Definitions

  • the invention relates to a suction device attachment for wet cleaning of surfaces, especially vertical ones Surfaces, with a liquid application device.
  • Cleaning devices for the wet cleaning of surfaces, in particular of vertical window surfaces are in one Variety of variations known. They exist for the time being from a suction device, which next to a suction device also via a reservoir for the cleaning liquid disposes.
  • the cleaning liquid is pressurized from the suction device via a pressure line fed to the actual cleaning device attachment and there over nozzles, brushes, sponges or the like applied to the surface to be cleaned.
  • the applied Liquid is then removed from the suction device often slot-shaped suction mouth and the adjoining one Suction channel sucked up again.
  • Such Cleaning devices are mostly designed as industrial devices and accordingly voluminous and expensive and for not suitable for normal household use.
  • a cleaning device is known from EP 0 243 323, in which a liquid application device with a cleaning liquid or a cleaning steam there is supplied via a pressure line.
  • a liquid application device with a cleaning liquid or a cleaning steam there is supplied via a pressure line.
  • the area is the liquid application device there provided with a sponge that is inside a suction cup housing around a surface to be cleaned parallel axis pivotally arranged in a working position is. Parallel to the length of the sponge or its axis and thus transverse to the usual working direction is also a slit-shaped suction mouth above the surface to be cleaned, with a sealing lip just sitting on it.
  • Suction cup housing and suction mouth are with a suction channel in connection within which also the pressure line arranged for the supply of the cleaning liquid is.
  • Cleaning device attachment and the cleaning device form a functional unit and cannot be used in isolation from each other.
  • a Suction device attachment for wet cleaning of surfaces described which as preferred also in the sense of this Invention as a front attachment of pure suction devices, e.g. household suction devices are also used. It is there as here important that a pressure line from the suction device to the liquid application device can be omitted and the suction device alone on the possibility a suction, so no tank system and pressure system especially for the cleaning liquid contains.

  • the suction power is particularly good in household suction devices also limited.
  • Long suction channels e.g. in shape of hoses and, if necessary, filter devices further flow resistances represent the suction power reduce even further.
  • It can extract power a suction device attachment with respect to one surface to be cleaned applied cleaning liquid through the independent combination of features of Claim 2, in particular also in connection with the Features of claim 1, are improved if is based on the fact that the suction mouth is transverse to their longitudinal extent divided into individual suction sections which is in the suction direction in a common Suction chamber open, where preferably several Intake manifold branches are connected, which continue in Suction direction to a common cross section of the suction channel are summarized. This measure will a uniform speed profile of the entry speed reached in the suction mouth.
  • suction pipe branches are behind the suction direction to a common suction channel cross section a suction channel summarized, which ultimately in the suction device ends. Improving suction performance also serves the measure that the suction mouth delimiting inner wall immediately and continuously a sealing lip merges. Usually these are Sealing lips that prevent the application of the applied cleaning liquid serve in a U-shaped groove of the Suction channel housing bordered. This creates in the Wall a jump at which it may be too a jam of the withdrawn water during suction can.
  • the suction speed is increased even more that the outer cross-sectional area of the suction mouth on a suction nozzle with a width of less than 5 mm, preferably less than 2 mm, is reduced opposite a subsequent suction section, wherein in Suction direction the length of the suction nozzle about its width corresponds.
  • this measure includes a drop the suction mouth after switching off the suction device attachment or suction device largely, because at one Precipitation of the aspirated liquid in the area
  • the common suction chamber itself Liquid in the area of this cross-sectional change will collect. Leakage of fluid through the Suction nozzle of such a small width already appears by the surface tension of a drop of water as almost impossible.
  • it also only very small solids with sucked up, so that it is authorized by an absorbed liquid-air mixture just to speak.
  • a change in position is the Liquid application device provided, for example an inactive location with only one peel and / or Suction function of the suction device attachment without liquid application in a position of use with suction the applied cleaning liquid and another Position in which only cleaning liquid is applied and suction and / or peeling not happened.
  • a guide is arranged inside the bow, in which the liquid application device slider controlled linear is movable. Despite the arched overlap the liquid application device by in particular a specially designed suction channel housing becomes one linear displaceability is preferred because of this It's easy to train leadership.
  • central training is preferred only a single slide, which then the suction channel housing interspersed approximately in the middle, then the Schieher and if necessary the guidance between intake manifold branches are arranged. This does not make the suction channel itself enforced and sealing problems or the like are eliminated.
  • the security concept continues The measure takes into account behind any Phase separator a safety valve in the suction direction still to be provided, namely one in the suction direction splash water valve located behind the phase separator, if there is insufficient phase separation closes the cross section of the suction channel.

  • Modern household vacuum cleaners come with overload protection devices provided today so that the closing of the Suction channel causes no problems, but rather the suction device even when larger amounts of liquid appear, which is the capacity of the phase separator overwhelmed, reliable before entering is protected from liquids.
  • In development provided that in the phase separator separated liquid in a tank outside the Suction channel is collected. This will narrow the cross-section of the suction channel avoided flow losses in the suction channel are also kept low.

As a result of the latter measure then also with the tank inflow by a wrong one Handling the vacuum attachment no liquid emerge and if necessary into the further suction channel reach. In particular, it can then also be provided be that the tank in the suction direction behind the tank inflow the separated liquid with the suction channel is connected via an intake duct.

This is done in the swirl channel section of essentially rotationally symmetrical and in particular round cross section preferably tangential introduced the flow of the liquid-air mixture. Due to the vacuum on the suction device side gets inside of the swirl channel section this flow too another component in the suction direction, but retains nevertheless the rotary component of the movement of the Liquid-air mixture.
