The invention discloses a main control board circuit of a full-automatic pancake baking
machine, which relates to the field of pancake baking machines and comprises a power supply module, a sensor control module, a
silicon controlled
rectifier control module and a display control board, wherein the sensor control module, the
silicon controlled
rectifier control module and the display control board are all electrically connected with the power supply module; and the display control board is electrically connected with the sensor control module. According to the main control board circuit of the full-automatic pancake baking
machine, after an operation instruction is given out through the display control board, a first main control
chip in the sensor control module receives a
signal and transmits the
signal to a second main control
chip through communication, and the second main control
chip drives on-off of a
silicon controlled
rectifier by giving a high-low level driving
signal to a Darlington tube, and thus, the motor and the heating tube are thus controlled to work; the motor works to a designated position, the operation is simple and convenient, pancakes can be automatically made, and the time of the pancake baking
machine can be automatically controlled when the pancakes are baked.
