Description

Die Erfindung betrifft einen Staubsauger mit Bedien- und Anzeigeelementen für die Bedienung des Staubsaugers und die Anzeige von Informationen.The invention relates to a vacuum cleaner with controls and indicators for the operation of the vacuum cleaner and the display of information.

Üblicherweise sind Staubsauger mit mechanischen Tasten oder Schaltern versehen für die Bedienung des Staubsaugers. Außerdem können Anzeigeelemente wie Displays für die Anzeige der Staubsaugerleistung oder den Füllstand des Staubsaugerbeutels vorgesehen sein. Bei der Gestaltung des Designs eines Staubsaugers muss häufig ein Kompromiss zwischen der Handhabung und dem Bedienkomfort sowie der Gestaltung der Oberflächen und der Anzeige- und Bedienelemente getroffen werden. Zudem werden einige der Bedienelemente nicht von Hand bedient, sondern sind als Tritttasten ausgebildet, die häufig eher schwierig zu bedienen sind. Die Anzeigeelemente für die Staubsaugerleistung, einen erforderlichen Filterwechsel oder mögliche Störungen geben oft nur Basisinformationen wieder und sind zudem sehr klein ausgebildet, so dass die Information schlecht sichtbar ist.Usually vacuum cleaners are provided with mechanical buttons or switches for the operation of the vacuum cleaner. In addition, display elements such as displays for the display of the vacuum cleaner performance or the level of the vacuum cleaner bag may be provided. When designing the design of a vacuum cleaner, a compromise must often be made between handling and ease of use, as well as the design of the surfaces and the display and controls. In addition, some of the controls are not operated by hand, but are designed as kick buttons, which are often rather difficult to use. The display elements for the vacuum cleaner performance, a required filter change or possible disturbances often only give basic information and are also very small, so that the information is difficult to see.

Darüber hinaus sind mechanische Bedienelemente und elektronische Anzeigeelemente kostenintensiv und können auch während des Einsatzes eines Staubsaugers auch beschädigt werden. Außerdem benötigen diese Bedien- und Anzeigelemente einen gewissen Bauraum im Staubsaugerinnenraum, was sich negativ auf die Baugröße des Staubsaugers auswirkt.In addition, mechanical controls and electronic display elements are expensive and can also be damaged during use of a vacuum cleaner. In addition, these control and display elements require a certain amount of space in the vacuum cleaner interior, which has a negative effect on the size of the vacuum cleaner.

Die DE 199 18 072 A1 zeigt und beschreibt eine Prozesssteuerung mit Bedien- und Anzeigeelementen für die Bedienung des Prozesses und die Anzeige von Informationen, aufweisend eine Projektionseinheit zur Projektion der Bedien- und Anzeigeelement auf einer Projektionsfläche, eine Lichtquelle für Strahlung und eine Kamera zur Aufnahme von reflektierten Strahlen der Lichtquelle zur Erkennung einer Bedienung der Bedienelemente auf der Projektionsfläche.The DE 199 18 072 A1 shows and describes a process control with control and display elements for the operation of the process and the display of information, comprising a projection unit for projection of the control and display element on a projection screen, a light source for radiation and a camera for receiving reflected beams of the light source Detection of operation of the controls on the screen.

