Air heating device for a hairdryer, blowing device for a hairdryer, and hairdryer comprising said devices

An air heating device for a hairdryer includes an inner tubular body with an outer surface from which a plurality of angularly spaced, radial baffles extend to define a plurality of angular sectors, a corrugated resistive coil extending around the inner tubular body, a safety device in electrical connection with said corrugated resistive coil, a thermostat in electrical connection with the corrugated resistive coil, and an outer tubular body arranged coaxially with the inner tubular body around the corrugated resistive coil. The safety device and the thermostat are respectively housed in a first and a second angular sector, which are adjacent to each other and separated by a shared radial baffle. The corrugated resistive coil two rectilinear portions positioned at the first and the second angular sector, respectively, At least one anchoring wave is interposed between the rectilinear portions and overlies said shared radial baffle.
