Definitions

  • the present invention relates to a frequency-changeable pulsator for arrangement in the air inlet area of a hair dryer according to the preamble of patent claim 1.
  • Pulsators for hair dryers are used to convert the uniform air flow generated by the blower of the hair dryer into a pulsating air flow drying the hair faster.
  • Such a pulsator for the air outlet duct of a hair dryer is known from DE-OS-32 25 944, for example, which pulsates and swirls the escaping air flow. 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 has to be plugged onto the air outlet duct of the hair dryer and then unnecessarily lengthens it afterwards to the heating spirals, which can adversely affect the manageability of the hair dryer.
  • due to the high speed of its rotor it leads to a very high pulse frequency of the escaping air flow.
  • the use of hairdressing additives after the pulsator such as, for example, an undulating nozzle, leads to a neutralization of the pulsation, which limits the possible uses of this pulsator for the hairdresser.
  • This well-known pulsator itself in the hot air area is also conditionally unnecessarily expensive to store.
  • the present invention has for its object to provide a frequency-variable pulsator which does not have these and other disadvantages of known pulsators and which is suitable for arrangement in the air inlet area of a hair dryer and which also generates a pulsating air flow when using hairdressing additives at the air outlet of the hair dryer. According to the invention, this object is achieved by means of a pulsator as defined in claim 1.
  • the frequency-changeable pulsator according to the invention is designed in such a way that it instead of a conventional rear hairdryer cover on the Housing of a commercial hair dryer not shown in the drawing can be placed.
  • Cams 2 formed on the pulsator housing 1 can serve this purpose.
  • a housing base 5 with cut-out sectors 6 extends over the pulsator housing 1.
  • the center 7 of the housing base 5 is designed such that on the one hand it receives an axis 8 and on the other hand it acts as a stop for the cover 3 serves.
  • a rotor 9 is freely rotatable on the axis 8 and a bearing 8a.
  • the rotor 9 essentially has a disc-shaped appearance and is provided with an outer ring 10, which is equipped with slanted blades 11 (only partially shown in FIG. 3), their function is described below.
  • the rotor 9 also has cut-out sectors 12 which are advantageously congruent with those (6) on the housing base 5. In order to ensure that the air flow is regularly completely interrupted for a certain time while the rotor 9 is running, it is necessary to ensure that the cut-out sectors 6 and 12 are smaller in terms of angular angle than the uncut parts of the housing base 5 or the adjoining parts. of the rotor 9.
  • a part of an annular groove 13 is provided, each of which is interrupted by a web 14.
  • the housing base 5 carries a spring 15 which cooperates with a nose 16 located on the cover 3 and serves to engage in the annular groove 13 in a rotational end position of the cover 3, such that that the rotor 9 comes to a standstill when one of the Web 14 runs on the spring 15 pressed down by the nose 16.
  • the air passage of the pulsator is maximally open in this end position of the rotor 9.
  • the mode of operation of the frequency-changeable pulsator according to the invention can be described most simply with reference to FIGS. 2, 5 and 6, from which it can also be seen that the pulsator housing 1 is arranged centrally symmetrically on the side, on the one hand, two short slots 17 and which extend only over a small part of the circumference on the other hand, it has long slots 18 extending over larger regions of the circumference.
  • the cover 3 has two centrally symmetrical slots 19 in its cylindrical wall, which cooperate on the one hand with the slots 17 and 18 in the pulsator housing 1 and on the other hand with stops 20 which are integrally formed on the pulsator housing 1. By rotating the cover 3 on the pulsator housing 1, the various slots 17 and 19, respectively.
  • the nose 16 releases the spring 15 again, so that it lifts out of the annular groove 13 of the rotor 9 and releases it.
  • the air flowing through the slots 17 and 19 and 18 and 19 rotates the rotor 9 again and the air flow blown through the hair dryer starts to pulsate again.
  • each 360 ° rotation of the rotor 9 results in the air intake cross section in the pulsator housing 1 being closed and opened twice, which leads to a pulsed air flow even at the hair dryer air outlet, even when the air outlet is attached Hairdressing accessories.
  • the object on which the present invention is based is thus solved very simply and with little design effort.
  • rotor 9 and the housing base 5 can be designed differently, for example by providing three or more circular segment cutouts or other openings.
  • order of rotor 9 and housing base 5 can be reversed with respect to the direction of air flow.
  • cover 3 may also be appropriate to design the cover 3 differently and to replace the inclined plates 11 on the outer ring of the rotor 9 by curved plates.
  • the arrangement of the slots 17, 18 and 19 can also be different from the one described above, provided that the torque required for starting the rotor 9 is still achieved with the slots 17, 18 and 19 almost completely closed.
