Description

Die vorliegende Erfindung betrifft ein Haarformgerät mit einem Gehäuse, mit zwei über ein Gelenk miteinander verbundenen Formteilen zum Formen von Haaren, wobei zumindest eines der Formteile wenigstens ein Heizelement zum Erwärmen der Haare umfasst, und mit zumindest einem Kühlelement, das dem zumindest einen Formteil zugeordnet ist und sich zum Abkühlen der an dem Heizelement erwärmten Haare eignet, und das drehbar am Gehäuse angebracht ist.The present invention relates to a hair styling device with a housing, with two molded parts connected to one another for shaping hair, wherein at least one of the molded parts comprises at least one heating element for heating the hair, and with at least one cooling element associated with the at least one molded part and is suitable for cooling the heated hair on the heating element, and which is rotatably mounted on the housing.

Das Umformen und Stylen mit herkömmlichen Haarformgeräten kann aufgrund der hohen Temperaturen eine große Belastung für das Haar darstellen, was ein Austrocknen der Haare zum Ergebnis haben kann. Um diesem Problem des Austrocknens entgegenzutreten, ist bekannt, Haarformgeräte mit zwei Formteilen bereitzustellen, wobei die Formteile ein Heizelement und ein in Anwendungsrichtung nachgeordnetes Kühlelement umfassen. Diese Kühlelemente sind dabei jeweils starr an die Formteile angebracht, wodurch sich die Kühlelemente mit zunehmender Anwendungsdauer nachteilig erwärmen und dadurch ihre kühlende Wirkung verlieren, was zu einer Verschlechterung des Stylingergebnisses führen kann.Forming and styling with conventional hair styling equipment can be a great burden on hair due to high temperatures, which can result in hair drying out. To counteract this problem of dehydration, it is known to provide hair styling devices with two mold parts, the mold parts comprising a heating element and a downstream cooling element in the application direction. These cooling elements are each rigidly attached to the moldings, whereby the cooling elements adversely heat with increasing duration of use and thereby lose their cooling effect, which can lead to a deterioration of the styling result.

Ein gattungsbildendes Haarformgerät ist beispielsweise aus der JP 2001 104036 A bekannt. Darüber hinaus sei noch auf die aus der US 4,602,143 A sowie der DE 10 2006 037 647 A1 bekannten Haarformgeräte verwiesen.A generic hair styling device is for example from the JP 2001 104036 A known. In addition, it is still on the from the US 4,602,143 A as well as the DE 10 2006 037 647 A1 referenced hair styling devices.

Aufgabe der vorliegenden Erfindung ist es, ein verbessertes Haarformgerät anzugeben, das sich durch eine verringerte Wärmeaufnahme des Kühlelements auszeichnet, wodurch mit Vorteil ein verbessertes Stylingergebnis erzielt werden kann.Object of the present invention is to provide an improved hair styling device, which is characterized by a reduced heat absorption of the cooling element, whereby advantageously an improved styling result can be achieved.

Diese Aufgabe wird durch ein Haarformgerät mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a hair styling device with the features of claim 1.

Die vorliegende Erfindung geht aus von einem Haarformgerät mit einem Gehäuse, mit zwei über ein Gelenk miteinander verbundenen Formteilen zum Formen von Haaren und mit zumindest einem Kühlelement. Zumindest eines der Formteile umfasst wenigstens ein Heizelement zum Erwärmen der Haare. Das Kühlelement ist dem zumindest einen Formteil zugeordnet und eignet sich zum Abkühlen der an dem Heizelement erwärmten Haare. Das Kühlelement ist drehbar am Gehäuse angebracht.The present invention is based on a hair styling device with a housing, with two molded parts which are connected to one another via a joint for shaping hair and with at least one cooling element. At least one of the mold parts comprises at least one heating element for heating the hair. The cooling element is the at least one molded part assigned and is suitable for cooling the heated hair on the heating element. The cooling element is rotatably mounted on the housing.

