METHOD FOR WASHING AND WASHING MACHINE Russian patent published in 2005 - IPC

FIELD: washing equipment.

SUBSTANCE: method involves introducing into cylindrical tank washing solution under excessive pressure, said washing solution being formed as air-enriched divided stream delivered from free cavity under tank cover and adapted for forming air bubbles in washing solution; providing repeated pumping of washing solution through closed circuit extending from tank outlet end to tank inlet end to heat washing solution and increase percentage of bubbles generated therein. Solution "boiling" effect combined with movement and mixing of linen intensifies washing process. Washing solution is circulated along closed circuit including tank, water intake, filter, suction pipeline, pump, check valve, pressure pipeline, jet-bubble generator, and tank. Air is drawn for generation of bubbles from cavity under tank cover, is further directed through pipeline, filter, valve, jet-bubble generator into tank cavity to be delivered in the form of mixture of washing solution and air bubbles.

EFFECT: increased efficiency in washing of linen by means of water jet combined with joint action of washing solution and air bubbles acting upon linen.
