Definitions
- the invention relates to a hair care appliance according to the preamble of claim 1, in particular a hair dryer.
- the ionization device comprises a high-voltage circuit formed by a pulse generator circuit which feeds an ionization electrode located in an end region of a hot air line.
- the DE 29 19 598 describes two embodiments of a hair dryer with an ionization device.
- the first embodiment relates to a hand-held hair dryer.
- This includes an air duct with an electrical heating resistor.
- a generator is housed with a piezoelectric transducer, which is connected to a current-conducting cable.
- the cable runs out into a metal electrode.
- the metal electrode has a needle-shaped tip. The tip is arranged obliquely in the air duct, wherein the cable is guided outside the air duct. What the tip is made of and how the metal electrode is connected to the cable is not described. At most, it is described that the electrode is stamped out of sheet metal.
- the metal electrode is explained in connection with the second embodiment, which refers to a drying hood.
- the second embodiment refers to a drying hood.
- the four electrodes are arranged radially to the air flow and are punched out of sheet metal.
- the electrodes are connected by a ring, which was obtained together with them in one piece.
- the ring is connected to a cable outside the hood. At the other end of the cable is a foot pedal, in the generator is integrated.
- Such a solution with a plurality of radial electrodes requires a relatively high voltage source and is unsuitable for handheld devices.
- the defined thin-plate electrode tips emit a well-defined ion field at the tip.
- the ionization device consists of a high voltage source with a piezoelectric generator and an electrode within a vacuum layer.
- the high voltage source is located outside a vacuum chamber. There is a high resistance between the high voltage source and the cable.
- this device is provided for the discharge of a film located in the vacuum layer.
- a hair dryer having an ionization device with an electrode.
- a high voltage source is a relatively strong high-voltage cascade. It includes two additional protective resistors connected in series.
- such a high-voltage power source is relatively expensive and disadvantageous for safety reasons. How the electrode is formed is not explained in detail.
- the high voltage generators comprise a cascade connection.
- two spaced approximately cylindrical carbon electrodes are used to achieve a lonisation of the air flow.
- Each electrode is provided with a connecting line, which are each connected via a protective resistor with a generator. Again, relatively strong generators are provided.
- a hairdryer with a lower power high voltage source known.
- the source is formed by a piezoelectric generator.
- a needle-shaped electrode directed in the direction of the air flow is integrated in a protective grid and connected to a connecting cable which leads to the high-voltage source.
- the tip on the electrode enables a high field concentration, a high ion quantity and thus a good efficiency of the ionization device.
- the disadvantage however, that a piezoelectric generator is used, which does not allow continuous ionization.
- the US 6,191,930 describes a hair dryer with an ionization device consisting of a high voltage generator, a separate electrode with a tip and a connecting line.
- the output voltage should be over 6 kV, preferably 7 kV.
- the open circuit voltage is obviously not indicated.
- the electrode and the conduit are arranged approximately centrally in an air duct.
- the tip points to an air outlet. At the transition between the electrode and the connecting line creates an edge.
- the electrode must be held with a metal sheet.
- this solution requires a strong voltage source and that this arrangement is therefore not optimal.
- An accessory for a hairdryer is known.
- the device is designed to neutralize the electrostatic charge of the hair and includes an electrode.
- the invention has for its object to improve a hair care device with an easily integrated in the device lonisationsvoriques according to the preamble of claim 1 such that the efficiency of the ionization device is further increased.
- a high voltage source with small dimensions and with a continuous ionizing voltage can be used.
- the ionization electrode is integrally formed from the electrical conductor.
- the invention is based on the surprising finding that a connection point between the high-voltage cable and the electrode ensures a significant reduction in the amount of ions.
- soldering, riveting or other joints between the cable and the electrode namely incalculable losses that require a higher dimensioning of the high voltage source.
- the electrode can enter the high-voltage source without interruption, ie without intermediate parts or connecting means, the ion emission is optimized in a simple manner. Edges, steps or the like which occur during the transition of a separate metal electrode to the connecting cable are prevented by the measure according to the invention. At such edges can already occur field concentrations that are not available depending on the electrode arrangement but mean a significant loss field.
- Additional, external series protective resistors for personal protection can be completely dispensed with by the use of a relatively low-power high-voltage source. Because such a source has a relatively high internal resistance, it is sufficient that integrated resistors in the generator meet protection standards. Such a high voltage source is also cheaper.
- the electrode is so effective that even a high voltage source allowing a continuous ionization effect can be used, with small dimensions and light weight of the high voltage source.
