Electric hair treatment apparatus having heated air delivery arm rotatable in conical path about the hair being treated

Abstract

A hair treatment apparatus includes a rotary arm having an air flow passage, an electric fan for blowing air through the passage to an outlet for impingement onto the hair being treated and an electric heater installed in the passage for heating the air. The rotary arm is rotatably attached at a tiltable angle to an obliquely downwardly facing body cover supported on a support rod and housing an electric motor driven drive mechanism for reciprocally rotating the arm in a path defining a conical surface about the body cover. The tilted angle of the arm is adjustable to change the apex angle of the conical surface described by the arm during rotation. The rotary drive mechanism can slip should the arm be blocked by an external force. A photo sensor position detecting arrangement controls the limits of the reciprocal rotation of the rotary arm.
