Abstract
Description
Die Erfindung betrifft eine Heizvorrichtung zum Erwärmen einer Fensterscheibe eines Kraftfahrzeugs sowie ein entsprechendes Verfahren.The The invention relates to a heating device for heating a window pane of a Motor vehicle and a corresponding method.
Autofahrer haben, besonders im Winter, oft mit dem Problem zu kämpfen, dass bei einem im Freien abgestellten Kraftfahrzeug die Fensterscheiben beschlagen oder gar vereist sind. Dadurch wird die Sicht versperrt, und die Scheiben müssen erst frei gemacht werden, bevor man losfahren kann. Eine für den Fahrer bequeme Möglichkeit, die Scheiben von Eis etc. zu befreien, besteht darin, diese zu erwärmen. Dies kann mittels eines Lüfters des Kraftfahrzeugs geschehen. Der Lüfter bläst beheizte Drähte an und leitet die aufgeheizte Luft über Kanäle weiter. Die warme Luft wird dann auf die Fensterscheiben des Kraftfahrzeugs gerichtet. Dabei ergibt sich aber eine große Verlustleistung. Außerdem ist dieses Verfahren relativ laut, und kalte und „schlechte” Luft wird permanent umgewälzt.motorist especially in the winter, often struggle with the problem that in a parked vehicle outdoors the windows misted or even iced. This obstructs the view, and the discs have to only be released before you can go. One for the driver convenient way to free the slices of ice etc. is to heat them. This can by means of a fan of the motor vehicle. The fan blows on heated wires and passes the heated air over channels further. The warm air is then applied to the windows of the motor vehicle directed. But this results in a large power loss. Besides that is This process is relatively loud, and cold and "bad" air is constantly circulated.
Eine andere bekannte Methode, die Scheiben zu befreien oder frei zu halten, ist, die Scheiben direkt durch in der Scheibe angeordnete Heizdrähte zu erwärmen. Dies geht jedoch mit einem sehr großen Stromverbrauch einher. Außerdem sind Heizdrähte nicht in jede Scheibe ohne weiteres integrierbar und bedeuten auch einen großen Kostenfaktor in der Scheibenherstellung.A another known method of freeing or keeping the discs free, is to heat the discs directly through arranged in the disc heating wires. This but goes with a very big one Electricity consumption. Furthermore are heating wires not easily integrable into any disc and also mean a big Cost factor in the disc production.
Aufgabe der vorliegenden Erfindung ist es daher, eine Heizvorrichtung und ein Verfahren zum Erwärmen einer Fensterscheibe eines Kraftfahrzeugs der eingangs genannten Art zu schaffen, welche ein effektives Erwärmen der Fensterscheibe ermöglichen.task The present invention is therefore a heater and a method of heating a window pane of a motor vehicle of the aforementioned To create kind, which allow an effective heating of the window pane.
Diese Aufgabe wird erfindungsgemäß durch eine Heizvorrichtung mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen Weiterbildungen der Erfindung sind in den abhängigen Patentansprüchen angegeben.These The object is achieved by a Heater solved with the features of claim 1. advantageous Embodiments with expedient developments of the invention are in the dependent claims specified.
Gemäß einem weiteren Aspekt der Erfindung wird diese Aufgabe durch ein Verfahren gemäß dem Patentanspruch 11 gelöst.According to one Another aspect of the invention, this object is achieved by a method according to the claim 11 solved.
Der Erfindung liegt die Erkenntnis zugrunde, dass Energieverluste vermieden werden können, wenn elektrische Energie mittels Wellenstrahlung ohne Trägermedium an die zu erwärmende Fensterscheibe abgegeben wird. Deshalb ist bei der erfindungsgemäßen Heizvorrichtung zumindest ein Wärmestrahler vorgesehen, mittels welchem zumindest ein Teilbereich der Fensterscheibe zu bestrahlen ist. Dadurch wirkt die Energie sofort an der aufzuheizenden Scheibe, ohne dass zuvor ein Trägermedium erwärmt werden muss. So kann die Fensterscheibe schnell und fast ohne Verlustleistung erwärmt werden. Dieser Vorgang ist außerdem lautlos.Of the The invention is based on the finding that energy losses avoided can be, if electrical energy by means of wave radiation without carrier medium to be heated Window is discharged. Therefore, in the heater according to the invention at least one heat radiator provided by means of which at least a portion of the window pane to be irradiated. As a result, the energy acts immediately on the aufzuheizenden Slice without having previously been a carrier medium heated must become. Thus, the window pane can be fast and almost without power loss heated become. This process is also silently.
