Description

Die Erfindung betrifft einen Haartrockner mit vorzugsweise rohrförmigem Gebläsegehäuse und einem gegenüber dem Gebläsegehäuse verschwenkbaren, am Gebläsegehäuse angelenkten Griffteil.The invention relates to a hairdryer with a preferably tubular blower housing and a handle part pivotable relative to the blower housing and articulated on the blower housing.

Es sind bereits als Handgeräte ausgebildete Haartrockner bekannt (CH-PS 421.405), deren rohrförmige Gebläsegehäuse sich quer zur Gebläsegehäuselängsachse erstreckende Lagerblöcke aufweisen, an denen schwenkbare Griffteile befestigt sind. Die Griffteile sind dazu auf Achsen gelagert, die quer durch die Lagerblöcke hindurchgeführt sind.There are already known as hand-held hair dryers (CH-PS 421.405), the tubular blower housing of which extends transversely to the longitudinal axis of the blower housing and to which pivotable handle parts are attached. For this purpose, the handle parts are mounted on axles which are guided across the bearing blocks.

Weiterhin ist ein elektrisches Haartrockengerät mit Schonschalter bekannte (DE-OS 27 35 420), dessen rohrförmiges Gebläsegehäuse teilweise vom gabelförmig ausgebildeten Ende des Handgriffs umfaßt ist, wobei die Schwenkachse quer zur Längsachse des Gebläsegehäuses und durch dieses hindurch verläuft.Furthermore, an electric hair dryer with a protective switch is known (DE-OS 27 35 420), the tubular blower housing of which is partially encompassed by the fork-shaped end of the handle, the pivot axis extending transversely to the longitudinal axis of the blower housing and through it.

Schließlich ist ein elektrischer Haartrockner von pistolenförmiger Gestalt bekannte (DE-OS 25 28 056), dessen mit einem verschwenkbaren Handgriff versehenes Gehäuse aus zwei Schalenhälften gebildet ist. Die beiden Schalenhälften bestehen jeweils aus einem Gebläsemotoren-Gehäuseteil und einem Handgriff-Gehäuseteil, wobei der Handgriff-Gehäuseteil und der Gebläsemotoren-Gehäuseteil durch Ineinanderstecken im Schwerpunktbereich des Gebläsemotoren-Gehäuseteils miteinander verschwenkbar verbunden sind.Finally, an electric hair dryer of pistol-shaped shape is known (DE-OS 25 28 056), the housing of which is provided with a pivotable handle and is formed from two shell halves. The two shell halves each consist of a blower motor housing part and a handle housing part, the handle housing part and the blower motor housing part being pivotally connected to one another by being plugged into one another in the center of gravity of the blower motor housing part.

Die Erfindung liegt die Aufgabe zugrunde, einen Haartrockner so auszubilden, daß die äußeren Abmaße des Geräts bei bestimmter Leistung so klein wie möglich bemessen sind. Der Haartrockner soll darüber hinaus auch auf kleinstem Raum unterbringbar sein. Schließlich soll der Haartrockner trotz kleinster äußerer Abmessungen ein Gerät sein, das in mehreren Leistungsstufen arbeitet.The invention has for its object to provide a hair dryer so that the outer dimensions of the device are dimensioned as small as possible for certain performance. The hair dryer should also be able to be accommodated in the smallest space. After all, despite the smallest external dimensions, the hair dryer should be a device that works in several performance levels.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 nach der vorliegenden Erfindung gelöst. Weiter vorteilhafte Ausgestaltungsformen ergeben sich mit den Merkmalen der Unteransprüche. Dadurch, daß das Gebläsegehäuse mit einem sich quer zur Gehäuselängsachse erstreckenden, domartigen Gehäuseteil ausgestattet ist, welches den zur Gebläseluft-Temperaturregelung und zur Gebläsemotor-Drehzahlregelung erforderlichen, elektrischen Schaltkreis aufnimmt, ist es möglich, die äußeren Abmessungen des Gebläsegehäuses außerordentlich klein zu gestalten. Der gesamte Innenraum des hülsenförmigen Griffteils steht dabei der Aufnahme des elektrischen Stromversorgungskabels zur Verfügung, so daß sich bei beigeklapptem Griffteil eine insgesamt etwa quaderförmige Form für den Haartrockner ergibt.This object is solved by the features of claim 1 according to the present invention. Further advantageous embodiments result from the features of the subclaims. Characterized in that the blower housing is equipped with a dome-like housing part extending transversely to the longitudinal axis of the housing, which accommodates the electrical circuit required for blower air temperature control and blower motor speed control, it is possible to make the outer dimensions of the blower housing extremely small. The entire interior of the sleeve-shaped handle part is available for receiving the electrical power supply cable, so that when the handle part is closed, the overall shape of the hair dryer is approximately cuboid.

