Description

The invention relates to a suction nozzle for a vacuum cleaner, which can be connected to a handle tube or to a suction pipe of the vacuum cleaner.

The standard equipment of the vacuum cleaners on the market today usually includes a floor nozzle, a crevice nozzle and a upholstery nozzle as standard. Furthermore, the manufacturers also offer additional special nozzles with which you can supplement the suction tools for the vacuum cleaner. Nevertheless, so far for sucking problematic or hard to reach areas matching suction nozzles are missing, with which the resulting suction work can be done satisfactorily. In addition, the previously known special nozzles are tuned only for the device of the respective manufacturer and can not be used across manufacturers.

For example, sucking in a staircase is very problematic because often the conventional suction hoses and suction pipes are too short to reach each area of the staircase. In addition, can not be done in every corner of a house a thorough cleaning with the previously known suction nozzles, since the suction nozzles not only cover all parts of the surface to be sucked because of their shape can. In addition, with the hitherto known suction tools also sucking on and under furniture parts difficult, especially if, for example, in the apartment high cabinets are present or they are on relatively low furniture feet.

The invention thus raises the problem of providing a suction nozzle for use in a conventional vacuum cleaner, with which the disadvantages of the prior art known to be avoided and can be performed satisfactorily with the certain suction even in difficult problem areas.

The solution to this problem is solved by a suction nozzle with the features of claim 1. Advantageous embodiments and embodiments of the invention will become apparent from the following subclaims.

The inventively proposed suction nozzle is advantageously independent of manufacturer used in conjunction with a conventional vacuum cleaner. In this case, this suction nozzle is designed such that it can be easily attached to the handle tube or the suction pipe of the vacuum cleaner, without having to provide a complex Aufsteckmechanismus in the connection area.

Furthermore, can be achieved by the newly designed suction nozzle quite a number of advantages over the prior art. These advantages result primarily from the fact that a tubular nozzle body is used as the core component of the suction nozzle, which consists of a flexible plastic material. In this case, preferably a material is used, which can be produced for example by extrusion in a known manner from a thermoplastic material. This opens up the possibility to use for the nozzle body a generally used from the heating construction for the pipe insulation plastic material, which has been produced for a long time in a large scale as a yard goods simple and inexpensive. In addition, no significant tooling costs are incurred since the machine-technical infrastructure of the manufacturer operating on the market can be used. In the selection of the plastic material is preferably made of polyethylene (PE), said material is known to be flexible and behaves elastically and in its tubular structure but still has a sufficient rigidity.

In any case, it has surprisingly been found that a novel suction nozzle with previously unknown advantageous properties can be made available. It must be realized in the starting material only relatively small structural measures in order to develop a versatile usable suction nozzle.

In a first embodiment of the invention, a suction nozzle is provided, in which the nozzle body can be made of tubular portions of the plastic material in any length.

Here, the one open end of the nozzle body is provided as a connection area for attachment to the suction or handle tube of a vacuum cleaner, wherein suitably the input area of the plug-in opening is formed with a Aufsteckstruktur through which the handling is facilitated when plugging. In a preferred embodiment, it is provided to form a run-in slope in the entrance area. However, it is also possible to use additional connection techniques known from the prior art in this connection region, in which case a hose must be connected tightly and, as far as possible secured against rotation, to a pipe connection part. In addition, provision can be made in the connection area of the nozzle body, by which the extensibility is increased, thereby making it easier to attach the suction nozzle to the respective connection pipe of the vacuum cleaner or thereby increasing the tolerance range of the cooperating pipe diameter. Incidentally, the plastic material used is elastic enough so that it can be plugged on currently available suction or handle tubes offered on the market vacuum cleaner.

In a preferred embodiment, the opening at the other end of the nozzle body is used as a central suction opening, so that the suction air flow generated by the vacuum cleaner can be introduced axially into the nozzle body and guided over the main air channel formed by the cavity of the nozzle body to the filter devices of the device.

