Definitions

  • the present invention refers to a hairdryer device.
  • Conventional hairdryer devices are made up of a handle, a dispensing barrel arranged substantially perpendicular to the handle, an electric motor, contained in the barrel and an inlet fan functionally connected to the motor to take in air from the outside and dispense it, possibly after having passed through an electrical resistance, from an outlet mouth, arranged on the front of the barrel.
  • the repeated stretching of the nerves and of the tendons that run behind the tunnel can cause inflammation that reduces the size of the carpal tunnel resulting in the compression of the median nerve.
  • the purpose of the present invention is, therefore, to avoid the aforementioned drawbacks and in particular to make a hairdryer device that allows the hair treatment process (straightening, smoothing, brushing, etc.) to be carried out allowing the wrist to remain in the most natural possible position, i.e. the one in which the muscles are typically relaxed (which occurs in conditions of microgravity).
  • Another purpose of the present invention is to provide a hairdryer device, which eliminates the possibility of burning the fingers due to the removal of the air concentrator, before it has cooled down.
  • Another purpose of the present invention is to provide a hairdryer device capable of being positioned on a support base without auxiliary support elements, thus capable of standing upright.
  • Another purpose of the present invention is to provide a hairdryer device that is particularly simple and functional at a relatively low cost.
  • FIG. 1 is a schematic side elevation view in section of a first embodiment of the hairdryer device according to the present invention
  • FIG. 2 is a schematic front view in section of a first embodiment of the hairdryer device according to the present invention
  • FIG. 2 a is a schematic view from below of the blade-shaped opening of the hairdryer device according to the present invention.
  • FIG. 3 is a schematic side elevation view in section of a second embodiment of the hairdryer device according to the present invention.
  • FIG. 4 is a schematic side elevation view in section of a further embodiment of the hairdryer device according to the present invention equipped with special selection means of the airflow;
  • FIGS. 5 and 5 a are two front views of a further embodiment of the hairdryer device according to the present invention equipped with special selection means of the airflow.
  • a hairdryer device is shown, wholly indicated with 10.
  • the device 10 comprises at least one handle 2 , at least one dispensing barrel 3 arranged substantially perpendicular to the handle 2 , an electric motor 4 and at least one inlet fan 5 , 5 ′ functionally connected to the motor 4 to take in air from the outside and dispense it through an outlet mouth.
  • the hairdryer device 10 has a connection to an energy source, such as, in a known way, a connection, not shown, to the mains.
  • the device 10 also has, in a per se known way, at least one electrical resistance 8 arranged downstream of the electric motor 4 to heat, if so desired, the airflow to be dispensed and at least one filter 9 arranged upstream of the intake fans 5 , 5 ′.
  • the device 10 also comprises at least one first outlet mouth 12 arranged on the front of barrel 3 , at least one second air inlet mouth 13 arranged on the side of barrel 3 to dispense an airflow, substantially perpendicular to the first mouth 12 and selection means 14 to alternate the dispensing of the flow between the first 12 and the second outlet mouth 13 according to the type of drying that one wishes to obtain.
  • the secondary outlet mouth 13 is arranged on the side of the barrel 3 and consists of a blade-shaped opening 11 , in other words of a size substantially larger than the rest, as shown in FIG. 2 a.
  • the predominant direction is that parallel to the axis of symmetry of the barrel 3 .
  • the special blade-shaped configuration of the opening 11 allows the closing of the squamae of the hair during drying to be made easier and to be carried out to a greater degree, making the straight hair particularly shiny.
  • the second outlet mouth 13 also has a projecting portion 15 with section substantially radially converging going away from the barrel 3 , as shown in FIG. 2 .
  • the blade-shaped opening 11 is arranged on top of the projecting portion 15 .
  • a plurality of holes 17 are foreseen that are also inclined, which by Venturi effect, during the operation of the device 10 , take in cold air from the outside so as to compact the flow being dispensed from the second outlet mouth 13 .
  • a deflecting fin 32 is foreseen, as shown in FIG. 2 , arranged perpendicular to the opening 11 .
  • the selection means 14 are represented by a curtain element 20 that can slide in two guides 21 formed inside the barrel 3 to close or open the first front outlet mouth 12 .
  • control means 16 represented, in this case, by a mechanical connection member 22 and by at least one slider 23 arranged on the handle 2 and able to be actuated manually from the outside.
  • the curtain 20 slides in the guides 21 to close the front outlet mouth 12 , whereas by making the slider 23 slide in the opposite direction, the curtain 20 slides back to open the front outlet mouth 12 .
