  • the hard surface cleaning device has a suction nozzle on which at least one Abziehlfl is arranged, and can be moved in the manner of a manual Breabziehers along the hard surface, so that accumulates liquid in the region of the suction opening.
  • the suction opening is in fluid communication with a suction unit, with the aid of which the suction opening can be acted upon by a suction flow, so that a mixture of liquid and air can be sucked from the suction opening.
  • a deposition chamber is positioned between the suction nozzle and the suction unit.
  • a separation device for separating liquid from the liquid-air mixture is arranged in the deposition chamber.
  • the separated liquid passes from the deposition chamber into a dirty liquid tank which is releasably held in a tank receiving compartment of the hard surface cleaning apparatus is.
  • the suction unit has a suction turbine, which is surrounded by a turbine housing.
  • the turbine housing is connected via a Turbineneinlassteil with the deposition chamber, so that the suction turbine can suck air from the deposition chamber.
  • Such Hartviditessetti are from the EP 2 237 711 B1 and the EP 2 230 980 B1 as well as from the EP 2 227 126 B1 known. They have proven themselves in practice. With their help windows in particular can be cleaned within a short time. The user can guide the portable hard surface cleaning device with the at least one Abziehlippe on the window pane and remove liquid located on the window pane.
  • the operation of the known Hartviditesstechnik is associated with a certain operating noise. It is desirable to reduce the noise of such hard surface cleaning equipment.
  • Object of the present invention is therefore to develop a hard surface cleaning device of the type mentioned in such a way that it has a lower noise.
  • a hard surface cleaning device of the generic type according to the invention that the turbine housing is connected via a turbine outlet with the tank receiving compartment, wherein a wall of the tank receiving compartment and the dirty liquid tank limit an air outlet, in which opens the turbine outlet and via which sucked by the suction turbine Air can be discharged to the environment.
  • the idea flows in that the noise of the hard surface cleaning device can be reduced in that the exhaust air of the suction turbine is not directly delivered to the environment of the hard surface cleaning device but first an air outlet space is supplied, which is between a wall of the tank receiving compartment and the in the tank receiving compartment used dirty fluid tank is located. outgoing From the suction turbine thus the exhaust air is first supplied to the air outlet space, and from the air outlet then the exhaust air can be discharged to the environment.
  • the portable hard surface cleaning device according to the invention is characterized by a relatively low noise.
  • the portable hard surface cleaning device according to the invention has the advantage that it can be produced more cheaply, because unlike known Hartviditess expertn molded into a housing of Hartviditess réelles vents omitted, rather, the exhaust air of the suction turbine can be delivered to an air outlet space extending between a wall the tank receiving compartment and the dirty liquid tank extends.
  • the portable hard surface cleaning device has a base housing, in which the turbine housing is arranged.
  • the basic housing forms the tank receiving compartment.
  • the basic housing can advantageously be formed by two housing halves.
  • the portable hard surface cleaning device has a separation unit, in which the deposition chamber is arranged.
  • the separation unit is releasably connected to the suction nozzle.
  • the separation unit is releasably connected to a housing of the hard surface cleaning device receiving the turbine housing.
  • the dirty liquid tank inserted into the tank receiving compartment forms a deflecting element with the aid of which the exhaust air flowing into the air outlet space from the suction turbine via the turbine outlet part is deflected.
  • the dirty liquid tank thus forces a deflection of the exhaust air, and this in turn leads to a further noise reduction.
  • the air outlet space forms a flow labyrinth, which is bounded on the one hand by the wall of the tank receiving compartment and on the other hand by the dirty fluid tank.
  • the provision of a flow labyrinth makes it possible to keep the noise of the portable hard surface cleaning device particularly low.
  • the flow labyrinth may, for example, extend along a rear region of the contaminant tank as well as along longitudinal sides of the contaminant tank remote from one another. The exhaust air of the suction turbine thus undergoes several changes of direction on its way from the turbine outlet part to the surroundings of the hard surface cleaning device.
  • the dirty liquid tank is made of an elastically deformable plastic material, because thereby the dirty liquid tank inserted into the tank receiving compartment forms an acoustic insulating element under the effect of which the noise development can be kept particularly low.
  • the exhaust air from the suction turbine impinges within the tank receiving compartment on the dirty liquid tank, which can deform slightly under the action of the exhaust air and thereby the flow of exhaust air takes energy and thus reduces the noise.
  • the turbine inlet part is configured as a turbine inlet line, which extends from the turbine housing to the deposition chamber. This makes it possible to optimize the flow path of the air and thereby reduce the noise.
  • the turbine inlet line is advantageously formed in one piece, wherein it opens directly into the deposition chamber and is connected with its end facing away from the deposition chamber directly to the turbine housing of the suction turbine.
  • the turbine inlet conduit may be in the form of a length of tubing extending from the deposition chamber to the turbine housing.

  • the upper housing part can be latched to the lower housing part.
  • the housing upper part continuously tapers in the direction of the turbine inlet line. This allows flow losses to keep the air sucked from the deposition chamber via the turbine inlet line to the suction turbine low.
  • the upper housing part of the turbine housing is bell-shaped and covers the suction turbine, wherein the turbine inlet line integrally connects to the upper housing part.
  • Particularly low flow losses can be achieved in an advantageous embodiment of the invention in that the turbine inlet line is designed arcuate.
  • This allows a fluidically optimized design, so that a high efficiency can be generated.
  • the high efficiency has the advantage that even with the use of a suction unit with relatively low power an effective suction flow can be achieved, so that a mixture of liquid and air can be reliably sucked from the suction port.
  • the lower power of the suction unit in turn makes it possible to use a relatively small drive motor. As a result, not only the noise development of the hard surface cleaning device according to the invention can be kept low but also its energy consumption.
  • the portable hard surface cleaning device comprises rechargeable batteries. This makes it possible to use the portable surface cleaning device even when no power supply is available.
