Definitions

  • the present invention relates to a floor cleaning machine, with a machine housing that extends along a longitudinal axis of the floor cleaning machine between a front end and a rear end, with a cleaning liquid container accommodated in the machine housing, with a dirty liquid container accommodated in the machine housing, with a chassis with wheels, which carries the machine housing and is designed such that the floor cleaning machine can be moved over a floor surface to be cleaned, the chassis having at least one front wheel and at least one rear wheel, which are spaced apart from one another along the longitudinal axis, the chassis is designed to be steerable, so that a direction of travel along which the floor cleaning machine moves over the floor surface to be cleaned can be changed, with a cleaning device with cleaning elements which are designed to intervene with the floor surface to be cleaned when the floor cleaning machine is moved over the floor surface to be cleaned , with a device for applying cleaning liquid from the cleaning liquid container to the floor surface to be cleaned, which is designed such that the cleaning liquid is applied in such a way that the cleaning liquid reaches the area of the cleaning device, and
  • Such floor cleaning machines are known from the prior art.
  • cleaning liquid such as fresh water from the cleaning liquid container is applied to the floor surface to be cleaned using the device provided for this purpose, the cleaning elements engaging with the floor surface in order to remove dirt from it in cooperation with the cleaning liquid.
  • the dirty liquid receiving device which can be designed, for example, as a suction cup, the previously applied cleaning liquid, which is contaminated with dirt after the cleaning elements engage with the floor surface, so that it is dirty liquid, is picked up again and placed in the dirty liquid container.
  • Such so-called scrubber dryers can be designed as hand-held or ride-on machines. It is also possible for such machines to be designed as autonomously driving so-called cleaning robots, so that no operator directly monitors the operation.
  • the dirty liquid receiving device i.e. usually the suction cup, extends at least over the entire width of the floor cleaning machine and often also protrudes laterally to ensure that dirty liquid that has been applied to the floor surface to be cleaned is completely picked up again and placed in the dirty liquid container becomes.
  • a lateral projection beyond the width of the cleaning device is particularly necessary so that the dirty liquid receiving device covers the entire area in which dirty liquid has been distributed by the cleaning device, even when cornering.
  • the dirty liquid receiving device is mounted behind the rear wheels when viewed in the direction of travel, which means that when the machine corners in one direction, the dirty liquid receiving device swings outwards on the side of the machine facing away from the inside of the curve. This can cause a problem if the machine moves along an object such as a shelf or wall and then needs to be moved laterally away from it.
  • the term "object” in the sense of the present application is to be understood as meaning any type of element extending away from a floor surface to be cleaned. Accordingly, this should include furnishings such as furniture and other items that may only be temporarily arranged on the floor surface to be cleaned. Furthermore, in the context of the present application, this term should also include vertically extending walls.
  • the present invention is therefore based on the object of providing a floor cleaning machine whose dirty liquid collection device is mounted in such a way that it can move laterally close to objects and yet curves away from the object are possible without there being contact between the Dirty liquid collection device and the items in question come.

  • the dirty liquid collection device is therefore attached in the area of the rear end and also behind the rear wheels when viewed in the direction of travel of the machine.
  • the dirty liquid receiving device is designed to collect dirty liquid on the floor surface to be cleaned. In a preferred embodiment, this can be done in that the dirty liquid receiving device has a suction volume which is open over the entire width of the dirty liquid receiving device relative to the floor surface to be cleaned and is also connected to the dirty liquid container.
  • a suction device is used to generate a lower pressure than the environment, i.e. a negative pressure, so that an air flow is generated from the suction volume into the dirty liquid container, which entrains the dirty liquid and thus conveys it into the dirty liquid container.
  • the dirty liquid receiving device is slidably mounted on the machine housing between a retracted position and an extended position, the dirty liquid receiving device being in the retracted position along the longitudinal axis, which is defined by the machine housing and between the front and the rear end extends, which is closer to the at least one rear wheel than in the extended position.
  • the dirty liquid receiving device can therefore be moved, preferably parallel to the longitudinal axis. If the floor cleaning machine according to the invention is moved at a short lateral distance along an object such as a shelf or a wall and is to make a curve away from this object, the dirty liquid receiving device is moved from the extended to the retracted position, which means that it only swings out towards the object to a lesser extent when the floor cleaning machine curves away from the object.
  • the dirty liquid receiving device remains in the extended position to ensure that when the floor cleaning machine executes the curve, the entire area is also on the outside of the curve is detected by the dirty liquid receiving device, which had previously been swept over by the cleaning device and thus contains dirty liquid.
  • the ability to move the dirty liquid receiving device between two positions viewed along the longitudinal axis makes it possible for the floor cleaning machine to be moved along an object at a small lateral distance and, based on this, to be able to corner without the floor cleaning machine or its dirty liquid receiving device coming into contact with the object comes.