- a preferred high voltage source is a transformer, e.g. powered on the network side.
- Such an electrode training is also very easy to accommodate in a hairdryer.
- the device according to the invention can be easily integrated into existing devices.
- the invention Due to the one-piece design of the electrode no additional holding parts are required.
- the invention therefore requires few parts and results in a low assembly cost. This also allows the electrode to be positioned relatively freely in or on the hairdryer housing.
- a capacitive load by surrounding holding parts or other materials does not take place.
- the fact that no additional holding parts for the electrode are required eliminates the parallel capacitances or impedances that arise through the holding parts and / or insulators for the electrode.
- edges or e.g. Punching burrs of the holding parts that arise during their production are not in the direction of airflow and degrade efficiency, also because they produce electrical loss fields.
- a parallel capacitance Cp is relatively large. This is proportional to an effective surface. While in the solution according to the invention, the effective surface is very small and is for example 16 mm 2 , such an arrangement according to the prior art may have a surface of eg 148 mm 2 .
- the latter is composed, for example, of a surface of a wire of, for example, 16 mm 2 , a surface of a sheet of 100 mm 2 and a surface of a tip of, for example, 32 mm 2 , ie an approximately 10-fold surface and thus an approximately 10-fold capacity ,
- a parallel resistance Rp is inversely proportional to the surface. Accordingly, this is only about 1/10 compared to the prior art.
- the solution according to the invention thus enables a defined emission of ions with a low effective surface or a high parallel impedance.
- a low parallel impedance is very disadvantageous because it forms a voltage divider with the internal resistance of the high voltage source. This has the consequence that a high voltage drop occurs at the internal resistance of the high voltage source, which is not usable for ionization.
- the useful voltage at the electrode is almost the open circuit voltage of the high voltage source by the electrode formation according to the invention. Open circuit voltages below as low as 6 kV are high efficiency and high internal resistance of e.g. 10 megohms possible. The low voltage allows the use of a low-cost transformer.
- the pointed region of the ionization electrode is formed by processing, preferably cutting off the electrical conductor. At the e.g. cut leaders arise ridges that have sharp and sharp points. At these points, a high field concentration occurs, so that a high ion emission takes place.
- a pointed area is easily created when the conductor is cut off at an angle.
- the tip thus formed is easy to produce and favors the emission of ions.
- a further improvement in the emission behavior of the electrode is given when the cable is a stranded wire stranded wire and / or a multi-core cable forming multiple pointed areas.
- the amount of use of the ions is increased in a cost effective manner.
- the individual ends of the Litzeadern can lie next to and / or behind each other.
- the ionization electrode runs in the direction of an air channel.
- a good ionization effect arises when the ionization electrode is arranged in the vicinity of an air outlet opening.
- the ions can be easily blown out and are available in the blow-off stream for neutralization.
- the ionization device works particularly effectively when the electrode is arranged approximately centrally in the air duct. There prevails a favorable volume flow.
- a light attachment of the ionization electrode is achieved by placing it in a heated region of the air channel, in particular when the cable is passed through a heat carrier plate and fastened there. This is an ion emitting point in a simple manner in the air flow.
- the attachment of the cable can be made at an isolated location of the cable with a holding element, preferably a screwed-on holding clamp on the support plate.
- the invention is applicable not only to a hair dryer but also to other hair care appliances, e.g. in curlers or curling irons, with no heated air flow must occur. Heating may also be by convection, e.g. in gas-powered curling irons or so-called "straightener".
- the invention can be applied to hair stylers, hair brushes with a power supply to the transformer with battery voltage, drying hoods or other hair care appliances. A use in air conditioners, humidifiers, air conditioning and the like is conceivable.
- Fig. 1 shows a hairdryer 1, which is designed as a handheld device.
- This preferably has a plastic housing 2 and a handle 3.
- the housing 2 is approximately tubular and provided with an air inlet side 4 and an eg opposite air outlet side or air outlet opening 5.
- known components such as a fan, not shown, one or more heating elements and the ionization integrated.
- a protective grille 7 or other protective cover can be fastened.
- the protective grid is preferably not made of plastic but metallic, because a plastic protective grid is more susceptible to electrical charges and electrical interference.

- a high-voltage generator which comprises a cascade circuit, a piezoelectric element or another generation element. At least the voltage is 1000V, which is already referred to as high voltage. Preferably, negative ions are used to unload the hair.
- the internal resistance of the high voltage source is relatively high and is in particular about 5 to 20 megohms, in particular about 10 megohms, so that a short circuit current of at most about 1.4 mA (eg 7kV / 5 megohms), preferably about 0.3 to 0.4 mA (eg 3 kV / 10 megohms) would be possible. This current is safe for people, so that even with direct contact with the electrode 12 no danger.

