Definitions
- the invention relates to a hand-held spray gun for a high-pressure cleaning device with a supply line for a cleaning medium under high pressure and with an outlet opening which is connected to the supply line via a throttle point with a variably adjustable cross section.
- This object is achieved in that an actuating element for changing the cross section of the throttle point and a display are arranged on the hand spray gun, which indicates the position of the actuating element relative to the hand spray gun.
- the change in position of the actuating element is therefore used to make a display on the hand spray gun itself, on which the operator can read the respective throttling effect.
- This throttling effect is a measure of the amount of liquid dispensed on the one hand and a measure of the temperature of the dispensed liquid on the other hand, so that the user can be given information about both the amount of dispensed liquid and its temperature by means of a corresponding double scale. No complicated measuring devices are necessary for this, but an appropriate display can be made solely by the respective position of the actuating element.
- the display on the hand spray gun is arranged above the outlet opening, since the operator can see such an display particularly well in this area.
- the actuating element is a sleeve surrounding the outlet opening and rotatable about its longitudinal axis.
- the sleeve carries a transparent window through which a part of the hand spray gun receiving the outlet opening is visible. It can be, for example, a flow channel through which the cleaning liquid flows.
- the hand spray gun has a transparent window through which the sleeve is visible.
- the window and the scales or marking elements interacting through this visible part carry the operator, which provide the operator with the desired information about the dispensing quantity and temperature. It is particularly advantageous if two scales are provided, namely a scale for the quantity dispensed and a scale for the temperature, so that the operator can simultaneously read these different values, which are influenced in the same way by the position of the actuating element.
- a slide is arranged displaceably along the bore, which narrows the flow channel to different degrees in different positions in the bore and by means of the actuating element is displaceable in the bore.
- the actuating element is a sleeve, it is advantageous if it carries a slideway which is eccentric to its axis of rotation and on which the slide rests. In this way, a structurally particularly simple, non-bulky and nevertheless easily operable setting for the throttle in the hand-held spray gun is obtained, which at the same time enables the desired display of the values achieved by the setting.
- the hand-held spray gun 1 which is only partially shown in the drawing, comprises a handle part 2 and a housing 3 in which there are flow fittings.
- a supply line for a cleaning medium in the form of a flexible high-pressure hose opens into the handle part 2, this is not shown in the drawing. It leads to a flow channel 4, which is arranged in the interior of the housing 3 and ends in a step-widening manner in an outlet opening 5, onto which, for example, a spray lance (not shown in the drawing) can be screwed.
- a sleeve 6 is arranged on the flow channel 4 so as to be rotatable about its longitudinal axis. It carries on its inside a slide 7 which is eccentric to its axis of rotation and against which a slide 8 bears on both sides (FIG. 3) and which seals it in a bore 9 passing through it in a direction transverse to the longitudinal direction of the flow channel 4 and is mounted for longitudinal displacement.
- the slide 8 passes through the flow channel 4
- the latter has a part 10 completely filling the bore 9 and an adjoining circumferential groove 11, ie in the region of the circumferential groove 11 there is between the slide 8 and the inner wall of the bore 9 an annular space 12 surrounding the slide 8.
- the flow channel 4 can be completely blocked, namely when the part 10 of the slide 8 with a large diameter is inserted into the flow channel 4.
- a complete opening of the flow channel 4 is obtained, however, when the area of the annular space 12 is inserted into the flow channel 4, with intermediate positions of the slide 8, a stepless cross-sectional narrowing of the flow channel 4 between these two extreme values is obtained.
- the slide 8 is simply moved by rotating the sleeve 6 and the eccentric slideway 7 connected to it.
- the front end 13 of the sleeve 6 engages under a cylindrical cap 14, which is rotatably mounted on the flow channel 4 and has a rectangular recess 15 in its top, in which a transparent window 16 is located.
- the front part of the sleeve 13 arranged below the cap 14 can be seen through this window 16; the sleeve 13 carries in this area a marking element 17, which is recorded on the outside of the sleeve in a helical manner and concentric to the axis of rotation of the sleeve 13 and which passes through the window 16 is visible through it and, when the sleeve 6 is rotated relative to the flow channel 4, shifts in the central region of the window 16 in the longitudinal direction of the flow channel 4.
