Definitions

  • the invention relates to a vacuum cleaner with a suction attachment and with a handle, wherein a handle and / or a suction tube and / or a suction unit is arranged to guide the suction attachment by means of the handle between them and with a lighting device for illuminating the working area in front of the suction attachment.
  • Vacuum cleaners with lighting equipment are well known.
  • a lamp is arranged in the suction attachment, see for example DE 103 53 456 A1 .
  • the lamp is activated by switching on the supply voltage of the vacuum cleaner and the associated switching on the suction fan and this remains for the entire suction operation.
  • this is not always necessary and therefore causes too high an energy consumption.
  • either a difficult-to-reach switch would have to be arranged on the suction attachment or an additional line would have to be laid in a more accessible area.
  • an illumination of the suction area is only possible if the vacuum cleaner is equipped with the corresponding suction unit.
  • a vacuum cleaner is known in which a lamp is inserted by means of a retaining clip on the suction pipe.
  • the lamp is powered by an exposed cable from the vacuum cleaner.
  • the DE 202 02 690 U1 discloses a vacuum cleaner, which is designed as a so-called table vacuum cleaner or vehicle vacuum cleaner.
  • a lighting device is arranged at a rear portion of the main housing. It is therefore unable to illuminate the work area in front of the suction attachment.
  • the power button of the lighting is arranged on a handle.
  • the JP 2007 267779 A shows a vacuum cleaner in which a light-emitting diode is arranged in a handle.
  • the handle also includes a battery and an operating device.
  • the light of the light emitting diode is coupled into a light guide, which is connected to a special light source Suction attachment is located.
  • the light emerging from the suction attachment illuminates the surface to be processed before placing the suction attachment.
  • the invention thus raises the problem of disclosing a vacuum cleaner of the type mentioned, in which the lighting device is constructed effectively and simply.
  • the illumination device is designed to illuminate the working area in front of the suction attachment.
  • the lighting devices known from the prior art are more adapted to illuminate the work area under the suction attachment or the suction attachment itself.
  • the user usually wants to see the area still to be edited in order to be able to estimate the necessary intensity.
  • the illumination device generates a cone of light emerging from the handle, which light beam is directed at the working area in front of the suction attachment when the suction attachment is placed on the surface to be processed. Due to the arrangement of the exit region of the light cone on the handle and the point of impact in front of the suction attachment, the illuminated area always moves in front of the suction attachment even during pivoting movements.
  • the illumination device is associated with an optical device which generates a light cone directed into the working area in front of the suction attachment.
  • the length of conventional suction tubes With the length of conventional suction tubes, misalignment of the light cone of one to two degrees already leads to unsatisfactory illumination, in which case the illuminated area is either too far in front of the suction attachment or the suction attachment itself is illuminated. Therefore, it is particularly advantageous if there are means which position both the light source and the optical device at an angle. An installation at a defined angle can be achieved in a simple manner if LEDs are used as the light source, in particular flat LED's in SMD construction, which are then soldered directly to a circuit board.
  • the light emitting diode and / or the optical device may have cooperating holding means, with which these two components can be positioned very accurately to each other.
  • the board and the optical device are fixed within a cover of the handle.
  • the receiving compartment and the operating device are arranged in the cover.
  • the cover can then be manufactured with all components, the "handle light" as a separate assembly and also tested. It can be provided by simply replacing the cover other handle variants, in which the cover then contains an adjustable secondary air opening or control buttons for switching on and off and power control of the suction fan.
  • a further board may be arranged, which carries the lighting device associated switching devices. Then it is particularly space-saving, if the board has a rectangular cutout, in which the receiving compartment is arranged.
  • the operating device is designed as a button. This will make the user aware of the "being turned on” lighting. It is particularly advantageous if the switch is associated with a switching device which keeps the lighting device turned on for a predetermined period after releasing the button.
  • a long-lasting and energy-saving lighting is achieved by the use of at least one light-emitting diode. It is advantageous if a driver circuit is used, with which the light-emitting diode is operated even with decreasing cell voltage of the battery or the accumulator with a constant current. As a result, a constant illuminance is achieved.
  • the claimed lighting device is preferably used in a vacuum cleaner, which is formed with a suction pipe arranged between the suction and the suction pipe.
  • FIG. 1 an operable vacuum cleaner 1 is shown. It has a base housing 2 to which a suction hose 3, a handle 4 and a suction tube 5, a suction attachment 6, here in the form of a simple floor nozzle, is connected.
  • the floor nozzle 6 dissolves the dirt located on the floor 7. This is then sucked together with the Air via the suction tube 5 and the suction hose 3 into the interior of the base housing 2 passed. There, the dirt is filtered out of the sucked air in a known manner.
