  • Resistance Heating (AREA)

Abstract

The heating element (1) comprises two separate electrically conductive coils (4, 11) to act as heating elements. One coil (4) supplies power to the timer control circuit by "tapping" a small amount of power from an external power supply The other coil (11) is a larger coil of greater resistance which acts as the primary heating means of the element. Pref., the coils are surrounded by quartz tube (2). One coil (4) is wound on a ceramic insulating tube with bores for the output end (5) of this coil (4) but the input end (12) of the other coil 811).
