Description

Die Erfindung betrifft ein Haarbehandlungsgerät mit einem Handgerät, das einen von einem Motor drehangetriebenen Haaraufrollzylinder und eine diesen senkrecht zu dessen Drehachse anströmende Heißluftdüse aufweist, bei dem an Ansaugöffnungen des Haaraufrollzylinders Unterdruck herrscht, der von einem Gebläse erzeugt wird, das in einem Gebläsekasten angeordnet ist und mit dem Handgerät über einen Schlauch in Verbindung steht, und bei dem die vom Gebläse über die Ansaugöffnungen des Haaraufrollzylinders angesaugte Luft nach dem Durchströmen des Gebläsekastens aus diesem austritt. Ein derartiges Haarbehandlungsgerät ist bekannt (EP-B1-0 052 325, DE-U-87 17 038.8). Bei diesem ist vorgesehen, daß die Kühlung des Gebläsemotors durch den über den Schlauch in den Gebläsekasten eintretenden und aus diesem über entsprechende Auslassöffnungen des Gebläsekastens in die Gebläsekasten-Umgebung austretenden Luftstrom gekühlt wird. Der zur Aufnahme eines Haares bzw. einer Haarsträhne an der Oberfläche des sich drehenden Haaraufrollzylinders benötigte Unterdruck wird also bei dem bekannten Haarbehandlungsgerät ähnlich wie bei einem Staubsauger erzeugt. Zum Trocknen der an der Oberfläche des Haaraufrollzylinders aufgenommenen bzw. aufgewickelten Haare wird durch im Gehäuse des Handgerätes vorgesehene Ansaugschlitze von der Umgebung her durch ein im Handgerät vorgesehenes weiteres Gebläse Luft angesaugt und über entsprechende Luftaufheizeinrichtungen zu der Heißluftdüse geleitet. Das bekannte Gerät besitzt den Nachteil, daß die zur wirksamen Trocknung erforderliche Trennung vom Unterdruck-Luftkreislauf und Trocknungs-Luftkreislauf eine aufwendige Bauweise des bekannten Haarbehandlungsgerätes mit sich bringt. Zur Luftversorgung der Heißluftdüse ist im Handgerät ein Gebläse erforderlich, welches aufgrund seines zusätzlichen Gewichtes die Handhabung des Handgerätes erschwert. Die frisierten Personen sind durch den mit hohen Drehzahlen laufenden Motor des Gebläses einer ständigen Geräuschbelästigung ausgesetzt, die deren Komfort entscheidend beeinträchtigt.The invention relates to a hair treatment device with a hand-held device, which has a hair roller cylinder driven by a motor and a hot air nozzle flowing perpendicularly to its axis of rotation, in which there is negative pressure at suction openings of the hair roller cylinder, which is generated by a fan which is arranged in a fan box and is connected to the handheld device via a hose, and in which the air sucked in by the blower via the suction openings of the hair roller cylinder emerges from the latter after flowing through the blower box. Such a hair treatment device is known (EP-B1-0 052 325, DE-U-87 17 038.8). It is provided that the cooling of the blower motor is cooled by the air flow entering the blower box via the hose and exiting from the blower box via corresponding outlet openings in the blower box environment. The negative pressure required to hold a hair or a strand of hair on the surface of the rotating hair reeling cylinder is thus generated in the known hair treatment device in a manner similar to that in a vacuum cleaner. To dry the hair taken up or wound up on the surface of the hair roller, air is sucked in from the environment through suction slots provided in the housing of the hand-held device by a further blower provided in the hand-held device and passed to the hot air nozzle via corresponding air heating devices. The known device has the disadvantage that the separation of the vacuum air circuit and drying air circuit required for effective drying entails a complex construction of the known hair treatment device. To supply air to the hot air nozzle, a blower is required in the hand-held device, which complicates handling of the hand-held device due to its additional weight. The hairdressers are exposed to constant noise pollution due to the high-speed motor of the blower, which significantly affects their comfort.