Ein weiterer Vorteil besteht auch darin, daß das elektrische Anschlußkabel ohne Knickschutztülle direkt an das Stromversorgungsteil im domartigen Gehäuseteil angeschlossen sein kann, so daß sich auch insoweit eine Platzersparnis ergibt. Ein Beschädigen des Stromversorgungskabels ist nämlich nicht möglich, da das Griffteil ein scharfes Abknicken des Kabels wirksam verhindert.Another advantage is that the electrical connection cable can be connected directly to the power supply part in the dome-like housing part without an anti-kink sleeve, so that space is also saved. Damage to the power supply cable is in fact not possible since the handle part effectively prevents the cable from kinking sharply.

Schließlich ist es von Vorteil, daß der elektrische Schalter im unmittelbaren Bereich der Finger der Griffwand am domartigen Gehäuseteil angeordnet ist. Auf diese Weise kann das Gerät bequem mit einer Hand bedient werden. Besondere stromführende Leitungen, die etwa bis an das Griffteil geführt sind, erübrigen sich durch die beschriebene Anordnung des elektrischen Schaltkreises.Finally, it is advantageous that the electrical switch is arranged in the immediate area of the fingers of the handle wall on the dome-like housing part. In this way, the device can be operated comfortably with one hand. Special current-carrying lines, which are guided up to the handle part, are unnecessary due to the arrangement of the electrical circuit described.

Die Neuerung läßt die verschiedensten Ausführungsformen zu. Eine davon ist in der anhängenden Zeichnung näher dargestellt, und zwar zeigen:

  • Figur 1 den Haartrockner mit beigeklapptem Griffteil und im Griffteil verstautem Stromversorgungskabel in perspektivischer Ansicht und
  • Figur 2 den Haartrockner gemäß Figur 1 zusammen mit dem zugehörigen Aufbewahrungsköcher, ebenfalls in perspektivischer Ansicht.
The innovation allows a wide variety of embodiments. One of them is shown in more detail in the attached drawing, which shows:
  • Figure 1 shows the hair dryer with the handle part folded and the power supply cable stowed in the handle part in a perspective view
  • Figure 2 shows the hair dryer according to Figure 1 together with the associated storage case, also in a perspective view.

Der Haartrockner weist ein im wesentlichen rohrförmiges, zweiteiliges Gehäuse 1, 2 auf, wobei sich quer zur Längsachse s des Gehäuses 1, 2 ein domartiges Gehäuseteil 3, 4, 5 erstreckt, dessen dem rohrförmigen Gehäuseteil 1, 2 des Haartrockners abgekehrtes Anschlußteil 5 im wesentlichen halbkugelig ausgebildet ist. Das domartige Gehäuseteil 3, 4, 5 ist mit einem Schalter 6 zum Ein- und Ausschalten der Motor-Gebläseeinheit des Handhaartrockners ausgestattet. Das Griffteil 7 ist hülsen- bzw. rohrförmig ausgebildet und weist an seinem geräteseitigen Ende gabelförmige Lageraugen 8 auf.The hair dryer has an essentially tubular, two-part housing 1, 2, a dome-like housing part 3, 4, 5 extending transversely to the longitudinal axis s of the housing 1, 2, the connecting part 5 of which is turned away from the tubular housing part 1, 2 of the hair dryer is hemispherical. The dome-like housing part 3, 4, 5 is equipped with a switch 6 for switching the motor-blower unit of the hand hair dryer on and off. The handle part 7 is sleeve-shaped or tubular and has fork-shaped bearing eyes 8 at its device-side end.

