Abstract: 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.

Abstract: An air heating device for a hairdryer comprises an inner tubular body (2) extending along a central axis (A) and provided with an outer surface (2b) from which a plurality of mutually angularly spaced, radial baffles (4) extend so as to define a plurality of angular sectors (S), a corrugated resistive coil (6) extending circumferentially around the inner tubular body (2), a safety device (9) placed in electrical connection with said corrugated resistive coil (6), a thermostat (10) placed in electrical connection with the corrugated resistive coil (6), and an outer tubular body (16) made of insulating material and arranged coaxially with the inner tubular body (2) around the corrugated resistive coil (6).

Abstract: A hair care appliance that includes a body, a fluid flow path extending from a fluid inlet into the appliance to a fluid outlet from the body, a heater for heating fluid in the fluid flow path, a pre-heater located upstream of the heater and a thermal safety device positioned between the pre-heater and the heater. The pre-heater may include a resistive element. The pre-heater may be electrically connected to the heater via a heater circuit. The thermal safety device may be electrically connected to the heater via the heater circuit. When the appliance is activated, fluid may flow from the fluid inlet through the pre-heater, past the thermal safety device, through the heater and on to the fluid outlet. The thermal safety device may extend orthogonal to a longitudinal axis A-A of the body.
