Description

Die Erfindung betrifft ein Handstück für ein Dampfreinigungsgerät mit einer Einleitung einer von einem Dampferzeuger zu dem Handstück führenden Dampfzuleitung, einer Dampfabgabeleitung und mit einem elektrischen Schalter zum Ein- und Ausschalten der Dampfzufuhr von dem Dampferzeuger zu dem Handstück.The invention relates to a handpiece for a steam cleaning device with an introduction of a steam supply line leading from a steam generator to the handpiece, a steam discharge line and with an electrical switch for switching the steam supply from the steam generator to the handpiece on and off.

Dampfreinigungsgeräte werden zunehmend auch im privaten Bereich eingesetzt. Dabei ist es notwendig, größtmögliche Sicherheitsvorkehrungen dafür zu treffen, daß durch den austretenden Dampf keine Verletzungen auftreten können.Steam cleaning devices are increasingly used in the private sector. It is necessary to take the greatest possible safety precautions so that no injuries can occur due to the escaping steam.

Bei bekannten Handstücken von Dampfreinigungsgeräten befindet sich an dem Handstück ein kleiner elektrischer Schiebeschalter, der durch ein verschiebbares Schaltelement auf der Oberseite des Handstücks betätigbar ist. In einer Einstellung des Schiebers ist die Dampfzufuhr eingeschaltet, in der anderen ausgeschaltet. Um den Schaltzustand zu ändern, muß der Benutzer jedesmal bewußt das Schiebestück des Schalters verschieben, und dies kann in ungünstigen Fällen dazu führen, daß die Dampfzufuhr unerwünschterweise aufrechterhalten bleibt, beispielsweise dann, wenn dem Benutzer das Handstück entfällt.In known handpieces of steam cleaning devices, there is a small electrical slide switch on the handpiece, which can be actuated by a sliding switching element on the top of the handpiece. The steam supply is switched on in one setting of the slide and switched off in the other. In order to change the switching state, the user has to consciously move the sliding piece of the switch each time, and in unfavorable cases this can lead to the undesired supply of steam is maintained, for example when the user does not need the handpiece.

Es ist Aufgabe der Erfindung, ein Handstück der gattungsgemäßen Art derart auszugestalten, daß eine unbeabsichtigte Dampfabgabe vermieden werden kann.It is an object of the invention to design a handpiece of the generic type in such a way that unintentional emission of steam can be avoided.

Dies wird bei einem Handstück der eingangs beschrieben Art erfindungsgemäß dadurch gelöst, daß in dem Handstück ein Handgriff beweglich gelagert ist, der gegen die Wirkung einer Feder in eine Arbeitsstellung bewegbar ist, in welcher der Schalter von dem Handgriff betätigt und die Dampfzufuhr eingeschaltet ist, und der bei entspannter Feder in einer Ruhestellung steht, in welcher der Schalter unbetätigt und die Dampfzufuhr ausgeschaltet ist. Bei einem solchen Handstück kann Dampf nur vom Dampferzeuger zugeführt und über das Handstück abgegeben werden, wenn der Benutzer dabei den Handgriff gegen die Wirkung der Feder verschiebt. Läßt der Benutzer den Handgriff los, so wird dieser unter der Wirkung der Feder zwangsläufig in die Ruheposition bewegt, in der die Dampfzufuhr zum Handstück unterbrochen wird. Insbesondere gilt dies dann, wenn der Benutzer das Handstück unbeabsichtigt fallen läßt.This is achieved according to the invention in a handpiece of the type described in the introduction in that a handle is movably mounted in the handpiece and can be moved against the action of a spring into a working position in which the switch is actuated by the handle and the steam supply is switched on, and which is in a rest position with the spring relaxed, in which the switch is not actuated and the steam supply is switched off. With such a handpiece, steam can only be supplied by the steam generator and released via the handpiece if the user moves the handle against the action of the spring. If the user lets go of the handle, it is inevitably moved under the action of the spring into the rest position, in which the steam supply to the handpiece is interrupted. This applies in particular if the user unintentionally drops the handpiece.