- the cable 13 is fixed exactly centric to slightly eccentric to the axis of the air duct. At most, the electrode 12 is spaced about 10 to 15 mm from the axis. In essence, it is still centric.
- the cable 13 is arranged axially to the air flow and leaves this orientation only in the vicinity of the handle 3, as Fig. 1 and 2 demonstrate.
- the cable 13 is attached to a guiding and / or fastening element, preferably made of electrical insulating material.
- the cable 13 is on a Schuelementmay, in particular on one of a plurality of carrier plates 6, in particular a Mikanitnches or other Mikanitan extract, preferably with two or four or three or six plates 6, such as Fig. 3 shows, attached.

Abstract
Description
Die Erfindung betrifft ein Haarpflegegerät nach dem Oberbegriff des Anspruches 1, insbesondere einen Haartrockner.The invention relates to a hair care appliance according to the preamble of
Beim Bürsten, Kämmen oder Abtrocknen von Haaren, werden diese statisch aufgeladen bzw. elektrisiert, was zu unerwünschten Effekten führt. Durch diese Elektrisierung wird das Haar schwerer frisierbar. Außerdem zieht das Haar Staubteilchen an und verschmutzt schnell.When brushing, combing or drying hair, they are statically charged or electrified, which leads to undesirable effects. This electrification makes the hair harder to style. In addition, the hair attracts dust particles and soils quickly.

Die
Die erste Ausführungsform bezieht sich auf einen Handhaartrockner. Dieser umfasst einen Luftkanal mit einem elektrischen Heizwiderstand. Innerhalb eines Griffes ist ein Generator mit einem piezoelektrischen Wandler untergebracht, welcher mit einem stromleitenden Kabel verbunden ist. Am anderen Ende läuft das Kabel in eine Metallelektrode aus. Die Metallelektrode besitzt eine nadelförmige Spitze. Die Spitze ist schräg im Luftkanal angeordnet, wobei das Kabel außerhalb des Luftkanals geführt ist. Woraus die Spitze hergestellt ist und wie die Metallelektrode mit dem Kabel verbunden ist wird nicht beschrieben. Allenfalls ist beschrieben, dass die Elektrode aus Feinblech ausgestanzt ist.The first embodiment relates to a hand-held hair dryer. This includes an air duct with an electrical heating resistor. Within a handle, a generator is housed with a piezoelectric transducer, which is connected to a current-conducting cable. At the other end, the cable runs out into a metal electrode. The metal electrode has a needle-shaped tip. The tip is arranged obliquely in the air duct, wherein the cable is guided outside the air duct. What the tip is made of and how the metal electrode is connected to the cable is not described. At most, it is described that the electrode is stamped out of sheet metal.
Etwas genauer wird die Metallelektrode im Zusammenhang mit dem zweiten Ausführungsbeispiel erläutert, welches sich auf eine Trockenhaube bezieht. Im Inneren der Haube befinden sich vier Elektroden unterhalb eines elektrischen Heizwiderstandes und eines Ventilator. Die vier Elektroden sind radial zum Luftstrom angeordnet und werden aus Feinblech ausgestanzt. Die Elektroden werden durch einen Ring miteinander verbunden, welcher mit ihnen zusammen aus einem Stück erhalten wurde. Der Ring ist mit einem außerhalb der Haube geführten Kabel verbunden. Am anderem Ende des Kabels befindet sich ein Fußpedal, in dem der Generator integriert ist. Eine derartige Lösung mit mehreren radialen Elektroden benötigt eine relativ starke Hochspannungsquelle und ist für Handgeräte untauglich. Die definierten Feinblech-Elektrodenspitzen geben an der Spitze ein gut definiertes lonenfeld ab.More specifically, the metal electrode is explained in connection with the second embodiment, which refers to a drying hood. Inside the hood are four electrodes below an electrical heating resistor and a fan. The four electrodes are arranged radially to the air flow and are punched out of sheet metal. The electrodes are connected by a ring, which was obtained together with them in one piece. The ring is connected to a cable outside the hood. At the other end of the cable is a foot pedal, in the generator is integrated.

