Diese Erfindung betrifft ein Haarbehandlungsgerät und ein korrespondierendes Verfahren zur Haarbehandlung. Als Haarbehandlungsgeräte kommen hier insbesondere Haartrockner, Lockenstäbe und Haarglätter in Betracht. Die Erfindung kann sowohl im privaten Bereich als auch von Friseuren angewandt werden. Insbesondere betrifft die Erfindung eine Temperaturregelung für Haarbehandlungsgeräte und ein zugehöriges Verfahren.This invention relates to a hair treatment device and a corresponding method of hair treatment. As hair treatment equipment here especially hair dryer, curling irons and straighteners into consideration. The invention can be applied both in the private sector and by hairdressers. In particular, the invention relates to a temperature control for hair treatment equipment and an associated method.

Hintergrund der ErfindungBackground of the invention

Die Anmeldung GB 2 147 204 A (angemeldet von: J.H. Downey) offenbart einen Haarkamm, welcher einen Feuchtigkeitssensor aufweist. Dieser Kamm soll so in der Lage sein, den Trocknungszustand des Haares optisch anzuzeigen. Daher kann er beispielsweise zusammen mit einem Haartrockner verwendet werden. Eine Benutzerin könnte dann beispielsweise den Kamm in der einen Hand und den Haartrockner in der anderen Hand halten und je nach Anzeige des Kammes den Warmluftstrom des Haartrockners an auf noch feuchte Stellen des Haares richten.The registration GB 2 147 204 A (filed by: JH Downey) discloses a hair comb having a humidity sensor. This comb should be able to visually indicate the state of drying of the hair. Therefore, it can be used with a hairdryer, for example. A user could then, for example, hold the comb in one hand and the hair dryer in the other hand and, depending on the display of the comb, the warm air flow of the hair dryer on still moist areas of the hair.

Die Patentanmeldung GB 2 432 310 A1 (Jemella Ltd.) offenbart ein Glätteisen mit einer Temperaturmesseinheit und einem Schaltkreis. Diese sollen erreichen, dass das Glätteisen erst ab einer bestimmten Minimaltemperatur eingeschaltet werden kann. Geeignete Minimaltemperaturen können nach dieser Offenbarung etwa zwischen 0°C und 10°C liegen. Wie in der Anmeldung beschrieben wird, könnte das Einschalten bei Temperaturen unterhalb von einem solchen Schwellenwert schädlich sein, insbesondere da dann das Glätteisen durch gebildetes Kondenswasser beschädigt werden kann.The patent application GB 2 432 310 A1 (Jemella Ltd.) discloses a flat iron with a temperature measuring unit and a circuit. These are intended to ensure that the flat iron can only be switched on above a certain minimum temperature. Suitable minimum temperatures may be between about 0 ° C and about 10 ° C according to this disclosure. As described in the application, turn-on could be detrimental at temperatures below such a threshold, especially since the straightener can then be damaged by formed condensation.

Die Europäische Patentschrift EP 0 176 003 B1 (Wella AG) offenbart ein Verfahren zur Messung und Regelung des Feuchtigkeitsgehaltes des Haares, welches mit Haartrockenhauben verwendet werden kann. Solche Haartrockenhauben, wie sie wohl typischerweise in Frisiersalons verwendet werden, sollen mit einem Rückluftkanal ausgestattet werden. In diesem Rückluftkanal kann dann ein Luftfeuchtigkeitssensor eingebaut werden. Dieser Sensor wiederum soll ein Signal zum Abschalten des Trocknungsprogramms erzeugen.The European patent EP 0 176 003 B1 (Wella AG) discloses a method for measuring and controlling the moisture content of the hair which can be used with hair dryers. Such hair dryers, as they are typically used in hairdressing salons, should be equipped with a return air duct. An air humidity sensor can then be installed in this return air duct. This sensor in turn should generate a signal to shut down the drying program.

