Description

Die Erfindung betrifft eine Vorrichtung für die Halterung und Zentrierung der Motor-Gebläseeinheit eines Lüfters, vorzugsweise eines Handhaartrockners.The invention relates to a device for holding and centering the motor-blower unit of a fan, preferably a hand hair dryer.

Bei Handhaartrocknern mit Radialgebläse und Universalmotor ist es bekannt (FR-A-1.440.087), den Motor für das Lüfterrad mit einer der beiden Gehäuseschalen fest zu verschrauben, wobei das Heizaggregat an anderer Stelle, nämlich im Luftaustrittskanal, angeordnet ist. Diese bekannte Anordnung von Motor, Lüfterrad und Heizaggregat hat den Nachteil einer aufwendigen Montage und eines relativ hohen Platzbedarfs.In the case of hand-held hair dryers with a radial fan and universal motor, it is known (FR-A-1.440.087) to screw the motor for the fan wheel firmly to one of the two housing shells, the heating unit being arranged at a different location, namely in the air outlet duct. This known arrangement of motor, fan wheel and heating unit has the disadvantage of complex assembly and a relatively large amount of space.

Weiterhin ist ein Handhaartrockner mit einem einen Universal-Motor umschließenden Lüfterrad und einem im Luftleitkanal angeordneten Heizregisters bekannt (FR-A-772.817), bei dem das Gehäuse des Gebläsemotors mit seinem hinteren Lagerschild, zusammen mit den abgebogenen Enden der rahmenförmigen, die Bürstenhalterungen aufweisenden Gehäuseteile auf einer Scheibe angeordnet sind, die ihrerseits über ein Gummiprofil zwischen zwei miteinander verschraubten Gehäusehälften eingespannt ist. Diese bekannte Lagerung der Motor-Geblaseeinheit hat im wesentlichen den Nachteil, daß der Motor zusammen mit der Scheibe auf den Handhaartrockner abgestimmt sein muß, wobei die Montage dieser Motor-Gebläseeinheit darüber hinaus auch mit Hilfe von Schrauben erfolgen muß, was vergleichsweise zeitaufwendig ist.Furthermore, a hand-held hair dryer with a fan wheel surrounding a universal motor and a heating register arranged in the air duct is known (FR-A-772.817), in which the housing of the blower motor with its rear bearing plate, together with the bent ends of the frame-shaped housing parts which have the brush holders are arranged on a disc, which in turn is clamped between two housing halves screwed together via a rubber profile. This known mounting of the motor-blower unit has the essential disadvantage that the motor must be matched to the hand-hair dryer together with the disk, and this motor-blower unit must also be assembled with the aid of screws, which is comparatively time-consuming.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die Motor-Gebläseeinheit, zusammen mit dem Heizaggregat, als eine Einheit auszubilden, wobei die Montage dieser Einheit am Aggregatgehäuse ohne Zuhilfenahme von Werkzeugen möglich sein soll.The present invention has for its object to form the motor-blower unit, together with the heating unit, as a unit, the assembly of this unit on the unit housing should be possible without the aid of tools.

Erfindungsgemäß wird dies dadurch erreicht, daß das Gehäuse des Motors zumindest teilweise von einem Trägerblech umgriffen ist, dessen sich beiderseits des Motors ersteckende Haltearme über das hintere Lagerschild des Motors hinaus verlängert sind, wobei die Haltearme mit ihren freien Enden in Schlitzen, Nuten oder an Leistern, die in oder an der Gehäusewand der Gehäuseschale vorgesehen sind, verankert sind und wobei zwischen dem hinteren Lagerschild des Motors und der mit Schlitzen, Nuten oder Leisten ausgestatteten Gehäuseschale eine Trägerplatte eingefügt ist, die das zylindrische, den Motor umschließende Heizaggregat hält.According to the invention this is achieved in that the housing of the motor is at least partially encompassed by a carrier plate, the holding arms of which extend on both sides of the motor are extended beyond the rear end shield of the motor, the holding arms with their free ends in slots, grooves or strips , which are provided in or on the housing wall of the housing shell, are anchored and a support plate is inserted between the rear bearing plate of the motor and the housing shell equipped with slots, grooves or strips, which holds the cylindrical, the motor surrounding heating unit.

Vorzugsweise liegt das Trägerblech am vorderen Lagerschild des Motors an, wobei die sich beiderseits dem etwa zylindrischen Motorgehäuse erstreckenden Arme den Motor an der Aggregat-Gehäusewand halten, wozu sich der Motor im Bereich der Verankerungsstellen mit seinem hinteren Lagerschild über die Trägerplatte an der Aggregat-Gehäusewand abstützt.Preferably, the carrier plate rests on the front bearing plate of the motor, the arms extending on both sides of the approximately cylindrical motor housing holding the motor on the unit housing wall, for which purpose the motor in the area of the anchoring points with its rear bearing plate over the carrier plate on the unit housing wall supports.

