Abstract
Hairdryer device (10) of the type equipped with at least one handle (2), with at least one dispensing barrel (3), with at least one electric motor (4) and with at least one inlet fan (5) functionally connected to the motor (4) to take in air from the outside and dispense it through an outlet mouth. The device also has a first outlet mouth (12) arranged on the front of barrel (3), at least one second outlet mouth (13), arranged on the side of barrel (3) to dispense an airflow substantially perpendicular to the first outlet mouth (12) and selection means (14) to alternate the dispensing of the flow between the first and second mouth according to the user's requirements.
Description
- 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.
- From observing the posture and movement of the arms of hairdressers whilst using conventional hairdryers, like the one described above, it can be seen that when straightening hair the hairdresser is forced to lift the arm and twist the wrist to direct the airflow from above to below.
- Such an operation becomes necessary, during straightening of hair, to make the hair shiny, since by directing the hot airflow from the top of the head towards the tips of the hair the squamae of the hair close up, which makes them shiny.
- In order to be able to carry out this type of drying, in the current state of the art, it is necessary to add an accessory (air concentrator) on the end of the hairdryer. This element has a series of disadvantages in terms of comfort:
-
- on the one hand it does not solve the ergonomic problems, since the grip and the arm and wrist movements remain unnatural (lifting of the arm and twisting of the wrist) and even made more tiring by the extension of the hairdryer that means that the arm has to be lifted even higher;
- on the other hand, by absorbing the heat from the air coming out from the end of the hairdryer, the air concentrator overheats with the risk of burning the fingers when it has to be held to detach it, and then move on to a different operation.
- These and other factors, above all considered over a continuous day of work lasting about eight hours lead to needless tiring that can, over time, cause serious and temporarily incapacitating pathologies such as tendinitis.
- Indeed, prolonged and/or repetitive flexing-extension movements of the wrist cause an increase in pressure inside the carpal tunnel.
- Moreover, 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.
- In light of the above there is clearly a need to provide a hairdryer device, like the one according to the present invention, which allows the problems of the prior art to be solved by providing a device capable of varying the type and direction of the airflow being dispensed according to the type of drying and the degree of shine that one wishes to obtain.
- 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.
- Finally, another purpose of the present invention is to provide a hairdryer device that is particularly simple and functional at a relatively low cost.
- These and other purposes according to the present invention are accomplished by a hairdryer device as outlined in
claim 1. - Further characteristics of the device are the object of the dependent claims.
- The characteristics and advantages of a hairdryer device according to the present invention shall become clearer from the following description, given as a non-limiting example, referring to the attached schematic drawings, in which:
-
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; and -
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; and -
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. - With reference to the figures, a hairdryer device is shown, wholly indicated with 10.
- The
device 10 comprises at least onehandle 2, at least one dispensingbarrel 3 arranged substantially perpendicular to thehandle 2, anelectric motor 4 and at least oneinlet fan motor 4 to take in air from the outside and dispense it through an outlet mouth. - In order to operate, 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 oneelectrical resistance 8 arranged downstream of theelectric motor 4 to heat, if so desired, the airflow to be dispensed and at least onefilter 9 arranged upstream of theintake fans - Advantageously, according to the present invention the
device 10 also comprises at least onefirst outlet mouth 12 arranged on the front ofbarrel 3, at least one secondair inlet mouth 13 arranged on the side ofbarrel 3 to dispense an airflow, substantially perpendicular to thefirst mouth 12 and selection means 14 to alternate the dispensing of the flow between the first 12 and thesecond 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 thebarrel 3 and consists of a blade-shaped opening 11, in other words of a size substantially larger than the rest, as shown inFIG. 2 a. - In particular, the predominant direction is that parallel to the axis of symmetry of the
barrel 3. The special blade-shaped configuration of theopening 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 projectingportion 15 with section substantially radially converging going away from thebarrel 3, as shown inFIG. 2 . - The blade-
shaped opening 11 is arranged on top of the projectingportion 15. - On the inclined sides of the projecting portion 15 a plurality of
holes 17 are foreseen that are also inclined, which by Venturi effect, during the operation of thedevice 10, take in cold air from the outside so as to compact the flow being dispensed from thesecond outlet mouth 13. - The cold air coming from the outside mixes, therefore, with the hot air coming from the
barrel 3 compacting the flow being dispensed and, therefore, resulting in the squamae of the hair closing to a greater extent, which make them shinier. - To better direct the flow entering through the
holes 17, a deflectingfin 32 is foreseen, as shown inFIG. 2 , arranged perpendicular to theopening 11. - The alternation between the dispensing of the two air flows occurs, as stated earlier, thanks to suitable selection means 14 or selectors actuated by
suitable controls 16. - According to a first embodiment shown in
FIG. 1 , the selection means 14 are represented by acurtain element 20 that can slide in twoguides 21 formed inside thebarrel 3 to close or open the firstfront outlet mouth 12. - The sliding of the
