ABSTRACT:
A hair drying device includes a blower unit incorporating a fan and a heater for generating a hot air blow and provided at its one end with an air outlet for discharging the hot air blow. The blower unit is pivotally supported to a frame which is adapted to be mounted in or on a generally vertical wall of a room for pivotally supporting the blower unit at the other end about a horizontal axis so that the blower unit is capable of moving about the horizontal axis within a predetermined angular range between a retracted position of directing the air outlet generally vertically downwardly and an extended position of directing the air outlet outwardly and downwardly. A start position is provided offset adjacent to the retracted position so as to define within the angular range a swing range extending from the start position to the extended position. The blower unit is driven to swing within the swing range about the horizontal axis in a reciprocating manner. A control circuit is included to actuate the fan and the heater only when the blower unit swings within thus defined swing range and disable the fan and the heater while the blower unit moves between the retracted position and the start position.
