Problems solved by technology
The disadvantage of this arrangement is that the access opening is located on top and thus emits the generated noise towards the user
Furthermore, such a filter replacement indicator arranged in the housing cover of the vacuum cleaner cannot be seen clearly during normal vacuuming operation.
This can cause delays in changing the dust container, which results in unsatisfactory vacuuming

Embodiment Construction
[0037] In the following description of the two preferred embodiments of the invention, the same reference numerals designate identical or comparable components.
[0038] According to the vacuum cleaner 4 of the present invention is shown in figure 1 middle. From the dust suction device designed as a bottom nozzle 25, the dust is passed through a motor-fan-unit, through a suction pipe 15 with an adjustable length, a connecting piece 14 and a flexible suction hose 16. The guiding device 5 is sucked into the vacuum cleaner 4 li. The dust separation unit 6 in the housing 26 of the vacuum cleaner 4 separates the dust containing the suctioned air into a collection chamber 7 .
[0039] Figure 9 The function schematic diagram of the present invention is briefly shown. According to this principle, the filter change indicator 1 comprises a measured value register 2 and a signaling unit 3 . The filter change indicator 1 is controlled via the measured value collector 2 on the one ha...

The invention relates to a vacuum cleaner (4) having a filter replacement indicator (1), wherein the vacuum cleaner (4) comprises: a suction air guide (5), a dust separation unit (6) in a collection space (7) and a motor / blower unit (8) in a housing (26), and the filter replacement indicator (1) comprises: a data logger (2) and a signal unit (3), wherein the filter replacement indicator (1) can be controlled via the data logger (2) by a first parameter (9) outside of the vacuum cleaner (4), as well as by a second parameter (10) created by the motor / blower unit (8), wherein the second parameter (10), in connection with the first parameter (9), allows for a conclusion about a fault condition of the dust separation unit (6), wherein the data logger (2) can register a parameter present on or in the suction air guide (5) as a second parameter (10). The invention makes the assembly and function of a filter replacement indicator (1) on a handle (17) spaced away from a suction air guide (5) easier by means of simple design and cost-efficiency means. Furthermore, noise can be reduced and an intuitive fault indicator provided.
Description
technical field [0001] The invention relates to a vacuum cleaner with a filter replacement indicator, wherein the vacuum cleaner comprises: a suction guide, a dust separation unit in the collection chamber and a motor-fan-unit in the housing, while the filter The filter change indicator consists of: a measured value collector and a signal unit, wherein the filter change indicator can pass through the measured value collector, on the one hand by the first measured value outside the vacuum cleaner, on the other hand by the motor-fan- The second measured value generated by the unit is controlled, wherein the second measured value is combined with the first measured value to deduce the fault state of the dust separation unit. Background technique [0002] From the background art DE 39 41 039 A1 is known, for example, which describes an indicator device measured as a differential pressure for indicating the filling level of a filter bag arranged in a dust chamber of a vacuum clea...
