ABSTRACT:
In an electrical resistance heating element (1) comprising a heating conductor support (3) of insulating material and a heating conductor (4) of resistance wire wound in meander or sinuously coiled manner with loop ends or bights (6) and loop legs or runs (8), the loops of the heating conductor (4) being arranged substantially in a single plane, and the inner loop ends (6) which are directed towards the heating conductor support (3) being situated in the edge region of the heating conductor support (3), it is proposed according to the invention to construct the heating conductor support (3) as a flat plate, the flat plate to be situated substantially in the same plane as the loops of the heating conductor (4). It is also proposed that the outer loop ends or bights (5) remote from the heating conductor support (3) are to be self-supporting and not secured. Because of this arrangement a resistance heating element can be manufactured at relatively small expense from a small number of different components, with very considerable mechanisation. Such a resistance heating element is used more particularly for the heating of gaseous media in hot air appliances, such as hair dryers or the like.
