Definitions

  • the present invention relates to an autonomous cleaner.
  • Autonomous cleaners have a cleaner body which comprises the different components of the cleaner, and wheels supporting the body to make it possible for the cleaner to move over the floor surface.
  • electrical motors are arranged together with at least two wheels for powering the cleaner.
  • Particles such as dust, sand etc are collected from the floor surface by a brush roll and lead via a passage adjacent to the roll to a dust container arranged within the body.
  • the roll could be combined with a fan powered by an electric motor to generate a flow of air through the passage to suck the particles into the passage and the dust container.
  • the disclosed cleaner has a substantially circular cleaner body comprising the different components of the cleaner.
  • a number of different components are fitted within the cleaner body which in combination with the desired small outer size of the cleaner makes the room for the different components limited.
  • the limited space within the cleaner body has some severe drawbacks on the disclosed cleaner.
  • One of them is that the dust container has a very small volume. The small volume results in that the container must be emptied more frequently to ensure the desired cleaning result which is devastating since the container must be emptied manually.
  • the removal and fitting of the dust container in the cleaner body is complicated due to the complex design of the dust container and the surrounding structures in the cleaner body.
  • JP2009 500741 A discloses a robotic cleaning device having a main body with a controllable drive means to move the device over a surface, a cleaning means to clean the surface, an obstacle detecting means, and a control means connected to the drive means and the obstacle detecting means.
  • the main body has a left wall connecting a front end portion with a left rear end portion and a right wall connecting the front end portion with a right rear end portion.
  • the cleaning device removes dust from the surface to be cleaned through a suction slit positioned in the rear part of the main body which can make it difficult to pick up dust in for example corners.
  • WO 03/024292 discloses relates to an automatically displaceable floor-type dust collector comprising at least one electro-motive drive, a dust collector container and a covering hood.
  • the basic shape of the device deviates from that of a circle.
  • the basic shape thereof consists of a circular section and a shaped section tending to the rectangular.
  • the rectangular section is disposed upstream in the direction of displacement.
  • the present invention relates to an autonomous cleaner that to at least some extent fulfils the needs defined above.
  • the autonomous cleaner according to the invention comprises:
  • the dust compartment volume is defined as the volume within the dust container usable for particles, debris and dust, and the volume of the cleaner body the volume within the cleaner body with the volume of the dust container included in the cleaner body volume.
  • the cleaner according to the invention provides an efficient autonomous cleaner that is able to cover large floor areas without requiring emptying of the dust container since the volume of the dust container in relation to the volume within the cleaner body is larger than in known cleaners.
  • the increased dust container volume is a result of extensive work to optimize the different components arranged in the cleaner body and the internal configuration and layout of the different components required to ensure that the autonomous cleaner work as intended.
  • the dust container furthermore comprises a container wall and a filter arranged in the dust container, wherein the dust compartment within the dust container is defined by the container wall and the filter.
  • the filter together with the container wall, defines the dust compartment, i.e. the dust compartment usable for debris received in the dust container.
  • the cleaner body is surrounded by a casing and the volume of the cleaner body defined by the casing is within the range 4 to 6 litres.
  • the casing protects the different components arranged in the cleaner body and the specified volume ensures a cleaner body with limited outer dimensions which makes it easier for the cleaner to clean areas that otherwise would have been difficult to access.
  • the dust container comprises a surface arranged to constitute a part of the cleaner casing to reduce the number of different components and/or different constructional elements within the cleaner body and thereby make it possible to increase the dust container volume within the cleaner body.
  • the inlet is arranged in a first side and the outlet is arranged in a second side of the dust container, said filter is arranged to extend across the entire dust container between the inlet and the outlet and the volume of the dust compartment on the inlet side of the filter is at least 0,6 liters.
  • the defined container design with the filter in the dust container is favourable since the flow of air through the dust container will extend through the filter.
  • This embodiment furthermore makes it possible to arrange a filter with large filter area such that the flow of air must pass through the filter.
  • the cleaner body has a lower side intended to be arranged towards a floor surface, an upper side in which the cavity is defined and a forward and an aft end.
  • an elongated brush roll with a first and a second end is arranged in a recess in the lower side of the cleaner body, said brush roll is extending substantially transverse to a longitudinal direction of the cleaner.
  • One embodiment of the autonomous cleaner furthermore comprises a brush roll engine adapted rotate the brush roll, the engine is arranged close to the longitudinal axis behind the brush roll and an elongated drive shaft extending from the engine towards one end of the brush roll where a drive transmission is arranged.
  • the defined position and design of the brush roll engine and the drive shaft makes it possible to arrange the engine in a position within the cleaner body that makes it possible to increase the volume of the dust container since the engine is arranged in front of the dust container close to the bottom structure of the cleaner body.
  • One embodiment of the autonomous cleaner comprises two drive units each comprising a wheel and an engine powering the wheel, said drive units are arranged behind the brush roll adjacent to the first and second end of the brush roll and said brush engine is arranged between the first and second drive unit.
  • the use of two separately arranged drive units facilitates the installation since each wheel has its dedicated small electrical engine arranged in direct relation to respective wheel.
  • the engines of the drive units are electrical engines powered by at least two battery packs arranged separately within the cleaner body. Electrical engines are small, reliable and efficient. Furthermore, the use of two battery packs reduces the overall size of each battery pack which makes it easier to fit the battery packs within the cleaner body and ensures a reliable powering of the cleaner since each battery pack will be able to power the cleaner individually for a period of time.
  • the drive units furthermore comprise a wheel suspension extending in forward direction from the wheel shaft.
  • the wheel suspension makes it easier for the cleaner to access areas where the floor structure is rough and obstacles are arranged on the floor surface.
  • the cleaner body has a substantially triangular shape with a wider forward than aft end.
  • the brush roll is arranged in the forward end and the dust container in the centre of the cleaner body.
  • the triangular shape improves the possibilities for the cleaner to access areas that otherwise would have been difficult to reach.
  • An autonomous cleaner 10 is illustrated in perspective in figure 1 .
  • the cleaner has a cleaner body 11 in which all cleaner components are arranged.
  • the cleaner body is enclosed by a cleaner casing 12 that surrounds the different components arranged within the cleaner body.

  • the brush roll is provided with at least one brush 20 and / or elastic rib 21 that extend along the roll 22 either substantially straight along the brush roll, or helically around the brush roll.
  • the brush roll in the forward end of the cleaner body is intended to lift and collect particles from the floor surface and transports them via a dust passage 24 to a dust container 25 arranged in the centre of the cleaner body 11.
  • Behind the brush roll 19 an engine 81 for rotating the brush roll is arranged.
  • the engine is arranged close to the longitudinal axis L with the drive shaft 82 extending substantially parallel to the brush roll 19.
  • the drive shaft 82 is extending all the way to one of the brush roll ends where the drive shaft via a drive transmission rotates the brush roll 19.
  • the engine is arranged close to the bottom structure 83 of the cleaner free space within the cleaner body behind and above the engine.
  • the engine is preferably an electrical engine powered by two battery packs 84 arranged close to the inner surface of the cleaner casing 12 in the aft of the clearer body. Two small battery packs are more easily fitted within the cleaner body than one larger battery and the position of the battery packs in the aft increases the space in the centre of the cleaner body for the dust container 25.