Drehbar bedeutet hierbei, dass das Kühlelement mit einem Befestigungselement an dem Gehäuse befestigt ist, wobei das Kühlelement zum Befestigungselement und zum Gehäuse drehbar gelagert ist.Rotatable here means that the cooling element is fastened with a fastening element on the housing, wherein the cooling element is rotatably mounted to the fastening element and the housing.

Dem Formteil zugeordnet bedeutet insbesondere, dass das Kühlelement fixiert zum Formteil angeordnet ist, sodass mit dem Formteil geformte Haare an dem Kühlelement nach deren Erwärmen gekühlt werden. Hierzu besteht direkt oder indirekt zwischen dem Formteil und dem Kühlelement vorzugsweise eine feste Verbindung. Wird demnach das Formteil mittels des Gelenkes relativ zum weiteren Formteil bewegt, bewegt sich aufgrund der festen Verbindung das Kühlelement ebenfalls relativ zum weiteren Formteil. Beispielsweise ist das Kühlelement an dem Formteil selbst befestigt, insbesondere dem Heizelement in Anwendungsrichtung nachgeordnet.Associated with the molded part means, in particular, that the cooling element is arranged fixed to the molded part, so that hair shaped with the molded part is cooled on the cooling element after it has been heated. For this purpose, there is preferably a fixed connection directly or indirectly between the molded part and the cooling element. Accordingly, if the molded part is moved relative to the further molded part by means of the joint, the cooling element likewise moves relative to the further molded part due to the fixed connection. For example, the cooling element is attached to the molded part itself, in particular downstream of the heating element in the application direction.

Das Gehäuse kann vorzugsweise die Formteile umfassen, insbesondere ausbilden. Beispielsweise weist das Gehäuse eine Längsrichtung auf, in die sich die Formteile erstrecken, wobei Außenseiten der Formteile zumindest bereichsweise, bevorzugt vollständig, durch das Gehäuse gebildet sind. Das Kühlelement kann direkt an den Formteilen angebracht sein.The housing may preferably comprise the molded parts, in particular form. For example, the housing has a longitudinal direction into which the molded parts extend, wherein outer sides of the molded parts are formed at least in regions, preferably completely, by the housing. The cooling element can be attached directly to the moldings.

Die Formteile sind bevorzugt über das Gelenk zueinander bewegbar, sodass die Formteile einen offenen Zustand und einen geschlossenen Zustand aufweisen. Das Heizelement ist dabei zwischen den Formteilen angeordnet. Im offenen Zustand können die zu formenden Haare zwischen die Formteile eingelegt werden. Zur Formung werden die Formteile anschließend geschlossen, sodass die Haare an dem Heizelement beim Durchziehen der Haare geformt werden, vorzugsweise geglättet werden.The molded parts are preferably movable relative to one another via the joint, so that the molded parts have an open state and a closed state. The heating element is arranged between the moldings. In the open state, the hair to be formed between the moldings can be inserted. To shape the moldings are then closed, so that the hairs are formed on the heating element when pulling through the hair, preferably smoothed.

Durch das drehbar gelagerte Kühlelement findet bevorzugt ein verbesserter Wärmeaustausch zwischen dem Kühlelement und der Umgebung statt, sodass die während der Haarformung vom Kühlelement aufgenommene Wärme zumindest teilweise an die Umgebung abgegeben werden kann. Dadurch kann mit Vorteil der mit zunehmender Anwendungsdauer steigenden Erwärmung des Kühlelements entgegengewirkt werden, wodurch sich vorteilhafterweise insgesamt die Temperaturerhöhung des Kühlelements im Betrieb im Vergleich zu starr angebrachten Kühlelementen reduziert. So kann mit Vorteil die kühlende Wirkung des Kühlelements auch mit zunehmender Anwendungsdauer gewährleitstet werden, wodurch mit Vorteil ein verbessertes Stylingergebnis erzielt wird.By virtue of the rotatably mounted cooling element, an improved heat exchange preferably takes place between the cooling element and the environment, so that the heat absorbed by the cooling element during hair shaping can be at least partially released to the environment. This can be counteracted with increasing advantage of the increasing duration of use heating of the cooling element, which Advantageously, the overall temperature increase of the cooling element during operation is reduced in comparison to rigidly mounted cooling elements. Thus, with advantage, the cooling effect of the cooling element can be ensured even with increasing duration of use, whereby an improved styling result is advantageously achieved.

