Description

The The invention relates to a Staubsaugerbodendüse according to the preamble of Claim 1.

The various vacuum cleaner types according to the prior art can in principle be divided into two different types:
In so-called canister vacuum cleaners, the motor, blower, filter unit and electronic devices are arranged in a housing, which is usually mounted on rollers. An often telescopically adjustable in length suction pipe is connected at one end by means of a flexible suction hose to the housing or the blower of the vacuum cleaner and has at its other end to a floor nozzle, which comes into contact with the surface to be cleaned.

A second design form the so-called hand vacuum cleaner. In difference to the vacuum cleaners here the suction pipe is rigidly connected to the vacuum cleaner housing. Again, engine, blower, Electrics and filter unit housed in the housing. This points additionally on the opposite side of the intake manifold a in renewal handle mounted on the suction tube for handling.

through the floor nozzle will be that of engine and blower generated negative pressure applied to the surfaces to be cleaned. These are usually either hard, smooth surfaces of floor coverings like parquet, PVC, stone etc. or to textile surfaces like about carpets, Furniture upholstery, etc. Here, the different nature of the surface partially opposing Requirements for the functionality of the floor nozzle. at structured, air-permeable Surfaces, such as carpets, is usually a possible good contact with the floor nozzle he wishes, to achieve a deep and high suction effect. When smooth surfaces on the other hand, the direct suction is often insufficient to make it tight Dirt particles from the surface to solve. In addition, there is, depending on the structural design, the risk of a fixed suction the floor nozzle and thus possibly also the damage to the floor covering Scratch.

Floor nozzles according to the state The technique is therefore usually with one or more bristle strips fitted. These are arranged so that their bristles of the underside of the floor nozzle, which the surface to be cleaned contacted, extend substantially perpendicular to the floor nozzle. Usually These bristles are on a foot switch on the floor nozzle on a Mechanics between an extended position in which the bristles protrude from the bottom of the floor nozzle and so can contact the flooring and optionally one Distance between nozzle and flooring, as well as a recessed position, in the they are essentially retracted without function in the floor nozzle, switchable.

On In the extended state, this way becomes a brushing action on the surface to be cleaned surface exercised and segregated dirt detached from the floor covering, which can then be sucked. Optionally, by means of the bristle strip by the increased distance between floor nozzle and surface a sufficiently large side in the floor nozzle entering airflow allows and a tight eye of the floor nozzle or scratching the soil surface prevented. In the retracted Condition, however, is sufficient greater Negative pressure for the cleaning of textile surfaces to disposal. Depending on the design of the mechanism, the extension or Retraction of the bristle strip is provided, is the process of Switching under circumstances associated with a relatively high effort. In any case the process of cleaning the floor surface must be interrupted. This is especially common Change between different surfaces disturbing.

It An object of the present invention is to provide a vacuum cleaner floor nozzle, which at least the above-mentioned disadvantages of the prior art partially eliminated.

These The object is achieved by the features of the independent claims.

advantageous embodiments of the invention are in the dependent claims specified.

The invention builds on the generic Staubsaugerbodendüse characterized in that a change between the first and the second position takes place automatically, that an indication of the current position of the bristle strip is provided and that a surface of the display complements a surface of the housing. The display simultaneously shows the operator the current position of the bristle strip on the surface of the vacuum cleaner floor nozzle, allowing the operator to conveniently monitor the proper operation of the bristle bar. This is particularly useful in the case of an automatic change of position of the bristle strip, whereby an automatic moves the operator of the vacuum cleaner floor nozzle from one else necessary switching the bristle strip freed and thus allows a fluid and efficient workflow.

at a further embodiment The invention provides that the display is a viewing window in the case includes. This provides an easy-to-implement option In particular, for example, with the bristle strip connected mechanical elements within the housing the Staubsaugerbodendüse at a change of the position of the bristle bar these in the viewing window visualize.

at a preferred embodiment the invention is provided that the viewing window with one piece the housing accomplished is. In this way, a particularly sturdy and durable connection between viewing window and housing be achieved. Furthermore, so will the number of individual parts reduced.

