Description

Die vorliegende Erfindung betrifft einen Haartrockner mit einem Gebläse zur Erzeugung einer Warmluftströmung und mit einem Aufsatz gemäß dem Oberbegriff des Anspruchs 1. Die Erfindung betrifft des Weiteren einen derartigen Aufsatz für einen solchen Haartrockner.The present invention relates to a hair dryer with a fan for generating a warm air flow and with an attachment according to the preamble of claim 1. The invention further relates to such an attachment for such a hair dryer.

Haartrockner werden üblicherweise zum Trocknen von feuchten bzw. nassen Haaren verwendet. Die dabei erzeugte Warmluftströmung wird gewöhnlich mittels eines Gebläses erzeugt und über einen Aufsatz des Haartrockners ausgeblasen, wobei das Gebläse bzw. der Haartrockner zum Erwärmen der Luft entsprechende Bauteile, wie beispielsweise Heizelemente und dergleichen, aufweisen kann. Hierbei ist es prinzipiell möglich, besagten Aufsatz abnehmbar auszugestalten, derart dass unterschiedliche Aufsätze des Haartrockners für unterschiedliche Zwecke verwendet werden können. Hierzu ist es insbesondere wünschenswert, den Aufsatz während des Haartrocknens, das heißt während dem Betrieb des Haartrockners und/oder unmittelbar nach einem Abstellen des Haartrockners, austauschen zu können. Aus der WO 2008/015704 A1 ist beispielsweise ein Haartrockner mit einem Gebläse und einem Aufsatz bekannt, wobei der Aufsatz eine Außenwand und zumindest bereichsweise eine Innenwand aufweist, in welcher ein Haarbehandlungsmittel bevorratet ist und während des Betriebs des Haartrockners abgegeben werden kann. Zwischen der Innenwand und der Außenwand ist dabei ein Steg angeordnet. Ein derartiger Aufsatz für einen einfach zu transportierenden und kompakt geformten Haartrockner sind auch aus der WO 2012/019357 A1 und aus JP 2008 200429 A bekannt.Hair dryers are commonly used to dry damp or wet hair. The hot air flow generated thereby is usually generated by means of a fan and blown out via an attachment of the hair dryer, wherein the blower or the hair dryer for heating the air corresponding components, such as heating elements and the like may have. In this case, it is in principle possible to make said attachment removable, so that different attachments of the hair dryer can be used for different purposes. For this purpose, it is particularly desirable to be able to replace the attachment during hair drying, that is, during operation of the hair dryer and / or immediately after stopping the hair dryer. From the WO 2008/015704 A1 For example, a hair dryer with a fan and an attachment is known, wherein the attachment has an outer wall and at least partially an inner wall in which a hair treatment agent is stored and can be delivered during operation of the hair dryer. Between the inner wall and the outer wall while a web is arranged. Such an attachment for an easy to transport and compact shaped hair dryer are also from the WO 2012/019357 A1 and from JP 2008 200429 A known.

Nachteilig bei den bekannten Haartrocknern und Aufsätzen ist, dass der auf den Haartrockner aufgesetzte Aufsatz während des Betriebes des Haartrockners bedingt durch die Warmluftströmung, die eine Temperatur von ca. 100° C und mehr aufweisen kann, stark erwärmt wird. Der erhitzte Aufsatz kann folglich von einem Benutzer des Haartrockners während des Betriebes des Haartrockners bzw. kurz nach dem Abschalten des Haartrockners nicht gefahrlos und/oder nur unter Verwendung geeigneter Schutzmaßnahmen vom Haartrockner abgenommen werden, um beispielsweise den Aufsatz durch einen anderen Aufsatz zu ersetzen. Mitunter kann ein Kontakt des Benutzers mit dem Aufsatz während des Betriebes des Haartrockners oder unmittelbar nach dem Abschalten des Haartrockners zu Verbrennungen führen. Eine Alternative wäre eine nicht erwünschte Wartezeit, die nach dem Abschalten des Haartrockners erforderlich ist, bis sich der Aufsatz soweit abgekühlt hat, dass ein Berühren des Aufsatzes gefahrlos möglich ist.A disadvantage of the known hair dryers and essays that the patch on the hair dryer essay during operation of the hair dryer due to the warm air flow, which may have a temperature of about 100 ° C and more, is strongly heated. Consequently, the heated attachment can not be safely removed from the hair dryer by a user of the hair dryer during operation of the hair dryer or shortly after switching off the hair dryer and / or only with suitable protective measures, for example to replace the attachment with another attachment. Sometimes a contact of the User with the attachment during operation of the hair dryer or immediately after switching off the hair dryer burns. An alternative would be an undesirable waiting time, which is required after switching off the hair dryer until the essay has cooled down so far that a touch of the essay is safely possible.