- Scales 18, 19 are recorded on the window 16 on both sides of the center, between which a transparent area 20 remains, through which the marking element 17 can be seen.
- the two scales are arranged in opposite directions, one scale indicates the amount of liquid dispensed, the other the temperature, both sizes are opposite. This enables the operator to read directly on the two scales how large the amount of liquid currently dispensed is and what temperature it is. These values can be adjusted in a precisely observable manner simply by turning the sleeve.
Abstract
Description
Die Erfindung betrifft eine Handspritzpistole für ein Hochdruckreinigungsgerät mit einer Zufuhrleitung für ein unter hohem Druck stehendes Reinigungsmedium und mit einer Auslaßöffnung, die mit der Zufuhrleitung über eine Drosselstelle mit variabel einstellbarem Querschnitt verbunden ist.The invention relates to a hand-held spray gun for a high-pressure cleaning device with a supply line for a cleaning medium under high pressure and with an outlet opening which is connected to the supply line via a throttle point with a variably adjustable cross section.
Es ist bekannt, derartige Handspritzpistolen zu verwenden, um durch die unterschiedliche Drosselwirkung die Menge und den Druck der abgegebenen Reinigungsflüssigkeit zu variieren. Normalerweise sieht die Bedienungsperson an der Größe des abgegebenen Reinigungsflüssigkeitsstrahles, welche Drosselstellung gewählt ist, eine sehr genaue Beobachtung ist dabei jedoch nicht möglich. Insbesondere bei beheizten Hochdruckreinigungsgeräten ergibt sich das Problem, daß wegen der in der Regel konstanten Heizleistung bei Abnahme der abgegebenen Flüssigkeitsmenge die Temperatur ansteigt, so daß es wünschenswert wäre, deren Bediener hier genauere Informationen an die Hand zu geben.It is known to use such hand-held spray guns in order to vary the quantity and pressure of the cleaning liquid dispensed by the different throttling action. Normally, the operator can see which throttle position is selected from the size of the cleaning liquid jet, but very precise observation is not possible. The problem arises in particular in the case of heated high-pressure cleaning devices that the temperature rises due to the generally constant heating power when the amount of liquid dispensed decreases, so that it would be desirable to provide the operator with more precise information here.
Es ist Aufgabe der Erfindung, eine Handspritzpistole der eingangs beschriebenen Art derart auszubilden, daß die Bedienungsperson über die abgegebene Flüssigkeitsmenge und nach Möglichkeit auch über deren Temperatur informiert ist.It is an object of the invention to design a hand-held spray gun of the type described at the outset in such a way that the operator is informed about the amount of liquid dispensed and, if possible, also about its temperature.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß an der Handspritzpistole ein Betätigungselement für die Querschnittsveränderung der Drosselstelle und eine Anzeige angeordnet sind, die die Stellung des Betätigungselements relativ zur Handspritzpistole anzeigt.This object is achieved in that an actuating element for changing the cross section of the throttle point and a display are arranged on the hand spray gun, which indicates the position of the actuating element relative to the hand spray gun.
Es wird also die Positionsänderung des Betätigungselementes ausgenützt, um an der Handspritzpistole selber eine Anzeige vorzunehmen, an der die Bedienungsperson die jeweilige Drosselwirkung ablesen kann. Diese Drosselwirkung ist ein Maß für die abgegebene Flüssigkeitsmenge einerseits und ein Maß für die Temperatur der abgegebenen Flüssigkeit andererseits, so daß durch eine entsprechende Doppelskale dem Benutzer sowohl über die Menge der abgegebenen Flüssigkeit als auch über deren Temperatur Auskunft gegeben werden kann. Dazu sind keine komplizierten Meßgeräte notwendig, sondern es kann allein durch die jeweilige Position des Betätigungselementes eine entsprechende Anzeige vorgenommen werden.The change in position of the actuating element is therefore used to make a display on the hand spray gun itself, on which the operator can read the respective throttling effect. This throttling effect is a measure of the amount of liquid dispensed on the one hand and a measure of the temperature of the dispensed liquid on the other hand, so that the user can be given information about both the amount of dispensed liquid and its temperature by means of a corresponding double scale. No complicated measuring devices are necessary for this, but an appropriate display can be made solely by the respective position of the actuating element.
