Description

Die vorliegende Erfindung betrifft einen Diffusor eines Haartrockners gemäß Anspruch 1.The present invention relates to a diffuser of a hair dryer according to claim 1.

Die Erfindung betrifft außerdem einen mit einem derartigen Diffusor ausgestatteten Haartrockner.The invention also relates to a hair dryer equipped with such a diffuser.

Diffusoren für Haartrockner sind hinlänglich bekannt und dienen üblicherweise zu einem gleichmäßigen Trocknen von insbesondere gelockten bzw. gewellten Haaren. Generell gibt es dabei zwei Prinzipien von Diffusoren, nämlich einerseits einen mit langen Fingern, die gegebenenfalls seitlich gelocht sind und andererseits eine Schüssel, die nach oben gerichtet von unten an das zu trocknende Haar herangeführt wird. Beide Prinzipien beruhen dabei auf einem Luftstrom, der den Diffusor in im Wesentlichen gleicher Richtung verlässt, wie er von einem Haartrockner in den Diffusor eingeblasen wird. Die aus dem Stand der Technik bekannten Diffusoren weisen dabei jedoch den Nachteil auf, dass zu wenig der trockenen Luft durch die Haare geleitet oder letztere gar von der trocknenden Luft aus dem Diffusor herausgeblasen werden und dadurch nur ein unbefriedigendes Trocknen erreicht werden kann.Hair dryer diffusers are well known and usually serve to uniformly dry curly or wavy hair in particular. In general, there are two principles of diffusers, namely on the one hand with long fingers, which are optionally perforated laterally and on the other hand, a bowl, which is directed upward from below to the hair to be dried. Both principles are based on a flow of air leaving the diffuser in substantially the same direction as it is blown into the diffuser by a hair dryer. However, the known from the prior art diffusers have the disadvantage that too little of the dry air passed through the hair or the latter are even blown out of the drying air from the diffuser and thus only an unsatisfactory drying can be achieved.

Die US 5 956 863 A betrifft das Gebiet von tragbaren Haartrocknern von dem Typ, der die Druckluft für verbesserte Trocknungsbedingungen auf einen gemeinsamen Punkt konzentriert.The US 5 956 863 A relates to the field of portable hair dryers of the type that concentrates the compressed air to a common point for improved drying conditions.

Die US 1 637 035 A beschreibt ein Standgerät zum Trocknen von Haaren und Kopfhaut.The US 1 637 035 A describes a free-standing device for drying hair and scalp.

Die DE 23 48 314 A1 bezieht sich auf ein Haartrocknungsgerät, bestehend aus einem äußeren, schalenförmigen Gehäuse, einem in dem Gehäuse angeordneten Gebläse, einer Ansaugöffnung für das Gebläse und einer Leiteinrichtung, wobei Gehäuse, Gebläse und Leiteinrichtung eine solche geometrische Konfiguration aufweisen, daß der aus dem Gebläse austretende Luftstrom in den Raum zwischen Gehäuse und Leiteinrichtung eintritt, und daß zwischen Gehäuse und Leiteinrichtung ein am Außenrand des Haartrocknungsgeräts liegender geschlossener Luftaustrittsschlitz gebildet wird, wobei im Strömungsweg der Luft eine Heizeinrichtung angeordnet ist.The DE 23 48 314 A1 relates to a hair dryer, consisting of an outer, shell-shaped housing, a fan arranged in the housing, a suction opening for the fan and a guide, wherein housing, fan and guide have such a geometric configuration that the air flow exiting the fan in enters the space between the housing and the guide, and that between the housing and guide a lying on the outer edge of the hair dryer closed air outlet slot is formed, wherein a heating device is arranged in the flow path of the air.

Das Dokument JPS51147694U offenbart den Gegenstand des Oberbegriffs des Anspruchs 1.The document JPS51147694U discloses the subject matter of the preamble of claim 1.

Die vorliegende Erfindung beschäftigt sich mit dem Problem, für einen Diffusor der gattungsgemäßen Art eine verbesserte oder zumindest eine alternative Ausführungsform anzugeben, die sich insbesondere durch eine verbesserte Trocknung und weitere, mit bisherigen Diffusoren nicht erzielbare Effekte auszeichnet.The present invention addresses the problem of providing a diffuser of the generic type an improved or at least one alternative embodiment, which is characterized in particular by an improved drying and other, not achievable with previous diffusers effects.

