Definitions

  • the invention relates to a floor suction device, in particular attachment or part of an electric vacuum cleaner, preferably suction brush device for caring for carpets or hard floors, with a drivable, rotating brush and a suction space which is limited by curtain means, the curtain means being able to be raised relative to the floor vacuum device are lowerable.
  • Floor suction devices of this type are known, and these are arranged, for example, via a pipe coupling on an electric vacuum cleaner or the like. These floor suction devices have a separate electric drive for rotating a brush roller arranged in the device. Textile surfaces are usually cleaned by vacuuming the dirt, which is loosened by the brush roller located in a mouthpiece and reaching into the carpet. When cleaning hard floors there is a risk that the edges of the mouthpiece touching the hard floor will damage it. To avoid this, the suction mouth on hard floors is lifted off the floor to be maintained. This is done, for example, by bristle strips which are arranged around the suction mouth. This increase in the overall nozzle increases the air inlet opening of the suction mouthpiece.
  • curtain means all on a plate which can be moved perpendicular to the floor surface to be worked, which plate is arranged around the suction mouthpiece.
  • This carrier plate can by means of a Mechanics can be extended and retracted, whereby the suction mouth is lifted from the floor to be maintained. It proves to be particularly disadvantageous here that such a device requires a relatively large storage space in the mouthpiece and thus increases the overall height of the mouthpiece. However, this prevents the floor from being cleaned under furniture or the like.
  • the object of the present invention is to improve a generic floor suction device in a technically simple manner, above all in such a way that optimum suction power is given both on carpets and on hard floors.
  • a floor suction device which has an optimal suction power both on carpets and on hard floors.
  • the curtain means can be moved independently of a floor clearance of the floor suction device. Accordingly, the variability of the suction space or an adjustability of the suction gap of the suction space resulting with respect to the floor is achieved by activatable curtain means which can be raised or lowered without changing the height of the floor suction device as a whole or the brush or brush roller. In contrast to the known prior art, it is not necessary to raise the floor suction device or the suction brush device to activate the curtain means.
  • the Distance between a base plate of the device and the floor to be maintained can remain the same both when caring for carpets and when caring for hard floors.
  • This distance is given in a known manner in that the device is provided with wheels or the like.
  • the curtain means remain in a raised position.
  • the dirt is sucked out, which is loosened by the brush located in a mouthpiece of the device and reaching into the carpet.
  • the air inlet opening of the suction mouthpiece is limited here by the support of the edge edges of the suction mouthpiece on the carpet pile.
  • curtain means are lowered in such a way that they rest on the hard floor to be maintained and thus limit the suction space.
  • the activation or reactivation of the curtain means can be achieved, for example, by pivoting the curtain means from a lowered position to a raised position or vice versa.
  • the curtain means can thus, for example, be attached to the bottom of the floor suction device so as to be movable.
  • the aforementioned curtain means serve as a seal for limiting the suction space when maintaining hard floors in the form of a lip or a row of brushes.
  • the curtain means can be guided in a backdrop in such a way that the curtain means are lowered and pivoted by an essentially translatory movement of a frame edge of the curtain means. This configuration can require a certain rigidity of the curtain means.
  • the lowering or raising of the curtain means can be operated by a switch, for example via a foot switch of the floor suction device.
  • the lowering of the curtain means can be supported in that a spring preload acts in the lowered position.
  • a spring preload acts in the lowered position.
  • a lip is provided as a curtain means, it can also be accommodated in a guide, in particular an edge-side guide with respect to a longitudinal extension of the lip, so that its tip is still trapped in this guide even in the raised state.
  • a guide in particular an edge-side guide with respect to a longitudinal extension of the lip, so that its tip is still trapped in this guide even in the raised state.
