According to the control method of the washing machine, after the washing barrel 2 is filled with water, the washing machine controls the gas supply device 6 to introduce gas into the washing barrel 2, and tumbling water flow is formed in the washing water to wash the washings. The washing mode has good washing effect, and the washings are not easy to wind and have small damage to the washings.
As an embodiment of the invention, the washing machine introduces compressed air into the washing barrel 2 while feeding water, and stirs the washing mixture to make the detergent uniformly distributed, which is beneficial to improving the decontamination effect in the washing process.
As another embodiment of the present invention, after the air supply device 6 starts to operate, the top cover 1 is intermittently opened, the pressure in the washing tub 2 can be rapidly reduced by opening the top cover 1, thereby preventing the washing efficiency from being reduced due to the difficulty in air intake of compressed air caused by the excessive pressure in the washing tub, and the washing water can be prevented from splashing by closing the top cover 1.
Further, after the washing tub 2 finishes draining, the washing machine controls to open the air supply device 6 and the drying device 8, the air supply device 6 and the drying device 8 cooperate to generate high-temperature and high-pressure drying air, and the high-temperature and high-pressure drying air is introduced into the washing tub 2 to dry the washed objects.

The drying device 8 can be opened to quickly raise the temperature in the washing tub 2, so that the water of the washings is evaporated, and the drying efficiency can be effectively improved.
According to some embodiments of the invention, the washing process is as follows:
s1, putting the washings into the container, and injecting washing water into the container;
s2, controlling the heating device to heat the washing water to a set temperature;
s3, controlling the gas supply device to provide gas with certain pressure, and forming tumbling water flow in the washing water to wash the washed objects;

and S5, after the washing tub drains, the washing machine controls to start the air supply device and the drying device, and the air supply device and the drying device are matched to generate high-temperature and high-pressure drying air which is introduced into the washing tub to dry the washed objects.
Further, the pressure of the gas supplied to the washing tub 2 by the gas supply device 6 in the washing process is smaller than the pressure of the gas supplied to the washing tub 2 by the gas supply device 6 in the drying process. The gas pressure in the washing process only needs to meet the pressure capable of generating rolling water flow, so that the damage to the washed objects can be reduced; the drying process requires that the damp washings are blown up and scattered to realize the drying of the washings, and the drying efficiency can be improved by improving the gas pressure.
