Description

  The present invention relates to a hair styling device intended for styling hair using steam and in particular for smoothing, curling and crimping human hair.

  Traditionally, there are two types of hair styling devices that allow smoothing or curling or crimping, the surface of which the hair is gripped is flat or curved or corrugated, heated or heated.

  A gripping type device for smoothing or curling generally comprises two pivoting jaws, each having an end that supports a treatment surface, at least one of the treatment surfaces being heated, The other is provided so that the hair is brought into contact with the treatment surface of the former, that is, the hair is brought into contact with the heating portion by moving the jaw that allows the insertion of the hair from the open position to the closed position.

  The other end of the jaw acts as a holding area and forms two half handles that allow changing from the open position to the closed position. This transition is done manually by pressing the two connected half handles of the device towards each other and bringing the heating part into contact with the hair. Smoothing the hair tress is accomplished by moving the device along the tress from the root to the tip. Curling the hair strands is accomplished by winding the strands at least partially around one or the other of the treated surfaces and applying heat to secure the curls to persist. It is likewise possible to use vapor released to the hair in order to improve the hair shaping.

  From US Pat. No. 6,057,056, a hair curler is known which comprises a reservoir, an evaporation chamber, and a compartment for dispensing steam, which compartment comprises both a baffle and an orifice for the steam outlet. This device has the advantage of being small. A baffle is introduced to prevent water flow from passing directly through the hole while allowing steam to pass through, so that no matter what position the device is placed by the user, water leakage It will be gone. Nevertheless, this device does not allow for optimum safety, i.e. it does not prevent water droplets from falling onto the hair and causing it to burn.

  Also known from Patent Document 2 is a steam curling iron for water vapors: a main evaporation chamber equipped with a reservoir, a chamber with baffles and a steam outlet leading to the hair. However, the baffle is placed at the inlet to the fluid and the evaporation chamber is located just above the vapor outlet hole. The baffle must therefore be heated sufficiently so that the evaporation chamber does not cause any water droplet jets to occur on the hair through the exit orifice. In addition, heating at high temperatures is accompanied by undesirable boiling problems in the equipment, which can result in the discharge of hot water droplets on the hair.

  Patent Document 3 is provided with a flat plate including a reservoir having a cosmetic agent and a transport means (felt) by capillary action to a heating chamber including an evaporation plate for allowing vapor to pass over a heated smoothing plate. A steam smoother is disclosed. It is this felt that prevents boiling water droplets from turning into unwanted jets on the hair, but this part has a short life span and is clogged quickly and cannot ensure a continuous flow. Furthermore, no steam can be produced when the felt is dry.

  U.S. Patent No. 6,057,059 discloses a steam smoother with a chamber for generating steam that is placed below the smoothing plate and is in fluid communication with the two lines of steam outlet orifices on either side of the smoothing plate. There is a risk that a drop of boiling water from the chamber can become a jet over the hair.

  Finally, U.S. Pat. Nos. 5,099,086 and 6,037,697 in the name of the Applicant have an evaporation chamber uniquely equipped with two paths in a line-symmetric maze that come together in a common vapor distribution chamber. A steam smoother gun provided is disclosed. On the other hand, if the device does not drop boiling water droplets that can be converted into steam from the chamber onto the hair, this results in very weak steam flow and limited lifetime.

U.S. Pat. No. 3,934,597 U.S. Pat. No. 3,911,648 WO04002263 pamphlet European Patent No. 1652445 French Patent Application Publication No. 2921804 French Patent Application Publication No. 2921803 European Patent No. 0619087 EP 2152114 specification International Publication No. 2008291722 Pamphlet

  The object of the present invention is to solve at least in part the inconveniences mentioned above, while cutting off the anticipated supplementary supply of heat and / or supplementary mechanical tensile forces and / or chemical components. It is to propose a hair treatment device that facilitates the rapid transfer of controlled humidity to the treated hair in an efficient and uniform manner.

  Another object of the present invention is a steam hair treatment device that can be used efficiently in multiple hair styling processes, has excellent resistance to scale and operates in a safe manner.

  Another object of the present invention is a steam hair treatment device that makes it possible to produce a considerable amount of evaporated water.

