Definitions

  • the invention relates to a hose arrangement for a vacuum cleaner, which automatically its length changing suction hose with grooves on its outer circumference has, which is automatically extended at least in a partial area is in which arrangement a support member is also provided, which for guiding one coupled to it and fluidly connected to the suction hose Suction mouthpiece is used and on which the suction hose is guided supported at least over part of its length, the Suction hose by means of a suction hose against an automatic change in length securing retaining element can be blocked in its shortened position on the support part.
  • Such a hose arrangement is already known from WO-A-8 607 247.
  • the hose can be slipped over the outer circumference of the support part or slide into the inside of the support part.
  • the end pieces of the Hose connected to the end pieces of the support part.
  • EP-B-O 388 676 is a handheld vacuum cleaner, in particular a brush vacuum cleaner is known in which the suction air from a suction nozzle arranged in the bottom region a hand suction hose as a riser in an upper area of the vacuum cleaner housing to be led.
  • the hand suction hose is in the area facing the suction nozzle arranged detachably so that it can be removed for secondary suction work.
  • the hand suction hose is also equipped with an extension hand suction pipe coupled. This hand suction pipe is detachably attached to the housing of the hand vacuum cleaner and can be removed to carry out secondary suction work.
  • the hand suction hose is telescopic into that Hand suction tube inserted, which is a magazine-like receptacle for the hand suction hose forms so that it is long hand suction hose when performing Suction in floor suction mode is not a hindrance.
  • a suction hose is usually at one end the suction opening of the vacuum cleaner housing and with its other end at one Intake pipe connected.
  • the suction pipe thus serves to guide a plugged onto it Suction mouthpiece and for fluid connection of the suction mouthpiece with the suction hose.
  • the invention has for its object a hose assembly for a vacuum cleaner, in particular to create a vacuum cleaner, which can be easily on Can attach the support part.
  • the shortening process of the suction hose can be done with the help of the vacuum cleaner generated negative pressure are carried out that in the area of the Suction mouthpiece fluidly connected hose end on the air supply locking closure member is provided.
  • suction tube that receives the suction hose as a support part provided.
  • a suction pipe makes the suction hose particularly good secured against lateral evasion.
  • Support part is telescopically adjustable.
  • the suction hose can through the Vacuum initially contracted in the area of the full length of the support part. become. Then the telescopic support part together with the Suction hose can still be pushed together accordingly.
  • a contamination of the outside of the part running in the intake manifold of the suction hose is avoided if the suction hose is in the area of the Suction mouthpiece coupled end of the suction pipe firmly connected to the suction pipe is.
  • the dirt-laden suction air is in this case on the entire route the suction hose, so that contamination of the outside of the suction hose not possible.
  • the suction hose can be used for such Formation of the hose assembly pulled out of the intake manifold as far until its end reaches the corresponding end area of the suction pipe.
  • Contamination of the outside of the insertable part of the Suction hose is avoided in that a surrounding the suction hose Foil sleeve is provided, which when inserting the suction hose into the suction tube in the between the outer circumference of the suction hose and the inner circumference of the Exhaust pipe existing space is longitudinally extendable.
  • suction hose is self-acting in a partial area lengthening and trained in a further sub-area as self-shortening is. In this way you can take advantage of both types of automatic length change a suction hose can be used.
  • the vacuum hose can be contracted in a simple manner are triggered by the fact that as a closure member one of one with the intake manifold connected handle is provided as a remotely operated valve. So the user can a vacuum cleaner after completion of the suction work while still running Vacuum cleaner control the valve in its closed position, so that then in the Suction hose which becomes effective high vacuum a contraction of the suction hose he follows.
  • suction hose 4 is designed as an automatically extending hose.
  • this suction hose 4 has an integrated in its hose wall as Compression spring acting coil spring.
  • the support part 3 is designed as a telescopically insertable suction tube 5.
  • the suction hose 4 is inserted so that its corresponding Hose end 6 in the area of the end coupled to a suction nozzle 7 8 of the suction pipe 5 lies.
  • the hose end 6 is fixed in this area with the Suction pipe 5 connected.
  • a valve 9 is switched.
  • This valve 9 can, for example, from the handle 10 of the Suction pipe 5 can be operated remotely. Details for such remote control are in not shown in the drawing.
  • On the handle 10 of the suction tube 5 is also a cross locking fingers displaceable to the longitudinal axis of the suction pipe 5 or suction hose 4 11 attached. This locking finger 11 can in the on the outer circumference of the suction hose 4 existing, thread-like grooves 12 inserted become.
  • the locking finger 11 is located while performing suction work. out of engagement with the grooves 12, so that the suction hose 4 automatically on its can stretch full length.
  • the compressible suction hose 4 either by hand or by the force of the vacuum in the intake manifold 5 inserted or retracted.
  • the valve 9 is closed while the vacuum cleaner is still running.
  • the in the wall of the Suction hose 4 incorporated spiral spring is so in terms of their spring constants designed that a compression of the suction hose 4 by the force of the full Negative pressure is possible due to the prevailing during suction operation Vacuum, however, does not significantly shorten the suction hose 4 becomes.
  • the suction hose 4 can also by hand in that Suction pipe 5 are pressed in. Then the locking finger 11 becomes corresponding actuated so that it engages in one of the grooves 12 and thus the suction hose 4th blocked in its compressed position.
  • the suction tube 5 is designed as a telescopic tube, as shown in the drawing is indicated, there is the possibility of the suction hose 4 first in the its extended position located suction pipe 5 to pull in by the vacuum force and to lock in this position by means of the locking finger 11. After that can by pushing the telescopic tube together a corresponding Shortening the hose arrangement can be made. The one after a shortening of the suction hose 4 still outside of the suction pipe 5 remaining length the suction hose 4 allows space-saving storage of the hose arrangement and vacuum cleaners too. As shown in FIG. 2, the suction pipe 5 can be inserted into a corresponding provided on the vacuum cleaner housing. The remaining hose length then extends above the vacuum cleaner housing between the suction opening 2 and the upper end of the suction pipe 5. It is thus no additional space to the side of the vacuum cleaner to accommodate the suction hose 4 needed.
  • Hose end 6 of the suction hose 4 there is also the possibility of this hose end 6 slidably to arrange in the intake manifold 5. It must then be on both ends of the suction pipe 5 corresponding stops and seals are provided, through which the displacement of the suction hose 4 in the suction pipe 5 is limited. at Such an embodiment variant can therefore suction hose 4 from suction pipe 5 be pulled out. This results in a larger radius of action if the same Hose length is maintained. But it can also keep the same Radius of action shortened the hose length according to the length of the suction pipe 5 become. This then leads to the fact that after magazining the suction hose 4 an even shorter hose length remains in the suction pipe 5, which is the space-saving Stowage of the vacuum cleaner 1 further facilitated.
  • the suction hose 4 in one section as an automatically extending hose and in another To form part of the area as a self-shortening hose.
