Definitions
- hair dryers are used in hairdressing, not only for drying the hair but also for carrying out various treatments, essentially for shaping the hair, sometimes with simultaneous use of treating agents.
- Technological background Many variants of hair dryers and the like are known, which are based on the principle of combining at least one heat source, generally in the form of an electrical resistance with a fan, so as to create a flow hot air used to treat hair.
- connection to the network on the one hand is quite annoying in the use of the hair dryer, and on the other hand strongly limits the area of use and considerably reduces freedom of movement.
- the resistance itself is a strong consumer of energy and it is not possible to power it through the battery if you want to limit the weight and size of the hair dryer.
- the present invention is based on the idea of dissociating in the same hair dryer or equivalent the heat storage functions for air heating and electricity storage functions to operate the fan. In this way, a different principle or means is used for each function, which is each time best suited to this function.
- a heat storage element is used, which is directly heated using one or more electric resistors incorporated in this element, and one or more rechargeable electric batteries which are used only to drive the fan motor.
- the invention relates to a device of the hair dryer or similar type, associating an electric heating resistor with a fan in order to create an air flow, characterized in that it comprises a series of electrical contacts via a base, connectable to the network and on which the device can be placed, as well as an electrically rechargeable battery making it possible to supply the motor with a fan 'and a heat accumulator element heatable by an electrical resistance.
- the first group of contacts makes it possible to charge the battery or batteries and a second group of contacts makes it possible to supply one or more electrical resistors separately ensuring the heating of the heat accumulator element.
- the rechargeable direct current batteries are supplied via a rectifier-transformer, and the second group of contacts directly supplies the heating resistors.
- the device includes a safety thermostat to avoid overheating.
- the shape and arrangement of the two contact groups are chosen so that it is not possible to inadvertently make faulty connections by reversing the charge current of the batteries and that supplying the heating resistors.
- the heat storage element may for example be constituted by a ceramic material, preferably of the ⁇ téatite or cordierite type. Other means can in particular be envisaged. With a view to heat storage without going through a heavy and bulky electric battery and of poor performance, one solution consists in ensuring the storage of heat in a refractory mass associated with one or more tanks containing a fusible material.
- the refractory mass generally obtained by extrusion generally consists of steatite and cordierite and may include a multiplicity of longitudinal holes * .
- the intrinsic insulating qualities of the refractory masses generally used allow them to receive a certain number of electrical resistances.
- Another series of passages are left free to circulate a current of air generated by the fan.
- the large surface formed by the internal walls of the holes allows good heat exchange with the air powered by the fan which passes through these passages.
- a solid refractory mass of this type will be brought quickly, in a few minutes, to a high temperature of the order of 150 ° to 200 ° C, these temperatures being limited by an incorporated thermostat.
- This mass is incorporated into the hair dryer and is insulated from the shell by insulating sheets or layers to conserve most of the stored heat energy for a sufficient time and of course to prevent the shell from overheating.
- the air flow passing through the internal channels of the mass will carry the heat which will be distributed towards the hair by the conventional intermediary hair dryers, concentrators, diffusers, etc.
- suitable means are provided so that initially the fan can propel a mixture of ambient air and hot air having passed through the battery of refractory elements.
- a shutter controlled by a device of the bimetal type (bimetallic strip) makes it possible to regulate the temperature of the hot air leaving and in particular to reduce the proportion of fresh air as the temperature of the refractory mass decreases.
- Figure 1 shows a partially cutaway schematic view of a device according to the invention
- Figure 2 shows a rear view similar to that of Figure 1
- FIG. 3 represents a plan view of the arrangement of the electrical contacts on the rear part of the handle of the hair dryer
- FIG. 4 represents a plan view of the arrangement of the electrical contacts in the base 3.
- the device which in this case is of the hair dryer type consists of a housing bearing the general reference 1, which can be deposited by its handle 5 on a base 3 connected to the sector by an electric cord.