  • the handle 4 serves to connect the suction tube 5 and the suction tube 3, on the other hand, it is provided for guiding and guiding the suction attachment 6 over the base 7 to be processed.
  • the handle 4 serves to connect the suction tube 5 and the suction tube 3, on the other hand, it is provided for guiding and guiding the suction attachment 6 over the base 7 to be processed.
  • a lighting device 8 is installed, with which the operator can illuminate a work area 9 in front of the suction attachment 6 with a cone of light 10 when using the vacuum cleaner 1 in the described arrangement.
  • the light cone 10 emerges from the illumination device 8 from the handle 4 and is exactly aligned so that it is directed into the working area 9 in front of the suction attachment 6 when it is placed on the surface to be machined 7.
  • FIGS. 2 to 4 show the entire handle 4 as a detail, being in FIG. 2 in perspective, in the FIG. 3 in a longitudinal section and in the FIG. 4 is shown in an exploded view.
  • the handle 4 consists essentially of a handle portion 41, a hose connection piece 42 and a pipe connection piece 43.
  • the hose connection piece 42 is rotatably mounted on the handle portion 41, he takes the suction hose 3 by means of a locking connection, not shown.
  • the pipe connection piece 43 is rotatably connected to the handle part 41. He also has a locking receptacle 44, by means of which the suction tube 5 can be attached to the handle.
  • the handle part 41 has an outer housing which consists of a handle upper part 45, a handle bottom part 46 and a cover 47.
  • a transparent disc 48 and a lid 49 are used, above the lid 49, a control knob 80 is arranged.
  • the lighting device 8 is arranged under the cover 47. In this case, all components that belong to the lighting device, held by the cover 47. Thus, this can be manufactured as a separately assembled and testable assembly.
  • the lamp itself is designed as a light emitting diode 81 and arranged on a circuit board 89.
  • On a further board 82 are a switching device 83 and a driver circuit 84, the function of which will be explained later.
  • the further board 82 has a rectangular cutout 85 into which a receiving drum 86 for three 1.5 volt AAA batteries or corresponding accumulators (both not shown) is inserted. These supply the power supply for the light-emitting diode 81 via the aforementioned circuits 83 and 84.
  • the drum 86 can be removed after removal of the cover 49, so that batteries or accumulators can be exchanged.
  • a lens 87 is arranged which focuses the emitted light and directs it through the transparent pane 48 to the position in front of the suction attachment 6.
  • the lens 87 is held by a lens holder 88.
  • the control knob 80 is as a button, d. H. designed as a non-latching pressure switch.
  • the switching device 83 ensures that after releasing the button 80, the light emitting diode 81 remains turned on for a predetermined period.
  • the operator thus has two options. A short keystroke starts a timer of the switching device 83. The light of the LED 81 then lights for about 15-30 seconds, depending on the size of the timer and then goes out slowly. A prolonged pressing the button results in a steady light, after releasing the button remains controlled by the switching device 83 by timer persistence with slow extinction.
  • the driver circuit 84 keeps the power supply to the LED 81 and thus its brightness constant until the cell voltage of the batteries has dropped to 0.9 volts per cell. By the driver circuit 84 is thus also ensured that when using batteries that usually have only a voltage of 1.2 volts, the light emitting diode 81 radiates with the same brightness as when using batteries. This results in a good utilization of energy sources.
  • FIGS. 5 and 6 the arrangement of the entire lighting device 8 is shown within the cover 47, in FIG. 5 in a perspective view from below, in FIG. 6 in a partial section. It can be seen that in the cover guides 90 to 93 are arranged, in which the circuit board 89 and the lens 87 are held defined. Further stabilization of the lens is achieved by further guides 94 and 95 which are arranged in the lens holder.
  • the lens receptacle has a recess 96 into which an extension 97 molded onto the lens (see also FIG FIG. 8 ) intervenes.
  • the perpendicular bisector of the generated light cone 10 a defined angle ⁇ (in the FIG. 6 shown as a change angle) to the suction tube 5 and occupy the working area 9 in front of the suction exactly illuminates.
  • the angle should be between 5 ° and 10 °, preferably about 7.5 °.
  • LED 81 and lens 87 are also further supported by the fact that these two components have cooperating holding means and thereby the lens can be attached to the LED, see FIGS. 7 and 8 .
  • the LED 81 is manufactured as a TopLED in SMD construction and thereby defined on the board 89 placeable.
  • the lens 87 has on its side facing the LED 81 a groove-shaped recess 98, with which it can be placed on the rectangular base body 99 of the LED 81. This connection can be made prior to inserting the board 89 and the lens 87 into the cover 47 and the mounting and screwing of the lens holder 88 and favors the defined assembly of said parts.
  • FIG. 7 also shows the electrical connection 100 of the two boards 82 and 89th
