Definitions

  • the invention relates to a suction robot for the autonomous cleaning of floor surfaces, wherein the suction robot has a suction mouth, wherein the suction mouth is bounded by a suction mouth lip, the suction mouth lip having a first Saugmundlippen Suite, a second Saugmundlippen Scheme and a third Saugmundlippen Suite, wherein the first Saugmundlippen Scheme with the suction robot wherein the third suction mouth lip region is configured to contact a bottom surface to be cleaned, the second suction mouth lip region connecting the first suction mouth lip region to the third suction mouth lip region, the second suction mouth lip region being formed around the suction mouth lip about an axis transverse to the direction of movement of the robotic vacuum cleaner to pivot.
  • Suction robots are known from the prior art, which have a rubber lip or strip brush to improve the mobilization of dust and dirt particles from a floor surface to be cleaned.
  • the problem here is that these rubber lips or strip brushes must be for satisfactory dust and dirt mobilization with the greatest possible force in engagement with the floor to be cleaned.
  • the exercise of a large force, especially on high pile carpet results in a resistance.
  • an excessive force on vacuum robots with the known lips or brushes leads to undesirable scratching or grinding noise or even damage to the floor surface.
  • DE 10 2014 117 418 A1 a floor nozzle for a conventional, hand-held vacuum cleaner is known, which has a movable suction lip.
  • the third suction mouth lip area in a preferred embodiment has a hardness between 85 and 99 Shore A and in a particularly preferred embodiment a hardness between 90 and 95 Shore A.
  • the preferred Shore hardness is a material characteristic according to the standards DIN EN ISO 868 and DIN ISO 7619-1.
  • the suction mouth of a vacuum robot is an opening in the Housing over which dust and dirt particles can be absorbed by the floor surface to be cleaned.
  • the suction mouth lip defines the suction mouth of the suction robot in such a way that the suction mouth lip is arranged in front of and behind the suction mouth of the suction robot with respect to the direction of movement of the suction robot.
  • the suction lip only on one side of the suction mouth.
  • the suction lip seals the suction mouth of the vacuum robot as far as possible from the environment.
  • the direction of movement of the vacuum robot is the direction in which the vacuum robot predominantly moves during the cleaning operation.
  • the suction mouth lip is pivotable about an axis running transversely to the direction of movement, so that the resistance which arises at the suction mouth lip opposite to the direction of movement of the suction robot is reduced.
  • the movement of the suction mouth lip about an axis extending transversely to the direction of movement of the vacuum robot is justified by objects which are located on the floor surface to be cleaned and are in contact with the suction mouth lip.
  • the third suction mouth lip region of the suction mouth lip is designed in such a way that it contacts the floor surface to be cleaned during the cleaning operation of the suction robot.
  • the vacuum robot moves autonomously over a floor surface to be cleaned and cleans it of dust and dirt particles.
  • the second suction mouth lip region has a hardness between 40 to 65 Shore A and in a particularly preferred embodiment a hardness between 45 to 60 Shore A.
  • the first suction mouth lip region in a preferred embodiment has a hardness between 85 to 99 Shore A and in a particularly preferred embodiment a hardness between 90 to 95 Shore A.
  • a Saugmundlippe in the preferred hardnesses ensures adequate mobilization of dust and dirt particles without causing disturbing noises or causing damage to the bottom surface.
  • a suction mouth lip in the preferred hardnesses is capable of bending the fibers of carpeting sufficiently without resulting in a seizure of the vacuum robot due to the resulting resistances.
  • the suction mouth is delimited by a second suction mouth lip, wherein a first suction mouth lip is arranged in front of the suction mouth and a second suction mouth lip behind the suction mouth.
  • the sides of the suction mouth which are oriented essentially transversely to the direction of movement of the suction robot, are delimited by a first and a second suction mouth lip.
