Warm air generating appliance such as hair dryer - has electric motor secured by radial ribs with slots for retaining band resistor

摘要

(1) The housing may be of plastic or lightweight metal and at the back is a lid (11) which can be removed. Air intake apertures (12) are in a circle on a solid base provided with an electric cable connection (14) and plug (15). The fan chamber (2) is open at both ends. An electric motor is inside the housing (20) and secured to it by ribs (23). The heating element (3) consists of a carrier composed of two trapeze-shaped plates (31) crossing one another at a central joint, thus forming 4 radial ribs of a heat resistant isolation material. The ribs radiate close to the outer wall of the housing and are provided at regular intervals with flat slots. These slots are the retaining points of the resistor band (34).
