Definitions

  • the invention relates to a robot vacuum according to the preamble of claim 1.
  • the vacuum robot within the meaning of the present application is suitable for the autonomous cleaning of floor surfaces in a room.
  • the robotic vacuum cleaner includes a housing in which a suction fan for generating a suction air flow and a dirt container or a dust bag for collecting dirt particles are arranged.
  • the vacuum robot has a suction mouth, which is arranged on the housing and extends transversely to the direction of travel of the housing. This suction mouth is fluidically connected to the suction fan by means of a suction channel.
  • dirt particles located on the floor surface can be picked up from the floor surface by means of the suction air flow at the suction mouth and conveyed by means of the suction channel to the dirt container or the dust bag.
  • the floor surfaces of a room are contaminated as a result of a deposit of various types of dirt particles.
  • This usually includes fine dust, such as sand or the finest particles, and coarse dirt, such as crumbs or stones.
  • the resulting requirements for the cleaning performance of a vacuum robot are sometimes in conflict with one another.
  • robot vacuums which have a comparatively low power consumption, it is therefore often necessary to arrange the vacuum unit of the robot at the smallest possible distance from a floor surface. This achieves a special tightness between the suction unit of the vacuum robot and the floor covering.
  • the suction mechanism of a vacuum robot usually includes a suction mouth and a rotatable brush, which is arranged inside the suction mouth of the vacuum robot.
  • the high degree of tightness between the suction unit and the floor covering ensures efficient use of the suction air flow generated by the suction fan, which means that the absorption of fine dust by the suction air flow is optimally used.
  • a large inlet opening results in a reduction in the suction air flow in the area of the inlet opening, which leads to a reduced intake of fine dust by the vacuum robot.
  • Robot vacuums of the type described above are known in the prior art.
  • the known vacuum robots usually have a small distance to the one to be cleaned floor surface. Although this enables fine dust to be picked up, the simultaneous picking up of coarse dirt has proven to be problematic.
  • the DE 10 2014 103 686 A1 discloses a robot vacuum with a first suction mouth for coarse dirt in which a main brush is arranged and a second suction mouth for fine dirt in which an auxiliary brush is arranged.
  • the DE 11 2012 001 933 T5 discloses a robot vacuum with a suction mouth in which an auxiliary brush and a main brush are arranged.
  • the WO 2017 / 070492 A1 discloses a suction nozzle with an auxiliary brush and a main brush, wherein the plane of action of the auxiliary brush is arranged vertically below the plane of action of the main brush.
  • the robot vacuum cleaner according to the invention is characterized by an auxiliary brush which - viewed against the direction of travel of the robot vacuum cleaner - is located in front of the main brush and extends parallel to the main brush, with the auxiliary brush being arranged relative to the main brush in such a way that a horizontal effective plane of the auxiliary brush is up to which a brush element of the auxiliary brush extends as far as possible downwards, is arranged vertically above a horizontal effective plane of the main brush up to which a brush element of the main brush extends as far as possible downwards, so that the effective planes are arranged at a distance from one another.
  • the vacuum robot according to the invention has a suction mechanism which has a suction mouth, a main brush, an auxiliary brush and a sealing lamella.
  • the horizontal planes of action of the main brush and the auxiliary roller can also lie on a common plane.
  • an effective plane is understood to mean that horizontal plane within which dirt particles can be picked up by the brush elements of the main brush or the auxiliary brush.
  • the vacuum robot according to the invention has many advantages.
  • the arrangement of the effective planes of the main brush and the auxiliary brush at a distance from one another allows different types of dirt particles to be picked up.
  • the auxiliary brush which is upstream of the main brush, is primarily used to seal the suction unit and to pick up coarse dirt, while the main brush is primarily used to transport the fine dust lying on a floor surface and coarse dirt to the dirt container or dust bag is used.
  • the distance between the brush elements of the main brush and the floor surface to be cleaned is so small that, on the one hand, the fine dust and coarse dirt can be picked up and, on the other hand, the fine dust and coarse dirt are conveyed through the suction channel into the dirt container or dirt bag with the additional effect of the suction air flow.
  • an arrangement of the main brush in such a way that the effective plane of the main brush coincides with the floor surface.
  • the effective plane of the auxiliary brush is arranged at a greater distance from the floor surface.
