DETAILED DESCRIPTION OF THE DRAWINGS
[0026] Referred to in the drawings by reference numeral 1, a cleaning station according to the disclosure with a vacuum robot 2 is shown purely schematically. The illustration according to FIG. 1 shows a cleaning station 1 having a housing 4. This housing 4 has an electrical interface 5 which is designed to contact the vacuum robot 2 which has approached the cleaning station 1 for charging, i.e. a vacuum robot 2 that is interfaced with or is otherwise engaged with the cleaning station 1. The housing 4 also has a suction device 6 which serves to empty the vacuum robot 2. Furthermore, the housing 2 also has a status display 7 which is designed to display an operating status of the interface 5 and/or the suction device 6. The status display 7 comprises a projection apparatus 8 which is designed to project the operating status of the interface 5 and/or the suction device 6 onto the vacuum robot 2 which has approached and/or onto the floor surface 3 (FIG. 2) and/or onto a wall surface 9 (FIG. 2) surrounding or adjacent the cleaning station 1. In this way, sufficiently large display surfaces can be created by means of which the operating status of the cleaning station 1 can be displayed in a clear and easily visible way. FIG. 1 shows the preferred position of the projection apparatus 8 for projecting the operating status onto the vacuum robot 2 which has approached. Here, the projection apparatus 8 is arranged in the recessed part of the housing 4 for the vacuum robot 2. In this position, the top side 17 of the vacuum robot 2 can be used as a display surface by projecting the operating status when said vacuum robot has approached the cleaning station 1 for emptying and/or for charging.
[0027] FIG. 2 is a side view of the cleaning station 1 according to FIG. 1. This illustration shows further preferred positions for projection apparatuses 8 for projecting the operating status of the interface 5 and/or the suction device 6 onto a wall surface 9 surrounding the cleaning station 1. In the illustration shown here the cleaning station 1 is placed, as usual, on the floor surface 3 at a wall 9 in the living space. The operating status of the interface 5 and/or the suction device 6 can be simply projected on the wall 9 facing the rear side 15 by means of the status display 7 projection apparatus 8 arranged on the rear side 15 of the housing 4. Because wall paints usually have a fairly bright surface, the projected light can be reflected easily.
[0028] FIG. 3 shows a rear view of the cleaning station 1 according to FIGS. 1 and 2. It can be seen from this illustration that the projection apparatuses 8 are formed by a plurality of LED lights 10 arranged side by side on the housing 4. Here, an upper projection apparatus 8 is formed by a horizontal light strip, while in the lower region of the rear side 15 of the housing 4, a vertical light strip is provided as a projection apparatus 8 having a plurality of LED lights 10 arranged side by side. The LED lights 10 are advantageously designed to be activated in order to generate light color and/or light intensity and/or light frequency. Thus, by changing the light color and/or light intensity and/or light frequency, different operating states of the cleaning station 1 can be projected very vividly onto the wall surface 9 (FIG. 2) behind the cleaning station 1.
[0029] FIG. 4 shows an embodiment of the cleaning station 1 which has, as a projection apparatus 8, a light guide 11 on the housing 4. High illumination of the display surface formed on the wall surface 9 (FIG. 2) can be achieved via a light guide 11 having a small number of LED lights 10. In this way, the operating status of the interface 5 and/or the suction device 6 can be displayed particularly efficiently and clearly. The light guide 11 is illuminated by LED lights 10 arranged in the housing 4. Light guided by the light guide 11 is emitted by illumination of the light guide 11 for the projection of the operating status of the interface 5 and/or the suction device 6. The light guide 11 is advantageously laid in a U-shape along the rear side 15 of the housing 4. This U is flipped, e.g. upside down, in the embodiment shown. The U-shaped course on the rear side 15 of the housing 4 improves the illumination of the wall surface 9 (FIG. 2) behind the cleaning station 1. Thus, the operating status of the interface 5 and/or the suction device 6 can be particularly clearly shown by projection on the wall surface 9 facing the rear side 15 (FIG. 2). Since the U-shaped light guide 11 is illuminated by an LED light 10 arranged at each conductor end 16, only a small number of LED lights 10 are required to fully illuminate the wall surface 9 facing the rear side 15 (FIG. 2). The conductor ends 16 of the light guide 11 are preferably inclined inwardly so that light can be introduced into the interior of the cleaning station 1 by the LED lights 10. In this case, too, the LED lights 10 can be designed to be activated in order to generate light color and/or light intensity and/or light frequency. Thus, by changing the light color and/or light intensity and/or light frequency, different operating states of the cleaning station 1 can be projected very vividly onto the wall surface 9 (FIG. 2) behind the cleaning station 1. It is therefore possible to have a large amount of information about the operating status of the vacuum robot 2 and the cleaning station 1 in the field of view. The occurrence of faults or maintenance requirements can be displayed. For example, it is possible to indicate that the dust bag of the suction device 6 is full by the illumination/flashing of the light guide 11 in the color of a bag holding plate, or to indicate that the filter needs to be replaced by projecting the color of the filter of the suction device 6. As can be seen, the housing 4 has a receiving trough 12 in which the light guide 11 is laid. The receiving trough 12 is designed to be open in the emission direction 13 in order to project the operating status of the interface 5 and/or the suction device 6. The light guide 11 is securely arranged in the receiving trough 12 and the light emitted by the light guide 11 can simply be directed toward the wall surface 9 (FIG. 2), thereby preventing glare.
[0030] FIGS. 5 and 6 show detailed views of the light guide 11. These views show that the light guide 11 has a plurality of notches 14, the notches 14 being designed to refract the guided light and to emit it from the light guide 11 in order to project the operating status of the interface 5 and/or the suction device 6. By changing the size and number of notches 14 in each light guide portion, the amount of light emitted along the light guide 11 for projection can be influenced in a very simple way. In FIG. 5, small notches 14 emit a relatively small amount of light from the light guide 11 at relatively large spacings, while in FIG. 6 relatively large notches 14 are shown at relatively small spacings, thereby emitting a larger amount of light 11. Preferably, the upper region of the U-shaped light guide 11 (FIG. 4) is provided with relatively large notches 14 at relatively small spacings, while the lower region of the U-shaped light guide 11 (FIG. 4) is provided with relatively small notches 14 at relatively large spacings. In this way, uniform emission can be achieved on the light guide 11 by the LED lights 10 arranged at the lower conductor ends 16. The notches 14 are preferably arranged at regular intervals along an inner edge of the light guide 11. As the distance from the LED light 10 increases, the size of the notches 14 should increase. At the boundary surfaces of these notches 14 light exits the light guide 11 through partial transmission and is projected onto the wall surface 9 located therebehind (FIG. 2). The light is preferably diffusely reflected by the wall surface 9 (FIG. 2) and strikes the eye of an observer located in front of the cleaning station 1. In another advantageous embodiment, the contour of the light guide 11 projected onto the wall surface 9 (FIG. 2) approximates the outer contour of the cleaning station 11 projected onto the wall surface 9 (FIG. 2) so that the light output perceived by the observer is as uniform as possible around the cleaning station 11.
[0031] Of course, the disclosure is not limited to the illustrated exemplary embodiments. Other embodiments are possible without departing from the basic concept.
