Description
Elektrisch beheizter RadiatorElectrically heated radiator
Die Neuerung betrifft einen in Form eines Radiators gestalteten, mit Flüssigkeit gefüllten, elektrisch beheizten Heizkörper gemäß dem Oberbegriff des Schutzanspruchs 1.The innovation relates to an electrically heated radiator designed in the form of a radiator, filled with liquid, according to the generic term of claim 1.
Derartige Radiatorheizkörper dienen vorzugsweise zur Beheizung von Wohnräumen, insbesondere von Badezimmern od. dergl., entweder als Direktheizung oder aber auch als Zusatzheizung.Such radiators are primarily used to heat living spaces, especially bathrooms or similar, either as direct heating or as additional heating.
Zur Beheizung dieser flüssigkeitsgefüllten Heizkörper als solche sind elektrische Rohrheizkörper vorgesehen, die ihre Wärme an die im Radiator enthaltene Flüssigkeit übertragen, die diese Wärme schließlich über die Gehäusewand an die Umgebung abgibt.To heat these liquid-filled radiators as such, electric tubular heaters are provided, which transfer their heat to the liquid contained in the radiator, which finally releases this heat to the environment via the housing wall.
Es ist bekannt, die genannten Rohrheizkörper mit Temperaturbegrenzern gegen Überlastung, z. B. durch "Trockengehen" abzusichern. Dies geschieht beispielsweise bei Radiatoren mit flachem Aufbau, der aus aneinandergefügten Rohrstücken gebildet ist, dadurch, daß in die länglichen, patronenförmigen Heizelemente Thermobimetallregler und/oder Schmelzlotsicherungen, eingebaut werden.It is known to protect the above-mentioned tubular heaters with temperature limiters against overload, e.g. by "running dry". This is done, for example, in radiators with a flat structure, which is made up of pipe sections joined together, by installing thermobimetal regulators and/or fusible link fuses in the elongated, cartridge-shaped heating elements.
Auf die meist sehr unterschiedlichen Betriebszustände reagieren diese Sicherungen jedoch nicht immer optimal. Insbesondere die Schmelzsicherungen haben den Nachteil, daß schon eine einmalig auftretende thermische Überlastung zum Ausfall der betreffenden Heizelemente führt. Zum andern ist die Lebensdauer dieser Heizelemente begrenzt, weil die elektrischen Kontakte des Bimetallreglers infolge des häufigen Schaltens mehr oder weniger rasch abgenützt werden.However, these fuses do not always react optimally to the often very different operating conditions. The fuses in particular have the disadvantage that even a single thermal overload can lead to the failure of the heating elements in question. On the other hand, the service life of these heating elements is limited because the electrical contacts of the bimetal regulator wear out more or less quickly as a result of the frequent switching.
Aufgabe der vorliegenden Neuerung war es nun, die genannten Nachteile zu beheben und den Radiator mit wenigstens einem patronenförmigen Heizkörper auszurüsten, bei dem, unter Verwendung relativ einfacher Mittel, eine vorbestimmte Temperatur nicht überschritten wird.The aim of the present innovation was to eliminate the disadvantages mentioned and to equip the radiator with at least one cartridge-shaped heating element in which, using relatively simple means, a predetermined temperature is not exceeded.
Diese Aufgabe wird durch die kennzeichnenden Merkmale des Schutzanspruchs 1 gelöst.This problem is solved by the characterizing features of claim 1.
Mit diesem neuartigen Aufbau des Radiators kann einmal die vorgegebene Höchsttemperatur nicht überschritten werden und zum andern wird bei Inbetriebnahme des Radiators, infolge der nicht linearen Kennlinie der PTC-Elernente der Anheizvorgang beschleunigt, während andererseits im Falle eines "Trockengehens" die Leistungsaufnahme bis auf eine geringe Ruheleistung gedrosselt wird.With this new design of the radiator, the specified maximum temperature cannot be exceeded and, when the radiator is switched on, the heating process is accelerated due to the non-linear characteristic curve of the PTC elements, while, in the event of "running dry", the power consumption is throttled down to a low idle power.
Eine weiterer Vorteil dieser Bauart kann noch darin gesehen werden, daß die Lebensdauer der PTC-Elemente als solche praktisch unbegrenzt ist.A further advantage of this design is that the service life of the PTC elements as such is practically unlimited.
Der Gegenstand der Neuerung ist in einem Ausführungsbeispiel in der Zeichnung, teilweise im Schnitt, dargestellt.The subject of the innovation is shown in an embodiment in the drawing, partly in section.
Der dargestellte Radiator-Heizkörper besteht aus einem flachgestalteten Gehäuse 1, das-aus einer Mehrzahl zusammengefügter Rohrstücke 2 gebildet wird. Die wagrechten Rohrstücke 2 sind an beiden Enden mit den senkrechten Rohrstücken 3 verschweißt, derart, daß die Enden der wagrechten Rohrstücke 2 sich mit entsprechenden, in den senkrechten Rohrstücken angebrachten Bohrungen 4 decken. In einem der beiden senkrechten Rohrstücke 3 ist ein als Patrone ausgebildetes Heizelement 5 eingeschoben und an.seinem unteren Ende mit dem unteren Ende des senkrechten Rohrstücks verschraubt.The radiator shown consists of a flat housing 1, which is made up of a plurality of pipe sections 2 joined together. The horizontal pipe sections 2 are welded to the vertical pipe sections 3 at both ends, in such a way that the ends of the horizontal pipe sections 2 coincide with corresponding holes 4 in the vertical pipe sections. A heating element 5 designed as a cartridge is inserted into one of the two vertical pipe sections 3 and is screwed at its lower end to the lower end of the vertical pipe section.
Dieses Heizelement 5 enthält ein oder mehrere übereinander angeordnete PTC-Elemente, deren Anschlußleiter 6 nach unten aus dem Radiatorgehäuse 1 herausgeführt ist. Der innere Aufbau dieser Heizpatrone 5 ist'«rtan sich bekannter Weise durch Querschnittsverminderung verdichtet.This heating element 5 contains one or more PTC elements arranged one above the other, the connecting conductor 6 of which is led downwards out of the radiator housing 1. The internal structure of this heating cartridge 5 is compressed in a known manner by reducing the cross-section.
Um den Radiator ggf. auch als Zusatzheizung an eine Zentralheizung od. dgl. anschließen zu können, sind an beiden senkrechten Rohrstücken 3 je ein Anschlußnippel 7 und 8 vorgesehen, die in das Rohrsystem des Radiators münden. Diese Bauart ermöglicht auch einen sehr zweckmäßigen Sommerbetrieb, bei dem nur die zuvor beschriebene elektrische Heizung aktiviert zu werden braucht.In order to be able to connect the radiator to a central heating system or similar as an additional heater, a connection nipple 7 and 8 are provided on both vertical pipe sections 3, which lead into the pipe system of the radiator. This design also enables very practical summer operation, in which only the previously described electric heater needs to be activated.
