Definitions

  • the invention relates to a floor nozzle for a vacuum cleaning device, which has a housing and a suction channel arranged in the housing for connection to a fan of a vacuum cleaning device, the suction channel being displaceable by means of an actuator from a hard floor position to a carpeted floor position or vice versa.
  • the suction cleaning device can be a cleaning device designed either only for suction or for both suction and wiping. This is either hand-held by a user or can be moved automatically, for example as a cleaning robot.
  • setting the floor nozzle for a hard floor differs from a setting for a carpeted floor or carpet.
  • the settings differ, for example, by a different distance between a suction mouth connected to the suction channel and the surface to be cleaned.
  • the floor nozzle is usually positioned on the surface to be cleaned by means of sealing elements, for example bristle elements and/or sealing lips, creating or increasing a distance between the suction mouth and the surface to be cleaned. This prevents scratches in the hard floor.
  • the suction mouth is usually brought up to the surface to be cleaned, so that the distance between the suction mouth and the carpeted floor or carpet is reduced.
  • the pamphlet WO 2011/007160 A1 discloses, for example, a floor nozzle in which, depending on the type of floor covering, a bristle unit arranged on the floor nozzle is displaced, whereby at the same time the housing of the floor nozzle is lowered onto or lifted from the surface to be cleaned.
  • the bristle unit is connected to an air bellows which, in the case of a hard floor, causes the bristle unit to move out beyond the outer circumference of the housing and, in the case of a carpeted floor, causes the bristle unit to move into the housing.
  • a valve is assigned to the air bellows, which valve opens or closes depending on the type of floor covering and thus triggers an expansion or contraction of the air bellows.
  • a floor nozzle is from US4706327 known.
  • the floor nozzle is adapted to the type of floor covering by moving the suction channel relative to the housing. It is not necessary to move the housing as such in order to bring the suction channel and thus in particular the plane of the suction mouth, in which the suction channel ends at the bottom, closer to the surface to be cleaned. As a result, the shift from the hard floor position to the carpeted floor position, and vice versa, may take place with less effort.
  • the housing preferably encloses the suction channel on the top and/or on the side.
  • the suction mouth can protrude downwards beyond the housing, possibly depending on a displacement position of the suction channel.
  • a displacement of the suction channel preferably also takes place through the housing and is not visible to a user of the vacuum cleaning device.
  • the suction channel is connected to the actuator by means of a gear in such a way that the suction channel can be displaced, in particular pivoted, relative to the housing as a result of actuation of the actuator.
  • the suction channel is mounted on the housing such that it can be displaced, for example about a pivot axis which corresponds to a rotation axis of a traverse of the floor nozzle.
  • the suction channel is advantageously moved into the housing in a hard floor position, so that the suction mouth does not protrude beyond the outer contour of the housing or at least not beyond the level of a bristle unit and, for example, cannot scratch sensitive hard floor coverings.
  • the suction mouth is advantageous at least with one End area pivoted out of the housing or possibly above the level of a bristle unit, so that it rests on the carpet.
  • the displacement of the suction channel is effected by means of the actuator, the suction channel being connected to the housing in such a way that a displacement or movement of the actuator also results in a displacement of the suction channel, in particular a pivoting of the suction channel about the pivot axis.
  • the gear mechanism of the floor nozzle has a guide link which is displaceably arranged on the housing and into which an engagement element of the suction channel engages.
  • a guide link between the actuator for example an air bellows
  • the suction channel By using a guide link between the actuator, for example an air bellows, and the suction channel, the force required for pivoting, in particular for pivoting from a carpeted floor position to a hard floor position, of the suction channel can be significantly reduced.
  • the actuator required for pivoting can be smaller, for example an air bellows with a smaller diameter can be used, a servomotor with less power or the like can be used. This may in turn lead to a smaller design of the actuator, which contributes overall to the low weight and small dimensions of the floor nozzle.
  • the suction channel and the guide link are connected by means of an engagement element of the suction channel, wherein the engagement element engages in the guide link and is also displaced when the guide link is displaced relative to the housing.
  • the guide slot has a guide surface with a corresponding incline, along which the engagement element of the suction channel can slide.
  • the lifting of the suction channel from the surface to be cleaned is brought about by the restoring movement of the actuator, e.g. combined with the restoring force of a spring assigned to the actuator, in conjunction with the incline of the link, the incline continuously moving the engagement element away from the surface to be cleaned moves and thus causes a lifting of the suction channel. Since the suction channel is also pivotably mounted on the housing of the floor nozzle, the force to be overcome is reduced due to the leverage effect.
  • the guide link can be displaced essentially parallel to a surface to be cleaned, based on an orientation of the floor nozzle during normal suction operation.
  • the guide link can thus be displaced essentially horizontally, so that the force to be used to move the guide link is as small as possible.
  • the actuator thus advantageously pulls the guide link horizontally towards itself or pushes it away from itself in the horizontal direction during expansion.
  • the guide link based on a direction of displacement towards the actuator provides a sloping guide surface for the engagement element, so that the engagement element relative to a position of the floor nozzle during normal suction operation in the direction of cleaning surface is displaceable.
  • the movement of the engagement element relative to the housing of the floor nozzle is guided in such a way that the engagement element is displaced essentially perpendicularly to the surface to be cleaned, ie also essentially perpendicularly to the direction of displacement of the guide link.
