Definitions

  • the invention relates to a floor nozzle for vacuum cleaners, in particular an electric or turbo floor nozzle with a driven, roller-shaped cleaning device which is rotatably mounted in the suction chamber of the nozzle housing and in part extends through a slot arranged in the housing base.
  • the floor nozzle is subject to excessive wear and is significantly impaired in its performance.
  • Another disadvantage is that with repeated opening and closing of the floor plate, locking parts can be lost or the corresponding threaded devices in the housing can be damaged, so that after a relatively short period of use of the floor nozzle, the sealing of the suction chamber is no longer guaranteed and the performance of the floor nozzle drops.
  • the bottom cover must be made relatively stable since the brush roller bearings are inserted from below and are supported on the cover. This increases the weight of the floor nozzle. Since the underside of the floor nozzle is exposed to greater wear, the bottom cover is usually made of metal, while the floor nozzle is otherwise made of plastic. The use of separate metal parts leads to an increase in manufacturing costs. All in all, it can be said that the known floor nozzle is user-friendly and maintenance-unfriendly and, over a longer period of time, increasingly shows performance losses.
  • the invention is therefore based on the object of improving a floor nozzle of the generic type in such a way that the disadvantages mentioned above do not occur, i.e. that the floor nozzle is designed to be user-friendly and maintenance-friendly in a structurally simplified manner and should not have any performance losses over a longer period of use.
  • the nozzle housing has a substantially closed base and a closable part in its upper housing section Has opening through which the suction chamber and the mechanical drive parts of the cleaning device are accessible in the operating position of the floor nozzle.
  • This opening can be closed in an advantageous manner by a lid hinged to the nozzle housing, which can be opened by the user at any time in the feed direction of the nozzle housing, so that the suction chamber and the mechanical drive parts are accessible for cleaning or for minor maintenance work that can be carried out by the user himself .
  • the bearing blocks are made of a self-lubricating plastic and have two spring tongues arranged on the side, which are automatically compressed by side guides during installation and then snap into their correct position.
  • the bearing blocks are made of a self-lubricating plastic and have two spring tongues arranged on the side, which are automatically compressed by side guides during installation and then snap into their correct position.
  • the lid Since the lid only has to be opened upwards, the construction is user-friendly, so that the brush roller and the drive units can be checked at any time, for example after each suction operation, and any reduction in performance of the floor nozzle is avoided.
  • the manufacturing costs of the floor nozzle according to the invention are low, since the housing parts are made of plastic and the lid essentially only takes on the locking function and therefore does not have to be excessively stable.
  • the cover In the area of the cover section facing the pipe socket of the floor nozzle, the cover has a recess which interacts with a corresponding profile lug arranged on the pipe socket, whereby a locking device is formed for the pipe socket and the pipe in an over-center position is movable into a parking position.
  • the tube is in a stable position in this position so that it cannot fall over or fall back, and since it is fixed in the straight direction, there can also be no more rotary movement which could possibly cause the tube to tip over.
  • the lid also serves to control a motor switch by switching the switch in the closed position so that the floor nozzle is ready for operation, while the power supply to the switch is interrupted when the lid is opened, so that the brush roller comes to a temporary standstill in the open position the lid is guaranteed.
  • the lid is articulated via film hinges, which are spaced apart on the front housing end wall of the floor nozzle.
  • the floor nozzle designated 1 for vacuum cleaners has a nozzle housing 2 with a substantially closed bottom 3.
  • the nozzle housing is supported on the floor by means of wheels 4, 5, which are arranged symmetrically with respect to the longitudinal center line 6 (see FIG. 7).
  • a suction chamber 7 In the front area of the nozzle housing 2 there is a suction chamber 7, in which a brush roller 8 is rotatably mounted, at least the bristles 9 reaching through a slot 10 arranged in the housing base 3 in order to contact the bottom surface 11, e.g. a carpeted floor to come into contact with.
  • the edges 12, 13 of the housing which laterally delimit the slot 10 are reinforced by means of metal surrounds 14.
  • the brush roller 8 is inserted with the bearing and drive parts 15, not described in detail, such as bearing blocks, spring tongues as lateral guides, V-belts and the like from above through an opening in the suction space 7. This opening is closed by a cover 16, which covers essentially the entire housing of the floor nozzle.
  • the cover On the inside, the cover is stiffened by ribs 17, these ribs engaging in housing grooves 18 and sealing the suction space 7 to the outside.
  • the air flows in the direction of the arrows 19 through the slot 10 into the suction chamber 7 and passes through the channel 20 around the suction opening 21 of the rotating nozzle 22 and from there into the tilting nozzle 23 and not shown pipe to the vacuum cleaner.
  • the cover 16 has a recess 24 in the area facing the socket, which cooperates with a nose 25 attached to the socket 23 and forms a locking device with the latter.
  • a nose 25 is engaged in the recess 24 so that the nozzle with the adjoining tube is held in a parking position.
  • the cover 16 is articulated on the front housing end wall 26 by means of a film hinge 27, which is connected to at least one latching device (28), which in turn can be latched into a corresponding recess 29 in the front housing end wall 26.
  • the film hinge is screwed or glued to the inside of the cover 16 by means of a flat, plate-shaped flange 30.
  • the latching device has guide elements 31 on its front-facing end face, onto which corresponding guide elements of a butt profile 33 can be pushed.
  • the butt profile 33 essentially covers the gap between the cover and the housing end wall 26 with an upper profile nose.
  • FIG. 6 An alternative exemplary embodiment for fastening the cover 34 to the front housing end wall 35 is shown in FIG. 6, the film hinge 36 being an integral part of the butt profile 37.
  • the butt profile in turn has guide elements 38, 39 which can be inserted into corresponding counter-guide elements 40, 41 which are fastened to the cover 34 or to the front housing end wall 35.
