Abstract

In an electric hairdrier in which a heating resistor (22) arranged in the air flow from a blower motor (15) is controlled by an electronic regulating device (23), the temperature of the emerging air is manually settable. In normal operation the outlet air temperature as measured by a sensor (33) remains constant at a value determined by the setting element (32), independently of the rate of air flow. However, in the event of disturbance variable occurring at the air outlet, the resulting excess of measured over desired temperature is arranged to operate a no-voltage circuit breaker (25) whose effect is to lower the effectively commanded temperature. <IMAGE> [GB2007877A]