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 in den Diffusor mittels eines Haartrockners eingeleiteten Luftstrom derart mittels des Diffusors umzulenken, dass die zu trocknenden Haare auf einen Boden des Diffusors gedrückt/gezogen werden, wobei der Luftstrom durch dort angeordnete, bodenseitige Luftauslassöffnungen entweicht. Der erfindungsgemäße Diffusor besitzt somit bodenseitige, dem Haartrockner zugewandte Luftauslassöffnungen und ist derart ausgebildet, dass beim Betrieb des Haartrockners eine in dem Diffusor zirkulierende, das heißt kreisende, Luftströmung erzeugt wird, die die Haare in den Diffusor einsaugt und die den Diffusor im Wesentlichen, das heißt üblicherweise überwiegend, über die bodenseitigen Luftauslassöffnungen wieder verlässt. Mit dem erfindungsgemäßen Diffusor kann somit erreicht werden, dass der vom Haartrockner erzeugte trockene Luftstrom effizient zum Trocknen der Haare genutzt werden kann, da die Haare nicht wie bisher bei bekannten Diffusoren von letzterem weggeblasen werden, sondern vielmehr in diesen eingesaugt und vom dort zirkulierenden trocknen Luftstrom getrocknet werden. Die Trocknungsfähigkeit eines mit dem erfindungsgemäßen Diffusor ausgestatteten Haartrockners ist dabei gängigen Diffusoren weit überlegen.The present invention is based on the general idea of redirecting an air stream introduced into the diffuser by means of a hair dryer by means of the diffuser in such a way that the hairs to be dried are pushed / pulled onto a bottom of the diffuser, the air flow escaping through bottom-side air outlet openings arranged there. The diffuser according to the invention thus has bottom-side, the hair dryer facing air outlet and is designed so that during operation of the hair dryer circulating in the diffuser, that is circular, air flow is generated, which sucks the hair in the diffuser and the diffuser essentially, the is usually called predominantly leaves on the bottom air outlet openings again. With the diffuser according to the invention can thus be achieved that the dry air stream generated by the hair dryer can be efficiently used for drying the hair, since the hair is not blown away as before in known diffusers of the latter, but rather sucked into this and circulating from the dry air stream be dried. The drying ability of a hair dryer equipped with the diffuser according to the invention is far superior to conventional diffusers.

Erfindungsgemäß, weist der Diffusor eine luftdurchströmte Außenschale und einen zentralen, ebenfalls luftdurchströmten Pilz auf, wobei an der Außenschale und/oder am Pilz Luftdüsen angeordnet sind, die zum Boden des Diffusors gerichtet sind und die die im Diffusor zirkulierende Luftströmung erzeugen. Die Benutzerin des Diffusors kann somit durch ein einfaches Einlegen Eigenlocken stärker herausarbeiten und wegen des im Diffusor zirkulierenden Luftstroms in feuchte Haare auch Locken einarbeiten, in dem Haare in gewirbelter Form getrocknet werden. Durch die rückwärts gewandten Luftdüsen an der Außenschale und/oder am Pilz wird auch ein Ansaugeffekt des Diffusors erzeugt, der die zu trocknenden Haare in den Zwischenraum zwischen der Außenschale und dem zentralen Pilz einzieht und dort trocknet. Die Luftdüsen können darüber hinaus derart gerichtet sein, dass die von diesen erzeugte Luftströmung nicht ausschließlich eine einfache Kreisströmung ist, sondern zusätzlich spiralförmig verdrillt wird. Eine derartig verdrillte Luftströmung unterstützt die Lockenbildung zusätzlich.According to the invention, the diffuser has an outer shell which is flowed through by air and a central mushroom which also flows through air, wherein air nozzles are arranged on the outer shell and / or on the mushroom, which nozzles are directed towards the bottom of the diffuser and which generate the air flow circulating in the diffuser. The user of the diffuser can thus work out more easily by simply inserting own curls and, because of the air flow circulating in the diffuser, into wet hair and also curls, in which hairs are dried in a swirled form. The backward-facing air nozzles on the outer shell and / or the mushroom also create a suction effect of the diffuser, which feeds the hair to be dried into the space between the outer shell and the central fungus and dries there. The air nozzles can also be directed in such a way that the air flow generated by them is not exclusively a simple circular flow, but is additionally spirally twisted. Such a twisted air flow additionally supports curling.

