The invention discloses a large automatic ultrasonic dish washing machine. The large automatic ultrasonic dish washing machine comprises an ultrasonic washing tank, an air-drying tank and a collecting tank in sequence from front to back. The ultrasonic washing tank is internally provided with ultrasonic emitting head devices and a driving device, and the driving device is connected with the ultrasonic emitting head devices and used for driving the ultrasonic emitting head devices to work. Each ultrasonic emitting head device comprises an ultrasonic transducer and a high pressure air nozzle which enables input high pressure air to form bubbles in a cleaning fluid, each ultrasonic transducer is used for providing energy for the cleaning fluid, the bubbles in the cleaning fluid are broken to produce an impact force, and the impact force is utilized for washing dishes to be washed. The large automatic ultrasonic dish washing machine is simple and exquisite in structure and is used for washing dishes and the like; the high pressure gas is introduced, the strength of ultrasonic waves produced by the emitting head devices is high, the impact force and friction force of the ultrasonic waves produced by breaking of the bubbles are large, no surfactant or detergent is needed, the effect is good, and environmental protection and sanitation are achieved.
