Abstract
PURPOSE: To perform a high accurate control over a humidity by a method wherein a sensed humidity and a plurality of predetermined levels are compared so as to judge the sensed humidity corresponds to which humidity range, and a dehumidification signal and a humidifying instruction signal, and a dehumidification stopping signal and a humidifying terminating instruction signal are produced in response to the result of judgement.
CONSTITUTION: Under a high humidity condition, a resistance value of a humidity sensing element 1 is decreased and a voltage Vi is increased more than a voltage Va at a connection point (a). Thus, the outputs from the comparators 6W8 are set to "1" and a high humidity range is sensed, FF circuits 21,22 are set, a dehumidifying instruction signal is produced at an output terminal of the circuit 21 and a humidifying termination instruction signal is produced at the output terminal of the circuit 20. In this way, a dehumidifying operation is performed, the voltage Vi is decreased as a humidity is decreased and when it is lower than the voltage Va, only an output from the comparator 6 becomes "0" and a medium humidity range is detected. Then, when the voltage Vi is lower than a voltage Vi at the connection point (b), a low humidity range is sensed and then a dehumidifying termination instruction signal is produced from the circuit 21.
