The invention provides an energy-efficient automatic cooking device and belongs to the field of food processing machines in daily life. The device comprises a furnace body, common wheels, a universal wheel, an air cylinder seat, a servo air cylinder, a connecting device, a rotary shaft, a motor seat, a first servo motor, a second servo motor, a first connecting rod, an adapter, a second connecting rod, a stirring and scooping device, a water pipe, a filter and a quick coupling. The device can freely walk through the common wheels and the universal wheel, automatic water feeding is achieved after the quick coupling and a faucet are connected, a heating device at the bottom of the inner side of the furnace body is used for heating, up-and-down motion of the stirring and scooping device is achieved through telescopic motion of the servo air cylinder, rotation of the stirring and scooping device within the vertical range is achieved through rotation of the first servo motor, and rotation of the stirring and scooping device around the rotary shaft is achieved through rotation of the second servo motor. Automatic water adding, automatic stirring after water boiling and automatic scooping and pouring after food cooking of the cooking device can be achieved, manpower and material resources are saved, and the cooking efficiency of food is improved.