  • the distance is selected in such a way that the suction unit is sufficiently tight to the floor surface of the room, which ensures that the suction air flow generated by the suction fan can be used efficiently on the suction unit and thereby counteracts a reduction in the cleaning effect of the vacuum robot.
  • the auxiliary brush is preferably designed in such a way that it can transport the coarse dirt to the main brush. Provision is preferably made for the coarse dirt and the fine dust to be conveyed from the auxiliary brush to the main brush by the effect of the suction air flow during operation of the robotic vacuum cleaner.
  • the latter transports the dirt particles to a dirt container or dust bag with the additional effect of the suction air flow.
  • the suction unit can be sufficiently tightly sealed relative to the floor surface to be cleaned.
  • the robotic vacuum cleaner according to the invention can thus achieve a cleaning effect even in the case of low power consumption, in which different types of dirt particles are picked up equally from the floor surface.
  • the lengths of the main brush and the auxiliary brush are advantageously at least substantially, preferably exactly, the same.
  • the distance between the effective planes is at most 5 mm, preferably at most 3 mm, more preferably at most 1.5 mm. It has been found that such an arrangement of the effective planes is particularly advantageous, in particular with regard to sufficient sealing of the vacuum robot on the one hand and the effect of the suction air flow in the area of the suction mechanism of the vacuum robot on the other.
  • An advantageous embodiment of the invention provides that at least one brush element, preferably all brush elements, of the auxiliary brush have a smaller radial length in relation to a brush body of the auxiliary brush than at least one brush element, preferably all brush elements, of the main brush in relation to a brush body of the main brush.
  • the plane of action of the main brush as well as that of the auxiliary brush is determined on the one hand by the respective distance of the respective brush body from the floor surface to be cleaned and on the other hand determined by the radial length of the respective brush element.
  • a lower limit with regard to the size of the dirt particles to be picked up by the respective brush can thus advantageously be adjusted by varying the distance between the respective brush body and the floor surface and by changing the radial length of the respective brush element.
  • both the brush body of the main brush and that of the auxiliary brush are arranged at a common distance from the floor surface on the housing.
  • the distance between the effective planes of the same can then be adjusted by adjusting the radial length of the brush elements.
  • the radial length of the brush elements of the main brush and that of the auxiliary brush match and the distance between the effective planes can be adjusted by means of the distance between the respective brush body and the floor surface to be cleaned.
  • an outer diameter of the auxiliary brush is smaller than an outer diameter of the main brush. It is preferably provided that the outer diameter of the main brush is between 30 mm and 50 mm, preferably between 35 mm and 45 mm, more preferably between 38 mm and 42 mm. On the other hand, an outer diameter of the auxiliary brush is preferably between 15 mm and 40 mm, preferably between 18 mm and 27 mm, more preferably between 20 mm and 25 mm. The outer diameter of the respective brush is determined on the one hand by a diameter of the respective brush core and by the radial length of the respective brush elements.
  • auxiliary brush has a plurality of brush elements which are preferably distributed equidistantly over a circumference of the associated brush body. This can advantageously result in improved and faster cleaning of the floor surface.
  • the at least one brush element of the auxiliary brush is formed from a flexible plastic, in particular in the form of a rubber lamella. It has been found that forming the brush element of the auxiliary brush from a flexible plastic is particularly advantageous with regard to picking up the coarse dirt and transporting the dirt particles in the direction of the main brush. In particular, such a design enables a deformation of the brush element.
  • the brush element can thus advantageously adapt particularly well to a shape of the dirt particle to be picked up, as a result of which the cleaning effect of the robotic vacuum cleaner is additionally improved.
  • a flexible brush element ensures that the suction unit is adequately sealed against the floor surface.
  • the at least one Brush element of the auxiliary brush formed by a flexible plastic in the form of tufts of bristles.
  • the brush elements of the auxiliary brush are formed by at least one tuft of bristles and at least one rubber lamella.
  • a further embodiment of the invention provides that the at least one brush element of the main brush, preferably a multiplicity of brush elements of the main brush, are formed by tufts of bristles. This further increases the cleaning effect of the vacuum robot. It is preferably provided that the respective brush element is formed from a large number of filaments which are combined to form a brush element. It is conceivable that the filaments are formed from a flexible plastic in order to enable the tufts of bristles to be adapted to the respective floor surface and to the dirt particles to be picked up.
  • the at least one brush element of the main brush is formed by a rubber lamella.
  • the brush elements of the main brush are formed by at least one rubber lamella and at least one tuft of bristles.
