Definitions

• the present invention concerns an apparatus for drying hair by means of heat sources moving around the hair.
• the field of professional hair dryer devices shows, as known, a continuous growing, seeking for more and more effective solutions which could offer more freedom of action to the operator even during the treatment and, at the same time, more comfort to the
• rotating supporting element which is connected to an arm continuously oscillating between two positions that are simmetrical with respect to the vertical
• the heat flow emitted by said heat generators affects the whole hair in a regular and distributed way.
• European patent 0 317 902 discloses an apparatus in which a circular, or semicircular, radiating element, eccentrically connected to supporting means, is kept continuously rotating in the space above and behind the hair to be dried.
• the heat flow emitted by the radiating element affects the whole hair.
• the distribution of the emitted heat is not very effective, in fact the time trend of said distribution is strongly cyclic with respect to the various portions of the hair.
• the first object of the present invention to provide an apparatus allowing an effective hair drying action and having, at the same time, a structural configuration highly rationalised and simplified, with small overall dimensions and low costs for mass production.
• a further object of the invention is to provide an hair dryer apparatus with high operative flexibility, in order to accomplish, in a simply and immediate way, the various requirements of the operators in the specific technical field.
• an hair dryer apparatus wherein two radiating arms, shaped to surround the upper part and the back part of the hair, are pivoted, at one of their respective ends, into two points, next to each other, of a main supporting structure which comprises means for rotating said arms in two half-spaces opposite with respect to the median vertical plane of the apparatus according to oscillatory movements of such an extent to allow the emitted heat flow to affect the superior, the back part and side parts of the hair.
• Said supporting main structure comprises also means
• said main structure comprises separated means for rotating said two radiating arms, said
• the heat distribution through the proposed solution we can obtain, with respect to the known solutions, an indubitable advantage due to the fact that high uniformity and invariability of the heat distribution in the whole interested space is achieved by small extent heat sources movements .

• the above hair dryer apparatus operates as follows.
• the electronic control unit is simply in a standby condition, revealed by indicator light 57, and is ready to receive the control inputs concerning the operating way to perform.
• the operator can thus either select, by means of button 62, an automatic operating cycle, or can manually set various operating parameters, by means, for instance, of buttons 60 and 61 as regards the work time, by means of button 63 as regards the amount of heat produced by elements 14 , 15, and by

• the operator can also select a fixed automatic cycle, and then, can modi y some parameters, such as time, amount of heat and/or airflow produced. After that, by pushing button 55, the apparatus is put in normal operating condition, indicated by the
• the above operating way is automatically switched off at the end of the pre-set time; as well as, it can be switched off at anytime by means of button 56.
• one single actuator associated to a reduction gear having two outputs may be provided, said outputs being connected to the pivots, 23, 24, of the radiating arms.
• control panel, 54 furthermore, can be modified to be suited, for example, to separately control the actuators, according to the above described ways.
• actuators can be different from the indicated ones; in fact, continuos current step motors could be employed.
