Abstract

The invention relates to a hand-held vacuum cleaner (1) which is driven by electric motor and has a suction mouthpiece (19) integrated in the bottom region. The cleaner is formed by a soft elastic, deformable housing (2) with a motor-driven fan (3, 20) integrated therein and a dust collection space (4). A dust filter (4a) is inserted between said two components, the covering (5) of the suction mouthpiece being flat, permeable to air and soft and the exhaust air being conducted via a hollow bar (12). <IMAGE>

Description

Die Erfindung betrifft ein elektromotorisch betriebenes Handsauggerät ohne Führungsstiel mit in den Bodenbereich integriertem Saugmundstück.The invention relates to an electric motor-operated hand-held suction device without a guide handle with a suction mouthpiece integrated into the base area.

Derartige Geräte sind bekannt. So sind Handsauggeräte zur Reinigung von Tischen o.ä bekannt, die ein Gehäuse aus Hartplastik und ein in den Bodenbereich integriertes Saugmundstück aufweisen. Der Antrieb erfolgt entweder über normale oder wiederaufladbare Batterien.Such devices are known. For example, hand suction devices for cleaning tables or the like are known which have a housing made of hard plastic and a suction mouthpiece integrated into the base area. It is powered by either normal or rechargeable batteries.

Allen bekannten Lösungen ist jedoch als Nachteil gemein, daß es sich hierbei lediglich um verkleinerte Staubsaugerausführungen handelt mit einer direkt an den Gerätekörper angeformten Saugdüse, wobei die Gehäuse aus Hartplastik bestehen und sich ausschließlich für ebene Flächen eignen.A disadvantage of all known solutions, however, is that these are only reduced-size vacuum cleaner designs with a suction nozzle molded directly onto the device body, the housings being made of hard plastic and being suitable only for flat surfaces.

Aufgabe der Erfindung ist es nun, unter Vermeidung der vorgenannten Nachteile, ein handliches kleines Handsauggerät zu schaffen, welches empfindliche räumliche Körper und auch Flächen einwandfrei reinigt, wobei der Staub vom Gerät aufgenommen und dieser unabhängig von der Gerätearbeitslage generell im Gerät verbleibt.The object of the invention is now, while avoiding the aforementioned disadvantages, to provide a handy small hand-held suction device which cleans sensitive spatial bodies and surfaces properly, the dust being absorbed by the device and generally remaining in the device regardless of the working position of the device.

Diese Aufgabe wird entsprechend des kennzeichnenden Teils des Anspruchs 1 gelöst.This object is achieved in accordance with the characterizing part of claim 1.

In den daran anschließenden Unteransprüchen sind vorteilhafte Ausgestaltungen der Erfindung beschrieben.Advantageous embodiments of the invention are described in the subsequent subclaims.

Die mit der Neuerung erzielbaren Vorteile liegen insbesondere darin, daß durch die Integration aller Baueinheiten in das elastisch verformbare Gehäuse eine äußerst kleine, handliche Bauweise realisieren läßt, mittels der man sowohl flächige, als auch räumliche Körper staubfrei und ohne Beschädigung reinigt.The advantages that can be achieved with the innovation are, in particular, that the integration of all structural units in the elastically deformable housing makes it extremely small and handy Construction can be realized by means of which both flat and spatial bodies can be cleaned dust-free and without damage.

Nachstehend ist ein Beispiel der Erfindung dargestellt, welches anhand der Zeichnungen näher erläutert ist.An example of the invention is shown below, which is explained in more detail with reference to the drawings.

Nach den Fig. 1 bis 2 besteht das Gerät (1) aus den drei Funktionseinheiten Motorgebläse (3), Filtersystem (4,4a) und Arbeitswerkzeug (2).1 to 2, the device (1) consists of the three functional units motor blower (3), filter system (4,4a) and working tool (2).

In dem Gehäuse (1) mit einer weichelastischen Haut (17) ist das Motorgebläse (3) in einer halbstarren bis starren, separat angeordneten Motoraufnahme (6) eingesetzt. Am Gehäuse (1) ist der Hohlbügel (12) angeformt, sodaß die Führungshand (18) des Benutzers derart positioniert ist, daß der Schwerpunkt (S) des Geräts (1) im Bereich des Handrückens (H) liegt.In the housing (1) with a soft elastic skin (17), the motor fan (3) is inserted in a semi-rigid to rigid, separately arranged motor mount (6). The hollow bracket (12) is molded onto the housing (1) so that the user's guide hand (18) is positioned such that the center of gravity (S) of the device (1) lies in the area of the back of the hand (H).

