Definitions
- the invention relates to a high-pressure cleaning system with the features of claim 1.
- High pressure cleaning systems and discharge units are for example from the DE 10 2006 009 855 A1 known.
- High-pressure cleaning systems have a high-pressure cleaning device with which a cleaning liquid, for example water, can be pressurized.
- the high-pressure cleaning device comprises a pump and a motor driving the pump.
- Cleaning fluid to be pressurized can be delivered to the pump through a pump inlet and the cleaning fluid pressurized from the pump can be delivered through a pump outlet.
- Different discharge units can be brought into fluid connection with the pump outlet, so that the pressurized cleaning liquid can be directed onto a surface to be cleaned by means of the discharge unit which is in fluid connection with the pump outlet.
- High-pressure cleaning systems of this type are used for cleaning a wide variety of surfaces, for example for cleaning floor surfaces, building facades and vehicles.
- different discharge units are used.
- the type of cleaning for example a rough cleaning, an abrasive cleaning or a foam cleaning, also influences the choice of the optimal discharge unit, that with the pump outlet of the high-pressure cleaning device should be brought into fluid connection in order to achieve the best possible cleaning result.
- the discharge units differ from one another by their discharge characteristics, for example by a different outlet pressure of the cleaning liquid, a different jet shape, or also by the addition of a cleaning chemical which is added to the cleaning liquid.
- the pressure of the cleaning liquid should be selected to be significantly lower than that of a discharge unit with which the most punctiform cleaning liquid jet possible for one abrasive cleaning should be aimed at a surface.
- the volume flow of the cleaning liquid should also be adapted to the discharge unit used in order to achieve the best possible cleaning result.
- the user can often find the optimum conveying parameters of the high-pressure cleaning device for different discharge units in the operating instructions for the high-pressure cleaning device.
- the operating instructions are often not available to the user if he wants to put the high-pressure cleaning device into operation at a location.

With the help of the control unit, optimal cleaning parameters, which are assigned to the identification code that is read in each case, can be automatically determined for regulating the operation of the liquid pump with optimal cleaning parameters.
- the object of the present invention is to develop a high-pressure cleaning system and a discharge unit of the type mentioned at the outset in such a way that the best possible cleaning result can be achieved in a simple manner, the user being able to manually control the dispensing of cleaning liquid pressurized and the discharge unit used can be recorded.
- the high-pressure cleaning system has a detection unit, with the aid of which the type of discharge unit currently in fluid communication with the pump outlet can be detected.
- the detection unit is connected in a signal-conducting manner to the control device of the high-pressure cleaning device, so that a signal corresponding to the type of discharge unit currently being used can be transmitted from the detection unit to the control device, which then automatically sends at least one conveying parameter of the high-pressure cleaning device to the currently Adapts the coming type of discharge unit.
- the adaptation can take place, for example, in such a way that the control device controls the motor pump unit in such a way that the pump provides a specific outlet pressure of the cleaning liquid and / or a specific volume flow of the pressurized cleaning liquid.
- An adaptation can also take place in such a way that an admixing device of the high-pressure cleaning device is controlled by the control device in order to add a cleaning chemical to the cleaning liquid, a specific dosage of the cleaning chemical being achieved.

Description
Die Erfindung betrifft ein Hochdruckreinigungssystem mit den Merkmalen von Patentanspruch 1.The invention relates to a high-pressure cleaning system with the features of claim 1.
Hochdruckreinigungssysteme und Austragseinheiten sind beispielsweise aus der
Soll beispielsweise eine Austragseinheit zum Einsatz kommen, mit deren Hilfe der unter Druck gesetzten Reinigungsflüssigkeit eine Reinigungschemikalie, beispielsweise eine Seifenlösung, beigemischt werden kann, so sollte der Druck der Reinigungsflüssigkeit deutlich geringer gewählt werden als bei einer Austragseinheit, mit der ein möglichst punktförmiger Reinigungsflüssigkeitsstrahl für eine abrasive Reinigung auf eine Fläche gerichtet werden soll. Auch der Volumenstrom der Reinigungsflüssigkeit sollte zur Erzielung eines möglichst guten Reinigungsergebnisses an die jeweils zum Einsatz kommende Austragseinheit angepasst werden.If, for example, a discharge unit is to be used, with the aid of which a cleaning chemical, for example a soap solution, can be added to the pressurized cleaning liquid, the pressure of the cleaning liquid should be selected to be significantly lower than that of a discharge unit with which the most punctiform cleaning liquid jet possible for one abrasive cleaning should be aimed at a surface. The volume flow of the cleaning liquid should also be adapted to the discharge unit used in order to achieve the best possible cleaning result.
Die jeweils optimalen Förderparameter des Hochdruckreinigungsgeräts für unterschiedliche Austragseinheiten kann der Benutzer häufig der Betriebsanleitung des Hochdruckreinigungsgeräts entnehmen. Allerdings steht die Betriebsanleitung dem Benutzer häufig nicht zur Verfügung, wenn er das Hochdruckreinigungsgerät an einem Einsatzort in Betrieb setzen möchte. Außerdem ist das Studium der Betriebsanleitung zeitraubend. Es können deshalb Fälle auftreten, bei denen der Benutzer das Hochdruckreinigungsgerät mit einem Förderparameter betreibt, der nicht optimal an die aktuell zum Einsatz kommende Austragseinheit angepasst ist, so dass kein gutes Reinigungsergebnis erzielt werden kann.The user can often find the optimum conveying parameters of the high-pressure cleaning device for different discharge units in the operating instructions for the high-pressure cleaning device. However, the operating instructions are often not available to the user if he wants to put the high-pressure cleaning device into operation at a location. In addition, studying the operating instructions is time-consuming. There can therefore be cases in which the user operates the high-pressure cleaning device with a conveying parameter that is not optimally adapted to the discharge unit currently being used, so that a good cleaning result cannot be achieved.
