Hair styling device

Abstract

A hair styling device (1) comprises a hair styling component (11, 13), a heating mechanism (20) configured to heat the hair styling component (11, 13), a component temperature sensor (21) configured to detect a temperature of the hair styling component (11, 13), a hair temperature sensor (22) configured to detect a temperature of hair faced by the hair styling component (11, 13) during operation of the hair styling device (1), and a controller (23) configured to receive input from at least both temperature sensors (21, 22), and to process the inputs to control operation of the heating mechanism (20) and obtain a temperature setting of the hair styling component (11, 13) in view of a moisture content of the hair estimated from at least the hair temperature.

1 . Hair styling device, comprising:
 a hair styling component configured to face hair to be subjected to a styling action by means of the hair styling device,   a heating mechanism configured to heat the hair styling component,   a component temperature sensor configured to detect a temperature of the hair styling component,   a hair temperature sensor configured to detect a temperature of hair faced by the hair styling component during operation of the hair styling device, and   a controller configured to receive inputs from at least both the component temperature sensor and the hair temperature sensor, and to process the inputs to control operation of the heating mechanism and obtain a temperature setting of the hair styling component in view of a moisture content of the hair estimated from at least the detected hair temperature.   
     
     
         2 . Hair styling device according to  claim 1 , wherein the controller is configured to derive from the input from the hair temperature sensor a value that is representative of the time duration of a styling action, and to involve the value in processing the inputs to control operation of the heating mechanism. 
     
     
         3 . Hair styling device according to  claim 1 , wherein the controller is configured to derive from the input from the component temperature sensor and the hair temperature sensor one or more of
 a value that is representative of the temperature of the hair styling component at the start of a styling action,   a value that is representative of a drop of the temperature of the hair styling component in the styling action,   a value that is representative of a drop of the temperature of the hair in the styling action,   a value that is representative of a peak temperature of the hair in the styling action,   a value that is representative of a peak temperature of the hair styling component in the styling action, and   a difference between a value that is representative of a peak temperature of the hair in the styling action and a value that is representative of a peak temperature of the hair styling component in the styling action,   
       and to involve the one or more of the values in processing the inputs to control operation of the heating mechanism. 
     
     
         4 . Hair styling device according to  claim 1 , wherein the hair temperature sensor is of the non-contact type. 
     
     
         5 . Hair styling device according to  claim 1 , comprising a pressure sensor configured to detect a clamping pressure between hair styling surfaces of the hair styling component, wherein the controller is configured to receive a pressure signal from the pressure sensor, and wherein the controller is configured to involve the pressure signal in processing the inputs to control operation of the heating mechanism. 
     
     
         6 . Hair styling device according to  claim 1 , comprising a detector configured to detect a use condition of the hair styling component, wherein the controller is configured to receive a use signal from the detector, and to derive from the use signal a value that is representative of the time duration of a styling action, and to involve the value in processing the inputs to control operation of the heating mechanism. 
     
     
         7 . Hair styling device according to  claim 6 , wherein the position detector comprises a switching mechanism configured to be in one of at least two different conditions and to be caused to switch from one condition to another as the position of the hair styling component changes. 
     
     
         8 . Hair styling device according to  claim 1 , comprising an indicator configured to provide a person with information including information related to the moisture content of the hair based on the inputs.
