Description

Die vorliegende Erfindung betrifft eine Filtereinrichtung sowie ein Verfahren zur Reinigung einer solchen Filtereinrichtung für ein elektrisch betriebenes luftdurchströmbares Haarpflegegerät, insbesondere für einen Haartrockner, eine Warmluftlockenbürste oder dergleichen mit einem Filterelement, welches eine Innen- und eine Außenseite aufweist und wobei die Innenseite des Filterelementes im Bereich einer Lufteinlaßöffnung des Gerätes angeordnet ist.The present invention relates to a filter device and a method for cleaning Such a filter device for an electrically operated air flow Hair care device, in particular for a hairdryer, a hot air curling brush or the like with a filter element which has an inside and an outside and wherein the inside of the filter element in the region of an air inlet opening of the Device is arranged.

Eine solche Filtereinrichtung ist aus der EP 0 518 035 B1 bekannt. Diese zeigt einen Haaransaugfilter, welcher zwischen einem fest mit dem Gerätegehäuse verbundenen Lufteinlaßgitter und einer abnehmbaren Gitterkappe angeordnet ist. Das Filterelement selbst ist aus einem Gewebevlies hergestellt. Zum Reinigen des Filterelementes muß zunächst die Gitterkappe entfernt und dann das Filterelement herausgenommen und gereinigt, bzw. getauscht werden. Filtereinrichtungen für luftdurchströmbare Geräte, insbesondere für Haartrockner, sind dafür vorgesehen, um ein Eindringen von unerwünschten Verunreinigungen, wie beispielsweise Haaren, Flusen, Staub oder ähnliches, in den Innenraum des Haartrockners zu vermeiden und somit eine Verschmutzung und mögliche Beschädigung des Haartrockners zu verhindern.Such a filter device is known from EP 0 518 035 B1. This shows you Hair suction filter, which is firmly connected to the device housing Air inlet grille and a removable grille cap is arranged. The filter element itself is made from a woven fabric. To clean the filter element must first removed the mesh cap and then removed the filter element and cleaned or exchanged. Filter devices for air flow devices, especially for hair dryers, are intended to prevent unwanted intrusion Impurities such as hair, fluff, dust or the like, to avoid in the interior of the hair dryer and thus contamination and to prevent possible damage to the hair dryer.

Bei den oben genannten Filtereinrichtungen für elektrisch betriebene luftdurchströmbare Geräte, insbesondere für Haartrockner hat sich gezeigt, daß die erforderliche Reinigung der Einrichtung durch den Benutzer nicht regelmäßig durchgeführt wird oder sogar gänzlich unterbleibt. Bei dem eingangs genannten Gerät mit einem abnehmbaren Filterelement gemäß der EP 0 518 035 B1 ist erfahrungsgemäß der Verschmutzungsgrad des vliesartigen Filterelementes nicht immer eindeutig durch den Benutzer erkennbar. Eine stärkere Verschmutzung des Filterelementes hat jedoch nachteiligerweise eine höhere thermische Belastung des Haartrockners zur Folge, welche bis zur Abschaltung oder Beschädigung des Gerätes führen kann. Die Reinigung des Filterelementes ist somit verbesserungsfähig, da zunächst die Gitterkappe demontiert, das Filterelement entnommen und anschließend gereinigt werden muß. Ferner ist durch eine unregelmäßige Struktur des vliesartigen Filterelementes eine Reinigung dadurch erschwert, daß sich vorw:egend Haare, Flusen und Staub in dem Filterelement festsetzen, bzw. verhaken. In the above filter devices for electrically operated air flow Devices, especially for hair dryers, have been shown to have the necessary cleaning the installation is not carried out regularly by the user or even completely omitted. In the device mentioned at the beginning with a removable filter element according to EP 0 518 035 B1, experience has shown that the degree of soiling of the fleece-like filter element not always clearly recognizable by the user. A However, severe contamination of the filter element disadvantageously has a higher level result in thermal stress on the hair dryer, which until switch off or Damage to the device. The cleaning of the filter element is thus room for improvement, since the grille cap was first removed and the filter element removed and then has to be cleaned. Furthermore, by an irregular Structure of the fleece-like filter element makes cleaning difficult because Predominantly, fix or catch hair, lint and dust in the filter element.

Eine Naßreinigung des Filterelementes ist zwar möglich, erfordert jedoch eine vorschriftsmäßige Trocknung vor dem Wiedereinbau durch den Benutzer.Wet cleaning of the filter element is possible, but requires a correct one Dried by the user before reinstallation.

