Abstract

A clothes dryer has a degree of dryness control system that is responsive to moisture level of clothing articles tumbling in a drum and a target moisture value to control the drying cycle of the clothes dryer. The clothes dryer has a load size parameter producing module and an air flow detection parameter module. These modules generate one of two parameter conditions used by the processor to modify or select an appropriate moisture target value. The load size producing parameter module generates one of a small load input parameter and a large load input parameter. The air flow detection module produces one of a first and second air flow parameter to be utilized by the degree of dryness processor. As a result, the processor selects one of four target moisture values from these conditions.
