Large automatic ultrasonic dish washing machine

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of dishwashers, in particular to a large-scale ultrasonic automatic dishwasher. Background technique [0002] At present, there are spray type, eddy current type and ultrasonic type in the dishwashers on the market. The spray and vortex cleaning effects are not ideal, and the water consumption is large. For ultrasonic dishwashers, the cleaning medium is the main body of city water. In theory, the high-frequency ultrasonic waves generated by the ultrasonic generator, the impact force and friction force of ultrasonic wave vibration transmission, will remove the stains on the clothes in the tap water in the inner cylinder of the purification equipment. At the same time, in order to enhance the washing effect, the bubble generator is combined to generate air bubbles, and the air bubbles are crushed to enhance the washing effect. [0003] However, the ultrasonic probes of ultrasonic automatic dishwashers curren...

AI Technical Summary

Problems solved by technology

[0003] However, the ultrasonic probes of ultrasonic automatic dishwashers currently have low ultrasonic intensity and small number of air bubbles per unit volume, small impact force and friction force of vibration transmission, and few air bursts between ultrasonic waves and air bubbles per unit volume. Furthermore, the air explosion force formed is small, and the ultrasonic cleaning effect cannot be fully exerted, and the assistance of surfactant or detergent is needed, otherwise it is difficult to clean thoroughly
