——drum washing machine: washing machine in which the laundry is placed in the drum, partially immersed in water, and washed by the continuous rotation of the drum or regular forward and backward rotation.
——agitator washing machine: washing machine in which the laundry is totally or partially immersed in the washing water and washed by the reciprocating motion of the stirring blades.
——double-drive washing machine: washing machine in which the laundry is completely or partially immersed in the washing water, and washed by the running of the impeller or stirring blade and the inner drum, driven by power in the same system, according to the set constant speed and constant speed ratio.
Note 2: Electric washing machines are divided into the following types by the automation degree and basic structure:
——washing machine: washing machine with washing, rinsing and spinning functions switched by manual operation.
