Definitions

  • the present invention relates to a method for cleaning of surfaces on which the surface to be cleaned is cleaned with a Suction device vacuumed and small elements such as Dust and dirt particles, blades of grass, leaves and the like transported into a container of the suction device and there to be collected.
  • the invention further relates to a Suction device for performing the method.
  • the invention also includes lawnmowers with a Collecting container, where the cutting knife as a blower acts to cut grass stalks into the receptacle promote.
  • vacuum cleaners are sometimes considered to be disadvantageous felt that either not at all or difficult to verify is how full the vacuum cleaner bag is, so the vacuum cleaner bag often already exchanged, if they are still are not completely filled.
  • the container In lawnmowers, the container is for the cut Grass mostly designed as a reusable container, so that it is necessary to hold the collecting container at regular intervals to empty.
  • This emptying can, for example, in Biowaste bins take place, however, because they are often already the household waste is filled, emptying often takes place in garbage bags. Transferring to garbage bags or garbage cans is cumbersome.
  • packaging material is also often used here wasted because the garbage bags are also used for Garbage collection can be given if it is not complete are filled.
  • the object of the invention is therefore a method for cleaning of surfaces as well as a suction device for carrying out the Specify procedure that hygienic handling of the Suction device and in particular the container for holding the Ensure sucked-in small elements while saving material are.
  • the method according to the invention is used to achieve this object for cleaning surfaces, characterized in that the Container made of a tubular film attached to a particular annular posture of the suction device is made by removing a section of the tubular film from the bracket peeled off and closed at its peeled end, and that the container through the holder for the tubular film filled through and after filling at its open Side closed and separated from the rest of the tubular film becomes.
  • the containers are thus to be received of the sucked-in small elements such as a Vacuum cleaner bags or a lawn mower container formed from a tubular film.
  • the invention has the advantage that the collected blades of grass can no longer be refilled need, because according to the invention the collecting container already is designed as a film bag. This simplifies handling considerably.
  • Another advantage is that the container is closed can be before it from the rest of the tubular film is separated, whereby a high level of hygiene is achieved becomes.
  • a welding device is expediently used for this purpose used, the two arranged side by side Includes welding units by two in the tubular film welds lying essentially parallel to one another can be produced are.
  • a filled container by at least two parallel to each other Filled welds. This ensures that when closing a filled container at the same time the base for the next film container is made. The filled container is then between the two welds separated from the rest of the tubular film.
  • the Bracket for the tubular film a conical section on, which expands in the pulling direction of the film and its large outer diameter so much larger than the diameter
  • the tubular film is that the tubular film does not have this End slip, but under by an operator slight expansion of the film material pulled off over the end can be.
  • the conical section for executing a Welding process at its axial end of large outer diameter be so resilient that the section for welding the pulled off the bracket Tubular film section can be compressed so that the film material lies flat on one another.
  • the edge of the funnel-shaped section is formed at the axial end of a large outer diameter that the edge when the cone-shaped section is compressed lay flat on top of each other to form a straight line. This ensures that the open end of a filled Container can be welded clean, as is when compressing the funnel-shaped section also that Foil material placed exactly on top of each other.
  • the bracket can with the component that forms the channel, be screwed. Alternatively can the bracket on the component by a plug and Snap connection be attached. This embodiment has the advantage that the bracket is quickly released from the component can be put a new tubular film on the bracket to push.
  • FIG 1 is an embodiment of an inventive Suction device 1 shown for cleaning surfaces, the is designed as a vacuum cleaner. Belongs to the suction device 1 a housing 2, on the underside of rollers and on the A handle 3 and an on / off switch 4 are provided on the rear are. At the front end of the housing 2 is a flexible Suction tube 5 held, the rear end in the housing 2nd protrudes and at the front end of a suction nozzle 6 known Art is attached articulated. In the housing 2 is a Blower 7 provided that only schematically in the drawing is shown and is used in a manner known per se Air and contaminants through the suction pipe 5 into the housing 2 to suck.
  • a Blower 7 provided that only schematically in the drawing is shown and is used in a manner known per se Air and contaminants through the suction pipe 5 into the housing 2 to suck.
  • a conical bracket 8 is attached to the a tubular film 9 is held in a gathered form.
  • the smaller outside diameter d of the holder 8 is smaller than the inner diameter of the tubular film 9, and the larger outer diameter D at the free end of the bracket by so much larger than the diameter F of the tubular film 9 chosen that the tubular film 9 does not have the free end the bracket 8 can slip, but by an operator be pulled off the holder 8 via the lower end can.
  • the bracket 8 is on Suction tube 5 screwed, which is why on the inner surface of the bracket 8 and on the outer surface of the suction tube 5 each thread 10, 11 are provided.
  • the welding device 12 comprises two welding jaws 13, 14, the opposite of each other on the inner wall of the housing 2nd attached and held on telescopic arms 15, 16 by which they inactive between the one shown in Figure 1 Position and the welding position shown in Figure 2 can be moved towards and away from each other.
  • heating wires 13a, 13b, 14a, 14b are provided, which are parallel to each other transversely to the longitudinal direction of the tubular film 9, in the illustrated embodiment in the vertical direction, extend, the heating wires 13a, 13b, 14a, 14b to the two welding jaws 13, 14 in that shown in Figure 2 Interact welding position to create welds.
  • light welding devices can also be used, for example be provided.
  • the tubular film 9, which is gathered is held on the bracket 8, from the bracket 8 to behind against the resistance of the conical bracket subtracted the large outer diameter D. Then will the free end of the removed film section is welded, to form a bag 21.
  • the suction device 2 is switched on via the on / off switch 4 is, the material sucked by the blower 7 conveyed into the bag 21 via the dust nozzle and the suction pipe.
  • the bracket-side can End of the bag 21 are closed.
  • the free end of the bracket 8 is so elastic compliant and especially in the area of his Edge shaped so that the bracket 8 by the welding jaws is squeezed and the edge is underneath Form a straight line flat on top of each other.
  • the film also lies on top of each other and thus the filled bag 21 by the welding device 12 can be welded clean.
  • the vacuum cleaner bags are thus made a tubular film made of a suitable material exists, i.e. has a certain air permeability. This opens up the possibility of different sizes Manufacture vacuum cleaner bags and thus the capacity to adapt to actual needs.
  • the vacuum cleaner bags can be hygienic after the suction device has been operated and can be easily disposed of by being welded shut and separated from the rest of the tubular film, as described above, without the contained in the bag Dust can escape from the bag.