Aus der Veröffentlichung
Aufgabe der vorliegenden Erfindung ist es, ein Hochdruckreinigungssystem sowie eine Austragseinheit der eingangs genannten Art derart weiterzubilden, dass auf einfache Weise ein möglichst gutes Reinigungsergebnis erzielt werden kann, wobei der Benutzer die Abgabe von unter Druck gesetzter Reinigungsflüssigkeit manuell steuern kann und die zum Einsatz kommende Austragseinheit erfasst werden kann.The object of the present invention is to develop a high-pressure cleaning system and a discharge unit of the type mentioned at the outset in such a way that the best possible cleaning result can be achieved in a simple manner, the user being able to manually control the dispensing of cleaning liquid pressurized and the discharge unit used can be recorded.
Diese Aufgabe wird durch ein Hochdruckreinigungssystem mit den Merkmalen von Patentanspruch 1 gelöst.This object is achieved by a high-pressure cleaning system with the features of patent claim 1.
Beim erfindungsgemäßen Hochdruckreinigungssystem kann auf einfachere Weise ein gutes Reinigungsergebnis erzielt werden, da zumindest ein Förderparameter des Hochdruckreinigungsgeräts von der Steuereinrichtung selbsttätig an den Typ der aktuell zum Einsatz kommenden Austragseinheit anpassbar ist. Zu diesem Zwecke weist das Hochdruckreinigungssystem eine Erfassungseinheit auf, mit deren Hilfe der Typ der aktuell mit dem Pumpenauslass in Fluidverbindung stehenden Austragseinheit erfassbar ist. Die Erfassungseinheit ist signalleitend mit der Steuereinrichtung des Hochdruckreinigungsgeräts verbunden, so dass von der Erfassungseinheit ein dem Typ der aktuell zum Einsatz kommenden Austragseinheit entsprechendes Signal an die Steuereinrichtung übertragen werden kann, die daraufhin selbsttätig zumindest einen Förderparameter des Hochdruckreinigungsgeräts an den aktuell zum Einsatz kommenden Typ der Austragseinheit anpasst. Die Anpassung kann beispielsweise derart erfolgen, dass die Steuereinrichtung die Motorpumpeneinheit derart steuert, dass die Pumpe einen bestimmten Ausgangsdruck der Reinigungsflüssigkeit bereitstellt und/oder einen bestimmten Volumenstrom der unter Druck gesetzten Reinigungsflüssigkeit. Eine Anpassung kann auch derart erfolgen, dass von der Steuereinrichtung eine Beimischeinrichtung des Hochdruckreinigungsgeräts gesteuert wird, um der Reinigungsflüssigkeit eine Reinigungschemikalie beizumischen, wobei eine bestimmte Dosierung der Reinigungschemikalie erzielt wird. Die Handhabung des erfindungsgemäßen Hochdruckreinigungssystems gestaltet sich daher relativ einfach, und dennoch kann ein sehr gutes Reinigungsergebnis erzielt werden, ohne dass es für den Benutzer erforderlich ist, zur Erzielung eines möglichst guten Reinigungsergebnisses die für die aktuell zum Einsatz kommende Austragseinheit optimalen Förderparameter des Hochdruckreinigungsgeräts manuell einzugeben.In the high-pressure cleaning system according to the invention, a good cleaning result can be achieved in a simpler manner, since at least one conveying parameter of the high-pressure cleaning device can be automatically adapted by the control device to the type of discharge unit currently being used. For this purpose, the high-pressure cleaning system has a detection unit, with the aid of which the type of discharge unit currently in fluid communication with the pump outlet can be detected. The detection unit is connected in a signal-conducting manner to the control device of the high-pressure cleaning device, so that a signal corresponding to the type of discharge unit currently being used can be transmitted from the detection unit to the control device, which then automatically sends at least one conveying parameter of the high-pressure cleaning device to the currently Adapts the coming type of discharge unit. The adaptation can take place, for example, in such a way that the control device controls the motor pump unit in such a way that the pump provides a specific outlet pressure of the cleaning liquid and / or a specific volume flow of the pressurized cleaning liquid. An adaptation can also take place in such a way that an admixing device of the high-pressure cleaning device is controlled by the control device in order to add a cleaning chemical to the cleaning liquid, a specific dosage of the cleaning chemical being achieved. The handling of the high-pressure cleaning system according to the invention is therefore relatively simple, and nevertheless a very good cleaning result can be achieved without it being necessary for the user to manually enter the optimal delivery parameters of the high-pressure cleaning device for achieving the best possible cleaning result .

Die Fluidverbindung von der Austragseinheit zum Pumpenauslass des Hochdruckreinigungsgeräts erfolgt über eine Spritzpistole. Mittels der Spritzpistole kann der Benutzer die Abgabe von unter Druck gesetzter Reinigungsflüssigkeit manuell steuern. Die Spritzpistole weist ein manuell betätigbares Ventil auf, das in einem Durchgangskanal angeordnet ist, der sich von einem Pistoleneinlass bis zu einem Pistolenauslass erstreckt. Dem Pistoleneinlass kann über eine Druckleitung, beispielsweise einen Druckschlauch, vom Hochdruckreinigungsgerät unter Druck gesetzte Reinigungsflüssigkeit zugeführt werden. Die Reinigungsflüssigkeit durchströmt den Durchgangskanal der Spritzpistole, sofern das im Durchgangskanal angeordnete Ventil seine Offenstellung einnimmt. Vom Pistolenauslass kann die unter Druck gesetzte Reinigungsflüssigkeit zur Austragseinheit gelangen, die an den Pistolenauslass angeschlossen werden kann.According to the invention, the high-pressure cleaning system has a spray gun with a manually operable valve which is arranged in a through-channel extending from a gun inlet to a gun outlet, the gun inlet being able to be brought into fluid communication with the pump outlet of the high-pressure cleaning device via a pressure line, preferably a pressure hose and wherein the discharge unit can be connected to the gun outlet, and wherein the detection unit is arranged on the spray gun. The fluid connection from the discharge unit to the pump outlet of the high-pressure cleaning device takes place via a spray gun. The spray gun allows the user to manually control the delivery of pressurized cleaning fluid. The spray gun has a manually operable valve, which is arranged in a through-channel, which extends from a gun inlet to a gun outlet. The gun inlet can be supplied by a high-pressure cleaning device with pressurized cleaning fluid via a pressure line, for example a pressure hose. The cleaning fluid flows through the through-channel of the spray gun, provided that the valve arranged in the through-channel assumes its open position. The pressurized cleaning fluid can come from the gun outlet to the discharge unit, which can be connected to the gun outlet.