  Another object of the present invention is a steam hair treatment device that operates reliably, is easy to avoid condensation phenomena, and can be implemented in a simple and economical manner.

  Another object of the present invention is to provide a steam hair treatment with a simplified miniaturized structure that has a continuous flow that facilitates the supply of steam to the hair in a uniform manner, while being able to be industrialized at low cost. Equipment.

  Another object of the present invention is a hair treatment device that is spatially simple and practical to use because the device is manipulated in all directions by the user while allowing for quick and efficient treatment of the hair.

  These objectives are achieved using a steam hair device for styling hair, the steam hair device comprising a first jaw and a second jaw disposed facing each other, wherein A first jaw carried by a first jaw, a second treatment surface carried by a second jaw, the surface intended to grip a lock of hair Evaporating comprising a head and a second jaw, a reservoir of liquid, means for evaporating the liquid in fluid communication with the reservoir, and one or more orifices for distributing vapor in the direction of the hair tress Means for distributing the vapor in communication with the means, the evaporation means comprising a first evaporation chamber forming a unique volume and a second evaporation chamber equipped with a baffle, wherein the chambers Are in fluid communication.

  Thus, vapor formation takes place in at least two different chambers, thereby making it possible to effectively retain unwanted deposits and improve the resistance to scale during the lifetime of the equipment. The first chamber occupies a first unique volume, i.e. a defined volume with no discontinuities or obstacles or barriers. The second chamber occupies a second volume that includes a discontinuity introduced by the presence of baffles to create a labyrinth-type change route for steam. This provides excellent resistance to scale formation. This also makes it possible to evaporate expected water droplets that have not yet evaporated, ensuring the evaporation of all fluids by means of a numerically optimized exchange surface (enlarged surface).

  The baffle means creates an uneven movement of the vapor, i.e. a zigzag movement, e.g. reduces the speed through the chamber, increases contact with the various wall surfaces of the chamber, any obstruction placed in the chamber Or it means a barrier. Because of this baffle, the steam zigzag moves along the horizontal and vertical axes, and can actually create a left-to-right and top-to-bottom zigzag. This also makes it possible to evaporate potential un-evaporated water droplets and ensure that all fluids are evaporated thanks to the optimized arrangement of the exchange surface, i.e. the three-dimensional arrangement of the baffles To do.

  By evaporation chamber is meant any chamber that is heated by any anticipated means of heating, for example an electrical or ceramic resistor called a positive temperature coefficient (PTC) resistor.

  According to the invention, the first evaporation chamber is arranged upstream from the second chamber with respect to the vapor passage. Thus, it can be considered that the “steam creation” function is mainly performed in the first chamber and the “anti-scale” function is mainly performed in the second chamber.

  According to the invention, the internal volume V1 of the first chamber is larger than the internal volume V2 of the second chamber, i.e. at least twice as large as the internal volume V2 of the second chamber. The increased volume V1 allows for quick evaporation, the smaller volume V2 allows to have the required compactness, and the ratio between the two volumes allows for good scale capture functionality. .

  According to the present invention, the baffles or barriers may be divided so as to be parallel to each other. This allows the steam to pass according to a fixed geometry, whereby scale is trapped in a uniform manner in the second chamber.

  According to the invention, the number of baffles may be at least three, even four or five. This allows the steam path to be interrupted while maintaining a relatively small size of the chamber.

  In accordance with the present invention, the first chamber can have a unique volume that is essentially a parallelepiped with a cross-section selected from one of a rectangular cross-section, a square cross-section, a trapezoidal cross-section, and the like. . By “unique” volume is meant the fact that the chamber occupies the volume without obstruction, no baffles, no barriers or bypass elements. This allows a good compromise between the small size and efficiency of the evaporation system.

  According to the invention, the distribution means may be transverse to the evaporation means and preferably extend over most of the entire length of the evaporation means. This makes it possible to make a good compromise between the small size and efficiency of the evaporation system.

According to the invention, alternatively or additionally:
The first evaporation chamber can have a water inlet in the form of a water supply pipe arranged essentially in the center of the first chamber;
The first evaporation chamber may have a water inlet in the form of a water supply pipe having an opening arranged essentially one quarter of the length of the first chamber;
The first evaporation chamber is made of a material containing or coated with PTFE (polytetrafluoroethylene), known under the trade name “Teflon”, or is less likely to adhere to scale; Alternatively, it can have a water inlet in the form of a tube made from another material that does not stick.

