Rotary drum washing machine for textiles has inclined inner and outer drums containing agitator locally increasing and decreasing pressure close to washing

摘要

The machine circulates the washing fluid, in part by agitation from a body inside, which alternately raises and lowers the water pressure close to the mass of washing, relative to atmospheric pressure. Axes of the two drums are inclined; they are more vertical than horizontal. The inner drum is symmetrical and driven in rotation. Motion of the surface exerting pressure within the drum, is linear or swinging.