at a likewise advantageous development of the invention is provided, that the viewing window is welded to the housing. In particular, the viewing window by means of a Ultraschallverschweißung the housing be molded so as to produce the one-piece look of the window and housing.

alternative can be provided in one embodiment be that the viewing window by means of a polishing operation on the casing will be produced. In particular, if the case and the viewing window off a material (eg a transparent polymer such as PC, PMMA, PP, etc.), the window can be at the appropriate place polished become. The remaining surface of the housing can then be structured, for example, to the housing and to make the viewing window from one part.

Of Furthermore, an advantageous embodiment results from the fact that the Viewing window is attached as a separate component to the housing. This can For example, by clipping, gluing, etc. happen, which one from the case separate production possible is.

Farther can be advantageously provided that the viewing window a magnification effect causes. By such a magnification or magnifying effect By means of a convex lens, the visibility from below the viewing window located display elements are increased.

Of Further may be provided in a preferred embodiment, that the display comprises a light source. Such bulbs can alternatively or additionally attached to the viewing window and optionally next to the position the bristle strip also represent more information.

Especially can be provided that the display to a vacuum signal responds. By means of a suitable vacuum sensor such a Signal are generated and brought to the bulb for display become.

Of the The invention is based on the finding that it is in an automatic Change the bristle strip of a vacuum cleaner floor nozzle between a retracted and an extended position makes sense, to indicate the current position of the bristle strip at the top of the vacuum cleaner floor nozzle. It is advantageous, the display window in one piece to the upper shell to mold. If the top shell of the nozzle, for example, from a made of transparent polymer, the window can be polished and the remaining area structured executed , whereby the upper shell and the viewing window form a single part. A display element can be connected directly to the bristle strip or over to move a separate lever. Alternatively, the ad one over output a signal generated by a vacuum sensor to a light source. The The present invention can be used with all common vacuum cleaner types.

The The invention will now be described with reference to the accompanying drawings illustrated by way of example with reference to a particularly preferred embodiment.

1 a perspective view of a Staubsaugerbodendüse invention in a first state; and

2 a perspective view of the invention Staubsaugerbodendüse in a second state.

1 shows a perspective view of a Staubsaugerbodendüse invention 10 , This has a housing 11 on, which is in an upper shell 12 and a housing lower part 13 divides. Furthermore, there are a suction pipe connection 15 and a bristle strip 14 intended. The upper shell 12 is made of a transparent polymer such as PC, PMMA or PP. In the upper shell 12 is the ad 16 integrated. This is in the otherwise structured surface of the upper shell 12 a viewing window 18 polished in. Alternatively to the production of the upper shell 12 and the ad 16 from a material can the viewing window 18 by means of an ultrasound welding process are integrated into the upper shell. Furthermore, it is also possible, the viewing window by means of a suitable holder in the upper shell 12 be clipped to provide. Below the viewing window 18 inside the case 11 there is a display element 20 , The display element 20 is about a mechanism, not shown, with the bristle strip 14 movably connected. The bristle strip 14 is automatically switched over by a suitable mechanism between an extended state and a retracted state. In the in 1 shown position, the bristle strip is shown in the extended state, 2 shows the Staubsaugerbodendüse 10 with retracted bristle strip 14 ,

In the in 1 illustrated extended state of the bristle strip 14 a suitable mechanism moves the display element 20 close to the viewing window 18 approach. In this way, one is on the display element 20 attached display, such as suitable symbols, visible, where appropriate, you can also on a suitable color design of the display element 20 restrict. In 2 is the vacuum cleaner floor nozzle 10 with the bristle strip 14 shown in the retracted state. In this case, the display element 20 from the viewing window 18 a greater distance and it is therefore not visible. In this way, the user can the func ontüchtigkeit the automatic switching of the bristle strip 14 conveniently over the display 16 follow.

The in the above description, in the drawings, and in the claims disclosed features of the invention can both individually and also in any combination for the realization of the invention be essential.
