Abstract
PURPOSE: To improve safety and sensitivity by using a particular forced intake and exhaust fan control circuit.
CONSTITUTION: A control circuit 5 for a forced intake and exhaust fan 20 comprises a switch 21 for a relay 43 having a normally closed contact connected to a low air rate terminal 20b of the forced intake and exhaust fan 20 and a normally open contact connected to a high air rate terminal 20a of the fan and a switch 22 for a relay 28 having a normally open contact connected to the common contact of the switch 21 and a common terminal connected to an operating switch 4. In a low temperature state of a temperature detecting element 40, by closing a power source switch 2 and the operating switch 4 a transistor 27 in a drive circuit 7 is turned on to actuate the relay 28 and close the switch 22, thus causing the forced intake and exhaust fan 20 to be slowly rotated to operate a low rate combustion electromagnetic valve 14 so that low rate combustion is obtained. At the time of a high temperature, a transistor 42 in a drive circuit 9 is turned on to actuate the relay 43, thus switching the switch 21 to the side of the high air rate terminal 20a to actuate a high rate combustion electromagnetic valve 15 so that high rate combustion is obtained.