Am Pistolenauslass und an der Austragseinheit können miteinander zusammenwirkende Verbindungsglieder angeordnet sein. Die Verbindungsglieder können beispielsweise eine Bajonettverbindung ausbilden.Interacting connecting links can be arranged on the gun outlet and on the discharge unit. The connecting links can, for example, form a bayonet connection.
Zusätzlich zu dem die Abgabe von unter Druck gesetzter Reinigungsflüssigkeit steuernden Ventil weist die Spritzpistole auch die Erfassungseinheit auf, mit deren Hilfe die an die Spritzpistole angeschlossene Austragseinheit erfasst werden kann.In addition to the valve controlling the delivery of pressurized cleaning liquid, the spray gun also has the detection unit, with the aid of which the discharge unit connected to the spray gun can be detected.
Die Erfassung kann berührungsbehaftet oder auch berührungslos erfolgen.The detection can be done by touch or without contact.

Insbesondere kann vorgesehen sein, dass mehrere Förderparameter von der Steuereinrichtung selbsttätig an die jeweils zum Einsatz kommende Austragseinheit anpassbar sind. Beispielsweise kann bei Einsatz einer Austragseinheit, mit deren Hilfe ein Gemisch aus Reinigungsflüssigkeit und Reinigungschemikalie ausgetragen werden kann, sowohl eine bestimmte Dosierung der Reinigungschemikalie als auch der Druck der Reinigungsflüssigkeit und günstigerweise auch der Volumenstrom der Reinigungsflüssigkeit von der Steuereinrichtung selbsttätig angepasst werden.In an advantageous embodiment of the high-pressure cleaning system according to the invention, it is advantageous if the at least one delivery parameter that can be adapted by the control device to the discharge unit currently being used, the pressure of the cleaning liquid, the volume flow of the cleaning liquid and / or the dosage of a cleaning chemical that can be mixed with the cleaning liquid includes. In particular, it can be provided that several control parameters can be automatically adapted by the control device to the discharge unit used in each case. For example, when using a discharge unit, with the aid of which a mixture of cleaning liquid and cleaning chemical can be discharged, both a specific dosage of the cleaning chemical and the pressure of the cleaning liquid and advantageously also the volume flow of the cleaning liquid can be automatically adjusted by the control device.
Günstigerweise umfasst das Hochdruckreinigungssystem eine Anzeigevorrichtung, an der der mindestens eine angepasste Förderparameter einem Benutzer anzeigbar ist. Der Benutzer erhält somit eine optisch, akkustisch oder auch auf andere Weise, beispielsweise haptisch erfassbare Information über den mindestens einen Förderparameter, der von der Steuereinrichtung selbsttätig an die aktuell zum Einsatz kommende Austragseinheit angepasst wurde.The high-pressure cleaning system advantageously includes a display device on which the at least one adapted conveying parameter can be displayed to a user. The user thus receives optically, acoustically or in some other way, for example haptically ascertainable information about the at least one conveying parameter that was automatically adapted by the control device to the discharge unit currently being used.
Bevorzugt ist der mindestens eine angepasste Förderparameter vom Benutzer veränderbar. Dies gibt dem Benutzer die Möglichkeit, den mindestens einen Förderparameter, der von der Steuereinrichtung auf Grundlage des von der Erfassungseinheit bereitgestellten Signals angepasst wurde, manuell zu verändern, falls der Benutzer der Auffassung ist, der von der Steuereinrichtung angepasste Förderparameter könne zur Lösung einer bestimmten Reinigungsaufgabe für einen konkreten Fall noch optimiert werden.The at least one adapted conveying parameter can preferably be changed by the user. This gives the user the option of manually changing the at least one conveying parameter that was adjusted by the control device on the basis of the signal provided by the detection unit if the user believes that the conveying parameter adjusted by the control device can be used to solve a specific cleaning task be optimized for a specific case.

Im Speicherglied der Steuereinrichtung sind mehrere Förderparameter hinterlegt, die jeweils einem Typ von Austragseinheit zugeordnet sind, um mit dem jeweiligen Typ von Austragseinheit ein möglichst gutes Reinigungsergebnis zu erzielen. Die Steuereinrichtung erhält von der Erfassungseinheit ein Signal entsprechend dem aktuell erfassten Typ von Austragseinheit. In Abhängigkeit von dem erfassten Typ wird dann aus dem Speicherglied der diesem aktuell erfassten Typ von Austragseinheit zugeordnete Förderparameter ausgelesen, und entsprechend diesem ausgelesenen Förderparameter wird dann das Hochdruckreinigungsgerät von der Steuereinrichtung gesteuert.In a particularly preferred embodiment of the high-pressure cleaning system according to the invention, the control device has a memory element, in which delivery parameters adapted to a type of discharge unit are stored, wherein depending on the type of discharge unit currently detected by the detection unit, at least one delivery parameter adapted to this type from the Memory element can be read out. Several conveying parameters are stored in the memory element of the control device, each of which is assigned to a type of discharge unit in order to achieve the best possible cleaning result with the respective type of discharge unit. The control device receives a signal from the detection unit corresponding to the currently detected type of discharge unit. Depending on the type detected, the conveying parameters associated with this currently detected type of discharge unit are then read out from the memory element, and the high-pressure cleaning device is then controlled by the control device in accordance with this read-out delivery parameter.
