Definitions

  • the invention relates to a vacuum cleaner with a filter, in particular with a vacuum cleaner exhaust filter in a Ab povertystromkanal a suction blower included by the vacuum cleaner.
  • Vacuum cleaners in particular electric vacuum cleaners in a version as domestic vacuum cleaners, work almost exclusively with multi-stage particle filters. So are usually before a vacuum cleaner fan a pre-filter - preferably designed as a dust bag - and behind an exhaust filter (vacuum cleaner exhaust filter) for the removal of fine dust that still passes the bag provided. The latter takes z. B. still the abrasion of carbon brushes or the like of the drive motor of the fan. Both filter stages must be replaced as consumables by the user of the vacuum cleaner. A user must be reliably and conveniently signaled when the bag or the exhaust filter must be changed as a result of reaching an upper limit for a filling or saturation. For the dust bag sensors are usually used, which operate on the differential pressure principle.
  • the exhaust filter is known to use an operating time of the filter as a criterion for a required replacement.
  • a time counter is considered, which is reset manually after inserting the exhaust filter by the user and the expiration of a fixed operating time signals the necessary change of the filter.
  • the algorithm for this and necessary operating and display elements are implemented in a vacuum cleaner control or part of the vacuum cleaner control.
  • the DE 102 29 796 describes a filter with a temperature-dependent integrating consumption indicator.
  • the color of the indicator changes depending on the temperature always when the vacuum cleaner is operated for a long time.
  • the DE 602 05753 T2 describes time-dependent consumption indicators that must be activated by the user by opening a fluid store. A colored indicator liquid diffuses into an absorbent material in the consumption indicator, which then discolors over time and thus represents a measure of the useful life.
  • the operating time as a criterion for a required filter change does not take into account or not yet optimally an actual load situation of the filter, because the pure, linear time sequence is not able to represent the actual and over time varying usage behavior.
  • An object of the present invention is accordingly to provide a vacuum cleaner with means for generating a consumption or saturation-compatible filter change signal.
  • a vacuum cleaner with a filter in particular as a vacuum cleaner exhaust filter in a Abluftstromkanal a vacuum cleaner suction filter acting, at least one electrically variably controllable light emitting means provided with a beam region comprising an optically sensitive filter change indicator mounted in or on the vacuum cleaner filter.
  • the electrically variably controllable light source which detects an optically sensitive filter change indicator of the filter with its beam area, a consumption and thus saturation-compliant irradiation of the filter change indicator can be effected by the light source.
  • a per se known optically sensitive filter change indicator, the z. B. ambient light is independent of an actual use of the vacuum cleaner and the same regardless of the operating state of the vacuum cleaner on the ambient light
  • a reaction of the optically sensitive filter change indicator is provided at least or exclusively on the variably controllable light source.
  • the variably controllable lighting means is only active when the vacuum cleaner is in operation, so that a reaction of the optically sensitive filter change indicator outside the operating phases of the vacuum cleaner is excluded or at least reduced.
  • the reaction of the optically sensitive filter change indicator e.g. B. its discoloration or decolorization, is a saturation-compatible filter change signal.
  • a light-emitting diode emitting in the ultraviolet range is provided as the light-emitting means, so that a basically UV-sensitive filter change indicator can be used as the optically sensitive filter change indicator.
  • a controllable by a vacuum cleaner control of the vacuum cleaner power source is provided, from which the or each light source is fed for electrically variable control.
  • the control of the power source by the vacuum cleaner control is carried out depending on the set or adjustable power level of the vacuum cleaner.
  • the irradiation of the optically sensitive filter change indicator takes place not only during the operating phases of the vacuum cleaner, but also during these operating phases depending on the power level of the vacuum cleaner used.
  • the power level of the vacuum cleaner determines the power with which the suction fan of the vacuum cleaner is operated, this power level is proportional to an amount of particles or the like, which are supplied in the exhaust duct of the suction fan to the attached vacuum cleaner exhaust filter. With this proportionality results in a proportional dependence of an increasing saturation level of the vacuum cleaner exhaust filter of the power level.
  • the vacuum cleaner comprises a control window enabling optical control of the filter change indicator and designed as a UV filter
  • the condition of the filter change indicator can be checked without the need to open the vacuum cleaner or even remove the filter.
  • the control window is designed as a UV filter and the filter change indicator is a UV-sensitive filter change indicator, it is ensured that there is no entry of a light energy that falsifies the state of the filter change indicator via the control window.
  • a UV-sensitive filter change indicator it reacts only or essentially only to UV light, which is filtered out of the ambient light by the UV-filtered control window, so that the filter change indicator remains visible through the control window without the necessary illumination of the filter change indicator its condition falsifies.
  • the vacuum cleaner may be equipped with a sensor for evaluating a change in at least one optical property of the filter change indicator. This eliminates the need for the user to periodically check the filter change indicator, and this check can instead be done automatically by the sensor. In a still existing control window for optical control of the filter change indicator the user has the opportunity to convince himself of the further usability of the vacuum cleaner exhaust filter and / or to monitor the automatic inspection of the filter change indicator.
  • a sensor for evaluating a change in at least one optical property of the filter change indicator is an electro-optical system with a beam source and a photodiode or a phototransistor into consideration.
  • the photodiode or the phototransistor is able to generate an electrical signal, which is dependent on a detected amount of light in a suitable, known per se circuitry.
  • the photodiode or the phototransistor are oriented so as to detect the at least one optical property of the filter change indicator so that the filter change indicator lies in its or its detection range.
