Definitions

  • the invention relates to a vacuum cleaner nozzle, in particular a static vacuum cleaner floor nozzle with a housing, a suction mouth arranged on the underside of the housing, a suction connection piece for connection to a suction line and a suction channel which connects the suction mouth to the suction connection piece.
  • the vacuum cleaner nozzle also includes a secondary air duct.
  • Vacuum cleaner nozzles are used to shape and channel the suction air flow generated in a suction device on a surface to be cleaned, in particular a floor surface.
  • the design of the vacuum cleaner nozzle is essential for the cleaning properties of a vacuum cleaner.
  • the amount of dirt particles that can be loosened from the surface to be cleaned and transported away in the suction air flow depends to a large extent on the local flow velocities of a suction air flow entering a vacuum cleaner nozzle and on the pressure differences present.
  • the vacuum cleaner nozzle also serves to distribute the suction air flow over the largest possible cleaning surface so that large surfaces can be processed quickly.
  • One way to reduce the sliding resistance is to reduce the suction power.
  • the electrical power of the blower for generating the suction air flow could be throttled or a false air valve could be provided in the suction air duct, usually on a handle of the suction pipe.
  • this can have the disadvantage that there is not enough suction power available on the vacuum cleaner nozzle and in the part of a suction air duct connected to it - for example a suction pipe - to safely remove the loosened dirt.
  • the suction line usually has a greatly enlarged flow cross section compared to the inlet gap on the vacuum cleaner nozzle. As a result, the flow rate is reduced.
  • the invention is therefore based on an application scenario in which the suction power applied to the vacuum cleaner nozzle is not reduced and nevertheless the handling is greatly improved by reducing the negative pressure in the suction nozzle.
  • the vacuum cleaner nozzle has a secondary air duct. Secondary air or false air is to be understood as an air flow which is fed to the suction connection nozzle at the vacuum cleaner nozzle without taking the air path provided for cleaning, in particular through the suction mouth.
  • Vacuum cleaner floor nozzles are known in which an automatic secondary air valve opens when the vacuum in the interior of the vacuum cleaner falls below a certain level and thus enables a secondary air flow.
  • part of the suction channel is designed as an elastic hose. Slits in the hose wall mean that they can be elastically deformed independently of one another and thus opened by the action of a vacuum.
  • the disadvantage here is that the opening and closing characteristics of the secondary air valve are fixed when the vacuum cleaner nozzle is designed and cannot be influenced subsequently.
  • the user cannot effectively counteract wear of the elastic parts. Due to the free movement of the valve parts in addition to that of air valves is always occurring noise to fear an additional noise development due to vibrations and resonances of the valve parts.
  • the invention is based on the object of specifying a vacuum cleaner nozzle with a pushing force reduction by means of secondary air guidance, which overcomes the disadvantages of the prior art. In particular, it should be easy and precise to use and minimize noise.
  • the invention is based on a generic vacuum cleaner nozzle, in particular a static vacuum cleaner floor nozzle with a housing.
  • Static vacuum cleaner nozzles do not have any additional movably driven cleaning agents such as bristle rollers, but only achieve the cleaning effect by means of the suction air flow.
  • the housing of the vacuum cleaner nozzle can in particular be constructed in several parts and, for example, have a housing chassis and at least one cover arranged on the housing.
  • a suction mouth is arranged on the underside of the housing. This designates an opening through which a suction air stream enters the interior of the housing during use.
  • the suction mouth usually has an elongated shape which is elongated in a transverse direction running transversely to the working direction of the vacuum cleaner nozzle.
  • a suction connection piece is provided for connection to a suction line.
  • the suction connector is usually connected to the housing such that it can move about at least one pivot axis.
  • the vacuum cleaner nozzle comprises a suction channel, which the Connects the suction mouth with the suction connector.
  • the suction channel is fluidly connected directly or indirectly to the suction mouth and the suction connection piece.