  These measures allow an optimized water supply to be placed as far away from the wall as possible in the chamber where the temperature is maximum, thus allowing improved evaporation. The inlet is optimized by the PTFE material type or its equivalent material that makes it possible to suppress scale buildup.

This also makes it possible to suppress undesirable heating effects. Formally, heating is referred to as a liquid adiabatic phenomenon associated with a heated surface that has reached a temperature threshold T _S that is greater than the liquid boiling temperature T _b . This phenomenon is due to the formation of a layer of vapor between the heated surface and the liquid, causing the heat transfer to be quite slow. Heating is observed when water drops fall on a hot plate. Water droplets appear to roll on the surface and do not evaporate immediately.

  According to the invention, at least one heating element can be dedicated to the evaporation means. This allows evaporation, which can be controlled in a manner independent of any other heater in the hairdressing device.

  The heating element may be placed against the largest external surface of the evaporation means and may preferably be placed on the opposite side of the dispensing orifice.

  Alternatively, if the device is composed of two heating elements, these are arranged laterally against both sides of the evaporation means.

  The heating element extends and is placed at least partly against the lateral surface of the evaporation means. Advantageously, one of the two heating elements is placed between the outer lateral surface of the evaporation chamber and the outer surface of the vapor distribution means (distribution chamber), thus evaporating the heat within a reduced size. It is possible to add to the means and the dispensing means simultaneously.

  According to the present invention, the intention can be to adjust the heating element (s) using a thermistor. This thermistor functions as a temperature probe. The thermistor may be NTC (negative temperature coefficient). The thermistor is branched to act as a preventive measure because it can block the means of water distribution (pump) depending on the temperature. For example, other conditions such as stopping the pump and detecting the opening of the smoother can be added. About 95 ° C is considered the lower limit temperature and 130 ° C is the upper limit temperature, or in practice a narrower range from 105 ° C to 120 ° C, ie a value equal to 110 ° C.

  According to the invention, at least part of the internal surface of the evaporation means has a granular coating and / or is at least partially coated with an anti-boiling agent. The anti-boiling agent may be one of silicate, TATE, LUDOX, XYLAN and the like. The anti-boiling agent is preferably applied to the wall of the first chamber, but may be applied to the wall of the second chamber. Application is performed by evaporation or a brush. The granular surface condition allows the fluid to “stick”. These elements alone or in combination make it possible to suppress the undesirable effects of boiling.

  According to the present invention, the two hair treatment surfaces are essentially complementary and are flat, curved or corrugated. Relevant here are Smoother, Carla and Weber, respectively.

The present invention will be better understood upon review of the embodiments, i.e., non-limiting and shown herein.

The base includes a desalting means 2000 that makes it possible to reduce the scale content of the fluid introduced into the base. This desalting means 2000 is placed between the intermediate reservoir that received “all” fluid and the main reservoir 19 that contains the “purified” fluid intended for the hairdressing device 100.

  The first hair treatment surface 4 and the second hair treatment surface 5 are complementary to a device for smoothing (not shown), a device for curling or waving (not shown) or a device for crimping, A flat or curved surface. For example, a curling device is described in Patent Document 7 or described in Patent Document 8 cited as an example. The curling device relates to a device that is preferably used manually for treatment and / or styling hair, preferably a gripping means arranged from the main body and its longitudinal axis on the main body A wrapping body for a lock of hair, mounted for free rotation about, and at least one set of movable jaw clamps for gripping the lock of hair on the body. The crimping device is, for example, a device equipped with two jaws facing each other, each having a non-flat treatment surface as described in US Pat.

  As shown in FIGS. 3, 4, 5, 6, and 7, the first evaporation chamber 71 is disposed upstream from the second chamber 72 with respect to the vapor passage. The internal volume (V1) of the first chamber 71 is larger than the internal volume (V2) of the second chamber 72, that is, at least twice the internal volume (V2) of the second chamber 72. The baffles 73 are distributed in parallel with each other. The illustrated second chamber 72 includes three baffles 73. The first chamber 71 is essentially parallel with a rectangular cross-section as illustrated in the first embodiment and a cross-section selected from one of the trapezoids as illustrated in the second embodiment of FIG. The volume is a hexahedron.