Wie bereits erwähnt, können unterschiedliche Austragseinheiten zum Einsatz kommen. Bei einer bevorzugten Ausgestaltung der Erfindung ist die Austragseinheit ausgestaltet als Hochdruck-Flachstrahldüse, Hochdruck-Rotordüse, Hochdruck-Punktstrahldüse, Niederdruck-Reinigungsmitteldüse, Schaumdüse, Waschbürste oder Flächenreiniger, wobei der Flächenreiniger eine Haube aufweist und eine in der Haube beweglich angeordnete Düsenanordnung, die von der unter Druck stehenden Reinigungsflüssigkeit antreibbar ist. Je nachdem welcher Typ von Austragseinheit aktuell mit dem Pumpenauslass des Hochdruckreinigungsgeräts in Fluidverbindung steht, wird von der Steuereinrichtung zumindest ein Förderparameter des Hochdruckreinigungsgeräts an diesen Typ von Austragseinheit angepasst.As already mentioned, different discharge units can be used.

Die Austragseinheit weist bei einer vorteilhaften Ausführungsform der Erfindung ein den Typ der Austragseinheit kennzeichnendes Identifikationselement auf, das von der Erfassungseinheit berührungsbehaftet oder berührungslos erfassbar ist. Wird die Austragseinheit mit dem Pumpenauslass in Strömungsverbindung gebracht, so kann das den Typ der Austragseinheit kennzeichnende Identifikationselement von der Erfassungseinheit erfasst werden und es kann von der Erfassungseinheit eine entsprechende Information an die Steuereinrichtung übertragen werden.In an advantageous embodiment of the invention, the discharge unit has an identification element which characterizes the type of discharge unit and which can be detected by the detection unit by touch or without contact. If the discharge unit is brought into flow connection with the pump outlet, the identification element which characterizes the type of discharge unit can be detected by the detection unit and corresponding information can be transmitted from the detection unit to the control device.
Es kann vorgesehen sein, dass die Erfassungseinheit das Identifikationselement berührungsbehaftet erfasst. Bei einer derartigen Ausgestaltung findet ein mechanischer Kontakt zwischen der Erfassungseinheit und dem Identifikationselement statt. Unterschiedliche Typen von Austragseinheiten charakterisierende Identifikationselemente können hierbei unterschiedliche mechanische Anordnungen ausbilden, die jeweils von einem Erfassungsorgan der Erfassungseinheit durch eine mechanische Kontaktierung nach Art eines Schlüssel-Schloss-Prinzips erfasst werden können.It can be provided that the detection unit detects the identification element with touch. In such an embodiment, mechanical contact takes place between the detection unit and the identification element. Different types of identification elements characterizing discharge units can form different mechanical arrangements, each of which can be detected by a detection element of the detection unit by mechanical contacting in the manner of a key-lock principle.
Von besonderem Vorteil ist es, wenn das den Typ der Austragseinheit kennzeichnende Identifikationselement von der Erfassungseinheit berührungslos erfassbar ist. Bei einer derartigen Ausgestaltung findet kein mechanischer Kontakt zwischen dem Identifikationselement und der Erfassungseinheit statt, vielmehr wird vom Identifikationselement ohne mechanischen Kontakt ein Signal an die Erfassungseinheit übertragen, das den Typ der Austragseinheit kennzeichnet.It is particularly advantageous if the identification element characterizing the type of discharge unit can be detected by the detection unit without contact. In such an embodiment, there is no mechanical contact between the identification element and the detection unit, rather a signal is transmitted from the identification element without mechanical contact to the detection unit, which characterizes the type of discharge unit.
Es kann beispielsweise vorgesehen sein, dass das Identifikationselement von der Erfassungseinheit elektrisch, magnetisch, elektromagnetisch, induktiv, kapazitiv, optisch oder auch mechanisch erfassbar ist.It can be provided, for example, that the identification element can be detected electrically, magnetically, electromagnetic, inductively, capacitively, optically or also mechanically by the detection unit.
Bei einer besonders bevorzugten Ausgestaltung der Erfindung weist das Identifikationselement ein von der Erfassungseinheit auslesbares Speicherglied auf. Im Speicherglied kann beispielsweise eine den Typ der Austragseinheit kennzeichnende Information hinterlegt sein, die von der Erfassungseinheit vorzugsweise berührungslos ausgelesen werden kann.In a particularly preferred embodiment of the invention, the identification element has a memory element that can be read out by the detection unit. For example, information identifying the type of discharge unit can be stored in the memory element and can be read out by the detection unit, preferably without contact.
Von besonderem Vorteil ist es, wenn im Speicherglied mindestens ein an den Typ der Austragseinheit angepasster Förderparameter gespeichert ist. Bei einer derartigen Ausgestaltung der Erfindung kann dem Speicherglied des Identifikationselements unmittelbar ein an den Typ der Austragseinheit angepasster Förderparameter entnommen werden. Dieser Förderparameter kann von der Erfassungseinheit an die Steuereinrichtung übertragen werden, die daraufhin das Hochdruckreinigungsgerät entsprechend diesem Förderparameter steuert. Eine derartige Ausgestaltung hat insbesondere den Vorteil, dass die Steuereinrichtung nicht eine Vielzahl von Förderparametern bereithalten muss, die jeweils an einen Typ von Austragseinheit angepasst sind, sondern die Steuereinrichtung erhält von der jeweils zum Einsatz kommenden Austragseinheit über die Erfassungseinheit unmittelbar den zur Erzielung eines möglichst guten Reinigungsergebnisses optimal an die Austragseinheit angepassten Förderparameter, auf dessen Grundlage die Steuereinrichtung dann das Hochdruckreinigungsgerät steuern kann. Beispielsweise kann im Speicherglied des Identifikationselements ein bestimmter Druck und/oder ein bestimmter Volumenstrom und/oder eine bestimmte Dosierung einer Reinigungschemikalie hinterlegt werden, die beim Einsatz der entsprechenden Austragseinheit ein gutes Reinigungsergebnis ermöglichen.It is particularly advantageous if at least one conveying parameter adapted to the type of discharge unit is stored in the storage element. In such an embodiment of the invention, a conveying parameter adapted to the type of discharge unit can be taken directly from the storage element of the identification element. This conveying parameter can be transmitted from the detection unit to the control device, which then controls the high-pressure cleaning device in accordance with this conveying parameter. Such an embodiment has the particular advantage that the control device does not have to have a large number of conveying parameters available, each of which is adapted to a type of discharge unit, but rather that the control device receives from the discharge unit used in each case directly via the detection unit in order to achieve the best possible one Cleaning results optimally adapted to the discharge unit conveying parameters, on the basis of which the control device can then control the high-pressure cleaning device. For example, in the memory element a certain pressure and / or a certain volume flow and / or a certain dosage of a cleaning chemical are stored in the identification element, which enable a good cleaning result when using the corresponding discharge unit.