Erfindungsgemäß sind das oder die Kühlelemente jeweils bewegbar beziehungsweise flexibel am Gehäuse befestigt und die bewegbare Befestigung jeweils durch zumindest ein Federelement ausgebildet. Dadurch kann mit Vorteil ein sehr guter Kontakt zwischen dem oder den Kühlelementen und den zu formenden Haaren hergestellt werden..According to the invention, the one or more cooling elements are each movable or flexibly attached to the housing and the movable attachment is formed in each case by at least one spring element. As a result, a very good contact between the one or more cooling elements and the hair to be formed can be produced with advantage.

  • In a preferred embodiment of the invention, the hair styling device comprises two cooling elements, which are each rotatably mounted on the housing, wherein each of the two cooling elements is associated with a molded part of the hair styling device.

Vorzugsweise umfasst jedes der Formteile jeweils ein Heizelement.Preferably, each of the mold parts each comprises a heating element.

Bevorzugt sind die Formteile identisch zueinander ausgebildet, sodass beim Zusammenführen der Formteile die Heizelemente der Formteile direkt gegenüberliegend zueinander angeordnet sind.Preferably, the mold parts are formed identical to each other, so that when merging the moldings, the heating elements of the moldings are arranged directly opposite each other.

Entsprechend sind die Kühlelemente bevorzugt direkt gegenüberliegend zueinander angeordnet. Zu formende Haare, die zwischen den Formteilen geführt werden, werden demnach von beiden Seiten an den sich gegenüberliegenden Heizelementen erst erwärmt und anschließend an den sich gegenüberliegenden Kühlelementen gekühlt.Accordingly, the cooling elements are preferably arranged directly opposite one another. Hair to be formed, which is guided between the moldings, are therefore first heated from both sides on the heating elements facing each other and then cooled at the opposite cooling elements.

Vorzugsweise weist in diesem Fall das Gehäuse, insbesondere die Formteile, zumindest einen Belüftungsschlitz, bevorzugt eine Mehrzahl von Belüftungsschlitzen zum Wärmeaustausch auf. Die Belüftungsschlitze ermöglichen insbesondere einen Wärmeaustausch des Kühlelements mit der Umgebung. Damit kann der Temperaturanstieg des Kühlelements mit zunehmender Anwendungsdauer weiter vermindert werden.Preferably, in this case, the housing, in particular the molded parts, at least one ventilation slot, preferably a plurality of ventilation slots for heat exchange. The ventilation slots in particular allow a heat exchange of the cooling element with the environment. Thus, the temperature rise of the cooling element can be further reduced with increasing duration of use.

Bei einer weiteren bevorzugten Weiterbildung der Erfindung sind das oder die Kühlelemente außerhalb des Gehäuses angebracht. Beispielsweise werden die Formteile durch das Gehäuse gebildet, wobei das Heizelement jeweils auf Innenflächen der Formteile angeordnet ist. An Außenseiten der Formteile können die Kühlelemente befestigt sein, wobei die Befestigung derart ausgebildet ist, dass die Kühlelemente geeignet sind, die zu formenden Haare nach dem Erwärmen abzukühlen.In a further preferred embodiment of the invention, the one or more cooling elements are mounted outside of the housing. For example, the molded parts are formed by the housing, wherein the heating element is arranged in each case on inner surfaces of the molded parts. On outer sides of the moldings, the cooling elements may be attached, wherein the attachment is formed such that the cooling elements are adapted to cool the hair to be formed after heating.

