ABSTRACT:
A portable hair dryer comprises a flexible bonnet, a combined blower and heater power module for supplying heated air under pressure to the bonnet, and a control module for selecting the operating mode of the dryer. The power module is suspended against the back of the user by means of a pair of support straps which extend over the user's shoulders to the control module. By balancing the weights of the power and control modules, a stable condition is obtained which enables the user to perform other activities during the drying operation. The power cord of the dryer depends from the control module to assist in balancing the weights, and flexible electrical conductors in one of the support straps convey electrical power to the power module. The other support strap is removably attached to the control module to facilitate setting up and taking down the appliance. The bonnet includes an internal air duct formed by seams between its inner and outer liners for directing air to a central distribution plenum, and a plurality of radially-extending passageways similarly formed for distributing air from this plenum to the surrounding portions of the bonnet for even heat flow.