Die Europäische Patentanmeldung EP 1 400 187 A1 (Cho) offenbart einen Schaltkreis, mit dem die Temperatur eines Glätteisens konstant gehalten werden kann. Dieser exemplarische Schaltkreis ist wie viele andere Schaltkreise dazu bestimmt, Messdaten von einem Temperatursensor aufzunehmen und das Glätteisen auf einer voreingestellten Temperatur möglichst konstant zu halten. Der Temperatursensor wird also nicht zum Variieren der Temperatur benutzt, sondern im Gegenteil vielmehr dazu die einmal eingestellte Temperatur konstant zu halten.The European patent application EP 1 400 187 A1 (Cho) discloses a circuit with which the temperature of a flat iron can be kept constant. This exemplary circuit, like many other circuits, is designed to receive measurement data from a temperature sensor and to keep the flat iron as constant as possible at a preset temperature. The temperature sensor is therefore not used to vary the temperature, but on the contrary rather to keep the once set temperature constant.

Der Stand der Technik hat also einige Nachteile und Begrenzungen. Insbesondere wird trotz verschiedener Versuche der Temperaturregelung und der Prozeßsteuerung, keine Möglichkeit angeboten, in bequemer Weise die Temperatur automatisch zu steuern.The prior art thus has some disadvantages and limitations. In particular, despite various attempts at temperature control and process control, there is no way to conveniently automatically control the temperature.

Die vorliegende Erfindung macht es sich zur Aufgabe, ein Haarbehandlungsgerät und ein korrespondierendes Verfahren anzubieten, mit dem Haareigenschaften gemessen werden und Temperatursteuerung im Haarbehandlungsgerät genutzt werden.The object of the present invention is to provide a hair treatment device and a corresponding method, with which hair properties are measured and temperature control is used in the hair treatment device.

Diese Aufgabe wird durch ein Haarbehandlungsgerät nach Anspruch 1 und ein Verfahren zur Haarbehandlung nach Anspruch 11 gelöst.This object is achieved by a hair treatment device according to claim 1 and a method for hair treatment according to claim 11.

Beschreibungdescription

Die Erfindung betrifft ein Haarbehandlungsgerät und ein korrespondierendes Verfahren zur Haarbehandlung. Haarbehandlungsgerät, welches geeignet ist, Haare zu erwärmen und welches dazu ein Heizteil aufweist, welches auf eine Anfangstemperatur aufgeheizt wird und dessen Temperatur über eine Temperaturregelung geregelt wird, wobei dem Haarbehandlungsgerät ein Sensor zugeordnet ist, welcher Daten mißt, aus denen sich ein Kennwert abhängig von Zustand der Haare erzeugen lässt, wobei der Kennwert die Temperaturregelung beeinflusst.The invention relates to a hair treatment device and a corresponding method for hair treatment. Hair treatment device, which is suitable to heat hair and which has a heating part, which is heated to an initial temperature and the temperature is controlled by a temperature control, the hair treatment device is associated with a sensor which measures data from which a characteristic depends on Condition of the hair can produce, with the characteristic value affects the temperature control.

Die vorliegende Erfindung betrifft also allgemein ein Haarbehandlungsgerät. Diese kann ein Haarbehandlungsgerät zur professionellen Verwendung sein, also eines, welches in der Regel in einem Frisiersalon verwendet wird. Dies sind insbesondere auch Trockenhauben. Das Haarbehandlungsgerät kann ebenfalls eines der üblichen Geräte zur Verwendung im privaten Bereich sein. Dazu gehören insbesondere Haartrockner, Warmluftbürsten, Lockenstäbe und Glätteisen. Diese Geräte weisen alle jeweils mindestens ein Heizteil auf, welches abhängig vom Gerät in verschiedener Form ausgeführt wird. Bei Haartrocknern und Trockenhauben gibt es in der Regel eine Luftheizung, welche typischerweise aus einer Anordnung beheizter Drähte besteht. Andere Geräte verwenden meist ebenfalls Widerstandsheizungen, beispielsweise in der Form von Heizplatten im Fall eines Glätteisens. In einzelnen Fällen ist auch eine nicht elektrische Heizung vorgesehen, so z.B. bei gasgetriebenen Geräten.The present invention thus generally relates to a hair treatment device. This can be a hair treatment device for professional use, so one that is usually used in a hair salon. These are especially dry hoods. The hair treatment device may also be one of the usual devices for use in the private sector. These include in particular hair dryers, hot air brushes, curling irons and straighteners. These devices each have at least one heating element, which is executed in various forms depending on the device. For hair dryers and drying hoods There is usually an air heater, which typically consists of an array of heated wires. Other devices usually also use resistance heaters, for example in the form of hot plates in the case of a smoothing iron. In some cases, a non-electric heating is provided, such as in gas-powered devices.