curtain 20 is obtained throughcontrol means 16 represented, in this case, by amechanical connection member 22 and by at least oneslider 23 arranged on thehandle 2 and able to be actuated manually from the outside. - By making the
slider 23 slide in one direction, thecurtain 20 slides in theguides 21 to close thefront outlet mouth 12, whereas by making theslider 23 slide in the opposite direction, thecurtain 20 slides back to open thefront outlet mouth 12. - Although in the present description reference is made to two
side guides 21 it is also possible to foresee just one or more than two of them without departing from the scope of protection of the present invention. - According to another embodiment, the selection means 14 are represented by a
diaphragm 31 arranged at thefirst outlet mouth 12. - The
diaphragm 31 is hinged at an end thereof to thebarrel 3 and can rotate between a closed position and an open position to open or close thefirst outlet mouth 12. - For this purpose, the diaphragm has a shape and size such as to completely block the
first outlet mouth 12 in closed position. - According to this embodiment, the
diaphragm 31 is held in open position by suitableelastic means 33, and in closed position by suitable locking means, not shown, suitable for locking said diaphragm onto themouth 12 and counteracting saidelastic means 33. - With the locking means unlocked, the
diaphragm 31 rotates under the action of the elastic means to leave thefirst outlet mouth 12 free to dispense the airflow at the front. - Alternatively, the
diaphragm 31 can be hinged at two of its opposite ends to thebarrel 3 so as to define a rotation axis that is substantially vertical, in other words substantially parallel to thehandle 2, or horizontal, in other words perpendicular to thehandle 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 inFIG. 4 ), in which it is arranged parallel to the airflow so as to allow it to be dispensed from themouth 12. - According to yet another embodiment, not shown, 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.
- According to yet another embodiment, 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. - In particular, when the deflectors are arranged at 90° to one another air passes, whereas when the blades come together the passage of air is blocked.
- According to yet another embodiment, the selection means 14 of the air are represented by a plurality of
bladed air deflectors 44 hinged to thebarrel 3 so as to be able to rotate between a position in which they are arranged perpendicular to the airflow, forming asingle 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). - Alternatively, the reciprocity between the two flows can also be obtained by providing a portion of
barrel 3 shaped like a rotatable sleeve. - In particular, the aforementioned sleeve, arranged at the end of the
barrel 3, can rotate to open or close theopening 11. - In any case, once the front curtain or the alternative selection means 14 that opens the
first outlet mouth 12 is open, it is not necessary to close thesecond outlet mouth 13, arranged on the side of thebarrel 3. Indeed, the force of the airflow directed towards the front outlet is unable to create an airflow from the underlyingsecond outlet mouth 13. Rather, due to the Venturi effect, the main flow directed towards the front air outlet orprimary 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 theresistance 8, and the cold one, coming in from themouth 13, respectively. - According to another advantageous aspect of the present invention, 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 thedevice 10 to be configured with a particularly slim tube-shaped structure. Thehairdryer 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. - In other words, with the
device 10 according to the present invention, 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.
- Alternatively, it is possible to foresee a conventional
electric motor 4 that must, however, be positioned inside the 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 hairdryer device according to the present invention, in a variant that is not shown, foresees that both the
first outlet mouth 12, and thesecond outlet mouth 13, be positioned on a sleeve able to rotate by 360° on thebarrel 3. In this way, an airflow is obtained dispensed from themouth 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. - At the third outlet mouth 12 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.
- From the description that has been made the characteristics of the device object of the present invention are clear, just as the relative advantages are also clear, including:
-
- possibility of carrying out the hair treatment process (straightening, smoothing, brushing, etc.) allowing the wrist to remain in the most natural possible position, i.e. the one in which the muscles are typically relaxed;
- possibility of keeping the device upright on a plane without the help of external support means;
- simplicity of construction and functionality;
- relatively low manufacturing costs.
Finally, it is clear that the device thus conceived can undergo numerous modifications and variations, all of which are covered by the invention. For example, although in the present description theoutlet mouths barrel 3 it is, nevertheless, possible to make them on a distinct portion able to be fixed through suitable releasable means to thebarrel 3 itself so as to obtain the same result in functional terms. Moreover, all of the details can be replaced by technically equivalent elements. In particular, it is possible within the present invention to make a hairdryer accessory, such a hairdryer comprising at least one dispensingbarrel 3 to which such an accessory can be fixed through attachment means. Such an accessory comprises afirst outlet mouth 12, arranged on the front of saidbarrel 3, and at least onesecond outlet mouth 13, arranged on the side of saidbarrel 3 to dispense an airflow, substantially perpendicular to saidfirst mouth 12. Moreover, it is possible to foresee the presence of at least one third mouth for the air arranged at the top of such abarrel 3. Moreover, the attachment means between the barrel and the accessory allow it to rotate with respect to such a barrel.
In practice, the materials used, as well as the sizes, can be whatever according to the technical requirements.
