Abstract
A hair care appliance is provided and includes a heater having a heating element, an airflow passage extending from an airflow inlet to an airflow outlet, and an air mover for moving airflow along the passage from the inlet to the outlet. The appliance further includes a thermal barrier at least partly surrounding the airflow passage so as to restrict heat transfer from the heater to an external surface of the appliance. The thermal barrier includes an inner wall proximal to the heater, an outer wall distal from the heater, and a sealed evacuated space defined between the inner and outer walls.
