摘要： The present invention is a warm-air machine control apparatus which is capable of blowing warm air from the beginning of the delivery of air without preheating an electric heater, and which comprises an electric fan (4), an electric heater (5) which heats air sent from the electric fan (4), a detector (7) which detects a first object to be detected within a first detecting range (a, c) and which also detects a second object to be detected within a second detecting range (b, d), and a control circuit which energizes the electric heater (5) when the detector (7) detects the first object of detection within the first detecting range (a, c), and which energizes the electric fan (4) when the detector (7) detects the second object of detection within the second detecting range (b, d).
