Abstract

The appliance for treating the hair, having two arms to be closed over the hair to be treated, at least one of the arms carrying a refill of hair treatment product, the appliance having an electronic control circuit with an electronic memory, this circuit being designed to detect the closure of the arms and the fitting of the refill, the appliance having a steam generator for outputting steam onto the hair and at least one heated straightening plate, the appliance being designed to increment a variable in the memory during the use of the appliance after the refill has been changed and to pass into a downgraded mode of operation in which the operation of the steam generator and/or of the straightening plate is modified when the variable exceeds a first predefined threshold.

First claim

The invention claimed is:

1. An appliance for treating the hair, comprising:
two arms to be closed over the hair to be treated, at least one of the arms carrying a refill containing a hair treatment product to be applied to the hair;
an electronic control circuit comprising an electronic memory, the electronic control circuit being designed to detect a closure of the arms and a fitting of the refill on the appliance;
a steam generator for outputting steam from a liquid water reservoir of the device onto the hair; and
at least one heated straightening plate,
the electronic control circuit being designed, when the electronic control circuit detects the fitting of a refill on the appliance, to store and increment in the electronic memory a variable representing at least a number of the closure of the arms detected by the electronic control circuit and, when said variable exceeds a first predefined threshold, to move the appliance into a downgraded mode of operation, the operation of the steam generator being interrupted and/or the temperature of the straightening plate being modified in the downgraded mode of operation.

2. The appliance according to claim 1 , wherein the temperature adjustment range of the straightening plate is reduced in the downgraded mode compared with operation in a non-downgraded mode.

3. The appliance according to claim 1 , wherein the variable incorporates a time for which the arms are closed over the hair.

4. The appliance according to claim 1 , wherein said variable is reset when the refill is changed.

5. The appliance according to claim 1 , which is designed to pass into the downgraded mode when said variable exceeds a second predefined threshold, different from the first predefined threshold over several uses between which a power supply to the appliance is disconnected.

6. The appliance according to claim 1 further comprising a contactor actuated by the refill fitted on the arm.

7. The appliance according to claim 1 , wherein the refill includes a porous substrate impregnated with a cosmetic composition.

8. The appliance according to claim 1 further comprising a contactor carried by one of the arms between a head of the arms and an articulation.

9. The appliance according to claim 1 , wherein a value of the variable is preserved when the appliance is switched off without disconnection of a power source to the appliance.

10. The appliance according to claim 1 , further comprising a locking member configured to cooperate with an element of the refill to mechanically prevent the fitting of the refill that has previously been used and then removed.