Der Erfindung liegt die Aufgabe zugrunde, ein Haarpflegegerät mit einer leicht im Gerät integrierbaren lonisationsvorrichtung nach dem Oberbegriff des Anspruches 1 derart zu verbessern, dass der Wirkungsgrad der lonisationsvorrichtung weiter erhöht wird. Insbesondere soll es möglich sein, dass eine Hochspannungsquelle mit geringen Abmessungen und mit einer kontinuierlichen lonisierungsspannung eingesetzt werden kann.The invention has for its object to improve a hair care device with an easily integrated in the device lonisationsvorrichtung according to the preamble of
Diese Aufgabe wird dadurch gelöst, dass die lonisationselektrode einstückig aus dem elektrischen Leiter gebildet ist.This object is achieved in that the ionization electrode is integrally formed from the electrical conductor.
Die Erfindung beruht auf der überraschenden Erkenntnis, dass eine Verbindungsstelle zwischen dem Hochspannungskabel und der Elektrode für eine deutliche Reduzierung der lonenmenge sorgt. Durch Lötstellen, Nietverbindungen oder andere Verbindungsstellen zwischen dem Kabel und der Elektrode entstehen nämlich unkalkulierbare Verluste, die eine höhere Dimensionierung der Hochspannungsquelle erfordern. Dadurch dass die Elektrode unterbrechungslos - also ohne Zwischenteile oder Verbindungsmittel - zur Hochspannungsquelle gelangen kann, wird der lonenaustoß in einfacher Weise optimiert. Kanten, Stufen oder dergleichen die beim Übergang einer separaten Metallelektrode zum Verbindungskabel entstehen werden durch die erfindungsgemäße Maßnahme verhindert. An solche Kanten können bereits Feldkonzentrationen auftreten, die je nach Elektrodenanordnung nicht nutzbar sind aber ein erhebliches Verlustfeld bedeuten.The invention is based on the surprising finding that a connection point between the high-voltage cable and the electrode ensures a significant reduction in the amount of ions. By soldering, riveting or other joints between the cable and the electrode namely incalculable losses that require a higher dimensioning of the high voltage source. As a result of the fact that the electrode can enter the high-voltage source without interruption, ie without intermediate parts or connecting means, the ion emission is optimized in a simple manner. Edges, steps or the like which occur during the transition of a separate metal electrode to the connecting cable are prevented by the measure according to the invention. At such edges can already occur field concentrations that are not available depending on the electrode arrangement but mean a significant loss field.
Auf zusätzliche, externe in Reihe geschaltete Schutzwiderstände zum Personenschutz kann durch den Einsatz einer relativ leistungsschwachen Hochspannungsquelle gänzlich verzichtet werden. Weil eine solche Quelle einen relativ hohen Innenwiderstand besitzt, ist es ausreichend, dass im Generator integrierte Widerstände Schutznormen erfüllen. Eine solche Hochspannungsquelle ist zudem kostengünstiger.Additional, external series protective resistors for personal protection can be completely dispensed with by the use of a relatively low-power high-voltage source. Because such a source has a relatively high internal resistance, it is sufficient that integrated resistors in the generator meet protection standards. Such a high voltage source is also cheaper.
Die Elektrode ist so effektiv, dass sogar eine Hochspannungsquelle, die einen kontinuierlichen lonisierungseffekt erlaubt, eingesetzt werden kann, wobei geringe Abmessungen und ein geringes Gewicht der Hochspannungsquelle gegeben sind. Eine bevorzugte Hochspannungsquelle ist ein Transformator, der z.B. netzseitig gespeist wird.The electrode is so effective that even a high voltage source allowing a continuous ionization effect can be used, with small dimensions and light weight of the high voltage source. A preferred high voltage source is a transformer, e.g. powered on the network side.
Eine solche Elektrodenausbildung ist zudem sehr einfach in einem Haartrockner unterzubringen. Außerdem lässt sich die erfindungsgemäße Vorrichtung leicht in vorhandene Geräte integrieren.Such an electrode training is also very easy to accommodate in a hairdryer. In addition, the device according to the invention can be easily integrated into existing devices.
Durch die einstückige Ausbildung der Elektrode sind keine zusätzlichen Halteteile erforderlich. Durch die Erfindung werden daher wenige Teile benötigt und es ergibt sich ein geringer Montageaufwand. Dadurch kann außerdem die Elektrode relativ frei im oder am Haartrocknergehäuse positioniert werden.Due to the one-piece design of the electrode no additional holding parts are required. The invention therefore requires few parts and results in a low assembly cost. This also allows the electrode to be positioned relatively freely in or on the hairdryer housing.