Beim Einschalten des Gerätes wird dieses Heizteil auf eine Anfangstemperatur aufgeheizt. Im Einzelfall wird das Gerät schon benutzt, bevor diese Temperatur erreicht wird. Die Anfangstemperatur ist aber beim Einschalten des Gerätes vorgegeben. Es kommt beispielsweise ein einfacher Einschaltknopf in Betracht, bei dem eine weitere Temperaturauswahl nicht möglich ist. Neben dem Einschaltknopf kann auch ein Regler vorgesehen sein, mit dem eine Anfangstemperatur ausgewählt werden kann.When the device is switched on, this heating element is heated to an initial temperature. In individual cases, the device is already used before this temperature is reached. The initial temperature is specified when switching on the device. It comes, for example, a simple power button into consideration, in which a further temperature selection is not possible. In addition to the power button and a controller may be provided with which an initial temperature can be selected.

Die Temperatur des Heizteils des Haarbehandlungsgerätes wird nun über einen Temperaturregelung geregelt. Diese Temperaturregelung kann bereits die Anfangstemperatur regeln oder sie wird aktiv, sobald die Anfangstemperatur erreicht wird und dient dazu, den weiteren Temperaturverlauf zu regeln. Das Abschalten des Gerätes ist dabei jedoch nicht Aufgabe der Temperaturregelung. Allerdings kann es alternativ oder zusätzlich, insbesondere bei Glätteisen und Lockenstäben, auch in Betracht kommen, dass die Temperaturregelung das Gerät auch abschalten kann. Dabei kommt die temporäre und die permanente Abschaltung des Heizteils in Betracht.The temperature of the heating part of the hair treatment device is now controlled by a temperature control. This temperature control can already regulate the initial temperature or it becomes active as soon as the initial temperature is reached and serves to regulate the further temperature profile. Switching off the device is not the task of the temperature control. However, alternatively or additionally, in particular with straighteners and curling irons, it may also be considered that the temperature control can also switch off the device. Here, the temporary and permanent shutdown of the heating element comes into consideration.

Erfindungsgemäß ist dem Haarbehandlungsgerät ein Sensor zugeordnet. Dieser misst Daten, aus denen sich ein Kennwert abhängig vom Zustand der Haare erzeugen lässt. Der Sensor kann beispielsweise in das Haarbehandlungsgerät eingebaut sein. Es kommt alternativ oder zusätzlich aber auch in Frage, dass der Sensor in einem Aufsatzteil zum Haarbehandlungsgerät platziert ist. Ein solches Aufsatzteil wäre beispielsweise eine Aufsteckdüse für einen Haartrockner. Es kommt alternativ oder zusätzlich auch in Frage, dass der Sensor in einem separaten Bauteil zur Verfügung gestellt wird, welches im Wesentlichen nur Messaufgaben übernimmt.According to the hair treatment device, a sensor is assigned. This measures data from which a characteristic value can be generated depending on the condition of the hair. The sensor may be incorporated, for example, in the hair treatment device. Alternatively or additionally, however, it is also possible for the sensor to be placed in an attachment to the hair treatment device. Such an attachment would be, for example, a slip-on nozzle for a hair dryer. Alternatively or additionally, it is also possible for the sensor to be made available in a separate component, which essentially only performs measuring tasks.

Dieser Sensor kann verschiedene geeignete Daten messen, aus denen sich ein Kennwert abhängig vom Zustand der Haare erzeugen lässt. Solche Daten sind beispielsweise die Haartemperatur, die Haarfestigkeit oder die Haarfeuchte. Diese Daten können direkt am Haar gemessen werden, sie können aber auch indirekt gemessen werden. Beispielsweise hat die Haartemperatur Einfluß auf die Temperatur eines am Haar anliegenden Bauteils, wie beispielsweise eines Heizteils zum Kontakt mit dem Haar. Weitere nützliche Daten können auch durch Messung der Zugkraft erzeugt werden, mit denen Haare über mindestens eine Fläche gezogen werden. Die Messung kann mit einer einzelnen Fläche erfolgen oder mit mehreren, insbesondere zwei Flächen. Dabei können die zwei Flächen gegeneinandergepresst werden. Die beiden Heizflächen eines Haarglätters oder die Heiz- und die Klemmfläche eines Lockenstabes kommen dazu in Betracht.This sensor can measure various suitable data from which a characteristic value can be generated depending on the condition of the hair. Such data are, for example, the hair temperature, hair firmness or hair moisture. These data can be measured directly on the hair, but they can also be measured indirectly. For example, the hair temperature has an influence on the temperature of a component applied to the hair, such as a heating member for contact with the hair. Other useful data can also be generated by measuring the tensile force with which hair is pulled over at least one surface. The measurement can be carried out with a single surface or with several, in particular two surfaces. The two surfaces can be pressed against each other. The two heating surfaces of a hair straightener or the heating and the clamping surface of a curling iron come into consideration.

