Definitions
- the invention relates to a tubular heater according to the preamble of claim 1.
- the invention is based on the object to improve tubular radiators with overheating protection so that the Response characteristic is the same.
- the ring lies directly on the tubular heating element jacket, there is a defined temperature gradient from the heating coil to the jacket tube. Accordingly, the temperature gradient increases by a precisely defined amount when the heating coil overheats, so that the response characteristic of the relay circuit is clear.
- the figure shows a cross section through the tubular heater end.
- a heating coil 3 embedded in insulating material 2, the end of which is pushed onto the conical connecting bolt 4 and fixed, for example, by welding.
- a central part 5 of the connecting bolt 4 is passed through a ring 6, which contains resistance elements with positive or negative temperature gradients, which are connected via a line 7 to a relay circuit, not shown.
- Such relay circuits are e.g. already included in new washing machines. You can use various functions such as exercise temperature monitoring.
- the outward end 8 of the connecting bolt is held by an insulating bead 10.
- the space between the ring 6 and the insulating bead 10 is filled with a potting compound 11.
- the overload protection works as follows:
- heating coil 3 heats up above its set temperature for any reason, this inevitably leads to a defined temperature increase in the ring 6.
- the resistance drops, so that there is a greater current flow through line 7 and the relay responds.
- the heating coil is then preferably switched off in two poles.
- the ring 6 can be divided. It can also be replaced by individually arranged heat sensors.