  The distribution means 7 "is arranged transversely to the evaporation means 7 and preferably extends over essentially the entire length of the evaporation means 7. The first chamber 71 has a water inlet in the form of a water supply pipe 74. The orifice is positioned generally in the center of the first chamber 71 and is shown essentially in the middle with respect to its width and essentially within a quarter of the length of the first chamber 71. The first evaporation chamber 71 has a water inlet in the form of a tube made of PTFE material, and at least one heating element 8 is dedicated to the evaporation means 7. The first embodiment is an evaporation means. The second embodiment provides two heating elements, the heating element 8 being in contact with the largest external surface of the evaporation means 7 in the first embodiment. Disposed, preferably on the opposite side of the dispensing orifice 75. The two heating elements 8 of the second embodiment are arranged laterally against both sides of the evaporation means 7.

Flat, curved or corrugated shape.

  The chamber may be made of aluminum and arranged as two parts with two covers, ie the first part shown in FIGS. 3 and 5 is placed on the second part shown in FIGS. , Sealed by silicone fittings. This first part includes a vapor distribution orifice 75 and the second part is placed against the heating element 8. The proper performance of the heating element and thus its optimum operation is effected, for example, by a leaf spring. A temperature sensor 10 may preferably be arranged above the water inlet. The heating element may be a PCT or a ceramic thermistor.

  The liquid reservoir may be incorporated within the smoother that constitutes the device, or alternatively may be located at a distance from the smoother within the expanded base shown in FIG. When placed at a distance, the liquid reservoir is contained in a separate bottle from the smoother-curler device and can be in liquid communication with the vaporizing means of the device.

  The parts where evaporation is effective are the evaporation means and the vapor distribution means. The evaporation means is divided into two separate parts. The first chamber 71 is primarily the evaporation zone 10 itself and is in this space where water is mainly converted into water vapor. The second evaporation chamber 72 is made from a set of baffles 73, which prevents any water droplets from following a direct route toward the evaporation holes 75 of the vapor distribution chamber 7 '. This ensures a uniform vapor quality.

  The body of the evaporation means can be implemented by extrusion. At this time, in order to ensure the tightness of the chamber, it is sufficient to duplicate the main body in accordance with the insertion of the evaporation holes and the respective parts. These end plugs can be made by aluminum casting. Airtightness between these parts can be achieved with the help of silicone joints.

  As shown in FIG. 8, the portable unit 100 includes a heating means 41 for heating the first processing surface 4. The portable unit 100 can include a heating element 41, which can be a PTC or ceramic thermistor placed against the processing surface 4 or disposed inside an element comprising the processing surface 4. The fluid evaporation means 7 includes an evaporation chamber 7 'and a heating element 8 of the evaporation chamber 7'. The chamber (s) are made of aluminum and can include a vapor distribution orifice 7 "and can be placed in direct or indirect contact with the heating element 8. The proper performance of the heating element 8, and thus Its optimal operation is carried out, for example, using a leaf spring, and the temperature sensor 10 can preferably be arranged above the water inlet 21.

  The heating element 8 of the evaporation chamber can be at least one heating element, which can be a PTC or a ceramic thermistor placed against one of the walls or placed inside the element forming the treatment surface. These may be the same as or separate from the heating means of the treated surface. The steam distribution means (7 ', 7 ") are arranged in a direction transverse to the first processing surface 4 and preferably slightly retracted from the processing surface 4 for a series of steam outlets (series, series). ) Or alternatively, the vapor distribution means (7 ', 7 ") has a series of orifices disposed on the processing surface.

