Definitions

  • the invention relates to a portable Hart vomabsaug réelle with a suction nozzle and a suction unit which is in flow communication with the suction nozzle for sucking a liquid-air mixture from a hard surface, and with a separator for separating liquid from the liquid-air mixture and a dirty liquid tank for receiving the separated liquid.
  • Hartvidabsaugowski By means of such Hartvidabsaugowski a liquid from a hard surface, such as a window, can be sucked.
  • a suction flow is generated by means of a suction unit, so that a mixture of liquid and air can be sucked in via the suction nozzle.
  • the liquid can be separated by means of the separator from the mixture of liquid and air and transferred to a dirty liquid tank.
  • the Hartvidabsaugowski are designed to be portable, so that they can be performed in a simple manner by the user manually on the hard surface to be sucked.
  • Hartvidabsaugowski are for example from the EP 0 663 176 B1 and the US Pat. No. 6,691,369 B1 known.
  • Hartvidabsaug réelle disclosed the deposition of liquid from the liquid-air mixture takes place directly in the dirty liquid tank. This has the consequence that the degree of separation is dependent on the liquid level in the dirty liquid tank.
  • the suction flow caused by the suction unit changes. With increasing filling of the separation tank there is a risk that the Suction flow is reduced and thereby only a smaller amount of liquid can be sucked from the hard surface.
  • the Hart vomunabsaug réelle which in the US Pat. No. 6,691,369 B1 also has the disadvantage that it can be operated only in a predetermined position relative to the vertical, otherwise the connection between the suction nozzle and the suction unit is interrupted by a float. If the Hart perennialabsaug réelle operated overhead, such that the suction nozzle is arranged relative to the vertical below the suction unit, so there is a risk that aspirated from the hard surface liquid again emerges from the suction port of the suction nozzle. The user must therefore make sure that he operates the hard surface suction only in a predetermined position. This complicates the suction of hard surfaces that are difficult to reach by the user, such as the windows of sloping obliquely to the vertical roof windows.
  • Object of the present invention is to develop a portable Hart vomabsaug réelle of the type mentioned in such a way that it forms a constant suction regardless of the level of Schmutz problemkeitstanks and can be operated in any orientation relative to the vertical.
  • a deposition chamber is arranged, which receives the separator and the via a suction line with a suction of the suction nozzle and a vacuum line with the suction unit is in flow communication and which is connected via a drain opening with the dirty liquid tank, wherein the mouth areas of the suction and the vacuum line within the separation chamber in the circumferential direction are at least partially surrounded by intermediate storage areas for separated liquid.
  • the deposition of liquid from the aspirated liquid-air mixture takes place in a deposition chamber, which is connected via a drain opening with the dirty liquid tank.
  • the extracted liquid collects without thereby affecting the suction flow caused by the suction unit.
  • the suction flow thus does not reach through the dirty liquid tank and is thus independent of the level of the dirty liquid tank.
  • the separation chamber is in fluid communication with the suction mouth of the suction nozzle via a suction line, and the separation chamber is connected to the suction unit via a vacuum line.
  • the mouth region of the suction line which opens into the deposition chamber is surrounded within the deposition chamber by at least a portion of its circumference by a buffer region for separated liquid.
  • this mouth region is surrounded at least partially within the deposition chamber in the circumferential direction by a buffer storage area for separated liquid.
  • a buffer storage area for separated liquid is surrounded at least partially within the deposition chamber in the circumferential direction.
  • the Hartvidabsaug réelle invention can be operated in any orientation relative to the vertical. If the Hartvidabsaug réelle example, operated such that the suction nozzle relative to the vertical below the suction unit a suction flow can nevertheless form and liquid can be deposited in the separation chamber by means of the separation device, wherein the separated liquid can first accumulate in the at least one intermediate storage area surrounding the opening region of the suction line within the separation chamber.
  • the Hart vomunabsaug réelle invention is thus characterized by a constant Absaug chapter, regardless of the level of the dirty liquid tank and regardless of the location that occupies the Hart vomabsaug réelle relative to the vertical. It is therefore particularly suitable for aspirating a water film from window panes. It can be performed by the user in the same way along the window, as he is already used to the handling of conventional window cleaning equipment, where applied to the window glass liquid by means of a Rubber-removing puller is removed manually from the windowpane.
  • the separation device forms a baffle within the separation chamber, which is arranged between the mouth regions of the suction and the vacuum line.
  • the deposition chamber is subjected to negative pressure during operation of the hard surface suction device, so that the aspirated via the suction nozzle liquid-air mixture is sucked into the deposition chamber.
  • the mixture flows through the mouth region of the suction line and then impinges within the deposition chamber on the baffle wall, at which liquid is deposited.
  • the sucked air flows around the baffle wall and can then be sucked out of the separation chamber on the side of the baffle wall facing away from the mouth region of the suction line via the mouth region of the vacuum line.
  • the baffle wall is convexly curved in the direction of the mouth region of the suction line. This has the advantage that the sucked air can flow around the baffle with low flow losses in order to reach the mouth region of the vacuum line.
