Abstract

The filter medium (12) is in film or foil form clipped in between a plastics frame and conditioner housing (10). The medium has a hinge (14) held to frame (11) by snap nut and latch (18) as fitted between frame (11) and the plastics conditioner housing (10). The filter medium is held in assembled position by a holddown spring.

Description

Die Erfindung bezieht sich auf eine Vorrichtung nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a device according to the preamble of Claim 1.

Es ist bei Heizungs-/Lüftungsanlagen in Kraftfahrzeugen bekannt, die zugeführte Frischluft vor dem Eintritt in das Heizungs-/Lüftungssystem zu filtern.It is known in heating / ventilation systems in motor vehicles, the supplied Filter fresh air before entering the heating / ventilation system.

Ebenso ist es bekannt, eine Luftfilterung bei Stellung der Heizungs-/Lüftungsanlage auf Umluftbetrieb vorzunehmen. Probleme entstehen hier nach langer Betriebsdauer durch Verstopfung der Filteranlage.It is also known to air filter when the heating / ventilation system is on Air recirculation. Problems arise here after a long period of operation Blockage of the filter system.

Aufgabe der Erfindung ist es, eine dem Frischluftbetrieb entsprechende Qualität der Luftfilterung auch im Umluftbetrieb über eine nahezu unbegrenzte Zeitdauer zu gewährleisten.The object of the invention is to provide a quality corresponding to the fresh air operation Air filtering also in recirculation mode over an almost unlimited period of time guarantee.

Erfindungsgemäß wird die Aufgabe bei einer Vorrichtung der eingangs bezeichneten Art durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst.According to the invention, the object is achieved in a device of the type described at the outset solved by the characterizing features of claim 1.

Durch die Auswechselbarkeit des Filtermediums entfällt das bisherige Problem der Verstopfung, da ein verstopftes Filtermedium jederzeit durch ein neues ersetzt werden kann. Ein weiterer Vorteil der Auswechselbarkeit des Filtermediums liegt darin, daß sich Fahrzeuge, die bisher nur über eine Frischluftfilterung verfügen, jederzeit mit einer Umluftfilteranlage nachrüsten lassen.The interchangeability of the filter medium eliminates the previous problem of Blockage because a blocked filter medium can be replaced with a new one at any time can. Another advantage of the interchangeability of the filter medium is that Vehicles that so far only have fresh air filtering with one at any time Have the air filter system retrofitted.

Vorteilhafte Ausgestaltungen des Grundgedankens der Erfindung sind den Patentansprüchen 2-5 zu entnehmen.Advantageous embodiments of the basic idea of the invention are Claims 2-5.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt, das im folgenden näher erläutert wird. Es zeigt (jeweils schematisch und ausschnittsweise):In the drawing, an embodiment of the invention is shown, the following is explained in more detail. It shows (each schematically and in sections):

Fig. 1 eine mit einem Klimagerät ausgerüstete Heizungs-/Lüftungsanlage für Kraftfahrzeuge, in Draufsicht (Ansicht "X" in Fig. 2), und Fig. 1 is equipped with an air conditioner heating / ventilation system for motor vehicles, in plan view (view "X" in Fig. 2), and

Fig. 2 einen Schnitt längs der Linie II-II in Fig. 1. FIG. 2 shows a section along the line II-II in FIG. 1.

Es bezeichnet 10 einen Gehäuseteil des (im übrigen nicht gezeigten) Klimagerätes und 11 einen Kunststoffrahmen der Heizungs-/Lüftungsanlage. Zwischen dem Gehäuseteil 10 und dem Kunststoffrahmen 11 ist ein insgesamt mit 12 beziffertes Filtermedium angeordnet, welches folienförmig ausgebildet ist und eine Dicke von ca. 0,5 mm aufweist. Das folienförmige Filtermedium 12 ist mittels einer Schnappmutter 13 und einer Verrastung 18 an dem Kunststoffrahmen 11 lösbar gehalten. Ein Filmscharnier 14 ermöglicht die Ausrichtung des Filtermediums 12 in die aus Fig. 2 ersichtliche Montagestellung bzw. eine Schwenkbarkeit des Filtermediums aus dieser Montagestellung heraus. Mit 15 ist die Schwenkachse einer Umluftklappe 16 beziffert. Die Entfernungsrichtung des Filtermediums 12 markiert ein Pfeil 17.It designates 10 a housing part of the air conditioning unit (not shown in the rest) and 11 a plastic frame of the heating / ventilation system. Between the housing part 10 and the plastic frame 11 there is a filter medium, numbered 12 overall, which is film-shaped and has a thickness of approximately 0.5 mm. The film-shaped filter medium 12 is releasably held on the plastic frame 11 by means of a snap nut 13 and a catch 18 . A film hinge 14 enables the alignment of the filter medium 12 in the mounting position shown in FIG. 2 or a pivoting of the filter medium out of this mounting position. The pivot axis of a recirculation flap 16 is numbered 15 . The direction of removal of the filter medium 12 is marked by an arrow 17 .