Aus der DE-PS 37 38 968 ist ein Haarbehandlungsgerät bekannt, bei dem ein geschlossener Luftkreislauf zwischen den Absaugöffnungen eines drehbaren Hohlkörpers und einer den Hohlkörper senkrecht anströmenden Ausblasdüse mit Luftausblasschlitzen vorgesehen ist. Die über die Absaugöffnungen des Hohlkörpers angesaugte Luft wird über eine flexible Schlauchleitung zur Saugseite eines Zentralgerätes geführt. Ein Radialventilator leitet die über die Schlauchleitung der Saugseite des Zentralgeräts zugeführte Luft der Druckseite des Zentralgeräts zu. Diese weist Auslaßstutzen auf, in denen jeweils ein Lufterhitzer angeordnet ist. Die in den Lufterhitzern erwärmte Luft wird über eine weitere Schlauchleitung den Luftausblasschlitzen der Ausblasdüse zugeführt. Dieses bekannte Haarbehandlungsgerät besitzt den Nachteil, daß es einen einzigen, in sich geschlossenen Luftkreislauf aufweist. Die von den auf den Hohlkörper aufliegenden Haaren abgegebene Feuchtigkeit gelangt über die Absaugöffnungen und die flexible Schlauchleitung zum Zentralgerät und wird dort durch die Lufterhitzer erwärmt. Die derart entstandene feuchtwarme Luft wird dann erneut über die Ausblasdüse auf die zu trocknenden Haare geblasen. Ein derartiger geschlossener Luftkreislauf wird schnell mit Feuchtigkeit gesättigt, so daß keine wirksame Trocknung mehr erfolgt.From DE-PS 37 38 968 a hair treatment device is known in which a closed air circuit is provided between the suction openings of a rotatable hollow body and a blow-out nozzle with air blow-out slots flowing vertically onto the hollow body. The air sucked in through the suction openings of the hollow body is led via a flexible hose line to the suction side of a central unit. A radial fan directs the air supplied via the hose line to the suction side of the central unit to the pressure side of the central unit. This has outlet connections, in each of which an air heater is arranged. The air heated in the air heaters is fed to the air outlet slots of the outlet nozzle via a further hose line. This known hair treatment device has the disadvantage that it has a single, closed air circuit. The moisture given off by the hair resting on the hollow body reaches the central device via the suction openings and the flexible hose line and is heated there by the air heaters. The moist, warm air thus created is then blown again onto the hair to be dried via the blow-out nozzle. Such a closed air circuit is quickly saturated with moisture, so that no effective drying takes place.

Der Erfindung liegt die Aufgabe zugrunde, die Handhabbarkeit und den Bedienungskomfort dieses Haarbehandlungsgerätes zu verbessern und zwar insbesondere dadurch, daß das verwendete Handgerät leichter wird, leichter im Handling ist und die Geräuschbelästigung der frisierten Person durch den am Handgerät vorgesehenen Motor für die Heißluftdüse entfällt. Ferner soll bei dem erfindungsgemäßen Haarbehandlungsgerät gewährleistet sein, daß keine Sättigung der zum Trocknen verwendeten Luft mit Feuchtigkeit auftritt.The invention has for its object to the manageability and ease of use of this hair treatment device improve and in particular in that the handheld device used is lighter, easier to handle and the noise of the hairdresser is eliminated by the motor provided on the handheld device for the hot air nozzle. Furthermore, it should be ensured in the hair treatment device according to the invention that there is no saturation of the air used for drying with moisture.

Erfindungsgemäß wird diese Aufgabe gemäß Anspruch 1 dadurch gelöst, daß ein vom Gebläse des Gebläsekastens aus der Gebläsekasten-Umgebung angesaugter, zur Kühlung des Gebläsemotors verwendeter Luftstrom anschließend über eine Warmluftleitung der im Handgerät vorgesehenen Heißluftdüse zugeführt wird.According to the invention this object is achieved in that an air stream sucked in by the blower of the blower box from the blower box environment and used to cool the blower motor is then fed via a warm air line to the hot air nozzle provided in the hand-held device.

Weitere Merkmale gemäß der Erfindung sind in den Ansprüchen 2-4 dargelegt.Further features according to the invention are set out in claims 2-4.

Ein derartiges Haarbehandlungsgerät hat folgende Vorteile:

  • (a) Der Motor für den Fön (Luftversorgung der Heißluftdüse) entfällt im Handgerät. Das Handgerät wird leichter.
  • (b) Die Geräuschbelästigung durch den beim Stand der Technik im Handgerät vorgesehenen Motor für den Fön entfällt. Diese Belästigung war besonders deshalb sehr gravierend, weil man aus Gründen der Gewichtsersparnis Motoren mit hohen Drehzahlen verwenden mußte, die wiederum ein besonders markantes und lautes Geräusch verursachen.
  • (c) Föne dieser Bauart (hohe Drehzahlen im Hinblick auf angestrebte Gewichtsersparnis) waren auch für professionellen Betrieb wegen,ihrer hohen Störanfälligkeit durch Verschleiß und Staubansatz ungeeignet. Damit, daß sie jetzt ersatzlos entfallen, wird das gesamte Gerät zuverlässiger.
  • (d) Der Energiebedarf wird erheblich geringer, da die Kühlluft für den Gebläsemotor im Gebläsekasten jetzt einer weiteren Nutzung, nämlich der Versorgung der Heißluftdüse im Handgerät zugeführt wird.
  • (e) Durch Anordnung des Motors für den Haaraufrollzylinder auf der dem Anschluß des Schlauches entgegengesetzten Seite des Handgerätes und ein besserer Gewichtsausgleich und damit ein besseres Handling erzielt.
  • (f) Das Handgerät kann kürzer ausgebildet werden; dies ergibt eine weitere Gewichtserleichterung sowie besondere Einsetzbarkeit z.B. im Nackenbereich von Frisuren. Der Handgriff kann ergonomischer gestaltet werden, weil in diesem BEreich die Hohlwelle und damit der Zwang zu einer rohrartigen runden Gestaltung entfällt.
  • (g) Die Stromersparnis gegenüber bekannten Geräten beträgt ca. 30%, die Gewichtsersparnis des Handgerätes ca. 200g.
Such a hair treatment device has the following advantages:
  • (a) The motor for the hair dryer (air supply to the hot air nozzle) is omitted in the handheld device. The handheld device becomes lighter.
  • (b) The noise nuisance caused by the motor provided for the hair dryer in the prior art is eliminated. This annoyance was particularly serious because you had to use high-speed motors to save weight, which in turn caused a particularly striking and loud noise.
  • (c) Hair driers of this type (high speeds with a view to saving weight) were also unsuitable for professional use because of their high susceptibility to failure due to wear and dust build-up. The fact that they are now no longer required makes the entire device more reliable.
  • (d) The energy requirement is considerably lower, since the cooling air for the blower motor in the blower box is now used for a further purpose, namely the supply of the hot air nozzle in the hand-held device.
  • (e) By arranging the motor for the hair roller cylinder on the side of the hand-held device opposite the connection of the hose and achieving a better weight balance and thus better handling.
  • (f) The handheld device can be made shorter; this results in a further weight reduction and special usability, for example in the neck area of hairstyles. The handle can be designed more ergonomically because the hollow shaft and thus the need for a tubular, round design are eliminated in this area.
  • (g) The power saving compared to known devices is approx. 30%, the weight saving of the hand-held device approx. 200g.

An embodiment of the invention and its advantageous developments is described below with reference to the accompanying drawings. They represent:

Figure 3
the blower box 2.

Figur 1 zeigt ein Frisier- und Haarbehandlungsgerät, daß durch ein Handgerät 1 und einen Gebläsekasten 2 gebildet wird. Eine Fiseuse oder ein Friseur handhabt das Handgerät, um damit einzelne Haarsträhnen H einer Person P aufzurollen, zu formen, zu entfeuchten und zu trocknen.Figure 1 shows a hairdressing and hair treatment device that is formed by a handheld device 1 and a blower box 2. A hairdresser or a hairdresser handles the hand-held device in order to roll up, shape, dehumidify and dry individual strands of hair H of a person P.

Wie aus Fig. 2 ersichtlich weist das Handgerät 1 einen Handgriff 10 auf, durch dessen Inneres hindurch sich ein Luftleitkanal 12 erstreckt. Am rechten Ende ist im Handgriff 10 eine Hohlwelle 11 drehbar gelagert. Auf der Hohlwelle 11 sitzt ein Zahnrad 13, welches von einem Motor 14 angetrieben wird. Der Motor 14 ist an ein Getriebe 15 angeflanscht und treibt die Welle 16, die mittels eines Zahnriemens 17 das Zahnrad 13 und damit die Hohlwelle 11 antreibt. Die aus Motor 14 und Getriebe 15 gebildete Einheit ist in einem Gehäuse 20 angeordnet, das mit dem Handgriff 10 verbunden ist. Im rechten Ende der Hohlwelle 11 steckt ein Haaraufrollzylinder 21, der vorne geschlossen, jedoch mit Öffnungen 22 versehen ist und sich mit der Hohlwelle 11 dreht.As can be seen from FIG. 2, the handheld device 1 has a handle 10, through the interior of which an air guiding channel 12 extends. At the right end, a hollow shaft 11 is rotatably mounted in the handle 10. On the hollow shaft 11 sits a gear 13 which is driven by a motor 14. The motor 14 is flanged to a gear 15 and drives the shaft 16, which drives the gear 13 and thus the hollow shaft 11 by means of a toothed belt 17. The unit formed from the motor 14 and the transmission 15 is arranged in a housing 20 which is connected to the handle 10. In the right end of the hollow shaft 11 there is a hair roller cylinder 21, which is closed at the front but has openings 22 and rotates with the hollow shaft 11.