Bei einer besonders bevorzugten Ausgestaltung der Erfindung ist das Identifikationselement als Transponder ausgebildet. Unter einem Transponder wird ein Funk-Kommunikationsglied verstanden, welches eingehende Signale aufnimmt und beantwortet. Derartige Transponder ermöglichen eine drahtlose Übertragung von Signalen zwischen dem Identifikationselement und der Erfassungseinheit, die zur drahtlosen Kommunikation mit dem Transponder ein Lesegerät aufweist. Zusätzlich zu einer Sende- und Empfangsantenne weist der Transponder ein Speicherglied auf, das mit der Sende- und Empfangsantenne in elektrischer Verbindung steht und vom Lesegerät der Erfassungseinheit ausgelesen werden kann.In a particularly preferred embodiment of the invention, the identification element is designed as a transponder. A transponder is understood to be a radio communication link that picks up and answers incoming signals.

Die Elektroeinrichtung kann ein von der Erfassungseinheit bereitgestelltes Signal aufnehmen und an die Steuereinrichtung des Hochdruckreinigungsgeräts übertragen. Die Übertragung des Signals von der Elektroeinrichtung an die Steuereinrichtung kann leitungslos erfolgen oder auch über eine Verbindungsleitung. Insbesondere eine Funkübertragung von Signalen von der Elektroeinrichtung zur Steuereinrichtung hat sich als vorteilhaft erwiesen.It is expedient if an electrical device is arranged on the spray gun and is connected to the detection unit in a signal-conducting manner. The electrical device can pick up a signal provided by the detection unit and transmit it to the control device of the high-pressure cleaning device. The signal can be transmitted from the electrical device to the control device in a line-less manner or via a connecting line. In particular, radio transmission of signals from the electrical device to the control device has proven to be advantageous.

Die Eingabevorrichtung kann beispielsweise in Form einer Tastatur ausgestaltet sein. Vorteilhafterweise umfasst die Elektroeinrichtung eine Anzeigevorrichtung zum Anzeigen von mindestens einem Förderparameter.

Wird dieser Förderparameter vom Benutzer manuell verändert, so kann auch diese Änderung an der Anzeigevorrichtung angezeigt werden.The electrical device of the spray gun advantageously has an input device for entering at least one delivery parameter. The input device can be configured, for example, in the form of a keyboard. The electrical device advantageously comprises a display device for displaying at least one conveying parameter. In particular, the conveying parameter adapted to the type of discharge unit currently being used can be displayed on the display device. If this conveying parameter is changed manually by the user, this change can also be displayed on the display device.

Das Identifikationselement ist günstigerweise elektrisch, magnetisch, elektromagnetisch, induktiv, kapazitiv, optisch oder mechanisch erfassbar. Bevorzugt weist das Identifikationselement ein Speicherglied auf. Das Speicherglied kann von einer Erfassungseinheit berührungsbehaftet oder berührungslos ausgelesen kann und im Speicherglied kann eine den Typ der Austragseinheit kennzeichnende Information hinterlegt sein.The disclosure also relates to a discharge unit for a high-pressure cleaning system of the type explained above, the discharge unit being able to be brought into fluid communication with the pump outlet of the high-pressure cleaning device in order to discharge cleaning liquid pressurized. In order to further develop the discharge unit in such a way that the best possible cleaning result can be achieved in a simpler manner, in a particularly preferred embodiment the discharge unit has an identification element that characterizes the type of discharge unit. The identification element can be detected by an assigned detection unit, as already explained above, and a signal corresponding to the type of the discharge unit detected can be transmitted from the detection unit to the control device of the high-pressure cleaning device, so that at least one conveying parameter of the high-pressure cleaning device is adapted to the type of discharge unit can be. The identification element can advantageously be detected electrically, magnetically, electromagnetically, inductively, capacitively, optically or mechanically. The identification element preferably has a memory element. The storage element can be read by a detection unit or can be read without contact, and information identifying the type of discharge unit can be stored in the storage element.
Es kann vorgesehen sein, dass im Speicherglied zumindest ein an den Typ der Austragseinheit angepasster Förderparameter gespeichert ist. Wie bereits erläutert, gibt dies die Möglichkeit, im Speicherglied zumindest einen Förderparameter zu hinterlegen, der zur Erzielung eines möglichst guten Reinigungsergebnisses optimal an die jeweilige Austragseinheit angepasst ist. Dieser Förderparameter kann von einer Erfassungseinheit ausgelesen und der Steuereinrichtung des Hochdruckreinigungsgeräts bereitgestellt werden, so dass die Steuereinrichtung das Hochdruckreinigungsgerät derart steuert, dass das Hochdruckreinigungsgerät den optimal an die Austragseinheit angepassten Förderparameter bereitstellt.It can be provided that at least one conveying parameter adapted to the type of discharge unit is stored in the storage element. As already explained, this makes it possible to store at least one conveying parameter in the storage element, which is optimally adapted to the respective discharge unit in order to achieve the best possible cleaning result. This delivery parameter can be read out by a detection unit and made available to the control device of the high-pressure cleaning device, so that the control device controls the high-pressure cleaning device in such a way that the high-pressure cleaning device provides the delivery parameters optimally adapted to the discharge unit.