Aus diesen Daten soll ein Kennwert abhängig vom Zustand der Haare erzeugt werden. Dieses kann ein aus bloß zwei Werten ausgewählter Kennwert sein oder ein aus einer vorgegebenen Anzahl von Werten ausgewählter Kennwert oder auch ein aus einem Kontinuum von Zahlenwerten ausgewählter Kennwert. Erfindungsgemäß soll nun dieser Kennwert die Temperaturregelung beeinflussen. In Betracht kommt als einfache Form der Beeinflussung das Erhöhen oder Absenkung der Temperatur. Es wäre auch möglich, dass der Kennwert die Temperatur entlang einer bestimmten Temperaturkurve variiert.From this data, a characteristic value is to be generated depending on the condition of the hair. This may be a characteristic value selected from a mere two values, or a characteristic value selected from a predetermined number of values, or a characteristic value selected from a continuum of numerical values. According to the invention, this parameter should now influence the temperature control. A simple form of influencing is the raising or lowering of the temperature. It would also be possible for the characteristic value to vary the temperature along a specific temperature curve.

Es hat sich als besonders zweckmäßig erwiesen, wenn bei dem Haarbehandlungsgerät der Sensor Temperaturdaten ausliest. Insbesondere kommt es in Frage, ein Haarbehandlungsgerät zur Verfügung zu stellen, welches zwei Sensoren aufweist. Dabei kann ein Kennwert erzeugt werden, der eine Temperaturdifferenz ist, welche vom Zustand der Haare abhängig ist. Beispielsweise kann die Behandlungstemperatur erhöht werden, wenn die Temperaturdifferenz groß ist, oder erniedrigt werden, wenn sie klein ist.It has proven to be particularly useful when the sensor reads temperature data in the hair treatment device. In particular, it is possible to provide a hair treatment device which has two sensors. In this case, a characteristic value can be generated, which is a temperature difference, which depends on the condition of the hair. For example, the treatment temperature may be increased when the temperature difference is large, or lowered when it is small.

Es hat sich gezeigt, dass der Einsatz von Sensoren und einer erfindungsgemäßen Temperaturregelung besonders vorteilhaft bei Haarglättern oder sogenannten Glätteisen ist. Solche Geräte weisen typischerweise zwei Arme auf, welche auseinander- und zusammengeklappt werden können und zwischen denen das Haar hindurchgeführt wird. Mindestens ein Arm weist in der Regel eine Heizfläche auf, häufig weisen beide Arme je eine Heizfläche auf. Der gegenüberliegende Arm kann eine Anpressfläche aufweisen, mit welcher das Haar auf die Heizfläche gedrückt wird. Die Gestaltung des Haarglätters ist aber häufig auch symmetrisch, d.h. es sind zwei gegenüberliegende Heizflächen vorgesehen, welche für die jeweils andere Heizfläche auch als Anpreßfläche dienen. Haare werden in einer Durchführungsrichtung durch den Haarglätter geführt. Dabei werden sie zunächst an einem vorderen Bereich einer ersten Heizfläche vorbei geführt und dann an einem hinteren Bereich einer Heizfläche, also an einem Bereich, der in Durchführungsrichtung hinter dem vorderen Bereich liegt. Erfindungsgemäß kann nun im vorderen Bereich ein erster Sensor vorgesehen sein und im hinteren Bereich ein zweiter Sensor. Dieser Sensor misst dann an der Heizfläche jeweils eine Temperatur. Dabei kommt es zu Temperaturunterschieden, welche auch von der Art und dem Zustand des durchgeführten Haares abhängen.It has been found that the use of sensors and a temperature control according to the invention is particularly advantageous in hair straighteners or so-called flat irons. Such devices typically have two arms which can be unfolded and folded and between which the hair is passed. At least one arm usually has a heating surface, often both arms each have a heating surface. The opposite arm may have a contact surface, with which the hair is pressed onto the heating surface. However, the design of the Haarglätters is often symmetrical, ie there are two opposite heating surfaces provided, which also serve as a contact surface for the other heating surface. Hair is passed through the hair straightener in one direction. In this case, they are first guided past a front region of a first heating surface and then at a rear region of a heating surface, that is to say at a region which lies behind the front region in the direction of passage. According to the invention, a first sensor can now be provided in the front region and a second sensor in the rear region. This sensor then measures one on the heating surface Temperature. This results in temperature differences, which also depend on the nature and condition of the performed hair.

