Definitions
- the present invention relates to the technical field of hair dryers and, more particularly, to electric hand-held hairdryers used by professionals and / or private individuals.
- a hand-held hair dryer generally comprises an elongate tubular body which contains a motor-fan unit formed of a propeller integral with the drive shaft of an electric motor.
- the electric motor is held in the tubular body by rigid arms which ensure the centering of the helix relative to the inner wall of the tubular body.
- the tubular body is equipped with a handle comprising a connection cord to the electrical network and control members of the operation of the electric motor.
- the motorcycle fan unit draws air through an inlet located at the rear of the tubular body to push back through an outlet located at the front of the latter.
- the hair dryer also comprises, downstream of the propeller, means for electric heating of the blown air.
- Such a hair dryer gives satisfaction with regard to its primary function of drying hair.
- known hairdryers have the disadvantage of being particularly noisy which induces fatigue during their prolonged use by a professional or a nuisance for the user and those around him.
- This noise nuisance results in particular from the speed of rotation of the engine which is generally between 7000 and 16000 rpm.
- One way to limit noise pollution is to reduce the speed of rotation of the motor.
- the speed of rotation is reduced, it becomes necessary, to maintain a satisfactory air flow, to increase the diameter of the propeller.
- such an increase in the diameter of the helix modifies the proportions of the hair dryer which can be difficult to handle if it has a typical configuration of the pistol type with a handle extending perpendicular to the blowing axis of the hair dryer.
- the increase in the diameter of the helix induces such an increase in the outer diameter of the body of the dryer. hair that it is not possible to hold it by his body with one hand during the making of a hairstyle.
- this measure determines a drying rate according to a precise and repeatable protocol using a fabric ISO 2267:
- the hair dryer is placed in front of a flat surface constituted by the wet tissue.
- a drying index of the fabric is measured by the hair dryer using the weighing of the initially wet fabric and fabric frame after exposure to the operating hair dryer for a predetermined time.
- One of the objectives was to propose a measurement method in the context of a private protocol and which could nevertheless be eligible as a standard.
- the starting point of the invention relates to a hair dryer comprising a tubular body of longitudinal axis ⁇ which is open at a said forward end and which comprises, near a rear end opposite the outlet, an inlet substantially peripheral air, a motor-fan unit which is disposed in the tubular body between the inlet and the outlet and which comprises an electric motor driving in rotation, along an axis parallel to or coincident with the axis ⁇ , a rotor located in a working chamber and adapted to suck air through the inlet and back through the outlet, this hair dryer comprises: at the rear of the tubular body, a central core of axis ⁇ comprising a peripheral surface which is concave and converges towards the working chamber and which delimits, with the body tubular, the air inlet and a ring-shaped suction duct; in the suction duct, at least one annular curved fin of axis ⁇ whose intrados and extrados converge towards the working chamber.
- the implementation of the central core with its concave and converging peripheral surface makes it possible to define an angled suction duct which rectifies the flow of air to the extent that at the outlet the air flow is substantially parallel to the axis ⁇ while at the inlet the air flow forms a non-zero angle with the axis ⁇ .
- the use of the annular fin makes it possible to obtain, in the suction duct, a laminar displacement of the sucked air, which contributes to increasing the performance of the hair dryer by reducing the pressure losses by upstream of the working chamber.
- the implementation of the central core associated with the peripheral air inlet allows to release the rear face of the hair dryer which can then be used to place gripping means or fixing. In the same way, since the suction of the air does not occur at the back of the hair dryer, it is possible to fix the hair dryer to a wall with its rear face close to the wall without risk of deterioration of the performance of the hair dryer.
- the invention relates to a method for measuring the drying efficiency of a hair dryer, a method using a drying frame comprising a vertical sheet of fibers to be dried fixed to less at their upper end on a support and comprising at least:

- This wick size makes it possible to approach the size and the thickness of the locks formed during the passage of the fingers in a long or half-long hair.

- the surface of the web to be dried is greater than 1.5 times the outlet section of the hair dryer, preferably 1.9 times the outlet section of the hair dryer. Such proportions also make it possible to be as close as possible to the drying conditions of an adult's hair.
- the outlet and the front face of the sheet to be dried are displaced relative to each other in a scanning movement.
- This procedure simulates a common use of a hair dryer during which the hot air flow of the latter is moved to avoid burning hair or even the scalp of the person whose hair is dried.
- Various movements can then be envisaged such as for example an alternating rotation of the hair dryer around a vertical or horizontal axis parallel to the front face of the sheet to be dried.
- the scanning movement is an alternating translational movement in a horizontal or vertical direction parallel to the front face of the sheet to be dried.
- the scanning movement is a rotational movement about an axis normal to the front face of the sheet to be dried separate from the blow-molding axis of the hair dryer.
- the test distance is chosen so that the temperature at the center of the air flow from the hairdryer, measured at the test distance of the output of the hair dryer has a value between 60 ° C and 76 ° C.
- This characteristic corresponds to the distance generally used to avoid burning the hair or the scalp.
- the frame to be dried comprises at its rear side at least one mesh or open mesh net limiting the movements towards the rear of the sheet to be dried.
- the measurement of evaporation involves the ratio of the mass of the web to be dried before application of the air flow and the mass of web to be dried after application of the flow of water. during the drying period.