Bei einer weiteren bevorzugten Weiterbildung der Erfindung sind das oder die Kühlelemente jeweils drehbare Rollen. Als Rolle wird insbesondere ein zylinderförmiger Körper angesehen, vorzugsweise ein gerader Vollzylinder, der besonders bevorzugt eine kreisförmige Grundfläche aufweist. Die Rolle ist bevorzugt liegend ausgebildet und erstreckt sich entlang des dem Kühlelement zugeordneten Formteils.In a further preferred embodiment of the invention, the one or more cooling elements are each rotatable rollers.

The heating elements 2 are arranged on the inner surfaces 6 of the molded parts such that when closing the moldings, the heating elements 2 are arranged directly above one another.

Jedem der zwei Formteile zugeordnet ist ein Kühlelement 3. Die Kühlelemente 3 weisen ein wärmeleitfähiges Material auf, beispielsweise einen metallischen Werkstoff, eine Keramik oder einen Kunststoff. Die Kühlelemente 3 sind jeweils geeignet, die am Heizelement 2 erwärmten Haare 4 abzukühlen. Hierzu weisen die Kühlelemente im Betrieb Temperaturen von höchstens 100°C, bevorzugt von höchstens 90°C auf. Die Kühlelemente 3 sind ebenso wie die Heizelemente 2 beim Schließen der Formteile direkt übereinander angeordnet. Dabei sind die Kühlelemente 3 den Heizelementen 2 in Anwendungsrichtung nachgeordnet. Die Kühlelemente 3 erstreckten sich ebenso wie die Heizelemente 2 jeweils bevorzugt entlang der Längserstreckung des jeweiligen Formteils. Das Kühlelement 3 verläuft demnach jeweils parallel zum Heizelement 2 des jeweiligen Formteils.Each of the two mold parts is assigned a cooling element 3. The cooling elements 3 comprise a thermally conductive material, for example a metallic material, a ceramic or a plastic. The cooling elements 3 are each suitable for cooling the hair 4 heated on the heating element 2. For this purpose, the cooling elements during operation temperatures of at most 100 ° C, preferably of at most 90 ° C. The cooling elements 3 are just like the heating elements 2 when closing the moldings arranged directly above each other. The cooling elements 3 are arranged downstream of the heating elements 2 in the application direction. The cooling elements 3 as well as the heating elements 2 each extend preferably along the longitudinal extent of the respective molded part. Accordingly, the cooling element 3 runs parallel to the heating element 2 of the respective molded part.

Zu formende Haare 4, die an den Innenflächen 6 zwischen die Formteile und somit zwischen die Heizelemente 2 und Kühlelemente 3 gelegt werden, können zuerst an den Heizelementen 2 erwärmt, dadurch geformt, insbesondere geglättet, und anschließend an den Kühlelementen 3 gekühlt werden, wodurch sich mit Vorteil ein Austrocknen der Haare reduziert.To form hairs 4, which are placed on the inner surfaces 6 between the moldings and thus between the heating elements 2 and cooling elements 3, can first be heated to the heating elements 2, thereby shaped, in particular smoothed, and then cooled to the cooling elements 3, whereby with advantage a drying of the hair is reduced.

