  • the cleaning machine can be operated, so to speak, always with optimum performance, ie to be flowed through with a maximum water flow.
  • the machine can remain permanently under water until the dirt collector is full. During this time, the cleaning effect or filter effect is optimal.
  • the suction power is not degraded by a peu à peu zuszus with dirt adding filter unlike the prior art just. A possibly even only partially forming filter cake is removed by the cleaning device continuously, whereby the cleaning performance of the cleaning machine is optimal and remains.
  • the cleaning device comprises non-flow-bonded mechanical cleaning means for cleaning the at least one filter or is formed thereby.
  • the at least one filter is mechanical in nature, i. For example, at least not exclusively by a countercurrent principle, is cleaned.
  • the mechanical cleaning means include, for example, one or more wipers to which or relatively the filter is moved or which is relatively move to the filter, vibration means or vibrator to vibrate the at least one filter or the like.
  • the mechanical cleaning is still supported by a countercurrent principle or at least in combination, the mechanical cleaning and a countercurrent principle are provided.
  • only or exclusively mechanical cleaning agents can be provided.
  • the cleaning device expediently has at least one wiper for removing dirt from the at least one filter.
  • the scraper makes a relative movement along the surface of the at least one filter, i. that, for example, the scraper is guided past the filter or the filter is guided past the scraper. It is also a so-called double movement possible, i. that both the scraper and the at least one filter to be cleaned are moved.
  • a relatively quick cleaning i. that the scraper cleans a respective area of the at least one filter with a cycle time of about 0.5 to 2 or even 3 contact times per second is advantageous.
  • a rotational speed of, for example, 0.5-3 revolutions per second is advantageous.
  • the filter remains very clean.
  • a type of filter belt is also conceivable, ie that a filter can be guided past a respective scraper, for example by a circulation movement, in particular also a linear circulation movement.
  • the filter belt can, for example, circulate like a conveyor belt, wherein the at least one wiper strikes the filter belt, for example a textile belt.

  • Preference is also a tightness between the lid on the one hand and the housing on the other.
  • This tightness can be advantageously provided by eccentric contours between the lid and the housing. When the cover is rotated relative to the housing, the eccentric contours come into sealing, contacting contact with each other and thus form a seal.

  • the brush is preferably very soft, so that it does not damage a possibly sensitive surface of the at least one filter.
  • the at least one scraper can definitely comprise several components which come into engagement with the respective filter in parallel or successively. So it is conceivable, for example, that a rough cleaning with, for example, a kind of stripper lip takes place, while then a brush still does the fine cleaning work.
  • the at least one scraper may have a particularly long effective contact line for contact with the at least one filter, for example by a curvature, by a zigzag course or the like.

  • the arrangement is made such that a radially outer sealing surface 72 on the outer circumference of a Flanschvorsprungs 73 of the dirt collecting container 46 and a radially inner sealing surface 74 on the inner circumference of the retaining ring 70 have a certain eccentricity of the type, the sealing surfaces 72, 74 during rotation from the release position ( FIG. 4 ) in the closed position ( FIG. 5 ) come into sealing contact with each other.
  • the retaining ring 70 has a stepped shape such that the bearing receptacle 68 remains free for the rotational movement of the filter holder 64.
  • the retaining ring 70 carries a support structure, such as a grid 76, which supports the filter fabric 65 on the upper side or downstream, against the force of the water flow W.
  • a flow-impermeable supporting part 77 is provided above the cleaning device 60.
  • the support part 77 may, for example, have the advantage that at this point a possible flow-calm zone is formed and / or the cleaning process is not disturbed as possible.
  • An advantage of the support section 77 is also to be seen in the fact that the filter fabric 65 is supported against the action of the scraper 61, so this can strip dirt from the filter fabric 65 in an optimal manner.
  • FIG. 10 Other cleaning principles are related to FIG. 10 indicated.
  • a cleaning device 160 which would preferably be arranged in the region of the opening 58, a countercurrent device 161, for example, a turbine for generating a direction of the dirty water flow S opposite counterflow G have.
  • a vibration generating device 261 e.g. a vibrator or an ultrasonic unit is provided, which constitutes a further cleaning device 260.
  • the vibration generating device 261 may generate ultrasonic vibrations that cause the filter 50 to vibrate and in any case ensure that particles or other dirt from the filter 50 are cleaned.
  • the scraper 61 and the vibration generating device 261 form mechanical cleaning agents 90, 290 or components thereof.
  • a cleaning device does not necessarily have to be in the dirt collecting space of the cleaning machine, but can also be placed outside, for example.
  • the cleaning devices 160, 260 are arranged on the outside of the cover 18.
