Abstract (en)

The hair drier (1) with differentiable airflow delivery has a casing (2) which defines a grip portion and internally accommodates a fan (5) for generating an airflow and an actuation motor (4) for operating the fan (5). The casing has two mutually spaced-apart airflow delivery outlets (10, 11). Airflow heating elements (13, 14) are provided inside the casing (2) at each of the outlets (10, 11) and can be actuated independently of one another.