Die vorliegende Erfindung beschäftigt sich mit dem Problem, für einen Haartrockner der eingangs genannten Art sowie dessen Aufsatz eine verbesserte oder zumindest alternative Ausführungsform anzugeben, die sich insbesondere durch eine verbesserte Handhabung auszeichnet.The present invention addresses the problem of providing a hair dryer of the type mentioned and its article an improved or at least alternative embodiment, which is characterized in particular by improved handling.

Dieses Problem wird erfindungsgemäß durch die Gegenstände der unabhängigen Ansprüche gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.This problem is solved according to the invention by the subject matters of the independent claims. Advantageous embodiments are the subject of the dependent claims.

Die vorliegende Erfindung beruht auf dem allgemeinen Gedanken, einen Aufsatz eines Haartrockners über den eine Warmluftströmung zum Trocknen von Haaren ausgeblasen wird, zumindest bereichsweise mehrwandig auszubilden, so dass eine von der Warmluftströmung entfernte Außenwand des mehrwandig ausgebildeten Aufsatzes einen reduzierten durch die Warmluftströmung bewirkten Temperaturanstieg aufweist und so auch im Betrieb vor einer zu starken Aufheizung geschützt wird. Damit kann der Aufsatz während des Betriebs des Haartrockners und/oder unmittelbar bzw. kurz nach Abschalten des Haartrockners vom Haartrockner abgenommen werden, ohne dass hierbei Verletzungen, insbesondere Verbrennungen und/oder ein unangenehmes Gefühl zu befürchten sind und/oder zusätzliche Mittel notwendig sind. Mehrwandig bedeutet vorliegend insbesondere, dass der Aufsatz im entsprechenden Bereich zumindest doppelwandig ausgebildet ist und somit zumindest zwei Wände aufweist. Der Haartrockner weist ein Gebläse zur Erzeugung der Warmluftströmung auf, die durch einen Innenraum des Aufsatzes strömt und über den Aufsatz ausgeblasen wird, wobei der Aufsatz abnehmbar ausgestaltet ist, so dass er vom Haartrockner abgenommen und/oder auf den Haartrockner aufgesetzt werden kann. Erfindungsgemäß ist der Aufsatz zumindest bereichsweise mehrwandig ausgestaltet. Das heißt, dass der Aufsatz zumindest bereichsweise eine Innenwand und die Außenwand aufweist, zwischen denen ein Zwischenraum des Aufsatzes ausgebildet bzw. angeordnet ist, so dass die Außenwand auch im Betrieb des Haartrockners vor einer zu starken Aufheizung geschützt ist. Dabei wird also insbesondere eine Wärmeübertragung von der Innenwand auf die Außenwand reduziert, wobei die Wärmeübertragung sowohl direkt bzw. mittelbar über einen Kontakt also auch kontaktlos, beispielsweise durch Wärmestrahlung, erfolgen kann. Hierbei ist die Innenwand der Warmluftströmung zugewandt und kann dementsprechend den Innenraum des Aufsatzes umgeben, während die Außenwand die von der Warmluftströmung abgewandte bzw. entfernte äußere Wand des Aufsatzes ist, die zusammen mit der Innenwand den Zwischenraum des Aufsatzes umgibt. Bei Ausgestaltungen des Aufsatzes mit mehr als zwei Wänden kann also zwischen der Innenwand und der Außenwand zumindest eine Zwischenwand angeordnet sein, die somit im Zwischenraum angeordnet ist. Der Zwischenraum ist dabei insbesondere ein vom Innenraum unterschiedlicher Raum, beispielsweise ein Hohlraum. Bei einem nur bereichsweise mehwandig ausgestalteten Aufsatz sind bevorzugt diejenigen Bereiche des Aufsatzes mehrwandig ausgestaltet, die während des Betriebes des Haartrockners eine vergleichsweise hohe Temperatur aufweisen und/oder zum Abnehmen des Aufsatzes durch einen Benutzer berührt werden.The present invention is based on the general idea of an attachment of a hair dryer over which a hot air flow is blown for drying hair, at least partially multi-wall form, so that a remote from the warm air flow outer wall of the multi-walled essay has a reduced caused by the hot air flow temperature increase and so it is protected in the factory from excessive heating. Thus, the article can be removed from the hair dryer during operation of the hair dryer and / or immediately or shortly after switching off the hair dryer, without this injury, especially burns and / or an unpleasant feeling are to be feared and / or additional funds are necessary. In the present case, multi-walled means in particular that the attachment is designed to be at least double-walled in the corresponding area and thus has at least two walls. The hair dryer has a fan for generating the hot air flow, which flows through an interior of the essay and is blown over the attachment, wherein the attachment is designed to be removable so that it can be removed from the hair dryer and / or placed on the hair dryer. According to the invention, the attachment is at least partially multi-walled. This means that the attachment at least partially has an inner wall and the outer wall, between which a gap of the attachment is formed or arranged, so that the Outside wall is protected in the operation of the hair dryer from excessive heating. In this case, in particular a heat transfer from the inner wall is reduced to the outer wall, wherein the heat transfer both directly or indirectly via a contact so contactless, for example by thermal radiation, can be done. Here, the inner wall of the hot air flow is facing and can accordingly surround the interior of the essay, while the outer wall is remote from the hot air flow or remote outer wall of the essay, which surrounds the space of the essay together with the inner wall. In embodiments of the article with more than two walls can thus be arranged between the inner wall and the outer wall at least one intermediate wall, which is thus arranged in the intermediate space. The intermediate space is in particular a space different from the interior, for example a cavity. In the case of an attachment which is only of a multimode design, those regions of the attachment are preferably multi-walled, which have a comparatively high temperature during operation of the hair dryer and / or are touched by a user to remove the attachment.

