Abstract

This heated nozzle for vehicle screen washer systems is thermostatically controlled through the thermostatic switch gear for the water inlet tube heater. The non conductive plastic body (1) contains a ball jet (2) and a water inlet shaft (3). Bedded into the body (1) is a temperature feeler (4) connected by a bridge lead (5) to the heater element (6) which is connected to the negative lead (7).S The live wires (8,9) are connected to the power source through the switch gear. This ensures that a frozen nozzle is quickly thawed out when the vehicle ignition is on and has a warning light to warn the driver of frost.

Description

Stand der Technik: Es sind Spritzdüsen bekannt, welche auf verschiedene Arten elektrisch oder durch Abgase beheizt werden.State of the art: There are spray nozzles known which on different Types to be heated electrically or by exhaust gases.

Kritik des Standes der Technik: Diese Einrichtungen sind mit dem Mangel behaftet, daß sie bei sehr niedrigen Außentemperaturen entweder zu lange brauchen um bei vollständig kaltem Fahrzeug betriebsbereit zu werden oder bei hohen Geschwindigkeiten wegen zu starker Fahrtwindkühlung und zu geringer Heizleistung wieder einfrieren. Außerdem sind Düsen nicht bekannt, welche ohne Zutun des Fahrers, allein abhängig von der Außentemperatur auf einer festgelegten Betriebstemperatur gehalten werden.Criticism of the Prior Art: These facilities are deficient afflicted that they either take too long at very low outside temperatures to be ready for use when the vehicle is completely cold or at high speeds Freeze again due to excessive airflow cooling and insufficient heating power. In addition, nozzles are not known which depend on their own without any action on the part of the driver are kept at a specified operating temperature by the outside temperature.

Aufgabe: Der Erfindung liegt die Aufgabe zugrunde, eine einfache Einrichtung zu schaffen die geeignet ist die Funktionsfähigkeit der Düsen auch bei Verwendung von reinem Wasser ohne Zusatz von Frostschutzmitteln bei jeder Temperatur unter dem Gefrierpunkt sicher zu stellen und das ohne Zutun des Benutzers der Einrichtung.Task: The invention is based on the task of a simple device to create that is suitable the functionality of the nozzles even when in use of pure water without the addition of antifreeze at any temperature below to ensure the freezing point and that without any action on the part of the user of the facility.

Lösung: Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Düsenkopf mit einem elektrischen Heizelement und mit einem Temperaturfühler versehen ist. Ein elektronisch angesteuertes Relais schaltet bei Erreichen der fest eingestellten Nindesttemperatur des Düsenkopfrs das Heizelement ein. Der Temperaturanstieg um nur einen ganz geringen Betrag bewirkt über den Fühler die sofortige Wider~ abschaltung des Heizelementes solange bis die Temperatur wieder an der unteren Grenze ist.Solution: The object is achieved according to the invention in that the nozzle head is provided with an electrical heating element and with a temperature sensor. An electronically controlled relay switches when the fixed value is reached Minimum temperature of the nozzle head for the heating element a. The temperature rise by only a very small amount causes the sensor to switch off immediately of the heating element until the temperature is at the lower limit again.

Weitere Ausgestaltung der Erfindung: Um zu verhindern daß bei Temperaturen über dem Gefrierpunkt zur Aufrechterhaltung der Düsenkopftemperatur Energie verbraucht wird ist vorgesehen, die gesamte Einrichtung mit einem Null-Grad-Hauptschalter zu versehen. Ein Thermoschalter welcher baugleich mit dem Düsenschalter sein kann, jedoch einen eigenen Fühler hat welcher irgend, wo an der Außenseite des Fahrzeuges befestigt wird schaltet bei Oo Celsius die gesamte Anlage selbsttätig ein.Further embodiment of the invention: To prevent that at temperatures Energy is consumed above freezing to maintain the nozzle head temperature It is provided that the entire facility is provided with a zero-degree master switch Mistake. A thermal switch which can be identical to the nozzle switch, however, it has its own sensor somewhere on the outside of the vehicle is attached, the entire system switches on automatically at Oo Celsius.

Erst jetzt steigt die gesamte Temperatur des Düsenkopfes und hält die dann erreichte Temperatur aufrecht.Mit der Düsenheizung parallel kann über den gleichen Stromkreis eine heizbare Schlauchleitung mit versorgt werden. Only now does the entire temperature of the nozzle head rise and hold the temperature then reached. With the nozzle heating in parallel, the A heatable hose line can also be supplied with the same circuit.

Diese Schlauchleitung wurde von mir bereits angemeldet. I have already registered this hose line.

Aktenzeichen: P 29 09 219. 1 - 22 Anmeldetag: 9.3.1979 Offenlegungstag: 11.9.1980 Der nach dieser Anmeldung notwendige Thermoschalter kann bei Verwendung der Thermostat-Spritzdüse durch den hier ebenfalls vorhandenen Therrnoschalter ersetzt werden. File number: P 29 09 219. 1 - 22 Filing date: 9.3.1979 Disclosure date: 9/11/1980 The thermal switch required after this registration can be used if the thermostatic spray nozzle is replaced by the thermal switch that is also present here will.

Weiterhin bietet sich bei Verwenduny des Null-Grdd-Huptschalters die gleichzeitige Nutzung als Frostwarner an, durch Mitschaltung einer Warn-oder Kontrollampe am Armaturenbrett. It is also possible to use the zero-degree main switch the simultaneous use as a frost warning, by switching on a warning or Control lamp on the dashboard.

Die Anlage wird nur dann mit Strom versorgt, wenn die Zündung des Fahrzeuges eingeschaltet ist und die Außentemperatur bei Oo Celsius oder darunter liegt. The system is only supplied with power when the ignition of the The vehicle is switched on and the outside temperature is Oo Celsius or below lies.

Erzielbare Vorteile: Die mit der Erfindung erzielbaren Vorteile liegen darin, daß die besonders frostempfindlichen Teile von Scheibenwaschanlagen, falls diese während des Stillstandes des Fahrzeuges eingefroren sind, nach Einschalten der Zündung so Fort aufgetaut werden und für die Zeit des Betriebes am l:inFrieren gsehinclert werden. Außerdem kann Frostschutzmittel eingespart oder auch vergessen werden.Achievable Advantages: The advantages that can be achieved with the invention are that the particularly frost-sensitive parts of windscreen washer systems, if these are frozen while the vehicle is at a standstill, after switching on the ignition so continue to be thawed and for the time of operation on the l: to be seen in the freeze. In addition, antifreeze can be saved or also be forgotten.
