Definitions

  • Electric hair dryers delivering an air flow are essential accessories in hairdressing salons: they not only allow professionals to dry outright wet hair after shampooing, but also, to stylists, to highlight forms the hairstyle and create the curls and waves that they desire.
  • the hair can only be styled from of a certain temperature. It should be kept in shape until it cools, which delays the completion of the hairstyle.
  • Conventional hair dryers can deliver air cold by cutting the electrical supply to the heating resistor, but, at because of the thermal inertia of the assembly, the switching between hot air and cold air is not instant.
  • the modification consists in adding to the back of the device a second nozzle delivering cold air in the same direction, but in an opposite direction. Cold air is taken directly from the fan internal. A rotary seal allows to activate or close this second nozzle. When said second nozzle is active, a simple movement of the hand is enough to apply either hot air or cold air by turning the hair dryer held by the handle.
  • the heating part and the outlet nozzle of the device conforming to DE-U-9100860 are shared in two by a partition middle, two separately switchable heating elements being mounted each side of said partition.
  • this apparatus therefore delivers a flow of hot air and a flow of cold air which are collateral; the hot air flow is located either to the right or to the left of the handle plane, depending on that either resistor is switched.
  • the cold air flow can never be located below the hot air flow, first to avoid burning the scalp, when the device is held normally in hand, and then and above all to immediately cool the hair that comes to be heated, because, on the one hand, the two flows of hot air and cold air are collateral and, on the other hand, it is impossible that the nozzle of the device can rotate around its axis.
  • Document FR-A-1387334 also describes a hair dryer having two hot air and cold air ducts, these two conduits being concentric and surrounding a single heating element. So the fluxes produced by this device remain concentric - the hot flux being at center - and therefore they are wide sections and not laminar.
  • the present invention relates to an air hair dryer simultaneous hot and cold air.
  • this hair dryer has a housing of the general shape of a surface of revolution about an axis longitudinal, having a front part and a rear part.
  • a motor electric is mounted inside the rear part of the box and drives a fan.
  • This fan produces a flow of air from back to front, drawn in by a air inlet provided through the wall of the housing.
  • a first conduit channels a first part of the air flow, while a second duct surrounding said first conduit channels the second part of the flow.
  • an electrical resistance heats the first part of the air flow.
  • a handle integral with the housing, is provided with engine speed and power control buttons electric consumed by the resistor from an electrical energy source outside.
  • a first nozzle provided in the extension of the first conduit, delivers hot air and a second nozzle provided as an extension of the second duct delivers cold air.
  • the subject of the invention is precisely a hair dryer. of this type, known in particular from document FR-A-1,387,334, hair dryer the essential feature is that the first and second nozzles deliver simultaneously, a hot air knife and a cold air knife, respectively parallel to the same direction and in the same direction.
  • first and second nozzles are adjacent, their wall common being parallel to the long sides of the hot and cold air knives delivered and being located substantially in a radial plane of the housing.
  • the first nozzle delivering the hot air blade is shorter than the second nozzle delivering the cold air knife and that the plane of the outlet opening of said second nozzle be inclined with respect to a plane perpendicular to the common direction of air flow, the angle of this inclination being preferably between 30 ° and 45 °.
  • the first and second nozzles can advantageously be constituted by a single nozzle with double conduit and double orifice. This single nozzle is then fitted onto the front part of the housing, while being held fixed in translation longitudinally and free in rotation around said front part of the housing.
  • the double duct advantageously has an inlet, corresponding to the duct of shortest outlet, circular section.
  • the first conduit is then a tube whose the front part also has a circular section.
  • the front part of this tube is engaged in this entry while remaining free to rotate.
  • the rear part of the tube is held substantially at center of the base of the front part of the case by at least three ribs longitudinal.
  • each of the outlet ports of the single nozzle is rectangular, preferably approximately ten times longer than wide.
  • the single nozzle is preferably kept fixed in translation longitudinally by means of at least two clips cooperating with a groove annular cut in the front part of the case.
  • the section of the first duct channeling the part of the air flow to be heated can advantageously be substantially equal, or even slightly greater, than that of the second duct channeling the other part of the air flow whose temperature is not modified.