Den mit Öffnungen 22 versehenen Längenbereich des Haaraufrollzylinders 21 abdeckend ist entlang derselben die Austrittsöffnung 25 einer Heißluftdüse 26 angeordnet. Die Austrittsöffnung 25 austretende Heißluft strömt senkrecht zur Achse A des Haaraufrollzylinders 21 aus. Die Heißluftdüse 26 ist um die Achse B kippbar am Luftkanal 27 angelenkt, der am Gehäuse 20 angeordnet ist.Covering the length region of the hair roller cylinder 21 provided with openings 22, the outlet opening 25 of a hot air nozzle 26 is arranged along the same. The outlet opening 25 exits hot air perpendicular to the axis A of the hair roller 21. The hot air nozzle 26 is articulated about the axis B on the air duct 27, which is arranged on the housing 20.

Der Heizdraht 29 befindet sich in der Warmluftleitung 28, die innerhalb des Gehäuses 20 in den Handgriff 10 hineingeführt ist und von der die erhitzte Luft dann in den Luftkanal 27 und von da in die Heißluftdüse 26 übertritt.The heating wire 29 is located in the hot air line 28, which is guided inside the housing 20 into the handle 10 and from which the heated air then passes into the air duct 27 and from there into the hot air nozzle 26.

Diese Anordnung - Heizdraht 29 in Strömungsrichtung weit weg von der Austrittsöffnung 25 der Heißluftdüse 26 - ermöglicht eine gute Durchmischung der Heißluft. Damit wird es ferner möglich, die Heißluftdüse 2-teilig auszubilden, damit man sie zur Reinigung leicht auseinandernehmen kann. Die Zweiteilung ist zeichnerisch nicht dargestellt; sie kann jedoch vorteilhafterweise entlang der sich parallel zur Ebene der Zeichnung erstreckenden Mittelebene der Heißluftdüse 26 erfolgen. Die Demontierbarkeit wird deshalb durch die beschriebene Anordnung des Heizdrahtes 29 ermöglicht, weil dann auch bei demontierter Heißluftdüse keine Gefahr der Berührung und/oder des Heizdrahtes 29 besteht.This arrangement - heating wire 29 in the direction of flow far away from the outlet opening 25 of the hot air nozzle 26 - enables good mixing of the hot air. This also makes it possible to design the hot air nozzle in two parts so that you can can be easily taken apart for cleaning. The division into two is not shown in the drawing; however, it can advantageously take place along the central plane of the hot air nozzle 26 which extends parallel to the plane of the drawing. The disassembly is made possible by the arrangement of the heating wire 29 described, because then there is no risk of contact and / or the heating wire 29 even when the hot air nozzle is disassembled.

Der Luftleitkanal 12 im Handgriff 10 steht mit einem Schlauch 30 in Verbindung. Die Warmluftleitung 28 steht mit einem weiteren Schlauch 31, der geringeren Querschnitt aufweist, in Verbindung. Der Schlauch 31 verläuft innerhalb des Schlauches 30.The air duct 12 in the handle 10 is connected to a hose 30. The hot air line 28 is connected to a further hose 31, which has a smaller cross section. The hose 31 runs inside the hose 30.

Im Gebläsekasten 2 wird durch ein Gebläse 35 im Raum 36, der mit dem Schlauch 30 in Verbindung steht, Unterdruck erzeugt. Dieser Unterdruck pflanzt sich über den Schlauch 30, den Luftleitkanal 12 im Handgriff 10, den Innenraum der Hohlwelle 11 bis in das Innere des Haaraufrollzylinders 21 fort, so daß er an den Öffnungen 22 wirksam wird. Gleichzeitig wird über den Schlauch 31 und die Warmluftleitung 28 angewärmte Luft dem Heißluftkanal 27 zugeführt und dort durch den Heizdraht 29 aufgeheizt. Die Heißluft tritt dann durch die Heißluftdüse aus.A negative pressure is generated in the blower box 2 by a blower 35 in the space 36, which is connected to the hose 30. This negative pressure propagates through the hose 30, the air duct 12 in the handle 10, the interior of the hollow shaft 11 into the interior of the hair roller cylinder 21, so that it becomes effective at the openings 22. At the same time, heated air is supplied to the hot air duct 27 via the hose 31 and the warm air line 28 and is heated there by the heating wire 29. The hot air then exits through the hot air nozzle.