Zweckmäßig sind die Luftauslassöffnungen am Boden der Auslassschale, das heißt am Boden des Diffusors, mit einem luftdurchlässigen Gitter belegt. Dieses bewirkt, dass zwar Luft durch die vergitterten Luftauslassöffnungen ausströmen kann, mitgerissene Haare jedoch zurückgefallen werden und nicht mittels des Luftstroms unkontrolliert verteilt werden. Die ausgefallenen Haare sammeln sich vielmehr am Boden und insbesondere im Bereich der vergitterten Luftauslassöffnungen und können bei entsprechenden turnusmäßigen Reinigungsarbeiten am Diffusor einfach aus diesem entnommen werden. Das Vergittern der bodenseitigen Luftauslassöffnungen erhöht somit den Hygienestandard.Suitably, the air outlet at the bottom of the outlet shell, that is occupied at the bottom of the diffuser, with an air-permeable grid. This causes air to flow through the barred air outlet openings, but entrained hair can be dropped back and not distributed uncontrollably by the air flow. Rather, the failed hairs accumulate on the floor and in particular in the area of the barred air outlet openings and can easily be removed from the diffuser during regular cleaning work on the diffuser. The lattice of the bottom-side air outlet thus increases the standard of hygiene.

Weitere wichtige Merkmale und Vorteile der Erfindung ergeben sich aus den Unteransprüchen, aus den Zeichnungen und aus der zugehörigen Figurenbeschreibung anhand der Zeichnungen.Other important features and advantages of the invention will become apparent from the dependent claims, from the drawings and from the associated figure description with reference to the drawings.

Es versteht sich, dass die vorstehend genannten und die nachstehend noch zu erläuternden Merkmale nicht nur in der jeweils angegebenen Kombination, sondern auch in anderen Kombinationen oder in Alleinstellung verwendbar sind, ohne den Rahmen der vorliegenden Erfindung zu verlassen, solange sie sich im Rahmen der Ansprüche bewegen.It is understood that the features mentioned above and those yet to be explained not only in the particular combination given, but also in other combinations or alone, without departing from the scope of the present invention, as long as they are within the scope of the claims move.

Bevorzugte Ausführungsbeispiele der Erfindung sind in den Zeichnungen dargestellt und wird in der nachfolgenden Beschreibung näher erläutert, wobei sich gleiche Bezugszeichen auf gleiche oder ähnliche oder funktional gleiche Bauteile beziehen.Preferred embodiments of the invention are illustrated in the drawings and will be described in more detail in the following description, wherein like reference numerals refer to the same or similar or functionally identical components.

Entsprechend den Fig. 1 und 2, weist ein erfindungsgemäßer Diffusor 1 für einen Haartrockner 2 (vgl. Fig. 2) bodenseitige, dem Haartrockner 2 zugewandte Luftauslassöffnungen 3 auf und ist derart ausgebildet, dass beim Betrieb des Haartrockners 2 eine in dem Diffusor 1 kreisende, das heißt zirkulierende Luftströmung 4 erzeugt wird, die Haare 5 in den Diffusor 1 einsaugt und die den Diffusor 1 im Wesentlichen über die bodenseitigen Luftauslassöffnungen 3 wieder verlässt.According to the Fig. 1 and 2 , Has a diffuser 1 according to the invention for a hair dryer 2 (see. Fig. 2 ) on the bottom side, the hair dryer 2 facing air outlet 3 and is designed such that during operation of the hair dryer 2 a circulating in the diffuser 1, that is circulating air flow 4 is generated, the hair 5 is sucked into the diffuser 1 and the diffuser 1 im Leaves substantially on the bottom air outlet openings 3 again.

Der Diffusor 1 weist dabei eine luftdurchströmte Außenschale 6 und einen zentrale, ebenfalls luftdurchströmten Pilz 7 auf. An der Außenschale 6 und/oder am Pilz 7 sind dabei Luftdüsen 8 angeordnet, die zum Boden des Diffusors 1 gerichtet sind und die die im Diffusor 1 zirkulierende Luftströmung 4 bewirken. Im Wesentlichen sind dabei die Luftdüsen 8 zumindest am Pilz 7 rückwärts gewandt, das heißt einem ursprünglichen, in den Diffusor 1 von Haartrockner 2 eingeblasenen Luftstrom 4' (vgl. Fig. 2) entgegengerichtet.The diffuser 1 in this case has an outer shell 6 through which air flows and a central mushroom 7, which also flows through air. In this case, air nozzles 8 are arranged on the outer shell 6 and / or on the mushroom 7, which are directed towards the bottom of the diffuser 1 and which cause the air flow 4 circulating in the diffuser 1. In essence, the air nozzles 8 are at least turned backwards on the mushroom 7, that is, an original air stream 4 'blown into the diffuser 1 by the hairdryer 2 (see FIG. Fig. 2 ).

