Abstract

The filter includes a flexible and permeable support (a) contg. or a adjacent to chemical sorption agents (b). The support (a) is pref. a fabric or cloth, either of which may be quilted, and esp. contg. waterproof materials, e.g. fibres or similar elements made of ceramics, glass, plastics or metals, and quilted like a mattress to form layers between which agents (b) are located. Different agents (b) may be used in the various layers. Agents (b) are pref. active carbon; and/or active coke; and/or CaCl2; and/or soda lime; and/or a catalyst for CO. The agents may be fixed in or on support (a) as a liq., e.g. NaOH soln.; or as powders; or on expanded granules of Ca-Al-silicate. The catalyst for CO is pref. 60% MnO2, 40% CuO; or 50% MnO2, 30% CuO, 15% cobalt oxide and 5% Ag2O. Air breathed by the driver and passengers is purified from noxious substances even in very dense traffic, etc.

Patent- und Hilfsgebrauchsmusteranmeldung "Zweistrom-Belüftung für Autokabinen Autokabinen werden über Belüftungsschlitze am Ende der Kühlerhaube oder in der Kühlerhaube, die mit Leitkanälen in Verbindung stehen, belüftet.Patent and utility model registration "Two-flow ventilation for Car cabins Car cabins are opened via ventilation slots at the end of the hood or hood in the radiator hood, which are connected to the ducts.

Es ist bekannt, Filter in die Belüftungskanäle einzubauen.It is known to install filters in the ventilation ducts.

Diese Filter sollen Schadstoffe für die Insassen der Autokabinen fernhalten.These filters are designed to keep pollutants away for the occupants of the car cabins.

Alle Filter zur Chemisorption von Schadstoffen bewirken natürlich einen Widerstand, der nur über den Belüftungsventilator überwunden werden kann.All filters for chemisorption of pollutants work naturally a resistance that can only be overcome using the ventilation fan.

Bei Langsamfahrten stört das Filtergeräusch.The filter noise is annoying when driving slowly.

Bei Fahrten durch waldreiche Gegenden oder nicht befahrene Straßen könnte der Autofilter abgeschaltet sein, und trotzdem sollte und muß Luft zur Belüftung der Insassen in die Kabinen eingelassen werden.When driving through wooded areas or roads that are not used the autofilter could be switched off, but air should and must still be used for ventilation of the occupants are allowed into the cabins.

Aus diesem Grunde wird erfindungsgemäß vorgeschlagen, wie bereits vielfach angewendet, eine Zweistrom-Belüftung für Autokabinen zu verwenden, wobei ein Ansaugschlitzkanal mit einem Chemisorptionsfilter ausgerüstet ist, der nach Bedarf, d.h. bei stark befahrenen Straßen, eingeschaltet wird und die gesamte Luft zur Belüftung der Autokabine durch den Chemisorptionsfilter fließen muß.For this reason it is proposed according to the invention, as already often used to use a two-stream ventilation for car cabins, with an intake slot channel is equipped with a chemisorption filter, which after As required, i.e. on busy roads, is switched on and all of the air must flow through the chemisorption filter to ventilate the car cabin.

Bei Fahrten durch Gebiete mit Straßen, die kaum oder schwach befahren sind, kann der Chemisorptionsfilter abgeschaltet werden und die Luft durch den anderen Kanal ungestört in die Autokabine ohne Zuhilfenahme von einem Lüfter einfließen.When driving through areas with roads with little or no traffic the chemisorption filter can be switched off and the air through the other The duct can flow into the car cabin undisturbed without the aid of a fan.

Tp der beiliegenden Zeichnung ist die Erfindung dargestellt: mit 1 der Chemisorptionsfilter in einem der Ansaugkanäle, mit 2 der Ansaugkanal ohne Chemisorptionsfilter, mit 3 der Belüftungskanal zur Kabinenbelüftung, mit 4 eine Vorrichtung beliebiger Ausführung, z. B. mit Klappenmechanismus, die nach Bedarf nach links oder rechts den entsprechenden gewünschten Knal abschließt oder öffnet.Tp of the accompanying drawing shows the invention: with 1 the chemisorption filter in one of the intake ducts, with 2 the intake duct without chemisorption filter, with 3 the ventilation duct for cabin ventilation, with 4 any device Execution, e.g. B. with a flap mechanism that can be turned to the left or right as required closes or opens the corresponding desired bang.

Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen beschriebenen und gezeichneten Ausbildungsformen beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzulassen, für die Belüftunq von Autokabinen eine Zweistrom-Belüftung zu wählen oder auch Mehrstrom-Belüftung, wobei bedarfsgerecht die Belüftung zur Kabine über einen Kanal oder mehrere Kanäle geleitet wird, in dem Chemisorptionsfilter eingebaut sind und wahlweise gewechselt werden kann, indem der Chemisorptionsfilterteil mit dem entsprechenden Kanal abgeschaltet wird und die Luft ungefiltertbzw. nur durch einen Staubfilter, jedoch nicht gleich einem Chemisorptionsfilter, in das Wageninnere eingeleitet werden kann.Of course, the invention is not limited to the above in detail The forms of training described and drawn are limited, but there are numerous Modifications are possible, but without abandoning the basic idea, for the ventilation to choose dual-flow ventilation or multi-flow ventilation for car cabins, ventilation to the cabin via one or more channels as required is conducted, in which chemisorption filters are installed and optionally changed can be switched off by the chemisorption filter part with the corresponding channel and the air is unfiltered or only through a dust filter, but not immediately a chemisorption filter that can be introduced into the interior of the car.

Claims (1)

Anspruch 1 Belüftung für Autokabinen dadurch gekennzeichnet, daß sie vorzugsweise durch Mehrstromkanäle in den Hauptbelüftungsteil zur Kabinenbelüftung eingeführt wird, wobei bedarfsgerecht die Luft einmal direkt zwangsweise über einen oder mehrere Ansaugkanäle, die mit Chemisorptionsfiltern ausgerüstet sind, geleitet wird zur Abscheidung der Schadstoffe für den Menschen oder wunschgerecht die Luft ohne Durchfahrung durch einen Chemisorptionsfilter, z. B. auch ohne jeglichen Staubfilter, zur Kabinenbelüftung nur durch den Fahrwind eingedrückt wird oder unter Zuhilfenahme eines Ventilators leicht regelbar einfließen kann.Claim 1 ventilation for car cabins, characterized in that they preferably through multi-flow channels in the main ventilation section for cabin ventilation is introduced, with the air forced once directly through one as required or several intake ducts equipped with chemisorption filters is used to separate the pollutants for humans or the air as desired without passing through a chemisorption filter, e.g. B. even without any dust filter, for cabin ventilation is only pressed in by the wind or with the help of it of a fan can be easily regulated.
