Description

Die Erfindung betrifft einen batteriebetriebenen, über einen Ladesockel wiederaufladbaren Handstaubsauger gemäss dem Oberbegriff von Patentanspruch 1.The invention relates to a battery-operated hand-held vacuum cleaner that can be recharged via a charging base according to the preamble of patent claim 1.

Derartige Geräte sind bekannt CEP-A-0 008117 und auf dem Markt erhältlich. Sie weisen jedoch, was ihre Handhabung - insbesondere beim Lösen und Verbinden des Antriebsteils vom Staubbehälter - betrifft, erhebliche Nachteile auf. Das Lösen und Verbinden des Antriebsteils vom Staubbehälter ist jedoch zur Säuberung des Filters und des Staubbehälters unerlässlich.Such devices are known CEP-A-0 008117 and available on the market. However, they have considerable disadvantages with regard to their handling - in particular when loosening and connecting the drive part from the dust container. However, loosening and connecting the drive part from the dust container is essential to clean the filter and the dust container.

Bei bekannten Produkten wird das Lösen und Verbinden von Antriebsteil und Staubbehälter über den Rastknopf bewerkstelligt, der in einem vorderen Zwischenstück des Gerätes angebracht ist. Hierbei ist es nachteilig, dass der Rastknopf zu weit von dem Schalterknopf entfernt liegt, mit dem das Gerät ein und aus geschaltet wird und der sich vorteilhaft am vorderen Ende des Handgriffs befindet.In known products, the loosening and connection of the drive part and dust container is accomplished via the locking button, which is attached in a front intermediate piece of the device. It is disadvantageous here that the locking button is too far away from the switch button with which the device is switched on and off and which is advantageously located at the front end of the handle.

Ein weiterer Nachteil handelsüblicher Geräte betrifft deren Ladesockel, die speziell gestanzte und in sich gefederte Kontakte aufweisen, was eine teure und unrationelle Fertigung verursacht.Another disadvantage of commercially available devices concerns their charging bases, which have specially stamped and spring-loaded contacts, which causes expensive and inefficient production.

Es ist Aufgabe der vorliegenden Erfindung, die vorbeschriebenen Nachteile bei einem Handstaubsauger, der preisgünstig in seiner Herstellung ist, zu vermeiden.It is an object of the present invention to avoid the disadvantages described above in a hand-held vacuum cleaner that is inexpensive to manufacture.

Die Erfindung löst die Aufgabe bei durch den Handstaubsauger gemäss Patentanspruch 1. Erfindungsgemäss ist eine ergonomisch günstige Positionierung des Rastknopfes vorgesehen, nämlich dadurch, dass die Betätigungseinrichtung des Rastknopfes in unmittelbarer Nähe des am Griffteil angeordneten Schalterknopfes liegt und dass ferner der Ladesockel eine Kontaktierung aufweist, bei der handelsübliche, genormte Rohrniete als Kontakte verwendet sind.The invention solves the problem with the handheld vacuum cleaner according to claim 1. According to the invention, an ergonomically favorable positioning of the latching button is provided, namely in that the actuating device of the latching button is in the immediate vicinity of the switch button arranged on the handle part and that the charging base also has a contact the standard tubular rivets are used as contacts.

An der Stirnseite wird ein Antriebsteil des Handstaubsaugers verschlossen durch einen Spannring 43, der einstückig mit einem Lufteinlass 61, einem Labyrinth 62 und einem Haltering 63 mit den Rastnasen 55 für einen Filterring 41 ausgebildet ist (Fig. 1, 6, 7 und 8), und an dem eine Rastnase 44 für Staubbehälter 25 ausgebildet ist.On the front side, a drive part of the hand-held vacuum cleaner is closed by a clamping ring 43, which is formed in one piece with an air inlet 61, a labyrinth 62 and a retaining ring 63 with the latching lugs 55 for a filter ring 41 (FIGS. 1, 6, 7 and 8), and on which a latch 44 for dust container 25 is formed.

Zwei Halbschalen und 26 und 27 des Gehäuses des Antriebsteils enden an ihrer Vorderseite einstückig als federnde Haken 46, die in eine Ringnut 47 mit Schlitzen 64 des Spannringes 43 eingreifen und einrasten (Fig. 8 und 9).Two half-shells and 26 and 27 of the housing of the drive part end in one piece on their front side as resilient hooks 46 which engage and engage in an annular groove 47 with slots 64 of the clamping ring 43 (FIGS. 8 and 9).

