Definitions

  • the invention firstly relates to a method for operating a floor nozzle for absorbing dust by means of a vacuum cleaner, in particular an electric vacuum cleaner, in which a vertically movable limiting means is provided in the usual direction of advance.
  • the invention further relates to a floor nozzle for a vacuum cleaner, in particular electric vacuum cleaner, wherein the floor nozzle in the usual device has a front vertically movable limiting means.
  • a limiting means for example in the form of a sealing lip or a bristle strip, extending in the rule over the entire suction chamber width, which can correspond approximately to the bottom nozzle width.
  • a limiting means is also provided in the feed direction behind the suction chamber. According to this Saugraumbegrenzung a Saugraumabdichtung is reached, according to which on the surface to be sucked the soil, especially hard floor, or in joints or cracks a high flow rate - high negative pressure - can be generated.
  • the dirt that is to be removed from a floor covering varies in dimensions from a few microns to more than one centimeter.
  • limiting means for absorbing very fine particles because of the required high flow rate of advantage, but these interfere with the inclusion of larger dirt particles, as they do not pass under the limiting means in the Saugraum Geneva, but rather by the limiting means in the course of the advancing movement of the floor nozzle in front of this be pushed.
  • a relatively large opening in the region of the limiting means is required so as to spend the coarse dirt in the region of the suction chamber.
  • a generic floor nozzle which has a front in the feed direction limiting means. This is provided with a cellular wheel, which detects coarse dirt particles sitting on the floor to be cared for.
  • the limiting means is formed in cross-section substantially V-shaped, with a rotation axis in the region of the V-tip.
  • a V-leg is provided with the cell wheel end. If this bucket in the course of the feed movement of the floor nozzle against a coarse dirt particles, this leads due to the support on the particle to a pivotal displacement of the limiting means, after which the second, previously inactive V-limb of the limiting means pivots the coarse dirt in the direction of the suction chamber.
  • the movement of the limiting means for offering a passage opening for coarse dirt particles is carried out according to a feed displacement of the floor nozzle.
  • a method for operating a floor nozzle and a floor nozzle for a vacuum cleaner in which limiting means are moved in response to a negative pressure in the suction chamber or in response to a forward and backward movement of the floor nozzle in the sense of raising and lowering.
  • the US-A1-5 539 953 discloses a built-in a floor nozzle dirt sensor which signals the user by means of lighting means the degree of contamination of the current cleaned area.
  • the invention has the object to provide a method for operating a floor nozzle and a floor nozzle, in which or in which the coarse dirt pickup and the handling of the floor nozzle with respect to the coarse dirt pickup is facilitated.
  • a method and a floor nozzle are specified, by means of which the coarse dirt absorption is much easier.
  • the arrangement of a sensor for detecting the size property of the dust proves to the advantage that thereby the sensor signal is fed to an evaluation, which depends on the detected IstWert and a stored maximum setpoint value actively causes the vertical displacement of the limiting means.
  • a dust particle the size property, in particular the size extension in the height direction - that is measured at an acute angle to the bottom surface up to an angle of 90 ° - the stored maximum value of a particulate matter in which no displacement of the limiting means is required, exceeds, it is actively raised over the existing in the floor nozzle activating the limiting means.
  • the corresponding Signal implemented to lower the limiting means in the sealing position. It may prove to be particularly advantageous if the movable limiting means is kept in the raised position, for example, only so long, due to the sensor system and the associated activation means, until no larger dirt particles are detected any longer.
  • the relatively high negative pressure or the required flow velocity in this area required for safe extraction in the region of the suction chamber is preferably achieved immediately after a non-detection of further coarse dirt particles and the associated lowering of the limiting means. Accordingly, the coarse dirt particles which are brought into the region of the suction space through the active opening of the delimiting means are also safely extracted.
  • the raising or lowering of the limiting means according to the proposed invention is independent of a feed movement of the floor nozzle and thus also independent of the driving dynamics of the floor nozzle.
  • the displacement of the limiting means is automatically carried out actively via displacement means of the floor nozzle, preferably without user-side intervention, in particular user-side force or sliding effort.
  • the active raising or lowering is performed by a device's own, acting on the limiting means drive.
  • the drive can act on the limiting means, for example via deflection means, alternatively also directly.
  • deflection means for example, levers, spring-loaded cables or even a rotational movement in a translational movement translating means, such as thread or screw helix.
  • the device's own drive for shifting the limiting means is controlled by the sensor signal.