Bevorzugt sind wenigstens zwei der Wände des Aufsatzes voneinander beabstandet angeordnet. Das heißt insbesondere, dass die Innenwand und die Außenwand zumindest bereichsweise voneinander beabstandet angeordnet sind. Dies hat insbesondere den Vorteil, dass die Wärme der von der Warmluftströmung erwärmten bzw. erhitzten Innenwand in diesem Bereich nicht unmittelbar, das heißt durch direkten Kontakt, auf die Außenwand übertragbar ist.Preferably, at least two of the walls of the attachment are spaced from each other. This means in particular that the inner wall and the outer wall are at least partially spaced from each other. This has the particular advantage that the heat of the heated or heated by the hot air flow inside wall in this area is not directly, that is, by direct contact, transferable to the outer wall.

Nachfolgend wird der Einfachheit halber lediglich auf eine zumindest bereichsweise doppelwandige Ausführungsform des Aufsatzes eingegangen. Es versteht sich jedoch, dass die nachfolgenden Erläuterungen analog auf Ausführungsformen des Haartrockners mit einem solchen Aufsatz mit mehr als zwei Wänden übertragbar sind und dass diese ebenfalls zum Umfang dieser Erfindung gehören.Hereinafter, for the sake of simplicity, only an at least partially double-walled embodiment of the article will be discussed. It is understood, however, that the following explanations analogously to embodiments of the hair dryer with such an essay with more than two walls are transferable and that these also belong to the scope of this invention.