Andere Filtereinrichtungen, welche nicht durch eine Gitterkappe abgedeckt sind, zeigen meist eine Struktur, welche zwar das Eindringen von Flusen und Haaren in das Innere des Haartrockners verhindern, diese sind jedoch nur schwer durch den Benutzer zu reinigen. Da ferner die äußere Erscheinung eines Haartrockners mit und ohne Filter nahezu gleich ist, setzen viele Benutzer nach einer unzufriedenstellenden Reinigung des Filterelementes dieses nicht wieder auf die Lufteinlaßöffnung des Trockners auf und betreiben danach den Haartrockner ohne Filter. Somit gelangen nachteiligerweise zwangsläufig Haare, Flusen oder Staub in den Haartrockner und führen nach einer gewissen Betriebsdauer zur Verschmutzung und Überhitzung bzw. Beschädigung des Gerätes.Other filter devices, which are not covered by a grid cap, show mostly a structure that prevents the penetration of fluff and hair into the Prevent the inside of the hair dryer, but these are difficult for the user to clean. Furthermore, since the external appearance of a hair dryer with and without Filter is almost the same, many users put after unsatisfactory cleaning of the filter element this does not return to the air inlet opening of the dryer and then operate the hair dryer without a filter. Thus, disadvantageously inevitably hair, fluff or dust in the hair dryer and run after a certain operating time for contamination and overheating or damage of the device.

Aus der CH 676540 ist es weiterhin allgemein bekannt, im Lufteinlaßbereich eines Haartrockners einen Filter und/oder ein Filtergitter anzuordnen.From CH 676540 it is also generally known, in the air inlet area Arrange hair dryer a filter and / or a filter grid.

Aus der US 4,924,602 ist ein Haartrockner bekannt, der im Lufteinlaßbereich ein spinnennetzartig ausgebildetes Kunststoffgitter aufweist, das mit ringförmigen, radial abschnittsweise unterbrochenen Öffnungen versehen ist.From US 4,924,602 a hair dryer is known which is in the air inlet area Has a spider web-like plastic grille that has an annular, radial intermittently interrupted openings is provided.

Aus der WO 95/31915 ist es daneben allgemein bekannt, eine gelochte Metallfolie im Lufteinlaßbereich des Haartrockners anzuordnen.From WO 95/31915 it is also generally known to use a perforated metal foil in the To arrange the air inlet area of the hair dryer.

Weiterhin ist aus der US 5,490,336 ein Haartrockner bekannt, der im Lufteinlaßbereich einen waschbaren Schaumstoff aufweist, um Haare und Flusen vor dem Eindringen in den Haartrockner abzuhalten.Furthermore, a hair dryer is known from US 5,490,336, which is in the air inlet area has a washable foam to keep hair and lint from penetrating to hold in the hair dryer.

Aufgabe der vorliegenden Erfindung ist es daher, eine Filtereinrichtung für ein elektrisch betriebenes luftdurchströmbares Haarpflegegerät, insbesondere für einen Haartrockner anzugeben, welche zunächst eine Verschmutzungsanzeige enthält und dem Benutzer signalisiert, die Filtereinrichtung zu einem frühest möglichen Zeitpunkt zu reinigen. Ferner soll die Filtereinrichtung so gestaltet sein, daß die Reinigung selbst durch den Benutzer leicht durchführbar ist. The object of the present invention is therefore to provide a filter device for an electrical operated air flow hair care device, in particular for one Specify hair dryer, which initially contains a clogging indicator and signals to the user that the filter device is at the earliest possible time to clean. Furthermore, the filter device should be designed so that the cleaning is easy to carry out even by the user.