  • a user intervention may be provided, for example, to determine the limiting means in the raised position, regardless of detected sensor signals or alternatively to the determination of the limiting means in the lowered position.
  • the determination in the raised position proves to be advantageous in floor nozzles, which further has a rotatable brush, for mechanical action on carpets.
  • floor nozzles which further has a rotatable brush, for mechanical action on carpets.
  • the suction chamber is sealed by the carpet pile.
  • Limiting means which serve for the extraction of hard floors or the like for sealing the suction chamber, are raised in such a configuration of the floor nozzle, as they would otherwise complicate the displacement of the floor nozzle on the carpet.
  • the sensor for detecting the size property of the dust may be a non-contact type sensor. This detects the area, in particular in the feed direction in front of the floor nozzle and thus controls early if necessary lifting the limiting means.
  • the sensor may be formed, for example, as a light barrier, with a light source and a light sensor, which monitor the area in front of the floor nozzle opposite one another.
  • the emitted light beam in this case runs close to the ground in approximately parallel alignment with the nozzle leading edge in the feed direction, preferably over almost the entire width of the floor nozzle, in particular over the entire width of the limiting means to be raised or lowered.
  • An interruption of the light beam, which is detected by the light sensor is translated as a coarse dirt element, with the result of lifting the limiting means.
  • the active elements of the light barrier namely the light sensor and the light source can alternatively also be arranged within the device in a protected position, so on, for example, together with an evaluation on a common board.
  • the light barrier can work as a transmitter with laser light instead of a light emitting diode.
  • the light barrier operates with a coded signal, so further preferably in conjunction with a conventional light barrier with light-emitting diode. Any extraneous light influences are detected and filtered out. The light is pulsed emitted as a constant frequency.
  • the frequency is determined from the signal, a match meaning that there is no dirt or no coarse dirt leading to lifting of the limiting means and no extraneous light. If the receiver detects constant light, an external light is to be assumed which does not lead to activation of the drive acting on the limiting means. The longer absence of the light frequency indicates coarse dirt placed in front of the floor nozzle, according to which a lifting of the limiting means is initiated.
  • the limiting means may have on the optical means, such as light sensor and light source, facing head ends cleaning means, such as small brushes, which wipe the optical elements when lifting or lowering the limiting means and so remove dust or dirt particles of these.
  • a single optical sensor can also create an image of the ground in front of the floor nozzle or in front of the limiting means from linearly determined distance values. The deviations caused by coarse dirt particles are detected, after which the limiting means is actuated. In this case, an optical scanning of the bottom area in front of the limiting means takes place.
  • a comparative operation such as such an optical sensor can be achieved with a linear arrangement (array) of reflection elements (transmitter / receiver). These determine the distance standing almost perpendicular to the ground surface. Deviation or absence of reflection is recognized as coarse dirt.
  • the optical sensors is also the formation of the sensor as an ultrasonic sensor possible. The use of an ultrasonic link effectively eliminates the possibility of interference.
  • contactless sensors may also be designed, for example, as capacitive or inductive proximity switches, which react correspondingly to coarse dirt particles having certain size properties.
  • the senor is designed as a contact sensor, reacting to a contact with lying in front of the floor nozzle or before the limiting means coarse dirt.
  • the limiting means itself can be designed as a touch sensor.
  • the sensor is designed as a capacitor.
  • the limiting means itself is constructed in the form of a capacitor, wherein two thin films form the surfaces of a capacitor and the limiting means between these films preferably arranged in the form of a sealing lip the dielectric. The variance of the capacitance caused by the action of the outer film contacting coarse dirt particles is evaluated, for example, in a simple resonant circuit.
  • the sensor is designed as a piezoelectric element, so on, for example, in the form that on the formed as a sealing lip limiting means a piezo film is mounted, the mechanical contact can be evaluated by coarse dirt particles.
  • the dust already located in the interior of the floor nozzle is evaluated.
  • the limiting means is raised or lowered.
  • the limiting means cyclically raised to periodically suck in the coarse dirt accumulated in front of the restriction means.
  • the cycle time for lifting may be varied depending on the amount of coarse dirt detected, such as when the coarse dirt is detected by the dust sensor every six seconds, and when a larger amount of coarse debris is detected every two seconds, for example.
  • the floor nozzle can be equipped with one of the above-described non-contact sensors or touch sensors. It is also possible a combination of several such and different sensors on a floor nozzle.
  • the drive for raising or lowering the limiting means for example, via a separate, recorded in the floor nozzle electric motor.