  • the axis of rotation can be held on and moved with an essentially translationally movable carriage
  • the aforementioned embodiment can be designed in such a way that for sealing the suction space in the front area and possibly also laterally Bristle strips can be lowered as curtain means, with a very thin, flexible sealing lip being arranged in the rear area (with regard to a direction of travel of the floor suction device), which can simultaneously perform a translatory and rotary movement, as a result of which it assumes a position perpendicular to these when vacuuming hard surfaces .
  • the sealing lip is positioned essentially in a position parallel to the surface to be extracted, free of mechanical stresses and protected against unnecessary contamination, this position at the same time avoiding wear-related malfunctions and the danger greatly reduced from incorrect operation.
  • the rear edge of the suction space is sealed according to the invention by a thin and flexible sealing lip which is in a position perpendicular to the hard floor. If the sealing lip is sufficiently flexible, damage to the hard surface to be cleaned by dirt particles can be avoided.
  • such a sealing lip has a high self-cleaning effect, so that the risk of jamming of the sealing lip due to the accumulation of dirt can be avoided in connection with the translatory-rotational movement of the lip.
  • the above-described embodiment of the invention allows a very small overall height of only a few millimeters by using small-sized components. Furthermore, a very low overall height can be achieved by using small wall thicknesses of the backdrop and integrating it directly into the floor of the floor suction device. It is also conceivable that in the hard floor cleaning operation the air intake opening, ie the gap of the suction space with respect to the floor, is reduced leaves that the suction mouthpiece is provided by means of a two-part seal on the bottom side of the mouthpiece.
  • a row of bristles which as a rule cannot be adjusted in height, can be provided as a seal, while a height-adjustable seal in the form of a sealing lip, but possibly also in the form of a further row of bristles, is provided on the rear.
  • the seal can be divided into two parts from a sealing mechanism that extends over a width and one or both side edges of the mouthpiece or across a width of the mouthpiece, or from a sealing mechanism or curtain means that extends over the motor or brush side of the mouthpiece.
  • the floor suction device has its own motor, which is arranged behind the mouthpiece in the direction of travel of the floor suction device.
  • the one curtain means which forms the height-adjustable seal in the form of a lip or a row of brushes, can further be designed as a sealing film which extends over a partial area of the bottom side of the mouthpiece and bulges over a width of the mouthpiece in the direction of the bottom, in particular the hard bottom.
  • This can be realized in an advantageous manner in that the curtain means can be lowered or raised, in particular a height-adjustable seal in the form of a lip, by folding or unfolding a membrane part.
  • the unfolded membrane part rests essentially on an underside of a bottom of the floor suction device. This also gives a low overall height of the curtain means formed in the form of a membrane part.
  • the curtain means in the form of a membrane part can be raised or lowered by folding or unfolding transversely to an essentially horizontal displacement movement of a folding end region of the membrane part.
  • the membrane part is designed as a sealing film
  • a bulge can be carried out so far that it extends to the hard floor to be vacuumed.
  • An outer apex line of the bump formed in this way can therefore lie on the floor or rub over it, when the floor suction device is moved.
  • an adjustment can be made in that the sealing film is stored or extends on the bottom side of the mouthpiece without bulging, ie in a stretched form.
  • the sealing film itself can consist of an elastic, resettable material, in particular of plastic or a metal foil.
  • the sealing film can also be constructed in multiple layers, namely from one or more layers of an elastic, resilient material, in particular plastic material, and from one or more layers of an elastic and resilient metal film.
  • the sealing film can also be covered on the outside with bristle hair. There is then a combined row of bristles and sealing film as a seal or curtain means.
  • the sealing film can also have one or more interruptions across the width of the mouthpiece. In particular, it is then also possible to activate only individual sections of the sealing film in the sense of bulging.
  • the sealing film can also have two bulges, in particular seen in a longitudinal cross section, so that two bulge apex lines are formed one behind the other in the direction of travel.
  • the sealing film can also have two or more Have material thicknesses.
  • the bulging and resetting of the sealing film can be achieved by a slide which compresses or tightens the sealing film and which can be moved mechanically.
