Abstract

Es ist vorgesehen, ein Gehäuseoberteil eines Handstaubsaugers als getrenntes Bauelement als inneres separates Stützelement mit zur Aufnahme eines Motors auszubilden und die auftretenden Kräfte vom Reinigungsvorsatz auf das Gehäuseoberteil über einen Flansch weiterzuleiten.It is envisaged to form an upper housing part of a hand vacuum cleaner as a separate component as an inner separate support member for receiving a motor and forward the forces occurring from the cleaning attachment to the upper housing part via a flange.

Description

Die Erfindung bezieht sich auf ein Gehäuseunterteil für Handstaubsauger zur Verbindung mit einem Gehäuseoberteil, das eine Handhabe aufweist, wobei ein Motor und ein Anschlußstutzen für einen Saugvorsatz angeordnet sind und mit Schmutz beladene Luft von dem im Bodenbereich angeordneten Saugvorsatz über den Anschlußstutzen und eine Steigleitung einem Filterelement im oberen Bereich des Gehäuses zuführbar ist.The invention relates to a housing lower part for handheld vacuum cleaner for connection to an upper housing part having a handle, wherein a motor and a connecting piece are arranged for a Saugvorsatz and dirt laden air from the arranged in the bottom region suction attachment via the connecting piece and a riser a filter element in the upper part of the housing can be fed.

Anordnung dieser Art sind in unterschiedlichen Ausführungen bekannt. Es hat sich gezeigt, daß es in der Praxis Schwierigkeiten macht, die durch einen Anschlußstutzen eines Saugvorsatzes auftretenden Kräfte auf das Gerät überzuleiten, ohne das Erscheinungsbild zu beeinträchtigen. Es hat sich gezeigt, daß die bekannten Anordnungen anfällig für Beschädigungen sind.Arrangement of this type are known in different versions. It has been found that in practice makes it difficult to transfer the forces occurring through a connection piece of a suction attachment to the device without the appearance affect. It has been found that the known arrangements are susceptible to damage.

Die Aufgabe der Erfindung ist es, eine Kraftübertragung für einen Anschlußstutzen auf das Gerät zu ermöglichen und das Gehäuseunterteil in Form eines Baukastenelementes als multifunktionelles Geräteteil gleichzeitig zur Aufnahme von Funktionselementen heranzuziehen.The object of the invention is to enable a power transmission for a connecting piece to the device and to use the lower housing part in the form of a modular element as a multifunctional device part at the same time for receiving functional elements.

Die Lösung dieser Aufgabe erfolgt erfindungsgemäß dadurch, daß zur äußeren Hülle ein inneres Stützelement im Gehäuseunterteil gebildet ist, das an einem Endbereich den Anschlußstutzen trägt und an seinem anderen Endbereich formschlüssig über verbindungselemente mit dem Gehäuseoberteil verbunden ist und als Träger für Funktionselemente dient.The solution of this object is achieved according to the invention in that the outer shell an inner support member is formed in the lower housing part, which carries the connecting piece at one end and is positively connected at its other end portion via connecting elements with the upper housing part and serves as a support for functional elements.

Hierdurch werden Druckkräfte vom Anschlußstutzen auf das Gerät übertragen und ein inneres Stützelement gebildet, das unterhalb einer äußerlich sichtbaren Hülle durch die Rippen und Wandungen verstärkt wird.As a result, pressure forces are transmitted from the connecting piece to the device and formed an inner support member which is reinforced below an externally visible shell by the ribs and walls.

Eine vorteilhafte Ausbildung besteht darin, daß das innere Stützelement topfartig ausgebildet ist und an seiner geschlossenen Seite den Anschlußstutzen trägt.An advantageous embodiment is that the inner support member is pot-shaped and carries on its closed side the connecting piece.

Weiterhin wird vorgeschlagen, daß das Stützelement einen Aufnahmeraum für einen Saugmotor bildet.Furthermore, it is proposed that the support element forms a receiving space for a suction motor.