Furthermore, the open end of the nozzle body with the central suction opening can be formed as an obliquely inclined suction surface, so that thereby at the entrance of the suction nozzle quasi forms a nozzle structure with which can be sucked effectively especially in corners and cracks.

In a further development of the invention, the front region of the nozzle body can be formed with a special design of the nozzle tip, wherein in the region of the nozzle tip further suction openings are arranged, via which the suction air flow is directed radially into the main air channel. In an advantageous embodiment, the area of the nozzle tip is conically shaped with the arrangement of the suction openings, whereby suction work in certain problem areas can also be carried out with good results.

In the same way, a design form is conceivable in which at least one bevelled surface is provided in the outer region of the nozzle tip and the suction openings are positioned on this inclined surface. In a particularly advantageous embodiment, two or three inclined surfaces are formed in the region of the nozzle tip, on which the suction openings can be placed. As a result, in particular corner areas can suck effectively.

In a further advantageous embodiment, the nozzle body is provided on its tubular outer surface with a plurality of suction openings arranged one behind the other in the suction direction, via which a suction air flow can be conducted radially into the main air channel. The suction openings can be placed on a straight axial line, but it can also be several suction openings next to each other and / or positioned one behind the other.

In a preferred embodiment, leading into the surface of the nozzle body leading to the suction air ducts are formed, whereby the Sucking of the suction nozzle is avoided. In this case, for this purpose leading to the suction air ducts can be arranged both axially on the outer surface of the nozzle body and transverse to its axial axis. Furthermore, star-shaped aligned air ducts on the front end of the Nozzle body are provided to the suction port for the axial introduction of the suction air into the main air passage.

An inventively designed suction nozzle consists in an advantageous embodiment of the nozzle body with the suction openings and a connection part, or from the connection area in which no suction openings are provided. In this respect, as long as desired suction nozzles can be offered, either by correspondingly long connecting parts or extension parts, which are connected to each other via connecting elements.

Thus, for example, a nozzle body having the suction openings can be extended in a simple manner by a portion of the tubular plastic material is connected via a rectilinearly aligned connecting part with the actual nozzle body. Thus, the range of the suction nozzle can be extended almost arbitrarily.

In a further advantageous embodiment, the suction nozzle may be formed in the manner of a conventional floor nozzle. In this case, for example, a nozzle body designed according to the invention can connect in one-piece or two-part form to a connection part in an angularly aligned design form. In an advantageous, two-part embodiment is also provided to connect the nozzle body via an angle connector with the connection part.

In an advantageous development, the nozzle body and the connection part are each provided with a coordinated connection structure, so that the connection part and the nozzle body can be connected to one another for two different handling positions. In this case, the connection structures that correspond with one another in their fit are designed such that in a connection constellation, as with a conventional floor nozzle, suction can be carried out on the floor, while in the other connection position an overhead surface can be sucked. Thus, for example, the suction nozzle can be attached to the suction pipe of a vacuum cleaner such that standing down a high-lying surface of a cabinet in a comfortable manner is accessible, wherein the nozzle body is positioned in a position with downward suction openings on the connection part.

Overall, the invention achieves the advantage that by handling and using the inventively designed suction nozzles some hard to reach places can be edited and that the suction can be easily adapted with targeted selection of Saugdüsenart to difficult problem areas. In addition, the suction nozzle is very light in weight, thereby generating a low sliding resistance and also slides easily due to the plastic material used on the surfaces to be sucked. Furthermore, the suction nozzle behaves very gently in the suction operation and is therefore particularly well suited for vacuuming dust on smooth and delicate surfaces.

In the FIG. 1 In a simplified form, a vacuum cleaner 1 in the form of a vacuum cleaner of conventional design with a standard standard equipment according to the well-known prior art is shown symbolically. In this drawing, the parts involved in the suction operation, such as the flexible suction hose 2, the handle tube 3, the suction pipe 4 and a well-known floor nozzle 5 are shown. With reference to the arrows A and B shown in this overview drawing, it should be clarified at which point the suction nozzles 6 described in more detail below can be plugged for various suction work either on the connecting piece 31 of the handle tube 3 or on the connecting piece 41 of the suction tube.