  • the auxiliary brush can be driven in rotation, with the main brush and the auxiliary brush preferably being able to be driven in the same direction of rotation.
  • the cleaning effect of the vacuum robot can be further increased in this way.
  • the dirt particles are transported better to the dirt container or dust bag of the robotic vacuum cleaner.
  • the transfer of the coarse dirt, which is preferably caught first by the auxiliary brush, to the main brush is improved by means of the rotary movement of the auxiliary brush.
  • An advantageous embodiment of the invention provides that the auxiliary brush and/or the main brush can be driven as a function of a driving speed of the vacuum robot. If the driving speed of the robot vacuum is increased while the speed of the auxiliary brush and/or the main brush remains the same, the number of times the auxiliary brush and/or the main brush scrape the floor surface is reduced in relation to the distance traveled by the robot vacuum. By adjusting the speed of the auxiliary brush and/or the main brush, a constant cleaning effect of the robotic vacuum cleaner can be achieved over the entire operation, regardless of the driving speed. It is preferably provided here that the rotational movement is also increased when the driving speed increases and is reduced when the driving speed decreases.
  • the main brush as well as the auxiliary brush are driven by a drive which is operatively connected both to the main brush and to the auxiliary brush.
  • a drive which is operatively connected both to the main brush and to the auxiliary brush.
  • a further embodiment of the invention provides for a sealing lamella arranged behind the main brush--viewed against the direction of travel of the vacuum robot--whose effective plane preferably coincides with the effective plane of the main brush.
  • the sealing lamella fulfills two functions: on the one hand, the sealing lamella achieves a tight seal between the suction unit and the floor surface in a rear area of the vacuum robot, which means that the suction air flow is not weakened and the cleaning effect is thus ensured.
  • the sealing lamella acts in the manner of a dust pan. The sealing lamella does not push dirt particles picked up by the auxiliary brush or the main brush in front of it, which are then conveyed to the dirt container by the effect of the suction air flow in the area of the main brush. Provision is preferably made for the sealing lamella and the main brush to rest on the floor surface and thus ensure that the suction mechanism of the robotic vacuum cleaner is adequately sealed.
  • the sealing lamella is formed from a flexible plastic, in particular from a rubber lamella.
  • the sealing lamella can thus advantageously adapt to unevenness in the floor surface. Furthermore, this prevents damage to the floor surface, which would occur, for example, if the sealing lamella were formed in the form of a metal.
  • the sealing lamella is inclined, preferably at an angle in the range between 25° and 65°, more preferably at an angle of 45°, relative to the vertical.
  • the sweeping function of the same is additionally increased. It has been found that when the sealing lamella is arranged perpendicularly to the floor surface, it tends to buckle when driving over bumps in the floor surface, in particular if the sealing lamella is made of a flexible plastic. The result is a reduction in the cleaning effect of the sealing lamella.
  • the sealing lamella is either arranged in such a way that the sealing lamella pushes the dirt particles in front of it or has such an alignment in which the dirt particles are "pulled along".
  • the cleaning effect of the sealing lamella is additionally improved and consequently results in improved cleaning of the floor surface.
  • An embodiment in the Figures 1 to 3 shown, comprises a vacuum robot 1 for autonomous cleaning of a floor surface 22 of a room 23.
  • FIG. 1 shows a vacuum robot 1 according to the prior art.
  • the robotic vacuum cleaner 1 includes a housing 2 with a round cross section.
  • a suction fan 3 for generating a suction air flow and a dirt container 4 for receiving dirt particles are arranged in the housing.
  • On an underside 24 the vacuum robot 1 also has a suction mouth 5 which is fluidically connected to the suction fan 3 by means of a suction channel 6 .
  • Also arranged on the underside 24 is a main brush 7, which is set in rotary motion by means of a drive not shown in detail in the figures.
  • the main brush 7 extends transversely to a travel direction 8 of the housing 2.
  • FIG. 1 An embodiment of a vacuum robot 1 according to the invention is in the figures 2 and 3 shown.
  • the vacuum robot 1 according to the invention has, as in figure 2 shown, also a main brush 7 on.
  • the main brush 7 is arranged on an underside 24 of the vacuum robot 1 and ends flush with the housing 2 at the side.
  • the main brush 7 is formed here from a brush body 17 and a plurality of brush elements 13 which are distributed equidistantly over a circumference of the brush body 17 .