  • the guide surface can be provided, for example, by a slot formed in the guide link, in which the engagement element engages.
  • the engagement element is thus connected to the guide slot on the one hand and to a guide of the housing on the other hand.
  • the object on which the invention is based is also achieved by a floor nozzle according to claim 4 .
  • the transmission has two transmission elements pivotally connected on a common pivot axis that can be displaced by means of the actuator, with a first transmission element being connected on the one hand with the pivot axis and on the other hand with the suction channel, and with a second transmission element being connected on the one hand with the pivot axis and on the other hand with the housing .
  • This configuration corresponds to the structure of a linkage.
  • the suction channel is pivotally connected to the housing and the actuator by means of the gearing.
  • the two gear elements can be pivoted about a common pivot axis, which pivot axis can be displaced at the same time by actuating the actuator.
  • the first gear element and the second gear element are pivoted relative to one another, since the second gear element is at its end region opposite the pivot axis is connected to the housing of the floor nozzle and the first gear element is connected to the suction channel at its end region remote from the pivot axis.
  • the pivot axis is shifted in the direction of the actuator, with the two gear elements being pivoted apart like scissors and the first gear element, which is connected to the suction channel, moves the suction channel in the direction of the cleaning surface swivels.
  • the actuator when the actuator is actuated from the carpeted floor position in the direction of the hard floor position, the pivot axis of the gear element is displaced away from the actuator, so that the two gear elements are pivoted towards one another about the pivot axis and the end region of the suction channel is displaced in towards the housing of the floor nozzle.
  • the actuator can also be an air bellows, a servomotor, a lifting magnet or the like.
  • the object on which the invention is based is also achieved by a floor nozzle according to claim 5 .
  • the gear is a rack and pinion gear or toothed wheel gear connected on the one hand to the suction channel and on the other hand to the actuator.
  • the actuator can be connected to a toothed rack, for example, which is connected to the suction channel via a toothed wheel or a plurality of toothed wheels and a further toothed rack.
  • the actuator can again be an air bellows, a lifting magnet, a servomotor or the like.
  • a spring is assigned to the actuator, the restoring force of which is directed in the direction of a preferred position of the suction channel, in particular in the direction of a hard floor position of the suction channel shifted into the housing.
  • the suction channel is always in a predefined position, namely the preferred position.
  • This preferred position can in principle be either the hard floor position or the carpeted floor position of the suction channel, although it is advantageous for the preferred position to be the hard floor position in which the suction channel is moved into the housing and the suction mouth therefore does not point beyond the outer contour of the housing and does so possibly damage a sensitive floor covering.
  • the floor nozzle advantageously stands on a bristle element and/or a sealing lip, so that a sufficient distance is created between the floor covering and the housing of the floor nozzle.
  • the restoring force of the spring is adapted to the structural conditions of the pivoting mechanism and the weight of the suction channel, so that if the actuator is not actuated, the suction channel can advantageously be lifted from the floor covering and moved into the housing solely by the restoring force of the spring.
  • the actuator has an air bellows.
  • This air bellows can be expanded by applying air or by evacuation are contracted, with the related suction channel being displaced, i.e. pivoted. The linear movement of the air bellows is deflected into a pivoting movement of the suction channel.
  • the actuator can also have a servomotor, a lifting magnet or the like.
  • the spring described above is advantageously assigned to the respective actuator. In the case of an air bellows, this can be, for example, a spiral spring arranged concentrically on the air bellows. In addition, however, other springs are also possible which provide sufficient spring deflection to cause the suction channel to pivot from a carpeted floor position into a hard floor position
  • the air bellows be assigned a valve, in particular a valve arranged in the suction channel, which can be actuated depending on the type of surface to be cleaned.
  • the air bellows can be pressurized with air or evacuated, so that it expands or contracts.
  • the valve is advantageously arranged in an air duct connected to a blower, in particular in the suction duct of the floor nozzle. Since the suction channel is already connected to the blower of the suction cleaning device, the air bellows can be evacuated via the suction channel when the valve is open, which leads to the air bellows contracting and thus to the suction channel being lowered onto the surface to be cleaned, which corresponds to the carpet position of the suction channel .
  • the air bellows When the valve is closed again, the air bellows is ventilated by the ambient air and advantageously expanded with the help of the restoring force of a spring assigned to the air bellows, so that the suction mouth is lifted off the surface to be cleaned, which corresponds to the hard floor position of the suction channel.
  • the valve can preferably be actuated automatically.
  • the valve has a communication connection to a control device, which actuates the valve depending on the type of surface currently to be cleaned.
  • the floor nozzle can have a floor sensor, which detects the type of surface to be cleaned and forwards the measurement result to the control device, which then controls the actuation of the valve accordingly.
  • the floor sensor can be, for example, a camera chip with the appropriate image processing software, an ultrasonic sensor, a tactile sensor, a contact switch or the like.
  • the valve is actuated depending on the measurement result. The actuation can take place mechanically or else electrically or magnetically in a particularly simple manner.
  • the actuation preferably takes place automatically, so that the user of the floor nozzle does not have to switch the valve manually.
  • the user it is also possible for the user to actuate the valve manually (for example by means of a foot switch) and thus trigger ventilation or evacuation of the air bellows.