The FIG. 2 shows in a first schematic representation of the individual parts of an inventively designed suction nozzle 6 with the indicated suction pipe 4 of a vacuum cleaner 1, while in the illustration in FIG. 3 the suction nozzle 6 is attached to the connecting piece 41 of the suction pipe 4. The suction nozzle 6 has a tubular construction and is made according to the invention of a flexible, thermoplastic plastic material, preferably made of polyethylene (PE). It can be used as a plastic material from the heating for the pipe insulation pertinent known material, which usually, for example, from an extruded foam material and a certain flexibility but still has a certain dimensional stability.

The in the FIGS. 2 and 3 illustrated embodiment of a suction nozzle 6 comprises an elongated tubular nozzle body 60, wherein at one end of the connection portion 61 is formed with a Aufsteckstruktur for attachment to a suction or handle tube.

In the front region of the nozzle body 60, a tapered, tapered nozzle tip 63 is integrally formed on the circumference of a plurality of suction ports 62 are arranged, via which the suction air flow is directed radially into the main air channel 60.1.

In the FIG. 3 shows the flexibility and expansibility of the selected suction nozzle material, in which the connection portion 61 of the tubular nozzle body 60 when spreading on the suction pipe 4 expand and thus can make a tight connection to the suction pipe 4.

In the FIG. 4 are shown in fragmentary perspective three suction nozzles 6 with differently shaped nozzle tips 63. It is in FIG. 4a ) already in the FIGS. 2 and 3 shown suction nozzle 6 shown. In addition, in this drawing, the formation of the connection portion 61 of the suction nozzle 6 is additionally shown, and that is the annular input portion of the nozzle body 60 circumferentially formed with a run-on slope 61.1, whereby the insertion of the suction tube 4 is facilitated in the suction nozzle 6.

In the FIG. 4b ) is formed on the nozzle tip 63 an obliquely tapering, flattened surface in which the suction openings 62 are placed. In the Figure 4c ) is a nozzle tip 63 can be seen, in which a total of three bevelled surfaces are provided in the region of the tip, on which the suction openings 62 are provided.

In the FIGS. 5 and 6 is shown in schematic form an embodiment of a suction nozzle 6, wherein the nozzle body 60 on its tubular outer surface a plurality, in the suction direction (arrow S) one behind the other Suction openings 62, via which the suction air flow is passed radially into the main air channel 60.1. In addition, suction air is directed axially into the nozzle body via the frontally arranged suction opening 60.2.

Furthermore, the leading to the suction ports 62 Luftleitkanäle are illustrated in these drawings. In this case 60 Luftleitkanäle 64 are formed on the outside of the nozzle body, which lead axially aligned to the suction ports 62, while the also molded and leading to the suction ports 62 Luftleitkanäle 65 are aligned transversely to the axial direction of the nozzle body 60. As with the in FIG. 6 can be seen, are also provided in the front end face of the nozzle body 60 also Luftleitkanäle 66 which lead to the suction opening 60.2. The arrangement of the air ducts 64, 65, 66 is formed so that a sufficient secondary air flow in the direction of the suction openings 60.2, 62 can form in the suction operation, so that thus the suction of the suction nozzle 6 is prevented at the respective working surface.

At the in FIGS. 5 and 6 illustrated embodiment, the air duct 64 is axially aligned and mounted on a line on the nozzle body 60 so that it is connected to the successively placed thereon suction openings 62 and also with the frontal nozzle opening 62.1. On the front side also Luftleitkanäle 66 are provided which are directed radially to the frontal suction port 62.1. Furthermore, 60 air guide channels 65 are formed on the nozzle body, which also lead to the suction openings 62 and are aligned transversely to the axial line of the nozzle body.