Die Kühlelemente 3 sind an einem Gehäuse 1 des Haarformgeräts befestigt. Beispielsweise sind die Kühlelemente 3 innerhalb des Gehäuses 1 befestigt. Bevorzugt bildet das Gehäuse dabei die Formteile aus, wobei die Kühlelemente 3 jeweils an den Innenflächen 6 der Formteile benachbart zu der jeweiligen Heizzone 2 angebracht sind. In diesem Fall weist das Gehäuse beziehungsweise die Formteile bevorzugt Belüftungsschlitze zum Wärmeaustausch auf. Dadurch kann die während der Anwendung von den Kühlelementen 3 aufgenommene Wärme über die Belüftungsschlitze an die Umgebung abgegeben werden, was mit Vorteil eine Temperaturerhöhung der Kühlelemente mit zunehmender Anwendungsdauer verringert. Alternativ können die Kühlelemente außerhalb des Gehäuses 1 befestigt sein. Bevorzugt bildet hierbei das Gehäuse wiederum die Formteile aus, wobei die Kühlelemente 3 jeweils an Außenseiten der Formteile angebracht sind.The cooling elements 3 are attached to a housing 1 of the hair styling device. For example, the cooling elements 3 are mounted within the housing 1. In this case, the housing preferably forms the molded parts, wherein the cooling elements 3 are each attached to the inner surfaces 6 of the molded parts adjacent to the respective heating zone 2. In this case, the housing or the molded parts preferably ventilation slots for heat exchange. As a result, the heat absorbed by the cooling elements 3 during the application of heat can be released through the ventilation slots to the environment, which advantageously increases the temperature of the cooling elements with increasing Reduced application time. Alternatively, the cooling elements may be fastened outside the housing 1. In this case, the housing in turn preferably forms the molded parts, wherein the cooling elements 3 are each attached to outer sides of the molded parts.

Zur Befestigung der Kühlelemente 3 am Gehäuse 1 finden bevorzugt Federelemente 5 Verwendung. Insbesondere ist jeweils ein Kühlelement 3 mit einem Federelement 5 an dem Gehäuse 1 befestigt, wodurch die Kühlelemente 3 abhängig von der Federhärte relativ zum Gehäuse 1 bewegbar sind. Dadurch kann mit Vorteil ein flexibler Kontakt zwischen den Kühlelementen 3 und den zu formenden Haaren 4 hergestellt werden.For fixing the cooling elements 3 on the housing 1 are preferably spring elements 5 use. In particular, in each case a cooling element 3 is fixed with a spring element 5 to the housing 1, whereby the cooling elements 3 are movable relative to the housing 1 depending on the spring hardness. As a result, a flexible contact between the cooling elements 3 and the hairs 4 to be formed can be produced with advantage.

Die Kühlelemente 3 sind drehbar am Gehäuse 1 gelagert. Beispielsweise sind die Kühlelemente 3 als Rollen ausgebildet, die in eine Drehrichtung D drehbar sind. Die Drehrichtung ist dabei abhängig zu der Durchziehrichtung der Haare 4. Ist die Durchziehrichtung in Figur 1 beispielsweise nach rechts gerichtet, drehen sich die Kühlelemente 3 in Richtung des jeweils dargestellten Pfeils. Die Kühlelemente 3 drehen sich dabei bei der Anwendung des Haarformgeräts aufgrund des Durchziehens der Haare 4 durch die Formteile selbständig.The cooling elements 3 are rotatably mounted on the housing 1. For example, the cooling elements 3 are formed as rollers which are rotatable in a direction of rotation D. The direction of rotation is dependent on the pull-through direction of the hair 4. Is the pull-through in FIG. 1 for example, directed to the right, the cooling elements 3 rotate in the direction of the arrow shown in each case. The cooling elements 3 rotate while using the hair styling device due to the pulling of the hair 4 through the moldings independently.

Durch die drehbare Lagerung der Kühlelemente 3 findet mit Vorteil ein verbesserter Wärmeaustausch zwischen den Kühlelementen 3 und ihrer Umgebung statt. Dadurch kann die während der Anwendung des Haarformgeräts von den Kühlelementen 3 aufgenommene Wärme teilweise an die Umgebung abgegeben werden. So kann mit Vorteil die kühlende Wirkung der Kühlelemente 3 auch mit zunehmender Anwendungsdauer gewährleitstet werden, wodurch mit Vorteil ein verbessertes Stylingergebnis erzielt werden kann.The rotatable mounting of the cooling elements 3 advantageously results in an improved heat exchange between the cooling elements 3 and their surroundings. As a result, the heat absorbed by the cooling elements 3 during the application of the hair styling device can be partially released to the environment. Thus, with advantage, the cooling effect of the cooling elements 3 can be ensured even with increasing duration of use, whereby advantageously an improved styling result can be achieved.