  A second embodiment consists in using two heating elements and is shown in FIG. According to this embodiment, the evaporation means (two evaporation chambers) are sufficient to evaporate the water in a sequence of 10 seconds duration and 10 seconds of stop with a flow of about 2.5 g / min ± 1 g / min. It has a maximum external volume of 110 × 35 × 12.5 mm, incorporating a heating system, and an internal volume sufficient to store scale contained in at least 35 liters of hard water having a hardness of 28 ° F. This takes into account these dimensional constraints. Three points still inhibit the buildup of scale in the water inlet tube in a small evaporation chamber. The first is the nature of the tube material at the point of contact between the chamber and the PTFE tube for passing water through the evaporation chamber. On the one hand, this material has excellent performance at temperatures (above 300 ° C.) and has a very low coefficient of friction. On the other hand, this material does not facilitate the accumulation of scale on the walls. The second is the diameter of the water supply section of the tube. The inner section of this tube must be sized to avoid any premature clogging. The inner section must be at least 4 mm in diameter. In order to suppress the transfer of heat from the walls of the evaporation chamber to the water, the tube must have a thickness of at least 1 mm. In addition, a seal made of PPS (polyphenylene sulfide), 6 mm for the inner section and 7 mm for the outer section, must be applied around the tube, thereby heat to the inner wall of the water inlet tube. Transmission is suppressed more than that. The third point is the minimum distance between the outer section of the water tube and the inner wall of the evaporation chamber.

This distance is fixed to 1 mm as an empirical value. This distance makes it possible to suppress the build-up of scale on the outlet section of the tube and thus its premature clogging. Due to the fact that premature clogging is suppressed, an evaporation chamber height of at least equal to 8 mm is required. The two evaporation chambers have, for example, the following measurements: a length of about 107 mm, a width of about 34 mm, a maximum height of about 12.5 mm and a minimum height of about 8.5 mm. The internal width of the first chamber is 16.5 mm, the width of the distribution chamber is 3.5 mm, and the width of the compartment provided to receive the heating element is 35 mm. The water supply pipe passes through the interior of the 20 mm chamber. With the quoted dimensions, the calculated volume of this “evaporation” zone is approximately 14 cm ³ . The height of the evaporation means is maximized so as to make it possible to perform the functions described above. Therefore, it is still possible to place a large cross-section PTFE14 tube at least 1 mm from the upper and lower walls of the first evaporation chamber. A PPS washer is added at the entrance of the evaporation zone. In order to ensure a maximum height in the evaporation zone, it is necessary to place the heating element vertically along the edge. A ceramic or PTC type heating element (preferably for cost reasons) by obtaining the reduced geometry required for maximum reduction of the external volume of this chamber and its low height (12.5 mm) The width of is limited. If there is only a single heating element (PTC1), the exchange surface between the heating element and the evaporation zone (1) is too weak to ensure the desired flow. Another heating element (PTC2) is incorporated to increase the heat capacity of the chamber and to ensure evaporation of this stream. For information, the selected PTCs are PTC1 with dimensions 3.5 × 10.2 × 96 mm and Tmax 225 ° C. and PTC2 with dimensions 3 × 6.5 × 74 mm and Tmax 285 ° C.

Operational Description When operable, when the instrument is turned on, the heating element begins to heat the chamber, and another heating element begins to heat the surface intended to contact the hair.

  When the temperature sensor reaches a temperature threshold (eg 150 ° C.), it causes water to be released by the action of the pump 6 operated by the motor 6 ′. Water arrives at the first chamber equipped with anti-boiling agent and a specific surface finish and falls into it by a supply pipe made of PTFE (so that scale does not stick). The water must fall on the highest temperature surface to make direct contact with the heating element. Water is converted into steam, and the generated steam passes into the second evaporation chamber, passes through the baffle, and arrives in a third chamber (distribution means) equipped with a steam distribution orifice. During the entire life of the equipment, scale builds up depending on the hardness of the water used. This scale continues to be trapped in the evaporation chamber, i.e. first in the first chamber and then in the second chamber by the baffle if the scale is not trapped in the first chamber. Scale is never released on the user's hair. In the test, the steam flow found is on the order of 3 and 4 g / min, closer to 3.5 g / min. However, the pump also ensures relative continuity as well as a relatively constant flow on the order of 1 to 5 mL / min, ie between 3 and 4, preferably equal to 3.5 mL / min.

Advantages of the Invention The present invention provides a number of advantages, among these advantages, among others:
-Make it easier to quickly convey controlled humidity for the treated hair in an efficient and uniform manner, while cutting off the anticipated additional heat and / or mechanical tension and / or chemical input;
-Can be used efficiently during multiple hair styling processes;

Modifications are still possible, i.e. from the point of view of the structure of the various elements or by substituting equivalent techniques without leaving the scope of protection of the present invention.