In einem weiteren Aspekt betrifft die vorliegende Erfindung auch ein Verfahren zur thermischen Haarbehandlung, bei dem die Behandlungstemperatur abhängig vom Zustand der Haare automatisch geregelt wird. Ein solches Verfahren kann insbesondere eines sein, bei dem ein Haarglätter als Gerät zur Haarbehandlung eingesetzt wird. Dabei kann der Erstkontakt des Haarbehandlungsgerätes mit dem Haar bei einer voreingestellten Temperatur stattfinden. Diese voreingestellte Temperatur kann dann abhängig von der Temperaturdifferenz, die zwischen erstem und zweitem Sensor gemessen wird, verändert werden. Insbesondere kommt es in Betracht, dass die voreingestellte Temperatur erhöht wird, wenn zwischen den beiden Sensoren eine große Temperaturdifferenz gemessen wird. Die voreingestellte Temperatur wird dagegen erniedrigt, wenn zwischen den beiden Sensoren eine kleine Temperaturdifferenz gemessen wird.In a further aspect, the present invention also relates to a process for thermal hair treatment in which the treatment temperature is automatically regulated depending on the condition of the hair. Such a method may, in particular, be one in which a hair straightener is used as a device for hair treatment. In this case, the first contact of the hair treatment device with the hair can take place at a preset temperature. This preset temperature can then be varied depending on the temperature difference measured between the first and second sensors. In particular, it is considered that the preset temperature is increased when a large temperature difference is measured between the two sensors. By contrast, the preset temperature is lowered when a small temperature difference is measured between the two sensors.

Die Erfindung kann mit einem Lockenstab als Haarbehandlungsgerät eingesetzt werden. Ein geeigneter Lockenstab ist in Fig. 1 abgebildet. Er weist ein Griffteil 110 auf, welches mit einem Sichtfenster 112 ausgestattet ist. Dieses Sichtfenster 112 dient dazu, den Füllstand einer Gaskartusche sichtbar zu machen. Die vorliegende Erfindung kann also auch mit nicht strombetriebenen Geräten verwendet werden, nämlich beispielsweise mit gasgetriebenen, die etwa durch katalytische Gasverbrennung eine Heizleistung erzeugen. Das Gerät weist einen Schalter 120 auf, welcher als Ein-/Ausschalter dient. Es ist im Prinzip auch denkbar, dass der Schalter die Auswahl mehr als einer vorgegebenen Anfangstemperatur erlaubt. Das Gerät weist ferner eine Haarbehandlungseinheit auf, welche einen Zylinderstab 132 und eine Klammer 134 umfasst. Mit Hilfe des Bedienhebels 136 kann die Klammer 134 vom Zylinderstab 132 gelöst werden und zu lockendes Haar wird zwischen Zylinderstab 132 und Klammer 134 eingelegt. Die Anbringung von mindestens einem Sensor oder auch von zwei Sensoren kommt an verschiedenen Stellen des Lockenstabs 100 in Betracht. Günstig ist insbesondere den Bereich 140 zur Anbringung eines ersten Sensors auszunutzen und alternativ oder zusätzlich den Bereich 142 zur Anbringung eines zweiten Sensors. Die Sensoren liegen dann links und rechts von der Klammer 134. Folglich sind sie in Kontakt mit Haaren, die dem Lockenstab gerade zugeführt werden und ferner mit Haaren, die den Bereich des Lockenstabs gerade verlassen.The invention can be used with a curling iron as a hair treatment device. A suitable curling iron is in Fig. 1 displayed. It has a grip part 110, which is equipped with a viewing window 112. This window 112 is used to make the level of a gas cartridge visible. Thus, the present invention can also be used with non-powered equipment, namely, for example, with gas driven, which generate a heating power as by catalytic gas combustion. The device has a switch 120, which serves as an on / off switch. It is also conceivable in principle that the switch allows the selection more than a predetermined initial temperature. The apparatus further includes a hair treatment unit comprising a cylinder rod 132 and a bracket 134. With the help of the operating lever 136, the clamp 134 can be released from the cylinder rod 132 and hair to be curled is inserted between the cylinder rod 132 and the bracket 134. The attachment of at least one sensor or of two sensors comes at different points of the curling iron 100 into consideration. In particular, the area 140 for attaching a first sensor can be used to advantage, and alternatively or additionally the area 142 for mounting a second sensor. The sensors are then to the left and to the right of the clamp 134. Consequently, they are in contact with hairs that are being fed to the curling iron and also with hair that is just leaving the area of the curling iron.