Das Identifikationselement ist bei einer besonders bevorzugten Ausgestaltung der Erfindung als Transponder ausgebildet. Wie bereits erwähnt, handelt es sich bei einem Transponder um ein Funk-Kommunikationsglied, welches eingehende Signale aufnimmt und beantwortet. Die eingehenden Signale werden von der Erfassungseinheit bereitgestellt und die ausgehenden Signale werden von der Erfassungseinheit empfangen. Der Transponder kann eine eigene Energieversorgungseinrichtung aufweisen, beispielsweise eine Batterie. Besonders günstig ist es jedoch, wenn dem Transponder die Versorgungsenergie von der Erfassungseinheit bereitgestellt wird. Beispielsweise kann die Erfassungseinheit an den Transponder ein elektromagnetisches Signal übertragen, das zur Folge hat, dass im Transponder eine elektrische Spannung induziert wird. Derartige Transponder sind dem Fachmann an sich bekannt und bedürfen vorliegend keiner näheren Erläuterung.In a particularly preferred embodiment of the invention, the identification element is designed as a transponder. As already mentioned, a transponder is a radio communication link that receives and answers incoming signals. The incoming signals are provided by the acquisition unit and the outgoing signals are received by the acquisition unit. The transponder can have its own energy supply device, for example a battery. However, it is particularly favorable if the supply energy is made available to the transponder by the detection unit. For example, the detection unit can transmit an electromagnetic signal to the transponder, which has the consequence that an electrical voltage is induced in the transponder. Such transponders are known per se to the person skilled in the art and do not require any further explanation in the present case.
Die Austragseinheit ist vorteilhafterweise ausgestaltet als Hochdruck-Flachstrahldüse, Hochdruck-Rotordüse, Hochdruck-Punktstrahldüse, Niederdruck-Reinigungsmitteldüse, Schaumdüse, Waschbürste oder Flächenreiniger, wobei letzterer eine Haube aufweist, in der eine Düsenanordnung beweglich angeordnet ist, die von unter Druck stehender Reinigungsflüssigkeit antreibbar ist.The discharge unit is advantageously designed as a high-pressure flat jet nozzle, high-pressure rotor nozzle, high-pressure point jet nozzle, low-pressure cleaning agent nozzle, foam nozzle, washing brush or surface cleaner, the latter having a hood in which a nozzle arrangement is movably arranged, which can be driven by cleaning fluid under pressure .
Von besonderem Vorteil ist es, wenn die Austragseinheit ein mechanisches Verbindungsglied aufweist, das mit einer Spritzpistole mechanisch verbindbar, insbesondere steckbar verbindbar ist, wobei das Identifikationselement in das Verbindungsglied integriert ist. Das Verbindungsglied kann beispielsweise einen Verbindungszapfen aufweisen, der in eine komplementär ausgestaltete Verbindungsaufnahme der Spritzpistole eingesteckt werden kann, und das Identifikationselement kann in den Verbindungszapfen integriert sein. Das Identifikationselement kann beispielsweise in Form eines Transponders ausgestaltet sein, und eine dem Identifikationselement zugeordnete Erfassungseinheit der Spritzpistole kann beispielsweise ein dem Transponder zugeordnetes Lesegerät aufweisen, das der den Verbindungszapfen aufnehmenden Verbindungsaufnahme der Spritzpistole benachbart angeordnet ist. Beispielsweise kann das Lesegerät in eine Wand der Verbindungsaufnahme integriert sein. Über eine elektrische Verbindungsleitung kann das Lesegerät mit einer Elektroeinrichtung der Spritzpistole verbunden sein, wobei die Elektroeinrichtung eine Energieversorgungseinheit aufweist, mit der das Lesegerät mit elektrischer Energie versorgt werden kann. Die Energieversorgungseinheit kann beispielsweise als Batterie ausgebildet sein, insbesondere als wiederaufladbare Batterie.It is particularly advantageous if the discharge unit has a mechanical connecting element which can be mechanically connected, in particular plugged in, by means of a spray gun, the identification element being integrated in the connecting element. The connecting member can, for example, have a connecting pin which can be inserted into a complementarily designed connecting receptacle of the spray gun, and the identification element can be integrated in the connecting pin. The identification element can be configured, for example, in the form of a transponder, and a detection unit of the spray gun assigned to the identification element can, for example, have a reader assigned to the transponder, which is arranged adjacent to the connection receptacle of the spray gun that receives the connecting pin. For example, the reading device can be integrated in a wall of the connection receptacle. The reading device can be connected to an electrical device of the spray gun via an electrical connecting line, the electrical device having an energy supply unit with which the reading device can be supplied with electrical energy. The energy supply unit can be designed, for example, as a battery, in particular as a rechargeable battery.