Um ein Herausblasen von in den Diffusor 1 eingesaugten und dort getrockneten Haaren 5 zu vermeiden, sind die bodenseitigen Luftauslassöffnungen 3 vorzugsweise mit einem luftdurchlässigen Gitter 9 belegt, die ausgefallene Haare im Diffusor 1 zurückhalten. Die Luftdüsen 8 am Pilz und an der Außenschale 6 sind darüber hinaus so ausgerichtet bzw. positioniert, dass sie eine Lockenbildung der in den Diffusor 1 eingelegten oder eingesaugten Haare 5 zumindest unterstützen. Generell kann der Diffusor 1 aus Kunststoffen, insbesondere als kostengünstiges und individuell zu fertigendes Kunststoffspritzgussteil ausgebildet sein.In order to avoid blowing out of hair 5 sucked into the diffuser 1 and dried there, the bottom-side air outlet openings 3 are preferably covered with an air-permeable grid 9, which hold back the hair which has fallen out in the diffuser 1. The air nozzles 8 on the mushroom and on the outer shell 6 are moreover aligned or positioned in such a way that they at least support curl formation of the hairs 5 inserted or sucked into the diffuser 1. In general, the diffuser 1 can be made of plastics, in particular as a cost-effective and custom-made plastic injection molded part.

Zweckmäßig ist am Haartrockner 2 darüber hinaus ein Sensor 10, insbesondere ein Schalter, vorgesehen, der erkennt, ob ein Diffusor 1 auf den Haartrockner 2 aufgesetzt ist und der in diesem Fall eine Trocknungstemperatur entsprechend steuert, das heißt insbesondere absenkt.Appropriately, the hair dryer 2 beyond a sensor 10, in particular a switch provided, which detects whether a diffuser 1 is placed on the hair dryer 2 and in this case controls a drying temperature accordingly, ie in particular lowers.

Der erfindungsgemäße Diffusor 1 lenkt somit den Luftstrom 4 in diesem derart um, dass die zu trocknenden Haare 5 auf den Boden des Diffusors 1 gedrückt werden und insbesondere auch in den Diffusor 1 eingesaugt werden, wobei der Luftstrom 4 den Diffusor zumindest überwiegend über die bodenseitigen Auslassöffnungen 3 wieder verlässt. Die Luftdüsen 8 an der Außenschale 6 und am zentralen luftdurchströmten Pilz 7 sind darüber hinaus derart ausgerichtet, dass zusätzlich zur zirkulierenden Luftströmung 5 auch eine Wirbelbildung in der Art einer Spirale erzeugt wird. Im Unterschied zu aus dem Stand der Technik bekannten Diffusoren werden die zu trocknenden Haare 5 beim erfindungsgemäßen Diffusor 1 nicht von diesem weggeblasen, sondern vielmehr an- bzw. eingesaugt, wodurch ein deutlich verbesserter Trocknungseffekt erzielt werden kann. Durch Einlegen der zu trocknenden Haare 5 in den Diffusor 1 kann darüber hinaus die Eigenlockenbildung verstärkt bzw. unterstützt werden.The diffuser 1 of the invention thus deflects the air flow 4 in this so that the hair to be dried 5 are pressed onto the bottom of the diffuser 1 and In particular, be sucked into the diffuser 1, wherein the air flow 4 leaves the diffuser at least predominantly on the bottom outlet openings 3 again. The air nozzles 8 on the outer shell 6 and the central air-flowed mushroom 7 are also aligned such that in addition to the circulating air flow 5 and a vortex formation in the manner of a spiral is generated. In contrast to diffusers known from the prior art, the hairs 5 to be dried in the diffuser 1 according to the invention are not blown off the latter, but instead are sucked in or sucked in, whereby a significantly improved drying effect can be achieved. By inserting the hairs to be dried 5 in the diffuser 1, moreover, the self-curling can be enhanced or supported.
