Definitions

  • the present invention relates to a so-called vacuum cleaner turbo brush, so a vacuum cleaner mouthpiece with a driven by a turbine brush or bristle roller for a vacuum cleaner, in particular a vacuum cleaner in an embodiment as a vacuum cleaner, but also for so-called hand vacuum cleaner, wherein the turbo brush with a turbine (24 ) equipped in the secondary air flow and designed as a constant pressure turbine.
  • Turbo brushes are known per se and are used for example for cleaning carpets or the like and for sucking carpets with festgeandem dirt in carpet pile.
  • a vacuum cleaner mouthpiece with SaugrohranInstitut, sliding sole and rotating brush roller is described.
  • the brush roller is driven by a radially impinged turbine. Downstream of the turbine, a relatively narrow, movable nozzle is provided which concentrically directs the suction air or main air flow passing the nozzle to the impeller or turbine wheel.
  • the turbine is a so-called resistance rotor.
  • turbo brushes In addition to turbo brushes with turbines, which are driven by the suction air, turbo brushes are also known in which the turbines are driven as overpressure turbines in a secondary air flow with clean ambient air.
  • a disadvantage of the previous concepts is for a turbine in the main air flow especially a mostly reduced efficiency, which results from the fact that can not be used with the otherwise possible gaps between impeller and turbine housing due to the expected dirt particles in the air flow.
  • the blade distances must be made comparatively large so that dirt particles can pass through the impeller.
  • Known overpressure turbines which are operated in the secondary air flow with clean ambient air, require the lowest possible gap between impeller and turbine housing to achieve sufficient efficiency.
  • a significantly higher compared to the resistance rotor impeller speed typically factor four
  • a complex conversion gear for transmitting the drive power to the brush roller is required.
  • a turbine of the type mentioned is from the GB 2 393 383 A known. There is proposed as a possible embodiment, a radially impinged turbine, but also a Peltonrad.
  • An object of the invention is to provide a further embodiment of a turbo brush, in particular an embodiment of a turbo brush with improved efficiency of the turbine used in the turbo brush.
  • a vacuum cleaner turbo brush with the features of claim 1 or a vacuum cleaner with such a vacuum cleaner turbo brush. It is provided for the vacuum cleaner turbo brush that the turbine is arranged in the secondary air flow and designed as a constant pressure turbine.
  • the arrangement of the turbine in the secondary air duct and thus in the resulting secondary airflow during operation prevents dirt entry as it is unavoidable in an arrangement in the main air flow.
  • the ambient air as the working medium before and after the impeller has the same static pressure. To drive the impeller, therefore, only the converted kinetic energy, the dynamic pressure, the sucked in ambient air is used.
  • a constant-pressure turbine has a degree of reaction of zero, while overpressure turbines have a degree of reaction greater than zero.
  • a constant pressure turbine is due to the lack of pressure difference before and after the impeller mainly in the possibility of less accurate sealing between the blades of the impeller and the turbine housing. This simplifies the production and allows production of the individual components with less stringent tolerances. Furthermore, a speed level of a constant pressure turbine with the same power output is about one-third below the speed level of a positive pressure turbine. This results either in a lower noise during operation or a possibility for toyssyereinfachung over a positive pressure turbine, because less attention must be paid to noise-reducing measures or materials. This leads to a lighter and less expensive to manufacture turbine or a unit of turbine and a gearbox combined with it, because even for the gear initially results in the lower speed in a reduced noise. Finally, with the same mass flow and the same turbine diameter, a constant pressure turbine delivers twice as much power as a positive pressure turbine with a degree of reaction of 0.5.
  • the turbine is designed as an axial flowed impulse turbine. This allows simple conditions when fitting in a secondary air duct, through which the secondary air flow is sucked.
  • the turbine housing can also round with its round outer contour Section of the secondary air duct are fitted so that edge-free or at least largely edge-free transitions between the secondary air duct and the turbine housing and further between the turbine housing and the upstream adjoining part of the secondary air duct are possible.
  • the shaft housing acts as a turbulence-preventing or reducing guide element for the incoming ambient air and in the area of the turbine shaft in the region of a transition to the impeller Shroud of the turbine shaft and for receiving bearing elements for mounting the turbine shaft. If the shaft housing is widened in the region of the transition to the impeller to the entire diameter of the impeller and has openings for flow of the impeller, this part of the shaft housing also acts as a guide stage for the impeller.
  • baffle is part of the shaft housing, in particular integrally connected to the rest of the shaft housing, simple conditions for the production of the shaft housing and because of then possible edge-free transition favorable conditions for a laminar, turbulence-free or turbulenzenarme flow around the shaft housing and that of the Shrouding the turbine shaft via a guide element, which directs the incoming ambient air away from the arranged in the center of the secondary air duct turbine shaft and toward the blades of the impeller, to the Leitcut.
  • Embodiments of the invention are the subject of the dependent claims. Relationships used here point to the further development of the subject-matter of the main claim by the features of the respective sub-claim.
  • the vacuum cleaner turbo brush on a turbine downstream two-stage transmission in particular in one embodiment as a belt transmission, for driving the bristle roller.
  • the transmission allows a high speed of the bristle roller at a lower speed of the turbine than in a direct drive of the bristle roller.
  • the design-related, compared to an overpressure turbine lower speed of a constant pressure turbine can be compensated or more than compensated.
  • a version as a belt transmission allows at the resulting speeds in operation, a substantial avoidance of running noise.
  • the vacuum cleaner turbo brush has a transmission housing surrounding the transmission with a turbine shaft opening and a driven belt opening and means for combination with the shaft housing.
  • the transmission housing also encapsulates the transmission, so that in the secondary air flow or in the region of the secondary air flow, a significant proportion of the movable components, apart of course from the turbine wheel, are encapsulated, so that on the one hand dirt but on the other hand avoids turbulence and thus reducing the efficiency of the turbine reducing air turbulence or reduced.
  • journal of the impeller is delimited by a narrower parabolic arc at a lower side surface in the direction of rotation by a further parabolic arc and an upper lateral surface in the direction of rotation.
  • the turbine When in the vacuum cleaner turbo brush with a housing and a main air and secondary air duct formed therein, the turbine is arranged in the secondary air duct and the main air duct are arranged centrally in the housing and the secondary air duct laterally adjacent to the main air duct, a concentration of the suction power is ensured on the main air duct. Only part of the suction power leads to the intake of ambient air via the secondary air duct.
  • the lower shell or the lower shell with channel walls integrally connected thereto can be produced in one production step, for example as an injection-molded part. The same applies to the intermediate shell. After attaching at least the turbine in the secondary air duct or in the region of an inflow region of the secondary air duct, the intermediate shell can be combined with the lower shell in a simple assembly step.
  • the housing of the vacuum cleaner turbo brush has a cover shell, in which at least one supply air opening or supply air openings are formed for the turbine.

  • the belt transmission 26 is in turn provided in a conventional manner for driving a bristle roller 28 of the vacuum cleaner turbo brush 10.
  • the drive belt 30 provided for that purpose.
