The invention is abundantly illustrated in the 16 figures of the description with reference numerals. Like all electric hair treatment apparatus, curler winder 1 of the present invention has a power supply cable 6 and an on / off switch 5 which may optionally be associated with heating and / or wind tunnel levels. croissants.

The motorized hair curler 1 of the present invention combines the heating functions of curler and motorized winding. For this purpose, it comprises heating means 19 well known to those skilled in the art such as hot air generated using a fan or a turbine and a heating resistor, heating by conduction through a heating core 26 in the rotary drum 2, or a member for induction heating by means of a coil 14. The latter two types of heating require the presence of an electronic management box (15,25) in the handle 4 of the winder 1.

Curlers 9 used should be adapted to the heating means used. Thus, for a hot air heating means 19, curlers having hot air exhaust openings will be used, whereas for the conductive heating means 19 using a heating core 26 or an induction coil. 14, use curlers 9 rather "closed" as shown in Figure 8 to ensure maximum contact between the drive drum 2 and the curler 9.

The main difficulty to combine these two functions within the same device is the size of the different elements that must be reduced to the maximum so that the device remains manageable size.

The advantage of having a heating means 19 hair curlers directly within the reel is that there is no interruption of heating curler 9. During the winding of the lock of hair around of the curler 9, the latter continues to be heated by the heating means (hot air, conduction or induction) coming from the rotary drum 2 and only stops being heated once released (unlocked) from the rotary drum 2. The method of winding a lock of hair around a hair curler 9 using the winder 1 according to the invention begins with the adaptation or locking of a curler on the drum of 2. The latch 12 of the curler 9 is on the rotating drum 2. This gesture is shown in Figure 10. Then, we put the curler-curler assembly on the lock of hair to be wound (fig.11) and switch on the winder using the rotation switch 7. The lock of hair (Figs 12 and 13) is then wound to the end. The rotational switch 7 is bidirectional, so it allows to rotate the winding drum 2 in both directions of rotation. The winder 1 according to the invention is equipped with a torsion limiter (not shown) which engages beyond a certain force torque threshold developed by the rotary drum 2 so that it stops automatically. when the wick is rolled up. The hair curler 9 is then unlocked (FIG. 14) by means of the unlocking button 8. The threshold of engagement of the torsion limiter is adjustable in order to take into account the different diameters of curler 9.

When a new hair curler 9 is fitted on the rotary drum

2, it is also possible to automatically switch on the heating means 19 of the curler 9 by a "microswitch" 11 of engagement located on the rotary drum 2. The "microswitch" 11 interlocking can also be combined with a probe temperature (not shown) for providing an extinction signal of the heating means 19 beyond a certain temperature threshold. This helps to control the risk of subjecting the hair to too high a temperature.

Depending on the choice of equipment of the apparatus, and therefore the space available in the handle 4, the motor rotating the drive drum can be placed in the handle 4 or in the rotary drum 2 itself. even. The configuration where the drive motor 16 is located within the rotary drum 2 is detailed in FIGS. 5 and 6. Here, a means for generating an air flow 18 is driven by a motor 20 and sends the air heated by the resistor 19 in the winding drum 2 which also comprises the drive motor 16 of the drum. The attachment of the motor comprises a transmission with bearing 24 and an insulator for the motor 21. The air flow represented by the black arrows in FIG. 6 is directly oriented on the curler 9, which makes it possible to bring it in and maintain it. at temperature throughout the winding operation, and even beyond.

Different curler diameters 9 may be applied to the rotary drum 2, the inner diameter of curler 9 will however be invariable in order to be adapted to the rotary drum 2 whose diameter is invariable. The Figure 1 shows curlers of different diameters possibly with air outlet openings and a sealing disc 28 which allows a preferred exit of hot air to the lock of hair and a relatively uniform distribution of heat, and therefore The hair curlers 9 comprise a driving rib 27 making it possible to fix the curler 2 on the winding drum 9. As mentioned above, the shape and the material used for the curlers must be adapted to the heating means. For induction heating, it is preferred to use curlers of the ferrometallic type, and for the conduction in general of good conducting metals. Hot air heating allows the use of a wider range of materials.

There are also various means 10 for attaching the lock of hair on the curler 9. Non-limiting examples of these attachment means 10 are shown in Figure 16.

The hair curler of the present invention may also include an ion generator 17. Such an ion generator may be particularly advantageous for laying hair curlers on dry hair. This variant will be preferred with hot air flow heating means because it allows to blow the ions directly on the curler.