  • This can further preferably have an automatic Endticianabscnies when reaching the raised or lowered Begrenzungswolf.
  • the drive via an electromagnet, in particular a solenoid with a predefined currentless relief position, which corresponds for example to the lowered position of the limiting means.
  • the drive via a shape memory metal element.
  • this element has a preferred unloaded basic position, in which more preferably the limiting means remains in the lowered position.
  • the element is energized for example, whereupon the metal element is subject to a temporary deformation, which shape change is converted into a movement of the limiting means. After canceling the current application the shape memory metal expires again in the original position.
  • the solutions proposed, for example, the solutions with touch sensors or optical sensors in a linear arrangement continue to offer the possibility a partial raising and lowering of the limiting means. Accordingly, in this case the limiting means is not raised over the entire width of the floor nozzle upon detection of coarse dirt, but rather only the area in front of which the detected coarse dirt is located. Accordingly, the flow velocity and the desired negative pressure in the suction chamber remain virtually unchanged even when the limiting means section is raised.
  • FIG. 1 Shown and described is first with reference to FIG. 1 a first embodiment of a floor nozzle 1 for connection to an electric vacuum cleaner, in particular household vacuum cleaner, for processing a floor 2.
  • the floor nozzle 1 is a hard floor nozzle.
  • the floor nozzle 1 is composed essentially of a nozzle head 3 seated on the base 2 to be maintained and a nozzle body 4 connecting the nozzle head 3 with the vacuum cleaner, not shown, wherein a connecting piece 5 is formed on the nozzle body 4 for connection of the nozzle 1 the vacuum cleaner. Through the nozzle body 4 extends from the connecting piece 5, starting a suction channel 6, which opens into the nozzle head 3.
  • the suction mouth is provided with the reference numeral 7.
  • the nozzle body 4 extends between the nozzle head 3 and the rollers 8 associated with the connection piece end, with the nozzle body 4 tapering in its transverse width to the normal travel direction r, starting from the region of the rollers 8 to the end facing away from it.
  • the nozzle head 3 is pivotable about the vertical axis z in a horizontal plane.
  • the nozzle head 3 has a circular segment-like outline, with a in the usual position according to FIG. 2 in the direction of travel r front, transversely to the direction of travel r extending rectilinear end edge 9 and a rear, the ends of the end edge 9 connecting, circular in plan outline edge 10th
  • the nozzle head 3 On the bottom side, that is, starting from the plane of the suction orifice 7 in the direction of the soil 2 to be maintained, the nozzle head 3 carries with respect to the usual travel direction r at the rear of the suction orifice 7 along the rounded peripheral edge 10 a bristle strip 11, to form a first limiting means 12 Over this bristle strip 11, the suction mouth 7 is vertically spaced from the floor to be maintained 2.

  • the suction chamber 13 is further limited along the front end edge 9.
  • the second limiting means 14 arranged there is a sealing lip 15, for example consisting of a rubber-like soft plastic.
  • the suction chamber 13 is further subdivided in the illustrated embodiment by four occasionally arranged, in the direction of the suction mouth 7 facing bristle rows 16th

  • the light barrier 20 is placed in front of the limiting means 14 at a small distance to this, which horizontal distance is dimensioned such that at normal travel speed of the floor nozzle 1 when detecting large particles of dirt 17 on the photocell 20 a sufficient reaction time for lifting the limiting means 14th remains.
  • the signals detected by the sensor 19 are evaluated by an electronic unit, not shown. Enter larger dirt particles 17 in the light beam of the light barrier 20, so just larger dirt particles are detected via the sensor 19, which causes the evaluation of the active raising of the limiting means 14 for free passage of the larger dirt particles 17 into the suction chamber 13. As soon as no larger dirt particles 17 are detected any longer, the limiting means 14 is immediately moved actively back into the lowered position.

  • the reversing lever 31 is pivotable about a housing-side axle body 32. This extends in the width direction of the floor nozzle 1, corresponding to parallel to the front end edge 9 and to the longitudinal extension of the limiting means fourteenth
  • the electromagnet 25 Upon detection of larger dirt particles 17 via the sensor 19 or via the light barrier 20, the electromagnet 25 is activated via the evaluation electronics, not shown, which causes the armature 26 to be attracted against the force of the spring 27. This results on the plunger 28, a pivotal displacement of the reversing lever 31 to the axle body 32, according to which an increase of the limiting means 14 is brought about in an approximately vertical direction.