  • the simultaneous hot air and cold air hair dryer according to the invention is very advantageously used for the implementation of a drying process consisting in projecting a flow onto the object or material to be dried of laminar air having a transverse temperature gradient, the part la the colder the flow being kept the closer to the surface of the object or the material by rotating the single nozzle of the device.
  • Figure 1 shows, right view, the structure General of the simultaneous hot air and cold air hair dryer in accordance with the invention.
  • Figure 2 is a section along a median plane A-A showing the internal structure of the hot air and cold air hair dryer simultaneous according to the invention.
  • Figures 3a and 3b are respectively a view of side and a rear view of the single nozzle with double orifice according to a advantageous feature of the hot air and cold air hair dryer simultaneous according to the invention.
  • the general shape of the housing (1) of the hair dryer is that of a surface of revolution around a longitudinal axis (XX ').
  • the part front (2) of this housing has the general shape of a small aperture truncated cone, with an average diameter greater than the current dimension of a device of the same category.
  • This front part (2) is attached to a rear part (3) of which the general, traditional appearance is that of a cylinder which would be swollen in its middle part, or a small barrel.
  • this part is, still in the traditional way, itself made up of two half-shells fitting one inside the other.
  • An electric motor (4) is mounted inside the rear part (3) of the housing (1). It is a motor running on current 220-240 V AC and having a power of one hundred watts. This engine (4) drives a fan (5) of centrifugal type (both shown in dotted on Figure 1), which produces an air flow (6) from back to front at inside the housing (1).
  • the air is sucked in through an air inlet (7) provided at the through the rear wall of the housing (1).
  • This air inlet fitted with a grid, is also an insert on the rear part (3).
  • a first conduit (8) having the general shape of a frustoconical opening substantially equal to that forming the front part (2), channels a first part (9) of the air flow (6) produced by the fan (5).
  • resistance electric (12), wound on crosses, is inside the first conduit (8). With an electrical power between 1500 W and 1700 W, it heats the part (9) of the air flow circulating in the first duct (8).
  • a handle (13) attached to the rear part (3) of the hair dryer allows easy use of it.
  • This handle is presented in the form of two half-shells joined by screws. Traditionally, these two half-shells are in fact advantageously the extensions of the two half-shells constituting the rear part (3) of the device.
  • the handle (13) carries two buttons (14, 15) of ordered.
  • One (14) sets the speed of the electric motor (4): as required, the fan (5) can be stopped or maintained at a medium speed or maximum.
  • the other button (15) switches the electrical power consumed by the heating resistor (12) between a zero, average value and maximum.
  • the handle (13) is provided with a grommet intended for hold the AC power cord (16).
  • a first nozzle (17) with a narrow outlet orifice and elongated is in the extension of the first conduit (8) containing the heating resistor (12), and it consequently delivers a blade of hot air (18).
  • a second nozzle (19), the outlet opening of which is also narrow and elongated, collects the cold air flow (11) circulating between the internal wall of the front part (2) of the device and the duct (8) channeling the hot air, to eject it in the form a blade of cold air (20) in the same direction (XX ') and in the same direction as the hot air blade (18).
  • the section of the first conduit (8) is substantially equal to or even slightly higher than that of the second conduit (10) so that the flow of hot air produced by the device according to the invention is equal to, or according to, slightly higher than the cold air flow.
  • the nozzles (17, 19) have a complex shape.
  • the set looks like two tips flat, classic, which would have been nested laterally one inside the other, a lower side part of the nozzle intended to blow cold air having been deleted.
  • a lateral part of the nozzle blowing hot air then constitutes the common wall (21) of the two nozzles (17, 19).
  • the two nozzles are arranged such that this common wall (21) corresponds to a radial plane (BB) of the housing (1).
  • the first nozzle (17) delivering the hot air blade is shorter than the second nozzle (19) delivering the blade of cold air, the difference length (E) being substantially 1 cm in this preferred embodiment.
  • the plane (CC) of the outlet orifice (22) of the second nozzle (19) has an angle of inclination ( ⁇ ) relative to a plane perpendicular to the longitudinal axis thereof.