The FIGS. 7 to 11 illustrate in further views of the above arrangement and placement of the air ducts 64, 65, 66 and the suction openings 62, 60.2 on the nozzle body 60 in a different representation.

In the FIGS. 7 and 8 the front part of the nozzle body 60 is shown, wherein the FIG. 8 the end face of the nozzle body 60 according to the in FIG. 7 represented by the arrow C direction indicated.

In FIG. 9 is the portion of a nozzle body 60 in a side view with the two sectional lines A - A and B - B shown. Accordingly, the shows FIG. 10 the nozzle body 60 at the section line A - A, at one point through the molded air duct 64 runs while in FIG. 11 the representation of the section line B - B is clarified, which passes through the intersection of the air duct 64 with the air duct 65 and the suction port 62.

The FIGS. 12 a) and b) and FIGS. 13 a) and b) each show in a side view suction nozzles 6, the nozzle body 60 have different lengths. Furthermore, in these drawings, the nozzle bodies are formed with differently shaped connecting structures 67, 68, whereby the suction nozzles 6 with the in the FIGS. 14 and 15 shown connecting parts 7, 8 can be connected. For this purpose, the connection parts 7, 8 also have on one side correspondingly shaped connection structures 67,. 68, whereby they can be positively connected to the respective nozzle body 60, while on the other side of the connecting parts 7, 8, a connection portion 61 is formed with a Aufsteckstruktur for attachment to a suction pipe 4 or handle tube 3 of a vacuum cleaner. Due to this embodiment of the items, the suction nozzles 6 with the connection parts 7, 8 to a in the FIGS. 16 and 17 assembled embodiment are shown. This allows the actively sucking nozzle body 60 in a simple manner for in the FIGS. 21, 22 and 23 symbolically sketched suction work to be aligned.

In the FIG. 16 illustrated embodiment illustrates the connection region (V) between a nozzle body 60 with in the FIGS. 12 a) and b) formed connecting structures 67 and the connecting part 7, while the FIG. 17 the connection region (V) between a nozzle body 60 with in the FIGS. 13 a) and b) illustrated connecting structure 68 and the connecting part 8 embodied.

The connection parts 7, 8 are each provided on one side with a connection region 61 for connection to the connection piece 41 of a suction tube 4 and on the other side with a connection region 67 (FIG. FIG. 14 ) or 68 ( FIG. 15 ) educated. The connecting regions 67, 68 formed on the connecting parts 7, 8 are configured in their shape such that they correspond to the connecting regions 67, 68 of the corresponding ones in the FIGS. 12 and 13 Suction nozzles 6 shown fit together fit.

The in the outline sketch of FIG. 16 illustrated connection area (V) is in the connection of a in FIG. 12a ) and b) shown nozzle body 60 with the connection part 7 in FIG. 14 formed by mitred beveled surfaces. In contrast, comes in FIG. 17 shown connection area by the connection of a nozzle body 60 according to the FIGS. 13a ) and b) with the connection part 8 in FIG. 15 conditions. As can be seen in the drawings, the two parts can be joined together by means of an angle connector 10. For the practicability of such a designed suction nozzle formed between the nozzle body 60 and the connecting part 7, 8 angle is important. This angle formed between the nozzle body 60 and the connecting part 7, 8 can be made more or less arbitrary depending on the application.

For sucking on the surface of a cabinet (see FIG. 21 ), an angle in a selection range between 100 ° and 130 ° has proved to be advantageous for many applications. For sucking with a suction nozzle 6 on a high-ceilinged cabinet surface, this angle is preferably 110 °.

With a suction nozzle 6, with a longer nozzle body 60 according to the FIGS. 12a) and 13a ), the otherwise often very difficult to access, high-lying surfaces of a cabinet 11 can be sucked in an advantageous manner, as the FIG. 21 illustrated. For this application, nozzle body 60 can be offered, which are adapted to common cabinet depths to be able to effectively and thoroughly vacuum a cabinet top.