Eine kapazitive Belastung durch umgebende Halteteile oder andere Materialien findet nicht statt. Dadurch dass keine zusätzliche Halteteile für die Elektrode benötigt werden, entfallen parallele Kapazitäten bzw. Impedanzen, die durch die Halteteile und/oder Isolatoren für die Elektrode entstehen. Außerdem entfallen Kanten oder z.B. Stanzgrate der Halteteile, die bei ihrer Herstellung entstehen. Diese Stanzgrate nach dem Stand der Technik liegen nicht in Luftflußrichtung und verschlechtern den Wirkungsgrad, auch weil sie elektrische Verlustfelder erzeugen.A capacitive load by surrounding holding parts or other materials does not take place. The fact that no additional holding parts for the electrode are required eliminates the parallel capacitances or impedances that arise through the holding parts and / or insulators for the electrode. In addition, edges or e.g. Punching burrs of the holding parts that arise during their production. These prior art burrs are not in the direction of airflow and degrade efficiency, also because they produce electrical loss fields.
Bei einer aus einem Blech hergestellten oder einer durch ein Halteblech gehalterten separaten Elektrode ist eine parallele Kapazität Cp relativ groß. Diese ist einer wirksamen Oberfläche proportional. Während bei der erfindungsgemäßen Lösung die wirksame Oberfläche sehr gering ist und beispielsweise 16 mm2 beträgt, kann eine derartige Anordnung nach dem Stand der Technik eine Oberfläche von z.B. 148 mm2 aufweisen. Letztere setzt sich z.B. zusammen aus einer Oberfläche eines Drahtes von z.B. 16 mm2, einer Oberfläche eines Bleches von 100 mm2 und einer Oberfläche einer Spitze von z.B. 32 mm2, also einer etwa 10-fachen Oberfläche und somit einer etwa 10-fachen Kapazität. Ein paralleler Widerstand Rp ist umgekehrt proportional zur Oberfläche. Entsprechend ist dieser etwa nur 1/10 im Vergleich zum Stand der Technik.In the case of a separate electrode produced from a metal sheet or a separate electrode held by a retaining sheet, a parallel capacitance Cp is relatively large. This is proportional to an effective surface. While in the solution according to the invention, the effective surface is very small and is for example 16 mm 2 , such an arrangement according to the prior art may have a surface of eg 148 mm 2 . The latter is composed, for example, of a surface of a wire of, for example, 16 mm 2 , a surface of a sheet of 100 mm 2 and a surface of a tip of, for example, 32 mm 2 , ie an approximately 10-fold surface and thus an approximately 10-fold capacity , A parallel resistance Rp is inversely proportional to the surface. Accordingly, this is only about 1/10 compared to the prior art.
Die erfindungsgemäße Lösung ermöglicht also eine definierte lonenaussendung mit einer geringen wirksamen Oberfläche bzw. einer hohen parallelen Impedanz.The solution according to the invention thus enables a defined emission of ions with a low effective surface or a high parallel impedance.
Eine geringe parallele Impedanz ist sehr nachteilig, da sie mit dem Innenwiderstand der Hochspannungsquelle einen Spannungsteiler bildet. Dies hat zur Folge, dass ein hoher Spannungsabfall am Innenwiderstand der Hochspannungsquelle entsteht, der für eine lonisierung nicht nutzbar ist. Die nutzbare Spannung an der Elektrode ist durch die erfindungsgemäße Elektrodenausbildung nahezu die Leerlaufspannung der Hochspannungsquelle. Leerlaufspannungen unterhalb von nur 6 kV sind bei einem hohen Wirkungsgrad und einem hohen Innenwiderstand von z.B. 10 Megaohm möglich. Die geringe Spannung ermöglicht den Einsatz eines kostengünstigen Transformators.A low parallel impedance is very disadvantageous because it forms a voltage divider with the internal resistance of the high voltage source. This has the consequence that a high voltage drop occurs at the internal resistance of the high voltage source, which is not usable for ionization. The useful voltage at the electrode is almost the open circuit voltage of the high voltage source by the electrode formation according to the invention. Open circuit voltages below as low as 6 kV are high efficiency and high internal resistance of e.g. 10 megohms possible. The low voltage allows the use of a low-cost transformer.
Zudem entfällt eine Prüfung einer Kontaktstelle zwischen dem Kabel und der Elektrode.In addition, a test of a contact point between the cable and the electrode is omitted.
