Definitions

  • the invention relates to a nozzle for a vacuum cleaner with a first air duct section, which is pivotally connected to a second air duct section, wherein one end of the first air duct section defines an outer hinge part, in which an inner joint part of the second air duct section is movably inserted about a pivot axis, and the joint parts are sealed by flexible sealing lips.
  • False air in the context of the present invention refers to air that does not penetrate the suction operation through a suction mouth on the underside of the nozzle, but through cracks and gaps and does not contribute to the cleaning of a floor surface.
  • a nozzle for a canister vacuum cleaner with the features mentioned is from the DE 30 09 648 A1 known.
  • the known nozzle is designed as a double-jointed nozzle, wherein a rear connecting piece is inserted with an inner joint part in an outer joint part formed by a housing channel. Furthermore, on the housing channel another hinged connection provided with a tiltable bottom plate.
  • elastic sealing lips are arranged in each case on the inner joint part, which extend counter to the flow direction of the suction air. Dimensional deviations of the components can be compensated to a certain extent in such an embodiment by a constructive bias of the sealing lips and the elasticity of the material used, but both a high density and a smooth running of the joints must be ensured.
  • the thinly leaking sealing lips are arranged in the region of the articulated joints inside against the flow direction of the suction air, so that their tips are blown by the suction air flow. Due to the negative pressure in the interior of the airways acting on the sealing lips an inwardly directed force, so that between the sealing lips and the respectively associated sealing surfaces, an air gap can be formed through which false air can get into the nozzle.
  • the invention has for its object to provide a nozzle for a vacuum cleaner with at least one articulated connection, on the one hand has a good sealing effect against false air and on the other hand is inexpensive to manufacture.
  • the object is achieved according to the invention, that all provided for the sealing between the first and the second air duct section sealing lips are integrally formed on the outer joint part and the outer surfaces of the inner joint part at least partially surrounded, said free ends of the sealing lips are applied in the use of the nozzle of the ambient pressure and sealingly on the outer surfaces rest against the inner joint part.
  • the invention therefore generally relates to the design of a joint along the airway in the nozzle.
  • the exact arrangement of the hinge connection and the further embodiment of the nozzle are initially not limited.
  • the inventive design of the connection of mutually associated air duct sections is provided at two articulated connections of the nozzle.
  • the outer joint part and the inner joint part each have a rectangular cross-section, wherein the sealing lips formed on the outer joint part abut at least on the upper outer surface and on the lateral outer surfaces of the inner joint part.
  • an axle For connecting the two air duct sections can be provided within the scope of the invention, an axle.
  • the inner joint part can have a continuous sleeve which receives the axle pin and that of one of the sealing lips formed on the outer joint part is sealed.
  • the sealing lips which, starting from the outer joint part up to their free ends, preferably have a length between 4 mm and 10 mm, particularly preferably between 5 mm and 7 mm, can be formed in a particularly simple manner from thermoplastic material.
  • the outer joint part and the sealing lips integrally formed thereon preferably consist of the same thermoplastic material, for example polypropylene, wherein the sealing lips adjoining the outer joint part without restriction can be formed without restriction directly during the shaping of the first air duct section or subsequently added.
  • the first air duct section form a housing channel and the second air duct section a rear connection piece of the nozzle for connecting the nozzle to a suction pipe or a motor housing.
  • the suction air during suction occurs via a suction mouth on the underside of the nozzle and a suction mouth in the Nozzle and is passed through the housing channel to the connector through which the suction air stream leaves the nozzle.
  • the nozzle is designed as a static nozzle in a preferred embodiment of the invention.
  • Static nozzles according to the present invention are nozzles which have no driven cleaning means such as a brush roller. While in non-static nozzles, the cleaning performance is largely determined by the driven cleaning device, this is determined in static nozzles apart from optionally provided on a bottom plate of the nozzle brushes, lips or thread lifter strip significantly by the effective suction air flow and the flow of the suction mouth, so that the avoidance of False air is of particular importance for static nozzles.
