BrauchwassererwärmerDomestic water heater
Die Neuerung betrifft einen Brauchwassererwärmer nach dem Oberbegriff des Schutzanspruches 1.The innovation concerns a domestic water heater according to the generic term of claim 1.
Es gibt Brauchwassererwärmer, bei denen das Wasser direkt durch die Heizeinrichtung erwärmt wird und solche, bei denen eine indirekte Erwärmung über Heizwasser erfolgt. Bei der indirekten Beheizung kennt man Speichererwärmer und Durchlauferwärmer. Durchlauferwärmer sind solche, bei denen eine Brauchwasserschlange in einem Heizwasserspeicher angeordnet ist. Zum Erzielen einer effektiven Brauchwassererwärmung muß während der Brauchwasserentnahme eine Nachheizung über eine zugeordnete Heizeinrichtung erfolgen. Zu diesem Zweck ist üblicherweise ein Temperatursensor im Heizwasserspeicher angeordnet der in Abhängigkeit von der Heizwassertemperatur auf die Steuerung der Heizeinrichtung einwirkt.There are domestic water heaters in which the water is heated directly by the heating device and those in which heating is done indirectly via heating water. Indirect heating is known as storage heaters and instantaneous water heaters. Instantaneous water heaters are those in which a domestic water coil is arranged in a heating water storage tank. To achieve effective domestic water heating, additional heating must be carried out via an associated heating device while the domestic water is being used. For this purpose, a temperature sensor is usually arranged in the heating water storage tank, which influences the control of the heating device depending on the heating water temperature.
Der Neuerung liegt die Aufgabe zugrunde, eine Anordnung für den Temperatursensor zu schaffen, die ein sehr schnelles Ansteuern der Heizeinrichtung bei einem auftretenden Wärmebedarf bewirkt.The innovation is based on the task of creating an arrangement for the temperature sensor that enables the heating device to be activated very quickly when heat is required.
Der neuerungsgemäße Brauchwassererwärmer besitzt die im Schutzanspruch 1 genannten Merkmale.The domestic water heater according to the innovation has the features mentioned in claim 1.
• · I· I
Der Temperatursensor sitzt nicht im Heizwasserspeicher, um auf dessen Temperatur anzusprechen. Hier dauert es nämlich eine gewisse Zeit, bis ein Heizwärmebedarf erfaßt und an die Steuerung der Heizeinrichtung weitergegeben wird. Stattdessen ist der Temperatursensor im Einmündungsbereich der Brauchwasserschlange in den Heizwasserspeicher angeordnet, und zwar in einem gut wärmeleitenden mit der Brauchwasserschlange in direktem Wärmekontakt stehenden Metallkörper. Sofort nach dem Zapfbeginn strömt hier kühles Frischwasser vorbei. Bereits ein geringer Temperaturabfall überträgt sich auf den Metallkörper und auf den Temperatursensor , so daß er unverzüglich zur Steuerung der Heizeinrichtung dienen kann. Somit erfolgt die weitere Wärmezufuhr zum Heizwasserspeicher in direkter Folge zur beginnenden Brauchwasserentnahme. Um Wärmeabstrahlungen von dem aus Kupfer bestehenden Metallkörper zu vermeiden, die das sofortige Erfassen der abfallenden Temperatur durch den Temperatursensor verschlechtern könnte, sollte dieser von einer Wärmedämmung umgeben sein.The temperature sensor is not located in the heating water tank to respond to its temperature. Here it takes a certain amount of time until a heating requirement is detected and passed on to the control of the heating system. Instead, the temperature sensor is located in the area where the domestic water coil enters the heating water tank, in a metal body that conducts heat well and is in direct thermal contact with the domestic water coil. Immediately after the water is drawn off, cool fresh water flows past here. Even a small drop in temperature is transferred to the metal body and to the temperature sensor, so that it can immediately be used to control the heating system. This means that further heat is supplied to the heating water tank as a direct result of the domestic water being drawn off. In order to avoid heat radiation from the metal body made of copper, which could impair the immediate detection of the falling temperature by the temperature sensor, it should be surrounded by thermal insulation.

Im Heizwasserspeicher 1 mit einer nicht dargestellten Heizeinrichtung sitzt eine Brauchwasserschlange 2. An deren Einmündungsbereich ist ein Temperatursensor 3 angeordnet. Dieser ragt mit seiner Spitze in das durchströmende Brauchwasser hinein. Im übrigen ist er in einen Metallkörper 4 eingebettet, der mit der Brauchwasserschlange 2 in gut wärmeleitender Verbindung steht. Auf diese Weise wird ein Temperaturabfall bei einströmendem kühlem Frischwasser sofort erfaßt und zur Einschaltung der Heizeinrichtung genutzt. Der Metallkörper 4 ist von einer Wärmedämmung 5 umgeben.In the heating water tank 1 with a heating device (not shown) there is a domestic water coil 2. A temperature sensor 3 is arranged at the inlet area. The tip of this extends into the domestic water flowing through. It is also embedded in a metal body 4, which is in a good heat-conducting connection with the domestic water coil 2. In this way, a drop in temperature when cool fresh water flows in is immediately detected and used to switch on the heating device. The metal body 4 is surrounded by thermal insulation 5.
