Definitions

  • the invention relates first to a Staubzauger with arrangement of a filter, in particular superfine filter, in a vacuum cleaner with an electric motor having a suction side and a blast side, wherein in the case of the ultrafine filter on the blast side a receiving chamber for the superfine filter is provided, and the filter is a filter frame having.
  • An arrangement of the type in question is for example from the DE 202 07 256 U1 known.
  • Vacuum cleaners have in a known manner a Staubsarnmelgargar for filtering dust and dirt particles from the dirt-laden suction air stream. It is further known in this regard, the hereafter purified by coarse particles suction air flow before exiting into the environment by a Feinstfilter to lead to the retention of fines Such a fine filter is arranged on the blast side of the electric motor. In addition to the filtering out of the smallest dust particles still present in the blow-off air flow, such a microfilter also optionally serves to filter out carbon particles from the upstream electric motor. Since the recorded in the usual way in a plastic housing of the ultrafine filter paper is added over time with particles, it is also known to interchangeable absorb the particulate filter in the vacuum cleaner.
  • the operating life of a filter for a vacuum cleaner depends, among other things, on the degree of filling of the filter or on the degree of clogging of the filter material used. Such a filter state is via a pressure-dependent Greier recorded and displayed to the user. If a predefined differential or negative pressure value is exceeded or undershot, the respective filter must be changed.
  • a well-known vacuum cleaner is also in De 10229726 A1 described.

  • Such an operating hours counter proves to be particularly advantageous in connection with a superfine filter, since in this case the filling degree determination by means of pressure measurement proves to be unsuitable (inter alia, too costly).
  • such an operating hours counter can also be used in conjunction with a conventional dust filter bag or the like.
  • the filter frame may in this case be a plastic frame comprising the filter material, in particular in the case of a micro-filter.
  • the filter frame may be formed by a holding plate holding the dust filter bag in the corresponding receiving chamber.

When a predetermined time value is exceeded, the user is displayed the necessary filter change via an acoustic and / or visual signal. Preference is given in this regard Further, resetting the operating hours counter to a zero position can only be accomplished by employing a filter having a filter frame having a corresponding actuating tab.
  • the actuating tab is offset with the filter inserted in a non-actuated position. It is preferred in this regard that the actuating tab is pivoted in the non-actuating position lasting.
  • an arrangement is provided in which an already inserted into a corresponding receiving chamber Feinstfilter is detected by the permanently pivoted operating tab. Only one not yet used filter accordingly has an actuating tab which projects into the actuating position, that is to say into a position corresponding to the operating hours counter.
  • a switching element is further preferably provided, which is to be actuated only by a non-offset actuating tab.
  • the operating hours counter is not to be put into its zero position by a filter already used once. This is only possible by a new, provided with a non-offset actuating tab filter. Accordingly, it is ensured that the reset of the operating hours counter is achieved by a new, unused filter.
  • the switching element can act on an electric switch whose switching state is detected by an electronics or the like. About this electronics is the clocking of the operating hours counter and also its reset to the zero position. In addition, the electronics can also be used to acoustically and / or visually display the condition of the filter. In one embodiment, it is provided that the switching element moves the electric switch either in a switched or in a non-switched position at each passage of the unequipped operating tab.
  • the downstream electronics monitors the position of the electric switch.
  • the operating hours counter is reset with each switching movement of the electric switch from a switched position to a non-switched position and vice versa. Accordingly, the position change of the electric switch is detected via the downstream electronics, which leads to a reset of the operating hours counter in the zero position.
  • the operating hours counter continues to run, so according to a reinserting an already used and provided with a correspondingly in a non-actuation position permanently pivoted actuating tab filter.
  • the switching element can interact with removal of the filter as Ver GmbHsanschlag with the actuating tab. When inserting the filter into the receiving chamber, the non-offset actuating tab overflows the switching element.
