Description

"Die Erfindung geht aus von einem Haarwellgerät nach der Gattung des Anspruchs 1. Ein solches Haarwellgerät ist in der nicht vorveröffentlichten europäischen Patentanmeldung EP-A1 00 30 257 (benannte Vertragsstaaten, BE, CH, DE, FR, GB, IT, LI, NL, SE) beschrieben. Obwohl sich derartige Haarwellgeräte in der Praxis durchaus zufriedenstellend bewährt haben, kann sich der Einfluß der Wärmeentwicklung im Brennraum des Haarwellgerätes als äußerst nachteilig auf die Lebensdauer der die Zündvorrichtung speisenden Batterie auswirken. Eine mögliche Folge dieses Einflusses besteht darin, daß die Zündvorrichtung bereits nach kurzem Betrieb der Batterie nicht mehr zuverlässig arbeitet und somit eine Benutzung des Haarwellgerätes erschwert oder sogar unmöglich ist, zumal der Benutzer die Ursachen hierfür nicht ohne weiteres erkennen kann.""The invention is based on a hair waving device according to the preamble of claim 1. Such a hair waving device is described in the unpublished European patent application EP-A1 00 30 257 (designated contracting states, BE, CH, DE, FR, GB, IT, LI, NL , SE) Although such hair waving devices have proven themselves satisfactorily in practice, the influence of the heat development in the combustion chamber of the hair waving device can have an extremely disadvantageous effect on the service life of the battery feeding the ignition device Even after a short operation of the battery, the ignition device no longer works reliably, making it difficult or even impossible to use the hair waving device, especially since the user cannot readily identify the causes of this. "

Darüber hinaus ist ein Lockenwickler mit einer auf einer kontaktkatalytischen exothermen Reaktion beruhenden Heizvorrichtung bekannt (DE-A-15 57 290), der aus einem Brennstoffbehälter besteht, der an einem Ende eine Brennstoffaustrittsöffnung aufweist und eine an diesem Ende angeordnete Abdeckkappe, deren Innenraum eine Oxydations- oder Verbrennungskammer bildet, wobei in der Oxydationskammer das Oxydations-Katalysatormaterial angeordnet ist. Der Brennstsffbehälter und die Abdeckkappe sind mit Kanälen für die Zufuhr von gasförmigen Brennstoff und Verbrennungsluft aus der Brennstoffaustrittsöffnung bzw. aus der umgebenden Atmosphäre zu der Oxydationskammer ausgestattet. Die Abdeckkappe ist gegenüber dem Brennstoffbehälter unter Veränderung des freien Strömungsquerschnitts des Kanals für die Brennstoffzufuhr und/oder des Kanals für die Luftzufuhr einstellbar so, daß sich die von der Heizvorrichtung erzeugte Wärmemenge auf einfache Weise in weiten Grenzen regulieren läßt.In addition, a hair curler with a heating device based on a contact catalytic exothermic reaction is known (DE-A-15 57 290), which consists of a fuel container which has a fuel outlet opening at one end and a cover cap arranged at this end, the interior of which has an oxidation - Forms or combustion chamber, wherein the oxidation catalyst material is arranged in the oxidation chamber. The fuel tank and the cover cap are equipped with channels for the supply of gaseous fuel and combustion air from the fuel outlet opening or from the surrounding atmosphere to the oxidation chamber. The cap can be adjusted relative to the fuel tank by changing the free flow cross section of the channel for the fuel supply and / or the channel for the air supply so that the amount of heat generated by the heating device can be regulated within wide limits in a simple manner.