In einer vorteilhaften Weiterbildung des erfindungsgemäßen Gerätes ist vorgesehen, dass der spitze Bereich der Ionisationselektrode durch Bearbeiten, vorzugsweise Abschneiden des elektrischen Leiters gebildet ist. An der z.B. abgeschnittenen Leiterstelle entstehen Grate, die scharfkantige und spitze Stellen besitzen. An diesen Stellen tritt eine hohe Feldkonzentration auf, so dass eine hohe lonenemission stattfindet.In an advantageous development of the device according to the invention, it is provided that the pointed region of the ionization electrode is formed by processing, preferably cutting off the electrical conductor. At the e.g. cut leaders arise ridges that have sharp and sharp points. At these points, a high field concentration occurs, so that a high ion emission takes place.
Ein spitzer Bereich entsteht in einfacher Weise, wenn der Leiter schräg abgeschnitten wird. Die so gebildete Spitze lässt sich einfach herstellen und begünstigt die Aussendung von lonen.A pointed area is easily created when the conductor is cut off at an angle. The tip thus formed is easy to produce and favors the emission of ions.
Eine weitere Verbesserung des Emissionsverhaltens der Elektrode ist gegeben, wenn das Kabel ein Litzekabel mit Litzeadern und/oder ein mehradriges Kabel ist, die mehrere spitze Bereiche bilden. Hierdurch wird die Nutzmenge der lonen auf kostengünstige Weise erhöht. Die einzelnen Enden der Litzeadern können neben- und/oder hintereinander liegen.A further improvement in the emission behavior of the electrode is given when the cable is a stranded wire stranded wire and / or a multi-core cable forming multiple pointed areas. As a result, the amount of use of the ions is increased in a cost effective manner. The individual ends of the Litzeadern can lie next to and / or behind each other.
Gemäß einer weiteren vorteilhaften Weiterbildung der Erfindung ist vorgesehen, dass die Ionisationselektrode in Richtung eines Luftkanals verläuft. Durch diese Ausrichtung sind kaum parallele Kapazitäten und Widerstände vorhanden, die zu parallelen Strömen führen, die eine erzielbare Spannung reduzieren und den verfügbaren Stromfluß für die lonisierung verringern. Diese Verringerung des Stromflusses sorgt für eine Verschlechterung der Wirkung der lonisationsvorrichtung.According to a further advantageous development of the invention, it is provided that the ionization electrode runs in the direction of an air channel. As a result of this alignment, there are hardly any parallel capacitances and resistances leading to parallel currents which reduce an achievable voltage and reduce the available current flow for the ionization. This reduction of the current flow causes a deterioration of the effect of the ionization device.
Ein guter lonisationseffekt entsteht, wenn die lonisationselektrode in der Nähe einer Luftaustrittsöffnung angeordnet ist. Die lonen können so leicht ausgeblasen werden und stehen im Ausblasstrom für eine Neutralisierung zur Verfügung.A good ionization effect arises when the ionization electrode is arranged in the vicinity of an air outlet opening. The ions can be easily blown out and are available in the blow-off stream for neutralization.
Besonders effektiv arbeitet die lonisationsvorrichtung, wenn die Elektrode etwa zentrisch im Luftkanal angeordnet ist. Dort herrscht ein günstiger Volumenstrom.The ionization device works particularly effectively when the electrode is arranged approximately centrally in the air duct. There prevails a favorable volume flow.
Eine leichte Befestigung der lonisationselektrode wird erreicht, indem diese in einem geheizten Bereich des Luftkanals angeordnet ist, insbesondere wenn das Kabel durch eine Heizträgerplatte geführt und dort befestigt ist. Damit liegt ein lonenemittierpunkt in einfacher Weise im Luftstrom. Die Befestigung des Kabel kann an einer isolierten Stelle des Kabels mit einem Halteelement, vorzugsweise einer aufgeschraubten Halteschelle an der Trägerplatte erfolgen.A light attachment of the ionization electrode is achieved by placing it in a heated region of the air channel, in particular when the cable is passed through a heat carrier plate and fastened there. This is an ion emitting point in a simple manner in the air flow. The attachment of the cable can be made at an isolated location of the cable with a holding element, preferably a screwed-on holding clamp on the support plate.
Die Erfindung ist nicht nur bei einem Haartrockner einsetzbar, sondern auch bei anderen Haarpflegegeräten, z.B. bei Lockenwicklern bzw. Lockenstäben, wobei kein beheizter Luftstrom erfolgen muß. Eine Beheizung kann auch durch Konvektion erfolgen, z.B. in gasbetriebene Lockenstäbe oder sog. "straightener". Eingesetzt kann die Erfindung bei Haarstylern, Haarbürsten mit einer Speisung des Transformators mit Batteriespannung, Trockenhauben oder anderen Haarpflegegeräten werden. Auch ein Einsatz in Klimageräten, Luftbefeuchtern, Klimaanlagen und dergleichen ist denkbar.The invention is applicable not only to a hair dryer but also to other hair care appliances, e.g. in curlers or curling irons, with no heated air flow must occur. Heating may also be by convection, e.g. in gas-powered curling irons or so-called "straightener". The invention can be applied to hair stylers, hair brushes with a power supply to the transformer with battery voltage, drying hoods or other hair care appliances. A use in air conditioners, humidifiers, air conditioning and the like is conceivable.