Günstig ist es, wenn die Anzeige an der Handspritzpistole oberhalb der Auslaßöffnung angeordnet ist, da die Betätigungsperson in diesem Bereich eine solche Anzeige besonders gut einsehen kann.It is expedient if the display on the hand spray gun is arranged above the outlet opening, since the operator can see such an display particularly well in this area.
Bei einer bevorzugten Ausführungsform ist vorgesehen, daß das Betätigungselement eine die Auslaßöffnung umgebende, um deren Längsachse drehbare Hülse ist.In a preferred embodiment it is provided that the actuating element is a sleeve surrounding the outlet opening and rotatable about its longitudinal axis.
Insbesondere ist es vorteilhaft, wenn die Hülse ein transparentes Fenster trägt, durch welches hindurch ein die Auslaßöffnung aufnehmendes Teil der Handspritzpistole sichtbar ist. Es kann sich dabei beispielsweise um einen Strömungskanal handeln, durch den die Reinigungsflüssigkeit hindurchströmt.In particular, it is advantageous if the sleeve carries a transparent window through which a part of the hand spray gun receiving the outlet opening is visible. It can be, for example, a flow channel through which the cleaning liquid flows.
Es kann bei einer abgewandelten Ausführung auch vorgesehen sein, daß die Handspritzpistole ein transparentes Fenster trägt, durch welches hindurch die Hülse sichtbar ist.In a modified version, it can also be provided that the hand spray gun has a transparent window through which the sleeve is visible.
Dabei ist es vorteilhaft, wenn das Fenster und das durch dieses sichtbare Teil zusammenwirkende Skalen bzw. Markierelemente tragen, die der Bedienungsperson die gewünschte Auskunft über Abgabemenge und Temperatur geben. Besonders vorteilhaft ist es dabei, wenn zwei Skalen vorgesehen sind, nämlich eine Skale für die Abgabemenge und eine Skale für die Temperatur, so daß die Bedienungsperson gleichzeitig diese unterschiedlichen Werte ablesen kann, die in gleicher Weise durch die Stellung des Betätigungselementes beeinflußt werden.It is advantageous if the window and the scales or marking elements interacting through this visible part carry the operator, which provide the operator with the desired information about the dispensing quantity and temperature. It is particularly advantageous if two scales are provided, namely a scale for the quantity dispensed and a scale for the temperature, so that the operator can simultaneously read these different values, which are influenced in the same way by the position of the actuating element.
Bei der bevorzugten Ausführungsform ist vorgesehen, daß in einer quer zu einem Strömungskanal für das Reinigungsmedium in der Handspritzpistole angeordneten Bohrung abgedichtet und längs der Bohrung verschieblich ein Schieber angeordnet ist, der bei unterschiedlicher Stellung in der Bohrung den Strömungskanal verschieden stark einengt und der mittels des Betätigungselementes in der Bohrung verschiebbar ist.In the preferred embodiment it is provided that in a bore arranged transversely to a flow channel for the cleaning medium in the hand-held spray gun and a slide is arranged displaceably along the bore, which narrows the flow channel to different degrees in different positions in the bore and by means of the actuating element is displaceable in the bore.
Wenn das Betätigungselement eine Hülse ist, ist es günstig, wenn sie eine zu ihrer Drehachse exzentrische Gleitbahn trägt, an welcher der Schieber anliegt. Man erhält auf diese Weise eine baulich besonders einfache, nicht auftragende und für die Bedienungsperson trotzdem leicht betätigbare Einstellung für die Drossel in der Handspritzpistole, die gleichzeitig die gewünschte Anzeige der durch die Einstellung erzielten Werte ermöglicht.If the actuating element is a sleeve, it is advantageous if it carries a slideway which is eccentric to its axis of rotation and on which the slide rests. In this way, a structurally particularly simple, non-bulky and nevertheless easily operable setting for the throttle in the hand-held spray gun is obtained, which at the same time enables the desired display of the values achieved by the setting.