Zur beabstandeten Anordnung der Innenwand von der Außenwand kommen insbesondere Stege zum Einsatz. Erfindungsgemäß kommt dazu zumindest ein solcher Steg zum Einsatz. Durch die zumindest bereichsweise beabstandete Anordnung der Innenwand von der Außenwand ist es insbesondere möglich, zwischen der Innenwand und der Außenwand einen Hohlraum auszubilden, welcher insbesondere die besagte unmittelbare Wärmeübertragung zwischen der Innenwand und der Außenwand verhindert oder zumindest reduziert. Dabei kann dieser Hohlraum dem Zwischenraum des Aufsatzes entsprechen. In besagtem Hohlraum kann hierzu insbesondere ein Unterdruck, insbesondere vakuumähnliche Verhältnisse, herrschen. Vorstellbar ist es auch, besagten Hohlraum mit einem die Wärmeübertragung reduzierenden Fluid, also insbesondere einem Gas wie beispielsweise Luft, Argon sowie Krypton und dergleichen, zu füllen.For spaced arrangement of the inner wall of the outer wall in particular webs are used. According to the invention, at least one such web is used for this purpose. Due to the at least partially spaced arrangement of the inner wall of the outer wall, it is particularly possible between the inner wall and form the outer wall of a cavity, which in particular prevents or at least reduces the said direct heat transfer between the inner wall and the outer wall. In this case, this cavity correspond to the gap of the essay. In particular, a vacuum, in particular vacuum-like conditions, prevail in said cavity. It is also conceivable to fill said cavity with a fluid which reduces the heat transfer, that is to say in particular a gas such as, for example, air, argon and krypton and the like.

Erfindungsgemäß ist zwischen der Innenwand und der Außenwand ein Strömungskanal ausgebildet. Dieser Strömungskanal kann insbesondere durch einen solchen zwischen der Innenwand und der Außenwand ausgebildeten Hohlraum und/oder durch den Zwischenraum des Aufsatzes ausgebildet sein. Der Strömungskanal dient insbesondere dem Zweck, eine Strömung in dem Zwischenraum bzw. dem Hohlraum zu ermöglichen, wobei es sich bei der Strömung beispielsweise um Luftströmung handelt. Dabei ist der Strömungskanal erfindungsgemäß eingangsseitig, das heißt in einem von einer Auslassöffnung des Aufsatzes entfernten Bereich, mit der Umgebung verbunden. Durch eine derartige Verbindung mit der Umgebung kann Umgebungsluft in den Strömungskanal gelangen, was insbesondere die Wärmeübertragung der Innenwand auf die Außenwand reduziert. Bevorzugt ist der Strömungskanal zudem ausgangsseitig, das heißt im Bereich der Auslassöffnung, zusätzlich mit der Umgebung verbunden. Hierdurch wird durch die ausgangsseitig des Aufsatzes ausströmende Warmluftströmung ein Sog innerhalb des Strömungskanales erzeugt, derart, dass Umgebungsluft eingangsseitig in den Strömungskanal eingesaugt wird und ausgangsseitig aus dem Strömungskanal hinausströmt. Somit wird also eine Luftströmung innerhalb des Strömungskanales erzeugt, welche die Wärmeübertragung der Innenwand auf die Außenwand reduziert und/oder die Außenwand kühlt.According to the invention, a flow channel is formed between the inner wall and the outer wall. This flow channel can be formed in particular by such a cavity formed between the inner wall and the outer wall and / or by the intermediate space of the attachment. In particular, the flow channel serves the purpose of allowing a flow in the intermediate space or the cavity, wherein the flow is, for example, air flow. In this case, according to the invention, the flow channel is connected on the input side, that is to say in an area remote from an outlet opening of the attachment, to the environment. By such a connection with the environment ambient air can enter the flow channel, which in particular reduces the heat transfer of the inner wall to the outer wall. Preferably, the flow channel is also the output side, that is, in the region of the outlet, additionally connected to the environment. As a result, a suction is generated within the flow channel through the output side of the essay flowing out hot air flow, such that ambient air is sucked in on the input side into the flow channel and the output side flows out of the flow channel. Thus, an air flow is thus generated within the flow channel, which reduces the heat transfer of the inner wall to the outer wall and / or cools the outer wall.

Zur Verbesserung besagter Strömung innerhalb des Strömungskanales, insbesondere zur Erhöhung der Strömungsgeschwindigkeit, kann der Strömungskanal eingangsseitig zusätzlich mit der vom Gebläse erzeugten Warmluftströmung verbunden sein bzw. das Einströmen eines gewissen, vorzugsweise geringen, Anteils der Warmluftströmung in den Strömungskanal erlauben. Hierdurch strömt ein Teil der Warmluftströmung in den Strömungskanal, wodurch die Strömung innerhalb des Strömungskanales von der Eingangsseite hin zur Ausgangsseite erhöht wird.To improve said flow within the flow channel, in particular to increase the flow velocity, the flow channel on the input side can be additionally connected to the hot air flow generated by the fan or allow the inflow of a certain, preferably low, proportion of hot air flow into the flow channel. As a result, a portion of the hot air flow flows into the flow channel, whereby the flow is increased within the flow channel from the input side to the output side.

