Description

  • The invention relates to a floor nozzle for a vacuum cleaner, a vacuum cleaner and a method for producing a floor nozzle for a vacuum cleaner.
  • State of the art
  • As vacuum cleaner nozzles are usually before ground nozzles with a sliding sole and a suction mouth with one or more Saugmundkanten. The Saugmundkanten are usually straight or curved edges of the sole. Sliding soles / Saugmundkanten are usually made of plastic or metal. Important requirements for the sliding sole are a very good dimensional accuracy, d. h., The Saugmundkanten should be straight and the sole sole as a whole, and a good strength, d. h., the sliding sole should pass endurance tests on carpet (abrasive wear) and should not break when dropped. Concerning the geometries, for example, the following variants of Saugmundkanten are common: straight Saugmundkanten or Saugmundkanten with free contour (curved), Saugmundkanten with different transition radii, single or double Saugmundkanten (arranged one behind the other) and Saugmundkanten formed by flexible sealing lips.
  • With the introduction of the energy label for vacuum cleaners in September 2014, cleaning classes for dust absorption values were defined. To achieve better cleaning classes, the floor nozzle can be "aggressive", d. H. be designed without edge radii of Saugmundkanten the suction mouth of the floor nozzle. To achieve a better protection of the soil, the floor nozzle alternatively "normal", d. H. be designed with edge radii of Saugmundkanten the suction mouth of the floor nozzle.
  • With floor nozzles for a vacuum cleaner for sucking on carpets, the sliding sole is moved over the carpet. The front in the direction of movement, provided with a large radius suction mouth opens the carpet pile and the upper dirt particles can be removed by the air flow. The rear, in the direction of movement provided with a large radius suction mouth edge does not open the carpet pile, but slides due to the radius well over the carpet pile and produces a low resistance to movement.
  • With floor nozzles for a vacuum cleaner for sucking on hard floor, a distance between the hard floor and the hard sliding sole can be created by bristle strips (or rollers, etc.), so that the sliding sole does not touch the hard floor to be cleaned.
  • The invention has for its object to provide an improved floor nozzle for a vacuum cleaner, an improved vacuum cleaner and a method for producing an improved floor nozzle for a vacuum cleaner.
  • According to the invention this object is achieved by an improved floor nozzle for a vacuum cleaner, a vacuum cleaner and finally a method for producing an improved floor nozzle for a vacuum cleaner with the features of the main claims.
  • Advantageous embodiments and further developments of the invention will become apparent from the following subclaims.
  • The advantages achievable with the invention are that good dust absorption values or a good label classification can be achieved with the greatest possible protection of the material. The durability of both the nozzles and the carpet or hard floor is not adversely affected. Furthermore, such an improved floor nozzle can be easily and inexpensively manufactured.
  • A floor nozzle for a vacuum cleaner has a sliding sole for sliding over a floor, wherein the sliding sole has at least one suction mouth for receiving dirt particles, wherein the sliding sole has at least one substantially tapered suction mouth edge at an open end of the suction mouth, characterized in that the Saugmundkante a material that differs from a material of the sliding sole.
  • A vacuum cleaner may be a cleaning device that produces a negative pressure by means of a blower in a vacuum cleaner body lying on a floor to be cleaned, wherein the negative pressure draws air into the vacuum cleaner body via a vacuum cleaner hose and a floor nozzle arranged at the end of the vacuum cleaner hose. The vacuum cleaner can also be designed as a hand vacuum cleaner, which has only contact via the floor nozzle with the floor to be cleaned. The floor nozzle rests on a floor to be cleaned and can be moved over it. The part of the floor nozzle that slides over the floor is called a sliding sole. A suction mouth is an opening of the sliding sole, through which the air reaches the floor nozzle. The portion of the suction mouth that merges into the sliding sole is called the suction mouth edge.
  • By such a floor nozzle presented here, there is an advantage in that the Saugmundkante depending on the nature of the floor to be cleaned, such as a carpet or a hard floor, a different, adapted to the nature of the soil material may have. Through the use of a second material component, an optimal material pairing with a low coefficient of friction between a hard suction mouth and a carpet come to fruition without worsening the requirements of strength and shape or to cause high wear of the Saugmundkanten and the floor covering. The solution without edge radii can pass the dust absorption tests in the laboratory.
  • By using a second material component, the suction mouth edge can be made soft for cleaning a hard floor. This does not damage the bottom and nozzle even when in contact with an uneven hard floor.
