Definitions
- the invention relates to a device for blowing hot air for drying hair and comprising, in a housing, an electric heating resistor, a fan unit intended to create a current of air between a cold air inlet and a hot air outlet nozzle.
- the invention relates, more particularly, to a device for blowing hot air, the housing of which includes an additional heating means such as a ceramic element capable of emitting infrared radiation of particular wavelength, when it is brought to a certain temperature.
- an additional heating means such as a ceramic element capable of emitting infrared radiation of particular wavelength, when it is brought to a certain temperature.
- Such an additional heating means is, for example, described in European patent application No. 329864. Thanks to this additional heating means, the drying of the hair is improved. Unfortunately, the rise in temperature of the ceramic element being a function of the power of the electric heating resistor used and the heating time, the user does not know if the ceramic element has been brought to a set temperature corresponding to l emission of particular infrared radiation. Therefore, in many hair dryings, in which, for example, the user operates the device according to short heating cycles, the means additional heating with particular infrared radiation is never put into service and the user, without knowing it, therefore dries his hair only with the heating of the electrical resistance.
- the invention therefore aims to eliminate this drawback and thus make the device more efficient.
- the device comprises a device for displaying infrared radiation of particular wavelength.
- the user directly visualizes the operating mode of the device. Therefore, he can wait until the ceramic element has reached its set temperature corresponding to the emission of the particular infrared radiation before using the device to dry his hair.
- the hot air blowing device shown in FIG. 1 comprises, in a housing 1, an electric heating resistor 2, a motor-fan unit 3 intended to create a current of air between an inlet 4 of cold air and a hot air outlet nozzle 5, as well as an additional heating means 6 comprising a ceramic element whose surface is capable of emitting infrared radiation of particular wavelength, when it is brought to a certain temperature. setpoint which can be chosen, for example, in a range from 60 ° C to 120 ° C. Such an element is well known in itself and has been, for example, described in European patent application No. 329864.
- the device comprises a device for displaying infrared radiation of particular wavelength.
- said display device comprises a light diode 7 mounted on the housing 1 and controlled by an infrared sensor equipped with a selective filter and shown diagrammatically at 8.
- This sensor 8 is connected to a comparison amplifier 9, the output signal of which is sent to an interface 10 for controlling the light diode 7.
- the diode lights up warning the user of the operation of the device according to a combined heating mode: electrical resistance and particular infrared radiation, which is well suited to rapid drying of the hair.
- the ceramic element 6 is arranged in the end region of the nozzle 5 for hot air outlet and is shaped as a grid as best seen in the figure 2.
- This grid comprises a series of concentric and radial bars, the external faces 7 of which are coated, at least in the central region of the grid, with a change of state material 11 which reacts to particular infrared radiation.
- a state change material is constituted, for example, by liquid crystals or more economically by a paint which changes color as a function of the temperature generated by the resistor 2 and the ceramic grid 6. This color change occurs beyond a set temperature which is chosen in particular as a function of the set temperature of the ceramic element.
- the external surface of the grid 6 is brought to a temperature T approximately equal to 391 K and according to the law of STEFAN-BOLTZMANN the radiation power P is approximately 1.7, which gives a maximum wavelength of 7.4 ⁇ m (far infrared).
- the paint used in the cold state has a red color and in the hot state, that is to say in this example for a set temperature above 100 ° C., a black color.
- Such a paint is sold, for example, by the company H ⁇ ROTRON GMBH under the reference "HO" - "RES".
- the change in color warns the user that the ceramic grid 6 emits said particular infrared radiation and that the drying is carried out according to the combination of heating resistance and particular infrared.
- the ceramic element consists of a ring 12, while the nozzle 5 for hot air outlet comprises a metal or plastic grid 13 whose central region of the external face is coated with a change of state paint 14.
- the nozzle 5 of hot air outlet being equipped with a grid 15, the central region of this grid carries the ceramic element which is shaped for this purpose into a pellet 16 whose external face is coated with a layer of paint 17 with change of state.
- This layer of paint can also be applied to a self-adhesive patch intended to be bonded to the central outer region of the grid 13.
- the ceramic element is chosen so as to allow the use of a paint which will change color around 60 ° C.
- the user observes the emission of the particular infrared radiation by the punctual color change at the level of the central region of the grid 6, 13 or 15, which makes it possible to obtain a more pronounced display device while preserving the aesthetics and low manufacturing cost due to the small paint surface.
