RADICAL GENERATING SYSTEM Russian patent published in 2005 - IPC

FIELD: manufacture of washing machines.

SUBSTANCE: proposed washing machine consists of radical generating system 300 combining bubble and ozone generating units 302,304 and 308 and radical replacement units in housing 310. Bubble generating unit 302 includes air pump 312 and working compartment. Air contained in working compartment is compressed and expanded under action of diaphragm 312a of air pump 312 made from elastic material forming mixture of air and air bubbles which is admitted to gas mixing chamber 306. First check valve 311 excludes return flow of mixture from gas mixing chamber 306 to bubble generating unit 302. High voltage is formed in ozone generating unit 304 for forming ozone from mixture contained in chamber 306. Second check valve 313 located between gas mixing chamber 306 and radical replacement unit 308 lets mixture pass selectively preventing it from return flow. Radical replacement unit 308 contains catalyst 308a in form of main, auxiliary and carrier catalysts. Main catalyst is TiO₂, MnO₂ or CuO₂, auxiliary is catalyst Pt or Pd and carrier catalyst is Al₂O₃, SiO₂ or MgO. Under action of catalyst 308a, ozone is decomposed into active oxygen radicals of first raw which react with water forming active oxygen radical of second raw containing OH group. Left-hand side wall 308c of unit 308 has ozone inlet hole 308d. Right-hand wall 308e has hole 308f for outlet of active oxygen radical of second row.

EFFECT: improved quality of washing; reduced amount of ozone.