If, for example, by sucking on a high-ceilinged cabinet ( FIG. 21 ) on sucking on the floor below a cabinet 12 ( FIG. 22 ), the longer nozzle body 60 (FIG. FIG. 12a ) are repositioned once with its connection ends, while in the interaction of the connecting structures 68, the parts are only once to rotate axially.

The short nozzle body 60 ( Figures 12b and 13b ) is in itself only for sucking on the floor or below a cabinet 11 in the foot panel area ( FIG. 23 ) thought.

In the FIG. 19 is still a rectilinear trained connecting part 10 is shown, which can serve to produce an extension of the range or to be used as an adapter to accommodate different diameters of the connected suction nozzles or connecting parts. An implied in this drawing rotation 91 is intended to prevent accidental rotation of the two parts in the assembled state.

Regardless, the suction nozzle 6 and the connecting part 7, 8 can also be made in one piece without a connection point, so that then the angle connector 10 can be omitted.

In the purely schematic diagrams of the FIGS. 20, 21, 22 and 23 are practice-relevant applications represented in symbolic form, these drawings illustrate the practical use of an inventively designed suction nozzle in four different applications.

The FIG. 20 shows the application of a suction nozzle 6 in one of the embodiments according to the FIGS. 2, 3 or 4 if, for example, a long range is required to be able to do the suction work. These can be high ceilings 12 or high corners, as is the case for example in a stairwell.

In FIG. 21 is the application of a suction nozzle 6 shown on a high surface or Saugebene. This may be, for example, the top of a cabinet 11. In contrast, the shows FIG. 22 the use of the same suction nozzle 6 for sucking under a cabinet 11, wherein the suction nozzle 6 was rotated with its active suction only by 180 °. However, this requires the two-part insert with a connection part 7 or 8.

Finally, the FIG. 23 nor the application, when a rather short suction nozzle 6 is used, for example, for sucking below a cabinet base is used. Such a short suction nozzle 6 with a length of, for example, 35 cm can also be used like a conventional floor nozzle, which is particularly suitable for hard floors.

The suction nozzle 6 itself can be offered in many different lengths due to the inventively provided shape of the nozzle body and the choice of materials, since the starting material is manufactured by the meter and only the cutting must be made in the predetermined length dimensions. In general, it is advisable to provide at least one suction nozzle 6 with a total length of 55 to 70 cm - preferably 65 cm - and a suction nozzle 6 with 30 to 40 cm - preferably 35 cm - to be able to do most of the daily arising suction work ,

The FIGS. 24 and 25 show an alternative embodiment of the nozzle body 60 of a suction nozzle according to the invention with two shell side axially parallel extending and spaced apart air ducts 64, which are each associated with offset radial suction openings 62. By providing the two axial air ducts, a fixed suction of the nozzle body 60 can be avoided on the object to be cleaned or the nozzle body 60 can be solved by rolling in a simple manner.

A modified embodiment of the angle connector 10 is shown in FIG FIG. 26 shown. The angle connector 10 sees a first connecting piece 10.1 for the nozzle body of the suction pipe and a second connecting piece 10.2. for the connection part. In each case, 10.3, 10.4 radially encircling collar 10.3, 10.4 are formed as an attachment for the nozzle body or the connection part to the connecting piece. Moreover, in the area of the connecting piece 10.1, 10.2 an anti-rotation 10.5 realized.

FIG. 27 shows an angular portion of a suction nozzle according to the invention with an angle connector 10, the nozzle body 60, the connecting part 7 and an angle cap 13 which is attached between the nozzle body 60 and the connecting part 7 to the angle connector 10.

Irrespective of this, there are no limits to the professional creativity in the vacuum cleaner field in order to provide obvious nozzle shapes and design variants adapted to the respective intended use with regard to the arrangement of the suction openings and the air ducts leading therethrough.
