Abstract:
The invention concerns a method for measuring the drying efficiency of a hairdryer (SC), method implementing a drying frame (100) comprising a vertical web (104) of fibres to be dried, attached at least by the upper ends thereof to a support and comprising at least: a first step of measuring the evaporation of the water contained in the web (104) of the drying frame (100), a front face of the web (104) being subject, for a reference drying time, to the flow of air from the hairdryer whereof the outlet (4) is located at a reference distance (Dd) from the front face of the web (104) and which operates at a reference power, the rear face of the web (104) being located at least 1 metre away from the nearest surface, a second step of measuring the evaporation of the water contained in the web (104) of the drying frame (100), the front face of the web (104) being subject, for a reference drying time, to the flow of air from the hairdryer whereof the outlet (4) is located at the reference distance from the front face (Fa) of the frame (100) and which operates at the reference power, the rear face (Fb) of the web (104) being in substantially tangential contact with a solid (108) of spherical or ovoid shape.
Abstract:
The invention relates to a method of evaluating the noise emitted by a hairdryer of longitudinal axis Δ with a forward outlet, method comprising the following steps: implementation of a dummy human head (T) with two microphones, one placed at the level of the left ear and the other at the level of the right ear of the dummy head on each side of the sagittal plane S, of symmetry of the head, placement of the hairdryer while operating on a rear side of the head with the outlet oriented towards the head (T) and situated a distance (D) from the head lying between 5 cm and 20 cm, the longitudinal axis (Δ) of the hairdryer being included in a vertical plane (V) making an angle a of between 30° and 50° with the sagittal plane S, of symmetry of the head T, and positioning of the longitudinal axis (Δ) of the hairdryer in a horizontal plane (H) passing through the microphones, then measurement of the left and right acoustic pressure by the microphones and calculation of the mean dB1 of these two measurements, positioning of the longitudinal axis (Δ) of the hairdryer with the outlet oriented downwards, in an inclined plane (P) making with the horizontal plane an angle (β) of between 30° and 50°, then measurement of the left and right acoustic pressure by the microphones and calculation of the mean dB2 of these two measurements.
Abstract:
Hairdressing appliance comprising at least: - two jaws, a first jaw (1) and a second jaw (2), which are elongate and hinged together so as to be able to move between an open position and a closed position in which opposing working surfaces define a hair treatment region, and - electric heating means associated with at least one of the working surfaces. According to the invention, the first jaw (1) at least comprises at least one friction bar (10, 31) which is able to move with respect to the adjacent working surface and which is designed to engage with an opposing element of the second jaw (2) so as to define in the closed position of the jaws a traction region which generates, as the appliance is moved over the lock of hair, a traction force greater than the traction force generated by the treatment region.
Abstract:
The invention relates to a handle (1) for a cooking vessel (2), comprising at least one thermoelectric generator (3) thermally connected to a heat sink (4). The invention is characterised in that the handle (1) comprises an inner cavity that extends longitudinally over at least one third of the length of the handle (1), and the heat sink (4) extends longitudinally inside the cavity through at least two thirds of the length thereof.
Abstract:
L'invention concerne un récipient de cuisson (1) comportant une calotte (2) munie d'un fond (3) et d'une paroi latérale (4), une poignée (20) fixée à la calotte (2) par des moyens de fixation (6, 22) et un capteur (30) agencé dans un logement de réception (11) à proximité du fond (3) et muni d'au moins un élément conducteur (31, 32) isolé électriquement, lesdits capteur (30) et élément conducteur (31, 32) étant fixés à un support (40) qui s'étend à partir du fond (3) le long de la paroi latérale (4) et qui est fixé à la poignée (20). Conformément à l'invention, le support (40) comporte une partie de maintien (42) du capteur et de l'élément conducteur et au moins une zone de déformation programmée (50, 55a, 55b) pour permettre une mobilité entre la partie de maintien (42) du capteur et de l'élément conducteur et la poignée (20) suivant au moins une direction.
Abstract:
The invention relates to a hairdryer comprising: a tubular body (2) with a longitudinal axis (Δ), the body being open at a front end, called the outlet (4), and comprising, near a back end (6) opposite the outlet (4), a substantially peripheral air inlet (7); a motor-blower unit (10) that is placed in the tubular body (2) between the inlet (7) and the outlet (4) and that comprises an electric motor (16) driving in rotation, about an axis parallel or coincident with the longitudinal axis (Δ), a rotor (11) located in a working chamber (12) and designed to suck air into the inlet (7) and force it out of the outlet (4). According to the invention, the hairdryer comprises: behind (6) the tubular body (2), a central core (20) with a longitudinal axis (Δ), said core comprising a peripheral area (21) that is concave and converges toward the working chamber (12) and that bounds, with the tubular body (2), the air inlet (7) and an annular suction duct (12); and, in the suction duct (13), at least one curved annular blade with a longitudinal axis (Δ), the pressure surface (24) and the suction surface of said blade converging toward the working chamber (12).