  • a particularly large separating effect is achieved in an advantageous embodiment in that the baffle wall covers the mouth opening of the vacuum line.
  • a further increase in the separation effect can be achieved by arranging a baffle plate at a distance from the mouth opening of the suction line.
  • the aspirated liquid-air mixture at the mouth opening of the suction line first meets a baffle plate, in order then to reach the interior of the deposition chamber, in which the separation device is arranged. A portion of the sucked liquid is already deposited on the baffle plate, another part is then separated by means of the separator of the sucked air.
  • the baffle plate is planar and aligned obliquely to the longitudinal axis of the suction line. Flow losses of the suction flow can be kept low, and entrained liquid droplets can be reliably deposited.
  • the mouth region of the suction line dips into a receiving shaft of the separation chamber projecting into the separation chamber, the receiving shaft and the outer walls of the separation chamber forming at least one of the intermediate storage regions for separated liquid.
  • the mouth region of the suction line is received by the receiving shaft and held in this reliable. The risk of mechanical damage to the suction line is thereby reduced.
  • Between the receiving shaft and the outer walls of the deposition chamber at least one of the intermediate storage areas is formed, in which separated liquid can accumulate with appropriate alignment of the hard surface suction device, in particular when the Hard surface suction is operated overhead, that is, when the suction nozzle occupies a position below the suction unit relative to the vertical.
  • the hard-surface suction device is operated upright again at a later time, so that the suction nozzle is arranged above the suction unit, the liquid accumulated in the at least one intermediate storage area between the receiving shaft and the outer walls of the separation chamber can flow into the dirty liquid tank via the discharge opening.
  • the at least one buffer storage area which is arranged between the receiving shaft and the outer walls of the separation chamber widens in the direction of the separation device, because this facilitates the outflow of liquid accumulated in the intermediate storage area.
  • a continuous expansion of the at least one temporary storage area, which is arranged on the outside of the receiving shaft, has proven to be particularly favorable.
  • the mouth region of the vacuum line is preferably formed by a pipe projecting into the deposition chamber.
  • the pipe section can be completely surrounded within the deposition chamber in the circumferential direction by one of the intermediate storage areas for separated liquid, that is to say the opening area of the vacuum line is preferably surrounded by an annular intermediate storage area.
  • the at least one intermediate storage area which at least partially surrounds the mouth region of the vacuum line in the circumferential direction expands in the direction of the separating device in an advantageous embodiment. This facilitates the drainage of accumulated liquid from the staging area. In particular, a continuous expansion has proven to be advantageous.
  • the Hart vomabsaugONE invention can be worn by the user with one hand. It is advantageous if the vacuum line passes through a handle of Hart Jerusalemabsauguzes.
  • the handle may preferably be completely encompassed by the user. This facilitates the guiding of the hard surface suction device along the hard surface to be suctioned off, in particular along a window pane or even a glass door.
  • the Hartvidabsaug réelle has a suction unit receiving the base housing, and the deposition chamber is detachably connected to the base housing.
  • a snap or locking connection can be used.
  • the deposition chamber can thus be easily separated from the user from the main body, so that the separation chamber can be cleaned.
  • a screw connection can be used.
  • the dirty liquid tank is made separable so that it can be separated from the user by the remaining hard surface suction device, for example to empty the tank.
  • the dirty liquid tank with the basic housing of Hart vomabsaugilless releasably connected.
  • a snap or latching connection can be used; alternatively, in particular, a screw connection is also possible.
  • the suction nozzle is releasably connected to the deposition chamber.
  • the suction nozzle can be connected via a snap or latching connection with the deposition chamber.
  • a screw connection may be provided.
  • the Hart vomicoabsaug réelle has a suction unit and in particular also rechargeable batteries receiving basic housing with a designed as a separate component separation chamber is detachably connected, which in turn can be releasably connected to a suction nozzle and the suction line comprehensive suction nozzle, said in addition, a dirty liquid tank which can be detachably connected to the base housing and / or to the deposition chamber is provided.
  • a drainage funnel is arranged in a preferred embodiment of the invention for transferring separated liquid from the separation chamber into the dirty liquid tank.
  • the drainage funnel narrows in the direction of the dirty fluid tank. This simplifies the drainage of separated liquid into the dirty liquid tank.
  • the air within the contaminant tank In order for liquid to flow into the contaminant tank during operation of the hardfloor aspirator, it is necessary for the air within the contaminant tank to exit the tank can.
  • the dirty liquid tank can be ventilated via the ventilation channel.
  • the ventilation duct projects into the separation chamber, so that liquid deposited in the separation chamber flows around the ventilation duct and can pass unhindered into the dirty liquid tank and at the same time air can escape from the dirty liquid tank via the ventilation duct.
  • a drainage channel through which the dirty liquid tank is connected to the separation chamber projects into the dirty liquid tank. If the Hartvidaug réelle operated overhead, such that the deposition chamber is disposed below the dirty liquid tank with respect to the vertical, the liquid can accumulate within the dirty liquid tank in the area surrounding the drainage channel, without the risk that the liquid from the dirty liquid tank emerges.
