Definitions
- the invention is based on a wireless curling iron according to the preamble of the main claim.
- a wireless curling iron with a separate heating station is already known from DE-A1-31 37 545, the heating station having a shape for receiving a winding mandrel of the curling iron, into which the winding mandrel can be inserted during the heating process to produce an intimate thermal contact is.
- the temperature of the heating block of the heating station is regulated to a predetermined setpoint by means of an integrated thermostat. In order to prevent the curling iron from overheating during the heating process, the temperature setpoint of the heating block must be identical to the maximum permissible heating temperature of the curling iron.
- Such a temperature setting of the heating block is disadvantageous with regard to the duration of the heating process of the curling iron. It is desirable that the temperature of the heating block for rapid heating of the curling iron would be considerably above the target temperature of the curling iron.
- the curling iron according to the invention has the advantage of a very short heating-up time and a defined and reproducible heating temperature. Due to the short heating-up times, a quick hairstyle is possible, which is not interrupted by longer heating-up breaks.
- the defined and reproducible adjustable heating temperature of the curling iron ensures, on the one hand, that the curling iron is not too high a temperature which could damage the hair and, on the other hand, is not too low a temperature which does not lead to permanent curling of the hair would lead.
- magnetic holding means in the vicinity of at least one of the edge areas of a heating block of the heating station or the winding mandrel of the curling iron. This avoids direct heating of the ferromagnetic body, the Curie temperature of which essentially corresponds to the target temperature of the curling iron. This effect is supported in an advantageous embodiment in that there is no direct thermal contact between a magnet attached to the heating block and the ferromagnetic body. It is thus ensured that the ferromagnetic body essentially assumes the temperature of the winding mandrel of the curling iron.
- An embodiment of the invention has proven to be very advantageous, in which the gravitational force is used as the first force acting counter to the magnetic force. The gravitational force is available "free of charge", so to speak, so that no additional spring or elastic elements have to be used. This configuration enables an inexpensive embodiment of the invention to be implemented.
- the first force is generated by a spring element which is designed either as a spiral spring or as a wire element receiving the winding mandrel of the curling iron.
- Another very advantageous development of the invention consists in attaching several ferromagnetic bodies with different Curie temperatures over the length of the winding mandrel. Different target temperatures of the winding mandrel can then be set by means of the variable immersion depth of the winding mandrel in the heating station, with ferromagnetic bodies having different Curie temperatures depending on the immersion depth the magnet in the heating block. These measures make it possible, for example, to adapt the temperature setpoint of the heating mandrel to different degrees of moisture or hair types.
- Figure la an embodiment of the curling iron according to the invention
- Figure 1c the positioning of the curling iron after the end of the heating process, d. H. after reaching the target temperature
- FIG. 2 shows a further embodiment of the curling iron according to the invention, in which the gravitational force is used as a further force, and
- FIG. 3 shows a third embodiment of the curling iron according to the invention, in which the spring force of a wire element receiving the mandrel of the curling iron is used as a further force.
- FIG. 1 A first exemplary embodiment of an indirectly heated curling iron 10 with a separate heating station 11 is shown in FIG.
- the curling iron 10 is composed in a known manner from a winding mandrel 12 and a handle part 13.
- a protective cap 14 is fastened to the head part of the winding mandrel 12, which is made of a material with low thermal conductivity and therefore does not heat up significantly.
- the winding dome 12 consists of heat-storing material and is wholly or partly interspersed with a magnetic material which changes its magnetic properties as a function of the temperature (eg Thermoflux).
- the winding dome 12 has a ring 15 made of such a magnetic material in its central region. Of course, several such rings 15 can also be arranged on the winding dome 12.
- the at least one ring 15 is preferably arranged in the region of the two ends of the winding mandrel 12.
- the heating station 11 consists of a housing 16 which has a recess for introducing the winding mandrel 12.
- a heating block 18 schematically shown in FIG. 1b, c, with a shape 17, which is heated by means of a resistance heater with a thermostat, a heater with a PTC resistor or the like.
- the invention is not limited to mains powered, i.e. electrical heating stations limited, but can also be used for gas-heated heating stations, for example.
- Accidental contact of the heating block 18 can be avoided by a pivotable grid 19 covering the recess of the housing 16 and the shape 17 or similar protective measures.
- At least one permanent magnet 20 and one spring element 21 are let into the heating block 18.
- the permanent magnet 20 is positioned in the heating block in such a way that it is attached to the winding do 12 of the curling iron 10 Ring 15 is congruent as soon as the winding dome 12 has been properly inserted into the formation 17 of the heating station 11.
- the ring 15 has normal magnetic properties, so that if the poles of the ring 15 and the permanent magnet 20 are suitably arranged, an attractive one Force occurs between the winding dome 12 and the heating block 18.
- the magnetic properties of the material of the ring 15 determine the desired temperature value of the winding mandrel 12 of the curling iron 10. If the temperature of the ring material approaches the Curie temperature, the permeability of the ring material decreases. This leads to a reduction in the magnetic holding forces between the winding dome 12 and the heating block 18, so that finally the influence of the repulsive spring force of the spring element 21 gains the upper hand and lifts the winding dome 12 from the heating block 18 at the end of the heating process.
