Definitions
- the invention relates to a Hart vomabsaug réelle with a suction nozzle and a suction unit, which is in flow communication with the suction nozzle via a flow path for sucking a liquid-air mixture from a hard surface, and with a separator for separating liquid from the liquid-air mixture and with a Dirty liquid tank for receiving the separated liquid.
- Such Hart vomunabsaugered can be used for the suction of hard surfaces, especially tiled walls or floors or for removing a water film of windows or glass doors.
- a suction flow can be achieved by means of the suction unit, so that dirt particles and water droplets can be sucked through the suction nozzle from the hard surface and transferred into the dirty liquid container.
- Such Hart vomabsaugered are known for example from US Pat. Nos. 3,254,360 and 3,118,165.
- Hartvidabsauguze be described in DE 2555648 Al.
- US Pat. No. 6,347,428 also discloses such a hard surface suction device, wherein the hard surface can not only be sucked off, but alternatively the hard surface can be cleaned by means of a rotatable brush.
- the suction flow generated by the suction unit can be passed either through a suction port of the suction nozzle or through a rotor through which drives the brush via a gear.
- the suction stream emanating from the suction mouth of the suction nozzle is led through the dirty liquid tank for sucking off the hard surface, liquid droplets within the dirty liquid tank being removed from the liquid-air mixture. to be divorced.
- This has the disadvantage that the Abscheid Koch depends on the level within the dirty liquid tank.
- US Pat. No. 6,691,369 describes a hard surface suction device in which the dirty fluid tank is separated from the flow path between the suction nozzle and the suction unit by means of a float. The separation effect is thus not affected by the level of the dirty liquid tank. However, there is a risk that liquid located in the dirty liquid tank again comes out of the suction nozzle, if the Hart vomabsaug réelle is oriented obliquely to the vertical. In particular, when transporting the Hart vomabsaug advocatess after a successful operation, therefore, the user has to make sure that he keeps the Hartvidabsaug réelle in a predetermined position.
- Object of the present invention is to develop a Hart vomabsaug réelle of the type mentioned in such a way that it forms regardless of the level of Schmutz problemkeitstanks a constant suction flow, without the risk that fluid in the dirty liquid tank can emerge from this again.
- a deposition chamber is arranged, which receives the separator and which is connected to the dirty liquid tank, wherein the flow path from the suction nozzle to the suction unit passes the dirty liquid tank and wherein the hard surface suction device has a filling device with a filling channel, which has an inlet Filling opening, wherein the dirty liquid tank forms a collecting space for separated liquid, which is arranged relative to an upright position of Hartdonabsauguzes below the filling opening, and a surrounding the filling channel Ausweichraum which receives liquid from the upright position when pivoting the Hartvidabsaug réelles from the upright position ,
- the separation of liquid from the aspirated liquid-air mixture takes place in a separation chamber, which is arranged in the flow path between the suction nozzle and the suction unit and which is connected to the dirty liquid tank.
- the separated liquid collects without affecting the suction flow caused by the suction unit.
- the suction flow does not reach through the dirty liquid tank and is thus independent of the filling level of the dirty liquid tank.
- the separation effect does not depend on the level of the dirty liquid tank, since the separation takes place outside of the dirty liquid tank.
- a filling device is provided with a filling channel having a filling opening having. Liquid that has been separated from the liquid / air mixture in the separation chamber can enter the dirty liquid tank via the filling opening.
- the dirty liquid tank forms a collecting space for the separated liquid below the filling opening out.
- the dirty liquid tank in the area surrounding the filling channel comprises an escape space, which receives liquid from the collecting space during pivoting of the hard surface suction device from the upright position.
- the filling channel preferably projects into the dirty liquid tank and the filling opening is arranged inside the dirty liquid tank.
- the area surrounding the filling channel within the dirty liquid tank thus forms the escape space, which can absorb the liquid in the collecting space when the hard surface suction device is pivoted out of the vertical.
- the filling channel is arranged outside the dirty liquid tank, wherein the dirty liquid tank at least partially surrounds the filling channel in the circumferential direction in order to form the escape space.
- the volume of the escape space is at least as great as the volume of the collecting space, because this allows the collecting space to be completely filled with liquid, and during the pivoting of the hard space. surface suction device from its upright position, the entire, located in the collecting space liquid can be absorbed by the escape space.
- the filling opening is arranged approximately halfway up the dirty liquid tank in relation to an upright position of the hard surface suction device.
