PURPOSE: A method and device for control of popcorn vending machine are provided to control driving voltage of a heat supplying device according to the change of input voltage and environmental temperature to cook popcorns in a constant condition. CONSTITUTION: The device for control of popcorn vending machine comprises an input AC voltage detecting means for converting input alternate current voltage to direct current voltage having a certain level for detecting a change of the input AC voltage; a sensor to detect a temperature surrounding the popcorn vending machine; a control means to output switching control signals to connect/disconnect an input/output tab of a transformer for driving a heater, wherein, the sensor outputs the detected results to the control means; a motor for supplying wind towards a cook chamber under control of the control means for evenly transmitting heat to popcorns during cook and remove residue and; a switching means of input/output tab for connecting/disconnecting the input/output tab of the transformer for driving the heater according to the switching control signals. |
