VALVE CONTROL METHOD OF GAS TYPE DRYER

摘要

PURPOSE: A valve control method for a gas type dryer is provided to control the amount of gas supplied to a gas combustion chamber. CONSTITUTION: A valve control method for a gas type dryer controls a gas valve according to the temperature of a discharging unit which discharges hot wind(S20). The gas valve comprises a proportional control valve which controls the amount of gas supplied to a gas combustion chamber. When the temperature of an inlet is more than the inlet control temperature and the temperature of an outlet is less than the valve close control temperature(S30), the proportional control valve lowers openness(S40).
