Heiz- und/oder KlimagerätHeating and / or air conditioning device

Die Erfindung bezieht sich auf ein Hsiz- und/oder Klimagerät, insbesondere für Kraftfahrzeuge, das einen Luftmengenschalter aufweist, der mindestens ein hilfskraftbetriebenes Stellorgan zur Betätigung v/enigstens einer Frischluftklappe und ein mehrstufiges Gebläse nacheinander steuert. Bei einem bekannten derartigen Gerät (DT-OS 24 03 316) ist der Frischlufteintritt mittels eines einstufigen Stellorganes lediglich zwischen AUF und ZU verstellbar. Dadurch ist es nicht möglich, die Frischluftzufuhr im Bereich des Stauluftbetriebes zu dosieren, was zu unangenehmen Zug- oder Frischluftmangel-Erscheinungen führt.The invention relates to a heating and / or air conditioning unit, in particular for motor vehicles, which has an air volume switch that has at least one servo-operated actuator to operate at least one fresh air flap and a multi-stage fan controls one after the other. With a well-known Such a device (DT-OS 24 03 316) is the fresh air inlet by means of a single-stage actuator only between OPEN and CLOSED adjustable. As a result, it is not possible to supply fresh air to dose in the area of ram air operation, which leads to unpleasant drafts or lack of fresh air leads.

Der Erfindung liegt die Aufgabe zugrunde, ein Gerät der beschriebenen Bauart so weiterzubilden, daß mit einfachen Mitteln ein Dosieren der Frischluft über den gesamten Betriebsbereich erzielbar ist. The invention has for its object to provide a device of the described To further develop the design so that the fresh air can be metered over the entire operating range with simple means.

Diese Aufgabe löst die Erfindung dadurch, daß 'die Frischluftklappe bzw.-klappen mittels v/enigstens eines Stellorganes mehrstufig und die Stufen der Frischluftklappe bzw.-klappen und des Gebläses nacheinander steuerbar sind. Durch die AuslegungThe invention solves this problem in that 'the fresh air flap or flaps by means of at least one actuator in multiple stages and the stages of the fresh air flap or flaps and of the fan can be controlled one after the other. By the interpretation

des "bzw. der Stellorgane für ein stufenweises Verstellen der Frischluftklappe und ggf. gemäß Anspruch 2 an das Öffnen der ersten Frischluftklappe anschließendes Öffnen der zweiten Frischluftklappe wird ein mehrstufiges Dosieren der Frischluftmenge ermöglicht. Durch die Merkmale des Anspruches 3 ergibt sich eine dreistufige, den Erfordernissen eng angepaßte Luftmengensteuerung mit einfachen Bauelementen.des "or the actuators for a gradual adjustment of the Fresh air flap and, if necessary, according to claim 2, after opening the first fresh air flap, opening the second one Fresh air flap is a multi-stage metering of the fresh air volume enables. Due to the features of claim 3 results a three-stage, closely adapted air volume control with simple components.

Es ist zwar bekannt, mechanische Übertragungseinrichtungen, wie z.B. Bowdenzüge zur stufenlosen Betätigung von Frisch- « luftklappen zu verwenden, jedoch sind diese häufig schwergängig und deren Hebel und Knöpfe erfordern einen großen Raum am Bediengerät. cAlthough it is known that mechanical transmission devices, such as Bowden cables for stepless actuation of fresh « To use air flaps, however, these are often stiff and their levers and buttons require a large space on the control unit. c

Im folgenden wird die Erfindung anhand von Ausführungsbeispielen unter Bezugnahme auf die Zeichnung näher erläutert. 3s zeigt:In the following the invention is illustrated by means of embodiments explained in more detail with reference to the drawing. 3s shows:

In Fig. 2 werden vom Luft-nengenschaiter 12 Stellorgane 14 und 15 für zwei Frischluftklappen Io und 17 sowie ein Gebläse 13 gesteuert. Aus dem in Fig. 3 dargestellten zugehörigen Funktionsablaufplan ist zu erkennen, daß in der Stellung 11O" des Luftmengenschalters 12 alle Frischluftklappen 16 und 17 geschlossen sind und das Gebläse 18 abgeschaltet ist. In der Stellung "1" des Luftmengenschalters 12 ist die Frischluftklappe 16 halb und in der Stellung "2" ganz geöffnet. In der Stellung "3" ist zusätzlich die Frischluftklappe 17 geöffnet und'die erste Stufe des Gebläses 13 eingeschaltet. In den Stellungen "4", "5" und "6" des Luf^cmengenschalters 12 sind weiterhin beide Frischluftklappen 16 und 17 geöffnet und die zweite, dritte bzw. vierte Stufe des Gebläses 18 eingeschaltet.In FIG. 2, actuators 14 and 15 for two fresh air flaps Io and 17 as well as a fan 13 are controlled by the air nenengenschaiter 12. From the associated functional flow chart shown in FIG. 3 it can be seen that in the position 11 O "of the air quantity switch 12 all fresh air flaps 16 and 17 are closed and the fan 18 is switched off. In the position" 1 "of the air quantity switch 12, the fresh air flap 16 is half open and fully open in position "2". In position "3", the fresh air flap 17 is also open and the first stage of fan 13 is switched on. In positions "4", "5" and "6" of the air Quantity switch 12, both fresh air flaps 16 and 17 are still open and the second, third and fourth stages of the fan 18 are switched on.

Bei dem Ausführungsbeispiel nach Fig. 4 v/erden vorn Luftmengenschalter 12 ein Stellorgan 19 für eine Frischluftklappe 20 und das Gebläse 18 gesteuert, wie aus dem in Fig. 5 dargestellten Funktionsablaufplan zu erkennen ist. In den Stellungen "O" und "1" des Luftmengenschalters 12 ist die Frischluftklappe ein Drittel geöffnet und das Gebläse 18 abgeschaltet. In der Stellung "2" ist bei weiterhin abgeschaltetem Gebläse 18 die Frischluftklappe 20 zwei Drittel geöffnet und in der Stellung "3" ist die Frischluftklappe 20 ganz geöffnet und die erste Stufe des Gebläses 18 eingeschaltet. In den weiteren Stellungen "4", "5" und "6" des Luftmengenschalters 12 sind die entsprechenden weiteren Stufen des Gebläses 18 eingeschaltet und die Frischluftklappe 20 ist weiterhin vollständig geöffnet. Statt einer Schließstellung der Frischluftklappe 20 können in Stellung "0" des Luftmengenschalters 12 durch diesen die vom Luftverteilerschalter 13 gesteuerten - nicht dargestellten - Klappen gemeinsam geschlossen v/erden.In the exemplary embodiment according to FIG. 4, the air volume switch is grounded at the front 12, an actuator 19 for a fresh air flap 20 and the blower 18 are controlled, as shown in FIG. 5 Functional flow chart can be seen. The fresh air flap is in the "O" and "1" positions of the air volume switch 12 a third opened and the fan 18 switched off. In the "2" position, the fan 18 is still switched off Fresh air flap 20 is open two thirds and in position "3" the fresh air flap 20 is fully open and the first Level of the fan 18 switched on. In the other positions "4", "5" and "6" of the air volume switch 12 are the corresponding further stages of the fan 18 switched on and the fresh air flap 20 is still fully open. Instead of a closed position of the fresh air flap 20 can in position "0" of the air volume switch 12 by this from the air distribution switch 13 controlled - not shown - flaps together closed v / ground.

Durch diese Ausbildung wird mit relativ einfachen Mitteln eine gute Dosierung der durch die Heiz-· oder Klimaanlage strömenden Luftmenge erreicht.This design enables good metering of the amount flowing through the heating or air conditioning system with relatively simple means Air volume reached.