Fig. 2 zeigt einen Haarglätter, welcher ein anderes erfindungsgemäßes Haarbehandlungsgerät darstellt. Der Haarglätter 200 weist einen Griffbereich 210 auf und ein Haarbehandlungsbereich 230. Der Griffbereich umfasst einen ersten Griffbereich 212 und einen zweiten Griffbereich 214, welche jeweils den Armen des Haarglätters 200 zugeordnet sind. Die beiden Arme sind durch ein Verbindungsgelenk 216 verbunden. Am Ende des Haarglätters 200 ist ein Kabel 218 vorgesehen. Es handelt sich also um ein elektrisch betriebenes Haarbehandlungsgerät. Ferner ist ein Temperaturregler 220 vorgesehen. In der abgebildeten Form des Drehrades ist es leicht möglich eine gewünschte Anfangstemperatur vorzuwählen. Der Temperaturregler 220 kann zusätzlich auch als Einschalter dienen. Alternativ kann das Gerät beispielsweise durch Verbindung des Kabels 218 mit dem Netz und durch Abziehen des Kabels vom Stromnetz ein- bzw. ausgeschaltet werden. Der Haarbehandlungsabschnitt 230 umfasst den Haarbehandlungsabschnitt des ersten Arms 232 und den Haarbehandlungsabschnitt des zweiten Arms 234. Am ersten Arm 232 ist ein Griffbereich 236 erkennbar. Ein ähnlicher Griffbereich kann gegenüberliegend auch am Haarbehandlungsende des zweiten Arms 234 vorgesehen werden. Im Haarbehandlungsbereich 234 des zweiten Arms 234 ist ein Heizteil 238 sichtbar. Ein korrespondierendes Heizteil kann im Haarbehandlungsbereich des ersten Arms 232 ebenfalls vorgesehen werden. Alternativ kann dort eine unbeheizte Anpressplatte vorgesehen sein. Fig. 2 shows a hair straightener, which is another hair treatment device according to the invention. The hair straightener 200 has a grip region 210 and a hair treatment region 230. The grip region comprises a first grip region 212 and a second grip region 214, which are respectively associated with the arms of the hair straightener 200. The two arms are connected by a connecting joint 216. At the end of the hair straightener 200, a cable 218 is provided. It is therefore an electrically operated hair treatment device. Furthermore, a temperature controller 220 is provided. In the illustrated form of the rotary wheel, it is easily possible to preselect a desired starting temperature. The temperature controller 220 may additionally serve as a power switch. Alternatively, the device may be turned on or off, for example, by connecting the cable 218 to the mains and disconnecting the cable from the mains. The hair treatment portion 230 includes the hair treatment portion of the first arm 232 and the hair treatment portion of the second arm 234. On the first arm 232, a grip portion 236 can be seen. A similar grip region may be provided opposite also at the hair treatment end of the second arm 234. In the hair treatment area 234 of the second arm 234, a heating part 238 is visible. A corresponding heating part may also be provided in the hair treatment area of the first arm 232. Alternatively, there may be provided an unheated pressure plate.

