An electric hair drier comprises a shallow housing 10 having an apertured boss 11 formed on its base. An electric motor 12 drives a thin cup shaped impeller 15 which in use draws air in through apertures 14 in the boss 11 and blows air radially towards a heating coil 17 surrounding inside peripheral surface 25 of the impeller 15. The impeller has external blades 26 which in use draw air from the inside peripheral surface 25 towards a central axis of the drier at the mouth of the drier. The drier has an array of comb members 20 at its mouth. The thinness of the impeller 15 and the inherent even distribution of air passing over the coil 17 provides a hair drier which can be much thinner overall, and hence more comfortable to use, and in which the air is effectively and evenly heated. |