Die in der Zeichnung nur teilweise dargestellte Handspritzpistole 1 umfaßt ein Griffteil 2 und ein Gehäuse 3, in dem sich Durchflußarmaturen befinden. In das Griffteil 2 mündet eine Zufuhrleitung für ein Reinigungsmedium in Form eines flexiblen Hochdruckschlauches ein, dieser ist in der Zeichnung nicht dargestellt. Er führt zu einem Strömungskanal 4, der im Inneren des Gehäuses 3 angeordnet ist und sich stufenförmig erweiternd in einer Auslaßöffnung 5 endet, auf die beispielsweise eine in der Zeichnung nicht dargestellte Sprühlanze aufgeschraubt werden kann.The hand-held spray gun 1, which is only partially shown in the drawing, comprises a handle part 2 and a
Auf dem Strömungskanal 4 ist um dessen Längsachse drehbar eine Hülse 6 angeordnet, die außen als Griffhülse ausgebildet ist. Sie trägt auf ihrer Innenseite eine zu ihrer Drehachse exzentrische Gleitbahn 7, an der ein Schieber 8 beidseitig anliegt (Fig. 3), der in einer quer zur Längsrichtung des Strömungskanals 4 diesen durchsetzenden Bohrung 9 abgedichtet und längsverschieblich gelagert ist. In dem Bereich, in dem der Schieber 8 den Strömungskanal 4 durchsetzt, weist dieser ein die Bohrung 9 vollständig ausfüllendes Teil 10 und eine sich daran anschließende Umfangsnut 11 auf, d.h. im Bereich der Umfangsnut 11 ergibt sich zwischen dem Schieber 8 und der Innenwand der Bohrung 9 ein den Schieber 8 umgebender Ringraum 12. Durch Längsverschiebung des Schiebers 8 in der Bohrung 9 läßt sich der Strömungskanal 4 vollständig versperren, wenn nämlich der Teil 10 des Schiebers 8 mit großem Durchmesser in den Strömungskanal 4 eingeschoben wird. Eine vollständige Öffnung des Strömungskanals 4 erhält man jedoch, wenn der Bereich des Ringraumes 12 in den Strömungskanal 4 eingeschoben wird, bei Zwischenstellungen des Schiebers 8 erhält man eine stufenlose Querschnittsverengung des Strömungskanals 4 zwischen diesen beiden Extremwerten. Die Verschiebung des Schiebers 8 erfolgt dabei einfach durch Verdrehung der Hülse 6 und der mit ihr verbundenen exzentrischen Gleitbahn 7.A
Das vordere Ende 13 der Hülse 6 untergreift eine zylindrische Kappe 14, die drehfest auf dem Strömungskanal 4 gelagert ist und an ihrer Oberseite eine rechteckige Ausnehmung 15 aufweist, in der sich ein durchsichtiges Fenster 16 befindet. Durch dieses Fenster 16 hindurch ist der vordere Teil der unterhalb der Kappe 14 angeordneten Hülse 13 zu sehen, die Hülse 13 trägt in diesem Bereich ein schraubenförmig und konzentrisch zur Drehachse der Hülse 13 auf der Außenseite der Hülse aufgezeichnetes Markierelement 17, das durch das Fenster 16 hindurch sichtbar ist und sich bei Verdrehung der Hülse 6 gegenüber dem Strömungskanal 4 im Mittelbereich des Fensters 16 in Längsrichtung des Strömungskanals 4 verschiebt.The
Auf dem Fenster 16 sind zu beiden Seiten der Mitte Skalen 18, 19 aufgezeichnet, zwischen denen ein durchsichtiger Bereich 20 verbleibt, durch den hindurch das Markierelement 17 zu sehen ist. Die beiden Skalen sind gegenläufig angeordnet, eine Skale gibt die Menge der abgegebenen Flüssigkeit an, die andere die Temperatur, beide Größen sind gegenläufig. Damit kann die Bedienungsperson unmittelbar an den beiden Skalen ablesen, wie groß die momentan abgegebene Flüssigkeitsmenge ist und welche Temperatur sie hat. Allein durch Verdrehen der Hülse lassen sich diese Werte in genau zu beobachtender Weise verstellen.
