Vacuum cleaner assembly

description

The present invention vacuum cleaner assembly, in particular floor nozzle, comprising at least one suction device with at least one at least partially hollow base body with at least one first end with at least one suction nozzle, in particular for connection to at least one suction pipe and / or suction hose of a vacuum cleaner. The present invention also relates to a vacuum cleaner with such a vacuum cleaner assembly.

There are many known floor nozzles for vacuum cleaners. These floor nozzles function mostly satisfactorily and reliably. So are depending on the application

different floor nozzles can be used. For example, floor nozzles with sliding surfaces are used for carpets. Floor nozzles with brushes are used to vacuum hard floors such as tiles, wooden floors or laminate. Floor nozzles are also known in which a brush can be switched on so that such a floor nozzle can be flexibly adjusted according to the surface to be vacuumed.

The disadvantage of conventional floor nozzles is that they usually have a fixed basic shape and that you have to clear the floor to be vacuumed as much as possible in order not to be constantly disturbed by obstacles. Most will fit

Floor nozzles between chair legs or it is very difficult to maneuver between them.

Free spaces or gaps between pieces of furniture also usually have such a size or width that a conventional floor nozzle cannot be moved into the gap.

There are floor nozzles with swiveling or telescopic

Attachments have become known, which should bring about an improvement here. For example, US Pat. No. 3,608,126 A, US Pat. No. 6,536,076 B2, DE 4 413 071 A1, FR 2 076 110 A1 and AT 413789 B show such known floor nozzles. This

However, floor nozzles are sometimes very complex, not user-friendly and / or are often relatively large overall and can therefore not enter smaller gaps despite the movable attachment parts.

It is therefore the object of the present invention to provide an alternative floor nozzle which the above

mentioned disadvantages at least partially improved.

This object is achieved by a vacuum cleaner assembly with the features of claim 1 and by a vacuum cleaner with the features of claim 27. Preferred further developments and refinements of the invention emerge from

general description and description of the

Embodiments.

The vacuum cleaner assembly according to the invention comprises at least one suction device with at least one at least

sectionally hollow base body with at least one first end with at least one suction nozzle, which is used in particular to connect to at least one suction pipe and / or a suction hose of a vacuum cleaner.

According to the invention, the base body divides at a second end into at least two essentially tubular suction channels, each with at least one suction opening. At least one suction arm is in each case of the at least two suction openings assigned, wherein at least one suction arm is provided pivotably about the associated suction channel.

The vacuum cleaner assembly according to the invention is in particular as a floor nozzle for a vacuum cleaner or for any type of

Suction machine trained. The inventive

Vacuum cleaner assembly can be used, for example, on a conventional house vacuum cleaner. The possible use is not limited to such a vacuum cleaner, but can also be used with industrial vacuum cleaners, wet vacuum cleaners, wet and dry vacuum cleaners, dry vacuum cleaners and / or others

Vacuum cleaner-like apparatus can be used.

The at least one suction arm and in particular both suction arms can each be rotated or rotated about the associated suction channel.

pivotable provided. It is particularly preferred that the suction arms, when they stand on the floor in the position of use, are in particular pivotable forwards and / or backwards. Pivoting in an essentially horizontal direction, that is to say over the floor, is particularly preferred.

According to the application, the fact that the suction arms are pivotable or rotatable about a suction channel means in particular that the suction arms can be rotated around the suction channels or are rotated together with the suction channels.

In configurations in which, for example, the suction channels are assigned to the base body, the suction arms then preferably being fixedly or non-rotatably connected to the base body and / or manufactured in one piece with it, the suction arms are preferably rotatable or pivotable on the

Intake channels added. Then the suction channel is fixed and the suction arms rotate around the suction channel. In configurations in which the intake channels z. B. the

Are assigned suction arms, for example, if they are made in one piece with the suction arms and / or are not rotatably connected thereto, the suction arms are preferably via the

Suction channels received rotatably on the base body, so that the suction arms and the suction channels are rotated together. Suitable storage or reception of the is then preferred

Intake channels provided on the base body.

The base body or the suction device is designed in particular to be small or as narrow as possible. It is particularly preferred that the base body is not, or not significantly, wider than the suction nozzle, so that the entire width is not designed to be significantly wider than a conventional suction pipe of a vacuum cleaner. This makes it possible that by pivoting or even almost

complete folding by up to 90 ° or even more an extremely narrow vacuum cleaner assembly can be made available. So the vacuum cleaner assembly can depending on

Application can also be run into very narrow gaps.

The base body is preferably essentially of the

The basic shape is trapezoidal or embodied in the manner of a truncated pyramid, the intake ducts then being able to emerge on the base side of the truncated pyramid. With such a

Embodiment, a particularly suitable air flow with little noise emission is achieved.

The intake channels are preferably substantially in line with the intake port or with the opening of the

Intake formed. The pivot or rotation axis for the suction arms is preferably substantially at least

in sections through the suction opening or through the

Intake duct. In order to achieve sufficient stability of the rotatably designed suction arm, the suction channels are designed in particular to be essentially rigid and in particular completely rigid or stable, so that they offer a sufficiently stable hold for the suction arms, especially when the suction arms are received directly on the suction channels.

The intake ducts preferably have a rounded or round outer contour, at least in sections.

The intake ducts are available while the

Vacuum cleaner assembly preferably essentially perpendicular to the floor, so that the suction arms received thereon protrude to the left and right essentially transversely thereto.

In particular, at least two or exactly two suction channels are provided so that a suction arm can be provided on both sides to the left and right. However, more than two, for example three, intake ducts can also be provided, which are preferably arranged in a row. Then the two outer suction channels can be used to accommodate the suction arms

The vacuum cleaner assembly of the invention offers many

Advantages. A considerable advantage is that a particularly advantageous floor nozzle for vacuum cleaners is provided by the special design of the suction device with the at least two suction channels and the suction arms arranged or assigned to them.

On the one hand, it is achieved that the suction arms are pivotable

are designed. This can be achieved in particular when the suction arms are pivotable in both directions that when Vacuum the floor nozzle, for example, can move into a narrow gap.

To do this, the suction arms swivel away in a corresponding direction. In particular, it is also possible for a narrow gap to be crossed as an obstacle, with the suction arms being able to spread out again after crossing the obstacle. For this purpose, the suction arms are swiveled away in one direction when entering the obstacle. After crossing the obstacle, the suction arms can return to their home position

move back. When pulling the floor nozzle out of the

The suction arms swivel back in the opposite direction so that the floor nozzle can simply be moved out of the obstacle again.

In addition, the special arrangement and design of the suction device provides a very compact yet stable vacuum cleaner assembly, so that when the suction arms are folded in or pivoted in, they can also be retracted into particularly narrow gaps, so that the vacuum cleaner floor nozzle can be used in a particularly versatile manner.

At least one suction arm is preferred on at least one

In particular, the rubbers are then provided freely accessible so that they can be exchanged quickly and easily by a user in the event of a defect or a planned change.

In appropriate further training is the

Preloading device added to the base body and at least one suction arm. In particular, the attachment of at least one tension spring to the base body and a suction arm can be advantageous. In particular, it is expedient to attach one or two tension springs to the top of the suction arm, with the other side of the tension spring then