Erfindungsgemäß wird die Aufgabe bei einer oben beschriebenen Filtereinrichtung im wesentlichen durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst. Dieser sieht vor, daß das Filterelement als eine Art Gewebe, Lochfolie oder dergleichen mit einer relativ geringen Dicke ausgebildet ist und daß die von dem Filterelement zurückgehaltenen Verunreinigungen, wie Haare, Flusen oder Staub im wesentlichen an der Außenseite des Filterelementes abgelagert werden und daß die Außenseite des Filterelementes für den Benutzer im wesentlichen frei zugänglich an dem Haarpflegegerät angeordnet ist. Das Filterelement weist ein einlagiges Gewebe mit einem Verhältnis der Maschenweite zum Fadendurchmesser von 80 µm/55 µm bis 1200 µm/400 µm auf. Erfindungsgemäß beträgt die von der Luft durchströmbare offenen Fläche des Filterelementes ca. 30 bis 60% der gesamten angeströmten Fläche des Filterelementes und die Gewebefäden, bzw. die Stege der Lochfolie weisen eine Faden-Dicke bzw. Stegbreite kleiner oder gleich 400 µm auf. Somit ist der erforderliche Luftdurchsatz durch das Gerät, insbesondere durch einen Haartrockner so groß gewählt, daß der Haartrockner nicht überhitzt. Andererseits ist durch die Fadendicke bzw. Stegbreite eine Öffnungsgröße des Filterelementes angegeben, welche Flusen und Haare effektiv zurückhält; kleinste Staubpartikel dagegen können das Filterelement passieren und den Haartrockner durchströmen.According to the invention, the object is achieved in a filter device described above essentially solved by the characterizing features of claim 1. This provides that the filter element as a kind of tissue, perforated film or the like is formed with a relatively small thickness and that of the filter element retained contaminants such as hair, lint or dust essentially be deposited on the outside of the filter element and that the outside of the filter element for the user essentially freely accessible on the Hair care device is arranged. The filter element has a single-layer fabric a ratio of the mesh size to the thread diameter of 80 µm / 55 µm to 1200 µm / 400 µm. According to the invention, the open air can flow through Area of the filter element approx. 30 to 60% of the total flow area of the filter element and the fabric threads, or the webs of the perforated film have a Thread thickness or web width less than or equal to 400 µm. So the required Air flow through the device, especially through a hair dryer as great chosen so that the hair dryer does not overheat. On the other hand, by the thread thickness or web width an opening size of the filter element specified, which fluff and effectively holds back hair; The smallest dust particles, however, can be the filter element pass and flow through the hair dryer.

Bei einer derartigen Filtereinrichtung hat sich vorteilhafterweise gezeigt, daß zum einen durch die erfindungsgemäße Beschaffenheit der Oberflächenstruktur des Filterelements sowie zum anderen dadurch, daß die Außenseite des Filterelementes im wesentlichen frei zugänglich ist, sich nach dem Abschalten des Gerätes, insbesondere nach dem Abschalten des Lüftermotors ein Großteil der Verunreinigungen bereits selbständig von dem Filterelement löst. Eine Kammerbildung auf der Außenseite des Filterelementes, welche von Geräten nach dem Stand der Technik bekannt ist und welche zu Ansammlungen von Haaren und Flusen in den durch das Lufteinlaßgitter gebildeten Kammern führt, wird vorteilhafterweise vermieden. Die an dem Filterelement verbleibenden Verunreinigungen, wie Haare und Flusen können von dem Benutzer unmittelbar nach dem Entstehen erkannt und durch Wischen über die Außenseite des Filterelementes, beispielsweise mit der bloßen Hand des Benutzers, von dem Filterelement entfernt werden. Eine zusätzliche Verschmutzungsanzeige ist somit vorteilhafterweise nicht erforderlich. Der Benutzer erkennt bei jedem Gebrauch des Haartrockners umgehend und eindeutig den jeweiligen Verschmutzungsgrad des Filters und wird somit auf eine regelmäßige Reinigung des Filterelementes hingewiesen.With such a filter device, it has advantageously been shown that, on the one hand due to the nature of the surface structure of the filter element according to the invention and on the other hand in that the outside of the filter element in substantially is freely accessible after switching off the device, especially after Switching off the fan motor already a large part of the contamination independently detaches from the filter element. A chamber formation on the outside of the filter element, which is known from devices according to the prior art and which to Accumulations of hair and lint in the air intake grille Chamber leads, is advantageously avoided. Those remaining on the filter element Contaminants, such as hair and lint, can be removed directly from the user recognized after formation and by wiping over the outside of the filter element, for example, with the user's bare hand, from the filter element be removed. An additional contamination indicator is therefore advantageous not mandatory. The user recognizes each time the hair dryer is used immediately and clearly the respective degree of contamination of the filter and attention is thus drawn to regular cleaning of the filter element.

In einer besonders vorteilhaften Weiterbildung der Erfindung ist das Filterelement als Siebgewebe ausgebildet, welches aus Fäden mit einer insbesondere runden Querschnittsfläche besteht. Dadurch wird zum einen ein strömungsgünstiger Querschnitt der Gewebefäden angegeben und zum anderen eine leichte Entfernung der Verunreinigungen von dem Filterelement bzw. dem Siebgewebe ermöglicht, ohne daß sich die Verunreinigungen in dem Filterelement verhaken können.In a particularly advantageous development of the invention, the filter element is as Screen fabric formed, which consists of threads with a particularly round cross-sectional area consists. On the one hand, this creates a streamlined cross-section of the fabric threads and, on the other hand, easy removal of the impurities made possible by the filter element or the screen fabric without the contaminants can get caught in the filter element.

