Definitions
- the invention relates first to a method for operating a floor nozzle for absorbing dust by means of a vacuum cleaner, in particular a
- Electric vacuum cleaner in which in the usual feed direction front a vertically movable limiting means is provided.
- the invention further relates to a floor nozzle for a vacuum cleaner, in particular electric vacuum cleaner, wherein the floor nozzle in the usual direction of travel front has a 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 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, so disturb these, however with regard to the inclusion of larger dirt particles, since they do not pass under the limiting means into the Saugraum Scheme, but rather are pushed by the limiting means in the course of the advancing movement of the floor nozzle in front of this. Accordingly, 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 correspondingly dependent on a feed displacement of the floor nozzle.
- a method and a floor nozzle are specified, by means of which the coarse dirt absorption is much easier. While retaining the good particulate matter absorption in connection with the vacuum created in the suction chamber by the lowered limiting means, the arrangement of a sensor for detecting the size property of the dust proves to be advantageous in that the sensor signal is supplied to an evaluation which is dependent on the detected actual - Value and a stored maximum target value actively causes the vertical displacement of the limiting means.
- a dust particle is detected by the sensor whose size characteristic, in particular the size extension in the height direction - ie 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 required is exceeds, so active over the existing in the floor nozzle activating the limiting means is raised.
- the speaking 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 rate in this area required for safe suction in the region of the suction chamber is preferably achieved immediately after a further non-detection of further coarse dirt particles and the associated lowering of the limita tion medium. 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 takes place automatically actively via displacement means of the floor nozzle, preferably without a user-side intervention, in particular force or sliding effort on the part of the user.
- 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 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, resulting in the lifting of 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 linear 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 design of the sensor as UIt- impact sensor possible. The use of an ultrasonic link effectively eliminates the possibility of interference.
- non-contact 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 be 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 the lift may be varied depending on the detected amount of coarse debris, such as in the determination of less coarse dirt by the dust sensor every six seconds, for example, in determining a larger amount of coarse debris every two seconds.
- 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 Begrenzungs ein.
- the drive via an electromagnet, in particular a solenoid with a predefined currentless relief position, which corresponds, for example, the lowered position of the boundary 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 proposed solutions for example the solutions with contact sensors or optical sensors in a linear arrangement, further offer the possibility of probability of partial lifting 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 a first embodiment of a floor nozzle 1 for connection to an electric vacuum cleaner, in particular a household vacuum cleaner, for processing a floor 2 is shown and described.
- the first exemplary embodiment illustrated in FIGS. 1 to 5 is shown in FIG the floor nozzle 1 around 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 mounted pivotably relative to the nozzle body 4 on the nozzle body 4.
- Pivotability is formed via a joint, not shown, with a vertical articulation axis z, which joint is interspersed with the suction channel 6.
- the nozzle head 3 is pivotable about the vertical axis z in a horizontal plane.
- the nozzle head 3 has a circular segment-like ground plan, with a front in the usual position according to Figure 2 front, transversely to the direction of travel r extending straight end edge 9 and a rear, the ends of the end edge 9 connecting, in plan view Vietnameselinienab- sectional edge 10th
- the nozzle head 3 On the bottom side, that is to say starting from the plane of the suction orifice 7 in the direction of the base 2 to be maintained, the nozzle head 3 carries a bristle strip 11 with respect to the usual travel direction r at the rear of the suction orifice 7 along the rounded peripheral edge 10, to form a first By means of this bristle strip 11, the suction orifice 7 is vertically spaced from the floor 2 to be maintained. As a result, a suction space 13 is defined below the suction orifice 7 through the bristle strip 11 at the rear.
- 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 front in the usual direction of travel r limiting means 14 - here the sealing lip 15 - is held vertically movable contrary to the rigid arrangement of the rear limiting means 12 - bristle strip 11, wherein a vertical displacement path quite within the meaning of the invention, a curve or a curved portion with a radius may be equal to or greater than the vertical distance between the suction mouth 7 and 2 to be cared for, corresponding to the vertical slope of the limiting means 14.
- Opening to the suction chamber 13 is released, through which opening coarse dirt - larger dust particles - can get into the suction chamber 13.
- larger dust particles as are provided, for example, in FIGS. 4 and 5 with the reference numeral 17, would be collected and pushed forward in the direction r in front of the limiting means 14 in the case of a conventional forward displacement of the floor nozzle 1.