Das Heizteil 238 kann mit einem oder zwei oder mehr Sensoren ausgestattet werden. Günstig ist es, einen Sensor im Bereich 240 und einen weiteren Sensor im Bereich 242 vorzusehen. Die Sensoren können dann die Temperatur von Haaren messen, welche in Durchführrichtung zunächst den Bereich 240 und dann den Bereich 242 passieren.The heating part 238 may be equipped with one or two or more sensors. It is advantageous to provide one sensor in the area 240 and another sensor in the area 242. The sensors can then measure the temperature of hair, which first pass through the region 240 and then the region 242 in the direction of execution.

Fig. 3 zeigt schematisch einen Querschnitt durch ein Heizteil, wie es beispielsweise als erstes Heizteil 238 in dem Haarglätter 200 eingesetzt werden kann. Man sieht einen Schnitt in Querrichtung, bei dem die Heizfläche 250 nach unten weist. Die Heizfläche 250 ist Teil eines u-förmigen in der Regel metallischen Heizteils. Auf der Rückseite des Heizteils, gegenüber der Heizfläche 250, ist ein Heizelement 260 vorgesehen. Dieses wird im Wesentlichen durch resistive Heizung aufgeheizt. Es gibt seine Wärme an das Heizteil und die Heizfläche 250 weiter. Seitlich an dem Heizteil, nämlich am ersten der u-förmigen Schenkel ist ein erster Sensor 270 vorgesehen. Hier läge bei geeignetem Einbau des Heizteils in einen Haarglätter der Bereich 240 des ersten Sensors. Gegenüberliegend, am anderen seitlichen Schenkel der u-Form ist ein zweiter Sensor 272 vorgesehen. Hier läge entsprechend der Bereich 242 des zweiten Sensors. Zusätzliche Sensoren können vorgesehen werden, auch jeweils im Bereich 240 und im Bereich 242. Wenn die Heizfläche 250 im Kontakt mit Haaren steht, kann der erste Sensor 270 einen Temperaturwert messen, der charakteristisch für dem Haarglätter zugeführtes Haar ist und der zweite Sensor 272 kann einen Wert messen, der charakteristisch ist für Haar, das aus dem Haarglätter austritt. Ferner ist hier ein dritter Sensor 274 vorgesehen, der sich in unmittelbarer Nachbarschaft zum Heizelement 260 befindet. Mit dem dritten Sensor kann ein noch genauerer Temperaturverlauf bestimmt werden. Der dritte Sensor kann insbesondere auch dazu dienen, die Temperatur des Heizelementes auf einem bestimmten konstanten Wert zu halten, solange es nicht gilt, diesen zu verändern. Fig. 3 schematically shows a cross section through a heating part, as it can be used for example as the first heating part 238 in the hair straightener 200. It can be seen a cross-section, in which the heating surface 250 faces downward. The heating surface 250 is part of a U-shaped, usually metallic heating part. On the back of the heating element, opposite the heating surface 250, a heating element 260 is provided. This is essentially heated by resistive heating. It gives its heat to the heating part and the heating surface 250 further. Laterally on the heating part, namely on the first of the U-shaped legs, a first sensor 270 is provided. If the heating element were installed in a hair straightener, the area 240 of the first sensor would be located here. Opposite, on the other lateral leg of the u-shape, a second sensor 272 is provided. Here would be corresponding to the area 242 of the second sensor. Additional sensors may be provided, also in the region 240 and in region 242, respectively. When the heating surface 250 is in contact with hair, the first sensor 270 may measure a temperature value characteristic of hair supplied to the hair straightener and the second sensor 272 may measure a temperature Measure the value characteristic of hair exiting the hair straightener. Furthermore, here a third sensor 274 is provided, which is located in the immediate vicinity of the heating element 260. With the third sensor, an even more accurate temperature profile can be determined. The third sensor can in particular also serve to keep the temperature of the heating element at a certain constant value, as long as it does not apply to change this.

