Abstract
PURPOSE: To improve durability while eliminating false operation by dew condensed water, etc., and to compact the whole combustion machine, by applying a Hall effect element for detecting revolution.
CONSTITUTION: A Hall IC12 is mounted which incorporates a Hall effect element to a permanent magnet 11 installed to a shaft of a fan. When the fan is turned, square waves with frequency corresponding to the number of revolution are generated from the Hall IC12, and the output passes through a condenser 13, is smoothed by means of a diode (D1)14 and a condenser (C2)15 and is applied to a comarator 16 as direct current input. When the input exceeds compartor reference input 17, the output 18 of the comparator attains a high level, a transistor (TR1)19 is driven and a relay RY20 is energized. Thus, a control circuit 22 controls a magnet valve 23, and combustion and other functions are stopped.