  • the individual brush elements 13 are formed by individual tufts of bristles made of a flexible plastic.
  • the robotic vacuum cleaner 1 has an auxiliary brush 9, which figure 3 is shown.
  • This is the main brush 7, viewed against the direction of travel 8 of the vacuum robot 1, upstream.
  • the auxiliary brush 9 extends parallel to the main brush 7 and is also formed from a brush body 19 and a plurality of brush elements 11 .
  • the brush elements 11 of the auxiliary brush 9 are each in the form of a rubber lamella, consisting of a flexible plastic.
  • An outer diameter 15 of the main brush 7 is approximately 43 mm, while an outer diameter 16 of the auxiliary brush 9 is approximately 24 mm amounts to.
  • a radial length 18 of the brush element 11 of the auxiliary brush 9 in relation to the brush body 19 of the same is less than a radial length 25 of the brush element 13 of the main brush 7 on the brush body 17 of the same.
  • the main brush 7 and the auxiliary brush 9 are rotatably driven by means of a common drive on the housing and have the same direction of rotation.
  • the direction of rotation is oriented in such a way that the brush elements 11 , 13 move downwards, ie towards the floor surface 22 , as viewed from a front side of the vacuum robot 1 .
  • the robotic vacuum cleaner 1 has a sealing lamella 20 which is also arranged on an underside 24 of the housing 2 and extends over the entire width of the robotic vacuum cleaner 1 .
  • the sealing lamella 20, which figure 2 is shown here is arranged behind the main brush 7 and designed in the form of a rubber blade. In this case, the sealing lamella 20 is aligned at an angle 26 of approximately 57° with respect to a vertical on the housing 2 .
  • the main brush 7, the auxiliary brush 9 and the sealing lamella 20 each have an active plane 10, 12, 21, within which dirt particles can be picked up.
  • the plane of action 10, 12 of the main brush 7 and the auxiliary brush 9 is determined by that plane to which an associated brush element 11, 13 extends at most downwards, ie in the direction of the floor surface 22 to be cleaned.
  • the plane of action of the sealing lamella 20 is determined by that plane up to which the sealing lamella 20 itself extends as far as possible downwards.
  • the main brush 7 is mounted on the housing 2 in such a way that the brush elements 13 are placed on the floor surface 22 .
  • the plane of action 10 of the main brush 7 thus coincides with the bottom surface 22 of the space 23 .
  • the plane of action 12 of the auxiliary brush 9 is arranged at a distance 14 of about 3 mm from the plane of action 12 of the main brush 7 .
  • the housing 2 of the robotic vacuum cleaner 1 is shaped in such a way that it follows an outer contour of the auxiliary brush 9 and the main brush 7 .
  • the housing 2 of the robotic vacuum cleaner 1 is provided in a front area with an inlet opening 27 which corresponds approximately to the maximum size of the dirt particles to be picked up.
  • the effective plane 21 of the sealing lamella 20 is also arranged at a distance 29 from the bottom surface 22 .
  • the distance 29 is selected in such a way that, on the one hand, sufficient tightness is achieved in a rear area of the vacuum robot 1 and thus an effect of the suction air flow generated by the suction fan 3 is not reduced and, on the other hand, damage to the floor surface 22 is avoided.
  • dirt particles located on the floor surface 22 are conveyed in the direction of the main brush 7 in a first step as a result of the rotary movement of the auxiliary brush 9 .
  • those dirt particles are captured by the auxiliary brush 9, whose Size of the inlet opening 27 of the bottom surface 22 corresponds. This is typically coarse dirt in the form of crumbs or stones. Smaller dirt particles, in particular fine dust, are not caught by the auxiliary brush 9 when the vacuum robot 1 travels over them, but by the effect of the suction air flow at the inlet opening 27 .
  • the dirt particles transported by the auxiliary brush 9 in the direction of the main brush 7 are then caught by the main brush 7 .
  • the dirt particles are mobilized and guided to the dirt container 4 by means of the suction air flow. Dirt particles which have not been caught by either the auxiliary brush 9 or the main brush 7 or those which have not been caught directly by the suction air flow are held back by the sealing lamella 20 .
  • the sealing lamella 20 acts in the manner of a dust pan and thus enables additional absorption of the dirt particles. Furthermore, the sealing lamella 20 has a sealing effect for the rear area of the robotic vacuum cleaner 1.