Bei einem weiter entwickelten Lockenwickler (DE-A- 2 040 003) ist die Brennstoff-Fördereinrichtung eine zwischen dem Brennstoffbehälter und der Brennkammer angeordneten Düse, durch die ein Strom bzw. Fluß gasförmigen Brennstoffs in die Brennkammer geleitet wird. Durch eine derartige Anordnung von Düse und Brennstoffbehälter soll die Steuerung der Fördermenge von Brennstoff . und Sauerstoff in die Brennkammer äußerst gleichmäßig und genau dosiert erfolgen. Der Katalysator besteht aus einem ersten Katalysator mit relativ langer Betriebslebensdauer und einem zweiten, aktiveren Katalysator mit kürzerer Betriebslebensdauer, wobei der zweite Katalysator einen Heizfaden aufweist, an dem zur Einleitung der Oxydation des gasförmigen Brennstoffes ein elektrischer Strom angeschlossen wird.In a further developed hair curler (DE-A-2 040 003), the fuel delivery device is a nozzle arranged between the fuel container and the combustion chamber, through which a current or flow of gaseous fuel is passed into the combustion chamber. Such an arrangement of the nozzle and the fuel tank is intended to control the delivery rate of fuel. and oxygen into the combustion chamber are extremely evenly and precisely metered. The catalyst consists of a first catalyst with a relatively long service life and a second, more active catalyst with a shorter service life, the second catalyst having a filament to which an electric current is connected to initiate the oxidation of the gaseous fuel.

Der Erfindung liegt die Aufgabe zugrunde, ein gattungsgemäßes Haarpflegegerät derart weiterzubilden, daß die Zündvorrichtung eine hohe Zündsicherheit und eine jahrelange Betriebsbereitschaft gewährleistet und daß insbesondere während des Betriebs des Haarpflegegerätes auftretende, schädliche Einflüsse auf die lebensdauer der Batterie weitestgehend vermieden werden. Diese Aufgabe wird durch ein Haarwellgerät mit den Merkmalen des Anspruches 1 gelöst."The invention has for its object to develop a generic hair care device in such a way that the ignition device ensures a high level of ignition security and years of operational readiness and that harmful influences on the life of the battery that occur during operation of the hair care device are largely avoided. This object is achieved by a hair waving device with the features of claim 1. "

In einer bevorzugten Ausführungsform ist der die elektrische Batterie mit dem Glühfaden ständig verbindende Stromleiter zumindest teilweise aus die Wärme schlecht leitendem Werkstoff gebildet. Die durch den Stromleiter auf die Batterie übertragene Wärme bleibt so relativ gering insbesondere auch weil der Stromleiter abschnittsweise durch die den wärmefluß-dämmende Kammer hindurchgeführt ist.In a preferred embodiment, the current conductor that permanently connects the electric battery to the filament is at least partially formed from a material that is poorly heat-conducting. The heat transferred to the battery by the current conductor remains relatively low, in particular because the current conductor is passed in sections through the chamber that insulates the heat flow.

Vorzugsweise ist der während des Zündvorgangs den Glühfaden mit der elektrischen Batterie verbindende Stromleiter zumindest teilweise rohrförmig ausgebildet. Über diesen rohrförmigen Stromleiter kann die Batterie während des Betriebs keinesfalls aufgeheizt werden, da nur während des Zündvorgangs eine direkte Verbindung über den rohrförmigen Stromleiter zwischen dem Glühfaden und der Brennkammer einerseits und der Batterie andererseits besteht.Preferably, the current conductor connecting the filament to the electric battery during the ignition process is at least partially tubular. The battery can in no way be heated via this tubular current conductor during operation, since there is only a direct connection via the tubular current conductor between the filament and the combustion chamber on the one hand and the battery on the other hand during the ignition process.

Mit besonderem Vorteil ist die elektrische Batterie zum Zwecke des Zündens über eine Bedientaste in Längsrichtung des Geräts gegen Federkraft verschiebbar in der Batteriekammer 96 gelagert, deren Gehäuse 64 aus elektrisch isolierendem Werkstoff gebildet ist, wobei das batterieseitige Ende des einen Stromleiters im Bereich der Batteriekammer spiralig zu einer flachen Druckfeder gebogen ist und am Batteriegehäuse anliegt, während das batterieseitige Ende des anderen vom Gehäuse der Batteriekammer gehaltenen Stromleiters über eine Kontaktfahne in die Batteriekammer hineinragt und während des Zündvorgangs den anderen Pol der elektrischen Batterie berührt.With particular advantage, the electric battery for the purpose of ignition can be displaced in the longitudinal direction of the device against spring force in the battery chamber 96, the housing 64 of which is formed from electrically insulating material, the battery-side end of a current conductor spiraling in the area of the battery chamber a flat compression spring is bent and rests on the battery housing, while the battery-side end of the other current conductor held by the housing of the battery chamber projects into the battery chamber via a contact lug and touches the other pole of the electric battery during the ignition process.

