Through a high pressure or low-pressure environment of at least one time and discharging gas or fluid of at least one time, not only can the dirt be discharged, but bacteria or other harmful components adhered to the clothes can also be effectively removed. Such washing method eliminates the need to dry the clothes, and after washing, the clothes can be taken out and worn, which is very convenient, prolongs the service period of the clothes, greatly reduces power consumption, and eliminates environmental pollution.

According to the above structure, since washing clothes in the high-pressure, low pressure or vacuum environment requires almost no water or very little water as a carrier, the waste of water resources is reduced, where carbon dioxide or special volatile detergent may be used as the washing gas, or industrial waste gas can be effectively utilized to improve the utilization rate of rubbish.

A high/low-pressure technology and a vibration technology of the variable-pressure washing machine can be configured on different washing machines so that the clothes can be washed only through the high-low change of the pressure or the washing function can be enhanced through the high-low change of the pressure, thereby reducing or eliminating environmental pollution.
