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 jacket tube 1 there is 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: There is a defined heat flow from the heating coil 3, the bolt parts 4 and 5 via the ring 6 to the casing tube 1. Since the area of the casing tube at the level of the ring 6 is no longer heated, it remains free of lime deposits, so that a defined one Heat drain results.
heating coil 3 heats up above its set temperature for any reason, this inevitably leads to a defined temperature increase in the ring 6. If resistors with a positive temperature coefficient are used, 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.