  • The suction mouth edge may, according to one embodiment, comprise a softer material than the material of the sliding sole. Such a condition of the suction mouth edge is particularly advantageous for use on hard floors. On contact with the hard floor, the sliding sole may yield due to a softer texture and prevent scratching of the floor or scraping noises. A suction mouth made of a soft material can reduce the distance to the ground, increase the tightness and thus also the dust absorption.
  • According to one embodiment, the suction mouth edge may have a material which is the same hardness or harder than the sliding sole. Such a condition of the suction mouth edge is particularly advantageous for use on carpets. An upstream in the direction of movement of the floor nozzle hard Saugmundkante can open the carpet fibers of the carpet very effectively, so that dirt particles from the deeper layers can be removed by the air flow.
  • The suction mouth edge can, in a position of the sliding sole facing a floor to be cleaned, form the floor element closest to the floor of the sliding sole. Such an arrangement allows the suction mouth edge, in the variant with a hard suction mouth edge for a carpet floor, to penetrate particularly deeply into the carpet fibers. In the version with a soft suction mouth edge for a hard floor with cracks, the suction mouth edge can be arranged particularly close to the ground surface, which can result in improved dirt pickup.
  • In a position facing a floor to be cleaned, the free ends of a spacer of the floor nozzle, such as bristles or rollers attached to a peripheral edge of the sliding sole, may rest on the floor, with the free end of the suction mouth edge at a very small distance from the floor above the floor can be placed floating. The high sealing from the bottom to the suction mouth edge is advantageous for dust absorption from deeper-lying cracks. Even on uneven ground there is no danger of scratching the floor due to the soft suction lip.
  • According to one embodiment, the suction mouth edge of the floor nozzle can be made in one piece with the sliding sole. An integrally manufactured sliding sole with suction mouth edge can firmly fix the suction mouth edge to the soleplate without any further fastening aids.
  • The suction mouth edge integrally manufactured with the sliding sole can be produced by a two-component injection molding process. The 2K injection molding process (2K = two-component) is suitable for combining two different materials, for example for the production of 2K suction mouth edges, ie a floor nozzle with 2K suction mouth particularly, since the 2K injection molding process firmly connects two different materials.
  • The suction mouth edge and / or the sliding sole may for example be made of a plastic material. Plastic is stable, light and cheap to manufacture. For a 2K injection molding, for example, combinations of plastic are particularly suitable because they are easy to process.
  • The suction mouth edge and / or the sliding sole may alternatively be made of a material differing from a plastic material, in particular the suction mouth edge and / or the sliding sole may be made of wood or metal. Combinations of plastic and wood or of plastic and metal can give the sliding sole and / or the suction mouth edge a particularly high stability.
  • The suction mouth edge may be upstream of the suction mouth in a provided direction of movement of the floor nozzle. An intended direction of movement is a direction in which the floor nozzle is moved during normal use preferably or with high frequency. In the variant with a hard suction edge for a carpet, an upstream suction mouth edge can penetrate into the carpet fibers of the carpet, so that dirt can be sucked from deeper levels of the carpet. In the variant with a soft suction mouth edge for a hard floor, the distance to the floor in the direction of movement of the floor nozzle can be reduced which can result in improved dirt pickup.
  • According to one embodiment, the open end of the suction mouth may have a second substantially tapered suction mouth edge, the second suction mouth edge having a material different from a material of the sliding sole. A second soft suction mouth edge may, in a position facing the floor to be cleaned, reduce the distance to the floor surface at a further location, which may result in improved dirt pickup.
  • The suction mouth edge and the second suction mouth edge may, for example, be arranged on opposite sides of the suction mouth. Such positioning of the Saugmundkanten allows even during backward movements of the floor nozzle an equal cleaning result of the soil as during forward movements of the floor nozzle.
  • A corresponding vacuum cleaner has a floor nozzle presented here. Such a vacuum cleaner may have a firmly integrated suction mouth edge with a softer or a harder material than the sliding sole for different requirements of the soil to be cleaned due to the one-piece, but different materials having sliding sole with suction mouth.
  • A method of manufacturing a floor nozzle for a vacuum cleaner comprises the following steps:
    Producing a sliding sole for sliding over the ground, the sliding sole having at least one suction mouth for receiving dirt particles; and
    Attaching at least one substantially tapered suction mouth edge to the sliding sole at an open end of the suction mouth, characterized in that
    in the step of attaching, attaching the suction mouth edge using a material different from a material of the sliding sole.
