Description
Elektrischer Heizapparat für Flüssigkeiten. Gegenstand vorliegender Erfindung ist ein elektrischer Heizapparat für Flüssigkei ten, der sich dadurch auszeichnet, da.ss' ein bandförmiger, spiralförmig um da Abfluss- rohr gewundener elektrischer Heizkörper einen von der Flüssigkeit durchströmten Ka nal bildet, über welchem der mit einem den Heizstromkreis beherrschenden Schalter ver bundene Einlasshahn angeordnet ist, wobei als Schutz gegen Wärmeverluste durch die äussere Wandfläche des Apparates minde stens die äusserste Windung des Heizkörpers als blosses Metallband ohne Heizwiderstand ausgebildet ist.
Auf beiliegender Zeichnung ist beispiels weise eine Ausführungsform des Erfindungs gegenstandes dargestellt, und zwar in Fig. 1 durch einen senkrechten Mittel schnitt, und in Fig. 2 durch einen Querschnitt.
Nach Zeichnung ist ein elektrischer Heiz körper, der aus einer zwischen zwei Metall bändern 1 in einer Isoliermasse 2 eingebette ten, nicht besonders dargestellten Heizdraht- Wicklung besteht, spiralförmig so um ein Abflussrohr 3 gewunden, dass dadurch ein spiralförmiger Kanal 4 gebildet wird, der seinen Austritt im Schlitz 5 besitzt und sei nen Eintritt im Schlitz 9 und vom Zufluss- rohr 6 her durch einen Absperrhahn 7 und einen die Decke des Kanals 4 bildenden Kaltwasserzwischenraum 8 hindurch ge- spiesen wird. Der Schlitz 5 ist so,
hoch an geordnet, dass der spiralig gewundene Kanal nach dem Abstellen der Wasserzufuhr noch grösstenteils mit Flüssigkeit gefüllt bleibt. Gleichachsig mit dem Hahn ist ein elektri scher Stromschalter 10 angeordnet, der bei geschlossenem Hahn auch den Heizstromkreis unterbrochen hält.
Sowohl der spiralig gewundene Heiz körper 1, 2, als auch der Zwischenraum 8 und der Hahn 7 samt Schalter 10 sind in einem Gehäuse 11 eingeschlossen. Zwischen der Gehäusewand und dem Heizkörper kann Isoliermasse eingefüllt sein.
Zur Erzielung der gleichen Wirkung könnte auch die Wand des Gehäuses 11 mehr- wandig sein. Die äusserste Windung der Spirale trägt hier keinen Heizwiderstand, son dern nur ein Metallband. Man könnte sich auch so einrichten, dass die zwei oder sogar die drei äussersten Windungen der Spirale ohne Heizwiderstand sind.
Als Schutz gegen Überhitzung bei Was sermangel ist in dem Heizstromkreis eine nicht gezeichnete, aus leicht schmelzbarer Legierung bestehende Sicherung eingebaut.
Electric heating apparatus for liquids. The subject of the present invention is an electric heater for liquids, which is characterized by the fact that a ribbon-shaped electric heater wound in a spiral around the drainpipe forms a channel through which the liquid flows, over which the switch with a heating circuit dominating ver related inlet tap is arranged, with at least the outermost turn of the radiator being designed as a mere metal strip without a heating resistor as protection against heat loss through the outer wall surface of the apparatus.
In the accompanying drawing, an embodiment of the subject invention is shown as an example, in Fig. 1 by a vertical center, and in Fig. 2 by a cross section.
According to the drawing, an electric heating body, which consists of a heating wire winding embedded between two metal strips 1 in an insulating compound 2, not specifically shown, is wound around a drain pipe 3 in a spiral shape so that a spiral channel 4 is formed, which is his It has an outlet in the slot 5 and its inlet in the slot 9 and from the inlet pipe 6 through a shut-off valve 7 and a cold water gap 8 forming the ceiling of the channel 4. The slot 5 is like this
in a high order that the spirally wound channel remains largely filled with liquid after the water supply has been turned off. Coaxially with the tap, an electrical current switch 10 is arranged, which keeps the heating circuit interrupted when the tap is closed.
Both the spirally wound heating body 1, 2 and the space 8 and the tap 7 together with the switch 10 are enclosed in a housing 11. Insulating compound can be filled between the housing wall and the heating element.
To achieve the same effect, the wall of the housing 11 could also be multi-walled. The outermost turn of the spiral does not have a heating resistor here, but only a metal band. One could also arrange in such a way that the two or even the three outermost turns of the spiral have no heating resistance.
To protect against overheating in the event of a lack of water, a fuse, not shown, made of easily fusible alloy, is installed in the heating circuit.