Die Erfindung faßt die verschiedensten Ausführungsmöglichkeiten zu. Eine davon ist in der anhängenden Zeichnung näher dargestellt, die einen Längsschnitt durch ein Haarwellgerät mit einer elektrisch arbeitenden Zündeinrichtung zeigt.The invention encompasses a wide variety of design options. One of them is shown in more detail in the attached drawing, which shows a longitudinal section through a hair waving device with an electrically operating ignition device.

Das Haarwellgerät besteht im wesentlichen aus dem zylindrischen Stabkörper 56, dem mit dem Stabkörper 56 verbundenen Brennstofftank 54 (der mit Brenngas gefüllt ist), dem den Brennstofftank nach hinten zu abschließenden Stopfen 24 mit Füllventil, dem den Stabkörper 56 nach vorne zu abschließenden Zünderträger 64, die insgesamt mit Z bezeichneten Zündvorrichtung, dem im Stabkörper gehaltenen insgesamt mit B bezeichneten Brennerkammer, dem mit 93 bezeichneten Verbrennungsraum, dem zwischen Stabkörper und Brennstofftank 54 angeordneten Grundkörper 50, auf dem die (nicht dargestellte) Haarklammer mit Bedientaste kippbar gelagert ist und schließlich dem Ventilglied 55 mit der aus den Teilen 51, 52, 55, 74,75,76,101,102,103,104,106,107,108 bestehenden insgesamt mit R bezeichneten Regeleinrichtung.The hair waving device consists essentially of the cylindrical rod body 56, the fuel tank 54 connected to the rod body 56 (which is filled with fuel gas), the plug 24 to be closed to the rear with a filling valve, the igniter carrier 64 to be closed to the front of the rod body 56, the ignition device denoted overall by Z, the burner chamber denoted overall by B held in the rod body, the combustion chamber denoted by 93, the between the rod body and the fuel tank 54 arranged base body 50, on which the hair clip (not shown) is tiltably mounted with the control button and finally the valve member 55 with the control device consisting of the parts 51, 52, 55, 74,75,76,101,102,103,104,106,107,108 designated with R .

Die dargestellte Zündvorrichtung Z arbeitet mit Hilfe einer elektrischen Batterie 57, die am freien Ende 58 des zylindrischen Stabkörpers 56 im Zünderträger 64 gehalten ist. Der Zünderträger 64 ist mit elektrischen Leitungen 61, 62, 63 bzw. einer Kontaktfeder 79 versehen, über die der Zündstrom von der Batterie 57 zum Glühfaden 60 gelangt. Um die elektrische Zündvorrichtung einzuschalten, wird die Bedientaste 59 gedrückt, d.h. sie wird in Gerätelängsrichtung gegen die Kraft der Kontaktfeder 79 bewegt, bis die Kontaktfahne 80 die Batterie 57 berührt bzw. an dieser fest anliegt. Der Batteriestrom fließt nun von der Batterie 57 über die Kontaktfeder 79, die elektrischen Leitungen 61, 62 bzw. die Kontaktfahne 80 und die rohrförmige elektrische Leitung 63 zum Glühfaden 60. Der Glühfaden 60 bringt nun, bei eingeschaltetem Stromkreis, das in die Brennkammer B einströmende Brennstoff/Luft-Gemisch zur Entzündung so, daß der katalytische Oxydationsprozess im Katalysator 77 in Gang kommt.The illustrated ignition device Z works with the aid of an electric battery 57, which is held in the igniter carrier 64 at the free end 58 of the cylindrical rod body 56. The igniter carrier 64 is provided with electrical lines 61, 62, 63 or a contact spring 79, via which the ignition current reaches the filament 60 from the battery 57. To turn on the electric igniter, the operation button 59 is pressed, i.e. it is moved in the longitudinal direction of the device against the force of the contact spring 79 until the contact lug 80 touches the battery 57 or bears firmly against it. The battery current now flows from the battery 57 via the contact spring 79, the electrical lines 61, 62 or the contact lug 80 and the tubular electrical line 63 to the filament 60. The filament 60 now brings the inflowing into the combustion chamber B when the circuit is switched on Fuel / air mixture for ignition so that the catalytic oxidation process in the catalyst 77 starts.