Weitere vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen genannt.Further advantageous developments of the invention are mentioned in the subclaims.

Die lonisationsvorrichtung umfasst eine Elektrode 12 mit einer Elektrodenspitze.The ionization device comprises an
Die lonisationsvorrichtung besteht weiterhin aus einer Hochspannungsquelle 11 - insbesondere einem Transformator - zur Bildung einer vorzugsweise negativen Hochspannung von vorzugsweise mindestens 2 kV und weniger als 6 kV, insbesondere weniger als 5 kV (je gemessenem mit Gigaohm des Meßgeräts an der Elektrodenspitze). Insbesondere eine gemessene Spannung von etwa 2,6 bis 3,8 kV an der Elektrodenspitze ist sehr vorteilhaft, wobei das Messgerät einen Widerstand von 1 Gigaohm besitzt. Das Transformatormodul wird vorzugsweise mit Netzfrequenz gespeist. Vorzugsweise liegt die Leerlaufspannung unterhalb von 7 kV.The ionization device further consists of a high voltage source 11 - in particular a transformer - for forming a preferably negative high voltage of preferably at least 2 kV and less than 6 kV, in particular less than 5 kV (each measured with gigaohm of the meter at the electrode tip). In particular, a measured Voltage of about 2.6 to 3.8 kV at the electrode tip is very advantageous, the meter has a resistance of 1 gigaohms. The transformer module is preferably fed at mains frequency. Preferably, the open circuit voltage is below 7 kV.
Grundsätzlich möglich ist auch ein Hochspannungsgenerator, der eine Kaskadenschaltung, ein Piezoelement oder ein anderes Erzeugungselement umfasst. Mindestens ist die Spannung aber 1000V, die hier bereits als Hochspannung bezeichnet wird. Bevorzugt werden negative lonen zum Entladen der Haare genutzt.In principle, it is also possible to use a high-voltage generator which comprises a cascade circuit, a piezoelectric element or another generation element. At least the voltage is 1000V, which is already referred to as high voltage. Preferably, negative ions are used to unload the hair.
Der Innenwiderstand der Hochspannungsquelle ist relativ hoch und beträgt insbesondere etwa 5 bis 20 Megaohm, insbesondere etwa 10 Megaohm, so dass ein Kurzschlußstrom von höchstens etwa 1,4 mA (z.B. 7kV/ 5 Megaohm), vorzugsweise etwa 0,3 bis 0,4 mA (z.B. 3 kV/10 Megaohm) möglich wäre. Dieser Strom ist für Personen ungefährlich, so dass selbst bei direkter Berührung der Elektrode 12 keine Gefahr ausgeht.The internal resistance of the high voltage source is relatively high and is in particular about 5 to 20 megohms, in particular about 10 megohms, so that a short circuit current of at most about 1.4 mA (eg 7kV / 5 megohms), preferably about 0.3 to 0.4 mA (eg 3 kV / 10 megohms) would be possible. This current is safe for people, so that even with direct contact with the
Der Generator kann auch im Griff 3 in einer Ausbuchtung der Gehäuseoberseite, oberhalb bzw. außerhalb des Heizluftstromes oder einer anderen Stelle integriert sein. Vorzugsweise ist er aber in einem ungeheiztem Bereich untergebracht.The generator can also be integrated in the
Die Elektrode 12 für einen lonenausstoss ist über ein Kabel 13, insbesondere ein Hochspannungkabel, mit der Hochspannungsquelle direkt verbunden. An der Elektrode 12 bildet sich ein elektrisches Feld aufgrund der Hochspannung. An einem spitzen Bereich 18 findet eine Erhöhung des elektrischen Feldes bzw. eine Erhöhung der Feldstärke (Feldkonzentration) statt.The
Die Hochspannungsquelle 11 ist bedarfsweise über einen Schalter 13 einschaltbar. Die Spannungsform ist pulsförmig oder als Gleich- oder Wechselspannung, z.B. als sinusförmige Spannung mit 50 Hz vorgesehen.The
Das Kabel 13 umfasst mindestens eine elektrische Isolierung 14 und mindestens einen elektrischen Leiter 15, der an einem freien Ende abisoliert ist, vorzugsweise sind 5 bis 15 mm abisoliert.The
