Definitions

  • the present invention relates to a hairdressing appliance for curling hair which comprises a device for winding a lock of hair around a mandrel in order to achieve said curling.
  • the invention relates most particularly to a control method which makes it possible to detect any jamming of hair during the winding of the lock of hair around the mandrel and to act accordingly on the winding device, and on means electronics implementing said control method.
  • the hairdressing device comprises a fixed mandrel and a winding device allowing the winding of a lock of hair around the mandrel.
  • the winding device includes a winder and a reversible winder rotation system.
  • the configuration of the winder initially arranged in a starting position, makes it possible to grasp the lock of hair then to wind it around the mandrel under the effect of the rotation of the winder, following the start of the winding device .
  • the winder stops in its starting position once the wick has been wound, after a number of rotations of said winder, and once the winding device has been stopped by the user.
  • the hairdressing appliance comprises electronic control means which measure the rate of rotation of a motor driving the winder. When this rate of rotation does not reach a determined threshold, this indicates that an unacceptable load is applied to the winder, representative of a possible jamming of hair on the hairdressing appliance.
  • the electronic control means then reverse the direction of rotation of the motor until the winder reaches its starting position, in order to release the lock of hair and allow its removal.
  • Other hairdressing appliances for curling hair are also known, the electronic control means of which measure a defined number of rotations of the winder, for example by using a magnet placed on the winder and a magnetic field sensor placed on the body of the hairdressing device. These electronic control means are also configured to detect when the power consumed or the duration of rotation exceeds a threshold before the winder manages to make a complete turn, that is to say before the magnetic field sensor again detects the passage of the magnet.
  • the object of the present invention is to implement electronic control means that are simplified with regard to the existing prior art, and independent of variations in the operation of hairdressing appliances of the same type. Indeed, the power consumed is dependent on the adjustments and is therefore not identical between all hairdressing appliances of the same type. As a result, the difference between the nominal measurement of power consumed and the value of the consumption threshold varies between hairdressing appliances of the same type. Similarly, each motor has a rotation speed tolerance, which implies a variation in the difference between the measurement of the time between two passages of the magnet and the duration threshold between hairdressing appliances of the same type. .
  • said step of rotation in the opposite direction of the winder is triggered successively at the step of stopping the rotation of the winder, and this whatever the circumstances and the moment. It is therefore a step which is systematically triggered as soon as the control member is no longer activated.
  • a step of rotation in the opposite direction of the winder is systematically triggered successively to the step of stopping the rotation of the winder (that is to say as soon as the control member is no longer activated), the reel being rotated until it reaches a predetermined stop position.
  • a step of counting a reference unit is triggered when the rotation of the winder starts
  • the stopping step is also activated as soon as the reference unit reaches a predefined threshold value (T).
  • the latter comprises, prior to the step of rotation of the winder triggered by the activation of the control member, an initialization step in which the winder is brought into a predetermined starting position, if it does not already occupy this position.
  • This predetermined starting position allows the introduction of the lock of hair into the device hairstyle and the seizure of this lock of hair by the winder, for its winding around the mandrel.
  • the reference unit is time t.
  • the first threshold value T is greater than 3 seconds and preferably is of the order of 4 seconds.
  • the second threshold value T+Ts is between T+0.3 seconds and T+1 second.
  • this reference unit is the electrical consumption p of the motor, in this case a first consumption threshold value P and a second consumption threshold value P+Ps are fixed.
  • this reference unit is the number of turns n made by the winder, in this case a first threshold value N is preferably chosen, preferably greater than six turns.
  • the stop position of the winder corresponds to the predetermined start position, which makes it possible to be directly in the start position for placing the lock of hair in the hairdressing appliance, without requiring the performance of an initialization step.
  • the latter comprises a step of heat treatment of the lock of hair for a time (TC) which follows the stopping of the motor which occurs when the value is reached.
  • TC time
  • predefined threshold that is to say under normal curling conditions of the lock of hair.
  • the heating of the mandrel is activated during the heat treatment step.
  • the present invention also relates to a hairdressing apparatus, according to claim 11, for curling hair, which comprises a winding device comprising a mandrel and a winder configured to wind a lock of hair around the mandrel during its rotation in a predetermined direction which can be clockwise or counterclockwise.
  • This winder is driven in rotation by a motor whose operation is controlled by a control member.
  • the hairdressing appliance comprises electronic control means and means for counting a reference unit, said hairdressing appliance being configured to implement the control method which is the subject of the invention.
  • the hairdressing appliance also comprises a chuck heating system.
  • the latter comprises means for adjusting a first threshold value of the reference unit. This makes it possible to best adjust the hairdressing appliance to the length of the hair to be curled.
  • the hairdressing device comprises a system for limiting the maximum torque that can be transmitted to the winder. This helps to avoid putting too much tension on the hair in the event of a jam.
  • the hairdressing appliance comprises a warning system configured to alert the user when the torque transmitted to the winder exceeds a predefined threshold value.
  • the warning system is a mechanical clutch which produces a noise when the torque transmitted by the clutch reaches the threshold value.
  • the term “device” is used to define the hairdressing device for curling hair.

