Definitions

  • the present invention relates to a floor nozzle for a vacuum cleaner according to the preamble of claim 1, wherein the floor nozzle has a suction channel and at least one suction mouth extending therefrom and wherein the suction mouth is delimited by a suction mouth edge at least in a usual direction of movement of the floor nozzle during operation.
  • a floor nozzle which has a sliding sole on the underside with two channel-shaped depressions in which a thread take-up made of resiliently flexible material is arranged.
  • a floor nozzle for vacuum cleaners is known, the floor nozzle having a suction mouth which is delimited by suction mouth edges.
  • the floor nozzle has agitators in front of and behind the suction mouth, which act on the surface to be cleaned.
  • the carpet pile is brushed up by a bristle roller or the like (agitator) comprised by such floor nozzles, and dirt is thus mechanically removed from the carpet fibers.
  • the sucked air flows behind the suction mouth edges directly into the suction mouth and from there into the suction channel opening and not through the opening opened by the bristle roller Carpet pile.
  • the total amount of air is accordingly not yet optimally used with current embodiments of floor nozzles.
  • Floor nozzles with a central web in the middle of the suction mouth also have this disadvantage.
  • An object of the present invention is accordingly to provide an additional embodiment of a floor nozzle, in particular a floor nozzle, with which an increase in the dust absorption effectiveness and / or a constant or at least substantially constant movement resistance can be achieved despite the increased dust absorption effectiveness.
  • a floor nozzle for a vacuum cleaner which has a suction mouth emanating from or adjoining a suction channel or a suction opening and wherein the suction mouth is limited by a suction mouth edge in at least one normal direction of movement of the floor nozzle
  • the floor nozzle is positioned in front of the suction mouth edge, and although at least in the direction of movement of the floor nozzle in front of the suction mouth edge, has at least one agitator that is movable and acting on a respective subsurface due to its mobility, and that the suction mouth edge acts as a first air guide edge and that a second air guide edge is located in front of the suction mouth edge and in front of the agitator, with between there is a distance between a height level of the first air guide edge and a height level of the second air guide edge.
  • the direction of movement or the usual direction of movement is understood here and in the following to be a forward movement of the floor nozzle during use, with a reverse movement in the opposite direction being of course also possible.
  • a forward movement a first side of the suction channel, that is to say the first suction mouth edge, then the suction channel and finally a second side of the suction channel opposite the first suction mouth edge are moved over the same point to be sucked in succession.
  • the first suction mouth edge is therefore located in front of the suction channel for a user using the floor nozzle.
  • This meaning of "in front of” is used here and in the following with reference to the forward movement assumed as the usual direction of movement, when a spatial sequence of details of the floor nozzle is explained.
  • a height level is understood to mean a position which describes a distance from a plane which is defined by the lowermost air guide edge and runs parallel to the usual direction of movement and which is referred to as floor level can be.
  • the area that is spanned by the lowermost air guide edge and the point of contact of the roller on the floor or the respective subsurface can be referred to as the floor level.
  • the advantage of the invention is primarily that due to the agitator arranged in front of the suction mouth edge in the direction of movement of the floor nozzle and the second air guide edge located in front of it, the air sucked in due to the suction air flow is guided under the agitator and due to the first air guide edge adjoining the suction mouth after entering the area of the agitator flows below this or in its lower area.
  • the air that is sucked in is thus completely available for transporting dust.
  • This achieves the goal of improved dust collection efficiency.
  • the improved dust absorption efficiency results directly from the fact that the sucked in air is guided under the agitator and the resulting improved dust transport.
  • the improved effectiveness of the dust absorption means that after passing over a swept surface, it is cleaned completely or at least better than before, so that the duration of the suction process is shortened until a satisfactory suction result is achieved.
  • the vacuum cleaner is thus in operation for an overall shorter time, so that the electrical energy used to operate the vacuum cleaner is better utilized. If the vacuum cleaner is in operation for a shorter time than previously required to achieve a satisfactory vacuuming result, this also means relief for the user, because moving the floor nozzle to and fro is accordingly only required for a shorter period of time, so that results in a time saving for the user and overall less effort due to the shortened period of use.