Bei einer besonders bevorzugten Ausführungsform ist vorgesehen, daß am Handstück ein Riegel verschiebbar gelagert ist, der zwischen einer den Handgriff in der Ruhestellung festlegenden und einer den Handgriff freigebenden Stellung bewegbar ist. Bei einer solchen Ausgestaltung kann der Handgriff nur dann gegen die Wirkung der Feder verschoben und damit die Dampfzufuhr eingeschaltet werden, wenn der Riegel in die den Handgriff freigebende Stellung verschoben ist, das heißt der Benutzer muß diesen Riegel bewußt in die Freigabestellung verschieben, um überhaupt eine Dampfzufuhr zu ermöglichen. Ein solcher Riegel wirkt als zusätzliche Sicherheitsmaßnahme, beispielsweise als Kindersicherung.In a particularly preferred embodiment it is provided that a latch is slidably mounted on the handpiece and can be moved between a position that fixes the handle in the rest position and a position that releases the handle. In such an embodiment, the handle can only be moved against the action of the spring and the steam supply can thus be switched on when the latch is moved into the position releasing the handle is, that is, the user must move this bar deliberately in the release position in order to allow a steam supply at all. Such a latch acts as an additional safety measure, for example as a child lock.

Die Handhabbarkeit des Handstücks wird verbessert, wenn der Handgriff an der Unterseite des Handstücks angeordnet ist.The handling of the handpiece is improved if the handle is arranged on the underside of the handpiece.

Insbesondere ist vorteilhaft, wenn der Handgriff ein Schwenkhebel ist.It is particularly advantageous if the handle is a swivel lever.

Bei einer bevorzugten Ausführungsform ist vorgesehen, daß der Handgriff ein Wandbereich eines das Handstück bildenden Gehäuses ist, der eine Öffnung an der Unterseite des Gehäuses verschließt. Das Gehäuse weist also an seiner Unterseite eine fensterartige Öffnung auf, in diese ist der Wandbereich eingepaßt, der den Handgriff bildet. Beispielsweise kann der Wandbereich schwenkbar am Gehäuse gelagert sein, so daß beim Ergreifen des Handstücks der Handgriff normalerweise zwangsläufig betätigt wird. Es ist dadurch für den Benutzer nicht notwendig, zur Betätigung der Dampfzufuhr das Handstück in ganz spezieller Weise zu erfassen oder gar umzugreifen, sondern beim normalen Erfassen des Handstücks wird automatisch auch der Handgriff betätigt.In a preferred embodiment it is provided that the handle is a wall area of a housing forming the handpiece, which closes an opening on the underside of the housing. The housing thus has a window-like opening on its underside, into which the wall area which forms the handle is fitted. For example, the wall area can be pivotally mounted on the housing so that the handle is normally inevitably actuated when the handpiece is gripped. It is therefore not necessary for the user to grasp the handpiece in a very special way or even to grip it to actuate the steam supply, but rather the handgrip is automatically actuated when the handpiece is gripped normally.

Es kann vorgesehen sein, daß der Handgriff einen Schaltvorsprung trägt, der einer Schaltnase eines im Handstück festgelegten Mikroschalters gegenüberliegt.It can be provided that the handle carries a switching projection which is opposite a switching lug of a microswitch fixed in the handpiece.

Ein besonders günstiger Aufbau ergibt sich dann, wenn die Feder eine Schraubenfeder ist, die in eine topfförmige Vertiefung des Handgriffs eintaucht und sich an einer Anlagefläche des Handstücks abstützt.A particularly favorable construction is obtained when the spring is a helical spring that dips into a pot-shaped recess in the handle and is supported on a contact surface of the handpiece.

Die nachfolgende Beschreibung einer bevorzugten Ausführungsform der Erfindung dient im Zusammenhang mit der Zeichnung der näheren Erläuterung. Es zeigen:

The following description of a preferred embodiment of the invention serves in conjunction with the drawing for a more detailed explanation. Show it:
Figure 1:

Figure 2:
an enlarged side view of the handpiece of Figure 1 in the region of the handle also in a partially broken view.

