Definitions

  • the invention relates to a self-propelled ground care device for automated floor care, comprising a drive system for moving the floor care device over the floor surface to be maintained and a device control controlling the floor care device along a driveway, and a floor care roll containing rotatable and floor care liquid for applying the floor care liquid the floor area to be cared for.
  • Self-propelled floor cleaning devices are used for automated cleaning of floor surfaces. They are for example designed as vacuum cleaners, which are then usually referred to as vacuum robots. Furthermore, self-propelled cleaning devices for wiping a floor are known and combi devices that can clean by sucking and wiping.
  • wiping liquid is typically applied to the floor by means of a pump system via spray nozzles.
  • a pump system is expensive and only useful if a larger amount of liquid must be applied. If liquid is applied primarily for cleaning purposes, but for care purposes, it is usually sufficient to apply a smaller amount of liquid.
  • Such floor care liquids are, for example, oil or wax-containing and serve the care of hard floors such as parquet or plank floors.
  • the aforementioned floor care roller can be used.
  • the floor care roll stores the floor care liquid and releases it in small quantities, preferably while it is rotating. By rotating the roller, the floor care liquid is applied to the floor and worked into it, whereby the floor can be polished as well.
  • a floor care device can store and apply floor care liquid without the need for a complex pump system.
  • the floor care roll can also be designed to be compatible with a brush roll of a vacuum robot with respect to their outer dimensions and their storage, so that they can be easily replaced with an existing brush roll. In this way, a vacuum robot can be easily converted to the floor care device.
  • the floor care roll when the floor care roll is to be stored over a longer period, there may be an undesirable escape of the floor care liquid. Longer storage times occur, for example, before a first use, when the floor care roll is pre-filled with soil care liquid manufacturer. If the floor care roll was only partially emptied during a care operation, storage may also be provided for a longer period of time until a next use.
  • An inventive self-propelled floor care device of the type mentioned is characterized in that the floor care roller has an outer hollow roller body in which a relative to the outer roller body movable inner hollow roller body for receiving the floor care liquid is arranged, wherein the inner roller body depending on its position relative to the outer roller body is sealed so that leakage of soil care fluid from the inner roller body is prevented.
  • the floor care roller thus has two hollow roller bodies arranged one inside the other, the floor care fluid being stored in the interior of the roller body.
  • the roller bodies have a valve function: Depending on the relative position of the roller bodies to each other, escape of floor care fluid is either prevented or possible.
  • bores arranged in a lateral surface of the outer roller body may be covered on at least one side by a membrane, preferably of a synthetic material, in particular a textile material.
  • the membrane is selected so that it is impermeable to the floor care liquid at standstill of the roll body substantially. Only with a rotation of the roller body press on the Floor care liquid acting centrifugal forces through the membrane. The membrane thus becomes permeable to the soil care fluid.
  • bores arranged in a lateral surface of the outer roller body can be closed by a respective fiber plug containing preferably polyester fibers. Capillary forces of the fibers of the fiber stoppers retain the floor care liquid unless the roll body rotates.
  • the valve function is achieved in that in a lateral surface of the outer roller body and in a lateral surface of the inner roller body respectively bores are present, which are positioned in a position of the inner roller body relative to the outer roller body not congruent to each other and are positioned in a different position at least partially congruent to each other. Accordingly, only at congruent (hereinafter also referred to as aligned) holes positioned floor care fluid escape from the inner roller body.
  • the inner roller body relative to the outer roller body along its longitudinal axis slidably and / or rotatably disposed in the outer roller body to move the roller body relative to each other.
  • the inner roller body is accessible from the outside manually manually relative to the outer roller body in position variable.
  • the inner roller body to change its position with at least one outwardly projecting bearing pin, which is suitable for the rotatable mounting of the floor care roller coupled.
  • a drive for rotating the floor care roller acts on the inner roller body.
  • the inner roller body is rotatably coupled to at least one outwardly projecting bearing pin and / or an outer end face, wherein the drive acts on the bearing pin and / or the outer end face.
  • the drive torque of the floor care roll is automatically used in its rotational movement to activate the exit of the floor care liquid.
  • the inner roller body is sealed in at least one area with a pierceable sealing film.
  • a mandrel is arranged in the interior of the outer roller body, which is suitable for piercing the sealing film when the inner roller body moves.
  • the inner roller body can be glued by means of the sealing film, for example, at its edge can be securely sealed and sealed during the manufacturing process of the floor care roll. By piercing the sealing foil occurs a leakage of the floor care liquid and thus a one-time activation of the floor care roll.
  • an absorbent layer preferably a nonwoven layer
  • This layer can be formed tubular and pushed onto the outer roller body.
  • the absorbent layer can be wound in adjacent and / or superimposed webs on the outer roller body.
  • the co-rotating absorbent layer distributes the exiting soil care fluid and carries it to the ground. In addition, it serves an effective polish of the soil.
  • FIG. 1 a modified suction robot 1 as an embodiment of a floor care device is shown schematically in a partially sectioned side view.
  • the vacuum robot 1 has arranged on or in a housing 2 a drive system 3, which acts on two drive wheels 4, one arranged on each side of the vacuum robot 1.
  • the drive wheels 4 can be driven independently of one another via drive motors of the drive system 3 which are not shown separately here.
  • a support wheel 5 is provided, which is either pivotable or as a rotatable ball in all directions is trained. With independent control of the direction of rotation and / or rotational speed of the drive wheels 4, the vacuum robot 1 can perform movements with independently adjustable rotational and translational speeds on a floor surface to be maintained.
  • a suction mouth 6 is arranged, which is connected in a known manner with a dust cassette 7 and a suction fan 8.
  • a filter system e.g. with a vacuum cleaner bag arranged.
  • the vacuum robot 1 is controlled by a device control, not shown here, which comprises one or more microcontrollers.
  • the device control controls the individual components of the vacuum robot 1, such as e.g. the drive system 3 or the suction fan 8.
  • the device control on a navigation system that plans a guideway of the vacuum robot 1 and causes the route is traveled.
  • a navigation system that plans a guideway of the vacuum robot 1 and causes the route is traveled.

  • the floor care roller 10, hereinafter also referred to as care roller 10, is arranged in the region of the suction mouth 6. It extends substantially over the entire width of the suction mouth 6 and thus also of the vacuum robot 1. If the illustrated vacuum robot 1 used in unmodified form for cleaning a bottom surface, instead of the care roller 10, a brush roller can be arranged. This is rotated by vacuum robot 1 via drive motors and brushes dust and dirt particles with radially projecting bristles in the region of the suction mouth 6, for example, from the fibers of a carpet, so that they can be easily sucked into the suction 6.
  • the brushing roller is exchanged for the care roller 10 shown, which can also be set in rotation by the vacuum robot 1.
  • a change between the use of the vacuum robot 1 as a floor cleaning device and as a floor care device can be done quickly and easily by replacing the brush roller or care roller 10 accordingly.
  • the change between the brushing roller and care roller 10 can also be made automated by, for example, in the area of a charging station of the Vacuum robot 1 is a storage and recording option for the brushing roller or the care roller 10 is provided so that the vacuum robot 1 can replace them independently.
