ABSTRACT:
There is disclosed a hand held pan shaped, infrared hair dryer containing a perforated air diffuser which can function as an infrared reflector if the air diffuser is shiny. The air diffuser also protects a quartz tube infrared emitter. A fan rotated by a motor causes air to flow through the perforations in the air diffuser and out the air outlet in a uniform airflow. The perforations are patterned so the airflow is uniform and negative airflow is essentially avoided. The infrared radiation is emitted by a quartz tube containing a wire resistance heater.