Aus der DE 195 25 894 A1 ist ein Staubsauger mit einer Projektionseinheit bekannt. In der DE 10 2011 050 357 A1 ist ein selbstständig verfahrbares Reinigungsgerät mit einer Kamera zur Erfassung von Bewegungsmustern eines Benutzers offenbart. Die EP 2 422 676 A1 offenbart einen Staubsauger gemäß dem Oberbegriff des Anspruchs 1. Insbesondere einen Staubsauger mit Bedien- und Anzeigeelementen , wobei durch eine Beleuchtungseinrichtung Licht auf eine Projektionsfläche projiziert wird. Der Erfindung stellt sich somit das Problem, die Bedien- und Anzeigeelemente zu vereinfachen, dabei die Bedienung des Staubsaugers zu erleichtern und eine bessere Anzeige von Informationen wie z.B. der Füllstand des Filters und die Saugleistung zu ermöglichen.From the DE 195 25 894 A1 is a vacuum cleaner with a projection unit known. In the DE 10 2011 050 357 A1 discloses a self-propelled cleaning device with a camera for detecting movement patterns of a user. The EP 2 422 676 A1 discloses a vacuum cleaner according to the preamble of claim 1. In particular, a vacuum cleaner with control and display elements, wherein light is projected onto a projection surface by a lighting device. The invention thus raises the problem of simplifying the operating and display elements, thereby facilitating the operation of the vacuum cleaner and to allow a better display of information such as the level of the filter and the suction power.

Erfindungsgemäß wird dieses Problem durch einen Staubsauger mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.According to the invention this problem is solved by a vacuum cleaner with the features of claim 1. Advantageous embodiments and modifications of the invention will become apparent from the dependent claims.

Ein erfindungsgemäßer Staubsauger weist eine Projektionseinheit zur Projektion der Bedien- und Anzeigeelemente auf eine Projektionsfläche auf, eine Lichtquelle für Strahlung im nichtsichtbaren Bereich und eine Kamera zur Aufnahme von reflektierten Strahlen der Lichtquelle zur Erkennung einer Bedienung der Bedienelemente auf der Projektionsfläche.A vacuum cleaner according to the invention has a projection unit for projecting the operating and display elements onto a projection surface, a light source for radiation in the non-visible region and a camera for receiving reflected rays of the light source for detecting an operation of the control elements on the projection surface.

Durch die Verwendung einer Projektionseinheit, die ein Bild auf eine Projektionsfläche projiziert, ist eine flexible Gestaltung von Bedien- und Anzeigeelementen ermöglicht. Durch einen Detektor können die Bediengesten einer Bedienperson auf der Projektionsfläche detektiert werden, wodurch eine einfache Bedienung der virtuellen Projektionsfläche ermöglicht ist.By using a projection unit that projects an image onto a projection screen, a flexible design of operating and display elements is made possible. By a detector, the operating gestures of an operator can be detected on the projection surface, whereby a simple operation of the virtual projection screen is made possible.

Unterhalb oder neben der Projektionseinheit befindet sich eine Lichtquelle im nichtsichtbaren Bereich, insbesondere im Infrarotbereich, sowie eine Kamera zur Aufnahme der reflektierten Strahlen von einem Gestenobjekt wie einem Finger auf den projizierten Bedienelementen wie den Tasten einer Tastatur. Aus der Reflexion des Lichtstrahls wird der Ort des Gestenobjekts auf dem Bedienelement und somit die gewünschte Funktion berechnet. Insbesondere können auch Wischbewegungen erkannt werden, wie sie beispielsweise aus der Bedienung von Smartphones bekannt sind.Below or next to the projection unit is a light source in the non-visible area, especially in the infrared range, as well as a camera for receiving the reflected rays from a gesture object such as a finger on the projected controls such as the keys of a keyboard. From the reflection of the light beam, the location of the gesture object on the control element and thus the desired function is calculated. In particular, wiping movements can be detected, as they are known for example from the operation of smartphones.

Die erfindungsgemäße Lösung hat insgesamt den Vorteil, dass sie einen geringen Bauraum benötigt, aus einfachen optoelektronischen Komponenten besteht und kostengünstig ist. Sie eröffnet neue Designmöglichkeiten für die Gestaltung eines Staubsaugers.The solution according to the invention has the overall advantage that it requires a small space, consists of simple optoelectronic components and is inexpensive. It opens up new design possibilities for the design of a vacuum cleaner.

