   PATENT CLAIM:
Warning device for excessive temperatures in hot water heating systems with an additional water heater and a line leading from the water heater to the consumers
 EMI1.1
 

** WARNING ** End of DESC field may overlap beginning of CLMS **.

Claims (1)

<Desc/Clms Page number 1> <Desc / Clms Page number 1> Die Erfindung betrifft eine Warneinrichtung für überhöhte Temperaturen bei Warmwasserheizungsanlagen mit Festbrennstoffen und einer vom Brauchwasserbereiter zu den Verbrauchern führende Leitung mit einem thermischen Ablaufventil. The invention relates to a warning device for excessive temperatures in hot water heating systems with solid fuels and a line leading from the domestic water heater to the consumers with a thermal drain valve. Bei Warmwasserheizungsanlagen mit Festbrennstoffen kommt es immer wieder zur Überhitzung der Heizkessel. Die Ursache liegt meistens darin, dass beim Ausfall der Heizungsumwälzpumpe (z. B. durch Stromausfall) durch das Schliessen des Mischventile oder der Heizkörperventile die gesammelte Kesselwärme nicht mehr abgeführt werden kann. Zu dieser Überhitzung kommt es auch dann, wenn der Feuerungsregler die Luftklappe schliesst (wenn z. B. die Koksfüllung vollglüht). In hot water heating systems with solid fuels, the boiler overheats again and again. The cause is usually that if the heating circulation pump fails (e.g. due to a power failure), when the mixing valve or the radiator valves close, the collected boiler heat can no longer be dissipated. This overheating also occurs when the combustion controller closes the air damper (e.g. when the coke filling is fully glowing). Gesetzlich ist zum Schutz dieser Anlagen eine thermische Ablauf Sicherung vorgeschrieben. Diese Vorrichtung hat die Aufgabe, beim Erreichen der eingestellten Höchsttemperatur des Kesselwassers (zirka 95 C) das Wasser des Brauchwassererzeugers in einen Ablauf abzuleiten. Durch Nachspeisen von kaltem Leitungswasser arbeitet dieser nun als Wärmetauscher und leitet die Überwärme in den Ablauf ab. A thermal discharge fuse is required by law to protect these systems. This device has the task of draining the water from the domestic water generator into a drain when the set maximum boiler water temperature is reached (approx. 95 C). By adding cold tap water, it now works as a heat exchanger and dissipates the excess heat into the drain. Es kann nun vorkommen, dass nicht bemerkt wird, wann die Übertemperatursicherung anspricht. It can now happen that it is not noticed when the overtemperature protection is triggered. Dabei wird kostbare Energie in den Ablauf geleitet oder die Wärmeabfuhr reicht nicht aus, um den Kessel vor Überhitzung zu schützen. Valuable energy is channeled into the drain or the heat dissipation is insufficient to protect the boiler from overheating. Der Erfindung liegt daher die Aufgabe zugrunde, bei einer Einrichtung der eingangs genannten Art ein von der elektrischen Energie unabhängiges zusätzliches Warnsystem vorzusehen. The invention is therefore based on the object of providing an additional warning system that is independent of the electrical energy in a device of the type mentioned at the beginning. Eine derartige Einrichtung ist gemäss der Erfindung derart ausgebildet, dass auf der Austrittsseite des thermischen Ablaufventiles ein Venturisaugfitting mit einer Warnpfeife angeordnet ist. Such a device is designed according to the invention in such a way that a venturi suction fitting with a warning whistle is arranged on the outlet side of the thermal drain valve. An Hand der Zeichnung wird die Erfindung näher erläutert. Die Zeichnung zeigt eine Heizungsanlage mit zusätzlicher Warneinrichtung in schematischer Darstellung. The invention is explained in more detail with reference to the drawing. The drawing shows a heating system with an additional warning device in a schematic representation. Die in der Zeichnung dargestellte Warmwasserheizungsanlage weist einen Kessel --1-- mit einer Heizungsvorlaufleitung --7-- und einer Heizungsrücklaufleitung --8--, sowie einen Brauchwasserbereiter - mit einer Kaltwasserzuleitung --9-- und einer von diesem zu den Verbraucher führenden Warmwasserleitung-3-auf. The hot water heating system shown in the drawing has a boiler --1-- with a heating flow line --7-- and a heating return line --8--, as well as a water heater - with a cold water supply line --9-- and one of this to the consumer leading hot water pipe-3-on. In einer Verbindungsleitung --10--, die zwischen der Warmwasserleitung --3-- und einem in einen Kanal mündenden Abfluss --11-- angeordnet ist, ist ein nach den gesetzlichen Bestimmungen vorgesehenes thermisches Ablaufventil --4-- und nachgeordnet ein Venturisaugfitting --5-- mit einer Warnpfeife --6-vorgesehen. Beim Ansprechen des Ablaufventiles --4-- fliesst das Wasser des Brauchwasserbereiters --2-durch den Venturisaugfitting --5--, der Luft durch die Warnpfeife --6-- ansaugt, welche dabei ein Pfeifgeräusch erzeugt. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. In a connecting line --10--, which is arranged between the hot water line --3-- and a drain --11-- which opens into a channel, there is a thermal drain valve --4-- and a downstream one Venturi suction fitting --5-- with a warning whistle --6-provided. When the drain valve --4-- responds, the water from the domestic water heater --2- flows through the venturi suction fitting --5--, which sucks in air through the warning whistle --6--, which generates a whistling sound. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
