Definitions

  • the invention relates to a Staubsauger foundeddüse according to the preamble of claim 1.
  • canister vacuum cleaners In so-called canister vacuum cleaners, the motor, blower, filter unit and electronic devices are arranged in a housing, which is usually mounted on rollers.
  • An often telescopically adjustable in length suction pipe is connected at one end by means of a flexible suction hose to the housing or the blower of the vacuum cleaner and has at its other end to a floor nozzle, which comes into contact with the surface to be cleaned.
  • a second design form the so-called hand vacuum cleaner.
  • the suction pipe is rigidly connected to the vacuum cleaner housing.
  • engine, blower, electrical and filter unit are housed in the housing.
  • This additionally has on the side opposite the suction pipe connection on an extension of the suction pipe attached handle for handling.
  • the negative pressure generated by the motor and blower is applied to the surface to be cleaned.
  • These are usually either hard, smooth surfaces of floor coverings such as parquet, PVC, stone, etc., or textile surfaces such as carpets, furniture upholstery or the like.
  • the different nature of the surface makes partially conflicting demands on the functionality of the floor nozzle.
  • the invention is based on the generic Staubsauger convinceddüse in that the edge radius of the front suction mouth edge is smaller than the edge radius of the rear suction mouth edge.
  • a forward sliding movement which is also referred to as a forward stroke, opens the front edge of the suction mouth, the carpet or the carpet fibers. This allows for dust collection from deeper areas of the carpet.
  • the rear suction mouth edge slides over the carpet during the forward stroke. The larger the radius of the rear suction mouth edge, the better the sliding properties and the lower the required pushing force.
  • the invention is further developed in a particularly advantageous manner in that the edge radius of the front suction mouth edge is between 0.5 mm and 1 mm and that the edge radius of the rear suction mouth edge is between 1 mm and 3 mm.
  • edge radii are feasible within the scope of a practical design of the nozzle sole, and they lead to the desired improvements with regard to the dust absorption and the pushing force.
  • the invention is developed in an advantageous manner by the fact that during a sliding movement the front suction mouth edge and the rear suction mouth edge are to be cleaned with a sliding movement.
  • the front suction mouth edge In a pulling movement, the front suction mouth edge is in contact with the surface to be cleaned and the rear suction mouth edge is not in contact with a surface to be cleaned.
  • the so-called backward stroke generally only the front suction mouth edge is in contact with the surface, since the rear suction mouth edge is lifted from the carpet by pulling on the handle. It is therefore without any disadvantage to provide the rear suction mouth edge with a large edge radius, since a combing effect of the rear suction mouth edge is not provided anyway.
  • the Staubsauger foundeddüse invention may be formed so that it has a steel sole.
  • the Staubsauger foundeddüse be designed in such a way that it has a plastic sole.
  • Figure 1 is a perspective view of the underside of an inventive
  • the Staubsauger foundeddüse 10 shown in Figure 1 has in the region of its sole 12 a suction mouth 14, which serves as an inlet opening for air and entrained by the air dirt particles.
  • the Staubsauger foundeddüse 10 further has a bristle strip 20 and one or more thread lifter 22 with regard to the dirt pickup.
  • the suction mouth 14 is equipped according to the invention with two suction mouth edges 16, 18, wherein the front suction mouth edge 16 has a smaller edge radius than the rear - A -
  • Suction mouth edge 18 has. This has the consequence that on the forward stroke, due to the small edge radius, improved combing of a carpet takes place, so that increased dust absorption is made possible.
  • the rear suction mouth edge 18 with a small edge radius slides with little resistance over the carpet.
  • the rear suction mouth edge 18 is lifted off the carpet, and the front suction mouth edge 16 slides over the surface with a sufficiently low resistance due to the lower forces between the floor nozzle 10 and the surface compared to the forward stroke.

Abstract

Suceur (10) à tapis et sols durs pour un aspirateur, qui comporte une bouche d'aspiration (14) ménagée dans une base (12) du suceur et servant d'orifice d'entrée pour l'air et pour les particules de poussière transportées par l'air, ladite bouche d'aspiration comportant, par rapport à un mouvement de poussée, une arête avant (16) et une arête arrière (18). Pour améliorer les propriétés de glissement de ce suceur pour aspirateur et la capacité de capture de la poussière sur les tapis, le rayon de l'arête avant (16) est inférieur au rayon de l'arête arrière (18).