Die beiden Halbschalen 26 und 27 umschliessen mit dem Spannring 43 das Sauggebläse bestehend aus einem Lüfterrad 10 und einem Motor 51, eine am Motor angelötete Leiterplatte 49 mit Ladekontakten 50, einen Schalter 59 mit einem Schalterknopf 37 un einen Zellenblock 48 mit Anschlüssen und Schaltlitzen. Ferner ist zwischen den Halbschalen 26 und 27 ein Rastknopf 36 mit einer Feder 58 angeordnet.The two half-shells 26 and 27 enclose with the clamping ring 43 the suction fan consisting of a fan wheel 10 and a motor 51, a circuit board 49 soldered to the motor with charging contacts 50, a switch 59 with a switch button 37 and a cell block 48 with connections and switch wires. Furthermore, a detent button 36 with a spring 58 is arranged between the half-shells 26 and 27.

Am Filterring 41 ist ein Filter 42 aus einem geeigneten, vorzugsweise waschbarem, luftdurchlässigem Filtermaterial angebracht. Der Filterring 41 mit dem Filter 42 wird mit einer Ringnut 65 auf den Haltering 63 des Spannringes 43 aufgesetzt. Beim Aufsetzen des Spannringes 41 ist durch die Gestaltung des bogenförmigen Halteringes 63 nur ein leichter Druck in axialer Richtung nötig um den Filterring 41 rastbar zu befestigen. Dabei kann der Haltering 43 wie in Fig. 8 bogenförmig aber auch trapez- oder dreieckförmig ausgebildet sein. Die Gestaltung des Spannringes 43 und des Filterringes 41 gewährleistet das problemlose Aufschnappen beider Ringe. Dabei können dieselben zueinander verdreht sein. Die Rastnasen 55 finden immer die richtige Einschnapp-Position, d.h. eine zugeordnete Einrastöffnung 56 im Filterring. Beim Lösen genügt ein Drehen des Filterringes 41; dabei wird der Haltering 63 mit den Rastnasen 55 in radialer Richtung zur Gerätemittelachse gedrückt. Die Rastnasen 55 kommen ausser Eingriff und ein leichtes Abziehen des Filterringes ist möglich.A filter 42 made of a suitable, preferably washable, air-permeable filter material is attached to the filter ring 41. The filter ring 41 with the filter 42 is placed with an annular groove 65 on the retaining ring 63 of the clamping ring 43. When the clamping ring 41 is put on, only a slight pressure in the axial direction is required due to the design of the arc-shaped retaining ring 63 in order to snap the filter ring 41 in place. In this case, the retaining ring 43 can be arch-shaped as in FIG. 8 but also trapezoidal or triangular. The design of the clamping ring 43 and the filter ring 41 ensures that both rings can be snapped on easily. The same can be twisted to each other. The detents 55 always find the correct snap-in position, i.e. an associated snap-in opening 56 in the filter ring. When loosening, rotating the filter ring 41 is sufficient; the retaining ring 63 with the locking lugs 55 is pressed in the radial direction of the device center axis. The locking lugs 55 come out of engagement and an easy removal of the filter ring is possible.

Der Staubbehälter 25 weist eine Düsenöffnung 66 auf, die durch eine sich in Saugrichtung öffnende elastische Klappe 67 verschlossen wird.The dust container 25 has a nozzle opening 66, which is closed by an elastic flap 67 that opens in the suction direction.

Der Staubbehälter 25 wird auf das Antriebsteil aufgesteckt und ist an der unteren Seite von der am Spannring 43 befindlichen Rastnase 44 festgehalten. An der oberen Seite wird der Staubbehälter vom Rastknopf 36 festgehalten, der mit seinem Rasthaken 45 in eine entsprechende Ausklinkung des Staubbehälters 25 eingreift und durch die Feder 58 in Eingriff gehalten wird. Zum Abnehmen des Staubbehälters 25 drückt man im Bereich der Feder 58 auf den Rastknopf 36, wodurch der Rasthaken 45 ausser Eingriff kommt und der Staubbehälter abgezogen werden kann.The dust container 25 is plugged onto the drive part and is held on the lower side by the detent 44 located on the clamping ring 43. The dust container is held on the upper side by the locking button 36, which engages with its locking hook 45 in a corresponding notch of the dust container 25 and is held in engagement by the spring 58. To remove the dust container 25, press the locking button 36 in the area of the spring 58, as a result of which the locking hook 45 disengages and the dust container can be removed.

