Abstract

The invention relates to an improvement of rotary drums of a single-drum roller washing machine capable of washing clothes according to different classes. When washing clothes, people always hope that underwear, outerwear, fading clothes and clothes of adults and kids can be washed separately to avoid cross contamination and coloration among the clothes; people can only wash the clothes of one class first and wash the clothes of another class second by using the conventional single-drum roller washing machine; therefore, water, electricity and time are wasted and the whole washing process requires manual intervention, so inconvenience is brought to users. A dismountable partition plate 22 is added in a single-drum roller 21, so that an inner space of the single-drum roller 21 is partitioned into two independent washing spaces with different sizes, namely a left independent washing space and a right independent washing space (or a front independent washing space and a rear independent washing space); therefore, the clothes of different classes can be placed and washed in the two independent washing spaces at the same time; and if large clothes are needed to be washed, the partition plate 22 is taken down. In the figure, 25 represents two washing ribs of which the top parts are provided with grooves and which are connected with the inner wall of the roller in a sealed manner; 23 and 24 represent washing ribs; and 27 represents a water level sensor.