Der Strömungskanal zwischen der Innenwand und der Außenwand kann, wie vorstehend erwähnt, insbesondere mit Hilfe zumindest eines solchen Steges ausgebildet sein. Hierbei kann der Steg derart ausgestaltet und/oder angeordnet sein, dass er die Strömung innerhalb des Strömungskanales möglichst gezielt beeinflusst. So ist erfindungsgemäß zumindest ein solcher Steg als Strömungsleitelement ausgebildet bzw. ausgestaltet und derart geformt und/oder derart innerhalb des Strömungskanales angeordnet, dass hierdurch eine gezielte Umlenkung der Strömung innerhalb des Strömungskanales bewirkt wird. Dies kann beispielsweise derart realisiert sein, dass hierdurch der Strömungsweg innerhalb des Strömungskanales verlängert wird, um insbesondere eine verbesserte Kühlung der Außenwand zu erreichen.The flow channel between the inner wall and the outer wall may, as mentioned above, be formed in particular by means of at least one such web. In this case, the web can be designed and / or arranged such that it influences the flow within the flow channel as specifically as possible. Thus, according to the invention, at least one such web is designed or configured as a flow-guiding element and shaped and / or arranged within the flow channel in such a way that a targeted deflection of the flow within the flow channel is effected. This can be realized, for example, such that in this way the flow path within the flow channel is lengthened in order in particular to achieve improved cooling of the outer wall.

Durch die Verbindung der Innenwand und der Außenwand mittels eines solchen Steges kann jedoch eine Wärmeübertragung zwischen der Innenwand und der Außenwand über den zumindest einen Steg erfolgen. Dabei ist der Haartrockner bzw. der Aufsatz, insbesondere mittels des Strömungskanals, derart ausgestaltet, dass auch diese Bereiche der Außenwand ausreichend gekühlt sind und/oder dass diese Bereiche der Wand ein gefahrloses Anfassen erlauben. Um eine Berührung mit der Außenwand in diesen Bereichen zu verhindern und/oder die Temperatur in diesen Bereichen zusätzlich zu verringern, kann die Außenwand im Bereich eines solchen Steges eine Markierung aufweisen. Die Markierung kann optisch, beispielsweise in Form einer Färbung, realisiert sein, die dem Benutzer signalisiert, dass dieser Bereich des Aufsatzes eine im Vergleich zu anderen Bereichen des Aufsatzes erhöhte Temperatur aufweist. Auch ist es vorstellbar, einen solchen Bereich alternativ oder zusätzlich mit einer haptischen Markierung zu versehen, wobei die haptische Markierung zusätzlich oder alternativ zur besagten Hinweisfunktion eine reduzierte Temperatur im jeweiligen Bereich bewirken kann. Eine derartige haptische Markierung ist beispielsweise mittels einer Beflockung herstellbar. Auch ist es vorstellbar eine derartige haptische Markierung als eine von der Außenwand beabstandete Wandung auszugestalten.By connecting the inner wall and the outer wall by means of such a web, however, a heat transfer between the inner wall and the outer wall via the at least one web can take place. In this case, the hair dryer or the attachment, in particular by means of the flow channel, designed such that these areas of the outer wall are sufficiently cooled and / or that these areas of the wall allow a safe hands. In order to prevent contact with the outer wall in these areas and / or to additionally reduce the temperature in these areas, the outer wall can have a marking in the region of such a bar. The marking can be realized optically, for example in the form of a coloring, which signals to the user that this area of the attachment has an elevated temperature compared to other areas of the attachment. It is also conceivable to provide such a region alternatively or additionally with a haptic marking, wherein the haptic marking in addition to or as an alternative to said indication function can bring about a reduced temperature in the respective region. Such a haptic marking can be produced for example by means of flocking. It is also conceivable to design such a haptic marking as a wall spaced from the outer wall.

