Definitions

  • the invention relates to a sweeper for cleaning carpets and hard floors, comprising a housing, a dirt collecting container which has a dirt inlet opening, and a brush roller which can be rotated and is arranged adjacent to the dirt inlet opening, a brushing threshold being assigned to the brush roller at the dirt inlet opening, via which dirt particles in the dirt collection container can be transferred.
  • Such sweepers allow cleaning of both carpets and hard floors. Dirt particles can be picked up by the brush roller and thrown into the dirt collecting container via the sweeping threshold.
  • the sweeping edge should be as close as possible to the floor surface to be cleaned, so that it can be prevented that the dirt particles caught by the brush roller are thrown under the sweeping edge.
  • the object of the present invention is to develop a sweeper of the generic type in such a way that the forward movement of the sweeper is prevented by the sweeping threshold.
  • This object is achieved according to the invention in a sweeper of the type mentioned at the outset in that the sweeping threshold is held on the housing so as to be adjustable in the direction of the floor surface to be cleaned.
  • the sweeping threshold can thus be adjusted in its distance from the floor surface, so that jamming of the sweeping threshold, for example with a carpet, can be reliably prevented by correspondingly positioning the sweeping threshold above the carpet.
  • the threshold is adjustable on the housing. This enables, in particular, an embodiment in which the sweeping threshold is arranged to be movable relative to the brush roller, so that when cleaning a carpeted floor the brush roller sinks somewhat into the carpet, but the sweeping threshold slides over the fibers of the carpet.
  • An actuator is preferably assigned to the threshold for positioning the threshold at a minimum distance from the floor surface when the housing is approaching the floor surface.
  • the threshold can be independent of the nature of the floor surface, i.e. both when cleaning a relatively soft carpet and a hard floor , be kept at a minimum distance from the floor.
  • the actuator has mechanical contact elements which contact the floor surface when the minimum distance between the bump threshold and the floor surface is undershot and keep the bump threshold at a distance from the floor surface.
  • the minimum distance is preferably approximately 0.3 to approximately 0.7 mm, in particular approximately 0.5 mm.
  • the contact elements can, for example, be designed as freely rotatable contact rollers mounted on the bump. In a particularly preferred embodiment, it is provided that the contact elements are designed as sliding skids that slide along the bottom surface when the minimum distance between the threshold and bottom surface is undershot.
  • the sweeper is designed to be movable and includes drive wheels and / or support rollers, the skids being held relative to the floor surface to be cleaned above the peripheral region of the drive wheels and / or support rollers contacting the floor surface.
  • the skids are spaced from the floor surface when cleaning a hard floor, but slide along the carpet when cleaning a carpet, while the drive wheels and / or support rollers sink somewhat into the carpet due to the weight of the sweeper.
  • a guide can be used for the adjustable mounting of the bump on which the bump is slidably held.
  • the sweeping threshold can be pivoted about a pivot axis aligned parallel to the axis of rotation of the brush roller.
  • the sweeping threshold can be held on at least one pivoting pivot arm, which is preferably articulated on the rigid housing.
  • the mechanical contact elements explained above are preferably held on the swivel arm. It is advantageous if the contact elements are integrally connected to the swivel arm. For this purpose, it is advantageous if the swivel arm falls below one a minimum distance between the threshold and the floor surface has the sliding surface contacting the floor surface.
  • the sliding surface of the swivel arm projects beyond the sweeping threshold in the direction of the floor surface.
  • the protrusion of the sliding surface ensures that the sweeping threshold is kept at a distance from the floor surface even when cleaning a carpet, since the sliding surface slides along the carpet and the sweeping threshold is set back in relation to the sliding surface in the direction facing the floor surface.
  • the sweeping device has two pivotably mounted swivel arms, at the free ends of which the sweeping threshold is held. It is advantageous if the two swivel arms are arranged outside the dirt inlet opening, for example, to accommodate the dirt inlet opening between them. Such a positioning of the swivel arms has the consequence that the dirt inlet opening has a geometry that is not influenced by the position of the swivel arms and consequently the shape of the dirt inlet opening is independent of the position of the swivel arms.
  • the bump threshold is elastically prestressed in the direction of the floor surface by means of a spring element.
  • the sweeping threshold can be adjusted against the action of an elastic restoring force in the direction of the housing of the sweeping device. but it is ensured that the sweeping threshold assumes a defined position relative to the housing in the absence of external forces.
  • a leaf spring or a spiral spring can be used as the spring element. It has proven to be particularly favorable if the spring element is made from a rubber-like material, preferably from an elastomer.
  • the spring element is advantageously held on the dirt collecting container, which is preferably rigidly connected to the housing.
  • the spring element forms a flexible seal which is arranged between the sweeping threshold and the dirt collecting container. This enables a dust-tight closure of the dirt collecting container in the area of the adjustable sweeping threshold. It can be provided here that the seal forms at least one sealing lip which can be placed on a wall of the dirt collecting container.
  • the sweeping device is designed as a sweeping suction device and, for this purpose, has a suction turbine which is in flow connection via a suction channel with the dirt collecting container and the dirt inlet opening.
  • a suction flow can be generated by means of the suction turbine, which supports the transfer of the dirt particles from the dirt inlet opening into the dirt collecting container.
  • a dirt filter is arranged in the suction duct and the suction duct forms the dirt collecting container upstream of the dirt filter. This enables a special compact design of the sweeper, since a separate dirt collecting container is not absolutely necessary.
  • the sweeper is designed to be movable, the dirt inlet opening facing the floor surface to be cleaned being arranged in a front region of the sweeper in the direction of travel, while the suction turbine is positioned in an end region of the sweeper rearward in relation to the direction of travel, and that the Suction channel is aligned substantially horizontally and connects the suction inlet opening with an inlet opening of the suction turbine.
  • the suction channel can comprise holding means for holding the dirt filter, so that a region of the suction channel which extends upstream of the holding means and the dirt filter forms the dirt collecting container.
  • the suction channel comprises a base plate which is detachably connected to the housing and on which the sweeping threshold is held.
  • the base plate provides access to the suction channel for changing the dirt filter and, if necessary, for emptying the dirt collecting container.
  • the brush roller can be driven by means of an electric motor, the electric motor preferably being connected to a rechargeable voltage source. is closable. In order to limit the power consumption of the electric motor when cleaning a carpet, in particular, it is advantageous if the contact pressure of the brush roller on the floor surface to be cleaned can be controlled.
  • the brush roller is held on the housing so as to be adjustable in the direction of the bottom surface, the adjustment of the position of the brush roller being independent of the adjustment of the position of the sweeping roller.

  • the brush roller can, for example, be slidably held on the housing by means of guide elements aligned obliquely or parallel to the vertical.
  • the brush roller is mounted on the housing on a pivoting member so as to be pivotable about a pivot axis aligned parallel to the axis of rotation of the brush roller.