Zur Betätigung des Ventils 54 weist die Spritzpistole 14 einen Abzug 56 auf, der verschwenkbar an einem Handgriff 58 der Spritzpistole 14 angeordnet ist und vom Benutzer manuell betätigt werden kann, um das Ventil 54 zu öffnen und zu schließen.The spray gun 14 has a through-
Der Pistoleneinlass 50 steht über eine Druckleitung, im dargestellten Ausführungsbeispiel über einen Druckschlauch 60, mit dem Pumpenauslass 38 in Strömungsverbindung, so dass der Spritzpistole 14 Reinigungsflüssigkeit, die vom Hochdruckreinigungsgerät 12 unter Druck gesetzt wurde, zugeführt werden kann.The
An den Pistolenauslass 52 der Spritzpistole 14 kann nach Wahl des Benutzers eine der Austragseinheiten 16, 18, 20, 22, 24 und 26 angeschlossen werden. Welche Austragseinheit zum Einsatz kommt, hängt davon ab, welche Art von Fläche mittels des Hochdruckreinigungssystems 10 gereinigt werden soll. Über die Spritzpistole 14 können die Austragseinheiten 16, 18, 20, 22, 24 und 26 mit dem Pumpenauslass 38 in Fluidverbindung gebracht werden, so dass über die jeweils an die Spritzpistole 14 angeschlossene Austragseinheit unter Druck stehende Flüssigkeit auf eine zu reinigende Fläche gerichtet werden kann. Die Abgabe von Reinigungsflüssigkeit kann vom Benutzer mittels des Ventils 54 gesteuert werden.One of the
Zur Herstellung einer mechanischen Verbindung und einer Fluidverbindung mit der Spritzpistole 14 weisen die Austragseinheiten 16, 18, 20, 22, 24, 26 jeweils ein Verbindungsglied 62 auf mit einem Verbindungszapfen 64 und mit zwei Bajonettflügeln 66, 68. Das Verbindungsglied 62 wirkt mit einem komplementär ausgestalteten Verbindungsglied 70 der Spritzpistole 14 formschlüssig zusammen. Das Verbindungsglied 70 weist hierzu eine Verbindungsaufnahme 72 auf, in die der Verbindungszapfen 64 eingesetzt werden kann. Außerdem weist das Verbindungsglied 70 Bajonettausnehmungen auf, die mit den Bajonettflügeln 66, 68 in einer Schließstellung zusammenwirken. Derartige Bajonettausnehmungen sind dem Fachmann an sich bekannt und daher zur Erzielung einer besseren Übersicht in der Zeichnung nicht dargestellt.To establish a mechanical connection and a fluid connection with the spray gun 14, the
Die Austragseinheit 16 weist eine Hochdruck-Flachstrahldüse 74 auf, die dem Fachmann an sich bekannt ist und daher in der Zeichnung nur schematisch dargestellt ist. Mittels der Hochdruck-Flachstrahldüse 74 kann ein fächerförmiger Hochdruckstrahl abgegeben werden.The
Die Austragseinheit 18 weist eine Hochdruck-Rotordüse 76 auf, mit der ein auf einem Kegelmantel umlaufender Punktstrahl erzeugt werden kann. Derartige Hochdruck-Rotordüsen 76 sind dem Fachmann an sich bekannt und bedürfen daher vorliegend ebenfalls keiner näheren Erläuterung.The
Die Austragseinheit 20 umfasst eine erste Waschbürste 78, und die Austragseinheit 22 umfasst eine zweite Waschbürste 80. Die beiden Waschbürsten 78 und 80 unterscheiden sich hinsichtlich ihrer Form und Funktion voneinander.The
Die Austragseinheit 24 umfasst eine Schaumdüse 82 und einen Austragsbehälter 84, in dem eine schaumbildende Chemikalie bevorratet werden kann. Die schaumbildende Chemikalie kann der über die Spritzpistole 14 vom Hochdruckreinigungsgerät 12 bereitgestellten Reinigungsflüssigkeit zugesetzt werden, so dass ein Reinigungsmittelschaum abgegeben werden kann.The
Die Austragseinheit 26 ist in den
Je nach Art und Beschaffenheit der zu reinigenden Fläche und auch je nach Art der gewünschten Reinigung, beispielsweise Grobreinigung, abrasive Reinigung, Schaumreinigung, Bürstenreinigung, kann der Benutzer wahlweise eine der Austragseinheiten 16, 18, 20, 22, 24, 26 an die Spritzpistole 14 anschließen und die zu reinigende Fläche mit Reinigungsflüssigkeit beaufschlagen, wobei der Reinigungsflüssigkeit gegebenenfalls eine Reinigungschemikalie aus dem Behälter 42 oder eine schaumbildende Chemikalie aus dem Austragsbehälter 84 beigemischt werden kann.Depending on the type and nature of the surface to be cleaned and also on the type of cleaning desired, for example rough cleaning, abrasive cleaning, foam cleaning, brush cleaning, the user can choose one of the
Selbstverständlich soll für jede der Austragseinheiten 16, 18, 20, 22, 24, 26 ein möglichst gutes Reinigungsergebnis erzielt werden und eine Beschädigung der zu reinigenden Fläche soll selbstverständlich vermieden werden.Of course, the best possible cleaning result should be achieved for each of the
Um mit den Austragseinheiten 16, 18, 20, 22, 24, 26 ein möglichst gutes Reinigungsergebnis zu erzielen, ist es erforderlich, mindestens einen Förderparameter des Hochdruckreinigungsgeräts 12 an die jeweils zum Einsatz kommende Austragseinheit anzupassen. Diese Anpassung erfolgt beim Hochdruckreinigungssystem 10 selbsttätig. Jede Austragseinheit 16, 18, 20, 22, 24, 26 weist hierzu ein Identifikationselement 100 auf, das den Typ der jeweiligen Austragseinheit 16, 18, 20, 22, 24, 26 charakterisiert und im dargestellten Ausführungsbeispiel als Transponder 102 ausgestaltet ist. Der Transponder 102 ist im dargestellten Ausführungsbeispiel in das Verbindungsglied 62 integriert, und zwar in den Verbindungszapfen 64, der in die Verbindungsaufnahme 72 der Spritzpistole 14 eingesetzt werden kann.In order to achieve the best possible cleaning result with the