  • the slide can also be movable by means of an energy source located inside or on the suction mouthpiece. For example, by an electric motor. Overall, it is essential that the lowering of the lip can be carried out by means of an installation that takes place in the course of an essentially horizontal displacement.
  • a total height adjustment known per se can also be provided in the case of a floor suction device of the above-described embodiments, which, however, is not essential for raising or lowering the curtain means.
  • the latter can be raised or lowered independently of any height adjustability.
  • this means that the curtain means can be raised or lowered both in a low position and in a high position of a height-adjustable floor suction device.
  • the height of the rotatable brush can also be provided, optionally further and in combination, whereby this design also ensures that the movement of the curtain means is independent.
  • the invention further relates to a suction mouthpiece for a cleaning device, in particular for a floor suction device with a floor touching the floor to be sung in the carpet cleaning operation and preferably lifted off the floor to be vacuumed in the hard floor cleaning operation, with a rotatable, motor-operated brush roller or similar mouthpiece.
  • a suction mouthpiece for a cleaning device in particular for a floor suction device with a floor touching the floor to be sung in the carpet cleaning operation and preferably lifted off the floor to be vacuumed in the hard floor cleaning operation, with a rotatable, motor-operated brush roller or similar mouthpiece.
  • the delimitation of the suction space can be achieved partly by stationary curtain means and partly by an activatable curtain means.
  • the design can be chosen so that the stationary curtain means are arranged in a fixed position on the bottom of the floor suction device, preferably in front of (with regard to a direction of travel of the floor suction device) the suction space and to the side of the suction space.
  • the activatable curtain means is accordingly preferably arranged to be raised or lowered on the rear side of the suction space, and here, too, the activatable curtain means can be raised or lowered independently of the respective height of the mouthpiece. All of the above-mentioned embodiments of raising or lowering curtain means can be used here.
  • the said curtain means can be designed as a lip. It is also conceivable to form a row of bristles as curtain means.

When vacuuming carpet fringes or the like, it is expedient to switch off the electric motor drive, the brush bristles also being raised here.
  • Hard floors are optimally vacuumed when the bristles rest on the floor and the electric motor drive is switched off here. However, it is also conceivable to switch on this drive for improved maintenance.
  • the suction brush device has a switch which both lowers and raises the sweeping bristles and switches the drive on or off.
  • the brush drive is switched off when the bristles are lowered. This means that in the course of lowering the bristles arranged in front of the rotating brush, the electric motor drive of the brush is also switched off.
  • the brush drive can be switched on or off when the bristles are raised.
  • the electric motor drive of the rotating brush is switched on.
  • Such a position of the switch can be defined as the basic position. From this basic position, the electric motor drive can be switched off via the switch, for example when carpet fringes or the like are to be extracted.
  • switching on the drive would cause the fringes to wind up on the rotating brush, which could lead to damage to the carpet or to a defect in the suction brush device.
  • the device according to the invention is particularly optimized in terms of handling in that the switching operation can be carried out via a foot switch.
  • This foot switch is expediently arranged in an easily accessible area of the suction brush device. It is also conceivable here to arrange two foot switches arranged in parallel on both sides of the tubular foot of the electric vacuum cleaner. In the case of foot switches which have a mechanism for lowering or lifting the bristles and switching the drive on or off, the foot switches are connected to one another in a rotationally fixed manner. Such a mechanism can preferably be designed such that the foot switch is connected to the bristles or to a bristle strip via a Bowden cable. A bristle strip which is preferably used in a suction brush device can thus be brought into a lowered or raised position depending on the actuation of the foot switch by means of the Bowden cable via deflection rollers. This design can be optimized in that the bristles or bristle strip are loaded in their lowered position by a compression spring.

  • the electric drive of the brush roller is switched off when cleaning hard floors.
  • This can also be taken into account in the above-mentioned design, in that when the upper switch is actuated more strongly and the associated lower switch is operated, on the one hand the curtain means are lowered and on the other hand the electric motor of the brush roller is switched off or vice versa.