- This base has two contacts or pins 7 and two contacts or pins 7 '.
- the contacts 7 ′ are intended to charge, thanks to a rectifier-transformer, rechargeable batteries 9 and 9 ′ arranged inside the handle 5 of the hair dryer 1.
- Complementary contacts 7 and 7 ' are provided on the handle 5 so that, when the hair dryer rests on the base, the necessary supplies are established.
- the two other contacts 7 are used to directly supply electrical current to the resistors (not shown) included in the heat storage element 11.
- a motor 13 driving a fan propeller 15, this motor being supplied with electric current by the batteries 9 and 9 '.
- the constitution of the heat accumulating mass is preferably carried out in the following manner.
- the heat storage element 11 consists on the one hand of a barrel made of steatite or another similar insulating and refractory material 19 provided with bores. In these bores are incorporated cartridges or tubes 17 containing a fusible material in an adequate temperature range such as those mentioned above.
- the melting temperature is chosen so as to be slightly lower than the maximum storage temperature provided for the storage of heat energy, that is to say the temperature setpoint of the thermostat which stops the heating resistance of the together.
- insulating elements, sheets or insulating layers are incorporated between the shell and the refractory mass.
- the contacts 7 and 7 ′ are supplied with electric current, and by separate circuits, the procedure is carried out each time when necessary on the one hand at the low voltage charge of the batteries. 9 and 9 'and also reloading heat of the heat accumulator element there, under the effect of electrical resistances.
- the mass charge and discharge cycle for heat accumulation is as follows.
- the resistance generally of high power which can reach for example 2000 W
- the refractory mass 19 will gradually heat up and it may for example reach in a few minutes a set temperature regulated by the thermostat.
- This supply of heat which diffuses through the refractory mass also causes the fusion of the fusible salts contained in the cartridges 17 which of course consumes energy and slows down the heating of the refractory mass which surrounds the cartridges 17.
- all the mass contained in the cartridges 17 will be liquefied and the temperature will then increase rapidly in the refractory mass, the thermostat then quickly reaching its set temperature and interrupting the power supply.
- the hair dryer When the hair dryer is then removed from its base and is used, i.e. when the engine is running and propelling air through the barrel, this air heats up and is then evacuated and performs the function a normal hair dryer.
- the temperature of the refractory mass will then tend to drop, but the phase modification of the soluble salts contained in the cartridges will have the effect of counteracting this temperature reduction as long as the phase modification takes place at constant temperature and the temperature of the the air coming out of the hair dryer will be practically constant. For example, you can set the thermostat setpoint to around 150 ° C and choose salts with a state change temperature of around 130 ° C.
- thermo-regulating flap can be provided to initially mix a quantity of fresh air with the air circulating in the refractory mass so that the temperature of the air blown out of the hair dryer is not too high and remains substantially constant. However, as the temperature of the refractory mass decreases, this supply of fresh air decreases by the effect of the flap which gradually reduces the amount of fresh air.
- hairstyling frequently involves interruptions. It is sufficient, during each of these interruptions, to place the hair dryer on its base to allow it to accumulate both the electrical energy necessary for the fan motor and the electrical energy necessary to heat the accumulator element. heat.
- Various charge indicators and safety equipment can be provided, in particular at the electrical resistances, to act as a circuit breaker when a critical temperature is reached.
- the base and the removable hair dryer have electrical contacts, for example pins.
- electrical contacts for example pins.
- the base 3 comprises in practice a rectifier-transformer which supplies only the pins 7 connected to the rechargeable batteries while the pins 7 'can be connected directly by the base to the networks and are used to supply the electrical resistances.
- the device which has just been described is of course adaptable to equivalents of the hair dryer such as heated brushes or heated combs which also operate on the principle of an air flow caused by a fan and an element. heating for this air flow.
- the principle described for the hair dryer in the preferred embodiment of the invention is of course transposable to them.
