Estimating the term…
A haircare appliance has a housing having an air inlet and an air outlet, an airflow generator for generating an airflow from the air inlet to the air outlet, and a heater for heating the airflow. The haircare appliance has an airflow temperature module for obtaining a value indicative of a temperature of the airflow at the air outlet, a distance sensor for sensing a distance to hair within a flow path from the air outlet and a temperature sensor for sensing a temperature of the hair. The haircare appliance has a moisture estimation module configured to estimate, based on received output values from the airflow temperature module, the distance sensor and the temperature sensor, a moisture content of the hair.
A haircare appliance comprising a housing having an air inlet and an air outlet, an airflow generator for generating an airflow from the air inlet to the air outlet, a heater for heating the airflow, an airflow temperature module for obtaining a value indicative of a temperature of the airflow at the air outlet, a distance sensor for sensing a distance to hair within a flow path from the air outlet, a temperature sensor for sensing a temperature of the hair, and a moisture estimation module configured to estimate, based on received output values from the airflow temperature module, the distance sensor and the temperature sensor, a moisture content of the hair.
A method of estimating a moisture content of hair, the method comprising directing an airflow at the hair, receiving a value indicative of a temperature of the airflow, receiving a value indicative of a distance to the hair, receiving a value indicative of a temperature of the hair, and estimating the moisture content based on the received values indicative of the temperature of the airflow, the distance to the hair and the temperature of the hair.
An attachment for a haircare appliance having an airflow generator configured to generate an airflow and a heater for heating the airflow, the airflow generator and the heater disposed in a housing, the attachment comprising an air inlet for receiving heated airflow from the housing, an air outlet, an airflow temperature module for obtaining a value indicative of a temperature of the airflow at the air outlet, a distance sensor for sensing a distance to hair within a flow path from the air outlet, a temperature sensor for sensing a temperature of the hair, and a moisture estimation module configured to estimate, based on received output values from the airflow temperature module, the distance sensor and the temperature sensor, a moisture content of the hair.