Diese Anordnung zeichnet sich dadurch aus, dass der Rastknopf 36 nicht in einem vorderen Zwischenstück angebracht ist, das dem Spannring 43 des hier beschriebenen Staubsaugers entspricht, sondern im Antriebsteil integriert ist. Der wesentliche Vorteil dieser Anordnung besteht darin, dass der Rastknopf 36 unmittelbar vor dem Schalterknopf 37 sitzt und damit mit dem gleichen Daumen der Hand, die den Schalterknopf 37 betätigt, ohne Umgreifen erreicht werden kann.This arrangement is characterized in that the locking button 36 is not mounted in a front intermediate piece, which corresponds to the clamping ring 43 of the vacuum cleaner described here, but is integrated in the drive part. The main advantage of this arrangement is that the locking button 36 immediately before Switch button 37 sits and can be reached with the same thumb of the hand that operates the switch button 37 without reaching around.

Der Ladesockel, der in den Fig. 2, 3, 4 und 5 dargestellt ist, weist eine Kontaktierung auf, bei der statt speziell gestanzter und in sich gefederter Kontakte zwei handelsübliche genormte Rohrniete 29 als Kontakte verwendet werden, die durch ein dauerelastisches und elektrisch isolierendes Material 38 in federnder Position gehalten werden. Die Halterung der Rohrnieten 29 in einem Ladedorn 70 wird durch entsprechende Aussparungen im Ladedorn 70 bewerkstelligt, wobei die Sicherung gegen Herausfallen oben durch Haltezapfen 68 und unten durch an einem Ladesockel-Deckel 40 angebrachte Rippen 39 erreicht wird. Litzen 32 von einem Ladetrafo 33 sind dabei direkt am üblichen Bund der Rohrnieten angelötet. Für den Fall, dass der Ladesockel als Wandhalter verwendet wird, sind an zwei Haltevorprüngen 69 Rastnasen 35 angebracht, um dem Staubsauger einen sicheren Halt zu geben.The charging base, which is shown in FIGS. 2, 3, 4 and 5, has a contact, in which instead of specially punched and spring-loaded contacts, two commercially available standard tubular rivets 29 are used as contacts, which are provided by a permanently elastic and electrically insulating Material 38 are held in a resilient position. The tubular rivets 29 are held in a loading mandrel 70 by corresponding cutouts in the loading mandrel 70, the securing against falling out being achieved at the top by retaining pins 68 and at the bottom by ribs 39 attached to a charging base cover 40. Strands 32 from a charging transformer 33 are soldered directly to the usual collar of the tubular rivets. In the event that the charging base is used as a wall bracket, 69 latching lugs 35 are attached to two holding projections in order to give the vacuum cleaner a secure hold.

Die Saugluft gelangt durch den Filter 42 in den Lufteinlass 61 und wird vom Gebläserad 10 angesaugt. Durch die am Düsenrad des Gebläseraddeckels 53 axial nach hinten führende Krümmung wird die Luft schon vom Gebläserad nach hinten in Ausströmrichtung 61 aus dem Gehäuse geleitet (Fig. 10). Es werden dadurch Reibungsverluste durch im Gebläsegehäuse angebrachte Umleitkurven vermieden, die auf de Luftströmung bremsend wirken müssten.The suction air passes through the filter 42 into the air inlet 61 and is sucked in by the impeller 10. Due to the curvature leading axially backwards on the nozzle wheel of the fan wheel cover 53, the air is already directed backwards from the fan wheel in the outflow direction 61 (FIG. 10). This avoids friction losses due to bypass curves in the fan housing, which should have a braking effect on the air flow.

Durch konzentrisch im Spannring 43 ausgebildete Ringe 71 und einen am Gebläserad ebenfalls konzentrisch angebrachten Ring 54 entsteht im Zusammenwirken das Labyrinth 62, das einen unerwünschten Schlupf der Ansaugluft eindämmt und damit einen erhöhten Saugdruck bewirkt.By means of rings 71 formed concentrically in the clamping ring 43 and a ring 54 likewise concentrically attached to the impeller, the labyrinth 62 is created in cooperation, which restricts undesired slippage of the intake air and thus causes an increased suction pressure.