  • the vacuum cleaner nozzle has a secondary air duct, by means of which an air stream can be supplied to the suction connection piece which can be connected to the suction line, bypassing the suction mouth.
  • the secondary air duct is formed with an opening formed in the suction channel and with a flap movably arranged within the housing.
  • the flow cross section of the secondary air duct can be adjusted by the distance between the flap and the opening.
  • the opening connects the interior of the suction channel to an area within the housing which is fluidly connected to the surroundings.
  • the volume flow of secondary air can be adjusted via the variable (minimal) flow cross-section of the secondary air duct.
  • the flow resistance increases as a result of the secondary air duct, the smaller the flow cross section between the opening in the suction channel and the flap designed as a separate part is set.
  • the flap can completely cover the opening, so that the secondary air flow is completely prevented.
  • the flap can be moved within the housing in particular in a region in which the minimum flow cross section of the secondary air duct is formed by a region between the edge of the opening and the flap.
  • the suction channel has a collecting space arranged above the suction mouth and a tubular section running in the longitudinal direction of the vacuum cleaner nozzle (working direction).
  • the collecting space and the tubular section are connected to one another by a dome.
  • the opening of the suction channel is arranged on the dome opposite the tubular section.
  • the opening is trapezoidal.
  • the surface of the flat opening can thus be optimally used in the case of a tapering or rounded suction channel - for example in a dome-shaped area.
  • the larger side of the trapezoidal shape is also reinforced, which can be used for targeted control.
  • the flap is particularly preferably movable by an operating element arranged on the outside of the vacuum cleaner nozzle.
  • the flap By actuating the control element, the flap can move between at least two positions are moved, which result in a different minimum cross section of the secondary air duct.
  • the flow cross section can be adjusted continuously in a certain range. Thanks to the control element, which is accessible from the outside, the flow cross-section can be easily adjusted during operation and readjusted as required even when the floor covering is changed.
  • the control element is particularly preferably designed as a rotary knob or rotary knob.
  • a rotating control element can be used in an angular range of more than one complete revolution. As a result, both a large setting range and high accuracy can be achieved.
  • the flap is designed to be movable by a spindle drive.
  • a spindle drive can be connected directly to a rotatable control element.
  • a spindle drive can be implemented in a very small space. Here it provides a stepless and powerful adjustment option.
  • a spindle drive with a suitable design is designed to be self-locking, so that the negative pressure inside the vacuum cleaner nozzle and dynamic loads on the secondary air flow do not lead to an adjustment of the flap.
  • the flap is guided in a longitudinally displaceable manner on guide devices of the vacuum cleaner nozzle, in particular of the suction channel.
  • the mobility of the flap is reduced solely to linear displacement in one direction as a result of the positive guidance formed by the guide device.
  • displacement of the flap over the entire circumference results in a uniform change in the air gap.
  • the direction of displacement stands in particular perpendicular to the plane in which the edge of the opening lies or in which the surface of the flap runs. The forced guidance prevents rattling due to undesired movement of the flap in the air flow.
  • the guide devices are particularly preferably integrally formed as projections on the suction channel. Correct alignment of the flap in relation to the opening formed on the suction channel is thus automatically ensured. At least one of the projections can optionally have at least one latching element with which the flap is held within the guide.
  • the flap can be made pivotable.
  • An elastic plastic molded body is particularly preferably arranged between the flap and the opening.
  • the elastic molded plastic body prevents noise when the flap comes into contact with the edges of the opening and, depending on the position of the flap, can also serve as a seal.
  • the plastic molding is expediently connected to the flap.
  • it is glued to the side of the flap facing the suction channel over a large area, particularly over the entire area. This ensures secure positioning of the molded plastic body.
  • the molded plastic body is formed from open-cell foam.
  • the secondary air flow is then partially or completely passed through the pores of the plastic foam. This can lead to a finer one Setting the free flow cross section can be used.
