Vacuum cleaner

#The present disclosure relates to the subject matter disclosed in international application number PCT/EP2009/003098 of Apr. 29, 2009 and German application number 10 2008 022 321.2 of Apr. 30, 2008, which are incorporated herein by reference in their entirety and for all purposes.

#The invention relates to a vacuum cleaner comprising a lower housing part, on which wheels are mounted for moving the vacuum cleaner along a floor surface, and which forms a dirt collection container with a suction inlet to which a suction hose is connectable, and an upper housing part which is mountable on the lower housing part and accommodates an electrically drivable suction unit, and an electric supply cable for connecting the suction unit to an electrical voltage source.

#A floor surface, for example, or a piece of furniture, in particular, upholstered furniture, can be vacuumed with such vacuum cleaners. The vacuum cleaner can be moved along the floor surface by the user. To this end, wheels are mounted on the lower housing part, for example, two running wheels and at least one steering wheel pivotable about a vertical pivot axis. The suction unit arranged in the upper housing part, which comprises an electric motor and a suction turbine, generates a negative pressure in the dirt collection container formed by the lower housing part, so that dirt particles can be sucked into the dirt collection container via the suction hose which can be connected to the suction inlet. An electric supply cable is used to supply the suction unit with electrical energy.

#The drawings show diagrammatically a vacuum cleaner 10 in accordance with the invention with a lower housing part 11 and an upper housing part 12 mountable on the lower housing part 11. The lower housing part 11 forms a dirt collection container 14 with a suction inlet 15, which is in the form of a pipe connection and to which a suction hose 17 can be connected. In the embodiment shown in FIG. 1, a telescopic suction pipe 18 is connected to the free end of the suction hose 17. The suction pipe 18 carries at its free end a floor nozzle 19 for vacuuming a floor surface.

#The upper housing part 12 accommodates in the usual way, which is, therefore, not shown in the drawings, a suction unit with a suction turbine which is driven by an electric motor. The dirt collection container 14 can be subjected to negative pressure in the usual way by the suction unit, so that dirt particles can be drawn into the dirt collection container 14 via the floor nozzle 19, the suction pipe 18 and the suction hose 17.

#For connection of the suction unit to an electrical voltage source, the vacuum cleaner 10 comprises an electric supply cable 21 which, for storage of the vacuum cleaner 10, can be placed in a cable receptacle 22 which, in the form of a channel 23, surrounds the upper housing part 12 in the circumferential direction. The channel 23 has an opening 25. This will be apparent from FIG. 3. Via the opening, an end portion of the supply cable 21 can be inserted into the interior of the upper housing part 12, so that the supply cable 21 can be connected to control electronics of the vacuum cleaner 10. A strain relief can be fixed in the area of the opening 25.
