference numeral 104, said pictogram showing a wall or the like as an object to be cleaned.
The user then obtains a cleaning recommendation, presently by displaying on the display unit 68 of the touchscreen 74. To this end, the input is transmitted to a control unit of the high pressure cleaning system 10. For example, the control unit 82 is used for this purpose. The control unit 82 can load a cleaning profile stored in the storage unit 84. In a respective cleaning profile, it is stored, linked to the object to be cleaned, which accessory 38 and which values of operating parameters of the high pressure cleaning appliance 12 should preferably be used.
The corresponding cleaning recommendation can be transmitted by the control unit 82 to the accessory 62.
Alternatively or in addition, it is conceivable that the cleaning recommendation is provided by the control unit 32 or 76. Cleaning profiles can be stored, e.g., in the storage unit 78 of the accessory device 62.
In the case of a high pressure cleaning system of that kind, provision may be made that the external data processing device 80 and the storage unit 84 are omitted. Such a high pressure cleaning system in accordance with the invention is depicted in
It is favorable if, in addition, the value of at least one operating parameter is comprised by the cleaning recommendation 112. In the present case, it is shown by way of a symbol 116 that the pressure level 2 of the high pressure cleaning appliance 12 should advantageously be used.
In the present invention, it is favorable that, in addition, at least one interaction element for the user is provided with the cleaning recommendation 112. In the present case, an interaction element 118 for the user is displayed as a constituent part of the cleaning recommendation 112. The interaction element 118 is a confirmation element 119. By actuating the confirmation element 119, interaction information is transmitted to the control unit 32, 76, or 82.
In the present case, the interaction information may be merely an acknowledgment of the user that he/she acknowledges the recommendation for the value of the operating parameter “pressure”.
It is favorable if a setting of the high pressure cleaning appliance 12 in accordance with with the cleaning recommendation 112 is performed upon confirmation by the user. Here, in particular, the pressure level can be set to the value 2.
The interaction information of the user relating thereto can be transmitted directly or indirectly to the high pressure cleaning appliance 12 upon actuation of the confirmation element 119. For example, the control unit 76 receives the information and transmits it to the control unit 32, by which the pressure level is set according to the cleaning recommendation 112.
The transmission of the information to the high pressure cleaning appliance 12 may be effected by the accessory device 82 or by the data processing device 80 without or with intervention by the user.
A further interaction element 120 is configured as a changing element 121. By actuating the changing element 121, for example, a rotary or slide control 122 and 123, respectively, (on the right in
For example, an interaction element 124 may be provided as a constituent part of the cleaning recommendation 112. The interaction element 124 is a request element 125. By actuating the request element 125, the user can transmit interaction information to the control unit 82 with the request for the provision of a different cleaning recommendation. Said cleaning recommendation can then also be provided on the output unit 68.
A further interaction element 126 may be provided as a constituent part of the cleaning recommendation 112. In the present case, the interaction element 126 is an acquisition element 127. By actuating the acquisition element 127, the user can transmit an acquisition request to the data processing device 80. This is advantageous, for example, when the user is not in possession of the accessory 38 suggested according to the cleaning recommendation 112.
The control unit 82 can provide a plurality of cleaning recommendations in response to the cleaning request of the user. In addition to the cleaning recommendation 112, a further cleaning recommendation 128 is depicted exemplarily in
The cleaning recommendation 128, too, may comprise the interaction elements 118, 120, 124, and 126.
A cleaning recommendation 134 suggests by means of the pictogram 136 the use of the surface cleaning device 60 as an accessory 38. The pressure level 2 is suggested as the value for the operating parameter “pressure”.
A further cleaning recommendation 138, for example for pre-cleaning, suggests by means of the pictogram 140 the discharge unit 48 with the low pressure cleaning agent nozzle as an accessory 38. Moreover, the use of the container 34 with a cleaning chemical is suggested with the pictogram 142.
Level 1 is suggested for the operating parameter “pressure”. Level 1 is suggested for the operating parameter “admixing ratio” (symbol 143).
In the case of the cleaning recommendations that are exemplarily depicted in
By way of the at least one interaction element 118, 120, 124, and 126, in combination with the feedback of the control unit 82, 76, or 32 by way of the output unit 68, a dialogue of the user with the high pressure cleaning system 10 is possible. A cleaning recommendation can thereby be presented to the user in order to achieve a best possible cleaning result. At the same time, the user can be instructed to operate the high pressure cleaning appliance 12. It can thereby advantageously be ensured that the object to be cleaned is not damaged. For example, only an accessory 38 that does not cause any damage to the object is suggested.
For the purpose of the latter, it may be advantageous if the value of at least one operating parameter of the high pressure cleaning appliance 12 is limited in dependence on the accessory 38 that is suggested or used.
