Definitions

  • the invention relates to a cooling air guide and discharge system for electromotive mouthpieces for floor care devices, which have a separate cooling air duct of the electric motor and an independent working air duct.
  • Cooling air guidance and deflection systems of this type are known in that cool ambient air is drawn in through separate air inlet slots, then guided past the components to be cooled and released again into the ambient air from a separate outlet slot.
  • the dirt generated by the device e.g. Coal dust
  • led to the outside via the cooling air so that this cooling air is heavily loaded with fine dust, which in turn has to be separated by means of large-area fine filters; or the ultra-fine filter must be replaced during the life of the device.
  • the object of the invention is now to create a fine dust removal which avoids the need for additional technical means for separation, while avoiding the aforementioned disadvantages.
  • the aforementioned upstream additional device (1) is connected to the vacuum cleaner (2) via the plug connection (15) according to FIG. 1.
  • the dust-laden working air (L) is led from the floor (4) into the filter system (5) dedicated to the vacuum cleaner (2).
  • the cooling air (11) is conveyed through the opening (7) in the dirt-free area (13) past the motor (6) through the negative pressure of the working air in the suction area (8) into the air duct (3). All fine dust particles emitted by the auxiliary device (1), including those from coal dust abrasion, are transferred from the electric motor (6) via the outlet openings (9) into the filter system (5) of the vacuum cleaner (2) transported and deposited there, so that no additional filter devices for the cooling air (11) of the floor care device (12) are necessary.
  • the outlet openings (9) are arranged in such a way that the fine dust particles are fed directly to the suction area (8) and thus to the dirt suction opening (14) and entrained with the working air (L).