In Fig. 4 ist in perspektivischer Aufsicht ein Haartrockner 300 gezeichnet. Als ein markantes Element weist er ein Griffteil 310 auf. Dieses trägt den Einschalter 320. Der Einschalter dient entweder dazu, den Luftstrom auf eine feste Temperatur zu bringen, häufig aber gibt es auch zwei oder drei Temperaturstufen, welche mit dem einen Schalter wählbar sind. Als Haarbehandlungsteil 330 des Haartrockners 300 kann im Wesentlich die Warmluftauslassdüse angesehen werden. Diese bläst Warmluft in der Auslassrichtung 332 aus. Das Haarbehandlungsteil 330 trägt auch das Verbindungselement 334, das in der Form einer nutartigen Vertiefung ausgeführt ist. Dieses Verbindungselement 334 ermöglicht die Verbindung mit dem Aufsatzteil 400. Das Aufsatzteil 400 ist mit einem korrespondierenden Verbindungselement 410 ausgestattet, welches als Nase ausgebildet ist, die in die Nut eingreifen kann. Das Aufsatzteil 400 weist eine Vielzahl von Luftaustrittselementen 420 auf. Diese sind stab-oder röhrenförmig ausgeführt. Durch die Luftaustrittselemente 420 wird warme Luft gerade bei einer gelockten Frisur tief ins Haar eingebracht. Luft kann zusätzlich auch am Fuß der Luftaustrittselemente durch zusätzliche, hier nicht erkennbare Düsen austreten. Zwischen den Spitzen der Luftaustrittselemente und ihren Fußteilen liegt ein Abstand von typischerweise einigen Zentimetern. In solchem Abstand können erste und zweite Sensoren vorgesehen werden. Beispielsweise kann am Fuß der Luftaustrittselemente 420 der Bereich 440 eines ersten Sensors liegen. Am Ende der Luftaustrittselemente 420 kann der Bereich 442 eines zweiten Sensors liegen. Dort angebrachte Sensoren können beispielsweise wiederum Temperatursensoren sein, so dass eine Temperaturdifferenz gemessen werden kann. Es kommt aber ebenfalls in Betracht, dass eine Feuchtigkeitsdifferenz gemessen werden wird. Aufgrund der entsprechenden Messwerte kann wiederum ein Kennwert erzeugt werden, mit dem die Temperatur des Haartrockners 300 reguliert werden kann. Die Übertragung des Kennwertes zum Haarbehandlungsgerät, hier dem Haartrockner, kann etwas durch ein Kabel oder drahtlos erfolgen.In Fig. 4 is drawn in a perspective view a hairdryer 300. As a striking element, it has a grip part 310. This carries the power switch 320. The power switch is used either to bring the air flow to a fixed temperature, but often there are also two or three temperature levels, which can be selected with the one switch. As a hair treatment part 330 of the hair dryer 300, the hot air outlet nozzle can be considered essentially. This blows hot air in the outlet direction 332. The hair treating member 330 also supports the connecting member 334, which is in the form of a groove-like depression. This connection element 334 allows the connection with the attachment part 400. The attachment part 400 is equipped with a corresponding connection element 410, which is designed as a nose, which can engage in the groove. The attachment 400 has a plurality of air outlet elements 420. These are rod-shaped or tubular. The air outlet elements 420 warm air is introduced deep into the hair, especially in a curly hairstyle. Air can also emerge at the foot of the air outlet elements by additional, not visible here nozzles. Between the tips of the air outlet elements and their foot parts is a distance of typically a few centimeters. At such a distance, first and second sensors can be provided. For example, at the foot of the air outlet elements 420, the area 440 of a first sensor may be located. At the end of the air outlet elements 420 may be the area 442 of a second sensor. Sensors mounted there can in turn be temperature sensors, for example, so that a temperature difference can be measured. However, it is also contemplated that a moisture difference will be measured. On the basis of the corresponding measured values, a characteristic value can again be generated with the temperature of the hair dryer 300 can be regulated. The transmission of the characteristic value to the hair treatment device, here the hair dryer, can be done somewhat by a cable or wirelessly.

Die Vorsehung zweier Sensoren an den näher beschriebenen Stellen, wie auch andere hierin beschriebene Ausführungsformen der Erfindung, erlauben also einen sehr bequemen, automatisierten und effizienten Haartrocknungsprozess vorzusehen und entsprechende Geräte anzubieten.The provision of two sensors at the points described in detail, as well as other embodiments of the invention described herein, thus make it possible to provide a very convenient, automated and efficient hair-drying process and to offer corresponding devices.
