Definitions

  • the invention concerns a hairstyling apparatus using steam that comprises a handheld steam treatment unit intended to treat hair with steam in order to style it.
  • the handheld treatment unit of this hairstyling apparatus is generally configured to heat hair in order to style it.
  • such a hairstyling apparatus depending on its configuration, can be used to straighten, curl, or crimp hair.
  • Various hairstyling apparatuses are known that can be used to treat hair in order to straighten, curl, or crimp it.
  • These hairstyling apparatuses comprise a handheld treatment unit consisting primarily of two arms, or jaws, each with a surface that can be flat or curved.
  • the two arms have a joint between them so as to form a clamp configured to grip hair between the two surfaces that face each other, when the two arms come together.
  • These two arms also include an area to which gripping pressure is applied in order to open and close the clamp and manipulate it during styling.
  • At least one of these two surfaces has a heating device so that hair can be heated while clamped.
  • a lock of hair is straightened by clamping the lock between the two surfaces and moving the closed clamp along the lock, from the root toward the end.
  • a lock of hair is curled by clamping the lock between the two surfaces and rolling the lock at least partially around the surfaces, with heat making the hair hold the curl.
  • the handheld treatment unit includes a means of projecting steam configured to project the steam from the first of the two surfaces to the second of the two surfaces.
  • the handheld treatment unit includes a means of aspirating the steam, located on said second surface, to evacuate the steam projected from the first surface after it passes through the lock of hair.
  • the means of projecting steam are configured to project the steam from the two surfaces that face each other during clamping.
  • the optimized design of the steam generation means allows for a steam flow rate on the order of 3-4 g/min., higher than other hairstyling apparatus designs that offer a steam flow rate of less than 2 g/min., which makes it possible to supply steam evenly to the entire length of the clamped lock of hair during steam treatment and allows that lock of hair to be rapidly steam treated as the handheld treatment unit is moved along the lock of hair.
  • This invention is intended to provide a hairstyling apparatus with performance comparable to that of the hairstyling apparatus described in document FR2967017A1 while reducing its size, for example reducing the length of the hairstyling apparatus and/or the height, for example.
  • This invention is intended to provide a hairstyling apparatus with performance comparable to that of the hairstyling apparatus described in document FR2967017A1, but using a lower steam flow rate.
  • This invention is intended to provide a hairstyling apparatus with performance comparable to that of the hairstyling apparatus described in document FR2967017A1 while simplifying its design.
  • This invention is intended to provide a hairstyling apparatus with performance comparable to that of the hairstyling apparatus described in document FR2967017A1 while decreasing its manufacturing cost.
  • This invention is intended to provide a hairstyling apparatus with performance comparable to that of the hairstyling apparatus described in document FR2967017A1 while reducing the volume of liquid used for steam generation.
  • the invention concerns a hairstyling apparatus comprising a handheld treatment unit having two arms configured to form a clamp with two surfaces that face each other, together allowing a lock of hair to be clamped.
  • the handheld treatment unit includes a means of diffusing steam configured to diffuse steam from the first of the two surfaces toward the second of the two surfaces.
  • the hairstyling apparatus includes a means of confining the diffused steam between the two surfaces clamped against each other. This means of confinement makes it possible to keep a quantity of steam in contact with the lock of hair, with even distribution, in a confinement space located between the two surfaces that are clamping the lock of hair, to provide optimal steam treatment.
  • This steam remains in the confinement space for a length of time before escaping under the steam flow action.
  • This steam confinement allows the advantage of reducing the steam flow from the means of steam generation in the handheld treatment unit.
  • the steam is provided and circulates by diffusion or projection means, and circulates with or without excessive pressure.
  • the means of steam confinement comprises a groove located in the second of the two surfaces, facing the means of diffusion. The steam passes through the lock of hair and remains confined in that groove.
  • the groove opens onto at least one of the two longitudinal edges of the second surface, so as to allow this steam to escape under the action of the steam flow exiting the means of diffusion, after having kept that steam confined in said groove.
