Abstract
PURPOSE: To increase the safety and reliability remarkably with a simple constitution, by ensuring to blow down the temperature fuse through efficient indirect heating, at the short circuit of control rectifying element controlling the power application to heating wire, in the electric heating apparatus such as electric carpet.
CONSTITUTION: If the SCR17 is short-circuited due to any cause, the SCR28 is conductive at negative half cycle of the AC power input 1. Further, the main current of SCR28 flows to the closed circuit of power input 1-SCR7-resistor 26- SCR28-temperature fuse 3-power switch 2-power supply 1. This current heats up the resistor 26, indirectly heating the fuse 3 located near the resistor 26 for mounting. Thus, with a simple constitution, the safety and the reliability can remarkably be improved.