  • a movable suction lip according to the invention only on one side in front of or behind the suction mouth. On the corresponding side of the suction mouth, an approximately rigid suction mouth lip or no suction mouth lip is arranged in this alternative embodiment.
  • suction lips in front of and behind the suction mouth with respect to the direction of movement of the vacuum robot causes sufficient sealing of the suction mouth from the environment. This ensures a satisfactory mobilization and absorption of dust and dirt particles by the vacuum robot.
  • the first suction mouth lip region is detachably connectable to the suction robot.
  • the suction mouth lip is detachably connectable to the suction robot via the first suction mouth lip region.
  • the suction mouth lip with the first suction mouth lip region is arranged in a suction mouth module which is arranged detachably on the suction robot.
  • the detachable arrangement of the suction lip on the vacuum robot allows a regular replacement. If any wear of the suction lip in cleaning operation, especially on the third Saugmundlippen Scheme, the suction lip can also be easily changed by the user. This ensures a consistent cleaning performance of the robotic vacuum cleaner along its entire product life cycle.
  • the suction lip be produced in a multi-component injection molding process. This ensures the production of the suction lip with individual Saugmundlippen Suiteen from different material components or materials with different material properties.
  • the production of the suction lip by a multi-component injection molding process is cost-minimized and allows the configuration of a suction lip with optimal properties for use in vacuum robots.
  • FIG. 1 shows the sectional view of the suction mouth of a vacuum robot 10 with two suction mouth lips 14.
  • the drawn arrow represents the direction of movement 22 of the vacuum robot 10.
  • This movement direction 22 follows the vacuum robot 10 in the cleaning mode mainly.
  • the housing 28 of the vacuum robot 10 impresses a Suction mouth 12, with which the vacuum robot 10 receives dust and dirt particles from the floor surface to be cleaned.
  • a fan (not shown in FIG FIG. 1 ), which generates a suction air flow. This suction air stream is used for mobilization and removal of dust and dirt particles from the carpet 30 to be cleaned.
  • a suction mouth lip 14 is detachably arranged on the housing 28 of the vacuum robot 10. Both suction mouth lips 14 protrude from the housing 28 in the direction of the carpet 30 to be cleaned. Both suction mouth lips 14 define a first 16, a second 18 and a third suction mouth lip region 20.
  • the first suction mouth lip region 16 is arranged in a form-fitting manner in the housing 28 of the suction robot 10.
  • the third suction mouth lip region 20 is in engagement with the carpet fibers of the carpet 30 to be cleaned.
  • the second suction mouth lip region 18 connects the first 16 and third suction mouth lip regions 20.
  • Both suction mouth lips 14 cause a bending of the carpet fibers of the carpet to be cleaned 30.
  • dust and dirt particles (not shown in FIG. 1 ), which have accumulated between the individual carpet fibers, improved transported by the suction air flow of the vacuum robot 10.
  • the movement of the carpet fibers, which is caused by the suction mouth lips 14, leads to a partial whirling up of dust and dirt particles. This causes an additional improvement of the cleaning performance of the vacuum robot 10.
  • the carpet fibers have a too low rigidity in order to effect a deflection of the suction mouth lips 14.
  • FIG. 2 also shows a sectional view of the suction mouth 12 of a vacuum robot 10 with two suction mouth lips 14.
  • the carpet to be cleaned 30 defines an edge 32, which is to be run over by the vacuum robot 10.
  • the third suction mouth lip region 20 is in contact with the edge 32.
  • This pivoting movement is made possible by the second suction mouth lip region 18 kinked about an axis which is transverse to the direction of movement 22 of the vacuum robot 10.
  • the pivoting movement of the third suction mouth lip region 20 increases the distance of the third suction mouth lip region 20 from the carpet 30 and thus allows the third suction mouth lip region 20 to slide over the edge 32 on the carpet 30. Firming of the suction robot 10 by contact between the suction lip 14 and the edge 32 is thereby prevented.