Mit Vorteil ist die das zylindrische Heizaggregat haltende Trägerplatte als gedruckte Leiterplatte ausgebildet, die mit einigen der für die Regelung und Steuerung des Motors und des Heizaggregats erforderlichen elektronischen Bauteilen versehen ist.The carrier plate holding the cylindrical heating unit is advantageously designed as a printed circuit board which is provided with some of the electronic components required for regulating and controlling the motor and the heating unit.

Um eine schwingungsfreie Verbindung zu schaffen, ist das Trägerblech in seinem mittleren, sich am vorderen Lagerschild des Motors abstützenden Teil als Federteller ausgebildet.In order to create a vibration-free connection, the carrier plate is designed as a spring plate in its central part, which is supported on the front end shield of the motor.

Die Erfindung läßt die verschiedensten Ausführungsmöglichkeiten zu. Eine davon ist in den anhängenden Zeichnungen wiedergegeben, und zwar zeigen

  • Fig. 1 den Längsschnitt durch einen Handhaartrockner mit der erfindungsgemäßen Motor-Gebläseeinheit,
  • Fig. 2 die Motor-Gebläseeinheit gemäß Fig. 1 in der Seitenansicht und teilweise im Schnitt,
  • Fig. 3 die Motor-Gebläseeinheit gemäß Fig. 2 in der Rückansicht und
  • Fig. 4 die Draufsicht auf die Schmalseite des Handhaartrockners, teilweise im Schnitt.
The invention allows for a wide variety of design options. One of them is shown in the attached drawings, showing
  • 1 shows the longitudinal section through a hand hair dryer with the motor-blower unit according to the invention,
  • 2 the motor-blower unit according to FIG. 1 in side view and partly in section,
  • Fig. 3 shows the motor-blower unit according to FIG. 2 in the rear view and
  • Fig. 4 is a top view of the narrow side of the hand hair dryer, partly in section.

Der Handhaartrockner besteht im wesentlichen aus den im Griffteil 1 angeordneten elektronischen Bauteilen 2, die auf einer Leiterplatte 3 angeordnet sind, den im Handgriff gelagerten und geführten Stellgliedern 4, 5, der den Motor 7, die Heizung 14 und das Lufterrad 8 umschließenden Motor-Gebläseeinheit 6, dem Luftleitkanal 9 und den beiden im Luftleitkanal 9 angeordneten Luftleitklappen 10 mit Ausblasgitter 11.The hand hair dryer consists essentially of the electronic components 2 arranged in the handle part 1, which are arranged on a circuit board 3, the actuators 4, 5 mounted and guided in the handle, the motor-blower unit surrounding the motor 7, the heater 14 and the air wheel 8 6, the air guiding duct 9 and the two air guiding flaps 10 arranged in the air guiding duct 9 with a blowout grille 11.

Die Motor-Gebläseeinheit 6 weist neben dem topfförmigen Lüfterrad 8 mit seinen Lüfterblättern 12, dem Motor 7, dem Trägerblech 13 und dem zylindrischen Heizaggregat 14 noch eine kreisscheibenförmige Trägerplatte 15 mit einigen auf ihr befestigten elektronischen Bauelementen 16 auf und schließlich noch ein schalenförmiges Luftleitblech 17, das zwischen dem Motor 7 und dem Heizaggregat 14 angeordnet ist.In addition to the cup-shaped fan wheel 8 with its fan blades 12, the motor 7, the carrier plate 13 and the cylindrical heating unit 14, the motor-blower unit 6 also has a circular disc-shaped carrier plate 15 with some electronic components 16 fastened to it and finally a bowl-shaped air baffle 17, which is arranged between the motor 7 and the heating unit 14.

Das den Motor umgreifende Trägerblech 13 stützt sich mit seinem mittleren Teil 18 am vorderen Lagerschild 19 des Motors 7 ab und zieht den Motor zusammen mit der Trägerplatte 15 gegen die Aggregatgehäusewand 20 (Fig. 1), an der das Trägerblech 13 mit seinen sich beiderseits des Motorgehäuses erstreckenden Armen 21, 21 a verankert ist.The support plate 13 encompassing the motor is supported with its central part 18 on the front bearing plate 19 of the motor 7 and pulls the motor together with the support plate 15 against the assembly housing wall 20 (FIG. 1), on which the support plate 13 is located on both sides of the Motor housing extending arms 21, 21 a is anchored.

Für die Montage der Motor-Gebläseeinheit 6 werden zunächst der Motor 7 und die Trägerplatte 15 miteinander verlötet, indem die Anschlußfahnen 27, 28 (Fig. 3) des Motors 7 durch Öffnungen in der Trägerplatte 15 hindurchgesteckt werden.For the assembly of the motor-blower unit 6, the motor 7 and the carrier plate 15 are first soldered to one another by inserting the connecting lugs 27, 28 (FIG. 3) of the motor 7 through openings in the carrier plate 15.