Prinzipiell kann der abnehmbare Aufsatz beliebig ausgestaltet und/oder ausgebildet sein. Es sind insbesondere Ausgestaltungen vorstellbar, bei denen der Aufsatz als Düse, Ondulierdüse bzw. als Diffusor oder eine Mischung daraus ausgebildet ist.In principle, the removable attachment can be configured and / or designed as desired. In particular, embodiments are conceivable in which the attachment is designed as a nozzle, an ondulier nozzle or as a diffuser or a mixture thereof.

Entsprechend Fig. 1 weist ein Haartrockner 1 ein Gehäuse 2 auf, in dem ein Gebläse 3 angeordnet ist. Stromauf des Gebläses 3, das beispielsweise als Ventilator ausgestaltet sein kann, weist das Gehäuse 2 mehrere Lufteingangsöffnungen 4 auf, um Luft aus der Umgebung mittels des Gebläses 3 einzusaugen und über einen Aufsatz 5 des Haartrockners 1 auszublasen. Hierbei ist stromauf bzw. stromab des Gebläses 3 zumindest ein nicht gezeigtes und im Folgenden nicht weiter bezeichnetes Heizelement angeordnet, um somit mittels des Gebläses 3 eine Warmluftströmung 6 zu erzeugen, die aus einer Auslassöffnung 7 des Aufsatzes 5 ausgeblasen wird. Der Aufsatz 5 ist abnehmbar auf einen Warmluftkanal 8 des Haartrockners 1 aufgesetzt, von dem ein Griff 9 absteht, über dessen vom Gebläse 3 entfernten Ende eine elektrischer Anschluss zur Versorgung der elektrischen Bestandteile des Haartrockners 1, also insbesondere des Gebläses 3 und des Heizelementes, realisiert ist.Corresponding Fig. 1 For example, a hair dryer 1 has a housing 2 in which a blower 3 is arranged. Upstream of the blower 3, which may be configured for example as a fan, the housing 2 has a plurality of air inlet openings 4 to suck in air from the environment by means of the blower 3 and blow through an attachment 5 of the hair dryer 1. Here, upstream or downstream of the blower 3, at least one not shown and not further designated hereinafter heating element arranged so as to produce by means of the blower 3, a hot air flow 6, which is blown out of an outlet opening 7 of the attachment 5. The attachment 5 is detachably mounted on a hot air duct 8 of the hair dryer 1, projects from which a handle 9, on the end remote from the fan 3, an electrical connection for supplying the electrical components of the hair dryer 1, ie in particular the blower 3 and the heating element implemented is.

