Abstract: A hair styling appliance for dual supply voltage operation is described comprising a body having at least one arm bearing a hair styling heater (560), wherein the hair styling heater comprises one or more heater electrodes (630,632,634,636) for heating the hair styling heater. A first power input is connectable to a battery power source (564) and a second power input is connectable to a mains powered source (561). The first power input and the second power input are each coupled to at least one of the one or more heater electrodes. Such a hair styling appliance is useable for styling when coupled to the mains powered source and when coupled to the battery power source increasing the versatility of the appliance.

Abstract: A hair dryer (10) has a hand-held housing comprising an air inlet (12), an air outlet (14), a motor (1) between said air inlet (12) and said air outlet (14) to draw air in from said air inlet (12) and drive air out from said air outlet (14). A heating element (17) is located in said air flow between said air inlet (12) and said air outlet (14). The hair dryer (10) further comprises a filter on said air inlet (12). The filter comprises a metal filter plate (20) bearing a plurality of holes, wherein at least some of said holes have a maximum lateral dimension of less than 1.5 mm and wherein vertical walls of said holes through a thickness of said filter plate are substantially straight or at least partially concave.

Abstract: The invention relates to hair dryers. Various techniques for improving air flow in hair dryers are described, including a hair dryer providing laminar flow air. In another variant a hair dryer has a two air flow channels: one a hot air channel the other a cool air channel, with the cool air channel circumscribing the hot air channel. The nozzle end of the hair dryer is arranged such that the cool air channel extends forward of the hot air channel outlet. This allows a hair dryer to be placed close to, or on, a person's hair/head without and risk of burning the person's head. A hair dryer with external power supply is also described which reduces the weight of the housing held by a user.

Abstract: A hair styling apparatus having a pair of closable jaws to engage a user's hair. The jaws have complementary shapes with a first said jaw defining a curved ridge and a second said jaw defining a curved recess. One or both of the jaws includes a heater such that, when said jaws are closed, hair is heated in a heating region between the ridge of the first jaw and the recess of said second jaw. The second jaw has a curved longitudinal surface having an active cooling region. The heating region is located on the forward curve and the active cooling region is located on the reverse curve.

Abstract: A hair dryer comprising: a housing defining a first air flow channel and a second air flow channel, whereby the first air flow channel at least substantially circumscribes the second air flow channel; an air flow regulation means to regulate the flow of air along the first air flow channel and/or the second air flow channel.

Abstract: A hair styling appliance for dual supply voltage operation is described comprising a body having at least one arm bearing a hair styling heater (560), wherein the hair styling heater comprises one or more heater electrodes (630,632,634,636) for heating the hair styling heater. A first power input is connectable to a battery power source (564) and a second power input is connectable to a mains powered source (561). The first power input and the second power input are each coupled to at least one of the one or more heater electrodes. Such a hair styling appliance is useable for styling when coupled to the mains powered source and when coupled to the battery power source increasing the versatility of the appliance.

Abstract: The application describes hair styling apparatus (1) for creating volume in a user's hair. The hair styling apparatus (1) comprises a heating member, a cooling member adjacent to the heating member, thermal insulation between the cooling member and the heating member and a tensioning member projecting from the heating member. The heating member comprises a heating contacting surface for heating hair in contact with the heating member. The cooling member has a cooling contacting surface for cooling hair in contact with the cooling member and the cooling member is cooled by an active cooling mechanism. The tensioning member tensions a user's hair against the heating contacting surface to improve heat transfer into a user's hair and applies stress to a user's hair as the hair contacts the cooling contacting surface adjacent the heating contacting surface whereby the hair is styled to create volume.

Abstract: A hair styling apparatus includes a plurality of heater electrodes which heat one or more hair styling heaters, a power source for powering the plurality of heater electrodes and a controller configured to control powering of the plurality of heater electrodes from the power source. The plurality of heaters includes a first subset and a second subset of heaters. The controller is configured to, in a first mode of operation; control the power source so that the first and second subsets are not simultaneously powered.

Abstract: A hair styling apparatus including a first and a second arm moveable between a closed position in which a contacting surface of the first arm is adjacent a contacting surface of the second arm and an open position in which the contacting surfaces of each arm are spaced apart, whereby the contacting surfaces of each arm have complementary profiles so that, in use, a section of hair is clamped between the contacting surfaces when the arms are in the closed position, and where a heating zone on at least one of the contacting surfaces is provided to heat the section of hair between the contacting surfaces, a cooling zone on at least one of the contacting surfaces is provided for cooling the section of hair after the section of hair has been heated, and the cooling zone is curved whereby, in use, as the hair styling apparatus is moved along the section of hair in a generally linear fashion, the section of hair is curled.

Abstract: A hair styling apparatus comprising a pair of closable jaws (20,22) to engage a user's hair. Said jaws (20,22) have complementary shapes with, a first said jaw (20) defining a curved ridge and a second said jaw (22) defining a curved recess. One or both of said jaws (20,22) includes a heater such that, when said jaws are closed, hair is heated in a heating region (16) between the ridge of said first jaw (20) and the recess of said second jaw (22). Said second jaw (22) has a curved longitudinal surface having an active cooling region (14). A transverse cross section through said second jaw (22) defines at least one S-shaped curve having a forward curve into which said ridge of said first jaw (20) fits, and a linked reverse curve bearing said active cooling region (14) on which hair may be cooled and curved. Said heating region (16) is located on said forward curve; and said active cooling region (14) is located on said reverse curve.
