Methods for manufacturing heating coil assembly |
摘要 |
In a method of manufacturing a heating coil assembly for electromagnetic induction cooking heater in which a coil supporting base and a flat shaped coil winding frame are mounted on the spindle of a coil winding machine in such a manner as to form a coil receiving space therebetween, and a wire is wound in the space to form a coil, the coil supporting base and/or the coil winding frame has protrusions which extend in the space at the middle part, to vary the coil winding pitch, whereby the coil thus formed has a gap at the middle part, thus showing a uniform temperature distribution when energized.