Das in der Zeichnung dargestellte Handstück 1 umfaßt zwei rohrförmige Abschnitte 2, 3, die zwischen sich einen Winkel von etwa 150° ausbilden. Das Handstück 1 wird umschlossen von einem Gehäuse, das sich aus zwei Halbschalen oder Gehäusehälften zusammensetzt, die längs der Längsmittelebene des Handstücks 1 voneinander getrennt sind und die im wesentlichen spiegelbildlich ausgeführt sind.The handpiece 1 shown in the drawing comprises two tubular sections 2, 3, which form an angle of approximately 150 ° between them. The handpiece 1 is enclosed by a housing which is composed of two half-shells or housing halves which are separated from one another along the longitudinal center plane of the handpiece 1 and which are essentially mirror images.

Am hinteren Ende mündet in das Handstück 1 eine Dampfzuleitung 4 ein, die das Handstück 1 mit einem in der Zeichnung nicht dargestellten Dampferzeuger verbindet. Diese Dampfzuleitung 4 führt zu einem Dosierventil 5 im vorderen Abschnitt 2 des Handstücks 1, der in der Zeichnung nur gestrichelt angedeutet ist. An das Dosierventil 5 schließt sich eine Dampfabgabeleitung 6 an, durch die vom Dampferzeuger zugeführter Dampf abgegeben werden kann.At the rear end, a steam feed line 4 opens into the handpiece 1, which connects the handpiece 1 to a steam generator (not shown in the drawing). This steam supply line 4 leads to a metering valve 5 in the front section 2 of the handpiece 1, which is only dashed in the drawing is indicated. A steam discharge line 6 connects to the metering valve 5, through which steam supplied by the steam generator can be discharged.

Im hinteren Abschnitt 3 des Handstücks 1 ist ein Mikroschalter 7 mit einer verschiebbaren Schaltnase 8 angeordnet, dieser Mikroschalter 7 ist über in der Zeichnung nicht dargestellte elektrische Leitungen ebenfalls mit dem Dampferzeuger verbunden. Der Mikroschalter schaltet im betätigten Zustand, also bei eingedrückter Schaltnase 8, die Dampfzufuhr ein und unterbricht diese im unbetätigten Zustand.In the rear section 3 of the handpiece 1, a microswitch 7 with a sliding switching lug 8 is arranged, this microswitch 7 is also connected to the steam generator via electrical lines, not shown in the drawing. The microswitch switches on the steam supply in the actuated state, that is to say when the switching lug 8 is pressed in, and cuts it off in the unactuated state.

An der Unterseite des Handstücks 1 weist das Gehäuse im Bereich des hinteren Abschnitts 3 eine fensterförmige Öffnung 9 auf, die durch einen diese Öffnung 9 vollständig ausfüllenden Handgriff 10 verschlossen ist. Dieser bildet im Bereich der Öffnung 9 einen Wandbereich 11 aus, der praktisch Teil des Gehäuses ist und der in seinen Abmessungen so gewählt ist, daß beim Ergreifen des Handstücks 1 im Bereich des hinteren Abschnitts 3 zumindest die vorderen Finger der Hand des Benutzers an diesem Wandbereich 11 anliegen.On the underside of the handpiece 1, the housing has a window-shaped opening 9 in the area of the rear section 3, which is closed by a handle 10 that completely fills this opening 9. This forms in the area of the opening 9 a wall area 11 which is practically part of the housing and which is chosen in its dimensions so that when gripping the handpiece 1 in the area of the rear section 3 at least the front fingers of the user's hand on this wall area 11 concerns.

