An apparatus (1) for delivering hot air comprises a protection structure (2) to be fastened to a wall (4) and a delivery unit (9) set to generate a continuous air flow. The delivery unit (9) is in engagement with the protection structure (2) through a ball joint; (12, 13) so that it is movable between a rest position and an infinite number of operating positions. Associated with the ball joint (12, 13) is an electric switch which is switched over to a closed condition when the delivery unit (9) reaches one of its operating positions thereby starting said delivery unit (9). <IMAGE> |
