The dishwasher with the water saving function further includes a micro-bubble generator 81, a first end of the micro-bubble generator 81 is connected to the water pump 5, and a second end of the micro-bubble generator 81 is connected to a second end of the first water return pipe. The micro-bubble generator 81 generates micro-bubbles to wash the oil stain with the bubbles, so that it is unnecessary to use a pollutant such as a detergent, thereby reducing the emission of pollutants.

The dishwasher with the water-saving function not only reduces the water consumption, but also does not need to adopt polluting substances such as cleaning agents and the like, thereby reducing the emission of pollutants. The specific working process is as follows: after filling up water through inlet tube 3 toward inner bag 1, wash bowl utensil in-process, the impurity of the big granule of big granule subsides naturally (or subsides by 5 suction of water pump) and hold back and retrieve through scummer 13, and the recycled water through back scummer 13 is taken out to the second end of first circulation wet return 4 from the first end of first circulation wet return 4 by water pump 5, flow back again promptly in cavity 11, recycle the recycled water on the basis of accomplishing to detach large granule impurity promptly, thereby needn't waste excessive running water. In the recycling process of the regenerated water, a large amount of micro-bubbles can be generated through the action of the micro-bubble generator 81, so that the first spray head 41 and the second spray head 42 can spray a large amount of micro-bubbles, and the bowls are sufficiently washed; furthermore, it is thus also possible to dispense with cleaning agents, so that the emission of pollutants is reduced.

Furthermore, inside the inner container 1, because the density of grease is less than the density of water, therefore the floating oil floats on the liquid level of the inner container 1, and the floating oil on the liquid level is discharged through the overflow port 14, so that the water in the inner container 1 can be further treated completely, and the bowls can be cleaned more cleanly. After the oil-water mixed liquid discharged from the overflow port 14 and entering the overflow pipe 15 enters the oil collecting cavity 641 of the oil-water separator 6 from the liquid inlet 61 of the oil-water separator 6, because the density of the water is greater than that of the oil, the water below the oil collecting cavity 641 enters the water collecting cavity 642 through the first communication port and flows back to the first circulating water return pipe 4 under the suction force of the water pump 5, and the water also becomes a part of the regenerated water, so that the consumption of tap water is saved. Moreover, the grease can be collected into the oil collecting cavity 641 in a concentrated manner by the internal circulation, so that the liquid in the inner container 1 is gradually cleaned, and the cleaning effect is improved. Obviously, because of the washing mode of the internal circulation, and the regenerated water can be self-purified, the bowls can be cleaned up by the internal circulation washing as much as possible under the condition that the water is thoroughly changed as few as possible according to the requirements of users, and thus, the water changing times are reduced to save water.

And the first nozzle 41 is arranged on the inner side wall of the inner container 1, so that micro bubbles can be more disordered, and the bowl can be fully cleaned in all directions. More importantly, under the buffering of the first spray head 41, the second spray head 42 can be prevented from causing the impact force of the regenerated water to be too strong in order to increase the impact force, so that the floating oil can be prevented from rolling into the bottom of the liner 1 due to the too high spraying speed of the second spray head 42 (obviously, the floating oil rolling into the bottom of the liner 1 is not beneficial to the floating oil flowing into the overflow pipe 15 along the overflow port 14). That is, under the buffering of first shower nozzle 41, can be so that the all-round washing away of microbubble to bowl utensil, moreover under the offset of side direction scouring force and vertical scouring force for the grease after scouring can float to the liquid level gradually under the disorderly flow direction, thereby does benefit to the oil slick more and floats at the liquid level and to overflow mouth 14.
