A hair dryer has a primary air flow path and a secondary air flow path. The primary air flow path is operable to dry hair using suction in a first mode of operation. The secondary air flow path is operable to blow dry hair in a second mode of operation. In the primary mode of operation, the motor and fan assembly of the secondary air flow path is operated in reverse to direct air towards hair that is being dried by suction.

A household appliance has an air flow path extending from an air inlet to an air outlet with a fan and motor assembly in the air flow path. The fan and motor assembly comprises a motor drivingly connected to a rotating fan blade subassembly. The fan and motor assembly is adjustable between a first configuration in which the rotating fan blade subassembly provides a first level of air flow and a first level of suction and a second configuration in which the rotating fan blade subassembly provides a second level of air flow and a second level of suction wherein the first level of air flow is higher than the second level of air flow and the second level of suction is higher than the first level of suction.

A portable hand held hair dryer has a heating element has a longitudinally extending heating element and a plurality of fins that are press fitted onto the heating element whereby a collar of the fins is deformed to secure the heating member in the fins.

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). The safety device (9) and the thermostat (10) are respectively housed in a first (S1) and a second angular sector (S2), which are adjacent to each other and separated by a shared radial baffle (11), and the corrugated resistive coil (6) comprises a plurality of first turns (7a) provided with two rectilinear portions (12) positioned at the first (S1) and the second angular sector (S2), respectively, and at least one anchoring wave (8) interposed between the rectilinear portions (12) and overlying said shared radial baffle (11).

A portable hair drying assembly for drying a user's hair includes a bowl that is wearable on a user's head thereby facilitating the bowl to be in thermal communication with hair on the user's head. The bowl has an air chamber that is positioned within the bowl and a plurality of air apertures that is each in fluid communication with the air chamber. A housing is removably coupled to the bowl and the housing has an intake and an exhaust. The exhaust is in fluid communication with the air chamber when the housing is removably coupled to the bowl. A blower is positioned within the housing to blow air onto the user's hair when the bowl is worn on the user's head. A heating unit is positioned within the housing to heat the air being blown by the blower thereby enhancing drying the user's hair.

A wireless negative ion hair care cap comprises an air permeable pliable cover body, at an opening thereof is disposed an elastic band for the wireless negative ion hair care cap to fit tightly around a human head, on the inner periphery thereof are disposed electric heating elements and at least a negative ion generator, and on the outer periphery thereof are disposed a controller having an electric circuit and a holding for a battery to be placed therein. The controller is to set up a time and temperature and to control the electric heating elements and negative ion generator for releasing heat and negative ions. The generated heat and negative ions are transferred to an inside of the pliable cover body and are evenly distributed therein to apply heat to the hair on the human head.
