Description

Anwendungsgebietfield of use

Die Erfindung betrifft eine Vorrichtung gemäß dem Oberbegriff des Anspruchs 1. Sie ermöglicht die Steuerung von Schutzeinrichtungen für wasserempfindliche Objekte, wie beispielsweise Wohndachfenster welche bei Regen geschlossen sein müssen, da sonst das Wasser die Wohneinrichtung beschädigen würde.The The invention relates to a device according to the preamble of the claim 1. It allows the control of protective devices for water-sensitive objects, such as roof windows which closed when it rains have to be otherwise the water would damage the home furnishings.

Stand der TechnikState of technology

Es gibt Regensensoren die auf Messung des elektrischen Widerstandes zwischen zwei der Benetzung durch den Regen ausgesetzte Elektroden basieren. Die Elektroden weisen die verschiedensten Formen auf, aber immer bildet das Wasser zwischen den zwei Elektroden eine leitfähige Verbindung, so dass der Regen durch das Absinken des Widerstandes erkannt werden kann.It Rain sensors are the measurement of electrical resistance between two electrodes exposed to wetting by the rain based. The electrodes have a great variety of shapes, but always the water forms a conductive connection between the two electrodes, so that the rain is detected by the decrease in resistance can.

Nachteile des Standes der Technikdisadvantage of the prior art

Mängel der heute verfügbaren Regensensoren, die auf Widerstandsmessungen basieren bestehen hauptsächlich in ihrer komplizierten Bauweise und der unvorteilhaften Materialanwendung. Dies verursacht einen hohen Verkaufspreis und eine ständige Pflege und Wartung des Regensensors. Es kann z. B. durch unvorteilhaften Materialeinsatz zur Oxydation zwischen den zwei Elektroden kommen. Die üblichen automatischen Fensterschließanlagen sind im Verhältnis – Aufwand und Nutzen – sehr teuer und können ein vielfaches des Dachfensterpreises betragen.Shortcomings of available today Rain sensors based on resistance measurements are mainly made in their complicated construction and the unfavorable use of materials. This causes a high selling price and a constant care and maintenance of the rain sensor. It can, for. B. by unfavorable Material used for oxidation between the two electrodes. The usual automatic window closing systems are in proportion - effort and benefits - very much expensive and can be a multiple of the roof window price.

In Deutschland wird hauptsächlich der Regensensor „Rotomatic RSP" eingesetzt.In Germany becomes mainly the rain sensor "Rotomatic RSP "used.

Aufgabe der ErfindungObject of the invention

Die Erfindung verfolgt das Ziel, einen Regensensor nach dem Prinzip der Widerstandsmessung zu realisieren der die genannten Nachteile nicht aufweist und sich selbständig reinigt.The Invention pursues the aim of a rain sensor according to the principle the resistance measurement to realize the mentioned disadvantages does not have and self-employed cleans.

Lösungsolution

Die Aufgabe der Erfindung wird durch eine Bauweise mit den Merkmalen des Anspruchs 1 gelöst. Es wird eine mit 90° abgewinkelten, nicht elektrisch leitenden, Kunststoffschiene als Regentropfensammler verwendet.The The object of the invention is achieved by a construction with the features of claim 1. It will be a 90 ° angled, non-electrically conductive plastic rail as raindrop collector uses.

In dieser sind im unteren Drittel drei kleine vergoldete Elektroden eingearbeitet. Die Kunststoffschiene ist an einem Fuß drehbar verbunden. Durch die vertikale Verstellmöglichkeit kann man den größtmöglichsten Wassereintritt erreichen.In These are three small gold-plated electrodes in the lower third incorporated. The plastic rail is rotatable on one foot connected. The vertical adjustment allows you to the largest possible Reach water inlet.

Es wird eine Ansprechschwelle positiv beeinflusst.It a threshold is positively influenced.

Durch einen elektrischen Schalter können die Abstände zwischen den Elektroden verändert werden, wodurch außerdem die Ansprechschwelle regelbar ist. Die drei sehr kleinen vergoldeten Elektroden sind den Wettereinflüssen gegenüber unempfindlich, preiswert und erfüllen sehr gut ihren Zweck. Die einfache und günstige Materialauswahl und Bauweise ermöglicht eine kostengünstige und brauchbare Herstellung des neuen Regensensors.By an electric switch can the distances be changed between the electrodes, as well the threshold is adjustable. The three very small gilded Electrodes are the weather influences across from Insensitive, inexpensive and fulfilling very well its purpose. The simple and cheap material selection and Construction allows a cost-effective and useful production of the new rain sensor.

Ein Ausführungsbeispiel des Regensensors ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Es zeigen:One embodiment the rain sensor is shown in the drawing and will be described in more detail below. Show it:

1 – eine schräge Ansicht auf den Regensensor
Mit Hilfe einer Rinne wird das Regenwasser aufgefangen und durch diese Form zielgerichtet über drei elektrisch vergoldete Fühlerkontakte-Elektroden (6), geleitet. Diese Rinne, im weiteren Regentropfensammler genannt, besteht aus einem 90° abgewinkelten zweischenkligen Teil aus nicht elektrisch leitenden, wasserabweisenden Material. Das Regenwasser bildet beim Überfließen der Fühlerkontakte (6) vorübergehend elektrisch leitende Wasserbrücken zwischen den Kontakten. Dadurch verringert sich der Widerstand zwischen den Fühlerkontakten-Elektroden (6), welcher in einer elektronischen Schalteinheit gemessen wird. Der Messwert dient zur Steuerung der Fensterschließeinrichtung. Durch eine Umschaltmöglichkeit können die Entfernung zwischen zwei Fühlerkontakten (6) verändert werden, was den Vorteil hat, dass beeinflusst werden kann, ob bei stärkerem oder schwächerem Regenfall das Dachfenster geschlossen werden soll. Der Regensammler (1) ist an der unteren Stoßkante mit einer halbrunden, schmalen Sockelleiste (2) fest verbunden. Über eine lösbare Verbindung, Abflusswinkeleinsteller (3) kann man den Ablauf und das Auffangen des Regenwassers beeinflussen. Diese Vorrichtung dienst außerdem zur besseren Selbstreinigung und zum Einjustieren des Regentropfensammlers (1). Die o. g. Teile sind über den Winkeleinsteller (3) mit einem Ständer (5) und einem Fuß (4) in vertikaler Richtung, beweglich verbunden.
1 - an oblique view of the rain sensor
With the help of a gutter, the rainwater is collected and targeted by this form via three electrically gold-plated probe contact electrodes ( 6 ). This channel, hereinafter called the raindrop collector, consists of a 90 ° angled two-legged part of non-electrically conductive, water-repellent material. The rainwater forms when overflowing the sensor contacts ( 6 ) temporarily electrically conductive water bridges between the contacts. This reduces the resistance between the sensor contact electrodes ( 6 ), which is measured in an electronic switching unit. The measured value serves to control the window closing device. By switching over the distance between two sensor contacts ( 6 ), which has the advantage that it can be influenced whether the roof window should be closed in case of stronger or weaker rainfall. The rain collector ( 1 ) is at the lower edge with a semicircular, narrow skirting ( 2 ) firmly connected. Via a detachable connection, outlet angle adjuster ( 3 ) can influence the flow and the collection of rainwater. This device also serves for better self-cleaning and for adjusting the raindrop collector ( 1 ). The above mentioned parts are via the angle adjuster ( 3 ) with a stand ( 5 ) and a foot ( 4 ) in the vertical direction, movably connected.