Der Katalysator 77 besteht aus einem strumpfartigen Gebilde aus Quarzwolle, die mit Platin beschichtet ist, wobei diese zu einem strumpfartigen Gebilde gepreßte Quarzwolle auf ein dünnwandiges Brennerrohr 78 aufgeschoben ist, das nach vorne zu, d.h. in Richtung auf die Zündvorrichtung Z zu, geschlossen ist und für den Brenngasaustritt mehrere Bohrungen 94, 95 aufweist.The catalytic converter 77 consists of a stocking-like structure made of quartz wool which is coated with platinum, said quartz wool pressed into a stocking-like structure being pushed onto a thin-walled burner tube 78 which is directed towards the front, i.e. in the direction of the ignition device Z, is closed and has a plurality of bores 94, 95 for the fuel gas outlet.

Der als Griffteil ausgebildete Brennstofftank 54 ist nach hinten zu durch einen Stopfen 24 abgeschlossen und wird vorne vom Ventilkörper 97 begrenzt. Der Ventilkörper 97 weist die Ventilbohrung 98 auf, in der das federbelastete Ventilglied 55 längsverschiebbar gelagert ist. Das Ventilglied 55 ist gegenüber der Ventilbohrung 98 mit Hilfe eines Dichtrings 99 abgedichtet. Das hintere Ende des Ventilglieds 55 weist eine Gummischeibe 76 auf, die in der dargestellten Position den Brennstoffaustritt über die Bohrung 101 und die Ventildüse 102 verschließt. Mit 75 ist ein Stopfen aus Sintermetall bezeichnet, in dem der Brennstoff verdampft, der vom Docht 74 zur Ventilöffnung 103 gefördert wird. Mit 70, 71, 72 und 73 sind Schaumstoffkörper bezeichnet, die den im Brennstofftank 54 befindlichen Brennstoff reinigen und ihn - insbesondere bei nur teilweise gefülltem Brennstofftank - zum Docht 74 transportieren.The fuel tank 54, which is designed as a grip part, is closed at the rear by a plug 24 and is delimited at the front by the valve body 97. The valve body 97 has the valve bore 98, in which the spring-loaded valve member 55 is mounted so as to be longitudinally displaceable. The valve member 55 is sealed off from the valve bore 98 by means of a sealing ring 99. The rear end of the valve member 55 has a rubber washer 76 which, in the position shown, closes the fuel outlet via the bore 101 and the valve nozzle 102. A plug made of sintered metal is designated by 75, in which the fuel evaporates, which is conveyed from the wick 74 to the valve opening 103. 70, 71, 72 and 73 denote foam bodies which clean the fuel in the fuel tank 54 and transport it to the wick 74, in particular when the fuel tank is only partially filled.

Das Ventilglied 55 wird von der Feder 104 in die Offen-Stellung geschoben (d.h. nach links bewegt so, daß das Brenngas bei 102 austreten kann), wenn der auf dem Bolzen 105 kippbar gelagerte Ventilhebel 106 vom Stellglied 107 mit Steuerkurve 108 gegen die Kraft der Reglerfeder 52 nach links verschwenkt wird (also sich von seiner Anlage am Reglerhebel 51 löst). Das Brenngas strömt in die Offen-Stellung von der Ventildüse 102 durch das Mischrohr 111 in das Brennerrohr 78 ein und von hier aus durch die Bohrungen 94, 95 zum Katalysator 77, wo es flammenlos verbrennt. Wenn die Temperatur in der Brennkammer B zu weit ansteigt, dann verkürzt die Reglerstange 53, die bei 112 mit dem Reglerrohr 113 verbunden ist, ihre Länge so weit, daß der auf dem Bolzen 105 kippbar gelagerte Reglerhebel 51 nach rechts bewegt wird so, daß das Ventilglied 55 gegen die Kraft der Feder 104 in die Geschlossen-Stellung verschoben wird. Solange der Ventilhebel 106 nach links verschwenkt bleibt, kann der Reglermechanismus 51, 53, 112, 113 den Gasaustritt aus der Ventildüse 102 frei regeln. In der in der Zeichnung dargestellten Position jedoch ist der Reglerhebel 51 blockiert (in seiner Geschlossen-Stellung).The valve member 55 is pushed by the spring 104 into the open position (ie moved to the left so that the fuel gas can escape at 102) when the valve lever 106, which is tiltably mounted on the pin 105, is actuated by the actuator 107 with the control cam 108 against the force of the Regulator spring 52 is pivoted to the left (thus detaches from its contact with the regulator lever 51). The fuel gas flows into the open position from the valve nozzle 102 through the mixing tube 111 into the burner tube 78 and from here through the bores 94, 95 to the catalyst 77, where it burns flamelessly. If the temperature in the combustion chamber B rises too far, the regulator rod 53, which is connected at 112 to the regulator tube 113, shortens its length so far that the regulator lever 51, which is tiltably mounted on the pin 105, is moved to the right so that that Valve member 55 is moved against the force of the spring 104 in the closed position. As long as the valve lever 106 remains pivoted to the left, the control mechanism 51, 53, 112, 113 can freely regulate the gas outlet from the valve nozzle 102. In the position shown in the drawing, however, the control lever 51 is blocked (in its closed position).

