Abstract
An automatic control for a clothes dryer embodying microcomputer controlled apparatus adapted to maintain optimum drying efficiency with minimum risk to the clothes fabrics. The control operates the dryer at maximum heat input rate and a minimum or normal low air flow rate through the drum during the initial warm-up period and the ensuing period during which the moisture removal rate is relatively constant. During these periods, the inlet temperature is monitored and when it exceeds a 'fabric-safe' level, the air flow rate is increased and the heat input is reduced preferably after an established time delay to alow conditions to stabilize in the drum after the air flow rate is increased. The control is responsive to outlet air temperature to sense when the moisture removal begins declining to maintain the air flow at the normal low rate, selectively reducing the heat input rate only as needed as determined by the inlet air temperature for safe fabric conditions until the clothes are dry and the drying cycle is terminated.
