    • A control circuit for a drier having a heater, blower and a motor for a sensor mounted within the drier housing for determining the water content of the material therein. A desired dryness of the material is set by a manually settable control switch and a spring driven switching mechanism actuated by the control switch actuates a plurality of switches each individually controlling the heater, blower and motor. A control circuit comprises the wetness of the material within the drier with the setting of the control switch whereby the spring driven switching mechanism is unlocked to return the control switch to ''''zero'''' so as to prevent further drying of the material.
    • 一种用于干燥器的控制电路,具有加热器,鼓风机和安装在干燥器壳体内的传感器的马达,用于确定其中材料的含水量。 材料的期望的干燥度由手动设置的控制开关设定,并且由控制开关致动的弹簧驱动的切换机构致动多个开关,每个开关分别控制加热器,鼓风机和马达。 控制电路包括在控制开关的设定下干燥器内的材料的湿度,由此弹簧驱动的切换机构被解锁以将控制开关返回到“零”,以防止材料的进一步干燥。