Insbesondere kann die Projektionseinheit einen Laser oder eine oder mehrere LEDs (Light Emitting Diodes) umfassen, mit dem/denen z.B. ein Bedienelement auf einer Projektionsfläche projiziert werden kann. Insbesondere durch einen Laser kann eine stabile und verzerrungsfreie Projektion erreicht werden, wobei der Laser selbst nur einen geringen Bauraum benötigt.In particular, the projection unit may comprise a laser or one or more LEDs (Light Emitting Diodes) with which e.g. a control on a projection screen can be projected. In particular, by a laser, a stable and distortion-free projection can be achieved, the laser itself requires only a small amount of space.

Vorteilhafterweise ist die Projektionseinheit im oberen Handgriff des Staubrohrs des Staubsaugers untergebracht. Insbesondere bei einer Laserprojektion ist es möglich, einen von der Senkrechten abweichenden Projektionswinkel zu wählen, ohne dass es zu Verzerrungen in der Darstellung kommt.Advantageously, the projection unit is housed in the upper handle of the dust tube of the vacuum cleaner. In particular, in the case of a laser projection, it is possible to select a projection angle which deviates from the vertical, without distorting the representation.

In Fig. 1 ist ein Staubsauger 1 mit einer Projektionseinheit 2 an der Rückseite 3 des Staubsaugers 1 dargestellt. Mittels eines Projektionslasers oder von LEDs erfolgt eine Projektion auf eine Projektionsfläche 4, die hier mit strichlinierten Linien als Strahlungskegel dargestellt ist. Auf der Projektionsfläche 4 kann das Bild von Bedienelementen oder von Anzeigeelementen oder von beliebig anderen Informationen dargestellt werden. Eine in der Projektionseinheit 2 oder separat davon untergebrachte Lichtquelle 5, vorzugsweise im Infrarotbereich, und eine hier nicht näher dargestellte elektronische Kamera detektieren eine Gestenbewegung einer Bedienperson innerhalb der Projektionsfläche 4. In einer hier nicht gezeigten Steuereinheit können dann die Gesten der Bedienperson in Steuersignale umgesetzt werden. Bei den Gesten kann es sich auch um Wischbewegungen, wie sie für die Bedienung von Smartphones bekannt sind, handeln.In Fig. 1 a vacuum cleaner 1 is shown with a projection unit 2 on the back 3 of the vacuum cleaner 1. By means of a projection laser or LEDs, a projection onto a projection surface 4 takes place, which is shown here with dashed lines as a radiation cone. On the projection surface 4, the image of controls or display elements or any other information can be displayed. A light source 5 accommodated in the projection unit 2 or separately thereof, preferably in the infrared range, and an electronic camera, not shown here, detect a gesture movement of an operator within the projection surface 4. In a control unit not shown here, the operator's gestures can then be converted into control signals , The gestures may also be swiping, as they are known for the operation of smartphones act.

Die elektronische Kamera und die Lichtquelle 5 zeichnen sich gleichfalls durch einen Erfassungs- bzw. Ausleuchtungskegel aus, wobei der Öffnungswinkel jeweils so gewählt ist, dass er zumindest die Fläche des projizierten Bildes 4 erfassen kann.The electronic camera and the light source 5 are likewise distinguished by a detection or illumination cone, wherein the aperture angle is in each case selected such that it can capture at least the area of the projected image 4.

Insbesondere bei Verwendung eines Lasers bei der Projektionseinheit 2 können beliebige Flächen als Projektionsflächen 4 genutzt werden, da die üblicherweise erforderliche Anordnung des Projektors orthogonal zur Projektionsfläche nicht erforderlich ist. Dies eröffnet neue gestalterische Freiheiten für das Design eines Staubsaugers. Es kann auf Bedien- und Anzeigeelemente innerhalb der Oberfläche eines Staubsaugers gänzlich verzichtet werden, da der Boden selbst die Projektionsfläche bilden kann. Die Projektion kann dabei hinter, neben, vor oder auf dem Staubsauger erfolgen.In particular when using a laser in the projection unit 2, any surfaces can be used as projection surfaces 4, since the usually required arrangement of the projector orthogonal to the projection surface is not required. This opens up new creative freedom for the design of a vacuum cleaner. It can be completely dispensed with operating and display elements within the surface of a vacuum cleaner, since the floor itself can form the projection surface. The projection can be done behind, beside, in front of or on the vacuum cleaner.

