Definitions
- a vacuum cleaner nozzle with the three described above Purpose is known from DE 690 03 698 T2.
- a brush strip is an element for cleaning smooth floors and a pull lip provided on a trained as a support plate holder are attached.
- the Brush strip is U-shaped in plan view and extends in the direction of the forward movement of the Suction head in front of the suction mouth and to the side of it.
- the flexible pull-off lip is arranged behind the suction mouth and only active when the suction head moves forward. at a backward movement will run over the wet. This is handling disadvantageous, especially in Household, it is common to have floors with back and forth Clean movements of the suction head.
- a vacuum cleaner nozzle which only suitable for cleaning wet smooth floors is.
- the suction head consists of an open bottom funnel-shaped housing, flexible on the lower edges Pull lips made of rubber or plastic are arranged. To the Cleaning dry surfaces, especially for that Dry vacuuming on carpets is the vacuum cleaner nozzle not suitable.
- a vacuum cleaner nozzle known from DE-A 38 01 757, the is optimized for dry vacuuming carpets behind the suction mouth there is an elastic bar or lip arranged. The effect of this lip is that Concentrate suction flow and the ineffective emergence To prevent secondary air.
- the well-known vacuum cleaner nozzle is not set up and it is unsuitable for wet vacuuming smooth floors.
- the invention has for its object a three-purpose vacuum cleaner nozzle with the purposes described at the beginning specify that movable with small pushing force has good dry suction properties on carpets and both forward and one Backward movement Effective wetness and dirt from smooth floors can record.
- the task is the triple-purpose vacuum cleaner nozzle construction described above according to the invention solved that the pull lip in the direction of the forward movement the suction head is arranged in front of the suction mouth that support rollers are arranged next to the pull-off lip, which at lowered holder stand up on the floor and together with the roller the bottom functional distance of the Determine the pull-off lip when vacuuming smooth floors, and that behind the suction mouth there is a flexible rubber wiper or Plastic is arranged.
- the support rollers as well as the Rollers, which together form support elements, are so set up that they the when vacuuming smooth floors Determine the functional distance of the pull lip. This is with Wet suction supported on the smooth floor to be cleaned.
- Support rollers and the roller are height-fixed on the suction head attached. Together they determine when vacuuming dry Carpets the functional gap at the bottom of the suction mouth edges and the thread lifter.
- the invention are the support rollers on the holder stored and retractable and extendable together with it. At the Dry vacuuming of carpets is the holder and with this retracted the pull lip, so that the suction head plate lies on the carpet to be cleaned and at a movement of the suction head slides on this.
- the rear scraper can be on the underside of the suction head be arranged fixed to the housing.
- vacuuming dry He helps carpets and smooth floors to concentrate of the suction air flow and prevents entry ineffective secondary air.
- wet sucking it fulfills the Function of a wiper, which when the Takes suction head with it and feeds it to the suction mouth area, where the moisture is sucked off.
- the one behind the suction mouth arranged flexible wipers thus fulfills one multiple function.
- the holder as a lifting and lowering support plate trained to which the rear scraper is connected is. It can be similar to the front pull-off lip be designed.
- the invention is based on the knowledge that the components more common, for dry vacuuming carpets and Smooth floors of vacuum cleaner nozzles set up easily and without increasing the manufacturing or assembly technology Effort also for wet vacuuming Smooth floors can be used if the known Vacuum cleaner nozzles usual retractable and extendable brush strips with rubber or plastic pull-off lips to be replaced in the extended state when dry vacuuming smooth floors function as a brush strip meet and are designed accordingly, and if continue the coordination of the support elements is set up that the functional distance when vacuuming carpets dry the suction mouth edges and the thread lifter from that Determine carpeting, and that when wet vacuuming Smooth floors determine the functional distance between the pull-off lips.
- the invention teaches that in Forward movement of the vacuum front puller lip the forward movement can be flexibly deflected or is arranged and a stiffener for the backward movement experiences.
- the scraper located behind the suction mouth expediently represents an inverse design Pull-off lip.
- the pull-off lip or the scraper can Have profiles that are in one direction Reduce the area moment of inertia so that the described flexible deflection takes place, and in the other direction of movement increase the area moment of inertia so that the stiffening described.
- the Pull lip a vertically ribbed outer surface and a smooth with a sharp bottom edge Inner surface on.
- the extended pull-off lip lies with the Forward movement of the suction head with the outer ribs on the to be cleaned smooth floor, whereby dirt as well as wetness of the voids remaining between the outer ribs are run over.
- the extended pull-off lip is flat on the smooth floor to be cleaned and forms one sharp wiping edge that takes away dirt and moisture.
- the rear scraper is suitably appropriate designed.
- the three-purpose vacuum cleaner nozzle 1 shown in the figures is for dry vacuuming on carpets, for that Dry vacuuming on smooth floors as well as for wet vacuuming Smooth floors set up and fulfills three purposes.
- Fig. 1 shows the functional positions Wet vacuuming on smooth floors and dry vacuuming on smooth floors, as explained in more detail below.
- 2 shows the functional position dry vacuuming on carpets.
- a suction head 2 initially belongs to the basic structure and a lower suction head plate 3, one to be cleaned Bottom open, channel-shaped suction mouth 4 and with suction mouth edges 5 and thread lifters 6 for dry vacuuming of carpets. You can also see on the support elements 7, 7 'supported on the floor to be cleaned. These consist of a roller 7, which on the in Forward movement rear end of the suction head 2 is arranged is, and from support rollers 7 'in the area next to a front pull lip 9 are arranged. In the embodiment are the support rollers 7 'and the roller 7 fixed in height to the suction head 2, the arrangement is set up so that the pull lip 9 in the extended Condition protrudes slightly on the underside and with less Redirection rests on the floor.
- FIGS. 1 and 2 show also a liftable and lowerable holder in the form of a Support plate 8 in the suction head 2, which is in the working direction the suction mouth 4, the flexible pull lip 9 made of rubber or Plastic and behind the suction mouth 4 a wiper 9 ', also in the form of a flexible rubber lip or has plastic.
- Pull-off lip and wiper 9, 9 ' are on and with the lifting and lowering of the support plate 8 extendable. This is done on a comparative basis 1 and 2 and in the area of the pull-off lip 9 registered double arrows 10 referenced.
- the floor to be cleaned is a smooth floor.
- FIG. 2 where the Pulling lips are retracted and the functional distance F was indicated by a double arrow. simultaneously determine the rollers and support rollers 7, 7 'in the embodiment the functional distance when vacuuming smooth floors F of the pull-off lip and the scraper 9, 9 ', for which purpose the Fig. 1 is referred.
- running and support rollers 7, 7 'in turn adjustable in height to set up in order to optimize in the area of Functions dry vacuuming on smooth floors on the one hand and To achieve wet vacuuming on smooth floors on the other hand.
- the front support rollers 7 on the Support plate 8 stored and together with this extendable.
- Fig. 1 was indicated that the support plate 8 with pull-off lip 9 and wiper 9 ' height adjustable via foot control.
- the front pull-off lip 9 can be moved in and out. It is attached to a holder 8 which by means of an angle lever 14 can be raised and lowered in the suction head 2 is arranged. Instead of an angle lever 14 can also other actuators, e.g. a slide arrangement, be provided.
- the rear scraper 9 ' is on the bottom of the suction head 2 arranged fixed to the housing.