Die Spritzpistole 14 weist eine dem Identifikationselement 100 zugeordnete Erfassungseinheit 104 auf, mit deren Hilfe der Typ der jeweils angeschlossenen Austragseinheit 16, 18, 20, 22, 24, 26 erfasst werden kann. Die Erfassungseinheit 104 ist im dargestellten Ausführungsbeispiel als Lesegerät 106 ausgestaltet, mit dem ein in
Das Lesegerät 106 steht über eine elektrische Verbindungsleitung 108 mit einer Elektroeinrichtung 110 der Spritzpistole 14 in elektrischer Verbindung. Über die elektrische Verbindungsleitung 108 kann ein den jeweils erfassten Typ der Austragseinheiten 16, 18, 20, 22, 24, 26 charakterisierendes Signal an die Elektroeinrichtung 110 übertragen werden. Die Elektroeinrichtung 110 weist eine Energieversorgungseinheit in Form einer Batterie 112 auf sowie ein kombiniertes Eingabe-Ausgabegerät in Form eines Touchscreens 114, mit dessen Hilfe dem Benutzer mindestens ein Förderparameter des Hochdruckreinigungsgeräts 12 angezeigt werden kann und der Benutzer mindestens einen Förderparameter des Hochdruckreinigungsgeräts 12 manuell ändern kann.The
Die Elektroeinrichtung 110 weist ein erstes Funkglied 116 auf und die Steuereinrichtung 46 weist ein zweites Funkglied 118 auf, so dass zwischen der Elektroeinrichtung 110 und der Steuereinrichtung 46 über die Funkglieder 116, 118 Signale drahtlos übertragen werden können. Dies gibt die Möglichkeit, ein den Typ der aktuell an die Spritzpistole 14 angeschlossenen Austragseinheit 16, 18, 20, 22, 24, 26 charakterisierendes Steuersignal von der Elektroeinrichtung 110 an die Steuereinrichtung 46 zu übertragen, und von der Steuereinrichtung 46 kann ein Förderparameter an die Elektroeinrichtung 110 übertragen werden, der dann am Touchscreen 114 angezeigt werden kann.The
Wird der Förderparameter vom Benutzer am Touchscreen 114 geändert, so kann auch der geänderte Förderparameter von der Elektroeinrichtung 110 an die Steuereinrichtung 46 übertragen werden.If the conveying parameter is changed by the user on the
Die Steuereinrichtung 46 passt zumindest einen Förderparameter des Hochdruckreinigungsgeräts 12 selbsttätig an die jeweils zum Einsatz kommende Austragseinheit 16, 18, 20, 22, 24, 26 an. Als Förderparameter kommen insbesondere der am Pumpenauslass 38 herrschende Druck der Reinigungsflüssigkeit, der Volumenstrom der den Pumpenauslass 38 durchströmenden Reinigungsflüssigkeit sowie die Dosierung der mittels der Beimischeinrichtung 44 der Reinigungsflüssigkeit beimischbaren Reinigungschemikalie zum Einsatz. Diese Förderparameter können zur Erzielung eines möglichst guten Reinigungsergebnisses an die jeweils zum Einsatz kommende Austragseinheit 16, 18, 20, 22, 24, 26 selbsttätig angepasst werden. Hierzu sind im dargestellten Ausführungsbeispiel im Speicherglied 103 der Transponder 102 der Austragseinheiten 16, 18, 20, 22, 24, 26 die jeweils optimalen Förderparameter für die jeweilige Austragseinheit hinterlegt, und bei Anschluss der jeweiligen Austragseinheit an die Spritzpistole 14 kann der im Speicherglied hinterlegte Förderparameter mittels des Lesegeräts 106 ausgelesen werden. Ein entsprechendes Signal kann dann vom Lesegerät 106 über die Verbindungsleitung 108 an die Elektroeinrichtung 110 und von dieser über die Funkverbindung an die Steuereinrichtung 46 übertragen werden. Die Steuereinrichtung 46 steuert dann das Hochdruckreinigungsgerät 12 in der Weise, dass der jeweils ausgelesene Förderparameter bereitgestellt wird. Zu diesem Zweck weist das Hochdruckreinigungsgerät 12 einen Drucksensor 120 auf, mit dessen Hilfe der am Pumpenauslass 38 herrschende Druck der Reinigungsflüssigkeit erfasst werden kann, und das Hochdruckreinigungsgerät 12 umfasst einen Volumenstromsensor 122, mit dessen Hilfe der Volumenstrom der den Pumpenauslass 38 durchströmenden Reinigungsflüssigkeit erfasst werden kann. Darüber hinaus weist das Hochdruckreinigungsgerät 12 einen Konzentrationssensor 124 auf, mit dessen Hilfe die Konzentration der der Reinigungsflüssigkeit gegebenenfalls mittels der Beimischeinrichtung 44 beigemischten Reinigungschemikalie erfasst werden kann. Der Drucksensor 120 steht ebenso wie der Volumenstromsensor 122 und der Konzentrationssensor 124 mit der Steuereinrichtung 46 in elektrischer Verbindung, und die Steuereinrichtung steuert die Pumpe 34 sowie die Beimischeinrichtung 44 dergestalt, dass die von der Erfassungseinheit 104 bereitgestellten Förderparameter, die zur Erzielung eines möglichst guten Reinigungsergebnisses an die jeweils zum Einsatz kommende Austragseinheit 16, 18, 20, 22, 24, 26 angepasst sind, vom Hochdruckreinigungsgerät 12 bereitgestellt werden.The
Der Betrieb des Hochdruckreinigungssystems 10 gestaltet sich somit für den Benutzer sehr einfach, wobei je nach zu lösender Reinigungsaufgabe unterschiedliche Austragseinheiten 16, 18, 20, 22, 24, 26 zum Einsatz kommen können und die Förderparameter des Hochdruckreinigungsgeräts 12 selbsttätig an die jeweils zum Einsatz kommende Austragseinheit angepasst werden, ohne dass der Benutzer hierzu aufwendige Einstellungen am Hochdruckreinigungsgerät 12 oder an der Spritzpistole 14 vornehmen muss. Trotz der selbsttätigen Anpassung der Förderparameter an die jeweils zum Einsatz kommende Austragseinheit hat der Benutzer die Möglichkeit, die Förderparameter am Touchscreen 114 der Spritzpistole 14 bei Bedarf zu ändern.The operation of the high-