Fig. 2 zeigt einen Längsschnitt entlang des Warmluftkanals 8 des Haartrockners 1 im Bereich des Aufsatzes 5. Darin ist zu erkennen, dass der Aufsatz 5 mehrwandig ausgebildet ist, wobei der Aufsatz bei der gezeigten Ausführungsform zwei Wände 10, 11 aufweist und somit doppelwandig ausgebildet ist. Der Aufsatz 5 weist eine der Warmluftströmung 6 zugewandte bzw. benachbarte Innenwand 10 sowie eine von der Warmluftströmung 6 abgewandte bzw. entfernte Außenwand 11 auf. Somit umgibt die Innenwand 10 einen Innenraum 25 des Aufsatzes, durch den die Warmluftströmung 6 strömt und aus der Auslassöffnung 7 ausgeblasen wird. Ferner umgeben die Innenwand 10 und die Außenwand 11 einen vom Innenraum 25 entfernten Zwischenraum 26 des Aufsatzes 5. Hierbei sind die Innenwand 10 und die Außenwand 11 voneinander beabstandet angeordnet und mittels zumindest eines Steges 12 miteinander verbunden, wobei im gezeigten Beispiel zwei solche Stege 12 dargestellt sind. Durch die beabstandete Anordnung der Innenwand 10 und der Außenwand 11 und bedingt durch den Zwischenraum 26 entsteht zwischen der Innenwand 10 und der Außenwand 11 ein Strömungskanal 13, der eingangsseitig, das heißt auf der dem Warmluftkanal 8 zugewandten Seite, mit der Umgebung 14 verbunden ist. Zudem ist der Strömungskanal 13 auch ausgangsseitig, das heißt im Bereich der Auslassöffnung 7, mit der Umgebung 14 verbunden, so dass hier eine Luftströmung innerhalb des Strömungskanals 13 möglich ist. Hierbei strömt die aus der Umgebung 14 stammende Umgebungsluft 15 über die eingangsseitige Verbindung in den Strömungskanal 13 ein und durchströmt den Strömungskanal 13, um anschließend über die ausgangsseitige Verbindung mit der Umgebung 14 aus dem Strömungskanal 13 auszuströmen. Besagte Strömung ist insbesondere dadurch bedingt, dass die aus der Auslassöffnung 7 hinausströmende Warmluftströmung 6 einen Sog im Bereich der auslassseitigen Verbindung des Strömungskanals 13 erzeugt. Fig. 2 shows a longitudinal section along the hot air duct 8 of the hair dryer 1 in the region of the article 5. It can be seen that the article 5 is formed mehrwandig, wherein the article in the embodiment shown two walls 10, 11 and thus is double-walled. The attachment 5 has a warm air flow 6 facing or adjacent inner wall 10 and a remote from the warm air flow 6 or removed outer wall 11. Thus, the inner wall 10 surrounds an inner space 25 of the attachment, through which the warm air flow 6 flows and is blown out of the outlet opening 7. Furthermore, the inner wall 10 and the outer wall 11 surround a space 26 of the attachment 5 which is remote from the inner space 25. The inner wall 10 and the outer wall 11 are arranged at a distance from each other and connected to one another by means of at least one web 12, two such webs 12 being shown in the example shown are. Due to the spaced arrangement of the inner wall 10 and the outer wall 11 and due to the gap 26 is formed between the inner wall 10 and the outer wall 11, a flow channel 13, the input side, that is on the hot air channel 8 side facing the environment 14 is connected. In addition, the flow channel 13 is also connected on the output side, that is to say in the region of the outlet opening 7, to the environment 14, so that an air flow within the flow channel 13 is possible here. In this case, the ambient air 15 originating from the environment 14 flows into the flow channel 13 via the inlet-side connection and flows through it Flow channel 13 to then flow out via the output-side connection with the environment 14 from the flow channel 13. Said flow is due in particular to the fact that the hot air flow 6 flowing out of the outlet opening 7 generates a suction in the region of the outlet-side connection of the flow channel 13.

Um die Strömung innerhalb des Strömungskanals 13 zu verbessern ist der Strömungskanal 13 zusätzlich eingangsseitig mit der Warmluftströmung 6 bzw. dem Warmluftkanal 8 derart verbunden, dass ein Teil der Warmluftströmung 6 eingangsseitig des Strömungskanales 13 in diesen gelangt. Hier wird die in den Strömungskanal 13 gelangende Warmluftströmung 6 mit der durch die eingangsseitig in den Strömungskanal 13 gelangenden Umgebungsluft 15 vermischt, wodurch die Warmluftströmung 6 abgekühlt wird und eine Mischströmung 16 durch den Strömungskanal 13 strömt. Durch das Strömen der Warmluftströmung 6 in den Strömungskanal 13 und/oder durch besagte Durchmischung entsteht hierbei eine erhöhte Strömungsgeschwindigkeit innerhalb des Strömungskanales 13, so dass dadurch auch der Strömungsdurchsatz durch den Strömungskanal 13 erhöht wird. Somit wird mittels der aus der Mischung der Warmluftströmung 6 und der Umgebungsluft 15 durch den Strömungskanal 13 strömenden Mischströmung 16 eine verbesserte Kühlung der Außenwand 11 erreicht. Hierbei versteht es sich, dass der jeweilige Steg 12 in Umfangsrichtung nicht geschlossen verläuft, um eine fluidische Verbindung der eingangsseitigen Verbindungen des Strömungskanales 13 mit der ausgangsseitigen Verbindung des Strömungskanales 13 zu gewährleisten.In order to improve the flow within the flow channel 13, the flow channel 13 is additionally connected on the input side with the hot air flow 6 and the hot air duct 8 such that a part of the hot air flow 6 enters the input side of the flow channel 13 in this. Here, the hot air flow 6 reaching into the flow channel 13 is mixed with the ambient air 15 passing through the input side into the flow channel 13, whereby the warm air flow 6 is cooled and a mixed flow 16 flows through the flow channel 13. By the flow of hot air flow 6 into the flow channel 13 and / or by said mixing creates an increased flow velocity within the flow channel 13, thereby also increasing the flow rate through the flow channel 13. Thus, an improved cooling of the outer wall 11 is achieved by means of the mixed flow 16 flowing from the mixture of the warm air flow 6 and the ambient air 15 through the flow channel 13. It is understood that the respective web 12 is not closed in the circumferential direction in order to ensure a fluidic connection of the inlet-side connections of the flow channel 13 with the outlet-side connection of the flow channel 13.