Die Funktion des Gerätes ist derart, daß eine Haarsträhne H einer Person P durch den an den Öffnungen 22 des ansonsten außen glatten Haaraufrollzylinders 21 wirkenden Unterdruck aufgenommen und aufgewickelt wird. Im aufgewickelten Zustand dreht sich der Haaraufrollzylinder 21 weiter, während das Haar auf ihm gleitet. Gleichzeitig wird das Haar von der Heißluftdüse 26 angeströmt. Dabei wird über das Innere des Haaraufrollzylinders 21 und die Öffnungen 22 Luft abgesaugt wird. Man kann auf diese Weise sehr schnell das Haar aufrollen, entfeuchten, trocknen und formen.The function of the device is such that a strand of hair H of a person P through the openings 22 of the otherwise externally smooth hair roller cylinder 21 acting vacuum is taken up and wound up. In the wound state, the hair roller cylinder 21 continues to rotate while the hair is sliding on it. At the same time, the hot air nozzle 26 flows against the hair. Air is sucked out through the interior of the hair roller 21 and the openings 22. In this way you can roll up, dehumidify, dry and shape the hair very quickly.

Die Anwärmung bzw. Vorwärmung der Warmluft, die über Schlauch 31 und Warmluftleitung 28 zum Heißluftkanal 27 gelangt, erfolgt durch einen Luftstrom 40, der in den Gebläsekasten 2 durch Schlitze 41 eintritt und durch ein Förderrad 42 zur Kühlung des Gebläsemotors 50 in die an dessen Unterseite desselben vargesehenen Kühllufteinlaßschlitze 51 hineingedrückt wird. Dieser Luftstrom umströmt dann den sich im Betrieb erwärmenden Teil des Gebläsemotors 50 und tritt durch dessen Kühlluftauslaßschlitze 52 in die Kammer 53 ein, an die sich die Warmluftleitung 28 anschließt. Die besondere Idee, die sich die vorliegende Erfindung zu Nutze macht, liegt darin, die bei Kühlung des Gebläsemotors 50 im Gebläsekasten 2 sich erwärmende bzw. erwärmte Luft für den durch Heizeinrichtung 29 und Heißluftdüse 26 gebildeten Fön zu verwenden, so daß dieser selbst kein Gebläse mehr benötigt und außerdem dessen Heizeinrichtung sparsamer dimensioniert werden kann, da die Luft bereits durch Kühlung des Gebläsemotors 50 eine gewisse Vorwärmung erfahren hat.The warming or preheating of the warm air, which reaches the hot air duct 27 via hose 31 and warm air line 28, takes place by means of an air flow 40 which enters the blower box 2 through slots 41 and through a feed wheel 42 for cooling the blower motor 50 into the underside thereof the same seen cooling air inlet slots 51 is pressed. This air flow then flows around the part of the blower motor 50 that heats up during operation and enters the chamber 53 through its cooling air outlet slots 52, to which the warm air line 28 connects. The particular idea which the present invention makes use of is to use the air which warms up or heats up when the blower motor 50 is cooled in the blower box 2 for the hair dryer formed by the heating device 29 and the hot air nozzle 26, so that the latter itself is not a blower needed more and also its heating device can be dimensioned more economically, since the air has already been preheated to a certain extent by cooling the fan motor 50.

Das Gebläse 35 zur Erzeugung des Unterdrucks im Raum 36 und damit im Schlauch 30 wird ebenfalls durch ein Förderrad gebildet. Der abgesaugte Luftstrom tritt über Schlitze 60 aus dem Gebläsekasten 2 aus, wobei der Luftstrom vorher gezwungen wird, ein senkrecht stehendes Luftleitblech 61 zu umströmen, so daß sich Feuchtigkeit niederschlagen kann; das Kondenswasser tropft in einen in dem unteren Bereich des Gebläsekastens 2 einschiebbaren Kondenswassersammelbehälter 62.The fan 35 for generating the negative pressure in the space 36 and thus in the hose 30 is also formed by a feed wheel. The extracted air flow exits the blower box 2 via slots 60, the air flow being previously forced to flow around a vertical air baffle 61 so that moisture can precipitate; the condensed water drips into a condensed water collecting container 62 which can be pushed in in the lower region of the blower box 2.

