Summary of the invention

• the curler is heated in use by conduction of heat between the fixed heating core and the curler;
• the transmission comprises gears or friction drives.
• FIG. 1 represents the diagram of a simplified electrical circuit for a fixed heating core controlled by an electronic regulation of the temperature and the delay of the heating power.
• Figure 2 shows the manner of removing the hair curler of the retractor according to the invention, once the lock of hair wound by actuating the unlocking button.

• the motorized hair curler 1 of the present invention combines the heating functions of curler 2 and the motorized winding. For this purpose, it comprises a fixed heating core 3.
• Curlers 2 used should be adapted to the conduction heating means.
• a conductive heating means using a ceramic heating core or an induction coil use will be curlers 2 preferably metal large surface contact with the winder to ensure maximum contact between the core stationary heater 3 and curler 2.
• the main difficulty to combine these two functions within the same device is the size of the various elements, which must be reduced to the maximum so that the device remains manageable size.
• the advantage of having a heating means 3 curlers 2 directly within the winder 1 is that there is no interruption of heating curler 2 during the use of the winder 1 .
• it continues to be heated by conduction via the fixed heating core 3 previously carried to a temperature sufficient to bring the curler almost immediately to temperature of use.
• a delay of the heating allows the adaptation of the temperature of the curler to its diameter and the working mode of the user.
• heating core 3 "fixed", a core that must not be rotated to rotate a curler 2.
• the curler thus rotates around a heating core 3 which, him, do not turn.
• the method of winding a lock of hair around a curler 2 with the aid of the winder 1 according to the invention starts with the locking of the curler 2 on the fixed heating core 3.

• the rotational switch 1 1 is bidirectional, it allows to turn the curler 2 in both directions of rotation.
• the winder 1 according to the invention may be equipped with a torsion limiter (not shown) which engages beyond a certain force torque threshold.
• the hair curlers generally comprise means of hanging on the hair which allow them to be attached to where the rotation (loop) led them. It is possible to use for this purpose curlers provided with hooked type "Velcro", for example.
• the heating element used in a preferred embodiment of the invention is a ceramic heating element placed in the fixed core.
• the resistance of this heating element increases with temperature. It is therefore possible to have an indication of the temperature by measuring the voltage across this heating element via a divider bridge.
• the fixed core 3 is preheated to about 230 ° C. before placing the curler 2 on the apparatus 1. This makes it possible to wear the curler 2, once placed on the apparatus 1, very rapidly at about 120 ° C. by heat exchange. With metal curlers, for example aluminum, it only takes a few seconds.
• the heating power is set to maximum before being switched off when the micro-switch detects the presence of the curler but after a delay of about 20 seconds. When the absence of the curler is detected by the same micro-switch, the heating power of the device automatically returns to the maximum while waiting for the placement of the curler 2 following.
• the winder 1 according to the invention also comprises a detection of the diameter of the curler 2 for adapting the heating power to the type of curler 2 to be heated.
• the detection of presence or diameter can be done by a mechanical or electronic micro-switch located on the reel.

• connection between the ceramic heater and the electronic control is not subject to interference intrinsic to a rotating contact system.