Der Fig. 2 ist ferner zu entnehmen, dass sich die Stege 12 entlang der im Strömungskanal 13 strömenden Strömung, das heißt also insbesondere entlang der Mischströmung 16 sowie der Warmluftströmung 6 und der Umgebungsluft 15 erstrecken, um eine möglichst ungehinderte Strömung durch den Strömungskanal 13 zu gewährleisten.Of the Fig. 2 Furthermore, it can be seen that the webs 12 extend along the flow flowing in the flow channel 13, that is to say in particular along the mixed flow 16 and the hot air flow 6 and the ambient air 15, in order to ensure a flow through the flow channel 13 that is as unhindered as possible.

Fig. 3 zeigt eine andere Ausführungsform des Haartrockners 1 bzw. des Aufsatzes 5. Bei dieser Ausgestaltung sind die Stege 12 als Strömungsleitelemente 17 ausgestaltet, die eine gezielte Umlenkung der Strömung innerhalb des Strömungskanals 13 bewirken, um beispielsweise den Strömungsweg innerhalb des Strömungskanales 13 zu verlängern. Des Weiteren ist der Strömungskanal 13 eingangsseitig lediglich mit der Umgebung 14 und nicht mit dem Warmluftkanal 8 verbunden. Zudem weist die Außenwand 11 auf seiner von der Innenwand 10 abgewandten Seite im Bereich des jeweiligen Steges 12 eine Markierung 18 auf, die dem Zweck dient, einen Benutzer darauf hinzuweisen, dass in diesen Bereichen eine erhöhte Temperatur herrschen kann. Alternativ oder zusätzlich kann die Markierung 18 dem Zweck dienen, besagte erhöhte Temperatur in diesen Bereichen zu reduzieren. Die Markierung 18 ist hierbei optisch und haptisch realisiert, wobei die optische Ausgestaltung mittels einer entsprechenden Färbung 19 der jeweiligen Markierung 18 realisiert ist. Die haptische Ausgestaltung der jeweiligen Markierung 18 ist dadurch bewirkt, dass die Markierung 18 zumindest bereichsweise von der Außenwand 11 beabstandet angeordnet ist, wodurch auch besagte reduzierte Temperaturübertragung bewirkt wird. Hierbei kann die jeweilige Markierung 18 als eine Wandung 20 und/oder als eine Beflockung 21 ausgestaltet sein. Fig. 3 shows another embodiment of the hair dryer 1 and the attachment 5. In this embodiment, the webs 12 are designed as flow guide 17, which cause a targeted deflection of the flow within the flow channel 13, for example, to extend the flow path within the flow channel 13. Furthermore, the flow channel 13 on the input side only with the environment 14th and not connected to the warm air duct 8. In addition, the outer wall 11 on its side facing away from the inner wall 10 side in the region of the respective web 12, a mark 18, which serves the purpose of informing a user that can prevail in these areas, an elevated temperature. Alternatively or additionally, the mark 18 may serve the purpose of reducing said elevated temperature in these areas. The marking 18 is in this case realized optically and haptically, wherein the optical configuration is realized by means of a corresponding coloring 19 of the respective marking 18. The haptic configuration of the respective marking 18 is effected in that the marking 18 is arranged at least partially spaced from the outer wall 11, whereby said reduced temperature transfer is effected. In this case, the respective marking 18 can be designed as a wall 20 and / or as a flock 21.

Der Aufsatz 5 kann bei der erfindungsgemäßen Lösung beliebig ausgestaltet sein. Der Aufsatz 5 kann insbesondere als Düse 22, Ondulierdüse 23 oder Diffusor 24 ausgebildet sein.The article 5 can be configured as desired in the inventive solution. The attachment 5 may be formed in particular as a nozzle 22, 23 Ondulierdüse or diffuser 24.