Wie ersichtlich, befinden sich in Fig. 2 die Bauteile Motor 14, Getriebe 15, Hohlwelle 11 an dem einen Ende des Handgriffes 10, während an dem anderen Ende der Schlauch 30 befestigt ist. Dadurch entsteht also - betrachtet man das Handgerät 1 für sich alleine - ein gewisses Übergewicht auf der in Fig. 2 rechten Seite, das dem Gewicht des Schlauches 30 auf der anderen Seite entgegenwirkt.As can be seen, the components motor 14, gear 15, hollow shaft 11 are located in FIG. 2 at one end of the handle 10, while the hose 30 is fastened at the other end. As a result, if one considers the hand-held device 1 on its own, this creates a certain excess weight on the right-hand side in FIG. 2, which counteracts the weight of the hose 30 on the other side.

Wie bereits erwähnt, ist der Schlauch 31 für die Warmluft innerhalb des Schlauches 30 geführt, durch den die durch die Haarsträhnen H und die Öffnungen 22 hindurchgetretene Luft abgesaugt wird. Diese abgesaugte Luft ist aber vorher aus der Heißluftdüse 26 abgegeben worden, so daß sie, auch wenn sie sich bereits im Schlauch 30 befindet und dort zum Gebläsekasten 2 hingesaugt wird, noch eine gewisse Temperatur aufweist. Diese Temperatur ist höher als die der im Schlauch 31 zum Handgerät 1 hingeführten Luft. Es findet also noch in dem Schlauch 30 ein Wärmeaustausch statt und zwar dadurch, daß die im Schlauch 30 zum Gebläsekasten 2 hin strömende heiße Luft noch an die in der Gegenrichtung strömende vorgewärmte Luft im Schlauch 31 nach dem Gegenstromprinzip Wärme abgibt.As already mentioned, the hose 31 for the warm air is guided inside the hose 30, through which the air which has passed through the strands of hair H and the openings 22 is extracted. However, this extracted air has previously been discharged from the hot air nozzle 26 so that, even if it is already in the hose 30 and is sucked there to the blower box 2, it still has a certain temperature. This temperature is higher than that of the air carried in hose 31 to handheld device 1. There is therefore still heat exchange in the hose 30, specifically in that the hose 30 hot air flowing towards the blower box 2 still gives off heat to the preheated air flowing in the opposite direction in the hose 31 according to the countercurrent principle.

Die Vorwärmung der durch die Heißluftdüse 26 abgegebenen Luft durch den Gebläsemotor 50 kann der ersten Heizstufe der Heißluftdüse entsprechen, während bei Zuschaltung des Heizdrahtes 29 die zweite Heizstufe eingeschaltet ist. Auch insoweit tritt eine gerätebauliche Einsparung ein.The preheating of the air emitted by the hot air nozzle 26 by the blower motor 50 can correspond to the first heating stage of the hot air nozzle, while the second heating stage is switched on when the heating wire 29 is switched on. There is also a saving in terms of equipment in this respect.

Der Kaltlauf des Haaraufwickelzylinders ergibt sich, wenn der Heizdraht 29 abgeschaltet und das Ventil 66 in der Leitung 54, betätigt von einem Stellmotor 67, im Gegenuhrzeigersinn um 90° gedreht wird. Dann wird die Motorkühlluft am Gebläsekasten in's Freie abgeblasen. Das Aufrollen und Formen der Haare am Handgerät erfolgt ohne Fönen. Die Schaltung des Stellmotors G1 erfolgt zusammen mit Abschaltung des Heizdrahtes 29 in einer entsprechenden Stellung der Mehrfunktionstaste 65, die auch zur Einstellung der anderen Betriebsbedingungen dient, dabei verläuft die elektrische Leitung von der Mehrfunktionstaste 65 zum Stellmotor 61 im Schlauch 31, in dem trockene und im Verhältnis zur Luft im Schlauch 30 kühlere Luft geführt ist.The cold run-up of the hair winding cylinder occurs when the heating wire 29 is switched off and the valve 66 in the line 54, actuated by a servomotor 67, is rotated counterclockwise by 90 °. Then the engine cooling air is blown into the open at the blower box. The hair is rolled up and shaped on the handheld device without blow drying. The switching of the servomotor G1 takes place together with switching off the heating wire 29 in a corresponding position of the multifunction button 65, which also serves to set the other operating conditions, the electrical line from the multifunction button 65 runs to the servomotor 61 in the hose 31, in the dry and in Relationship to the air in the hose 30 cooler air is guided.