- the curling iron 10 is now ready for use and can be used for hair shaping for a longer period of time.
- the temperature setpoint of the winding mandrel 12 is determined by a suitable selection of the ring material, preferably in the range between 100 ° C. and 200 ° C., in particular to approximately 150 ° C., while the temperature of the heating block 18 is in particular approximately 100 ° C. - 200 ° C higher. This measure ensures that the curling iron 10 heats up very quickly.
- curling iron 10 has a very simple structure, can be cleaned quickly and without problems and, due to the lack of electrical or mechanically sensitive components, has a very high level of operational reliability.
- FIG. 1 A further embodiment of the invention is shown schematically in FIG.
- the front view of the heating station 11 is shown, in which the winding dome 12 is brought in for heating.
- the heating block 18 is arranged in the upper region of the housing 16 of the heating station 11.
- the winding dome 12 of the curling iron 10 is inserted in the corresponding shape 17 of the heating block 18 hanging.
- the holding forces are applied by the magnetic effect between the at least one permanent magnet 20 in the heating block 18 and the magnetic material introduced into the winding dome 12.
- the force component acting essentially opposite to these magnetic forces results from the gravitational force.
- the curling iron 10 simply falls down from the heating block 18 after reaching the desired temperature value, preferably from a heat-resistant and heat-resistant one Insulating material produced storage 22, which in the present exemplary embodiment has a shape 23 for receiving the winding mandrel 12 of the curling iron 10.
- any spring elements for lifting the winding mandrel 12 from the heating block 18 can be dispensed with. However, care must be taken to ensure that the heating station 11 cannot be operated in an improper position.
- Improper positioning is particularly the case when the heating station 11 is set up in the side or head position, since then the force components of the releasing or attracting forces are aligned either parallel or perpendicular to one another and, in extreme cases, the winding mandrel 12 cannot be lifted off the heating block 18.
- Such incorrect handling can be excluded by a suitable design of the housing 16 of the heating station 11.
- FIG. 2 Some examples of this are shown in FIG. 2, namely an attachment of a handle 24 on the upper side or a strip 25 on the side parts of the housing 16.
- FIG. 1 A further exemplary embodiment of the curling iron according to the invention is shown in detail in FIG.
- the heating station 11 is shown in longitudinal section with the winding dome 12 inserted but lifted off.
- the curling iron 10, which in the present example has an curling scissors blade 28, is mounted with its protective cap 14 in a shoulder 29 integrally formed in the interior of the housing 16 such that it can be pivoted or pivoted.
- a rod 30 is provided above the shoulder 29 which protects the protective cap 14 of the inserted curling iron. Rod 10 covered.
- the height of the shoulder 29 is fixed relative to the shape 17 of the heating block 18 in such a way that the winding dome 12 does not have any direct thermal contact with the heating block 18 over its entire length in the " lifted-off state " .
- the magnetic force is generated by means of a ring 15 arranged in the area of the winding mandrel 12 close to the handle or a different introduction of the magnetic material and the magnet 20 arranged in the heating block 18.
- the magnet 20 is slightly recessed in the shape 17 of the heating block 18, so that there is a distance indicated by arrows 31 between the ring 15 of the winding mandrel 12 and the magnet 20 even when the curling iron 10 is at Heating in the molding 17 is attached. This measure allows the ring 15 to be directly heated via the heating block 18 and the magnet 20 acting as a thermal bridge without a substantial reduction in the magnetic force effect. This ensures that the ring temperature is essentially determined by the temperature of the winding mandrel 12 and not by the temperature of the heating block 18.
- the lifting height of the winding mandrel 12 determined by the spring constant of the spring element 21 after the end of the heating process is determined in a very advantageous manner in such a way that the heat balance of the winding mandrel is balanced in the raised state.
- a constant temperature of the winding mandrel 12 is ensured even if it is in the heating station 11 in the raised state for a long time.
- the height to be set individually depends on the individual case and must be determined individually by the responsible specialist.
- winding dome 12 from metal, preferably aluminum.
- the formation of the winding mandrel 12 as a latent heat store using storage materials such as wax, saline solution or the like can also be useful for extending the period of use of the curling iron 10.
- the invention can be further developed in such a way that, for example, the heat of combustion is used for the catalytic combustion of a gaseous fuel for heating.
- an advantageous embodiment of the invention consists in the use of two or more curling irons Connection to a single heating station, so that by alternately heating the various curling irons, a curling iron which is at the desired temperature or working temperature is always available.
- a further, very advantageous embodiment of the invention provides for the attachment of at least two ferromagnetic bodies with different Curie temperatures to the winding dome 12 of the curling iron 10.
- a user-selectable immersion depth of the winding mandrel 12 in the heating block 18 makes it possible to have at least one of the ferromagnetic bodies with different Curie temperature coincide with the permanent magnet 20. This enables a setpoint temperature of the winding mandrel 12 that can be selected within wide limits, so that this temperature can be individually adapted to the user's hair condition.