Vom Gehäuse (1) trennbar ist ein weichelastischer Filterraum (4), der gleichzeitig das Staubsaugermundstück (19) bildet, angeordnet. Zwischen diesem Filterraum (4) und dem Gebläse (20) ist ein Filter (4a) als Feinstaubfilter vorgesehen. Die Arbeitsfläche (21) des Staubsaugermundstücks (19) ist mit einer variablen weichen Polierabdeckung (5) versehen, welche als entsprechender Abscheider ausgewechselt wird.A flexible filter chamber (4), which simultaneously forms the vacuum cleaner mouthpiece (19), is arranged to be separable from the housing (1). A filter (4a) is provided as a fine dust filter between this filter space (4) and the blower (20). The working surface (21) of the vacuum cleaner mouthpiece (19) is provided with a variable soft polishing cover (5), which is replaced as a corresponding separator.

Die von der Motorgebläse-Einheit (3) erzeugte und vom Filter (4a) gereinigte Ausblasluft (22) wird durch den Hohlbügel (12) an die Umgebungsluft wieder abgegeben.The blow-out air (22) generated by the motor-blower unit (3) and cleaned by the filter (4a) is released again into the ambient air through the hollow bracket (12).

In den Fig. 3 bis 5 sind in einem elastischen Gehäuse (23) schlauchförmig ausgelegte Saugkanäle (8) geformt, welche in Richtung der weichen Polierabdeckung (5) Luftöffnungen (24) zeigen. Diese Saugkanäle (8) werden im zentralen Einlaß (25) zusammengeführt, welcher wiederum mittels eines Ventils (9) im Ruhezustand verschlossen ist.
Da das Zurückfallen des Staubes ausschließlich bei ausgeschaltetem Gerät - d.h., ohne Saugluftbewegung - erfolgt, wird das Ventil (9) über den Betriebsschalter (10) des Gerätemotors (26) gesteuert. Andere Betätigungsarten sind denkbar. Von Wichtigkeit hierbei ist lediglich, daß das Ventil bei ausgeschaltetem Gerät geschlossen ist.3 to 5, hose-shaped suction channels (8) are formed in an elastic housing (23), which show air openings (24) in the direction of the soft polishing cover (5). These suction channels (8) are brought together in the central inlet (25), which in turn is closed by a valve (9) in the idle state.
Since the dust falls back only when the device is switched off - ie without any suction air movement - the valve (9) is controlled via the operating switch (10) of the device motor (26). Other types of actuation are conceivable. The only important thing here is that the valve is closed when the device is switched off.

Entsprechend den Fig. 4 bis 7 ist zwecks ergonomischer Handhabung der Geräteschwerpunkt (5) unter dem Handrücken (H) angeordnet, indem der Hohlbügel (12) prismenförmig über den Handrücken (H) greift und höhenvariabel gestaltet ist. Die hierzu benötigte Federkraft (F) muß über dem Gerätegewicht (G) angesiedelt sein.4 to 7, for the purpose of ergonomic handling, the center of gravity (5) is arranged under the back of the hand (H) by the hollow bracket (12) reaching over the back of the hand (H) in a prismatic manner and being of variable height. The spring force (F) required for this must be located above the device weight (G).

Nach Fig. 2 bildet der Hohlbügel (12) eine Abluftführung (22) und beinhaltet Schalldämmaßnahmen (14) sowie den Difusor (16).2, the hollow bracket (12) forms an exhaust air duct (22) and contains sound insulation measures (14) and the diffuser (16).

Da das Gerät (1) für jede Art der Staubentfernung dient und auch Ecken -bzw. Randbearbeitung zulassen muß, ist das Gerät in Handrichtung mit einer Spitze (15) versehen, die vorzugsweise einen Spitzenwinkel von ca. 90° einnimmt.Since the device (1) is used for every type of dust removal and also corners or Edge processing must permit, the device is provided with a tip (15) in the direction of the hand, which preferably has a tip angle of approximately 90 °.

Im Bereich des Gebläseaustritts (27) zum Hohlbügel (12) hin ist ein elastischer Entdifusor (16) angeordnet, der den Auslaßluftstrom difusiert.In the area of the fan outlet (27) to the hollow bracket (12) there is an elastic dedifusor (16) which diffuses the outlet air flow.