Allgemeine Projektionsinhalte beziehen sich auf den Betriebszustand des Staubsaugers. Es ist eine Anzeige der Leistung und/oder von Bedienelementen zur Leistungsverstellung möglich. Besonders vorteilhaft ist eine Empfehlung, welche Bodenbeläge in welcher Leistungsstufe gesaugt werden sollen. Des Weiteren kann auch eine Automatik-Stufe angezeigt werden.General projection contents refer to the operating condition of the vacuum cleaner. It is possible to display the power and / or power adjustment controls. It is particularly advantageous to recommend which floor coverings should be vacuumed in which capacity level. Furthermore, an automatic level can also be displayed.

Weiter kann eine Filterwechselanzeige erfolgen, wobei hier zusätzlich Hinweise zur Lage der Öffnungstaste für den Staubraum oder auch ein Filterwechselvideo gezeigt werden können. Auch eine Anzeige von Störungen und Fehlern sowie eine Anzeige der Kundendiensttelefonnummer ist möglich.Further, a filter change display can be done, in which case additional information on the position of the opening button for the dust chamber or a filter change video can be shown. It is also possible to display faults and errors and to display the customer service telephone number.

Des Weiteren kann eine Bedienungsanleitung angezeigt werden oder es können Tipps zur Pflege von Bodenbelägen, Hinweise für nachkaufbares Zubehör sowie eine Übersicht über technische Daten des Staubsaugers angezeigt werden. Außerdem kann die Projektionseinheit 2 zur Ausleuchtung einer zu reinigenden Bodenfläche beispielsweise im Bereich der Saugdüsen eingesetzt werden.Furthermore, a user manual can be displayed or tips for the care of floor coverings, hints for purchasable accessories as well as an overview of technical data of the vacuum cleaner can be displayed. In addition, the projection unit 2 can be used for illuminating a floor surface to be cleaned, for example in the region of the suction nozzles.

Eine vorteilhafte Ausführung ist dabei die Projektion aus einem Handgriff 6 eines Staubrohres 7 des Staubsaugers 1 heraus, wie dies in Fig. 2 dargestellt ist. Vorteilhafterweise befindet sich die Projektionseinheit 2 hinter dem vorderen Saugvorsatz 8, da hier eine optimale Bedienung während des Saugvorganges gegeben ist. Die Projektionsfläche 4 ist vorteilhaftweise der Boden selbst, so dass der Bedienperson bei dem Staubsaugen wichtige und interessante Zusatzinformationen angezeigt werden können.An advantageous embodiment is the projection of a handle 6 of a dust pipe 7 of the vacuum cleaner 1 out, as in Fig. 2 is shown. Advantageously, the projection unit 2 is located behind the front suction attachment 8, since optimal operation during the suction process is provided here. The projection surface 4 is advantageously the bottom itself, so that the operator can be displayed with the vacuuming important and interesting additional information.