  • the selection means 14 are represented by a diaphragm 31 arranged at the first outlet mouth 12 .
  • the diaphragm 31 is hinged at an end thereof to the barrel 3 and can rotate between a closed position and an open position to open or close the first outlet mouth 12 .
  • the diaphragm has a shape and size such as to completely block the first outlet mouth 12 in closed position.
  • the diaphragm 31 is held in open position by suitable elastic means 33 , and in closed position by suitable locking means, not shown, suitable for locking said diaphragm onto the mouth 12 and counteracting said elastic means 33 .
  • the diaphragm 31 rotates under the action of the elastic means to leave the first outlet mouth 12 free to dispense the airflow at the front.
  • the diaphragm 31 can be hinged at two of its opposite ends to the barrel 3 so as to define a rotation axis that is substantially vertical, in other words substantially parallel to the handle 2 , or horizontal, in other words perpendicular to the handle 2 .
  • the diaphragm 31 can, therefore, rotate between a closed position, in which it is arranged perpendicular to the airflow and blocks the first outlet mouth 12 ( FIG. 4 ) and an open position (represented for example with a broken line in FIG. 4 ), in which it is arranged parallel to the airflow so as to allow it to be dispensed from the mouth 12 .
  • the selection means 14 of the airflow are represented by at least one butterfly valve consisting of two semicircular sections hinged at the straight sides.
  • the two semicircular sections open and close thanks to a mechanical connection member arranged on the body of the hairdryer and to a manual gripping element actuated from the outside.
  • the selection means 14 of the air are represented by two bladed air deflectors suitable for lying on top of one another or coming together to open or close the outlet of the airflow through the first mouth 12 .
  • the selection means 14 of the air are represented by a plurality of bladed air deflectors 44 hinged to the barrel 3 so as to be able to rotate between a position in which they are arranged perpendicular to the airflow, forming a single shutter 31 that blocks the first outlet mouth 12 ( FIG. 5 ) and an open position in which they are all arranged parallel to each other and to the airflow so as to allow the latter to be dispensed from the mouth 12 ( FIG. 5 a ).
  • the reciprocity between the two flows can also be obtained by providing a portion of barrel 3 shaped like a rotatable sleeve.
  • the aforementioned sleeve arranged at the end of the barrel 3 , can rotate to open or close the opening 11 .
  • the front curtain or the alternative selection means 14 that opens the first outlet mouth 12 is open, it is not necessary to close the second outlet mouth 13 , arranged on the side of the barrel 3 . Indeed, the force of the airflow directed towards the front outlet is unable to create an airflow from the underlying second outlet mouth 13 . Rather, due to the Venturi effect, the main flow directed towards the front air outlet or primary mouth 12 creates a cold airflow that penetrates from the outlet below 13, determining a suitable mixing of the two airflows—the hot one, coming from the resistance 8 , and the cold one, coming in from the mouth 13 , respectively.
  • the electric motor 4 is a single-phase or three-phase electronic motor with electronic control.
  • the particular motor 4 is of a particularly small size that allows the device 10 to be configured with a particularly slim tube-shaped structure.
  • the hairdryer device 10 according to the present invention thus consists of a new electronic motor of reduced diameter that can be controlled through an electronic board capable of modulating the dispensing speed of the airflow as desired.
  • the airflow is not dispensed at determined speeds, but in continuous variation according to the user's requirements.
  • the small size of the new electronic motor allows it to be positioned inside a handle, allowing the barycentre to be moved from the body of the barrel (as in conventional hairdryers) to the area of the grip or handle.
  • the movement of the barycentre which is now substantially aligned with the axis of symmetry of the handle, makes it possible to have a product that is able to be rested on the base of the handle and to remain stable, upright on a plane, making it easier to be held more ergonomically at the moment of use.
  • the hairdryer device according to the present invention in a variant that is not shown, foresees that both the first outlet mouth 12 , and the second outlet mouth 13 , be positioned on a sleeve able to rotate by 360° on the barrel 3 . In this way, an airflow is obtained dispensed from the mouth 13 with variable inclination according to the user's requirements.
  • the hairdryer device in a further variant that is not shown, also foresees a third outlet mouth of the air arranged in the top part of the barrel 3 .
  • a second integrated accessory intended for the treatment of curly hair is foreseen.
  • the integrated accessory is represented by a diffuser provided with a plurality of silicon rubber-ended points suitable for carrying out a massage and a further curling of the root of the hair.
  • the integration of this second accessory in the very structure of the hairdryer device allows the risks of burning hands and fingers whenever touching the air nozzle and/or the diffuser before the hairdryer has cooled down to be eliminated.