- the collected in an upright position of the Hartvidabsaugowskis the separated liquid collecting space may extend from a bottom wall of the dirty liquid tank up to the lower edge of the halfway arranged filling opening, and the swirling of Hartvidauguzes from the vertical position liquid from the collecting space receiving alternative space can be based on an upper edge of the filling opening extend to a ceiling wall or, for example, up to a filler neck or generally to the upper boundary of the interior of the dirty liquid tank.

- the filling device has a ventilation channel which dips into the dirty liquid tank and projects beyond the filling channel on the side facing away from the filling opening and has a ventilation opening inside the dirty liquid tank.
- the dirty liquid tank can be ventilated via the ventilation channel. Since the ventilation channel protrudes beyond the filling channel in the direction of the deposition chamber, ie on the side facing away from the filling opening of the filling channel, liquid can flow from the separation chamber to the end region of the ventilation channel facing the separation chamber in order to reach the dirty liquid tank via the filling channel. At the same time, air can escape unhindered from the dirty liquid tank via the ventilation duct.
- the ventilation opening of the ventilation duct arranged inside the dirty fluid tank is arranged at the same height with respect to the vertical as the filling opening of the filler channel. This has the advantage that below the ventilation opening of the above-described collecting space for separated liquid is located and above the ventilation opening of the discharge channel surrounding the escape space for liquid is arranged. There is therefore no risk that liquid can flow out of the dirty liquid tank via the ventilation channel.

- the ventilation channel passes through the filling trough.
- the filling trough can be inserted into an inlet connection of the housing of the dirty liquid tank.
- a sealing element in particular a sealing ring, can be arranged between the filling trough and the inlet nozzle.
- the filling trough is surrounded by a support ring, which can be placed on an inlet connection of the housing of the dirty liquid tank.
- the support ring thus forms a stop, which can be applied to an end face of the inlet nozzle.
- a filling funnel arranged at a discharge opening of the separating chamber projects into the filling trough.
- the hopper may be in Rejuvenate the direction of the filling tray. The hopper ensures in a simple manner that the liquid deposited in the deposition chamber can flow into the filling trough and over the adjoining filling channel into the dirty liquid tank.
- the contaminant tank can be emptied by removing the filling device.
- the dirty liquid tank has a drain opening which can be closed tightly by means of a lid. The drain opening allows the user to drain the dirty liquid tank without having to remove the aeration device from the dirty liquid tank for this purpose.
- the lid closing the discharge opening is held captive on the housing of the dirty liquid tank.
- the dirty liquid tank can be detachably connected to a base housing of the hard surface suction device which accommodates the suction unit.
- the dirty liquid tank can thus be removed from the basic housing in a simple manner.
- the basic housing can for this purpose have a receiving compartment into which the dirty liquid tank can be inserted.
- the dirty liquid tank can be latched to the base housing.
- the base housing may preferably also accommodate at least one rechargeable battery, in particular one Lithium-ion battery, which can be used to supply power to the suction unit.
- the deposition chamber is preferably designed as a separate component, which is detachably connectable to the suction unit receiving the basic housing.
- a snap or locking connection can be used.
- the separation chamber can be screwed to the basic housing. The separation chamber can thus be separated from the basic housing by the user in a simple manner, for example to clean the separation chamber.
- the suction nozzle with the deposition chamber is detachably connectable.
- the suction nozzle can be connected via a snap or latching connection with the deposition chamber.
- a screw connection can be used.

- liquid deposited in the deposition chamber may initially accumulate in the at least one intermediate storage area which surrounds at least part of the suction channel projecting into the deposition chamber within the deposition chamber. If the Hartvidaug réelle operated at a later time again in an upright position, in which the suction nozzle is arranged above the suction unit, so the first accumulated in the temporary storage area adjacent to the suction channel liquid can flow into the dirty liquid tank.
- the suction unit is preferably in fluid communication with the deposition chamber via a vacuum line, wherein a front end region of the vacuum line protrudes into the separation chamber and is surrounded within the separation chamber in the circumferential direction by an annular intermediate storage region.
- At least one intermediate storage area expediently widens in the direction of the separating device arranged in the separating chamber. This facilitates drainage of liquid that has been temporarily collected in the temporary storage area.