Wie in der Fig. 3 veranschaulicht, besteht ein weiterer Vorteil der Unterbringung der Projektionseinheit 2 im Handgriff 6 des Saugrohres 7 darin, dass beim Abstellen des Saugrohres 7 an der Rückseite 3 des Staubsaugers 1 in einer Parkposition eine Projektion auf der Oberseite 9 des Staubsaugers 1 stattfinden kann. Insbesondere sind in dieser Position Informationen, die Erläuterungen zum Filterwechsel betreffen, von Interesse. So kann während des Saugens der Bedienperson über eine Projektion auf dem Boden mitgeteilt werden, dass ein Filterbeutelwechsel erforderlich ist. Dann kann die Bedienperson aufgefordert werden, für weitere Zusatzinformationen das Saugrohr 7 an der Rückseite 3 des Staubsaugers 1 zu parken. Parkt die Bedienperson nun nach Beendigung des Saugvorganges den Staubsauger 1, dann erscheint automatisch auf der Oberseite 9 des Staubsaugers 1 ein Hinweis, an welcher Stelle der Staubsauger 1 zu öffnen ist und wie der Filterbeutel zu wechseln ist. Auch Zusatzinformationen zum Nachkauf von Filterbeuteln, z.B. per Internetbestellung, oder die Vorteile, die Originalfilterbeutel bieten, können angezeigt werden. Auch ist eine Anpassung der Informationsinhalte an länderspezifische Erfordernisse leicht möglich.Like in the Fig. 3 illustrates a further advantage of housing the projection unit 2 in the handle 6 of the suction tube 7 is that when you turn off the suction tube 7 on the back 3 of the vacuum cleaner 1 in a parking position projection on the top 9 of the vacuum cleaner 1 can take place. In particular, information relating to the filter change is of interest in this position. Thus, during suction, the operator can be informed via a projection on the floor that a filter bag change is required. Then, the operator may be required to park the suction tube 7 on the back 3 of the vacuum cleaner 1 for further additional information. If the operator now parks the vacuum cleaner 1 after completion of the suction process, then automatically appears on the top 9 of the vacuum cleaner 1 an indication of where the vacuum cleaner 1 is to open and how to change the filter bag is. Also, additional information on the purchase of filter bags, eg by Internet ordering, or the benefits that original filter bags offer, can be displayed. An adaptation of the information content to country-specific requirements is also easily possible.

Weiter mögliche Informationen bei einer Projektion auf der Oberseite 9 des Staubsaugers 1 können den Staubraumdeckel, das Zubehörfach oder die Parkposition des Staubrohres betreffen. Oder es wird die Position von zu wechselnden Filtern oder Filterbeuteln angezeigt. Daneben sind weitere Zusatzinformationen zu Filtertypen, zur Nachbestellung oder zur Entsorgung etc. möglich. Eine Weiterentwicklung sieht vor, Filmsequenzen zur Veranschaulichung des Filterwechsels auf der Projektionsfläche abzuspielen.Further possible information in a projection on the top 9 of the vacuum cleaner 1 may concern the dust compartment cover, the accessory compartment or the parking position of the dust tube. Or the position of filters or filter bags to be changed is displayed. In addition, further additional information on filter types, reordering or disposal etc. is possible. A further development plans to play film sequences to illustrate the filter change on the projection screen.

Wie in Fig. 4 veranschaulicht, ist auch eine Projektion bei einem selbstfahrenden Staubsauger, nachfolgend als Roboterstaubsauger 10 bezeichnet, auf dessen Oberfläche 11 möglich. Bei dem Roboterstaubsauger 10 handelt es sich um einen technisch hochentwickelten Staubsaugertyp, der mit Hilfe von Sensoren selbsttätig über die zu saugende Bodenfläche navigiert. Dabei ist es denkbar, dass die gesamte Oberfläche 11 ausgeleuchtet wird oder nur ein Segment. Denkbar ist auch, die Projektionseinheit 2 drehbar zu gestalten, so dass abwechselnd verschiedene Segmente als Projektionsfläche 4 dienen.As in Fig. 4 is also a projection in a self-propelled vacuum cleaner, hereinafter referred to as robotic vacuum cleaner 10, on the surface 11 is possible. The robot vacuum cleaner 10 is a technically advanced type of vacuum cleaner, which automatically navigates with the aid of sensors over the floor surface to be suctioned. It is conceivable that the entire surface 11 is illuminated or only one segment. It is also conceivable to make the projection unit 2 rotatable, so that alternately different segments serve as the projection surface 4.