  • both air guide edges and especially the first air guide edge which also forms the suction mouth edge, have the property that they slightly bend up carpet fibers or other pile in the direction of movement of the floor nozzle, so that a small gap is formed directly behind the respective edge. This is where the sucked in air, which flows under the edge, comes into contact with the dust and carries it away with it.
  • the fact that the agitator is located between the two air guide edges and, due to its mobility, causes additional mechanical loosening of dust adhering to the carpet fibers, a correspondingly improved dust absorption efficiency can be achieved.
  • Values in the range from 0.3 to 0.8 mm have proven to be favorable values with regard to a distance between a height level of the first air guide edge and a height level of the second air guide edge. This ensures that with an average pile height and a normal penetration depth of a floor profile of the floor nozzle with the at least one suction channel formed there and the air guiding edges, the second, further air guiding edge also still roams through the carpet pile.
  • agitator different embodiments come into consideration, e.g. B. a movable and due to its mobility on the respective substrate, z. B. a pile carpet, acting lip as an agitator.
  • a lip instead of one lip, several lips can also be provided. So that the lip acts on the respective subsurface due to its mobility, it can be provided that the lip is under the influence of spring force.
  • Such a spring force influence can be, for. B. result with a movable molding of the lip on an underside of the floor nozzle by z. B. a provided web on the one hand ensures mobility and on the other hand acts as a spring element.
  • An alternative or additional possibility for implementing an agitator that acts on the respective subsurface due to its mobility consists in a roller with radial positions distributed in the circumferential direction.
  • a particular embodiment of such a roller is a so-called bristle roller, in particular a bristle roller, in which the radial positions in the form of bristles run helically in the longitudinal direction of the roller.
  • the or every second further air guide edge is set back, i.e. has a greater distance from the floor level, it can be achieved that a pushing force to be applied to move the floor nozzle over a pile carpet, for example, is not or at least not possible not noticeably increased. This also has the effect of reducing the resistance to movement of the floor nozzle.
  • the agitator e.g. B. a lip, a roller, a bristle roller, etc.
  • the agitator located in a recess provided for this purpose and delimited transversely to the agitator by the first and second air guide edge in an underside of the floor nozzle and the recess is laterally closed, it is ensured that the sucked in air is completely or essentially completely available for dust transport.
  • the air sucked in due to the suction air flow generated by the vacuum cleaner flows only or essentially only transversely to the respective agitator and below the agitator or in its lower area in the direction of the suction mouth.
  • the improved dust absorption efficiency can be achieved as described above and below, for both directions of movement the floor nozzle, namely away from the user and towards the user.
  • the effectiveness of the dust absorption can be increased particularly well if the floor nozzle has means for driving both agitators in opposite directions and in each case directed towards the suction mouth, in particular for rollers or bristle rollers as agitators.
  • a transmission driving both agitators in particular a transmission driving both agitators at the same time, can be considered as such a means for driving in opposite directions. Due to the counter-rotating and directed to the suction mouth drive of z. B. two rollers or bristle rollers as agitators, these not only cause a loosening of dust adhering to the carpet pile fibers, but at the same time also a transport of so loosened dust in the direction of the suction mouth.
  • An alternative embodiment of a floor nozzle is characterized by means for sensing a tensile or compressive force acting on the floor nozzle, in particular a tensile or compressive force sensor as such a means, and a clutch that can be controlled by the means or means, the clutch for activating precisely one of the both agitators is effective depending on the result of the sensing.
  • a signal can be generated with regard to a respective momentary direction of movement of the floor nozzle.
  • precisely that agitator can always be activated in which the dust transport caused by its direction of rotation is supplemented by the direction of movement of the floor nozzle.
  • one of the two agitators is always in motion, that is to say in each case a roller or bristle roller as an agitator namely the roller that is activated due to the sensed tensile or compressive force.
  • that roller or bristle roller is always activated which on the one hand for the mechanical loosening of dust adhering to the carpet pile fibers and at the same time, if the direction of movement of the floor nozzle is observed, best for transporting the loosened dust in the direction of the suction mouth is effective.
  • a forward movement i.e.
  • roller / bristle roller which is located in front of the suction mouth in this direction of movement.
