Definitions

  • the present invention relates to a flow variator for hair dryers according to the preamble of patent claim 1.
  • Pulsators for hair dryers serve to swirl the even air flow generated by the fan of the hair dryer and to convert it into a pulsating air flow that dries the hair faster.
  • Such a pulsator is known, for example, from DE-OS-32 25 944. It has a rotor which is mounted coaxially to the air outlet of the hair dryer and has one or more inclined vanes which can be detected by the air flow of the hair dryer fan and which is rotated by the air flow in such a way that a swirling of the exiting air flow is caused, which causes a pulsating flow to the air flow hair to be dried and thus faster drying.
  • This known pulsator has the disadvantage, among other things, that it does not offer the possibility of adjusting the pulse frequency and / or the pulse strength of the air stream flowing into the hair, as is necessary in order to achieve optimal hairdressing results using the latest hairdressing techniques.
  • the present invention is therefore based on the object of providing a flow variator of the type mentioned at the outset, which does not have the disadvantages of the known pulsators and which can be easily fitted onto a conventional hair dryer if required.
  • FIGS. 1 and 2 the described advantageous embodiment variant of a flow variator according to the invention is a substantially tubular device which comprises an outer ring 1 and an inner ring 2 with a rotor 3 arranged centrally therein.
  • the rotor 3 has on its front side, ie the air outlet side, a flat or slightly convex cover 6, which according to FIG. 2 has two spatula-like cutouts 7, 7 ', which are triangular in their outer areas and slit-shaped in their central areas .
  • the side of the rotor 3 opposite the air flow generated by the fan of the hair dryer advantageously has curved lamellae 8, as can be seen from FIG. 3.
  • the depth of these lamellae advantageously increases from the center of the rotor 3 towards its periphery, as can be clearly seen from FIGS. 4 and 5.
  • the latter is intended to receive a bearing mandrel 11 which can be inserted into a central bore 12 which is located in the center of three star-shaped webs 13, 13 'and 13' of the rotor housing 2.
  • the bearing sleeve 10 and the bearing mandrel 11 advantageously form a maintenance-free bearing, around which the rotor 2, driven by the air flow generated by the hair dryer fan, can be freely rotated.
  • the inner ring 2 has a substantially all-round groove 14 in its front area, which is only interrupted by webs, not shown in the drawing, which the front area 15 of the inner ring 2 with this connects.
  • this groove 14 is almost completely covered by the outer ring 1 in such a way that almost no air can pass through it.
  • the flow variator according to the invention is placed by means of the inner ring 2, must exit in this setting of the outer ring 1 through the two cutouts 7, 7 '.
  • the rotor 3 is set into only a slow rotation and a low-frequency, strongly pulsed air stream strikes the hair lying behind the flow variator in the direction of flow. This is the result of a strong air flow on the hair during each cut-out, whereas little or no air hits the hair between the cut-offs.
  • This low-frequency, strongly pulsed air flow causes a rhythmic movement of the hair, which is thereby dispersed so that the air can wash around it from all sides, which leads to very rapid drying.
  • the flow variator according to the invention enables air flows for drying the hair generate that can go from strongly pulsed to gentle and almost even.
  • the second advantageous embodiment variant of a flow variator according to the invention described here, as shown in FIG. 6, differs from the one described above in particular in that its actuation and the central mounting of the rotor are implemented somewhat differently.
  • this embodiment variant of a flow variator according to the invention at least one slot 24 in the outer ring 1 and correspondingly at least one pin 25 in the inner ring 2 are provided. They interact in the manner described above and serve for the axial displacement of the outer ring 1 relative to the inner ring 2, this displacement being caused by a relative rotation of the two rings 1 and 2.
  • a coupling ring 26 which can be placed on the outer ring 1 enables the flow variator to be easily assembled by pushing the outer ring 1 over the inner ring 2 in such a way that the pin 25 engages in the slot 24, whereupon to close the slot 24 of the coupling ring 26 from behind is pushed onto the outer ring 1 so that a second pin 27 provided thereon engages in the end region of the slot 24.
  • the coupling ring 26 and the outer ring 1 are connected to one another by means of known snap closures which are not shown in the drawing.
  • a rotor 3 is advantageously used, the fins 8 of which can be straight.
  • the use of a cover for the conical rotor base 9 is dispensed with.
  • the rotor base 9 can be designed centrally so that a bearing bush 30 into which a bearing pin 29 has previously been inserted can be pressed into it.
  • the two design variants of a flow variator according to the invention can be constructed differently in detail than is apparent from the foregoing and the drawing. Individual structural details of one embodiment variant can be combined with those of the other without any problems. It must be ensured that the possibility that peripheral ducts can be opened more or less must always exist in order to be able to produce the changes in the exiting air flow described above.
  • the rotor 3 and with it the fins 8 can be designed differently. It is also possible to provide only an axial displacement of these two components relative to one another instead of a possibility of rotating the outer ring 1 on the inner ring 2. Then the bearing of the rotor 3 in the inner ring 2 can be designed differently than described above, without thereby deviating from the inventive concept.
  • connection between the flow variator and the hair dryer can of course be adapted to the prevailing conditions, this being possible, for example, by means of a flexibly designed inner ring area.
  • the flow variator can also be designed directly as an integral part of the hair dryer, in which case it may be useful to place an inner ring instead of a sliding outer ring to make the hair dryer housing slidable.
  • all of these constructive modifications compared to the embodiment variants of the invention described above are within the scope of what a person skilled in the art can do without inventive step.
