  • a manageable free end area of the hose line is as a spray head with a large number of supply openings or Spray nozzles formed; by inserting this spray head into the interior of a hot air steamer, it can be sprayed and cleaned well.
  • the previously known device takes up a comparatively large amount of space and has a large installation height, in particular in the case of a long rollable hose line.
  • the device has at least one deflecting roller or similar deflecting body, around which the hose line is guided in a U-shaped or loop-like manner, and that at least one deflecting body is held so movably against a restoring force that the portion of the hose line deflected around it can be brought from a shortened deflecting position into an at least approximate extended position while simultaneously changing the position of the deflecting body.
  • the device according to the invention thus has at least one deflecting roller or similar deflecting body, around which the hose line is guided loosely and approximately in a U or loop shape.
  • the sections of the hose line leading to this deflection roller and departing from it can thus be stored in a shortened deflection position which, for example, only has to be half as long as the total length of these two sections.
  • a tensile load acting on the portion of the hose line leading away from the deflection roller moves at least one deflection roller against a restoring force such that the hose line moves in this area from the shortened deflection approach your extended position.
  • a comparatively long section of the hose line can thus be provided in the device and removed from it.
  • the device according to the invention thus acts practically as an automatic hose reel, which releases the manageable free end area of the hose line when required and, after use, catches up or takes up again in a space-saving manner by means of its restoring force.
  • the hose line is not wound on a roll or drum, but can be arranged in a loop in one plane, the drum according to the invention can be designed flat in such a way that it is installed, for example, in the usual Gastronorm substructures or in a combi steamer can be integrated.
  • the device according to the invention can be used advantageously, particularly because of its flat, space-saving design, beyond the canteen area, for example if the hose line in the workshop area serves as an air line that can be gripped if required or as a flexible oil line.
  • the device according to the invention can, for example, be mounted on a lathe in industry in order to spray metal parts with oil by means of its hose line or to clean machines of any kind with compressed air.

  • a particularly advantageous embodiment according to the invention provides that the device has three deflecting rollers or similar deflecting bodies, of which a middle deflecting body is immovably held in the device and of which two outer deflecting rollers can be moved against a restoring force approximately in the direction of the middle deflecting body.
  • the hose line approaches its extended position when the two outer deflecting bodies are located in the area of the middle deflecting body.
  • an advantageous embodiment according to the invention provides that the deflection bodies, which are preferably designed as guide rollers, are each rotatably mounted in a deflection body cooler and that the deflection body holders of the position-changeable ones Deflection bodies are each movably held on a steel band or the like windable tension element, to which a reeling device is assigned, for example with a spring assembly.

  • the two pivot levers 43 and 44 are arranged in the end regions carrying the deflecting rollers 4, 6 in mutually offset pivot planes. As a result, these rollers 4 and 6 run past one another when the hose line 3 is pulled out and the levers 43 and 44 are pivoted, so that it is also possible to use comparatively long pivoting levers without having to change the size of the device housing 2. Despite the large "winding length", compact housings can be used. In the exemplary embodiment according to FIGS. 6 and 7, all three rollers 4, 5, 6 are mounted on pivotable levers. If necessary, it would also be enough if only two Pivot levers on opposite longitudinal sides of the device housing 2 - pivot levers 43, 44 - are provided.