  • This angle of inclination ( ⁇ ) is around 35 ° for this particular embodiment of the nozzle (19).
  • the length difference (E) between the two nozzles (17, 19) and the bevel size of the nozzle (19) delivering the cold air knife depends on the use which will be made of the hair dryer, as will be explained later.
  • the angle of inclination ( ⁇ ) is preferably between 30 ° and 45 °.
  • each of the outlet openings (22, 26) of the single nozzle (23) is rectangular, and about ten times longer than wide.
  • Cold air flows (20) and hot air (18) supplied by the single nozzle (23) are therefore both laminar.
  • This single nozzle (23) can be manually inserted on the front part (2) of the hair dryer. It is held there fixed longitudinally, while being free to rotate. By exerting an effort sufficient, it can however be removed manually to be replaced by when needed.
  • the inlet (27) of the corresponding double conduit (24, 25) the shortest outlet duct (25) is of circular section.
  • Front end (28) of the conical conduit (8) containing the resistor (12) is also of section circular, slightly smaller in diameter than the inlet (27), and is engaged in this entry (27) while remaining free to rotate in the two sense, retrograde and direct.
  • the section (AA) in Figure 2 shows that the part rear (29) of the tubular conduit (8) is held substantially in the center of the base (2 ') of the front part (2) of the housing (1) by longitudinal ribs (30). These ribs have the appropriate width at the back and they narrow towards the front, until it disappears: the front part (28) of the tubular conduit (8) can thus freely debate within the entire section of the front part (2) of the housing (1).
  • This particular arrangement allows the orifices (22, 26) to be oriented, as required, by rotation of the single nozzle (23) around the front part (2) of the hair dryer, while continuing to be supplied with air cold and hot air, respectively.
  • the front part (28) of the duct (8) remains engaged in the circular inlet (27) of the nozzle, so that the conduit (25) opening to the outside through the orifice (26) always blows hot air, and only hot air.
  • the nozzle single (23) is held longitudinally by means of at least two clips (31) cooperating with an annular groove (32) cut in the front part (2), near the end of it.
  • This process is well known in the field of the manufacture of molded plastic articles. He was retained here because he contributes to the ease of use of the device.
  • the hair dryer according to the invention has numerous advantages, in particular due to the shape of the outlet orifices of the nozzles (17, 19) constituting the single nozzle (23), relative positions of these orifices outlet and differences in length (E) of the nozzles (17, 19).
  • the longest nozzle (19), which blows from cold air (20) is placed close to or even against the head, the shortest nozzle (17), which delivers hot air (18), being on the other hand the farthest from the head.
  • the single outlet nozzle (23) is rotated around the part front (2) of the housing (1), in order to respect this arrangement of the nozzles (17, 19).
  • the hair, first shaped and dried by hot air are immediately cooled after the passage of air hot.
  • the hair dryer follows the brush which shapes the hair in a movement, controlled by the hairdresser, going from the base of the hair towards the tip of it; due to this movement imposed on the hair dryer by the hairdresser, the hot air blade is also moved from the base of the hair to dry and shape in the direction of its tip and the blade of cold air follows immediately the blade of hot air in this same movement; so the setting the shape given to the hair by hot air is immediately fixed by cold air.
  • the construction according to the present invention constitutes so a different overall solution to the problem of fast air switching hot / cold air (parallel laminar flow) and the safety problem (avoid spray hot air on the scalp).
  • the construction according to the invention by its structure and the results to which it leads, is clearly distinguished from that described in document DE-U-9100860.
  • the outlet nozzles (17, 19) are adjacent, their walls common (21) being parallel to the long sides of the cold air and hot air blades delivered, whereas according to DE-U-9100860, the adjacent outlet nozzles have a common wall which is perpendicular to the long sides of the two air knives issued.
  • the flows of hot air and cold air do not therefore not follow automatically in the movement controlled by the hairdresser, going from the base to the tip of the hair.
  • the hair dryer in accordance with document FR-A-1.387.334 it is unsuitable for carrying out drying and hair shape for which hot and cold air flows are distributed in laminar and parallel form, the blade of cold air also being always kept as close as possible to the scalp or the surface of the object to be cooled if this object is other than a hair.