Der Zündträger 64 weist eine Batteriekammer 96 auf, in die die Batterie 57 einsetzbar ist. Durch eine Kammer 109, die den Wärmefluß vom Brennraum 93 zur Batterie 57 dämmt, ist die Batterie 57 bzw. die Batteriekammer 96 vom Brennraum 93 getrennt. Die Kammer 109 wird zur zusätzlichen Kühlung von der Außenluft durchströmt, wozu Öffnungen 110 vorgesehen sind, durch die die Umgebungsluft in die Kammer 109 einströmen kann. Der die elektrische Batterie 57 mit dem Glühfaden 60 ständig verbindende Stromleiter 61, 62 ist zumindestens teilweise aus schlecht wärmeleitendem Werkstoff hergestellt. Der den Glühfaden 60 während des Zündvorgangs mit den elektrischen Batterie 57 verbindende Stromleiter 63 ist zumindestens teilweise rohrförmig ausgebildet. Die elektrische Batterie 57 ist zum Zwecke des Zündens über eine Bedientaste 59 in Längsrichtung des Geräts gegen eine Federkraft verschiebbar in der Batterie gelagert. Das Gehäuse der Batteriekammer 96 ist aus elektrisch isolierendem Werkstoff gebildet, wobei das batterieseitige Ende des einen Stromleiters 61 im Bereich der Batteriekammer 96 spiralig gebogen ist und am Batteriegehäuse anliegt, während das batterieseitige Ende des anderen vom Gehäuse der Batteriekammer 96 gehaltenen Stromleiters 63 über eine Kontaktfahne 80 in die Batteriekammer 96 hineinragt. Die Stromleiter 61, 63 sind durch die, den Wärmefluß dämmende Kammer 109 hindurchgeführt und werden in diesem Abschnitt unmittelbar von der Umgebungsluft umspült.The ignition carrier 64 has a battery chamber 96 into which the battery 57 can be inserted. The battery 57 or the battery chamber 96 is separated from the combustion chamber 93 by a chamber 109 which insulates the heat flow from the combustion chamber 93 to the battery 57. For additional cooling, the outside air flows through the chamber 109, for which purpose openings 110 are provided through which the ambient air can flow into the chamber 109. The current conductor 61, 62 constantly connecting the electric battery 57 to the filament 60 is at least partially made of poorly heat-conducting material. The current conductor 63 connecting the filament 60 to the electric battery 57 during the ignition process is at least partially tubular. For the purpose of ignition, the electric battery 57 is mounted in the battery so as to be displaceable in the longitudinal direction of the device against a spring force via an operating button 59. The housing of the battery chamber 96 is formed from electrically insulating material, the battery-side end of the one current conductor 61 being spirally bent in the region of the battery chamber 96 and abutting the battery housing, while the battery-side end of the other current conductor 63 held by the housing of the battery chamber 96 via a contact tab 80 protrudes into the battery chamber 96. The current conductors 61, 63 are passed through the chamber 109 which insulates the heat flow and are directly surrounded by the ambient air in this section.