  • the steam in the confinement space is thereby renewed. This makes it possible to maintain a level of steam pressure in the confinement space that can be essentially constant.
  • the groove is between 2 and 6 mm wide, preferably 2.5 mm, and between 0.5 and 2 mm deep, preferably 1 mm. These dimensions allow the confinement space to be optimized so as to maintain a sufficient amount of renewed steam in contact across the width of a lock of hair in order to style it.
  • the groove is between 20 and 220 mm long, preferably 90 mm, so as to optimize the volume of the confinement space for a lower steam flow rate of 0.5 to 2 g/min., preferably between 0.9 and 1.2 g/min.
  • the first surface contains a furrow with a bottom surface, wherein the means of steam diffusion is placed so as to diffuse the steam from that bottom surface, and the means of steam confinement comprises the furrow, in addition to or even in substitution of the aforementioned groove located in the second of the two surfaces.
  • the invented hairstyling apparatus includes both a groove and a furrow as described above, the groove is located facing the furrow.
  • the groove and the furrow preferably have essentially identical volumes.
  • the first surface has two adjoining furrows, each with a bottom surface, and the means of diffusion are placed so as to diffuse the steam from at least one of those two bottom surfaces.
  • the groove is placed so as to face the two furrows.
  • At least one furrow opens onto at least one of the two longitudinal edges of the first surface, which allows steam to escape after having been diffused and held in the confinement space.
  • the means of steam diffusion includes multiple diffusion orifices located along the bottom surface of at least one furrow. In one variation, this means of steam diffusion includes a diffusion slot located on the bottom surface of at least one furrow.
  • the invented hairstyling apparatus has a single furrow with a curved shape.
  • the groove has a rounded grid whose form matches said curved furrow. This contributes to better distribution of the steam onto the lock of hair while keeping it under tension as the handheld treatment unit holding the lock of hair is moved.
  • the invented hairstyling apparatus has a furrow and a groove that are circular in shape, so as to form a cylinder when the clamp is in closed position.
  • the hairstyling apparatus includes a perforated roller mounted so as to rotate inside of that cylinder. This allows steam to be distributed into the confinement space constituted by said cylinder, with the rotation of the roller preventing the lock of hair from being pulled as the handheld treatment unit is moved along the lock of hair.
  • the means of steam confinement are off-center on the surfaces. It must be understood that the means of confinement are not in the middle of the surfaces but rather upstream or downstream on the surfaces. More precisely, the means of confinement can be in the form of a confinement system that is off-center on the treatment surface, for example a single assembly formed at least by the groove that is off-center on the treatment surface or straightening plate with respect to its median plane and crosses it orthogonally.
  • each of the two surfaces has a heating plate, and those heating plates are located facing each other and together can clamp a lock of hair. This allows heat treatment of the lock of hair at the same time as steam treatment.
  • the means of steam confinement are located between the two heating plates. This offers the advantage of heating the steam that is present in the confinement space.
  • the means of steam confinement are off-center on the downstream parts of the heating plates, which allows the lock of hair to be steam-treated before it is heat-treated, as the handheld treatment unit is moved along the lock of hair.
  • the median line of the means of confinement is located at a distance d 1 from the downstream edge of the heating plates, and the ratio of the distance d 1 to the width l 1 of the heating plates is between 0.1 and 0.4.
  • a comb is located downstream of one of the surfaces. This makes it possible to untangle and aerate the lock of hair before it is steam-treated, thus promoting the passage of steam through the hair.
  • the invented hairstyling apparatus includes a steam shut-off that is configured to block the steam escaping from the means of confinement in the direction of the proximal part of the clamp, with said proximal part configured for manipulating the handheld treatment unit. This protects the hand that is manipulating the handheld treatment unit against steam burns.
  • the means of steam diffusion are configured so as to deliver a steam flow rate between 0.5 g/min. and 2 g/min., preferably between 0.9 g/min. and 1.2 g/min.
  • a steam flow rate between 0.5 g/min. and 2 g/min., preferably between 0.9 g/min. and 1.2 g/min.