Da die Trägerplatte 15 als Leiterplatte ausgebildet ist (die Leiterbahnen sind nicht näher dargestellt), sind die Anschlußfahnen 27, 28 unmittelbar im Bereich des Durchtritts durch die Öffnungen verlötet. Nach der Montage des Motors 7 wird das schalenförmige Luftleitblech 17 mit Hilfe der Befestigungsfinger 29, 30 (Fig. 3) an der Trägerplatte 15 angeordnet. Anschließend läßt sich das Heizaggregat 14, welches als Mäanderheizung ausgeführt ist, über die Kontaktfahnen 31, 32, 33 (Fig. 3 und 2) mit der Trägerplatte verlöten. Vor der Befestigung des Lüfterrads 8 auf der Welle 34 des Motors 7 (Fig. 2) wird das U-förmig gebogene Trägerblech 13 über den Motor 7 (in Pfeilrichtung A) geschoben, wobei die als Haken 23, 24 ausgebildeten Enden der Arme 21, 21 a des Trägerblechs 13 die Trägerplatte 15 an der Aggregat-Gehäusewand 20 (Fig. 4) halten, und wobei die Haken 23, 24 hinter Leisten 35, die Teile der Gehäuseschale 36 des Handhaartrockner-Gehäuses sind, fassen.Since the carrier plate 15 is designed as a printed circuit board (the conductor tracks are not shown in more detail), the connecting tabs 27, 28 are directly in the region of the passage through the Soldered openings. After mounting the motor 7, the cup-shaped air baffle 17 is arranged on the carrier plate 15 with the aid of the fastening fingers 29, 30 (FIG. 3). Then the heating unit 14, which is designed as a meandering heater, can be soldered to the carrier plate via the contact tabs 31, 32, 33 (FIGS. 3 and 2). Before the fan wheel 8 is fastened to the shaft 34 of the motor 7 (FIG. 2), the U-shaped support plate 13 is pushed over the motor 7 (in the direction of arrow A), the ends of the arms 21, 21 a of the carrier plate 13 hold the carrier plate 15 on the unit housing wall 20 (FIG. 4), and the hooks 23, 24 behind strips 35, which are parts of the housing shell 36 of the hand hair dryer housing, grasp.

Da das Trägerblech 13 aus Stahlblech besteht (also aus einem federnden Werkstoff), und im Bereich des vorderen Lagerschilds 19, in seinem mittleren Teil 18 als Federteller ausgebildet ist, wird die Motor-Gebläseeinheit so fest gegen die Innenfläche 20 der Gehäuseschale 36 gezogen, daß einerseits eine schwingungsfreie und zuverlässige Verbindung des Teils 6 mit der Gehäuseschale 36 gegeben ist und andererseits eine Verbindung gebildet wird, die sich jederzeit und ohne die Verwendung von Werkzeugen wieder lösen läßt.Since the carrier plate 13 is made of sheet steel (i.e. from a resilient material), and in the area of the front bearing plate 19, in its central part 18, it is designed as a spring plate, the motor-blower unit is pulled so firmly against the inner surface 20 of the housing shell 36 that on the one hand there is a vibration-free and reliable connection of the part 6 to the housing shell 36 and on the other hand a connection is formed which can be released again at any time and without the use of tools.

Bei einer nicht näher dargestellten Ausführungsform der Erfindung sind an Stelle der Leisten (35) Schlitze oder Nuten an der Gehäuseschale (36) des Handhaartrockners vorgesehen, in die die Haken (23, 24) der Arme (21, 21 a) des Trägerblechs (13) einfassen.In an embodiment of the invention, not shown in detail, slits or grooves are provided on the housing shell (36) of the handheld hair dryer instead of the strips (35), into which the hooks (23, 24) of the arms (21, 21 a) of the carrier plate (13 ) border.

An Stelle des federnd ausgebildeten mittleren Teils (18) des Trägerblechs (13) kann auch ein federndes Zwischenglied vorgesehen sein, über das sich das Trägerblech (13) am Motor (7) abstutzt. Mit gleicher Wirkung kann auch ein federndes Zwischenglied zwischen der Trägerplatte (15) und der Aggregat-Gehäusewand (20) angeordnet sein.Instead of the resilient middle part (18) of the carrier plate (13), a resilient intermediate member can also be provided, by means of which the carrier plate (13) is supported on the motor (7). With the same effect, a resilient intermediate member can also be arranged between the carrier plate (15) and the unit housing wall (20).

Zweckmäßigerweise ist das federnde Zwischenglied als eine Scheibe aus elastischem Werkstoff, beispielsweise Gummi, ausgebildet.The resilient intermediate member is expediently designed as a disk made of elastic material, for example rubber.