Die Lagerung des in Pfeilrichtung A abkippbaren Griffteils 7 besteht aus einem als Spannungsumschalter ausgebildeten bolzenförmigen Teil (Zapfen 9, 10). Die Spannungsumschaltung erfolgt durch Drehen des Zapfens 9, der zu diesem Zweck mit einem Schlitz 11 ausgestattet ist. Das hülsenförmige Griffteil 7 dient der Aufnahme des elektrischen Anschlußkabels 12 und verhindert ein Abknicken des in das domartige Gehäuseteil 3, 4, 5 unmittelbar eingeführten Anschlußkabels 12.The mounting of the handle part 7 which can be tilted in the direction of arrow A consists of a bolt-shaped part (pin 9, 10) designed as a voltage switch. The voltage is switched over by turning the pin 9, which is equipped with a slot 11 for this purpose. The sleeve-shaped handle part 7 serves to receive the electrical connection cable 12 and prevents the connection cable 12 which is inserted directly into the dome-like housing part 3, 4, 5 from kinking.

Das halbkugelige Anschlußteil 5 des domartigen Gehäuseteils 3, 4, 5 ist mit Vertiefungen 13, 14 bzw. 15, 16 versehen, die der Arretierung des Griffteils 7 nach dem Verschwenken in seine Betriebsposition um die Drehachse f (in Pfeilrichtung A) dienen, wobei entsprechend geformte Nocken (nicht näher dargestellt) auf der Innenwandung des Griffteils 7 im Bereich b bzw. c' vorgesehen sind.The hemispherical connecting part 5 of the dome-like housing part 3, 4, 5 is provided with recesses 13, 14 and 15, 16, respectively, which serve to lock the grip part 7 after pivoting into its operating position about the axis of rotation f (in the direction of arrow A), correspondingly shaped cams (not shown in detail) are provided on the inner wall of the handle part 7 in the area b or c '.

Wie Figur 2 zeigt, ist der Haartrockner mit in das Griffteil 7 eingestecktem Anschlußkabel 12 in einen Köcher 17 einschiebbar, der mit einer Öse 18 zur Aufhängung an einer Tragewand ausgestattet ist.As FIG. 2 shows, the hair dryer with the connecting cable 12 inserted into the handle part 7 can be pushed into a case 17 which is equipped with an eyelet 18 for hanging on a carrying wall.

Der Spannungsumschalter 9, 10, 11 besteht im wesentlichen aus einer Hülse, die auf eine Welle aufgeschoben ist, wobei Hülse und Welle um ihre Längsachse zueinander verdrehbar, jedoch nicht in ihrer Längsachse verschiebbar ausgebildet sind. Die Welle selbst ist fest im domartigen Teil 3, 4, 5 verankert, wobei die Lageraugen 8 soweit federnd ausgebildet sind, daß sie bei der Montage des Gerätes über den Zapfen 9 und den Zapfen 10 schiebbar sind und sich dann dort den Zapfen 9 umgreifend verankern.The voltage switch 9, 10, 11 consists essentially of a sleeve which is pushed onto a shaft, the sleeve and shaft being rotatable relative to one another about their longitudinal axis, but not are designed to be displaceable in their longitudinal axis. The shaft itself is firmly anchored in the dome-like part 3, 4, 5, the bearing eyes 8 being designed so resiliently that they can be pushed over the pin 9 and the pin 10 during assembly of the device and then anchoring the pin 9 there .