- the provision of at least one intermediate storage area in the deposition chamber makes it possible to operate the hard surface extraction device in any position with respect to the vertical. It is therefore particularly suitable for aspirating a water film from window panes. It can be guided along the window pane by the user in the same way as it is already accustomed to the handling of conventional window cleaning devices, in which liquid applied to the window pane is manually removed from the window pane by means of a puller having a rubber lip. Even if the Hartvidabsaug réelle is transferred to a position above the head, there is no risk that liquid can escape from the deposition chamber or from the dirty liquid tank. Even in such a position, an effective suction flow is formed, so that dirt particles and liquid droplets can be reliably removed from a hard surface.
- the deposition device arranged in the deposition chamber preferably comprises a baffle wall, which is the end arranged in the deposition chamber the vacuum line covered.

- the Hart vomunabsaug réelle 10 is shown in an upright position, in which the suction nozzle 80 occupies a position relative to the vertical position above the suction unit 16. If the hard surface suction device 10 is guided along a surface to be suctioned off in this position, then liquid deposited within the separation chamber 65 can readily reach the drainage opening 101 and the filling device 40 into the dirty liquid tank 25. In this case, the liquid collects in the collecting space 50 arranged below the filling opening 51 of the filling channel 50. The filling level of the dirty liquid tank 25 can be read by the user at the outside marking 52. If the maximum fill level 54 is reached, it can empty the dirty liquid tank 25 via the discharge opening 32.
- the Hartvidabsaug réelle 10 is operated in a horizontal position, in which the suction nozzle 80 is disposed relative to the vertical substantially at the same height as the suction unit 16, or the Hartvidabsaug réelle 10 is operated overhead so that the suction nozzle 80 relative to the vertical below the Suction unit 16 is arranged, so deposited within the deposition chamber 65 liquid can first accumulate in intermediate storage areas of the deposition chamber 33 until the Hartvidabsaug réelle 10 again the upright position shown in Figures 1 and 2 is operated.
- a first staging area 104 is disposed between the front wall 68 of the deposition chamber 65 and the receiving well 75, and a second staging area 105 is positioned between the rear wall 69 of the deposition chamber 65 and the receiving well 75. Both temporary storage areas 104, 105 continuously expand in the direction of the baffle 72.
- the two intermediate storage areas 104, 105 extend in the peripheral direction over a part of the rear end area 87 of the suction channel 81.
- a third intermediate storage area 106 extends annularly over the entire circumference of the pipe socket 96 within the deposition chamber 65.
- the third intermediate storage area 106 also widens continuously in the direction of the impact wall 72.
- the first and second intermediate storage areas 104, 105 receive liquid deposited in the deposition chamber 65, particularly when the hard surface suction device 10 is in the upside-down position, and the third intermediate storage area 106 absorbs liquid deposited in the deposition chamber 65, in particular when the hard surface suction device 10 is lying, without the liquid There is a risk that separated liquid can pass to the suction mouth 83 via the suction channel 81 or to the suction unit 16 via the vacuum line 94. In addition, even with such a position of the Hartvidaugauss 10 reliably suction flow from the suction via the suction passage 81 and the separation chamber 65 to the suction unit 16 is maintained. If the hard surface suction device 10 is then operated again in an upright position, then the intermediate collected liquid from the intermediate storage areas 104, 105 and 106 and passes through the drain opening 101 and the filling device 40 in the dirty liquid tank 25th
- the dirty liquid tank 25 can be aerated in any position of the hard surface suction device 10, so that air can escape from the dirty liquid tank 25 at any time, which can then be sucked out of the separation chamber 65 via the vacuum line 94.
- the Hart vomunabsaug réelle 10 can thus be operated in any position relative to the vertical, wherein in the deposition chamber 33 separated liquid can either pass directly through the filling device 40 in the dirty liquid tank 25 or it is first stored in intermediate storage areas 104, 105 and 106 of the deposition chamber 65 until the Hart vomabsaug réelle 10 again an upright position occupies.
- the intermediate storage areas 104, 105 and 106 may each have a volume of more than 10 ml, in particular a volume of about 20 ml. Regardless of the position that occupies the Hartvidaug réelle 10 relative to the vertical, there is no danger that already in the dirt liquid tank 25 liquid flows out of this again.
- Dirty liquid which is in the upright position of the hard surface suction device in the collecting chamber 55, is rather taken up by the deflection space 56 of the dirty liquid tank 25 when the hard surface suction device is pivoted out of the vertical. Since the volume of the avoidance space 56 is at least as large as the volume of the collecting space 55, the collecting space 55 can be filled to the maximum, without the risk of liquid flowing out of the dirty liquid tank 25.
- the volume of the collecting space may be, for example, at least 100 ml.