Provision may be made that the accessory 38 that is used and the value of at least one operating parameter is detected and, in particular, monitored. For example, misoperation by the user can be caught by the high pressure cleaning appliance 12 or the pump assembly 14 being deactivated upon deviation from the cleaning recommendation. Alternatively or in addition, an indication can be provided to the user, for example on the high pressure cleaning appliance 12, on the operating unit 24, and/or on the output unit 68. Alternatively or in addition, the value of at least one operating parameter of the high pressure cleaning appliance 12 can be automatically set to the value in accordance with the cleaning recommendation. It can thereby be ensured, in particular, that a maximum value for the operating parameter is not exceeded.
In the case of misoperation, information relating to the use of the accessory 38 and the value of at least one operating parameter can be detected and, for example, transmitted to the storage unit 84 or 78 for storage. In dependence thereon, possible warranty exclusions may follow. It is also favorable if suggestions for improving the cleaning can be presented to the user.
Irrespective of possible misoperation, provision is favorably made that usage information from the high pressure cleaning appliance 12 can be transmitted and stored in one of the storage units 84 and 76, for example the usage duration, usage times, the use of the accessories 38, and/or values for at least one operating parameter.
In place of the above-described specification of the object to be cleaned by way of one of the pictograms 102, provision may be made that the app on the input unit 66 provides, for example, a text field for inputting the object, a selection list, or a depiction of the actual object.
For example, for the latter case, provision may be made, in particular, that a user profile for the user is stored in a storage unit 78 or 84. Linked to the user profile is, e.g., at least one individualized object to be cleaned. For example, not only a generic object “motor vehicle” is saved in the storage unit 78, 84 linked to the cleaning profile, but the actual object “motor vehicle of the user”.
In particular, information as to what quality the object has, for example which material, can be stored, linked to the individualized object. An optimized cleaning recommendation can be outputted in dependence on the quality.
In providing a user profile for the user, the information as to which accessories 38 the user possesses may be stored linked to said user profile. Provision may be made that the cleaning recommendation only considers those accessories 38 that the user actually possesses and are linked to his/her user profile. Cleaning recommendations that the user cannot implement can be avoided in this way.
Otherwise, provision may be made that the cleaning recommendation is provided independently of the saved accessories 38, here, in particular, the interaction element 126 as an acquisition element 127 being of importance for the user to acquire an accessory 38 that is not present.
The type of high pressure cleaning appliance 12 of which the user is in possession is advantageously saved in the user profile. The cleaning recommendations can be provided by the control unit 82, 76, or 32, preferably in dependence on the type of high pressure cleaning appliance 12 that is saved in order to ensure that accessories 38 are suggested which are compatible with the high pressure cleaning appliance 12.
Upon acquisition of the high pressure cleaning appliance 12, one or more accessories 38 may be a constituent part of basic equipment. By adding the high pressure cleaning appliance 12 to the user profile, it is possible in this way to automatically save in the user profile which accessories 38 the user possesses. These accessories 38 do not have to be further entered in the user profile.
By means of the digital camera 98, an image of the bicycle 144 can be created. Image information relating thereto is forwarded from the accessory device 62 to the control unit 82.
Stored in the storage unit 82 are image processing algorithms, on the basis of which the object can be identified as a bicycle 144. The quality of the bicycle 144 can preferably also be determined, for example the material thereof and/or the degree of soiling thereof.
On the basis of the determined information, the control unit 32, 76, or 82 can provide a cleaning recommendation on the accessory device 62. The information required for the cleaning recommendation may, for example, be correlated in the control unit 82. Otherwise, provision may be made that the information that the object is a bicycle 144 is transmitted to the accessory device 62, from which the information required for the cleaning recommendation are correlated.
Values for the at least one operating parameter can be transmitted from the accessory device 72 or from the control unit 76 or 82 directly or indirectly to the high pressure cleaning appliance 12.
At least one operating parameter can advantageously be set automatically on the high pressure cleaning appliance 12. The arrows denoted with the reference numerals 146, 147, and 148 schematically and exemplarily illustrate the course of the procedure.
Provision may alternatively be made that the control unit 76 directly analyzes the image information and determines that the object is a bicycle 144. The cleaning recommendation can be transmitted by the control unit 76 on the basis of this information and preferably be transmitted to the high pressure cleaning appliance 12 for setting at least one operating parameter.
Provision may be made, in particular, that the quality of the object can be determined on the basis of the information from one of the detection units 100, 149, or 98, in the form of the digital camera. On the basis of the transmitted information, the control unit can determine, e.g., of what material the object consists. In dependence on the quality, the cleaning recommendation can be provided with a view to a best possible cleaning result.
Alternatively to the optical detection of the object to be cleaned, a different kind of detection may be conceivable. For example, a detection by means of RFID technology is used.
In the example depicted in
Moreover, a guide for the user for handling and, in particular, for servicing the high pressure cleaning appliance 12, which has also been detected by the digital camera 98, is provided by means of image information 154.