Der Handgriff 10 ist am Handstück 1 um eine quer zur Längsachse des hinteren Abschnitts 3 verlaufende Drehachse 12 verschwenkbar gelagert, die Drehachse befindet sich dabei am hinteren Ende der Öffnung 9. An der Innenseite des Wandbereichs 11 taucht eine Schraubenfeder 12 in eine topfförmige Vertiefung 13 des Wandbereichs 11 ein, das andere Ende der Schraubenfeder 12 stützt sich an einer Anlagefläche 14 ab, die Teil des Handstücks 1 ist. Dadurch wird der Wandbereich 11 aus dem Inneren des Handstücks 1 nach außen verschwenkt, bis ein Anschlag 15 an dem freien Ende des Wandbereichs 11 an einem Vorsprung 16 im vorderen Abschnitt 2 des Handstücks 1 zur Anlage kommt. In dieser Lage ist der Wandbereich 11 mit dem übrigen Gehäuse ausgerichtet und verschließt somit die Öffnung 9 gleichsam als Teil des Gehäuses.The handle 10 is pivotally mounted on the handpiece 1 about an axis of rotation 12 extending transversely to the longitudinal axis of the rear section 3, the axis of rotation being located at the rear end of the opening 9 Wall area 11, the other end of the coil spring 12 is supported on a contact surface 14 which is part of the handpiece 1. Thereby the wall area 11 is pivoted outwards from the inside of the handpiece 1 until a stop 15 at the free end of the wall area 11 comes to rest on a projection 16 in the front section 2 of the handpiece 1. In this position, the wall area 11 is aligned with the rest of the housing and thus closes the opening 9 as part of the housing.

Gegen die Wirkung der Schraubenfeder 12 läßt sich der Wandbereich 11 in die Öffnung 9 hineinschwenken, wie dies in Figur 2 in strichpunktierten Linien dargestellt ist.Against the action of the helical spring 12, the wall area 11 can be pivoted into the opening 9, as shown in broken lines in FIG.

Im Inneren des Handstücks 1 trägt der Handgriff 10 einen Schaltvorsprung 17, der der Schaltnase 8 des Mikroschalters 7 unmittelbar gegenüberliegt. Wenn der Handgriff 10 unter der Wirkung der Schraubenfeder 12 nach außen geschwenkt ist, befindet er sich in einer Ruhestellung, in der der Schaltvorsprung 17 von der Schaltnase 8 des Mikroschalters 7 abgehoben ist, die Schaltnase 8 ist dann nicht eingedrückt. Wird der Handgriff 10 gegen die Wirkung der Schraubenfeder 12 eingeschwenkt, gelangt er in eine Arbeitsstellung. Dabei legt sich der Schaltvorsprung 17 an die Schaltnase 8 an und drückt diese in den Mikroschalter 7 ein, der Mikroschalter 7 wird also dadurch betätigt.In the interior of the handpiece 1, the handle 10 carries a switching projection 17 which is directly opposite the switching lug 8 of the microswitch 7. If the handle 10 is pivoted outwards under the action of the coil spring 12, it is in a rest position in which the switching projection 17 is lifted off the switching lug 8 of the microswitch 7, the switching lug 8 is then not pressed in. If the handle 10 is pivoted in against the action of the coil spring 12, it comes into a working position. The switching projection 17 rests on the switching lug 8 and presses it into the microswitch 7, the microswitch 7 is thus actuated thereby.

An der Unterseite des vorderen Abschnitts 2 des Handstücks 1 ist ein Schieber 18 verschiebbar gelagert, der in einer Endstellung mit einem Vorsprung 19 den Handgriff 10 hintergreift, wenn dieser in der Ruhestellung steht. Dadurch wird der Handgriff 10 in dieser Ruhestellung festgelegt, auch ein Druck auf den Wandbereich 11 führt dann nicht zu einem Einschwenken des Wandbereichs 11 in das Innere des Handstücks 1. In dieser Stellung des Schiebers 18 kann also die Dampfzufuhr nicht eingeschaltet werden, es ist zuerst notwendig, den Schieber 18 in eine Freigabestellung zu verschieben, in welcher der Vorsprung 19 den Wandbereich 11 nicht mehr hintergreift (wie in Figur 1 dargestellt).On the underside of the front section 2 of the handpiece 1, a slide 18 is slidably mounted, which in an end position engages behind the handle 10 with a projection 19 when it is in the rest position. As a result, the handle 10 is fixed in this rest position, and even pressure on the wall area 11 then does not result in the wall area 11 pivoting into the interior of the Handpiece 1. In this position of the slide 18, the steam supply cannot be switched on, it is first necessary to move the slide 18 into a release position in which the projection 19 no longer engages behind the wall area 11 (as shown in FIG. 1).
