Definitions

the invention relates to a hair treatment device according to the preamble of claim 1.
a hair treatment device which consists of hair curlers and a device having a plurality of heating pins for heating the hair curlers.
each hair curler according to this prior publication being a bimetal Contains locking element that fixes it on the heating mandrel of the heating device until it has reached a predetermined target temperature, which corresponds to the optimal hair styling temperature. When this set temperature is exceeded, the bimetal lock releases and the curler is lifted from the heating mandrel by a pre-tensioned spring.
a hair treatment device has already become known from US Pat. No. 4,109,667, in which the temperature dependence of the attraction force of a magnet on a ferromagnetic material arranged in the hair curler with a corresponding Curie point has been used to limit the heating of the hair curlers, but this had to be known Every hair curler used must be equipped with an electric heater, which then had to be connected to a power source in a heating station via touch contacts, and therefore overall, this device required so much cost to manufacture that it was not competitive with other known solutions. In addition, their functional reliability could be severely impaired in the long run by mechanical wear and aging of the electrical connection contacts.
the heating device should be as small and handy as possible and still effective in terms of its heating effect.
it should be possible to heat curlers of different calibers, such as those used to produce large and small curls, on the same heating mandrel without any problems.
a hair treatment device is proposed according to the present invention, which has the features specified in the characterizing part of patent claim 1 within the scope of the device concept outlined at the outset and which can advantageously be designed or operated in accordance with the subclaims.
the holding means which fix the hair curlers on the heating mandrels until their desired temperature is reached consist of a magnet and a body arranged in or on each hair curler and which can be brought into the holding distance of this magnet by plugging a hair curler onto a heating mandrel ferromagnetic material whose Curie temperature corresponds to the set temperature of the hair roller speaks.
the present invention provides a very inexpensive hair treatment device , in which hair curlers can always be heated up in an elegant way, precisely and reliably, to the same specified target temperature.
the magnet has proven to be particularly advantageous to arrange the magnet on the free end of the heating mandrel and the magnetizable body on the corresponding end of the hair curler, so that these two interacting parts are directly adjacent when the hair curler is plugged onto the heating mandrel.
This central placement of the holding means offers significant manufacturing and assembly advantages and also has a particularly reliable effect that the magnetic attraction force, which decreases due to the heating of the ferromagnetic body, reproducibly falls below the counteracting force of the tensioned spring and consequently triggers the lifting of the hair roller from the heating mandrel when the heat-storing core of the hair curler is evenly heated to the specified target temperature.
the effect of the magnet can be improved in a manner known per se by providing it with a so-called iron yoke.
the spring effecting the spring lifting the curler from the heating mandrel by pushing apart the ferromagnetic body and the magnet arranged in the hair curler is preferably supported on the one hand at the lower end of the heating mandrel or on part of the housing carrying it and on the other hand at the lower end of the respective plugged-on heating mandrel Curlers.
it can also be arranged directly between the magnet and the ferromagnetic body, in such a way that the magnet fastened at its lower end - opposite the ferromagnetic body - is fastened via it to the hair curler and when the Hair curler on the heating mandrel comes to the plant.
the present invention can be expediently embodied in that the hair treatment device includes differently heatable hair curlers, for example of the same caliber, which are separate Distinguish by the Curie temperature of the ferromagnetic bodies contained in them and can be distinguished externally, for example by their coloring.
the heating mandrels are preferably heated by means of electrically operated PTC resistors which, due to their known temperature-dependent resistance characteristics, limit the heating of the heating mandrels in a self-regulating manner, so that no additional temperature control is required.
a heating element is arranged underneath each heating mandrel, in such a way that its upper surface rests firmly against the entire surface in a heat-conducting manner directly at the foot of the heating mandrel and is resiliently supported on its underside to intercept its thermal expansion.
conical heating mandrels contain corresponding elongated recesses which are arranged coaxially to the longitudinal axis of the mandrels and in which correspondingly shaped heating elements are positively fixed under a press fit.
the heating mandrels can also be heated with the aid of heating elements which contain devices for thermostatically controlled catalytic combustion of a combustible gas.
the hair treatment device according to the invention can be used completely independently, so that it can be used without any problems, in particular when traveling and in places without a mains voltage connection, and moreover it completely avoids the residual risk, which in principle cannot be entirely ruled out in the case of mains voltage-operated electrical appliances, in the event of improper handling in wet rooms.
An embodiment of the present invention which is distinguished by particular advantages in use, is characterized in that the heating elements and their regulation are set up in this way - ie built and adjusted - and dimensioned so that they continuously heat the mandrels to a temperature that is at least 100 ° Celsius above the target temperature of the hair curlers. This ensures that the heating pins are not only preheated when the hair curlers are plugged on, but are very significantly overheated in relation to their target temperature, so that the hair curlers heat up in the shortest possible time, ie within a few seconds.
This embodiment can be modified to the advantage that it only contains a single heating mandrel; because it has been shown that due to the extremely short heating-up time of the hair curlers achieved by the excess temperature, even with rapid operation, it is readily able to bring one hair roller after another to its desired temperature sufficiently quickly. This also results in significant savings in the manufacturing costs of the heating unit, as well as small device dimensions and low weight.
the heating mandrel In order to avoid energy losses due to heat radiation and convection, it is additionally proposed to laterally enclose the heating mandrel at a distance from a heat-insulating and / or heat-reflecting wall that enables the curlers to be attached. At the same time, this measure prevents burns due to accidental contact with the overheated heating mandrel.
the end In order to prevent burns on the free end of the heating mandrel, the end preferably has a touch guard in the form of a heat-insulating, heat-resistant cap or plate.
the curler 1 can be seen in Figure 1, which contains the body 3 made of ferromagnetic material in the region of its upper end and which has been pushed onto the heating mandrel 2 by gently depressing it against the force of the elastic spring 5, so that it is pushed through the force exerted by the magnet 4 arranged in the free end face of the heating mandrel 2 on the ferromagnetic body 3 is held in this position.
the heating mandrel 2 with the heating element 6 arranged on its foot is fixedly arranged in the interior of a housing 7 by means of construction elements (not shown in the drawing).
a housing 7 by means of construction elements (not shown in the drawing).
Parts 7.1 of the housing wall which enclose the heating mandrel at a distance that allows the curlers to be plugged on, are designed to be heat-insulating and / or heat-reflecting and thereby limit heat losses due to radiation and convection.
the housing surrounding the heating mandrel 2, together with the protective cap 2.1 attached to the end of the heating mandrel prevents a user of the device according to the invention from being burned by accidental contact with the heated mandrel.
Figure 3 shows the embodiment of the present invention according to claim 4, in which the magnet 4 and the compressible lifting spring 5 are components of the curler 1.
the heating mandrel or the heating mandrels are continuously heated to a temperature which is significantly higher than the temperature during the entire period of use of the device
the target temperature of the curlers is.
substantially above the target temperature of the hair curlers means temperatures which are at least above the hair damage temperature and for this reason are usually not taken into account for heating hair curlers.
the permanent temperature of the heating mandrels used in the proposed procedure is preferably at least 100 ° Celsius above the target temperature of the hair curlers, for example 300 ° Celsius.
