Definitions
- the invention relates to a robot vacuum cleaner and a cleaning station.
- the invention relates to a robot vacuum cleaner with a housing, which has a suction mouth on an underside for sucking in air and dirt particles and a suction chamber with a suction channel leaving the suction chamber for removing air and dirt particles, and a rotatable bristle roller arranged in the suction chamber for picking up Dirt particles that can be transported to the suction channel and a cleaning station for such robotic vacuum cleaners.
- a robot vacuum cleaner which has a knife which can engage in the bristle roller in order to be able to cut through elongated dirt particles such as hair by means of the knife.
- the elongated dirt particles are not cleaned off automatically.
- the cleaning is not sufficient because the bristle roller has poor absorption of elongated dirt particles and does not allow the elongated dirt particles to be completely removed. There is therefore still a need to effectively remove elongated dirt particles from a bristle roller of a robotic vacuum cleaner.
- the problem of the invention is thus to provide a robot vacuum cleaner and a cleaning station for robot vacuum cleaner which effectively remove elongated dirt particles from a bristle roller of the robot vacuum cleaner.
- the advantages that can be achieved with the invention are that the bristle roller is automatically cleaned of wrapped elongated dirt particles when the cutting wheel is set in rotation.
- the invention relates to a robot vacuum cleaner with a housing which has a suction mouth on an underside for sucking in air and dirt particles and a suction chamber with a suction channel leaving the suction chamber for removing air and dirt particles, and a rotatable bristle roller arranged in the suction chamber for picking up dirt particles , which can be transported away to the suction channel, and a cutting wheel which is designed to perform a rotary cutting function on elongated dirt particles located on the bristle roller when it is set in rotation.
- the elongated dirt particles are collected in one or more defined areas of the bristle roller and completely severed there so that they can be removed and / or sucked off.
- the elongated dirt particles picked up by the bristle roller are therefore comminuted in a defined collecting area and then cleaned off.
- the elongated dirt particles picked up by the bristle roller during the cleaning process do not get caught firmly in the bristles due to the arrangement of bristles and elastic lamellae. Rather, the elongated dirt particles on the bristle roller are transported in the axial direction of the bristle roller in the direction of the collecting area due to the transverse force components acting on the elongated dirt particles through the lamellae. In this collecting area, the elongated dirt particles can then be automatically comminuted and cleaned. This is accompanied by the aspect that cleaning performance is usually improved with stiffer bristles, which is achieved here due to the supporting effect of the adjacent lamellae.
- the elongated dirt particles are in particular fibers such as hair.
- the bristle roller body is cylindrical, preferably as a hollow cylinder, which has a roller axis which represents an axis of rotation.
- the transverse force component is a force component that acts parallel to the roller axis of the bristle roller body.
- the collecting area can be segmented, i.e. it can have a plurality of partial areas spaced apart from one another. Furthermore, the collecting area can have a cleaning point which enables the elongated dirt particles to be cleaned from the collecting area.
- the collecting area is designed in such a way that the elongated dirt particles that are collected in it during the cleaning process of the robotic vacuum cleaner can wind around it.
- the suction chamber is designed to build up a negative pressure which is generated during operation by means of a fan of the robotic vacuum cleaner.
- the suction chamber is open on an underside and has an elongated opening, namely the suction mouth.
- the robot vacuum cleaner also has a collecting container for collecting the dirt particles.

- the bristle roller body outer diameter of the bristle roller body preferably varies at the corresponding end at which the collecting area is formed. By increasing the outer diameter of the bristle roller body at the end of the bristle roller body at which the collecting area is located, it is possible, for example, to prevent the elongated dirt particles from migrating further into the lateral bearing points.
- the collecting area can be segmented. That is, it can have several separate sub-areas.
- a partial area can be formed equidistant from both ends of the bristle roller body and further partial areas at one or both ends of the bristle roller body, whereby three different collecting area partial areas are formed.
- a jacket surface of the bristle roller body in the collecting area is preferably made of a glass fiber-free plastic.
- a glass fiber-free plastic for example, as a two-component injection-molded component made of a material such as PP (polypropylene), POM (polyoxymethylene or polyacetal), PVC (polyvinyl chloride), PE (polyethylene), PC (polycarbonate) and / or ABS (acrylonitrile butadiene) Styrene copolymer).
