ABSTRACT:
This invention relates to an electric drying apparatus automatic controller which automatically controls an electric drying apparatus in order to dry the articles put therein within a shortest period of time and with minimized power consumption. The control includes a timer, a humidity controller, and an exhaust control valve, wherein the timer is connected between the switch and the heater of an electric drying apparatus with the humidity controller and the exhaust control valve connected thereto. This controller is characterized in that the timer is preset for a certain period of heating time, to turn on the heater for heating, and starts counting time when the drying apparatus is turned on. While the timer is counting, the humidity controller can stop the timer's counting or reset the timer according to the relative humidity detected within the drying apparatus.
Also, the humidity controller opens or closes the exhaust control valve based upon the humidity within the frying apparatus. When the humidity withtin the drying apparatus reaches an amount below a fixed point (value), the humidity controller permits the timer to continue counting so as to turb the heater off after the selected time period has been exhausted. This arrangement accurately controls the amount of dryness of clothes within the drying apparatus with a minimum amount of power use.