  • the secondary air flow is distributed and calmed down in the pore material, so that less flow noise occurs than at a gap delimited by hard edges.
  • the opening is preferably divided into several partial openings by webs.
  • the webs or rungs can be used to support, to calm the flow and / or, if necessary, to support the molded body. Furthermore, they serve to protect the flap from dirt particles drawn into the air flow through the suction mouth.
  • a vacuum cleaner nozzle according to an embodiment.
  • This comprises a housing, which is composed of a housing chassis 2 and a cover 3.
  • a coupling piece 4 which is mounted so as to be tiltable about a pivot axis running in a transverse direction y, and at the rear end thereof about a second tilting axis a suction connection piece 5 is pivotally mounted.
  • Two support rollers 6 are also arranged on the coupling piece 4.
  • the suction connection piece 5 is connected to the housing 1 by means of a corrugated hose 7.
  • the air flow inside the housing is shown in the sectional views 2A to 2C. It can be seen there that a suction mouth 8 is arranged on the underside of the housing 1 and is connected to the suction connection piece 5 in terms of flow technology via the corrugated hose 7. Furthermore, a secondary air duct is formed within the housing 1 under the cover 3. For this purpose, an opening 10 is formed within a suction channel 9, which connects the suction mouth 8 with the suction connection piece 5. Furthermore, a flap movably arranged within the housing 1 is provided. The flow cross section of the secondary air duct can be adjusted by the distance s between the flap 11 and the opening 10.
  • Figure 2B a semi-closed position.
  • the distance s between the flap 11 and the opening 10 is reduced, so that only a reduced secondary air flow 12 can enter the suction channel.
  • Figure 2C shows a completely closed position, in which the gap is closed so far that no or no significant secondary air components get into the suction channel 9.
  • the suction channel 9 has a collecting space 13 arranged above the suction mouth 8 and a tubular section 14 running in the longitudinal direction / working direction (x) of the vacuum cleaner nozzle.
  • the tubular section 14 simultaneously forms the connection area for the corrugated hose 7.
  • the collecting space 13 and the tubular section 14 are connected to one another by a dome 15.
  • the opening 10 is arranged on the dome 15 opposite the tubular section 14. As indicated by the flow arrows, this results in a particularly low-turbulence confluence of the secondary air flow 12 with the cleaning air flow 16 entering through the suction mouth 8.
  • the suction channel 9 is formed in several parts in the embodiment.
  • the component forming the dome 15 and the tubular section 14 is separate in FIG Fig. 3 shown.
  • the figure shows a rear view looking forward in the working direction x. It can be clearly seen that the opening 10 as a whole has a trapezoidal shape which is mirror-symmetrical with respect to the longitudinal center plane of the vacuum cleaner floor nozzle and is designed with a longer lower edge and a shortened upper edge.
  • the opening 10 is also divided into several areas by a plurality of webs 17.
  • the flap 11 is movable by an operating element arranged on the outside of the housing 1.
  • the control element is designed as a rotary knob 18. If you especially in the Figures 2A to 2C can recognize, the mobility is provided by a spindle drive.
  • the rotary knob 18 is formed with an extension 19 on which an external thread is arranged. The external thread engages in an associated internal thread 20 of the flap 11. The distance s between the flap 11 and the opening 10 can be adjusted by turning the rotary knob 18.
  • the flap 11 is linearly positively guided on the suction channel 9 by projections 21 in the direction of displacement 22. Locking elements 23 at the ends of the projections 21 prevent the flap 11 from falling out of the positive guide.
  • an elastic plastic molded body 24 is arranged between the flap 11 and the opening 10. This is designed as an open-pore foam body through which air can flow.
  • the elastic molded body 24 is glued over the entire surface to the inside of the flap 11 facing the suction channel 9. Furthermore, the open-pore foam body 24 is supported in the webs 17 within the opening 10.