Gemäß einer bevorzugten Ausgestaltung der Erfindung ist der zumindest eine Wärmestrahler an der Rückseite eines Innenspiegels des Kraftfahrzeugs angeordnet. In diesem Fall dient der Wärmestrahler zur Erwärmung einer Windschutzscheibe des Kraftfahrzeugs. Die Rückseite des Innenspiegels befindet sich nahe an der Windschutzscheibe, was vorteilhaft ist, da umso weniger Energie zum Aufheizen notwendig ist, je näher der Wärmestrahler sich an der zu bestrahlenden Scheibe befindet. Zudem ist eine direkte Bestrahlung der Scheibe gewährleistet. Ein weiterer Vorteil der Anordnung am Innenspiegel besteht darin, dass der Wärmestrahler so modular- oder konzeptgleich integrierbar und in allen Baureihen, sogar in anderen Segmenten, wie beispielsweise Lastkraftwagen, einsetzbar ist. Außerdem ist die Lage des Wärmestrahlers über ein Einstellen des Innenspiegels veränderbar.According to one preferred embodiment of the invention, the at least one heat radiator the back an interior mirror of the motor vehicle. In this case serves the heat radiator for warming a windshield of the motor vehicle. The backside The interior mirror is close to the windshield, which is advantageous is because the less energy is needed to heat up, the closer the Radiant heaters is located on the disk to be irradiated. In addition, a direct Irradiation of the disc guaranteed. One Another advantage of the arrangement on the rearview mirror is that the heat radiator as modular or concept integrated and in all series, even in other segments, such as trucks, can be used is. Furthermore is the location of the heat radiator over a Adjusting the interior mirror changeable.
Gemäß einer weiteren bevorzugten Ausgestaltung der Erfindung ist der zumindest eine Wärmestrahler in eine Himmelverkleidung des Kraftfahrzeugs eingebaut. In diesem Fall können neben der Windschutzscheibe auch die Heckscheibe oder die Seitenscheiben erwärmt werden. Ebenso kann eine Scheibe eines Dachfensters erwärmt werden. Der Wärmestrahler ist dazu in einem an die zu bestrahlende Fensterscheibe angrenzenden Bereich der Himmelverkleidung, insbesondere nah am Dachrahmen, anzuordnen. Dadurch wird ebenfalls eine direkte Bestrahlung der Scheibe erreicht. Vorzugsweise ist der zumindest eine Wärmestrahler entlang einer Teilstrecke der Oberkante der zu bestrahlenden Fensterscheibe in der Himmelverkleidung angeordnet. Bei dieser Anordnung befindet sich der Wärmestrahler sehr nah an der Scheibe. Auch ein in die Himmelverkleidung eingebauter Wärmestrahler ist modular- oder konzeptgleich integrierbar. Außerdem ist hier die Lage des Wärmestrahlers relativ zur Fensterscheibe unveränderbar.According to one Another preferred embodiment of the invention is at least a heat radiator installed in a sky panel of the motor vehicle. In this Case can in addition to the windshield and the rear window or side windows heated become. Likewise, a pane of a roof window can be heated. The heat radiator is in an adjacent to the window pane to be irradiated Area of the sky fairing, in particular close to the roof frame to arrange. As a result, a direct irradiation of the disc is also achieved. Preferably, the at least one heat radiator is along a partial path the top edge of the window pane to be irradiated in the sky panel arranged. In this arrangement, there is the heat radiator very close to the disc. Also a built in the sky fairing Radiant heaters is modular or concept integrated. Also, here is the location of the heat radiator invariable relative to the window pane.
Die im Zusammenhang mit der erfindungsgemäßen Vorrichtung beschriebenen bevorzugten Ausführungsformen und Vorteile gelten, soweit anwendbar, auch für das erfindungsgemäße Verfahren zum Erwärmen einer Fensterscheibe eines Kraftfahrzeugs.The described in connection with the device according to the invention preferred embodiments and advantages apply, as far as applicable, also for the inventive method for Heat a window pane of a motor vehicle.