- Smallest dust particles as provided, for example, with the reference numeral 18, reach the suction chamber 13 even in the lowered position of the limiting means 14.
- a sensor 19 which detects the size property of the dust.
- This sensor 19 is placed in the usual direction of travel r in front of the limiting means 14 and is realized as a light barrier 20 in the first embodiment shown in Figures 1 to 5.
- This is composed in a conventional manner substantially from a light source 21 and an opposite light sensor 22.
- These sensor elements are placed in exposed Eckausformungen 23 of the floor nozzle housing such that a light beam emitted from the light source 21 aligned in parallel to the front edge 9 and thus aligned parallel to the limiting means 14 extends. This with a small vertical distance to the bottom 2, so that in the light beam entering large dirt particles 17 cause a change or deflection of the light beam.
- 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. If larger dirt particles 17 enter the light beam of the light barrier 20, larger dirt particles are detected via the sensor 19, which causes the evaluation means to actively raise the limiting means 14 for the free passage of the larger dirt particles 17 into the suction space 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 active raising and lowering of the limiting means 14 takes place in the illustrated embodiment by means of a drive 24, here in the form of an electromagnet 25. Its electromagnetically to be acted upon armature 26 is biased to its normal position by a spring 27. In the area of the free end, a plunger 28 is articulated to the armature 26. This carries approximately in the middle of its longitudinal extent a circumferential collar 29, which occurs to limit the stop of the basic position, that is, the lowered position of the limiting means 14 against a facing housing portion 30 occurs.
- End of the plunger 28 is hinged a substantially V-shaped lever 31, this in the region of a free end of one of the V-legs.
- the free end of the other V-leg of the reversing lever 31 carries in a cross section as shown in Figure 4 substantially perpendicular to the associated V-leg extending limiting means 14, thus in a normal position, that is in a lowered position of the limiting means 14 of V-legs in this case are aligned substantially horizontally, while the other V-leg, which is hingedly connected to the plunger 28, encloses an acute angle of approximately 60 ° to the limiter-side V-leg.
- 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 pivoting displacement of the reversing lever 31 about the axle body 32, according to which an increase of the limiting means 14 is brought about in approximately vertical direction.
- This raised position of the limiting means 14 is also limited stop. This, for example, by a stroke limitation of the armature 26 in the electromagnet 25. Alternatively, by striking the plunger 28 associated V-leg of the reversing lever 31 against the housing portion 30th
- the limiting means 14 In the lowered position, the limiting means 14 is rearwardly partially supported over the width of the floor nozzle 1 distributed over ribs 33.
- the movement Means 14 learns according to this arrangement in the usual direction of travel r a back support.
- the drive 24 may also be formed by an electric motor, which further acts on the limiting means 14, for example via a cable 34.
- an electric motor which further acts on the limiting means 14, for example via a cable 34.
- FIG. it can be seen that the electric motor 35 acts with its motor shaft on a winding body 40, via which a displacement of the cable 34 can take place. Its displacement to increase the limiting means 14 takes place against the force of a return spring 36.
- the floor nozzle 1 in this second embodiment is provided with a ground-treatment brush 37 to be rotated. This extends in the width direction of the floor nozzle 1 parallel to the end edge 9 within the suction chamber 13, which latter is bounded at the rear by a first limiting means 12 and the front side by a second limiting means 14.
- the floor nozzle 1 according to the embodiment in Figure 6 further comprises a switch 38, by means of which the limiting means 12 and 14 can be raised or lowered at will by the operator.
- This with respect to the front limiting means 14 also via the cable 34 and the electric motor 35.
- the limiting means remain, for example, after switch operation in the raised position until a user-side lowering thereof takes place.
- the sensor system Only in the hard floor function, that is to say with lowered limiting means, is the sensor system used to detect larger dirt particles 17 and the associated automatic raising and lowering of the limiting means 14.
- FIGS. 7 and 8 show, in a further embodiment, an advantageous further development of the first embodiment in which the front limiting means 14 or the sealing lip 15 in the area of the end areas assigned to the light barrier elements - light source 21, light sensor 22 - are on the foot side, ie the floor 2 associated corner cleaning brushes 39 carries.
- Their bristles point outwards in the direction of the light source 21 or on the light sensor 22 and, when the limiting means 14 are raised and lowered, effect a cleaning by sweeping these elements away from dust and dirt particles.
