DE19802508A1 - Device for the detachable coupling of a suction hose connection of vacuum cleaners - Google Patents

Description

The invention relates to a device for releasable coupling of a suction hose connection from Vacuum cleaners via a in the vacuum cleaner housing arranged receiving element and one on the suction hose arranged in the receiving element, lockable nozzle, the suction hose on the the side facing away from the vacuum cleaner housing with attachments or floor nozzles is connected.

Such training with a detachable connection for a suction hose are known. There is Problem that for electrical attachments and Controls a separate connector is required. This makes it necessary Retrofits or conversions only individually  shape so that different connecting elements give a mixed picture.

The object of the invention is a simple one Training with the same elements for everyone To create needs that require the use of a enables uniform coupling element and convertible if necessary in the form of a modular system is.

This object is achieved according to the invention characterized in that parallel to the receiving element Vacuum cleaner housing an electrical outlet for one Control and / or operation of attachments is arranged and the usable nozzle one that Socket on the receiving element overlapping through an additional wall forms.

This makes it possible to have one for all needs uniform overall impression of the coupling area guarantee.

It is also provided that the through the wall formed recording room optionally with one with the Corresponding socket of the receiving element Plug can be equipped.

A simple training is that the area the wall to form the receiving space for the Socket as a detachable, clippable exchange element is trained and optionally integrated into the Socket insertable plug carries.

For easy assignment of the elements suggested that the receiving element and the neck  mutually associated guides for rotation-proof Show assignment.

A favorable embodiment is that the Edge zone of the expanded wall to form the Recording area an angular end area according to the housing wall of the vacuum cleaner having.

Further advantageous embodiments are the Characteristics of the further subclaims characterized.

In the drawing, an embodiment of the Invention shown schematically. Show it:

Fig. 1 shows a section through a device with a receiving element and nozzle used,

Fig. 2 is a representation of FIG. 1 rotated 90 degrees and

Fig. 3 is a top perspective view of a nozzle with an inserted connector on the interchangeable wall part.

In the arrangement shown, the area of the coupling is essentially shown. In this case, a tubular receiving element 2 is fixed in the partially shown housing wall 1 of the vacuum cleaner, which is continued by a bend 3 and leads to the filter bag. A socket 4 is arranged parallel to the receiving element 2 and is multipolar according to the requirements and thus has all supply and control line connections.

To form a suction hose connection, a connection piece 5 connected to the suction hose is arranged, which can be fixed in a known manner in the inserted state via a corresponding locking arrangement 10 . In this case, the socket 5 has a cup-shaped additional wall 6 , which forms a receiving space 7 which overlaps the socket 4 on the receiving element 2 .

The wall 6 has an exchangeable wall part 8 in the area of the socket 4 as an exchange element, which is accordingly equipped with a plug 9 and an electrical connection element and can be inserted and clipped into the wall 6 . This makes it possible to use an exchangeable wall part 8 with and without electrical equipment with the same arrangement, so that retrofitting according to requirements is also possible.

Such a socket 5 with an integrated plug 9 can thus be inserted mechanically when it is inserted with the corresponding socket 4 and the receiving element 2 as an electrical connection.
