CONTROL CIRCUIT FOR RUNNING A HEATER OF ELECTRIC HOME APPLIANCES

摘要

Provided is a heater driving circuit of electric home appliances. The heater driving circuit uses an analog circuit including an operational amplifier to output a driving control signal for a heater installed in the electric home appliances by receiving and comparing voltage outputted by detecting changes of outdoor temperature and indoor temperature with a reference voltage. The heater driving circuit controls the heater according to the temperature change without an expensive microcomputer, time for developing a circuit can be reduced, the circuit is simple, and costs are remarkably saved because of cheap components.
