The invention relates to a dish-washing machine mainly comprising a casing, an air compressor, a dry ice storage device, a pipeline, a filter, a pressure-reducing valve, a mixer, a tableware rack, a nozzle, a control device and a drain device and the like. The dish-washing machine is advantaged in that the dish-washing machine is a green, environmentally-friendly and novel dish-washing machine, compressed air serves as power and a carrier, dry ice serves as a washing medium, the compressed air accelerates the dry ice, the dry ice is sprayed from the nozzle and impacts the tableware surface to be washed, by means of energy conversion of momentum change, sublimation, fusion and the like of the high-speed moving dry ice, dirt, oil stains, residual impurities and the like on the tableware surface to be washed are frozen quickly, and are congealed, embrittled and stripped, and are removed along with air flow at the same time. The tableware surface, especially the ceramic fine surface is not damaged at all, and the surface smoothness is not affected. The dish-washing machine can wash tableware cleanly, efficiently and quickly, the washing agent does not need to be added, secondary pollution is not generated, and the dish-washing machine is power-saving and water-saving, and is wide in application scope, and can be applied to big and small hotels, dining rooms, houses and the like.
