Definitions

  • the present invention relates to a hair drier in which the air stream is generated by induction from an injector fed with compressed air, the said hair drier being particularly suitable to be employed for professional uses.
  • hair driers are employed, both for professional and domestic uses, which devices are able to generate an air stream which may also be suitably heated and conveyed for the relevant use.
  • the most diffused and known of the said devices is substantially constituted by a small fan which is driven by an electric motor provided with brushes and commutator, which motor is disposed within an adequate envelope provided with a handle.
  • the fan sucks the air through a suitable opening of the said envelope and blows it into a tubular conduit projecting from the same envelope, wherein the air coming out from the conduit may be conveyed as expected.
  • an electric heating element provided for heating the air stream and connectable on request to the supply line is disposed within the tubular conduit.
  • a change in the air stream rate of flow is often foreseen.
  • the tubular sleeve may be provided with an adequate handle and obviously it will also be provided with a suitable heating element, which may be turned on on request for heating the air stream, as well as with some devices which are able to change the air stream rate of flow.
  • the first and widely diffused kind of hair drier is usually employed both for professional and domestic uses, while the second one is essentially used for professional uses.
  • the above mentioned first kind of hair drier is considerably noisy, which fact disturbs troublesomely the persons which find themselves in the utilization area of the same, and also is quite heavy, which fact makes the operator considerably weary particularly when this hair drier is utilized for professional uses.
  • the second kind of hair drier is considerably noisy too and in addition it presents the inconvenience of being manoeuvrable with difficulty.
  • the air generator may feed solely an air drier or, utmost, a very limited number of air driers.
  • the scope of the present invention is that to overcome the above mentioned inconveniences by means of the present device which is essentially constituted by a tubular conduit, whose one end portion is provided with a nozzle fed with a quite high air pressure (at least 3 + 4 bar), the air stream coming out from the said nozzle producing the entrainment and conveyance of the ambient air into the said tubular conduit, thus producing an air stream which, coming out from the other end portion of the tubular conduit. generates a global air stream for the utilization.
  • the said tubular conduit results be extended from an adequate envelope which is provided with a suitable handle, in which envelope the said nozzle or eventually a plurality of nozzles result to be fixable on it.
  • a suitable electric heating element for heating the air stream may be disposed, as usualiy, within the said tubular conduit and control devices of per se known type may also be disposed within the handle. in order to control and/or regulate the feeding of the nozzle or nozzles for inducing air and consequently the generated air stream as well as the electric heating element turning on or off.
  • the present hair drier is basically constituted by an envelope 1 which is substantially completely similar to that one of an already known hair drier provided with electric fan.
  • the said envelope 1 comprises the cavity 11 which is provided with an opening 12 and communicating with the tubular conduit 13 and the handle 14.
  • the nozzle 2 which is suitably arranged near the inner end portion of the said tubular conduit 13.
  • the arrangement and removable fixing of the said nozzle 2 are effected by means of the support 21, which is constituted by a first central annular body 22 which is connected by the radial fins 24 to a second outer annular body 23.
  • the nozzle 2 is fixed into the hole of the said first central annular body 22. while the second outer annular body 23 engages itself against the inner surface of the cavity 11, bearing against the annular protruding portion 15 thereof which positiones it in a right manner. Then, all these elements will be fixed within the said cavity 11 by means of adequate fixing means or systems, which are not shown in the drawing.
  • the nozzle 2 is connected by means of the small pipe 25 to the valve 26a acting as intercepting and flow rate regulating valve, which valve is housed within the handle 14 together with the relevant control push button 26c, which in turn comes out from the handle 14 through the opening 14a provided on the latter and is projecting therefrom so permitting to be operated by the operator.
  • the valve 26a is connected to the flexible small pipe 3 projecting from the handle, thus resulting to be connected at a suitable free end portion thereof to a compressed air generator or an adequate compressed air feeding system, as illustrated in fig. 2 by way of example.
  • a suitable electric heating element 5 will be arranged into the tubular conduit 13 in a per se known manner, the heating element being connected by the wires 52 to the contactor 26b, which forms a sole control device together with the valve 26a.
  • the requested electncal supply is obtained by the electric cables 51, which in a first embodiment thereof have been disposed in a sheath which also contains the small pipe3.
  • control device formed by both the valve 26a and the contactor 26b then results to be simultaneously controlled by the control push button 26c, which may assume four positions corresponding to the conventional four possible operating conditions, which positions are indicated with the references I-II-III-IV always referring to fig. 1.
  • valve 26a In the position I corresponding to the not-operating condition, the valve 26a completely intercepts the compressed air feeding and the contactor 26b disconnects the heating element 5 from the electric supply line. In the position 11 the valve 26a and the contactor 26b respectively permit to have a limited compressed air feeding to the nozzle 2 and a limited electric supply to the heating element 5. so obtaining a moderate hot air stream.
  • the contactor 26b disconnects the electric heating element 5 from the supply line, while the valve 26a permits the nozzle 6 to be fed with compressed air, so obtaining a cold air stream.
  • the above mentioned hair drier operates in a simple manner, according to the already known injectors operating principle.
  • the nozzle 2 when is fed with compressed air, the nozzle 2 generates a primary air stream which is directed toward the inlet side of the tubular conduit 13, producing the suction of the air contained within the cavity 11, which air is then induced to penetrate into the same tubular conduit 13 and blown toward the free end portion thereof. from which it comes out by forming a stream which is equrvalent to that one of a conventional hair drier.
  • the hair drier is operated by acting on the push-button 26c as in a conventional hair dner.
  • Fig. 2 shows by way of example the arrangement of some hair driers 1 a of the described kind. which result to be connected by the relevant small pipes 3 to a compressed air feeding line 42, which in turn is fed by a compression unit 4.
  • connection of the small pipes 3 to the said feeding line 42 may be effected by means of convenient rap.d connectors 31, comprising also adequate means performing the connection and the electric supply of the cables 51.
  • the principal advantages of the above described hair drier are basically its remarkable lightness. permitting to diminish the fatiguing of the operator. and its silentness permitting the known troublesome inconveniences to be avoided.
