Specifically, when washing clothes, the washing machine controls to start the gas generating device and work for T1 time, so that stains are prevented from being attached to the washing barrel 1 and the impeller, and the washing water and the washing clothes can be sterilized and disinfected by selectively introducing gas with a disinfection function. The operation time T1 is determined according to the laundry amount and the washing water level. In the invention, the sealing ring 91 covering the air hole can be pushed open only when the gas pressure in the gas channel is greater than the sum of the washing water pressure and the spring elasticity, so that the gas is introduced into the washing barrel, therefore, the gas generating device needs to overcome the washing water gravity and the spring elasticity to do work, the control of the T1 time of the work of the gas generating device 3 in the washing process is beneficial to reducing the extra work of the gas generating device and preventing the overload of the gas generating device, and simultaneously, the energy loss is reduced.
Preferably, when the water is drained for the last time, the gas generating device 3 is controlled to be started, the bubbles formed in the washing barrel 1 are diffused from the middle of the bottom of the washing barrel to the periphery, the bubbles impact the back of the whole impeller and the bottom of the washing barrel to generate an impact force of thousands of atmospheres, so that the dirt on the back of the impeller and the washing barrel is peeled off, and the peeled dirt is drained out of the washing machine along with the washing water. The control method of the invention can realize cleaning in the last drainage, save the cleaning time, greatly reduce the using amount of the washing water, and simultaneously has high cleaning efficiency and no dead angle in cleaning.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