In einer Weiterbildung des Filterelementes wird vorgeschlagen, das Siebgewebe aus einem thermoplastischen Kunststoff, wie beispielsweise Polypropylen oder Polyacryl herzustellen. Besonders vorteilhaft hat sich die Verwendung von Polyester (PES) gezeigt, welches ein sehr pflegeleichtes, reißfestes und nicht hygroskopisches Material darstellen.In a further development of the filter element, it is proposed that the screen fabric be made of a thermoplastic, such as polypropylene or polyacrylic manufacture. The use of polyester (PES) has proven particularly advantageous which is a very easy-care, tear-resistant and non-hygroscopic material represent.

In einer anderen Weiterbildung weist das Siebgewebe ein Verhältnis der Maschenweite zum Fadendurchmesser von ca. 400 µm/200 µm auf. Es kann somit vorteilhafterweise ein einlagiges Siebgewebe verwendet werden, welches beispielsweise auch einem Strumpfgewebe ähnlich ist. In another development, the screen fabric has a ratio of the mesh size to the thread diameter of approx. 400 µm / 200 µm. It can therefore advantageously a single-layer screen fabric can be used, which for example is similar to a hosiery.

In einer alternativen Ausführung des Siebgewebes, besteht dieses aus einem duroplastischen Kunststoff, aus Naturgarnen, Metall oder aus einem Glasgewebe. Dadurch kann beispielsweise ein besonders haltbares Siebgewebe oder eine weiche bzw. harte Oberfläche für ein Siebgewebe erzeugt werden.In an alternative embodiment of the screen fabric, this consists of a thermosetting Plastic, from natural yarns, metal or from a glass fabric. This can for example, a particularly durable screen mesh or a soft or hard surface for a screen mesh.

In einer besondern Weiterbildung des Filterelementes weist dieses wenigstens auf der Außenseite eine dunkle Farbe, insbesondere schwarz oder anthrazit auf. Da die von dem Filterelement zurückgehaltenen Verunreinigungen meist eine helle Farbe aufweisen, sind diese somit besonders, einfach und schnell durch den Benutzer auf der dunklen Außenseite des Filterelementes zu erkennen und signalisieren dem Benutzer auf vorteilhafte Weise das Filterelement zu reinigen.In a special development of the filter element, this has at least on the Outside a dark color, especially black or anthracite. Because of that Impurities retained in the filter element usually have a light color this makes it special, simple and quick for the user on the dark outside to recognize the filter element and signal the user to advantageous Way to clean the filter element.

In einer Weiterbildung der Erfindung ist das Filterelement durch ein Haltemittel an dem Gerätegehäuse befestigbar, wobei das Haltemittel an dem äußeren, die Lufteinlaßöffnung umgebenden Rand des Filterelementes angreift. Da das Filterelement meist aus einem alleine nicht formstabilen Material besteht, insbesondere einem Siebgewebe, einer Lochfolie oder dergleichen, welches ohne Haltemittel an dem Gerätegehäuse nur ungenügend befestigbar ist, wird dieses vorteilhafterweise durch ein separates Haltemittel an dem Gerätegehäuse befestigt. Das Haltemittel, welches insbesondere an dem äußeren Rand des Filterelementes angreift verkleinert somit nicht die Querschnittsfläche der Lufteinlaßöffnung bzw. behindert nicht die Luftströmung durch das Gerät. Das Haltemittel selbst ist als Klemmring und/oder als Trägerelement ausgebildet, welches insbesondere als ein Trägergitter ausgeformt ist. Somit kann vorteilhafterweise das Filterelement durch einen Klemmring oder ein Trägerelement, insbesondere ein Trägergitter alleine an dem Gerätegehäuse befestigt werden. Es kann jedoch auch eine Halterung des Filterelementes durch einen Klemmring und ein Trägergitter erfolgen,wobei diese Teile gemeinsam eine Filtereinrichtung bilden. Dies ist besonders vorteilhaft, da sich das Trägergitter auf der Innenseite des Filterelementes befindet und das Filterelement somit durch das Trägergitter gestützt wird.In a development of the invention, the filter element is attached to the by a holding means Device housing attachable, with the holding means on the outer, the air inlet opening surrounding edge of the filter element attacks. Since the filter element mostly made a material that is not dimensionally stable on its own, in particular a screen fabric, one Perforated film or the like, which is insufficient on the device housing without holding means can be fastened, this is advantageously carried out by a separate holding means attached to the device housing.
