Definitions

  • the invention relates to a Staubsauger foundeddüse according to the preamble of claim 1.
  • canister vacuum cleaners In so-called canister vacuum cleaners, the motor, blower, filter unit and electronic devices are arranged in a housing, which is usually mounted on rollers.
  • An often telescopically adjustable in length suction pipe is connected at one end by means of a flexible suction hose to the housing or the blower of the vacuum cleaner and has at its other end to a floor nozzle, which comes into contact with the surface to be cleaned.
  • a second design form the so-called hand vacuum cleaner.
  • the suction pipe is rigidly connected to the vacuum cleaner housing.
  • engine, blower, electrical and filter unit are housed in the housing.
  • This additionally has on the side opposite the suction pipe connection on an extension of the suction pipe attached handle for handling.
  • the negative pressure generated by the motor and blower is applied to the surfaces to be cleaned.
  • These are usually either hard, smooth surfaces of floor coverings such as parquet, PVC, stone, etc., or textile surfaces such as carpets, furniture upholstery, etc.
  • the different nature of the surface partially conflicting demands on the functionality of floor nozzle.
  • air-permeable surfaces such as carpets
  • the best possible resting of the floor nozzle is desirable in order to achieve a deep and high suction effect.
  • the direct suction is often insufficient to release stuck dirt particles from the surface.
  • Floor nozzles are therefore usually equipped with one or more bristle strips. These are arranged so that their bristles extend from the bottom of the floor nozzle, which contacts the surface to be cleaned, substantially perpendicular to the floor nozzle. These bristles are usually by means of a foot switch on the floor nozzle via a mechanism between a extended position in which the bristles protrude from the bottom of the floor nozzle and so can come into contact with the floor covering and optionally create a distance between the nozzle and floor covering and one lowered position in which they are essentially retracted without function in the floor nozzle, switchable.
  • the invention builds on the generic Staubsauger convinceddüse in that the switching device has a third switching position in which the bristle strip automa- table can assume the first or the second position. In this third switching position, neither the first nor the second position is prescribed for the bristle strip. In particular, the bristle strip is fixed neither in the first nor in the second position, but can automatically, depending on the current conditions of the cleaning process with the Staubsauger convinceddüse, occupy the first or second position and change between two positions.
  • the position of the bristle strip in the third switching position takes place without direct intervention of the operator. Consequently, the operator can carry out a targeted floor care via the first or second switching position, in which case the bristle strip is in the first or in the second position.
  • the user can perform a simplified floor care by means of the vacuum cleaner floor nozzle by bringing the switching device in the third switching position in which the bristle strip automatically selects their respective position. This frees the user from selecting the respective suitable position of the bristle strip and in particular from interrupting the cleaning operation for actuating the switching device. In this way, the cleaning process with the Staubsauger convinceddüse invention particularly simple.
  • the change takes place between the first and the second position of the bristle strip in dependence on the surface to be cleaned. Since, as already explained above, the different surfaces to be cleaned make different demands on the Staubsauger convinceddüse, changing the surface quality is usually the reason for changing the position of the bristle strip.
  • the changeover between the two positions takes place automatically in the third switching position, so that this embodiment particularly facilitates the work.
  • the change takes place between the first and the second position of the bristle strip as a function of the direction of movement of the vacuum cleaner floor nozzle.
  • a change in the position of the bristle strip depending on the direction of movement is particularly on carpets and other structur - A -
  • an alternative embodiment of the invention provides that the first position of the bristle strip is primarily for carpets and the second position is primarily for hard floor coverings.
  • the first position corresponds to a position which is lowered, for example, into the housing of the vacuum cleaner floor nozzle.
  • the bristle strip protrudes from the housing of the vacuum cleaner floor nozzle and thus exerts a brushing effect on the floor covering to be cleaned.
  • the switching device comprises a roller switch.
  • a roller switch By means of a roller switch, the desired switching position of the switching device can be adjusted by the user.
  • other switching mechanisms such as a slide switch, a pressure switch, a transfer switch or the like can be used.
  • the switching movement of the switching device is communicated to the bristle strip via a driver-pin mechanism.
  • a driver may be attached to the switching device, which transmits the movement caused by the actuation of the switching device to a pin and further to the bristle strip.
  • the movement can take place via a linkage, via gears or the like.
  • the driver is designed substantially V-shaped.
  • the V-shaped carrier can be designed in particular for the realization of the three-stage mechanism for the control of the bristle strip. the.
  • a pivoting of the V-shaped driver about an axis which is perpendicular to the plane spanned by the two legs through the intersection of the two legs, allows a precise definition of the position of the entrained pin at the two end points of the rotational movement. In a middle position, a certain mobility of the pin can be achieved, which allows a change of the bristle strip between the two positions.
  • the bristle strip passes from the first to the second position by means of gravity.
  • reset elements such as springs or the like may be provided.
  • the invention is based on the knowledge to provide a third switching position in addition to the two switching positions for a bristle strip according to the prior art. In this switching position, the bristle strip can move freely between its two positions. With an appropriate structural design, an automatic function for the bristle strip can be realized in this way.