  • a sensor arrangement is provided which is designed to detect a distance perpendicular to the longitudinal axis between the machine housing and an object which, viewed along the longitudinal axis, is arranged to the side of the floor cleaning machine. This makes it possible to automatically detect whether a minimum lateral distance to an object has been exceeded, where the dirty liquid receiving device comes into contact with this object when cornering. In a further preferred embodiment, this can be done by a user are displayed. However, it is also possible for a corresponding signal to be processed accordingly by a control unit of the floor cleaning machine.
  • a control unit which is in signal connection with the sensor arrangement and which is connected to the drive, the control unit being configured to control the drive so that the dirty liquid receiving device is moved into the retracted position when a Distance detected by the sensor arrangement falls below a predetermined threshold value.

  • the control unit is configured to determine a route and control the floor cleaning machine so that it follows the route.
  • the problem of contact of the dirty liquid receiving device with objects arranged laterally to the floor cleaning machine is, as already explained, particularly problematic because no user can immediately assess whether such contact will cause damage. It is therefore particularly advantageous in such robots if the movement of the dirty liquid receiving device between the extended and retracted positions is automated, as already described, using a drive and a sensor arrangement.
  • the dirty liquid receiving device is mounted on the machine housing so as to be pivotable about a vertical axis, which extends relative to the machine housing in such a way that, during operation, it extends perpendicular to the floor surface to be cleaned. This makes it possible for the dirty liquid receiving device to come into contact with an object to move sideways.
  • the dirty liquid receiving device can be moved between a lowered and a raised position, the dirty liquid receiving device being closer to a floor surface to be cleaned in the lowered position than in the raised position and the dirty liquid receiving device preferably resting against the floor surface to be cleaned in the lowered position .
  • the cleaning device has a first width measured perpendicular to the longitudinal axis and the dirty liquid receiving device has a second width measured perpendicular to the longitudinal axis, the second width being greater than or equal to the first width.
  • the dirty liquid receiving device is designed as a so-called suction base and has a base body from which a front and a rear suction lip extend, which extend transversely to the longitudinal axis and are spaced apart from one another in the direction of the longitudinal axis, so that between the suction lips and a suction volume is formed on the base body, wherein the suction lips are designed to come into contact with a lower edge with the floor surface to be cleaned and a connecting line is provided which extends between the base body and the dirty liquid container, so that the suction volume and the dirty liquid container are in fluid connection stand with each other.
  • a suction device is connected to the dirty liquid container so that it can be pressurized, through which in turn an air flow can be generated from the suction volume through the connecting line into the dirty liquid container, which entrains dirty liquid from the suction volume into the dirty liquid container .
  • an operating unit is mounted on the machine housing and has operating elements that can be operated by a user, the operating unit being movable between a retracted position and an extended position when viewed along the longitudinal axis, the operating unit viewed along the Longitudinal axis is closer to the front end in the retracted position than in the extended position.

  • the dirty liquid container 5 is in turn connected to a suction device 51, so that a lower pressure in relation to the ambient pressure can be generated inside the dirty liquid container 5, so that in turn an air flow can be generated from the suction volume 49 into the dirty liquid container 5, through which then on the Dirty liquid located on the floor surface 15 to be cleaned is entrained and conveyed into the dirty liquid container 5.
  • the dirty liquid receiving device 41 is held via its base body 43 on a guide rod 53, which in turn is attached to a holder 57 so that it can pivot about a pivot axis 55.
  • the holder 57 in turn can be moved by motor essentially parallel to the floor surface 15 to be cleaned and also parallel to the longitudinal axis 21 relative to the machine housing 3 using a linear drive 59 along a guide rail 61, the linear drive 59 being connected to the control unit 39 in a manner not shown .
  • the linear drive 59 With the help of the linear drive 59, the Dirty liquid receiving device 41 parallel to the longitudinal axis 21 between a retracted position ( Figures 4 and 5 ) and an extended position ( Figure 3 ).
  • the dirty liquid receiving device 41 in the form of the suction cup can be inserted into the in Figure 3 shown extended position, in which the dirty liquid receiving device 41 is further beyond the rear end 25 of the machine housing 3, ie the dirty liquid receiving device 41 is, viewed along the longitudinal axis 21, further away from the rear wheel 11 than in the Figures 4 and 5 shown retracted position, which is achieved by retracting the linear drive 59 so that the holder 57, which holds the guide rod 53, is moved along the guide rail 61 towards the rear wheel 11.
  • the dirty liquid receiving device 41 in the form of the suction base can be pivoted about a vertical axis 69, which during operation, i.e. when the dirty liquid receiving device 41 is in the lowered position, runs essentially perpendicular to the floor surface 15 to be cleaned.
  • a position, pivoted from a straight position of the suction cup is in Figure 7 to recognize what emerges from the fact that the free ends 71 of the dirty liquid receiving device 41 have different positions along the longitudinal axis 21.
  • the width that the dirty liquid receiving device 41 has is obviously larger than the width that the cleaning device 27 has, these widths being determined perpendicular to the longitudinal axis 21.
