Definitions
- the invention relates to an upholstery nozzle in which on at least one working edge A thread lifter is arranged in the nozzle housing.
- the suction opening is on the two the upholstery nozzle bounding working edges made of inclined bristle fabric Thread lifter arranged.
- the working edges need to attach the thread lifters to be able to be trained accordingly wide. This is a constructional enlargement the upholstery nozzle.
- the invention has for its object a cushion nozzle of the type described Kind in such a way that despite a structural reduction of the upholstery nozzle a better or at least equally good cleaning effect is achieved.
- the solution to the problem is achieved according to the invention in that only one Working edge arranged a thread lifter and on the opposite of this working edge At least one side of the nozzle housing in the area of the working edge there Air inlet opening is provided. Since there is only one thread on one working edge is attached, only this working edge needs to be appropriately wide become. The width of the other working edge, however, can depend on the wall thickness of the Nozzle housing can be reduced.
- the surface to be cleaned by the thread lifter recorded and reversing the direction of movement of the upholstery nozzle stripped fibers become from the air flowing in through the air inlet openings detected and entrained in the suction direction. This prevents the once loosened fibers pressed against the surface to be cleaned by the other working edge become.
- the cleaning effect is at least as good as achieved with an arrangement of two thread lifters.
- Nozzle housing distributes several designed as bores and / or slots Air inlet openings are provided.
- a reduction in fiber absorption when the working edges of the upholstery nozzle sink in in the material of an object to be cleaned is counteracted by the fact that the air inlet openings at least in their position in relation to the working edge in question partially raised as far as possible or in a vertical direction from the working edge Extend as far as that by a cleaning process
- the working edge does not sink completely into the surface of an object to be cleaned
- the air inlet openings are covered by the material of the surface.
- Air inlet openings 5 are provided on the nozzle housing 6 of the upholstery nozzle 1. These air inlet openings 5 can be at different heights compared to the rear Working edge 4 may be arranged. This ensures that when vacuuming a soft surface or a surface with a long pile of air intakes 5 when the working edges 2 and 4 sink into the surface to be cleaned through the soft The surface or the pile should not be covered so far that there is no air left over the Air inlet openings 5 can flow.
- the air inlet openings extend 5 in the vertical direction opposite the working edge 4 as far upwards, that a complete coverage and thus a closure of the air inlet openings 5 when sinking the working edge 4 into the surface to be cleaned by the material of the Avoid surface or the pile of a cushion or carpet surface in any case becomes. This leaves at least a remaining gap of the air inlet openings 5 free the air can flow into the interior of the nozzle housing.
- the bristle direction of the inclined bristle material of the thread lifter 3 is chosen so that at a forward movement of the upholstery nozzle 1 in the direction of the front working edge 2 previously picked up by the thread lifter 3 in the reverse direction of movement Fibers are stripped from the thread lifter 3. These stripped fibers will of the air flowing in via the air inlet openings 5 in the direction of the air flow with a connected to a vacuum cleaner suction pipe coupled connector 7 Upholstery nozzle 1 entrained and transported away. This prevents this from happening once loosened fibers through the rear working edge 4 back to the surface to be cleaned be pressed, which leads to a deterioration in the cleaning result of the upholstery nozzle 1 would lead.
- Thread lifter 3 In addition to the constructional downsizing of the upholstery nozzle 1 as a result of the attachment, only one Thread lifter 3 also results in a cost saving by eliminating the second thread lifter.
