Definitions

  • the invention relates to a vacuum cleaner with a housing, a suction unit arranged therein and one entering the housing and via a dirt collecting container and a separator with the suction side the suction unit in connection with the suction line, the closed dirt collector can be inserted into the housing and used in the Position sealed via a suction opening with the Suction line and sealed with a suction opening the suction side of the suction unit is connected, the dirt collecting container partially with a Liquid is filled into one of the suction opening inlet line reaching into the liquid flows out, and being above the liquid filling Baffles are arranged for the by the Liquid-guided suction flow between the liquid surface and the suction opening one more time form redirected flow path.
  • Such a vacuum cleaner is for example in the US 2,539,867 described, opens in this vacuum cleaner an entry line into a liquid filling Dirt collecting container, this junction takes place just below the surface of the liquid, so that the suction flow introduced into the liquid only for a short time comes into contact with the liquid, the deposition of dirt particles from the suction stream is not can be done completely in any case.
  • the invention is based on this prior art the task is based on a generic Vacuum cleaner to achieve an optimal separation result and to get a device with a simple structure.
  • This task is the beginning of a vacuum cleaner described type according to the invention solved in that the junction of the entry line into the liquid is covered by a hood, through which the Entry line leads that one-sided into the Immerses liquid and its opposite end is arranged outside the liquid, and that itself the hood on its immersed in the liquid Extends to the bottom of the dirt container, so that in this area the in the liquid incoming suction stream cannot pass through.
  • such a vacuum cleaner can be used in the simplest Be regenerated in such a way that the closed dirt collector from the housing removed, especially pulled out, and emptied is, for example through a special emptying opening, and that fresh liquid is poured in preferably water.
  • a complicated change filter bags etc. is no longer necessary, and through the all-round training of the Dirt collecting container is this with its liquid filling easy to use, because the dirt collector as a separate unit in the housing inserted and easily out of this is removable.
  • the dirt collecting container can, for example, essentially be cuboid and forms a bucket-like vessel. This can be used to handle it Be provided with a handle, for example a swivel handle like a bucket.
  • the dirt collecting container has a lower part open at the top, which is closed with a removable lid is. This facilitates the filling and emptying of the Dirt collecting container and its cleaning.
  • the suction opening is a preferred one Embodiment in the lid.
  • This filter can be designed as a removable insert his.
  • the filter is connected to a seal Connects suction line leading suction line of the suction unit.
  • the filter has a gap between the suction line on the one hand and the suction opening of the dirt collection container sealed bridged. This gives you a control for the functional Insert the filter. If the filter is accidentally missing, there is a leak in the area of the gap, and the vacuum cleaner doesn't work in the desired way. The user is thus at the lack of the filter.
  • the dirt collector at least in the area of Suction opening opposite the insertion direction of the Dirt collecting container inclined slightly sloping is so that a seal surrounding the suction opening only towards one another at the end of the insertion movement Sealing leading suction line of the suction unit of the suction unit invests.
  • that the arranged on the top of the dirt collector Suction opening upstream of a suction shaft is that completely covers the suction opening and laterally offset from this to form an inlet opening is open on one side.
  • Such an intake duct redirects the suction flow inside the container and forms an impact surface with its underside, at which the suction flow of entrained liquid particles is separated.
  • the intake shaft extends over the entire width of the container.
  • the intake duct can be on the side on its open side protruding sealing strips wear that on the inner wall of the dirt collector. So that is ensured that the suction flow through the inlet openings the intake duct must pass through and does not flow past these on the side.
  • the underside of the intake shaft can preferably be flat and substantially parallel to the top of the dirt collection container.
  • the suction duct can be connected to a removable one Sealed dirt collection container the lid.
  • the entry line is preferably on one side of the Dirt collecting container near the rear wall arranged and opens approximately in the middle of the container into the liquid.
  • the hood is preferably arcuate in cross section trained and with its concave side of the junction facing.
  • the hood can differ from the junction in particular so far into the inside of the dirt container extend that it covers the suction opening. Thereby forms it together with the underside of the intake duct a multiple angled flow path out.
  • the hood over extends the entire width of the dirt collecting container.
  • the interior covered by the hood at least then the one immersed in the liquid Area of the hood by two vertical partitions in a central chamber and divided into two lateral chambers becomes.
  • this central chamber comes out of the Intake line exiting suction flow into the liquid one, and this central chamber forms the actual one Turbulence space for the suction flow, its width through the vertical partitions in the desired Way can be chosen.
  • the side chambers are narrow compared to the central chamber.
  • the side chambers can only Cover 10% of the total width of the hood.
  • the hood is in the area the lateral chambers below the liquid level has at least one passage each.
  • This Passage serves to balance the liquid level on both sides of the hood so that in the area behind the hood, i.e. in the turbulence space facing away from the hood Part of the hood no accumulation of liquid occurs, but the fluid level as a whole Dirt collector is always the same.
  • the vertical partitions can cover the entire Extend hood interior, at a preferred Embodiment is provided, however, that the vertical partitions only about half of the Extend hood length.
  • hood is removable is inserted in the dirt collector. This enables careful cleaning of all parts the dirt collector.
  • the hood can carry a handle.
  • the hood in the dirt collector can be provided that the side walls of the dirt collector Have contact areas for the hood.
  • Such contact surfaces for the hood can also the entry line may be arranged, in this case the contact surfaces are preferably as upwards open grooves formed into the edge of the hood intervenes.
  • the free edge of the hood facing front part of the hood can be pivoted at the rear Part of the hood is held, preferably over a film hinge.
  • This configuration is special cheap if the hood is permanently in the dirt collector is fixed because the swinging up of the front part of the hood gives access to that under the Part of the dirt collecting container lying open and is therefore a good cleaning option.
  • the flow cross-section preferably takes between neighboring baffles in the direction of flow, so that the flow rate increases, and this leads to an optimal separation of entrained ones Liquid particles.
  • the side wall can be partially be stiffened, for example by stiffening ribs or by greater wall thickness, so that despite the deformable side walls, a stable overall structure of the dirt collector is.
