Definitions

  • the invention relates to a cleaning device for a floor cleaning machine, wherein the cleaning device comprises a brush housing having a housing middle part and two identically designed housing side parts, wherein the brush housing defines a brush space in which two brush rollers are arranged, and wherein each brush roller with a front side on a housing side part driven by a motor is rotatably mounted and is rotatably mounted with the other end face on an abutment part of the cleaning device.
  • the invention relates to a floor cleaning machine, comprising at least one cleaning device.
  • Cleaning devices of the type mentioned are used for cleaning a floor surface for use. They are arranged on a floor cleaning machine, and for cleaning the bottom surface, the brush rollers are rotated by a motor.
  • the brush rollers are each rotatably supported on a housing side part of a brush housing and on an abutment part.
  • the counter-bearing parts are frequently formed by lateral wiping members held on the middle part of the housing for wiping off the floor surface to be cleaned. This has proved to be unfavorable for the storage of the brush rollers, because unevenness of the floor surface to be cleaned can be detected by the lateral Abstreifgliedern. This can lead to unwanted wobble of the brush rollers.
  • Object of the present invention is to provide a generic cleaning device and a generic floor cleaning machine, the brush rollers are stored more stable.
  • the cleaning device comprises two brush rollers.
  • the first brush roller is mounted with its first end face on the first housing side part and with its second end face on the first abutment part.
  • the second brush roller is mounted with its first end side on the second housing side part and with its second end side on the second abutment part.
  • the first abutment part is held on the second housing side part and the second abutment part on the first housing side part.
  • the first brush roller is also indirectly supported on the second housing side part
  • the second brush roller is also indirectly supported on the first housing side part.
  • the abutment parts can be optimized specifically with regard to the stability of the storage of the brush rollers. As a result, a more stable storage of the brush rollers can be achieved overall.
  • the identical design of the housing side parts makes it possible to keep the manufacturing costs for the cleaning device low. For a further reduction of the manufacturing cost of the cleaning device, it is advantageous if the counter-bearing parts are also formed identically.
  • the abutment parts are designed as die-cast parts.
  • they are made of a metal, for example aluminum or an aluminum alloy.
  • the housing side parts are formed as die-cast parts, because this makes it possible to further increase the stability of the bearing of the brush rollers.
  • the housing side parts are made of a metal, for example aluminum or an aluminum alloy.
  • the middle part of the housing at least partially forms a hollow body with a top wall and a bottom wall. This makes it possible to give the middle part of a high stiffness, while it can be formed simultaneously low in weight. In this way, a high rigidity can then also be imparted to the brush housing and thus to the cleaning device.
  • the hollow body formed by the middle part of the housing may, for example, be arranged above the brush space, the bottom wall of the hollow body being a wall bordering the brush space on the top.
  • the ceiling wall of the Hoh stresses may be formed for example by a ceiling wall of the middle part. For further stiffening of the housing middle part of the hollow body may be divided by partitions into individual sections.

  • the wiper members may be movably mounted on the brush housing and, for example, from an operating position in which they bear against the brush housing, in a maintenance position and vice versa be transferred, in which the user access to the abutment parts is made possible.
  • the cleaning device comprises at least one second locking device for securing the arrangement of each wiper member on the brush housing. As a result, it can be ensured that the wiper members do not detach undesirably from the brush housing.
  • the at least one second locking device conveniently comprises a first locking member which is arranged on the brush housing, in particular on a housing side part, and which cooperates with a second locking member arranged on a stripping member.

This allows the first wiper member 136 from an operating position in which it rests against the brush housing 30 ( FIGS. 2 and 3 ) and locked by means of the second locking means 146, to transfer to a maintenance position, which allows the user access to the abutment member 56. This allows the user, for example, to exchange the brush rollers 16 and 18 as described above.
  • the first stripping member 136 can be pivoted from the service position to the operative position, whereupon the second latch 146 can be transferred from the release position to the lock position by rotating the first latch member 148 about the pivot 132 about the first stripping member 136 to lock.
  • the cleaning device 14 Due to the possibility of being able to arrange in the locking member receptacles 118, 128 and 130 each identically formed locking members in order to lock the abutment members 56 and the first wiper member 136 and the second wiper 138, the cleaning device 14 according to the invention has a very high versatility and is inexpensive to produce. The use of identically formed locking members also simplifies the handling of the cleaning device 14.
  • housing side parts 34 are placed on their outer side facing away from the brush space 54 cover members, of which in the FIGS. 2 and 3 only one cover member 154 is shown.
  • cover members 154 By the cover members 154, the housing side parts 34 and in particular the drive means 62 can be protected from dirt and cleaning liquid.
  • the cover members 154 have on their side facing the respective housing side part 34 a plurality of not visible in the drawing cam-like projections. These can engage with a plurality of recesses 156, which are formed on the edge 112 of the first locking member 98 of the first locking means 96 and the first locking member 148 of the second locking means 146.
  • the locking member 98 and the locking member 148 thereby lock both in its locking position and in its release position with the cover member 154 and therefore assume with respect to this secured and defined positions. This secures the support of the abutment member 56 on the housing side part 34 and the wiper members 136 and 138 on the housing side part 34 in addition, because inadvertent rotation of the locking member 98 and the locking member 148 can be avoided.
