"Drain hose with elbow, in particular for washing machines "

The purpose of the innovation is to have a drain hose in particular for washing machines that is particularly flexible and that has one bend to hang on Has wash basin or the like, the hose being interchangeably connected to the elbow. Of the The hose should still be resistant to treading, bending or kinking, so it should neither be stepped on nor change its free passage cross-section when bending. In addition, the hose should be of any length can be connected to the manifold without special tools

There are already known drain hoses in washing machines. They are mainly made of a thermoplastic Material made, mostly in such a way that an extruded hose with a thick wall is cut to a desired length cut off and the elbow is produced by bending and thermosetting. Elbow and straight length are

so from one piece. The disadvantages of such a hose "are that he as a result of large Wall thickness is not particularly flexible, its length is not changed afterwards without special coupling can be, as well as when falling below a certain bending radius due to the lack of a support spiral buckles and in the worst case the necessary free passage is closed, which leads to a disruption the washing process sequence can lead. The step resistance is due to the lack of a support spiral insufficient, which also leads to a reduction in cross-section and thus to the disruption of the washing process can lead.

The purpose of the invention is achieved in that in a Elbow made of plastic or metal, which has an internal thread at the end of its long leg, a well-known, flexible, step and bend-resistant with a support turn. provided, external thread-like trained hose is screwed.

According to a further feature of the invention, the free passage of the elbow is the same as the free passage of the connected hose.

The design according to the invention avoids the disadvantages of the known designs, because bends and hose consist of two parts.

In the drawing, the drain hose is according to the innovation shown. It means:

1 elbow made of plastic or metal with internal thread to accommodate the hose at the long leg end;

2 tube formers, preferably made of thermoplastic material;

3 support turns made of metal with thermoplastic coating.

The hose consists of an internal support coil (2) made of metal, which is protected against corrosion by a Plastic coating is protected. The plastic coating of the helical support is with the hose former firmly connected by welding or at the top, moreover the helical support lies positively in a bed that the hose former has on the inside. The necessary Flexibility is achieved by the fact that the hose has indentations due to its external helical formation having, wherein the wall thickness at the wave troughs is less than the wall thickness at the wave crests. The use of a helical support gives the hose its crush resistance and flexural strength.

By separating the manifold and tubing, both of which can be assembled as described above, it is possible to tubes of any length Mine special Yferkzeug · use

Claims (2)

P.Ä.62863i * -5.9.8i (claims 1. Drainage pipe, especially for washing machines, characterized in that in a manifold (1) made of plastic or metal, which at the end of its long Leg has an internal thread (2), a per se "known flexible, tread and bend-resistant with a Support helix (3) provided, externally thread-like hose is screwed. 2. Drainage hose according to claim 1, characterized in that that the free passage of the bend (1) is equal to the free passage of the connected Hose is.