Eine weitere Verstärkung des inneren Stützelementes erfolgt erfindungsgemäß dadurch, daß der Aufnahmeraum für den Saugmotor Mittel zur Motorlagerung und Dichtung aufweist.A further reinforcement of the inner support element according to the invention is characterized in that the receiving space for the suction motor has means for engine mounting and gasket.

Es ist weiterhin vorgesehen, daß der Aufnahmeraum für den Motor Trennelemente für Saug- und Ausblasseite des Motors aufweist.It is further contemplated that the receiving space for the engine separating elements for suction and Ausblasseite the engine has.

Zusätzlich wird vorgeschlagen, daß der Aufnahmeraum für den Motor mit einem definierten Ausblasbereich verbunden ist.In addition, it is proposed that the receiving space for the engine is connected to a defined discharge area.

Weiterhin ist vorgesehen, daß das Stützelement den Sauganschluß als integriertes Element in Verbindung mit dem Anschlußstutzen aufweist.It is further provided that the support member has the suction port as an integrated element in connection with the connecting piece.

Ferner wird vorgeschlagen, daß das Stützelement mit seinem Sauganschluß zur lösbaren Aufnahme der Steigleitung für Nebensaugarbeiten als separat nutzbare Schlauchhandhabe ausgebildet ist.It is also proposed that the support member is formed with its suction port for releasably receiving the riser for secondary suction as a separately usable hose handle.

Der dargestellte Handstaubsauger besteht aus einem Reinigungsvorsatz 1, der über einen integrierten Stutzen 2 eines inneren Stützelementes 3 als Gehäuseunterteil von einer sichtbaren Hülle 4 umgeben ist. Über einen Flansch 5 ist das Stützelement 3 mit der Hülle 4 mit dem Gehäuseoberteil 6 als Filtergehäuse verbindbar und leitet hierbei die auftretenden Kräfte an das Filtergehäuse als Gehäuseoberteil 6 mit einer Handhabe 7 als Führungsstange über.The illustrated hand vacuum cleaner consists of a cleaning attachment 1, which is surrounded by an integrated socket 2 of an inner support member 3 as a lower housing part of a visible shell 4. About a flange 5, the support member 3 with the shell 4 with the Housing upper part 6 can be connected as a filter housing and in this case passes the forces occurring to the filter housing as the housing upper part 6 with a handle 7 as a guide rod.

Ein innenliegender Teil 8 des Stutzens 2 ist als Saugkanal ausgebildet, der als Sauganschluß 9 mit einem einzusetzenden Saugschlauch als Steigeleitung 10 zum Filter im Gehäuseoberteil 6 führt.An internal part 8 of the nozzle 2 is formed as a suction channel, which leads as suction port 9 with a suction hose to be used as riser 10 to the filter in the upper housing part 6.

Das innere Stützelement 3 dient gleichzeitig mit seiner Kavität 11 zur Aufnahme eines Motors 12 mit seinen entsprechenden Aufnahmen und Rippen. Gleichzeitig dient der Kavität 11 als Schalldämpfer und nimmt auch die entsprechenden Dichtungen 13 und Lagerungen für den Motor 12 zwischen Saug- und Ausblasseite auf. Im Verbindungsbereich zwischen inneren Stützelement 3 und Gehäuseoberteil 6 ist auch ein definierter Ausblasbereich 14 ausgebildet.The inner support member 3 serves simultaneously with its cavity 11 for receiving a motor 12 with its corresponding receptacles and ribs. At the same time the cavity 11 serves as a muffler and also receives the corresponding seals 13 and bearings for the motor 12 between the suction and discharge side. In the connecting region between the inner support element 3 and the upper housing part 6, a defined blow-out area 14 is also formed.

Das innere Stützelement 3 ist somit als kraftübertragendes, multifunktionales Bauelement ausgebildet, das die vom Reinigungsvorsatz 1 eingeleiteten Kräfte über den integrierten Stutzen auf das Gehäuseoberteil 6 als Filtergehäuse über den Flansch 5 weiterleitet.The inner support member 3 is thus designed as a force-transmitting, multifunctional component that forwards the forces introduced by the cleaning attachment 1 via the integrated connection piece to the housing upper part 6 as a filter housing via the flange 5.