  • the nozzle is designed as a double-jointed nozzle.
  • the articulated connection between the housing channel and connector can be formed at a front end of the housing channel a hinge mount in which a connecting portion is mounted with a peripheral protruding, molded sealing projection, wherein the connecting portion fixed to a tiltable with respect to the housing channel bottom plate or opposite the housing channel tiltable suction head is connected.
  • the connector may be connected as a separate part with the bottom plate or the suction head or integrally formed on the bottom plate or the suction head.
  • the angle between the hinge surface defined by the sealing surface and the sealing projection of the connector is comparatively large and is preferably between 40 ° and 140 °, more preferably between 60 ° and 120 °.
  • a sufficient sealing effect between the sealing projection and the joint receptacle can be achieved, in particular, if only comparatively small tilting angles are required and / or if the distance between the sections of the sealing projection and the associated tilting axis is small.
  • the sealing projection may extend continuously circumferentially on the outer surface of the connecting portion, while in the arrangement of flexible sealing lips between the individual lips typically narrow gaps must remain.
  • Fig. 1 shows a nozzle according to the invention 1 for a canister vacuum cleaner, wherein a housing channel 2, a first air duct section and a rear connector 3 with a rotatable Saugrohrability 4 form a second air duct section.
  • the housing channel 2 has at its rear end on an outer joint part 5, in which an inner joint part 6 of the connector 3 is inserted around a pivot axis 8 fixed by an axle 7 movable.
  • the outer joint part 5 and the inner joint part 6 are sealed by flexible sealing lips 9, which are integrally formed on the outer joint part 5 and the outer surfaces 10a, 10b, 10c of the inner joint part 6 surrounded.
  • sealing lips 9 On both the lateral outer surfaces 10a and on the upper outer surface 10b and the lower outer surface 10c of the inner joint part 6 are sealing lips 9, wherein the lower outer surface 10c is formed by a transverse to the direction of the nozzle 1 in the horizontal direction sleeve 11, the the axle pin 7 receives.
  • the sealing lips 9 have up to their free ends a length I between 4 mm and 10 mm, preferably between 5 mm and 7 mm and consist of the same thermoplastic material from which the outer joint part 5 of the housing channel 2 is formed.
  • polypropylene is suitable as a thermoplastic.
  • the nozzle 1 shown in the embodiment is designed as a double-joint nozzle, wherein in addition to the articulated connection between the housing channel 2 and the connector 3 at a front end of the housing channel 2, a hinge seat 12 is formed, in which a connecting portion 13 with an edge projecting, molded Seal protrusion 14 is mounted.
  • the connecting portion 13 is connected by a screw firmly with a tiltable relative to the housing channel 2 suction head 15.
  • the sealing arrangement between the connecting portion 13 and the housing channel 2 is in Fig. 2c and 2d shown.
  • the sealing projection 14 is arranged on the outer surface of the connecting portion 13 continuously circulating and is at an approximately vertical angle ⁇ on the defined by the joint seat 12 sealing surface 16.
  • the Verkipp Scheme between connector 3 and housing channel 2 is over 50 °, is between the suction head 15 and Housing channel 2 to a front tilting axis 17 only one Tilting range of less than 20 ° provided. Since, in addition to the comparatively small tilting area between the suction head 15 and the housing channel 2, the distances r1, r2 from the front tilting axis 17 to an upper portion and a lower portion of the sealing projection 14 are small, a very good sealing effect is achieved by the sealing projection 14 molded on the edge reached.
  • the nozzle 1 is characterized with respect to the seal by a low tendency to wear, so that the good suction properties of the nozzle 1 are maintained even after a long service life.
  • the illustrated nozzle 1 is formed as a universal floor nozzle with a suction mouth 18 and an extendable bristle rim 19 on the underside of the suction head 15. To ensure easy guidance of the nozzle 1 lateral rollers 20 are arranged at the rear.