Erfindungsgemäß ist die Ionisationselektrode 12 einstückig aus dem elektrischen Leiter 15 gebildet, wie
Das Kabel 13 ist genau zentrisch bis leicht exzentrisch zur Achse des Luftkanals befestigt. Höchstens ist die Elektrode 12 etwa 10 bis 15 mm zur Achse beabstandet. Im Wesentlichen ist sie immer noch zentrisch. Das Kabel 13 ist axial zum Luftstrom angeordnet und verläßt diese Ausrichtung erst in der Nähe des Griffs 3, wie
Insbesondere ist das Kabel 13 an einem Führungs- und/oder Befestigungselement, vorzugsweise aus elektrischem Isoliermaterial befestigt. Vorzugsweise ist das Kabel 13 an einem Heizelementträger, insbesondere an einer von mehreren Trägerplatten 6, insbesondere eines Mikanitkreuzes oder einer anderer Mikanitanordnung, vorzugsweise mit zwei bzw. vier oder drei bzw. sechs Platten 6, wie
Das Kabel 13 ist ferner über mindestens ein Halteelement 16 befestigt, das in der Nähe der Elektrode 12 und im Isolierten Leiterbereich angeordnet ist. Vorzugsweise ist ein zweites Halteelement 16 vorhanden, welches jedoch näher zum Griff 3 angeordnet ist.The
Die Platten 6 sind in der Nähe der Elektrode 12 ausgespart und bilden somit in Elektrodennähe einen Freiraum 17, wobei die Elektrode 12 in diesem Freiraum 17 frei liegt. Die Spitze der Elektrode 12 ist in dem Mikanitkreuz oder einer anderen Mikanitanordnung gelagert. Zwischen der Elektrodenspitze und den Trägerplatten 6 oder einem anderen Trägerelement ist ein Abstand von mindestens 5 mm, vorzugsweise mindestens 10mm vorhanden. Die Heizelemente und das Gehäuse 2 bilden ein Heizrohr.The
Um einen besseren lonenausstoss zu erreichen, wird der Leiter 15 schräg abgeschnitten, so dass eine Spitze 18 von vorzugsweise etwa 20° bis 60°, vorzugsweise etwa 30° bis 45° gebildet wird. Der Leiter 15 kann auch mehrfach von mehreren Seiten schräg abgeschnitten werden, so dass die Spitze 18 in der Mitte des Leiters liegt. Vorzugsweise ist die geschnittene Spitze in einem Ausblasbereich des Haartrockners 1 angeordnet und insbesondere im Heizkanal integriert.In order to achieve a better ion ejection, the
Der Leiterquerschnitt der Elektrode 12 beträgt abisoliert vorzugsweise etwa 0,8 bis 2 mm.The conductor cross section of the
Der Leiter 15 bzw. die Elektrode 12 kann eine einzige Ader umfassen, wie
Das Leiterende kann radial nach außen auseinander gefächert sein, wie
Besonders günstig sind Grate 21, die beim Abschneiden entstehen, wie
Besonders vorteilhaft ist es, dass nicht nur die Elektrodenspitze 18, sondern die gesamte Elektrode 12 frei liegt und/oder dass die Spitze direkt zum Luftaustritt zeigt, wie anhand der
Aber auch zusätzliche elektrische und mechanische Verbindungsstellen zwischen Elektrode und Kabel können zusätzliche parallele Impedanzen schaffen, die durch die einstückige Elektrodenausbildung verhindert wird.But additional electrical and mechanical connections between electrode and cable can create additional parallel impedances, which is prevented by the one-piece electrode formation.
Durch diese vorteilhafte kapazitätsarme Anordnung und der hier vorgesehenen Elektrode kann ein leistungsschwächerer Generator mit geringer Spannung und/oder geringerem Strom eingesetzt werden.This advantageous low-capacitance arrangement and the electrode provided here, a low-power generator with low voltage and / or lower power can be used.
Möglich ist auch, dass die Spitze durch Ultraschallschweißen geformt oder durch Funkenerosion gebildet wird. Auch kann das Leiterende bzw. die Elektrode gequetscht, gezogen oder aus einer Sollbruchstelle gebildet werden, so dass Feldkonzentrationspunkte entstehen. It is also possible that the tip is formed by ultrasonic welding or formed by spark erosion. Also, the conductor end or the electrode can be squeezed, pulled or formed from a predetermined breaking point, so that field concentration points arise.