  • This toothed wheel 10 meshes with an endless screw 11 which is driven in rotation by a motor 12, which makes it possible to drive the rotation of the winder 9.
  • the direction of rotation of the motor 12 is reversible, which makes it possible to reverse the direction of rotation of the winder 9.
  • the motor 12, the toothed wheel 10 and the worm screw 11 constitute a preferred mode of design of rotation drive means 13 of the reel 9, other variants remaining possible without departing from the scope of the invention.
  • the winder 9 preferably has a conical shape which expands in the direction of the free end 7b of the mandrel 7.
  • the winder 9 comprises a notch 14, or cutout, which extends over its surface of revolution and which opens onto the free edge 15 at the second longitudinal end 9b of said reel 9.
  • This notch 14 preferably comprises a trapezoidal shape, other shapes remaining possible, for example a more or less cylindrical or oval shape.
  • the winder 9 may have a surface of revolution of cylindrical rather than conical shape.
  • Two hooks 16a, 16b are arranged facing each other in the extension of the free edge 15, at the level of the two ends 14a, 14b of the notch 14.
  • the notch 14 is positioned in the extension of the slot 4, as illustrated in figures 1 to 3 , which makes it possible to introduce the part of the lock of hair located close to the scalp, into this notch 14.
  • the rotational drive of the winder 9 then allows one of the two hooks 16a, 16b, according to the direction of rotation of the motor 12, to grab the wick to start winding it.
  • the apparatus 1 comprises a finger 17 consisting of a rigid part which is fixed at the contour 6a of the extraction opening 6.
  • This finger 17 has several functions. First of all, the finger 17 makes it possible to achieve the blocking in rotation of the wick during its winding so as to prevent the wick from rotating around the mandrel 7. In addition, this finger 17 ensures the unmolding of the curled wick without damaging it. .
  • the finger 17 is oriented more or less perpendicular to the chuck 7, with a slight spacing with respect to the free end 7b of said mandrel 7.
  • the housing 2 of the device 1 is manipulated by the manipulation handle 3, its side face 2a, which has the extraction opening 6, being positioned against the scalp during the curling operation.
  • the arrangement of the manipulation handle 3 in the extension of the slot 4, facilitates the manipulation of the device 1.
  • the device 1 comprises control means and electronic means which make it possible to manage in particular the operation of the motor 12 driving the winder 9, taking into account any hair jams that may occur during the operation of curling the lock of hair. .
  • These means also make it possible to manage a heating system (not shown) which is integrated into the mandrel 7 to heat the curl of hair wound around said mandrel 7, before it is unmolded.
  • the device 1 comprises a control member 19 which triggers a lamella switch 20 connected to an electronic box 21, when it is pressed.
  • the motor 12 is also connected to this electronic box 21.

  • the magnet 22 When the magnet 22 is positioned opposite the magnetic field sensor 23, the latter transmits information to the electronic box 21, this information indicating the position of the winder 9 which preferably corresponds to the starting position according to which the notch 14 is located in alignment with slot 4, to allow the introduction of the lock of hair into the winder 9.
  • the electronic box 21 is configured to carry out an automatic reset in said starting position, for example when the device 1 is switched on or when the control member 19 is first activated.
  • the magnet 22 and the sensor of magnetic field 23 also allow the electronic unit 21 to count the number of turns made by the winder 9 since the initial start-up of the motor 12.

  • control member 19 Any release of the control member 19, whatever the circumstances and the instant t, automatically reverses the direction of rotation of the motor 12, after a possible brief stopping time of the latter, so as to bring back the winder 9 in its starting position and thus give slack to the lock of hair, especially in the event of hair jamming.
  • the electronic box 21 stops the motor 12 once the magnetic field sensor 23 is activated, which corresponds to a return to the starting position allowing the release of the lock of hair in the event of a jam.
  • the activation of the magnetic field sensor 23 by the magnet 22 is representative of the starting position and the realization of a defined number of turns of the winder 9, according to which the curling of the lock of hair is normally finished, which automatically causes the stopping of the motor 12 in the starting position of the winder 9 and the activation of the heating system (not shown) of the mandrel 7, by the electronic box 21.
  • This step of heating the mandrel 7 corresponds to a step of heat treatment of the lock of hair during which the heat emitted by the mandrel 7 is transmitted to the hair to allow a lasting shaping of the latter. If this heating time TC is reached, the heating system is stopped and an audible signal or luminous is transmitted to the user, preferably at least one beep, to warn him that the time for heating the lock of hair is sufficient to obtain a nice shape.
  • the electronic unit 21 activates the motor 12 in the opposite direction until it returns to the position of alignment of the magnetic field sensor 23 and the magnet 22 (the position of start-up) and possibly cuts off the chuck heating system if it is not already stopped (case where the control member 19 is released before the end of the heating time TC).
  • the electronic box 21 then instantly stops the motor 12 which remains in this position as long as the user keeps the control member 19 pressed. Once the control member 19 is released, the electronic box 21 reverses the direction of rotation of the motor 12 until it returns to the starting position, before stopping the motor 12 and ending the cycle.

  • the time parameter Ts is fixed at a value between 0.3 and 1 second, so that the second time threshold value T+Ts is between T+0.3 seconds and T+1 second .
  • the sixth passage of the magnet 22 in front of the magnetic field sensor 23 occurs between the time interval T and T+Ts, for example between 4 seconds and 4.3 seconds under normal conditions of use, without jamming.
  • Other reference units can be used instead of time t.