Eine Weiterentwicklung sieht eine automatische Schwenkung der Projektionsfläche 4 je nach der Gebrauchslage des Staubsaugers 1 vor. So ist in Fig. 5 die Position der Projektionsfläche 4 während des Saugvorgangs gezeigt. Die Projektionseinheit 2 befindet sich an der Rückseite 3 des Staubsaugers 1 und leuchtet den Boden innerhalb der Projektionsfläche 4 aus.A further development provides for automatic pivoting of the projection surface 4, depending on the position of use of the vacuum cleaner 1. So is in Fig. 5 the position of the projection surface 4 during the suction process shown. The projection unit 2 is located on the rear side 3 of the vacuum cleaner 1 and illuminates the floor within the projection surface 4.

In der in Fig. 6 dargestellten Parkposition hingegen wird eine kleinere Fläche ausgeleuchtet, da die Projektionseinheit 2 nun einen geringeren Abstand zum Boden einnimmt. Die Projektionseinheit 2 ist dabei derart ausgebildet, dass eine Fokussierung des gewünschten Projektionsbildes stets auf die gewünschte Projektionsfläche 4 erfolgt. Auch hier kann eine Weiterentwicklung vorsehen, die Projektionseinheit 2 selbst schwenkbar in den verschiedenen Raumrichtungen zu lagern, so dass unterschiedliche Projektionsflächen 4 ausgeleuchtet werden können.In the in Fig. 6 shown parking position, however, a smaller area is illuminated, since the projection unit 2 now occupies a smaller distance from the ground. The projection unit 2 is designed such that focusing of the desired projection image always takes place on the desired projection surface 4. Here too, a further development can provide for the projection unit 2 itself to be pivotably mounted in the different spatial directions, so that different projection surfaces 4 can be illuminated.

In Fig. 7 ist eine weitere Form einer Projektionsanzeige 2 dargestellt. Hier ist zusätzlich ein Projektionsschirm 12 vorgesehen, der am Handgriff 6 befestigt ist. Die Projektionseinheit 2 befindet sich gleichfalls am Handgriff 6 und beleuchtet den Projektionsschirm 12. Durch die Nähe zum Handgriff 6 ist eine einfache Bedienung über eine Gestensteuerung durch eine Bedienperson möglich. Die Bedienperson muss sich nicht zum Staubsauger 1 hinunter beugen, um diesen zu bedienen. Ferner können verschiedene Informationen von dem Projektionsschirm 12 gut abgelesen werden, da die Projektionsfläche 4 ausreichend groß ist und damit eine gute Lesbarkeit gegeben ist.In Fig. 7 is another form of a projection display 2 shown. Here, a projection screen 12 is additionally provided, which is attached to the handle 6. The projection unit 2 is also located on the handle 6 and illuminates the projection screen 12. The proximity to the handle 6 is a simple operation via a gesture control by an operator possible. The operator does not have to bend down to the vacuum cleaner 1, to serve this. Furthermore, various information from the projection screen 12 can be read well, since the projection surface 4 is sufficiently large and thus good readability is given.

Durch die Erfindung ist es somit insbesondere möglich, ein neues Gerätedesign zu schaffen, da die Bedien- und Anzeigeeinheit zusammengeführt werden können. Eine Projektion von Zusatzinformationen und Sonderfunktionen ist sehr leicht möglich. Des Weiteren ist eine Steuerung über Gesten wie z.B. Wischbewegungen ähnlich wie bei Smartphones denkbar, z.B. um die Leistung des Staubsaugers hoch oder herunter zu regeln. Damit können Bediengewohnheiten, wie sich zunehmend in anderen Bereichen etablieren, auch für den Gebrauch von Staubsaugern eingesetzt werden.The invention thus makes it possible, in particular, to create a new device design, since the operating and display unit can be brought together. A projection of additional information and special functions is very easy. Furthermore, a control over gestures such as wiping movements similar to smartphones is conceivable, for example, to regulate the performance of the vacuum cleaner up or down. Thus, operating habits, as increasingly established in other areas, can also be used for the use of vacuum cleaners.
