Abstract

The anti-misting device uses a sensor for detecting deposition of moisture on a windscreen or mirror surface, in combination with a control module, used for on-off switching of a heating device for heating the windscreen or mirror surface.

Description

Die Erfindung entspricht einer Vorrichtung entsprechend dem Oberbegriff des Anspruch 1.The invention corresponds to a device according to the preamble of Claim 1.

Scheiben oder Wände beschlagen aus verschiedenen Ursachen und müssen dann von Hand gereinigt werden. An einigen Flächen gibt es spezielle Heizungen dafür, diese müssen aber von Hand ein- bzw. ausgeschalten werden.Windows or windows mist up for various reasons and then have to be cleaned by hand. There are special heaters on some surfaces for this, but these must be switched on or off manually.

Durch das manuelle ein- bzw. ausschalten dieser Heizungen ist die Scheibe oder Wand nicht immer ideal vom Wasser, daß den Beschlag verursacht, befreit. Auch verschwendet man Energie wenn die Heizung nicht rechtzeitig wieder ausgeschaltet wird. Es kann z. B. beim Auto sogar so weit kommen, das die Batterie völlig entleert wird.By manually switching these heaters on or off, the disc is or Wall not always ideally freed from water that causes fogging. Also one wastes energy if the heating is not on time again is turned off. It can e.g. B. in the car even come so far that the Battery is completely drained.

Aufgabe der Erfindung ist es, solche beschlagenen Oberflächen zu erkennen und die nötigen Schritte dagegen einzuleiten. Weiterhin ist es seine Aufgabe, wenn die Oberfläche wieder trocken ist, sich wieder aus zu schalten. Diese Vorgänge sind voll automatisch.The object of the invention is to recognize such fogged surfaces and take the necessary steps against it. It is also his job if the surface is dry again, turn off again. These processes are fully automatic.

Diese Aufgabe wird durch eine Vorrichtung mit dem Merkmalen des Anspruch 1 gelöst.This object is achieved by a device with the features of claim 1 solved.

Ein Sensor wird auf der Oberfläche angebracht. Dieser beobachtet ständig ob die Oberfläche sich gerade beschlägt.A sensor is attached to the surface. This constantly monitors whether Surface is fogging up.

Durch ein ständiges Messen des Sensors ist dem Baustein ein Ausschalten ebenfalls möglich.The module can be switched off by constantly measuring the sensor also possible.

Der Baustein kann ein Beschlagen schon im Erststadium erkennen und somit auch vorbeugend wirken. The block can detect fogging in the first stage and thus also work preventively.  

Der Sensor müßte die Eigenschaft besitzen, die Oberfläche zu scannen um festzustellen, in welchen Zustand diese momentan ist. Dafür gibt es viele Möglichkeiten: die wahrscheinlich beste Möglichkeit ist, wenn zwei leitende Streifen auf die Scheibe oder Wand geklebt würden. Der elektronische Baustein könnte dann mit diesem Sensor mit einer Darlington-Transistor-Schaltung in Kopplung eines Relais gelöst werden. Wenn z. B. Kondenswasser auf die Oberfläche kommt, dann ändert sich der Widerstand am Sensor und das Relais schaltet. Dieser Sensor erkennt nicht nur ein beschlagen der Oberfläche, sondern auch ein vereisen dieser. Den größten nutzen hat der Sensor am Auto, an der Heckscheibe: der Autofahrer braucht sich nicht mehr um den Zustand dieser beim Fahren zu kümmern, da die Schaltung mit dem Sensor ein Beschlagen unmöglich macht. Man kann ihn aber auch am Außenspiegel anbringen. Wenn sich eine Heizung hinter den Spiegeln befindet, kann er gegebenenfalls diese automatisch einschalten und den Spiegel enteisen. An Spiegeln, die sich beschlagen, kann der Sensor ebenfalls angebracht werden. Eine Heizung hinter dem Spiegel kann dann automatisch vom Baustein eingeschalten werden. Es gibt viele Möglichkeiten diese Erfindung anzuwenden.The sensor should have the property of scanning the surface in order to determine what state it is in at the moment. There are many for that Possibilities: Probably the best option is when two are senior Strips would be glued to the pane or wall. The electronic component could then use this sensor with a Darlington transistor circuit in Coupling a relay can be solved. If e.g. B. condensation on the Surface comes, then the resistance at the sensor and the relay changes switches. This sensor not only detects fogging of the surface, but also also an ice this. The sensor on the car has the greatest benefit Rear window: the driver no longer needs to worry about the condition of this when Driving to worry because the circuit with the sensor fogging up impossible makes. But you can also attach it to the outside mirror. If there is one Heating is located behind the mirrors, he can do this automatically if necessary switch on and defrost the mirror. He can use mirrors that fog up Sensor can also be attached. A heater behind the mirror can then are automatically switched on by the block. There are many opportunities to apply this invention.
