Definitions

  • the invention relates to a suction nozzle for vacuum cleaner, which can be used universally for sucking smooth floors and textile floor coverings.
  • the basic structure of the suction nozzle includes a suction head, which has a substantially rectangular plan, a sliding sole having at least one suction side delimited bottom suction slot, a Saugrohran gleich Swiss, which is pivotable about a pivot axis to the suction head or to a pivotally connected to the suction head suction channel connected, as well as on the underside of the suction nozzle for sucking smooth floors extendable arrangement of support and sealing elements, the arrangement of support and sealing elements is attached to a vertically adjustable in the suction head support which is actuated by means of a suction element accessible to the switching element.
  • Vacuum cleaner nozzles with universal cleaning properties for cleaning smooth floors and textile floor surfaces are well known.
  • some versions of these nozzles have retractable, bottom-side sealing elements.
  • DE 298 12 377 U1 For example, such a floor nozzle is described.
  • the invention has the object, in a universally applicable to smooth floors and textile floor surfaces suction nozzle with the features described above to improve the coarse dirt-suction properties without having to make significant structural changes to the structure of the suction nozzle.
  • a suction nozzle whose supporting and sealing element, which is arranged in the region of the front side of the suction head parallel to the front side of two arranged on both sides outside, dimensionally stable edge segments for bottom support of the suction head and at least one arranged therebetween, flexible, non-supporting front segment is formed.
  • the switching element of the arranged in the suction head carrier is lowered and are attached to the carrier support and sealing elements on the underside of the suction head extendable.
  • the sliding sole of the bottom surface is raised so that large dirt particles, for example, have the size of a lens or pea, get under the Saugmundkanten be detected by the Saugluftströmung and absorbed by the ground.
  • the Saugmundkanten expediently have a distance to the bottom surface of more than 3 mm, preferably a distance between 5 mm and 10 mm, when the carrier is lowered and the extended support and Sealing elements rest on the floor surface. Moving the coarse dirt particles on the floor or the floor covering is avoided in that the front segment is formed of a soft, flexible material.
  • the front segment of the support and sealing elements consists of a bristle strip with soft bristles, which pass coarse dirt particles.
  • the front segment can also be designed as a flexible plastic lip, which already curves inwards somewhat due to the effect of the vacuum prevailing below the suction head and, as a result of its flexibility, allows coarse particles to pass through.
  • the embodiments of the front segment which preferably has a width of 150 mm to 220 mm, with a soft bristle or as a soft plastic lip are characterized by a good sealing function and give the suction nozzle significantly improved coarse dirt-suction properties.
  • the invention is also based on the consideration that user coarse dirt, which is well visible due to the particle size, will intuitively only take up with a forward movement of the suction nozzle.
  • the user will direct the suction nozzle targeted to the visible coarse dirt and approach coarse dirt particles intuitively with the middle area of the suction nozzle.
  • the edge segments of the arranged in the region of the front of the suction head and parallel to the front support and sealing element may consist of bristle elements with hard bristles, foam elements or sliding elements with a soft, textile support surface, such as nonwoven fabric, felt or plush.
  • the edge segments can have a width of up to 50 mm at the front. They are designed so that the suction head is supported on the front of the ground and the suction mouth edges in the coarse dirt position have a defined and constant distance from the ground.
  • a sliding function is intended in this embodiment, so that the floor covering is protected during processing with the suction head.
  • the edge segments are L-shaped in plan view and have a leg extending along the narrow side of the suction head.
  • This embodiment ensures a more stable guidance of the suction head on the floor covering in the suction-typical reciprocating movements of the suction head.
  • the L-shaped edge segments may also be part of a circumferential support and sealing element.
  • a bristle rim preferably with hard cutlery or a wreath of foam or sliding elements, which may be on the bottom side, for example, with nonwoven, felt, or plush, connected.
  • a one-piece bristle ring represents an advantageous embodiment.
  • the bristle ring has a covering in the region of the front segment with soft bristles and / or bristles which are inserted at a greater distance are on, while the remaining portion of the bristle rim has a dense cutlery, which receives the forces acting on the suction head, has.
  • a suction nozzle which can be connected to a suction tube and a suction hose to a vacuum cleaner.
  • Its basic structure includes a suction head 1, which has a substantially rectangular plan, a bottom sliding sole 2 with a suction slot 4, a Saugrohran gleich Swiss 5, which is connected about a pivot axis movable to the suction head 1 or to a pivotally connected to the suction head suction channel 6 is, as well as an extended at the bottom of the suction nozzle for sucking smooth floors arrangement of support and sealing elements 7, which is actuated by means of a suction head 1 accessible switching element 8 via an adjustable in the suction head carrier.
  • the supporting and sealing elements 7, which consist for example of bristle strips a sufficient distance, preferably a distance between 5 mm and 10 mm of the lower side Saugmundkanten 3 to the bottom surface is adjustable so that even coarse dirt particles are removed from the suction nozzle from the ground can.
  • the supporting and sealing element which is arranged in the region of the front side F of the suction head parallel to the front side, of two mutually outside arranged dimensionally stable edge segments 10, 10 'to the bottom support the suction head and preferably arranged therebetween, a flexible, non-supporting front segment 11 is formed.
  • Fig. 1 is indicated that the front segment 11 is formed of a flexible plastic lip.
  • the front edge segments 10, 10 ' are designed as bristle elements, which have a dense covering of hard bristles and preferably have a width of 10 mm to 30 mm.
  • the underside of the suction head 1 is in Fig. 2 illustrated, wherein the supporting edge segments 10, 10 'are L-shaped and have a leg which extends along the narrow side S of the suction head 1.
  • the bristles of these edge segments are preferably formed of a stiff, hard material, so that the suction nozzle is supported by the extended bristle strips when sucking smooth floors.
  • the front segment 11 which preferably has a width of 150 mm to 220 mm, is formed of a soft plastic and designed so that coarse dirt particles are run over during a forward movement of the suction head and reach into the region below the suction head.
  • the rear sealing element 12 is stiffer and takes with a forward movement of the suction coarse dirt, which has passed under the suction head, but has not been absorbed.
  • the support and sealing elements consist of a bristle rim 13, which extends along the side edges S and the back of the sliding sole.
  • the bristle rim 13 does not have a portion which forms the front segment 11 carrying, soft cutlery on.
  • the soft cutlery forming the front segment 11 is, for example, narrower, whereby the distances between the bristles or bristle tufts 14 may be selected to be greater than in the remaining region of the bristle rim 13.
  • the cutlery forming the front segment 11 is always selected such that coarse dirt particles move forward of the suction head get under the sole and can then be absorbed.
